7. A detection method of a household electrical appliance safety detection device, which is applicable to the household electrical appliance safety detection device as claimed in claim 6, and is characterized in that: the detection method of the household appliance safety detection device comprises the following specific steps:
step one: firstly, a gas water heater to be detected is placed on a placing plate (03), then an electric cylinder (04) works, so that the placing plate (03) is pushed to move towards the inside of a detection box (02), the placing plate (03) drives the gas water heater placed on the placing plate (03) to move towards the inside of the detection box (02), and the placing plate (03) and the detection box (02) are completely combined to form a complete box;
step two: when the placing plate (03) moves, the sliding plate (06) of the air inlet lock pipe device and the sliding plate (06) of the air outlet lock pipe device are driven to move simultaneously through the fixing rod (16), so that the connecting sleeve (10) is pushed to move towards one side direction in the detection box (02) through the guide rail plate (07) under the action of the guide rail rod (08), and the connecting sleeve (10) is spliced on a gas inlet and a gas outlet of the gas water heater, and the installation work of a pipeline is completed;
step three: when the gas water heater is placed on the placement plate (03), a gas inlet and a gas outlet of the gas water heater are placed on the clamping jaw (14), when the electric cylinder (04) pushes the placement plate (03) to move, the pushing frame (05) is pushed to move, so that two ends of the pushing frame (05) push the triangular jack block (13) to move upwards, the triangular jack block (13) can move upwards, and meanwhile, the upper end of the clamping jaw (14) is pushed to move towards the middle by the triangular jack block (13), and therefore the functions of clamping and centering an air inlet pipe and an air outlet pipe of the gas water heater are achieved;
step four: when the connecting sleeve (10) is communicated with the air inlet pipe and the air outlet pipe of the gas water heater, the air inlet and the air outlet of the gas water heater also push the compression ring (25) to compress the air bag (24), so that air in the air bag (24) enters the mounting block (22) through the second communicating pipe (18), and the clamping block (23) is pushed to extend out of the mounting block (22), so that the clamping block (23) can fixedly lock the air inlet pipe and the air outlet pipe of the gas water heater, and meanwhile, the air bag (24) is compressed and expanded to be clung to the air inlet pipe and the air outlet pipe of the water heater, so that sealing is realized;
step five: when placing board (03) and detecting box (02) and constituteing the closed box, adapter sleeve (10) and gas pipe (17) of air inlet lock pipe device just coincide and communicate this moment, valve (27) in gas pipe (17) can be attracted by magnet (29) this moment under the effect of magnetic force, thereby open valve (27), thereby gas in gas pipe (17) can get into adapter sleeve (10) through gas pipe (17), the intake pipe of rethread adapter sleeve (10) entering water heater, then in gas is discharged adapter sleeve (10) of air outlet lock pipe device through the gas outlet of water heater, detect the concentration of discharged gas through the gas concentration detector in adapter sleeve (10), thereby realize detecting the function of water heater pipeline.
