Of course, in other embodiments of the present invention, the bristle area of the cleaning brush 22 may also be smaller than or equal to the net surface area of the air duct net 101, which may be specifically selected according to actual needs, and is not specifically limited herein.
Wherein, the driving assembly 21 is connected with the cleaning brush 22, and the driving assembly 21 is used for converting the rotary motion into the linear motion so as to drive the cleaning brush 22 to slide back and forth. As an embodiment, the driving assembly 21 includes a driving motor 211 and a screw rod 212, the driving motor 211 is connected to the controller, the screw rod 212 is connected to a rotating shaft of the driving motor 211, the screw rod 212 penetrates through the cleaning brush 22 and has two ends respectively fixedly connected to the trash can 100, and the driving motor 211 drives the screw rod 212 to perform a rotating motion, so as to drive the cleaning brush 22 to slide back and forth on the sliding rod 23. For example, when the controller controls the driving motor 211 to rotate forward, the cleaning brush 22 is driven to slide rightward, and then the controller controls the driving motor 211 to rotate backward to drive the cleaning brush 22 to slide leftward, and the cleaning brush 22 slides leftward and rightward once to complete one working cycle. Of course, in other embodiments, the driving motor 211 may rotate in the reverse direction to drive the cleaning brush 22 to slide in the right direction, and the driving motor 211 may rotate in the forward direction to drive the cleaning brush 22 to slide in the left direction. It is understood that the driving motor 211 may be a stepping motor or a servo motor, and a servo motor is preferably used to improve the accuracy. In addition, the driving motor 211 may be directly installed on the inner wall of the garbage can 100, or may be installed on the inner wall of the garbage can 100 through a mounting seat. In addition, a nut is arranged on the cleaning brush 22, the screw rod 212 penetrates through the nut, and the nut is matched with the screw rod 212 to convert the rotary motion into the linear motion.
In addition, as is preferable, both ends about slide bar 23 are provided with limit switch 24, limit switch 24 with the controller links to each other, cleaning brush 22 slides from side to side and touches limit switch 24, limit switch 24 passes the signal to the controller, the controller control driving motor 211 opens and shuts. The movement position of the cleaning brush 22 is detected by the limit switch 24, and then the movement position is fed back to the controller, so that the accurate control of the position of the cleaning brush 22 is realized, and the cleaning effect is further improved. It is understood that both ends of the sliding rod 23 and the lead screw 212 are provided with limit switches 24.
The cleaning brush 22 slides left and right once respectively to form a working cycle, that is, the cleaning brush 22 cleans the air duct net 101 right once and cleans the air duct net 101 left once, until the air duct pressure value in the air outlet 102 detected by the pressure sensor 1 reaches a preset value, the air duct net 101 is no longer blocked, the controller controls the driving motor 211 to stop working, that is, the automatic cleaning action is completed, otherwise, the controller controls the air duct net to enter the next working cycle.
