Abstract
The utility model discloses a novel multi-layer ventilating pipeline for an automobile headlamp, which comprises a breathable plastic hose, wherein a plurality of breathable membranes are arranged in the breathable plastic hose, and divide the breathable plastic hose into a plurality of chambers; a drying agent is placed in each chamber; the breathable membranes are packed at the two ports of the breathable plastic hose; and the drying agents are granular. With the adoption of double-hole breathability and multi-layer drying, the novel multi-layer ventilating pipeline is not blocked easily; when the breathable membranes at the outer ends of the novel multi-layer ventilating pipeline are blocked or dropped, the breathable membranes and the drying agents in the novel multi-layer ventilating pipeline can exert effects; and the novel multi-layer ventilating pipeline is good in breathability and drying effect, long in service life, and simple and convenient in integral replacement.
Description
Technical field:
The utility model relates generally to lamp fittings, is exactly more particularly a kind of novel automobile big lamp multilayer ventilating pipe road.
Background technology:
Automobile lamp and outdoor lights are when work, and the lamp intracavity gas can expanded by heating.Descend or break for fear of the lamp body sealing, car light can be reserved passage when design, to guarantee good ventilation and the balance external and internal pressure in lamp chamber.But after steam and dust too much entered the lamp chamber, steam can condense in the interior surfaces of glass of lamp, and dust can be bonded at mirror surface, affects service life and the effect of car light.Common vent hole structure has steam hose, pastes individual layer ventilated membrane, water proof ventilating screw plug etc.Steam hose can cause steam and dust directly to enter in car light, and car light is caused harmful effect.Paste ventilated membrane, can play effective prevention steam and dust and enter the lamp chamber, have permeation functions, easily come off, easily be sticky with and permeation functions is descended greatly by the dust of external contact, mud but paste ventilated membrane.The water proof ventilating screw plug series products can reach the balance inner and outer air pressure, has the waterproof and breathable effect, but impaired or can not be convenient for changing when blocking at ventilated membrane.
The utility model content:
The utility model purpose is exactly in order to make up the defective of prior art, a kind of novel automobile big lamp multilayer ventilating pipe road is provided, its plastic hose of breathing freely is combined utilization with ventilated membrane, so, that inner ventilated membrane is difficult for is impaired, be difficult for blocking because gluing dust mud, bonding firm, longer service life is changed easy car light ventilating pipe fitting.
The utility model is achieved through the following technical solutions:
A kind of novel automobile big lamp multilayer ventilating pipe road, include ventilative plastic hose: be provided with some layers of ventilated membrane in described ventilative plastic hose, the plastic hose of breathing freely is separated into some chambers, each indoor drier that all is placed with, and the two-port of ventilative plastic hose also is encapsulated with ventilated membrane.
Described drier is the particulate dry drying prescription.
When using the utility model, this ventilative plastic hose is placed in the passage of reserving on lamp casing, then uses the bonding plastic pipe fitting of glue and housing connecting portion, make both seal bonding.
Have multi-layered gas-permeable film and drier in the utility model, when outside ventilated membrane damaged, inner can also play a role, and integral body can arbitrarily be changed.
The utility model has the advantages that:
The utility model adopts diplopore ventilative, and multilayer is dry, is difficult for being obstructed; When the outer end ventilated membrane blocks or comes off, still there are inner ventilated membrane and drier to play a role; Ventilative drying effect is good, long service life, and integral replacing is easy.
Description of drawings:
Accompanying drawing is structural representation of the present utility model.
The specific embodiment:
Referring to accompanying drawing 1:
A kind of novel automobile big lamp multilayer ventilating pipe road, include ventilative plastic hose 1: be provided with some layers of ventilated membrane 2 in described ventilative plastic hose 1, the plastic hose 1 of breathing freely is separated into some chambers 3, the interior drier 4 that all is placed with in each chamber 3, the two-port of ventilative plastic hose 1 also is encapsulated with ventilated membrane 2; Described drier 4 is the particulate dry drying prescription.
Claims (2)
1. novel automobile big lamp multilayer ventilating pipe road, include ventilative plastic hose, it is characterized in that: be provided with some layers of ventilated membrane in described ventilative plastic hose, the plastic hose of breathing freely is separated into some chambers, each indoor drier that all is placed with, the two-port of ventilative plastic hose also is encapsulated with ventilated membrane.
2. a kind of novel automobile big lamp according to claim 1 is used the multilayer ventilating pipe road, and it is characterized in that: described drier is the particulate dry drying prescription.
