[0075] In this embodiment, the connecting column 173 and the brush roller body 171 are interference fit. Specifically, a plug connector 171a is provided at the end of the brush roller body 171, and a plug hole 173a is opened at the end of the connecting column 173. The plug connector 171a is interference fit in the plug hole 173a.

[0076] In this embodiment, the outer circumferential surface of the connecting column 173 is provided with a stop ring 175, which is accommodated in the driving box 190 and is used to abut against the edge of the clearance hole 193 to prevent the connecting column 173 from slipping out of the clearance hole 193. Specifically, a clearance groove for accommodating the connecting column 173 is also provided on the box cover 197, so that one end of the connecting column 173 is accommodated in the clearance hole 193 and the other end is accommodated in the clearance groove, and the connecting column 173 is limited from both ends, ensuring the driving stability of the connecting column 173, thereby making the movement of the brush roller body 171 more stable. In addition, the connecting column 173 is assembled in the driving box 190 and is prevented from slipping off by the stop ring 175. When replacing the brush roller body 171, it is not necessary to remove the connecting column 173, which simplifies the disassembly and assembly process. At the same time, the connecting column 173 can be reused, saving materials.

[0077] In summary, the present embodiment provides a self-cleaning drive mechanism 100, and its driving process is as follows: when cleaning is performed again, the drive motor 133 is started, and the drive motor 133 drives the drive gear 131 to rotate, thereby driving the transmission rack 151 to move upward along the limiting groove 191. Under the limiting action of the inclined guide hole 155 and the air-avoiding groove 117, the cleaning brush roller 170 first moves upward and disengages from the brush roller accommodating groove 118. The cleaning brush roller 170 enters the guide groove 115 from the air-avoiding groove 117. As the transmission rack 151 continues to move, the cleaning brush roller 170 moves upward. 170 moves upward along the guide groove 115 and fits against the inner surface of the bottom shell 111 to clean the air duct 119. When the cleaning brush roller 170 moves to the top limit position of the guide groove 115, the driving motor 133 is stopped. Since the gap between the wind wheel and the bottom shell 111 is narrowed here, the cleaning brush roller 170 can contact the wind wheel. At this time, the wind wheel is started slowly to clean the wind wheel. After the cleaning is completed, the driving motor 133 is started in reverse, thereby driving the cleaning brush roller 170 to return to the brush roller accommodating groove 118 along the original path to complete the cleaning. The self-cleaning drive mechanism 100 provided in this embodiment makes the movement process of the cleaning brush roller 170 more stable by setting multiple limit structures, thereby ensuring the driving stability of the cleaning brush roller 170 and improving the cleaning effect.
