  • Electrothermal type that is, electric heating parts are arranged behind the lens. This is the only technology currently used, but it can only be defrosted. The effect of water drops is not good, and the frost and water drops on the window glass cannot be removed.
  • Spray type that is, the liquid is sprayed to the rearview mirror to remove water drops.
  • the Chinese utility model patent with the announcement number CN2413953Y the water sprinkler affects the appearance of the rearview mirror, and cannot remove the window glass water droplets.
  • Another utility model patent with the announcement number is CN201021262Y.
  • the nozzle is directly mounted on the door, which seriously affects the appearance.
  • a common drawback of these methods is that the design of the nozzle is neglected, affecting the appearance of the vehicle or the mirror, and there is no improvement in the liquid to be sprayed.
  • the use of ordinary water or existing cleaning fluid to remove water droplets is not ideal.
  • the object of the present invention is to provide a perfect and simple car rearview mirror and window glass bead elimination solution for the prior art, which can quickly remove water drops on the rear view mirror and the window glass.
  • the present invention is for removing mist, frost, snow, The effects such as contamination are also very good.
  • the reason why the surface of the object forms water droplets is because of the difference in hydrophilicity in different areas of the surface of the object, that is, some places are hydrophilic, some places are hydrophobic, and they are intertwined.
  • the water falls on the surface of the object, the water naturally converges from the hydrophobic region to the hydrophilic region under the action of the tension to form water droplets, and the water droplets can adhere to the surface of the vertical object without slipping.
  • a hydrophilic film can be formed immediately, and the water will quickly spread without forming water droplets.
  • the reason is because the surfactant contained in the detergent is contained.
  • the interfacial tension of water is greatly reduced.
  • the invention ingeniously designs a plurality of injection schemes, and when necessary, the operation control switch sprays a hydrophilic cleaning liquid (referred to as a hydrophilic liquid) which has good hydrophilic wettability and can significantly reduce the interfacial tension of water. Retained on the rearview mirror and the window glass, the water droplets will immediately diffuse, run, and disappear, and can remain in the water for a period of time (more than 30 minutes).
  • a hydrophilic liquid referred to as a hydrophilic liquid
  • the hydrophilic liquid is stored in an existing scrubber kettle or a newly added kettle in the vehicle, the washing pump is activated by operating the control switch, and the hydrophilic liquid is transported through the catheter to the rear view mirror. And/or the nozzle on the window trim cover is sprayed onto the mirror mirror and the window glass.
  • the spray pattern and the design of the spray head are an important part of the present invention. Since the rear view mirror has various structures and installation positions, the present invention has designed a plurality of injection schemes, which may be one nozzle for two-direction injection, or multiple nozzles for different directions.
  • the spray head can be designed to be inlaid with a color, material, shape and shape that is inlaid with the part.
  • the mosaic is divided into an integral mosaic and a partial mosaic.
  • the integral mosaic means that the nozzle is mounted as a complete and independent component to another component.
  • the partial mosaic means that a part of the components forming the nozzle is directly formed on the other component, and other components are After molding, they are combined.
  • the nozzle can also be designed to be built-in, that is, the entire nozzle is directly formed on a certain part, which is simpler and more beautiful.
  • hydrophilic liquid with good hydrophilic wetting properties and a significant reduction in the interfacial tension of water is another indispensable important part of the present invention.
  • the use of a hydrophilic liquid to remove water drops has two functions: one is rapid and clean removal. The water droplets that have been formed, and the second is the pro-form formed by the hydrophilic liquid. The water film can maintain a long-term characteristic and can prevent the formation of water droplets for a certain period of time.
  • the currently used windshield washer fluid and the hydrophilic liquid required by the present invention have different performances due to different uses.
  • the existing windshield washer fluid mainly highlights the washing and dissolving functions, and the hydrophilic wettability is insufficient, even if the direct use of the cleaning liquid stock solution to remove the water drops is not satisfactory (the windshield washer fluid currently used on the vehicle is The cleaning liquid stock solution is diluted according to a certain ratio, and the cleaning liquid stock solution is not directly used.)
  • the hydrophilic liquid required by the present invention mainly highlights the hydrophilic and moisturizing functions. It is a good choice to improve the existing windshield washer fluid and unify the two.
  • a substance that acts as a hydrophilic wetting agent in a hydrophilic liquid and can significantly reduce the interfacial tension of water is a surfactant.
  • the existing windshield washer fluid already contains this component, but the concentration is low, and the variety may not Suitably, as long as the variety is properly selected and the concentration is properly formulated, the two cleaning solutions can be solved.
  • the hydrophilicity of the surfactant prepared with the hydrophilic liquid should be appropriate, not as strong as possible.
  • the HLB value is preferably 8 ⁇ 13, the hydrophilicity is too strong, and the water solubility is excessive, which will cause the surfactant to quickly follow the rain.
  • the time interval between the rear mirrors and the no longer forming water droplets is thus shortened.
  • the surfactant to be used should be mainly non-foaming nonionic surfactant, and a small amount of anionic surfactant should be compounded.
  • the surfactant should account for 0.3% ⁇ 5% by weight of the hydrophilic liquid. Degraded environmentally friendly varieties, at the same time must meet the relevant performance requirements of the windshield washer fluid.
  • the window glass may come down when it is not raining, in order to prevent the accidental touch control switch from injecting hydrophilic liquid into the cab (this will not only pollute the cab, but may scare the driver to cause safety hazards when driving at high speed).
  • the switch is designed to be controlled by the wiper switch. Only when the wiper switch is activated (when it rains, the window glass will close), the operation of the control switch is effective. It is also conceivable to install a sensor for detecting the state of the window glass in the door to prevent accidental injection of hydrophilic liquid into the cab.
  • the control switch can use a windshield washer switch to control the windshield washer switch to spray to the windshield glass when the wiper switch is turned off through a conversion circuit, and to control the rearview mirror and the vehicle when the wiper switch is turned on.
  • the window glass is sprayed, which saves a switch.
