[0052] In this embodiment, a slide groove 5 is provided on the surface of the interactive operation table 1, a rear baffle 7 is integrally formed at one end of the interactive operation table 1, and an electric telescopic rod 37 is screwed on the surface of the rear baffle 7. One end of the electric telescopic rod 37 is fixedly connected to the surface of the client 2, a fixing plate 6 is welded at the bottom of the interactive operation table 1, and the client 2 is pressed on the surface of the interactive operation table 1. The client 2 includes a host housing 14, a first touch screen 16, and a second touch screen 20. The first touch screen 16 is installed on the top of the host housing 14, and sliding bars 15 are attached to both sides of the bottom of the host housing 14. An air inlet 22 and an exhaust port 23 are respectively provided on both sides of the bottom of the host housing 14, and a fixing frame 17 is screwed on one end of the side of the host housing 14. A rotating plate 18 is screwed to the rear end of the second touch screen 20, and a bottom rotating shaft 19 is integrally formed at the bottom of the rotating plate 18. Top rotating shafts 21 are inserted on both sides of the top of the rotating plate 18. The bottom rotating shaft 19 is embedded in the inner side of the fixing frame 17, and the sliding bar 15 is embedded in the inside of the slide groove 5.

[0053] Specifically, each client 2 is installed and placed on the interactive operation table 1, and subsequent students directly control the client 2 on the interactive operation table 1 to carry out subsequent experiments, learning, viewing, etc., and the rear end of the client 2 is pulled by the electric telescopic rod 37, so when in use, the second touch screen 20 is manually lifted upward, and then the first touch screen 16 is pulled to fully unfold the client 2. After unfolding, the first touch screen 16 and the second touch screen 20 can be used for learning operations at the same time, and after use, the client 2 can be manually closed. When the electric telescopic rod 37 is used to close the main body 14, the electric telescopic rod 37 is directly started to retract and the main body housing 14 is pulled backward. During this process, the second touch screen 20 moves up first, and as the first touch screen 16 passes over the output vertical plane of the guide mechanism 3, the second touch screen 20 is flipped toward the front end, and after moving downward by its own gravity, the first touch screen 16 continues to move backward until the first touch screen 16 is pressed on the first touch screen 16 to complete the folding and storage process.

[0054] In this embodiment, the heat dissipation system 4 includes a heat dissipation cavity 8 and an air intake fan 9. The air intake fan 9 is screwed on one side of the heat dissipation cavity 8. An exhaust hole 10 is provided on the other side of the heat dissipation cavity 8. The surface of the interactive operation table 1 is paved with a dustproof net 11 and a dust removal channel 12 is provided. The bottom of the dust removal channel 12 is provided with an inclined plate 13. One end of the interior of the dust removal channel 12 is partially connected to the exhaust hole 10. The air intake fan 9 blows external air into the surface of the dustproof net 11. The heat dissipation system 4 is externally placed, and can only provide heat dissipation treatment for the inside of the host housing 14 during the use and learning process of the client 2. In the closed state, the host housing 14 can be directly completely sealed to ensure higher sealing when not in use for a long time, and also avoid the problem of students forgetting to close it.

[0055] Specifically, in the use state, such as Figure 1 As shown, after the air intake fan 9 is started, the external airflow is blown from the dustproof net 11 into the air intake port 22 at the bottom of the host housing 14, and blown toward the exhaust port 23, and finally blown out from the inside of the dust removal channel 12 at the bottom of the exhaust port 23 and the inside of the exhaust hole 10, forming a one-way air duct, with the help of which a continuous heat dissipation process is achieved. When the client 2 is not in use, the client 2 is reset by pulling the electric telescopic rod 37, so that the air intake port 22 and the exhaust port 23 at the bottom of the host housing 14 can be blocked simultaneously with the help of the interactive operating table 1 to achieve more efficient dustproof sealing processing.

[0056] In this embodiment, the guide mechanism 3 includes a base 24 and a column 26, the column 26 is welded to the top of the base 24, a support rod 27 is inserted at the top of the column 26, a lens module 28 is screwed in the middle of the support rod 27, and a through hole 25 is opened on the inner side of the base 24. A cleaning unit 30 is inserted into the through hole 25, and the cleaning unit 30 includes a translation rod 31 and a pressing plate 33, a bending rod 32 is integrally formed at the end of the translation rod 31, the pressing plate 33 is sleeved on the surface of the bending rod 32, a rubber pad 34 is attached to the bottom of the pressing plate 33, a spring 35 is sleeved on the surface of the translation rod 31, and a limiting convex plate 36 is welded to the other end of the translation rod 31.

[0057] Specifically, the lens module 28 can be used to identify whether there are students using the current client 2, and when no students are detected using it for a long time, the electric telescopic rod 37 can be automatically controlled to pull the client 2 to close. During the closing process, the main body shell 14 will move backward. At this time, due to the push of the spring 35, the pressing plate 33 and the rubber pad 34 at the end can be displaced from the surface of the first touch screen 16. The rubber pad 34 is used to scrape the surface of the first touch screen 16 in a moving state, so that the debris and dust that fall on the surface of the first touch screen 16 during use can be pushed out, and finally the scraped debris and dust are discharged with the help of the dust removal channel 12.

For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
