Description

Technical Field

[0001] The present invention relates to the field of motor cleaning equipment, and particularly to a motor grinding brush. Background Art

[0002] During the long-term use of a motor, a large amount of dust, dirt, and some metal debris and other impurities will accumulate inside and on the surface of the motor. These impurities will affect the heat dissipation performance of the motor, increase the frictional resistance during the operation of the motor, and may even cause motor failures and shorten the service life of the motor. Currently, for the cleaning of motors, the commonly used tools are ordinary brushes or simple cleaning brushes, and these tools have some obvious deficiencies. The hardness and length of the bristles of an ordinary brush are difficult to adjust according to the cleaning requirements of different parts of the motor, the cleaning effect is not good, and when cleaning some narrow or complex parts, it is difficult to clean deeply. The simple cleaning brush has a single structure, cannot effectively remove stubborn dirt and metal debris, and is likely to damage the components of the motor during the cleaning process. At the same time, the existing cleaning tools are not convenient for collecting and processing the debris ground and cleaned, resulting in a messy cleaning site. Therefore, a grinding brush that can efficiently clean the motor, is convenient to operate, and can effectively collect debris is needed. Summary of the Invention

[0003] In view of the above problems, the present invention provides a motor grinding brush. By setting an adjustable bristle structure and a debris collection device, the cleaning effect of the motor can be effectively improved, it is convenient for the operator to use, and at the same time, the cleaning site can be kept clean.

[0005] A motor grinding brush includes a brush body. One end of the brush body is provided with a connection part for connecting a driving device. The brush body includes an outer layer of bristles and an inner layer of bristles. The outer layer of bristles is fixedly arranged on the outer surface of the brush body, and the inner layer of bristles is arranged inside the brush body through an adjustable mechanism;

[0006] The adjustable mechanism includes a fixed rod, an adjusting screw rod, and a slider. The fixed rod is fixedly arranged inside the brush body. The adjusting screw rod is fixedly connected to the adjacent two ends of the fixed rod. The slider is sleeved on the fixed rod and the adjusting screw rod. The slider is provided with a connection hole for connecting the inner layer of bristles. The adjusting screw rod is provided with an external thread, and the slider is provided with an internal thread hole matching the external thread of the adjusting screw rod;

[0007] A debris collection port is provided on the side surface of the brush body, and a collection bag is connected to the debris collection port. A magnetic attraction device is arranged inside the collection bag;

[0008] A lighting device is further arranged on the outer surface of the brush body.

[0010] For the motor grinding brush of the present invention, by arranging adjustable inner-layer bristles inside the brush body, the operator can adjust the protruding length of the inner-layer bristles by rotating the adjusting screw according to the cleaning requirements of different parts of the motor, so as to better clean various parts of the motor. The outer-layer bristles and the inner-layer bristles cooperate with each other to improve the cleaning effect. The debris collection port and the collection bag arranged on the side of the brush body are convenient for collecting the debris generated during the cleaning process. The magnetic attraction device in the collection bag can effectively adsorb metal debris, avoiding the flying of metal debris at the cleaning site or entering the motor interior to cause secondary pollution. The lighting device solves the lighting problem during the cleaning of the darker parts inside the motor, enabling the operator to observe the cleaning situation more clearly.

[0011] By arranging an adjustable bristle structure, the present invention can be adjusted according to the cleaning requirements of different parts of the motor, improving the cleaning effect; the arrangement of the debris collection device and the magnetic attraction device effectively collects the debris generated during the cleaning process, avoiding secondary pollution; the arrangement of the lighting device solves the lighting problem during the cleaning of the darker parts inside the motor, making the cleaning work more convenient and efficient. The grinding brush of the present invention has a reasonable structure, is easy to operate, has strong applicability, and has high practical value.

[0012] In a further technical solution, the hardness of the outer-layer bristles is greater than that of the inner-layer bristles. The outer-layer bristles are used to initially remove larger dirt and impurities on the surface of the motor, and the inner-layer bristles are used to carefully clean the more sensitive parts inside the motor to avoid damaging the motor components.

[0013] In a further technical solution, the other end of the adjusting screw is provided with a knob, which is convenient for the operator to rotate the adjusting screw to adjust the protruding length of the inner-layer bristles.

[0014] In a further technical solution, the collection bag is made of a transparent material, which is convenient for the operator to observe the collection situation of the debris in the collection bag and replace the collection bag in time.

[0015] In a further technical solution, the lighting device is an LED lamp. The LED lamp has the advantages of high brightness, low energy consumption, and long service life, and can meet the lighting requirements during the cleaning process.

[0016] In a further technical solution, the connecting part is a threaded connecting part, which is convenient for connecting with different types of driving devices, such as electric tools, pneumatic tools, etc., improving the applicability of the grinding brush.

[0017] [[ID=**]]In a further technical solution, the magnetic attraction device is a permanent magnet. The permanent magnet has strong magnetism, can effectively adsorb metal debris, and does not require an additional power supply, making it convenient to use.

[0018] In a further technical solution, the material of the brush body is high-strength plastic, which has the characteristics of light weight, high strength and wear resistance, can ensure the service life of the brush body, and at the same time reduce the overall weight of the grinding brush, making it convenient for the operator to use.
