DETAILED DESCRIPTION

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which this invention pertains; the terms used in the specification of the application are intended only to describe specific embodiments and are not intended to limit this invention; the terms "including" and "having" and any variations thereof in the specification and claims of this invention and the accompanying drawings are intended to cover non-exclusive inclusions. The terms "first," "second," etc. in the specification and claims of this invention or the accompanying drawings are used to distinguish different objects, not to describe a specific order.

[0027] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] like Figure 1-4 The following are examples provided by the present invention.

[0030] The embodiment of the present utility model provides an oral examination mirror, comprising: a handle 10, a mirror box 20 and a reflector 30. The mirror box 20 is connected to the upper end of the handle 10, and the reflector 30 is installed at the front end of the mirror box 20. A push-pull mechanism 21 is provided in the mirror box 20, and a connecting seat 31 is provided on the back of the reflector 30. The push-pull mechanism 21 is connected to the connecting seat 31. The reflector 30 is a flexible mirror. The flexible mirror can be selected from existing products on the market that can be directly purchased. The push-pull mechanism 21 can be selected from a micro telescopic cylinder, a reciprocating gear mechanism or an inflatable airbag. The above products or mechanisms can also be directly purchased on the market. The telescopic end of the push-pull mechanism 21 can be extended and retracted back and forth to pull the reflector 30 inward or push it outward, thereby bringing The movable reflector 30 bulges outward or recesses inward from its center. Under normal conditions, the reflector 30 is a plane mirror. When the center of the reflector 30 bulges outward, the reflector 30 becomes a convex mirror. A convex mirror has the function of diverging light, which can expand the reflected field of view and help medical staff observe the oral condition in a wider range. When the center of the reflector 30 is recessed inward, the reflector 30 becomes a concave mirror. When the concave mirror is recessed to a certain degree, it has a magnifying effect, which helps medical staff observe some subtle details during oral examinations. After using the above-mentioned oral examination mirror, the push-pull mechanism 21 set in the mirror box 20 can push the flexible mirror 30 outward or pull it inward toward the center, thereby changing the shape of the reflective surface of the reflector 30, so that the reflector 30 has the effects of a plane mirror, a concave mirror, and a convex mirror. Medical staff can control the size of the mirror reflection image of the reflector 30 according to usage requirements to better observe the condition in the patient's oral cavity.

[0031] Furthermore, the mirror box 20 is bowl-shaped, and the mirror box 20 as a whole is relatively flat and smooth, and will not hinder insertion into the patient's mouth. The reflector 30 is arranged in the opening of the mirror box 20, so that a relatively closed cavity is formed in the mirror box 20. A sealing rubber ring 22 is flexibly connected between the outer edge of the reflector 30 and the inner edge of the opening of the mirror box 20, further improving the airtightness of the mirror box 20 and preventing water from entering or being contaminated in the mirror box 20. Another function of the sealing rubber ring 22 is that its flexible material can adapt to the deformation of the reflector 30, so that the reflector 30 will not fall off from the opening of the mirror box 20 in the deformed state, and can also always maintain good sealing during the deformation of the reflector 30.

[0032] Further, the connecting seat 31 is in the shape of a truncated cone and is arranged concentrically with the mirror 30, the end of the connecting seat 31 is provided with a ball head clamp jaw 32, the push-pull mechanism 21 is fixedly installed at the middle of the inner bottom wall of the mirror box 20, the telescopic end of the push-pull mechanism 21 is provided with a connecting ball head 23, the connecting ball head 23 is clamped with the ball head clamp jaw 32, which facilitates the installation and disassembly of the mirror 30. It can be understood that the inner end of the push-pull mechanism 21 is fixedly connected with the inner wall of the mirror box 20 or is fixed by screws, when installing the mirror 30, only need to install the mirror 30 in the opening of the mirror box 20, the connecting ball head 23 and the ball head clamp jaw 32 are automatically aligned, then press the mirror surface of the mirror 30 inward to make the connecting ball head 23 and the ball head clamp jaw 32 clamped, if it is necessary to disassemble the mirror 30, it is necessary to use a suction cup or other tools to pull the mirror 30 outward to separate the connecting ball head 23 and the ball head clamp jaw 32. It can be understood that the force required to separate the connecting ball head 23 and the ball head clamp jaw 32 is greater than the force required to pull the mirror 30 by the push-pull mechanism 21, so as to avoid the separation of the connecting ball head 23 and the ball head clamp jaw 32 in the normal use process.

[0033] Further, the front end of the mirror box 20 is provided with a plurality of illuminating lamp beads 24, the plurality of illuminating lamp beads 24 are uniformly distributed along the circumference of the mirror 30, which can illuminate during oral examination and facilitate medical staff to observe the situation in the oral cavity.

[0034] Further, the handle 10 includes a grip 11 and a telescopic rod 12, the telescopic rod 12 is movably connected with the grip 11, and medical staff can adjust the length of the handle 10 according to needs.

[0035] Specifically, the grip 11 is provided with a power supply 13 and a circuit board 14, the circuit board 14 is electrically connected with the power supply 13, the push-pull mechanism 21 and the illuminating lamp beads 24 respectively, it can be understood that the grip 11 and the telescopic rod 12 are both hollow structures, the connecting part of the telescopic rod 12 and the mirror box 20 is also provided with a wire hole, which facilitates the wire connection of the power supply 13, the circuit board 14, the push-pull mechanism 21 and the illuminating lamp beads 24.

[0036] Specifically, the angle between the grip 11 and the mirror surface of the mirror 30 is 120°-150°.

[0037] Specifically, the grip 11 is provided with a function button 15 and a charging interface 16, the function button 15 can be provided with a switch button and two control buttons, the two control buttons can control the pushing and pulling of the push-pull mechanism 21 respectively, and the charging interface 16 is used for charging the power supply 13.
