[0020] Embodiment 1

[0021] As Figure 1 , Figure 2 ,Figure 3 As shown, the ultra-high efficiency energy-saving permanent magnet motor in this example includes a permanent magnet motor body 1, a heat dissipation mechanism, and a dust prevention mechanism. The fan in the heat dissipation mechanism is installed on the motor shaft end portion in the permanent magnet motor body 1. For detailed structure, please refer to the patent file of CN220510919U. For the permanent magnet motor body, the structure of installing the stator and rotor in the common shell is as usual. For the rotor, the through-shaped slot cavity is formed in the middle part of the rotor core, the magnetic steel is embedded in the slot cavity, and the baffle is installed to cover both ends of the rotor core. The filler port can be formed on the baffle corresponding to the opening position of the slot cavity. The edge of the filler port is hinged to the sealing plate. The sealing plate can be clamped with the filler port to complete the plugging structure, and the like. It can be freely selected according to the requirements.

[0022] The dust prevention mechanism in this example includes a cylinder body one 2, a cylinder body two 3, and a filter screen 5. The filter screen 5 is fixed in the cylinder cavity of the cylinder body two 3. A cross-shaped support 36 can also be fixed at the cylinder port in front of the filter screen 5, which helps to improve the structural strength of the cylinder body two. The cylinder body one 2 is sleeved at the end portion of the permanent magnet motor body 1 and is fastened by screws and the like. The fan is in the cavity surrounded by the cylinder body one 2 and the shell in the permanent magnet motor body 1.

[0023] In this example, the cylinder body two 3 is installed at the axially formed mounting hole 31 in the middle of the end face of the cylinder body one 2. The first end portion peripheral wall of the cylinder body one 2 is radially outwardly extended to form a limiting plate one 4, and the tail end of the cylinder body one 2 is installed with an annular limiting plate two 32. The outer diameters of the limiting plate one 4 and the limiting plate two 32 are both greater than the hole diameter of the mounting hole 31. The limiting plate two 32 is an annular body formed of elastic material, such as plastic material, which can be deformed after being squeezed. The limiting plate two 32 is sleeved in the circumferentially extending mounting groove at the tail end of the cylinder body two 3.

[0024] During installation, after the cylinder body two is corresponded to the mounting hole, the cylinder body two can be directly pressed into the mounting hole. The limiting plate two protrudes outward at the tail end hole of the mounting hole, and the limiting plate one protrudes outward at the first end hole of the mounting hole. The limiting plate one and the limiting plate two cooperate with the end face of the corresponding mounting hole to limit the cylinder body two in the mounting hole.

[0025] To reduce the vibration noise, an elastic layer 35, such as rubber material, can also be covered on the end face of the limiting plate one 4 towards the cylinder body one 2. The elastic layer is attached to the end face of the cylinder body one, and the elastic layer provides cushioning to reduce the noise generated by vibration.

[0026] In this example, the limiting plate one 4 is provided with a clamping plate hinged for finger force. Specifically, a relative forming seat groove 37 is formed at the end face of the limiting plate one 4, which extends radially to the peripheral wall of the limiting plate one 4. The rectangular plate body 33 of the clamping plate is at the seat groove 37, and the tail end of the plate body 33 is formed with a pivot on both sides. The hinge hole is formed at the corresponding side groove wall of the mounting groove. The clamping plate and the limiting plate one form a hinged structure through the pivot hinge hole. The clamping plate can be conveniently fingered by being radially arranged to axially arranged.

[0027] The plate body 33 of the clamping plate can be in interference fit with the groove wall of the installation groove 37 to improve the stability of installation. The first end of the plate body can be bent. An arc-shaped groove 34 is formed on the end face of the bent portion towards the outside. A finger can be pressed on the arc-shaped groove to facilitate force. Then the plate body can be converted from radial to axial. The finger can be buckled to exert force to pull out the second cylinder.

[0028] A notch 38 can also be formed on the top wall of the hinge hole. The width of the notch 38 is smaller than the diameter of the pivot to limit the disengagement of the pivot. However, the pivot can be directly pressed into the hinge hole during installation to facilitate assembly.

[0029] When the first cylinder and the second cylinder are connected, they can be directly pressed in. When disassembled, the clamping plate can be rotated to the appropriate position. Then the finger can be forced to pull out the second cylinder. The filter screen can be easily cleaned, and the installation and disassembly are convenient.

[0030] The above is only the preferred embodiment of the present application. The protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solution that belongs to the idea of the present application is within the protection scope of the present application. It should be noted that for ordinary technical personnel in the technical field, some improvements and decorations without departing from the principle of the present application are also considered as the protection scope of the present application.
