Disassembly mechanisms 5 are fixedly connected to both the left and right sides of the outer surface of the end cover body 4. The end cover body 4 and the first connecting ears 3 are detachably connected through the disassembly mechanisms 5. The disassembly mechanism 5 includes a second connecting ear 501, an insertion block 502, an inner groove 503, a moving block 504, a push rod 505, and an insertion rod 506. A cooling mechanism 6 is provided in the inner cavity of the end cover body 4. The cooling mechanism 6 includes a fan blade 601, a water pipe 602, and a ventilation opening 603. The second connecting ear 501 is fixedly connected to the outside of the end cover body 4. The insertion block 502 is fixedly connected to the back side of the second connecting ear 501. The number of inner grooves 503 is two, which are respectively opened on the upper and lower sides of the inner surface of the first connecting ear 3. The number of moving blocks 504 is two, which are respectively slidably connected to the inner sides of the two inner grooves 503. The number of push rods 505 is two, which are respectively fixedly connected to the outside of the two moving blocks 504. The number of insertion rods 506 is two, which are respectively fixedly connected to the front sides of the two moving blocks 504. The fan blade 601 is fixedly connected to the outer surface of the rotating shaft 2, and the fan blade 601 is located in the inner cavity of the end cover body 4. The water pipe 602 is arranged in the inner cavity of the end cover body 4 and on the back side of the fan blade 601. The inner end interface and the outer end interface of the water pipe 602 respectively penetrate through the upper left and lower right of the end cover body 4 and extend to the outside. The number of ventilation openings 603 is four, which are respectively opened around the front side of the end cover body 4.

[0030] By setting up the disassembly mechanism 5, it is convenient to disassemble and install between the end cover body 4 and the motor body 1, avoiding the traditional bolt connection method. This not only facilitates the maintenance and repair of the motor body 1 but also prevents the bolts from rusting, which may affect the maintenance work of the motor body 1. By setting up the cooling mechanism 6, it can play a role in cooling the motor body 1 and the rotating shaft 2, preventing a large amount of heat from being generated after the motor body 1 and the rotating shaft 2 work for a long time, which may affect the service life of the motor body 1 and the rotating shaft 2.

[0031] Embodiment 2

[0032] In one embodiment, slots 7 are respectively opened on the front sides of the first connecting ears 3, and the insertion blocks 502 are inserted into the inner sides of the slots 7. Circular grooves 8 are respectively opened on the upper and lower sides of the insertion blocks 502, and the insertion rods 506 respectively penetrate through the inner surfaces of the first connecting ears 3 and are inserted into the inner sides of the circular grooves 8. Pressure springs 9 are respectively arranged on the inner sides of the inner grooves 503, and the two ends of the pressure springs 9 are respectively fixedly connected to the outer sides of the inner grooves 503 and the outer sides of the moving blocks 504. Limit grooves 10 are respectively opened on the upper and lower sides of the outer sides of the first connecting ears 3, and the push rods 505 penetrate through the inner sides of the limit grooves 10 and extend to the outside. A filter screen 11 is fixedly connected to the front side of the inner cavity of the end cover body 4, and the filter screen 11 is made of fiberglass.

[0033] By setting up the slots 7, the preliminary connection between the second connecting ear 501 and the end cover body 4 can be completed by inserting the insertion blocks 502 into the inner sides of the slots 7. By setting up the circular grooves 8, the connection between the insertion blocks 502 and the insertion rods 506 can be completed by inserting the insertion rods 506 into the inner sides of the circular grooves 8, forming a cross-shaped fixation with the second connecting ear 501 and the end cover body 4, further improving the stability during connection. By setting up the pressure springs 9, when the moving blocks 504 move, it can drive the deformation of the pressure springs 9 to generate pressure. By setting up the limit grooves 10, it can play a role in limiting the movement of the push rods 505. By setting up the filter screen 11, it can play a filtering role to prevent external dust from entering the inner cavities of the end cover body 4 and the motor body 1. And the fiberglass material is a high-temperature resistant material, which can further improve the service life of the filter screen 11.

[0034] When the utility model is working: First, when the motor body 1 and the end cover body 4 are working properly, the output end of the motor body 1 drives the rotating shaft 2 to rotate, and the rotating shaft 2 drives the fan blade 601 to rotate, which can discharge a large amount of heat generated during the operation of the motor body 1. And by setting the water pipe 602, the coolant can be poured into the inside of the water pipe 602 to further improve the cooling effect. When the motor body 1 is damaged and the end cover body 4 needs to be disassembled, the push rods 505 on the left and right sides can be pulled outward simultaneously. The push rods 505 drive the moving blocks 504 and the insertion rods 506 to move outward simultaneously, so that the insertion rods 506 are disengaged from the inside of the circular groove 8, releasing the limit on the circular groove 8. And at this time, the compression spring 9 deforms due to the extrusion of the moving block 504. At this time, the second connecting ear 501 can be pulled, so that the second connecting ear 501 drives the insertion block 502 to move forward, and the insertion block 502 is disengaged from the inside of the insertion slot 7, and the disassembly of the end cover body 4 can be completed. When the end cover body 4 needs to be installed again, the push rod 505 is still pulled. The push rod 505 drives the moving block 504 to squeeze the compression spring 9. After the insertion block 502 is inserted into the inside of the insertion slot 7, the push rod 505 is released, and the compression spring 9 will rebound to its original state and push the moving block 504 and the insertion rod 506 until the insertion rod 506 is inserted into the inside of the circular groove 8, and the rapid installation of the end cover body 4 can be completed.

[0035] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
