In addition, the backboard 130 is provided with a charging interface 800, and the charging interface 800 may be a USB interface or a corresponding adapter device, but not limited thereto.

The working principle of the device is as follows:

(1) first, after the device is connected to a USB interface through a USB cable to supply power, the device is in a standby state, and the infrared pyroelectric sensor 600 starts to operate.

(2) When a user approaches the sensing range of the illustrated infrared pyroelectric sensor 600, a signal is transmitted to the circuit board 200. After program operation, a control signal is firstly output to the steering engine 300, the steering engine 300 rolls and contracts the connecting line to drive the front cover plate to rotate around the rotating shaft of the front cover plate and the upper cover plate 110 and slowly lift up until the front cover plate is parallel to the upper cover plate 110.

(3) Next, the circuit board 200 outputs a control signal to the motor 500 on the rear baffle 130, drives the motor 500 to work, and drives the upper cover plate 110, the front baffle 120 and the two side plates 140 to move toward one side of the rear baffle 130 along the horizontal direction by engaging the plastic gear 510 of the output shaft of the motor 500 with the racks 141 on the inner sides of the two side plates 140, until the program setting time on the circuit board 200 is over, and the end of the rack 141 is reached, and the movement is stopped.

(4) In the above movement process, the plastic tank chain 400 will bend from the initial straight state to the opposite direction along with the movement of the upper cover plate 110, so as to restrain the control line (not shown) of the steering engine and avoid interfering with the back baffle 130 and the keyboard itself.

(5) When a user leaves the sensing range of the infrared pyroelectric sensor 600, the infrared pyroelectric sensor 600 also senses and transmits a signal to the circuit board 200, if the signal sensed and transmitted by the infrared pyroelectric sensor 600 is not received again within a certain time (i.e., the sensor does not sense the proximity trigger of the user again), the circuit board 200 outputs a control signal to the motor 500, the motor 500 is driven to run in the reverse direction, and the upper cover plate 110, the front baffle plate 120 and the two side plates 140 are driven to cooperate with the rollers 142 below the two side plates 140 to realize resetting.

(6) Finally, when the time is set by the program and the output shaft reaches the front end of the rack 141, the circuit board 200 outputs a control signal to reversely move to the steering engine 300, the connecting line is zoomed, the front baffle 120 slowly rotates downwards until the front baffle is vertically attached to the upper cover plate 110, and the tank chain reversely stretches to move, so that the resetting is realized.

Keyboard dust keeper, drive upper cover plate 110, preceding baffle 120 and two curb plates 140 through circuit board 200 control motor 500 and steering wheel 300 and remove, realize that automatic dust-proof box is automatic to open the closure to through infrared pyroelectric sensor 600, the signal in the real-time reception device response scope, intelligent control device work.

The above is only a specific embodiment of the present invention, but the design concept of the present invention is not limited to this, and the present invention is to be modified immaterial by this concept, and all should belong to the act of infringing the protection scope of the present invention.
