New description: 【New technical field of the invention】 This new type is a kind of air-conducting lens barrel structure for single-focus photographic lens, which is mounted in the camera module to prevent the inside of the lens barrel or The accumulation of moisture inside the module reduces the overall optical quality and enhances the application level of the product. [Prior Art] • With the advancement of technology and the development of small lenses, today's mobile phones, PDAs, NBs or portable 3C products are becoming more and more popular. The conventional technology on the market, as shown in the figure, shows that the lens barrel (1〇) is formed with a light-transmitting hole (1 1) and a receiving groove (3), wherein the receiving groove (3) is Providing an optical lens set (20) for mounting and fixing, and combining the screw structure (12) of the lens barrel with the module holder (3 〇), wherein the module holder (3) 0) The infrared interrupting element (4 ◦)' is set in the middle group and combined with the photosensitive component - Lu (5 〇), the following problems are solved after the practical use of the conventional technology: , f technology is used in the lens barrel (i 〇 ) The optical lens is finely set (2 〇) to meet the silk demand. However, after the optical lens group (2 〇) is set to the lens barrel, the internal air is almost obliquely isolated, so that Wei changes in temperature. The accumulation of gas leads to a decrease in optical quality. At the same time, under the miniaturization, the difficulty in designing the exhaust structure of the carrier (30) increases with the reduction of space, so if the module has no exhaust. In the design, after the lens barrel is set in the module, the object side of the module is equipped with a lens barrel. The image side is equipped with an infrared ray interrupting element (4 〇), and the sense 5 M3187 32 Light, and pieces (5 〇 ) ′ At this time, the air inside the module is isolated, which will also cause the accumulation of moisture inside the module. [New content] The purpose of the first pass is to provide a single type of non-photographic lens with air-conducting light. It can improve the accumulation of moisture inside the lens and the module, thereby improving the whole. The new lens barrel has a light-transmissive hole near the side end to form a screw structure at the periphery of the outer wall of the lens barrel, a valley groove is formed on the inner wall of the lens barrel, and a venting groove is arranged at the inner wall of the lens barrel; The venting groove described above guides the moisture generated inside the lens barrel and the inside of the module to avoid the accumulation of water and gas, thereby reducing the optical quality of the lens and improving the application level of the product. Regarding the new type of the case, the techniques, means and other strengths used in the above-mentioned purposes are listed in the following examples and are detailed with the drawings. I believe that the new type of target and the other advantages of the case can be Explain a deep and specific understanding. [Embodiment] The first embodiment of the present invention is shown in Fig. 2 and Fig. 2a. The main system is applied to a single-focus mechanical lens. The lens structure includes: a mirror (10) system Formed and made of plastic material, and the distance from the object side end of the lens barrel (10) to the imaging surface height (X) is less than or equal to 8 legs 'in which the lens barrel (1 C)) Close to the object side opening S-transparent hole (1 1 ), 6, M318732, the light transmission hole C11) provides light from the object side into the optical system; at the periphery of the outer wall of the lens barrel (10) a threaded structure 2); a receiving groove (13) is formed on the inner wall of the lens barrel (1 〇), and a rectangular section is provided at the inner wall of the lens barrel (1 〇) from the image side end to the object side end a venting groove (14); an optical lens group (20) comprising a first lens (2 1), a second lens (2 2) and a fixing ring (23); a module socket (3) 0), a screw joint is formed in the direction of the lens barrel (1 〇). The structure (3 1 ) can be screwed together with the screw structure (12) of the lens barrel (12). To make the module seat (3 〇) can be combined with the lens barrel (worker); an infrared ray interrupting element (4 〇) is set in the module holder (3 〇); - photosensitive element group (50), The system includes a semiconductor photosensitive wafer (5 work) and a circuit substrate groove (5 2); when: == the inside of the cylinder (1〇) or the exhaust groove (14) of the exhaustion (13) Out of the water; : The structure of the 'confirmed to avoid the mirror guilty') the internal water vapor lying down to reduce the lens optics. When it was released, it also improved the product's complexity and improved overall optical quality. Various embodiments of the °° type are exemplified below, in order to clearly disclose the implementation and features: The second embodiment of the present invention _3 figure '3rd Α _ shows (this embodiment of the big 7 ' M318732 part of the structure The same as the first embodiment, only the differences are explained here; this embodiment is based on the lens barrel (10 A ) having a light transmission hole (丄丄A) near the object side end, and is located at the outer wall thereof. Chengcai-thread structure (丨2 A), and a groove (13 A) formed on the inner wall thereof, and a vent groove having a triangular cross section at the side of the inner wall adjacent to the image side (1 4 A); When the inside of the lens barrel (10A) or the inside of the module generates moisture, the exhaust groove (χ 4 A) of the image side of the receiving groove (1 3 A) can be used. The water vapor is introduced at the side of the object by the flooding end of the lens and the accommodating groove (丄3 A ), and the generated gap discharges the water vapor, so the above structure can surely avoid the problem of water vapor accumulation inside the lens. At the same time, it can reduce the difficulty of mold development and improve the stability of lens assembly. Referring to FIG. 4, the third embodiment of the present invention is different in the foregoing embodiment in that the inner wall of the lens barrel is formed with a receiving groove (13B) and a venting groove (14 • B), and the receiving groove (13) B) The inner wall is formed with at least one or more different size step grooves (1 3 1 B ), and the design of the step groove (丄3 work B) can be matched with the first lens (21B) of the same size. Two lenses (22B) and a fixed ring (2 3 B) are assembled. It is worth mentioning that the venting grooves (14, 14a, i4b) of the present invention can be made in various shapes, such as triangular, trapezoidal, curved, and spiral, in addition to the foregoing embodiments. 8 • M318732 In summary, the present invention is an air-conducting lens barrel structure for a single-focus photographic lens. The venting groove provided on the inner wall of the lens barrel makes the lens barrel and the optical lens unit integrated. The structure has the venting groove between the two to remove the internal moisture, so the "industrial availability" of the present invention should be undoubted, in addition, the technology disclosed in the embodiment of the present invention The feature has not been published in the publication before the application, nor has it been used publicly. It not only has the fact that the effect is improved as described above, but also has the additional effect of not being negligible. Therefore, the novelty and progress of the novel are All of them have complied with the patent laws and regulations, and have filed a new type of patent application in accordance with the law, and prayed for a patent.
