[0039] Please refer to Figure (6), in this embodiment, the position of the window is detected;

[0040] Further, the quick release seat 41 is fixedly installed on the left end of the front side of the window frame 6, the pressing block 8 is fixedly installed on the left end of the window sash 7, and the pressing block 8 corresponds to the position of the pressing button 4410;

[0041] Working principle: when the window sash 7 is closed, the pressing block 8 presses the button 4410 to the left. When the window sash is opened, the two metal pressing feet 446 are separated from the first electrode plate 4411 and the second electrode plate 4412. A voltage is applied between the first electrode plate 4411 and the second electrode plate 4412. If it is an open circuit, the window sash 7 is in an open state, and the processor 46 restarts timing and waits for the next detection. If it is a closed circuit, the window sash 7 is closed, and the processor 46 continues. Continue to apply vo...

[0043] Please refer to Figure (7), in this embodiment, the valve position is detected;

[0044] Further, the quick release seat 41 is fixedly installed on the left side of the valve 10, the pressing block 8 is fixedly installed on the front end of the valve 10, and the pressing block 8 corresponds to the position of the pressing button 4410;

[0045] Working principle: When the valve 10 is closed, the pressing block 8 pushes the pressing button 4410 to the left, and when the window sash is opened, the two metal pressing feet 446 are separated from the first electrode plate 4411 and the second electrode plate 4412. When the processor 46 A voltage is applied between the first electrode plate 4411 and the second electrode plate 4412. If it is an open circuit, the valve 10 is in an open state, and the processor 46 restarts timing and waits for the next detection. If it is a closed circuit, the valve 10 is closed, and the processor 46 Continue to apply voltage between the first ele...
