The block under test 4 may be set to: the measured block 4 is a convex part on the floater 2, namely the measured block 4 and the floater 2 are integrally formed.

As shown in fig. 2 and 3, the block 4 under test may also be configured to: the measured block 4 is a detachable block body, and the floater 2 is provided with a buckling part for assembling the measured block 4. The swing end of the floater 2 is provided with a first pressing piece 21d, and the first pressing piece 21d is used for fastening the measured block 4 in the fastening part.

The detection switch 3 can be a mechanical switch and comprises a moving contact, and the moving contact of the detection switch 3 can be touched when the detected block 4 rises in place. The detection switch 3 can also be a photoelectric sensor switch, when the detected block 4 rises to the right position, light rays (such as shielding, reflection and the like) can be infected, and the photoelectric sensor switch detects the light rays; the detection switch 3 can also be a Hall effect switch, the detected block 4 is magnetic or a metal piece, and the Hall effect switch detects when the detected block 4 rises to the right position (a certain Hall effect change occurs inside the Hall effect switch); the detected block 4 is magnetic, and the detection switch 3 is a magnetic reed switch; the detection switch 3 may be other proximity switches.

A reed switch, also known as a reed switch, is an electrical switch that is operated by an applied magnetic field. The basic type is to seal two magnetic reed sheets in a glass tube, wherein the two magnetic reed sheets are overlapped but have a small gap between them. When an external magnetic field exists, the two magnetic reed pieces are contacted and then conducted. Once the magnet is pulled away from the switch, the reed switch will return to its original position.

The detection switch 3 may be a press switch. The pressing switch is provided at the lower end of the substrate 1 as a detection switch 3 for detecting the block 4 to be detected.

The base plate 1 is provided with an upwardly convex cover inside which the float 2 is hinged. A push-piece switch may also be provided in the cover, with the projection of the float 2 as the corresponding location to be measured.

In manual operation, the two hands hold the two ends of the swinging member 21, the middle finger breaks the second pressing piece 21b outward, and the thumb pushes the floating block 22 downward. Alternatively, the insert is inserted into the opening and the thumb pushes the slider 22 downward.

A chassis component comprises a chassis and a switch structure; the base plate is provided with a water tank, and the base plate 1 is used as a cover plate of the water tank.

And the compressor is used for extracting air from the evaporator, compressing the refrigerant into high-temperature and high-pressure steam and providing power for the whole refrigeration loop. The condenser cools the high-temperature and high-pressure refrigerant steam, releases heat, and takes away condensation heat by an external air medium. The throttling device adjusts pressure through the size change of the pipeline, so that high-pressure refrigerant liquid is changed into low-pressure refrigerant liquid, and the liquid supply amount of the evaporator is adjusted. The evaporator absorbs heat through the gasification of the refrigerant, absorbs heat in the air, and meanwhile, water in the air is cooled and condensed into small water drops, so that the effects of dehumidification and cooling are achieved, and the refrigeration process is realized. The throttling device may be an electronic expansion valve capillary tube or a thermostatic expansion valve.
