[0037] The following description describes preferred embodiments of the present invention; however, the foregoing description is intended to illustrate the general principles of the present invention and is not intended to limit the scope of the present invention. The scope of protection of the present invention shall be determined by the appended claims.

[0038] Please see Figure 1 , Figure 1This is a structural block diagram of the facial, tongue, and pulse diagnosis system 1000 provided in this embodiment of the present invention. The facial, tongue, and pulse diagnosis system 1000 includes a facial and tongue diagnostic instrument 100 and a pulse diagnostic instrument 200. The facial and tongue diagnostic instrument 100 and the pulse diagnostic instrument 200 are independently configured but communicatively connected. Therefore, based on the independent configuration of the facial and tongue diagnostic instrument 100 and the pulse diagnostic instrument 200, and the fact that the facial and tongue diagnostic instrument 100 can receive pulse information collected by the pulse diagnostic instrument 200, the facial and tongue diagnostic instrument 100 and the pulse diagnostic instrument 200 do not interfere with each other, thus improving the comprehensive analytical performance of the facial, tongue, and pulse diagnosis system 1000 and increasing the accuracy of the diagnostic results.

[0039] The facial and tongue diagnostic instrument 100 is equipped with a first communication module 1001. The pulse diagnostic instrument 200 is equipped with a second communication module 2001. The first communication module 1001 and the second communication module 2001 establish a communication connection. The facial and tongue diagnostic instrument 100 also includes a control module 1002. The control module 1002 is electrically connected to the first communication module 1001. The control module 1002 is used to receive and process the facial and tongue image information collected by the facial and tongue diagnostic instrument 100 and the pulse information collected by the pulse diagnostic instrument 200, thereby realizing the data transmission between the facial and tongue diagnostic instrument 100 and the pulse diagnostic instrument 200. Furthermore, the pulse information collected by the pulse diagnostic instrument 200 can be transmitted to the facial and tongue diagnostic instrument 100 for centralized monitoring through the second communication module 2001 and the first communication module 1001. This enables the facial and tongue pulse diagnostic system 1000 to perform multiple diagnostic functions, including observation (e.g., tongue and facial image information), auscultation (e.g., sound information such as voice, cough, and wheezing), inquiry (e.g., current symptoms and historical disease information reported by the patient), and palpation (e.g., pulse information).

[0040] In this embodiment, the first communication module 1001 and the second communication module 2001 establish a wireless communication connection. This achieves two benefits: firstly, it enables a wireless connection between the facial and tongue diagnostic instrument 100 and the pulse diagnostic instrument 200, preventing mutual interference during data collection and enhancing the mobility and flexibility of both instruments; secondly, it allows for contactless data transmission between them, improving hygiene and safety. The first communication module 1001 and the second communication module 2001 can be, but are not limited to, Wi-Fi modules, Bluetooth modules, or mobile communication modules such as 2G, 3G, 4G, and 5G. In other embodiments, the pulse diagnostic instrument 200 can also connect to the facial and tongue diagnostic instrument 100 via a cable. For example, in this embodiment, the first communication module 1001 and the second communication module 2001 are both configured as Bluetooth modules, and the facial and tongue diagnostic instrument 100 and the pulse diagnostic instrument 200 establish a communication connection via Bluetooth. Therefore, on the one hand, the low power consumption of the Bluetooth module improves the battery life of the facial and tongue diagnostic instrument 100 and the pulse diagnostic instrument 200; on the other hand, the establishment of a wireless communication connection between the facial and tongue diagnostic instrument 100 and the pulse diagnostic instrument 200 via the Bluetooth module enhances their mobility and flexibility, while also providing reliability and stability for data transmission. Of course, in some embodiments, the first communication module 1001 and the second communication module 2001 can also be configured as other communication modules, and this utility model does not impose specific limitations.

[0041] In this embodiment, the facial and tongue diagnostic instrument 100 can establish a communication connection with one pulse diagnostic instrument 200. In some embodiments, the facial and tongue diagnostic instrument 100 can establish a communication connection with multiple pulse diagnostic instruments 200. Within the same time period, the facial and tongue diagnostic instrument 100 only establishes a communication connection with one pulse diagnostic instrument 200. On the one hand, this prevents data crosstalk and mismatch, improves the accuracy of diagnostic conclusions, and avoids medical accidents; on the other hand, information such as tongue, face, pulse, and symptoms are collected at the same time point or within a very short time interval to reflect the physiological and pathological state of the human body at the same moment. Of course, in other embodiments, within the same time period, the facial and tongue diagnostic instrument 100 can establish a communication connection with multiple pulse diagnostic instruments 200. The facial and tongue information collected by the facial and tongue diagnostic instrument 100 and the pulse information collected by the multiple pulse diagnostic instruments 200 are associated and bound with the patient's identity information, thereby improving the diagnostic efficiency of the facial, tongue, and pulse diagnostic system 1000.

[0042] Please refer to the following: Figures 1 to 3 , Figure 2 yes Figure 1 A schematic diagram of the structure of the facial and tongue diagnostic instrument 100 in the facial and tongue pulse diagnosis system 1000; Figure 3 yes Figure 2This is an exploded view of a portion of the structure of a facial and tongue diagnostic instrument 100 from a first-view perspective. The facial and tongue diagnostic instrument 100 includes a main unit 10 and an image acquisition unit 50. The main unit 10 includes a housing 1, a first communication module 1001, a control module 1002, and a display 5. The housing 1 has a receiving cavity 101 and a display window 102 connected to the receiving cavity 101. The control module 1002 and the first communication module 1001 are disposed within the receiving cavity 101. The first communication module 1001 is electrically connected to the control module 1002 and is used to establish a communication connection with the second communication module 2001 of the pulse diagnostic instrument 200. The display 5 is mounted at the display window 102 and is electrically connected to the control module 1002. The image acquisition unit 50 is rotatably connected to the top of the housing 1 and is located outside the receiving cavity 101. Both the image acquisition unit 50 and the display 5 are located on the front side of the housing 1. The image acquisition unit 50 is electrically connected to the control module 1002 and is used to acquire facial and tongue image information of the patient. The control module 1002 is used to receive and process the facial and tongue image information acquired by the image acquisition device 50 and the pulse information acquired by the pulse diagnosis device 200, and to control the display 5 to display the facial and tongue image information and pulse information processed by the control module 1002.

[0043] The facial and tongue diagnostic instrument 100 provided in this embodiment of the utility model has two advantages. First, the host 10 is integrated into the facial and tongue diagnostic instrument 100, which facilitates its use in community hospitals, home visits, or remote consultation scenarios. Furthermore, it eliminates the need for an external computer connection, allowing the facial and tongue diagnostic instrument 100 to quickly enter the diagnostic process upon power-on, thus improving its diagnostic efficiency. The integrated structure of the host 10 and the image acquisition unit 50 also reduces the risk of connection failures. Second, based on the independent setup of the facial and tongue diagnostic instrument 100 and the pulse diagnosis instrument 200, and the host 10 of the facial and tongue diagnostic instrument 100... The device can receive pulse information collected by the pulse diagnostic instrument 200, thus preventing interference between the facial and tongue diagnostic instrument 100 and the pulse diagnostic instrument 200, improving the accuracy of the diagnostic results and enhancing the comprehensive analysis performance of the facial and tongue pulse diagnostic system 1000. Furthermore, the image acquisition device 50 is rotatably connected to the housing 1, allowing the image acquisition device 50 to adjust its imaging angle to suit users of different heights. It can correctly project key parts such as the face and tongue onto the camera area, improving the image quality acquired by the image acquisition device 50. Moreover, the acquisition of tongue and face images uses a single image acquisition device 50, resulting in a simple structure and cost savings.

[0044] It should be noted that, Figure 1 The purpose is merely to illustrate the setup between the host 10 and the image acquisition unit 50, and is not to make specific limitations on the connection positions, connection relationships and specific structures of each component. Figure 1This illustration of the facial and tongue diagnostic instrument 100 is merely a structural representation of an embodiment of the present invention and does not constitute a specific limitation on the facial and tongue diagnostic instrument 100. In other embodiments of the present invention, the facial and tongue diagnostic instrument 100 may include... Figure 1 The number of components shown may be more or less, or combinations of certain components, or different components. For example, the face and tongue diagnostic instrument 100 may also include, but is not limited to, a battery management system, connecting harnesses, etc.

[0045] The facial and tongue diagnostic instrument 100 also includes a damping hinge 60. The image acquisition unit 50 is rotatably connected to the housing 1 in a plane parallel to the height direction Z of the facial and tongue diagnostic instrument 100 via the damping hinge 60. Thus, on the one hand, the damping hinge 60 provides moderate resistance, preventing the image acquisition unit 50 from accidentally shifting due to slight patient movement or operator touch, and the image acquisition unit 50 hardly wobbles under the damping force after pitch angle adjustment, improving the stability of the image acquisition unit 50 at the moment of exposure and reducing the risk of image blurring; on the other hand, the damping hinge 60 eliminates the need for locking screws or additional fixing structures, allowing users to adjust and fix it instantly with one hand, simplifying the process, improving examination efficiency, extending equipment life, reducing maintenance costs, and preventing the image acquisition unit 50 from swaying left and right during pitch adjustment, thus improving the imaging alignment accuracy of the image acquisition unit 50.

[0046] Please refer to the following: Figure 3 and Figure 4 , Figure 4 yes Figure 3An exploded view of the damping hinge 60 of the facial tongue diagnostic instrument 100. The image acquisition unit 50 includes a camera housing 51 and a camera 52. The camera 52 is mounted on the camera housing 51. The damping hinge 60 includes a first connector 61, a second connector 62, and a damping element 63. The damping element 63 includes a rotating shaft 631, a first damping disc 632, and a second damping disc 633. The first connector 61 is fixedly connected to the camera housing 51 and the first damping disc 632. The second connector 62 is fixedly connected to the housing 51 and the second damping disc 633. The first damping disc 632 is rotatably connected to the rotating shaft 631. The second damping disc 633 and the first damping disc 632 are arranged sequentially along the axial direction of the rotating shaft 631 and abut against the first damping disc 632. Therefore, on the one hand, when the external torque force is applied to the camera housing 51, the camera housing 51 drives the first connecting member 61 and the first damping disk 632 to rotate relative to the rotating shaft 631, and generates a damping force between them and the second damping disk 633. As a result, the image acquisition device 50 hardly shakes after the pitch angle is adjusted, which improves the stability of the image acquisition device 50 at the moment of exposure and reduces the risk of image blurring. On the other hand, the first damping disk 632 and the second damping disk 633 can limit the lateral displacement of the image acquisition device 50, prevent the image acquisition device 50 from swaying left and right during pitch adjustment, and improve the imaging alignment accuracy of the image acquisition device 50.

[0047] In this embodiment, the first connector 61 is detachably fixed to the camera housing 51, thereby enabling quick assembly and disassembly between the first connector 61 of the damping hinge 60 and the camera housing 51, facilitating later maintenance or replacement. The first connector 61 can be detachably fixed to the camera housing 51 by means of screws or clips. Of course, in some embodiments, the first connector 61 and the camera housing 51 can also be non-detachably fixed, that is, the first connector 61 is part of the structure of the camera housing 51.

[0048] Exemplarily, in this embodiment, the second connector 62 is indirectly and fixedly connected to the housing 1. The main unit 10 also includes the housing 1 and a support frame 2 disposed within the housing 1. One end of the support frame 2 is fixedly connected to the housing 1, and the other end of the support frame 2 is fixedly connected to the second connector 62. The image acquisition device 50 is detachably connected to the top of the housing 1 and located outside the accommodating cavity 101, thereby facilitating the disassembly, maintenance, and replacement of the image acquisition device 50, and improving the operational flexibility of the image acquisition device 50. Of course, in some embodiments, the image acquisition device 50 may also be non-detachably connected to the housing 1, and this embodiment of the present invention does not specifically limit this. In other embodiments, the support frame 2 may be omitted from the main unit 10, that is, the second connector 62 is directly and fixedly connected to the housing 1.

[0049] In this embodiment, the second connector 62 is detachably fixed to the housing 1, thereby enabling quick assembly and disassembly between the second connector 62 of the damping hinge 60 and the housing 1, facilitating later maintenance or replacement. The second connector 62 can be detachably fixed to the housing 1 by means of screws or clips. Of course, in some embodiments, the second connector 62 and the housing 1 can also be non-detachably fixed, that is, the first connector 61 is part of the structure of the housing 1.

[0050] Please refer to the following: Figures 4 to 7 , Figure 5 yes Figure 2 Front view of the facial tongue diagnostic instrument 100; Figure 6 yes Figure 5 A cross-sectional view of the facial tongue diagnostic instrument 100 along line AA; Figure 7 yes Figure 6 This is an enlarged view of part I of the facial tongue diagnostic instrument 100. In this embodiment, a mounting groove 5101 is recessed in the outer wall of the camera housing 51, and the first connector 61 is detachably disposed within the mounting groove 5101. Therefore, by placing the connector within the mounting groove 5101, the damping hinge 60 is embedded in the camera housing 51. On the one hand, this reduces external protrusions, making the overall device thinner and improving the aesthetic appearance of the facial tongue diagnostic instrument 100. On the other hand, the detachable first connector 61 within the mounting groove 5101 allows for quick assembly and disassembly between the first connector 61 of the damping hinge 60 and the camera housing 51, facilitating later maintenance or replacement. Of course, in some embodiments, the first connector 61 may also be non-detachably connected to the camera housing 51.

[0051] Please refer to the following: Figure 4 , Figure 7 and Figure 8 , Figure 8 yes Figure 5 A cross-sectional view of the facial tongue diagnostic instrument 100 along line BB. In some embodiments, the first connector 61 includes a positioning part 611 and a first connecting part 612. The groove wall of the mounting groove 5101 is recessed to form a positioning groove 5103. The positioning part 611 is disposed in the positioning groove 5103. The first connecting part 612 is fixedly connected to the positioning part 611 and the first damping disc 632. Thus, based on the fixed fit between the positioning groove 5103 and the positioning part 611, the assembly efficiency and assembly yield of the connector with the housing 1 and the damping hinge 60 are improved, and the problem of the image acquisition unit 50 swinging relative to the damping hinge 60 is avoided, thereby improving the imaging alignment accuracy of the image acquisition unit 50.

[0052] The second connector 62 is fixedly connected to the housing 1 via the support frame 2. The support frame 2 is fixedly disposed within the housing 1. Specifically, the support frame 2 is disposed within the receiving cavity 101. The housing 1 is also provided with a through hole 103 communicating with the receiving cavity 101. The second connector 62 includes a fixing part 621 and a second connecting part 622. One end of the second connecting part 622 passes through the through hole 103 and is fixedly connected to the second damping disc 633; ​​the fixing part 621 is fixedly connected to the other end of the second connector 62 and is fixedly connected to the support frame 2. Thus, on the one hand, the structure of the support frame 2 is hidden within the receiving cavity 101, thereby reducing the external volume of the facial tongue diagnostic instrument 100 and enabling the replacement and maintenance of the damping hinge 60 without disassembling the housing 1, thus reducing maintenance costs; on the other hand, the receiving cavity 101 provides a closed rigid support for the support frame 2, reducing the interference of external vibrations on the image acquisition unit 50 and improving the imaging alignment accuracy of the image acquisition unit 50.

[0053] Please refer to the following: Figure 3 , Figure 4 and Figure 7 A limiting protrusion 111 is provided on the outer wall of the housing 1 facing the image acquisition unit 50. A through hole 103 passes through the two end faces of the limiting protrusion 111. The end of the limiting protrusion 111 facing away from the housing 1 is inserted into the mounting groove 5101. The limiting protrusion 111 is used to limit the pitch angle range of the image acquisition unit 50 relative to the housing 1. Thus, on the one hand, the contact between the limiting protrusion 111 and the groove wall of the mounting groove 5101 forms a mechanical stop, directly limiting the rotation angle of the image acquisition unit 50 and avoiding problems such as cable pulling or mechanical interference caused by over-adjustment; on the other hand, when the image acquisition unit 50 rotates to the limit angle, the impact force is transmitted to the entire housing 1 through the limiting protrusion 111, rather than being borne only by the hinge shaft, reducing local wear; furthermore, the nested design of the limiting protrusion 111 and the mounting groove 5101 eliminates the need for an external limiting block, keeping the appearance of the device simple and improving the aesthetics of the face and tongue diagnostic instrument 100.

[0054] In this embodiment, a portion of the damping hinge component 60 is located within the mounting groove 5101, while the remaining portion is located within the through hole 103. Thus, the damping hinge component 60 is concealed within the mounting groove 5101 and the through hole 103, resulting in a compact structure and improved space utilization. Furthermore, the damping hinge component 60 can be disassembled without removing the housing 1, facilitating its installation, maintenance, or replacement.

[0055] For example, in this embodiment, the plane containing the first damping disc 632 is parallel to the plane in the height direction Z of the face tongue diagnostic instrument 100, thereby enabling the image acquisition device 50 to be rotatably connected to the housing 1 in the plane parallel to the height direction Z of the face tongue diagnostic instrument 100 via the damping hinge 60. This prevents the image acquisition device 50 from swaying left or right during pitch adjustment, improving the imaging alignment accuracy of the image acquisition device 50.

[0056] In some embodiments, the end of the limiting protrusion 111 facing the image acquisition device 50 is provided with a clearance notch 112. The clearance notch 112 is configured to avoid interference with the rotating shaft 631, and the central axis of the rotating shaft 631 is perpendicular to the extension direction of the through hole 103. Thus, the clearance notch 112 configured between the rotating shaft 631 and the limiting protrusion 111 avoids interference between the image acquisition device 50 and the housing 1 when the image acquisition device 50 rotates relative to the housing 1, improving the reliability and safety of the rotation of the image acquisition device 50; on the other hand, it improves the space utilization between the damping hinge 60, the image acquisition device 50, and the host 10, resulting in a simple and compact structure; furthermore, the central axis of the rotating shaft 631 is perpendicular to the extension direction of the through hole 103, making the motion trajectory plane of the image acquisition device 50 orthogonal to the centerline of the rotating shaft 631, thereby limiting the pitch adjustment orientation of the image acquisition device 50 and improving space utilization.

[0057] The shape of the clearance notch 112 is adapted to the shape of the rotating shaft 631. Specifically, the shape of the clearance notch 112 is roughly semi-circular, which facilitates the rotating shaft 631 to pass through the clearance notch 112, improves assembly and disassembly efficiency, and the edge of the clearance notch 112 is rounded to reduce the impact stress concentration when the rotating shaft 631 is limited, and prevent the housing 1 from cracking or metal fatigue.

[0058] In some embodiments, the two ends of the pivot 631 are located within the clearance notch 112. Thus, the clearance notch 112 allows the two ends of the pivot 631 to be inserted, so that the pivot 631 will not collide hard with the limiting protrusion 111, eliminating the risk of mechanical jamming, and reducing the external protrusion structure, making the overall device thinner.

[0059] In this embodiment, the mounting slot 5101 is configured as a gradually expanding slot. An oblique opening 5102 is provided on the open side of the mounting slot 5101. When the image acquisition device 50 rotates relative to the housing 1 until the optical axis of the camera 52 is parallel to the horizontal plane, the oblique opening 5102 is tilted downwards relative to the optical axis of the camera 52, away from the housing 1. On one hand, by setting the slotting angle and depth of the mounting slot 5101, the tilt range of different devices can be flexibly defined to adapt to different application scenarios such as children and / or adults. On the other hand, based on the fact that the oblique opening 5102 is tilted downwards relative to the optical axis of the camera 52, away from the housing 1, when the image acquisition device 50 rotates relative to the housing 1 until the optical axis of the camera 52 is parallel to the horizontal plane, the maximum elevation angle is less than the maximum tilt angle, preventing over-adjustment. Furthermore, the oblique opening 5102 provides a progressive tolerance space during the tilt rotation of the camera 52, conforming to user operating habits and improving the adjustment efficiency of the tilt angle of the image acquisition device 50.

[0060] For example, in this embodiment, when the image acquisition device 50 rotates relative to the housing 1 to the first position, the optical axis of the camera 52 is parallel to the horizontal plane. When the image acquisition device 50 rotates relative to the housing 1 to the second position, the angle between the optical axis of the camera 52 and the horizontal plane is the first angle. When the image acquisition device 50 rotates relative to the housing 1 to the third position, the angle between the optical axis of the camera 52 and the horizontal plane is the second angle. The first angle is smaller than the second angle. The first position is located between the second and third positions, and the second position is located above the third position. Therefore, by setting the maximum elevation angle of the image acquisition device 50 to be smaller than the maximum depression angle, excessive adjustment of the elevation angle of the image acquisition device 50 is prevented. Furthermore, the oblique opening 5102 provides a progressive tolerance space during the tilt rotation of the camera 52, conforming to user operating habits and improving the adjustment efficiency of the elevation angle of the image acquisition device 50.

[0061] Both the housing 1 and the camera housing 51 are made of plastic. Therefore, on the one hand, by making the housing 1 a plastic structure, the facial tongue diagnostic instrument 100 is made lighter, and the housing 1 can be made more flexible in structural design through injection molding; on the other hand, the natural insulating properties of plastic avoid the static discomfort that may be caused by metal housings, and also reduce production costs.

[0062] The main unit 10 also includes a support frame 3 disposed within the housing 1. The support frame 3 is fixedly connected to the housing 1 and is configured as a sheet metal frame. A support frame 2 is located above the support frame 3. One end of the support frame 2 is fixedly connected to the second connector 62 and is bent relative to the second connector 62. The other end of the support frame 2 is fixedly connected to the support frame 3. Therefore, on the one hand, by configuring the support frame 2 as a sheet metal frame, and by covering and fixing the housing 1 to the outside of the support frame 3, and by mounting the support frame 2 on the sheet metal frame made of metal, the support frame 3 can provide rigid support for the stress points of the various functional components of the facial tongue diagnostic instrument 100, avoiding the problem of creep deformation caused by the frequent adjustment of the pitch angle of the image acquisition unit 50 in the plastic housing, thus improving the overall structural strength of the host 10. Furthermore, the housing 1 can absorb the mechanical vibration generated by the rotation of the image acquisition unit 50 relative to the housing 1 and the mechanical vibration generated by the host 10 during operation, and improve the stability of the center of gravity of the host 10. On the other hand, the support frame 2 is bent and connected to the second connector 62, so that the support frame 2 extends toward the side of the support frame 3 and is fixed to the housing 1 through the support frame 3. The second connector 62 extends toward the side closer to the camera housing 51, thus the support frame 2 and the second connector 62 are connected to form a three-dimensional support frame, thereby optimizing the torque distribution and reducing the torque generated by the pitch operation, and extending the service life of the facial tongue diagnostic instrument 100.

[0063] In this embodiment, one end of the support frame 2 is fixedly connected to the second connector 62 to form an L-shaped structure. Of course, in some other embodiments, the support frame 2 can be omitted from the main unit 10, and the second connector 62 can be directly fixedly connected to the housing 1. The housing 1 can also be a metal structure; this embodiment of the invention does not impose specific limitations.

[0064] The support frame 2 is detachably connected between the bearing frame 3 and the second connecting member 62, thereby facilitating the assembly, disassembly, and replacement of the support frame 2 and the damping hinge member 60. Of course, the support frame 2 can also be non-detachably fixedly connected to at least one of the bearing frame 3 and the second connecting member 62; this utility model does not impose any specific limitations.

[0065] In some embodiments, the image acquisition device 50 further includes a supplementary lighting element 53. The supplementary lighting element 53 is disposed within the camera housing 51. The supplementary lighting element 53 is used to provide supplementary lighting for the camera 52's capture. Therefore, the supplementary lighting element 53 improves the image quality captured by the camera 52. The orthographic projection of the supplementary lighting element 53 in its light-emitting direction is offset from the orthographic projection of the image acquisition device 50 in the same direction, thereby preventing the image acquisition device 50 from blocking the supplementary lighting light from the supplementary lighting element 53 and improving the supplementary lighting effect of the supplementary lighting element 53.

[0066] Please refer to the following: Figures 8 to 9 , Figure 9 yes Figure 2 An exploded view of the image acquisition unit 50 of the facial tongue diagnostic instrument 100. The supplementary lighting component 53 includes a light panel 531 and a plurality of supplementary lights 532 disposed on the light panel 531. The plurality of supplementary lights 532 are spaced apart along the circumferential direction surrounding the optical axis of the camera 52, thereby forming uniform ring illumination, reducing shadows, improving the uniformity of supplementary lighting in the surrounding environment of the camera 52, and improving the shooting effect of the camera 52. In this embodiment, the supplementary lights 532 can be arranged to form a preset pattern. The preset pattern may include, but is not limited to, logo patterns, decorative patterns, or ambient patterns, etc.

[0067] A light-transmitting section 5121 is provided at the position corresponding to the supplementary lighting, thereby enabling the light from the supplementary lighting component 53 to be directed towards the outside of the camera housing 51. The light-transmitting section 5121 can be made of a light-transmitting material. In this embodiment, the camera housing 51 includes a main housing 511 and a light-transmitting shell 512. The light-transmitting shell 512 is fixedly connected to the main housing 511, and the exposed portion of the light-transmitting shell 512 relative to the main housing 511 is directly opposite to the area corresponding to the multiple supplementary lighting units 532. Specifically, the main housing 511 is provided with a receiving cavity 5104 and a light-transmitting hole 5105 communicating with the receiving cavity 5104. The camera 52, the supplementary lighting component 53, and the light-transmitting shell 512 are disposed within the receiving cavity 5104. The main housing 511 includes a front camera shell 5111 and a rear camera shell 5112. The front camera housing 5111 and the rear camera housing 5112 are detachably connected, forming a storage cavity 5104. This facilitates the assembly, disassembly, and maintenance of the internal structure of the image acquisition device 50. For example, the front camera housing 5111 and the rear camera housing 5112 can be detachably fixed together using a snap-fit ​​structure, screw locking, magnetic adsorption structure, etc. Of course, in some embodiments, the main body housing 511 includes a top camera housing and a bottom camera housing. The top camera housing and the bottom camera housing are detachably connected, forming a storage cavity 5104. The configuration of the main body housing 511 can be set according to the actual situation, and this utility model embodiment does not impose specific limitations.

[0068] The camera 52 is located on the side of the light-transmitting housing 512 facing away from the supplementary lighting element 53. Specifically, the camera 52 is disposed between the camera front housing 5111 and the light-transmitting housing 512. In this embodiment, the inner sidewall of the camera front housing 5111 facing the supplementary lighting element 53 is provided with a connecting groove 5108 and a light-emitting hole 5109. The camera 52 is embedded in the connecting groove 5108. The lens element of the camera 52 is aligned with the light-emitting hole 5109.

[0069] In some embodiments, the camera housing 51 further includes a protective shell 513. The protective shell 513 is fixedly connected to the main body housing 511 and / or the light-transmitting shell 512, and is used to cover the camera 52, thereby reducing wear on the lens of the camera 52 and extending the service life of the image acquisition unit 50. Exemplarily, in this embodiment, the protective shell 513 is fixedly connected to the main body housing 511 and is used to cover the light-emitting hole 5109.

[0070] A light-transmitting shell 512 is at least partially disposed at the light-transmitting hole 5105. The light-transmitting shell 512 includes a light-transmitting section 5121 and a non-light-transmitting section 5122 fixedly connected to the light-transmitting section 5121. The light-transmitting section 5121 is sealed within the light-transmitting hole 5105. The non-light-transmitting section 5122 is located outside the light-transmitting hole 5105 and is fixedly connected to the main shell 511. Of course, in some embodiments, the non-light-transmitting section 5122 may be omitted from the light-transmitting shell 512, meaning the light-transmitting shell 512 may only include the light-transmitting section 5121.

[0071] It should be noted that the light-transmitting section 5121 and the opaque section 5122 are relative terms. The light-transmitting section 5121 described herein refers to the portion of the light-transmitting shell 512 that allows the light emitted by the supplementary lighting element 53 to pass through. The opaque section 5122 described herein refers to the portion of the light-transmitting shell 512 that prevents the light emitted by the supplementary lighting element 53 from passing through. The opaque section 5122 can be made of either an opaque or light-transmitting material.

[0072] Please refer to the following: Figures 8 to 10 , Figure 10 yes Figure 2 An exploded view of a portion of the structure of the facial and tongue diagnostic instrument 100 from a second perspective. In some embodiments, a clearance groove 5120 is provided in the area of ​​the light-transmitting housing 512 corresponding to the supplementary light 532. The supplementary light 532 is accommodated within the clearance groove 5120. Thus, on the one hand, the space utilization of the supplementary light component 53 is improved, realizing the miniaturization design of the image acquisition device 50; on the other hand, interference between the supplementary light 532 and the light-transmitting housing 512 is avoided during assembly, and the light provided by the supplementary light component 53 is guided to illuminate the outside of the camera housing 51.

[0073] The image acquisition device 50 also includes a camera circuit board 54. The camera circuit board 54 is fixedly installed inside the camera housing 51. The camera circuit board 54 is located inside the receiving cavity 5104. The camera 52 is connected to the camera circuit board 54 and is used to control the camera parameters of the camera 52 and process the image data acquired by the camera 52. In this embodiment, in the light-emitting direction of the supplementary light element 53, the supplementary light element 53 is disposed between the camera circuit board 54 and the camera 52, thereby avoiding the camera circuit board 54 blocking the light of the supplementary light element 53. Specifically, the camera 52 is disposed on the side of the light-transmitting shell 512 facing away from the supplementary light element 53 in the light-emitting direction of the supplementary light element 53. The image acquisition device 50 also includes a flexible circuit board 55. One end of the flexible circuit board 55 passes through the supplementary light element 53 and the light-transmitting shell 512 in sequence and is connected to the camera 52. The other end of the flexible circuit board 55 is connected to the camera circuit board 54. Both the lamp plate 531 of the supplementary light element 53 and the light-transmitting shell 512 are provided with wiring holes 5106. The flexible circuit board 55 is disposed within the wiring hole 5106. Of course, in some embodiments, the camera circuit board 54 can also be electrically connected to the supplementary lighting element 53 and used to control the supplementary lighting parameters of the supplementary lighting element 53.

[0074] In some embodiments, the image acquisition device 50 further includes a heat sink 56. The heat sink 56 is fixedly mounted on the camera housing 51 and located within the receiving cavity 5104. A heat-conducting sheet 561 is provided on the side of the heat sink 56 facing the supplementary lighting element 53. The heat-conducting sheet 561 is used for thermally conductive connection with the lamp plate 531 of the supplementary lighting element 53, thereby achieving heat dissipation for the supplementary lighting element 53. The camera circuit board 54 is located on the side of the heat sink 56 facing away from the camera 52, thereby avoiding the problem of heat generated by the camera circuit board 54 being conducted to the lamp plate 531 and damaging the supplementary lighting element 53, and extending the service life of the supplementary lighting element 53. The heat sink 56 has a recess 5601 at the bottom of the heat-conducting sheet 561, and the end of the flexible circuit board 55 away from the camera 52 passes through the recess 5601 and is electrically connected to the camera circuit board 54. Of course, in some embodiments, the heat sink 56 has a recess 5601 at a fixed part of the heat-conducting sheet 561, and this embodiment of the present invention does not specifically limit this.

[0075] In some embodiments, the camera housing 51 is further provided with at least one heat dissipation hole 5107 communicating with the storage cavity 5104 and the external environment, thereby increasing the heat exchange efficiency between the storage cavity 5104 and the outside air and improving the heat dissipation effect of the image acquisition device 50. The heat dissipation hole 5107 is provided on the side of the camera housing 51 near the housing 1, thereby improving the aesthetics of the image acquisition device 50.

[0076] In some embodiments, the image acquisition device 50 further includes a dimming element 57. The dimming element 57 is fixedly connected to the camera housing 51 and disposed on the light emission path of the supplementary light element 53. Thus, the dimming element 57 is located on the supplementary light emission path to scatter, focus, or polarize the light provided by the supplementary light element 53, avoiding the problem of local overexposure or glare of the camera 52 caused by direct light from the supplementary light element 53, thereby improving the supplementary lighting effect of the supplementary light element 53 and thus improving the image quality of the image acquisition device 50.

[0077] In this embodiment, the dimming element 57 is disposed on the light-transmitting shell 512, thereby reducing the processing difficulty of the dimming element 57. For example, the dimming material of the dimming element 57 can be formed on the surface of the light-transmitting shell 512 by coating or screen printing, or the dimming material of the dimming element 57 can also be formed on the surface of the light-transmitting shell 512 by coating; or the dimming material of the dimming element 57 can be mixed in the light-transmitting shell 512. The setting method of the dimming element 57 can be set according to the actual situation, and this embodiment of the utility model does not make specific limitations. The dimming material of the dimming element 57 may include at least one of the following: a light-diffusing material, a scattering material, a focusing material, a polarizing material, a color-tuning and / or dimming material. In the example, the dimming material is a light-diffusing material. The light-diffusing material may include, but is not limited to, fluorescent materials. The color-tuning and / or dimming material includes at least one of photochromic materials and photoluminescent materials. In this embodiment, the dimming element 57 is disposed within the clearance groove 5120, thereby improving the space utilization of the dimming element 57 and realizing the miniaturization design of the image acquisition device 50. Of course, in some embodiments, the dimming element 57 is disposed on the main body shell 511. The method of setting the dimming element 57 on the light-transmitting shell 512 is the same as the method of setting the dimming element 57 on the main body shell 511, and will not be described again here.

[0078] In some embodiments, the image acquisition device 50 further includes a light sensor 58. The light sensor 58 is disposed on the side of the camera housing 51 facing the housing 1 and exposed relative to the housing 1. The light sensor 58 is electrically connected to the control module 1002 and is used to detect the ambient light information of the image acquisition device 50. The control module 1002 is used to control the supplementary lighting parameters of the supplementary lighting component 53 according to the ambient light information. Therefore, on the one hand, by placing the light sensor 58 on the side of the camera housing 51 facing the casing 1, that is, the light sensor 58 is located on the side of the camera housing 51 away from the supplementary light component 53, the ambient light sensed by the light sensor 58 is consistent with the ambient light direction sensed by the user's face, preventing direct or reflected light from the supplementary light component 53 from interfering with the reading of the light sensor 58, thus improving the detection accuracy of the light sensor 58 for the ambient light information of the camera 52. By distinguishing between ambient light and supplementary light intensity, the control module 1002 can more accurately and dynamically adjust the supplementary light parameters of the supplementary light component 53, avoiding overexposure or underexposure of the camera 52 and improving the image quality captured by the camera 52. On the other hand, the supplementary light component 53 can automatically switch the supplementary light mode according to the ambient light intensity, improving the supplementary light effect. Furthermore, the arrangement of the light sensor 58 away from the supplementary light component 53 can reduce internal circuit interference and simplify the optical path design.

[0079] Please refer to it again. Figure 3 For example, in this embodiment, the housing 1 includes a front housing 110 and a rear housing 120. The front housing 110 and the rear housing 120 are fixedly connected and enclose a cavity 101. The front housing 110 and the rear housing 120 are detachably fitted and fixed, thereby facilitating the assembly, maintenance, and replacement of internal components of the main unit 10. For example, the front housing 110 and the rear housing 120 can be detachably fixed together by means of a snap-fit ​​structure, screw locking, magnetic adsorption structure, etc. Of course, in some embodiments, the housing 1 includes an upper housing and a lower housing. The upper housing and the lower housing are detachably connected and form the cavity 101. It should be noted that the configuration of the housing 1 can be set according to the actual situation, and this embodiment of the utility model does not impose a specific limitation.

[0080] In some embodiments, the main unit rear cover 120 includes a first cover 121, a second cover 122, and a third cover 123. The third cover 123 is connected between the first cover 121 and the second cover 122, and the first cover 121 and the second cover 122 are located between the main unit front cover 110 and the third cover 123. The first cover 121, the second cover 122, and the third cover 123 are detachably connected to each other, thereby reducing the processing difficulty of the housing 1.

[0081] In this embodiment, the housing 1 also includes a main unit bottom shell 130. The main unit bottom shell 130 is fixedly connected to the main unit front shell 110 and the main unit rear shell 120, forming an accommodating cavity 101. The main unit bottom shell 130 is detachably fitted and fixed to the main unit front shell 110 and the main unit rear shell 120, thereby facilitating the assembly, maintenance, and replacement of internal components of the main unit 10. For example, the main unit bottom shell 130 can be detachably fixed together with the main unit front shell 110 and the main unit rear shell 120 through a snap-fit ​​structure, screw locking, magnetic adsorption structure, etc. Of course, in some embodiments, the main unit bottom shell 130 can be omitted from the housing 1, that is, the housing 1 only includes the main unit front shell 110 and the main unit rear shell 120. It should be noted that the structure and connection method of the housing 1 can be set according to the actual situation, and this utility model embodiment does not make specific limitations.

[0082] The image acquisition device 50 is mounted on the top of the front casing 110 of the main unit, facilitating the acquisition of a superior image of the tongue that conforms to the standards of traditional Chinese medicine tongue diagnosis, avoiding distortion and obstruction, and conforming to ergonomic design, making the operation of the patient extending their tongue and the medical staff holding and aiming more natural, efficient, and accurate. The display 5 and the image acquisition device 50 are located on the front casing 110 of the main unit, so that the display 5 can provide users with visual information and easily remind users to maintain the correct posture when the image acquisition device 50 is performing the acquisition work.

[0083] For example, in this embodiment, the main unit 10 also includes an energy storage component 6. The energy storage component 6 is mounted on the support frame 3 and located at the bottom of the housing 1. Thus, on the one hand, the energy storage component 6 is mounted on the housing 1 via the support frame 3, thereby securing the battery and preventing problems such as loosening, poor contact, or even short circuits caused by the movement or fall of the facial and tongue diagnostic instrument 100; on the other hand, the energy storage component 6 is mounted at the bottom of the housing 1, thereby lowering the center of gravity of the main unit 10 and preventing the image acquisition unit 50 from tipping over when adjusting the pitch angle; furthermore, the built-in energy storage component 6 eliminates the constraints of the power cord, making it convenient for medical staff or patients to operate, improving the convenience of the facial and tongue diagnostic instrument 100, and enabling flexible use in environments such as clinics, wards, or outdoors.

[0084] The energy storage device 6 can be configured as a rechargeable energy storage structure or a disposable energy storage structure. A rechargeable energy storage structure may include, but is not limited to, a rechargeable capacitor or a rechargeable battery. Exemplarily, in this embodiment, the energy storage device 6 is configured as a rechargeable energy storage structure.

[0085] Please refer to it again. Figure 3 and Figure 10In some embodiments, a charging interface 7 is provided on the housing 1. The charging interface 7 is used to connect to an external power source, thereby providing energy to the host 10 and enabling the host 10 to operate normally. The charging interface 7 can be electrically connected to the energy storage device 6, thereby charging the energy storage device 6. The charging interface 7 is located on the side of the housing 1 facing away from the display 5, thereby avoiding the problem of the external power source and the charging interface 7 becoming loose due to the user bumping the connecting cable, improving the safety and reliability of the facial tongue diagnostic instrument 100, as well as improving the aesthetics of the facial tongue diagnostic instrument 100. Of course, in some other embodiments, the charging structure can also be set independently of the energy storage device 6, so that the host 10 can be connected to an external power source through the charging interface 7.

[0086] The charging port 7 is located on the rear shell 120 of the main unit. Specifically, the charging port 7 is located at the bottom of the third shell 123. Therefore, by placing the charging port 7 at the bottom of the shell 1, the charging cable can hang down naturally, making the facial and tongue diagnostic device 100 more stable when charging while lying flat, and preventing the charging cable from tripping the user. The charging port 7 can be located in the middle of the third shell 123 or other positions; this embodiment of the invention does not specifically limit the location of the charging port 7.

[0087] In some embodiments, the face and tongue diagnostic device 100 further includes a microphone 8. The microphone 8 is disposed on the top of the housing 1 and located below the image acquisition device 50. A microphone hole 104 is also provided on the housing 1 corresponding to the position of the microphone 8. When the image acquisition device 50 is rotated relative to the housing 1 to its maximum tilt angle position, the camera housing 51 and the microphone hole 104 are positioned out of alignment, and the projection of the image acquisition device 50 in the projection plane perpendicular to the height direction Z of the face and tongue diagnostic device 100 covers the projection of the microphone hole 104 in the projection plane perpendicular to the height direction Z of the face and tongue diagnostic device 100. In other words, when the image acquisition device 50 is rotated relative to the housing 1 to a third position, the camera housing 51 and the microphone hole 104 are positioned out of alignment. Therefore, on the one hand, when the image acquisition device 50 is rotated to its maximum tilt angle, the camera housing 51 and the microphone hole 104 are arranged to avoid each other, thus maintaining the unobstructed sound acquisition channel and avoiding sound distortion or blockage of the microphone hole 104 due to structural collision. Moreover, the tilt adjustment range is not limited by the position of the microphone 8, so that the image acquisition device 50 can cover a wider angle. On the other hand, by placing the image acquisition device 50 and the microphone 8 on the top of the housing 1, which is close to the patient's mouth and face, the quality of image and sound acquisition is improved. Furthermore, the microphone hole 104 is naturally blocked by the camera housing 51, which improves the aesthetics of the facial and tongue diagnostic instrument 100. The camera housing 51 can also prevent contaminants such as oral droplets and tongue coating from splashing into the microphone hole 104, reducing the risk of microbial accumulation. In addition, the gap between the camera housing 51 and the housing 1 forms a Helmholtz resonant cavity, which reduces the interference of environmental noise and improves the sound reception effect of the microphone 8.

[0088] It should be noted that the height direction Z refers to the direction perpendicular to the support platform, which is used to place the facial and tongue diagnostic instrument 100. The front side of the housing 1 refers to the side of the facial and tongue diagnostic instrument 100 facing the subject when taking a picture of the subject's facial and tongue, and the rear side of the housing 1 refers to the side of the facial and tongue diagnostic instrument 100 facing away from the subject when taking a picture of the subject's facial and tongue.

[0089] In some embodiments, the main unit 10 further includes a switch 11. The switch 11 is disposed on the rear side of the housing 1 and is electrically connected to the control module 1002. Thus, by placing the switch 11 on the rear side of the housing 1, on the one hand, the problem of accidental contact of the switch 11 causing abnormal start-up and shutdown of the facial diagnostic instrument 100 is avoided; on the other hand, the simplicity and aesthetics of the front panel of the housing 1 are improved, and the front panel of the housing 1 can provide sufficient installation space for other functional components, thus optimizing the overall structural layout.

[0090] The switch 11 is disposed on the rear shell 120 of the main unit. Specifically, the switch 11 is disposed on the top of the third shell 123. Thus, the switch 11 is disposed on the top of the shell 1, facilitating user operation and conforming to ergonomic design. The switch 11 can also be disposed in the middle of the third shell 123 or other positions; this embodiment of the invention does not impose specific limitations. For example, the switch 11 can also be disposed on the front shell 110 of the main unit. The switch 11 can also be integrated into the display 5. Of course, in some embodiments, the switch 11 can be omitted. The display 5 displays virtual buttons to control the power on and power off of the main unit 10.

[0091] In some embodiments, the host 10 further includes a speaker 4. The speaker 4 is disposed at the bottom of the housing 1. The display 5 is located between the speaker 4 and the microphone 8. The orthographic projection of the image acquisition unit 50 on the housing 1 obstructs the orthographic projection of the microphone 8 on the housing 1, and the image acquisition unit 50 and the microphone 8 are arranged to avoid each other. Therefore, on the one hand, the long-distance separation between the speaker 4 and the microphone 8 can effectively reduce feedback and prevent the sound output by the speaker 4 from being picked up by the microphone 8 a second time; on the other hand, the display 5 is located between the speaker 4 and the microphone 8, and the display 5 can act as a physical isolation barrier to reduce electromagnetic interference between electronic components; the microphone 8 is set at the top of the front shell 110 of the main unit, so that the microphone 8 is closer to the user's mouth, making it easier to clearly pick up the user's voice commands, while the speaker 4 is set at the bottom of the front shell 110 of the main unit, so that the speaker 4 is away from the user's mouth and nose area, reducing the risk of saliva or droplet contamination, and conforming to human usage habits; furthermore, the heat generated by the speaker 4 when it is working is quickly dissipated through the bottom of the casing 1, avoiding the problem of the microphone 8 set at the top of the front shell 110 of the main unit or the display 5 set in the middle of the front shell 110 of the main unit heating up, so that the structural layout is reasonable and compact.

[0092] In this embodiment, the host 10, for example, further includes a control circuit board 9. Specifically, the control circuit board 9 includes a first circuit board 91 and a second circuit board 92. The support frame 3 is provided with a support groove 301. The energy storage device 6, the first circuit board 91, and the second circuit board 92 are installed within the support groove 301. The extending direction of the first circuit board 91 intersects the extending direction of the second circuit board 92. The first circuit board 91 is located above the energy storage device 6 and is electrically connected to the energy storage device 6. The second circuit board 92 is disposed opposite to the display 5 and is electrically connected to both the display 5 and the first circuit board 91. Therefore, on the one hand, by installing the energy storage device 6, the first circuit board 91, and the second circuit board 92 within the support groove 301, the utilization rate of the three-dimensional space inside the housing 1 is improved, as well as the structural strength of the support frame 3 is enhanced. On the other hand, by placing the first circuit board 91 above the energy storage device 6 and electrically connecting it to the energy storage device 6, and by setting the second circuit board 92 opposite to the display 5 and electrically connecting it to the display 5 and the first circuit board 91, the connection lines between the first circuit board 91 and the second circuit board 92 are shortened, and the energy storage device 6 can supply power to functional devices such as the display 5, the first circuit board 91, and the second circuit board 92. Furthermore, since the extension directions of the first circuit board 91 and the second circuit board 92 intersect, it facilitates the placement of functional components on the first circuit board 91 and the second circuit board 92, reduces mutual inductance coupling and crosstalk, and facilitates the individual replacement or upgrading of the first circuit board 91 and the second circuit board 92. Of course, in some embodiments, the host 10 may include only one of the first circuit board 91 and the second circuit board 92; this embodiment of the present invention does not impose specific limitations.

[0093] Both the control module 1002 and the first communication module 1001 can be mounted on either the first circuit board 91 or the second circuit board 92. Exemplarily, in this embodiment, both the control module 1002 and the first communication module 1001 are mounted on the first circuit board 91. Therefore, since the control module 1002 and the first communication module 1001 are the electronic components with the highest power consumption in the host 10, mounting them both on the first circuit board 91 close to the energy storage device 6 shortens the power supply trace distance, reduces line impedance, avoids voltage drops, and ensures stable operation of the host 10 under high current demands.

[0094] The support frame 3 includes a base plate 31, a top plate 32, a back plate 33, and two side plates 34. The base plate 31, top plate 32, back plate 33, and two side plates 34 are fixedly connected and enclose a support groove 301. In this embodiment, the base plate 31, top plate 32, back plate 33, and two side plates 34 are integrally formed, thereby improving the reliability and stability of the connection between the base plate 31, top plate 32, back plate 33, and two side plates 34, and improving the assembly efficiency of the tongue and palpation diagnostic instrument 100. Of course, in some embodiments, at least two of the base plate 31, top plate 32, back plate 33, and two side plates 34 are detachably connected together by an installation structure. The connection method of the base plate 31, top plate 32, back plate 33, and two side plates 34 is not specifically limited in this embodiment of the present invention.

[0095] The bottom plate 31 is fixedly connected to the energy storage component 6 on the side facing the top plate 32. The top plate 32 is fixedly connected to the support frame 2 on the side facing away from the bottom plate 31. The back plate 33 is fixedly connected to the rear side of the bottom plate 31 and to the second circuit board 92. The two side walls are arranged opposite each other and fixedly connected to the bottom plate 31 and the back plate 33. The second circuit board 92 is fixedly connected between the two side plates 34. Specifically, each side plate 34 is provided with at least one bearing plate 341, and the second circuit board 92 is mounted on the bearing plate 341. Thus, based on the reasonable layout of the various functional components of the facial tongue diagnostic instrument 100 on the support frame 3, the overall compactness and rationality of the facial tongue diagnostic instrument 100 structure are improved.

[0096] The support plate 341 and the side plate 34 are integrally formed, thereby improving the connection reliability and stability between the support plate 341 and the side plate 34, as well as improving the assembly efficiency of the support plate 341 and the side plate 34. Specifically, the side plate 34 is provided with a cut edge, and the portion of the side plate 34 corresponding to the cut edge is flipped towards the support groove 301 to form the support plate 341. In some embodiments, the support plate 341 and the side plate 34 are independently arranged and fixedly connected.

[0097] Each side plate 34 can be trapezoidal or triangular in shape. For example, in this embodiment, the side plate 34 is approximately triangular in shape. The width of each side plate 34 gradually decreases from bottom to top in the arrangement direction from the image acquisition unit 50 to the host unit 10, thereby enhancing the overall structural strength of the support frame 3 and improving the anti-tipping ability of the image acquisition unit 50 when adjusting the pitch angle.

[0098] Please refer to the following: Figure 1 , Figure 11 and Figure 12 , Figure 11 yes Figure 2 A partial exploded view of the structure of the facial tongue diagnostic instrument 100 from a third-view perspective; Figure 12 yes Figure 5The image shows a cross-sectional view of the facial tongue diagnostic instrument 100 along the CC line. Exemplarily, in this embodiment, the bottom of the housing 1 is provided with a plurality of sound outlet holes 105 communicating with the receiving cavity 101. The speaker 4 includes a mounting shell 41, a speaker unit 42, and a sealing diaphragm 43. The mounting shell 41 is fixedly connected to the housing 1. The mounting shell 41 is provided with a mounting cavity 4101 and a sound outlet channel 4102. The sound outlet channel 4102 communicates with the mounting cavity 4101. The speaker unit 42 is disposed within the mounting cavity 4101. The sealing diaphragm 43 is adhered to the inner wall of the housing 1 and seals the plurality of sound outlet holes 105. Therefore, on the one hand, the sealing membrane 43 can prevent dust and moisture, thereby extending the service life of the speaker 4 and the electrical components of the facial and tongue diagnostic instrument 100. On the other hand, the sealing membrane 43 can prevent contaminants such as oral droplets and tongue coating from splashing into the sound outlet channel 4102, reducing the risk of microbial accumulation. On the other hand, the sealing membrane 43 can reduce the noise generated by the airflow directly impacting the diaphragm, improving the acoustic performance of the speaker 4.

[0099] In some embodiments, the loudspeaker 4 further includes a clamping member 44. The clamping member 44 abuts against the sealing diaphragm 43 and the mounting shell 41, and is used to press the sealing diaphragm 43 against the inner wall of the housing 1. The clamping member 44 is provided with a through hole 4401 communicating with the sound outlet channel 4102, and the clamping member 44 is configured as a rigid structure. Thus, on the one hand, by providing a clamping member 44 between the sealing diaphragm 43 and the mounting shell 41 to press the sealing diaphragm 43 against the inner wall of the housing 1, the problem of the sealing diaphragm 43 shifting or loosening relative to the housing 1 due to vibration or air pressure changes is avoided by directly attaching the sealing diaphragm 43 to the loudspeaker unit 42, thereby improving the sealing performance of the accommodating cavity 101 and increasing the flexibility of assembling the loudspeaker 4 with different housings 1; on the other hand, the through hole 4401 can serve as a sound wave guiding structure, and when the loudspeaker 4 is working, the loudspeaker unit The movement of the diaphragm of body 42 causes drastic changes in air pressure within mounting cavity 4101. The through hole 4401 of clamping member 44 allows air to flow slowly, preventing air pressure difference from hindering diaphragm movement. Additionally, air pressure is partially released through through hole 4401, reducing the pressure on sealing diaphragm 43 and extending its lifespan. Furthermore, clamping member 44 is made of rigid material, which also reinforces the structure of housing 1 corresponding to sound hole 105, preventing collision deformation. The through hole 4401 promotes air convection, helping to dissipate heat from the voice coil and magnetic circuit.

[0100] In this embodiment, the portion of the housing 1 corresponding to the sound outlet 105 is configured with an arc-shaped structure, thereby increasing the sound outlet area of ​​the sound outlet 105, improving the sound output effect of the speaker 4, and increasing the structural strength of the portion of the housing 1 corresponding to the sound outlet 105. The sealing diaphragm 43 is configured as an arc-shaped diaphragm. The clamping member 44 includes an abutting surface 4402 that abuts against the sealing diaphragm 43. The portion of the inner sidewall of the housing 1 corresponding to the sound outlet 105 and the abutting surface 4402 are both configured as arc-shaped surfaces. The curvature of the abutting surface 4402 is the same as the curvature of the portion of the inner sidewall of the housing 1 corresponding to the sound outlet 105 and the curvature of the arc-shaped diaphragm. On the one hand, the sealing diaphragm 43 is configured as an arc-shaped diaphragm, thereby improving the wall adhesion performance of the sealing diaphragm 43, improving the sealing performance of the accommodating cavity 101 and the mounting cavity 4101, improving the uniformity of sound wave diffusion of the speaker 4, improving the sound field performance, and enhancing the structural strength of the portion of the housing 1 corresponding to the multiple sound outlets 105. On the other hand, based on the configuration of the abutment surface 4402 as an arc-shaped surface, and the curvature of the abutment surface 4402 being the same as the curvature of the sealing diaphragm 43, the mechanical sealing performance between the sealing diaphragm 43 and the housing 1 is enhanced, and the pressure distribution of the sealing diaphragm 43 is made uniform. Furthermore, the arc-shaped structure itself has mechanical filtering characteristics, thereby improving the sound quality of the speaker 4. Of course, in some embodiments, the sealing diaphragm 43 is configured as a planar diaphragm or a wavy diaphragm, and this utility model embodiment does not specifically limit this. The shape of the sealing diaphragm 43 is adapted to the shape of the abutment surface 4402 and the shape of the housing 1 to achieve a sealed adhesion of the sealing diaphragm 43 to the inner wall of the housing 1.

[0101] In this embodiment, the sealing membrane 43, the clamping member 44, and the mounting shell 41 are independently arranged, and the clamping member 44 is sealed against the mounting shell 41 and the sealing membrane 43, thereby facilitating the assembly, maintenance, and replacement of the sealing membrane 43, the clamping member 44, and the mounting shell 41. The clamping member 44 includes a contact surface 4403 for contacting the mounting shell 41. The contact surface 4403 is arranged opposite to the abutment surface 4402 and is sealed against the end face of the mounting shell 41 facing the sealing membrane 43, thereby avoiding the problem of gaps between the clamping member 44 and the mounting shell 41 affecting the sound transmission effect.

[0102] Of course, in some embodiments, the clamping member 44 can also be sealed and fixedly connected to the mounting housing 41. For example, the clamping member 44 and the mounting housing 41 can be fixedly connected together by an adhesive layer, locking screws, etc., thereby avoiding the problem of gaps between the clamping member 44 and the mounting housing 41 affecting the sound transmission effect.

[0103] Please refer to the following: Figure 1 and Figures 11 to 13 , Figure 13 yes Figure 2The diagram shows a partial exploded view of the fourth-angle structure of the facial tongue diagnostic instrument 100. A limiting groove 106 is provided on the inner wall of the housing 1 corresponding to the area of ​​the multiple sound outlets 105. At least a portion of the sealing diaphragm 43 and the clamping member 44 are housed within the limiting groove 106, and the sealing diaphragm 43 is tightly and sealingly attached to the groove wall of the limiting groove 106. On the one hand, the limiting groove 106 improves the assembly yield and efficiency between the sealing diaphragm 43 and the clamping member 44 and the housing 1; on the other hand, the groove sidewall of the limiting groove 106 reduces the risk of displacement and loosening of the sealing diaphragm 43 relative to the housing 1 due to vibration or air pressure changes generated by the speaker unit 42 during operation, thus improving the sealing performance of the accommodating cavity 101.

[0104] In this embodiment, the speaker 4 is fixedly mounted on the housing 1. Specifically, the outer wall of the mounting housing 41 is provided with multiple connecting lugs 410. The housing 1 is provided with multiple fixing posts 113. The multiple fixing posts 113 are detachably fixedly connected to the multiple connecting lugs 410 respectively, and the sealing membrane 43 is pressed between the mounting housing 41 and the housing 1. Thus, on the one hand, the sealing membrane 43 is tightly attached to the housing 1 and the speaker unit 42 by the pressing force, thereby preventing moisture, dust and other foreign objects from entering the speaker 4, extending the service life of the speaker 4 and the internal electrical components of the face and tongue diagnostic instrument 100, and preventing sound leakage from the non-sound outlet area, ensuring directional sound wave output, and improving mid-low frequency response and sound clarity; on the other hand, compared with the sealing membrane 43 being fixed by adhesive or clips, the pressing force fixing method allows the sealing membrane 43 to withstand greater impact and vibration, prevent resonance, reduce distortion, and facilitate later maintenance or replacement of the speaker unit 42 and the sealing membrane 43. Of course, in some embodiments, the speaker 4 can also be fixedly mounted on the support frame 3; or, the speaker 4 can be fixedly mounted on both the support frame 3 and the housing 1.

[0105] In this embodiment, the number of speaker units 42 is set to multiple, and the mounting cavity 4101 includes multiple mounting chambers 4103, which are separated from each other and each of which is equipped with a multiple speaker unit 42. Therefore, by setting up mutually separated mounting chambers 4103, multiple sound-emitting components propagate in independent spaces, avoiding mutual interference of sound waves, reducing distortion and coloration, and improving the sound quality and effect of the speaker 4. Exemplarily, in this embodiment, the number of speaker units 42 and the number of mounting chambers 4103 are both set to two. Of course, in some embodiments, the number of speaker units 42 can also be set to one, and the number of mounting chambers 4103 can also be set to one. The number of speaker units 42 can be set according to actual conditions, and this embodiment of the present invention does not impose a specific limitation.

[0106] In some embodiments, the mounting cavity 4101 further includes a partition chamber 4104, with two adjacent mounting cavities 4103 isolated by the partition chamber 4104. Thus, by isolating the mounting cavities 4103 by the partition chamber 4104, on the one hand, the air layer within the partition chamber 4104 can absorb some vibration energy, reducing the resonance transmission of the mounting shell 41 and reducing sound coloration; on the other hand, the air layer within the partition chamber 4104 can also buffer the impact of external mechanical shocks on the precision unit; furthermore, the hollow partition chamber 4104 can promote air convection, preventing the heat from the high-power unit from affecting the tweeter magnetic circuit.

[0107] The mounting housing 41 includes a mounting base 411 and a mounting housing body 412. The mounting housing body 412 is fixedly connected to the mounting base 411 and encloses a mounting cavity 4101. The mounting base 411 and the mounting housing body 412 are arranged sequentially along the arrangement direction of the mounting housing 41 and the sealing membrane 43, thereby improving the reliability and stability of the sealing and pressure resistance between the mounting base 411 and the pressure-bearing component, and facilitating the assembly of the speaker 4 and the housing 1. Of course, in some embodiments, the mounting base 411 and the mounting housing body 412 can also be arranged sequentially along a direction perpendicular to the arrangement direction of the mounting housing 41 and the sealing membrane 43; this embodiment of the present invention does not impose a specific limitation. The mounting base 411 and the mounting housing body 412 are detachably fixedly connected together. This facilitates the assembly, disassembly, and maintenance of the internal structure of the speaker 4. For example, the mounting base 411 and the mounting housing body 412 can be detachably fixedly connected together by a snap-fit ​​structure, screw locking, magnetic adsorption structure, etc.

[0108] Please refer to the following: Figure 3 and Figure 14 , Figure 14 yes Figure 2The diagram shows a partial structural exploded view of the face and tongue diagnostic instrument 100 from a fifth perspective. In some embodiments, the face and tongue diagnostic instrument 100 further includes a support base 70. The support base 70 includes a base body 72 and a connecting frame 71. One end of the connecting frame 71 is connected to the host 10, and the other end of the connecting frame 71 is connected to the base body 72. The support base 70 is located at the end of the host 10 away from the image acquisition unit 50. The base body 72 is configured as a metal structure. The orthographic projection of the center of gravity of the host 10 in the height direction Z of the face and tongue diagnostic instrument 100 lies within the orthographic projection of the support base 70 in the height direction Z of the face and tongue diagnostic instrument 100. Therefore, on the one hand, the base body 72 is configured as a metal structure so that the mass distribution of the tongue diagnostic instrument 100 is shifted downward, thereby lowering the center of gravity of the tongue diagnostic instrument 100, reducing the risk of the tongue diagnostic instrument 100 tipping over, and improving the stability of the tongue diagnostic instrument 100 detection; on the other hand, based on the fact that the orthographic projection of the center of gravity of the host 10 in the height direction Z of the tongue diagnostic instrument 100 is located within the orthographic projection of the supporting base 70 in the height direction Z of the tongue diagnostic instrument 100, the torque generated by the gravity of the host 10 will be supported by the base 70. The reaction force of the supporting surface of the base 70 is offset, thereby preventing the face and tongue diagnostic instrument 100 from tipping over. On the other hand, the image acquisition unit 50 is rotatably connected to the top of the housing 1, thereby increasing the acquisition angle range of the image acquisition unit 50 and adapting to the shooting needs of different users. Furthermore, by placing the energy storage unit 6 and the speaker 4 at the bottom of the housing 1 and placing the image acquisition unit 50 at the top of the housing 1, the layout rationality of the face and tongue diagnostic instrument 100 is improved, and the anti-tipping ability of the image acquisition unit 50 is enhanced when adjusting the pitch angle.

[0109] The cross-sectional area of ​​the main unit 10 in the height direction Z perpendicular to the facial tongue diagnostic instrument 100 gradually decreases from the supporting base to the main unit 10. Therefore, the main unit 10 is designed to be narrower at the top and wider at the bottom, so that the bottom of the main unit 10 has a larger volume, which can concentrate more weight at the bottom and lower the overall center of gravity.

[0110] For example, in this embodiment, the main unit 10 is generally teardrop-shaped. Therefore, the near-circular bottom of the teardrop-shaped main unit 10 provides a uniform distribution of support force. When the image acquisition device 50 performs pitch movements, the friction between the bottom of the base body 72 and the support surface is more even, reducing the risk of tilting. Of course, in some embodiments, the main unit 10 can also be cone-shaped, but is not limited to, frustum-shaped, etc.

[0111] In some embodiments, the energy storage component 6 is disposed at the bottom of the housing 1. Therefore, by placing the energy storage component 6 at the bottom of the housing 1, the overall center of gravity of the main unit 10 is lowered, improving the anti-tipping ability of the main unit 10. It is understood that since the weight of the energy storage component 6 is relatively large compared to the weight of other functional components of the main unit 10, this embodiment of the invention places the center of the energy storage component 6 close to the center of gravity of the main unit 10, so that the mass distribution of the facial tongue diagnostic instrument 100 is shifted downwards, thereby lowering the center of gravity position of the facial tongue diagnostic instrument 100, reducing the risk of the facial tongue diagnostic instrument 100 tipping over, and improving the stability of the facial tongue diagnostic instrument 100's detection. In other words, the orthographic projection of the center of gravity of the main unit 10 in the height direction Z of the facial tongue diagnostic instrument 100 is located inside the orthographic projection of the energy storage component 6 in the height direction Z of the facial tongue diagnostic instrument 100.

[0112] The shape of the energy storage component 6 can be roughly rectangular or cylindrical. The regular shape of the energy storage component 6 allows it to fit more closely to the bottom contour of the main unit 10, optimizing space utilization and center of gravity concentration, and avoiding uneven weight distribution caused by irregularly shaped energy storage components 6.

[0113] For example, in this embodiment, the support frame 3 is configured as a metal structure, and the energy storage component 6 is mounted on the housing 1 through the support frame 3. Therefore, on the one hand, by configuring the housing 1 as a plastic structure and the support frame 3 as a metal structure, and by mounting the energy storage component 6 on the metal support frame 3, the facial tongue diagnostic instrument 100 is made lightweight. The housing 1 can also improve the structural design flexibility through injection molding, reducing the weight of the upper housing 1 while increasing structural strength. The housing 1 can also absorb the mechanical vibration generated by the host 10 during operation. On the other hand, the support frame 3 can improve the deformation resistance of the housing 1, and the rigid constraint of the support frame 3 can prevent the energy storage component 6 from shifting, maintain the initial center of gravity of the host 10, and reduce the risk of creep caused by the temperature generated by the energy storage component 6 during operation, preventing the energy storage component 6 from loosening. Furthermore, the support frame 3, as a metal sheet metal part, can serve as an auxiliary heat dissipation channel, conducting the heat generated by the energy storage component 6 during operation to the outside of the outer shell or the heat sink. The metal sheet metal part can be pre-installed with the energy storage component 6 before being assembled with the housing 1, realizing modular assembly and simplifying the production line process.

[0114] The display surface of the monitor 5 is set at an angle to the center of gravity of the main unit 10. In the projection plane perpendicular to the height direction Z of the facial and tongue diagnostic instrument 100, the center of the monitor 5 lies within the orthographic projection of the support base 70 onto the height direction Z of the facial and tongue diagnostic instrument 100. Therefore, on the one hand, when the center of the monitor 5 is within the projection range of the support base 70, the overturning moment generated by the weight of the monitor 5 is directly offset by the supporting force of the base, improving the anti-tipping ability of the facial and tongue diagnostic instrument 100 and reducing the overall center of gravity height of the main unit 10; on the other hand, it facilitates viewing the visual content displayed on the monitor 5 by users or medical personnel, enhancing the user experience of the facial and tongue diagnostic instrument 100.

[0115] The speaker 4 can be mounted on at least one of the housing 1 and the support frame 3. The speaker 4 and the energy storage unit 6 are laid flat on the bottom of the housing 1. Thus, on the one hand, when the speaker 4 is mounted on the plastic housing 1, the housing 1 can absorb the high-frequency resonance in the speaker 4, avoiding "metallic sound coloration" caused by metal, and avoiding the risk of short circuit caused by the magnetic circuit of the speaker 4 coming into contact with the metal support frame 3. When the speaker 4 is mounted on the support frame 3, local overload of the plastic housing 1 is avoided. On the other hand, the energy storage unit 6 and the speaker 4 are laid flat on the bottom of the housing 1, thereby lowering the overall center of gravity of the main unit 10 and improving the anti-tipping ability of the main unit 10.

[0116] Please refer to the following: Figure 2 , Figure 3 and Figures 14 to 17 , Figure 15 yes Figure 2 An exploded view of the first-angle diagram of the support base 70 of the facial tongue diagnostic instrument 100. Figure 16 yes Figure 2 An exploded view from a second perspective of the support base 70 of the facial tongue diagnostic instrument 100. Figure 17 yes Figure 6An enlarged view of part II of the facial tongue diagnostic instrument 100. In some embodiments, the connecting frame 71 includes a connecting shaft 711 and a connecting plate 712. One end of the connecting shaft 711 is fixedly connected to the housing 1. The other end of the connecting shaft 711 is fixedly connected to the connecting plate 712. The support base 70 includes a seat body 721, a first bearing member 73, and a second bearing member 74. The seat body 721 is provided with a first annular groove 7201, a second annular groove 7202, and a shaft hole 7203. The first annular groove 7201 and the second annular groove 7202 are respectively located at both ends of the seat body 721 in the height direction Z of the support base 70, and are connected through the shaft hole 7203. The first bearing member 73 is installed in the first annular groove 7201 and is located between the main unit 10 and the seat body 721. The second bearing member 74 is installed in the second annular groove 7202 and is located between the seat body 721 and the connecting plate 712. The connecting shaft 711 is rotatably inserted through the shaft hole 7203. Therefore, on the one hand, by rotatably mounting the connecting shaft 711 in the shaft hole 7203 provided in the base 721, and fixing the main unit 10 of the facial tongue diagnostic instrument 100 to the connecting shaft 711, the main unit 10 rotates relative to the base body 72 with the connecting shaft 711, so that medical staff and patients can use the facial tongue diagnostic instrument 100 in different positions, improving the operational flexibility of the facial tongue diagnostic instrument 100 and reducing the cleaning difficulty of the facial tongue diagnostic instrument 100; on the other hand, the first bearing member 73 and the second bearing member 74 are respectively provided at both ends of the base 721 to form symmetrical axial support, thereby dispersing the radial and axial loads when the main unit 10 rotates relative to the support base 70, reducing single-point stress concentration, and suppressing vibration or sway when the main unit 10 rotates, thus improving the stability of the main unit 10 rotation.

[0117] In this embodiment, the connecting shaft 711 and the connecting plate 712 are independently arranged and fixedly connected, thereby facilitating the assembly, maintenance, and replacement of the connecting shaft 711 and the connecting plate 712. Of course, in some embodiments, the connecting shaft 711 and the connecting plate 712 can also be integrally formed; this embodiment of the present invention does not impose specific limitations. The base body 72 is disposed between the connecting plate 712 and the housing 1, thereby restricting the movement of the base body 72 relative to the housing 1 in the height direction Z of the facial tongue diagnostic instrument 100, and restricting the movement of the base body 72 relative to the housing 1 in a plane perpendicular to the height direction Z of the facial tongue diagnostic instrument 100.

[0118] The bottom of the housing 1 is provided with a connecting hole 1301 communicating with the accommodating cavity 101. The support frame 3 is exposed at the connecting hole 1301, thereby facilitating the assembly of the connecting shaft 711 and the support frame 3. The connecting shaft 711 passes through the connecting hole 1301 and is fixedly connected to the support frame 3. Therefore, by fixing the connecting shaft 711 to the support frame 3, the reliability and stability of the fixed connection between the connecting frame 71 and the support frame 3 are improved, avoiding the problem that the reliability of the connection between the connecting frame 71 and the housing 1 would be reduced due to creep of the housing 1 if the connecting frame 71 is directly fixedly connected to the housing 1. This further improves the reliability and safety of the main unit 10 rotating relative to the support base 70. Exemplarily, in this embodiment, the bottom of the main unit's bottom housing 130 is provided with a connecting hole 1301 communicating with the accommodating cavity 101. In some embodiments, a flange 7111 extends radially from the end of the connecting shaft 711 facing away from the connecting plate 712. The flange 7111 is fixedly connected to the support frame 3.

[0119] In this embodiment, a grip portion 115 is provided on the housing 1. This grip portion 115 provides a gripping position for the user, facilitating the user's operation of the main unit 10 to rotate relative to the support base 70. The grip portion 115 is configured as a protruding structure provided on the edge of the front housing 110 of the main unit. Specifically, two protruding structures are provided on the two sides of the front housing 110 of the main unit to form two grip portions 115.

[0120] In some embodiments, the base body 72 further includes a bushing 75. The bushing 75 is installed within the shaft hole 7203. The connecting shaft 711 is rotatably inserted through the bushing 75. Thus, on the one hand, the bushing 75 avoids the problem of wear or scratches caused by direct contact between the connecting shaft 711 and the base body 72, extending the service life of the support base 70; on the other hand, the bushing 75 can also correct the machining error of the shaft hole 7203, improve the coaxiality of the bushing 75 and the connecting shaft 711, reduce the radial runout or wobble when the connecting shaft 711 drives the host 10 to rotate, provide uniform radial support, and avoid the problem of vibration or noise caused by uneven clearance when the connecting shaft 711 rotates.

[0121] In this embodiment, for example, the bushing 75 and the base body 72 are independently disposed. The bushing 75 is rotatably disposed within the shaft hole 7203. In some embodiments, the bushing 75 is fixedly connected to the base body 72. The bushing 75 is fixedly disposed within the shaft hole 7203. The bushing 75 can be fixedly connected by screw connection, interference fit, locking structure, or other means.

[0122] For example, in this embodiment, a support boss 722 is provided on the middle part of the base 721 near the main body 10. The support boss 722 has a stepped portion 7221 on the periphery of the shaft hole 7203. The bushing 75 includes a sleeve portion 751 and an overlapping portion 752, the overlapping portion 752 is connected to one end of the sleeve portion 751 in the axial direction and overlaps the stepped portion 7221. Therefore, on the one hand, the support boss 722 forms a thickened area in the middle of the base body 72, enhancing the bending and torsional stiffness of the base body 72 around the shaft hole 7203, avoiding stress concentration at the edge of the shaft hole 7203, and reducing the risk of deformation or cracking of the base body 72; on the other hand, the step portion 7221 provides a precise axial positioning reference for the bushing 75, preventing the bushing 75 from moving along the direction of the shaft hole 7203 during installation or operation, improving the coaxiality of the bushing 75 and the connecting shaft 711, and reducing radial runout or sway when the connecting shaft 711 drives the host 10 to rotate. Exemplarily, in this embodiment, the support boss 722 protrudes from the bottom wall of the first annular groove 7201.

[0123] The base body 72 has an extended protrusion 723 on the outer edge of the first annular groove 7201, and the main unit 10 has a mating groove 1302 that mates with the extended protrusion 723. Thus, on the one hand, the mating of the extended protrusion 723 and the mating groove 1302 forms a labyrinth-like sealing structure, preventing external dust and liquid from entering the first bearing area and extending bearing life; on the other hand, the mating of the extended protrusion 723 and the mating groove 1302 forms a physical alignment structure, guiding the main unit 10 and the support base 70 to quickly align during assembly, improving assembly efficiency and yield.

[0124] In some embodiments, the end face of the connecting plate 712 near the connecting shaft 711 is provided with a plurality of slots 7120 spaced apart along the circumferential direction of the connecting shaft 711. The base body 72 also includes an elastic snap-fit ​​member 78 disposed on the base body 721. The elastic snap-fit ​​member 78 engages with any one of the slots 7120 and can be detachably accommodated within the corresponding slot 7120. Thus, on the one hand, the plurality of slots 7120 are spaced apart along the circumferential direction of the connecting shaft 711, thereby allowing the relative angle or position between the connecting plate 712 and the base body 72 to be adjusted in stages to adapt to different angle requirements of the facial tongue diagnostic instrument 100; on the other hand, the elastic snap-fit ​​member 78 can be quickly snapped into any one of the slots 7120, and fixation can be completed without tools, improving the adjustment efficiency of the rotation of the main unit 10, and enabling the main unit 10 to be fixed relative to the base body 72 after rotating to a designated position, thereby improving the stability and reliability of the facial tongue diagnostic instrument 100.

[0125] The end face of the base 721 near the connecting plate 712 is provided with a receiving groove 7205. The elastic snap-fit ​​component 78 includes an elastic element 781 and a ball 782, with the elastic element 781 housed in the receiving groove 7205. The ball 782 snaps into the elastic element 781 and engages with the snap-fit ​​groove 7120. Therefore, on the one hand, the ball bearing 782, pushed by the elastic element 781, is engaged in different slots 7120, realizing multi-position angle or position adjustment of the connecting plate 712 and the base body 72. Furthermore, the ball bearing 782 can be disengaged from the slot 7120 with a slight rotation or translation of the connecting plate 712, allowing for quick adjustment without tools and improving the operating efficiency of the main unit 10. On the other hand, the elastic element 781 always applies radial pressure to the ball bearing 782, ensuring that the ball bearing 782 fits tightly with the slot 7120, eliminating assembly gaps and preventing the connecting plate 712 and the main unit 10 from shaking. Moreover, the ball bearing 782 produces a distinct "click" sound and feel when it is engaged in the slot 7120, indicating to the user that the adjustment is in place, avoiding misoperation, and improving the human-machine interaction effect.

[0126] Exemplarily, in this embodiment, a limiting boss 724 is provided in the middle of the base body 721 facing away from the host 10. Exemplarily, in this embodiment, the limiting boss 724 protrudes from the bottom wall of the second annular groove 7202. In other words, the second annular groove 7202 is arranged around the outside of the limiting boss 724. Thus, on the one hand, the limiting boss 724 forms a thickened area in the middle of the base body 72, enhancing the bending and torsional stiffness of the base body 72 around the shaft hole 7203, avoiding stress concentration at the edge of the shaft hole 7203, and reducing the risk of deformation or cracking of the base body 72. The bottom surface of the base body 721 facing away from the host 10 is higher than the end face of the limiting boss 724 facing away from the base body 721, thereby realizing that the connecting plate 712 is housed in the recess 7204, which is simple and compact. The housing groove 7205 is provided on the limiting boss 724, thereby reducing the risk of deformation or cracking of the base body 72.

[0127] The support base 70 also includes at least one first washer 76 and / or at least one second washer 77. The first washer 76 is disposed between the first bearing member 73 and the main unit 10 and / or between the first bearing member 73 and the seat 721; the second washer 77 is disposed between the second bearing member 74 and the seat 721 and / or between the second bearing member 74 and the connecting plate 712. Thus, on the one hand, the thickness of the first washer 76 and the second washer 77 can be finely adjusted to adjust the axial installation clearance of the first bearing member 73 or the second bearing member 74, improving the pre-tightening state of the first bearing member 73 or the second bearing member 74 and reducing radial runout or sway when the connecting shaft 711 drives the main unit 10 to rotate; on the other hand, the first washer 76 and the second washer 77 make the axial force distribution of the first bearing member 73 or the second bearing member 74 more uniform, preventing local stress concentration from damaging the first bearing member 73 or the second bearing member 74, and reducing the wear of the first bearing member 73 or the second bearing member 74.

[0128] The first washer 76 and the second washer 77 can be configured as elastic structures. For example, the first washer 76 and the second washer 77 can be configured as, but are not limited to, plastic structures, nylon structures, resin structures, etc. Exemplarily, in this embodiment, the first washer 76 and the second washer 77 are configured as plastic structures. Therefore, the first washer 76 and the second washer 77 can absorb the axial installation clearance of the first bearing member 73 or the second bearing member 74 during minor deformation, improving the pre-tightening state of the first bearing member 73 or the second bearing member 74 and reducing radial runout or sway when the connecting shaft 711 drives the host 10 to rotate. Of course, the first washer 76 and the second washer 77 can also be configured as rigid structures. Rigid structures can be configured as, but are not limited to, stainless steel structures or high-carbon chromium bearing steel structures, etc., and this embodiment of the present invention does not impose specific limitations.

[0129] In some embodiments, the bottom of the base 721 is further provided with a recess 7204 communicating with the second annular groove 7202. The connecting plate 712 is housed within the recess 7204. The recess 7204 covers the second annular groove 7202, and the edge of the recess 7204 is located outside the outer edge of the second annular groove 7202. The second bearing member 74 abuts against the connecting plate 712. Thus, on the one hand, the connecting plate 712 is completely housed within the recess 7204, reducing external protrusions, making the bottom of the base flatter, saving installation space, and improving the aesthetics of the support base 70; on the other hand, the recess 7204 covers the second annular groove 7202, forming a physical barrier to prevent dust, liquids, etc., from directly intruding into the second bearing member 74, extending the service life of the second bearing member 74; furthermore, when the second bearing member 74 needs maintenance, the second bearing member 74 can be directly exposed simply by removing the connecting plate 712, without disassembling the entire base body 72, reducing maintenance costs.

[0130] In this embodiment, the first bearing member 73 and the second bearing member 74 are configured as thrust bearings. This configuration increases the bidirectional axial force transmitted to the main unit 10, extends the service life of the first bearing member 73 and the second bearing member 74, and provides strict axial constraint to prevent axial movement of the main unit 10 or the connecting plate 712 during operation, thus improving transmission accuracy. Of course, in some embodiments, the first bearing member 73 and the second bearing member 74 can also be configured as tapered roller bearings or angular contact ball bearings.

[0131] In some embodiments, the support base 70 further includes an anti-slip pad 79. The anti-slip pad 79 is disposed on the bottom of the base body 721 and located in the area of ​​the base body 721 outside the area corresponding to the second annular groove 7202. Thus, on the one hand, the anti-slip pad 79 increases the coefficient of friction, preventing the host 10 from rotating relative to the support base 70 or the base body 72 from displacing relative to the support platform due to external forces; on the other hand, it reduces or isolates the contact area between the base body 72 and the support platform, reduces scratches caused by friction, and improves the reliability and stability of the host 10 rotating relative to the support base 70.

[0132] The anti-slip pad 79 can be configured as, but is not limited to, a suction cup structure, a magnetic structure, or a plastic structure. For example, in this embodiment, the anti-slip pad 79 is configured as a plastic structure to increase the friction between the support base 70 and the support platform, preventing the tongue diagnostic instrument 100 from sliding and tipping over.

[0133] In this embodiment, the number of anti-slip pads 79 is set to multiple. These multiple anti-slip pads 79 are spaced apart along the circumferential direction of the shaft hole 7203, thereby improving the uniformity of force distribution on the bottom of the support base 70 and reducing the risk of slippage and overturning of the tongue-shaped diagnostic instrument 100. The anti-slip pads 79 are generally arc-shaped.

[0134] In some embodiments, the number of anti-slip pads 79 can also be configured to be one. The anti-slip element can be annular in shape, thereby improving the uniformity of force distribution on the bottom of the support base 70 and reducing the risk of slippage and overturning of the tongue diagnostic instrument 100.

[0135] In some embodiments, an anti-slip groove 7206 is provided at the bottom of the base body 72. An anti-slip pad 79 is housed within the anti-slip groove 7206. Specifically, the anti-slip groove 7206 is formed by an indentation in the bottom wall of the base body 721 facing away from the main unit 10. The depth of the anti-slip groove 7206 is equal to the thickness of the anti-slip pad 79 in the height direction Z of the face tongue diagnostic instrument 100, thereby preventing dust or other debris from the external environment from remaining in the gap between the support base 70 and the support platform, and increasing the contact area between the support base 70 and the support platform, reducing the risk of the face tongue diagnostic instrument 100 sliding and tipping over. Of course, in some embodiments, the depth of the anti-slip groove 7206 can also be greater than the thickness of the anti-slip pad 79 in the height direction Z of the face tongue diagnostic instrument 100; this embodiment of the present invention does not impose a specific limitation.

[0136] In some embodiments, the anti-slip pad 79 is disposed at the bottom edge of the base body 72 to prevent dust or other debris from the external environment from remaining in the gap between the support base 70 and the support platform.
