Referring to fig. 2 and 3, an air inlet 123 is formed in a side surface of the end cover 12, far from the motor body 1, a filter screen plate 124 with a plurality of filter holes is fixed on the air inlet 123, the filter screen plate 124 is used for preventing dust from entering the end cover 12 from the air inlet 123, an annular air outlet gap 122 is formed between the end cover 12 and the motor body 1, and the air outlet gap 122 is opposite to the plurality of cooling fins 131. When the rotation shaft 14 rotates to drive the cooling fan 141 to rotate, the air flows from the air inlet 123 side to the air outlet 122 side, and when the air with dust enters the air inlet 123, the dust is filtered by the filter screen 124, so as to reduce the dust content in the air blown out from the air outlet 122, thereby reducing the adhesion amount of the dust on the cooling fin 131 and reducing the influence of the dust on the heat dissipation of the motor.
Referring to fig. 3 and 4, a cleaning assembly 2 is disposed in the end cap 12, the cleaning assembly 2 is used for dredging the filter screen plate 124 again, and the cleaning assembly 2 includes a first driving member 3, a second driving member 4, a rotating rod 21, a fixed block 22 and a cleaning screen plate 23.

Referring to fig. 3 and 5, the rotating rod 21 is slidably connected to the fixed block 22 along the axis direction parallel to the rotating shaft 14, the first driving member 3 is used for driving the rotating rod 21 to slide on the fixed block 22, the rotating rod 21 is rotatably connected to the fixed block 22 along the axis direction parallel to the rotating shaft 14, and the second driving member 4 is used for controlling the rotation of the rotating rod 21 in the fixed block 22. The cleaning screen plate 23 is fixed to the end of the rotating rod 21 near the filter screen plate 124, and bristles 231 are fixed to the side surface of the cleaning screen plate 23 facing the filter screen plate 124. The cleaning screen plate 23 has good ventilation and is only used for cleaning the filter screen plate 124, and the air quantity blown onto the radiating fins 131 is not greatly influenced.
Referring to fig. 3 and 5, when the filter screen plate 124 is plugged by dust, the first driving member 3 drives the rotating rod 21 to move until the bristles 231 abut against the filter screen plate 124, and the second driving member 4 drives the rotating rod 21 to rotate. When the filter screen plate 124 filters dust normally, the first driving member 3 drives the rotation lever 21 to move to the cleaning screen plate 23 and the bristles 231 are far away from the filter screen plate 124, and the second driving member 4 controls the rotation lever 21 to stop rotating.
Referring to fig. 3 and 5, when the filter screen plate 124 is blocked by dust, the filter screen plate 124 is difficult to ventilate, which affects the heat dissipation efficiency of the motor, at this time, the first driving member 3 drives the rotating rod 21 to move to the bristles 231 to abut against the filter screen plate 124, and then the second driving member 4 drives the rotating rod 21 to rotate, so that the bristles 231 brush the filter screen plate 124, thereby cleaning the dust attached to the filter screen plate 124, enabling the filter screen plate 124 to recover the ventilation again, and recovering the heat dissipation efficiency of the motor. When the filter screen plate 124 filters dust normally, the cleaning screen plate 23 does not need to clean the filter screen plate 124, so the first driving member 3 drives the cleaning screen plate 23 and the bristles 231 away from the filter screen plate 124, and the second driving member 4 also controls the rotating rod 21 to stop rotating.
Referring to fig. 3 and 5, the first driving member 3 includes a rotating block 31, a spring 32, and a deformable elastic membrane 33, wherein the rotating block 31 is rotatably connected to the fixed block 22 in a direction parallel to the axis of the rotating shaft 14, and the rotating block 31 is collinear with the rotating circumferential direction of the rotating shaft 14. The rotating block 31 is provided with a rotating groove 311 towards the center of one side surface of the filter screen plate 124, one end of the rotating rod 21, which is far away from the cleaning screen plate 23, can be slidably connected in the rotating groove 311 along the axial direction parallel to the rotating shaft 14, a limiting block 211 is fixed on the outer wall of the rotating rod 21, a limiting groove 312 is provided in the rotating groove 311, and the limiting block 211 is slidably connected in the limiting groove 312 along the sliding direction parallel to the rotating rod 21. The spring 32 is located in the rotary groove 311, two ends of the spring 32 are fixedly connected to the bottom wall of the rotary groove 311 and one end face of the rotary rod 21, which is far away from the cleaning screen plate 23, respectively, and the spring 32 is always in a compressed state. When the motor stops running or the filter screen plate 124 is blocked by dust during normal operation, the spring 32 drives the rotating rod 21 to move towards one side of the filter screen plate 124 until the bristles 231 abut against the filter screen plate 124.
Referring to fig. 3 and 5, the filter screen plate 124 and the cleaning screen plate 23 are arranged in a spherical cover manner, the central axes of the filter screen plate 124 and the cleaning screen plate 23 are arranged in a collinear manner with the rotating shaft 14, the centers of the filter screen plate 124 and the cleaning screen plate 23 are arranged in a convex manner towards the side far away from the motor body 1, and the circulating direction of air in the filter holes on the cleaning screen plate 23 is towards the center side of the filter screen plate 124. The cleaning screen plate 23 has a recess 232 formed in a concave shape toward a side far away from the filter screen plate 124, the elastic membrane 33 is made of rubber or silica gel material, the circumferential outer wall of the elastic membrane 33 is fixed on the circumferential outer wall of the recess 232, and the elastic membrane 33 is disposed opposite to the center of the cleaning screen plate 23. Regardless of how the shaft 14 moves, a gap remains between the cleaning screen plate 23 and the filter screen plate 124. When the filter screen 124 filters dust normally, the elastic membrane 33 is used to receive the wind from the air inlet 123 passing through the filter screen 124 and entering the end cap 12, and the elastic membrane 33 drives the rotating rod 21 to move to the bristles 231 away from the filter screen 124 under the action of wind force.
Referring to fig. 3 and 5, when the screen plate 124 is blocked by dust, the ventilation of the screen plate 124 is deteriorated, and the wind force can not push the rotating rod 21 to move toward the side far from the screen plate 124 by acting on the elastic membrane 33, so the spring 32 can drive the rotating rod 21 to move toward the screen plate 124 until the bristles 231 abut against the screen plate 124 to clean the screen plate 124. When the filter screen 124 filters dust normally, the ventilation of the filter screen 124 is good, and wind force can act on the elastic membrane 33 to drive the cleaning screen 23 to move towards the side far away from the filter screen 124, so that the bristles 231 do not clean the filter screen 124 any more, and the bristles 231 do not extend into the filter holes of the filter screen 124 to affect the ventilation of the filter screen 124.
Referring to fig. 3 and 5, since the portion of the filter screen plate 124 facing the elastic membrane 33 is not cleaned by the bristles 231, the portion is blocked and then the effect of the air entering the end cap 12 on the elastic membrane 33 is deteriorated due to the blocking of the elastic membrane 33, and therefore, the shape of the filter screen plate 124 needs to be changed to allow the air to be concentrated toward the elastic membrane 33, so that the elastic membrane 33 can directly reflect the blocking condition of the filter screen plate 124.
Referring to fig. 4 and 5, the second driving member 4 includes a locking member 41 and a rotating member 42, and when the filter screen plate 124 filters dust normally, the locking member 41 controls the rotation of the rotating lever 21, and when the filter screen plate 124 is blocked by dust, the rotating member 42 drives the rotating lever 21 to rotate.
Referring to fig. 3 and 5, the locking member 41 includes a plurality of rotation limiting blocks 411, the rotation limiting blocks 411 are uniformly fixed on the circumferential outer wall of the rotating rod 21 along the circumferential direction of the rotating rod 21, and a side surface of the fixing block 22 facing the cleaning screen 23 is provided with a plurality of limiting grooves 222 matched with the rotation limiting blocks 411.
