A transmission belt 22 is provided between the two transmission wheels 21. When one of the rotating rods 2 rotates, the other rotating rod 2 will rotate accordingly through the transmission effect of the transmission wheel 21 and the transmission belt 22, which is convenient for controlling the two rotating rods 2 at the same time.

[0031] See also Figures 1 to 4 Specifically, an avoidance groove 31 is provided on the mounting seat 3, and one of the rotating rods 2 passes through the avoidance groove 31. A key groove is provided on the rotating rod 2 passing through the avoidance groove 31, and a spline (not shown in the figure) is provided on the output shaft of the driving member.

When the sliding cylinder 4 is pulled, the telescopic tube 42 can be extended and retracted to prevent the liquid in the heat exchange tube 13 from leaking out. The end of the sliding cylinder 4 away from the heat exchange tube 13 is rotatably connected to the connecting cylinder 43, and the connecting cylinder 43 is threadedly connected to the water inlet pipe or water outlet pipe of the adsorption air water intake unit.

[0035] See also Figures 1 to 5 Specifically, the telescopic tube 42 can be a common telescopic water pipe made of rubber or TPE, etc., which can prevent leakage while achieving telescopic effect.

The plug-in blocks are slidably arranged in the slots, and elastic members 6 are provided between the plug-in blocks and the slots). On the premise of ensuring the stability of several shells 1, the vibration to the inside of the shell 1 during installation or transportation can be reduced to avoid damage to the internal structure of the shell 1.

[0040] See also Figure 1 、 Figure 3 and Figure 6 Preferably, the elastic member 6 is a spring to provide return power.

[0041] See also Figure 1 、 Figure 3 and Figure 6 Preferably, there are four positioning rods 5 and four positioning holes on each shell 1, and the four positioning rods 5 or positioning holes are respectively distributed on the four corners of the shell 1, which can not only improve the stability between adjacent shells 1, but also save production costs.

[0042] See also Figures 1 to 6In actual use, first stack several shells 1, make the positioning rod 5 of one shell 1 cooperate with the positioning hole on the adjacent shell 1 (the distance between the two adjacent shells 1 can be changed by changing the length of the positioning rod 5 according to actual conditions), then connect the connecting block 14 to the rotating rod 2 respectively according to the distance between each shell 1, and finally connect the two connecting blocks 14 corresponding to each shell 1 to it (if the shell 1 and the connecting block 14 are connected with bolts, a pad or a pad can be installed between the shell 1 and the connecting block 14 to reduce the impact of the error on the connection, or other connection methods can be used for connection). When the height of several shells 1 needs to be changed or several shells 1 need to be removed, the rotating rod 2 can be rotated to separate the shell 1 from the rotating rod 2, and then the breathable cover 11 on the shell 1 can be removed to replace the adsorbent in the shell 1. If the distance between two adjacent shells 1 is not a regular distance, but is set specifically according to the environmental conditions, the installation method can also be changed. First, the two connecting blocks 14 corresponding to each shell 1 are connected to it, and then each shell 1 is connected to the rotating rod 2 respectively. During the connection process, the distance between the two adjacent shells 1 is adjusted so that the device can better adapt to the environment and improve the water intake effect.
