[0002] Permanent magnet motors use permanent magnets to provide excitation, which makes the motor structure simpler, reduces processing and assembly costs, and eliminates slip rings and brushes that are prone to problems, thereby improving the reliability of motor operation. Since no excitation current is required and there is no excitation loss, the efficiency and power density of the motor are improved. However, dust and water entering the permanent magnet motor will affect its normal operation, so a waterproof and dustproof permanent magnet motor is needed.

[0003] After searching, for example, a Chinese patent application with application number CN219833875U discloses a waterproof and dustproof permanent magnet motor. During daily use, the waterproof and dustproof permanent magnet motor will generate vibration when the motor is running. The vibration will drive the moving block to move in the base, and then drive the telescopic rod to move up and down. The telescopic rod and spring are provided to buffer the vibration to prevent the normal operation of the machine from being affected by excessive vibration, thereby improving its practicality. During daily use, the waterproof and dustproof permanent magnet motor can intercept water or dust to the surface of the protective shell and the outside of the dustproof net through the protective shell and dustproof net, thereby preventing water or dust from entering the interior of the protective shell and then entering the motor body to damage its internal components and affect its normal operation, thereby extending its service life and increasing its practicality.

[0004] However, when the above technical solution is in use, there will be gaps at the output end, water seepage will occur, which will damage the permanent magnet motor. In addition, when the above technical solution is in use, it cannot effectively dissipate heat, thereby affecting the service life of the permanent magnet motor. In order to solve the above problems and defects, it is necessary to propose a new type of waterproof and dustproof permanent magnet motor. Summary of the invention

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in the field of permanent magnet motors without creative work are within the scope of protection of the utility model.

[0020] like Figure 1 and 2As shown, the utility model provides a waterproof and dustproof permanent magnet motor, including a motor body 1: an output rotating shaft 4 is fixedly provided at the output end of the motor body 1, and a connecting plate 7 is fixedly provided at one side of the motor body 1; a fixing frame 5 is fixedly provided at the lower end of the motor body 1, and bolt grooves 6 are respectively provided at the four corners of the lower end of the fixing frame 5.

[0021] In order to effectively prevent liquid from penetrating into the motor body 1, the output end and the rotation end of the motor body 1 are respectively provided with waterproof and anti-seepage devices 2 that can effectively prevent liquid from penetrating, which are used to discharge the penetrated liquid to avoid damaging the motor body 1; Figure 3 As shown, the waterproof and anti-seepage device 2 includes a limiting sleeve 21 and an arc groove 22. The limiting sleeve 21 is fixedly arranged on one side of the motor body 1, and the arc groove 22 is opened on the outer surface of the output rotating shaft 4. The arc groove 22 is located on the inner side of the limiting sleeve 21 and is movably connected with the limiting sleeve 21. The inner wall of the limiting sleeve 21 fits with the arc groove 22. A plurality of arc grooves 22 are arranged on the outer surfaces of the output rotating shaft 4 and the rotating shaft 35, and the arc grooves 22 on both sides are in opposite directions. When the output rotating shaft 4 and the rotating shaft 35 rotate clockwise, the plurality of arc grooves 22 scratch the limiting sleeve 21 in the outward direction, thereby guiding and discharging the liquid that has penetrated into the limiting sleeve 21, thereby effectively preventing the liquid from penetrating into the motor body 1.

[0022] Furthermore, in order to dissipate the heat of the motor body 1, a motor heat dissipation device 3 is provided on one side of the motor body 1 to dissipate the heat of the motor body 1, so as to prevent dust from dissipating the heat of the motor body 1 and to increase the service life of the motor body 1; Figure 4 As shown, the motor heat dissipation device 3 includes a flange ring 31 and screws 32. The flange ring 31 is penetrated by the screws 32 and is movably connected to the connecting disk 7. A connecting tube 33 is fixedly arranged on one side of the flange ring 31. A dust filter plate 34 is fixedly arranged on the inner wall of one side of the connecting tube 33. A plurality of air holes 37 are opened on one side of the connecting disk 7. A rotating shaft 35 is fixedly arranged on the rotating end of the motor body 1. A plurality of fan blades 36 are fixedly arranged on the outer surface of the rotating shaft 35. The rotation of the rotating shaft 35 drives the fan blades 36 to extract air, and the outside air is sucked into the connecting tube 33. The dust is then filtered by the dust filter plate 34. Therefore, the air flows into the air holes 37, thereby achieving the cooling effect of the utility model. Because the flange ring 31 is connected to the connecting disk 7 by screws 32, it is more convenient to disassemble and replace the dust filter plate 34 and the connecting tube 33. Moreover, because the fan blades 36 are fixedly connected to the rotating shaft 35, the use of redundant driving sources is reduced, thereby reducing the production cost.

[0023] The working principle is as follows: the utility model fixes the utility model by inserting bolts into the bolt grooves 6 in the fixing frame 5. When started, the motor body 1 drives the output rotating shaft 4 and the rotating shaft 35 to rotate. The waterproof and anti-seepage device 2 prevents liquid from penetrating into the motor body 1, thereby effectively achieving a waterproof effect, which provides a waterproof protection for the utility model. When the rotating shaft 35 rotates, it can drive the fan blades 36, and the motor heat dissipation device 3 can achieve cooling of the utility model, making the utility model more practical.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
