[0031] Working principle;

[0032] First, the bottom box 100 is fixed on the wall through the expansion plug through the connecting ring 103, and then the corresponding number of conduits 201 are taken out according to the number of areas to be monitored, and cut to the appropriate length, and then the sealing plugs 205 inserted in the inner cavity of the connecting pipe 210 are removed in turn, and the conduits 201 are sleeved on the surface of the connecting pipe 210 in turn, and the connection between the conduit 201 and the connecting pipe 210 is further clamped with the retaining spring 204, and the conduits 201 are placed in the areas to be monitored in turn, and then the plastic card 203 is connected to the surface of the conduit 201, and the protective sticker of the double-sided tape 208 is torn off and adhered to the wall to fix the conduit 201. At this time, the C-shaped block 202 is clamped to the connection between the gas pipe and the gas appliance. The gap is connected by a bolt 102 that penetrates one side of the fixing plate 400 and is threadedly connected to the surface of the other side fixing plate 400, so that the inner arc surface of the C-shaped block 202 completely fits the gap at the connection between the gas pipe and the gas appliance. When a leak occurs at the connection between the gas pipe and the gas appliance, the leaked gas passes through the exhaust fan 307 through the C-shaped block 202 and flows into the hollow block 301 through the conduit 201, and then flows into the detection box 304. The detection end of the gas sensor 303 in the detection box 304 detects an abnormal gas content in the air and feeds back the data to the single-chip microcomputer 302. The single-chip microcomputer 302 controls the sound and light alarm 300 to issue an early warning and sends a signal to the user's smart gas meter. The smart gas meter simultaneously closes the user's gas inlet pipeline valve.
