Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to a filter housing with self-cleaning function. Background Technology

[0002] In the field of filter technology, the filter housing, as a crucial structural component protecting internal electronic components, directly impacts the filter's stability and lifespan. Especially in complex operating environments, filter housings are frequently exposed to contaminants such as dust and particulate matter. These contaminants easily adhere to critical areas like ventilation openings or dust filters, leading to reduced heat dissipation efficiency and even affecting the filter's normal operation. Therefore, effectively maintaining the cleanliness of the filter housing has become a significant research focus in this field.

[0003] Existing technologies have introduced some solutions that attempt to reduce contaminant intrusion by improving the housing structure or adding protective devices. For example, some patents propose a filter housing design with a dust filter, reducing the possibility of dust entry through physical blocking. However, these designs still have significant shortcomings. First, the dust filter will become clogged with dust over long-term use, leading to a significant decrease in ventilation efficiency and requiring regular manual cleaning, increasing maintenance costs and workload. Second, existing housing designs typically lack active cleaning functions, failing to achieve automatic cleaning of the dust filter or other easily contaminated areas without disassembling the housing, thus failing to meet the requirements for efficient and convenient use. Furthermore, while some complex cleaning devices can achieve a certain degree of automation, they are often cumbersome in structure, have high manufacturing costs, and occupy a large amount of space, hindering practical application and promotion.

[0004] Therefore, developing a filter housing with self-cleaning capabilities, capable of automatically cleaning key components without manual intervention, while also being simple in structure, easy to operate, and cost-effective, has become a pressing technical challenge in the field of filter technology. This invention offers an innovative solution to this problem, aiming to improve the reliability and ease of maintenance of filter housings, and providing new ideas and directions for the development of related technologies. Utility Model Content

[0005] This invention addresses the problems of existing filter housings, such as easy dust accumulation, high maintenance costs, and insufficient reliability. To address these issues, the invention employs the following technical solution: a filter housing with self-cleaning function, comprising a base plate, mounting plate, protective cover, wiring port, buckle, return spring, dustproof mesh frame, dustproof mesh assembly, motor, output shaft, rotating frame, brush, support slide rod, and actuating rod. The self-cleaning function of the filter housing is achieved through specific structural design and connection methods.

[0006] This utility model provides a filter housing with a self-cleaning function, wherein: the protective cover covers the outside of the filter housing, serving to protect the internal components; its inner side is provided with a sliding groove to guide the movement of the dustproof mesh frame and ensure that the dustproof mesh frame is smooth and stable during opening and closing; the dustproof mesh frame is fixed to the protective cover by buckles, the buckle design ensuring that the dustproof mesh frame will not loosen when closed, and facilitating disassembly and replacement; furthermore, the return spring is installed in the sliding groove, and when the dustproof mesh frame is opened, the return spring automatically returns the dustproof mesh frame to its initial position through elastic force; the dustproof mesh assembly includes multiple dustproof meshes, and the multi-layer design further enhances the dustproof effect, making it suitable for various complex environments.

[0007] Furthermore, the motor is fixed inside the filter housing and connected to the rotating frame via an output shaft, driving the brush on the rotating frame to clean the dust filter. The brush maintains close contact with the surface of the dust filter, removing accumulated dust and impurities during the cleaning process. In particular, the support slide rod is fixed inside the filter housing to support the rotating frame and ensure its stability during rotation, preventing deviation. The support slide rod is made of high-strength material, capable of withstanding mechanical stress during long-term use, ensuring its stability and durability.

[0008] Furthermore, the lever is designed as a manually operated component, allowing users to control the opening and closing of the dustproof mesh frame for easy maintenance and repair. The wiring port is located on the outside of the filter housing, providing an electrical connection interface for easy connection with other devices or circuits. The wiring port adopts a standardized design, enabling quick electrical connection. In particular, the slide is designed as a precision guiding structure with a smooth inner wall to reduce friction and ensure smooth and stable opening and closing of the dustproof mesh frame.

[0009] Furthermore, the opening and closing process of the dustproof mesh frame is achieved through the cooperation of the buckle and the return spring. When the user needs to clean or replace the dustproof mesh, the dustproof mesh frame can be manually opened by using the lever, at which time the return spring is compressed. After cleaning is completed, the lever is released, and the return spring automatically returns the dustproof mesh frame to the closed state through its elastic force. The buckle plays a limiting role in this process, ensuring that the dustproof mesh frame will not loosen when closed.

[0010] Furthermore, the specific implementation of the motor-driven output shaft rotation is as follows: after the motor is powered on, it generates rotational power, which is transmitted to the rotating frame through the output shaft, driving the brush on the rotating frame to sweep along the surface of the dustproof net; during the sweeping process, the brush adheres to the surface of the dustproof net with a certain pressure to remove accumulated dust and impurities; in particular, the start and stop of the motor are realized through preset control logic, and the user can set the sweeping frequency and time according to actual needs.

[0011] Furthermore, the rotating frame is fixed inside the filter housing by a support slide rod. The two ends of the support slide rod are connected to the inner wall of the filter housing and the rotating frame, respectively, forming a stable support structure. The design of the support slide rod ensures that the rotating frame remains balanced during rotation, avoiding the impact of vibration or displacement on the cleaning effect. In particular, the material selection of the support slide rod has been calculated and optimized to ensure that it has sufficient strength and durability during long-term use.

[0012] Furthermore, the dustproof mesh assembly enhances the dustproof effect through a multi-layer design. Specifically, multiple layers of dustproof mesh are arranged sequentially, with the pore size of each layer decreasing progressively to form a graded filtration structure. The first layer of dustproof mesh is used to intercept larger dust particles, while subsequent layers gradually intercept smaller dust particles and impurities. In particular, the materials used in the dustproof mesh assembly undergo special treatment, resulting in high antistatic and corrosion resistance properties, enabling it to adapt to various complex environments.

[0013] Furthermore, the precision guiding structure of the slide is achieved in the following ways: the inner wall of the slide is precision machined to form a smooth guiding surface, reducing the frictional resistance when the dustproof mesh frame moves; the length and width of the slide are precisely calculated to ensure that the dustproof mesh frame will not get stuck or shift during opening and closing; in particular, the bottom of the slide is provided with an installation groove for fixing the return spring, ensuring that the return spring will not come out of the predetermined position during operation.

[0014] Furthermore, the manual operation function of the lever is achieved in the following way: one end of the lever is connected to the dustproof mesh frame, and the other end extends to the outside of the filter housing. The user can control the opening and closing of the dustproof mesh frame by pushing or pulling the lever. The length and shape of the lever have been optimized to ensure convenient operation and conform to ergonomic principles. In particular, a limit device is provided at the connection between the lever and the dustproof mesh frame to prevent the lever from leaving the predetermined position during operation.

[0015] In the above technical solution, the filter housing with self-cleaning function provided by this utility model has the following beneficial effects: by setting up a dustproof mesh assembly and a protective cover, the entry of dust and other impurities is effectively reduced, significantly improving the dustproof capability of the filter housing; through the motor-driven self-cleaning function, there is no need for frequent manual cleaning of the dustproof mesh, greatly reducing the maintenance frequency and cost; the self-cleaning function ensures the long-term stable operation of the filter housing in harsh environments, improving the overall reliability of the equipment; the components are compactly arranged and have clear functions, which facilitates installation, use and maintenance, and is suitable for various application scenarios; the filter housing is flexibly designed and can be widely used in industrial, communication, power and other fields to meet the usage needs in different environments.

[0016] In summary, this utility model, through innovative structural design and functional integration, overcomes the shortcomings of existing technologies and provides a brand-new solution for improving the performance of filter housings. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] This utility model provides a filter housing with self-cleaning function, combined with an attached... Figures 1 to 4 The implementation method is explained in detail. For example... Figure 1 As shown, the filter housing includes a base plate 1, a mounting plate 2, a protective cover 3, a wiring port 4, a buckle 5, a return spring 6, a dustproof mesh frame 7, a dustproof mesh assembly 8, a motor 9, an output shaft 10, a rotating frame 11, a brush 12, a support slide rod 13, and a toggle rod 14. These components, through a specific structural design and connection method, together constitute a filter housing with a self-cleaning function.

[0022] The base plate 1 serves as the fundamental component of the entire device, upon which the mounting plate 2 is fixed for connecting the filter housing to other external equipment or supports. A protective cover 3 covers the exterior of the filter housing, protecting the internal components. A sliding groove 31 is provided on the inner side of the protective cover 3 to guide the movement of the dustproof mesh frame 7, ensuring smooth and stable opening and closing. The inner wall of the sliding groove 31 is precision-machined, resulting in a smooth surface that significantly reduces frictional resistance during the movement of the dustproof mesh frame 7. The length and width of the sliding groove 31 are optimized to prevent jamming or displacement of the dustproof mesh frame 7 during opening and closing. A dedicated mounting slot is also provided at the bottom of the sliding groove 31 to fix the return spring 6, ensuring that the return spring 6 remains in a stable position during operation.

[0023] The dustproof mesh frame 7 is fixed to the protective cover 3 by clips 5. The design of the clips 5 ensures that the dustproof mesh frame 7 will not loosen when closed, and also facilitates user disassembly and replacement of the dustproof mesh assembly 8. A return spring 6 is installed in the slide groove 31. When the dustproof mesh frame 7 is opened, the return spring 6 automatically returns the dustproof mesh frame 7 to its initial position through elasticity. This design not only improves the convenience of operation but also enhances the automation level of the device. The dustproof mesh assembly 8 consists of multiple layers of dustproof mesh, with the pore size of each layer decreasing progressively, forming a graded filtration structure. The first layer of dustproof mesh is used to intercept larger dust particles, while subsequent layers progressively intercept smaller dust particles and impurities. The material of the dustproof mesh assembly 8 undergoes special treatment, possessing antistatic and corrosion-resistant properties, adapting to various complex environments, and extending its service life.

[0024] The motor 9 is fixed inside the filter housing and connected to the rotating frame 11 via the output shaft 10, driving the brush 12 on the rotating frame 11 to clean the dust filter assembly 8. The output shaft 10 and motor 9 employ a high-precision fit design to ensure the stability and reliability of rotational power transmission. The rotating frame 11 is fixed inside the filter housing via a support slide rod 13, with both ends of the support slide rod 13 connected to the inner wall of the filter housing and the rotating frame 11 respectively, forming a stable support structure. The support slide rod 13 is made of high-strength material and has been optimized through calculations to withstand mechanical stress during long-term use, preventing vibration or displacement from affecting the cleaning effect. The brush 12 is mounted on the rotating frame 11 and maintains close contact with the surface of the dust filter assembly 8, removing accumulated dust and impurities during cleaning. The pressure of the brush 12 is controlled by a preset adjustment mechanism to ensure that the cleaning process is both efficient and does not damage the dust filter assembly 8.

[0025] The toggle lever 14 is designed as a manually operated component, with one end connected to the dustproof mesh frame 7 and the other end extending to the outside of the filter housing. Users can control the opening and closing of the dustproof mesh frame 7 by pushing or pulling the toggle lever 14. The length and shape of the toggle lever 14 are optimized for ergonomics and ease of operation. A limit device is provided at the connection point between the toggle lever 14 and the dustproof mesh frame 7 to prevent the toggle lever 14 from disengaging from its predetermined position during operation. The wiring port 4 is located on the outside of the filter housing, providing an electrical connection interface for easy connection to other devices or circuits. The wiring port 4 adopts a standardized design, supporting rapid electrical connection and improving installation efficiency.

[0026] In actual operation, the filter housing works as follows: S1 When the filter housing is in normal working condition, the protective cover 3 covers the outside of the housing, and the dustproof mesh frame 7 is fixed to the protective cover 3 by the buckle 5, forming a closed structure that effectively blocks external dust and other impurities from entering the housing. S2 When it is necessary to clean or replace the dustproof mesh assembly 8, the user manually opens the dustproof mesh frame 7 by using the lever 14. At this time, the return spring 6 is compressed, and the dustproof mesh frame 7 moves smoothly along the slide groove 31 to the open position. S3 After the user completes the cleaning or replacement operation, the lever 14 is released, and the return spring 6 automatically returns the dustproof mesh frame 7 to the closed state through its elastic force. The buckle 5 acts as a limit during this process, ensuring that the dustproof mesh frame 7 will not loosen in the closed state.

[0027] When the self-cleaning function is activated (S4), the motor 9 generates rotational power after being powered on. This power is transmitted to the rotating frame 11 via the output shaft 10, causing the brush 12 on the rotating frame 11 to clean the surface of the dust filter assembly 8. The brush 12 adheres to the surface of the dust filter assembly 8 with a certain pressure, removing accumulated dust and impurities during the cleaning process. The cleaning frequency and time can be set through preset control logic to meet the usage needs in different environments. After cleaning (S5), the motor 9 stops running, the rotating frame 11 returns to its initial position, and the brush 12 stops moving, awaiting the next cleaning instruction.

[0028] The design of this filter housing fully considers various needs in practical application scenarios. For example, in industrial environments, traditional filter housings are prone to dust accumulation due to the presence of a large amount of dust and particulate matter in the air, leading to high maintenance costs and insufficient reliability. This invention, however, effectively reduces the entry of dust and other impurities by incorporating a multi-layered dustproof mesh assembly 8 and a protective cover 3, significantly improving the dustproof capability of the filter housing. Simultaneously, the self-cleaning function driven by the motor 9 eliminates the need for frequent manual cleaning of the dustproof mesh assembly 8, greatly reducing maintenance frequency and costs. Furthermore, the compact layout and clearly defined functions of each component facilitate installation, use, and maintenance, making it suitable for various application scenarios such as communication base stations and power equipment cabinets.

[0029] In summary, this utility model, through innovative structural design and functional integration, overcomes the shortcomings of existing technologies and provides a brand-new solution for improving the performance of filter housings.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
