The utility model relates to an automobile basic hand tool, in particular to an automobile windscreen washing device which can effectively preventing a nozzle from leaking water. The washing device comprises a washing kettle with a washing pump, and further comprises the washing nozzle. The washing pump is communicated with the washing nozzle through a washing soft pipe, and a one-way valve is arranged inside a water spraying channel of the washing nozzle. The washing device has the advantages that the one-way valve is integrated inside the washing nozzle, when a washing switch is turned off, the washing pump stops working, the pressure of washing liquid reduces quickly, and when the pressure of the washing liquid is smaller than the pressure for opening the nozzle, the nozzle can be closed immediately, so that the problem that the washing liquid flows out is effectively solved.
Description
Technical field
The utility model relates to a kind of automobile basic hand tool, especially relates to a kind of automobile window glass wash mill that can prevent effectively that nozzle from leaking.
Background technology
Automobile window glass is easily dirty, and at present a lot of automobiles all have been equipped with this driver's tool of front windshield glass wash mill, can in time clean front windshield glass with this wash mill when needing, and guarantees that the chaufeur forward visibility is clear.Existing automobile washing device has generally comprised the parts such as Windshield Washer, washer pump, nozzle and check valve, and check valve is contained on the washer pump of Windshield Washer, then is connected with nozzle by the washing flexible pipe.As publication number be: a kind of automotive glass washer arrangement that the Chinese utility model of CN101032951A provides; Comprise washer pump; Described washer pump has the outlet that is communicated with at least one automobile glass scrubber nozzle phase fluid; This device comprises tprque convertor; Described tprque convertor has wherein the bearer element with the chamber; Be furnished with interchangeable filter in described chamber; Described liquid unitor also has the insertion element that is connected to described bearer element; Wherein said bearer element is communicated with described washer pump phase fluid; Described insertion element is communicated with described at least one nozzle phase fluid.The check valve of this patent is connected on washer pump, after washer pump starts, and washer pump work, cleansing fluid enters from Windshield Washer in washer pump, after the pressure of cleansing fluid surpasses the response pressure of check valve, and the check valve conducting, cleansing fluid arrives nozzle in washing flexible pipe flow at high speed, and sprays from nozzle.After the washer pump switch cuts out, washer pump quits work, and owing to still existing cleansing fluid in the washing flexible pipe, the negative pressure that the washing hose inner wall produces is not enough so that swiftly flowing cleansing fluid stops flowing immediately, a small amount of cleansing fluid still can flow out from nozzle, makes engine compartment cover produce spot.
The utility model content
The utility model is mainly after closing for the existing device of existing wash mill, and the problem that cleansing fluid still can flow out from nozzle after providing a kind of safe and reliable, device to close, can effectively prevent the automobile window glass wash mill of cleansing fluid outflow.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of automobile window glass wash mill, comprise the Windshield Washer with washer pump, it also comprises Washing spray nozzle, washer pump is communicated with Washing spray nozzle by the washing flexible pipe, is provided with check valve in the water spray passage of Washing spray nozzle.The utility model is integrated into washer nozzle inside with check valve, makes washer nozzle self have non-return valve function, and washer pump directly is connected with nozzle with non-return valve function by the washing flexible pipe.When the wash switch closure, cleansing fluid is pumped in washer pump work, and reach the response pressure of nozzle when cleansing fluid pressure after, cleansing fluid sprays from nozzle.Close when wash switch, washer pump quits work, the pressure drop of cleansing fluid, and after the response pressure of pressure less than nozzle of cleansing fluid, nozzle can turn-off immediately, can effectively solve the problem that flow of liquor goes out.
As preferably, described washing flexible pipe is flexible hose.Spiral tube is telescopic flexible pipe, nozzle cleaning front windshield glass easy to use.Flexible hose elasticity is better.
As preferably, described washing flexible pipe is bonding by bonded adhesives and Washing spray nozzle, and junction both is connected with clip.The washing flexible pipe uses bonded adhesives and clip and Washing spray nozzle to couple together, and connects comparatively solid and reliablely, can prevent effectively that junction both from leaking.
As preferably, described Windshield Washer is provided with liquid inlet and liquid outlet, and washer pump is located at the liquid outlet place of Windshield Washer.Cleansing fluid is supplemented in Windshield Washer from liquid inlet, and flows in washer pump from liquid outlet.
As preferably, be connected with master cock on described washer pump.Master cock is the unlatching of washer pump and closed switch.
Therefore, the beneficial effects of the utility model are: check valve is integrated into Washing spray nozzle inside, after wash switch is closed, washer pump quits work, the pressure drop of cleansing fluid, after the response pressure of pressure less than nozzle of cleansing fluid, nozzle can turn-off immediately, can effectively solve the problem that flow of liquor goes out.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Shown in figure: 1-Windshield Washer, 2-washer pump, 3-Washing spray nozzle, 4-wash flexible pipe.
