[0017] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0018] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0019] Please see Figures 1-14 This application provides a tongue and facial examination and skin testing instrument fixing device 100, including: a main body 10, a camera 20, a chin fixing mechanism 40, and a forehead fixing mechanism 30. The main body 10 has a camera cavity 11 for placing a human head. The camera 20 is fixedly connected to the camera cavity 11. The forehead fixing mechanism 30 is connected to the main body 10, located within the camera cavity 11, and is slidably connected to the human forehead. The chin fixing mechanism 40 is connected to the main body 10, located within the camera cavity 11, and is slidably connected to the human chin. When the human face rotates relative to the camera 20, the forehead fixing mechanism 30 and the chin fixing mechanism 40 slide against the human body, and the camera 20 captures images of the front and side views of the human face.

[0020] Specifically, the main body 10 serves as the supporting structure for the entire device. Its design is robust and stable, ensuring it will not shake due to external factors (such as vibration or impact) during the testing process. The imaging cavity 11 on the main body 10 is carefully designed in shape and size to comfortably accommodate the human head while ensuring sufficient space during shooting to prevent pressure on the head. This ensures the airtightness of the shooting space.

[0021] The camera module 20 is one of the core components of the detection device. It is fixedly connected to the camera cavity 11 and is responsible for capturing high-definition images of the face. The camera module 20 may employ advanced camera technology, featuring high resolution and high sensitivity, ensuring that the captured images are clear and accurate. In addition, the position and angle of the camera module 20 are precisely calibrated to ensure that every detail of the face, including the tongue and skin texture, can be captured.

[0022] The forehead fixation mechanism 30 is connected to the main body 10 and located within the imaging cavity 11. It fits snugly against the forehead and is fixed in place by a sliding connection. This design not only effectively prevents the head from shaking during the inspection process but also allows for fine-tuning according to the individual's head shape, improving the fixation effect and imaging accuracy.

[0023] The chin fixing mechanism 40 is also connected to the main body 10 via a sliding connection, located inside the camera cavity 11, and fits snugly against the human chin. This design not only helps stabilize the head but also ensures that the chin position is fixed during shooting, thereby capturing a clearer profile image.

[0024] The forehead fixing mechanism 30 and the chin fixing mechanism 40 are located above and below the camera cavity 11, respectively, forming a front and rear clamping effect on the head. This design not only helps stabilize the head but also maintains the head's natural posture during shooting, avoiding facial distortion or shooting angle deviation caused by improper fixing.

[0025] The fixation device achieves stable fixation and flexible adjustment of the head through a sliding connection design between the forehead fixation mechanism 30 and the chin fixation mechanism 40. Meanwhile, the high-definition imaging capability of the camera 20 ensures clear and accurate images. This design not only improves the efficiency and accuracy of tongue diagnosis and skin examination but also reduces the misdiagnosis rate caused by improper fixation.

[0026] Furthermore, the forehead fixing mechanism 30 and the chin fixing mechanism 40 slide in the direction of neck rotation when the human neck rotates until they come into contact with the positioning groove. At this point, the shooting angle is fixed, ensuring the comprehensiveness of the shooting angle.

[0027] In one specific embodiment, the fixing device includes a first slide rail 50 and a second slide rail 60. One end of the first slide rail 50 is connected to the body 10, and the other end of the first slide rail 50 is slidably connected to the forehead fixing mechanism 30. The first slide rail 50 is located at the end opposite to the camera cavity 11. One end of the second slide rail 60 is connected to the body 10, and the other end of the second slide rail 60 is slidably connected to the chin fixing mechanism 40. The second slide rail 60 is disposed opposite to the first slide rail 50.

[0028] Specifically, one end of the first slide rail 50 is connected to the main body (body 10) of the fixing device, while the other end is slidably connected to the forehead fixing mechanism 30. This allows the forehead fixing mechanism 30 to move along the first slide rail 50 to accommodate different shooting angles of the user's face.

[0029] The first slide rail 50 is located at the end opposite to the imaging cavity 11, meaning it is situated on one side of the detector body, away from the imaging area used to photograph the tongue or skin. This helps ensure that the forehead fixation mechanism 30 does not interfere with the imaging process during adjustment.

[0030] Second slider 60: Similar to the first slider 50, it is used to adapt to different shooting angles of different areas of the user's face.

[0031] The second slide rail 60 is positioned opposite the first slide rail 50, meaning they are located on opposite sides of the detector body and are typically parallel or nearly parallel. This arrangement helps ensure that the forehead and chin fixation mechanisms 40 can be adjusted simultaneously and harmoniously to accommodate the facial features of different users.

[0032] In one specific embodiment, both the first slide rail 50 and the second slide rail 60 are arc-shaped, and the protrusions of the arc shape are located at the end furthest from the human body. The arc shape of both the first and second slide rails 60 conforms to the natural curve of the human neck, helping to reduce friction and discomfort when adjusting the forehead and chin fixation mechanism 40.

[0033] Specifically, the location of the raised dot: the arc-shaped raised dot is located at the end furthest from the body, meaning that the curved part of the slide rail faces outwards from the main body of the detector, while the inner side is closer to the user's neck. This design allows the slide rail to move along the natural curve of the user's neck during adjustment, reducing pressure on the neck.

[0034] The curved slide rail is designed to better accommodate the rotational movements of the human neck. When users need to adjust their head position or perform certain rotational movements, the curved slide rail provides a smoother, more natural transition, reducing friction and discomfort caused by improper slide rail shape.

[0035] In one specific embodiment, the first slide rail 50 has a first positioning groove 51, and the second slide rail 60 has a second positioning groove 61. The first positioning groove 51 is connected to the forehead fixing mechanism 30 to fix the position of the forehead fixing mechanism 30, and the second positioning groove 61 is connected to the chin fixing mechanism 40 to fix the position of the chin fixing mechanism 40.

[0036] Specifically, the design of the first slide rail 50 and the second slide rail 60 allows the forehead fixing mechanism 30 and the chin fixing mechanism 40 to slide and adjust within a certain range to adapt to the facial features of different users. The addition of the positioning groove ensures that these two mechanisms can be firmly fixed after adjustment, avoiding errors caused by sliding.

[0037] By combining the design of slide rails and positioning slots, this fixing device possesses sufficient flexibility to adapt to the needs of different users while ensuring the accuracy of the test results. This design makes the testing process more efficient and reliable.

[0038] In one specific embodiment, the forehead fixing mechanism 30 includes: a first slider 31, a telescopic component 32, and a forehead fixing member 33. The first slider 31 is sleeved within the first slide rail 50, and the telescopic component 32 is slidably connected to the first slide rail 50. The telescopic component 32 is perpendicularly connected to the first slider 31 and passes through the body 10 to the imaging cavity 11. The forehead fixing member 33 is rotatably connected to the telescopic component 32, and the forehead fixing member 33 is located within the imaging cavity 11 and conforms to the human forehead.

[0039] Specifically, the first slider 31 is fitted inside the first slide rail 50 and forms a sliding connection with the first slide rail 50. This design allows the forehead fixing mechanism 30 to move horizontally along the first slide rail 50 to accommodate the neck rotation movements of different users in order to capture different angles of their faces.

[0040] The first slider 31, serving as the connecting component between the forehead fixing mechanism 30 and the slide rail, plays a role in transmitting sliding and adjustment forces. It ensures the stability and accuracy of the forehead fixing mechanism 30 during the adjustment process.

[0041] The telescopic component 32 is vertically connected to the first slider 31 and extends through the body 10 into the imaging cavity 11. This design allows the forehead fixation mechanism 30 to be adjusted vertically to accommodate different users' forehead heights and tilt angles. The telescopic component 32 may employ a structure such as a spring, cylinder, or electric actuator to achieve flexible telescopic functionality.

[0042] The telescopic component 32 not only provides the forehead fixation mechanism 30 with vertical adjustment capability, but also ensures a close fit and stable fixation between the forehead fixation component 33 and the human forehead through its elastic or rigid characteristics.

[0043] The forehead fixation component 33 is rotatably connected to the telescopic component 32, located within the imaging cavity 11, and conforms to the human forehead. This design allows the forehead fixation component 33 to be rotated and adjusted within a certain range to accommodate different users' forehead shapes and tilt angles.

[0044] The forehead retainer 33 may be made of a soft, skin-friendly material to reduce pressure and discomfort on the forehead. Additionally, its surface may be designed with anti-slip textures or a shape that conforms to the curves of the human body to improve fixation and comfort.

[0045] In one specific embodiment, the telescopic assembly 32 further includes a housing 321 and a telescopic member 322. One end of the telescopic member 322 is sleeved on the housing 321, and the telescopic member 322 is slidably connected to the housing 321. The other end of the telescopic member 322 is rotatably connected to the forehead fixing member 33.

[0046] Specifically, the outer shell 321, as the main structure of the telescopic component 32, serves to support and protect the telescopic component 322. It is typically designed to be robust and durable, capable of withstanding certain external forces and pressures while maintaining the stability and integrity of the internal structure.

[0047] The shape of the housing 321 may be designed according to actual needs, but it usually has a certain degree of rigidity and strength. In terms of materials, the housing 321 may be made of metal, plastic or composite materials to meet different usage environments and requirements.

[0048] One end of the telescopic component 322 is fitted inside the outer casing 321 and forms a sliding connection with the outer casing 321. This design allows the telescopic component 322 to move vertically inside the outer casing 321, thereby driving the forehead fixing component 33 to adjust up and down. The other end of the telescopic component 322 is rotatably connected to the forehead fixing component 33. This rotatable connection design allows the forehead fixing component 33 to be adjusted within a certain range of angles to adapt to different users' forehead shapes and tilt angles.

[0049] The telescopic component 322 may employ structural forms such as a coil spring, a pneumatic cylinder, or an electric push rod to achieve flexible telescopic functionality. Each of these structural forms has its own advantages and disadvantages, but they can all, to a certain extent, meet the vertical adjustment requirements of the forehead fixing mechanism 30.

[0050] In one specific embodiment, the telescopic member 322 is provided with a pin portion 3221, and the outer shell 321 has a pin hole 3211 that matches the pin portion 3221. A plurality of pin holes 3211 are evenly arranged along the height direction of the telescopic component 32. The pin portion 3221 is connected to any of the pin holes 3211 to adjust the height position of the forehead fixing member 33.

[0051] Specifically, the pin 3221 is provided on the telescopic member 322, and is usually a protruding small post or pin. Its main function is to be inserted into the pin hole 3211 on the housing 321, thereby fixing the height position of the telescopic member 322 and the front fixing member 33.

[0052] The pin portion 3221 may be designed with different shapes and sizes to accommodate different pin holes 3211 and fixing requirements. At the same time, in order to ensure that the pin portion 3221 can be securely inserted into the pin hole 3211, it may also be equipped with auxiliary structures such as elastic snaps and threaded locking.

[0053] The pin holes 3211 are formed on the housing 321 and are generally evenly arranged along the height direction of the telescopic component 32. This arrangement allows the pin portion 3221 to be selectively inserted into the pin holes 3211 at different height positions, thereby realizing the height adjustment of the forehead fixing member 33.

[0054] The shape and size of the pin hole 3211 should match the pin part 3221 to ensure that they fit together tightly. At the same time, in order to increase the stability and durability of the pin hole 3211, it may adopt structural designs such as reinforcing ribs and chamfers.

[0055] When the user needs to adjust the height of the forehead fixing member 33, simply move the telescopic member 322 up and down along the outer casing 321 until the pin part 3221 aligns with the desired pin hole 3211. Then, insert the pin part 3221 into the pin hole 3211 and secure it. This operation is simple and convenient, and the user can adjust the height at any time according to their needs.

[0056] Since the pin holes 3211 are evenly arranged along the height direction of the telescopic component 32, the height adjustment range of the front fixing member 33 is limited. However, by reasonably designing the number and spacing of the pin holes 3211, the height adjustment needs of most users can be met.

[0057] In one specific embodiment, the chin fixing mechanism 40 includes a second slider 41 and a chin fixing member 42. The second slider 41 is sleeved on the second slide rail 60 and is slidably connected to the second slide rail 60. The chin fixing member 42 is perpendicularly connected to the second slider 41 and passes through the body 10 to the imaging cavity 11.

[0058] Specifically, the second slider 41 is fitted onto the second slide rail 60 and forms a sliding connection with the second slide rail 60. This design allows the chin fixing mechanism 40 to move horizontally along the second slide rail 60 to accommodate the chin position and width of different users.

[0059] The second slider 41, serving as the connecting component between the chin fixing mechanism 40 and the slide rail, plays a role in transmitting sliding and adjustment forces. It ensures the smoothness and accuracy of the chin fixing mechanism 40 during the adjustment process.

[0060] The chin retainer 42 is vertically connected to the second slider 41 and extends through the body 10 into the camera cavity 11. This design allows the chin retainer 42 to directly contact the user's chin and hold it in place with appropriate pressure. The chin retainer 42 may be made of a soft, skin-friendly material to reduce pressure and discomfort on the chin.

[0061] The shape of the chin retainer 42 may be designed according to actual needs, but it usually has a certain curvature and fit to adapt to the chin shape and size of different users. At the same time, the chin retainer 42 may also be equipped with adjustment devices, such as knobs, slide rails, etc., so that users can make fine adjustments according to their own needs.

[0062] In one specific embodiment, the first slider 31 is provided with a first positioning part 311 that matches the first positioning groove 51, and the first slide rail 50 is provided with the first positioning groove 51 at both ends and in the middle. The first positioning part 311 is connected to any of the first positioning grooves 51 to fix the position of the chin fixing mechanism 40.

[0063] Specifically, the chin fixing mechanism 40 slides on the first slide rail 50 via the first slider 31 to achieve position adjustment. In order to fix the chin fixing mechanism 40 in different positions, the first slider 31 is provided with a first positioning part 311, which can match and connect with the first positioning groove 51 opened on the first slide rail 50.

[0064] First positioning grooves 51 are provided at both ends and the middle position of the first slide rail 50. This means that the chin fixing mechanism 40 can be fixed at both ends and at least one middle position of the slide rail, thus providing a variety of shooting angle options.

[0065] Since the first positioning part 311 can selectively connect to any of the first positioning slots 51, the user can easily fix the chin fixing mechanism 40 in the desired position according to shooting needs. This design improves the flexibility and convenience of shooting.

[0066] The chin fixing mechanism 40 is stably fixed in multiple positions through the coordinated use of the first slider 31, the first slide rail 50, and the first positioning groove 51. This not only meets the needs of multi-angle shooting but also ensures user comfort and accuracy of shooting results during the shooting process.

[0067] In one specific embodiment, the second slider 41 is provided with a second positioning part 411 that matches the second positioning groove 61, and the second slide rail 60 is provided with the second positioning groove 61 at both ends and the middle, and the second positioning part 411 is connected to any of the second positioning grooves 61 to fix the position of the forehead fixing mechanism 30.

[0068] Specifically, second positioning grooves 61 are provided at both ends and the middle position of the second slide rail 60. This means that the forehead fixing mechanism 30 can be fixed at both ends and at least one middle position of the slide rail, thus providing a variety of shooting angle options.

[0069] Since the second positioning part 411 can selectively connect to any of the second positioning slots 61, the user can easily fix the forehead fixing mechanism 30 in the desired position according to shooting needs. This design improves the flexibility and convenience of shooting.

[0070] The forehead fixing mechanism 30 is stably fixed in multiple positions through the coordinated use of the second slider 41, the second slide rail 60, and the second positioning groove 61. This not only meets the needs of multi-angle shooting but also ensures user comfort and accuracy of shooting results during the shooting process.

[0071] Therefore, the aforementioned tongue and skin examination and fixation device 100 is designed to fit snugly against the human body via a forehead fixation mechanism 30 and a chin fixation mechanism 40 to stabilize the head, reducing blurry images or diagnostic errors caused by head movement. Simultaneously, when the human face rotates relative to the camera 20, the forehead and chin fixation mechanisms can slide accordingly, allowing for the capture of images from multiple angles, including frontal and side views.

[0072] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
