When the electric toothbrush is inserted into the mounting sleeve 23, the electronic tag 81 on the electric toothbrush sends a modulation signal to the reader-writer 82 through the antenna, the reader-writer 82 receives the modulation signal and converts the modulation signal into image information of a product, and finally the product information of the electric toothbrush is displayed on the display terminal 83, so that the product information of the electric toothbrush is displayed for audiences.

The working process of the embodiment is as follows: when the exhibition of the electric toothbrush is finished, the air pump 71 is started, the air in the reserved air box 73 is pumped into the reserved air cavity 721 through the air pump 71, so that the jacking air bag 25 is inflated with air to drive the electric toothbrush to be accommodated in the placing groove 21, at the moment, the air pressure in the reserved air box 73 is gradually reduced, the air pressure at one side, close to the reserved air box 73, of the first rubber sheet 741 is smaller than the air pressure at the other side, at the moment, the first abutting block 743 abuts against the first elastic sheet 742, so that the first rubber sheet 741 is not deformed, at the moment, the air in the accommodating air bag 6 is not lost, and along with the gradual flushing of the air in the jacking air bag 25, the air pressure in the reserved air box 73 is reduced to a certain value, the first elastic sheet 742 is deformed to drive one end, close to the axis of the communicating pipe 74, of the first rubber sheet 741 to deform towards the direction of the reserved air box 73, so that the communicating pipe 74 is communicated, and the, so that the display back plate 4 rotates the inflation and deflation system 7 to inflate the air into the jacking air bag 25 after the electric toothbrush is put in the placing groove 21, so that the jacking air bag 25 butts against the rotating arc plate, thereby driving the mounting sleeve 23 to rotate, leading the electric toothbrush to be collected in the placing groove 21, then the air pump 71 pumps the air in the air bag 6 to make the air bag 6 contract and pull the display backboard 4 to rotate until the display backboard 4 rotates to be horizontal, then the gas in the jacking gas cavity 722 enters the closed gas cavity 723, so that the annular gas bag 5 is filled with the gas until the annular gas bag 5 protrudes out of the display base 1 and abuts against the bottom surface of the display back plate 4, therefore, the electric toothbrush in the placing seat 2 and the placing groove 21 is isolated from the outside, the electric toothbrush exhibit is prevented from being exposed in the air during non-exhibiting time, the cleanness of the electric toothbrush is kept, and the exhibiting effect is guaranteed.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the invention may occur to those skilled in the art without departing from the principle of the invention, and are considered to be within the scope of the invention.
