The embodiments of the present application improve the shape of the sprayed liquid, the fan angle and the spray angle of the nozzle by improving the structure of the nozzle, and fully cover the vehicle glass, so that the vehicle glass cleaning is more thorough. Specifically, the fluid can be a liquid, specifically can be glass water.

[0061] In the embodiment of the present application, the second area channel includes a fluid inflow end and a fluid outflow end, wherein the pore diameter of the fluid inflow end is larger than the pore diameter of the fluid outflow end. Specifically, the second area channel is semispherical, which is more conducive to improving the fluid spraying effect of the nozzle.

Specifically, the range of the acute angle is 10° to 50°. The spraying angle of the fluid sprayed by the nozzle opening is 70 degrees to 140 degrees. The spraying angle here is the fan-shaped spraying angle shown in FIG. 2.

[0063] In the embodiment of the present application, the end of the nozzle 5 close to the main body 1 is the spray-in end, and the end away from the main body 1 is the spray-out end. A reference surface M1 is arranged perpendicular to the end surface of the spray-out end, the end surface of the spray-out end is divided into two symmetrical parts (i.e., the first part and the second part), and a division line is formed at the spray-in end. The first tangent surface M2 (i.e., the second face) is formed by rotating one of the two parts by a certain angle along the reference surface M1 with the division line as the rotation center line. The second tangent surface M3 (i.e., the fourth face) is formed by rotating the other part by a certain angle along the reference surface M1 with the division line as the rotation center line. The nozzle 5 is cut along the first tangent surface M2 and the second tangent surface M3 to form the nozzle opening 6. The fluid enters the main body 1 through the input end of the jet channel, is transmitted to the spray-in end of the nozzle 5 after being pressurized by the output end, and is finally sprayed out in parallel fan shape by the nozzle opening 6 of the spray-out end. The second area channel Q5 is a semispherical area channel. The nozzle 5 in this embodiment is spherical, but can also be square or other shapes, which is determined according to the installation position and space.

[0064] The nozzle opening 6 of the spray head provided by the embodiment of the present application is improved in design. The nozzle opening 6 is formed by cutting the nozzle 5 along the first tangent surface M2 and the second tangent surface M3. The main body part is designed to have an input end larger than an output end. The fluid enters the nozzle 5 through the input end and the output end of the jet channel after being pressurized, and is finally sprayed out in parallel fan shape by the nozzle opening 6 of the spray-out end. The shape of the sprayed liquid, the fan angle, and the spraying angle of the spray head are improved, and the vehicle glass is fully covered, so that the vehicle glass is cleaned more thoroughly.

[0065] Referring to FIG. 2, the fan spraying angle of the nozzle opening 6 is 70° to 140°. The fan spraying angle can also be selected to be less than 70 degrees or more than 140 degrees. The fan spraying angle of the nozzle opening is specifically the angle of the fluid sprayed out of the nozzle opening with reference to the reference surface.
