Description
Technical field
The present invention relates to a kind of washer for automobile head light.
Background technology
Automobile in the process of moving, its head lamp can be stained with dirt and influence its illuminating effect.Washer for automobile head light is when car headlamp need clean, and cleans to the preceding photoscope spraywashing liquid of head lamp, with the illuminating effect that guarantees car headlamp, the safety that guarantees vehicle drive.
Attractive in appearance for the air dynamic behaviour that do not destroy automobile and automobile appearance, washer for automobile head light have that the state of stretching out promptly cleans state and contraction state is is promptly received and kept state.The washer for automobile head light tool extend out to the car light cleaning positions in auto body under the cleaning state, car headlamp spraywashing liquid is cleaned.The washer for automobile head light tool shrinks and is hidden in the car body under the harvesting state, keeps the complete sum of auto body attractive in appearance.
Summary of the invention
Technical matters to be solved by this invention is: a kind of washer for automobile head light that is different from prior art is provided, is guaranteeing under the prerequisite of cleaning performance, make that structure is simpler, manufacturing cost is lower.
The technical scheme that the present invention solves its technical matters employing is: mainly be made up of nozzle assembly, piston, spring, pedestal, water inlet, cylinder body; Pedestal is provided with an annular recess, the outer wall of annular recess and cylinder body constitutes flow-guiding channel jointly, cylinder body has water conservancy diversion inlet and diversion outlet, and piston has the pod apertures that is communicated with its inner chamber, and the afterbody in piston stretches into cylinder body is equipped with v-ring, following v-ring and end cap; Nozzle assembly is made up of shower nozzle, deflection cone and nozzle, and communicates with piston cavity; Constitute the cleaning liquid passage jointly by above-mentioned feature.
The principle of work of washer for automobile head light of the present invention: when pump working, have pressure wash liquid and enter piston cavity, the pressure of cleaning liquid is greater than spring force at this moment, and piston moves ahead.When piston motion during to the position of as shown in Figure 1 the state that stretches out, flow-guiding channel conducting, cleaning liquid sprays through nozzle assembly, cleans car headlamp.When water pump quit work, cleaning liquid lost pressure, and piston reverts to harvesting state (see figure 2) under the elastic force effect of spring.
The present invention compared with prior art has following major advantage:
One, different with existing design, be mainly reflected in: structure is simpler, and number of parts is few, stable, the good rigidity of jet stem supporting, integrated artistic is good or the like.
They are two years old, simple in structure being embodied in: compare with existing certain existing design, do not have parts such as the interior pull bar of cavity of resorption, spring, auxiliary piston,, solved the conduction problem of pressure fluid when cleaning positions is arrived in piston motion with water conservancy diversion inlet, diversion outlet and the flow-guiding channel design of uniqueness.The advantage that has kept the mechanical type Open valve can avoid pressure to reduce like this, has increased spouting velocity.Compare with the existing design of another kind, do not have the check valve in the epicoele, promptly reduced parts such as valve gap, spool, little spring, sealing shroud, like this, the differential pressure that can avoid check valve to produce has in the course of the work increased spouting velocity.
Its three owing to increased spouting velocity, help improving the cleaning performance of car headlamp.
Its four because simple in structure, saved some parts, therefore can reduce manufacturing cost, use more reliable.
Its five owing to have an above-mentioned advantage, therefore not only can substitute the Headlamp cleaner product of existing high-grade automotive use, and be beneficial in, low-grade automobile applies, market outlook are good.

The specific embodiment
The present invention is a kind of washer for automobile head light, its structure such as Fig. 1 are to shown in Figure 7, mainly form by nozzle assembly 1, piston 2, spring 3, pedestal 7, water inlet 8, cylinder body 9, wherein: pedestal 7 is provided with an annular recess, the outer wall of this groove and cylinder body 9 constitutes flow-guiding channel 16 jointly, and cylinder body 9 has water conservancy diversion inlet 15 and diversion outlet 17; Piston 2 has the pod apertures 19 that is communicated with its inner chamber 18, and the afterbody that stretches in the cylinder body at piston 2 is equipped with v-ring 4, following v-ring 5 and end cap 6; The fastening head that is contained in piston of nozzle assembly can move with piston, and it is made up of shower nozzle 11, deflection cone 12 and nozzle 13, and communicates with piston 2 inner chambers; Constitute the cleaning liquid passage jointly by above-mentioned feature.
Described v-ring 4 and the following v-ring 5 gone up, its effect is: when piston is in control position, the seal cavity that forms by last v-ring and following v-ring, make the liquid in the cylinder body enter flow-guiding channel 16, enter piston cavity by diversion outlet 17, pod apertures 19 again by water conservancy diversion inlet 15.Described seal ring can be replaced by the seal ring of y-shaped ring, O-ring seals or other shape.Seal ring can also be other any type of element that seals.
Described nozzle assembly 1, its function are spraywashing liquid, realize the cleaning to car headlamp.
Described cylinder body 9, its inner chamber 14 is the passage of piston, also is the cleaning liquid passage simultaneously; Its water conservancy diversion inlet 15 and diversion outlet 17 can respectively have 1～8, or decide according to actual conditions, and they can be distribution symmetrically in a circumferential direction, perhaps are non-homogeneous, distribution or asymmetrical distribution.
Described piston 2, its function are the state that stretches out and the contraction states of realizing cleaning device; Its head support nozzle makes it reach the cleaning positions of car headlamp when stretching out state; Its afterbody plays sealing and guiding current, realizes stretching out and shrinking of cleaning device under the effect of pressure flow and spring.This piston can have 1～6 pod apertures 19, is evenly distributed in a circumferential direction, perhaps is non-uniform Distribution.
Described spring 3: when this cleaning device was not worked, spring 3 can make piston element shrink and be hidden in the car body, keeps the harvesting state of cleaning device.Spring 3 is contained between pedestal 7 and the piston 2.
Described pedestal 7, water inlet 8 tightly are enclosed within the outside of cylinder body.On water inlet 8 tail ends O-ring seals 10 is housed, when itself and cleaning liquid rubber tube join, plays the sealing cleaning liquid.
Described flow-guiding channel 16 is a ring-type, perhaps can be substituted by the passage of conducting water conservancy diversion inlet, diversion outlet, and the cross sectional shape of this passage comprises quadratic curves such as circle, semicircle, ellipse, half elliptic, involute shape, and shape such as polygon.Polygon is triangle, trapezoidal, rectangle, pentagon etc.
Sketch working process of the present invention below in conjunction with accompanying drawing:
When not working, piston 2 makes this cleaning device remain on contraction state shown in Figure 2 under the application force of spring 3.
This cleaning device working process: under the pressure effect of the cleaning liquid that water pump provides, piston 2 stretches out in cylinder body 9, (see figure 1) during to eject position, under the sealing function of last v- ring 4 and 5 formation of following v-ring, liquid in the cylinder body 9 enters flow-guiding channel 16 by water conservancy diversion inlet 15, enter piston cavity 18 by diversion outlet 17, pod apertures 19 again, through nozzle 13 ejections, car headlamp is carried out spraywashing again.
When finishing the cleaning of car headlamp, water pump stops to provide cleaning liquid in cylinder body 9, because the pressure in the cylinder body 9 reduce, resets at the elastic force effect lower piston 2 of spring 3, has promptly got back to punctured position shown in Figure 2.This moment, cleaning device was hidden in interior of body fully, kept the attractive in appearance of the air dynamic behaviour of vehicle body and automobile appearance.
