The utility model adopts the technical scheme that：A kind of automatic cleaning automobile back mirror, including mirror shell and eyeglass, it is describedFresh air inlet has been uniformly arranged on the mirror shell backboard of mirror shell, filter is installed between the mirror shell backboard and eyeglass, in mirror shellLid eaves bottom sets blowing device；
The filter includes air collector and ventilation bag, and the air collector is a flat cavity, and its front portion is provided with and mirrorThe relative filter bores of fresh air inlet on shell backboard, filter bores are provided with the unidirectional deep bead I opened backward, air collector rear wall be provided withThe blowing mouth that ventilation bag communicates, blowing mouth are provided with the unidirectional deep bead II opened backward, and air collector inner chamber is provided with drainage cotton, instituteDrainage cotton patch is stated in air collector inner chamber rear wall；
The blowing device includes gas transmission road and the air nozzle communicated therewith, and the gas transmission road, which is horizontally set in mirror shell, to be coveredEaves bottom simultaneously communicates with ventilation bag, and the air nozzle outgassing direction is to the surface of eyeglass；
The gas collection pot bottom sets discharge outlet.
Its further technical scheme is：The ventilation bag is provided with the appendix connected with car duct.
The air nozzle is taper air nozzle.
Due to using above-mentioned technical proposal, compared with prior art, a kind of automated cleaning automotive rear-view of the utility modelMirror has the advantages that：
1. a kind of automatic cleaning automobile back mirror of the utility model is provided with fresh air inlet, filter and blowing device, whenDuring running car, caused wind in advance can introduce to the mirror shell inner chamber of rearview mirror, and by the dust and moisture filter in airIt is changed into clean gas, automatically, quickly and efficiently can removes the dust on minute surface or dust, or by the raindrop on minute surface, mistWater or snowflake drying, ensure that the visual field of driver is interference-free, had both improved the security of running car, neither influence driving, againSave the energy；
When running car is slow or suspends, side-view mirror glass surface raindrop can effectively be removed by the air-flow of car ductIt is time saving to save trouble with dust；
2. a kind of automatic cleaning automobile back mirror of the utility model is reasonable in design, cost is cheap, economical and practical.
Below in conjunction with the accompanying drawings and embodiment is made to a kind of technical characteristic of automatic cleaning automobile back mirror of the utility modelFurther instruction.

Embodiment
A kind of automatic cleaning automobile back mirror, including mirror shell 1 and eyeglass 5, lay on the mirror shell backboard 11 of the mirror shellFresh air inlet 111 is equipped with, filter is installed between the mirror shell backboard and eyeglass, the bottom of lid eaves 12 sets blowing dress in mirror shellPut；
The filter includes air collector 2 and ventilation bag 4, and the air collector is a flat cavity, its front portion be provided withThe relative filter bores 21 of fresh air inlet 111 on mirror shell backboard 11, filter bores are provided with the unidirectional deep bead I opened backward, air collectorRear wall is provided with the blowing mouth 23 communicated with ventilation bag 4, and blowing mouth is provided with the unidirectional deep bead II opened backward, and air collector inner chamber is setDrainage cotton 22 is equipped with, the drainage cotton patch is in air collector inner chamber rear wall；
The blowing device includes gas transmission road 3 and the air nozzle 31 communicated therewith, and the gas transmission road is horizontally set on mirror shellThe upper bottom of lid eaves 12 simultaneously communicates with ventilation bag 4, and the air nozzle outgassing direction is to the surface of eyeglass 5；
The gas collection pot bottom sets discharge outlet 24.
The ventilation bag is provided with the appendix 6 connected with car duct.
The air nozzle 31 is taper air nozzle.
In above-described embodiment, the fresh air inlet that is set on mirror shell backboard 11 or it is located at middle part or is located at periphery, the number of fresh air inletThe visual actual conditions determination of mesh, generally 6~30.
Operation principle：
When running car, the list in unidirectional deep bead I and the blowing mouth in filter bores is made due to wind speed caused by advanceOpened to deep bead II, air-flow enters air collector, and the drainage cotton dust suction filter set by gas collection top tank structure by fresh air inlet 111Water, the dust and water droplet filtered is excluded by the discharge outlet of gas collection pot bottom, and filtered cleaning gas tream then passes through gas collectionThe blowing mouth 23 of tank rear wall enters ventilation bag, then sprays to eyeglass from taper air nozzle 31 through gas transmission road, by the dust on minute surface orDust is removed, or the raindrop on minute surface, fog or snowflake are dried up；
When running car is slow or suspends, the unidirectional deep bead II in unidirectional deep bead I and blowing mouth in filter boresBecause without wind speed automatic closing simultaneously, then opening car duct switch if desired for cleaning eyeglass, the air-flow of car duct passes through gas transmissionPipe 6 enters ventilation bag, then sprays to eyeglass from taper air nozzle 31 through gas transmission road, and the dust on minute surface or dust are removed, or willRaindrop, fog or snowflake drying on minute surface.
