DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of the present application.

[0030] The implementation of the heat dissipation type permanent magnet motor is as follows:

[0031] Embodiment one:

[0032] Please refer to Figure 1 - Figure 5 、 Figure 7 - Figure 14 A heat dissipation type permanent magnet motor, comprising a body 1, the outside of the body 1 is fixedly connected with a cooling cover 11 for heat dissipation of the permanent magnet motor, the outside of the cooling cover 11 is fixedly connected with a purification shell 12 for processing flowing air, the axis of the cooling cover 11 coincides with the axis of the body 1, the center line of the purification shell 12 coincides with the axis of the cooling cover 11, and the inside of the purification shell 12 communicates with the inside of the cooling cover 11.

[0033] The surface of the purification shell 12 is provided with an air inlet 13 for flowing air, the inner side of the air inlet 13 is fixedly connected with a filter plate 14 for filtering air dust, and the specifications of the air inlet 13 and the filter plate 14 are matched.

[0034] The inner side of the cooling cover 11 is movably connected with a measuring assembly 2 for sensing the temperature of the body 1, the measuring assembly 2 comprises an arc track 201 fixedly installed on the inner side of the cooling cover 11 to conduct the temperature of the body 1, a bending plate 202 slidably connected on the inner side of the arc track 201, a memory metal strip 203 fixedly installed on the outside of the bending plate 202 to sense the temperature of the body 1, and a contact 204 fixedly installed on the inside of the cooling cover 11, the memory metal strip 203 is fixedly connected with the inside of the arc track 201, and the bending plate 202 corresponds to the position of the contact 204.

[0035] The inside of the cooling cover 11 is fixedly connected with a support 3 for installing a part for generating flowing air, the outside of the support 3 is movably connected with a paddle plate 31 for generating directional flow, the outside of the body 1 is fixedly connected with a heat conduction strip 32 for conducting heat, the inside of the heat conduction strip 32 is provided with a cooling channel 33 for accelerating heat dissipation, the surface of the cooling cover 11 is provided with a groove 21 for the arc track 201 to contact the surface of the body 1, and the inside of the support 3 is fixedly connected with a second motor 35 for providing power to the paddle plate 31, and the second motor 35 is fixedly connected with the paddle plate 31 through a connecting shaft.

[0036] When the machine body 1 generates heat, the heat is conducted and dissipated to the air through the heat conduction strip 32. When the heat generated by the machine body 1 cannot be quickly dissipated through the heat conduction strip 32, the temperature of the machine body 1 rises above the normal operating temperature. The heat of the machine body 1 is conducted through the inside of the arc track 201 in contact with the surface of the machine body 1 through the groove 21. The temperature rise of the arc track 201 causes the memory metal strip 203 to expand and elongate, driving the bending plate 202 to slide inside the arc track 201. The bending plate 202 slides until it comes into contact with the contact 204 inside the cooling cover 11, thereby causing the second motor 35 to operate to drive the paddle plate 31 to rotate inside the cooling cover 11 under the support of the support 3. The rotation of the paddle plate 31 causes a negative pressure to be generated inside the cooling cover 11. The outside air enters the inside of the air inlet 13 under the action of the pressure difference. The air entering the inside of the air inlet 13 is filtered by the filter plate 14 inside the air inlet 13 and then enters the inside of the purification shell 12. The air inside the purification shell 12 enters the inside of the cooling cover 11. The air inside the cooling cover 11 is driven by the paddle plate 31 to enter the cooling channel 33 on the surface of the heat conduction strip 32 through the flow guide hole 34. The flowing air absorbs the heat of the heat conduction strip 32 to dissipate the heat of the machine body 1.

[0037] When the temperature of the machine body 1 cools down, the memory metal strip 203 cools down and shrinks, driving the bending plate 202 to slide away from the contact 204, thereby causing the second motor 35 to stop operating.

[0038] The surface of the cooling cover 11 is provided with a flow guide hole 34 in communication with the cooling channel 33. The heat conduction strips 32 are uniformly and circularly distributed on the outside of the machine body 1. The heat conduction strips 32 correspond in position and are matched in specification with the flow guide holes 34. The paddle plate 31 corresponds in position with the flow guide holes 34. The contact 204 is electrically connected with the second motor 35. The contact 204 is triggered, thereby causing the second motor 35 to be energized.

[0039] The heat generated by the machine body 1 during operation can be directly conducted and dissipated to the air through the heat conduction strip 32. The memory metal strip 203 senses the emergency overheating of the machine body 1 during operation, causing the bending plate 202 to move to trigger the contact 204 to complete the temperature sensing of the machine body 1. The paddle plate 31 operates to introduce the outside air into the cooling channel 33 inside the heat conduction strip 32 for air cooling and heat dissipation, thereby combining the heat sink and emergency air cooling and heat dissipation for the permanent magnet motor, increasing the heat dissipation effect of the permanent magnet motor.

[0042] A tuyere 13 for flowing air is formed in the surface of the purification shell 12, a filter plate 14 for filtering dust in the air is fixedly connected to the inner side of the tuyere 13, and a dust removal assembly 15 for cleaning dust in the inside of the filter plate 14 is movably connected to the inside of the purification shell 12.

[0043] The specification of the tuyere 13 matches that of the filter plate 14, the dust removal assembly 15 comprises a lead screw 151 movably connected to the inside of the purification shell 12 and used for cleaning dust on the surface of the filter plate 14, a storage plate 152 movably connected to the outside of the lead screw 151 and used for collecting air, a nozzle 153 fixedly connected to the outside of the storage plate 152 and used for generating high-pressure air injection to the filter plate 14, a first motor 154 fixedly connected to the outside of the purification shell 12 and used for providing rotary power to the lead screw 151, and an air pump 155 fixedly connected to the outside of the purification shell 12 and used for conveying external air into the inside of the storage plate 152.

[0044] When dust filtered and gathered in the inside of the filter plate 14 needs to be cleaned, the user operates the first motor 154 to drive the lead screw 151 to rotate in the inside of the purification shell 12, the lead screw 151 drives the storage plate 152 to slide in the inside of the purification shell 12, the storage plate 152 drives the nozzle 153 to reciprocally slide in the inside of the purification shell 12, the air pump 155 operates to convey external air into the inside of the storage plate 152 through a hose, air in the inside of the storage plate 152 enters the nozzle 153 and is compressed into high-pressure air flow which is blown into the inside of the filter plate 14, and dust in the inside of the filter plate 14 is cleaned under the blowing and washing of the high-pressure air flow.

[0045] The length of the lead screw 151 matches the length specification of the purification shell 12, the storage plate 152 is connected with the air pump 155 through the hose, the nozzle 153 corresponds to the position of the filter plate 14, and the first motor 154 is fixedly connected with the lead screw 151 through a connecting shaft.

[0046] The filter plate 14 filters and removes dust from the flowing air, the lead screw 151 moves to make the nozzle 153 move to blow and wash dust filtered and gathered in the inside of the filter plate 14 with high-pressure air, and thus the air dust filtered by the permanent magnet motor is automatically cleaned.

[0047] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary of the principles and application of the present application. Numerous modifications and adaptions can be effected without departing from the spirit and scope of the present application, which is not limited to the exact construction and arrangement described.
