[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a waterproof and dustproof permanent magnet motor, which aims to solve the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a waterproof and dustproof permanent magnet motor, including a motor body, on which a protective component is provided;

[0007] The protective assembly includes a first connecting cover disposed at one end of the motor body for protection, and a second connecting cover disposed at the other end of the motor body for protection.

[0008] The motor body has a baffle plate embedded inside for blocking, and a filter cloth for filtering is provided on one side of the baffle plate. Several flow guide grooves for guiding flow are distributed on the baffle plate. A rotor is provided in the middle of the motor body, and a stator is provided on the outside of the rotor. The stator is mounted on the motor body, and several coil groups are inserted into the stator. A rotating shaft is provided in the middle of the rotor, and the rotating shaft is detachably connected to the rotor by bolts.

[0009] As can be seen, in the above technical solution, the first and second connecting covers provide the first protection to prevent the rotor, stator, and coil assembly inside the motor body from being damaged by external forces. At the same time, the airflow is transported to the motor body through the inclined surface of the guide groove on the baffle plate to dissipate heat from the rotor, stator, and coil assembly. Water stains are blocked on one side of the baffle plate by the inclined surface of the guide groove to prevent water stains from entering the motor body. Meanwhile, the filter cloth on one side of the baffle plate is used to filter dust and impurities in the airflow to prevent dust and impurities from entering the motor body, thus ensuring the dustproof and waterproof effect of the device.

[0010] Optionally, in a possible implementation, one end of the rotating shaft is rotatably connected to a limiting sleeve, the limiting sleeve is mounted on the second connecting cover by bolts, the middle of the limiting sleeve is rotatably connected to a docking shaft, the docking shaft is fixed to one end of the rotating shaft by bolts, both ends of the motor body are provided with chucks, and each chuck is detachably connected to the first connecting cover and the second connecting cover by bolts, and the bottom of each of the two chucks is fixedly provided with a supporting inclined foot, the vertical cross-sectional shape of the supporting inclined foot is set to a figure-eight shape;

[0011] As can be seen, in the above technical solution, the stator and coil group form a magnetic channel, which causes the rotor to rotate under the influence of magnetic force, causing the rotating shaft to drive the docking shaft to rotate. Furthermore, the chuck and support foot are designed to facilitate the support of the device during installation, and also to ensure the stability of the various structures when the first connecting cover and the second connecting cover are installed on the upper motor body.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] By setting up protective components, the overall design is simple and the structure is reasonable compared with the existing technology. Through the corresponding cooperation of various structures, the stator and coil group form a magnetic channel, which causes the rotor to rotate under the influence of magnetic force, and the rotating shaft drives the docking shaft to rotate.

[0014] Furthermore, during use, the first and second connecting covers provide initial protection to prevent damage to the rotor, stator, and coil assembly inside the motor body from external forces. Simultaneously, the airflow is transported through the inclined surface of the guide groove on the baffle plate to the motor body to dissipate heat from the rotor, stator, and coil assembly. Meanwhile, water stains are blocked on one side of the baffle plate by the inclined surface of the guide groove, preventing water stains from entering the motor body. Attached Figure Description

[0023] As attached Figures 1-5The waterproof and dustproof permanent magnet motor shown is protected by protective components on the motor body 1. The first connecting cover 2 and the second connecting cover 3 provide initial protection to prevent the rotor 6, stator 7 and coil group 8 inside the motor body 1 from being damaged by external forces. At the same time, the airflow is transported to the motor body 1 through the inclined surface of the guide groove 5 on the baffle plate 4 to dissipate heat from the rotor 6, stator 7 and coil group 8. Water stains are blocked on one side of the baffle plate 4 by the inclined surface of the guide groove 5 to prevent water stains from entering the motor body 1. At the same time, the filter cloth on one side of the baffle plate 4 is used to filter dust and impurities in the airflow to prevent dust and impurities from entering the motor body 1, ensuring the dustproof and waterproof effect of the device. The specific structural settings of the components are as follows.

[0024] The protective components include a first connecting cover 2 for protection at one end of the motor body 1, and a second connecting cover 3 for protection at the other end of the motor body 1;

[0025] The motor body 1 has a baffle plate 4 embedded inside for partitioning, and a filter cloth for filtration is provided on one side of the baffle plate 4. Several guide grooves 5 for guiding flow are distributed on the baffle plate 4. A rotor 6 is provided in the middle of the motor body 1, and a stator 7 is provided on the outside of the rotor 6. The stator 7 is mounted on the motor body 1, and several coil groups 8 are inserted into the stator 7. A rotating shaft 9 is provided in the middle of the rotor 6, and the rotating shaft 9 is detachably connected to the rotor 6 by bolts.

[0026] One end of the rotating shaft 9 is rotatably connected to a limiting sleeve 10. The limiting sleeve 10 is installed on the second connecting cover 3 by bolts. The middle part of the limiting sleeve 10 is rotatably connected to a docking shaft 11. The docking shaft 11 is fixed to one end of the rotating shaft 9 by bolts. Both ends of the motor body 1 are provided with chucks 12, and each chuck 12 is detachably connected to the first connecting cover 2 and the second connecting cover 3 by bolts. The bottom of each of the two chucks 12 is fixedly provided with a support inclined foot 13. The vertical cross-section shape of the support inclined foot 13 is set as a figure-eight shape.

[0027] According to the above structure, when in use, the staff installs the device in the designated position. When in use, the motor body 1 is connected to the power supply, the stator 7 and the coil group 8 form a magnetic channel, which causes the rotor 6 to be affected by the magnetic force and rotate, so that the rotating shaft 9 drives the docking shaft 11 to rotate.

[0028] Furthermore, during use, the first connecting cover 2 and the second connecting cover 3 provide initial protection to prevent the rotor 6, stator 7 and coil group 8 inside the motor body 1 from being damaged by external forces. At the same time, the airflow is transported to the motor body 1 through the inclined surface of the guide groove 5 provided on the baffle plate 4 to dissipate heat from the rotor 6, stator 7 and coil group 8. Meanwhile, water stains are blocked on one side of the baffle plate 4 by the inclined surface of the guide groove 5, preventing water stains from entering the motor body 1.

[0029] Meanwhile, the filter cloth set on one side of the baffle plate 4 is used to filter dust and impurities in the airflow, preventing dust and impurities from entering the motor body 1 and ensuring the dustproof and waterproof effect of the device.

[0030] Furthermore, the chuck 12 and the support foot 13 facilitate the support of the device during installation, and also improve the stability of the first connecting cover 2 and the second connecting cover 3 when they are installed on the upper motor body 1.

[0031] Unlike existing technologies, this application discloses a waterproof and dustproof permanent magnet motor. The motor is first protected by a first connecting cover 2 and a second connecting cover 3 to prevent damage to the rotor 6, stator 7, and coil assembly 8 inside the motor body 1 from external forces. Simultaneously, airflow is transported through the inclined surface of the guide groove 5 on the baffle plate 4 to the motor body 1 to dissipate heat from the rotor 6, stator 7, and coil assembly 8. Water is blocked by the inclined surface of the guide groove 5 on one side of the baffle plate 4, preventing water from entering the motor body 1. Furthermore, a filter cloth on one side of the baffle plate 4 filters dust and impurities in the airflow, preventing them from entering the motor body 1, thus ensuring the device's dustproof and waterproof performance.
