Helmet and temperature regulation system

Abstract

A helmet with an outer shell has a buffer disposed inside the outer shell, a first flow channel positioned between a head of a wearer of the helmet and the buffer, and a second flow channel positioned in a groove formed in the buffer or at a portion where the buffer is partially absent. In the helmet, a heating medium containing at least partially a liquid flows through the first flow channel and the second flow channel.

1 . A helmet with an outer shell, comprising
 a buffer disposed inside the outer shell;   a first flow channel positioned between a head of a wearer of the helmet and the buffer; and   a second flow channel positioned in a groove formed in the buffer or at a portion where the buffer is partially absent, wherein   a heating medium containing at least partially a liquid flows through the first flow channel and the second flow channel.   
     
     
         2 . The helmet according to  claim 1 , wherein a diameter of the first flow channel is smaller than that of the second flow channel. 
     
     
         3 . The helmet according to  claim 1 , wherein the first flow channel is configured as a flexible micro flow channel. 
     
     
         4 . The helmet according to  claim 1 , wherein the second flow channel is formed into a tube shape. 
     
     
         5 . The helmet according to  claim 1 , wherein the heating medium contains aluminum nitride particles. 
     
     
         6 . The helmet according to  claim 1 , comprising a circulation pump configured to circulate the heating medium through at least one of the first flow channel and the second flow channel. 
     
     
         7 . The helmet according to  claim 1 , comprising a heat exchanger configured to exchange heat of the heating medium. 
     
     
         8 . The helmet according to  claim 6 , comprising a controller configured to regulate a temperature of the heating medium flowed through at least one of the first flow channel and the second flow channel by controlling at least one of the circulation pump and the heat exchanger. 
     
     
         9 . The helmet according to  claim 8 , wherein the controller regulates the temperature of the heating medium on the basis of a temperature related to the wearer. 
     
     
         10 . The helmet according to  claim 9 , wherein the controller regulates to reduce the temperature of the heating medium when the temperature related to the wearer is a first threshold or more. 
     
     
         11 . The helmet according to  claim 9 , wherein the controller regulates to increase the temperature of the heating medium when the temperature related to the wearer is a second threshold or less. 
     
     
         12 . The helmet according to  claim 9 , comprising a biological information sensor configured to detect the temperature related to the wearer. 
     
     
         13 . The helmet according to  claim 8 , wherein the controller regulates the temperature of the heating medium on the basis of the temperature related to the helmet. 
     
     
         14 . The helmet according to  claim 13 , wherein the controller regulates to reduce the temperature of the heating medium when the temperature related to the helmet is a third threshold or more. 
     
     
         15 . The helmet according to  claim 13 , wherein the controller regulates to increase the temperature of the heating medium when the temperature related to the helmet is a fourth threshold or less. 
     
     
         16 . The helmet according to  claim 13 , comprising an environmental information sensor configured to detect the temperature related to the helmet. 
     
     
         17 . A temperature regulation system, comprising:
 a helmet according to  claim 1 ;   at least one of a biological information sensor and an environmental information sensor; and   a controller configured to regulate a temperature of the heating medium on the basis of at least one of a temperature related to the wearer detected by the biological information sensor and a temperature related to the helmet detected by the environmental information sensor.   
     
     
         18 . A helmet with an outer shell; comprising:
 a buffer disposed inside the outer shell; and   a second flow channel positioned in a groove formed in the buffer or at a portion where the buffer is partially absent, wherein   a heating medium containing at least partially a liquid flows through the second flow channel.
