A gear 42 is fixedly connected to the valve stem, a rack 43 is provided on the rear side of the gear 42, the rack 43 is meshed with the gear 42, and a control component is provided on the outer wall of the water storage tank 3.

[0022] In the specific implementation process, Figure 1 and Figure 2 As shown, the control component includes a protrusion with a mounting hole on the protrusion, in which an electric telescopic rod 44 is installed and connected, and a right-angle push plate 45 is fixedly connected to the telescopic end of the electric telescopic rod 44, and the right-angle push plate 45 is fixedly connected to one end of the rack 43.

[0023] It should be noted that the telescopic end of the electric telescopic rod 44 is extended for a period of time, so that the right-angle push plate 45 drives the rack 43 to move, drives the gear 42 meshing with it to rotate, drives the valve stem on the valve body 4 to rotate, and makes the valve body 4 automatically open for a period of time.

[0024] refer to Figure 1 and Figure 3 As shown, a visual window 5 is provided on the side wall of the water tank 3, a floating plate 6 is provided inside the water tank 3, a connecting rope 61 is connected to the upper side plate surface of the floating plate 6, and the other end of the connecting rope 61 is fixedly connected to a pulling plate 62.

[0025] It should be noted that the water stored in the water tank 3 gradually decreases, causing the floating plate 6 inside to move downward, driving the connecting rope 61 to slide relative to the sliding opening on the side wall of the water tank 3, and the other end of the connecting rope 61 drives the pulling plate 62 to slide upward relatively.

[0026] refer to Figure 1 and Figure 4 As shown, a sliding opening is provided on the upper side wall of the water storage tank 3, and the connecting rope 61 is slidably connected to the sliding opening.

[0028] It should be noted that: when the spring 71 undergoes elastic deformation and the pull plate 62 rises to abut against the pressure sensor 64 , the controller 2 controls the telescopic end of the electric telescopic rod 44 to extend for a period of time.

[0029] refer to Figure 1 and Figure 4 As shown, the mounting frame 63 is fixedly connected with a vertical rod 7, the pull plate 62 is slidably connected with the vertical rod 7, the vertical rod 7 is sleeved with a spring 71, one end of the spring 71 is connected with the pull plate 62, and the other end of the spring 71 is connected with the upper end of the mounting frame 63.

[0030] It should be noted that the spring 71 recovers its elastic deformation, so that the pull plate 62 can be moved in the reverse direction.

[0031] The working principle of a constant temperature and humidity regulating device for a clean room provided by the utility model is as follows: the water stored in the water tank 3 gradually decreases, so that the floating plate 6 inside it moves downward, driving the connecting rope 61 to slide relative to the sliding mouth on the side wall of the water tank 3, and the other end of the connecting rope 61 drives the pull plate 62 to slide upward relative to the vertical rod 7, so that the spring 71 undergoes elastic deformation. When the pull plate 62 rises to abut against the pressure sensor 64 (prior art), the controller 2 (prior art) controls the telescopic end of the electric telescopic rod 44 to extend for a period of time, so that the right-angle push plate 45 drives the rack 43 to move, drives the gear 42 meshing with it to rotate, drives the valve stem on the valve body 4 to rotate, so that the valve body 4 is automatically in an open state for a period of time, and can automatically complete the quantitative water addition inside the water tank 3, which is very convenient.
