[0051] The present invention discloses a spray head for a vehicle windshield wiper. Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7 and Figure 8The invention comprises a main body 1 and a nozzle 5. The main body 1 has a plurality of regional channels for fluid to pass through. The diameters of the plurality of regional channels gradually decrease along the flow direction L of the fluid. The plurality of regional channels are connected to form a jet channel. The jet channel has an input end for fluid to pass through and an output end for the fluid. The diameter of the output end is smaller than the diameter of the input end. The nozzle 5 has a hemispherical regional channel inside. The end of the nozzle 5 close to the main body 1 is the injection end, and the end away from the main body 1 is the ejection end. A reference plane M1 is set along the end face perpendicular to the ejection end, and the end face of the ejection end is divided into two mutually symmetrical parts. A dividing line is formed at the injection end. The reference plane M1 is used to divide the ejection end. The first section M2 is formed after rotating toward one of the split bodies at a certain angle along the reference plane M1 with the dividing line as the rotation center line, and the second section M3 is formed after rotating toward the other split body at a certain angle along the reference plane M1 with the dividing line as the rotation center line. The nozzle 5 is cut along the first section M2 and the second section M3 to form a nozzle opening 6; wherein, the fluid enters the main body 1 through the input end of the jet channel, and is then pressurized by the output end and transmitted to the injection end of the nozzle 5, and finally is ejected from the nozzle opening 6 at the ejection end in a parallel fan shape, and the hemispherical regional channel is the fifth regional channel Q5; the nozzle 5 is spherical in this embodiment, and can also be square or other shapes, depending on the installation location and space.
[0052] The nozzle for a vehicle windshield wiper provided in an embodiment of the present invention has an improved design for the nozzle opening 6. The nozzle opening 6 is formed by cutting the nozzle 5 by the first section M2 and the second section M3. The input end of the main part is designed to be larger than the output end. The fluid is pressurized through the input and output ends of the jet channel and then transmitted to the injection end of the nozzle 5. Finally, it is ejected from the nozzle opening 6 at the ejection end in a parallel fan shape. The shape of the sprayed liquid, the fan angle and the injection angle of the nozzle are improved, and the vehicle glass is fully covered, so that the vehicle glass is cleaned more thoroughly.
[0053] Please continue to see Figure 2 The fan-shaped spray angle of the nozzle opening 6 is 70° to 140°. The fan-shaped spray angle of the nozzle opening 6 is preferably 70° to 140°. The fan-shaped spray angle of the nozzle opening 6 is less than 70° and more than 140°.

The outer water inlet hole is preferably coarse in diameter and the inner water inlet hole is fine in diameter, D1>D2, to increase the water pressure. In one specific embodiment, D1=1.5mm, D2=0.8mm. The water inlet hole is preferably coarse in diameter. D1=D2.
[0055] See also Figure 4 The angle portion between the first section M2 and the second section M3 is a cutting portion, and the cutting portion is separated from the nozzle 5. The hemispherical regional channel is cut to form a nozzle opening 6.
[0056] It should be noted that the angle between the first section M2 and the second section M3 can be formed by a cutting process or by other manufacturing processes (such as one-step forming, etc.), and this application does not make any specific limitation.

[0059] Please continue to see Figure 3 , the diameter of the first area channel Q1 is greater than the diameter of the third area channel Q3, increasing the flow rate.
[0060] Please continue to see Figure 3 The second area channel Q2 has two openings, one of which has a diameter larger than the other opening opposite thereto, thereby increasing the flow rate of the fluid.
[0061] It should be noted that the first zone channel Q1 may be directly connected to the third zone channel Q3 (ie, the second zone channel Q2 may not be provided).
[0062] Please continue to see Figure 2 , further comprising a connecting portion 4, which is disposed between the nozzle 5 and the main body 1, extending the length of the third region channel Q3 and increasing the flow rate. The connecting portion 4 is cylindrical in this embodiment, and may also be square or other shapes as required.
[0063] Please continue to see Figure 2 , and also includes a positioning portion 3, which is covered on the outer wall of the main body 1 and can be any shape suitable for installation, such as cylindrical, square, or straight slot, to facilitate the installation of the nozzle. The outer wall of the positioning portion 3 has at least one surface that is flat, convex, or concave, to perform angular positioning of the nozzle to prevent deviation.
[0064] Please continue to see Figure 2 , and also includes a mounting portion 2, which is arranged at the end of the main body 1 away from the nozzle 5. Located at the bottom layer of the nozzle, it is cylindrical with protruding edges and corners, and can also be square or other shapes according to installation needs, or without protruding edges and corners.
[0065] The spraying mode of the nozzle when used on the wiper is continuous spraying, intermittent spraying or alternating spraying. Continuous spraying is preferred, and intermittent spraying or alternating spraying is secondarily preferred. Among them, alternating spraying means that the left and right wiper blades spray alternately.

[0067] The spray head sprays the rear lower glass at an angle of 10° to 90° on the wiper. Preferably, the spray head sprays the rear lower glass at an angle of 10° to 50°. Secondary spraying sprays the rear lower glass at an angle of 5° to 90°.
[0068] The direction of the liquid sprayed by the nozzle is to spray backward and downward on the wiper, or to spray forward and downward, or vertically downward, or to the side, or to spray laterally and downward, or to spray laterally and vertically. The direction of the liquid spraying means that the liquid can be sprayed in different directions on the wiper blade. Preferably, the liquid is sprayed backward (rear and downward), and secondarily, it is sprayed forward, forward and downward, vertically downward, to the side, to spray laterally and downward, or to spray laterally and vertically.
[0069] The distance between the nozzle and the glass surface is 10 mm to 80 mm.

This time, the tee and the nozzle can be effectively sealed after installation.
[0074] The height dimensions of each layer of the nozzle can be changed according to different requirements, and the shape of each layer of the nozzle can be any other shape according to installation needs. The water inlet hole inside the nozzle can be circular or in other shapes.
