[0020] See also Figure 1-3The utility model provides a technical solution: a rotating motor that is easy to clean, including a motor housing 1, an output shaft 2 and a wind cover 3. The side wall of the motor housing 1 is provided with a plurality of card slots 8 and arranged in a circular array along the motor housing 1. The inner wall of the wind cover 3 is provided with a plurality of card block slots 10 corresponding to the card slots 8. A card block 9 for being inserted into the card slot 8 is provided in the card block slot 10. A first reset groove 11 is provided in the inner wall of the card block slot 10 close to the output shaft 2. A reset mechanism for preventing the card block 9 from sliding out of the card block slot 10 is provided in the first reset groove 11. The inner wall of the card block slot 10 far from the first reset groove 11 is connected to a transmission mechanism. A movable rod groove 14 is provided in the transmission rod groove 14 with a transmission rod 15 for controlling the card block 9 to move out of the card block groove 10, a control rod groove 19 is provided in the inner wall of the transmission rod groove 14 away from the card block 9, a control rod 20 is slidably provided in the control rod groove 19 to move the transmission rod 15, each control rod groove 19 is connected to the middle position of the wind hood 3, a pressure column groove 21 is provided on the middle inner wall of the control rod groove 19, a pressure column 22 for controlling the movement of the control rod 20 is provided in the pressure column groove 21, a knob 25 for controlling the movement of the pressure column 22 is provided on the wind hood 3, and a ventilation net 4 is provided on the wind hood 3 between each control rod groove 19.

[0021] Specifically, the end of the block 9 that abuts against the transmission rod 15 is an inclined surface, the end of the transmission rod 15 that abuts against the control rod 20 is an inclined surface, and the end of the control rod 20 that abuts against the pressure column 22 is an inclined surface. The control rod 20 moves to act on the inclined surface of the transmission rod 15, and the transmission rod 15 is forced to move and act on the inclined surface of the block 9, so that the block 9 is forced to slide out of the block slot 10 and get stuck in the slot 8, thereby limiting the wind hood 3.

[0022] Specifically, the reset mechanism includes a first reset block 13 and a first reset spring 12. The inner wall of the first reset groove 11 close to the card slot 8 is fixedly connected to the first reset spring 12. The first reset spring 12 is fixedly connected to the first reset block 13. The first reset block 13 is slidably arranged in the first reset groove 11 and is fixedly connected to the side wall of the card block 9. The elastic force of the first reset spring 12 ensures that the card block 9 does not slide out of the card block groove 10 and affect the installation of the wind hood 3.

[0023] Specifically, a second reset groove 16 is opened on the inner wall of the transmission rod groove 14, and a second reset spring 17 is fixedly provided on the inner wall of the second reset groove 16 near the block 9. The second reset spring 17 is fixedly connected to a second reset block 18 which is fixedly connected to the side wall of the transmission rod 15 and is slidably arranged in the second reset groove 16. Through the elastic force of the second reset spring 17, the transmission rod 15 can be automatically reset when not affected by the control rod 20, so as to prevent the transmission rod 15 from exerting force on the block 9 under its own gravity, causing the block 9 to move out of the block groove 10.

[0024] Specifically, a threaded groove 23 is provided at one end of the pressure column 22 located in the pressure column groove 21, and a screw 24 is threadedly connected to the threaded groove 23. The screw 24 passes through the wind hood 3 and is rotatably connected to the wind hood 3 through a bearing. The knob 25 is fixedly connected to the end of the screw 24 located outside the wind hood 3. Turning the knob 25 drives the screw 24 to rotate, and the threaded connection between the screw 24 and the threaded groove 23 allows the pressure column 22 to slide in the pressure column groove 21, thereby applying force to the inclined surface of the control rod 20.

[0025] Specifically, a retaining ring 7 is provided on the fixed ring of the motor housing 1, a fillet 6 is fixedly provided on the outer wall of the motor housing 1 on one side of the retaining ring 7, and multiple fillets 6 are evenly arranged along the outer wall of the motor housing 1, and a groove 5 for the fillet 6 to slide into is opened on the inner wall of the wind hood 3 corresponding to the fillet 6. When installing the wind hood 3, the groove 5 is aligned with the fillet 6 and slides in. When the wind hood 3 and the retaining ring 7 are against each other, the block 9 is opposite to the groove 8, thereby facilitating the installation of the wind hood 3.

[0026] A specific application example of this embodiment is:

[0027] When the device is in use, when installing the wind shield 3, the embedded groove 5 is aligned with the embedded strip 6 and slid in. When the wind shield 3 and the retaining ring 7 are against each other, the block 9 and the slot 8 are directly opposite each other. The knob 25 is turned to drive the screw rod 24 to rotate. The screw rod 24 is connected with the threaded groove 23 to make the pressure column 22 slide in the pressure column groove 21, thereby applying force to the inclined surface of the control rod 20, so that the control rod 20 slides to the inclined surface of the transmission rod 15. The transmission rod 15 is forced to move to the inclined surface of the block 9 and drive the second reset block 18 to compress the second reset spring 17. The block 9 is forced to slide out of the block slot 10 and into the block slot 8, driving the first reset block 13 to compress the first reset spring 12, and the wind hood 3 can be installed. When removing the wind hood 3, the knob 25 is rotated in the opposite direction to move the pressure column 22 to lose the force on the control rod 20, and the transmission rod 15 is reset under the elastic force of the second reset spring 17. Under the elastic force of the first reset spring 12, the block 9 slides out of the slot 8 and into the block slot 10, so that the wind hood 3 loses its limit and can be removed from the motor housing 1. The operation is convenient, and no parts need to be removed to avoid loss.
