Description of drawings
In order to be illustrated more clearly in technical scheme of the present invention, the below will do to introduce simply to the accompanying drawing of required use among the embodiment, apparently, accompanying drawing in the following describes only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the decomposing schematic representation of the light fixture breathing equipment that provides of the embodiment of the invention.
The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described.
As shown in Figure 1, a kind of light fixture breathing equipment 1 that the embodiment of the invention provides is located on the housing 21 of light fixture 2, and this breathing equipment 1 comprises:
Through hole 11, it is opened on the housing 21 and with the inner chamber of housing 21 and is communicated with;
Make when light fixture 2 works long hours that the interior temperature of housing 21 raise, during pressure rises, the air that housing 21 internal pressures are higher will overflow by breathable barrier thing 13 and from the first spiracle 121, the second spiracle 141 and the 3rd spiracle 151, and the air pressure in the housing 21 just gradually equates with housing 21 air pressure outward.When light fixture quits work, housing 21 interior temperature reduce, when the air pressure in the housing 21 is low, the air of housing 21 outsides will be under atmospheric effect, enter in the housing 21 from the first spiracle 121, the second spiracle 141, the 3rd spiracle 151 and breathable barrier thing 13, the air pressure in the housing 21 just gradually equates with housing 21 air pressure outward.Like this, breathing equipment 1 has just reached the purpose of the inner and outer air pressure of balance housing 21, has solved the parts of housing 21 inside of light fixture 2 because of the air pressure problem that explosion damages that raises.Breathing equipment 1 is realized the interior external respiration of light fixture 2 by the first spiracle 121, the second spiracle 141, the 3rd spiracle 151 and breathable barrier thing 13, respiration channel is reasonable in design, has guaranteed that light fixture 2 breathings are smooth and easy, has improved the explosion-proof performance of light fixture 2.
When water enters back cover 15 from the 3rd spiracle 151 on the back cover 15, the part water directly osculum 152 from back cover 15 lateral margins flows out, another part water flows to water fender 14, water is stopped by water-retaining structure 142 on water fender 14, stop water to enter the second spiracle 141, water on the water fender 14 flow to osculum 152 on back cover 15 lateral margins along water-retaining structure 142, and flows out from osculum 152.Like this, breathing equipment 1 has just reached the purpose of waterproof, thereby has improved the water resistance of light fixture 2.
In a preferred embodiment of the invention, described seal closure 12 is specially the rubber seal cover, and rubber seal cover elasticity is high, in the through hole 11 of being convenient to pack into; And rubber seal cover corrosion resistance and good, guaranteed that rubber seal covers under the wet environment to use and do not damage for a long time; The assembling mode of seal closure 12 and through hole 11 preferred interference fit so that seal closure 12 is connected closely with through hole 11, can significantly improve the sealing property between seal closure 12 and the through hole 11.
In a preferred embodiment of the invention, described breathable barrier thing 13 is the inner wrappage that active carbon is housed, and active carbon is wrapped up by asbestos paper, and active carbon has very strong ventilative and adsorption effect, gas can pass through active carbon, but dust can not be passed through by charcoal absorption; Simultaneously asbestos paper has heat insulation, insulation, moisture-proof role, so breathable barrier thing 13 external pressure in balance can also prevent effectively that extraneous steam from entering light fixture 2 inside simultaneously.
In a preferred embodiment of the invention, described water-retaining structure 142 comprises some the second spiracle 141 waterwalls 1421 on every side that are looped around, waterwall 1421 is combined by two or more bar shaped fin or arc fin, offer at least one breach 1422 that supplies water and flow out on the waterwall 1421, waterwall 1422 has at least two-layer, and the breach on each layer waterwall 1,422 1422 staggers mutually.The setting because the breach 1422 on each layer waterwall 1422 staggers mutually, so the water of water-retaining structure 142 outsides can be stopped by waterwall 1421 and can't enter the second spiracle 141; Even the water that enters from the 3rd spiracle 151 of back cover 15 flows into water-retaining structure 142 inside, water also can flow out water-retaining structures 142 from the breach 1422 that waterwall 1422 is offered, and the osculum 152 from back cover 15 lateral margins is discharged at last.Thereby water-retaining structure 142 of the present invention can effectively stop water to enter the second spiracle 141, has significantly improved the water resistance of light fixture 2.
In a preferred embodiment of the invention, described water fender 14, the mode that specifically is fixedly connected with of back cover 15 and housing 21 is: offer at least one the first installing hole 143 on the water fender 14, the first installing hole 143 evenly arranges on water fender 14, offer second installing hole 153 identical with the first installing hole 143 quantity on the back cover 15, and the second installing hole 153 aligns with the first installing hole 143, water fender 14 and back cover 15 are fixedly attached on the housing 21 by some screws 16 that are arranged in the first installing hole 143 and the second installing hole 153, thereby realize water fender 14 and back cover 15 are fixedly attached to purpose on the housing 21.
Consult shown in Figure 1ly, the present invention also provides a kind of light fixture 2 again, and it comprises housing 21, the lamp holder 22 that is connected with housing 21 and foregoing breathing equipment 1.Because light fixture 2 of the present invention is equipped with breathing equipment 1, so the water resistance of light fixture 2 and explosion-proof performance significantly improve, and prolonged the service life of light fixture 2.
The above is preferred embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also are considered as protection scope of the present invention.
