Zhimi fresh air system is a new fan product recently released by Xiaomi ecological chain company smartmi Zhimi science and technology. Following the crowdfunding, this product has been added to millet products. At the same time, smartmi Zhimi signed a strategic cooperation agreement with Suning. , This product will be sold on Suning's e-commerce platform on June 1. It will open a 0-yuan booking on the platform on May 19th. Zhimi fresh air system has a fresh air volume of 220m?/h, and adopts a triple progressive filter design, which can not only efficiently filter PM2.5, but also play a role in ventilating and diluting indoor formaldehyde. Accessories family portrait. Fuselage from all angles. Screen close-up, using OLED full-fit technology screen, with a large viewing angle, and integrated screen brightness, mode switch two touch buttons. The air inlet on the back of the fuselage has an electric opening and closing baffle mechanism that automatically blocks the air inlet when it is turned off to prevent the entry of outdoor material into the airframe. To dismantle the first step, first pull out the filter cartridge on the side of the fuselage. The filter element adopts a double-layer composite structure design. The white side is a medium effect Merv12 filter. It mainly filters PM2.5, dust, pollen and other large particles; the blue side is a HEPA13 filter, can filter PM0.3, some bacteria, some germs Wait. Stainless steel primary effect filter can be repeatedly used to flush, mainly blocking dust, catkins and other external substances. Through the cartridge filter cartridge drawer can remove the other side of the baffle, and the computer chassis, the baffle is not a one-time design, but can be repeatedly removed and installed. According to the actual installation, the baffle can be installed on the left or right Side, so the filter cartridge can be pulled out either left or right. Remove the bezel screw. You can see the spring inside the baffle to support the kneading bayonet structure. In addition, there is a magnet at the red box mark so that the machine can detect whether the baffle is in place. The machine cannot run without the baffle installed. The design is very intimate. . Remove the sensor cover at the bottom of the fuselage. Remove the screw and jumper, remove the particulate sensor and carbon dioxide sensor respectively. Close-up of the particle sensor, same as the components used in millet air purifiers 2S, MAX and other products. First unscrew the back shell screws. Basically, two people are required to separate the back shell from the main body. However, because there are still several sets of connection between the back shell and the main body, care must be taken when disassembling. The vent flapper assembly connects power and commands through the outside. The inside of the back shell is removed after the vent flapper assembly is removed. There is a sealing material around the vent to prevent rain and other liquids from seeping into the body. Remove the baffle assembly screw. Here you can see how the baffle works. Remove the main body of the back shell, the fan part has been impressive. Continue to unscrew the fixing screws and remove the fan and fan housing. The PCB on the back of the screen where the fuselage screen is located. Close-up of the back of the PCB: At the top, you can also see the Wi-Fi module with the 'mi' logo, which supports the product interconnection function, realizes the connection with the Mijia APP, and controls the IoT. Frontal close-up of the PCB version: There is a translucent plastic ring assembly on the front. Similar to the softbox used for photography, the light of the bottom 16 LEDs is evened out, so that the overall appearance of a uniform color aura is used to prompt the user. Current indoor air quality situation. Remove the plastic part, you can see the circular array of LED lamp beads. The remaining part of the fuselage shows that similar to snail-shaped air ducts occupy most of the area, guide the filtered air to the air outlet above the fuselage, and reduce the wind noise generated when the wind direction changes. The strainer on the top of the spiral air duct mainly avoids indoor dust, debris, etc. falling into the air duct. Front view of a snail air duct. Next remove the cover of the power box. Remove the power board. Power board close-up. Started to disassemble the axial fan. After removing the fan, remove the blower housing. Fan show. Brushless DC blower supplied by Nederland. With all the components displayed, it is difficult to imagine a new fan that seems to be uncomplicated. It will contain so many components inside. The overall dismantling down, you can see the 1499 yuan Zhimi fresh air system has a very rigorous and sophisticated details of the design, in the case of a cramped cost, but also in the drawer bezel, OLED screen and sensors and other aspects of a very user-friendly design , it can be said to be very sincere.
