A household gas pipeline timer

Abstract

The invention relates to a household gas pipeline timer. The household gas pipeline timer comprises a shell, wherein the shell is internally provided with an air inlet channel and an air outlet channel which are corresponding to each other; the channel wall of the air inlet channel is provided with a first connecting hole, the channel wall of the air outlet channel is provided with a second connecting hole, and a cavity is arranged above the air inlet channel and the air outlet channel; the cavity is internally provided with a timer, a rotary knob structure is arranged on a position, which is located at an opening of the cavity, above the timer, and a connecting device for controlling the communication of the first connecting hole of the air inlet channel and the second connecting hole of the air outlet channel is arranged between the space below the timer and the space above the air inlet channel and the air outlet channel. The household gas pipeline timer provided by the invention has a dual-seal guarantee, the sealing effect is good, and when the boiling food soup or boiling water on a gas stove overflows to extinguish the flames, the gas can still automatically cut out, thus the gas is prevented from leaking.

Description

technical field [0001] The invention relates to a timing device, in particular to a household gas pipeline timer. Background technique [0002] Gas has entered thousands of households and has brought great convenience to people's lives. If it is used improperly, it will also bring disasters. Gas leakage will be caused when the flame is extinguished, and people in the room can easily cause gas poisoning. Moreover, when cooking, if people are not next to the gas stove for a long time, the food will be overcooked. However, when the food is boiled or the soup boils and overflows to extinguish the flames, there are various timers on the market that control the opening and closing of the gas. Output.

[0002] Gas has entered thousands of households and has brought great convenience to people's lives. If it is used improperly, it will also bring disasters. Gas leakage will be caused when the flame is extinguished, and people in the room can easily cause gas poisoning. Moreover, when cooking, if people are not next to the gas stove for a long time, the food will be overcooked. However, when the food is boiled or the soup boils and overflows to extinguish the flames, there are various timers on the market that control the opening and closing of the gas. Output

[0003] Chinese patent publication number is CN2911483Y discloses a kind of gas cooker timer, and this gas cooker timer is made up of outlet joint, mechanical timer, connecting hose, shaft, rotating disk, pole and intake switch, and intake switch is made up of connecting pipe , the end cap arranged at one end of the connecting pipe, the plug arranged at the other end of the connecting pipe and the spring set on the connecting pipe. When the gas stove timer is turned on, the mechanical timer sets the set time and drives The pole swings, and the connecting pipe moves to one side under the drive of the pole. At this time, the plug is separated from the opening end of the intake switch, and the air inlet on the connecting pipe is connected to the connecting hose, and the gas enters the gas stove. In this kind of gas stove timer, only after the time set by the mechanical timer is over, that is, after the turntable is reset, the turntable can drive the pole to swing so as to realize the purpose of plugging the opening of the intake switch. When the boiling food soup or boiled water overflows to put out the flame, because the turntable is not reset, the gas is still on, which will cause gas leakage, which is likely to cause the risk of gas poisoning and explosion, and this kind of gas stove timer only Simply shut off the gas through a plug. When the sealing effect of the plug is not good due to long-term use, gas leakage will also occur if the plug is not checked and repaired in time, and the guarantee is not good enough.

[0004] Chinese patent publication number is that CN2921638Y discloses a kind of gas stove timer, and this gas stove timer and CN2911483Y disclose a kind of gas stove timer structure roughly the same, if in the middle of timing, the food soup that is boiling on the gas stove or When boiling water overflows to extinguish the flames, because the turntable is not reset and the gas is still on, it will cause gas leakage, which is likely to cause gas poisoning and explosion hazards, and this kind of gas stove timer only simply passes through a sealing ring. Close contact with the protruding ring to shut off the gas. When the sealing effect of the sealing ring is not good due to long-term use, if the repair is not timely checked, the phenomenon of gas leakage will also occur, and the guarantee is not good enough.
