[0012] Furthermore, a waterproof layer is provided at the location where the protective lens connects to the opening end of the housing.

[0013] Furthermore, the protective lens is fixed to the open end of the housing via the following structure:

[0014] The opening end of the housing is recessed inward to form an annular groove, and the protective lens is fixed in the annular groove.

[0015] Furthermore, a waterproof layer is provided on the bottom surface of the protective lens at the position corresponding to the annular slot.

[0016] Furthermore, a covering layer is provided between the bottom surface of the protective lens and the waterproof layer.

[0017] Furthermore, the lens of the camera abuts against the bottom surface of the protective lens via the light-shielding member through the following structure:

[0018] The light-shielding component includes a mounting portion and a channel portion; the mounting portion forms a mounting channel adapted to the lens; the channel portion forms the light channel; the mounting channel communicates with the light channel.

[0019] The mounting portion is fitted over the lens through the mounting channel; the end of the channel portion away from the mounting portion abuts against the bottom surface of the protective lens.

[0020] Furthermore, the light source is ring-shaped.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0034] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0035] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0036] like Figure 1 and Figure 3 As shown, Figure 1This is a schematic diagram of the first overall structure of the oral cavity detection device provided in the embodiments of this application; Figure 3 for Figure 1 A magnified cross-sectional diagram of the provided dental examination endoscope.

[0037] This application provides an oral examination mirror 10, which includes: a protective lens 11, a camera 12, a light shield 13, a light source 14, and a housing 15; the camera 12 includes a lens 121; the light shield 13 forms a light channel 1311; the protective lens 11 includes a surface and a bottom surface; and the housing 15 forms an opening end 151.

[0038] The protective lens 11 is fixed to the opening end 151 of the housing 15; the camera 12 and the light source 14 are respectively fixed inside the housing 15.

[0039] Among them, the protective lens 11 is used to protect the camera and light source and other components installed inside the housing, or it has anti-fog function by being treated with anti-fog, etc. The surface of the protective lens can also be provided with various protective layers as needed.

[0040] The light source 14 is used to provide supplemental lighting for image or video acquisition by the dental examination mirror, in order to help improve the imaging effect of the dental examination mirror.

[0041] Specifically, the protective lens 11 can be fixed to the opening end 151 of the housing 15 using various existing or future methods.

[0042] like Figure 3 As shown, in an optional embodiment, the above-mentioned "protective lens fixed to the opening end of the housing" can be achieved by the following structure:

[0043] The opening end 151 of the housing 15 is recessed inward to form an annular groove, and the protective lens 11 is fixed in the annular groove.

[0044] The embodiments of this application, by fixing the protective lens in the annular groove formed by the inward recess at the opening end of the housing, can help to more firmly fix the protective lens to the opening end of the housing.

[0045] Specifically, the camera and light source can be fixedly installed inside the housing using various existing or future methods. For example, one or more support components (such as the control circuit board of the dental endoscope) can be installed inside the housing to fix the camera and light source to preset positions on the control circuit board.

[0046] The lens 121 of the camera 12 abuts against the bottom surface of the protective lens 11 through the light shield 13, and the light channel 1311 of the light shield is set along the axis corresponding to the lens 121.

[0047] Specifically, the aforementioned "lens 121 of camera 12 abuts against the bottom surface of protective lens 11 via light-shielding member 13" can be implemented using various structural forms, which will be illustrated in later embodiments. By setting a light-shielding member between the lens and the protective lens, and with the light channel 1311 of the light-shielding member axially corresponding to the lens, while ensuring that the shooting light enters the lens through the light channel 1311, the reflected interference light generated by the protective lens other than the light-shielding member is blocked, thereby reducing interference to the image captured by the camera and improving the imaging effect.

[0048] It should be noted that the light-shielding component can be a flexible component (e.g., a soft rubber component) or a rigid component (e.g., a metal component) as needed. In a preferred embodiment, the light-shielding component is a flexible component, which helps to better achieve a tight fit between the light-shielding component and the lens and / or protective lens as described in the following embodiments.

[0049] The light source 14 is disposed on the periphery of the light-shielding member 13 (see attached figure) or on the first side (e.g.) Figure 3 As shown), and is located radially at the outermost periphery of the light-shielding member 13; wherein, the first side is the side of the light-shielding member 13 away from the protective lens 11. In a preferred embodiment, the light source 14 is disposed on the first side, that is, behind the light-shielding member 13, which can reduce the overall radial width of the detection lens and facilitate insertion into the oral cavity.

[0050] It should be noted that the light source can be any desired shape, such as a multi-point distributed point light source, a ring light source, a linear light source, or an arc. In a preferred embodiment, the light source 14 is a ring light source, which can emit uniform light from multiple directions, thus improving the imaging effect.

[0051] Specifically, the light shield can be of various shapes as needed, such as cylindrical or frustum-shaped. To ensure that the light shield does not block the light source in the axial direction, thereby avoiding the situation where the light source is blocked and cannot shine through the protective lens to the target object in the oral cavity to be tested, the light source 14 is located radially at the outermost periphery of the light shield 13.

[0052] In this embodiment, the light source 14 is designed to be located radially at the outermost periphery of the light shield 13, which prevents the light shield from blocking the light source axially.

[0053] This application embodiment provides a light-shielding component between the lens and the protective lens, with the light channel of the light-shielding component positioned axially corresponding to the lens. This ensures that the shooting light enters the lens through the light channel while blocking reflected interference light generated by the protective lens outside the light-shielding component, thereby reducing interference to the image captured by the camera and improving the imaging effect.

[0054] Continue as Figure 3As shown, in an optional embodiment, the diameter of the light channel 1311 of the light shield 13 gradually increases along the direction from the camera 12 to the protective lens 11 (for example, the light channel 1311 can be truncated cone in shape).

[0055] In this embodiment, the diameter of the light channel 1311 of the light shield gradually increases along the direction from the camera to the protective lens, thereby expanding the shooting angle of the camera and satisfying the preset shooting angle range of the camera.

[0056] In an optional embodiment, the light-shielding member 13 and the lens 121 are in a tight fit without gaps.

[0057] The embodiments of this application design a tight fit between the light-shielding component and the lens without any gaps, which can prevent interfering light from entering the lens through the gap between the two.

[0058] In an optional embodiment, the light-shielding member 13 and the bottom surface of the protective lens 11 are in a tight fit.

[0059] In this embodiment, the light-shielding member and the bottom surface of the protective lens are tightly fitted together, which prevents interfering light from entering the lens through the gap between them.

[0060] Continue as Figure 3 As shown, in an optional embodiment, a waterproof layer 16 is provided at the location where the protective lens 11 connects to the open end of the housing 15.

[0061] It should be noted that regardless of the method of fixing the protective lens to the housing, there will often be a certain gap at the connection between the protective lens and the opening end. Since the protective lens often comes into contact with the inside of the oral cavity or is used for cleaning and disinfection, various liquids may flow into the interior of the oral examination endoscope through the gap. Therefore, setting a waterproof layer at the connection can prevent various liquids from entering the interior of the oral examination endoscope and reduce the risk of damage to the internal components of the oral examination endoscope.

[0062] Specifically, the waterproof layer can be formed using various existing or future waterproof materials, such as waterproof adhesives and double-sided tape.

[0063] Continue as Figure 3 As shown, in an optional embodiment, based on the previous embodiment's description of "the opening end 151 of the housing 15 is recessed inward to form an annular groove, and the protective lens 11 is fixed in the annular groove", a waterproof layer 16 can be provided on the bottom surface of the protective lens 11 at the position corresponding to the annular groove.

[0064] This application embodiment provides a waterproof layer on the bottom surface of the protective lens at the position corresponding to the annular groove, that is, at the position where the protective lens connects to the opening end of the housing. This effectively prevents various liquids from flowing into the interior of the oral examination end through the gap between the protective lens and the opening end of the housing.

[0065] Furthermore, in an optional embodiment, a covering layer is provided between the bottom surface of the protective lens and the waterproof layer.

[0066] Specifically, the overlay can be any color and material as needed, for example, a black paint layer.

[0067] In this embodiment, since the protective lens is usually transparent, when a waterproof layer is provided on the bottom surface of the protective lens, the aesthetics of the protective lens are often affected when viewed from the front. Therefore, by providing a covering layer between the bottom surface of the protective lens and the waterproof layer, the aesthetics can be enhanced.

[0068] Continue as Figure 3 As shown, in an optional embodiment, the above-mentioned "the camera lens abuts against the bottom surface of the protective lens through a light-shielding member" can be achieved by the following structure:

[0069] The light-shielding member 13 includes a mounting portion 131 and a channel portion 132; the mounting portion forms a mounting channel adapted to the lens 121; the channel portion 132 forms the aforementioned light channel 1311; the mounting channel communicates with the light channel 1311.

[0070] Mounting part 131 is fitted over lens 121 via mounting channel; the end of channel part 132 away from mounting part abuts against the bottom surface of protective lens 11.

[0071] In this embodiment, the mounting part 131 is sleeved on the outside of the lens 121 through the mounting channel; the end of the channel part 132 away from the mounting part abuts against the bottom surface of the protective lens 11. The light-shielding member can protect the lens with light through a simple structure, and the beneficial effect of improving the imaging effect is achieved with a low improvement cost.

[0072] like Figure 2 As shown, Figure 2 This is a schematic diagram of the second overall structure of the oral cavity detection device provided in the embodiments of this application.

[0073] In an optional embodiment, a removable protective cover 17 is provided on the exterior of the housing 15.

[0074] This application provides better protection for the dental examination mirror by incorporating a protective cover.

[0075] Continue as Figure 1As shown in Figure 2, based on the oral examination mirror 10 described in the previous embodiment, this application embodiment also provides an oral examination device, which includes the oral examination mirror 10 described in the above embodiment.

[0076] This application embodiment provides a light-shielding component between the lens and the protective lens, with the light channel of the light-shielding component positioned axially corresponding to the lens. This ensures that the shooting light enters the lens through the light channel while blocking reflected interference light generated by the protective lens outside the light-shielding component, thereby reducing interference to the image captured by the camera and improving the imaging effect.

[0077] Continue as Figure 1 As shown in Figure 2, in an optional embodiment, the oral cavity detection device further includes a handle 20; one end of the housing 15 away from the opening end is fixedly connected to one end of the handle 20.

[0078] Typically, the handle includes a handle housing with an internal handle receiving cavity for easy gripping by the doctor. The power supply, control circuitry, etc., can be located inside the handle, or both can be located in the internal space that connects the handle housing and the housing of the oral examination mirror.

[0079] Obviously, the embodiments described above are only some embodiments of this application, not all embodiments.
