Claims

1. A vehicle-mounted water tank, comprising a hollow water tank body, a washing pump located at the bottom of the water tank body, and a water inlet protruding from the top surface of the water tank body, the water inlet being threadedly fitted with a protective cap, characterized in that: It is also equipped with a funnel device, which includes a funnel body made of rigid material. The opening end of the funnel body has an annular skirt edge, and the tail end of the funnel body is connected to a flexible hose. The funnel body is configured to be inserted into or pulled out of the water tank through the water inlet. The hose is placed in the inner cavity of the water tank. The annular skirt edge of the funnel body rests on the rim of the water inlet. The protective cover can cover the annular skirt edge of the funnel body. When the protective cover is tightened on the water inlet, the annular skirt edge is pressed against the rim of the water inlet.

2. The on-board water storage tank of claim 1, wherein: The funnel body is connected to the large end of the annular skirt edge, which is formed with an annular straight cylindrical part, which fits and conforms to the inner wall of the water inlet.

3. The on-board water storage tank of claim 1 or 2, wherein: The vehicle-mounted water tank has two water inlets, one of which has a larger diameter than the other, and the funnel device is installed on the larger diameter water inlet.

4. The on-board water storage tank of claim 3, wherein: The small-diameter water inlet is equipped with an optional external filling device. The external filling device includes a bendable extension tube, an inner connector connected to the inner end of the extension tube, and a water inlet component connected to the outer end of the extension tube. The inner connector is sealed in the small-diameter water inlet. The water inlet component includes a water inlet seat and a cap covering the water inlet seat. The cap is connected to the water inlet seat via a connector.

5. The on-board water storage tank of claim 4, wherein: The water inlet seat includes a funnel-shaped seat body, with a sleeve head formed at the tail end of the seat body, a cap interface edge formed near the front end of the seat body, and a mounting flange with mounting holes formed below the cap interface edge. The cap interface edge and the mounting flange are spaced apart, thereby forming an annular positioning groove between the cap interface edge and the mounting flange. The connector includes a connecting ring fitted in the annular positioning groove, and a flexible sheet integrally formed and connected to the connecting ring. The flexible sheet is integrally formed and connected to the cap.

6. The on-board water storage tank of claim 5, wherein: The internal connector includes a hollow, conical plug made of rubber. The large end of the conical plug is connected to the extension tube, and the outer diameter of the large end of the conical plug is larger than the diameter of the extension tube, thus forming a limiting end face at the large end of the conical plug. The small-diameter water inlet is formed with a conical annular inner wall that is larger on the outside and smaller on the inside. The conical plug is inserted into the annular inner wall and fits tightly and seals. The small-diameter water inlet is threaded with a perforated cap. The extension tube passes through the center hole of the perforated cap, which presses against the limiting end face and presses the conical plug into the mating hole formed by the annular inner wall.
