Technical Field

[0001] This utility model relates to the field of camera component technology, and more specifically, to a camera lens anti-fog cover with a sealing structure. Background Technology

[0002] When a camera is used in cold winter, the internal temperature of the camera can get very high due to the large number of electronic components and lights inside. In cold weather, fog will form on the lens. In order to ensure the normal use of the camera, an anti-fog cover is usually added to the lens to protect it from fog.

[0003] However, some existing camera lenses and anti-fog covers have poor sealing, which causes fog to form inside the lens due to the temperature difference between the inside and outside of the camera when it is used in winter. This greatly affects the use of the camera and the quality of the footage.

[0004] Therefore, a camera lens anti-fog cover with a sealing structure is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a camera lens anti-fog cover with a sealing structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a camera lens anti-fog cover with a sealing structure, comprising an anti-fog base and a camera lens body. A second connecting piece is fixedly disposed on the outer wall of the camera lens body. A first connecting piece is movably disposed on the outer side of the camera lens body and below the second connecting piece. An anti-fog base is threadedly connected to the outer side of the first connecting piece. A sealing rubber ring is disposed on the surface of the second connecting piece that abuts against the first connecting piece. A third connecting piece is fixedly disposed on the inner wall of the anti-fog base. A sealing airbag ring is disposed on the inner wall of the anti-fog base and below the third connecting piece. A miniature air pump is installed on the outer wall of the anti-fog base. The miniature air pump and the sealing airbag ring are connected by a connecting hose.

[0007] Preferably, the top of the anti-fog seat has a through hole, and a transparent lens is installed inside the through hole at the top of the anti-fog seat.

[0022] Example 1

[0023] As attached Figures 1 to 5 The image shows a camera lens anti-fog cover with a sealing structure, including an anti-fog base 1 and a camera lens body 3. A second connecting piece 6 is fixedly disposed on the outer wall of the camera lens body 3. A first connecting piece 4 is movably disposed on the outer side of the camera lens body 3 and below the second connecting piece 6. The anti-fog base 1 is threadedly connected to the outer side of the first connecting piece 4. A sealing rubber ring 5 is disposed on the surface of the second connecting piece 6 that abuts against the first connecting piece 4. A third connecting piece 8 is fixedly disposed on the inner wall of the anti-fog base 1. A placement cavity 11 is formed inside the third connecting piece 8. Desiccant 12 is placed inside the 11. The dryer 12 is replaced by the staff according to the maintenance cycle. Several moisture suction holes 13 are opened on the third connecting piece 8. A sealing airbag ring 7 is set on the inner side wall of the anti-fog seat 1 and below the third connecting piece 8. A miniature air pump 9 is installed on the outer side wall of the anti-fog seat 1. The miniature air pump 9 and the sealing airbag ring 7 are connected by a connecting hose 10. An installation chamber 17 is fixedly set on the outer side wall of the anti-fog seat 1. A heat dissipation vent 18 is installed on the surface of the installation chamber 17. The installation chamber 17 covers the outside of the miniature air pump 9.

[0024] In operation, the miniature air pump 9 inputs gas into the sealing airbag ring 7 via the connecting hose 10, causing the sealing airbag ring 7 to inflate. The inflated sealing airbag ring 7 compresses the second connecting piece 6 and the third connecting piece 8 on both sides, improving the sealing performance between the anti-fog seat 1 and the camera lens body 3. Simultaneously, the compressed third connecting piece 8 causes the anti-fog seat 1 and the first connecting piece 4 threadedly connected to the anti-fog seat 1 to move upward. The upward-moving first connecting piece 4 further compresses the sealing rubber ring 5 on the bottom wall of the second connecting piece 6, thereby further improving the sealing performance between the anti-fog seat 1 and the camera lens body 3. This structure features a double sealing structure, which can improve the sealing performance between the anti-fog seat 1 and the camera lens body 3, thereby preventing water vapor from entering the camera lens body 3 and causing the lens on the camera lens body 3 to fog up from the inside, affecting the use of the camera and the image quality.

[0025] Example 2

[0026] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 5 As shown below, see details:

[0027] In a preferred embodiment, a through hole is provided at the top of the anti-fog seat 1, and a transparent lens 2 is installed in the through hole at the top of the anti-fog seat 1. An external thread is provided on the outer side of the first connecting piece 4, and an internal thread is provided on the inner side wall of one end of the anti-fog seat 1 to be threadedly connected to the first connecting piece 4. At the same time, a first magnetic suction ring 14 is provided in the second connecting piece 6, and a second magnetic suction ring 15 is provided in the first connecting piece 4 to be attracted to the first magnetic suction ring 14 on the second connecting piece 6. Several raised textures 16 are fixedly provided at equal intervals on the surface of the first connecting piece 4 away from the sealing rubber ring 5. The raised textures 16 are made of rubber. In use, the first connecting piece 4 can be rotated through the raised textures 16, and then the first connecting piece 4 is threadedly connected to the anti-fog seat 1 through the rotation, thereby completing the limiting and fixing between the first connecting piece 4 and the anti-fog seat 1.

[0028] In this embodiment, the miniature air pump 9 is a commercially available device known to those skilled in the art. It can be customized or selected according to actual needs. Here, we are only using it without making any structural or functional improvements, so we will not go into details here.

[0029] The working process of this utility model is as follows: First, the first connecting piece 4 can be rotated through the raised texture 16 on the first connecting piece 4. Then, the first connecting piece 4 is connected to the anti-fog seat 1 by the thread, thereby completing the limiting and fixing between the first connecting piece 4 and the anti-fog seat 1. Next, the micro air pump 9 inputs gas into the sealing airbag ring 7 through the connecting hose 10, which causes the sealing airbag ring 7 to bulge. The bulging sealing airbag ring 7 will squeeze the second connecting piece 6 and the third connecting piece 8 on the upper and lower sides, improving the sealing performance between the anti-fog seat 1 and the camera lens body 3. At the same time, the squeezed third connecting piece 8 will... The movable anti-fog seat 1 and the first connecting piece 4 threadedly connected to the anti-fog seat 1 move upwards. The upward-moving first connecting piece 4 further compresses the sealing rubber ring 5 set on the bottom wall of the second connecting piece 6, thereby further improving the sealing performance of the connection between the anti-fog seat 1 and the camera lens body 3. This structure has a double sealing structure, which can improve the sealing performance of the connection between the anti-fog seat 1 and the camera lens body 3, thereby preventing water vapor from entering the camera lens body 3 and causing the lens on the camera lens body 3 to fog up from the inside, affecting the use of the camera and the image quality. The above is the working principle of this kind of camera lens anti-fog cover with a sealing structure.
