Description

Technical Field

[0001] This utility model relates to the field of camera technology, and in particular to a self-cleaning device for camera lenses. Background Technology

[0002] A camera lens self-cleaning device is a functional device integrated into a camera system. It automatically removes dust, dirt, water stains, oil, and other contaminants from the lens surface through physical, chemical, or electromechanical methods. The aim is to maintain the cleanliness and transparency of the lens, ensuring that the camera continuously outputs clear and stable images. It is widely used in security monitoring, vehicle cameras, drone aerial photography, smartphone cameras, and other fields, effectively reducing the frequency of manual maintenance and improving equipment efficiency and reliability.

[0003] When camera lens surfaces are contaminated with dust, water stains, oil, and other pollutants, traditional brush cleaning devices can clean the lens surface through mechanical contact. However, with continuous use, a large amount of dirt gradually adheres to and accumulates in the gaps between the brush fibers and within the structure. As the number of uses increases, the brush's cleaning ability significantly diminishes due to the contaminants it carries. This not only fails to effectively remove dirt from the lens surface but may also cause secondary contamination during the cleaning process, severely impacting the camera's image quality. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the prior art, the brush will accumulate dirt inside after multiple cleanings, resulting in a decrease in the cleaning effect of the brush, and to propose a self-cleaning device for camera lenses.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a camera lens self-cleaning device, comprising a camera lens body, a first mounting bracket fixedly installed below the camera lens body, a lens cleaning component provided at one end of the first mounting bracket, a brush self-cleaning component provided on one side of the lens cleaning component, the brush self-cleaning component comprising a second mounting bracket, a water mist cleaning component and a wind-powered drying component, the water mist cleaning component and the wind-powered drying component being fixedly installed on one side of the second mounting bracket.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figures 1-4As shown, this utility model provides a self-cleaning device for camera lenses, including a camera lens body 1. A first mounting bracket 2 is fixedly installed below the camera lens body 1. A lens cleaning component 3 is provided at one end of the first mounting bracket 2. A brush self-cleaning component 4 is provided on one side of the lens cleaning component 3. The brush self-cleaning component 4 includes a second mounting bracket 41, a water mist cleaning component 42, and a wind-powered drying component 43. The water mist cleaning component 42 and the wind-powered drying component 43 are fixedly installed on one side of the second mounting bracket 41. The lens cleaning component 3 includes a first electric push rod 31, a second electric push rod 32, a rotation drive component 33, and a brush body 34. The first electric push rod 31 is fixedly installed on one side of the first mounting bracket 2, and the drive end of the first electric push rod 31 is fixedly connected to the second electric push rod 32. On the outside, the drive end of the second electric push rod 32 is fixedly connected to one side of the rotary drive assembly 33. The drive end of the rotary drive assembly 33 is fixedly connected to one end of the brush body 34. The rotary drive assembly 33 includes a third mounting bracket 331 and a drive motor 332. The drive motor 332 is fixedly installed inside the third mounting bracket 331. The drive end of the drive motor 332 is fixedly connected to one end of the brush body 34. The water mist cleaning assembly 42 includes a water supply pipe 421 and several nozzles 422. Several nozzles 422 are fixedly connected to the outside of one end of the water supply pipe 421. The wind-powered drying assembly 43 includes an air outlet chamber 431 and an air supply pipe 432. One end of the air supply pipe 432 is fixedly connected to the input end of the air outlet chamber 431. The air outlet of the air outlet chamber 431 faces the brush body 34.

[0023] The specific settings and functions of this embodiment are described below. The first electric push rod 31 drives the second electric push rod 32 to move away from the camera lens body 1. Then, the second electric push rod 32 drives the rotation drive assembly 33 to rise until the brush body 34 is facing the camera lens body 1. The drive motor 332 drives one end of the brush body 34 to rotate around the center. At the same time, the first electric push rod 31 is reset, so that the brush body 34 fits against one side of the lens and rotates to clean its surface.

[0024] When the surface of the brush body 34 becomes soiled and requires a self-cleaning process, the system activates a high-pressure water jet cleaning mechanism. High-pressure water is directed through the water supply pipe 421 and sprayed from several nozzles 422 located at specific positions, rinsing the brush body 34 in an atomized spray pattern, achieving efficient stain removal and cleaning. After the cleaning process is completed, the system automatically switches to the drying process. High-pressure airflow is delivered through the air supply pipe 432 and sprayed out in a directional airflow from the air outlet of the air chamber 431, quickly evaporating the moisture on the surface of the brush body 34 and completing the drying process after washing. Through this closed-loop cleaning and drying process, the risk of secondary contamination is completely eliminated when the brush body 34 is subsequently used for lens cleaning, ensuring the efficiency and cleanliness of the cleaning operation.

[0025] Example 2: Figures 1-5 As shown, the self-cleaning device for camera lenses in this utility model includes a camera lens body 1. A first mounting bracket 2 is fixedly installed below the camera lens body 1. A lens cleaning component 3 is provided at one end of the first mounting bracket 2. A brush self-cleaning component 4 is provided on one side of the lens cleaning component 3. The brush self-cleaning component 4 includes a second mounting bracket 41, a water mist cleaning component 42, and a wind-powered drying component 43. The water mist cleaning component 42 and the wind-powered drying component 43 are fixedly installed on one side of the second mounting bracket 41. The lens cleaning component 3 includes a first electric push rod 31, a second electric push rod 32, a rotation drive component 33, and a brush body 34. The first electric push rod 31 is fixedly installed on one side of the first mounting bracket 2. The drive of the first electric push rod 31... The drive end of the brush body 34 is fixedly connected to the outside of the second electric push rod 32. The drive end of the second electric push rod 32 is fixedly connected to one side of the rotary drive assembly 33. The drive end of the rotary drive assembly 33 is fixedly connected to one end of the brush body 34. The rotary drive assembly 33 includes a third mounting bracket 331 and a drive motor 332. The drive motor 332 is fixedly installed inside the third mounting bracket 331. The drive end of the drive motor 332 is fixedly connected to one end of the brush body 34. A guide ring 333 is fixedly installed on one side of the third mounting bracket 331. A guide groove 334 is opened on one side of the guide ring 333. A guide rod 341 is fixedly connected to one side of the other end of the brush body 34. One end of the guide rod 341 is located inside the guide groove 334.

[0026] The overall effect of this embodiment is that when the drive motor 332 drives one end of the brush body 34 to rotate, the guide rod 341 at the other end of the brush body 34 moves inside the guide groove 334, constraining the rotation trajectory of the brush body 34. Through the cooperative design of the guide rod 341 and the guide groove 334, not only is the rotation trajectory of the brush body 34 precisely constrained, but the stability and reliability of the cleaning operation are also significantly improved. In actual operation, this structure can effectively reduce the radial runout and sway amplitude of the brush body 34 during high-speed rotation, maintaining a constant contact pressure and adhesion between the brush and the lens surface, thereby significantly improving the uniformity and precision of lens cleaning and avoiding cleaning blind spots or localized excessive wear caused by brush wobbling.

[0027] The device is used and works as follows: Electric push rod 31 drives electric push rod 32 to move away from camera lens body 1. Then, electric push rod 32 drives rotary drive assembly 33 to rise until brush body 34 is facing camera lens body 1. Drive motor 332 drives one end of brush body 34 to rotate around the center. At the same time, electric push rod 31 resets, so that brush body 34 fits against one side of the lens and rotates to clean its surface.

[0028] When the surface of the brush body 34 becomes dirty and requires a self-cleaning process, the system activates a high-pressure water jet cleaning mechanism. High-pressure water is directed through the water supply pipe 421 and sprayed from several nozzles 422 located at specific positions, rinsing the brush body 34 in an atomized spray pattern, achieving efficient stain removal and cleaning. After the cleaning process is completed, the system automatically switches to the drying process. High-pressure airflow is delivered through the air supply pipe 432 and sprayed out in a directional airflow from the air outlet of the air chamber 431, quickly evaporating the moisture on the surface of the brush body 34, completing the drying process after washing.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
