Abstract
The utility model discloses a car lamp dehumidification and demist device which is used for preventing water mist from generating in a lamp. The car lamp dehumidification and demist device comprises a centrifugal fan and a gas guide pipe, wherein the centrifugal fan is arranged in a rear cover of a lamp shell of a car front lamp, an air inlet of the centrifugal fan faces an inner cavity of the front lamp, the gas guide pipe is located outside the lamp shell of the front lamp, one end of the gas guide pipe is connected with an air outlet of the centrifugal fan, and the other end of the gas guide pipe is connected with an air return port of the lamp shell. The car lamp dehumidification and demist device enables the air inside the front lamp to circulate and flow by means of the centrifugal fan and the gas guide pipe, the temperature difference among all positions inside the lamp is largely reduced, and the water mist is effectively prevented from producing. Due to the fact the centrifugal fan is arranged in the rear cover of the lamp shell, the space inside the lamp is saved. Besides, the car lamp dehumidification and demist device is quite convenient to install and maintain, and well solves the problem that a traditional car lamp dehumidification device is not easy to replace.
Description
Technical field
The utility model relates to a kind of device that prevents from producing in the car headlamp fog, belongs to automobile technical field.
Background technology
At present, car headlamp generally all be with bulb as light source, in headlamp when work,, bulb can produce a large amount of heat, make it near temperature raise, and then cause in the lamp temperature distributing disproportionation even, just very easily produce water smoke if humidity is large in the lamp, affect illuminating effect.The car headlamp of more existing high-end vehicles arranges fan in envelope inner wall, forces to reduce in the mode of air circulation in the lamp temperature difference of different parts in the lamp, removes moisture in the lamp with drier simultaneously, to reach the purpose that prevents that water smoke from producing.The shortcoming of said structure is: fan and drier will take space in the lamp, and are difficult to change, in case fan breaks down or drier lost efficacy just effectively demist.
The utility model content
The purpose of this utility model is the drawback for prior art, and a kind of car light dehumidifying demister that does not take the interior space of lamp and be easy to change is provided.
Problem described in the utility model realizes with following technical proposals:
A kind of car light dehumidifying demister, it comprises centrifugal fan and gas conduit, and described centrifugal fan is installed in the bonnet of car headlamp lamp housing, and its air inlet is towards the headlamp inner chamber; It is outside that described gas conduit is positioned at the headlamp lamp housing, and the one end is connected with the air outlet of centrifugal fan, the return air inlet of another termination lamp housing.
Above-mentioned car light dehumidifying demister, the air inlet place of described centrifugal fan is provided with drier.
Above-mentioned car light dehumidifying demister, the bonnet of described centrifugal fan and lamp housing is connected by screw.
Above-mentioned car light dehumidifying demister, described centrifugal fan and headlamp are connected in parallel.
Above-mentioned car light dehumidifying demister, the return air inlet of described lamp housing and centrifugal fan are positioned at the both sides of bulb.
The utility model utilizes centrifugal fan and gas conduit that the headlamp inner air is circulated, and has greatly dwindled the temperature difference between each position in the lamp, utilizes simultaneously drier to remove moisture in the lamp, has effectively prevented the generation of water smoke in the lamp.Because centrifugal fan and drier are installed in the bonnet of lamp housing, not only saved space in the lamp, and I﹠M is very convenient, has solved well the not easily changeable difficult problem of traditional car light demister.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is scheme of installation of the present utility model;
Fig. 2 is the scheme of installation of fan and drier.
Each list of reference numerals is among the figure: 1, lamp housing, 2, bonnet, 3, gas conduit, 4, bulb, 5, centrifugal fan, 6, drier.
The specific embodiment
Referring to Fig. 1, Fig. 2, the utility model mainly is comprised of gas conduit 3, centrifugal fan 5 and drier 6, centrifugal fan 5 and drier 6 are installed in the inside of headlamp bonnet 2, gas conduit 3 is positioned at lamp housing 1 outside, its two ends connect respectively the air outlet of centrifugal fan 5 and the return air inlet of lamp housing, and the return air inlet of lamp housing and bonnet 2 lay respectively at the both sides of bulb 4.
Centrifugal fan 5 is connected with bonnet 2 by screw, and drier 6 is fixed on the air inlet place of centrifugal fan 5, and bonnet 2 is tightly connected with lamp housing 1, and centrifugal fan 5 is connected in parallel with headlamp.When headlamp is worked, centrifugal fan 5 rotations, air is flowed through successively and is got back in the lamp behind drier 6, centrifugal fan 5, the gas conduit 3 in the lamp, most of heat that air stream sends bulb when bulb is taken away, improved the uniformity of temperature in the lamp, during the agent 6 of air stream drying, its contained humidity is removed, and guarantees can not produce water smoke in the lamp.When centrifugal fan 5 breaks down or drier 6 when losing efficacy, it is namely replaceable to open bonnet 2.
Centrifugal fan can also adopt the screw-in by bonnet that the mode of sheet metal crimping is communicated with the lamp housing inner lead.
