Intelligent trash can is composed of advanced microcomputer control chip, infrared induction detection device and mechanical transmission part. It is a high-tech new product integrating machinery and photoelectricity. When a person's hand or an object is close to the throwing opening (sensing window) for about 25 cm-35 cm, the lid of the trash can will automatically open, and the lid will automatically close after the garbage is thrown for 3-4 seconds, so that people and objects do not need to touch the trash can, which can completely solve the health infection hidden danger of the traditional trash can to users.
Second, the working principle of smart trash can
Intelligent induction trash can is relative to ordinary trash can. In short, the cover can be opened and closed by the sensor, without manual and foot stepping. Compared with ordinary trash can, it has an electronic part and a mechanical drive part. The electronic part is controlled by an ic, the price of which is less than two yuan, plus an inductor. At present, the price of the best imported inductor in this field is less than five yuan. The mechanical driving part is simpler, just driving the cover to open and close.
The principle of induction trash can is the same as that of induction door. Only when people come into contact with the infrared rays emitted by the trash can and other parts of the body will the lid of the trash can automatically open and close, so that we can avoid touching the trash can and stay away from the bacteria in the trash can.
At present, there are three induction methods in the market: pyroelectric infrared, infrared tube alignment and microwave induction. These technologies are mainly developed by Zhejiang Xingfa Plastic Industry in cooperation with a number of professional research institutions. The barrel body is made of stainless steel imported from the United States, with high purity, which is incomparable to ordinary domestic cold-rolled iron. Using infrared automatic sensing function, the sensing height of zinc-free circuit boards in the United States is {30-40CM}. After the lid is opened, the lid will not be closed again until the things in the sensing area leave, which not only improves the sensing height {15-20CM} in the market, but also improves the shortcomings of automatic sensing in the market that there is no delay and it is easy to be caught. Zinc-free is an environmental protection concept advocated by the state, and it is applied to garbage cans, which embodies the concept of energy saving and environmental protection.
The induction trash can applies advanced technologies such as microcomputer control, infrared induction and mechatronics to the trash can field, which makes the trash can electrified and automated, and has the characteristics of stable performance, long service life (design life is 6- 10 year), convenient use, accurate operation, accurate design, sanitation and environmental protection, energy saving and low consumption (power consumption is13 of similar products in the market).
