[0027] Combine Figure 3 and Figure 4 As shown, in one embodiment, a sealing assembly 100 is used to seal the housing 20 of the air filter 10, and the sealing assembly 100 includes a first sealing structure 110 and a second sealing structure 120 located in the housing 20, the first sealing structure 110 includes a first mounting portion 112 and a first sealing member 111, the filter element holder 40 of the air filter 10 is installed on the first mounting portion 112, and a first sealing groove 1124 is formed between the first mounting portion 112 and the filter element holder 40, the first sealing member 111 is arranged in the first sealing groove 1124 to seal the second gap 50 between the first mounting portion 112 and the filter element holder 40, the second sealing structure 120 is arranged around the outer periphery of the first mounting portion 112, and the second sealing structure 120 includes a second sealing member 123 for sealing the second gap 50 between the outer peripheral wall 80 of the filter element holder 40 and the housing 20.

[0028] Specifically, the outer peripheral wall 80 of the filter cartridge holder 40 refers to the wall surface of the filter cartridge holder 40 that contacts the second protrusion 1122. A second gap 50 is formed at a predetermined distance between this wall surface and the second protrusion 1122. Dust is easily drawn in through the second gap 50 and accumulates in the first sealing groove 1124, which poses a risk of dust being difficult to clean and easily drawn into the clean cavity 30 from the first sealing groove 1124. The first gap 70 refers to the gap between the rib 41 and the first protrusion 1121, away from the second gap 50. The first sealing member 111 helps prevent dust from entering the first gap 70 and contaminating the clean cavity 30.

[0029] On the one hand, the above-mentioned sealing assembly 100 is conducive to the installation of the filter element bracket 40 by setting the first mounting portion 112. On the other hand, the first mounting portion 112 and the filter element bracket 40 form a first sealing groove 1124. The first sealing member 111 is installed in the first sealing groove 1124, which is conducive to preventing dust from entering the clean cavity 30 of the air filter 10. Furthermore, by setting the second sealing structure 120, a secondary sealing effect can be formed on the clean cavity 30 of the air filter 10 at the periphery of the first mounting portion 112, which is conducive to preventing dust from entering the first sealing groove 1124 through the second gap 50 between the outer peripheral wall 80 of the filter element bracket 40 and the shell 20, thereby preventing dust from entering the clean cavity 30 of the air filter 10 and ensuring the life of the engine.

[0030] It should be noted that the filter element bracket 40 can be detachably installed on the housing 20, and the filter element 60 is installed on the filter element bracket 40. However, when maintaining and replacing the filter element 60 of the air filter 10, it is generally not necessary to disassemble the filter element bracket 40. It is only necessary to directly replace the filter element 60 when the filter element bracket 40 is installed in the housing 20.

[0031] Combine Figure 4As shown, in some embodiments, the second sealing structure 120 includes a mounting edge 121 provided on the housing 20, and a second sealing groove 124 is formed between the mounting edge 121 and the outer peripheral wall 80 of the filter element holder 40. The second sealing member 123 is provided in the second sealing groove 124, and the second sealing member 123 abuts against the outer peripheral wall 80 of the filter element holder 40 under the support of the mounting edge 121. Specifically, the mounting edge 121 is provided on one surface of the housing 20, and the mounting edge 121 is a protruding member or bump raised on the surface of the housing 20. By providing the mounting edge 121 on the surface of the housing 20, on the one hand, the mounting edge 121 can be used to snap into the third mounting portion 220 of the shell cover 200, thereby achieving the installation and matching of the housing 20 and the shell cover 200. The above-mentioned third mounting portion includes protruding portions located on both sides of the mounting edge 121 and a connecting portion connecting the protrusions on both sides. On the other hand, the third mounting portion 220 can be pressed and supported by the mounting edge 121, so that the third mounting portion 220 is raised a short distance by the above-mentioned supporting effect, thereby forming a gap between the pressing portion 221 and the flange 122 on the shell 20, and the gap is the second sealing groove 124, and the second sealing groove 124 is connected to the second gap 50. Furthermore, it is conducive to installing the second sealing member 123 in the second sealing groove 124, thereby ensuring the sealing effect of the second gap 50. The above-mentioned structure is reasonable, which prevents dust from entering the first sealing groove 1124 from the second gap 50, and solves the problem that dust in the traditional sealing structure will accumulate in the first sealing groove 1124 and enter the clean cavity 30, thereby improving the life of the engine.

[0032] Combine Figure 4 As shown, in one embodiment, a fourth seal 222 is installed between the mounting edge 121 and the third mounting portion 220. The fourth seal 222 can, on the one hand, buffer the installation cooperation between the shell 20 and the shell cover 200, and on the other hand, further enhance the sealing effect of the sealing assembly 100 on the clean cavity 30.

[0033] Combine Figure 4As shown, in some embodiments, the second seal 123 forms an interference fit with the mounting flange 121 and the filter cartridge holder 40. Specifically, the second seal 123 is sandwiched between the mounting flange 121 and the filter cartridge holder 40, and the outer peripheral wall 80 of the filter cartridge holder 40 and a wall surface of the second protrusion 1122 abut against each other, forming a second gap 50. The mounting flange 121 is positioned on the surface of the housing 20 with a small gap therebetween. It should be noted that this small gap refers to the width of the flange 122, which is the small section of the housing 20 surface located between the rib 41 and the mounting flange 121. The arrangement of the flange 122 allows the second seal 123 to press against the flange 122 and be sandwiched between the mounting flange 121 and the filter element holder 40. The second seal 123 is always in a squeezed state, i.e., it forms an interference fit with the mounting flange 121 and the filter element holder 40. The second seal 123 is a sealing ring made of an elastic material (such as rubber). Therefore, the elasticity of the sealing ring ensures that even when the rib 41 shakes within the mounting groove formed by the first mounting portion 112 and the second mounting portion 210, the second seal 123 can maintain its sealing performance, thereby preventing dust from entering the second gap 50. The above arrangement helps to cut off the connection between the second gap 50 and the outside world, ensuring that external dust cannot enter the first sealing groove 1124 through the second gap 50, thereby ensuring that dust does not accumulate in the first sealing groove 1124 and risk entering the clean cavity 30, thereby improving the life of the engine.

[0034] Combine Figure 4As shown, in some embodiments, the shell 20 has a first protrusion 1121, a second protrusion 1122, and a first connecting portion 1123. The first protrusion 1121 and the second protrusion 1122 are connected through the first connecting portion 1123 to form a first mounting portion 112. The first sealing groove 1124 is provided in the first mounting portion 112, and the first sealing member 111 is installed in the first sealing groove 1124. Specifically, the rib 41 is snapped into the first mounting portion 112, and through the arrangement of the first protrusion 1121 and the second protrusion 1122, the filter element bracket 40 is in a "T" shape, wherein one end of the rib 41 is snapped into the first mounting portion 112, and in the horizontal direction, the two opposite wall surfaces of the rib 41 are respectively fitted and abutted against the first protrusion 1121 and the second protrusion 1122. It should be noted that the rib 41 has two ends, and the above-mentioned two ends refer to the two protruding ends in the T-shaped structure. The one end of the rib 41 snapped into the first mounting portion 112 refers to the end of the above-mentioned two ends close to the first mounting portion 112 snapped into the first mounting portion 112. In addition, the opposite wall surfaces of the rib 41 refer to the two opposite wall surfaces corresponding to the end snapped into the first mounting portion 112. Since the first protrusion 1121 and the second protrusion 1122 are connected by the first connecting portion 1123 and are formed as one piece, the distance between the first protrusion 1121 and the second protrusion 1122 is constant. Therefore, the rib 41 will not shake too much in the horizontal direction under the restriction of the first protrusion 1121 and the second protrusion 1122, thereby ensuring the size of the second gap 50 formed between the wall surface of the side of the rib 41 away from the static cavity in the horizontal direction and the wall surface of the second protrusion 1122, and the distance between the rib 41 and the mounting edge 121 will not change too much due to the vibration of the rib 41, thereby achieving the stability of the structure after installation. The first sealing groove 1124 is a groove structure of the first mounting portion 112. The first sealing member 111 is a sealing ring, which is installed in the first sealing groove 1124 through the first sealing member 111. The first sealing member 111 is in an extruded state, that is, it is an interference fit with the first protrusion 1121 and the second protrusion 1122, thereby preventing dust from being introduced into the clean cavity 30 through the first sealing groove 1124, thereby improving the life of the engine.

[0035] Combine Figure 4As shown, in some embodiments, the filter element holder 40 has a rib 41, which is installed in the first installation portion 112 and presses the first sealing member 111 against the surface of the first connecting portion 1123. Specifically, the first sealing member 111 is installed between the first protrusion 1121 and the second protrusion 1122, and is subjected to the squeezing force of the first protrusion 1121 and the second protrusion 1122 in the horizontal direction. At the same time, the rib 41 is squeezed in the vertical direction by the first connecting portion 1123 and the second connecting portion 211. Therefore, the first sealing member 111 is squeezed in multiple directions at the same time, which is conducive to the first sealing member 111 being firmly fixed in the first sealing groove 1124. In addition, due to its own elastic properties, the first sealing member 111 is ensured to be well adhered to each contacting surface, thereby ensuring the sealing effect of the first sealing structure on the clean cavity 30.

[0036] Combine Figures 1-4As shown, in some embodiments, the air filter 10 includes a housing cover 200 having a second mounting portion 210 and a third mounting portion 220. The rib 41 is mounted in a mounting groove formed by the first mounting portion 112 and the second mounting portion 210. The second sealing structure 120 includes a mounting edge 121 provided on the housing 20, and the third mounting portion 220 is configured to be mounted and engaged with the mounting edge 121. Specifically, the housing cover 200 is connected to the housing 20 via bolts. The second mounting portion 210 includes a clamping portion 213, a pressing portion 221, and a second connecting portion 211. The clamping portion 213 and the pressing portion 221 are connected via the second connecting portion 211. The clamping portion 213, the pressing portion 221, and the second connecting portion 211 are integrally formed on the housing cover 200, and the inner surfaces of the clamping portion 213, the pressing portion 221, and the second connecting portion 211 form a groove. Similarly, the inner surfaces of the first protrusion 1121, the second protrusion 1122, and the first connecting portion 1123 also form a groove, and the upper and lower grooves are connected to form a mounting groove for mounting the filter element bracket 40. The rib 41 is installed in the mounting groove formed by the first mounting portion 112 and the second mounting portion 210, wherein the end of the rib 41 away from the first mounting portion 112 is snapped into the groove surrounded by the second mounting portion 210, and the two opposite wall surfaces of the rib 41 respectively abut against the clamping portion 213 and the pressing portion 221. Since the spacing between the clamping portion 213 and the pressing portion 221 is constant, the rib 41 will not shake too much in the left and right directions under the restriction of the clamping portion 213 and the pressing portion 221, so that This ensures that the size of the gap formed between the rib 41 and the second protrusion 1122 and the distance between the rib 41 and the mounting edge 121 will not change significantly due to the vibration of the rib 41. When the distance between the rib 41 and the mounting edge 121 remains constant, the second sealing member 123 can be kept in an extruded state, that is, the second sealing member 123 can be tightly fitted to the mounting edge 121 and the rib 41, which is beneficial to avoid the sealing failure of the second sealing member 123 due to loosening.

[0037] Combine Figure 4 As shown, in some embodiments, the housing cover 200 is provided with a pressing portion 221, and the pressing portion 221 is used to press the second sealing member 123 against the housing 20. Specifically, the pressing action of the pressing portion 221 on the second sealing member 123 is conducive to ensuring the fit between the second sealing member 123 and the housing 20, thereby ensuring the sealing effect of the clean cavity.

[0038] Combine Figure 4 As shown, in some embodiments, the second mounting portion 210 has a second connecting portion 211 , and the second connecting portion 211 is used to squeeze and fix the rib 41 together with the first connecting portion 1123 .

[0039] Combine Figure 4 As shown, in some embodiments, a third sealing member 212 is further installed between the rib 41 and the second connecting portion 211, and the rib 41 presses the third sealing member 212 on the inner surface of the second connecting portion 211. It should be noted that the first connecting portion 1123 and the second connecting portion 211 are arranged opposite to each other, and the width of the groove formed by the first mounting portion 112 is consistent with the width of the groove formed by the second mounting portion 210. By keeping the width of the groove structure formed inside the first mounting portion 112 and the second mounting portion 210 consistent, it is beneficial to ensure that the degree of fit between the rib 41 and the first mounting portion 112 and the second mounting portion 210 is consistent, thereby ensuring that the rib 41 can be firmly installed in the mounting groove formed by the first mounting portion 112 and the second mounting portion 210. The convex rib 41 is squeezed by the first connecting portion 1123 and the second connecting portion 211 in the vertical direction at the same time, which limits the relative movement of the convex rib 41 in the above-mentioned installation groove in the vertical direction and increases the pressure of the convex rib 41 on the first sealing member 111, which is conducive to the first sealing member 111 being stably clamped in the first sealing groove 1124 without excessive shaking. At the same time, the first connecting portion 1123 and the second connecting portion 211 squeeze the convex rib 41, thereby ensuring the tightness of the fit between the convex rib 41 and the first sealing member 111, and ensuring the fit between the first sealing member 111 and the first connecting portion 1123, thereby ensuring the sealing effect of the first sealing member 111 on the clean cavity 30, preventing dust from entering the clean cavity 30, and improving the life of the engine.

[0040] It should be noted that when the air filter 10 needs to be inspected and maintained, typically to replace the filter element 60, one only needs to remove the bolts connecting the housing cover 200 to the housing 20 and remove the housing cover 200. This simple structure facilitates easy assembly and disassembly for inspection and maintenance of the air filter 10. When the housing cover 200 is removed, dust on the outside of the housing cover 200 will fall. Due to the provision of the mounting edge 121, most of the falling dust is blocked outside the air filter 10, with a small amount falling into the second sealing groove 124. The second sealing member 123 provided in the second sealing groove 124 prevents dust from entering the first sealing groove 1124 through the second gap 50 between the rib 41 and the second protrusion 1122, thereby ensuring that the second sealing structure effectively seals the second gap 50 between the rib 41 and the second protrusion 1122. Furthermore, compared with the traditional sealing structure (i.e., no second sealing structure is provided), the present application provides a second sealing structure 120, which increases the distance between the rib 41 and the mounting edge 121, thereby facilitating the removal of dust entering the second sealing groove 124. For example, the above-mentioned distance is set to a size sufficient to allow the suction tool used for cleaning to be inserted, thereby avoiding the situation in the traditional sealing structure where dust accumulates in the second gap 50 formed between the rib 41 and the second protrusion 1122 and is difficult to remove.

[0041] In one embodiment, the present application further provides an air filter 10 , comprising the sealing assembly 100 described in any one of the above embodiments.

[0042] In one embodiment, the present application further provides a motorcycle, comprising the air filter 10 described in any one of the above embodiments.

[0043] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
