However, the device in the above application does not have a structure for quickly disassembling and assembling the heat dissipation component during use, which brings unnecessary trouble to the operator.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original AC motor. Summary of the invention

[0018] See also Figure 1-Figure 7 The present invention provides the following technical solution: an AC motor component: Embodiment 1: The external frame 12 can be installed quickly, which is convenient for the operator to work. Figure 5-Figure 7 As shown: It includes an external frame 12 and a fixing block 13. A lower connecting rod 14 is fixedly connected to the lower surface of the external frame 12. A fan is rotatably arranged inside the external frame 12. The left side of the lower connecting rod 14 is an inverted "L" structure.

[0020] When docking the heat dissipation component, the lower connecting rod 14 on the lower surface of the external frame 12 is inserted into the fixed block 13. At this time, the lower connecting rod 14 will push the card block 16 to move the card block 16 in the direction of squeezing the reset spring 19. When the external frame 12 contacts the back side of the body 2, the card block 16 and the card slot 15 are in the same horizontal direction. At this time, the card block 16 enters the card slot 15 under the action of the reset spring 19, that is, the external frame 12 has been docked to the body 2, and the operation process is quick and convenient.

[0021] Embodiment 2: The external frame 12 can be quickly disassembled to facilitate the operator to clean the internal structure. Figure 7 As shown: A return spring 19 having an elastic return function is fixedly connected to the side surface of the connecting plate 18 , and the other side of the return spring 19 is fixedly connected to the surface of the clamping block 16 .

[0022] During the movement of the block 16, the cross bar 17 enables the block 16 to move only in the horizontal direction, thereby ensuring stability. When the operator needs to remove the lower connecting rod 14, the block 16 can be pulled to move the end of the block 16 out of the slot 15. At this time, the lower connecting rod 14 and the fixing block 13 are not in an engaged state, and the operator can remove the lower connecting rod 14 and the external frame 12 in a direction away from the body 2, that is, the operator can quickly remove the external frame 12, which is convenient for the operator to clean the fan.

[0023] Embodiment 3: Different from Embodiment 2, the fixing plate 3 and the pressure plate 4 are provided, so that the body 2 can be well protected. Figure 1-Figure 4 As shown: An AC motor comprises an auxiliary plate 1, a pressure plate 4 and a limiting rod 5, wherein the back of the auxiliary plate 1 is fixedly connected to an organism 2, and the surface of the auxiliary plate 1 is fixedly connected to a fixing plate 3, and the fixing plate 3 is a through structure, and the upper surface of the fixing plate 3 is fixedly connected to a fixing block 13; The side of the pressure plate 4 is fixedly connected with a docking block 7, and the pressure plate 4 is symmetrically distributed about the center of the fixed plate 3. The limit rod 5 is fixedly connected to the inner wall of the fixed plate 3, and the surface of the limit rod 5 is sleeved with a slider 11, and the surface of the slider 11 is concave; An AC motor further comprising: A long pin 9 is fixedly connected to the inner wall of the slider 11, and a connecting rod 10 is sleeved on the surface of the long pin 9. A connecting shaft 8 is fixedly connected to the side of the docking block 7, and the docking block 7 is symmetrically distributed about the center of the connecting shaft 8, and a connecting rod 10 is sleeved on the surface of the connecting shaft 8.

[0025] During use, the body 2 will be protected by the fixed plate 3 on the surface of the auxiliary plate 1. At the same time, when the pressure plate 4 is subjected to pressure, the pressure plate 4 will drive the docking block 7 and the connecting rod 10 to move (the connecting rod 10 will rotate on the connecting shaft 8). When the connecting rod 10 moves, it will push the slider 11 through the long pin 9. At this time, the slider 11 slides on the limit rod 5, and then the connecting spring 6 will be squeezed, and then the connecting spring 6 plays a buffering role, that is, the fixed plate 3 and the pressure plate 4 play a buffering and protective role, so that the service life of the body 2 is extended, and during use, the limit rod 5 limits the direction of the slider 11 to ensure the stability of the movement of the slider 11.

[0026] During the use of the present invention, the machine body will be protected by the fixed plate on the surface of the auxiliary plate. At the same time, when the pressure plate is subjected to pressure, the pressure plate will drive the docking block and the connecting rod to move. When the connecting rod moves, it will push the slider to slide on the limit rod. At this time, the connecting spring will be squeezed, and then the connecting spring plays a buffering role, that is, the fixed plate and the pressure plate play a buffering and protective role, so that the service life of the machine body is extended. Further, during use, the limit rod limits the direction of the slider to ensure the stability of the slider movement. When docking the heat dissipation component, the lower connecting rod on the lower surface of the external frame is inserted into the fixed block. At this time, the lower connecting rod will push the card block to move the card block in the direction of squeezing the reset spring. When the external frame contacts the rear side of the machine body, the card block and the card slot are in the same horizontal direction. At this time, the card block enters the card slot under the action of the reset spring, that is, the external frame has been docked to the machine body, and the operation process is quick and convenient. Furthermore, during the movement of the card block, the cross bar allows the card block to move only in the horizontal direction, ensuring stability. At the same time, the connecting plate limits the moving distance of the card block, and the cooperation between the connecting plate and the card block also allows the reset spring to work better. When the operator needs to remove the lower connecting rod, the card block can be pulled to move the end of the card block out of the card slot. At this time, the lower connecting rod and the fixed block are not in a locked state, and then the operator can remove the lower connecting rod and the external frame in a direction away from the body, that is, the operator can quickly remove the external frame, which is convenient for the operator to clean the fan.
