[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figures 1-4 Shown:

[0026] Example 1:

[0027] An automatic cleaning device for preventing material jamming in a discharge valve is installed on one side of the discharge valve body 1, comprising:

[0028] Mounting frame 2 is inserted and connected to one side of the unloading valve body 1;

[0029] The swing arm 4 is hinged to the inner wall at the bottom of the mounting frame 2;

[0030] Cleaning brush 3 is located on one side of the swing arm 4, and a connecting component 6 for fixing the position of cleaning brush 3 is provided at the connection between cleaning brush 3 and swing arm 4.

[0031] The pushing component 5 includes a second rotating arm 503 hinged to the inner wall of one side of the mounting frame 2. A first rotating arm 501 is provided on one side of the second rotating arm 503. The first rotating arm 501 is hinged to one side of the swing arm 4. Mounting grooves 502 are provided on the opposite side of the second rotating arm 503 and the first rotating arm 501. Torsion springs 504 are inserted and connected inside the mounting grooves 502. A rotating component is provided at the connection between the first rotating arm 501 and the second rotating arm 503.

[0032] It should be noted that the first rotating arm 501 and the second rotating arm 503 are respectively hinged to the swing arm 4 and the mounting frame 2, so that the first rotating arm 501 and the second rotating arm 503 can rotate on one side of the swing arm 4 and the mounting frame 2 respectively. A rotating component is provided at the connection between the first rotating arm 501 and the second rotating arm 503, so that the first rotating arm 501 can rotate on the second rotating arm 503. In use, the impeller is driven to rotate by the motor. When the swing arm 4 moves, it drives the first rotating arm 501 to move. At the same time, the first rotating arm 501 drives the second rotating arm 503 to rotate, and at the same time, it drives the torsion spring 504 to deform. When the push on the swing arm 4 is lost, the torsion spring 504 restores its deformation to drive the swing arm 4 to reset, thereby driving the cleaning brush 3 at one end to brush on the impeller, thereby cleaning the impeller.

[0033] Specifically, the rotating component includes a connecting rod 505 that is inserted and connected to one end of the first rotating arm 501 and the second rotating arm 503. Both ends of the connecting rod 505 are fixedly connected to a limiting disc 506 for restricting the movement of the first rotating arm 501 and the second rotating arm 503.

[0034] It should be noted that a connecting rod 505 is inserted and connected at the connection between the first rotating arm 501 and the second rotating arm 503, and two limiting discs 506 are respectively set on both sides of the first rotating arm 501 and the second rotating arm 503. The movement of the first rotating arm 501 and the second rotating arm 503 is restricted by the two limiting discs 506, thereby restricting the movement of the first rotating arm 501 and the second rotating arm 503, and allowing the first rotating arm 501 to rotate at one end of the second rotating arm 503.

[0035] Specifically, the connecting component 6 includes a connecting block 601 disposed on one side of the cleaning brush 3, a fixing block 603 fixedly connected to one side of the swing arm 4, a connecting groove 602 opened on one side of the connecting block 601, the fixing block 603 being inserted into the inside of the connecting groove 602, and a snap-fit ​​7 provided at the connection between the connecting block 601 and the fixing block 603, the snap-fit ​​7 being used to fix the position of the cleaning brush 3.

[0036] It should be noted that the fixed block 603 is adapted to the opening of the connecting groove 602, so that the connecting block 601 can be sleeved on the outer wall of the fixed block 603 through the connecting groove 602. The fixed block 603 restricts the movement direction of the connecting block 601, and the locking member 7 fixes the fixed block 603 and the connecting block 601 together.

[0037] Example 2:

[0038] Snap-fit ​​component 7 is used in the cleaning device of Embodiment 1;

[0039] Specifically, the snap-fit ​​component 7 includes a snap-fit ​​block 701 that is inserted into the top of the fixing block 603. The inner wall of the top of the connecting groove 602 has a snap-fit ​​hole 702. The snap-fit ​​block 701 is inserted into the inside of the snap-fit ​​hole 702. The bottom end of the snap-fit ​​block 701 is fixedly connected to a push plate 704. The bottom end of the push plate 704 is fixedly connected to an elastic block 703 for pushing the push plate 704. The middle part of the fixing block 603 has a cavity 705. The push plate 704 is inserted into the inside of the cavity 705. The elastic block 703 is fixedly connected to the inner wall of the bottom end of the cavity 705.

[0040] It should be noted that the cavity 705 is adapted to the push plate 704, allowing the push plate 704 to slide inside the cavity 705; the elastic block 703 is made of rubber and is used to push the push plate 704 towards the locking block 701 during use, thereby preventing the locking block 701 from wobbling during use; when it is necessary to fix the cleaning brush 3 in place, first move the connecting block 601 at the bottom of the cleaning brush 3 towards the fixing block 603, so that the connecting block 601 passes through the connecting groove. 602 is fitted onto the fixing block 603. When the connecting block 601 moves to fit against the locking block 701, the locking block 701 is pressed against one side of the push plate 704, causing the locking block 701 to separate from the connecting block 601. The position of the connecting block 601 continues to move. When the connecting block 601 is moved to the point where the locking hole 702 in the middle is aligned with the locking block 701, the locking block 701 is pushed into the interior of the locking hole 702 by the elastic block 703, and the position of the connecting block 601 is fixed by the locking block 701, thereby fixing the position of the cleaning brush 3 by the connecting block 601.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
