Thin-film demisting device

Abstract

The invention discloses a thin-film demisting device. The thin-film demisting device comprises a storage battery arranged in a helmet body, a solar cell panel arranged on the surface of the helmet body and rotary shafts arranged on two sides of an opening of the helmet mirror face, wherein a transparent thin film is wound between the rotary shafts, the rotary shafts are hollow rubber rollers, heating wires are arranged in the rotary shafts, one box body is respectively arranged above the rotary shafts and provided with a ventilation opening penetrating the whole box body towards the advancing direction, rotating blades facing the ventilation openings are arranged in the box bodies and fixedly connected onto the rotary shafts in a sleeved mode, the solar cell panel is connected with the storage battery, and the storage battery is connected with the heating wires. In the clear weather, the solar cell panel on the helmet can be utilized to charge the storage battery. When the thin-film demisting device is used in the rainy weather, the device is switched on to enable the storage battery to perform power supply and heating on the heating wires in the rotary shafts, heat of the heating wires is transferred to the rotary shafts, accordingly moisture on the transparent thin film can be effectively evaporated, and water mist is avoided.

Description

technical field [0001] The invention relates to a water brushing helmet used by a driver, in particular to a film defogging device for a water brushing helmet. Background technique [0002] When driving a motorcycle or electric bicycle, according to traffic regulations, in order to ensure driving safety, the driver must wear a helmet. However, when encountering rainy weather, the mirror surface of the helmet will be covered with water droplets, and the accumulation of water droplets will affect the driver's vision and seriously threaten the driver's personal safety. [0003] A kind of water brushing helmet is specially designed. The core of the design is to set a large opening on the mirror surface of the helmet, and set two rotating shafts on both sides of the opening, and a wiper against the rotating shaft is provided beside each rotating shaft. A transparent film is wound between the two rotating shafts, and the rotating shaft separates the transparent film into two laye...

[0003] A kind of water brushing helmet is specially designed. The core of the design is to set a large opening on the mirror surface of the helmet, and set two rotating shafts on both sides of the opening, and a wiper against the rotating shaft is provided beside each rotating shaft. A transparent film is wound between the two rotating shafts, and the rotating shaft separates the transparent film into two layers. The rotating shaft rotates under the action of an external force to drive the transparent film to rotate, and the rainwater falling on the transparent film will move with the film to the wiper for cleaning, so as to keep clear Sight, but when driving, there may be water mist on the film. Although the rain is scraped off, the water mist will also affect the line of sight, so how to drive the rotating shaft to scrape off the rain on the transparent film and eliminate the water mist is the current problem to be solved
