Description

Technical Field

[0001] This utility model belongs to the field of motor technology, and relates to a motor housing, and particularly to a motor housing that is easy to clean. Background Technology

[0002] Electric motors are widely used drive devices, and in industrial production, they are crucial for ensuring the normal operation of the production line where the driven equipment is located. An electric motor generally consists of a motor housing and front and rear covers at both ends. Inside the housing is the motor body (including the stator, rotor, and other components). A fan, rotating coaxially with the motor, is mounted on the outside of the rear cover to dissipate heat. Existing rear covers are made of 1.9mm thick sheet metal, making replacement difficult if damaged. Furthermore, the fan, located outside the rear cover and rotating with the motor shaft, accumulates dust on the fan blades and dust cover over time, affecting fan operation and resulting in poor internal heat dissipation. Additionally, existing dust covers and rear covers are often bolted together, making cleaning the dust cover and replacing the fan inconvenient. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the prior art by providing an easy-to-clean motor housing.

[0004] The objective of this utility model can be achieved through the following technical solution: a motor housing that is easy to clean, comprising a motor outer shell, wherein a motor shaft is disposed inside the motor outer shell, characterized in that the motor outer shell comprises a motor housing body, a front end cover and a rear end cover, one end of the motor shaft passes through the rear end cover and is connected to a cooling fan for heat dissipation, one end of the rear end cover is provided with a detachable dust cover for protecting the cooling fan, the rear end cover is provided with a connecting part for connecting the dust cover, the inner wall of the connecting part is provided with a snap-fit ​​mechanism, the connecting part is provided with an installation space for installing the snap-fit ​​mechanism, the snap-fit ​​mechanism comprises a snap-fit ​​block and a snap-fit ​​spring, the dust cover is provided with a snap-fit ​​groove that cooperates with the snap-fit ​​block, and an unlocking element is provided between the connecting part and the dust cover.

[0005] In the aforementioned easy-to-clean motor housing, the unlocking component is provided with a limiting part, and the inner wall of the connecting part is provided with a guide groove for the limiting part to move.

[0006] In the aforementioned easy-to-clean motor housing, the snap-fit ​​block is provided with an inclined portion.

[0007] Compared with the prior art, this utility model can realize the quick assembly and disassembly of the dust cover and the rear end cover through the cooperation of the snap-fit ​​mechanism, the unlocking part and the snap-fit ​​groove, making it more convenient to clean the dust cover and clean or replace the fan later, reducing the accumulation of dust on the dust cover and the fan, and further improving the heat dissipation performance.

[0011] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0012] like Figure 1 As shown, the motor housing of this cleaning device includes a motor outer shell 1, a motor shaft 2 is disposed inside the motor outer shell 1, the motor outer shell 1 includes a motor housing body 3, a front end cover 4 and a rear end cover 5, one end of the motor shaft 2 passes through the rear end cover 5 and is connected to a cooling fan 6 for heat dissipation, one end of the rear end cover 5 is provided with a removable dust cover 7 for protecting the cooling fan 6, the rear end cover 5 is provided with a connecting part 8 for connecting the dust cover 7, the inner wall of the connecting part 8 is provided with a snap-fit ​​mechanism 9, the connecting part 8 is provided with an installation space 10 for installing the snap-fit ​​mechanism 9, the snap-fit ​​mechanism 9 includes a snap-fit ​​block 11 and a snap-fit ​​spring 12, the dust cover 7 is provided with a snap-fit ​​groove 13 that cooperates with the snap-fit ​​block 11, and an unlocking element 14 is provided between the connecting part 8 and the dust cover 7.

[0013] To elaborate further, the unlocking component 14 is provided with a limiting part 15, and the inner wall of the connecting part 8 is provided with a guide groove 16 for the limiting part 15 to move.

[0014] To elaborate further, the latching block 11 is provided with an inclined portion 17, which allows the unlocking component 14 to easily press the latching block 11 into the installation space 10.

[0015] During disassembly, the unlocking piece 14 is used to press the snap-fit ​​block 11 into the installation space 10, so that the snap-fit ​​block 11 is away from the snap-fit ​​groove 13, thereby causing the snap-fit ​​mechanism 9 to lose its constraint on the dust cover 7. Then, the dust cover 7 and the unlocking piece 14 are taken out together to complete the disassembly. During installation, simply insert the dust cover 7 into the connecting part 8. The snap-fit ​​block 11 can be easily pressed into the installation space 10 through the inclined part 17 of the snap-fit ​​block 11. After the dust cover 7 passes through and is exactly equivalent to the snap-fit ​​groove 13 being located at the snap-fit ​​block 11, the snap-fit ​​block 11 loses its constraint and automatically resets under the force of the snap-fit ​​spring 12 to lock the dust cover 7, making disassembly and assembly more convenient.

[0016] 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 substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0017] Although this document frequently uses terms such as motor housing 1, motor shaft 2, motor housing body 3, front cover 4, rear cover 5, cooling fan 6, dust cover 7, connecting part 8, snap-fit ​​mechanism 9, installation space 10, snap-fit ​​block 11, snap-fit ​​spring 12, snap-fit ​​groove 13, unlocking part 14, limiting part 15, guide groove 16, and inclined part 17, 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.
