Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an automotive windshield washer nozzle. Background Technology

[0002] Windshield washer nozzles are an important component of a car's windshield wiper system, primarily responsible for spraying washer fluid to clean the windshield in conjunction with the wipers. Currently, most washer nozzles spray water in a columnar or uneven manner onto the glass, failing to distribute the water evenly and effectively cover the entire windshield area, resulting in incomplete cleaning. Furthermore, during vehicle operation, dust particles can easily enter the washer nozzles, potentially clogging them and preventing proper functioning. This seriously impacts vehicle safety and driving experience. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a car windshield washer nozzle that improves the cleaning effect of the windshield and extends the service life of the nozzle.

[0004] Therefore, the technical solution of this utility model is: a car windshield washer nozzle, including a housing, a water inlet end provided on the rear side of the housing, and a water inlet pipe connected to the water inlet end; multiple nozzles are provided on the front side of the housing, and nozzles are provided inside the nozzles, and the nozzles are connected to the water inlet end through a water supply channel inside the housing; a fan blade structure is provided on the nozzle, and the fan blade structure includes a fan blade and a rotating shaft; the fan blade is rotatably connected to the inner wall of the nozzle through the rotating shaft, and a torsion spring is provided on the rotating shaft, the fan blade can close the nozzle under the action of the torsion spring, and can rotate around the rotating shaft to open under water pressure.

[0005] Based on the above scheme and as a preferred embodiment of the above scheme: the nozzle has a rectangular structure, with a fan blade rotatably installed on each side, and a rubber seal is provided at the edge of the fan blade. When the two fan blades are closed, they abut against each other through the rubber seal.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the front side of the housing is an arc-shaped structure, and the front side of the housing is provided with 3 nozzles, each nozzle is provided with a nozzle, and the orientation interval between adjacent nozzles is 30 to 45 degrees.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the nozzle has a fan-shaped structure with three spray holes at the front end, and the included angle between the spray directions of the three spray holes is 20 to 30 degrees.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: a filter screen is provided at the water inlet end of the shell.

[0009] When water is sprayed, the impact force of the water flow causes the fan blades to rotate around the shaft, opening the nozzle and allowing the water to spray out. When water is not sprayed, the fan blades are closed by the action of the torsion spring, and the nozzle is tightly sealed by the sealing element, thus effectively preventing dust from clogging the nozzle.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The nozzle has built-in fan blades that can open and close automatically. When spraying water, the water flow opens the fan blades, and when spraying stops, the fan blades close and seal automatically to prevent dust from entering. The water inlet is equipped with a high-density filter screen, which provides double protection to prevent sand and impurities from clogging the nozzle.

[0012] 2. Three nozzles are installed on the front of the housing, and the three nozzles are staggered at 30-45 degrees. The fan-shaped water flow of each nozzle covers an area of ​​20-30 degrees, forming a cross-spray net that directly covers most of the windshield, avoiding the blind spots of the traditional columnar water flow cleaning "one line", and cleaning more thoroughly.

[0019] The components in the diagram are labeled as follows: housing 1, nozzle 11, water supply channel 12, water inlet 2, filter screen 21, water inlet pipe 3, nozzle 4, spray hole 41, fan blade structure 5, fan blade 51, rotating shaft 52, and rubber seal 53. Detailed Implementation

[0020] In the description of this utility model, it should be noted that the directional terms such as "center", "horizontal (X)", "longitudinal (Y)", "vertical (Z)", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this utility model.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" or "a number" means two or more, unless otherwise explicitly specified.

[0022] See the attached drawings. The car windshield washer nozzle described in this embodiment includes a housing 1, with a water inlet 2 on the rear side of the housing 1. The water inlet 2 is connected to a water inlet pipe 3. A filter screen 21 is provided at the water inlet 2 of the housing 1. The filter screen 21 is made of stainless steel with fine mesh, which can effectively filter sand, scale and other impurities in the water.

[0023] The front of the housing 1 has an arc-shaped structure with three nozzles 11. Each nozzle 11 contains a nozzle 4, and adjacent nozzles 4 are spaced 45 degrees apart. The nozzles 4 are connected to the water inlet 2 through a water supply channel 12 inside the housing 1. The nozzles 4 have a fan-shaped structure with three spray holes 41 at the front end, and the spray direction of the three spray holes 41 is at an angle of 25 degrees. The fan-shaped nozzles 4, with three spray holes 41 facing different directions inside, can evenly disperse the water flow into a fan-shaped water mist, allowing it to be evenly distributed on the car window.

[0024] The nozzle 11 is equipped with a fan blade structure 5, which includes fan blades 51 and a rotating shaft 52. The nozzle 11 has a rectangular structure, with a fan blade 51 rotatably mounted on each side. The fan blades 51 are rotatably connected to the inner wall of the nozzle 11 via the rotating shaft 52, and a torsion spring is provided on the rotating shaft 52. Under the action of the torsion spring, the fan blades 51 can close the nozzle 11, and under water pressure, they can rotate around the rotating shaft 52 to open. A rubber seal 53 is provided at the edge of the fan blades 51, and when the two fan blades 51 are closed, they abut against each other through the rubber seal 53.

[0025] When water is sprayed, the impact force of the water flow causes the fan blade 51 to rotate around the shaft 52, opening the nozzle 11. The water flows into the nozzle 4 through the internal water supply channel 12 and is evenly distributed on the glass from the spray hole 41. When the water spraying stops, the torsion spring releases its elastic force, causing the fan blade 51 to rotate, so that it tightly fits the nozzle 11 through the rubber seal 53, closing the nozzle 11 to prevent dust and debris from entering and avoid clogging the nozzle 4.

[0026] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected by this utility model. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
