Display equipment of gas contents

Abstract

A display equipment of gas contents include a sensing device mounted on an outlet of a gas supply and a display device mounted on a control panel of a gas stove. The sensing device has a floating member to be moved by a gas pressure of the gas supply. The display device has a switch and a display electrically connected to the switch. The switch is provided on the sensing device and in association with the floating member that the floating member may turn on or turn off the switch when the floating member is moved by the gas pressure, and the display shows relative information according to the switch. The display equipment of gas contents of the present invention may tell the remaining gas on the gas stove and whether there is a gas leakage in the system.

1 . A display equipment of gas contents comprising:
 a sensing device, which is mounted on an outlet of a gas supply, including a floating member to be moved by a gas pressure of the gas supply; and   a display device, which is mounted on a control panel of a gas stove, having a switch and a display electrically connected to the switch, wherein the switch is provided on the sensing device and in association with the floating member that the floating member may turn on or turn off the switch when the floating member is moved by the gas pressure, and the display shows relative information according to the switch.   
   
   
       2 . The display equipment of gas contents as defined in  claim 1 , wherein the sensing device further includes a valve member with a gas tunnel connecting the gas supply and the gas stove, and the floating member is movably provided on the valve with an end thereof extending into the gas tunnel. 
   
   
       3 . The display equipment of gas contents as defined in  claim 2 , wherein the floating member has a pressed surface facing the gas stove that the gas pressure is exerted on the pressed to move the floating member. 
   
   
       4 . The display equipment of gas contents as defined in  claim 3 , wherein the valve member includes a main body, in which the gas tunnel and a chamber communicated with the gas tunnel are provided, a fastener received in the chamber with a through hole, in which the floating member is movably received. 
   
   
       5 . The display equipment of gas contents as defined in  claim 4 , wherein the floating member is provided with a hole communicating the pressed surface with the chamber. 
   
   
       6 . The display equipment of gas contents as defined in  claim 4 , wherein the fastener further includes a bore communicated with the through hole and associated with the gas tunnel, and the floating member further includes a block associated with the gas tunnel, on which the pressed surface is formed, and an elastic member urging the block and a bottom end of the bore to urge the floating member against a stair portion in the gas tunnel when the floating member is not moved by the gas pressure. 
   
   
       7 . The display equipment of gas contents as defined in  claim 4 , wherein the valve member further includes a lid, which is mounted on the main body, having a recess facing the chamber, and the switch is received in the recess. 
   
   
       8 . The display equipment of gas contents as defined in  claim 6 , wherein the gas tunnel includes an input section and an output section, between which the chamber is provided. 
   
   
       9 . The display equipment of gas contents as defined in  claim 7 , further comprising an flexible annular sealing member provided on the stair portion and associated with the block, a ball received in an input section of the gas tunnel adjacent to the chamber to be moved to the sealing member when the gas pressure is suddenly raising up. 
   
   
       10 . The display equipment of gas contents as defined in  claim 1 , wherein the display device further includes a power supply electrically connected to the switch and the display.
