[0050] The working principle and use process of the present invention are as follows: first, the monitoring mechanism 2 is arranged inside the outer box 1, and then the outer box 1 is installed inside the kitchen, and the second fixed tube 23 in the monitoring mechanism 2 is fixedly installed on the top of the kitchen, or the second fixed tube 23 is installed close to the gas pipe. After installation, the power is turned on by the controller 219 and the driving motor 210 can be controlled to start by a mobile terminal or the like. After the driving motor 210 is started, the rotating disk 214 can be driven to rotate. When the rotating disk 214 rotates, the fixing rod 215 can be driven to rotate about the central axis of the rotating disk 214, so that the fixing rod 215 can The connecting rod 217 is pulled or pushed. Since the side of the connecting rod 217 away from the fixing rod 215 is movably connected to the fixing frame 218, the fixing frame 218 effectively drives the slide plate 213 to reciprocate left and right on the fixing plate 28. Since the limit block 211 fixed to the front and rear inner walls of the outer box 1 can limit the limit rod 212, and one end of the limit rod 212 is fixedly connected to one side of the slide plate 213, and the outer wall of the limit rod 212 is slidably connected to the inner wall of the limit block 211, the problem of the slide plate 213 being tilted and stuck is effectively avoided. When the slide plate 213 reciprocates left and right, when the slide plate 213 moves toward the third fixing tube 26 The slide plate 213 moves to one side away from the third fixed pipe 26, thereby effectively opening the first one-way valve 27 and closing the second one-way valve 221, so that the third fixed pipe 26 extracts the gas inside the fixed box 25, and the fixed box 25 extracts the internal gas of the first fixed pipe 21, and the gas inside the first fixed pipe 21 is discharged through the first fixed pipe 21. The gas inside the connecting tube 22 is extracted, and the connecting tube 22 extracts the gas inside the second fixed tube 23, and the gas inside the square box 24 is extracted through the second fixed tube 23. Since the sides of the square box 24 are provided with through holes 241, the rotating disk 214 can extract the external air, so as to facilitate the extraction of the external gas into the inside of the gas outlet pipe 29 and flow outward while being detected by the gas detection sensor 222. When the gas detection sensor 222 detects the gas, the controller 219 determines and controls the alarm device 220 to start and issue an alarm. Since the controller 219 is connected to the mobile terminal, the mobile terminal will also issue an alarm.

[0051] The filter mechanism 3 is arranged inside the fixed box 25, and the sponge 32 is placed inside the side of the ICBC board 31 close to the outer box 1, and the ICBC board 31 is placed inside the fixed box 25, and then placed inside the slot 33 through the baffle 34. Since the baffle 34 is magnetically connected with the magnet 36, the baffle 34 is effectively fixed inside the slot 33, and the ICBC board 31 can be limited, so that the ICBC board 31 falls downward. Therefore, the gas passing through the fixed box 25 will be filtered by the ICBC board 31 and then pass through the sponge 32, and then enter the inner part of the outer box 1 through the third fixed tube 26. When it is necessary to clean the ICBC board 31 and the sponge 32, the baffle 34 is driven by pulling the pull ring 35, and then the ICBC board 31 can drive the sponge 32 to fall downward;

[0052] By setting up the mounting mechanism 4, since the first mounting hole 44 and the second mounting hole 45 are opened on the mounting frame 42, the bolts are inserted from the inside of the first mounting hole 44 and inserted from the second mounting hole 45 and fixed to the wall of the kitchen, and the second mounting hole 45 can facilitate the hiding of the bolts. The plug block 41 is fixedly connected to the top of the back side of the outer box 1, and the plug block 41 is inserted into the inside of the mounting frame 42. The cushion block 43 is fixedly connected to the bottom of the outer wall of the back side of the outer box 1, so that the outer box 1 can be conveniently placed parallel to the wall.

A method for using a gas leakage monitoring device based on smart gas, according to the gas leakage monitoring device based on smart gas according to claim 8, characterized in that: The method of use comprises the following steps: Step 1: Installing the outer box (1) inside the kitchen; The second fixed pipe (23) in the monitoring mechanism (2) is fixedly installed on the top of the kitchen, or installed close to the gas pipe; Turning on the power supply of the controller (219), and starting the driving motor (210) through the mobile terminal; After the driving motor (210) is started, it drives the rotating disk (214) to rotate, thereby driving the fixing rod (215) to rotate about the central axis of the rotating disk (214); The fixed rod (215) pulls or pushes the connecting rod (217), and the connecting rod (217) drives the movement of the slide plate (213) to be limited by the limit block (211) and the limit rod (212), so as to prevent the slide plate (213) from tilting and getting stuck; When the slide plate (213) moves toward the side of the third fixed pipe (26), the first one-way valve (27) is closed, the second one-way valve (221) is opened, and the gas moves downward from the gas outlet pipe (29) and is detected by the gas detection sensor (222); When the slide plate (213) moves toward a side away from the third fixed tube (26), the first one-way valve (27) opens, the second one-way valve (221) closes, and the third fixed tube (26) extracts gas from the interior of the fixed box (25); The fixed box (25) extracts gas from the inside of the first fixed tube (21), the first fixed tube (21) extracts gas from the inside of the connecting tube (22), the connecting tube (22) extracts gas from the inside of the second fixed tube (23), and the second fixed tube (23) extracts gas from the inside of the square box (24); The square box (24) draws in external air through the through hole (241), and the gas flows out through the gas outlet pipe (29) and is detected by the gas detection sensor (222); When the gas detection sensor (222) detects gas, the controller (219) determines and controls the early warning device (220) to start, and the mobile terminal also issues an early warning; Step 2: Placing the ICBC board (31) inside the fixing box (25); Insert the baffle (34) into the slot (33), the baffle (34) is magnetically connected to the magnet (36), the baffle (34) is fixed and the ICBC board (31) is limited; After being filtered by the IC board (31) and the sponge (32), the gas enters the interior of the outer box (1) through the third fixed pipe (26); When the IC board (31) and the sponge (32) need to be cleaned, the pull ring (35) is pulled to drive the baffle (34), and the IC board (31) and the sponge (32) can fall downwards for cleaning; Step 3: A first mounting hole (44) and a second mounting hole (45) are provided on the mounting frame (42); The bolt is inserted through the first mounting hole (44) and the second mounting hole (45) to fix it on the kitchen wall; Insert the insert block (41) on the back of the outer box (1) into the installation frame (42); A cushion block (43) is fixedly connected to the bottom of the back of the outer box (1) so that the outer box (1) is placed parallel to the wall.
