[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This information collection device uses a mechanical linkage mechanism triggered by pressing and releasing a foot pedal, which automatically opens and closes the baffle and wipes with disinfectant cotton. When the baffle is removed to expose the collection window, the disinfectant cotton simultaneously wipes the surface of the facial and fingerprint collectors, reducing the need for manual cleaning. When the baffle is reset, the cleaning is completed again and the collectors are protected from external contamination and accidental collisions. This automated design not only simplifies the operation process and improves information collection efficiency, but also extends the service life of the collection device through continuous cleaning, reducing maintenance costs.

[0016] 2. This information collection device uses the mechanical action of pressing and releasing the foot pedal to drive the air cylinder to complete the suction-exhaust cycle. High-speed airflow is ejected through the air outlet to remove dust and contaminants from the collector surface, ensuring accurate collection. Furthermore, the self-locking universal wheels installed at the bottom allow the device to be flexibly moved and fixed in any position, adapting to different usage scenarios. This design combines efficient cleaning with convenient mobility, enhancing the device's practicality and cleaning effectiveness. It is particularly suitable for information collection scenarios that require frequent movement and high cleanliness requirements.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0030] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the invention.

[0031] See also Figures 1-8 As shown, the present invention is an information collection device, including a fixed plate 1, a connecting plate 2 is fixedly installed above the fixed plate 1, a facial collector 3 and a fingerprint collector 4 are fixedly installed inside the connecting plate 2, the fixed plate 1 is slidably connected to a foot pedal 5, the foot pedal 5 is fixedly installed with a first rack 6, the first rack 6 is engaged with a first gear 7, the first gear 7 is fixedly installed on a first connecting shaft 8, one end of the first connecting shaft 8 is fixedly installed with a first bevel gear 9, the first bevel gear 9 is engaged with a second bevel gear 10, the second bevel gear 10 is fixedly installed with a first threaded rod 11, the first threaded rod 11 is threadedly connected to a baffle 12, and the baffle 12 is located at the front end of the facial collector 3 and the fingerprint collector 4.

[0032] The operating principle of the information collection device proposed in this invention is that when a user steps on a foot pedal 5, the pedal 5 slides along a fixed plate 1 and drives a first rack 6. The first rack 6 rotates a meshed first gear 7, which in turn rotates a first bevel gear 9 via a first connecting shaft 8. The first bevel gear 9 meshes with a second bevel gear 10, which in turn rotates a first threaded rod 11. The rotation of the first threaded rod 11 pushes a baffle 12, threadedly connected to it, to slide within the connecting plate 2, moving the baffle 12 away from the front ends of the facial collector 3 and fingerprint collector 4, thereby exposing the collection window for the user to collect information.

[0033] When the user releases the foot pedal 5, the return spring 15 pushes the foot pedal 5 back to its initial position, and the first rack 6 moves in the opposite direction, causing the first gear 7, the first connecting shaft 8, the first bevel gear 9, the second bevel gear 10 and the first threaded rod 11 to rotate in the opposite direction, and the baffle 12 then slides back to its original position, re-covering and protecting the facial collector 3 and the fingerprint collector 4.

[0034] It is worth noting that shorter students can use the fingerprint collector 4 to collect information, while taller students can choose freely.

[0035] In one embodiment, for the above-mentioned fixed plate 1, the fixed plate 1 is provided with a slot 13, the foot pedal 5 is slidably connected inside the slot 13, one end of the telescopic rod 14 is fixedly installed on the foot pedal 5, the other end of the telescopic rod 14 is fixedly installed on the bottom of the slot 13, and the telescopic rod 14 is provided with a return spring 15.

[0036] In one embodiment, for the above-mentioned first connecting shaft 8, the first connecting shaft 8 is rotatably installed inside the fixed plate 1, the first threaded rod 11 is rotatably installed inside the connecting plate 2, the baffle 12 is slidably connected inside the connecting plate 2, and a side of the baffle 12 close to the facial collector 3 and the fingerprint collector 4 is provided with disinfectant cotton.

[0037] The operating principle of the information collection device proposed in the present invention is that when a user steps on a foot pedal 5, the foot pedal 5 slides within a slot 13 of a fixed plate 1, simultaneously compressing a telescopic rod 14 and a return spring 15. The movement of the foot pedal 5 causes the first rack 6 to move linearly, which in turn drives the first gear 7 to rotate. The first gear 7 rotates the first bevel gear 9 via a first connecting shaft 8. The first bevel gear 9 meshes with the second bevel gear 10, causing the second bevel gear 10 to rotate. The second bevel gear 10 drives the first threaded rod 11 to rotate within the connecting plate 2. The rotational motion of the first threaded rod 11 is converted into linear motion of the baffle 12, causing it to slide along the connecting plate 2, thereby exposing the facial collector 3 and fingerprint collector 4.

[0038] During this process, the disinfection cotton inside the baffle 12 always keeps in contact with the surface of the facial collector 3 and the fingerprint collector 4, and automatically wipes and cleans the collector surface when the baffle 12 moves.

[0039] When the user releases the foot pedal 5, the return spring 15 pushes the telescopic rod 14 to extend, causing the foot pedal 5 to return to its original position. The foot pedal 5 moves in the opposite direction, causing the first rack 6 to drive the first gear 7 in reverse. This, in turn, through the linkage of the first connecting shaft 8, the first bevel gear 9, the second bevel gear 10, and the first threaded rod 11, causes the baffle 12 to slide back to its original position, re-covering and protecting the facial collector 3 and fingerprint collector 4, while the disinfectant cotton completes the wiping action again.

[0040] In one embodiment, for the above-mentioned foot pedal 5, a second rack 17 is fixedly installed at the bottom of the foot pedal 5, the second rack 17 is engaged with a second gear 18, the second gear 18 is fixedly installed with a threaded barrel 19, the internal thread of the threaded barrel 19 is connected to a second threaded rod 20, the second gear 18 is fixedly installed on a second connecting shaft 23, and the second connecting shaft 23 is rotatably installed inside the fixed plate 1.

[0041] In one embodiment, for the above-mentioned second threaded rod 20, the second threaded rod 20 is fixedly installed with a piston 21, the piston 21 is slidably connected to the inside of the gas cylinder 22, the gas cylinder 22 is fixedly installed inside the fixed plate 1, and the gas cylinder 22 is fixedly connected to one end of the gas pipe 24, and the other end of the gas pipe 24 passes through the fixed plate 1 and is fixedly connected to the diverter plate 25.

[0042] In one embodiment, the diverter plate 25 is fixedly installed above the fixed plate 1 , and the diverter plate 25 is fixedly connected to an air jet 26 , and a plurality of air jets 26 are provided.

[0043] The operating principle of the information collection device proposed in this invention is that when a user steps on foot pedal 5, it drives second rack 17 downward. Second rack 17 drives second gear 18 to rotate clockwise, which in turn drives threaded barrel 19 via second connecting shaft 23. The rotation of threaded barrel 19 causes second threaded rod 20 to extend outward, pulling piston 21 within cylinder 22 toward connecting plate 2. At this point, cylinder 22 draws in external air through air pipe 24 and air outlet 26 of manifold 25, creating an inhalation process.

[0044] When the user releases foot pedal 5, return spring 15 pushes foot pedal 5 back upward, driving second rack 17 upward. Second rack 17 drives second gear 18 to rotate counterclockwise, causing threaded cylinder 19 to retract second threaded rod 20 inward, pushing piston 21 within cylinder 22 away from connecting plate 2. Piston 21 compresses the air within cylinder 22, which is then transported via air pipe 24 to manifold 25 and ejected at high speed from multiple jet ports 26, completing the jet cleaning process.

[0045] During this process, the system inhales air to store energy when pedal 5 is depressed, and releases the air to clean the air. This reciprocating pedaling action creates an automated inhalation-exhalation cycle. The high-speed airflow from air jets 26 effectively removes dust and contaminants from the surfaces of facial and fingerprint sensors 3 and 4.

[0046] In one embodiment, for the above-mentioned fixed plate 1 , a universal wheel 27 is fixedly installed on the bottom of the fixed plate 1 . There are a plurality of universal wheels 27 , and all of the universal wheels 27 are self-locking.

[0047] In one embodiment, for the above-mentioned connecting plate 2 , a monitoring camera 28 is fixedly installed on the connecting plate 2 , and the disinfection cotton is attached to the facial collector 3 and the fingerprint collector 4 .

[0048] The working principle of the information collection device proposed by the present invention is that the device can be moved at will through the universal wheels 27 and can also be fixed through the self-locking property.
