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.

[0022] like Figure 1-4 As shown, this utility model provides a technical solution:

[0023] A sweeper water tank includes a water tank body 1. A water-blocking mechanism is provided inside the water tank body 1, including a water-blocking shell 7. The water-blocking shell 7 is located at the lower center of the inner side of the water tank body 1. A flow channel is provided between the water-blocking shell 7 and the upper end of the water tank body 1. A connecting groove 8 is penetrated at the bottom end of the water-blocking shell 7. A water-replenishing mechanism is provided on the right side of the water tank body 1, including a water-replenishing inlet 4. The water-replenishing inlet 4 is located at the center of the right side of the water tank body 1. A movable sleeve 5 is threadedly connected to the right side of the water tank body 1 and outside the water-replenishing inlet 4. A plug 6 matching the water-replenishing inlet 4 is provided on the left side of the movable sleeve 5. A tank cover 2 is threadedly connected to the left side of the water tank body 1. A cone 3 is provided on the left side inside the tank cover 2. An opening and closing mechanism is provided in front of the cone 3. The opening and closing mechanism includes a rod groove 9. The rod groove 9 is opened in the middle of the right side of the cone 3. A push rod 10 is movably connected inside the rod groove 9. A plug 11 is provided on the left side of the push rod 10. A fixing member 12 is provided in the middle of the push rod 10. A spring 13 is provided between the fixing member 12 and the cone 3 and outside the push rod 10. Several filter screens 14 are provided at equal arcs on the outer wall of the cone 3. A threaded groove 15 is opened on the outer left side of the box cover 2. Two outer seals 16 are arranged side by side on the outer left side of the box cover 2 and close to the right side of the threaded groove 15. An inner seal 17 is provided on the inner left side of the box cover 2 and close to the outer side of the plug 11. Several paddles 18 are provided at equal arcs on the outer right side of the box cover 2.

[0024] In this embodiment, by setting a water-blocking mechanism, the water-blocking shell 7 can block the waves generated by the reciprocating motion inside the water tank, forming a locally stable water storage pool inside. Combined with the function of the flow channel and the connecting groove 8, even when the water in the water tank fluctuates due to the reciprocating pushing and pulling operation of the sweeper, a stable water source can be provided to the water outlet, thereby ensuring that the water output at the water inlet of the sweeper is uniform, avoiding the problem of uneven water output or temporary water shortage caused by waves, and improving the cleaning effect of the sweeper.

[0025] A filter screen 14 is installed on the outer wall of the cone 3 to filter the water flowing out of the water tank, intercept impurities in the water, prevent impurities from entering the water inlet of the sweeper, avoid clogging the water system of the sweeper, extend the service life of the sweeper, and ensure the normal operation of the sweeper.

[0026] The cover 2 is connected to the water tank body 1 by a thread, and a lever 18 is set on the outside of the cover 2. When it is necessary to clean the impurities trapped on the outside of the filter screen 14, the cover 2 can be easily removed from the water inlet of the sweeper, and then the cover 2 can be twisted by lever 18 to separate it from the water tank body 1, so as to manually clean the dirt on the surface of the filter screen 14. The operation is simple and convenient, which helps to maintain the cleanliness of the filter screen 14 and the filtration effect.

[0027] An outer seal 16 is provided at the connection between the tank cover 2 and the water tank body 1, and an inner seal 17 is provided on the outside of the tank cover 2 near the plug 11. This can effectively prevent water leakage in the water tank, ensure the water tank's sealing performance, and improve the water tank's reliability.

[0028] Working principle: During installation, the tank cover 2 at one end of the water tank body 1 is threaded to the water inlet of the sweeper via the outer seal 16. After installation, the pin at the water inlet will push the plug 11 towards the cone 3, and drive the fixing part 12 to compress the spring 13. At this time, the plug 11 separates from the inner seal 17, opening the water outlet. The water inside the water tank body 1 passes through the filter screen 14 and enters the water inlet of the sweeper. When the sweeper reciprocates horizontally, the water inside the water tank body 1 moves back and forth, forming waves. The water baffle 7 will block the water flow back from the tank cover 2 and form a locally stable water reservoir inside the water baffle 7. The top of the water-blocking shell 7 is equipped with a flow channel. Waves on the right side of the water-blocking shell 7 can climb over the slope and enter the left side, continuously replenishing the water storage tank on the left. When the waves formed on the right side cannot climb over the water-blocking shell 7, the water will flow into the left side through the connecting groove 8. This can provide a stable water source for the outlet of the tank cover 2. When it is necessary to clean the impurities trapped on the outside of the filter screen 14, the tank cover 2 is removed from the water inlet of the sweeper. At this time, the spring 13 will control the plug 11 to reset and block the outlet. Then, the tank cover 2 is twisted by the lever 18 to separate the water tank body 1 from the tank cover 2. Then the dirt on the surface of the filter screen 14 can be manually cleaned.
