TECHNICAL FIELD

[0001] The application belongs to the technical field of air treatment devices, and particularly relates to a filter assembly of an air filter, the air filter and a vehicle. BACKGROUND

[0002] The air filter, referred to as an air filter for short, is a key component of the air intake system of a vehicle and plays a vital role in the operation of the vehicle. The air filter can filter out impurities such as dust and particles in the air, which prevents the impurities from entering the engine of the vehicle and thus prolongs the service life of the engine.

[0003] At present, a conventional air filter generally comprises a filter assembly, and the filter assembly comprises a filter core. In general, the filter core needs to be moved along the axial direction of the filter core to realize disassembly and assembly of the filter core. This disassembly and assembly mode requires a large operation space in the axial direction of the filter core, and the disassembly and assembly of the filter core are difficult in the case that the space in the axial direction of the filter core is limited. CONTENT OF THE UTILITY MODEL

After such arrangement, the sub-cores can be moved along a direction intersecting the axial direction of the first filter core to realize disassembly and assembly of the sub-cores, thereby realizing disassembly and assembly of the first filter core. This disassembly and assembly mode has less dependence on the space in the axial direction of the first filter core, thereby reducing the difficulty of disassembly and assembly of the first filter core.

[0007] Optionally, one of the two adjacent sub-cores is provided with a first flange, and the other is provided with a second flange, the first flange and the second flange both protrude from the sub-core in a direction intersecting the axis of the first filter core, and the first flange of one of the two adjacent sub-cores is detachably connected with the second flange of the other. After such an arrangement, the first flange and the second flange provide a connection basis between the two adjacent sub-cores, thus simplifying the connection between the two adjacent sub-cores. In addition, the first flange and the second flange have a large mating area, which helps to improve the stability and reliability of the connection between the two adjacent sub-cores.

[0008] Optionally, the filter assembly further comprises a first sealing member, at least one of the two adjacent sub-cores is provided with the first sealing member, and the two adjacent sub-cores are sealingly connected through the first sealing member. After such an arrangement, the first sealing member can seal the gap between the two adjacent sub-cores, which can reduce the leakage of gas in the inner cavity of the first filter core, and can reduce the situation that gas directly enters the inner cavity of the first filter core through the gap between the two adjacent sub-cores without being filtered by the sub-cores.

[0009] Optionally, the first sealing member comprises a first elastic sealing rib, and the first elastic sealing ribs of the two adjacent sub-cores are alternately arranged in a direction intersecting the axis of the first filter core. After such an arrangement, the first sealing members of the two adjacent sub-cores can form multiple seals in the direction intersecting the axis of the first filter core, thus improving the sealing effect of the first filter core.

[0010] Optionally, the at least two sub-cores comprise a first sub-core and a second sub-core, the two ends of the first sub-core are detachably connected with the two ends of the second sub-core in the circumferential direction of the first filter core, and the first sub-core and the second sub-core are symmetrically arranged about a first plane, and the axis of the first filter core is located in the first plane. After such an arrangement, the first sub-core and the second sub-core have the same structure, so that there is no need to distinguish between the first sub-core and the second sub-core when assembling the first filter core, thus reducing the assembly difficulty of the first filter core. Furthermore, after such an arrangement, the first filter core only comprises the first sub-core and the second sub-core in the circumferential direction, so that the number of sub-cores involved in the circumferential direction of the first filter core is small, which reduces the disassembly difficulty of the first filter core.

[0034] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art belong to the scope of protection of the present application.

[0035] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually a category and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally represents a "or" relationship between the front and rear associated objects.

[0036] The filtering assembly of the air filter, the air filter and the vehicle provided by the embodiments of the present application will be described in detail below in combination with the drawings and through specific embodiments and application scenarios.

[0037] Please refer to Figures 1 to 11As shown, the air filter assembly provided in the embodiments of the present application includes a first filter element 110, which is in a cylindrical structure, that is, the first filter element 110 has a cavity inside, and both ends of the first filter element 110 in the axial direction are provided with openings communicating with the cavity. The axial direction of the first filter element 110 is, for example, the direction indicated by the arrow A in the figure. Optionally, the first filter element 110 is made of filter paper or non-woven fabric, etc. Figure 1

[0038] The first filter element 110 includes at least two sub-core 111, each of which is arranged along the circumference of the first filter element 110 in sequence, and any two adjacent sub-cores 111 are detachably connected. The specific number of sub-cores 111 is determined according to actual needs, and the embodiments of the present application do not limit this.

[0039] In the embodiments of the present application, the first filter element 110 of the air filter assembly includes at least two sub-cores 111, each of which is arranged along the circumference of the first filter element 110 in sequence, and any two adjacent sub-cores 111 are detachably connected. After such arrangement, moving the sub-core 111 in the direction intersecting the axis of the first filter element 110 can realize the disassembly of the sub-core 111, so as to realize the disassembly of the first filter element 110. This disassembly method has less dependence on the space in the axial direction of the first filter element 110, so that the disassembly of the first filter element 110 is less difficult, which is conducive to the after-sales maintenance and repair of the first filter element 110, and can reduce the time of after-sales maintenance and repair of the first filter element 110.

[0040] As a specific implementation, the first filter element 110 is, for example, a cylindrical structure, and in actual use, the sub-core 111 is moved, for example, in the radial direction of the first filter element 110 to realize the disassembly of the sub-core 111. Of course, in other embodiments, the sub-core 111 can also be moved in other directions intersecting the axis of the first filter element 110, which is only an example in the present embodiment.

[0041] The air filter assembly provided in the embodiments of the present application will be described in detail in combination with a specific application scenario as follows:

[0042] In the case that other components are arranged in the inner cavity of the first filter element 110, for example, the second filter element 200 in the following, the existence of the other components limits the movement of the first filter element 110 as a whole in the direction intersecting the axis of the first filter element 110. In this application scenario, the first filter element 110 generally needs to be moved in the axial direction of the first filter element 110 to realize the disassembly of the first filter element 110. This disassembly method has greater dependence on the space in the axial direction of the first filter element 110, and in the case that the space in the axial direction of the first filter element 110 is limited, the disassembly of the first filter element 110 is more difficult.

[0043] ​The filter assembly provided in the embodiments of the present application can remove a part of the sub-core 111 of the first filter core 110 in a direction intersecting the axis of the first filter core 110, then remove other components in the inner cavity of the first filter core 110 in the same direction, and then remove the remaining part of the sub-core 111 in the same direction, so as to complete the disassembly of the first filter core 110. Conversely, the filter assembly provided in the embodiments of the present application can install a part of the sub-core 111 of the first filter core 110 in a direction intersecting the axis of the first filter core 110, then install other components in the inner cavity of the first filter core 110 in the same direction, and then install the remaining part of the sub-core 111 in the same direction, so as to complete the installation of the first filter core 110. The disassembly and assembly of the first filter core 110 of the filter assembly provided in the embodiments of the present application has less dependence on the space in the axial direction of the first filter core 110, so that the difficulty of the disassembly and assembly of the first filter core 110 of the filter assembly provided in the embodiments of the present application is small in the case that the space in the axial direction of the first filter core 110 is limited.

[0044] In another embodiment, referring to FIG. 1, two adjacent sub-cores 111 are provided with a first flange 1111 and a second flange 1112 respectively, the first flange 1111 and the second flange 1112 both protrude from the sub-core 111 in a direction intersecting the axis of the first filter core 110, and the first flange 1111 of one of the two adjacent sub-cores 111 is detachably connected with the second flange 1112 of the other sub-core 111. Figure 1 In the embodiment, the first flange 1111 and the second flange 1112 provide a connection basis for the connection between the two adjacent sub-cores 111, so as to simplify the connection between the two adjacent sub-cores 111. In addition, the first flange 1111 and the second flange 1112 have a large matching area, which is beneficial to improve the stability and reliability of the connection between the two adjacent sub-cores 111.

[0045] Optionally, the first flange 1111 and the second flange 1112 both protrude from the sub-core 111 in a direction perpendicular to the axis of the first filter core 110, for example, a direction indicated by an arrow B in FIG. 1.

[0046] Specifically, the first filter core 110 is, for example, a cylindrical structure, and the first flange 1111 and the second flange 1112 both protrude from the sub-core 111 in a radial direction of the first filter core 110, and the direction is, for example, perpendicular to the disassembly direction of the sub-core 111. Figure 3 In other optional embodiments, the first flange 1111 and the second flange 1112 in the foregoing embodiments can not be provided.

[0047] In another embodiment, referring to FIG. 2, two adjacent sub-cores 111 are provided with a first flange 1111 and a second flange 1112 respectively, the first flange 1111 and the second flange 1112 both protrude from the sub-core 111 in a direction intersecting the axis of the first filter core 110, and the first flange 1111 of one of the two adjacent sub-cores 111 is detachably connected with the second flange 1112 of the other sub-core 111.

[0048] Figure 3 and Figure 4 ​As shown, the filter assembly further comprises a first sealing member 120, at least one of the two adjacent sub-cores 111 is provided with the first sealing member 120, that is, the first sealing member 120 can be arranged on only one of the two adjacent sub-cores 111, or the first sealing member 120 can be arranged on both of the two adjacent sub-cores 111, and the two adjacent sub-cores 111 are sealingly matched through the first sealing member 120.

[0049] In the embodiment, the first sealing member 120 can seal the gap between the two adjacent sub-cores 111, so that the leakage of gas in the inner cavity of the first filter core 110 can be reduced, and the situation that the gas directly enters the inner cavity of the first filter core 110 through the gap between the two adjacent sub-cores 111 without being filtered by the sub-cores 111 can be reduced.

[0050] As a specific implementation, at least one of the first flange 1111 and the second flange 1112 in the foregoing is provided with the first sealing member 120. The first flange 1111 and the second flange 1112 provide a setting basis for the arrangement of the first sealing member 120, thereby reducing the difficulty of arranging the first sealing member 120.

[0051] In other optional embodiments, the filter assembly can also not comprise the first sealing member 120.

[0052] In further embodiments, the two adjacent sub-cores 111 are each provided with the first sealing member 120, and the first sealing member 120 comprises a first elastic sealing rib 121, and the first elastic sealing rib 121 corresponding to one of the two adjacent sub-cores 111 and the first elastic sealing rib 121 corresponding to the other of the two adjacent sub-cores 111 are alternately arranged in a direction intersecting the axis of the first filter core 110, and optionally, for example, are alternately arranged in the radial direction of the first filter core 110. After being arranged in this way, the first sealing members 120 corresponding to the two adjacent sub-cores 111 can form multiple seals in the direction intersecting the axis of the first filter core 110, thereby improving the sealing effect of the first filter core 110.

[0053] As a specific implementation, the first elastic sealing rib 121 is located between the corresponding first flange 1111 and the second flange 1112, and the first elastic sealing rib 121 corresponding to one of the two adjacent sub-cores 111 and the first elastic sealing rib 121 corresponding to the other of the two adjacent sub-cores 111 are alternately arranged in the protruding direction of the first flange 1111 and the second flange 1112, for example, in the direction indicated by the arrow B in FIG. 11. Figure 3

[0054] In other optional embodiments, the first elastic sealing rib 121 corresponding to one of the two adjacent sub-cores 111 and the first elastic sealing rib 121 corresponding to the other of the two adjacent sub-cores 111 can also be alternately arranged in the axial direction of the first filter core 110. ​

[0055] In a further embodiment, the first seal 120 comprises at least two first elastic sealing ribs 121, and the specific number of the first elastic sealing ribs 121 is determined according to actual needs, and each first elastic sealing rib 121 is arranged in a direction intersecting the axis of the first filter element 110, for example, the direction indicated by the arrow B. Figure 3 In this way, the at least two first elastic sealing ribs 121 of the first seal 120 can form multiple seals in the direction intersecting the axis of the first filter element 110, which also improves the sealing effect of the first filter element 110.

[0056] In other alternative embodiments, the first seal 120 can also only comprise one first elastic sealing rib 121.

[0057] In an alternative embodiment, the two adjacent sub-cores 111 are each provided with the first seal 120, the first seal 120 comprises the first elastic sealing rib 121, and the first elastic sealing rib 121 corresponding to one of the two adjacent sub-cores 111 and the first elastic sealing rib 121 corresponding to the other of the two adjacent sub-cores 111 are arranged alternately in the direction intersecting the axis of the first filter element 110, and the first seal 120 comprises at least two first elastic sealing ribs 121, and each first elastic sealing rib 121 is arranged in the same direction.

[0058] In this embodiment, the multiple first seals 120 corresponding to the two adjacent sub-cores 111 form multiple seals in the direction intersecting the axis of the first filter element 110, and the at least two first elastic sealing ribs 121 of the single first seal 120 form multiple seals in the same direction, so that the sealing effect of the first filter element 110 is better.

[0059] In actual use, the first elastic sealing rib 121 is compressed, for example, to achieve the sealing of the gap between the two adjacent sub-cores 111.

[0060] In another embodiment, referring to Figure 1As shown, the at least two sub-cores 111 include a first sub-core 111a and a second sub-core 111b, two ends of the first sub-core 111a are detachably connected with two ends of the second sub-core 111b in the circumferential direction of the first filter element 110, and the first sub-core 111a and the second sub-core 111b are symmetrically arranged about the first plane, and the axis of the first filter element 110 is located in the first plane. After being arranged in this way, the first sub-core 111a and the second sub-core 111b have the same structure, so that when the first filter element 110 is assembled, it is not necessary to distinguish the first sub-core 111a and the second sub-core 111b, thereby reducing the assembly difficulty of the first filter element 110. Furthermore, after being arranged in this way, only the first sub-core 111a and the second sub-core 111b are included in the circumferential direction of the first filter element 110, so that the number of sub-cores 111 involved in the circumferential direction of the first filter element 110 is small, which reduces the disassembly difficulty of the first filter element 110.

[0061] As a specific embodiment, reference is made to Figure 2 As shown, in the circumferential direction of the first filter element 110, for example, both ends of the first sub-core 111a are provided with first flanges 1111, and both ends of the second sub-core 111b are provided with second flanges 1112, and the corresponding first flanges 1111 and second flanges 1112 are detachably connected.

[0062] In other optional embodiments, the first sub-core 111a and the second sub-core 111b can also not be symmetric about the first plane. In addition, in the circumferential direction of the first filter element 110, other sub-cores 111 in addition to the first sub-core 111a and the second sub-core 111b can also be included, specifically, the first filter element 110 includes at least three sub-cores 111, and the at least three sub-cores 111 are arranged in sequence along the circumferential direction of the first filter element 110, for example.

[0063] As a specific embodiment, reference is made to Figures 5 to 11 As shown, the air filter provided in the embodiments of the present application also includes the filter assembly described above. The air filter provided in the embodiments of the present application has the same beneficial effects as the filter assembly described above, and will not be described here.

[0064] In another embodiment, reference is made to Figures 6 to 11 As shown, the air filter also includes a housing 300, the housing 300 includes at least two sub-housings 310, each sub-housing 310 is arranged in sequence along the circumferential direction of the housing 300, and any two adjacent sub-housings 310 are detachably connected. After being arranged in this way, the sub-housing 310 can be removed more conveniently, and after the sub-housing 310 is removed, the first filter element 110 can be disassembled more conveniently, thereby reducing the disassembly difficulty of the first filter element 110, and in the process of disassembling the first filter element 110, the housing 300 will not be easily damaged, thereby reducing waste.

[0065] Optionally, any two adjacent sub-housings 310 are connected in a detachable manner, for example, through threaded connection, snap connection or magnetic attraction.

[0066] In other optional embodiments, any two adjacent sub-housings 310 can also be connected in a non-detachable manner, for example, through welding or gluing, or the outer housing 300 can be of an integral structure.

[0067] In another embodiment, one of the two adjacent sub-cores 111 is provided with a first flange 1111, and the other is provided with a second flange 1112, and the first flange 1111 of one of the two adjacent sub-cores 111 and the second flange 1112 of the other are clamped between the two adjacent sub-housings 310 to indirectly detachably connect the two adjacent sub-cores 111.

[0068] In the present embodiment, the detachable connection of the two adjacent sub-housings 310 indirectly realizes the detachable connection of the two adjacent sub-cores 111, so that no additional components are needed to connect the two adjacent sub-cores 111, thereby reducing the number of components involved in the air filter and thus reducing the difficulty of disassembling the air filter.

[0069] It should be noted that in the present embodiment, there is no direct connection relationship between the two adjacent sub-cores 111, and the two adjacent sub-cores 111 are indirectly detachably connected by the pressure applied by the sub-housing 310. In actual use, when the corresponding sub-housing 310 is removed, the connection relationship between the two adjacent sub-cores 111 is also removed.

[0070] In other optional embodiments, the first flange 1111 of one of the two adjacent sub-cores 111 and the second flange 1112 of the other can also be located in the inner cavity of the outer housing 300.

[0071] In another embodiment, the first flange 1111 is in sealing cooperation with the corresponding sub-housing 310, and the second flange 1112 is in sealing cooperation with the corresponding sub-housing 310.

[0072] In a further embodiment, the filter assembly includes the first sealing element 120 mentioned above. The first sealing element 120 has a cavity, and the first flange 1111 and the second flange 1112 are respectively inserted into different cavities. That is, the first flange 1111 and the second flange 1112 correspond to different first sealing elements 120. More specifically, different first sealing elements 120 are respectively fitted on the first flange 1111 and the second flange 1112. The first flange 1111 is sealed with the corresponding sub-housing 310 through its corresponding first sealing element 120, and the first flange 1111 is sealed with the second flange 1112 through its corresponding first sealing element 120. The second flange 1112 is sealed with the corresponding sub-housing 310 through its corresponding first sealing element 120, and the second flange 1112 is sealed with the corresponding first flange 1111 through its corresponding first sealing element 120.

[0073] In this embodiment, the first sealing member 120 corresponding to the first flange 1111 can simultaneously seal the gap between the first flange 1111 and the second flange 1112, as well as the gap between the first flange 1111 and the corresponding sub-housing 310. Similarly, the first sealing member 120 corresponding to the second flange 1112 can simultaneously seal the gap between the first flange 1111 and the second flange 1112, as well as the gap between the second flange 1112 and the corresponding sub-housing 310. This results in a smaller number of components involved in the air filter, thereby reducing the assembly difficulty of the air filter.

[0074] As one specific implementation method, refer to Figure 4 and Figure 7 As shown, the first sealing element 120 includes, for example, a main body 123, a first elastic sealing rib 121 (mentioned above), and a second elastic sealing rib 122. The main body 123 has a cavity. Both the first elastic sealing rib 121 and the second elastic sealing rib 122 are located in the main body 123. The first elastic sealing rib 121 is located between the first flange 1111 and the second flange 1112 and is used to seal the gap between the first flange 1111 and the second flange 1112. The second elastic sealing rib 122 is located on the side of the first flange 1111 opposite to the second flange 1112 and is used to seal the gap between the first flange 1111 and the corresponding sub-housing 310. Alternatively, the second elastic sealing rib 122 is located on the side of the second flange 1112 opposite to the first flange 1111 and is used to seal the gap between the second flange 1112 and the corresponding sub-housing 310. More specifically, the first sealing element 120 is, for example, an elastic sealing strip.

[0075] In a further embodiment, reference is made to... Figure 6As shown, one side of the first flange 1111 away from the second flange 1112 and one side of the second flange 1112 away from the first flange 1111 are both provided with the second sealing member 130, the first flange 1111 is in sealing cooperation with the corresponding sub-housing 310 through the second sealing member 130, and the second flange 1112 is in sealing cooperation with the corresponding sub-housing 310 through the second sealing member 130. After being arranged in this way, the gap between the first flange 1111 and the sub-housing 310 is sealed by the separate second sealing member 130, the gap between the second flange 1112 and the sub-housing 310 is sealed by the separate second sealing member 130, and the second sealing member 130 does not participate in the sealing of the gap between the first flange 1111 and the second flange 1112, so that when the second sealing member 130 is replaced, the sealing between the first flange 1111 and the second flange 1112 is basically not affected.

[0076] As a specific embodiment, the second sealing member 130, for example, includes a third elastic sealing rib, and the third elastic sealing rib is, for example, bonded to one side of the first flange 1111 away from the second flange 1112 or one side of the second flange 1112 away from the first flange 1111, and the first sealing member 120, for example, only includes the first elastic sealing rib 121, and the first elastic sealing rib 121 is, for example, bonded to one side of the first flange 1111 toward the second flange 1112 or one side of the second flange 1112 toward the first flange 1111. More specifically, the first sealing member 120 and the second sealing member 130, for example, are both cured by polyurethane (PU) glue. In addition, in other embodiments, the first sealing member 120 and the second sealing member 130 can also be partially embedded in the first flange 1111 or the second flange 1112 to arrange the first sealing member 120 on the first flange 1111 or the second flange 1112 and arrange the second sealing member 130 on the first flange 1111 or the second flange 1112. In the embodiments of the present application, the connection mode between the first sealing member 120 and the first flange 1111 and the second flange 1112 and the connection mode between the second sealing member 130 and the first flange 1111 and the second flange 1112 are not limited. In addition, in the embodiments of the present application, the shapes and sizes of the first elastic sealing rib 121, the third elastic sealing rib, and the second elastic sealing rib 122 in the foregoing are also not limited, and can be set according to actual needs.

[0077] In another embodiment, referring to Figure 8 As shown, one of the two adjacent sub-housings 310 is provided with a positioning column 320, and the other is provided with a positioning hole, and the positioning column 320 is inserted into the positioning hole. In the actual assembly process, the relative positions of the two adjacent sub-housings 310 can be positioned more conveniently and quickly through the cooperation of the positioning column 320 and the positioning hole, thereby reducing the assembly difficulty of the shell 300.

[0078] Further, one end of the positioning column 320 is inserted through the positioning hole and fastened by a nut, for example, to achieve detachable connection of the two adjacent sub-housings 310. After being arranged in this way, the positioning column 320 has the functions of positioning the positions of the two adjacent sub-housings 310 and connecting the two adjacent sub-housings 310, which makes the number of components involved in the air filter smaller, thereby further reducing the assembly difficulty of the housing 300.

[0079] Further, referring to Figure 8 the first flange 1111 of one of the two adjacent sub-cores 111 and the second flange 1112 of the other are clamped between the two adjacent sub-housings 310, and the positioning column 320 and the first flange 1111 and the positioning column 320 and the second flange 1112 are arranged, for example, in a direction intersecting the axis of the first filter core 110, to prevent the positioning column 320 from interfering with the first flange 1111 and the second flange 1112.

[0080] In other optional embodiments, the positioning column 320 and the positioning hole can also not be provided.

[0081] In another embodiment, one of the two adjacent sub-housings 310 is provided with a first protruding portion 311, and the other is provided with a second protruding portion 312. The first protruding portion 311 and the second protruding portion 312 both protrude from the sub-housing 310 in a direction intersecting the axis of the first filter core 110. Optionally, the first protruding portion 311 and the second protruding portion 312 both protrude from the sub-housing 310, for example, in the radial direction of the first filter core 110. The first protruding portion 311 of one of the two adjacent sub-housings 310 is detachably connected to the second protruding portion 312 of the other. Optionally, the protruding directions of the first protruding portion 311, the second protruding portion 312, the first flange 1111, and the second flange 1112 are the same, for example.

[0082] In this embodiment, the provision of the first protruding portion 311 and the second protruding portion 312 provides a connection basis for the connection between the two adjacent sub-housings 310, thereby reducing the connection difficulty between the two adjacent sub-housings 310 and helping to improve the reliability of the connection between the two adjacent sub-housings 310.

[0083] Further, the positioning column 320 in the foregoing is provided on the first protruding portion 311 or the second protruding portion 312, and the positioning hole in the foregoing is provided on the first protruding portion 311 or the second protruding portion 312. In this way, the first protruding portion 311 and the second protruding portion 312 provide a setting basis for the positioning column 320 and the positioning hole, thereby reducing the setting difficulty of the positioning column 320.

[0084] In other optional embodiments, the first protruding portion 311 and the second protruding portion 312 can also not be provided.

[0085] In another embodiment, at least two sub-shells 310 include a first sub-shell 310a and a second sub-shell 310b. In the circumferential direction of the outer shell 300, the two ends of the first sub-shell 310a are detachably connected to the two ends of the second sub-shell 310b, respectively.

[0086] In this embodiment, the outer shell 300 includes only the first sub-shell 310a and the second sub-shell 310b in the circumferential direction. As a result, the number of sub-shells 310 involved in the circumferential direction of the outer shell 300 is small, which also reduces the assembly difficulty of the outer shell 300.

[0087] As one specific implementation method, refer to Figure 9 As shown, in the circumferential direction of the outer casing 300, the first sub-casing 310a has a first protrusion 311 at both ends, and the second sub-casing 310b has a second protrusion 312 at both ends, and the corresponding first protrusion 311 and second protrusion 312 are detachably connected.

[0088] Optionally, refer to Figure 8 As shown, the outer casing 300 may also include a first end cap 331 and a second end cap 332. The first end cap 331 and the second end cap 332 are located at opposite ends in the axial direction of the outer casing 300. The axial direction of the outer casing 300 is, for example, the same as the axial direction of the first filter element 110. The first end cap 331 is connected to the first sub-casing 310a or the second sub-casing 310b, and the second end cap 332 is connected to the first sub-casing 310a or the second sub-casing 310b. The first end cap 331 and the second end cap 332, for example, cooperate with opposite ends in the axial direction of the first filter element 110 to restrict the movement of the first filter element 110 along its own axial direction.

[0089] This application also provides a vehicle that includes the air filter described above. Optionally, the vehicle is, for example, an off-road vehicle, and more specifically, an off-road passenger vehicle. The vehicle provided in this application has the same beneficial effects as the air filter described above, and will not be repeated here.

[0090] Furthermore, the air filter is located, for example, in the front engine compartment of the vehicle, and the axis of the first filter element 110 is, for example, in the same direction as the horizontal direction, and there are, for example, no obstructions above the air filter. With this configuration, in actual use, with the front engine compartment hood open, there is a large operating space in the vertical direction, and the first filter element 110 can be easily installed and removed in the vertical direction.

[0091] Furthermore, refer to Figure 6As shown, the first filter element 110 includes, for example, the first sub-core 111a and the second sub-core 111b mentioned above. The outer casing 300 includes, for example, the first sub-shell 310a and the second sub-shell 310b mentioned above, with the second sub-shell 310b fixedly disposed. The first sub-shell 310a is located above the second sub-shell, and the first sub-core 111a is located above the second sub-core 111b. In this layout, for example, first along the vertical direction, for example... Figure 6 In the direction indicated by the middle arrow C, remove the first sub-shell 310a, then remove the first sub-core 111a vertically, and then remove the second sub-core 111b to complete the disassembly of the first filter element 110. Conversely, install the second sub-core 111b, the first sub-core 111a, and the first sub-shell 310a in the opposite order and in the opposite direction to complete the installation of the first filter element 110.

The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
