Description

Technical Field

[0001] This invention relates to the field of health monitoring equipment technology, specifically to a tongue image acquisition device with disinfection function. Background Technology

[0002] Generally speaking, a tongue image acquisition device is a collection and analysis device used for tongue diagnosis and health status identification in traditional Chinese medicine. During the tongue image acquisition process, the user needs to open their mouth and stick out their tongue so that the tongue surface is fully exposed to the shooting area in order to complete a clear image.

[0003] In the process of tongue image acquisition, oral exposure and close-range acquisition are key steps, and their hygiene directly affects the health and safety of users and the reliability of equipment use. However, in actual operation, when users open their mouths, exhale, and speak, they generate a large number of droplets, water vapor, and aerosols. These contaminants can adhere to the internal cavity walls, lenses, and supplementary lighting components of the equipment, forming bacterial and viral residues. Due to the complex internal structure of the equipment and the presence of many dead corners, conventional cleaning methods are difficult to cover all contaminated areas, which can easily lead to incomplete disinfection and the presence of pathogenic microorganisms in some areas. If the next user continues to use the equipment, the residual contaminants can cause cross-infection through air contact and droplet transmission, posing health and safety risks. At the same time, traditional equipment does not have fully automatic and full-coverage internal disinfection capabilities and relies on manual wiping disinfection, which is not only cumbersome and inefficient but also makes it difficult to guarantee the consistency and thoroughness of disinfection. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a tongue image acquisition device with disinfection function, thereby solving the technical problems in the prior art.

[0005] The objective of this invention can be achieved through the following technical solutions: A tongue image acquisition device with disinfection function, comprising: A base is provided, on which a spherical shell is fixedly installed. Inside the spherical shell, a camera, a fill light, and a spray nozzle are fixedly installed. A perforated end cap is fixedly installed at the open end of the spherical shell. An external gear ring is rotatably installed on the side of the perforated end cap facing the spherical shell. A drive assembly is provided on the perforated end cap. The external gear ring is driven to rotate by the drive assembly. A mounting seat is fixedly installed on the side of the external gear ring facing the spherical shell. A horizontal plate is provided on the mounting seat. The horizontal plate extends into the spherical shell and is horizontally arranged. A groove is provided at the end of the horizontal plate away from the mounting seat. A tripod is fixedly installed on a horizontal plate. Multiple first ultraviolet lamps are fixedly installed at equal intervals on the top of the two waist sides of the tripod. The first ultraviolet lamps face the inner arc surface of the inner wall of the spherical shell. The rotating frame is rotatably installed in the groove. The rotating frame is driven to rotate by a first motor fixedly installed on the horizontal plate. Multiple second ultraviolet lamps are fixedly installed on the rotating frame at equal intervals. When the first motor drives the rotating frame to rotate to a vertical position, the second ultraviolet lamps face the side of the inner wall of the spherical shell where the camera, cleaning rod and spray nozzle are fixedly installed.

[0006] As a further aspect of the present invention: a plurality of louvers are rotatably mounted in the middle of the tripod, each of the louvers being coaxially and fixedly connected to a rotating shaft. The rotating shaft is rotatably mounted on the bottom edge of the tripod and extends into the groove. Every two adjacent rotating shafts are connected by a first synchronous belt. A linkage assembly is provided on the horizontal plate, and the rotating frame is connected to the linkage assembly. The rotating frame drives a rotating shaft to rotate through the linkage assembly. When the first motor drives the rotating frame to unfold, the rotating frame drives the rotating shaft to rotate through the linkage assembly, causing the louvers to open. At this time, there is a gap between two adjacent louvers. When the first motor drives the rotating frame to retract into the groove, the rotating frame drives the rotating shaft to rotate through the linkage assembly, causing the louvers to close. At this time, two adjacent louvers are closed.

[0007] As a further embodiment of the present invention: the linkage component includes a fixed box, a first bevel gear, a second bevel gear, and a transmission component. The fixed box is fixedly installed in the groove. When the rotating frame retracts into the groove, the rotating frame moves away from the fixed box. The first bevel gear and the second bevel gear are both rotatably installed in the fixed box. The first bevel gear and the second bevel gear mesh, and their axes are perpendicular to each other. A rotating shaft passes through the fixed box and is coaxially and fixedly connected to the second bevel gear. The transmission component is disposed on the horizontal plate, and the rotating frame is connected to the first bevel gear through the transmission component.

[0008] As a further embodiment of the present invention: the transmission assembly includes a driving rod, a driven rod, and a second synchronous belt. The driving rod and the driven rod are both rotatably mounted on one side of the horizontal plate. The driving rod is connected to the driven rod via the second synchronous belt. The driving rod is coaxially and fixedly connected to the rotating frame. The driven rod is coaxially and fixedly connected to the first bevel gear.

[0009] As a further embodiment of the present invention: the driving assembly includes a transmission gear and a second motor. The transmission gear is rotatably mounted on the end cover with holes and meshes with an external gear ring. The second motor is fixedly mounted on the end cover with holes, and the transmission gear is driven to rotate by the second motor.

[0010] As a further aspect of the present invention: a protective sheet is fixedly installed on the camera, and a cleaning rod is rotatably installed inside the spherical shell. The cleaning rod is driven to rotate by a drive source, and the cleaning rod is slidably engaged with the protective sheet.

[0011] As a further aspect of the present invention: a support plate is fixedly installed on the side of the perforated end cap away from the spherical shell, and a chamfer is provided at the opening of the perforated end cap.

[0012] As a further aspect of the present invention: the horizontal plate and the mounting base are detachably connected, the horizontal plate is connected to the mounting base by a screw, and the screw is threadedly connected to the mounting base.

[0013] The beneficial effects of this invention are: 1. In this invention, by setting a horizontal plate that can revolve within the spherical shell cavity and a retractable rotating frame, combined with a first ultraviolet lamp on the tripod and a second ultraviolet lamp on the rotating frame, a full-area ultraviolet irradiation structure is formed. The first ultraviolet lamp is close to the arc-shaped inner wall of the spherical shell, and the second ultraviolet lamp can be unfolded and aligned with the vertical mounting surface. With the help of the external gear ring driving the horizontal plate to revolve, the arc-shaped inner wall and the vertical mounting surface are covered without dead angles. Then, disinfectant alcohol is sprayed from the spray nozzle for secondary disinfection. This structure can specifically solve the problems of limited disinfection range and inability to cover gaps and dead angles in the cavity of traditional tongue tapping devices. Through dry and mist dual disinfection, droplets and aerosol residues are thoroughly removed, eliminating the risk of cross-infection. 2. In this invention, a louvered blade with a changeable shape is added in the middle of the tripod. The louvered blade is fixed coaxially with the rotating shaft and connected to the rotating frame through a linkage component. It can open and close synchronously with the expansion and contraction of the rotating frame. The shape changes automatically when switching between disinfection stages. When the dry ultraviolet sterilization is performed, the louvered blade opens to ensure smooth airflow and avoid disturbing pollutants. When the spray disinfection is performed, the louvered blade closes to form a fan-shaped structure. The air in the inner cavity is disturbed by the revolution of the horizontal plate to form a vortex, which allows the disinfectant alcohol to quickly diffuse to the entire area, effectively improving the uniformity and thoroughness of spray disinfection and solving the problem of dead corners that are easy to occur in traditional fixed sprays. 3. In this invention, a protective sheet is fixedly installed on the surface of the camera, which can directly isolate the camera from the corrosion of disinfectant mist, alcohol and pollutants. At the same time, a rotatable cleaning rod is set inside the spherical shell. After spray disinfection, the cleaning rod is driven by the drive source to slide and cooperate with the protective sheet, automatically scraping off the alcohol droplets and stains condensed on the surface of the protective sheet, avoiding water stains from affecting the clarity of the image. This not only effectively protects the camera and extends its service life, but also ensures the stability and clarity of tongue image acquisition, solving the problems of traditional tongue-capturing devices where the camera is easily contaminated and the shooting effect is poor.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-9 As shown, the present invention is a tongue image acquisition device with disinfection function, comprising: A base 1 is provided, on which a spherical shell 2 is fixedly installed. A camera 4, a fill light 7, and a spray nozzle 8 are fixedly installed inside the spherical shell 2. A perforated end cap 3 is fixedly installed at the open end of the spherical shell 2. An external gear ring 9 is rotatably installed on the side of the perforated end cap 3 facing the spherical shell 2. A driving component is provided on the perforated end cap 3. The external gear ring 9 is driven to rotate by the driving component. A mounting base 10 is fixedly installed on the side of the external gear ring 9 facing the spherical shell 2. A horizontal plate 11 is provided on the mounting base 10. The horizontal plate 11 extends into the spherical shell 2 and is horizontally arranged. A groove 17 is provided at the end of the horizontal plate 11 away from the mounting base 10. Tripod 12 is fixedly installed on horizontal plate 11. Multiple first ultraviolet lamps 13 are fixedly installed at equal intervals on the top of the two waist sides of the tripod 12. The first ultraviolet lamps 13 face the inner arc surface of the inner wall of the spherical shell 2. The rotating frame 14 is rotatably installed in the groove 17. The rotating frame 14 is driven to rotate by the first motor 18 fixedly installed on the horizontal plate 11. Multiple second ultraviolet lamps 15 are fixedly installed on the rotating frame 14 at equal intervals. When the first motor 18 drives the rotating frame 14 to rotate to a vertical state, the second ultraviolet lamps 15 face the side of the inner wall of the spherical shell 2 where the camera 4, cleaning rod 6 and spray nozzle 8 are fixedly installed.

[0019] The working principle of this invention: The user aligns their face with the opening of the perforated end cap 3 and places it against the opening, opens their mouth and sticks out their tongue. The supplementary light 7 is turned on to provide supplementary light, and the camera 4 takes a clear picture of the tongue. After a single shot, to avoid cross-infection caused by droplets and aerosol residue, the inside of the spherical shell 2 needs to be automatically disinfected: First, it enters the dry ultraviolet sterilization stage. The first ultraviolet light 13 and the second ultraviolet light 15 are turned on simultaneously to irradiate the entire inner wall of the spherical shell 2. The internal cavity of the spherical shell 2 is divided into an arc-shaped inner wall and a vertical mounting surface. The first motor 18 drives the rotating frame 14 to unfold from the groove 17, so that the second ultraviolet light 15 is facing the vertical area where the camera 4 and the supplementary light 7 are located. The tripod 12 keeps the first ultraviolet light 13 close to the arc-shaped inner wall of the spherical shell 2 to ensure the intensity and uniformity of ultraviolet irradiation. The drive component drives the outer gear ring 9 to rotate, which in turn drives the horizontal plate 11 along the spherical shell 2 through the mounting base 10. The inner cavity revolves once, allowing the first ultraviolet lamp 13 to completely sweep across the arc-shaped inner wall and the second ultraviolet lamp 15 to completely cover the vertical mounting surface, achieving dry sterilization of the entire cavity without dead angles. After dry sterilization is completed, the first motor 18 drives the rotating frame 14 to retract into the groove 17, protecting the second ultraviolet lamp 15. Then, the spray disinfection stage begins, where disinfectant alcohol is sprayed from the spray nozzle 8, creating an atomized disinfection environment in the cavity. This provides secondary disinfection for gaps and dead angles that are difficult for ultraviolet light to completely cover, thus achieving a thorough, safe, and fully automatic disinfection process inside the spherical shell 2.

[0020] like Figures 1-6As shown, in a preferred embodiment of the present invention, a plurality of louvers 16 are rotatably mounted in the middle of the tripod 12. Each louver 16 is coaxially fixedly connected to a rotating shaft 1601. The rotating shaft 1601 is rotatably mounted on the bottom edge of the tripod 12 and extends into the groove 17. Every two adjacent rotating shafts 1601 are connected by a first synchronous belt 19. A linkage assembly is provided on the horizontal plate 11. The rotating frame 14 is connected to the linkage assembly. The rotating frame 14 drives a rotating shaft 1601 to rotate through the linkage assembly. When the first motor 18 drives the rotating frame 14 to unfold, the rotating frame 14 drives the rotating shaft 1601 to rotate through the linkage assembly, causing the louvers 16 to open. At this time, there is a gap between two adjacent louvers 16. When the first motor 18 drives the rotating frame 14 to retract into the groove 17, the rotating frame 14 drives the rotating shaft 1601 to rotate through the linkage assembly, causing the louvers 16 to close. At this time, two adjacent louvers 16 are closed.

[0021] In practical application, during the dry ultraviolet sterilization stage, the outer gear ring 9 drives the horizontal plate 11 to slowly rotate. At this time, the louvers 16 are in the open state, and the airflow inside the spherical shell 2 can smoothly pass through the gaps between the louvers 16, avoiding strong airflow disturbance and floating pollutants. This allows the first ultraviolet lamp 13 and the second ultraviolet lamp 15 to stably irradiate each wall surface of the cavity, improving sterilization efficiency and uniformity. After the dry sterilization is completed, the spray disinfection stage begins. The second ultraviolet lamp 15 is turned off, the rotating frame 14 retracts into the groove 17, and the linkage component drives the louvers 16 to close. Multiple louvers 16 are combined to form a fan-shaped structure. When the horizontal plate 11 continues to rotate, the closed louvers 16 can violently disturb the air inside the spherical shell 2, forming a vortex airflow. This allows the disinfectant alcohol sprayed from the spray nozzle 8 to quickly diffuse throughout the cavity, greatly improving the coverage and uniformity of atomized disinfection and solving the problem of dead corners and incomplete disinfection that are common with traditional fixed sprays.

[0022] like Figures 1-8 As shown, in a preferred embodiment of the present invention, the linkage assembly includes a fixed box 20, a first bevel gear 22, a second bevel gear 23, and a transmission assembly. The fixed box 20 is fixedly installed in the groove 17. When the rotating frame 14 retracts into the groove 17, the rotating frame 14 moves away from the fixed box 20. The first bevel gear 22 and the second bevel gear 23 are both rotatably installed in the fixed box 20. The first bevel gear 22 and the second bevel gear 23 mesh, and their axes are perpendicular to each other. A rotating shaft 1601 passes through the fixed box 20 and is coaxially fixedly connected to the second bevel gear 23. The transmission assembly is disposed on the horizontal plate 11, and the rotating frame 14 is connected to the first bevel gear 22 through the transmission assembly.

[0023] Specifically, the transmission assembly includes a driving rod 1401, a driven rod 2201, and a second synchronous belt 21. Both the driving rod 1401 and the driven rod 2201 are rotatably mounted on one side of the horizontal plate 11. The driving rod 1401 is connected to the driven rod 2201 via the second synchronous belt 21. The driving rod 1401 is coaxially fixedly connected to the rotating frame 14, and the driven rod 2201 is coaxially fixedly connected to the first bevel gear 22.

[0024] In practical application, when the equipment enters the dry ultraviolet sterilization stage, the first motor 18 starts and drives the rotating frame 14 to rotate from the groove 17 outward to a vertical position. Since the driving rod 1401 is coaxially fixed with the rotating frame 14, the rotation of the rotating frame 14 will synchronously drive the driving rod 1401 to rotate. The driving rod 1401 transmits power to the driven rod 2201 through the second synchronous belt 21, causing the driven rod 2201 to rotate synchronously with the driving rod 1401. The driven rod 2201 is coaxially fixed with the first bevel gear 22, thereby driving the first bevel gear 22 to rotate. The bevel gear 22 and the second bevel gear 23 mesh with each other and their axes are perpendicular. The rotational motion of the first bevel gear 22 can be converted into the vertical rotation of the second bevel gear 23. The second bevel gear 23 is coaxially fixed with one of the rotating shafts 1601, so it will drive the rotating shaft 1601 to rotate synchronously. Since two adjacent rotating shafts 1601 are connected by the first synchronous belt 19, the rotation of a single rotating shaft 1601 will drive all rotating shafts 1601 to rotate synchronously through the first synchronous belt 19, ultimately realizing the synchronous opening of all louvers 16, which meets the requirement of stable airflow during the dry sterilization stage. When dry sterilization is complete and the spray disinfection stage begins, the first motor 18 starts in reverse, driving the rotating frame 14 to retract into the groove 17. At this time, the rotating frame 14 drives the active rod 1401 to rotate in the opposite direction. The power is transmitted sequentially through the second synchronous belt 21, the driven rod 2201, the first bevel gear 22, and the second bevel gear 23, driving all rotating shafts 1601 to rotate in the opposite direction, causing the louvers 16 to close synchronously, forming a fan-shaped structure, which provides the basis for the subsequent formation of vortex airflow. The entire linkage process is smooth and responsive. Through the rotation conversion of the bevel gears and the power transmission of the synchronous belt, it is ensured that the opening and retraction of the rotating frame 14 can accurately correspond to the opening and closing of the louvers 16, without manual intervention. This perfectly matches the overall design requirements of the fully automatic disinfection equipment. At the same time, the fixing box 20 can seal and protect the first bevel gear 22 and the second bevel gear 23, preventing corrosion caused by the contact of disinfectant alcohol atomization with the gear structure, and extending the service life of the linkage components.

[0025] like Figures 1-8As shown, in a preferred embodiment of the present invention, the drive assembly includes a transmission gear 26 and a second motor 27. The transmission gear 26 is rotatably mounted on the perforated end cover 3 and meshes with the external gear ring 9. The second motor 27 is fixedly mounted on the perforated end cover 3, and the transmission gear 26 is driven to rotate by the second motor 27.

[0026] In practical application, the second motor 27 drives the transmission gear 26 to rotate, and the transmission gear 26 drives the outer gear ring 9 to revolve around the end cover 3 with holes. The outer gear ring 9 drives the horizontal plate 11, the tripod 12 and the rotating frame 14 to move around the inner cavity of the spherical shell 2 through the mounting base 10, so that the first ultraviolet lamp 13 continuously sweeps along the arc-shaped inner wall to achieve full-area ultraviolet irradiation, solving the problem of limited irradiation range and blind spots of traditional fixed ultraviolet lamps.

[0027] like Figures 1-4 As shown, in a preferred embodiment of the present invention, a protective sheet 5 is fixedly installed on the camera 4, and a cleaning rod 6 is rotatably installed inside the spherical shell 2. The cleaning rod 6 is driven to rotate by a drive source, and the cleaning rod 6 is slidably engaged with the protective sheet 5.

[0028] In one embodiment, the driving source may be a servo motor, a servo motor or other components, or other mechanisms capable of rotational motion. This embodiment does not impose specific limitations on these components.

[0029] In practical application, during the disinfection process of the spray nozzle 8, alcohol droplets easily condense into water droplets on the surface of the protective sheet 5. After drying, these droplets can easily form water stains, affecting the clarity of the image. By driving the cleaning rod 6 to rotate, the surface of the protective sheet 5 can be automatically scraped to remove water, preventing water stains and dirt residue from remaining. This ensures that the image captured by the camera 4 is always clear and stable. At the same time, the protective sheet 5 can prevent the camera 4 from being directly corroded by fog and alcohol, extending the service life of the camera module.

[0030] like Figures 1-9 As shown, in a preferred embodiment of the present invention, a support plate 25 is fixedly installed on the side of the perforated end cap 3 away from the spherical shell 2, and a chamfer is provided at the opening of the perforated end cap 3.

[0031] In practical applications, the support plate 25 can support the user's chin, allowing the face to fit stably against the perforated end cap 3, ensuring a uniform tongue image capture position and clear images. The chamfered opening can prevent sharp edges from causing facial pressure or scratches, improving user comfort and safety.

[0032] like Figures 1-6As shown, in a preferred embodiment of the present invention, the horizontal plate 11 and the mounting base 10 are detachably connected, and the horizontal plate 11 is connected to the mounting base 10 by a screw 24, which is threadedly connected to the mounting base 10.

[0033] In practical application, after the rotating frame 14 retracts into the groove 17, the screw 24 can be removed to take out the horizontal plate 11, the tripod 12, the first ultraviolet lamp 13, the second ultraviolet lamp 15 and other components from the spherical shell 2 as a whole, which facilitates later maintenance, repair and replacement, and reduces the difficulty and cost of equipment maintenance.

[0034] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
