Abstract

The present invention discloses an air filter and a vehicle. The air filter comprises: a shell, wherein the shell has a first space and a second space; a guide member, wherein the guide member has an airflow space and is arranged in the first space, wherein the airflow space is connected to the second space and the air outlet, wherein the first space has an airflow channel connected to the air inlet and the second space, wherein the airflow channel is arranged around the guide member along the circumference of the guide member; and a filter member, wherein the filter member is arranged in the airflow space. Thus, by arranging the filter member in the guide member, the airflow at the air inlet cannot directly contact the filter member, thereby preventing dust from accumulating in the filter member and increasing the dust capacity of the air filter. By arranging the guide member, the inlet and outlet directions of the airflow passing through the filter member are parallel or coaxial, thereby enabling the air filter to be adapted to a direct-flow filter element without changing the shell structure, thereby increasing the dust capacity of the air filter, reducing the air intake resistance, increasing the service life of the air filter, and reducing the weight of the air filter.

[0033] Reference below Figure 1-Figure 5 An air cleaner 100 according to an embodiment of the present invention will be described.

[0034] Reference Figure 1 The air filter 100 according to the embodiment of the present invention comprises: a housing 110, a guide member 120 and a filter member. The housing 110 has a first space 111 and a second space 112, the housing 110 has an air inlet 113 and an air outlet 114, the guide member 120 has an airflow space 121 and is arranged in the first space 111, the airflow space 121 is connected to the second space 112 and the air outlet 114, the first space 111 has an airflow channel 122 connected to the air inlet 113 and the second space 112, the airflow channel 122 is arranged around the guide member 120 along the circumference of the guide member 120, and the filter member is arranged in the airflow space 121.

[0035] Specifically, refer to Figure 1The air filter 100 may be configured as a cylinder, the air outlet 114 may be disposed at the top of the housing 110, the air inlet 113 may be disposed at one end of the housing 110 close to the air outlet 114, and the second space 112 is disposed at a side of the housing 110 away from the air outlet 114. The airflow enters the first space 111 through the air inlet 113, the first space 111 is provided with a guide 120, the airflow channel 122 is disposed around the circumferential outer side of the guide 120, and the air inlet 113 is connected to the airflow channel 122, the airflow channel 122 may guide the flow direction of the airflow, and the airflow enters the first space 111 and flows along the airflow channel 122, the airflow channel 122 is connected to the second space 112, so that the airflow can flow along the airflow channel 122 to the second space 112, and the airflow can rotate in the second space 112.

[0036] Further integration Figure 2 and Figure 3 The airflow space 121 is arranged inside the guide member 120, and the filter member is arranged inside the guide member 120. The guide member 120 can block the filter member so that the airflow at the air inlet 113 cannot directly contact the filter member, thereby preventing dust from accumulating in the filter member, increasing the dust holding capacity of the air filter 100, and increasing the service life of the air filter 100.

[0037] In the related art, the air inlet and filter element of a conventional cylindrical single-stage air filter are arranged relative to each other, so that the airflow at the air inlet is directly blown into the filter element, causing most of the dust to accumulate in the filter element, making it difficult to significantly increase the dust capacity of the air filter without changing the filter element, resulting in a shorter life of the filter element.

[0038] The present application arranges the filter element in the guide element 120, and the guide element 120 can be used to shield the filter element, so that the airflow at the air inlet 113 cannot directly contact the filter element, thereby preventing dust from accumulating in the filter element, increasing the dust holding capacity of the air filter 100, and increasing the service life of the air filter 100.

[0039] Furthermore, the airflow space 121 is respectively connected to the second space 112 and the air outlet 114. The filter element is arranged in the airflow space 121, and the air outlet 114 can generate suction on the airflow, so that the airflow rotating in the second space 112 can flow upward in the axial direction to vertically pass through the filter element. The inlet and outlet directions of the airflow through the filter element are parallel or coaxial, so that the air filter 100 can be adapted to a direct-flow filter element without changing the structure of the outer shell 110, so as to increase the ash holding capacity of the air filter 100, reduce the intake resistance, increase the service life of the air filter 100, and also reduce the weight of the air filter 100.

[0040] In the related art, the air inlet and outlet of the cylindrical air filter are usually arranged vertically in the axial direction, so that the air flow direction entering the air filter is perpendicular to the air flow direction flowing out of the air filter, resulting in the cylindrical air filter being unable to adapt to the direct flow filter element. The conventionally used cylindrical paper filter element has low coarse filtration efficiency, and the cylindrical paper filter element has a short service life in a dusty environment.

[0041] The present application sets a guide member 120 in the air filter 100 so that the inlet and outlet directions of the airflow passing through the filter element are parallel or coaxial, so that the filter element can be constructed as a direct-flow filter element, so that the air filter 100 can be adapted to the direct-flow filter element without changing the structure of the outer shell 110, so as to increase the dust holding capacity of the air filter 100, reduce the intake resistance, increase the service life of the air filter 100, and also reduce the weight of the air filter 100.

[0042] According to the air filter 100 of the present invention, by arranging the filter element in the guide element 120, the guide element 120 can be used to shield the filter element, so that the airflow at the air inlet 113 cannot directly contact the filter element, prevent dust from accumulating in the filter element, and improve the dust holding capacity of the air filter 100. By arranging the guide element 120, the inlet and outlet directions of the airflow passing through the filter element are parallel or coaxial, so that the air filter 100 can be adapted to the direct flow filter element without changing the structure of the housing 110, so as to improve the dust holding capacity of the air filter 100, reduce the intake resistance, and increase the service life of the air filter 100, and the weight of the air filter 100 can also be reduced.

[0047] Furthermore, the air inlet 113 and the channel inlet are arranged opposite to each other in the radial direction, and the channel inlet is communicated with the air inlet 113, so that the airflow can flow into the airflow channel 122 through the channel inlet after passing through the air inlet 113, and a channel outlet 1221 is provided on the first flange 123, and the channel outlet 1221 and the second space 112 are arranged opposite to each other in the axial direction, and the channel outlet 1221 is communicated with the second space 112, so that the airflow channel 122 can be connected with the second space 112, and the airflow can flow from the airflow channel 122 to the second space 112 through the channel outlet 1221, so that the airflow can flow from the airflow channel 122 to the second space 112, so that the airflow can flow from the air inlet 113 into the second space 112.

[0048] In addition, the first flange 123 can also improve the structural strength of the guide member 120 and prevent the guide member 120 from being deformed.

[0049] In some embodiments of the present invention, the housing 110 or the air guide 120 defines an air flow channel 122 .

[0050] Specifically, Figure 1 In the illustrated embodiment, at least a portion of the guide member 120 may be spaced apart from the housing 110 in the radial direction, so that the housing 110 and the guide member 120 together define an air flow channel 122 , and gas may flow in the air flow channel 122 .

[0052] Similarly, the guide member 120 can fit together with the inner wall of the outer shell 110, and a side wall surface of the outer shell 110 opposite to the guide member 120 can be provided with a groove structure arranged in the circumference of the outer shell 110 to form an airflow channel, the groove structure extends in the axial direction, and the position where the groove structure is connected to the air inlet 113 is constructed as a channel inlet, and the position where the groove structure is arranged opposite to the second space 112 is constructed as a channel outlet, so that the airflow channel 122 can be respectively connected to the air inlet 113 and the second space 112.

One end of the guide flange 124 away from the air inlet 113 is provided at the position of the channel outlet 1221, and the guide flange 124 can guide the airflow, so that the airflow can flow along the airflow channel 122, and the airflow can flow into the second space 112 through the channel outlet 1221.

[0054] Further references Figure 1 The guide flange 124 can be engaged with the inner wall of the housing 110 to seal the airflow channel 122 so that the airflow flows in one direction along the airflow channel 122 to prevent airflow convection.

[0055] Optionally, the first flange 123 and the flow-guiding flange 124 may both be constructed as a flange structure having elasticity to improve the sealing effect of the first flange 123 and the flow-guiding flange 124 .

[0057] Specifically, the airflow flowing into the second space 112 can flow into the airflow space 121 through the first open end, and a filter element is provided in the airflow space 121. The airflow can pass through the filter element to realize the filtering effect of the filter element on the airflow. The filtered airflow can flow to the air outlet 114 through the second open end 1211, and can be discharged to the outside through the air outlet 114, thereby realizing the filtering effect of the air filter 100 on the airflow.

[0058] In some embodiments of the present invention, a side wall of the housing 110 has an air inlet 113 .

[0059] Specifically, Figure 1 As shown, the air inlet 113 can be formed on the radial outer side of the side wall, and one end of the air inlet 113 is connected to the channel inlet, and the end of the air inlet 113 facing away from the guide member 120 is connected to the outside world. The external gas can flow into the airflow channel 122 through the air inlet 113 and the channel inlet. The guide flange 124 can guide the gas entering the airflow channel 122.

[0060] Furthermore, the airflow space 121 is connected with the second space 112 through the first open end, and the airflow space 121 is connected with the air outlet 114 through the second open end 1211, so that the air outlet 114, the airflow space 121 and the second space 112 are connected, and the air outlet 114 can generate suction on the airflow in the second space 112, thereby driving the airflow in the second space 112 to flow upward in the axial direction, and the airflow flows into the airflow space 121 through the first open end. A filter element is provided in the airflow space 121, and the airflow can pass through the filter element. The airflow passing through the filter element can flow to the air outlet 114 through the second open end 1211, and can be discharged to the outside through the air outlet 114, thereby, the airflow can be finely filtered through the filter element.

[0061] like Figure 1 As shown, in some embodiments of the present invention, the air filter 100 further includes a support frame 130 , the first space 111 and the second space 112 are adjacent, and the support frame 130 is disposed in the second space 112 and supports the guide element 120 or the filter element.

[0062] Specifically, combined Figure 1 and Figure 2 The guide member 120 is arranged in the first space 111, the first space 111 is arranged above the second space 112 in the axial direction, the support frame 130 is arranged in the second space 112, the support frame 130 and the guide member 120 are arranged opposite to each other in the vertical direction, and the support frame 130 can support the guide member 120 in the axial direction to arrange the guide member 120 in the first space 111, so that the channel inlet can be arranged opposite to the air inlet 113.

[0063] Optionally, the filter element can be fixedly connected to the guide element 120 to improve the assembly reliability of the filter element, and the support frame 130 can indirectly support the filter element while supporting the guide element 120. The filter element can also be directly arranged at one end of the airflow space 121 close to the support frame 130, and the support frame 130 can support the guide element 120 in the axial direction, and the support frame 130 can also support the filter element, so that the assembly of the air filter 100 is convenient.

[0064] Combination Figure 2 , Figure 4 and Figure 5 In some embodiments of the present invention, the support frame 130 includes: a mounting seat 131 and a support portion 132, the mounting seat 131 abuts against the inner wall of the second space 112, and the support portion 132 is fixedly disposed on the mounting seat 131 and supports the guide member 120 or the filter member.

[0065] Specifically, the mounting seat 131 is arranged on a side of the second space 112 away from the first space 111, and the mounting seat 131 is abutted against the inner wall of the second space 112, that is, the mounting seat 131 is embedded in the outer shell 110 so that the mounting seat 131 can be fixed in the outer shell 110, and the mounting seat 131 and the supporting portion 132 are arranged opposite to each other in the axial direction, and the mounting portion and the supporting portion 132 are fixedly connected, so that the support frame 130 can be fixed in the outer shell 110.

[0066] Further references Figure 1 The support portion 132 is disposed on one side of the second space 112 close to the first space 111 , and the support portion 132 is disposed opposite to the flow guide 120 and the filter in the axial direction, and the support portion 132 can support the flow guide 120 and the filter in the vertical direction.

[0067] In other embodiments of the present invention, Figure 1 In the illustrated embodiment, a limiting groove 116 extending upward in the axial direction is provided on the bottom wall 117 of the housing 110, and the mounting seat 131 can be engaged with the side wall of the limiting groove 116, that is, the mounting seat 131 can be embedded in the limiting groove 116 to fix the mounting seat 131.

[0068] In some embodiments of the present invention, a third space 115 is formed between the mounting seat 131 and the inner wall of the second space 112 , and the mounting seat 131 has a material through hole 1311 communicating with the third space 115 .

[0069] Specifically, combined Figure 1 , Figure 4 and Figure 5 A support plate 135 may be provided on one side surface of the mounting seat 131 facing away from the guide member 120, and the support plate 135 may support the mounting seat 131 in the axial direction to space the mounting seat 131 from the bottom wall 117 of the outer shell 110, so that a third space 115 is defined between the mounting seat 131 and the inner wall of the outer shell 110, and the third space 115 is arranged opposite to the second space 112 in the axial direction, and the third space 115 is arranged at one end of the outer shell 110 away from the air outlet 114, and the material through hole 1311 may be connected to the third space 115.

[0070] Optionally, the support plate 135 can be constructed as a rectangular plate structure, and multiple support plates 135 can be provided. Multiple support plates 135 can ensure the assembly stability of the mounting seat 131. It can be understood that the support plate 135 can only play a supporting role, and the shape and number of the support plate 135 are not specifically limited.

[0071] Among them, Figure 4 As shown, the mounting seat 131 may be provided with a through hole structure penetrating the mounting plate to form a material through hole 1311; Figure 4 and Figure 5 A side surface of the mounting seat 131 facing away from the guide member 120 may be provided with an enclosure extending toward the third space 115, the enclosure defining a through-hole structure, and a hole structure opposite to the through-hole structure is provided on the mounting seat 131, so that the mounting plate and the enclosure jointly define a material through hole 1311.

[0072] It should be noted that if Figure 1 As shown, the radial dimension of the first space 111 is smaller than the radial dimension of the second space 112. When the airflow flows from the airflow channel 122 into the second space 112, the space dimension becomes larger, resulting in a sudden decrease in the velocity of the airflow, and the large-sized particles in the airflow fall on the mounting seat 131 due to inertia. Part of the large-sized particles that fall can directly fall into the third space 115 through the material through hole 1311, and the remaining large-sized particles that fall on the mounting seat 131 can fall into the third space 115 through the material through hole 1311 due to vibration, etc., thereby achieving coarse filtration of the airflow and enabling the support frame 130 to have a dust collection function.

[0073] Therefore, external gas can flow into the airflow channel 122 through the air inlet 113 and the channel inlet, and the guide flange 124 can guide the gas entering the airflow channel 122, so that the airflow can flow along the airflow channel 122 through the channel outlet 1221 to the second space 112, and rotate and flow in the second space 112.

[0074] When the airflow flows from the airflow channel 122 into the second space 112, the space size becomes larger, resulting in a sudden decrease in the flow rate of the airflow, and the large-sized particles in the airflow fall on the mounting seat 131 due to inertia. Part of the fallen large-sized particles can directly fall into the third space 115 through the material through hole 1311, and the remaining large-sized particles that fall on the mounting seat 131 can fall into the third space 115 through the material through hole 1311 due to vibration, etc., thereby achieving coarse filtration of the airflow, that is, primary filtration.

[0075] The air outlet 114, the air flow space 121 and the second space 112 are connected and arranged, the air outlet 114 can generate suction to the air flow in the second space 112, thereby driving the air flow in the second space 112 to flow upward in the axial direction, and the air flow flows into the air flow space 121 through the first open end, and a filter element is arranged in the air flow space 121, so that the air flow can pass through the filter element, and the air flow passing through the filter element can flow to the air outlet 114 through the second open end 1211, and can be discharged to the outside through the air outlet 114, thereby, the air flow can be finely filtered, that is, secondary filtering, through the filter element, so that the single-stage air filter can be upgraded to a double-stage filtering air filter 100 without changing the original single-stage air filter shell structure, that is, the original single-stage cylindrical air filter can be upgraded to a double-stage filtering air filter 100, that is, the original single-stage cylindrical air filter can be upgraded to a double-stage filtering air filter 100, thereby improving the filtering efficiency of the air filter 100, reducing the dust entering the filter element, and improving the service life of the air filter 100.
