Heated shoe

Abstract

A heated shoe for generating heat by using hydrocarbon reaction with oxygen is disclosed. The heated shoe is capable to keep warm for long periods, giving out heat by itself, having a simple structure and low costs for parts. The heated shoe includes a shoe body defining a vent hole and a temperature control valve formed on the sole thereof. The sole defines a recess in which a partition defining a through hole is fixed. The partition divides the recess into two areas, one for receiving a fuel vessel of volatile fuel and the other for receiving an activated thermal conductor. Gas volatilized from the fuel penetrates through the through hole of the partition to contact the activated thermal conductor. The volatilized gas reacts with oxygen contained in air entering from the vent hole and generates heat with the catalysis caused by catalyst of the activated thermal conductor. The generated heat is transferred through a thermal pad to the whole shoe.

What is claimed is:  
     
         1 . A heated shoe, comprising: 
 a shoe body defining a vent hole through which surrounding air containing oxygen flows into the shoe and comprising a shoe in which a recess is defined;    a fuel vessel received in the recess for containing a fuel, the fuel being volatile to generate a fuel gas; and    an activated thermal conductor received in the recess for starting up reaction between the oxygen and fuel gas, which generates heat.    
     
     
         2 . The heated shoe as claimed in  claim 1 , wherein the fuel vessel and the activated thermal conductor are separated by a partition.  
     
     
         3 . The heated shoe as claimed in  claim 2 , wherein the partition defines at least a through hole.  
     
     
         4 . The heated shoe as claimed in  claim 1 , wherein the shoe body comprises a thermal pad.  
     
     
         5 . The heated shoe as claimed in  claim 1 , wherein the shoe body comprises a temperature control valve.  
     
     
         6 . The heated shoe as claimed in  claim 1 , wherein the shoe body comprises a fuel charge hole.  
     
     
         7 . The heated shoe as claimed in  claim 1 , wherein the shoe body comprises a temperature indicator.  
     
     
         8 . The heated shoe as claimed in  claim 1 , wherein the activated thermal conductor comprises a catalyst, a heating filament, a plurality of conducting wires and a thermal conducting plate.  
     
     
         9 . The heated shoe as claimed in  claim 8 , wherein the catalyst comprises a precious metal.  
     
     
         10 . The heated shoe as claimed in  claim 9 , wherein the precious metal comprises platinum.  
     
     
         11 . The heated shoe as claimed in  claim 8 , wherein the heating filament is made of nickel.  
     
     
         12 . The heated shoe as claimed in  claim 8 , wherein the conducting wires are connected to a power supply.  
     
     
         13 . The heated shoe as claimed in  claim 1 , wherein the shoe body comprises a power transmission hole for extension of the conducting wires therethrough.
