preface:

When the haze shrouded the land, people woke up to the need for clean air. All kinds of clean air were popular in China for a while, but I want to say that people also need clean water. The author once worked in a water supply equipment company (the headquarters is just next to Qingdao Haier), and had a better understanding of the current situation of tap water. It is necessary to understand how tap water comes before the article begins, because it will break all your fantasies about clean water.

It is well known that natural precipitation, lakes and rivers contain suspended solids, colloids, dissolved substances and other impurities, which cannot be used for direct drinking. Here, it is called raw water. The raw water from the source area is pressurized by the pump room and delivered to the waterworks for mixing, reaction, sedimentation, filtration Disinfection and other processes meet the national mandatory standards for tap water, and then the above processes are pressurized and fed into the municipal pipe network. There is not much problem. At most, there is rust sediment and secondary pollution caused by the aging of the municipal pipe network. Of course, the water in the municipal pipe network cannot directly reach your home. In order to prevent negative pressure from adversely affecting the municipal pipe network, If I remember correctly, a presidential order was issued in 1999, and any pressurized equipment such as water pump shall not be connected in series with the municipal pipe network (if any god can remember the number of presidential order, please leave a message for correction). So your community will basically have a reservoir or water tank for the secondary pressurization of tap water. Of course, non professionals and designers do not know the specific location. You may think that the pool and water tank are clean, clear and even beautiful, but it may actually be like this

The pool and water tank are a dead corner, and few people pay attention to it. The prevalence of cats and mice here is worrying. What's more, the water tank body soaking incident similar to Lan Kere has occurred in Fuzhou, Guangzhou. The water in the pool and tank comes to your home through secondary pressurization. Do you dare to drink it??? So you must have a water purifier, which is not recommended but necessary. It's a bit creepy to see those unknown places. Let's calm down and start our products today - Haier Intelligent Clean Faucet.

Unpacking:

▼ The white outer package is dotted with light blue shading, which is simple and fresh, and the front highlights the pattern of intelligent water tap LOGO， The right side is designed with a portable pull ring, and the side pull design is not limited to one pattern.

▼ Take out the product manual and certificate on the top layer, and you can see all the hardware and accessories of the intelligent clean faucet. From left to right, they are: adapter (adapter) * 4; Filter element * 1; Switcher * 1; Raw material belt * 1; Battery * 1; Installation wrench * 1 filter * 5, universal joint * 1. Is it complicated? I feel dizzy when I look at these accessories. I think it is the most intelligent hardware accessories I have ever seen.

▼ So many members come to Zhang's family photo and are very happy. Let's all come out to bask in the sun, because most members may lie in the box all their lives. Such as raw material belt, adapter, etc. It has to be said that the product has been carefully considered in terms of adaptation. It is not only equipped with mainstream interface adapters, but also equipped with universal connectors and installation wrenches.

Details:

▼ The whole body is composed of non-toxic ABS, non-toxic rubber and PP resin, and the material is relatively safe. The color matching adopts white as the main color, and is embellished with sapphire blue.

▼ Unlike the relatively fixed water outlet mode of traditional water purifiers, Haier's switcher can provide switching between purified water and raw water outlet modes.

▼ How smart is the smart host on the top of the filter element? The author will show it in the application section.

▼ Filter element adopts modular design, but real-time replacement can make DIY any combination with different requirements. Such a small body can provide six layers of purification, including prefiltration, ion resin, activated carbon, PP cotton, carbon fiber, and ultrafiltration.

▼ The main body of the intelligent cleaning faucet is composed of the switch and the filter element, which is very convenient to combine. After the interface is aligned, the combination is successful after 90 degrees of rotation.

▼ Although Lei Feng.com indicated that a strong hands-on ability was needed before the arrival of the product, and I made full preparations, I still lost a lot of energy during the installation. The main problem is that the bubbler of the raw water faucet cannot be removed. Therefore, none of the tools can be removed intact.

▼ After unremitting efforts and successful installation, I like this design, which not only effectively avoids the risk of water leakage, but also can be installed wherever I want. It is different from the traditional water purifier, which requires fixed waterways, so now the author also uses filtered hot water.

Application:

▼ The installation and registration of Zhishui's APP is still very user-friendly, one click installation, SMS verification and registration. It seems that every post-80s generation has a complex about Haier, and I am no exception. However, it is disappointing that the word "intelligence" in many Haier intelligent products I use seems pale and immature. This may be the pain of intelligent transformation of traditional industries.

▼ The main interface prompts the current water quality, net water quantity, filter element status, water temperature and other information. If the current water quality is poor or is used improperly, reasonable optimization suggestions will be given.

▼ Purified water volume directly records the daily water consumption of Haier clean faucet, and can show you the water consumption status according to different time periods.

▼ The list and sign in function encourage users to use more purifiers to strengthen water quality safety protection.

▼ The map can not only give you the location information, but also provide the water quality of the nearby areas. At the same time, you can share the water purifier with your family.

▼ Haier Mall and one button repair report are built in the setting column to easily solve filter element purchase and after-sales problems.

The consistent view of the author is that no matter how intelligent the intelligent hardware is, it should do its job first. Otherwise, intelligence is a waste. Therefore, a mule or a horse can come out for a walk. Before entering the test chapter, introduce the possible factors that affect human health in tap water.

1. Sediment and rust impurities caused by pipe network aging.

2. Alumina, commonly known as alum, may be added to the process of tap water to accelerate precipitation. Residual aluminum ions are harmful to health

3. The tap water is usually disinfected by chlorine gas. In order to prevent bacteria from breeding in the process of conveying the tap water, a small amount is usually added. Residual chlorine has strong oxidizing property and is also harmful.

4. Chlorine disinfection cannot meet the standard of direct drinking, and there will be more microorganisms in the water.

5. Secondary pollution during transportation and storage.

6. Heavy metals.

7. PH value

8. Hardness

Before the test, the test environment is introduced. The author pays more attention to water safety, so when the tap water enters the home, it is installed with a pre filter to protect the safety of electrical appliances such as water heaters. At the same time, a secondary pre filter and a water purifier are installed in the kitchen. As the household prefilter cannot be removed, the next test effect is not very obvious. How about the water quality treatment effect of Haier's intelligent purification faucet? Who can be better than the traditional off-line water purifier?

First, compare the TDS total dissolved solids. Its value represents how many milligrams of soluble solids are contained in one liter of water. Generally, the TDS value of tap water is about 200. In the following figure, the measuring cups from left to right are raw water, Haier water purifier, and a desktop water purifier. It can be seen that the difference of TDS values after filtration is not large, indicating that the water quality is good. Haier's performance seems a bit disappointing.  

The Tds value can express the amount of impurities, while the electrolysis test can help us analyze the types of impurities. (Electrolysis cannot be used as a standard to measure the quality of water.) Through electrolysis, we can visually see the impurities filtered by the two filters.

In the residual chlorine test, the purification capacity of the two purifiers for residual chlorine is basically the same, while the residual chlorine content of raw water is slightly higher

In the instruction manual, only the ultrafiltration of the filter element is briefly introduced. If Haier is not sure whether ultrafiltration is the general interpretation (RO) of ultrafiltration in the market, it has to do a heavy metal test. These two types of water purifiers cannot completely filter out heavy metals, that is, they do not use pure water technology. As far as the filter element is concerned, Aihuipu is better than Haier in filtering heavy metals.

There is basically no difference between calcium and magnesium ion filtration. Many experts have been arguing about which is better for human health: mineral water or pure water. This is a very complicated problem. The author suggests mineral water instead of rooting.

Although theoretically, the purifier generally does not change the acidity and alkalinity of drinking water, but the PH value is an important indicator, so it is still measured that the PH value of domestic drinking water is set at 6.5-8.5 according to the national standard. There are many different views in the industry on whether neutral or slightly alkaline water is more conducive to health. Well, just to tell the truth, the water filtered by Aihuipu is closer to neutral, Haier is slightly alkaline.

Conclusion: In general, Haier's intelligent cleaning faucets are sufficient to meet the general domestic water demand in terms of design, intelligent application and purification functions, and they are inexpensive and do not occupy space.

advantage:

1. Small and delicate, small space, safe material.

2. It does not need professional installation personnel to install it, and it is convenient to carry it. You don't have to worry about water quality anywhere.

3. It is directly installed on the faucet without external power supply, avoiding risks such as leakage.

4. It is more intelligent, understands various parameters of water quality in real time, and gives optimization suggestions and filter element replacement reminders.

5. Modular design and DIY combined filter element can better meet different needs, and filter element replacement is simpler.

6. Good quality and low price.

Disadvantages:

1. There are too many spare interfaces, which are considerate but wasteful. It is recommended to equip interfaces according to user needs.

2. The presentation of water quality parameters is not comprehensive enough, only TDS, water temperature and other parameters are given.

3. The faucets in ordinary families are all metal in appearance. When Haier is installed with ABS material, it always makes a strange mismatch.

4. The parameters are not presented to users in real time, and the sensitivity of water temperature needs to be strengthened.

I hope you can correct me.
