1、 Xiaomi: Why is it blackened?

     Speaking of millet, it can be said that everyone knows, everyone knows, and there is no shortage of Mi Hong and Mi Hei in this part of the population. Since the release of the first Xiaomi mobile phone on August 16, 2011, it has quickly occupied the market, It has won the favor of users. Xiaomi is considered to be the product with the most "Apple" temperament, and Lei Jun is also titled "China's Jobs". However, his thirsty marketing mode also made the rice noodles hard to compete Love begets hate, and there is love in hate, so Mihei appeared - "Eat, sleep, and black millet", as if it had become a conservative track overnight. These "black" people are afraid of the world by hiding millet and magnifying its shortcomings Not disorderly, while holding millet to do a "Tianji horse race", attracting users' attention to win traffic; Then, its "good quality and low price" has become the "target" of all major mobile phone manufacturers. After all, Xiaomi is like this in the market "One stir" made the leaders lose their profits, so they were ready to kill Xiaomi. But the truth? Users really get the benefits they never had before. After all, everyone has a stroke in their heart Scale. Who can imagine that if there were no Xiaomi, would the hardware products still be so cheap and exquisite as they are now? To be fair, after using the miui system, will you call it Okay? We cannot deny that the existence of Xiaomi has led the trend of a number of digital products, such as Xiaomi water purifier. Before that, did we really care about the water quality?

Although Xiaomi has been "controversial" and "questioned" during its development, it is still young and has a long way to go!

2、 Talk about Xiaomi water purifier: why is it worth expecting?

             1. Why did Xiaomi make a water purifier? Ma Yun once said that air is no good, water is no good, no matter how good mobile phones are, every entrepreneur has the obligation to pay attention to the environment; In such an environment, I personally think that the advent of Xiaomi Water Purifier is not only the place of conscience, but also a deeply moving feeling.

             2、 What's good about Xiaomi water purifier? Lei Jun once said, "When Xiaomi was founded five years ago, I hoped that Chinese products could get rid of the image of low price and low quality, and really change the world's view of Chinese products. We should take the lead in making high-quality products, hoping for one Days, Xiaomi can drive the progress of the whole industry, just like Sony in Japan and Samsung in South Korea. New domestic products, in short, mean that domestic quality should challenge international brands, which is the new domestic products movement we advocate! ", Patriotism first The first choice is domestic brands; Of course, Xiaomi has a higher cost performance under the same hardware than a product with a starting price of RMB 3000 or 5000; In addition, you don't have to worry about the powerful follow-up service.

             3. Must buy domestic products? Can the quality be bearable? This question is a bit difficult to answer. How about taking a look at the actual experience?

3、 Look at the parameters: know what is, then know why

             Sharp tools make good work. Therefore, before starting the experience, you must first understand the parameters of this millet water purifier. You can only understand it if you go deep into it.

4、 Talk about appearance: mainly about temperament

             [Its packaging]

         package It is very large. As shown in the picture, the appearance we see is the same. The front is printed with black MI words, and there is a handle on both sides; The top of the side is printed with indicators such as fragile, rain proof, stacking layer limit, no stepping, etc Indicative pattern; At the same time, the label of millet water purifier (400G) is attached, which simply and detailedly lists its model, size, gross weight, net weight and manufacturer's information.

         Its gross weight is close to 30 jin, which is not particularly heavy. It is more suitable for an adult man to carry it.

                   [Its true appearance]

             six Over the years, Xiaomi has been adhering to the simple and fashionable line, so the name "Rebus" is well deserved. It still has the same pure white body as the kitchen style in appearance, and only The size of A4 paper is just like the current popular A4 waist. Although the outer package is very large, the water purifier itself is very small, with a size of only 205 * 410 * 260mm and a weight of only about 20kg.

         mutually Compared with the over kitchen style, under kitchen style brings us convenience and also reserves more space. The fuselage adopts an integrated full surround design, with concave and convex texture on the surface, which is more qualitative than the smooth surface It feels inside. Fortunately, it is under the kitchen and can be placed in a relatively sealed space. Otherwise, the smoke in the kitchen will make it difficult to clean the surface. It seems that the cleaning of the appearance has been solved.

         Its full enclosure design, viewed from the outside, is a white cube box with rounded corners. There is an indicator light on the top of the front and a gray MI logo near the bottom.

                   [Its details]

             There is a light blue upper cover on the top of the fuselage, which is buckled with the fuselage to form a complete whole. It can be seen from a recent photo that there is 400G under the MI word at the bottom of the front of the fuselage. That is to say, the water purifier can produce 400 gallons of clean water per hour, and the flow rate of clean water is 1.0L/min.

         On the back of the upper cover, there are QR codes of mobile phone APP, WiFi reset procedures and precautions during use.

         The integration at the bottom of the back is very rich. Like the yellow label on the outer package, the detailed parameters such as product model, water purification flow, product name, rated frequency and power, and manufacturer of the under kitchen water purifier are printed, which is more comprehensive than the information on the label on the outer package.

         collection The interface mainly includes water inlet pipe, pure water pipe, concentrated water pipe (waste water), power line and clean tap lead. The pipes are made of DMT food grade materials imported from South Korea, and are also marked with labels on the water pipes The color and thickness are also different. The advantage is that errors in installation can be avoided to the greatest extent. If you are used to it, you can quickly identify and install it by just looking at the color and the diameter of the water pipe.

         The lead wire of the clean faucet is made of dark gray soft glue, which is soft and can be connected to the stainless steel clean faucet. It is mainly used to supply power to the light ring of the faucet. The current water quality is achieved by controlling the color of the light.

         The middle of the bottom is also carved with MI words, and there is a curved white anti-skid silicone pad around each side; There is a groove on both sides of the bottom for moving the water purifier. The design is very user-friendly.

                   [Its core values]

             Although the appearance of a water purifier can attract users, whether it can achieve the desired effect depends on its "core members".

             1. Inside the fuselage.

             The under kitchen water purifier uses a four level filter element purification effect. Open the light blue upper cover on the top of the machine body, there are four cylindrical grooves on the left side, and 1, 2, 3, and 4 are marked from bottom to top, which are mainly used to install four filter elements with different functions.

         concave Its operation guide is printed on the left plane control panel of the slot, and there is an indicator light and two buttons for selecting and resetting at the lower right corner, which can be touched. If the orange light is on, the filter element is about to reach its service life And needs to be replaced in time; However, for the under kitchen water purifier, it is not convenient for us to bend down and open the cabinet frequently to check the indicator light, so this water purifier also has the WiFi function. By installing the mobile phone APP After that, you can see more information about the water purifier on your mobile phone in a timely manner.

         Internal structure of the groove.

                  2. Filter element shape and function.

             In fact, I mentioned earlier that the so-called water purifier is to purify the water quality and improve the drinking water health of users. In other words, the tap water will be transformed into a harmless effect after purification, which is also a "pain point problem" for the water purification industry. Therefore, Xiaomi's under kitchen water purifier adopts RO reverse osmosis purification technology with 4-stage filter element, and the filtration precision can reach 0.0001 μ m.

         The four filter elements are printed with Arabic numerals 1-4, as shown in the figure below. From left to right, they are PP cotton filter element, pre activated carbon filter element, RO reverse osmosis filter element (400G) and RO reverse osmosis filter element (400G). Among them, the volume of RO reverse osmosis membrane No.3 is obviously larger than others, which aims to speed up the water purification speed to reduce the waiting time of users.

         The four filter elements delivered from the factory are vacuum packed. Each filter element has a code and tells which filter element it belongs to, such as the "rear activated carbon filter element". When installing, it corresponds to the number on the groove on the top. Correspondingly, the back of the digital code is printed with the specifications, service life and instructions of the filter element, and the amount of information is still very large.

         The filter element is cylindrical in shape. The top is different from the bottom. The interface also adopts an integrated design. No additional connecting water pipe is required. Just put it into the groove according to the coding order to achieve plug and play.

         The top of the filter element has a "straight line" projection, which can be slightly pressed and rotated during installation to fix the filter element in the body. There are different codes and English codes on the top of each filter element for easy identification.

         Installation diagram of filter element.

         say The specific installation steps are as follows. The installation method of this kitchen type water purifier is different from that of the common water purifier filter elements. Relatively speaking, Xiaomi's filter elements are simpler and faster to install. The numbered filter elements correspond to the body recesses respectively Put the slot code in, slightly press the "straight" projection on the top of the rotary filter element, and rotate it 90 degrees to the right to complete the installation. It is placed horizontally with the font on the panel, and can be completely rotated to the position perpendicular to the font Fix it and close the light blue upper cover of the fuselage.

         The independent stainless steel pure water faucet is made of 3.4 stainless steel. After precision casting, the inner wall is clean and smooth; At the same time, it also comes with three-way ball valve, rubber plug (plastic plug) and rotating screw for fixing, which can effectively fix the faucet and prevent water leakage during use.

         Different from ordinary faucets, this faucet is equipped with a lead wire, which has a section in the faucet and the body respectively. The lead wire of the faucet is integrated with the LED halo lamp. Before power on, the lead wire of the body and the faucet is connected. After power on, the color of the halo will visually distinguish the quality of water and whether the filter element has reached the service life.

                   [Instructions for Use]

             The manual explains the use and operation in detail, but there is no detailed installation guide. It may be that this under kitchen water purifier is provided with on-site service by professional masters, so it is omitted; For a "kid" like me who has strong hands-on ability, the lack of installation guide is slightly inadequate.

5、 Try app: it's very humanistic

         Xiaomi's miui system can be called the Apple of Android. It is not only smooth, but also its smart products can be managed with only one APP. The adding process is very simple. When the power is connected, the water purifier (under the kitchen) device can be automatically searched in the Xiaomi Smart Home APP, and the next step of the fool type can be completed.

         There are detailed instructions and reset methods for faucet in APP, and filter element can also be purchased through APP.

         This app with WiFi function can view the water quality in real time through mobile phones.

         It can also display the time of using the water purifier and the amount of water used each time in detail, and can also understand the service life of the filter element in real time.

6、 Talk about functions and features: you will fall in love with them once you try

             What is RO reverse osmosis technology: it is the only truly effective filtration technology that can remove heavy metals, antibiotics, and organic substances. It can help you remove rust, scale, heavy metals, bacteria, antibiotics, and unpleasant smells from your tap water by cooperating with the four level filtration system of layer by layer purification.

             filter Service life of the core: Generally, the PP cotton filter core can be used for 3-6 months with a filtration accuracy of 5 microns; The pre activated carbon filter element can be used for 6-12 months, and the post activated carbon filter element can be used for 6-12 months The iodine adsorption value of each filter element can reach 1100mg/g; These three filter elements are relatively cheap. The most expensive one is RO reverse osmosis filter element, with a filtration precision of 0.0001 μ m and a service life of up to 18-24 months, which is also the most durable level 3 filter element. Of course, this is only theoretical. According to the water quality, region and usage, it can be extended or shortened on this basis.

             Small The originality of the rice kitchen type water purifier is that it has two modes: ordinary mode and lifting mode. The pure water flow of the ordinary mode is 1.0L/min, and the proportion of pure water and waste water is 1:1; The pure water flow in lifting mode is 1.4L /Min, the proportion of pure water and waste water can be as high as 2:1。 In other words, when the water purifier detects that the water quality is good, it will start the lifting mode. However, due to the large output of this water purifier, the noise is also higher.

                   The RO reverse osmosis filter element with code 3 is also the filter element with the highest gold content in millet water purifier. Its filtration precision reaches the nanometer level, and even tiny bacteria can be filtered out, which also brings about the loss of trace elements contained in water.

7、 Look at the usage scenario:

8、 Small test installation: simple enough that the master can take a vacation.

             security Installation is also an important link. The pipes of this water purifier are "2 white and 1 gray". The two white pipes are one thick and one thin. The thick one is the water inlet pipe, which should be connected to the home tap pipe, and the thin one is connected to the tap Color water pipe (concentration water pipe, also waste water pipe) has the same diameter as the white water suction pipe. Because it is under the kitchen, it can be directly led to the sewer. If the concentrated water pipe is used as a pure water pipe, it will increase our kidney Burden of functions.

         Usually, the "vegetable washing basin" in our house has two taps and soap boxes. What we need to do is to remove the soap box so that we can place the pure tap on it. When connecting the pure water pipe to the faucet, some small accessories are needed, as shown in the following figure.

                   Installation method of swivel:

             On the other side of the "vegetable washing basin", you need to use the screws attached to the water purifier to tighten it. The attachment of a round cylinder (with round holes on both sides) has different sections from top to bottom, one side has a slip ring, which should face the "vegetable washing basin", and the other side has a smooth section, which can be connected with the screw to ensure the smooth rotation of the screw. The faucet lead can pass through one of the small round holes.

         After fixing the screws, the operation method before installation is to connect the pure water pipe with the faucet and tighten it.

                   Installation method of three-way ball valve:

             Normally, we don't need to use this ball valve, just connect the tap pipe and the faucet pipe. The main function of the three-way ball valve is to connect the faucet pipe and the pure water pipe of the water purifier at the same time, and realize the flow direction through the rotary switch of the valve.

         It is OK to install and tighten in the way shown in the figure below. There is no technical content in it.

         The rotary switch changes the direction of the water flow.

9、 Notice for use: a few small things you have to know.

             In the process of use, we can check the water quality and the service life of the filter element through the mobile phone APP and the panel of the host, and we can also easily master the LED light ring of the pure faucet. When the light ring is blue, it indicates that the water quality is normal. If it is orange red when discharging water, it indicates that the water quality is unqualified or the filter element needs to be replaced.

         As shown in the figure below, the water from the gray concentrated water pipe (waste water pipe) can be directly led into the sewer. The water just flowing out is black, which is caused by the carbon in the filter element. Don't worry. Just let the water flow patiently for a while to wash the filter element clean. You can also check the light ring for confirmation.

10、 Check the data: there is indeed a surprise.

             stay In terms of detection, Xiaomi TDS water quality detection pen is used to check the values. Although the TDS water quality detection pen does not represent the effectiveness and reliability of water quality, it can also simply reflect the harmful heavy metals in water quality Content. As shown in the figure below, I use tap water, concentrated water and purified water to test in turn. It can be seen that the value of tap water is 270, the value of concentrated water is 310, and the value of pure water is 14 The water purification effect and timeliness of this water purifier are very good.

11、 Summary: a thankless summary.

             before Let's talk about its advantages: despite the praise for the delicate appearance of this water purifier, its hidden installation under the kitchen can save space without affecting the overall layout, such as the A4 size floor area and less than half a meter The height is completely suitable for the kitchen of most users' homes; The large flow rate of 400 gallons is even comparable to that of the water purifier of 3000 or 5000 yuan, and the unique lifting mode that can increase the flow rate by 40% makes the water flow faster and the waste water more Less; The precision of RO RO direct drinking function is up to one thousandth of a micron, which makes many water purifiers flinch, and it also has automatic flushing technology to avoid the reduction of water flow due to blockage; Its exquisite independent pure faucet material is more Good, and it does not affect the use of tap water. Of course, the filter element is better and convenient. However, more importantly, as Xiaomi's smart ecology, it is also an intelligent water purifier, which can be accessed through lights, mobile phone apps and panels It can intuitively see the water quality and the service life of the filter element, and can understand the water quality in the home even remotely.

             Let's talk about its disadvantages: the instruction manual is the first thing I want to say, because although this water purifier has a dedicated and intimate master, for someone like me who has strong hands-on ability, it is better to write the installation process in the instruction manual; It is hoped that the noise caused by rapid water exit can be further reduced by increasing the width and softness of the anti-skid mat.

             In general, as a part of Xiaomi Smart Home, this water purifier is worthy of our attention; More importantly, its quadruple filtration can make every drop of water we drink fresh and healthy, starting with the millet water purifier.
