Light and short, easy to carry, people want to be able to capture the image of the object on the mobile phone, and get a clear face, thus designing and manufacturing a digital camera module that can be easily installed in the mobile phone. The size of the mobile phone is relatively small, so the volume of the digital camera module installed in it is required to be higher, that is, the size of the digital camera module for the mobile phone needs to be smaller, thereby making the image quality of the body more The high requirement is that the image of the subject is still clear in volume reduction = ^1, and the image quality of the object depends to a large extent on the advantages and disadvantages of the optical components in the digital camera, such as lens and image sensing components. The conventional digital camera module usually includes a lens holder, a clock, a 'complex lens and an image sensing element, and the plurality of lenses are usually passed through the adhesive ◆ In the lens barrel' and between the lens and the lens, there is a two: between. However, in the high-humidity reliability of the camera lens module, due to the water absorption of the rubber material, or the small gap caused by the package, And 200817827 makes water vapor into the lens can no longer be dissipated, so that water vapor condenses on the surface of the lens, which reduces the transmittance of the lens, and seriously reduces the light reflected by the object in the digital camera module, thereby reducing the subject. The optical image signal makes the optical image signal sensed by the image sensing component incomplete, and reduces the imaging quality of the image captured by the digital camera. [Invention] In view of the above, it is necessary to provide a method for dispersing moisture and improving image quality. A camera module. It is also necessary to provide a lens module capable of dissipating moisture and improving image quality.

The light-passing aperture 520 is located at the center of the half-closed end of the lens barrel 52, from which external light can enter. The lens 54 is a spherical or aspherical lens for concentrating incident light onto the image sensing device 20 of the camera. The lens 54 includes an optical portion 541 and a base 543 which is located in the middle of the base 543. At least one first notch 545 is disposed at the edge of the lens 54. In this embodiment, six first notches 545 are spaced and evenly disposed, and the first notch 545 is an arcuate notch. In the present embodiment, the spacer is a spacer ring 56 which is a ring having an outer diameter equal to the outer diameter of the lens 54 and respectively equal to the inner diameter of the lens barrel 52. The spacer ring 56 has a light passing hole 561, upper and lower surfaces 563 and a side wall 565. At least one second notch 567 is disposed on the side wall 565 of the spacer ring 56. The number and position of the second notch 567 correspond to the first notch 545 distribution on the lens 54. The spacer ring 56 has a venting groove 58 corresponding to and communicating with the second notch 567, and the venting groove 58 penetrates the surface 563 in the radial direction of the spacer ring 56. The spacer ring 56 is disposed between the adjacently disposed lenses 54 and is received and held in the lens barrel 52 together with the 200817827 lens 54. When the lens 54 and the spacer ring 56 are received and held in the lens barrel 52, the first notch 545 formed in the lens 54 is placed corresponding to the second notch 567 formed in the spacer ring 56 and forms a channel, and the channel and the spacer ring 56 are formed. The upper venting groove 58 communicates to form an air passage so that moisture between adjacent lenses 54 can escape through the air passage. Obviously, the venting groove 58 of the spacer ring 56 can be replaced by a vent hole provided on the side wall 565 of the spacer ring 56. The vent hole is one or more through holes and is opposite to the first notch 545 and the second notch 567. Corresponding and connected. The venting groove 58 may also be disposed on the upper surface or the lower surface of the base 543 of the lens 54 and corresponding to and communicate with the first notch 545. Further, the venting groove 58 may alternatively be an air guiding tube disposed between the lens 54 and the spacer ring 56. The image sensing device 20 is fixed to the open end of the lens barrel 52 and is located on the image forming surface of the lens group constituted by the complex lens 54.

The gap 567 is such that moisture is dissipated from the passage formed by the first gap 545 and the second gap 567. It can be understood that the spacer rings 16, 56 can be replaced by a plurality of spacer blocks disposed between adjacent lenses 54, a channel defined between adjacent spacer blocks, and a groove 124 or a first notch 545 on the lens barrel 12 and The channels of the second notches 567 are connected to form an air passage from which moisture between adjacent lenses 14 or lenses 54 can escape. 11 200817827 In summary, the present invention complies with the requirements of the invention patent, and proposes a patent application according to law.
