[0024] It should be noted that the impurities in the water tank 1 are broken and intercepted by the anti-blocking mechanism 9, and the filter 6 is cleaned in time to prevent the impurities from directly accumulating and sticking to the filter 6 or the sewage pipe 4, which causes the staff to frequently remove the bolts to replace and maintain the filter 6, thereby improving work efficiency.

[0025] See also Figure 1-3 In order to further improve the working efficiency of the device, the anti-blocking mechanism 9 in this embodiment includes a driving assembly, a stirring assembly is provided on the driving assembly, and a cleaning assembly is provided on the driving assembly. The driving assembly includes a motor 901 fixed to the back of the connecting plate 8, and the output shaft of the motor 901 is fixed with a worm 902 having one end penetrating into the inner cavity of the connecting plate 8 and rotatably connected to its front side wall through a bearing. The front and rear sides of the outer surface of the worm 902 are fixed with threaded strips with opposite thread directions, so as to drive the two worm wheels 906 to rotate in opposite directions. The driving assembly also includes a threaded rod 903 rotatably connected between the front and rear sides of the inner cavity of the connecting plate 8 through a bearing, and the outer surfaces of the threaded rod 903 and the worm 902 are fixed with transmission wheels 904, and a conveyor belt 905 is transmission-connected between the two transmission wheels 904. By starting the motor 901 to drive the worm 902 and the transmission wheel 904 to rotate, the threaded rod 903 can be driven to rotate through the conveyor belt 905, thereby providing a power source for the stirring assembly and the cleaning assembly.

[0026] Among them, the stirring assembly includes two worm wheels 906 meshing with the worm 902, and the inner wall of the axis of the worm wheel 906 is fixed with a rotating rod 907 at one end which is rotatably connected to the inner top wall of the connecting plate 8 through a bearing and the other end of which passes through the interior of water tank No. 1. The bottom of the rotating rod 907 is rotatably connected to the inner bottom wall of the water tank 1 through a bearing, and a rotating hole is opened on the upper surface of the water tank 1. The rotating hole and the rotating rod 907 are rotatably connected, so that the rotating rod 907 can be more stable when it is rotated under force. A plurality of scrapers 908 are fixed to the outer surface of the rotating rod 907, and the scrapers 908 are driven to rotate by the rotating rod 907, thereby crushing the impurities entering the water tank 1.

[0027] At the same time, the cleaning component includes a moving block 909 threadedly connected to the outer surface of the threaded rod 903, and a moving hole is provided on the upper surface of the water tank 1. The moving hole and the moving block 909 are slidably connected. The cross-section of the moving block 909 is convex. A cleaning brush 910 that fits the filter screen 6 is fixed to the bottom of the moving block 909, and a guide slider 911 is fixed to the right end of the moving block 909. A guide groove 912 is provided on the inner right side wall of the connecting plate 8. The guide groove 912 and the guide slider 911 are slidably connected. The cross-sections of the guide groove 912 and the guide slider 911 are both T-shaped. The guide slider 911 moves along the guide groove 912 as the moving block 909 moves, providing guidance for the movement of the moving block 909, and driving the cleaning brush 910 to clean the filter screen 6 through the moving block 909.

[0028] It should be noted that the driving component provides power to the stirring component and the cleaning component, thereby intercepting and crushing impurities in the water tank 1 to prevent them from clogging the sewage pipe 4 and the filter 6, thereby ensuring the normal operation of the device.

[0029] The working principle of the above embodiment is:

[0030] (1) When water flows into the water tank 1 through the water inlet pipe 2, the worm 902 and the transmission wheel 904 are driven to rotate by starting the motor 901, so that the threaded rod 903 can be driven to rotate through the conveyor belt 905, and the rotation of the worm 902 drives the worm wheel 906 and the rotating rod 907 to rotate. Since the front and rear sides of the outer surface of the worm 902 are fixed with thread strips with opposite thread directions, the two worm wheels 906 can drive the two rotating rods 907 to rotate in opposite directions, and then drive multiple scrapers 908 to rotate, so as to break and intercept larger impurities entering the water tank 1, so as to prevent the larger impurities from directly accumulating and sticking to the filter screen 6 or accumulating and clogging in the sewage pipe 4, thereby further improving the working efficiency of the device.

[0031] (2) At the same time, the rotation of the threaded rod 903 can drive the moving block 909 to move. At this time, the guide slider 911 moves along the guide slot 912 with the movement of the moving block 909, providing a guide for the movement of the moving block 909. The moving block 909 drives the cleaning brush 910 to clean the filter 6, and the impurities on the filter 6 can be further cleaned and swept away, so that the impurities can be collected through the sewage pipe 4. Through the cooperation of the above components, the device is convenient for intercepting and crushing the impurities entering the water tank 1 to avoid clogging the sewage pipe 4 and the filter 6, thereby affecting the use effect of the device. It also further cleans the filter 6 to avoid it being blocked by larger impurities, which causes the staff to frequently dismantle the bolts to replace it, which is more time-saving and labor-saving, and also reduces maintenance costs.
