Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1-4 The present application provides a wet spraying trolley, comprising a main body 1, a water tank 2 is provided on the main body, and a water inlet 3 connected to the interior of the water tank is provided on the top surface of the water tank, a filter chamber 4 is provided in the water tank, and a partition 5 is provided in the filter chamber, and the partition divides the filter chamber into a main filter chamber and a secondary filter chamber, and a center hole is provided on the partition, and a filter box 6 is provided in the main filter chamber, wherein the filter box can be cylindrical or rectangular, and a buffer structure is provided in the secondary filter chamber, one end of the filter box is against the inner wall of the main filter chamber, and the other end passes through the center hole and is against the buffer structure; there is a gap between the top surface of the filter box and the top surface of the main filter chamber to form a first main filter chamber, and the first main filter chamber is connected to the water inlet, and there is a gap between the bottom surface of the filter box and the bottom surface of the main filter chamber to form a second Main filter chamber; the second main filter chamber is provided with an isolation block 7, which divides the second main filter chamber into an auxiliary chamber 8 and a drainage chamber 9, the drainage chamber is arranged close to the partition relative to the auxiliary chamber, and the bottom end of the drainage chamber is provided with a drainage hole 10 connected to the inside of the water tank; the top surface of the filter box is provided with a first filter screen 11, and the bottom surface of the filter box is provided with a second filter screen 12 and a third filter screen 13, the second filter screen is located in the auxiliary chamber, and the third filter screen is located in the drainage chamber; the bottom end of the isolation block is connected to the bottom surface of the second main filter chamber, and a piston 14 is fixed to the top of the filter box, which divides the first main filter chamber into a water inlet chamber 15 and an intermediate chamber 16, the intermediate chamber is connected to the inside of the filter box, the water inlet chamber is connected to the water inlet, and the first filter screen is located in the water inlet chamber.

[0022] When the above-mentioned wetting trolley is taking water, the water inlet is connected to the water pipe, and the water enters the water inlet chamber through the water pipe, passes through the first filter screen and the third filter screen into the drainage chamber, and is finally discharged into the water tank through the drainage hole; when the first filter screen is blocked, the piston is pushed to the right under the pressure of the water at the water inlet, driving the filter box to move to the right as a whole, and the water inlet chamber and the auxiliary chamber are connected. At this time, the water can pass through the second filter screen and the third filter screen into the drainage chamber, and finally be discharged into the water tank through the drainage hole; when the wetting trolley is taking water, the second filter screen can assist in filtration, so that water can continue to be stored even after the first filter screen is blocked by debris.

[0023] As a preferred embodiment, the buffer structure includes a accommodating chamber 17, which is located in the auxiliary filter chamber 18 and is connected to the center hole. A spring 19 is provided in the accommodating chamber, and the spring is against the filter box; a through hole 20 is provided on the bottom surface of the accommodating chamber and is connected to the auxiliary filter chamber, and a bypass pipe 21 is connected to the water inlet, one end of the bypass pipe is connected to the water inlet, and the other end is connected to the auxiliary filter chamber. A one-way valve 22 is provided on the bypass pipe, and when the one-way valve is open, the water at the water inlet flows to the auxiliary filter chamber. In this structure, when the second filter screen is clogged, the filter box continues to compress the spring, allowing the third filter screen to enter the holding chamber and the second filter screen to enter the drainage chamber. During this process, the isolation block scrapes off the attached debris on the second filter screen. As the water pressure continues to increase, the one-way valve opens, and the water at the water inlet enters the auxiliary filter chamber through the bypass pipe, passes through the through hole, the third filter screen and the second filter screen into the drainage chamber, and finally is discharged into the water tank through the drainage hole. At the same time, since the water pressure at the water inlet is released, under the action of the restoring force of the spring; the filter box moves to the left, and the water flows through the second filter screen and the third filter screen into the drainage chamber again while the one-way valve is closed. When the second filter screen is clogged again, the above action is repeated again, and so on.

[0024] As a preferred embodiment, a scraper 23 is fixed to the top surface of the water inlet chamber, and is provided with a water hole 24. The scraper is positioned relative to the first filter and close to the piston. By providing the scraper, as the filter box moves to the right, the scraper can scrape off most debris on the surface of the first filter, thereby allowing the first filter to fully or partially restore its filtering function. When the one-way valve is open, the restoring force of the spring can restore the filter box to its original state. This allows the first and second filters to continue to move to the right only after they become blocked again in the event of a secondary blockage, thereby extending the time it takes for the filters to become blocked.

[0025] In actual production, the width of the second filter and the third filter is preferably greater than the width of the isolation block, wherein the width is based on Figure 3The left and right directions are used as the reference. To facilitate water inlet, the top surface of the water tank is provided with an exhaust hole 25 so that the gas inside the water tank can be discharged along the exhaust hole when the water tank is filled with water. Of course, the water tank is also provided with a water spray pipe 26, and a nozzle 27 is provided at the end of the water spray pipe not connected to the water tank. The water spray pipe is provided with a suction pump or a water pump connected to the water spray pipe is provided in the water tank to lift the water in the water tank to the nozzle for spraying. Of course, it is also possible to set up a continuous auxiliary nozzle action to automatically control the operation of the nozzle. This is well known to those skilled in the art and will not be described in detail here.
