Technical Field
[0001] The invention relates to the technical field of combustible gas detection and alarm, and in particular to an intelligent household gas safety detection and alarm device. Background Art
[0002] With the development of science and technology and the continuous improvement of people's living standards, as well as the gas industry's development towards environmental protection, energy saving, safety and low prices, gas stoves, as a necessary kitchen appliance, have higher and higher requirements in terms of practicality, safety and multi-function. Nowadays, most household gas is natural gas. As a gaseous fuel, natural gas is mainly composed of methane, which is not toxic to the human body. However, if the human body inhales excessive air containing natural gas, it will cause insufficient oxygen in the gas inhaled by the human body, which may even endanger life in severe cases. When the gas leaks and mixes with the air, an explosion may occur when the gas ratio reaches a certain range. Among them, the connection between the natural gas pipeline and the gas meter is the most prone to leakage.
[0003] Existing household gas safety detection and alarm devices cannot quickly detect and alarm the connection between the natural gas pipeline and the gas meter, which causes a large amount of methane to enter the indoor air, which can easily cause insufficient oxygen in the gas inhaled by the human body, or the user uses open flames without knowing it, which can easily cause explosions and pose safety hazards. Faced with so many gas safety accidents, it is not feasible to solve them from the root. The only way is to establish an accurate and effective prevention mechanism to issue an early warning before the gas leak causes harm, providing people with time and relevant measures to avoid accidents.

The gas detection box 10 is externally installed with a second detector 29 for detecting indoor methane concentration. The second detector 29 is connected to the control panel 11 by line.
[0028] Further, such as Figure 1 As shown, an air intake valve 18 and a stove valve 19 are respectively connected to both ends of the gas pipeline 16 , and both the air intake valve 18 and the stove valve 19 are connected to the control panel 11 by lines.
[0029] Further, such as Figure 5-7 As shown, the circular tube 15 is located on the outside of the gas pipeline 16, a sealing assembly is provided on the inner side of one end of the circular tube 15, and a sealing ring 27 is provided on the inner side of the other end of the circular tube 15, the sealing assembly is located between the inner side of the circular tube 15 and the outer side of the gas pipeline 16, and the sealing ring 27 is located between the inner side of the circular tube 15 and the outer side of the gas pipeline 16.

The outer ring 24 is fixed on the inner side of the circular tube 15, the U-shaped ring 25 is fixed on the inner side of the outer ring 24, the inner ring 23 is fixed on the inner side of the U-shaped ring 25, the inner side of the inner ring 23 is in frictional contact with the outer side of the gas pipeline 16, a plurality of support blocks 26 are arranged at intervals on the inner side of the U-shaped ring 25, and the opening of the U-shaped ring 25 faces one side of the gas detection box 10.
[0031] Further, such as Figure 5-7 As shown, a plurality of support blocks 26 are arranged in a circular array inside the U-shaped ring 25 as a group, and each group of support blocks 26 is spaced apart in the axial direction. The inner ring 23, the outer ring 24, the U-shaped ring 25 and the support blocks 26 are all made of rubber.
[0032] Further, such as Figure 7 As shown, a groove 28 is provided on one side of each sealing ring 27 facing the gas detection box 10 , and each sealing ring 27 is made of fluororubber.
[0033] In the initial state, the plurality of support blocks 26 are in an extruded state, and the inner side of the inner ring 23 is closely fitted to the outer side of the gas pipeline 16 by the extruded state of the plurality of support blocks 26 .
[0034] When in use, the control panel 11 is connected to the gas system of the gas company through the Internet of Things, so that the staff can control the gas safety detection alarm device through the control panel 11, and can cut off the gas pipeline 16 of the user who owes fees. The staff can see the value displayed on the gas meter 17 through the transparent window 12.
[0035] Natural gas leakage is usually located at the connection between the gas meter 17 and the gas pipeline 16, and there are also natural gas leaks in other locations. Therefore, the methane concentration in the gas detection box 10 is monitored in real time by the first detector 22, and the detected data is transmitted to the control panel 11, and the methane concentration inside the gas detection box 10 is displayed on the display module on the control panel 11; the indoor methane concentration is then monitored in real time by the second detector 29, and the detected data is transmitted to the control panel 11, and the methane concentration inside the gas detection box 10 is displayed on the display module on the control panel 11, so that the staff can compare the methane concentration inside the gas detection box 10 with that in the room, and quickly find the location of the natural gas leak.
[0036] When natural gas leaks at the connection between the gas meter 17 and the gas pipeline 16, the methane concentration in the gas detection box 10 continues to rise. At this time, the gas in the gas detection box 10 continues to increase, causing the air in the gas detection box 10 to move into the two circular tubes 15, first through the outer side of the outer ring 24 fixedly connected to the inner side of the circular tube 15, and the inner side of the inner ring 23 is tightly fitted with the outer side of the gas pipeline 16, so that most of the gas in the circular tube 15 enters the U-shaped ring 25, and the gas in the U-shaped ring 25 continues to increase, causing the U-shaped ring 25 to collide, and the U-shaped ring 25 collides with a number of support blocks 26 to squeeze and produce The elastic force makes the inside of the inner ring 23 further fit closely with the outside of the gas pipeline 16, reducing the gas overflow in the round tube 15, and then the sealing ring 27 is located between the round tube 15 and the gas pipeline 16, thereby further reducing the gas overflow in the round tube 15, and finally the gas in the round tube 15 enters the groove 28 through the groove 28, so that the inner side of the groove 28 fits closely with the outer side of the gas pipeline 16, and the outer side of the groove 28 fits closely with the inner side of the round tube 15, so that the sealing assembly and the sealing ring 27 perform a double sealing effect on the round tube 15 and the gas pipeline 16.
[0037] When the first detector 22 detects that the methane concentration in the gas detection box 10 reaches the set value, the control module in the control panel 11 quickly closes the air intake valve 18 and the stove valve 19, and lights up the indicator light 13; at this time, the control module in the control panel 11 controls the solenoid valve 21 to open and the exhaust fan at the outer end of the exhaust pipe 20 to start, and the exhaust fan starts to quickly discharge the gas in the gas detection box 10 through the exhaust pipe 20 to the outside, so as to quickly reduce the concentration of methane through the outdoor air flow and reduce the degree of harm. The control panel 11 also transmits real-time data to the gas system of the gas company.
[0038] When the location of the natural gas leak is outside the gas detection box 10, the methane concentration in the room is detected by the second detector 29. When the second detector 29 detects that the methane concentration in the room reaches the set value, the control module in the control panel 11 quickly closes the air intake valve 18 and the stove valve 19, and lights up the indicator light 13, and the buzzer 14 sounds an alarm to remind nearby people to take corresponding safety measures.
