Description

Technical Field

[0001] The present application belongs to the field of motor technology, and specifically relates to a dust-proof motor. Background Art

[0002] A motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. Motors provide power sources for many mechanical structures in daily life and occupy a very important position.

[0003] The motor will be affected by the external environment during operation, especially dust or particles in the outside will enter the interior of the motor. In the absence of protective measures, the motor will be damaged due to the accumulation of dust.

[0004] At present, when the motor is in use, there is a lack of dust treatment structure for the outer wall of the motor and the output shaft. Currently, most of them are dust-proofed by filtering nets, which reduces the dust removal effect. Therefore, it is necessary to propose a dust-proof motor to solve the above-mentioned problems. Summary of the invention

[0005] The purpose of this application is to make up for the shortcomings of the prior art and provide a dust-proof motor that can blow off the dust that falls on the outer wall of the motor and the output shaft, while achieving a comprehensive dust removal effect, avoiding dust accumulation from affecting the operation of the output shaft, thereby improving the dust removal efficiency.

[0006] This application provides the following technical solutions:

[0007] A dustproof motor comprises a motor, wherein the output end of the motor is fixedly connected to an output shaft, a fixing ring is sleeved on the outer wall of the motor, a dustproof cavity is installed inside the fixing ring, a plurality of air outlets distributed in a ring are opened on the left side of the dustproof cavity, a fan is connected to the right side of the dustproof cavity, and two cylinders with output ends fixedly connected to the dustproof cavity are installed on the right side of the fixing ring.

[0008] In order to achieve dust-proof effect for the motor, as a preferred dust-proof motor of the present application, three arc plates are arranged inside the fixing ring, and two elastic members are installed between the outer walls of the three arc plates and the inner wall of the fixing ring.

[0009] In order to enable the fixing ring to move smoothly on the outer wall of the motor, as a preferred dustproof motor of the present application, three balls are embedded in the inner walls of the three arc-shaped plates.

[0010] In order to enable the dustproof cavity to be smoothly moved out of the fixing ring, as a preferred dustproof motor of the present application, an opening is provided on the left side of the fixing ring.

[0011] In order to work with the fixing ring held in hand, as a preferred dustproof motor of the present application, the upper end surface of the fixing ring is fixedly connected with a vertical rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The present application first enables the cylinder to push the dustproof chamber out of the fixed ring and enables the fan to work, blowing air to the output shaft of the motor through multiple air outlets, thereby blowing off the dust that has fallen on the outer wall of the motor and the output shaft. At the same time, the cylinder pushes the dustproof chamber to move left and right, thereby achieving a comprehensive dust removal effect, preventing dust accumulation from affecting the operation of the output shaft, and thus improving the dust removal efficiency.
