For example, the locking mechanism may be a latch-type stopper structure provided at the communication opening 111 of the base station body 110, and after the tray 131 is in place, the latch-type stopper structure is moved into the communication opening 111 and abuts against the outer wall surface of the tray 131 to prevent the tray from sliding outward. When cleaning is required, the tray 131 can be taken out by opening the locking mechanism (i.e., the bolt-type limiting structure).

Optionally, after the tray 131 is in place (i.e., reaches the installation position), the sliding groove 113 and the sliding member 135 may be in interference fit (the inner width of the sliding groove 113 is slightly smaller than the outer width of the sliding groove), and at this time, the sliding groove 113 and the sliding member 135 may abut against each other, so that the locking of the tray 131 may be limited. That is, the sliding slot 113 and the sliding member 135 are the locking mechanism. With the above arrangement, the internal structure of the base station 100 can be simplified, and the production cost can be saved.
