It can be conceived that the washer system for the automotive windshield further includes some other functional modules such as a driving device, an electric control system, etc., which are well-known technologies to those skilled in the art and will not be elaborated herein one by one.

[0022] The washer bottle 10 includes an upper bottle body 11 and a lower bottle body 12 that is snap-fitted with the upper bottle body 11. An inner cavity for accommodating windshield washer fluid is formed by snap-fitting the upper bottle body 11 and the lower bottle body 12. Correspondingly, the connection part where the upper bottle body 11 and the lower bottle body 12 are snap-fitted is waterproofed by using a sealing ring to prevent the windshield washer fluid in the bottle from leaking out from the connection part. Pipe clamps for fixing the water delivery pipe and nameplates for marking the brand and other codes are also provided on the surface of the washer bottle 10, which will not be elaborated in detail herein one by one.

[0023] The washing pump 20 is fixed on the side wall of the washing pot 10. Its water inlet end communicates with the interior of the lower part 12 of the pot body, and its water outlet end is connected to the washing pipeline 40 to provide power for transporting windshield washer fluid. The waterproof rating requirement of the motor of the washing pump 20 is not less than IPX7 to ensure its service life.

[0024] The liquid adding device 30 is used to add windshield washer fluid to the washing pot 10. When the washing pot 10 is placed inside the vehicle, the liquid adding port is arranged near the hood through the liquid adding device 30, which is convenient for adding windshield washer fluid into the pot.

After adding is completed, the pot cover 32 is closed to prevent dust and foreign objects from entering the pot cover 32.

[0027] The liquid adding pipe bracket 33 is arranged on the liquid adding pipe 31 and near the pot cover 32 to fix the liquid adding pipe 31 and the pot cover 32 and prevent the position of the liquid adding port from changing due to vehicle driving and jolting.

[0028] The washing pipeline 40 includes multiple washing hoses 41 and an H-shaped three-way valve body 42 connecting the washing hoses 41.

[0029] The washing hose 41 is a pipeline with a Shore hardness of 65 to 75 degrees, and the operating ambient temperature of the pipeline is -40°C to 120°C to meet the normal use of the system in harsh environments. In this embodiment, the washing hose 41 includes a washing main pipe 411 connected to the washing pump 20, a first washing branch pipe 412 connected to the left nozzle of the front windshield, and a second washing branch pipe 413 connected to the right nozzle of the front windshield. In addition, a washing pipe for spraying water on the rear windshield of the vehicle is also connected to the washing pump 20. It is a connecting water pipe made of corrugated pipe, which should be something that those skilled in the art can think of and is not the main content of the present invention, so it is only briefly described here and not illustrated one by one in the accompanying drawings of the specification.

[0030] The H-shaped three-way valve body 42 is used to connect the washing main pipe 411, the first washing branch pipe 412, and the second washing branch pipe 413, so that the windshield washer fluid flowing out of the washing main pipe 411 flows into the first washing branch pipe 412 and the second washing branch pipe 413 respectively. The H-shaped three-way valve body 42 is a one-way valve, and internally provided with structures such as a rubber gasket, a valve core, a spring, and a valve cover. It is an existing technology itself, which should be well-known to those skilled in the art and is not the main content of the present invention, so it is only briefly described here.

[0031] The washing nozzle 50 is connected to the first washing branch pipe 412 and the second washing branch pipe 413 and is located at the free end of the washing branch pipe away from the H-shaped three-way valve body 42. The washing nozzle 50 includes a front nozzle body 51 connected to the washing hose 41, a nozzle ball 52 provided in the front nozzle body 51, a nozzle chip 53 provided in the nozzle ball 52, a buckle 54 provided on the front nozzle body 51, a valve core 55 provided in the front nozzle body 51, and a spring 56 sleeved on the valve core 55.

[0032] The front nozzle body 51 includes a water inlet end 511 inserted into the washing hose 41, a washing liquid flow channel 512 located inside the front nozzle body 51, and a water outlet 513 connected to the washing liquid flow channel 512. The water inlet end 511 is inserted into the washing hose 41, and the outer wall adopts a frustum-shaped structure with a guiding function so that it is not easy to fall off after being inserted into the washing hose 41. The washing liquid flow channel 512 connects the water inlet end 511 and the water outlet 513, and is a pipeline composed of a straight pipe and a bent pipe for providing a flowing space for the washing liquid. The water outlet direction of the water outlet 413 is perpendicular to the water inlet direction of the water inlet end 511, so that the washing liquid transported from below the front windshield can be sprayed toward the windshield. A cavity is provided in the water outlet 413 for arranging the nozzle ball 52.

[0033] The nozzle ball 52 is a spherical structure arranged at the water outlet 413. When water flows out therefrom, due to the impact force of the water flow ejection, the nozzle ball 52 rotates within the water outlet 413, so that the ejected water flow can rotate within a certain range. In this embodiment, the bead adjustment torque of the nozzle ball 52 is 14.7 N·m - 88.3 N·m, and the adjustable range of the ejection angle is 10° up, down, left, and right respectively.

[0034] The nozzle chip 53 is arranged within the nozzle ball 52 and at the water outlet end of the nozzle ball 52, so that the ejected water mist presents a fan shape. Specifically, the included angle of the water mist is 45° ± 5°. It is an existing technology applied in the field of spray guns and should be understandable to those skilled in the art, so no detailed description will be given here one by one.

[0035] The buckle member 54 is arranged on the front nozzle body 51 and on both sides of the front nozzle body 51. It is two elastic sheets with free ends spaced from the front nozzle body 51, and the extending direction of the elastic sheet is opposite to the insertion direction of the water inlet end 511, for inserting the washing nozzle 50 into the sheet metal part. A groove is arranged at the free end of the buckle member 54 to facilitate buckling on the edge of the sheet metal part. In addition, in order to ensure the tightness when the buckle member 54 is inserted into the sheet metal part, a buckle gasket 57 can also be arranged, which can adapt to different sheet metal thicknesses within a certain range.

[0036] The valve core 55 and the spring 56 are arranged within the washing liquid flow channel 512 and near the water inlet end 511. During the process of ejecting the washing liquid, the pressure of the washing liquid entering from the water inlet end 511 is greater than the elastic force of the spring 56, the spring 56 is compressed, and a gap is opened between the valve core 55 and the water inlet end 511, so that the washing liquid can enter the water outlet 513 along the washing liquid flow channel 512; after the washing is completed and the ejection of the washing liquid stops, the valve core 55 abuts against the water inlet end 511 under the action of the spring 56, thus closing the washing liquid flow channel 512 to prevent air from flowing back. The above structure is an existing technology widely applied in the field of nozzles, so only a brief description is given here.

[0037] Compared with the prior art, the washer system of the automotive windshield provided by the present utility model stores and conveys the washer fluid by setting the washer reservoir 10 and the washer pump 20, with a simple structure and a compact layout, which is convenient to be arranged in the engine assembly of the vehicle. And by setting the refilling device 30, with a bendable pipeline provided, the filling port is arranged on the surface of the vehicle engine assembly, which is convenient for adding the washer fluid into the washer reservoir 10. By setting the washer pipeline 40 to connect the washer nozzle 50, it can adapt to various harsh working environments, and is firmly installed, ensuring the service life of the vehicle washer assembly. Finally, by setting the washer nozzle 50, the nozzle ball 52 is used to provide a rotatable spraying range, and the fan-shaped spraying surface enables a more comprehensive flushing of the windshield, so as to cooperate with the windshield wiper to perform a comprehensive and clean cleaning operation on the windshield.

[0038] The above are only the preferred embodiments of the present utility model, and are not used to limit the protection scope of the present utility model. Any modifications, equivalent replacements or improvements within the spirit of the present utility model are all covered within the scope of the claims of the present utility model.
