Further, the cleaning part 210 includes a mop and/or a floor brush.
The gear assembly 130 includes a first bevel gear 132, a second bevel gear 134, and an output shaft 136. The first bevel gear 132 is connected to the driving member 120, the first bevel gear 132 is meshed with the second bevel gear 134, the one-way gear portion 150 is meshed with the second bevel gear 134, the output shaft 136 is connected to the second bevel gear 134, and the output shaft 136 is used to connect the cleaning portion 210.
The lifting mechanism 100 lowers the cleaning part 210 to clean the floor using the cleaning part 210. Specifically, the driving member 120 drives the first bevel gear 132 to rotate, the first bevel gear 132 rotates to drive the second bevel gear 134 to rotate, and the first bevel gear 132 has a downward component force on the second bevel gear 134. The second helical gear 134 can drive the unidirectional gear portion 150 to idle. The second bevel gear 134 moves downward by the downward component force of the first bevel gear 132, so that the cleaning part 210 descends from the top position to the bottom position, and then the cleaning part 210 can clean the ground.
After the cleaning portion 210 is cleaned, the lifting mechanism 100 lifts the cleaning portion 210 to collect the cleaning portion 210. Specifically, the driving member 120 drives the first bevel gear 132 to rotate reversely, the first bevel gear 132 drives the second bevel gear 134 to rotate reversely, the first bevel gear 132 has an upward component force on the second bevel gear 134, and the second bevel gear 134 drives the unidirectional gear portion 150 to rotate reversely. The first bevel gear 132 and the second bevel gear 134 need to overcome a certain torque, there is an upward component, and the unidirectional gear portion 150 has a resistance torque to the second bevel gear 134, there is an upward component. Accordingly, the second bevel gear 134 moves upward by the two upward component forces from the bottom position to the top position to complete the lifting action of the cleaning portion 210.
It will be appreciated that the first portion of the output shaft 136 is located in the housing 110, the second portion of the output shaft 136 extends out of the housing 110, the second portion of the output shaft 136 is connected to the cleaning portion 210, and the second bevel gear 134 can move to drive the output shaft 136 to move, so as to achieve the function of lifting the cleaning portion 210. Meanwhile, the second bevel gear 134 rotates to drive the cleaning part 210 to rotate, and when the cleaning part 210 is at the bottom position, the output shaft 136 rotates to drive the cleaning part 210 to rotate for cleaning.
