Every time when Spicy Girls and Pure Men go to Huowo Restaurant to eat and drink spicy food, do you ever think about what ingredients are in the spicy soup base of Huowo? In addition to Zhitian pepper, red pepper, salt, monosodium glutamate, chicken powder, bean paste, butter, salad oil, sesame oil, etc., the most important thing is the carefully processed ancestral gutter oil, which is said to be the exclusive secret recipe for addiction. It's really heavy. Don't think that we are small and fresh if we don't eat fire nest. In fact, the air we breathe every day is more flavorful than spicy fire nest to some extent.
Carbon monoxide, nitric oxide, nitrogen dioxide, ozone PM2.5、 It can be seen that dust particles, pollen, sulfur dioxide, etc. have been lurking around us, not to mention the blatant exhaust gas and black smoke on the roads and industrial areas, as well as toxic gases such as formaldehyde, benzene and ammonia. Over time, every mouthful of air we breathe may really be equivalent to a mouthful of our ancestral secret gutter oil soup.
With the increasing severity and popularity of respiratory diseases, more and more manufacturers at home and abroad have joined in the research and development of air purifiers. Even Xiaomi has already crossed the border. Lenovo Zuk has also launched PM2.5 detection instruments, not to mention well-known manufacturers such as Philips, Fujitsu, Sharp, etc. In addition to the traditional design, the air purifier in recent years has also introduced some new technologies to enhance the purification capacity and improve the simplicity of the user experience. For example, electrostatic dust collection technology and iron catalyst catalytic technology are introduced. Unlike traditional purifiers, which need frequent replacement of filter elements and membranes, the internal dust collection plate can be reused through water washing, greatly saving subsequent maintenance costs and processes. Another new form is the air purifier that we mentioned now: air humidifier+air purifier, which mainly focuses on humidification, and air purification is only an auxiliary function, so there will be some gaps between air purifiers with pure purification effect.
The Air Valley O2 air purifier is a product that Yiliang Technology has spent three years in research and development. Although it missed the best release time, the CEO has made constant adjustments and modifications to this product to make it more in line with the ideal form. There is a spirit of craftsmanship integrated into the product. Then let's take a look at the difference between this air purifier that allows technology to penetrate into art and other products of the same type? Can it be saved with unique function points, high-quality user experience and reliable cleaning ability when the release time is behind?
Appearance design
The appearance of the Air Valley O2 air purifier is described in official language as a combination of ancient and modern times. The beauty of classical culture is integrated with modern line aesthetics. The shape of ancient ceramics is in the original words of our editorial colleagues: pickle jar. Round and stylish, free and easy, the appearance and feel are good, and the power cord and instructions are attached. The power cord specification is 10A/250V, which is compatible with the standards of many regions.
From top to bottom, there are still power keys, Wi Fi connections and PM2.5 filter sensors on the front of the fuselage. The green packing belt in the middle can be disassembled into two parts: upper and lower.
The top of the fuselage is a human-computer interaction area, the middle is a display panel, and there will be two concentric circles of breathing lights beside it. Between the concentric circles of breathing lights is a ventilation slot. When the wind speed increases, you can clearly feel the fresh air blowing in the face.
The two small eyes on the top are gesture sensing areas.
Then let's take a look at the internal structure. Tear off the green seal and we will split it into upper and lower parts, as shown in the following figure:
The upper part is the circuit board area. According to the detailed photos below, the circuit board mainly builds air ducts and controls and monitors the normal operation of the whole machine.
There are four contacts on the edge of the fuselage, which are just corresponding to the four contacts on the lower part. The magnetic design is adopted.
The following figure is the metal contact of the lower part, which just corresponds to the upper part.
The lower part is the main component of filter element and filter membrane. It is divided into a triple structure from inside to outside.
Remove the filter membrane of the filter element of the triple filter mechanism, and the rest is the circuit board at the bottom, as shown in the figure below.
Please fasten the body chassis and the filter element and membrane chassis of the triple filter mechanism at the corresponding arrow position to ensure normal operation.
The following is a close-up of the triple filter structure.
If you want to clean or replace the three-layer filter screen module, please refer to the official instructions:
The following figure shows the official recommended replacement or cleaning cycle.
As for the inner layer, that is, the working principle of the humidification filter screen, the official website of Yiliang Technology also gave a detailed explanation. I have to say that after reading these schematic diagrams, the author reviewed the chemistry textbook in high school again. Since the Air Valley O2 uses a humidification mechanism, it filters water resources more than the ordinary air purifier. Although it is not as complex as the structure of the water purifier, after all, the latter is of drinking grade. However, if bacteria and microorganisms in the water are spread into the air without filtration, it is safer than not humidifying the air. Especially in the southern region, the air is humid and easy to breed bacteria.
Then let's take a look at the official structural anatomy of the air purifier and talk about other components.
Just now, we have mainly learned about the filter screen module in the lower part, and then continue to talk about other parts in the lower part. In the appearance diagram above, we not only give a close-up of the humidification filter screen, but also include the sterilization module. The combination of these two modules forms the innermost purification barrier.
Then let's take a look at the upper half of the circuit board structure of the air purifier. As it is not suitable for on-site disassembly, it is better to see the official drawing at a glance.
For noise reduction, BLDC brushless DC 36V motor is used for Air Valley O2 air purifier. It has proprietary wind wheel and air duct technology. In order to achieve an ultra quiet effect below 28 dB, a three in one combination of wind wheel core+rubber bag+wind wheel is introduced when the motor contacts the wind wheel. Effectively isolate the problem that the sound of the motor's own current is transmitted to the main body of the wind turbine.
Many consumers are expected to like to study the trend of their wind channels, as shown in the following figure:
The air enters the Air Valley O2 air purifier from the bottom of the fuselage, and after a series of purification and humidification, fresh and moist air is discharged from the top control panel area.
Interface operation and use experience
Referring to the main interface of the Air Valley O2 air purifier body, the official legend is explained as follows:
In the whole experiment process of this paper, only two states of light blue and green have appeared. The laboratory is a closed space for most of the year. It is worth mentioning the gesture operation mentioned above. Remember those little eyes right above? Moving up and down in the z-axis direction above it means to turn on/off the Air Valley O2 air purifier, sliding left and right in the xoy plane means to increase/decrease the wind speed, and sliding up and down horizontally means to turn on/off the concentric circle indicator light.
Connect with mobile phones
If I want to further monitor the use status of the humidifier remotely, or do I have any tools to help with the humidifier in the room control hall? The official offer of the Brilliant Air Purifier App can be found in our test mobile phone (Flyme system) built-in app store. Warm prompt, as shown in the figure below, pay attention to search keywords.
After installation, you can choose to register and log in the software.
After easy registration, we directly jump to the Wi Fi connection phase in the login interface. The user experience is not very good, mainly because if we turn off the positioning permission of the app, the system will not recognize the wireless network.
After the device is bound successfully, we will find an air purifier in the device list. Of course, we can also connect multiple devices. The problem is different from the scales and smart watches that I have experienced before.
If water has just been added, both the App interface and the purifier interface will show that sterilization is in progress.
In order to give readers a better understanding of the mobile phone App operating interface of Air Valley O2, the following is a comparison chart of the status of the air purifier obtained from the App end before and after purification, reflecting the actual air conditions in the test environment. The left side shows the values recorded at the end of the day after the work purifier started to operate, and the right side shows the values recorded at the end of the day. At the end of the following section, the final results of the 3 day test will be presented to all readers.
In terms of air volume, there are five gears. The maximum gear is changed to automatic mode by switching to the first gear, and then to the slowest wind speed mode by switching to the first gear.
Another advantage of mobile apps is that they can set the timing, but it's not humanized to know how many hours each level represents? Or minutes?
We can also monitor the triple filter module in real time, and the mobile app will tell you the wear and depreciation degree, and remind the user to replace it if necessary.
The other slot is that the real-time PM2.5 value of Shenzhen is 76, but as shown in the above figure, the control panel interface of the mobile app and the purifier body is displayed as 41, and the accuracy needs to be improved. In addition, as shown in the figure below, when the air purifier suddenly stops operating, it is generally necessary to add water, and both the machine and the App will receive system feedback prompts.
As shown in the figure below, the purifier has told us that we need to add water to it to further operate.
After a period of use, the depreciation rate of the filter screen module of the air purifier will change.
Actual purification effect
There are three evaluation standards for Air Valley O2 in this paper, formaldehyde concentration, humidity and PM2.5 index. The last two indicators can be monitored in real time through the display panel of the air purifier or the mobile phone app. The total working time of Air Valley O2 is 3 days.
Indoor environmental status before the humidifier is not running
The final impregnation effect after three days of work (humidity is 63%, PM2.5 index is 32)
The PM2.5 index was somewhat suppressed. When the author recorded the experimental results, the PM2.5 index hovered between 32-37.
summary
The Air Valley O2 is an air purifier that combines art and technology and purifies and humidifies the air in a soft way. In addition to the relatively heavy body, its shape and workmanship are worthy of its expensive price. The Air Valley O2 has some room for improvement in the control of the PM2.5 index. For northern regions, humidification function will be more popular.
After complaining about the advantages, the mobile app's operating interface is simple and easy to understand. The service life of the filter screen module is also relatively long among the products of the same type, which indirectly reduces the user's later maintenance cost and time.
