1. Field of the Invention
The present invention relates generally to a gas stove, and more particularly to a display equipment of gas contents.
2. Description of the Related Art
For aware of the remaining gas storage, a conventional gas barrel is equipped with a pressure sensor on an outlet. Such pressure sensor includes a housing, in which a film, a plug, a swing member are provided. The swing member has an indicating portion. When the film is pressed by gas pressure to move the plug, the swing member will be moved that the indicating portion is move to show user the information of remaining gas storage of the gas barrel.
Another pressure sensor is provided with an electronic device to show the information of remaining gas storage of the gas barrel by light or by audio.
In present days, barbecue is a very popular outdoors activity. Beside charcoal, there are more and more people using gas stoves for barbecue. Such gas stove has to connect a gas barrel through a hose, and the gas barrel usually is put away from the gas stove and received in a specific container for safety so that user, who stands around the gas stove, is hard to see the pressure sensor mounted on the gas barrel. Usually, user is aware of the gas is out when he/she find the fire of the gas stove is out.
The primary objective of the present invention is to provide a display equipment of gas contents, which may be mounted on a gas stove to be visible by user. The gas storage sensor may sense whether there is a gas leakage for safety.
According to the objective of the present invention, a display equipment of gas contents includes 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.
As shown in
The sensing device 12 includes a valve member 22, a floating member 24 and an elastic member 25. The valve member 22 includes a main body 26, a fastener 28, a lid 30 and a connector 32. The main body 26 has a gas tunnel 36 and a chamber 38 communicated with the gas tunnel 36. The gas tunnel 36 includes an input section 40 and an output section 42. The input section 40, which is connected to the chamber 38, has a stair portion 46 on a sidewall thereof. The fastener 28, which is mounted in the chamber 38, has a through hole 48 and a bore 50 communicated with the through hole 50. The fastener 28 is kept a distance away from a bottom of the chamber 38. The lid 30, which is mounted on a top of the main body 26 to seal the chamber 38, has a recess 52 associated with the chamber 38. The connector 32 is fitted to the main body 26 to connect the gas supply 1. The floating member 24 has a pole 54, which is movably received in the through hole 48 of the fastener 28. The pole 54 has a block 56 at a bottom end thereof, on which a pressed surface 58 is formed, and a hole 60 communicating the pressed surface 58 with the chamber 38. The elastic member 25 is a spiral spring urging the block 56 of the pole 54 and a bottom end of the bore 50 of the fastener 28 to urge the floating member 24 having the block 56 against the stair portion 46.
The display device 14 includes a switch 62, a display 64 and a power supply 66. The switch 62, which is a conventional microswitch received in the recess 52, has a driving point 68 touching a top of the floating member 24 to be moved by the floating member 24 for turning the switch 62 on or off. The display 64 is mounted on the case 3 of the gas stove 2 including a circuit board (not shown) and two lights 70, 72, which are light emitting diodes (LEDs), to emit green light and red light respectively by the command of the circuit board. The light 70 lights when the switch 62 is turned on, and the light 72 lights when the switch 62 is turned off. The circuit board and the lights 70, 72 are conventional devices, so we do not describe the detail here. The power supply 66 provides the switch 62 and the display 64 power.
The operation mode and function of the display equipment of gas contents 10 of the present invention are described hereunder:
The gas supply 1 provides gas into the input section 40 of the gas tunnel 36 to press the pole 54 on the pressed surface 58 that the floating member 24 will be moved upward when the gas pressure compresses the elastic member 25, as shown in
On the contrary, when the gas supply 1 almost runs out that the gas pressure is not enough to compress the elastic member 25, the floating member 24 will go down and the switch 62 is turned off that the light 70 of the display will be out and the light 72 lights (red light). If user sees the red light, it means the gas supply 1 are almost running out, he/she should replace a new one. The red light has another meaning, which is whether there is a gas leakage when user finds the gas supply 1 is full.
As shown in
In conclusion, the display device of the display equipment of gas contents of the present invention may be mounted on a control penal of the gas stove and the sensing device is mounted on the gas supply that the sensing device may sense the gas pressure and show the information on the display device on the gas stove to warm user who bakes or cooks on the gas stove. The display equipment of gas contents of the present invention also may warm user whether there is a gas leakage that provides a safer and convenient way in using gas stoves.
The description above is a few preferred embodiments of the present invention and the equivalence of the present invention is still in the scope of the claim of the present invention.
