Abstract
The utility model relates to a backflow-prevention washer nozzle which comprises a nozzle body and a nozzle copper ball, wherein a cavity is formed in the nozzle body, a water-proof valve is arranged inside the cavity, and springs are arranged on two sides of the water-proof valve. When a switch of a washer is switched on, a washing motor operates to produce power, washing liquid enters the washer nozzle through a flexible washing pipe and enters into the washer through a water outlet channel, pressure of water drives the springs to move towards the two sides, the valve is opened, and the washing liquid is ejected to glass through the nozzle copper ball. When the switch of the washer is switched off, the motor stops operating, pressure of the washing liquid is lowered, the springs instantly close the valve by means of elastic performance of the springs, and backflow of the washing liquid is effectively prevented.
Description
Technical field
The utility model belongs to automobile technical field, relates to a kind of wiper nozzle, relates in particular to a kind of anti-return washer nozzle.
Background technology
Along with the day by day raising of living standard, people are also more and more higher to the dependence of car.Some car washer has sprayed the phenomenon that exists cleaning solution to reflux behind the cleaning solution at present, cleaning solution refluxes and has stayed in the washer flexible pipe of long distance conveying, also have entering of air thereupon, both affected the clean result that cleaning solution uses next time, can make again when washer is opened next time, cleaning solution does not have very first time ejection, causes the dried brush of wiper, affect the life-span of wiper, thereby cause car owner's complaint.
Chinese patent notification number CN201321019Y, on October 7 2009 day for announcing, name is called nozzle and has the washer of described nozzle, and described nozzle comprises: nozzle body, described nozzle body have first end and the second end; Spray tongue accommodation section, described spray tongue accommodation section is arranged on the first end of described nozzle body; The spray tongue, described spray tongue is contained in the described spray tongue accommodation section; Pipe connector lug, described pipe connector lug are arranged on the second end of described nozzle body; And the nozzle fixed part, described nozzle fixed part is fixed to described nozzle body the inner panel of the bonnet of vehicle.Its weak point is that there is the phenomenon that cleaning solution refluxes in the nozzle of washer on the wiper, causes the dried brush of windscreen wiper, affects the life-span of windscreen wiper.
The utility model content
The purpose of this utility model is the phenomenon that exists cleaning solution to reflux for the nozzle that solves washer on the existing wiper, causes the dried brush of windscreen wiper, affect windscreen wiper life-span defective and a kind of anti-return washer nozzle is provided.
To achieve these goals, the utility model is by the following technical solutions:
A kind of anti-return washer nozzle comprises nozzle and nozzle copper ball, is provided with cavity in the described nozzle, and waterproofing valve is installed in the cavity, and described waterproofing valve both sides are provided with spring.In the technical program, when opening washer switch, the washing motor running produces power, make cleaning solution enter washer nozzle by the washing flexible pipe, enter inside by exhalant canal, the pressure of water forces spring toward two lateral movements, valve open, cleaning solution be by the copper ball of nozzle, directive glass; When disconnecting the switch of washer, motor shuts down, and the pressure of cleaning solution reduces, and spring has prevented the backflow of cleaning solution effectively because the elastic performance of self is closed valve immediately.
As preferably, described waterproofing valve is check valve.
As preferably, waterproofing valve is arranged between exhalant canal and the nozzle copper ball.
The beneficial effects of the utility model are, when disconnecting the switch of washer, motor shuts down, the pressure of cleaning solution reduces, spring has prevented the backflow of cleaning solution effectively because the elastic performance of self is closed valve immediately, can not have very first time ejection because of cleaning solution when having guaranteed wiper use next time, and cause the dried brush of wiper, affect the life-span of wiper.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Among the figure, 1, waterproofing valve; 2, spring; 3, nozzle copper ball; 4, cavity.
The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing, the utility model is further explained:
With reference to Fig. 1, a kind of anti-return washer nozzle comprises nozzle and nozzle copper ball 3, is provided with cavity 4 in the described nozzle, cavity 4 interior installation waterproofing valves 1, and described waterproofing valve 1 both sides are provided with spring 2.Described waterproofing valve 1 is check valve.Waterproofing valve 1 is arranged between exhalant canal and the nozzle copper ball 3.
When opening washer switch, the washing motor running produces power, make cleaning solution enter washer nozzle by the washing flexible pipe, enter inside by exhalant canal, the pressure of water forces spring toward two lateral movements, valve open, cleaning solution be by the copper ball of nozzle, directive glass; When disconnecting the switch of washer, motor shuts down, and the pressure of cleaning solution reduces, and spring has prevented the backflow of cleaning solution effectively because the elastic performance of self is closed valve immediately.
