[0002] Air filter is mainly applied in pneumatic machinery, internal combustion machinery and other fields, and its role is to provide clean air for these mechanical equipment to prevent these mechanical equipment from inhaling air with impurity particles in the work and increasing the probability of abrasion and damage. The main components of air filter are filter element and shell, wherein the filter element is the main filtering part and bears the filtering work of gas, and the shell is the external structure for providing necessary protection for the filter element. Among them, the honeycomb type filter element is widely used in air filter due to its high space utilization, compact structure and high filtering efficiency.

[0003] The honeycomb type air filter element has an air inlet face and an air outlet face on the same axis, and such structural feature can make the honeycomb type air filter element have very low air resistance value, so that the system air intake of the engine is more smooth, thereby improving the service life of the air filter. At the same time, such structure leads to the sealing structure between the honeycomb type filter element and the shell which must adopt the matching mode of radially outward. At present, the sealing structure of the honeycomb type air filter element on the market usually coats glue on the inner wall of the sealing support ring first, then puts the sealing support ring on the honeycomb type air filter element and aligns the end face, and finally presses the periphery to make the sealing support ring adhere to the radial face of the honeycomb type air filter element. The connection between the filter element and the sealing support ring by adhesion is prone to poor adhesion of the sealing support face, which leads to poor sealing and even the problem of falling off of the sealing support ring to make the air filter invalid. Therefore, it is necessary to provide a honeycomb type filter element and air filter which can effectively improve the connection strength. SUMMARY

DETAILED DESCRIPTION

[0022] The utility model will be further explained in detail in connection with the attached drawing and specific embodiment.

[0023] As Figure 1 shown, the honeycomb filter core provided by the utility model includes a core body 1 and a sealing support ring 2 arranged on the radial outer side surface of the core body 1, wherein the core body 1 serves as the filtering main body of the filter core, and the sealing support ring 2 serves as the supporting component of the filter core installed in the air filter and plays a sealing role. The sealing support ring 2 is integrally formed on the radial outer side surface of the core body 1 in a mold forming mode, the utility model integrally forms the sealing support ring 2 on the core body 1 in a mold forming mode, so that the sealing support ring 2 is integrally connected with the core body 1 at the same time of forming. Compared with the connecting mode of adhesion in the traditional structure, the utility model can effectively improve the connection strength between the honeycomb air filter core and the sealing support ring 2, improve the sealing performance, prolong the service life of the honeycomb filter core to a certain extent, and effectively ensure the product quality of the honeycomb filter core. In actual production, glue can be injected into the mold with a cavity matched with the sealing support ring 2, and the sealing support ring 2 is integrally formed on the core body 1 at the same time of forming by using the adhesion of the glue foaming process.

[0024] In some embodiments, the sealing support ring 2 comprises a connecting part 21 and a hanging support part 22 integrally formed with the connecting part 21. The connecting part 21 is integrally connected with the radially outer side of the core 1. Specifically, the inner side of the connecting part 21 is an adhesive surface connected with the core 1, and the outer side is a pressing surface abutting against the shell 4. Preferably, the outer diameter of the outer side of the connecting part 21 gradually decreases from top to bottom, so that when the filter core is installed in the shell 4 from bottom to top, the connecting part 21 can generate a certain extrusion on the inner wall of the shell 4 by deformation, thereby improving the sealing between the filter core and the shell 4. Further preferably, the outer side of the connecting part 21 is an arc surface or a broken line surface, which facilitates the installation of the filter core in the shell 4 and enables the filter core to be clamped in the inner wall of the shell 4. The hanging support part 22 is located above the connecting part 21 and is arranged to extend outwardly along the radial direction of the core 1, so that the outer diameter of the hanging support part 22 is greater than the maximum outer diameter of the connecting part 21, which enables the hanging support part 22 to form an outwardly protruding hanging ear, thereby enabling the filter core to be easily hung in the shell 4. Preferably, a V-shaped groove 3 is provided between the hanging support part 22 and the core 1, which provides a deformation avoidance space for the hanging support part 22 and is beneficial to further providing sealing. Further preferably, the upper end surface of the hanging support part 22 is lower than the upper end surface of the core 1, which enables the air inlet end surface of the core 1 to be higher than the connection between the sealing support ring 2 and the shell 4, thereby effectively avoiding air leakage from the connection to reduce the air tightness of the air cleaner.

[0025] As shown in Figure 2 The air cleaner of the present application has simple structure, low production cost, and high connection strength and sealing performance, which effectively ensures the product quality and prolongs the service life of the air cleaner to a certain extent.

[0026] In some embodiments, specifically, the shell 4 comprises a shell body 5 and a cover 6 having an air inlet, and the shell body 5 and the cover 6 are detachably fixedly connected through a spring buckle 7 or the like connecting member. The core 1 is installed in the cavity formed between the shell body 5 and the cover 6, and the sealing support ring 2 is fixedly arranged between the shell body 5 and the cover 6. More specifically, as shown in Figure 3As shown, the upper end of the shell 5 is provided with a mounting flange 51 matched with the hanging support part 22 of the sealing support ring 2, the mounting flange 51 provides a hanging space for the hanging support ring of the sealing support ring 2. The lower end of the cover 6 is provided with a pressing flange 61 matched with the hanging support part 22 of the sealing support ring 2, the sealing support ring 2 is clamped between the mounting flange 51 and the pressing flange 61, and the gap height between the mounting flange 51 and the pressing flange 61 is slightly smaller than the thickness of the hanging support part 22, so that the mounting flange 51 and the pressing flange 61 can extrude the hanging support part 22 to deform when the cover 6 is fixedly connected to the shell 5. In order to further improve the sealing performance of the air filter, a sealing ring 52 is vertically arranged on the mounting flange 51, the sealing ring 52 is arranged between the pressing flange 61 and the sealing support ring 2, and the height of the sealing ring 52 is smaller than the thickness of the hanging support part 22, the sealing support ring 2 and the sealing ring 52 are in radial clearance fit, and the hanging support part 22 is also provided with a deformation space, so that the sealing performance of the filter is better improved.

[0027] In summary, the honeycomb filter element of the utility model is integrally formed with the sealing support ring 2 on the outside of the core body 1, which can effectively improve the connection strength between the honeycomb air filter element and the sealing support ring 2, and well ensure the sealing performance, and the structure is simple and reasonable in design, and the service life of the honeycomb filter element is prolonged to a certain extent. The air filter of the utility model is provided with the above-mentioned honeycomb filter element in the casing 4, and has the advantages of simple structure, low production cost, convenient installation, high connection strength, good sealing performance, effective guarantee of product quality, and prolonged service life of the filter to a certain extent.

[0028] The above-mentioned embodiments are only preferred embodiments of the utility model, and cannot be used to limit the range of protection of the utility model, and any non-essential changes and replacements made by those skilled in the art on the basis of the utility model all belong to the range of protection required by the utility model.
