Notches are formed in two sides of the upper part of the surrounding convex edge. According to the water tank runner manufacturing structure, the surrounding convex edge is arranged at the inner bottom of the water tank lower cover and located on the outer side of the water outlet pipe, so that the surrounding convex edge forms a small closed cavity on the outer side of the water outlet pipe, and a liquid runner in the water tank can be changed, so that the water tank runner can meet water passing resistance and shorten a water flow path under limiting conditions; therefore, compared with the prior art that a closed small cavity is not manufactured by a surrounding convex edge, the water tank can meet the requirements of water passing resistance and inclined suction experiments under the condition that the limit inclination angle is more than 30 degrees and less than 45 degrees.

DETAILED DESCRIPTION

[0019] In order to better understand the purpose, structure and function of the present invention, the flow channel structure of the water tank of the present invention is further described in detail below with reference to the accompanying drawings.

[0020] See also Figure 1-Figure 5The water tank flow channel structure includes a water tank lower cover 1 and a water tank upper cover 2, the water tank upper cover 2 is installed on the upper end of the water tank lower cover 1, the upper outer side of the water tank lower cover 1 is provided with a circle of lower convex edge 12, the lower outer side of the water tank upper cover 2 is provided with a circle of upper convex edge 22, the upper convex edge 22 is tightly attached to the top of the lower convex edge 12, the upper end of the lower convex edge 12 is provided with a circle of annular groove 13, the lower end of the upper convex edge 22 is fixed with a circle of annular boss 23, the annular boss 23 is plugged into the annular groove 13 and interference fit. When the water tank upper cover 2 is installed on the upper end of the water tank lower cover 1, it is necessary to make the upper convex edge 22 of the water tank upper cover 2 close to the lower convex edge 12 of the water tank lower cover 1, and at the same time make the annular boss 23 of the upper convex edge 22 inserted into the annular groove 13 of the lower convex edge 12 and interference fit, so as to perform splicing and installation of the water tank lower cover 1 and the water tank upper cover 2;

[0021] A clamping assembly 3 is installed between the upper flange 22 and the lower flange 12. The clamping assembly 3 includes an upper pressing plate 31 and a lower pressing plate 32. The upper pressing plate 31 is elastically connected to the upper part of the lower pressing plate 32. The upper part of the upper pressing plate 31 presses the upper end of the upper flange 22, and the lower part of the lower pressing plate 32 presses the lower end of the lower flange 12. A sliding groove 36 is provided inside the lower pressing plate 32. A slider 35 is slidably connected inside the sliding groove 36. A sliding rod 34 is fixed to the upper end of the slider 35. The upper part of the sliding rod 34 moves through the lower pressing plate 32. The upper part of the sliding rod 34 is fixed to the lower part of the upper pressing plate 31. The upper end of the slider 35 is connected to the inner part of the sliding groove 36. The spring 37 is connected between the top and the outside of the slide bar 34. After the water tank lower cover 1 and the water tank upper cover 2 are spliced and installed, if it is necessary to reinforce the water tank lower cover 1 and the water tank upper cover 2, the upper pressure plate 31 is pressed against the upper end of the upper flange 22, and the lower pressure plate 32 is pressed against the lower end of the lower flange 12. The spring 37 gives a downward elastic force to a slider 35, and the slider 35 gives a downward force to the slide bar 34. In this way, the slide bar 34 will give a downward force to the upper pressure plate 31, so that the upper pressure plate 31 and the lower pressure plate 32 can cooperate to press the upper flange 22 and the lower flange 12, ensuring the stability of the water tank lower cover 1 and the water tank upper cover 2 after installation;

[0022] A limiting post 24 is fixed to the upper end of the upper convex edge 22, and a limiting hole 33 is formed on the upper portion of the upper pressing plate 31. The limiting post 24 is plugged into the limiting hole 33. When the upper pressing plate 31 is pressed against the upper convex edge 22, the limiting post 24 can be aligned with the limiting hole 33 and inserted to achieve the positioning effect.

[0023] The surface of the water tank upper cover 2 is connected with a water inlet pipe 21, and the lower side of the surface of the water tank lower cover 1 is fixed with a water outlet pipe 11, and the bottom of the water tank lower cover 1 is fixed with a surrounding convex edge 14, which is located on the outside of the water outlet pipe 11. Notches 15 are provided on both sides of the upper part of the surrounding convex edge 14. By providing a circle of surrounding convex edges 14 on the bottom of the water tank lower cover 1 and on the outside of the water outlet pipe 11, the surrounding convex edge 14 is used to create a closed small chamber on the outside of the water outlet pipe 11, which can change the liquid flow path in the water tank so that it can meet the water resistance under extreme conditions and shorten the water flow path. Figure 7 As shown, the water flows into the inner side of the convex edge 14 and then into the outlet pipe 11. Compared with the current closed small chamber without the convex edge 14, the water tank can meet the water resistance and inclined suction tests under the extreme inclination angle of 30° < road surface inclination angle < 45°.
