The inclusion of a magnetic card sensor window (6) and an ID card sensor window (12) significantly expands the depth and breadth of human-computer interaction. These two sensors offer users diverse authentication methods; whether swiping a card or ID card, the system can quickly and accurately identify user identity information. Based on this, the system can tailor personalized services for different users, including access control, convenient user registration and login, and exclusive services to meet specific needs. This intelligent identity authentication and personalized service mechanism not only enhances the security of interaction but also allows each user to... Experiencing personalized care and meeting the complex and ever-changing interactive needs in different scenarios, the Q&A interactive speaker 7 adds a vivid voice element to the entire interaction process. With clear sound quality and moderate volume, it accurately conveys the system-generated voice content to the user. Through close cooperation with the Q&A display screen 9, it realizes voice interaction functionality, allowing users to obtain information more naturally and conveniently during operation, without constantly focusing on the screen. Especially in certain scenarios, such as when the user's hands are busy or their vision is impaired, the advantages of voice interaction are fully demonstrated.

[0030] like Figure 1 , Figure 7 and Figure 8 As shown, the top and left and right outer walls of the display stand 8 are connected to a retractable and adjustable privacy protection device 24. The retractable and adjustable privacy protection device 24 includes a U-shaped fixed back plate 28, a U-shaped sliding frame 29, an operating handle 30, and a U-shaped retractable corrugated cover 31. The left and right outer walls and the top of the back of the display stand 8 are connected to the U-shaped fixed back plate 28. The U-shaped retractable corrugated cover 31 is attached to the front outer wall of the U-shaped fixed back plate 28. The front end of the U-shaped retractable corrugated cover 31 is connected to the U-shaped sliding frame 29. The left and right ends of the U-shaped sliding frame 29 are provided with operating handles 30. The operating handles 30 can drive the U-shaped sliding frame 29 to move back and forth. Moving the U-shaped sliding frame 29 forward can stretch the U-shaped retractable corrugated cover 31. Moving the U-shaped sliding frame 29 backward can compress the U-shaped retractable corrugated cover 31. The cover 31 is a key component for achieving privacy protection and light blocking functions. Its front end is connected to the U-shaped sliding frame 29, and its rear end is glued and fixed to the front outer wall of the U-shaped fixed back plate 28. This connection method allows the U-shaped retractable corrugated cover 31 to be stretched and compressed under the action of the U-shaped sliding frame 29. When privacy protection or light blocking is required for the question-and-answer all-in-one machine, push the operating handle 30 forward, and the U-shaped sliding frame 29 moves forward along the track rod 26, stretching the U-shaped retractable corrugated cover 31. As the U-shaped sliding frame 29 moves forward, the U-shaped retractable corrugated cover 31 gradually unfolds, eventually completely covering the front left and right sides and the upper outer side of the display base 8, forming a protective barrier. This effectively prevents others from peeping at the screen content and blocks direct light from shining on the question-and-answer display screen 9 in strong light environments, avoiding reflections that affect the viewing effect.

[0031] like Figure 1 , Figure 7 and Figure 8As shown, the retractable and adjustable privacy protection device 24 also includes an anti-detachment baffle 25, a track rod 26, and a metal sliding sleeve 27.

The two metal sliding sleeves 27 are respectively fitted onto the outside of the two track rods 26, allowing them to move back and forth outside the track rods 26. To ensure that the U-shaped sliding frame 29 slides smoothly on the track and does not derail, an anti-detachment baffle 25 is provided at the front end of the track rod 26. Metal sleeves 27 welded on the left and right sides of the center are respectively fitted onto the outside of the two track rods 26. The cooperation between the metal sleeves 27 and the track rods 26 not only provides guidance for the back and forth movement of the U-shaped sliding frame 29, but also limits the travel range of the U-shaped sliding frame 29 through the anti-detachment baffle 25, ensuring its stable operation under normal working conditions. When the privacy protection function is not needed, pull the operating handle 30 backward, and the U-shaped sliding frame 29 moves backward along the track rod 26. The U-shaped retractable corrugated cover 31 is compressed accordingly. The retractable feature of the U-shaped retractable corrugated cover 31 allows it to be stored without taking up too much space, ensuring the simplicity and compactness of the overall appearance of the all-in-one machine.

[0032] like Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, safety operating devices 4 are connected to the outer walls of the left and right ends of the operating platform 5. The safety operating devices 4 include a fixed plate 14, a U-shaped groove 16, a horizontal guide roller A17, and a horizontal guide roller B22. Two fixed plates 14 are provided, symmetrically fixed to the outer walls of the left and right ends of the operating platform 5. Each fixed plate 14 has a downward-recessed U-shaped groove 16 at its top, with the U-shaped openings of both grooves facing upwards. Horizontal guide rollers A17 and B22 are respectively connected to the interior of each U-shaped groove 16 via roller shafts. Guide rollers B22 are located on the right and left sides of the operating table 5, respectively. The tops of both horizontal guide rollers A17 and B22 extend above the top outer wall of the operating table 5. Both horizontal guide rollers A17 and B22 can rotate clockwise and counterclockwise within the U-shaped groove 16 via roller shafts. The function of horizontal guide rollers A17 and B22 is to guide the movement path of the transparent film 18, ensuring that the film can stably cover the operating table 5. The safety operating device 4 also includes an unwinding shaft 15, a U-shaped unwinding frame 19, a winding knob 20, a winding shaft 21, and a U-shaped winding frame 23, and two fixing plates 14. A U-shaped unwinding frame 19 and a U-shaped winding frame 23 are fixed to the outer wall respectively. The U-shaped winding frame 23 and the U-shaped unwinding frame 19 are arranged symmetrically from left to right. The U-shaped opening of the U-shaped unwinding frame 19 faces to the right, and the U-shaped opening of the U-shaped winding frame 23 faces to the left. An unwinding shaft 15 is installed inside the U-shaped unwinding frame 19, and a winding shaft 21 is installed inside the U-shaped winding frame 23. A winding knob 20 is installed at the front end of the winding shaft 21. The winding knob 20 is located on the front side of the outer wall of the front end of the U-shaped winding frame 23. The safety operation device 4 also includes a transparent film 18. The shaft of the unwinding shaft 15 is wrapped with layers of transparent film 18, and the transparent film 18... Located inside the U-shape of the U-shaped unwinding frame 19, the unwinding shaft 15 can rotate clockwise and counterclockwise within the U-shaped unwinding frame 19, and the winding knob 20 can drive the winding shaft 21 to rotate clockwise and counterclockwise. Before the device is used, the transparent film 18 is neatly stored inside the U-shaped unwinding frame 19. When the safety operation device 4 needs to be used, the unwinding shaft 15 can rotate clockwise and counterclockwise within the U-shaped unwinding frame 19 to release the transparent film 18. At the same time, the winding shaft 21 inside the U-shaped winding frame 23 is equipped with a winding knob 20 at its front end. The winding knob 20 drives the winding shaft 21 to rotate clockwise and counterclockwise, which is responsible for recycling the used transparent film 18.

[0033] like Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, after the outermost end of the transparent film 18 wrapped around the outside of the unwinding shaft 15 is removed, the transparent film 18 can be sequentially moved from right to left into the top of the horizontal guide rollers A17 and B22. The outermost end of the removed transparent film 18 can finally be wrapped around the outside of the take-up shaft 21, and the removed transparent film 18 can completely cover the top of the operating table 5. During the counterclockwise rotation of the take-up shaft 21, the transparent film 18 is pulled to the left. The tension can simultaneously cause the unwinding shaft 15 to rotate counterclockwise and release the layers of transparent film 18 wrapped around the outside of the unwinding shaft 15. In this process, the transparent film 18 is gradually flattened and completely covers the top of the operating table 5, forming an isolation layer that directly separates the user from the operating table 5. When the take-up shaft 21 rotates counterclockwise, it pulls the transparent film 18 to the left. 8. This pulling force synchronously causes the unwinding shaft 15 to rotate counterclockwise, thereby continuously releasing the transparent film 18 wound around the outside of the unwinding shaft 15. In this way, with the operation of different users, the take-up shaft 21 continuously pulls the used film, and the unwinding shaft 15 continuously replenishes new film, realizing the cyclical movement and use of the transparent film 18. Through the coordinated operation of the above components, each new user comes into contact with a brand new transparent film 18 surface when operating. During the process of different users taking turns using the operating table 5, the contaminated film portion is continuously recovered by the take-up shaft 21, and the new film portion is continuously released from the unwinding shaft 15 and covers the operating table 5.
