[0039] Working principle: When it is necessary to detect whether there is liquid leakage at a certain position of the device, place the gas near it, and then pull the pull handle 14 to move the clamping block 15 towards the middle and compress the second spring 12 so that the clamping block 15 disengages from the clamping groove 10, thereby taking out the cover plate 26 from the detection box 8. Then, rotate the rotating block 19, place the absorbent paper on the inner wall of the detection box 8, and then rotate the rotating block 19 to clamp it to ensure that its upper and lower sides are respectively in contact with the first electrode 9 and the second electrode 18. Then, press the cover plate 26 towards the detection box 8 so that the clamping block 15 is engaged with the clamping groove 10 again. Then, start the exhaust fan 6 to draw the surrounding gas into the detection box 8 through the hollow tube 1, the through tube 3, and the connecting tube 7. If there is liquid leakage, the surrounding humidity is relatively high, making the absorbent paper in the detection box 8 wet and conducting the first electrode 9 and the second electrode 18, thus emitting an alarm.

[0040] When installing, first fix the installation block (201) at the position to be installed through the installation plate (20). Then, insert the T-shaped block (205) into the sliding groove (202) and at the same time make the front side of the T-shaped block (205) slide along the inner wall of the guide groove (203) to limit its position. When it is pressed down to a certain height, the chamfer of the T-shaped block (205) will fit with the chamfer of the sliding block (204), and at the same time, the sliding block (204) will be moved outward to compress the first spring (207). When the T-shaped block (205) reaches the lowest point, the sliding block (204) will be reset due to the elastic force of the first spring (207) to engage the T-shaped block (205) to complete the installation.
