A kind of automatically cleaning automobile rearview mirrorTechnical field
The present invention relates to a kind of automobile rearview mirror, be related specifically to and adopt jet and water spray combination removal dust and raindrop back mirror.
Background technology
Along with development and the continuous application of Eltec in automotive system of modern electronic technology, the various performances of automobile are obtained for great raising, by various auto electronic Realization of Product driver and crew to the requirement of automobile various aspects.Back mirror is requisite accessory appliances in driver vehicle processes, but minute surface has dust or often on minute surface, forms a lot of water droplet when driving in the rain, makes chaufeur normally cannot see the situation at rear.Have at present and make evaporation of raindrops by type of heating, also have and on minute surface, coat expelling water plated film cause raindrop cannot stop at minute surface.These methods can play a role, but have some shortcomings, as heating function minute surface costly and can not dust be removed, expelling water plated film is effective when raining heavyly, and still can form a lot of raindrop when light rain.
Summary of the invention
Technical matters to be solved by this invention is: for above-mentioned Problems existing, provides a kind of back mirror being removed raindrop and dust by water spray and air-jet combinatorial.
The present invention is achieved in that
Adopt a mirror apparatus for water spray and air-jet combinatorial, comprise the back mirror of band water injector and air nozzle, water jet standpipe and gas ejector pipe, pressure water tank, pressure gas tank and control unit.
The rain cover that air nozzle and water injector are contained in minute surface front upper place is blocked, facing to minute surface, facing to minute surface water spray and air blowing during work.The angle and direction of air nozzle and water injector can adjust.
Water jet standpipe and gas ejector pipe are two pressure-resistant pipelines, connect back mirror and pressure container respectively.Pipeline there is electromagnetic valve, can be opened and closed by master cock.
Pressure water tank and pressure gas tank are equipped with water and the pressurized air of certain pressure respectively, provide impulsive force for minute surface dewaters.
Control unit comprises control panel and electromagnetic valve, and master cock is arranged on the control panel of operator's compartment, can control the electromagnetic valve on pipeline, also can control the direction of shower nozzle and angle.
Innovative point of the present invention is:
1, adopt jet and water spray combination to carry out mirror surface cleaning, prevent dust accretions and raindrop from being formed;
2, the direction of shower nozzle and angle can dynamic conditioning.
Accompanying drawing explanation
Fig. 1 is device general illustration of the present invention.
Detailed description of the invention
Describe the present invention in detail below in conjunction with accompanying drawing, it illustrates principle of the present invention as the part of this specification sheets by embodiment.
According to Fig. 1, the present invention proposes a kind of self-cleaning rear-view mirror system, comprises the back mirror of band water injector and air nozzle, water jet standpipe and gas ejector pipe, pressure water tank, pressure gas tank and control unit.When minute surface has dust or raindrop impact is driven, chaufeur can utilize the jet of this device and water jet to clean minute surface.Chaufeur can regulate the angle and direction of shower nozzle by the master cock on operation operator's compartment control panel, after aligning, presses clean button and just can remove dust on minute surface and raindrop.
The various change made by those skilled in the art or remodeling all can not depart from the scope of the present invention.
