The rear end cover 9 is connected with a dust cover 6 through a plurality of screws 7, and one end of the dust cover 6, which is far away from the motor body 1, is provided with a dust screen 8.
A driving assembly, a first swinging assembly, a second swinging assembly, a first brush assembly, a second brush assembly and a cooling assembly are arranged in the dust cover 6. The driving assembly is connected with the first swing assembly through a first connecting rod 21, and the driving assembly is connected with the second swing assembly through a second connecting rod. One end of the first swinging component, which is close to the dustproof net 8, is connected with the first brush component, and one end of the second swinging component, which is close to the dustproof net 8, is connected with the second brush component. The driving assembly drives the first swing assembly and the second swing assembly to swing simultaneously, so that the first brush assembly and the second brush assembly clean the dust screen 8, and dust is prevented from blocking the dust screen 8.
In the initial state, the first swing assembly and the second swing assembly are in a V shape, and dust is prevented from entering the motor body 1.
The first swinging assembly includes a first swinging plate 25, and a first strip-shaped hole 41 is formed on the first swinging plate 25.
The second swing assembly includes a second swing plate 24, and a second strip-shaped hole is formed in the second swing plate 24.

When the motor body 1 stops working and the driving assembly stops driving the first swinging plate 25 and the second swinging plate 24, the first magnetic strip 39 and the second magnetic strip 33 attract each other and are close to each other to be attached together, so as to drive the left end of the first swinging plate 25 and the left end of the second swinging plate 24 to be attached together, and the first swinging plate 25 and the second swinging plate 24 form a V shape due to the action of the 2 first fixing shafts 22, so that dust can be prevented from entering the motor body 1 through the heat dissipation net 14.
The driving assembly includes a drive bevel gear 12, a first driven bevel gear 26, a first rotating shaft 38, a first rotating disk 20, a second driven bevel gear 27, a second rotating shaft, and a second rotating disk 28.
The drive bevel gear 12 is fixedly mounted on the motor shaft 4. The drive bevel gear 12 is engaged with a first driven bevel gear 26 and a second driven bevel gear 27, respectively. The first driven bevel gear 26 and the second driven bevel gear 27 are symmetrically disposed at both sides of the drive bevel gear 12.
A first fixing rod 19 and a second fixing rod parallel to the first fixing rod 19 are fixedly installed in the dust cover 6. The first rotating shaft 38 is rotatably mounted on the first fixing rod 19 through a first bearing 37. One end of the first rotating shaft 38 is fixedly connected with the first driven bevel gear 26, and the other end of the first rotating shaft 38 is fixedly connected with the first rotating disk 20. The second rotating shaft is rotatably mounted on the second fixing rod through a second bearing, one end of the second rotating shaft is fixedly connected with the second driven bevel gear 27, and the other end of the second rotating shaft is fixedly connected with the second rotating disc 28.
As shown in fig. 10, the first rotating disk 20 is eccentrically provided with a first mounting shaft 36. One end of the first connecting rod 21 is hinged to the first mounting shaft 36, and the other end of the first connecting rod 21 is hinged to the right end of the first swing plate 25.
The second turntable 28 is eccentrically provided with a second mounting shaft. One end of the second connecting rod is hinged to the second mounting shaft, and the other end of the second connecting rod is hinged to the right end of the second swing plate 24.
The first and second mounting shafts 38 and 12 are symmetrically disposed about the drive bevel gear 12.
When the motor body 1 works, the motor shaft 4 drives the driving bevel gear 12 to rotate, and the driving bevel gear 12 drives the first driven bevel gear 26 and the second driven bevel gear 27 to simultaneously rotate, so as to drive the first rotating disc 20 and the second rotating disc 28 to simultaneously rotate, and further drive the first swinging plate 25 and the second swinging plate 24 to simultaneously swing.
When the second swing plate 24 swings, the second brush assembly is driven to clean the dust screen 8, and the second brush assembly acts on the cooling assembly through the extrusion piece, so that the cooling liquid circularly flows, and the heat dissipation effect is improved.
The cooling assembly comprises a first water bag 29, a second water bag 34 and a cooling pipeline 16. The first and second water bladders 29, 34 have elasticity and have the property of expanding and returning to their original shape after being pressed. When the liquid in the first and second water bags 29 and 34 is excessive, the bag expands and expands in volume.
The cooling duct 16 is laid on the casing 15 of the motor body 1. The water outlet of the cooling pipeline 16 is communicated with the first water bag 29 through the water outlet pipe 10, and the water inlet of the cooling pipeline 16 is communicated with the second water bag 34 through the water inlet pipe 11. A first check valve is arranged at the water outlet of the cooling pipeline 16. The first check valve allows the coolant to flow only from the cooling pipe 16 into the first water pocket 29. The water inlet of the cooling pipe 16 is provided with a second check valve which allows the coolant to flow only from the second water bladder 34 into the cooling pipe 16.
The first water pocket 29 is fixedly provided on the inner wall of the dust cover 6 above the first swing plate 25. The second water bladder 34 is fixedly provided on the inner wall of the dust cover 6 below the second swing plate 24. The first water bladder 29 and the second water bladder 34 are communicated through a connecting pipe 44. And a third check valve is arranged at the joint of the first water bag 29 and the connecting pipe 44. The third check valve allows the coolant to flow only from the first water bladder 29 into the second water bladder 34.
The first check valve, the second check valve and the third check valve are arranged so that the cooling liquid in the cooling assembly can only flow in one direction from the second water bag 34 into the cooling pipeline 16, from the cooling pipeline 16 into the first water bag 29 and from the first water bag 29 into the second water bag 34.
The extrusion comprises a pressure plate 23, a third connecting rod 43 and a limiting rod 35.
One end of the third connecting rod 43 is hinged to the lower end of the second swing plate 24 and is far away from the second magnetic strip 33. The other end of the third connecting rod 43 is hinged with the upper end of the pressure plate 23. When the first and second swing plates 25 and 24 are in a V shape, the second swing plate 24 keeps pressing the second water bag 34 through the pressing plate 23, so that the cooling pipe 16 is filled with the cooling liquid, and when the outside temperature is too high, the cooling liquid in the cooling pipe 16 can cool down and protect the motor body 1.
There are 4 gag lever posts 35, and the symmetric distribution is in the both sides of second water pocket 34, and every gag lever post 35 all is equipped with the slide. The pressing plate 23 is arranged above the second water bag 34, 4 limiting blocks are fixedly arranged on the pressing plate 23, and the 4 limiting blocks are respectively in limiting sliding fit with the corresponding slideways.
When the second swing plate 24 swings downward, the second swing plate 24 presses the pressing plate 23, the pressing plate 23 presses the second water bag 34, the second water bag 34 is pressed and compressed, the cooling liquid in the second water bag 34 enters the cooling pipe 16 through the water inlet pipe 11, and the cooling liquid in the cooling pipe 16 enters the first water bag 29 through the water outlet pipe 10. When the second swing plate 24 swings upward, the second swing plate 24 no longer presses the pressing plate 23, the second water bladder 34 is no longer pressed, the second water bladder 34 gradually recovers to its original shape, and the coolant in the second water bladder 34 becomes less, and the pressure in the first water bladder 29 is greater than the pressure in the second water bladder 34 because there is more coolant in the first water bladder 29. The cooling liquid in the first water pocket 29 is introduced into the second water pocket 34 through the connection pipe 44. When the second swinging plate 24 continuously swings up and down, the pressing plate 23 repeatedly acts on the second water bag 34, so that the cooling liquid circularly flows, and the heat dissipation effect is improved.
The motor shaft 4 is provided with a fan 13, and the fan 13 is positioned between the heat dissipation mesh 14 and the drive bevel gear 12. When the motor shaft 4 rotates, the fan 13 rotates. The fan 13 accelerates the air flow in the dust cover 6, so that the heat at the radiating net 14 can be radiated more quickly, and the radiating efficiency is improved. The fan 13 can also blow dust in the dust cover 6 out of the dust screen 8.
The outside of the motor body 1 is provided with the heat dissipation fins 2, so that the heat dissipation effect is further improved.
The motor body 1 is further provided with a base 5, so that the motor body 1 can be conveniently and fixedly installed.
A rotor 18 and a stator 17 are provided in the housing 15. The motor shaft 4 passes through the rotor 18, the stator 17 and the housing 15 to be fixedly connected.
The working principle is as follows: in an initial state, the motor body 1 does not work, the motor shaft 4 does not rotate, the fan 13 does not work, and the driving assembly does not act. Under the action of the first magnetic stripe 39 and the second magnetic stripe 33, the left ends of the first swinging plate 25 and the second swinging plate 24 are close to each other to form a V shape, so that dust is prevented from entering the motor body 1 through the heat dissipation net 14. Meanwhile, the second swing plate 24 keeps extruding the second water bag 34 through the pressure plate 23, so that the cooling pipeline 16 is filled with cooling liquid, and when the external temperature is too high, the cooling liquid in the cooling pipeline 16 can cool and protect the motor body 1.
When the motor body 1 is operated, the motor shaft 4 drives the fan 13 and the driving bevel gear 12 to rotate, the first driven bevel gear 26 and the second driven bevel gear 27 rotate simultaneously, but the rotation directions of the first driven bevel gear 26 and the second driven bevel gear 27 are opposite. The first and second swing plates 25, 24 swing at the same time. The first strip-shaped holes 41 on the first swinging plate 25 slide along their corresponding first fixed shafts 22, and the second strip-shaped holes on the second swinging plate 24 slide along their corresponding first fixed shafts 22.
As the left ends of the first and second swing plates 25, 24 are gradually brought closer to each other, the right ends of the first and second swing plates 25, 24 are gradually moved away from each other. As the left ends of the first and second swing plates 25, 24 are gradually moved away from each other, the right ends of the first and second swing plates 25, 24 are gradually moved closer to each other. The fan 13 blows air between the first and second swing plates 25 and 24, and when the opening between the right ends of the first and second swing plates 25 and 24 is larger than the left end, the wind speed gradually increases from right to left, so that dust falling onto the second magnetic stripe 33 from the first brush 30 is blown to the outside of the dust screen 8.
The first swinging plate 25 drives the first brush 30 to slide up and down in the chute 31, so as to clean the dust-proof net 8 and prevent dust from blocking the dust-proof net 8. The second swing plate 24 drives the second brush 32 to slide in the chute 31, so as to clean the dust-proof net 8, and prevent dust from blocking the dust-proof net 8.
Meanwhile, when the second swing plate 24 swings downwards, the second swing plate 24 presses the pressing plate 23, and the pressing plate 23 presses the second water bag 34, so that the cooling liquid in the second water bag 34 enters the cooling pipeline 16 through the water inlet pipe 11, and the cooling liquid in the cooling pipeline 16 enters the first water bag 29 through the water outlet pipe 10. When the second swing plate 24 swings upward, the second swing plate 24 no longer presses the pressing plate 23, the second water bladder 34 returns to its original shape, and the cooling liquid in the first water bladder 29 enters the second water bladder 34 through the connecting pipe 44. The second swinging plate 24 repeatedly acts on the second water pocket 34 through the pressing plate 23, thereby circulating the cooling liquid and increasing the heat radiation effect on the motor body 1.
When the motor body 1 stops working, under the action of the first magnetic strip 39 and the second magnetic strip 33, the left end of the first swinging plate 25 and the left end of the second swinging plate 24 are close to each other, the right end is opened, and the left end of the first swinging plate 25 and the second swinging plate 24 are in a V shape. The device reverts to the initial state.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
