Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1

[0031] Please refer to Figure 1-8As shown in the figure, the present invention is a rapid heat dissipation device for a fan, including a housing 2 fixedly connected to a belt guard 1, a motor 3 is arranged on the belt guard 1, a movable groove 4 is opened in the front of the outer surface of the housing 2, a heat dissipation groove 5 is penetrated and opened in the rear of the outer surface of the housing 2, a sliding groove 6 is opened on the front surface of the housing 2, the sliding groove 6 is communicated with the movable groove 4, and an adjusting mechanism 7 is arranged on the housing 2; the adjusting mechanism 7 includes a baffle 701, a gear 702, a fixing plate 703 and heat dissipation fins 704. A pyramid plate 705 is fixedly connected to the baffle 701. When the heat discharged through the heat dissipation groove 5 blows towards the baffle 701, the pyramid plate 705 can play a role in guiding the heat, so as to facilitate the air flow, accelerate the heat flow between the baffle 701 and the heat dissipation groove 5, and improve the heat dissipation effect. A connecting arm 706 is fixedly connected to the baffle 701. The outer surface of the connecting arm 706 is adapted to the inside of the movable groove 4. A convex rod 707 is fixedly connected to the connecting arm 706. The gear 702 is rotatably connected to the housing 2 through a shaft rod 708. An arc groove 709 is penetrated and opened in the gear 702. The inside of the arc groove 709 is adapted to the outer surface of the convex rod 707. The fixing plate 703 is fixedly connected to the housing 2. A plug rod 711 is connected to the fixing plate 703 through a reset mechanism 710. The plug rod 711 is movably connected to the gear 702. A pull ring 712 is fixedly connected to one end of the plug rod 711. The heat dissipation fins 704 are arranged inside the housing 2. The heat dissipation fins 704 are in contact with the motor 3. By rotating the gear 702, the baffle 701 is driven to move, and the heat dissipation groove 5 is opened or closed by the baffle 701. When the baffle 701 blocks the heat dissipation groove 5, dust can be prevented from adhering to the motor 3, and the normal heat dissipation of the motor 3 is avoided due to the influence of dust. When the heat dissipation groove 5 is open, the heat dissipation fins 704 conduct heat to the outer shell of the motor 3, and the heat is dissipated through the heat dissipation groove 5, thereby effectively improving the normal heat dissipation of the motor 3.

[0032] The reset mechanism 710 includes a through hole 7101, a circular plate 7102 and a first spring 7103. The through hole 7101 is penetrated and opened on one side of the fixing plate 703.

The first spring 7103 is sleeved on the outer surface of the plug rod 711, and the first spring 7103 is located between the circular plate 7102 and the fixing plate 703. By the combined use of the through hole 7101, the circular plate 7102 and the first spring 7103, the plug rod 711 can be reset, which is beneficial to the plug rod 711 to fit with the gear 702. When the heat dissipation groove 5 is in an open state, the rotation of the gear 702 is prevented, and indirectly the baffle 701 is positioned, which is beneficial to the normal heat dissipation of the motor 3.

[0033] One end of the first spring 7103 is fixedly connected to one side of the fixed plate 703, and the other end of the first spring 7103 is fixedly connected to one side of the circular plate 7102.

[0035] The sliding assembly 8 includes a groove 81 which is opened on the first connecting plate 7041. A second spring 82 is fixedly connected in the groove 81 and is fixedly connected to the second connecting plate 7042. The inside of the groove 81 is adapted to the outer surface of the second connecting plate 7042. By providing the sliding assembly 8, when installing the housing 2, it is beneficial for the second connecting plate 7042 to better fit on the surface of the motor 3. When the motor 3 is working, it is beneficial for the heat on the surface of the motor 3 to be dissipated through the heat dissipation fins 704.

[0036] The size of the baffle 701 is larger than the size of the heat dissipation groove 5, and the outer surface of the pyramid plate 705 is adapted to the inside of the heat dissipation groove 5.

[0037] The insertion rod 711 is integrally formed by a first connecting rod 7111 and a second connecting rod 7112. The outer surface of the first connecting rod 7111 is adapted to the inside of the through hole 7101, and the second connecting rod 7112 is inserted into the tooth gap of the gear 702.

[0038] Embodiment 2

[0039] Based on Embodiment 1, refer to Figure 8 as shown

[0040] A cone 9 is fixedly connected to the front surface of the inner wall of the housing 2. There are several heat dissipation fins 704. By providing the cone 9, during the operation of the fan, the motor 3 dissipates part of the heat through the heat dissipation part on the motor 3. Under the guiding action of the cone 9, the heat can be discharged from the heat dissipation groove 5.

[0041] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0042] Working principle of the present invention: When the fan is working, by pulling the pull ring 712 to one side, the insertion rod 711, the circular plate 7102 and the first spring 7103 are driven to move to one side, so that the first connecting rod 7111 slides in the through hole 7101. Under the action of the circular plate 7102 and the fixed plate 703, the first spring 7103 is in a compressed state. Then, the second connecting rod 7112 is withdrawn from the tooth gap on the gear 702. Then, the gear 702 is rotated. Thus, under the combined use of the arc-shaped groove 709 and the convex rod 707, the connecting arm 706 slides in the movable groove 4, and the connecting arm 706 drives the baffle 701 to move, so that the baffle 701 moves away from the heat dissipation slot 5, and the heat dissipation slot 5 is in an open state. Then, the pull ring 712 is released, and the first spring 7103 returns to its original state, driving the first connecting rod 7111 and the second connecting rod 7112 to reset. Then, the second connecting rod 7112 is inserted into the tooth gap on the gear 702, thereby fixing the gear 702 to prevent the gear 702 from rotating, indirectly positioning the baffle 701, which is beneficial to the normal heat dissipation of the motor 3. The second connecting plate 7042 is in contact with the surface of the motor 3. When the motor 3 is working, some heat generated by the motor 3 is dissipated through the surface of the motor 3, and then these heat is conducted to the second connecting plate 7042. Then, the heat is conducted to the first connecting plate 7041. The first connecting plate 7041 is relatively close to the heat dissipation slot 5, which is beneficial to discharging the heat through the heat dissipation slot 5. Some heat generated by the motor 3 will also be dissipated through the heat dissipation part on the motor 3. These heat blows onto the cone 9. Then, the heat moves along the surface of the cone 9. Under the guiding action of the cone 9, the heat can be discharged from the heat dissipation slot 5. When the fan is not working, by pulling the pull ring 712, and then rotating the gear 702, through the cooperation of the arc-shaped groove 709 and the convex rod 707, the baffle 701 is made to fit on the surface of the housing 2, thereby closing the heat dissipation slot 5, which can prevent dust from adhering to the surface of the motor 3. Therefore, in summary, by rotating the gear 702, the baffle 701 is driven to move, and the baffle 701 is used to open or close the heat dissipation slot 5. When the baffle 701 blocks the heat dissipation slot 5, dust can be prevented from adhering to the motor 3, avoiding the influence of dust on the normal heat dissipation of the motor 3. When the heat dissipation slot 5 is open, the heat dissipation fins 704 are used to conduct heat to the outer shell of the motor 3, and the heat is dissipated through the heat dissipation slot 5, thereby effectively improving the normal heat dissipation of the motor 3.
