[0029] According to the overall structure of the device, the water outlet end of the valve body 1 is installed at the corresponding position of the cleaning machine, and then the threaded barrel 15 is threadedly connected to the water inlet end of the valve body 1. When the threaded connection is inconvenient to rotate, the hexagonal rod 18 is inserted into the hexagonal groove 17 to assist the threaded barrel 15 in rotational installation. After the installation is completed, the hexagonal rod 18 is pulled out. When the valve body 1 needs to be switched, the sleeve 11 is driven to rotate by the driving motor 10. Since the limit strip of the limit block on the inner wall of the inner cavity of the sleeve 11 is inserted into the limit groove on the inner wall of the inner cavity of the sleeve 11, the movable rod 12 It can rotate together with the sleeve 11, so that the gear 2 13 on the movable rod 12 rotates, to drive the gear 1 8 meshing therewith to rotate, so that the hand wheel 5 can rotate automatically, and there is no need to use hands or other additional tools to switch. When the gear 1 8 rotates, the valve stem 4 will change its height. Due to the arrangement of the bearing 19 and the connecting rod 14, the movable rod 12 can also change its height with the valve stem 4 without affecting the rotation of the valve stem 4 and the movable rod 12, so that the gear 1 8 and the gear 2 13 can always remain meshed.

[0030] like Figure 2 As shown, a valve flap 2 is fixedly connected to the bottom surface of the valve stem 4, and the valve flap 2 is slightly larger than the opening formed between the baffle plate 1 6 and the baffle plate 2 7.

[0031] By setting the valve flap 2, when the valve stem 4 moves up and down, the valve flap 2 can be driven to press against or no longer press against the opening between the baffle plate 1 6 and the baffle plate 2 7 to perform opening and closing.

[0032] like Figure 1-3As shown, the auxiliary switch assembly includes a mounting frame 9, a drive motor 10, a sleeve 11, a movable rod 12 and a gear 13. The mounting frame 9 is fixedly mounted on the side of the valve body 1, and the drive motor 10 is fixedly mounted on the inner wall of the mounting frame 9. The output end of the drive motor 10 is fixedly connected to the sleeve 11. The sleeve 11 has an inner cavity, and an opening is passed through the top surface. The top surface opening of the sleeve 11 is smaller than the inner cavity of the sleeve 11. Two limit grooves are arranged on the inner wall of the inner cavity of the sleeve 11. A limit block is placed in the inner cavity of the sleeve 11. The arc surface of the limit block of the sleeve 11 is fixedly connected to the limit strips at both ends, and the limit strips Insert the limiting groove of the inner cavity of the sleeve 11, one end of the movable rod 12 passes through the top opening of the sleeve 11 and is fixedly connected to the top surface of the limiting block of the inner cavity of the sleeve 11, and the arc surface of the movable rod 12 fits with the inner wall of the top opening of the sleeve 11, and the arc surface of the movable rod 12 is fixedly installed with gear 2 13, the middle end of the top surface of the handwheel 5 is fixedly connected with a connecting shaft, and the arc surface of the connecting shaft is fixedly connected with gear 1 8, gear 1 8 and gear 2 13 are meshed with each other, the arc surface of the connecting shaft of the handwheel 5 and the arc surface of the movable rod 12 are both fixedly sleeved with bearings 19, and the top surface of the outer ring of the bearing 19 is fixedly installed with a connecting rod 14.

[0033] By means of the mounting frame 9, driving motor 10, sleeve 11, movable rod 12, gear 2 13, gear 1 8, connecting rod 14 and bearing 19, when the hand wheel 5 needs to be rotated, the sleeve 11 is driven to rotate by the driving motor 10. Since the limiting strip of the limiting block on the inner wall of the inner cavity of the sleeve 11 is inserted into the limiting groove on the inner wall of the inner cavity of the sleeve 11, the movable rod 12 can rotate along with the sleeve 11, so that the gear 2 13 on the movable rod 12 rotates to drive the gear 1 8 meshing therewith to rotate, so that the hand wheel 5 can rotate automatically without the need to switch by hand or other additional tools. When the gear 1 8 rotates, the valve stem 4 will change in height. Due to the setting of the bearing 19 and the connecting rod 14, the movable rod 12 can also change in height along with the valve stem 4 without affecting the rotation of the valve stem 4 and the movable rod 12, so that the gear 1 8 and the gear 2 13 can always remain meshed.

[0034] like Figure 4-5 As shown, the impurity prevention component includes a threaded barrel 15 and a filter screen 16. The outer surface of the threaded barrel 15 is provided with threads, and the inner wall of the water inlet end of the valve body 1 is provided with threads. The threaded barrel 15 is threadedly connected to the water inlet end of the valve body 1. The threaded barrel 15 is hollow inside, and openings are provided at both ends. The filter screen 16 is fixedly installed on the inner wall of the threaded barrel 15. A hexagonal groove 17 is provided at one end of the front side of the threaded barrel 15, and a hexagonal rod 18 is inserted into the inner wall of the hexagonal groove 17.

[0035] By providing the threaded barrel 15, the filter screen 16, the hexagonal groove 17 and the hexagonal rod 18, when water enters the water inlet end of the valve body 1, the water will pass through the filter screen 16 to filter out impurities in the water, thereby preventing the impurities from entering the cleaning machine and affecting the cleaning quality of the cleaning machine. When installing or removing the threaded barrel 15, the hexagonal rod 18 can be inserted into the hexagonal groove 17, and then the hexagonal rod 18 can be held and rotated to allow the threaded barrel 15 to rotate. After the installation or removal is completed, the hexagonal rod 18 can be pulled out from the hexagonal groove 17 so that it does not affect the water inlet.

[0036] Working principle: install the water outlet end of the valve body 1 at the corresponding position of the cleaning machine, and then thread the threaded tube 15 to the water inlet end of the valve body 1. When the threaded connection is inconvenient to rotate, insert the hexagonal rod 18 into the hexagonal groove 17 to assist the threaded tube 15 in rotational installation. After the installation is completed, pull out the hexagonal rod 18. When the valve body 1 needs to be switched, the sleeve 11 is driven to rotate by the driving motor 10. Since the limit strip of the limit block on the inner wall of the inner cavity of the sleeve 11 is inserted into the limit groove on the inner wall of the inner cavity of the sleeve 11, the movable rod 12 can rotate with the sleeve 11, thereby rotating the gear 2 13 on the movable rod 12 to drive the gear 1 8 meshing with it to rotate, so that the handwheel 5 can rotate automatically.
