The distance between the two force-transmitting protrusions 230 is exactly the same as the diameter of the snap-in protrusion 520. The clamping protrusion 520 on the sliding member 500 corresponding to the operation opening 120 can be inserted into the clamping space 240, and the clamping protrusion 520 contacts with the two force transmission protrusions 230, so that the sliding member 500 can rotate relative to the clamping space 240 under the driving of the bearing disc 300, and when the corresponding sliding member 500 needs to be driven to slide, because the clamping protrusion 520 is limited between the two force transmission protrusions 230, when the door body 200 is pulled to open the operation opening 120, the clamping protrusion 520 can be driven to move outwards through the force transmission protrusion 230 located on the inner side, so that the sliding member 500 drives the storage tank 600 to leave the accommodating cavity 110 from the operation opening 120. When the operation opening 120 needs to be closed, the door body 200 is pushed inwards, the force transmission protrusion 230 on the outer side transmits force to the clamping protrusion 520, and the sliding piece 500 is driven to slide inwards to reset.

Further, the clamping space 240 has a first port 241 and a second port 242 arranged at an interval in the circumferential direction of the predetermined axis, the first port 241 and the second port 242 are both provided as reducing ports, the width of the first port 241 in the radial direction of the carrier tray 300 is gradually reduced in the direction from the first port 241 to the second port 242, and the width of the second port 242 in the radial direction of the carrier tray 300 is gradually increased in the direction from the first port 241 to the second port 242. So, a plurality of sliding parts 500 rotate together under the drive of bearing dish 300, receive the centrifugal force of certain size, even set up the damping layer and also can have the condition that sliding part 500 outwards slided the certain distance, under this situation, because two ports of joint space 240 are the reducing mouth, joint arch 520 can get into joint space 240 smoothly under the guide of first port 241 or second port 242, avoid joint arch 520 to produce with biography power arch 230 and interfere, the operation is more reliable and more stable.

Further, a moisture-proof door 530 is disposed on the sliding member 500, the moisture-proof door 530 is configured as an arc-shaped plate, and the moisture-proof door 530 is configured to move into an area surrounded by the operation opening 120 to close the operation opening 120 when the door body 200 is in a position to open the operation opening 120. Thus, when the storage tank 600 is taken and taken, although the door body 200 leaves the operation opening 120, the moisture-proof door 530 on the corresponding sliding piece 500 closes the operation opening 120, so that the phenomenon that the air environment in the accommodating cavity 110 is influenced by excessive external space entering the accommodating cavity 110 is avoided.

Referring to fig. 3, in the present embodiment, optionally, the drying assembly 400 includes a drying box having air holes, and the drying box is filled with drying particles. It should be noted that a replacement opening may be provided in the top plate 140, and a cover plate may be provided at the replacement opening, and the cover plate may open or close the replacement opening to replace the drying box from the replacement opening. For example, the drying box may be directly installed on the cover plate, and when the cover plate closes the replacement opening, the drying box is located in the accommodating chamber 110 to play a role of drying air in the accommodating chamber 110. It should be understood that the desiccant can be directly used in the prior art, and is not specifically described in this embodiment.

In this embodiment, it should be noted that the number of the storage tanks 600 is selected as needed, for example, four storage tanks 600 may be provided, correspondingly, the number of the sliding members 500 is four, and the four storage tanks 600 are respectively placed on the four sliding members 500.

In addition, in order to improve stability when the door 200 slides, a guide assembly may be provided between the door 200 and the housing 100, and the guide assembly may be a linear bearing or the like.
