The inclined through groove of the conical disc 21 is a slanted groove with a gradually decreasing width from outside to inside. The inner wall of the outer ring cover 22 is fixedly connected with elastic pads 25, which are evenly installed along the center of the outer ring cover 22. The width of the slanted groove changes from outside to inside, so that an air gap is formed between the slanted groove and the arc sliding block 24.

The end of the elastic pad 25 away from the outer ring cover 22 is fixedly connected with the arc sliding block 24. The outer side of the arc sliding block 24 is in sliding fit with the inclined through groove of the conical disc 21.

[0036] The third embodiment is based on the first and second embodiments, and please refer to Figures 6 to 7 The rear end cover 3 includes a rear cover cylinder 31 fixedly installed on the outer side of the cover shell 1 away from the front end cover 2. The inner wall of the rear cover cylinder 31 away from the cover shell 1 is fixedly connected with a through groove cover disc 35. The non-output end of the rotating shaft of the rotor 5 is clamped with the clamping shaft sleeve 32, so that the rotation of the rotor 5 drives the clamping shaft sleeve 32 to rotate, and the clamping shaft sleeve 32 drives the fan blade 36 to rotate along the axis of the rotating shaft through the fixed ring 37. The rotation of the fan blade 36 drives the air to enter the rear cover cylinder 31 from the outer side of the rear cover cylinder 31 and flow between the stator 4 and the rotor 5 under the drive of the fan blade 36, so as to absorb the heat generated by the motor. When the air enters the rear cover cylinder 31, the air enters the through groove cover disc 35. The outer side of the through groove cover disc 35 is uniformly provided with arc through grooves. The inner wall of the rear cover cylinder 31 close to the cover shell 1 is fixedly connected with a support ring 33. The inner wall of the support ring 33 is rotatably installed with the clamping shaft sleeve 32. The inner wall of the clamping shaft sleeve 32 is clamped with the non-output end of the rotating shaft of the rotor 5. The outer side of the clamping shaft sleeve 32 is fixedly installed with the fixed ring 37.

[0037] The outer side of the fixed ring 37 is fixedly installed with the fan blade 36. The fan blade 36 is evenly installed along the center of the fixed ring 37. The fan blade 36 is located between the support ring 33 and the through groove cover disc 35. The outer side of the rear cover cylinder 31 is uniformly provided with square grooves. The inner wall of the rear cover cylinder 31 is fixedly connected with a ring-shaped baffle 34. The square grooves are located between the ring-shaped baffle 34 and the through groove cover disc 35. The through groove cover disc 35 and the filter hole disc 38 are matched, so that the arc through grooves and the filter holes filter the air twice. The air is driven by the rotating fan blade 36 to rotate spirally. After the preliminary filtration through the arc through grooves, the spirally rotating air makes the dust particles in the air concentrated on the outer side in the rotating process under the action of the centrifugal force, and is blocked by the ring-shaped baffle 34. The inner wall of the ring-shaped baffle 34 is fixedly connected with the filter hole disc 38. The outer side of the filter hole disc 38 is uniformly provided with filter holes. The fan blade 36 is located between the filter hole disc 38 and the support ring 33.

[0038] In use, the motor is powered, the current flows in the winding of the stator 4, a magnetic field is generated around the winding of the stator 4, based on the principle of "minimum magnetic resistance", the magnetic flux always closes along the path with minimum magnetic resistance, thereby generating magnetic pull, and then forming the electromagnetic torque of the magnetic resistance, so that the rotor 5 rotates, and the mechanical energy converted from the electrical energy is output through the output end of the rotating shaft of the rotor 5, while in the process of rotating the rotor 5, the rear end cover 3 is driven to operate by the rotating shaft, the air flow is driven into the motor by the rear end cover 3, and is guided out by the front end cover 2, thereby taking away the heat inside the motor during operation, and achieving heat dissipation and cooling.

[0039] When the air is introduced into the rear end cover 3, the air enters the space between the inner filter disc 6 and the rear end cover 3, and under the driving of the air, the air passes through the through hole at the ring groove position of the inner filter disc 6, and at the same time, when passing through the through hole, the air first passes through the sponge plate 7, and the water in the air is absorbed by the water absorption property of the sponge plate 7, and after the air passes through the through hole of the inner filter disc 6, the air enters the space between the inclined ring plates 9 and continues to flow, and passes through the arc-shaped cover 10 through the air inlet groove of the arc-shaped cover 10, and enters the gap between the stator 4 and the rotor 5. Since the gap position is passed, the heat generated during the operation of the motor is absorbed and guided out by the front end cover 2, thereby achieving heat dissipation, and at the same time, when the air flows between the inclined ring plates 9, the width of the air flow path is gradually reduced by the inclination of the inclined ring plates 9, thereby increasing the flow rate of the air.

[0040] In the rear end cover 3, the rotating shaft non-output end of the rotor 5 is clamped by the clamping shaft sleeve 32, so that the rotation of the rotor 5 during operation drives the clamping shaft sleeve 32 to rotate, and the clamping shaft sleeve 32 drives the fan blade 36 to rotate along the axis center of the rotating shaft through the fixed ring 37. Through the rotation of the fan blade 36, the air enters the rear cover cylinder 31 from the outside of the rear cover cylinder 31, and flows between the stator 4 and the rotor 5 under the driving of the fan blade 36, thereby absorbing the heat generated during the operation of the motor. At the same time, when the air enters the rear cover cylinder 31, the air enters through the through groove cover disc 35, and the arc-shaped through groove and the filter hole cooperate to perform two filtering processes on the air through the cooperation of the through groove cover disc 35 and the filter hole disc 38. At the same time, the air is driven by the rotating fan blade 36, and the spiral rotation of the air after the preliminary filtering of the arc-shaped through groove causes the dust particles in the air to concentrate on the outside during the rotation according to the action of the centrifugal force, and cooperates with the annular baffle 34 to block the larger particles.

[0041] In the front end cover 2, the end of the cover 1 is closed by the cooperation of the conical surface disc 21 and the outer ring cover 22, and at the same time, in operation, air enters from the rear end cover 3 and flows towards the conical surface disc 21. When the air pressure inside the motor increases, the arc slider 24 in the inclined arc groove of the conical surface disc 21 is pushed by the air pressure, compressing the elastic pad 25 to deform, and at the same time, the width of the inclined arc groove changes from outside to inside, causing the gap between the inclined arc groove and the arc slider 24 to allow the air after absorbing heat to enter the outer ring cover 22, and then be discharged through the air outlet hole of the outer ring cover 22, achieving heat dissipation.
