When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. In the present invention, the terms "first" and "second" do not denote any particular quantity or order, but are merely used to distinguish names.

As shown in fig. 1, a sterilizing cabinet comprises: the device comprises a rack 10, an inner container 20, a drawer 30, an opening and closing driving assembly, a controller (not shown in the drawings), and a switch (not shown in the drawings), wherein the number of the inner containers 20, the number of the drawer 30, and the number of the opening and closing driving assembly are all plural, the inner containers 20, the number of the drawer 30, and the number of the opening and closing driving assembly are all one-to-one, and fig. 1 shows that the number of the inner containers 20, the number of the drawer 30, and the number of the opening and closing driving assembly are two, but not limited. The inner containers 20 are sequentially and longitudinally arranged on the rack 10, slide rails 60 are fixedly arranged on the rack 10 corresponding to the two sides of the inner containers 20 respectively, and the drawer 30 is slidably connected with the slide rails 60. The opening and closing driving assembly comprises a driving device 40 and a transmission device 50, the driving device 40 and the switch are electrically connected with the controller, the transmission device 50 is arranged in the middle of the bottom of the drawer 30, and the driving device 40 drives the drawer 30 to extend out of the inner container 20 or retract into the inner container 20 along the sliding rail 60 through the transmission device 50.

Because the transmission device 50 is arranged in the middle of the bottom of the drawer 30, in the process that the driving device 40 drives the drawer 30 to extend out of the inner container 20 or retract into the inner container 20 along the sliding rail 60 through the transmission device 50, the driving force of the driving device 40 is converted into acting force on the drawer 30 through the transmission device 50, so that when the acting force pushes the drawer 30 out of the inner container 20 or pulls the drawer 30 into the inner container 20, the two sides of the drawer 30 are stressed in balance, and the drawer 30 can move smoothly; moreover, above-mentioned sterilizer only needs to set up a set of drive assembly that opens and close and can realize the electronic of drawer 30 and open and close, effective reduction in production cost, and simultaneously, above-mentioned setting also can be that the inner structure of sterilizer is compacter.

In one embodiment, referring to fig. 2, the driving device 40 is a motor, the transmission device 50 includes a rack 51 and a gear 52, the gear 51 is fixedly connected to the middle of the bottom of the drawer, the gear 52 is engaged with the rack 51, the gear 52 is fixedly connected to a rotating shaft of the motor, the motor is disposed below the inner container 20, and the rotating shaft of the motor vertically penetrates through the bottom of the inner container 20. The transmission 50 is relatively inexpensive to produce.

Of course, the structure of the transmission device 50 can be various, for example, in another embodiment, the transmission device 50 includes a screw rod and a ball nut, the ball nut is fixedly connected to the middle of the bottom of the drawer 30, the ball nut is in threaded fit with the screw rod, one end of the screw rod is fixedly connected to the rotating shaft of the motor, and the motor is disposed at the inner bottom of the inner container 20. The transmission device 50 has high transmission precision, and is beneficial to accurately controlling the moving position of the drawer 30. (not shown in the drawings)

In one embodiment, referring to fig. 3, the disinfection cabinet further comprises a limit switch mechanism 70, wherein the limit switch mechanism 70 comprises a first trigger switch 71, a second trigger switch 72 and a trigger part 73, wherein the first trigger switch 71 and the second trigger switch 72 can be micro switches or proximity switches, and preferably, the first trigger switch 71 and the second trigger switch 72 are micro switches. The first trigger switch 71 and the second trigger switch 72 are electrically connected to the controller, respectively. The slide rail 60 includes an outer rail and an inner rail, the outer rail is fixedly disposed on the frame 10 and located at two sides of the inner container 20, and the inner rail is fixedly connected to the drawer 30. The first trigger switch 71 and the second trigger switch 72 may be respectively fixed on the inner container, the rack or the outer rail, the first trigger switch 71 and the second trigger switch 72 are respectively located at two ends of the outer rail, the trigger portion 73 is fixed on one end of the inner rail away from the drawer 30, the trigger portion 73 is used for triggering the first trigger switch 71 and the second trigger switch 72, and preferably, in order to reduce friction and wear between the trigger portion 73 and the first trigger switch 71 and between the trigger portion 73 and the second trigger switch 72, the trigger portion 73 is a soft contact, such as a rubber contact or a silica gel contact. When the drawer 30 is opened, and the driving device 40 drives the drawer 30 to move to the fully opened position, the triggering part 73 triggers the first triggering switch 71, the first triggering switch 71 feeds a triggering signal back to the controller, and the controller controls the driving device 40 to stop running after receiving the triggering signal; when the drawer 30 is closed and the driving device 40 drives the drawer 30 to move to the fully closed position, the triggering part 73 triggers the second triggering switch 72, the second triggering switch 72 feeds back a triggering signal to the controller, and the controller receives the triggering signal and controls the driving device 40 to stop running. The limit switch mechanism 70 prevents the driving device 40 from being operated for a long time, and protects the driving device 40.

In one embodiment, the switch is a mechanical switch or a tactile switch, preferably a tactile switch to facilitate user operation.
