[0002] With the development and progress of science and technology, people use more clean energy for convenient life, such as natural gas. By connecting natural gas to the stove to supply fuel for cooking, and also for providing hot water supply for the family, it is indispensable in everyone's life. However, the corresponding risk of natural gas leakage, explosion and other safety issues increases. Therefore, combustible gas alarm devices play a vital role in places such as homes. They are used to monitor the concentration of combustible gas in the air and issue an alarm when it exceeds the set threshold to remind people to take safety measures. However, there are some difficult-to-solve problems with combustible gas leak alarm devices: when natural gas leaks, there is only an alarm reminder function, which reminds through sound and then requires manual processing. If family members are out or sleeping, they are very likely to miss the best rescue time, thus causing losses. In addition, the windows and doors of most family kitchens are always open. After the natural gas leaks, it will drift to other rooms through the kitchen door, which is dangerous. Utility Model Content

[0014] The present invention will be further described below with reference to the accompanying drawings and some embodiments.

[0015] exist Figure 1-Figure 2In the embodiment, an indoor natural gas leakage protection and alarm device comprises a device body 1 and a range hood 4. The device body 1 is installed on the side of the range hood 4. The device body 1 comprises a natural gas detector 2 for monitoring gas leakage and sounding an alarm, and a pushing component 3 for driving the kitchen sliding door to close. The natural gas detector 2 is provided with a microcontroller 201. The output end of the natural gas detector 2 is connected to the input end of the microcontroller 201. The microcontroller 201 is provided with a wireless transmission end 202. The wireless transmission end 202 on the microcontroller 201 is wirelessly connected to the range hood 4 and the pushing component 3 respectively. The standard for natural gas leakage and transmission to each component can be set according to actual conditions. The larger the kitchen area, the larger the standard may be, and vice versa. When the natural gas detector 2 detects a natural gas leak, it transmits the leakage information to the microcontroller 201. The microcontroller 201 receives the information and transmits it to the range hood 4. Then the range hood 4 starts to extract the gas in the kitchen and discharges the leaked natural gas to the greatest extent. 3 includes a support block 301 for pushing the kitchen sliding door to close, a slide rail 302 for the support block 301 to slide, and a motor 303 for driving the support block 301 to slide on the slide rail 302. The motor 303 is connected to the support block 301 and the slide rail 302 respectively. The slide rail 302 is located above the sliding door and parallel to the sliding door. The support block 301 is located on the side of the sliding door and contacts the sliding door. When the natural gas detector 2 detects a natural gas leak, the leakage information is transmitted to the microcontroller 20 1. The microcontroller 201 receives the information and transmits it to the motor 303. The motor 303 drives the support block 301 to move on the slide rail 302, thereby closing the kitchen's sliding door and preventing natural gas from leaking into other rooms. Because the support block 301 is always located on one side of the sliding door, when the sliding door needs to be opened, it needs to be pushed open manually. When the force pushing the sliding door is greater than the resistance of the support block 301, the sliding door can be pushed, causing the support block 301 to move to its original position.

[0016] In this embodiment, a wireless receiving terminal 203 is provided on the range hood 4 and the motor 303, and the wireless receiving terminal 203 is wirelessly connected to the wireless transmitting terminal 202.

At the same time, the motor 303 drives the support block 301 to move, thereby pushing the sliding door to close.

[0017] In this embodiment, the device body 1 also includes an audible and visual alarm 204. The output end of the microcontroller 201 is connected to the input end of the audible and visual alarm 204. When the natural gas detector 2 detects a natural gas leak, the microcontroller 201 receives the information and transmits it to the audible and visual alarm 204. Then the audible and visual alarm 204 flashes and sounds an alarm.

[0018] In this embodiment, the microcontroller 201 is also wirelessly connected to a mobile terminal, which is an electronic product such as a mobile phone or tablet. The microcontroller 201 sends the natural gas leakage information to the mobile terminal via the wireless transmission terminal 202, so the natural gas leakage information can be remotely received from the mobile terminal.

[0019] In this embodiment, a battery 101 is respectively provided in the natural gas detector 2, the microcontroller 201, the motor 303, and the sound and light alarm 204. The output end of the battery 101 is respectively connected to the input end of the natural gas detector 2, the input end of the microcontroller 201, the input end of the motor 303, and the input end of the sound and light alarm 204.
