[0029] Before use, the fingerprint information and height information of different users are entered first, and this information is stored in the database of the controller 28. When in use, the user places his finger on the fingerprint module, and the fingerprint module feeds back the detected fingerprint information to the controller 28. The controller 28 compares the input fingerprint with the fingerprint in the database. If the comparison fails, the rotating cover 2 cannot be opened and the drawer 4 cannot be pulled out. If the information comparison is successful, the controller 28 determines the height information of the entered person and controls the electric telescopic rod a6 to work. The electric telescopic rod a6 can drive the table body 1 to move up and down, thereby realizing automatic adjustment of the height of the table body 1. At the same time, the controller 28 controls the electric telescopic rod b14 to work, and the electric telescopic rod b14 drives the rack 18 and the connecting frame 15 to move downward, and the rack 18 The movement drives the gear 20 to rotate, and the installation shaft 22 is driven to rotate under the coordinated transmission of the installation shaft 22 and the two sprockets 23. At this time, the rotating cover 2 is rotated to open, and the user can operate the display screen 3 through the keyboard 29 and the mouse 30. The connection frame 15 moves to drive the multiple positioning rods 16 to be respectively pulled out from the limiting holes 171 of the multiple limiting blocks 17, thereby releasing the limiting work on the drawer 4, so that the drawer 4 can be smoothly pulled out. After the work is completed, the user presses the closing button on the controller 28. At this time, the controller 28 controls the electric telescopic rod b14 to work again, and the electric telescopic rod b14 drives the rotating cover 2 to reset, and at this time, the multiple positioning rods 16 are also respectively inserted into the multiple limiting holes 171, thereby completing the limiting work on the multiple drawers 4 to prevent the drawers 4 from being pulled out by non-professionals.

[0030] Embodiment 2

[0031] like Figure 1 and Figure 2As shown, the present embodiment proposes a lifting multimedia podium. Compared with the first embodiment, in the present embodiment, a horizontal partition 7 is arranged inside the table body 1, and a vertical partition 8 is arranged on the horizontal partition 7. The cavity separated by the lower end of the horizontal partition 7 is a cavity a101, and the drawer 4 is installed on the inner side of the cavity a101; the cavities separated by the two sides of the vertical partition 8 are cavity b102 and cavity c103 respectively, and a through hole 1001 communicating with the inner side of the cavity b102 is opened on the table body 1. A water tank 9 and a pump 10 are installed on the inner side of c103, a nozzle 26 and a drying fan 27 are installed on the top of the inner wall of chamber b102, and proximity switches are installed on the nozzle 26 and the drying fan 27. The input end of the pump 10 is arranged on the inner side of the water tank 9, and the output end of the pump 10 is connected to the nozzle 26; a side box 11 is installed on the side of the table body 1, a water storage box 12 is slidably installed on the side box 11, and a drainage pipe 13 connected to the chamber b102 is arranged on the side box 11; the user takes the water out of the water tank 9, and the water storage box 12 is slidably installed on the side box 11, and the ... water storage box 12 is slidably installed on the side box 11, and the water storage box 12 is slidably installed on the side box 11, and the water storage box 12 is slidably installed on the side box 11, and the water storage box 12 is slidably installed on the side box 11, and the water storage box 12 is slidably installed on the side box 11, and After taking the chalk, the user's hands will be contaminated with a lot of dust. At this time, the user can extend his hand into the inner side of the chamber b102 through the through hole 1001, and first place the hand below the nozzle 26. At this time, the proximity switch on the nozzle 26 detects that an object is approaching and feeds back a signal to the controller 28. The controller 28 controls the pump 10 to work, and the pump 10 pumps the water inside the water tank 9 into the nozzle 26, and finally sprays it out through the nozzle 26 to achieve cleaning of the user's hands. After the cleaning work is completed, the hand is placed directly below the drying fan 27. The proximity switch on the drying fan 27 senses that an object is approaching and feeds back a signal to the controller 28. The controller 28 controls the drying fan 27 to start. The drying fan 27 generates hot air to dry the liquid on the hand. The cleaned waste liquid flows into the water storage box 12 through the drain pipe 13, and the water storage box 12 slides out from the inner side of the side box 11, so that the waste liquid stored in the water storage box 12 can be centrally cleaned.
