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.

1 . A helmet lens demister comprising:
 a socket, predetermined locations of which are provided with at least one fixing device;   at least one power supply device which is connected at the socket and is electrically connected with a controller; and   at least one fan which is connected at a pre-determined location of the socket and is electrically connected with the power supply device.   
     
     
         2 . The helmet lens demister according to  claim 1 , wherein a location of the socket where the fan is provided is transfixed with a vent which is connected to an air pipe, allowing external air to flow through. 
     
     
         3 . The helmet lens demister according to  claim 1 , wherein an air flow rate which is caused after an operation of the fan is larger than a respiration rate. 
     
     
         4 . The helmet lens demister according to  claim 1 , wherein the power supply device is an external circuit. 
     
     
         5 . The helmet lens demister according to  claim 1 , wherein the power supply device is a battery or solar energy. 
     
     
         6 . The helmet lens demister according to  claim 1 , wherein the lens is further a snow goggle or a wind goggle, which is used independently.
