Referring to fig. 5 and 6, the side plate 133 is provided with a guide groove 135 extending along the edge of the bottom case 131, the extending direction of the guide groove 135 is parallel to or has the same radian as the extending direction of the limiting sliding groove 171, the driving outer box 170 is arranged on the side plate 133, and the end of the cleaning brush rod 110 penetrates through the guide groove 135 and is connected with the driving inner box 153 for moving along the extending direction of the guide groove 135 under the driving of the driving inner box 153. Through seting up guide way 135 on curb plate 133, box 153 drives in the drive and cleans brush-holder stud 110 and moves along guide way 135, has realized the direction and spacing to cleaning brush-holder stud 110, has further guaranteed the stability of cleaning brush-holder stud 110 motion.

In this embodiment, the guide groove 135 has an arc shape, and the arc shape is the same as the arc shape of the limiting sliding groove 171. In other preferred embodiments of the present invention, when the limiting sliding groove 171 is linear, the guiding groove 135 is also linear and parallel to the limiting sliding groove 171.

In this embodiment, bottom shell 131 is further provided with an accommodating groove 139 for accommodating cleaning brush rod 110, two ends of accommodating groove 139 respectively extend to two side plates 133, side plates 133 are further provided with an avoiding groove 137 communicated with guide groove 135, avoiding groove 137 and accommodating groove 139 are arranged oppositely, and driving assembly 150 is further configured to drive cleaning brush rod 110 to move along avoiding groove 137, so that cleaning brush rod 110 enters or leaves accommodating groove 139. By forming the receiving groove 139 on the bottom case 131, the cleaning brush bar 110 can be received in the receiving groove 139 when not being cleaned, so that the cleaning brush bar 110 is prevented from staying in the air duct 190 and affecting the air flow direction in the air duct 190.

In this embodiment, the width of the avoiding groove 137 is the same as the width of the guide groove 135, and the cleaning brush bar 110 can slide from the guide groove 135 to the avoiding groove 137 and also slide from the avoiding groove 137 to the guide groove 135 by the driving of the driving inner case 153, thereby achieving the function of the cleaning brush bar 110 entering or leaving the housing groove 139.

In this embodiment, the driving inner case 153 further has an inclined guide hole 153f, and the end of the cleaning brush rod 110 is slidably inserted into the inclined guide hole 153f and is driven by the driving assembly 150 to slide along the inclined guide hole 153f, so that the cleaning brush rod 110 moves along the avoiding groove 137. Through set up slope guiding hole 153f in box 153 in the drive, can make box 153 can drive under the drive of driving piece 151 and clean brush-holder stud 110 and get into or leave holding tank 139 in the drive, avoided additionally to set up actuating mechanism and realize this function, simplified structure.

In this embodiment, the extension direction of the inclined guide hole 153f is set at an acute angle to the movement direction of the driving inner case 153, and the inclined direction of the inclined guide hole 153f is opposite to the inclined direction of the escape groove 137 and opposite to the movement direction of the cleaning brush bar 110 when it leaves the housing groove 139. Specifically, when the cleaning brush bar 110 leaves the receiving groove 139, under the abutting action of the lower side edge of the inclined guiding hole 153f, the cleaning brush bar 110 receives the opposing upward abutting force, and the cleaning brush bar 110 can be driven to move upward, and meanwhile, because the inclined guiding hole 153f is obliquely arranged, in the process of driving the cleaning brush bar 110 to move upward, the cleaning brush bar 110 moves along the avoiding groove 137, and thus leaves the receiving groove 139. When the cleaning brush bar 110 enters the receiving groove 139, the cleaning brush bar 110 receives downward gravity or abutting force under the abutting action or gravity action of the upper side edge of the inclined guide hole 153f, and meanwhile, due to the inclined arrangement of the inclined guide hole 153f, the cleaning brush bar 110 can move along the avoiding groove 137 while moving downward, so as to enter the receiving groove 139.

In summary, in the driving process of the air duct self-cleaning mechanism 100 provided in this embodiment, when cleaning is required, the driving motor 151b is started, the driving gear 151a is driven by the driving motor 151b to rotate, the driving inner box 153 is driven to slide along the limiting sliding groove 171 under the meshing action of the driving gear 151a and the transmission rack 181, and meanwhile, the driving inner box 153 drives the cleaning brush rod 110 to move along the avoiding groove 137 through the inclined guide hole 153f, so as to drive the cleaning brush rod 110 to leave the accommodating groove 139. After leaving the receiving groove 139, the driving inner case 153 continues to drive the sweeping brush bar 110 to move upward along the guiding groove 135, so as to clean the air duct 190. When the cleaning brush rod 110 moves to the upward limit position, the driving motor 151b is stopped, the cleaning brush rod 110 can contact with the wind wheel due to the narrow cleaning gap, and the wind wheel is started slowly at the moment, so that the cleaning of the wind wheel can be realized. After the wind wheel is cleaned, the driving element 151 is reversely started to drive the cleaning brush rod 110 to move downwards along the guide groove 135, and the cleaning brush rod 110 is driven to move along the avoiding groove 137 under the action of the inclined guide hole 153f and is accommodated in the accommodating groove 139 again to complete the cleaning work. The air duct self-cleaning mechanism 100 provided by the embodiment is stable in driving, can automatically clean the air duct 190 and the wind wheel, and is good in cleaning effect.
