Description

Technical Field

[0001] The utility model belongs to the technical field of automobile air filter cores, and in particular relates to an automobile air filter core. Background Art

[0002] A car air filter is a device used to filter impurities from the air entering the car engine. It is mainly used to maintain the cleanliness of the air entering the car engine, thereby ensuring the stable operation of the car engine. A car air filter is generally composed of two parts: a filter element and a housing. The housing is used to limit the assembly of the filter element and provide filtering space for the air to be filtered, while the filter element is the core component for filtering dust from the air.

[0003] The common automobile air filter core is mainly composed of filter material, mesh, outer frame and sealing strip. Among them, the filter material is mainly used to filter and separate pollutants in the air, the mesh is used to support and fix the filter material, the outer frame plays a role in protecting the filter material and filter mesh, and the sealing strip is usually set on the periphery of the filter element to ensure the assembly sealing of the filter element.

[0004] In the prior art, most automobile air filter cores are arranged as an integral whole, and the entire automobile air filter core needs to be disassembled and replaced when it is replaced. However, it is well known that the dust content of dust-laden air at the air inlet position is relatively large, and with the filtration and diffusion of the dust-laden air, the dust content of the dust-laden air far away from the air inlet position is relatively low. As a result, in actual application, the automobile air filter core is prone to dust adhesion and blockage of the filter material near the air inlet position, while the filtering effect of the filter material on the other side is still good. When the automobile air filter core is replaced in this case, the utilization rate of the automobile air filter core is low, resulting in a certain degree of waste of resources and an increase in the subsequent maintenance and use costs of the automobile air filter core.

[0005] Therefore, in response to the above-mentioned technical problems, it is necessary to provide a kind of automobile air filter core.

[0006] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

The module sealing ring can fully seal the core frame by mutual extrusion between the extrusion protrusion and the module sealing ring.

[0014] In one or more embodiments of the utility model, the outer side of the core frame is threadedly connected with a plurality of evenly distributed locking bolts, which are used to assemble and fix the core frame.

[0016] In one or more embodiments of the utility model, the gap between the pair of first positioning pins is larger than the gap between the pair of second positioning pins. By setting the gap between the pair of first positioning pins larger than the gap between the pair of second positioning pins, the core frame can be foolproofed by the mutual cooperation between the pair of first positioning pins and the second positioning pins, thereby improving the convenience of assembling the core frame.

[0017] In one or more embodiments of the utility model, the first and second positioning pins are both tapered, and the top diameters of the first and second positioning pins are smaller than the bottom diameters.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0030] like Figures 1 to 6 As shown, an automobile air filter element in one embodiment of the utility model comprises: an assembly fixing frame 1 and a plurality of groups of modular filter element components 2.

[0031] like Figure 1 As shown, the assembly fixing frame 1 is integrally formed with a limiting horizontal plate 101 and a limiting vertical plate 102, which are staggered. The limiting horizontal plate 101, the limiting vertical plate 102 and the assembly fixing frame 1 cooperate with each other to facilitate assembly and limiting of multiple groups of modular filter element components 2.

[0032] Specifically, the assembly fixing frame 1, the limiting horizontal plate 101 and the limiting vertical plate 102 cooperate to form a plurality of assembly limiting holes, through which the modular filter element assembly 2 is assembled and limited.

[0033] It is worth noting that the inner walls of the plurality of assembly limiting holes are all provided with supporting limiting grooves, which are arranged in cooperation with the core frame 201. The core frame 201 is assembled and limited by the supporting limiting grooves.

[0034] like Figure 1 to Figure 2As shown, a sealing ring 3 is sleeved on the outer side of the assembly fixing frame 1, and the sealing ring 3 protrudes from the upper surface of the assembly fixing frame 1. The sealing ring 3 is convenient for sealing and protecting the assembly state of the assembly fixing frame 1 through the contraction of the sealing ring 3, thereby ensuring the effect of filtering the air.

[0035] like Figures 1 to 3 As shown, multiple groups of modular filter element assemblies 2 are fixedly assembled in the assembly limit hole, and the modular filter element assembly 2 includes a core frame 201, and the core frame 201 is snap-fitted and assembled in the assembly limit hole. The core frame 201 is used to assemble, fix and integrally disassemble multiple groups of filter screens 202.

[0036] like Figures 4 to 5 As shown, a module sealing ring 204 is sleeved on the outer side of the core frame 201. The module sealing ring 204 plays a role of sealing and limiting the core frame 201 and the assembly limiting hole.

[0037] like Figures 4 to 5 As shown, the outer side of the core frame 201 is integrally formed with an extrusion protrusion 205. The extrusion protrusion 205 and the module sealing ring 204 are mutually extruded so that the module sealing ring 204 can fully seal the core frame 201.

[0038] like Figures 1 to 5 As shown, the outer side of the core frame 201 is threadedly connected with a plurality of evenly distributed locking bolts 206. The core frame 201 is assembled and fixed by the plurality of locking bolts 206.

[0039] like Figures 1 to 3 As shown, a pair of first positioning pins 207 are inserted into one side of the core frame 201, and a pair of second positioning pins 208 are inserted into the side of the core frame 201 away from the first positioning pins 207. The pair of first positioning pins 207 and the second positioning pins 208 are both fixedly assembled in the supporting limit groove. The pair of first positioning pins 207 and the second positioning pins 208 play the role of assembly limit for the core frame 201, thereby ensuring the assembly stability of the core frame 201.

[0040] Specifically, the gap between the pair of first positioning pins 207 is larger than the gap between the pair of second positioning pins 208. By setting the gap between the pair of first positioning pins 207 to be larger than the gap between the pair of second positioning pins 208, the core frame 201 can be foolproofed by the mutual cooperation between the pair of first positioning pins 207 and the second positioning pins 208, thereby improving the convenience of assembling the core frame 201.

[0041] The first and second positioning pins 207 and 208 are both tapered, and the top diameters of the first and second positioning pins 207 and 208 are smaller than the bottom diameters. By setting the first and second positioning pins 207 and 208 in tapered shapes, the first and second positioning pins 207 and 208 can be used to assist in fixing and limiting the core frame 201.

[0042] like Figures 4 to 5 As shown, multiple groups of evenly distributed filter screens 202 are fixedly connected in the core frame 201. The multiple groups of filter screens 202 play the role of supporting and limiting the filter cloth 203 and blocking adhesion, thereby improving the use stability of the filter cloth 203.

[0043] like Figures 4 to 5 As shown, filter cloth 203 is mounted on the top of the plurality of filter screens 202, and both ends of the filter cloth 203 are fixedly connected to the core frame 201, and the filter cloth 203 cooperates with the core frame 201 to form a filter chamber. The filter cloth 203 filters the air entering the air inlet.

[0044] like Figure 6 As shown, the outer side of the assembly fixing frame 1 is fixedly mounted with a filter lower housing 4, and the upper part of the filter lower housing 4 is fixedly mounted with a filter upper housing 5. The assembly fixing frame 1 is assembled by the cooperation of the filter lower housing 4 and the filter upper housing 5, which provides a basis for the air filtering process.

[0045] During specific use, multiple groups of modular filter element assemblies 2 are assembled in the assembly limit holes through a pair of first positioning pins 207 and a second positioning pin 208, and the core frame 201 is locked and fixed by multiple groups of locking bolts 206. In the process of locking and fixing the core frame 201 by the locking bolts 206, the module sealing ring 204 seals the edge of the core frame 201 through the interaction between the extrusion protrusion 205 and the module sealing ring 204.

[0046] After the assembly is completed, the assembly fixing frame 1 is assembled as a whole in the lower filter shell 4, and the automobile air filter is formed by the cooperation between the lower filter shell 4 and the upper filter shell 5. When the outside air enters the automobile air filter along the air inlet of the lower filter shell 4, the air is filtered by the cooperation of the filter cloth 203 and the multiple groups of filter screens 202, and the filtered air can be discharged from the exhaust port on the upper filter shell 5.

[0047] During use, different modular filter element assemblies 2 can be disassembled, assembled and replaced according to the degree of dirtiness of the multiple groups of modular filter element assemblies 2. There is no need to replace the entire vehicle air filter element, which improves the utilization rate of the vehicle air filter element and reduces the use and maintenance cost of the vehicle air filter element.
