Embodiment Construction

[0026] The structure and effect of the present invention will now be described in detail with reference to the following embodiments in conjunction with the accompanying drawings.

[0027] like figure 1 , figure 2 As shown, it is a preferred embodiment of a lens module with rapid condensation and dissipation of the present invention: the lens module with rapid condensation and dissipation includes a lens barrel 1, a lens group 2, a socket 3, a limiter 4, A module holder 5 and a photosensitive member 6 . Two ends of the lens barrel 1 are provided with through holes 11 , 12 , and an accommodating space 13 therein. The two through holes 11 and 12 communicate with each other through the accommodating space 13 to define a light transmission path; the lens group 2 and the holder 3 are accommodated in the accommodating space 13 of the lens barrel 1, and the lens group 2 has a plurality of lenses 21-25 , wherein the lens 21 is the outermost outer lens, and the lenses 22-25 are oth...

Abstract

A dewing rapid dissipating lens module of the present invention comprises a lens cone, a lens group, a limiting member and a module base. A plurality of ventilation grooves are arranged in the lens cone, the module base is equipped with an accommodating chamber, and the lens group is equipped with at least two lenses, wherein one lens is equipped with a plurality of air discharge ducts at the periphery, and the air discharge ducts are distributed annularly and at intervals. The limiting member limits the lens group to be positioned at the lens cone, and the limiting member, one lens and the module base enclose the two ends of the lens cone separately to form an enclosed system in which the other lenses of the lens group are enclosed. A light path space is formed between the two lenses, so that the air discharge ducts are communicated with each other via the light path space, and the ventilation grooves are communicated with the air discharge ducts and the accommodating chamber, and accordingly, the accommodating chamber, the light path space, the air discharge ducts and the ventilation grooves jointly form an internal circulation channel for moisture dissipation.

Description

technical field [0001] The present invention relates to a lens module, in particular to a lens module with rapid condensation and dissipation. Background technique [0002] In order to be waterproof, the traditional lens module is sealed with glue between the lens and the lens or between the lens group and the lens barrel, so that the waterproof gas can escape. Although the external moisture is blocked, the moisture in the memory still remains, and in a high-humidity environment, the adhesive itself will absorb moisture, and the internal moisture will easily condense on the lens when there is nowhere to escape, which will affect the final image quality. . Some manufacturers also set up a ventilation groove on the inner wall of the lens barrel that communicates with the external atmosphere, so that the internal gas can escape to the outside; although this structure can discharge water vapor, the design of communicating with the external atmosphere can also easily bring in ex...
