Accompanying drawing explanation
In order to be illustrated more clearly that technical scheme, the accompanying drawing used required in embodiment will be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the decomposing schematic representation of the light fixture breathing equipment that the embodiment of the present invention provides.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
As it is shown in figure 1, a kind of light fixture breathing equipment 1 that the embodiment of the present invention provides, being located on the housing 21 of light fixture 2, this breathing equipment 1 includes:
Through hole 11, its be opened on housing 21 and with the inner space of housing 21;
Seal closure 12, itself and through hole 11 are tightly connected, and seal closure 12 offers at least one first spiracle 121, and the axis of the first spiracle 121 is parallel to the axis of through hole 11, and the first spiracle 121 connects with through hole 11;
Breathable barrier thing 13, it is located in seal closure 12, is used for blocking through hole 11, and breathable barrier thing 13 is only used for passing through gas;
Water fender 14, for pushing down seal closure 12 and fixing with housing 21 being connected, water fender 14 offers at least one second spiracle 141 identical with the first spiracle 121 quantity, second spiracle 141 is alignd with the first spiracle 121, second spiracle 141 is communicated with the first spiracle 121, the axis of the second spiracle 141 is also parallel with the axis of through hole 11, being additionally provided with the water-retaining structure 142 arranged around the second spiracle 141 on water fender 14, water-retaining structure 142 is used for stoping water to enter the second spiracle 141;
Back cover 15, for covering water fender 14 and fixing with housing 21 being connected, the end face of back cover 15 offers at least one 3rd spiracle 151,3rd spiracle 151 and the first spiracle 121 or the second spiracle 141 stagger setting, the axis of the 3rd spiracle 151 is also parallel with the axis of through hole 11, and the lateral margin of back cover 15 offers at least one osculum 152, enters the water in back cover 15 from the 3rd spiracle 151, can discharge from osculum 152, to reach the purpose of waterproof.
Make in housing 21 temperature raise when light fixture 2 works long hours, air pressure is when rising, the air that in housing 21, pressure is higher will pass through breathable barrier thing 13 overflowing from first spiracle the 121, second spiracle 141 and the 3rd spiracle 151, the air pressure in housing 21 just gradually with housing 21 outside air pressure equal. When light fixture quits work, in housing 21, temperature reduces, when air pressure in housing 21 is relatively low, air outside housing 21 will be under atmospheric pressure, enter in housing 21 from first spiracle the 121, second spiracle the 141, the 3rd spiracle 151 and breathable barrier thing 13, the air pressure in housing 21 just gradually with housing 21 outside air pressure equal. So, breathing equipment 1 has just reached the purpose of inner and outer air pressure of balance housing 21, and parts housing 21 within solving light fixture 2 burst because air pressure raises the problem of damage. Breathing equipment 1 realizes the interior external respiration of light fixture 2 by first spiracle the 121, second spiracle the 141, the 3rd spiracle 151 and breathable barrier thing 13, and respiration channel is reasonable in design, it is ensured that light fixture 2 is breathed smooth and easy, improves the explosion-proof performance of light fixture 2.
When water enters back cover 15 from the 3rd spiracle 151 back cover 15, a part of water directly flows out from the osculum 152 back cover 15 lateral margin, another part water Liu Dao water fender 14, water is stopped by water-retaining structure 142 on water fender 14, water is stoped to enter the second spiracle 141, water on water fender 14 flow to the osculum 152 on back cover 15 lateral margin along water-retaining structure 142, and flows out from osculum 152. So, breathing equipment 1 has just reached the purpose of waterproof, thus improve the water resistance of light fixture 2.
In a preferred embodiment of the invention, described seal closure 12 is specially rubber seal cover, and rubber seal cover elasticity is high, it is simple to load in through hole 11; And rubber seal cover corrosion resistance and good, it is ensured that rubber seal cover life-time service in wet condition and do not damage; The assembling mode of seal closure 12 and the preferred interference fit of through hole 11 so that seal closure 12 and through hole 11 are completely embedded, and are remarkably improved the sealing property between seal closure 12 and through hole 11.
In a preferred embodiment of the invention, described breathable barrier thing 13 is the internal wrappage equipped with activated carbon, and activated carbon is wrapped up by asbestos paper, and activated carbon has very strong ventilative and adsorption effect, gas can pass through activated carbon, but dust can be tightly held by activated carbon and can not pass through; Simultaneously asbestos paper has heat insulation, insulation, moisture-proof role, so breathable barrier thing 13 external pressure in balance can also effectively prevent inside extraneous steam entrance light fixture 2 simultaneously.
In a preferred embodiment of the invention, described water-retaining structure 142 includes some waterwalls 1421 being looped around around the second spiracle 141, waterwall 1421 is combined by two or more bar shaped fin or arc fin, waterwall 1421 offers at least one breach 1422 being available for water outflow, waterwall 1422 has at least two-layer, and the breach 1422 on each layer waterwall 1422 staggers mutually. Owing to the breach 1422 on each layer waterwall 1422 staggers setting mutually, therefore the water outside water-retaining structure 142 can be stopped by waterwall 1421 and cannot be introduced into the second spiracle 141; Even if the water entered from the 3rd spiracle 151 of back cover 15 flows into water-retaining structure 142 inside, the breach 1422 that water also can be offered from waterwall 1422 flows out water-retaining structure 142, finally discharges from the osculum 152 back cover 15 lateral margin. Thus, the water-retaining structure 142 of the present invention can effectively stop water to enter the second spiracle 141, significantly improves the water resistance of light fixture 2.
In a preferred embodiment of the invention, described water fender 14, the concrete fixing connected mode of back cover 15 and housing 21 is: offer at least one first installing hole 143 on water fender 14, first installing hole 143 is uniformly arranged on water fender 14, back cover 15 offers second installing hole 153 identical with the first installing hole 143 quantity, and second installing hole 153 align with the first installing hole 143, water fender 14 and back cover 15 are fixedly attached on housing 21 by some screws 16 being arranged in the first installing hole 143 and the second installing hole 153, thus realizing water fender 14 and back cover 15 are fixedly attached to the purpose on housing 21.
Shown in Fig. 1, present invention also offers a kind of light fixture 2, it includes lamp holder 22 and the foregoing breathing equipment 1 that housing 21 is connected with housing 21. Owing to the light fixture 2 of the present invention is equipped with breathing equipment 1, therefore the water resistance of light fixture 2 and explosion-proof performance significantly improve, and extend the service life of light fixture 2.
The above is the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from the principles of the invention; can also making some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
