[0030] By adopting the above technical solution, when in use, the motor 2 works in the shell 1, and the sound insulation layer 6 arranged in the inner wall of the motor 2 can reduce the noise generated by the motor 2 in the shell 1 when it works. At the same time, a vibration reduction seat 5 is arranged between the motor 2 and the inner wall of the shell 1. The setting of the vibration reduction seat 5 can reduce the vibration generated by the motor 2 when it works, so as to achieve the effect of shock absorption. After working for a long time, the motor 2 will increase the temperature in the shell 1. In order to ensure the working environment of the motor 2, a cooling fan 7 is arranged at the left end of the shell 1. The cooling fan 7 blows air to the outside of the shell 1 when it works, so as to replace the hot air in the shell 1. When the cooling fan 7 works, the wind force generated by the cooling fan 7 and the vibration generated by the motor 2 will automatically open the cover 98, and the cover 98 is automatically opened to prevent the cover 98 from being blocked on the automatic cleaning mechanism 9, thereby hindering the normal operation of the cooling fan 7. A filter 8 is arranged on the left surface of the cooling fan 7. , the filter 8 can play a certain dust-proof effect, and the setting of the cover 98 can play a certain dust-proof effect. When the heat dissipation fan 7 is not working, the cover 98 is in a closed state, blocking the automatic cleaning mechanism 9 to prevent dust from entering the shell 1 through the filter 8. The cover 98 itself is made of metal. When not in use, it is rotated by the rotating shaft 93 to coincide with the cleaning ring 91, and the magnet 92 absorbs the cover 98 to fix it. Since the magnet 92 is small in size, the cover 98 can be closed on the cleaning ring 91 without being subjected to external force. When subjected to external force, the magnet 92 will not be able to absorb the cover 98, thereby causing the cover 98 to open automatically. At the same time, the working principle of the heat dissipation fan 7 is to suck out the hot air in the shell 1, not to blow air into the shell 1. At the same time, a filter 8 is also provided, so it can further prevent dust from entering the shell 1.

[0031] Specifically, Figures 4 to 6As shown, a magnet 92 is inlaid on the top left side of the cleaning ring 91, a rotating shaft 93 is movably installed on the bottom left side of the cleaning ring 91, the cover plate 98 is made of metal, and the cover plate 98 is installed on the left side of the cleaning ring 91 through the rotating shaft 93. A cleaning plate 95 is movably installed inside the cleaning ring 91, and a brush 97 is provided on the right end of the cleaning plate 95. The brush 97 is in contact with the filter screen 8. A rotating groove 94 is opened inside the cleaning ring 91, and rotating wheels 96 are movably installed on the upper and lower ends of the cleaning plate 95. The rotating wheel 96 is consistent with the rotating groove 94, and the cleaning plate 95 is inclined.

[0032] By adopting the above technical scheme, a cleaning ring 91 is installed at the left end of the shell 1, and a cleaning plate 95 is movably installed inside the cleaning ring 91. The right end of the cleaning plate 95 is provided with bristles 97, and the cleaning plate 95 is inclined. When the heat dissipation fan 7 starts to work and blow air outward, the cleaning plate 95 can be driven to rotate along the cleaning ring 91 through the rotating wheel 96. The cleaning plate 95 drives the bristles 97 while rotating, and the bristles 97 clean the filter 8. Thereby, the purpose of automatically cleaning the filter 8 can be achieved, and a layer of dust is prevented from adhering to the surface of the filter 8 after the device is used for a long time. At the same time, the heat dissipation fan 7 blows air to the outside, so that the dust swept by the bristles 97 of the cleaning plate 95 when it rotates will be directly blown outward, and there is no need to worry about the cleaned dust entering the shell 1 through the filter 8.

[0033] Working principle: When in use, the motor 2 works in the housing 1. The sound insulation layer 6 arranged in the inner wall of the motor 2 can reduce the noise generated by the motor 2 in the housing 1 when it is working. At the same time, a vibration reduction seat 5 is arranged between the motor 2 and the inner wall of the housing 1. The setting of the vibration reduction seat 5 can reduce the vibration generated by the motor 2 when it is working, so as to achieve the effect of shock absorption. After working for a long time, the motor 2 will increase the temperature in the housing 1. In order to ensure the working environment of the motor 2, a cooling fan 7 is arranged at the left end of the housing 1.

When the cooling fan 7 is working, the wind force generated and The vibration generated by the motor 2 will automatically open the cover 98, and the automatic opening of the cover 98 prevents the cover 98 from being blocked on the automatic cleaning mechanism 9 and hindering the normal operation of the cooling fan 7. A filter screen 8 is arranged on the left surface of the cooling fan 7, and the filter screen 8 can play a certain dust-proof effect. At the same time, the setting of the cover 98 can play a certain dust-proof effect.

The cover 98 itself is made of metal. When not in use, it is rotated by the rotating shaft 93 to coincide with the cleaning ring 91, and the magnet 92 absorbs Attach the cover plate 98 to fix it. Since the magnet 92 is small in size, the cover plate 98 can be closed on the cleaning ring 91 without external force. When it is subjected to external force, the magnet 92 will not be able to attract the cover plate 98, thereby causing the cover plate 98 to open automatically. At the same time, the working principle of the heat dissipation fan 7 is to suck out the hot air in the shell 1, not to blow air into the shell 1. At the same time, a filter screen 8 is also provided, so that dust can be further prevented from entering the shell 1. A cleaning ring 91 is installed at the left end of the shell 1, and a cleaning plate 95 is movably installed inside the cleaning ring 91. A brush is provided at the right end of the cleaning plate 95. 97, and the cleaning plate 95 is inclined. When the heat dissipation fan 7 starts to work and blows air outward, the cleaning plate 95 can be driven to rotate along the cleaning ring 91 through the rotating wheel 96. The cleaning plate 95 drives the brush 97 while rotating, and the brush 97 cleans the filter 8, thereby achieving the purpose of automatically cleaning the filter 8, and avoiding a layer of dust adhering to the surface of the filter 8 after the device is used for a long time. At the same time, the heat dissipation fan 7 blows air to the outside, so that the dust swept by the brush 97 of the cleaning plate 95 during rotation will be directly blown outward, and there is no need to worry about the cleaned dust entering the housing 1 through the filter 8.
