Advantage of the present invention is set forth further below in conjunction with accompanying drawing and specific embodiment.
Consulting Fig. 2 to Fig. 4, is the close-up schematic view of sealing arrangement 130 in the structural representation under headlight washing equipment 100 different operating state of the present invention and an embodiment.In the present invention, headlight for vehicle washing equipment 100 include housing 110, in insert in rushing fluid cylinder 120 and liquid sealing housing 110 and rushing the sealing arrangement 130 in space between fluid cylinder 120 of housing 110, rush in fluid cylinder 120 and pour into cleaning liquid, and pushed to the opening of housing 110 gradually along with the increase of the cleaning liquid amount of pouring into, sealing arrangement 130 then stops in the propelling movement process of rushing fluid cylinder 120 that cleaning liquid enters in the space that rushes and formed between fluid cylinder 120 and housing 110.For the sealing arrangement 130 in the present invention, it comprises one along the outer wall accommodation space 131 that encloses of circumference of housing 110 and the seal ring 132 that is enclosed in accommodation space 131, the a certain position of housing 110 outer wall (can be top or the middle part of housing 110 outer wall) outwards projection, the outer wall of projection part and rush between fluid cylinder 120 and form this accommodation space 131.Under above-mentioned configuration, housing 110 is changed to the structure with a boss by smooth profile.Because accommodation space 131 domestic demand arranges seal ring 132, therefore, projection is all formed accommodation space 131 by the circumferential position of the housing 110 identical with this position level height.Accommodation space 131 as its name suggests, its inside is hollow structure, seal ring 132 is placed on after in this accommodation space 131, rushing the outer wall 121 of fluid cylinder 120 and the sidewall of accommodation space 131, keeping out with " roadblock " form the cleaning liquid entering into and rush between fluid cylinder 120 and housing 110 by fitting respectively.In the present invention, owing to the position of sealing arrangement 130 to be fixed on the somewhere rushed outside fluid cylinder 120, originally rush the space keeping for sealing arrangement 130 to move up and down outside fluid cylinder 120 can save, then housing 110 to inside contract rear basic with rush fluid cylinder 120 and fit, but consider that rushing fluid cylinder 120 needs to slide, rubbing between the two should be not excessive, therefore, housing 110 and rush between fluid cylinder 120 and still leave segment space, then this space content easily flows into cleaning liquid.Sealing arrangement 130 just intercepts cleaning liquid, prevents cleaning liquid from flowing out, and meanwhile, also ensure that the liquid pressure rushing fluid cylinder 120 cleaning liquid inside is enough large, can promote flushing liquor and slide.As the structure of the headlight washing equipment 100 in the present invention, sealing arrangement 130 no longer moves with the movement of rushing fluid cylinder 120, just further, retraction spring for retracting sealing arrangement 130 in prior art also correspondingly eliminates, position shared by former retraction spring, it is with housing 110 and rush the structure that fluid cylinder 120 is connected and save in the lump, with regard to manufacturing process, simplify Fabrication procedure.
Specifically, the headlight washing equipment 100 under initial condition (i.e. non-mode of operation) as shown in Figure 1, cleaning liquid is not also punched in fluid cylinder 120, rushes fluid cylinder 120 and is positioned at initial position.Headlight washing equipment 100 under mode of operation is as shown in Figure 2 after cleaning liquid pours, fluid cylinder 120 will be rushed upwards push, rush fluid cylinder 120 to slide relative to fixing housing 110 and sealing arrangement 130, in sliding process, cleaning liquid is also upwards filled, be positioned at the cleaning liquid rushed between fluid cylinder 120 and housing 110 to be stopped by seal ring 132, then cleaning liquid rushes fluid cylinder 120 inside to flow to only, and finally flow to the nozzle ejection of headlight washing equipment 100.Utilize the relative motion of rushing fluid cylinder 120 and sealing arrangement 130, to change in prior art sealing arrangement 130 relative to the mode of the relative motion of housing 110, thus reduce the size of headlight washing equipment 100.
Continue to consult Fig. 4, in one embodiment of the present invention, in order to ensure the liquid sealing effect of seal ring 132, in the part of fitting with the outer wall 121 rushing fluid cylinder 120, seal ring 132 includes one first contact surface 133 and the second contact surface 134, wherein, first contact surface 133 is near the bottom of housing 110, namely near the bottom of seal ring 132, and the second contact surface 134 is away from the bottom of housing 110, namely near the top of seal ring 132.First contact surface 133 and the second contact surface 134 link closely respectively and rush the outer wall 121 of fluid cylinder 120, then seal ring 132 and rush and between fluid cylinder 120, there are two and seal position, while quantitatively increasing sealing effectiveness, first contact surface 133 can prevent cleaning liquid from flowing out from washing equipment inside, and the second contact surface 134 can prevent outside liquid from flowing into washing equipment inside.To those skilled in the art, the quantity of the contact surface described in the present embodiment is not the restriction to contact surface, also can need to increase or reduce according to the industry of liquid sealing.
Further preferably, a concave station 135 is formed between the first contact surface 133 and the second contact surface 134, particularly, the part being positioned at the seal ring 132 between the first contact surface 133 and the second contact surface 134 concaves, thus the first contact surface 133 and the second contact surface 134 with rush after fluid cylinder 120 fits, seal ring 132 and rush between fluid cylinder 120 and be formed with a space, this space can be used as the shrink value that redundancy increases seal ring 132.During when the width rushing fluid cylinder 120 increases, first contact surface 133 and the second contact surface 134 are due to the existence in concave station 135 space, can outwards (i.e. seal ring 132 outer wall direction) launch, due to this expansion direction and seal ring 132 to be adjacent to direction contrary, then the internal stress of seal ring 132 is also by increasing first contact surface 133 and the second contact surface 134 and the gripping power that rushes between fluid cylinder 120.And when the state of rushing fluid cylinder 120 and never load housing 110 is encased in housing 110, consider the effect of sealing, diameter between seal ring 132 is generally less than the diameter rushing fluid cylinder 120, make both for interference fit clamping, and under having the configuration of concave station 135, that the opening of seal ring 132 can be done is less, the displacement that the first contact surface 133 and the second contact surface 134 launch is larger, just as above, the gripping power that can strengthen the first contact surface 133 and the second contact surface 134 and rush between fluid cylinder 120.
Also be the consideration for above-mentioned purpose, accommodation space 131 has a bottom surface, when seal ring 132 is fixed in accommodation space 131, the bottom of seal ring 132, also namely stop that cleaning liquid flows out one blocks water face 137, support is on this bottom surface, optional or preferably, block water on face 137 at this, offer a groove 138, when as described above rush the situation of moving between fluid cylinder 120 and seal ring 132 time, first contact surface 133 outwards can extend to the part of this groove 138, namely the shrink value of the first contact surface 133 increases further, seal ring 132 and the gripping power rushed between fluid cylinder 120 also strain greatly mutually.Consider seal ring 132 integrally, and rush the various piece of fitting between fluid cylinder 120 and should have identical gripping power.Therefore, in a preferred embodiment, above-mentioned groove 138 is offered along the circumference on surface, the face of blocking water 137, forms a cannelure 138, then the second contact surface 134 evenly outwards launches, and each position gripping power of seal ring 132 is identical.
After the bottom of seal ring 132 and accommodation space 131 blocks water sealing, the top of accommodation space 131, includes an end face, accommodation space 131 and space outerpace is separated, thus seal ring 132 is enclosed in accommodation space 131, also prevent outside water or the inflow of other liquid.In one preferred embodiment, end face is set to a thrust ring 136, the end winding support of its one end and shell, and has a jut 139, the projection direction of this jut 139 is towards seal ring 132, and jut 139 props up seal ring 132 and makes seal ring 132 keep fixed position in accommodation space 131.Be understandable that, in the present embodiment, the configuration of thrust ring 136 outwardly forms the embodiment of accommodation space 131 for the end being positioned at housing 110, outwardly formed for the embodiment of accommodation space 131 for the middle part self of those housings 110, housing 110 itself can be used as the function of thrust ring 136, and thrust ring 136 can be selected as required voluntarily the need of setting.
Owing to needing to rely on the hydraulic pressure of cleaning liquid outwards to spray, rushing the liquid outlet of fluid cylinder 120, be provided with a valve body 140, only when the hydraulic pressure of cleaning liquid reaches some strength, just can back down valve body 140.Consulting Fig. 5 a, 5b, 6a and 6b, is the different views under valve body 140 different conditions, and in the present invention, the side of valve body 140 is set to the structure on lip limit, then correspondingly, the contact portion of the liquid outlet and valve body 140 that rush fluid cylinder 120 is also set to the structure on lip limit.Just because of the design on lip limit, cleaning liquid is in the process backing down valve body 140, and be divided into multiple stage or multi-section type, each lip on lip limit all will as the resistance stoping cleaning liquid ejection.Although for headlight washing equipment 100, need to pour into more cleaning liquid to increase hydraulic pressure, but then, valve body 140 and the sealing force of rushing between fluid cylinder 120 larger, cleaning liquid spray time speed also larger, also better to the cleaning performance of headlight.In the present embodiment, the lip quantity on lip limit is 4, and those skilled in the art can regulate quantity to configure according to actual needs.
More specifically, consult Fig. 7, valve body 140 includes valve shell 141, be arranged on and rush in fluid cylinder 120, valve shell 141 includes a salient 142, by valve shell 141 and the space sealing that rushes between fluid cylinder 120, prevent cleaning liquid from flowing out from this space, avoid cleaning liquid hydraulic loss.Salient 142 annular can be arranged on the rim of valve shell 141, in all directions all with rush fluid cylinder 120 and be close to sealing.
Operationally, cleaning liquid flows in washing equipment the headlight washing equipment 100 of above-described embodiment, due to the sealing effectiveness of sealing arrangement 130, cleaning liquid rushes the space of fluid cylinder 120 by being full of, and constantly pouring along with cleaning liquid, in cleaning liquid, pressure increases all the more, until back down valve body 140.After valve body 140 is backed down, the liquid outlet being located at valve body 140 both sides will expose, and cleaning liquid just flow into nozzle from this liquid outlet, finally spray from headlight washing equipment 100.And after cleaning liquid sprays, because valve body 140 is connected with a spring with rushing bottom fluid cylinder 120, under the effect of elastic force, valve body 140 bounces back playback, again liquid outlet is closed.Below the series of processes of rushing liquid, hydrojet, cleaning is just completed.
Should be noted that, embodiments of the invention have preferably implementation, and not any type of restriction is done to the present invention, any person skilled in art of being familiar with may utilize the technology contents of above-mentioned announcement change or be modified to equivalent effective embodiment, in every case the content of technical solution of the present invention is not departed from, the any amendment done above embodiment according to technical spirit of the present invention or equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
