Defroster vent opening and closing device for cars

摘要

This research is based on the front instrument panel, one side of the exhaust nozzle in the air jet nozzle, according to the extraction of the leaf spring, to form a switchable film cover of the automobile exhaust switch device. The existing debugger is in the state that the air outlet of the exhaust device formed in the vehicle has been opened, and there is foreign oil inside.The mouth is very easy, so all kinds of foreign matters are gradually blocked by the air mouth, and the air does not enter the car, so the heating efficiency is reduced, not only can not effectively remove the obstacles formed on the surface of the front glass window, so there are problems hindering the safe operation. A hinge that intersects according to the leaf spring is formed, and the negative film is covered on the terminal,Because of the elasticity of the above plate spring, the film cover is adsorbed on the extension of Indian paper, so as to switch on and off the exhaust air blast port, prevent the inflow of foreign matters, so as to make the air blast unblocked, at the same time, open the exhaust port of the driver's seat, and transfer the efficiency of hot air to the driver's seat, In order to improve and eliminate the obstacles of the driver's seat faster, it is an effective exhaust port switch device.
