Abstract
Description
Technical Field
[0001] This utility model relates to the technical field, specifically to a universal filter. Background Technology
[0002] Air filters are typically used in the intake system of internal combustion engines to filter the air entering the engine, removing dust, particulate matter, and other impurities, ensuring that clean air mixes with fuel for combustion and improving combustion efficiency.
[0003] Because different vehicles have different structures, the air filters are installed in different locations, resulting in different positions for the air filter's outlet and inlet. In order to be suitable for different vehicle models, different types of filters need to be manufactured, resulting in a large variety of filters and increasing manufacturing costs. Utility Model Content
[0004] This utility model addresses the existing technical problems by providing a universal filter.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A universal filter includes an upper shell and a lower shell. The upper shell is provided with an air inlet and an air outlet. The upper shell and the lower shell cooperate to form a filter chamber. A filter element is provided in the filter chamber. A conversion element is installed between the filter element and the upper shell.
[0006] Based on the above technical solution, the present invention can be further improved as follows:
[0007] Preferably, the filter element is a filter cartridge, and a plurality of filter cartridges are arranged along the height direction of the lower housing.
[0008] Preferably, the filter element is a cyclone filter tube, and the filter chamber is provided with an upper perforated plate and a lower perforated plate. The upper ends of the plurality of cyclone filter tubes are installed on the upper perforated plate and the lower ends are installed on the lower perforated plate. The conversion element is installed between the upper perforated plate and the upper housing.
[0009] Preferably, the upper housing has an air inlet chamber and an air outlet chamber, a partition is provided between the air inlet chamber and the air outlet chamber, the air inlet is connected to the air inlet chamber, the air outlet chamber is connected to the air outlet, the upper end of the conversion element is adapted to the upper housing, and the outer edge of the lower end is in sealed contact with the filter element.
[0010] Preferably, the conversion frame includes multiple ribs, and a hollow structure is provided between adjacent ribs.
[0011] Preferably, the middle part of the conversion frame is arched upwards.
[0012] Preferably, the conversion element is a conversion cover, which covers the upper end of the filter element. The conversion cover divides the filter cavity into an air inlet cavity and an air outlet cavity. The air inlet is connected to the air inlet cavity, and the air outlet is connected to the air outlet cavity.
[0013] Preferably, the upper end of the conversion cover is provided with an air outlet, which is adapted to the air outlet.
[0014] The beneficial effects of this invention are as follows: Air enters the filter chamber through the air inlet, where a filter element, such as a filter cartridge or a cyclone filter tube, filters the air. The filtered air is then discharged through the air outlet, ensuring effective air filtration. By setting a conversion element between the filter element and the upper housing, a suitable upper housing can be selected based on the vehicle structure, and a suitable filter element can be selected based on the upper housing. This allows the filter to adapt to the filtration needs of different vehicles without altering the structure of the filter element or the lower housing, improving the filter's versatility and flexibility, and reducing production and maintenance costs. Furthermore, the conversion element design makes installation and disassembly more convenient, improving work efficiency.
[0015] Furthermore, in practical applications, different vehicles or operating conditions may have different airflow requirements. By simply replacing the filter components, such as using different numbers of cyclone filter tubes or filter elements with different layers or thicknesses, the filter's flow capacity can be easily adjusted without replacing the entire filter unit. This not only reduces the number of filter sizes and lowers the cost, but also simplifies the maintenance and replacement process and improves operational convenience. Attached Figure Description

[0028] Example 1
[0029] like Figures 1 to 3As shown, this utility model discloses a universal filter, including an upper housing 10 and a lower housing 20. The upper housing 10 is provided with an air inlet 11 and an air outlet 12. The upper housing 10 and the lower housing 20 cooperate to form a filter chamber, and a filter element is provided in the filter chamber. The filter element is a plurality of cyclone tubes 30. The upper ends of the plurality of cyclone filter tubes 30 are installed on an upper perforated plate 40, and the lower ends are installed on a lower perforated plate 50. A conversion element is installed between the filter element and the upper housing 10. In this embodiment, the upper housing 10 is provided with an air inlet chamber and an air outlet chamber, and a partition 13 is provided between the air inlet chamber and the air outlet chamber. The air inlet 11 communicates with the air inlet chamber, and the air outlet chamber communicates with the air outlet 12. The upper end of the conversion element is adapted to the upper housing 10, and the lower end is adapted to the filter element. The conversion element is a conversion frame 60, which includes a plurality of protruding ribs, and a hollow structure is provided between adjacent protruding ribs. The upper end of the conversion frame 60 is adapted to the upper housing 10, and the outer edge of the lower end is in sealed contact with the filter element, preventing unfiltered air from being directly discharged from the air outlet 12 and ensuring the air filtration effect. Different conversion frames 60 can accommodate filter elements of different specifications and sizes, allowing upper housings 10 of different shapes to be assembled with filter elements of different flow rates or structures, improving the versatility of the filter, simplifying the filter assembly process, and reducing production costs. At the same time, the design of the conversion frame 60 allows air to flow more smoothly through the filter, reducing airflow resistance and improving the filter's filtration efficiency. Furthermore, the hollow structure between adjacent ribs increases the strength and rigidity of the conversion frame 60, preventing deformation or damage during operation and further extending the service life of the filter.
[0030] Furthermore, the middle part of the conversion frame 60 is arched upward, which further enhances the structural strength of the conversion frame 60, enabling it to remain stable even when subjected to large airflow pressure, and making it less prone to deformation or damage, thus enhancing its durability and stability.
[0031] In other optional embodiments, the filter element is a filter cartridge, which can be replaced according to different flow requirements to adapt to different working environments. Multiple filter cartridges are stacked along the height of the lower housing 20, giving the filter a larger filtration area, thereby improving the filter's filtration efficiency and effect. The arrangement of multiple filter cartridges allows the filter to have a larger dust holding capacity, extending its service life. Furthermore, arranging the filter cartridges along the height of the lower housing 20 ensures more uniform airflow as it passes through the filter, avoiding situations where localized airflow is too strong or too weak, further improving the filter's filtration efficiency.
[0032] Example 2
[0033] Reference Figures 4 to 7 As shown, the structure of the upper housing 10 and the conversion element differs from that of Embodiment 1.
[0034] In this embodiment, the filter element is a cyclone filter tube 30. The upper ends of multiple cyclone filter tubes 30 are mounted on the upper perforated plate 40, and the lower ends are mounted on the lower perforated plate 50. The conversion element is installed between the upper perforated plate 40 and the upper housing 10. The conversion element is a conversion cover 70, which covers the upper end of the filter element, that is, the conversion cover 70 covers the air outlet end of the cyclone filter tube 30. The conversion cover 70 divides the filter chamber into an air inlet chamber and an air outlet chamber. The air inlet 11 is connected to the air inlet chamber, and the air outlet 12 is connected to the air outlet chamber. Air enters the intake chamber through the intake port 11 and is then guided into the intake hole on the side of the cyclone filter tube 30. Under the action of the cyclone vanes of the cyclone filter tube 30, the air forms a vortex. Dust particles in the air are thrown towards the inner wall of the cyclone filter tube 30 under the action of centrifugal force and flow downward along the inner wall of the cyclone filter tube 30. Finally, they are discharged from the filter through the dust discharge hole at the lower end of the cyclone filter tube 30. The filtered clean air passes through the outlet end of the cyclone filter tube 30 and enters the outlet chamber, and then exits the filter through the outlet port 12 of the upper housing 10. The conversion cover 70 is tightly fitted with the upper perforated plate 40 and the upper housing 10, effectively guiding the flow direction of the air when passing through the cyclone filter tube 30. The clean air filtered by the cyclone filter tube 30 can smoothly enter the outlet chamber from its outlet end, avoiding any possible air leakage, thereby ensuring the overall filtration efficiency of the filter. In practical applications, users can select appropriate upper housing 10, conversion hood 70, and filter elements to assemble according to the specific needs of the vehicle or operating conditions, thereby meeting different filtration requirements. This design not only improves the versatility and flexibility of the filter but also reduces production and maintenance costs, bringing greater convenience and economic benefits to users.
[0035] Furthermore, the upper end of the conversion cover 70 is provided with an air outlet 71, which is adapted to the air outlet 12. Specifically, the outer wall of the air outlet 71 is tightly fitted with the inner wall of the air outlet 12 to prevent air leakage, improve the filtration efficiency of the filter, and improve the ease of assembly.
[0036] In summary, the universal filter provided by this utility model, through the ingenious design of conversion components such as the conversion frame 60 or conversion cover 70, enables the filter to meet the usage requirements of different vehicles or operating conditions. By using a filter element or cyclone filter tube 30 as the filter element, flexible adaptation to different operating conditions or flow requirements is achieved. Users can select the appropriate upper housing 10, conversion components, and filter elements to assemble according to the specific needs of the vehicle or operating condition to meet different filtration requirements. This not only improves the versatility and flexibility of the filter but also reduces production and maintenance costs, bringing more convenience and economic benefits to users.
[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
