Description

Technical Field

[0001] The utility model belongs to the technical field of motor accessories, and in particular relates to a motor auxiliary exhaust component. Background Art

[0002] When the motor is running, it will continue to generate a large amount of heat energy. If the heat cannot be effectively and promptly removed, the motor will overheat, which will not only interfere with its normal operation, but also cause damage in severe cases. Current technical means mainly use fan blades and exhaust holes to enhance the heat dissipation effect. However, this method has obvious defects, that is, the exhausted hot air is still trapped around the motor, which will undoubtedly further increase the air temperature around the motor. What's more disadvantageous is that the fan will blow the hot air back into the motor. Such a design obviously cannot meet the needs of long-term and stable operation of the motor. Therefore, in order to ensure the normal operation of the motor and extend its service life, it is urgent to develop a new type of auxiliary heat dissipation structure. Utility Model Content

[0003] In order to solve the problems raised in the above-mentioned background technology, the utility model provides the following technical solutions: an auxiliary exhaust component of a motor, comprising a rotor, a motor end cover, and a first fan blade, the motor end cover is open at both ends, the motor end cover is connected to an auxiliary exhaust assembly, the auxiliary exhaust assembly comprises two air guide half-sleeves, an air guide pipe body, an air guide end cover, and a second fan blade, the inner wall of the air guide half-sleeve is provided with a guide groove, the air guide pipe body is connected to the end of the air guide half-sleeve, the air guide pipe body is communicated with the guide groove, the end of the air guide pipe body away from the air guide half-sleeve is communicated with the air guide end cover, the air guide end cover is single-end open, the open end of the air guide end cover is arranged away from the motor end cover, the two air guide half-sleeves are connected by a snap block, the second fan blade is installed in the air guide end cover, and the second fan blade is connected to the rotor.

[0004] Furthermore, sealing strips are provided at both left and right ends of the air guide half sleeve.

[0005] Furthermore, the outer wall of the motor end cover is provided with a hanging ear, and the motor end cover is slidably connected to the air guide pipe body through the hanging ear.

[0006] Furthermore, a fitting block is provided on the outer wall of the air guide half sleeve, and the fitting block is provided with a fitting groove matched with the buckle block.

[0007] Furthermore, an anti-disassembly blocking piece is provided at the end of the fitting block, and the end of the anti-disassembly blocking piece is flush with the end of the buckle block.

[0008] Furthermore, an adapter sleeve is sleeved on one end of the air guide tube body away from the air guide half sleeve, and the air guide tube body is connected to the air guide end cover through the adapter sleeve.

[0009] Furthermore, the distance between the air guide end cover and the motor end cover is not less than 10 cm.

[0010] Furthermore, the second fan blade is an impeller.

[0011] The beneficial effects of the utility model are as follows: through the two fan blades driven by the motor, the first fan blade introduces cold air into the motor housing for heat exchange, while the second fan blade accelerates the discharge of hot air in the air guide end cover, thereby achieving an efficient heat dissipation effect and discharging the hot air to an area far away from the motor. This two-way heat dissipation mechanism significantly improves the heat dissipation efficiency of the motor and extends the service life of the motor; the design of the air guide half-sleeve allows its inner diameter to adapt to the outer wall of the motor of different shapes, thereby improving the versatility and adaptability of the exhaust component. In addition, the air guide half-sleeve is connected by a buckle block and a fitting groove, which simplifies the assembly process and improves the assembly efficiency; the sealing strip design of the air guide half-sleeve improves the degree of fit with the motor surface and effectively prevents the leakage of hot air. At the same time, the design of the anti-disassembly baffle can prevent the buckle block from being removed by unauthorized personnel, ensuring the stability and safety of the exhaust component; the split structure between the air guide tube body and the air guide end cover is easy to assemble and disassemble, providing convenience for subsequent maintenance and replacement. In addition, by observing whether the gap between the anti-tampering baffle and the buckle block is uniform, it can be determined whether after-sales service is required, which improves the user experience; the second fan blade adopts an impeller design with larger blades, which can generate faster air flow at the same speed, thereby more effectively exporting heat from the motor. This design optimizes the airflow path and improves the heat dissipation effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In this embodiment, a hanging ear 11 is provided on the outer wall of the motor end cover 2 , and the motor end cover 2 is slidably connected to the air guide pipe body 5 via the hanging ear 11 .

[0026] The above structure makes it easy to adjust the distance between the motor end cover 2 and the air guide half sleeve 4.

[0027] In this embodiment, a fitting block 12 is disposed on the outer wall of the air guide half sleeve 4 , and the fitting block 12 is provided with a fitting groove 13 matched with the buckle block 9 .

The hot air flows through the exhaust air guide pipe body 5 and is discharged into the air guide end cover 6. The second fan blade 7 rotates, so that the air pressure at the open end of the air guide end cover 6 is lower, and the air in the air guide pipe body 5 is accelerated to flow out to the low-pressure area, so that the hot air is quickly discharged.
