Technical Field

[0001] This utility model relates to the field of filter technology, specifically a filter for ventilation openings. Background Technology

[0002] Ventilation filter screens are indispensable components in many fields such as modern building air conditioning systems, industrial plant ventilation, and electronic equipment heat dissipation. Their core function is to prevent impurities in the air from entering the system, thereby ensuring air quality, protecting the normal operation of equipment, and extending the system's lifespan.

[0003] Existing filters require regular cleaning, and the bolt-fixing method is extremely inconvenient. Maintenance personnel must use tools to unscrew each bolt one by one, which is a tedious and time-consuming process. This is especially true in situations where the installation space is narrow or frequent maintenance is required, which greatly increases the workload and time cost. To address this problem, the inventor designed a filter for ventilation openings. Utility Model Content

[0004] The purpose of this utility model is to provide a filter screen for ventilation openings, which has the advantages of simple structure, reasonable design, simple operation, saving time and effort, and greatly reducing the maintenance cost of daily cleaning or replacement of the filter screen, thus solving the problems mentioned in the above technical background.

[0019] Please see Figures 1 to 4 The present invention provides an embodiment of a filter screen for a ventilation opening, the filter screen including a support frame 1, a mounting component 2, a fixing pipe 3 and a filter element 4, the mounting component 2 being disposed inside the support frame 1, the fixing pipe 3 being disposed on one side of the mounting component 2, and the filter element 4 being disposed on the side away from the mounting component 2. Mounting component 2 includes mounting tube 21, bearing 22, connecting shaft 23 and threaded post 24; mounting tube 21 is fixed inside the support frame 1, bearing 22 is fixed inside the mounting tube 21, connecting shaft 23 is set in the inner ring of bearing 22, and threaded post 24 is fixed on the surface of one side of connecting shaft 23, and threaded post 24 is threadedly connected to the inside of fixing tube 3.

[0020] The support frame 1 is the mounting base for the entire filter screen. The fixing pipe 3 is the mechanical connection point between the filter element 4 and the support frame 1. The mounting pipe 21 is the fixed support for the mounting element 2. The bearing 22's core function is to allow the connecting shaft 23 to rotate very smoothly within its inner ring, while simultaneously bearing axial force, converting rotational motion into linear motion. The connecting shaft 23 is the transmission hub, converting rotational motion into linear displacement. The threaded column 24 locks or releases the filter element 4. A connecting plate 25 is fixed to the surface of the connecting shaft 23 away from the threaded post 24, and the connecting plate 25 is located inside the support frame 1.

[0021] The connecting plate 25 serves as the operating interface, facilitating the application of torque by the tools.

[0022] The connecting plate 25 has a guide groove 26 inside, which is in the shape of a cross.

[0023] The guide groove 26 can be operated using the most common Phillips screwdriver, which greatly improves the convenience and versatility of operation.

[0024] The filter element 4 includes a first fixing frame 41 and a second fixing frame 43, which are integrally formed. The height of the first fixing frame 41 is greater than the height of the second fixing frame 43. The surface of the fixing tube 3 is fixed to the surface of the first fixing frame 41. The first fixing frame 41 and the second fixing frame 43 are made of heat-resistant ABS resin.

[0025] The first fixed frame 41 and the second fixed frame 43 constitute the skeleton of the filter element 4.

[0026] A blade 42 is fixed on the surface of the first fixed frame 41 away from the connecting plate 25. The blade 42 is evenly distributed along the height direction of the first fixed frame 41 and is made of nylon fiber synthetic resin.

[0027] The core function of blade 42 is to intercept larger debris, such as plastic pieces, leaves, and flying insects.

[0028] The angle between the blade 42 and the first fixed frame 41 is 120 degrees.

[0029] The tilt angle design not only effectively guides airflow and intercepts debris, but more importantly, this tilt angle prevents debris from accumulating on the blades 42 and falling off, making it easier to remove debris under the action of airflow or when the filter screen is removed.

[0030] The filter plate 44 is fixed inside the second fixed frame 43, and the gap between the filter plates 44 is smaller than the distance between the blades 42.

[0031] Filter plate 44 is specifically designed to intercept finer particles, such as dust and lint.

[0032] Working principle: When it is necessary to disassemble or assemble the filter element 4, first insert the tool into the guide groove 26, then apply a rotational force to the connecting plate 25, causing the connecting shaft 23 to rotate inside the bearing 22, thereby causing the threaded column 24 to rotate, so that the threaded column 24 moves horizontally inside the fixed tube 3, causing the threaded column 24 to disengage from the fixed tube 3, thus separating the filter element 4 from the support frame 1. Then place the fixed tube 3 with the new filter element 4 outside the threaded column 24, and apply a rotational force to the connecting plate 25 again, so that the threaded column 24 rotates into the fixed tube 3.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
