Today I will introduce a national invention authorized patent-a household gas meter with automatic gas leakage alarm. The patent was applied for by Chongqing Ruilibi Gas Equipment Co., Ltd., and was granted an authorization announcement on March 9, 2018.
Description of contentThe invention relates to the field of gas meters, in particular to a household gas meter with automatic alarm for gas leakage.
Background of the inventionNatural gas is a relatively safe gas. It does not contain carbon monoxide and is lighter than air. Once leaked, it will immediately diffuse upwards, and it is not easy to accumulate to form explosive gas. The safety is high. Therefore, most cities use natural gas as energy. However, in order to facilitate the use of natural gas, a gas meter needs to be installed in the home to count the gas consumption. The Chinese patent with the application number 201420525521 .4 discloses a gas meter, including a base meter, an air inlet and an air outlet are provided at the upper end of the base meter, and a mechanical display frame and an LCD display frame are provided on the base meter housing; The edge of the shell is provided with a wing plate for fixing the base surface, and a plurality of fastening screws are evenly arranged on the wing plate. The above patents have the disadvantages that they cannot only monitor the amount of gas used, and cannot alarm in time when gas leaks.
Summary of the inventionIn order to solve the above problems, the present invention provides a household gas meter with automatic alarm for gas leakage.
The figure is a spatial perspective view of the present invention. 1. Temperature sensor; 2. Voice alarm; 3. Mounting plate; 4. Electronic metering box; 5. Status indicator; 6. Outlet pipe; 7. Gas concentration detector; 8. Intake pipe; 9. Solenoid valve ; 10. Control box; 11. LCD screen; 12. Air quality detector; 13. Magnetic card installation slot; 14. Rechargeable lithium battery
The technical scheme adopted by the present invention is: a household gas meter with automatic gas leakage alarm, including an air inlet pipe, a mounting plate, and a liquid crystal display screen, an electromagnetic valve is provided on the air inlet pipe, and a gas concentration detection meter is provided beside the air inlet pipe; An air outlet pipe is arranged beside the concentration detector, an electronic metering box is arranged under the air outlet pipe, a mounting plate is arranged behind the electronic metering box, a control box is arranged in front of the electronic metering box, a status indicator light is arranged on the control box, and a status indicator light is arranged below the status indicator light There is a liquid crystal display, an air quality detector is arranged under the liquid crystal display, a temperature sensor is arranged under the air quality detector, a magnetic card installation slot is arranged under the temperature sensor, a rechargeable lithium battery is arranged under the magnetic card installation slot, and a control box A voice alarm is set on the side.
In the above structure, when the gas is used, the gas IC card is inserted into the magnetic card installation slot, the control box is automatically started, the control box controls the solenoid valve to open the gas, the gas concentration detector detects the gas concentration, and the electronic metering box automatically counts the amount of gas used , The gas concentration, pressure, gas consumption, air quality and indoor temperature information are displayed on the LCD screen. When the gas leaks or the room temperature is too high, the control box automatically controls the solenoid valve to close, and the voice alarm sends out a voice alarm to prevent There is danger.
In order to use fuel gas safely, the mounting plate is integrated with the electronic metering box injection molding, the intake pipe is installed on the electronic metering box through the pipe hoop, the solenoid valve is fixed on the intake pipe through the pipe hoop, and the outlet pipe is installed on the electronic metering box through the pipe hoop, A solenoid valve is also installed on the air outlet pipe. The gas concentration detector is fixed on the electronic metering box by screws, the control box is connected with the electronic metering box by screws, and the liquid crystal display is embedded on the control box. The air quality detector is embedded in the control box, the magnetic card installation slot is embedded in the control box, the rechargeable lithium battery is installed in the control box, and the voice alarm is installed on the side of the control box by screws.
