[0032] like Figure 1-9As shown, an integrated heat dissipation motor is described in detail:

[0033] An integrated heat dissipation motor includes an inner sleeve 301 with a plurality of magnets uniformly arranged on the inner wall, a plurality of ventilation grooves 302 uniformly arranged on the outer surface of the inner sleeve 301 in a circumferential direction, a middle sleeve 201 is sleeved on the outer surface of the inner sleeve 301, a front blocking plate 202 is fixed to the front end of the middle sleeve 201, a fixing ring 203 is fixed to the rear end of the middle sleeve 201, a rear blocking plate 401 is mounted on the fixing ring 203, a rotor coaxially rotates in the inner sleeve 301, a central axis 501 at the center of the rotor passes through the front blocking plate 202 and the rear blocking plate 401 at front and rear ends respectively, and a fan blade 602 rotates at the rear end of the central axis 501.

[0034] The inner sleeve 301, the middle sleeve 201, the front blocking plate 202 and the rear blocking plate 401 form an integrated inner space, and the rotor is supported by the central axis 501, so that the rotor can rotate in the inner sleeve 301, and when the inner sleeve 301 rotates, the fan blades 602 are driven to rotate, and the rotating fan blades 602 will suck the air at the rotor, blow it to the rear blocking plate 401, and then flow to the middle sleeve 201 after being blocked by the rear blocking plate 401, and then blow to the front blocking plate 202 through the multiple ventilation grooves 302 on the surface of the inner sleeve 301, and then return to the rotor inside the inner sleeve 301, so that the air in the internal space of the motor can flow fully, take away the heat from the rotor and the inner sleeve 301, transfer it to the middle sleeve 201, and dissipate it to the outside through the outer surface of the middle sleeve 201 to complete the heat dissipation. Since the air in the internal space of the motor flows fully, the heat inside the motor is evenly distributed, and then it can be dissipated through the entire outer surface of the middle sleeve 201, thereby improving the heat dissipation efficiency.

[0035] Further:

[0036] A shield 601 is rotated on the outer ring of the fan blade 602, and a spring I 603 is provided between the shield 601 and the rear blocking plate 401, so that the outer end of the shield 601 is pressed against the rear end of the inner sleeve 301.

[0037] The inner and outer spaces of the inner sleeve 301 are isolated by the protective cover 601, so that when the fan blades 602 rotate, the air in the inner space of the inner sleeve 301 is sucked and blown to the rear blocking plate 401, then flows to the outer space of the inner sleeve 301, and then returns to the inner sleeve 301 through the front blocking plate 202, forming a sufficient flow of air.

[0038] Further:

[0039] By providing a guide edge 402 on the side of the rear blocking plate 401 close to the fan blade 602 , the air blown to the rear blocking plate 401 by the fan blade 602 can be guided by the guide edge 402 to quickly flow to the ventilation slot 302 .

[0040] like Figure 7 and9 As shown:

[0041] A groove 502 is formed at the rear end of the central shaft 501 and extends forward. The groove 502 is connected to the interior of the shield 601 through a plurality of through holes 503 provided on the central shaft 501 .

[0042] By setting the groove 502 and the through hole 503, the internal space of the motor is connected with the air of the external environment, so that when the fan blade 602 rotates to suck the air in the space of the inner sleeve 301, the external air can enter through the groove 502 and the through hole 503, forming a supplement to the air and then forming an exchange of internal and external air, further improving the heat dissipation efficiency.

[0043] Further:

[0044] By providing a dustproof net 702 in the groove 502, dust is prevented from entering the interior of the motor;

[0045] at the same time:

[0046] The dustproof net 702 is provided with a control sleeve 701, and two sliders 704 are symmetrically provided on the outer surface of the control sleeve 701. The inner surface of the groove 502 is symmetrically provided with two guide grooves 504. The two sliders 704 slide in the two guide grooves 504 respectively to lock the dustproof net 702.

[0047] The guide groove 504 includes an axial groove 504a extending inward, a circumferential groove 504b connected to the inner end of the axial groove 504a, and a locking groove 504c arranged at the other end of the circumferential groove 504b. A spring II 703 is arranged between the dustproof net 702 and the inner end of the groove 502.

[0048] When replacing the dust screen 702, the dust screen 702 is inserted into the groove 502 through the control sleeve 701, and the two sliders 704 are respectively aligned with the two axial grooves 504a, until the two sliders 704 slide into the circumferential groove 504b, at this time, the dust screen 702 squeezes the spring II 703, and then the control sleeve 701 is rotated to make the two sliders 704 slide in the circumferential groove 504b respectively, until they slide to the end of the circumferential groove 504b, and then the control sleeve 701 is released, and the elastic force of the spring II 703 will push the dust screen 702 to drive the control sleeve 701 to slide outward, and then the two sliders 704 slide into the two locking grooves 504c respectively to complete the locking;

[0049] This enables the dust screen 702 to be quickly disassembled, installed and replaced.

[0050] Further:

[0051] The outer surface of the middle sleeve 201 is provided with a spiral groove 204 , and the outer surface of the middle sleeve 201 is sleeved with an outer sleeve 101 , and the outer sleeve 101 is provided with two connecting pipes 102 .

[0052] The circulation system is connected with the two connecting pipes 102, so that the coolant can flow in a spiral circulation in the spiral groove 204, and then fully cool the middle sleeve 201, thereby cooperating with the full flow of air inside the motor, and further forming sufficient heat dissipation of the motor.

[0053] Further:

[0054] A base 103 is fixed on the outer shell 101 .
