As shown in fig. 5, the inner lens 10 in the present embodiment includes an inner lens sheet 11 and a single inner lens capturing structure 12, which is a detailed schematic view of an inner lens according to an embodiment of the present utility model. Wherein the inner lens sheet 11 is a black and transparent two-shot structure, the inner lens sheet 11 can be divided into two parts including an inner lens black sheet 111 and an inner lens transparent sheet 112. In this embodiment, the inner lens transparent sheet 112 has two, and the light guide 30 is located below the inner lens transparent sheet 112; the inner lens black sheet 111 serves as a fixing bracket for fixing the inner lens transparent sheet 112, and its 1 is located at both sides of the inner lens transparent sheet 112. Two inner lens transparent sheets 112 are integrally injection-molded with the inner lens black sheet 111. In this embodiment, there is only a single inner lens grabbing structure 12, and the single inner lens grabbing structure 12 is located on one side of the inner lens transparent sheet 112, and the other side of the inner lens transparent sheet 112 is not provided with the inner lens grabbing structure 12, so that the inner lens grabbing structure is in a concave shape. Standing in front of the head, the inner lens grasping structure 12 is located above the viewing angle of the human eye, and the inner lens grasping structure 12 can prevent the problem of forming the mucous membrane of the inner lens grinder.
The inner lens transparent sheet 112 side where the inner lens grasping structure 12 is not provided, and the joint between the inner lens transparent sheet 112 and the inner lens black sheet 111 has a mounting groove 113.
As shown in fig. 3, the structure of the light guide holder and inner lens 10 according to a preferred embodiment of the present utility model is shown schematically, and the light guide holder 20 and inner lens 10 according to the present embodiment includes the inner lens 10, as well as the light guide holder 20 and the light guide 30. The light guide 30 is fixed to the light guide holder 20, and the inner lens 10 and the light guide holder 20 are fitted to each other as described above. In the present preferred embodiment, the inner lens 10 is mounted over the light guide support 20. The light guide holder 20 includes a first side wall extension 21, a second side wall extension 22 disposed opposite to the first side wall extension 21, and a light guide support 23 connected between the first side wall extension 21 and the second side wall extension 22, wherein the first side wall extension 21, the second side wall extension 22, and the light guide support 23 enclose a light guide receiving groove 24, and the light guide 30 is fixed in the light guide receiving groove 24.
The first and second sidewall extensions 21 and 22 are located on both sides of the light guide 30, respectively.
The first sidewall extension 21 is located on a symmetrical side of the single inner lens capturing structure 12 in a symmetrical relationship with the single inner lens capturing structure 12. The first sidewall extension part 21 extends from the light guide support 20 toward the inner lens transparent sheet 112, and the first sidewall extension part 21 extends to the mounting groove 113 of the inner lens transparent sheet 112, so that the first sidewall extension part 21 is arranged in parallel with the inner lens black sheet 111, and can shield the inner lens black sheet 111, and the end part of the first sidewall extension part 21 extends to a position spaced from the lower part of the inner lens transparent sheet 112 by 0.5-1 mm. The second sidewall extension 22 extends to be disposed proximate to the inner lens capturing structure 12.
After the light guide 30 is lighted, light is emitted, and reflected to the inner lens black sheet 111 and the inner lens transparent sheet 112 by diffuse reflection of the light guide holder 20. When the mating structure of the light guide holder 20 and the inner lens 10 is viewed from the x-direction as shown in the figure, the side wall extension 21 shields the inner lens black sheet 111, so that the light reflected by the inner lens black sheet 111 cannot be seen from the x-direction, and therefore, a large black edge is not observed from the x-direction at the light boundary, and uniform light is observed.
Whereas in the prior art the inner lens 10 is not structured like in the present utility model the inner lens 10 comprises only a single inner lens gripping structure 12 comprising two inner lens gripping structures 12. None of the sides of the prior art inner lens transparency 112 is of concave design, with both sides being inner lens gripping structures 12. Since the inner lens transparent sheet 112 has the inner lens grabbing structure 12 on both sides, the first side wall extension 21 in the light guide support 20 cannot extend from the light guide support 20 to the mounting recess 113 of the inner lens transparent sheet 112, that is, the side wall extension 21 cannot cover the inner lens black sheet 111. The inner lens grabbing structure 12 is transparent and injection molded like the inner lens transparent sheet 112, and when viewed from the x direction, since there is no shielding of the first side wall extension portion 21, the inner lens black sheet 111 can be directly observed through the transparent and injection molded inner lens grabbing structure 12, which will result in that a larger black edge can be observed on the light boundary, and the light observed by the inner lens grabbing structure is uneven.
In another preferred embodiment, a single inner lens gripping structure 12 is integrally formed with the inner lens transparent sheet 112. In yet another preferred embodiment, the light guide 30 is in parallel relation to the inner lens transparent sheet 112, the light guide holder 20 is generally white, and light rays emitted by the light guide 30 reflect to appear as white light on the light guide holder 20. The light emitted from the light guide 30 is reflected by the first side wall extension 21 of the light guide holder 20 to form white light, and only white light is observed when viewed from the x direction, but the black edge formed by the inner lens black sheet 111 blocked by the first side wall extension 21 is not observed.
As shown in fig. 4, in accordance with another preferred embodiment of the present utility model, the light guide holder 20 is different from the inner lens black sheet 111 in the configuration of the inner lens, and the rest is as described above. In the present embodiment, the configuration of the light guide holder 20 and the inner lens black sheet 111 on the side of the first side wall extension 21 in the above-described embodiment is applied to the side of the single inner lens grasping structure 12. The configuration of the light guide holder 20 and the inner lens black sheet 111 on the side of the first side wall extension 21 in the above-described embodiment is adopted on the side of the single inner lens grasping structure 12, and still can be used in the present utility model, and the desired effects of the present utility model can be achieved. The relative configuration of the light guide support 20 and the inner lens black sheet 111 can be selected as desired, so long as the two cooperate with each other to ensure that the first sidewall extension 21 shields the inner lens black sheet 111.
As shown in fig. 6, which is a schematic view of the structure of the inner lens in a preferred embodiment of the present utility model, it can be seen that the inner lens has only a single inner lens gripping structure 12 in the overall structure.
As shown in fig. 7, a schematic view of a light guide structure in a preferred embodiment consistent with the present utility model is shown, in which the light guide 30 includes an LED light source and a circuit board. The LED light source is fixed on the circuit board, and the light emitting surface of the LED light source faces the light guide 30. After the LED light source is illuminated, the light is refracted through a light guide 30, such as an optical tip, and light is emitted. The LED light source may be replaced with other light sources as long as it can emit light by electric power.
