Description

Technical Field

[0001] The utility model relates to the field of dust extraction pumps, and particularly relates to a heat dissipation device for a dust extraction pump motor. Background Technique

[0002] A dust extraction pump is a device used to extract air and debris, and is widely used in industrial, commercial, and household fields. The dust extraction pump drives the impeller to rotate through an electric motor, so that the air inside the machine is extracted, thereby generating a pressure difference, that is, negative pressure, inside and outside the machine. The higher the negative pressure, the stronger the suction force.

[0003] After the dust extraction pump works for a long time, the electric motor will generate a large amount of heat. Conventional dust extraction pumps do not have a heat dissipation device, and only dissipate heat to the air through the housing of the electric motor, and the heat dissipation effect is poor. When the temperature of the electric motor is relatively high, it is easy to cause the electric motor to malfunction, affecting the service life of the dust extraction pump, so further improvement can be made.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1 - 4 shown, a heat dissipation device for a dust extraction pump motor includes a pump housing 100. A motor 200 is installed at the center of the right side of the pump housing 100. The front side of the bottom of the pump housing 100 is fixed and connected to an input end 101, and the rear side of the top of the pump housing 100 is fixed and connected to an output end 102. A filter assembly 300 is welded to the bottom of the pump housing 100. An intake pipe 400 is provided between the right end of the filter assembly 300 and the right end of the motor 200. An exhaust pipe 500 is provided between the left end of the motor 200 and the input end 101. A support assembly 600 is provided between the bottom of the motor 200 and the filter assembly 300.

[0021] During use, the exhaust pipe 500 includes a large-diameter pipe 501. A conical pipe 502 is integrally formed at the rear end of the large-diameter pipe 501. A small-diameter pipe 503 is integrally formed at the rear end of the conical pipe 502. The rear end of the small-diameter pipe 503 is fixedly installed with the front end of the input end 101. The impeller inside the pump housing 100 is driven to rotate by the motor 200, so that external air enters the pump housing 100 through the input end 101. The external air sequentially passes through the large-diameter pipe 501, the conical pipe 502, and the small-diameter pipe 503 and enters the inside of the input end 101. Through the setting of the conical pipe 502, the air flow rate will increase. A third connecting pipe 504 is fixedly connected to the surface of the small-diameter pipe 503. The other end of the third connecting pipe 504 is fixedly installed with a second bellows 505. The other end of the second bellows 505 is fixedly installed with a fourth connecting pipe 506. The other end of the fourth connecting pipe 506 is fixedly installed at the bottom of the left end of the housing of the motor 200. Since the air flow rate at the small-diameter pipe 503 is relatively fast and the air pressure is relatively lower than the air pressure inside the third connecting pipe 504, the hot air inside the motor 200 passes through the fourth connecting pipe 506, the second bellows 505, and the third connecting pipe 504 and enters the inside of the small-diameter pipe 503, achieving the purpose of cooling the inside of the motor 200.

[0022] Through the setting of the second bellows 505, when the motor 200 vibrates during operation, the fourth connecting pipe 506 can move relative to the third connecting pipe 504. The end of the third connecting pipe 504 away from the second bellows 505 is inclined backward, thus preventing external air from flowing backward into the inside of the motor 200 through the third connecting pipe 504 when passing through the small-diameter pipe 503 and avoiding dust from entering the motor 200. A dust-proof ring 507 is fixedly installed on the inner wall of the small-diameter pipe 503. The front end of the dust-proof ring 507 is fixedly installed on the inner wall of the small-diameter pipe 503. The end of the third connecting pipe 504 away from the second bellows 505 faces the outer wall of the dust-proof ring 507. By blocking the end of the third connecting pipe 504 with the dust-proof ring 507, it further prevents dust from entering the third connecting pipe 504 from the small-diameter pipe 503.

[0023] Specifically, the filtering component 300 includes a square cylinder 301 welded to the bottom of the pump housing 100. The inside of the square cylinder 301 is filled with filter cotton 302. A filter plate 303 is attached to the left end of the square cylinder 301. A top plate 304 is integrally formed on the top of the filter plate 303. Side baffles 305 are integrally formed on both the front and rear sides of the filter plate 303. Clamping plates 306 are fixedly installed on both the front and rear sides of the left end of the square cylinder 301. The clamping plates 306 are L-shaped when viewed from above, so that the side baffles 305 can be inserted between the clamping plates 306 and the square cylinder 301. Through holes are formed through the surfaces of the side baffles 305 and the clamping plates 306, and the side baffles 305 and the clamping plates 306 are connected by bolts. External air can pass through the filter plate 303 and enter the inside of the square cylinder 301, and the dust is intercepted by the filter cotton 302. In practice, lugs 307 are fixedly installed on both the front and rear sides of the bottom of the square cylinder 301. The square cylinder 301 can be used as the base of the pump housing 100 and the motor 200, and then the pump housing 100 and the motor 200 are installed on a desktop or a tabletop through the cooperation of the lugs 307 and bolts. The intake pipe 400 includes a connecting pipe one 401 fixedly installed on the right end of the square cylinder 301. The connecting pipe one 401 is communicated with the inside of the square cylinder 301. A corrugated pipe one 402 is fixedly installed at the top end of the connecting pipe one 401. The other end of the corrugated pipe one 402 is fixedly installed with a connecting pipe two 403. The connecting pipe two 403 is fixedly installed at the bottom right end of the housing of the motor 200, and the connecting pipe two 403 is communicated with the inside of the housing of the motor 200. Since the hot air inside the motor 200 enters the input end 101 through the exhaust pipe 500, the inside of the motor 200 is in a negative pressure state, so that external air can pass through the filter plate 303, the square cylinder 301, the connecting pipe one 401, the corrugated pipe one 402 and the connecting pipe two 403 and enter the inside of the motor 200. Thus, by allowing external air to enter the inside of the motor 200, the inside of the motor 200 is cooled.

[0024] In reality, the support component 600 includes a hoop 601 fixedly installed on the outside of the motor 200. A U-shaped plate 602 is welded to the bottom of the hoop 601. Guide plates 603 are attached to both the front and rear sides of the U-shaped plate 602. The guide plates 603 are U-shaped when viewed from above. A spring 604 is fixedly installed at the bottom of the U-shaped plate 602. The bottom end of the spring 604 is fixedly installed on the top of the filtering component 300. Rubber sheets 605 are bonded to the inner sides of the guide plates 603. Through the elasticity of the spring 604, the U-shaped plate 602 and the hoop 601 are supported, and further the motor 200 is supported. When the motor 200 vibrates during operation, the hoop 601 and the U-shaped plate 602 can move up and down. The moving path of the U-shaped plate 602 is guided by the guide plates 603. Then, the movement of the U-shaped plate 602 is inhibited by the friction between the rubber sheets 605 and the U-shaped plate 602.

[0025] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
