Problems solved by technology

[0002] During dental examination and treatment, the most commonly used instrument for doctors is the oral mirror, which is convenient for doctors to observe the inside of the patient's oral cavity. In the prior art, in order to adapt to different observations, most oral mirrors have a double mirror structure, and Different mirror concavities to meet the needs of different observation ranges; existing mouth mirrors will be treated with anti-fog coating on the surface of the mirror body to avoid fogging of the mirror surface during use, but with the wear and tear of the mouth mirror after repeated use , or used in an environment with excessive temperature difference, the mirror surface of the mouth mirror will still be fogged, which will affect the normal observation during use. To solve this problem, it is necessary to improve the existing mouth mirror to enhance its anti-fog performance

Embodiment 1

[0039] like figure 1 , 2 , 3, this embodiment includes a handle 1, a mirror frame 2, and a mirror body 3, wherein the mirror frame 2 is welded on the handle 1, and the mirror bodies 3 are two, and they are stacked and arranged in the mirror frame 2. The side edge is sealed and fixed on the inner side wall of the frame 2 by sealant, and it also contains:

[0040] The heating and anti-fogging piece 4, the heating and anti-fogging piece 4 is arranged in the handle 1, and after its end passes through the handle 1, it is arranged between the mirror bodies 3 on the front and rear sides;

[0041] A blow drying part 5, the blow drying part 5 is arranged in the mirror frame 2;

[0042] With the above design scheme, in use, the mirror body 3 is heated by heating the anti-fog element 4, so that the temperature of the mirror body 3 is raised to 40°C, thereby preventing the mirror body 3 from condensing on the surface of the mirror body 3 during the working process. Fog, when there is w...

Embodiment 2

[0044] like image 3 , 4 As shown, on the basis of the above-mentioned embodiment 1, the heating and anti-fog component 4 includes:

[0045] There are two heat-conducting boxes 4-1, and two of the heat-conducting boxes 4-1 are respectively welded on the walls on the opposite side of the mirror body 3 on the front and rear sides;

[0046] There are two guide tubes 4-2, which are respectively penetrated and fixed on the side plates of the heat conduction boxes 4-1 on the front and rear sides, and the other end of the guide tubes 4-2 is pierced. After passing through the side plate of the frame 2, it is placed on the handle 1;

[0047] A connecting pipe 4-3, the connecting pipe 4-3 is arranged between the heat conducting boxes 4-1 on the front and rear sides, and the front and rear ends of the connecting pipe 4-3 respectively pass through the heat conducting boxes 4 fixed on the front and rear sides. On the board of -1, the heat conduction boxes 4-1 on the front and rear sides...

Embodiment 3

[0050] like Figure 5 As shown, on the basis of the above-mentioned Embodiment 2, the heat conduction box 4-1 is provided with a deflector 6, and the deflector 6 is spirally wound around the port side of the connecting pipe 4-3 to guide the The side edge of the flow plate 6 is glued and fixed on the inner side wall of the heat conduction box 4-1;

[0051] With the above design scheme, after the warm water enters the heat conduction box 4-1, the water flow is guided by the deflector 6, and then the water flow travels in a spiral shape, and then the water flow covers and contacts the inner wall of the heat conduction box 4-1.

Abstract

The invention relates to the technical field of medical instruments in the department of stomatology, in particular to a double-sided antifogging odontoscope, a heating antifogging piece is arranged in a handle in a penetrating mode, the end of the heating antifogging piece penetrates through the handle and then is arranged between mirror bodies on the front side and the rear side, and a blowing drying piece is arranged in a mirror frame; on the basis that an existing mouth mirror structure is not changed, the heating structure and the ventilation structure are arranged between the two layers of mirror bodies in the mirror frame, then the mirror bodies can be preheated through the heating structure conveniently, the temperature of the mirror bodies is kept similar to that of a human body, the fogging speed is reduced, meanwhile, the ventilation structure is arranged, dry air can be blown out actively, and the fogging effect is improved. Therefore, air blowing and drying can be carried out when the mirror body fogs.

Description

technical field [0001] The invention relates to the technical field of dental medical instruments, in particular to a double-sided anti-fog mouth mirror. Background technique [0002] During the examination and treatment of stomatology, the most commonly used instrument by doctors is the oral mirror, which is convenient for doctors to observe the inside of the patient's oral cavity. Different mirror concave degrees to meet the needs of different observation ranges; the existing mouth mirror will be treated with anti-fog coating on the surface of the mirror body to prevent the mirror surface from fogging during use, but with the wear and tear of the mouth mirror after repeated use , or in an environment with a large temperature difference, the mirror surface of the mouth mirror will still be fogged, which affects the normal observation during use. To solve this problem, the existing mouth mirror needs to be improved to enhance its anti-fog performance. SUMMARY OF THE INVENT...
