You can set the type of food to be saved and the number of days to save, and the box can be opened to expand the saving function; You can also set the sterilization frequency and opening time, and it will automatically sterilize; The box can also be deodorized automatically by adjusting the sensitivity of the electronic nose sensor. If there is any abnormality in the refrigerator, such as the temperature is too high or the refrigerator door is not closed properly, the cloud will push a message to the user to let the user know the storage environment of the refrigerator. A single charge can last about two weeks. If you set the deodorization frequency, it will automatically deodorize and sterilize according to the frequency. If there is any abnormality in the refrigerator, it will send a push message to the user through the mobile phone to let the user know the storage environment of the refrigerator.

Why can the refrigerator box get rid of odor?
After food is put in the refrigerator, cells still need to breathe. The bacteria in the refrigerator often exceed 800 times the normal environment, and the ripening gas such as ethylene released by the fruit itself, so even if it is stored in the refrigerator, the food will rot, but the low temperature environment will slow down the decay rate.
The refrigerator box can be ionized to produce ozone and negative ions. Ozone is highly oxidizing and can be sterilized by chemical reaction, while negative ions are the physical characteristics of refrigerator box, which can achieve the effect of purifying air. Just as people feel the air is fresh after a thunderstorm, it is precisely because thunderstorms produce a lot of ozone and negative ions.
The core hardware of refrigerator box adopts Japanese figaro electronic nose sensor. There is a tin oxide (chemical formula: SnO2) coating on the electronic nose, which has poor conductivity in clean air. When food smells, gas molecules will be mixed in the air, and the air conductivity will increase. Based on the difference of conductivity of different gases, the box sends the collected gas data to the cloud, and the cloud will start the ozone negative ion emitter after recognition, thus achieving the effect of deodorization and sterilization.
The appearance of this Haier refrigerator box is very similar to the drinking cup we usually use. The white shell consists of two parts. The top is a white plastic shell painted in piano style. The bottom is a metal mesh bottom cover, which is a sensor on the tall. It can sense all kinds of harmful chemical gases. The bottom is a non-slip and moisture-proof bottom pad, so you don't have to worry about the damage of moisture and water stains on the sensor when you put it in the refrigerator.
The circuit board inside can be seen through the ventilation hole at the top.
After disassembling the machine, it was found that there was a WiFi antenna module at the top, mostly a box of lithium batteries and a very complicated sensor monitoring circuit module, which was full of materials. But it can also be seen that this box is actually not waterproof, that is to say, water can't be poured through the vent hole at the top, but the general moistureproof is completely fine. At present, the health box has been invested by Haier and obtained the trademark right of Haier. It could have been sold with Haier refrigerator, but Chen Dong objected. Due to the tying mode, a large part of them may be "zombie users", which is not conducive to data collection and cannot maximize the value of products.
