Helmet lens demister

Abstract

The present invention discloses a helmet lens demister, also including the lens (e.g., a snow or wind goggle) if being used independently. The helmet lens demister includes primarily a socket, a power supply device, a fan and fixing devices by which the demister is fixed on a predetermined location for defogging the lens. When defogging, a controller activates the power supply device to produce electricity and drive the fan. Then, the fan produces wind power to cause air convection. Therefore, a temperature in an inner space of the helmet lens will be close to a temperature of ambient environment and a temperature and humidity on an inner side of the lens can be adjusted; therefore, water molecules will not be attached on a side of the lens close to a human body. Moreover, as an entire structure is simple, the socket can be fixed freely, to improve the practicability.

Description

RELATED APPLICATION[0001]This application is a Continuation-In-Part of currently pending U.S. Pat. application Ser. No. 12 / 612,433 filed on Nov. 4, 2009.BACKGROUND OF THE INVENTION[0002]a) Field of the Invention[0003]The present invention relates to a demister and more particularly to a helmet lens demister which utilizes air convection to balance a temperature difference, so as to prevent from attachment of water molecules.[0004]b) Description of the Prior Art[0005]A motorcycle has already been one of most essential vehicles for short-ranged transportation of modern people. In order to protect safety of a rider, a helmet has become one of indispensable safety equipment. Therefore, whether in a sunny or rainy day, the rider has to wear the helmet to protect his or her safety; and all of the existing helmets will be attached with a piece of safety lens to keep alien objects from hitting on the rider's face and eyes upon riding the motorcycle. However, as the lens is covered, a temper...

AI Technical Summary

Benefits of technology

"The present invention is a helmet lens demister that uses air convection to balance temperature differences and adjust humidity on the lens to prevent water molecules from attaching to it. The demister is simple and compact, requires less electricity, and can be easily carried. It is also cost-effective and quickly defogges the lens to prevent fogging."

Problems solved by technology

However, as the lens is covered, a temperature inside the helmet will increase by hot air which is caused when the rider is breathing.

When the mist is produced on the helmet lens, a vision of the rider will be reduced, which will easily result in an accident.

This method can completely prevent the lens 10 from forming the mist; however, as this anti-fogging film 12 coating method will fail after a certain period of time, the anti-fogging film 12 has to be coated once after a certain period of time, in order to maintain the anti-fogging effect of the lens 10 of the helmet 1, which will be very inconvenient to the rider.

Nevertheless, as this method of utilizing the heating wires 22 will consume more electricity when activating, if a battery is used to supply electricity, power in the battery will be depleted very quickly and thus the battery has to be replaced constantly.

Therefore, the method of using the heating wires will very easily cause insufficient electricity.
