Abstract
Description
Technical Field
[0001] This utility model belongs to the field of motor technology, and relates to a motor, and more particularly to a novel motor. Background Technology
[0002] An electric motor mainly consists of a stator and a rotor. The direction of motion of a current-carrying conductor in a magnetic field depends on the direction of the current and the direction of the magnetic field lines. The working principle of an electric motor is that the magnetic field exerts a force on the current, causing the motor to rotate.
[0003] Existing motors suffer from poor heat dissipation, and the external dust filter easily accumulates dust, further hindering heat dissipation and significantly increasing the failure rate. This shortens the motor's lifespan. Moreover, disassembly and cleaning often require tightening screws, making future maintenance inconvenient. Summary of the Invention
[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a new type of motor that is easy to assemble and disassemble.
[0005] The objective of this utility model can be achieved through the following technical solution: A novel motor, comprising a rotor, a stator, and a motor housing, wherein a front end cover and a rear end cover are respectively provided at the front and rear ends of the motor housing, characterized in that the rotor extends rearward to form a rear motor shaft, the rear end cover has a through hole for the rear motor shaft to pass through, a fan is provided on the rear motor shaft and relative to the rear end cover, the rear end cover has a plurality of heat dissipation holes, a filter dust cover for protecting the fan is provided on the rear end cover, a snap-fit device for connecting the filter dust cover is provided on the rear end cover, the rear end cover has a movable space for the snap-fit device to move, the snap-fit device consists of a snap-fit block and a return spring, and the filter dust cover has a snap-fit hole that cooperates with the snap-fit block.
[0006] In the aforementioned novel motor, a limiting part is provided on the snap-fit block.
[0007] In the aforementioned novel motor, both the front end cover and the rear end cover are bolted to the motor housing.
[0008] Compared with the prior art, the present invention provides a fan and heat dissipation holes at the rear end of the motor, which can accelerate the heat dissipation of the motor and prevent the motor from overheating and causing damage. The filter dust cover on the rear end cover can protect the fan and increase its lifespan. Furthermore, the snap-fit device on the rear end cover and the snap-fit block of the filter dust cover make installation and disassembly convenient, and make it easy to clean the filter dust cover after it becomes clogged.

[0011] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0012] like Figure 1 As shown, this novel motor includes a rotor 1, a stator 2, and a motor housing 3. A front end cover 4 and a rear end cover 5 are respectively provided at the front and rear ends of the motor housing 3. A rear motor shaft 6 extends rearward from the rotor 1. A through hole 7 is provided on the rear end cover 5 for the rear motor shaft 6 to pass through. A fan 8 is provided on the rear motor shaft 6 and relative to the rear end cover 5. Several heat dissipation holes 9 are provided on the rear end cover 5. A filter dust cover 10 is provided on the rear end cover 5 to protect the fan 8. A snap-fit device 12 is provided on the rear end cover 5 to connect the filter dust cover. The rear cover 5 has an active space 11 for the locking device 12 to move. The locking device 12 consists of a locking block 13 and a return spring 14. The filter dust cover has a locking hole 15 that cooperates with the locking block 13. When connecting, the locking block 13 is pressed to make the locking block enter the active space 11. Then the filter dust cover 10 is installed on the rear cover 5. When the locking hole 15 is exactly above the locking block 13, the locking block 13 loses its restraint and automatically returns to its original position under the action of the return spring 14 to lock with the locking hole 15.
[0013] To elaborate further, a limiting part 16 is provided on the card block 13.
[0014] To elaborate further, both the front cover 4 and the rear cover 5 are bolted to the motor housing 3.
[0015] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
[0016] Although this document frequently uses terms such as rotor 1, stator 2, motor housing 3, front cover 4, rear cover 5, rear motor shaft 6, through hole 7, fan 8, heat dissipation hole 9, filter dust cover 10, moving space 11, snap-fit device 12, snap-fit block 13, return spring 14, snap-fit hole 15, and limiting part 16, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
