Description
Technical Field
[0001] This utility model relates to the technical field of filter elements, and specifically discloses a filter element and filter with anti-vibration function. Background Technology
[0002] Filter elements are key components in various power equipment, ventilation systems, and fluid filtration devices, widely used in automobiles, industrial equipment, air purifiers, and other fields. Their main function is to filter dust, impurities, and particulate matter from the air, protecting the internal components of the equipment from wear and contamination, thereby ensuring normal operation and extending the equipment's lifespan. The performance of the filter element directly affects the operating efficiency and stability of the equipment; therefore, factors such as filtration efficiency, sealing performance, durability, and cost must be comprehensively considered during the design and manufacturing process.
[0003] However, most filter elements are currently installed and secured only by the outer casing or clips, without a dedicated vibration-damping structure. When equipment (such as car engines and industrial fans) vibrates during operation, the filter element is prone to collision and friction with the casing, leading to filter element damage and decreased sealing performance. In this case, not only is the filter element's lifespan shortened, but unfiltered impurities may also enter the equipment, affecting operational stability and increasing maintenance costs. Therefore, developing a filter element and filter with vibration-damping capabilities is a pressing issue in the current technological field. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a filter element and filter with anti-vibration function.
[0005] On the one hand, this utility model discloses a filter element with anti-vibration function, which adopts the following technical solution: A filter element with vibration damping function is installed in a filter housing and includes a filter element body, a frame, and a support member. The frame is used to fix the filter element body. The support member is arranged on the inflow side and / or outflow side of the filter element body. The end of the support member protruding from the surface of the filter element body is provided with a damping member, and the damping member contacts the inner wall of the filter housing.
[0006] Preferably, the filter element body is provided with support members on both the inflow side and the outflow side. The support members arranged on the inflow side and the outflow side of the filter element body are integral in the same axial direction. The support member includes a connecting section connected to the filter element body in the middle and support sections extending axially to both ends of the connecting section. The support sections at both ends protrude from the inflow side surface and the outflow side surface of the filter element body, respectively. Preferably, the end of the support member is provided with a groove, the damping member is provided with an insertion part, the insertion part is matched and inserted into the groove, and the outer diameter of the insertion part is interference-fitted with the groove.
[0007] Preferably, the support member is a hollow structure with an inner cavity, the bottom wall of the groove is provided with an exhaust hole communicating with the inner cavity, and the side wall of the inner cavity is provided with a through hole communicating with the outside.
[0008] Preferably, the support member is a hollow structure with an inner cavity, and the damping member is provided with an insertion part, which is matched and inserted into the opening of the inner cavity, and the outer diameter of the insertion part is interference-fitted with the opening of the inner cavity.
[0009] Preferably, the outer periphery of the insertion part is provided with an anti-detachment protrusion, and the anti-detachment protrusion is interference-fitted with the groove.
[0010] Preferably, the filter element body is provided with reinforcing ribs connected to the frame, and the support member is formed on the reinforcing ribs.
[0011] Preferably, the reinforcing ribs, supporting members, and frame are integrally formed.
[0012] Preferably, a sealing ring is provided on the outer side of the frame, and the sealing ring is in a sealing fit with the filter housing.
[0013] On the other hand, this utility model discloses a filter, which adopts the following technical solution: A filter includes a housing and the aforementioned vibration-damping filter element installed within the housing.
[0014] Compared with the prior art, the present invention has at least the following beneficial effects: This invention provides a support member on the inflow and / or outflow side of the filter element body, and equips the end of the support member with an elastic damping member. When the equipment vibrates, the damping member absorbs energy, reduces the collision between the filter element and the housing, avoids damage, and limits the displacement of the filter element. This maintains a tight fit between the filter element and the filter housing, ensuring installation sealing. This not only extends the life of the filter element, but also improves the stability and reliability of the filter in a vibration environment and optimizes filtration performance.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0018] Example 1 This embodiment discloses a filter element and filter with anti-vibration function. The filter includes a housing and the anti-vibration filter element installed inside the housing. (Refer to...) Figure 1-5 The filter element with vibration damping function includes a filter element body 1, a frame 2, and a support member 3. The frame 2 is used to fix the filter element body 1. A sealing ring 6 is provided on the outer side of the frame 2. The sealing ring 6 is sealed with the filter housing to ensure effective sealing of the filter element. The support member 3 is arranged on the inflow side and / or outflow side of the filter element body 1. A damping member 4 is provided at the end of the support member 3 that protrudes from the surface of the filter element body 1. The damping member 4 is made of an elastic material, specifically rubber, silicone, or thermoplastic elastomer, etc., which have good elasticity and durability. The damping member 4 is in contact with the inner wall of the filter housing. This solution provides a support member 3 on the inflow and / or outflow side of the filter element body 1, and equips the end of the support member 3 with a damping member 4 made of elastic material. Due to the elastic deformation and recovery of the damping member 4, when the equipment or engine vibrates, the damping member 4 can effectively absorb vibration energy, significantly reducing the collision and friction between the filter element and the filter housing. This not only avoids damage to the filter element caused by vibration, but also maintains the tight fit between the filter element and the housing sealing ring 6, ensuring the sealing of the filtration process, thereby extending the service life of the filter element and improving the operational stability and reliability of the filter in a vibration environment.
[0019] In this embodiment, support members 3 are provided on both the inflow and outflow sides of the filter element body 1. Preferably, the support members 3 arranged on the inflow and outflow sides of the filter element body 1 are designed as a single unit along the same axial direction. Each support member 3 includes a connecting section 301 connected to the filter element body 1 in the middle and support sections 302 extending axially from both ends of the connecting section 301. The two end support sections 302 protrude from the inflow and outflow surfaces of the filter element body 1, respectively. This design allows the support member 3 to act simultaneously on both the inflow and outflow sides of the filter element body 1, forming comprehensive vibration protection. On the one hand, the integral support member 3 enhances the stability and rigidity of the structure, ensuring that the filter element body 1 is not easily deformed or displaced under vibration. On the other hand, the coaxial design of the two end support sections of the support member can more evenly distribute vibration energy, reduce local stress concentration, and further improve the vibration resistance of the filter element body 1. Of course, in other embodiments, the support members 3 on the inflow side and outflow side of the filter element body 1 may not be integral in the same axial direction, but may be arranged separately and independently. Alternatively, only the inflow side of the filter element body 1 may have a support member 3, or only the outflow side of the filter element body 1 may have a support member 3.
[0020] As a preferred embodiment, the inner wall of the support section end of the support member 3 has a groove 31, and the lower part of the damping member 4 has an axially extending insertion part 41. The insertion part 41 is matched and inserted into the groove 31, and the outer diameter of the insertion part 41 is interference-fitted with the groove 31. By snapping the insertion part 41 at the lower part of the damping member 4 into the groove 31 inside the support member 3, the damping member 4 is firmly fixed to the support member 3. This design significantly improves the production and assembly efficiency of the filter element. Since the damping member 4 is made of an elastic material, which is different from the material of the support member 3, this matching insertion method facilitates the quick and accurate installation of the damping member 4 onto the support member 3 during the production process, without the need for complex fixing processes or additional adhesives. At the same time, this design also ensures the stability of the damping member 4 after assembly, preventing it from loosening or falling off in a vibration environment. Thus, while improving production efficiency, it also ensures the vibration resistance and long-term reliability of the filter element.
[0021] As a preferred embodiment, the connecting section 301 in the middle of the support member 3 is a hollow structure with an inner cavity 32. The bottom wall of the groove 31 is provided with an exhaust hole 33 communicating with the inner cavity 32, and the side wall of the inner cavity 32 is provided with a through hole 34 communicating with the outside. By adopting the above design, significant advantages are gained in the production and assembly process. When the damping member 4 is inserted into the groove 31, the exhaust hole 33 can quickly exhaust the air in the groove 31 into the inner cavity 32, and the air in the inner cavity 32 is then discharged outward through the through hole 34, thereby eliminating air resistance during assembly and allowing the damping member 4 to be assembled more smoothly. This avoids assembly difficulties or component deformation caused by air pressure accumulation, further ensuring the stability and reliability of the assembly process. The through hole 34 is located in the middle of the connecting section 301, that is, in the middle of the inner cavity 32 between the upper and lower damping members 4, which allows for rapid exhaust when both upper and lower damping members 4 are inserted. In this embodiment, the insertion part 41 is a cylindrical structure, and the shape of the groove 31 is consistent with the shape of the insertion part 41. Of course, in other embodiments, it can also be a polygonal structure.
[0022] As a preferred embodiment, the outer periphery of the insertion portion 41 is provided with an anti-detachment protrusion 42, which is interference-fitted with the groove 31. This design significantly enhances the stability of the damping element 4 on the support member 3. The interference fit between the anti-detachment protrusion 42 and the groove 31 effectively prevents the damping element 4 from loosening or falling off under long-term vibration or external force, thereby ensuring the filter element's vibration damping performance and sealing performance in a vibration environment, improving the overall reliability of the filter element, extending its service life, and reducing maintenance costs caused by the damping element 4 falling off. In other embodiments, the damping element 4 can also have its outer diameter of the insertion portion 41 interfering with the groove 31, which also ensures that the damping element does not fall off during long-term use. However, this embodiment preferably forms a tight interference fit only between the anti-detachment protrusion 42 and the groove 31. Compared to a full interference fit, this reduces assembly difficulty and improves production efficiency.
[0023] As a preferred embodiment, the filter element body 1 is provided with reinforcing ribs 5 connected to the frame 2, and a support member 3 is formed on the reinforcing ribs 5. The edge of the filter element body 1 is fixed between the frame 2, the reinforcing ribs 5, and the support member 3 by bonding or welding. The reinforcing ribs 5 can effectively disperse and bear external forces, reducing the risk of deformation of the filter element body 1 under vibration or pressure. At the same time, the combination of the support member 3 and the reinforcing ribs 5 further optimizes the stress distribution of the filter element, ensuring that the support member 3 remains stable during long-term use, thereby better performing its vibration damping function. Furthermore, the reinforcing ribs 5, the support member 3, and the frame 2 are integrally formed. Integral forming enhances the overall stability and deformation resistance of the filter element in a vibration environment. At the same time, this design reduces assembly steps, lowers production costs and assembly errors, and improves production efficiency and product quality consistency. In addition, the integrally formed structure can better ensure the synergistic effect between the support member 3 and the reinforcing ribs 5, further optimizing the vibration damping performance and sealing of the filter element, ensuring the reliability and durability of the filter element in long-term use.
[0024] Example 2 A filter element with vibration damping function, as shown in the reference. Figure 6 The only difference from Embodiment 1 is that the support member 3 is a hollow structure with an inner cavity 32. The insertion part 41 of the damping member 4 is matched and inserted into the opening of the inner cavity 32 of the support member 3. The outer diameter of the insertion part 41 is interference-fitted with the opening of the inner cavity 32. Compared with Embodiment 1, the inner wall of the support member 3 in this embodiment does not have a groove 31 and an exhaust hole 33 structure. It can still achieve the function of providing the damping member 4 for insertion and fixation. The structure is simpler, easier to produce, and lower in cost.

At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
