The mirror assembly includes a hollow liquid reservoir rod, a lens mounted at one end of the liquid reservoir rod, and a sealing connector. The liquid storage mirror rod has a liquid storage cavity inside for containing preheated liquid, and the sealing connection seat is threaded to the end of the liquid storage mirror rod away from the mirror and seals the liquid storage cavity; The sealing connection seat has a snap-fit ​​part at one end away from the liquid storage mirror rod, and the inner wall of the cylindrical mounting seat has a snap-fit ​​groove that matches the snap-fit ​​part. The mirror assembly is detachably snapped into the cylindrical mounting seat through the cooperation of the snap-fit ​​part and the snap-fit ​​groove.

2. The optical viewer with anti-fog and illumination functions according to claim 1, wherein, The adapter assembly is also provided with an illumination unit, which is disposed on the rotating part or the cylindrical mounting base, and the light emission direction of the illumination unit is towards the lens so that the light enters the oral cavity after being reflected by the lens; the handle assembly is provided with a power supply unit and a switch, and the power supply unit is electrically connected to the illumination unit.

3. The optical viewer with anti-fog and illumination functions according to claim 1, wherein, An angle locking mechanism is provided between the handle assembly and the adapter assembly; the rotating part is provided with a through hole coaxial with the shaft hole; the angle locking mechanism includes a fastening bolt that passes through the shaft hole and the through hole in sequence, and a locking handwheel that is threaded to the end of the fastening bolt; the rotation angle of the adapter assembly relative to the handle assembly is locked or released by tightening or loosening the locking handwheel.

4. The optical viewer with anti-fog and illumination functions according to claim 1, wherein, The snap-fit ​​structure between the cylindrical mounting base and the sealing connection base is a screw-fit structure; the snap-fit ​​groove is an L-shaped guide groove opened on the inner wall of the cylindrical mounting base; a guide block is protruding on the snap-fit ​​part, and the guide block can slide into the axial section of the L-shaped guide groove and then rotate along the circumferential section of the L-shaped guide groove to achieve locking.

5. The optical viewer with anti-fog and illumination functions according to claim 1, wherein, The liquid storage lens rod includes an integrally formed connecting section, a bent section, and a lens mounting section; the outer wall of the connecting section is provided with external threads, and the end of the sealing connecting seat facing the liquid storage lens rod is provided with an internal threaded cylinder, which is threadedly engaged with the connecting section for sealing; the bent section is connected between the connecting section and the lens mounting section, so that the lens mounting section and the connecting section form an angle of 120° to 140°.

6. The optical viewer with anti-fog and illumination functions according to claim 2, wherein, The handle assembly has a power slot at one end away from the ear bracket. A bottom cover is fixedly installed at the opening of the power slot. The power supply unit is a replaceable battery, which is placed inside the power slot.

7. The optical viewer with anti-fog and illumination functions according to claim 1, wherein, The liquid storage mirror rod is made of heat-insulating material. A heat-conducting component is provided between the lens mounting section and the lens. One side of the heat-conducting component is in contact with the liquid in the liquid storage cavity, and the other side is in contact with the lens to achieve directional heat transfer.

8. The optical viewer with anti-fog and illumination functions according to claim 1, wherein, The side of the lens facing away from the liquid reservoir rod is covered with a hydrophilic anti-fog coating.
