When you use the refrigerator to refrigerate, have you ever encountered such problems: the fresh-keeping time of vegetables is too short, and within a few days, the fresh vegetables are rotten; How can the odd smell of leftovers and fruits not be eliminated? Xiaomo has the same problem at home. Although many people have checked on the Internet to remove the peculiar smell of the refrigerator and extend the fresh-keeping time, they still can't get a thorough solution. Charcoal bars are too expensive, and some accessories have no obvious effect. I got a smart refrigerator treasure these days, which can specifically remove the strange smell in the refrigerator, extend the fresh-keeping time of vegetables and fruits, and degrade pesticide residues. How about such a high-tech product?

　　 Appearance design of high-tech products

Wokesmart brand was founded in 2014. In December of that year, the first generation product was released. In August 2015, the dual mode sterilization smart refrigerator treasure was released. Xiaomo got the latest product. The whole product looks very scientific and technological. When I put it in the refrigerator at home, my mother also asked: what is it, twinkling and twinkling. I said it was a refrigerator treasure for removing odor. My mother said after reading it, the technology is really developed and fashionable now.

Since it is an intelligent refrigerator robot, it naturally has something to do with technology, and the packaging style of refrigerator is also very simple. The front side shows the appearance of the product, which at first glance seems to be a small refrigerator. From the outer package of the product, we can see that the product is not big, and the palm is almost big.

The side of the package gives the characteristics of the product: dual mode intelligent antivirus, double extension of fresh-keeping period, effective removal of refrigerator odor, and accelerated degradation of pesticide residues. There are many functions, but do you understand the principle? It doesn't matter if I don't understand. I'll explain it in detail later.

On the back of the package are some instructions in both Chinese and English. It is important to remind that the refrigerator treasure intelligence can not be put in the freezer when it is used in the refrigeration of the refrigerator. Is there any smell in the freezer?

In terms of accessories, there are really few refrigerator treasures. In addition to one data line, there are instructions and certificates. There is also a layer of black sponge inside the box to prevent the refrigerator from bumping.

On the whole, the workmanship of the refrigerator treasure is very exquisite. The whole body is made of aluminum alloy, and the upper and lower covers made of ABS are equipped on both sides. The height of the product is about 15cm, while the diameter is only about 6cm. It can be said that it is very compact and easy to put in the refrigerator freezer.

The top and bottom of refrigerator treasure are made of ABS plastic material, which is also intended to better release ozone generated. If I don't introduce it to you, you will never think that it is used to remove the peculiar smell of the refrigerator. On the contrary, it is more like a small Bluetooth speaker.

The aluminum alloy body in the middle has two control buttons. The upper one is the switch button, the lower blue button is the deep sterilization mode, and the middle circle is the LED light display area. Both switches are realized by gently pressing and cycling. The bottom is equipped with an ozone release window, which is actually an aluminum alloy mesh. The disassembly at the back can see the actual effect.

There is a Wokesmart enterprise logo at the bottom of the refrigerator treasure, without any other elements. The frosted surface is very comfortable to touch.

The ABS cover at the bottom has four screws to fix the body, and the disassembly starts from here. ABS material has excellent skid resistance, which can also prevent the product from slipping in the refrigerator.

Although it is a cylinder, the refrigerator body is not a cylinder. On one side is a flattened aluminum alloy body. At the bottom is a rubber pad that fastens the USB charging interface and the recharge button to prevent moisture and moisture from corroding the interface of the refrigerator. The refrigerator has a built-in 2600mAh, which can work for two months without problems.

The workmanship of the refrigerator treasure is quite exquisite. The oxygen oxidation treatment similar to the iPhone, the all metal shell, and the ABS plastic materials on both sides of the upper and lower sides have excellent waterproof and corrosion resistance. What about its internal structure? How about the workmanship? What about the chip? What are the technical advantages? Let's take a look at it.

　　 Analysis of refrigerator treasure and its working principle

First, break the four small screws at the bottom, and you can easily remove the aluminum alloy fuselage outside. We can see that there is a plastic ring in the middle of the ABS plastic material at the bottom. With this ring, the sealing performance is guaranteed. The black body has eight small screws fixed on the circuit board inside, which protects the circuit board well.

There is a seal label on the black plastic fuselage, which indicates the production date: May 2016, a relatively new product.

At the bottom, we can see a stainless steel plate, which is an integrated negative ion and ozone generator. After power on, the ozone and negative ions of the integrated product will gradually diffuse to the refrigerator to kill the bacteria in the refrigerator, so as to clean the air in the refrigerator and remove the odor.

The black plastic bucket inside can clearly see the USB charging interface and reset button. After breaking the black plastic bucket, the USB interface and recharge button inside can be seen more clearly. At least until now, the internal workmanship is still very meticulous.

Breaking the black cylinder, we can see the rechargeable lithium battery inside. Although there is only one battery, its 2600mAh battery capacity is enough for Xiaobao to work for at least two months. The blue lithium battery is the body marked with some battery parameters that can be checked.

After removing the lithium battery, the circuit board inside will be displayed. Judging from the above resistance and Bluetooth module logo, the quality of the NDK crystal oscillator with Murata capacitance and inductance imported from Japan is guaranteed. The chip board placement date tells us that the product was produced in January 2016. And from the point of view of the solder joint workmanship of capacitance and resistance, it is more sophisticated. It can be seen that its OEM patch companies are relatively formal, and the repair rate is generally low.

Finally, we took apart all the aluminum alloy rings, and found that the wall thickness of the aluminum alloy screen and the entire aluminum alloy shell was about 3mm, which made us very familiar. It is not easy to break even if you fall on the ground carelessly.

We know that the peculiar smell of refrigerators is nothing more than the cause of bacteria breeding, and the short fresh-keeping time of vegetables is also the cause of the destruction of organic tissues of vegetables by a large number of bacteria. How can refrigerator treasure achieve its sterilization function? The refrigerator treasure can continuously emit ozone and negative ions through the ozone and negative ion generator. Little friends who know something about biology will say, isn't ozone smelling like rotten eggs? And will ozone have a strong oxidizing effect on people? The national ozone concentration safety standard is 0.15PPM, while the ozone release concentration of refrigerator treasure is only 0.018PPM, so you don't have to worry about harm to people. For bacteria, this concentration plus the attachment of negative ions is like drinking poison.

Negative ions can purify the air. As we all know, negative ions can make the floating dust invisible to the naked eye in the air at the micron level fall to the ground through the attraction and collision of positive and negative ions to form molecular clusters, but not only that, but also negative ions can reverse the duality of bacterial proteins, which can reduce or kill bacterial viability.

The sterilization ability of ozone should be improved by brain: ozone destroys the structure of microbial membrane by the oxidation of oxygen atoms to achieve sterilization. The inactivation reaction of ozone to bacteria is always very rapid. Unlike other bactericides, ozone can react with the double bond of bacterial cell wall lipids, penetrate into the cell, act on proteins and lipopolysaccharide, change the permeability of cells, and cause bacterial death. Ozone also acts on nuclear substances in cells, such as purine and pyrimidine in nucleic acids, to destroy DNA. Ozone first acts on the cell membrane, causing damage to the membrane components, leading to metabolic disorders. Ozone continues to penetrate the membrane, destroying the lipoproteins and lipopolysaccharide in the membrane, changing the permeability of cells, leading to cell dissolution and death.

As for the degradation of pesticide residues by ozone, the scientific community has also made experiments to prove that ozone has a strong degradation effect on methamidophos, omethoate, dichlorvos, parathion and deltamethrin. The degradation rate of methamidophos was the fastest, followed by deltamethrin, omethoate, dichlorvos and parathion. Among different kinds of vegetables, the pesticide residues in leafy vegetables are the most easily degraded, followed by bean and fruit vegetables. After 5 minutes of treatment, the results showed that ozone and fruit and vegetable cleaning agent had the same cleaning effect on pesticide residues in leafy vegetables, and the ozone cleaning effect on eggplant and fruit vegetables was better than that of fruit and vegetable cleaning agent—— The above content is compiled from Baidu Academic. No matter how good you say it, it's better to use it personally for a period of time to verify.

　　 Use and function of refrigerator treasure

It has been a week since I got the refrigerator treasure. After I got it, I quickly downloaded an app. The setting of the app is also relatively simple. First, I set the capacity of the refrigerator. The refrigerator of Xiaomojia has a capacity of 141 liters, which is still relatively large. I didn't find the model of Rongsheng refrigerator from the app, so I filled in the capacity manually.

If you stay in the cold storage for a while, you will see that the cold storage air is in a dangerous state. The red alert indicates that it is easy to make people sick, which may be exaggerated. But my refrigerator does have a strong taste. There are milk, red dates, eggs, various vegetables, and sometimes leftovers. There is always a strange smell.

An in-depth inspection was carried out, and after one day of use, the environment of the refrigerator has obviously improved from the APP, which has become to be improved. One day later, it will directly become a safe mode. At this time, you can smell the peculiar smell in the refrigerator. Boy, you can hardly smell any peculiar smell. Since this thing was put in the refrigerator, my mother has been telling me that the current product is really good. From the perspective of odor removal, the refrigerator treasure is very effective. In fact, according to the working principle introduced above, we can clearly realize that it must work. The refrigerator treasure is simply an ozone and negative ion generator, which kills and simulates the generation of bacteria in the refrigeration room by continuously releasing germicidal substances. If you also want to give your refrigerator a clean environment, you might as well buy one for a try. The price is not expensive, only 199 yuan, and the official guarantee can be used for 5 years! The price is very reasonable. It's not big. It's worth a lot to give 170g to relatives and friends.
