Description
Technical field
The utility model relates to a kind of automobile lamp, relates in particular to a kind of anti-automobile lamp that hazes.
Background technology
The high temperature that existing automobile front produces when opening and long-time irradiation, the inner long-term temperature difference of headlight is larger, causes air pressure change large, and when headlight was opened, temperature was higher in the lamp body, and air pressure is larger, and hot gas need discharge in the housing; When the car light drop in temperature, the housing internal gas pressure reduces, and needs to absorb ambient atmos to replenish air pressure.In the time of wet weather, the gas humidity that sucks in the car light is higher, easily condenses into steam after entering car light, thereby has affected the illuminating effect of vehicle.For defects, some automobile front arranges a plurality of breather pipes at the bonnet place of headlight and carries out air inlet or exhaust by adopting long breather pipe to prevent condensation vapor, has so not only affected attractive in appearance, and because its complicated structure all makes troubles for installation and use.
Chinese patent notification number CN 201028450Y, February 27 2008 day for announcing, name is called the whole sealed type headlamp, this application case discloses a kind of the whole sealed type headlamp, comprise housing, bulb, interior plug, back shroud and outside dust cover with air-vent, be provided with the semi-transparent rete that nylon material is made between the end face of described interior plug and air-vent.Its weak point is, nylon material have be heated yielding, easy aging characteristic, being applied to be heated for a long time in the headlight very easily affects the service life of headlight, the problem that headlight easily hazes is more serious.
The utility model content
The purpose of this utility model is in order to solve the defective that prior art car headlight easily hazes and a kind of antifog automobile lamp that can prevent that the car headlight from hazing is provided.
To achieve these goals, the utility model is by the following technical solutions:
A kind of anti-automobile lamp that hazes, the housing that comprises sealing, described housing afterbody is provided with drying device, described drying device comprises that inside has the body of cavity, have the passage that links to each other with housing on the body, intrinsic cavity is divided into drying chamber, discharge chamber and inlet chamber, places drier in the drying chamber.In the technical program, exhaust is passed through two different passages with air inlet, by drier the gas that sucks is carried out drying during air inlet, and hot gas plays drying functions to drier during exhaust.Hot gas during exhaust in the light fixture can carry out drying functions to drier, and the high temperature in the light fixture also can play the effect of bake drying agent simultaneously, by the moisture in the drier absorbed air, avoids steam to enter in the light fixture when air-breathing.
As preferably, described discharge chamber and inlet chamber are adjacent, are provided with dividing plate between discharge chamber and the inlet chamber, separate by vent board between drying chamber and inlet chamber and the discharge chamber.In the technical program, keep apart with dividing plate discharge chamber and inlet chamber, with vent board drying chamber and inlet chamber and discharge chamber are separated, avoid drier to enter discharge chamber or inlet chamber.
As preferably, described drying chamber is positioned at the side that body links to each other with housing, and the opposite side of body is discharge chamber and inlet chamber.In the technical program, the side that body links to each other with housing is provided with passage, and the hot gas that automotive headlamp produces because working long hours enters the drying chamber agent that is dried via passage and absorbs.
As preferably, described discharge chamber top is provided with one-way exhaust valve, and the inlet chamber top is provided with breather cheek valve.In the technical program, breather check valve and exhaust check valve are controlled respectively the direction of two air-flows, and a minute different passage carries out air inlet and exhaust, and the long-term repeat function of drier causes the inefficacy of drier when preventing intake and exhaust.
As preferably, one-way exhaust valve and breather cheek valve are diaphragm type one-way valve.In the technical program, diaphragm type one-way valve is fixed on air inlet and the exhaust ports of body.
As preferably, described housing afterbody is provided with the boss that matches for the body passage, and boss is threaded with body.In the technical program, drying device is stand alone type, can directly be installed on the boss of housing, is convenient for changing when the drier activity decreased.
As preferably, the drier of placing in the described drying chamber is silica-gel desiccant.In the technical program, silica-gel desiccant has the advantages that to reuse, and the hot gas of discharging in the light fixture and the temperature of light fixture itself can be dried drier, so that the air to suction carries out demist when air-breathing.
The beneficial effects of the utility model are that the utility model is directly made all-sealed housing, at the housing afterbody passage is set, and at this passage place drying device is set, and utilizes drying device that ambient humidity is controlled, and prevents that lamp interior from hazing.The utlity model has simple in structure, good sealing effect, the anti-effective advantage that hazes.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Among the figure, 1, housing; 2, body; 3, drying chamber; 4, discharge chamber; 5, inlet chamber; 6, dividing plate; 7, vent board; 8, passage; 9, one-way exhaust valve; 10, breather cheek valve.
