[0028] In this embodiment, an air inlet pipe 3 is provided on one side of the top of the gas meter housing 1, and the air inlet pipe 3 is at least used to transport gas from the main pipe to the gas meter housing 1; an exhaust pipe 2 is provided on one side of the top of the gas meter housing 1, and manual valves 4 are provided on the exhaust pipe 2 and the air inlet pipe 3.

[0029] In this embodiment, an actuator 5 installed on the air inlet pipe 3 is provided on the top of the gas meter housing 1, and the actuator 5 is at least used to realize automatic opening and closing of the air inlet pipe 3; Specifically, the actuator 5 includes a piston seat 52 fixedly sleeved on the outside of the intake pipe 3, a power member 53 is arranged below one side of the piston seat 52, a piston 57 is slidably inserted inside one side of the piston seat 52, and the intake pipe 3 is opened and closed by sliding the piston 57 inside the piston seat 52, and a transmission rod 55 is fixedly installed on the outer wall of one side of the piston 57, and the transmission rod 55 is used to drive the piston 57 to move, an end plate 54 is fixedly arranged at one end of the transmission rod 55, and a return spring 56 is sleeved on the outside of the transmission rod 55, and under the action of the return spring 56, the piston 57 is always inside the piston seat 52, forming a normally closed structure; Specifically, the power member 53 and the transmission rod 55 are sleeved with a protective cover 51 on the outside, and heat dissipation holes are arranged on both sides of the protective cover 51. The bottom of the protective cover 51 is fixed to the outer wall of the top of the gas meter housing 1. The protective cover 51 is used to protect the actuator 5.

[0030] In this embodiment, a closing thrust mechanism 10 located on one side of the actuator 5 is provided on the top of the gas meter housing 1, and the closing thrust mechanism 10 is at least used for returning the actuator 5; The closing thrust mechanism 10 includes a support 101 fixed on the gas meter housing 1, and a guide sleeve 102 is fixedly arranged on the top of the support 101, a retaining ring 103 is fixedly arranged on the outer wall of one side of the guide sleeve 102, a guide rod 104 is slidably inserted inside the retaining ring 103, a push plate 106 is fixedly installed at one end of the guide rod 104, and a compression spring 105 sleeved on the outside of the guide rod 104 is arranged between the push plate 106 and the retaining ring 103; When the power member 53 drives the end plate 54 to move, the end plate 54 will squeeze the push plate 106, so that the push plate 106 drives the guide rod 104 to slide inside the guide sleeve 102.

[0031] In this embodiment, a control module 6 is provided on the top of the gas meter housing 1, and a receiver 7 is installed on the control module 6; In this embodiment, a plurality of infrared sensors 8 and water level sensors 9; Specifically, a plurality of infrared sensors 8 can be arranged on the range hood above the gas stove. The infrared sensor 8 installed on the range hood can monitor whether there is a human body inside the kitchen. The water level sensor 9 is arranged on the gas water heater. The use of the gas water heater can be monitored through the water level sensor 9. When people use hot water, the hot water pipe is opened and the water level of the gas water heater drops. At this time, the water level sensor 9 transmits the signal of monitoring the water level drop to the receiver 7.

[0032] The infrared sensor 8 is at least used to monitor the presence of a human body, and the water level sensor 9 is at least used to monitor the water level change of the water tank inside the gas water heater, and transmit the received signal to the receiver 7 by wireless, and then the receiver 7 transmits it to the control module 6; Specifically, the water level sensor 9 includes an emitter 93 and a receiver 94 fixed inside a gas water heater tank 91.

The emitter 93 is located below the high line, and the receiver 94 is located above the high line and fixed on one side inner wall of the gas water heater tank 91. When the water level 92 is higher than the emitter 93, the emitter 93 emits light from underwater, which is directly projected in the water and refracted at the horizontal plane to hit the receiver 94. At this time, the emitter 93 and the receiver 94 are connected; When the water level line 92 is lower than the emitter 93, the emitter 93 emits a straight line of light. Since no refraction occurs, the light hits one side of the receiver 94. At this time, the emitter 93 and the receiver 94 are not conducting. When the emitter 93 and the receiver 94 are not conducting, it means that the water level inside the gas water heater has dropped, and there is a need for water indoors, that is, a signal is sent to the receiver 7, and the receiver 7 and the control module control the actuator 5, thereby opening the air inlet pipe 3 to deliver gas to the gas water heater to ensure the normal operation of the gas water heater.

[0033] Working principle: (1) The infrared sensor 8 is arranged on the range hood above the gas stove or other places in the room where the human body can be best monitored, and the water level sensor 9 is arranged on the gas water heater; (2) Using the infrared sensor 8 and the water level sensor 9, the indoor human body monitoring and the gas water heater usage monitoring are realized respectively; (3) The signal monitored in (2) is transmitted to the receiver 7, and then transmitted to the control module 6 by the receiver 7. The control module 6 controls the actuator 5 to determine whether the intake pipe 3 is open; (4) When the power part 53 of the actuator 5 receives a signal that someone is at home, the power part 53 starts, driving the transmission rod 55 to pull the piston 57 out from the inside of the piston seat 52, thereby opening the air intake pipe 3. When the power part 53 of the actuator 5 receives a signal that no one is at home, the power part 53 is controlled to close the air intake pipe 3, thereby preventing gas leakage.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
