Description

Technical Field

[0001] This utility model belongs to the field of gas alarm technology, specifically relating to a gas alarm with a split assembly. Background Technology

[0002] With social development and progress, natural gas and liquefied petroleum gas have become green energy sources used by households for boiling water and cooking. However, this decentralized use of gas also poses many safety hazards.

[0003] Furthermore, many atypical gas leak accidents occur every year, causing varying degrees of damage. In response to these gas leak accidents, the gas alarms currently in use are integrated gas alarms, meaning that the gas sensor probe is soldered onto a circuit board inside the alarm.

[0004] This type of integrated gas alarm has the following drawbacks.

[0005] 1. Currently, the two most commonly used combustible gases are liquefied petroleum gas (LPG) and natural gas. LPG is denser than air, so leaks will settle to the ground. Therefore, LPG gas alarms must be installed within 30 centimeters of the ground to provide timely warnings. However, this low installation point makes the internal electronic components susceptible to corrosion from water and dust, shortening their lifespan. Natural gas, on the other hand, is less dense than air, so leaks will rise to the roof. Therefore, natural gas alarms must be installed within 30 centimeters of the roof. This high installation point makes the detection button difficult to reach, leading to a lack of regular inspection. Consequently, the electrically operated shut-off valve will become inactive over time, and the valve core and shell may harden. If a natural gas leak occurs, the alarm will issue a shut-off command, but because the valve has hardened, it will not be able to close the gas line in time, rendering the alarm ineffective.

[0006] 2. The sensor probe on a gas alarm device is a gas-sensitive component, which is prone to aging due to environmental factors. Once the sensor probe loses its sensitivity, the gas alarm will lose its function. Since current gas alarms are integrated units, the entire unit must be replaced, thus increasing operating costs. Utility Model Content

[0007] The technical problem to be solved by this utility model is: in view of the shortcomings of the above-mentioned gas alarm, this split-type gas alarm is specially designed. The design concept is to separate the sensing probe from the main body of the gas alarm and add a control switch to improve the performance and increase the functions.

[0008] The technical solution adopted by this utility model to solve its technical problem is a split-type gas alarm, characterized in that: a split-type gas alarm includes a gas alarm body, an electric shut-off valve, and a sensor probe; the gas alarm body is fixedly mounted on the wall near the gas stove, and the electric shut-off valve is mounted on the gas pipeline; the sensor probe is divided into a liquefied petroleum gas (LPG) sensor probe and a natural gas sensor probe, with the LPG sensor probe mounted near the ground and the natural gas sensor probe mounted near the ceiling; the electric shut-off valve, the sensor probe, and the circuit board in the gas alarm body are electrically connected.

[0009] As described above, the gas alarm main body shell is equipped with an indicator light, a self-test / silence button, and a control switch; the gas alarm main body is equipped with a circuit board and a speaker, and the control module is installed on the circuit board; the indicator light, self-test / silence button, control switch, speaker and control module are electrically connected; ventilation holes are reserved on the gas alarm main body shell.

[0010] As mentioned above, the main casing of the gas alarm selectively reserves accessory control sockets, which are electrically connected to the circuit board. The accessory control sockets are also electrically connected to the exhaust fan. When the gas alarm is triggered, the electrical signal is transmitted to the exhaust fan through the accessory control sockets, and the exhaust fan then operates to expel the leaked gas outdoors.

[0011] As mentioned earlier, a signal transmitting module is selectively installed on the circuit board inside the gas alarm body. The signal transmitting module connects with the user's mobile terminal via the Internet to achieve interconnection and remote control.

[0012] As mentioned above, in order to protect the sensor probe, a protective shell is installed on the outside of the sensor probe, and the protective shell has reserved ventilation holes; in order to facilitate fixation, the protective shell has reserved fixing holes or is fitted with adsorption magnets.

[0013] As described above, a display screen is selectively installed on the main casing of the gas alarm. The display screen is electrically connected to the circuit board and displays the monitoring data and operating status of the gas alarm in a timely manner.

[0014] As described above, the electrical connection includes wired electrical connection and radio connection.

[0015] As described above, when indoor gas leaks and reaches a certain concentration, the sensor transmits a signal to the control module on the circuit board. The control module immediately sends commands to the speaker and indicator lights, which then issue audible and visual alarms. Simultaneously, it sends a command to the electric shut-off valve to close the gas line, causing the valve to cut off the gas supply. If an accessory control jack is provided, the control module sends a command to the exhaust fan, which then starts to expel the leaked combustible gas outdoors. If a signal transmitting module is provided, it transmits the information to a linked mobile terminal via the internet, allowing the user to remotely control the valve closure.

[0016] As mentioned above, the electric shut-off valve can also be used as a master control valve. When gas is needed, first turn on the control switch, and the control module sends an opening command to the electric shut-off valve, opening the gas pipeline and allowing gas to enter the gas stove in the room. After gas is used up, turn off the control switch, and the control module sends a closing command to the electric shut-off valve, keeping the indoor gas pipeline downstream of the electric shut-off valve at normal pressure, extending the service life of the indoor gas pipeline, and ensuring gas safety at the same time.

[0017] As mentioned above, the main body of the gas alarm is installed near the gas stove for easy monitoring of its working status. Simply press the detection / silence button on the outer casing of the gas alarm, and the gas alarm will automatically check whether its working status is normal. If it detects that the working status is abnormal, the sensor probe needs to be replaced or the components on the circuit board need to be repaired.

[0018] The beneficial effects of this utility model are: it is a split assembly and is not limited by the installation position, making it more convenient to use and more rational in structure; it is equipped with a control switch, which allows the electric shut-off valve to be used as a master control valve, increasing the frequency of opening and closing and avoiding the drawbacks of the electric shut-off valve becoming solidified over time.

[0024] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] like Figure 1 As shown in this embodiment, a split-type gas alarm is implemented. The split-type gas alarm includes a gas alarm body 1, an electric shut-off valve 2, and a sensor probe 3. The gas alarm body 1 is fixedly mounted on a wall 4 near the gas stove, and the electric shut-off valve 2 is mounted on a gas pipeline 5. The sensor probe 3 is divided into a liquefied petroleum gas (LPG) sensor probe and a natural gas sensor probe; the LPG sensor probe is mounted near the ground, and the natural gas sensor probe is mounted near the roof. The electric shut-off valve 2, the sensor probe 3, and the circuit board 15 in the gas alarm body 1 are electrically connected. The gas alarm body shell 11 selectively reserves an accessory control socket 19, which is electrically connected to the circuit board 15. The accessory control socket 19 is also electrically connected to an exhaust fan 6. When the gas alarm sounds, it transmits an electrical signal to the exhaust fan 6 through the accessory control socket 19, and the exhaust fan 6 then operates to discharge the leaked gas outdoors.

[0026] In this embodiment, a split-type gas alarm is fully installed in the kitchen. When indoor gas leaks and reaches a certain concentration, the sensor 3 transmits the sensing signal to the control module 17 on the circuit board 15. The control module 17 immediately sends commands to the speaker 16 and indicator light 12, which then issue an audible and visual alarm. Simultaneously, it sends a command to the electric shut-off valve 2 to close the gas circuit, and the electric shut-off valve 2 cuts off the gas pipeline 5. If an accessory control socket 19 is provided, the control module 17 sends a running command to the exhaust fan 6 through the accessory control socket 19, and the exhaust fan 6 starts to expel the leaked combustible gas outdoors. If a signal transmitting module 18 is provided, the signal transmitting module 18 will transmit information to the bound mobile terminal via the Internet, and the mobile phone holder can also remotely control the valve closure.

[0027] In this embodiment, the electric shut-off valve 2 can also be used as a main control valve. When gas is needed, the control switch 14 is turned on first, and the control module 17 sends an opening command to the electric shut-off valve 2, which opens the gas pipeline 5 and allows the gas stove in the room to be used. After the gas is used up, the control switch 14 is turned off, and the control module 17 sends a closing command to the electric shut-off valve 2, so that the indoor gas pipeline 5 downstream of the electric shut-off valve 2 is normally under normal pressure, which extends the service life of the indoor gas pipeline 5 and ensures gas safety.

[0028] like Figure 2 , 3 As shown in this embodiment, the gas alarm body 1 is an implementation of a split-type gas alarm. The gas alarm body housing 11 is equipped with an indicator light 12, a self-test / silence button 13, and a control switch 14. A circuit board 15 and a speaker 16 are assembled inside the gas alarm body 1. A control module 17 is mounted on the circuit board 15. The indicator light 12, self-test / silence button 13, control switch 14, and speaker 16 are electrically connected to the control module 17. Ventilation holes are provided on the gas alarm body housing 11. A display screen 7 is selectively installed on the gas alarm body housing 11. The display screen 7 is electrically connected to the circuit board 15 and displays the gas alarm's monitoring data and operating status in real time.

[0029] In this embodiment, the gas alarm body 1 is installed near the gas stove to facilitate the normal detection of the gas alarm's working status. Simply press the detection / silencing button 13 on the gas alarm body shell 11, and the gas alarm will automatically detect whether the working status is normal. If the working status is detected to be abnormal, the sensor probe 3 needs to be replaced or the components on the circuit board 15 need to be repaired.

[0030] In this embodiment, a signal transmitting module 18 is selectively installed on the circuit board 15 inside the gas alarm body 1. The signal transmitting module 18 is connected to the user's mobile terminal via the Internet to achieve interconnection and remote control.
