1. Electric buttons: There are several buttons on the general trash can. When you press one of them, the lid of the trash can will be opened electrically. Put the trash into the trash can, and the lid will automatically close after a few seconds. The disadvantage of this type of trash can is that it actually has to be touched by hand. It is not like the traditional method of using manpower to force the lid of the barrel to be opened by the torque of mechanical equipment, but to open the lid of the barrel by pressing the torque of the mechanical device by hand.
2. Infrared sensor flip cover: This kind of sensor trash can generally does not need to be touched, which is well guaranteed in terms of environmental hygiene. Generally, an infrared sensor is installed on the top of the trash can. People can swing their arms or stay on the trash can for a period of time to input the data signals collected by the sensor into the CPU, and then the mechanical system will reply and open the lid. Throw it into the trash again, and it will automatically turn off after a few seconds.
3. Side-pull smart trash can with infrared sensor. This side-pull type open-lid trash can avoids the problem of overlapping and covering the clamshell area, but its magnetic induction sensitivity is not high, the response time is slow, and it cannot guarantee sufficient convenience and speed.
