[0002] A motor refers to an electromagnetic device that realizes the conversion or transmission of electrical energy based on the law of electromagnetic induction. As a power source for electrical appliances or various machines, its main function is to convert electrical energy into mechanical energy.

[0003] During the operation of the motor, heat will be generated. However, the traditional motor is a relatively enclosed device, and the generated heat is not easily dissipated, resulting in an increase in the temperature inside the motor. The increase in the motor temperature will cause the motor to demagnetize, thus affecting the performance and lifespan of the motor. Therefore, heat dissipation for the motor is required.

[0004] In the prior art, a method of opening a plurality of heat dissipation holes on the casing of the motor is adopted for heat dissipation. However, after long-term use, dust and impurities are likely to adhere to the inside of the heat dissipation holes, resulting in blockage. Since the heat dissipation holes are small and located on the casing, it is very difficult to clean them, thus easily leading to poor heat dissipation and affecting the heat dissipation effect of the motor.

[0006] The utility model realizes the above purpose through the following technical solutions. A motor of an oil fume extractor includes a casing. A plurality of ventilation openings are evenly arranged along the circumference on the side wall of the casing. The ventilation openings are communicated with the inside of the casing. A plurality of dust-proof guard plates for closing the ventilation openings are arranged on the side wall of the casing. A plurality of heat dissipation holes are opened on the dust-proof guard plates. A plurality of locking components are evenly arranged along the circumference on the side wall of the casing. The locking components are used to detachably install the dust-proof guard plates on the ventilation openings.

[0007] As a further setting of the utility model, guiding sliding rails are arranged at both positions on both sides of the ventilation opening. The dust-proof guard plate is used to be inserted between the guiding sliding rails. The cross section of the dust-proof guard plate is arc-shaped.

[0008] As a further setting of the utility model, the locking component includes a socket fixedly connected to the side wall of the casing. A inserting piece for inserting into the inside of the socket is arranged on the dust-proof guard plate.

[0009] As a further setting of the utility model, the locking component includes a locking screw threadedly connected to the socket. A threaded hole matching the locking screw is opened on the inserting piece.

[0010] As a further configuration of the utility model, the locking screw is provided with an elastic gasket for contacting with the inner bottom wall of the threaded hole.

[0011] As a further configuration of the utility model, one end of the locking screw away from the elastic gasket is connected to a holding knob.

[0012] As a further configuration of the utility model, a plurality of anti-slip grooves are evenly arranged on the side wall of the gripping knob along the circumferential direction.

[0013] As a further configuration of the utility model, a paddle is provided on a side of the dustproof guard plate away from the inserting piece.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model dissipates heat through the ventilation openings and the heat dissipation holes, and because the ventilation openings are closed by the dustproof guard plates during daily use, large pieces of dust and impurities can be blocked from entering the interior of the casing through filtering through the heat dissipation holes, thereby achieving a good dust-proof effect. Moreover, when the interior of the heat dissipation holes is clogged with dust and impurities due to long-term use, the locking assembly for the dustproof guard plates can be released, and the dustproof guard plates can be removed separately for flushing, thereby enabling the heat dissipation holes to be thoroughly cleaned, and the cleaning operation is relatively convenient and simple. After cleaning, the dustproof guard plates can be reinstalled on the ventilation openings, thereby always ensuring smooth heat dissipation, and the motor has a good heat dissipation effect.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-3 As shown, a motor of an oil fume extractor includes a housing 1. A plurality of ventilation openings 2 are evenly formed in the side wall of the housing 1 in the circumferential direction, and the ventilation openings 2 are communicated with the inside of the housing 1. A plurality of dust-proof guard plates 3 for closing the ventilation openings 2 are arranged on the side wall of the housing 1, and a plurality of heat dissipation holes 4 are formed in the dust-proof guard plates 3. A plurality of locking components are evenly arranged on the side wall of the housing 1 in the circumferential direction. The locking components are used to detachably mount the dust-proof guard plates 3 on the ventilation openings 2. When the motor generates heat during operation, the heat can be dissipated into the air through the ventilation openings 2 and the heat dissipation holes 4 in sequence to achieve heat dissipation. And since the ventilation openings 2 are closed by the dust-proof guard plates 3 during daily use, through the filtration of the heat dissipation holes 4, large dust impurities can be blocked from entering the inside of the housing 1, playing a good dust-proof role. And when the inside of the heat dissipation holes 4 is blocked by dust impurities due to long-term use, the locking of the dust-proof guard plates 3 by the locking components can be released, and the dust-proof guard plates 3 can be separately disassembled and washed, so that the heat dissipation holes 4 can be thoroughly cleaned. The cleaning operation is relatively convenient and simple. After the cleaning is completed, the dust-proof guard plates 3 can be reinstalled on the ventilation openings 2 to always ensure smooth heat dissipation, so that the motor has a good heat dissipation effect.

[0023] Please refer to Figure 1 、 Figure 2 As shown, guiding slide rails 5 are arranged on both sides of the ventilation openings 2. The dust-proof guard plates 3 are used to be inserted between the guiding slide rails 5, and the cross section of the dust-proof guard plates 3 is arc-shaped, so it fits with the side wall of the housing 1. The dust-proof guard plates 3 can be conveniently inserted vertically between the guiding slide rails 5. Through the limitation of the guiding slide rails 5 on the dust-proof plates, the installation of the dust-proof guard plates 3 on the housing 1 can be realized. And when it is necessary to disassemble the dust-proof guard plates 3, only the dust-proof guard plates 3 need to be pulled out from between the guiding slide rails 5, so that the disassembly and assembly of the dust-proof guard plates 3 are relatively convenient and simple.

[0024] Please refer to Figure 1 、 Figure 3 、 Figure 4As shown, the locking assembly includes a socket 6 fixedly connected to the side wall of the housing 1, and a plug 7 for inserting into the socket 6 is provided on the dust shield 3. After the dust shield 3 is inserted between the guide rails 5, the plug 7 will be inserted into the socket 6. The socket 6 limits the plug 7, which can play a locking role and improve the installation firmness of the dust shield 3 on the vent 2. The locking assembly includes a locking screw 8 threadedly connected to the socket 6, and a threaded hole 9 matching the locking screw 8 is opened on the plug 7. When the plug 7 is inserted After the socket 6 is inserted into the socket 6, the locking screw 8 can be screwed into the threaded hole 9. The threaded connection between the locking screw 8 and the threaded hole 9 can completely lock the insert 7 in the socket 6, thereby achieving fixed installation of the dustproof guard 3 on the vent 2 to prevent the dustproof guard 3 from falling off. An elastic gasket 10 for contacting with the inner bottom wall of the threaded hole 9 is provided on the locking screw 8, and the elastic gasket 10 is made of rubber material. After the locking screw 8 is screwed into the threaded hole 9, the elastic gasket 10 is pressed by the locking screw 8. The locking screw 8 is tightly pressed against the bottom wall of the threaded hole 9, so that the elastic gasket 10 is elastically deformed, thereby applying a thrust to the locking screw 8 in the reverse direction, so that the engagement between the locking screw 8 and the threaded hole 9 is tighter, thereby improving the connection firmness between the locking screw 8 and the insert 7, and further improving the installation stability of the dust shield 3 on the vent 2. A holding knob 11 is connected to the end of the locking screw 8 away from the elastic gasket 10. When the locking screw 8 needs to be screwed into the threaded hole 9, the holding knob 11 can be held for screwing. The gripping and twisting setting provides a force point for the twisting operation, making the operation easier and more labor-saving, and a number of anti-slip grooves 12 are evenly arranged on the side wall of the gripping knob 11 along the circumferential direction, thereby greatly increasing the friction coefficient on the side wall of the gripping knob 11, making it less likely to slip when twisting the gripping knob 11, and more labor-saving, wherein a paddle 13 is provided on the side of the dust guard 3 away from the insert 7, and when the dust guard 3 needs to be removed, the dust guard 3 can be pulled out from between the guide rails 5 by simply prying the paddle 13, making it more convenient to remove the dust guard 3.
