Gas supply apparatus for a gas fired radiant heater

Abstract

A gas supply apparatus for a gas fired radiant heater has a compact structure, which includes a pressure regulator extending vertically and disposed at one side of an assembly seat, a switch button disposed at one side of the assembly seat, a temperature-control switch and a mercury switch provided on a horizontal platform extending from one side of the assembly seat, a gas pipe vertically extending in a substantially upright straight route from the assembly seat, a mixing tube securely connected on an upper end of the gas pipe by means of a clamping ring, a burner cap provided on an upper end of the mixing tube and a temperature sensor and an igniter respectively provided at one side of the burner cap, whereby the structure of the gas supply apparatus is optimized, and the working reliability and safety are ensured.

What is claimed is:  
     
         1 . A gas supply apparatus for a gas fired radiant heater, the gas supply apparatus comprising 
 a pressure regulator ( 10 );    an assembly seat ( 20 ) disposed at an upper position of the pressure regulator ( 10 ) and integrated with a gas conduit having a lower end in communication with an outlet of the pressure regulator ( 10 ), a switch button ( 22 ) provided at one side of the assembly seat ( 20 ), a mercury switch ( 24 ) and a temperature-control switch ( 26 ) provided on a platform extending from one side of the assembly seat ( 20 );    a gas pipe ( 30 ) having a lower end in communication with an upper end of the gas conduit of the assembly seat ( 20 ) and an upper end fixed with a nozzle ( 32 ) thereon;    a mixing tube ( 40 ) securely connected around the upper end of the gas pipe ( 30 );    a burner cap ( 50 ) provided on an upper end of the mixing tube ( 40 ) and having an igniter ( 52 ) provided at one side of the burner cap ( 50 ) and cooperated with the switch button ( 22 ), a temperature sensor ( 54 ) provided at one side of the burner cap ( 50 ) and cooperated with the temperature-control switch ( 26 ).    
     
     
         2 . The gas supply apparatus for the gas fired radiant heater as claimed in  claim 1 , wherein the switch button ( 22 ) disposed at one side of the assembly seat ( 20 ) is perpendicular to the extending direction of the gas pipe ( 30 ).  
     
     
         3 . The gas supply apparatus for the gas fired radiant heater as claimed in  claim 1 , wherein the gas pipe ( 30 ) extends vertically in a straight route.  
     
     
         4 . The gas supply apparatus for the gas fired radiant heater as claimed in  claim 1 , wherein the mixing tube ( 40 ) is securely connected with the upper end of the gas pipe ( 30 ) by means of a clamping ring ( 42 ).
