Detailed Description

Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.

An air filter 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 12. Air filter 100 may be applied to All Terrain vehicles 200 such as ATVs (All Terrain vehicles, also known as All Terrain four-wheeled off-road vehicles). In the following description of the present application, the application of the air filter 100 to an ATV is exemplified. Of course, those skilled in the art will appreciate that air filter 100 may also be applied to other types of vehicles and is not limited to ATVs.

As shown in fig. 1 to 11, an air filter 100 according to an embodiment of the first aspect of the present invention includes a first housing 1 and a second housing 2.

Specifically, be formed with air inlet 111 on the first casing 1, be formed with gas outlet 23 on the second casing 2, second casing 2 establishes the bottom at first casing 1, and second casing 2 and first casing 1 inject the accommodation space that is used for holding filter element 3 jointly, and filter element 3 separates into the accommodation space internally to be located the space 13 before straining of air inlet 111 place one side and be located the space 22 after straining of gas outlet 23 place one side, and filter element 3 is the platelike structure. Here, it should be noted that the "plate-like structure" may be understood as a structure having a thickness smaller (even much smaller) than the other two dimensions (such as length and width). For example, the ratio of the thickness of the filter element 3 to the length or width thereof is 1:3 to 1: 5. Thus, by providing the plate-shaped filter element 3, the thickness of the filter element 3 can be made thinner as compared with the conventional cylindrical filter element 3, so that the height dimension of the air filter 100 is reduced, and the occupied space of the air filter on the all-terrain vehicle 200 such as an ATV can be reduced, which is convenient for arrangement.

Alternatively, the filter insert 3 may be of generally rectangular plate-like configuration as shown in fig. 1 and 2. Of course, the filter insert 3 may also be of a pie-shaped configuration (not shown). It will be appreciated that the particular cross-sectional shape of the filter insert 3 may be specifically arranged according to the actual requirements to better suit the application.

For example, in the example of fig. 1 to 4, the first housing 1 is open at the bottom, the second housing 2 is open at the top, the first housing 1 and the second housing 2 can be fastened to each other to constitute a housing of the air cleaner 100, and a receiving space is defined by the insides of the first housing 1 and the second housing 2 together, and the plate-shaped filter cartridge 3 is disposed in the receiving space. The air inlet 111 may be located at an upper portion of the first housing 1 with the air inlet 111 being separated from the filter cartridge 3 by the pre-filter space 13, and the air outlet 23 may be located at a lower portion of the second housing 2 with the air outlet 23 being separated from the filter cartridge 3 by the post-filter space 22. When the air filter 100 is in operation, an external air flow such as air can enter the accommodating space through the air inlet 111, dust, sand, etc. in the air can be filtered out after being filtered by the filter element 3 in the accommodating space, and the clean air is discharged through the air outlet 23. Because the both sides of filter core 3 have respectively and strain preceding space 13 and strain back space 22, at above-mentioned in-process, the air current that enters into in the accommodation space except discharging through gas outlet 23, other then can stop in straining preceding space 13 and straining back space 22, play the effect of gas storage to can make whole car refuel the reaction faster.

According to the utility model discloses empty filter 100, through the filter core 3 that adopts the platelike structure, compare with the filter core 3 of traditional cylindrical structure, can reduce empty filter 100 occupation space on the thickness direction of filter core 3 relatively, when empty filter 100 is applied to all terrain vehicle 200 such as ATV, can reduce empty filter 100 occupation space on all terrain vehicle 200 such as ATV. Moreover, by dividing the interior of the receiving space into the pre-filter space 13 and the post-filter space 22 on both sides of the filter element 3, the refueling reaction speed of the all-terrain vehicle 200, such as an ATV, can be increased.

According to some embodiments of the present invention, referring to fig. 3 in combination with fig. 4, the first housing 1 includes: a first housing section 11 and a second housing section 12, the first housing section 11 extending from top to bottom obliquely away from the air outlet 23, the first housing section 11 having an air inlet 111 formed therein. The second casing section 12 includes a first section 121 and a second section 122, an upper end of the first section 121 is connected to an upper end of the first casing section 11, a lower end of the first section 121 extends in an inclined manner in a direction away from the first casing section 11, an upper end of the second section 122 is connected to a lower end of the first section 121, the second section 122 extends in a direction away from the first casing section 11 in an inclined manner from top to bottom, the second section 122 is located below the extending direction of the first section 121, the inclined angle of the second section 122 is smaller than that of the first casing section 11, and the second casing section 12, the first casing section 11 and the filter element 3 together define a pre-filter space 13. For example, in the example of fig. 1-4, 9 and 10, the upper end of the first casing section 11 and the upper end of the second casing section 12 are connected to each other, the lower end of the first casing section 11 and the lower end of the second casing section 12 extend obliquely away from each other, respectively, the second casing section 12 includes a first section 121 and a second section 122 that are different in the above-described inclination angle, and the inclination angle of the first casing section 11 is larger than the inclination angle of the first section 121 and the second section 122 of the second casing section 12, and the inclination angle of the first section 121 of the second casing section 12 is smaller than the inclination angle of the second section 122. Here, it should be noted that the "inclination angle" may be understood as an angle between the first section 121 and the second section 122 of the first casing section 11 and the second casing section 12, respectively, and a horizontal plane. Therefore, by providing the first casing 1, the external air can be guided to the filter element 3 through the pre-filter space 13 by the guide of the air inlet 111 of the inclined first casing section 11, thereby improving the filtering efficiency, and since the external air is continuously introduced into the air filter 100, the second casing section 12 having a relatively small inclination angle can make the volume of the pre-filter space 13 large, so that a large amount of air can be stored in the pre-filter space 13 before the air in the accommodating space does not flow through the filter element 3. In addition, by setting the inclination angle of the second section 122 of the second housing section 12 to be larger than the inclination angle of the first section 121, the air flowing to the second section 122 can be guided to the filter cartridge 3 along the surface of the second section 122, so that the air in the pre-filter space 13 can be filtered by the filter cartridge 3.

Further, as shown in fig. 4 and 6, the second housing 2 has at least two housing bottom walls 21 located below the bottom surface of the filter element 3, the at least two housing bottom walls 21 are spaced from each other up and down, and the heights of the at least two housing bottom walls 21 decrease in sequence along the direction from the air inlet 111 to the air outlet 23, a filtered space 22 is defined between the at least two housing bottom walls 21 and the bottom surface of the filter element 3, and the air outlet 23 is located adjacent to the lowest housing bottom wall 21. For example, in the example of fig. 4 and 6, each housing bottom wall 21 is arranged horizontally, and each housing bottom wall 21 is spaced up and down from the bottom surface of the filter cartridge 3 to define a filtered space 22 adapted to store filtered clean air, as oriented in fig. 4, the height of the housing bottom walls 21 is reduced in turn in a direction from the left air inlet 111 toward the right air outlet 23, and adjacent two housing bottom walls 21 are connected to each other, and the air outlets 23 are formed on the side wall 252 adjacent to the lowest housing bottom wall 21. Therefore, by arranging the second housing 2, air in the filtered space 22 can flow to the air outlet 23 well while ensuring that the filtered space 22 realizes a good storage function.

Three housing bottom walls 21 are shown in fig. 4 for illustrative purposes, but it is obvious to those skilled in the art after reading the technical solution of the present application that the solution can be applied to other number of housing bottom walls 21, which also falls into the protection scope of the present invention.

According to some embodiments of the present invention, referring to fig. 1, 2 and 6, the top of the second housing 2 is open, two step portions 24 are provided in the second housing 2, the two step portions 24 are provided on two side walls 252 of the second housing 2 opposite to each other, the upper surfaces of the two step portions 24 are adapted to support the bottom surface of the filter element 3, one of the two step portions 24 having a larger width is opposite to the air inlet 111, and the portion of the filter element 3 corresponding to the post-filter space 22 is opposite to the air outlet 23. From this, through set up two step portions 24 relative to each other in the casing, two step portions 24 can play fine supporting role to filter core 3, and filter core 3 is difficult for appearing the condition such as deformation after long-time the use to the filter effect of empty filter 100 has been guaranteed. Moreover, by arranging that the wider one of the two steps 24 is opposite to the air inlet 111, for example, the width of the left step 24 is greater than the width of the right step 24 in fig. 6, the portion of the filter element 3 corresponding to the filtered space 22 is opposite to the air outlet 23, and at this time, the air outlet 23 corresponds to the portion of the filter element 3 not supported by the steps 24, so that after the outside air enters the accommodating space through the air inlet 111, the outside air can be filtered at the portion of the filter element 3 corresponding to the wider one of the two steps 24, and then flows to the portion of the filter element 3 corresponding to the air outlet 23 and is filtered again, thereby improving the filtering effect.

Alternatively, each step portion 24 is formed by a portion of the outer wall surface of the second housing 2 being recessed inward, as shown in fig. 1, 2, 6, 9, and 10. Therefore, while the good supporting effect is ensured, the material consumption of the air filter 100 can be saved, the cost is saved, and the occupied space of the air filter 100 can be further reduced.

Here, it should be noted that the direction "outside" may be understood as a direction toward the center of the second housing 2, and the opposite direction is defined as "inside", i.e., a direction away from the center of the second housing 2. From this, compress tightly portion 14 and hold the tank part 25 through the setting and fix a position the extension limit of filter core 3 in holding tank part 25 for the air that enters into in the accommodation space all can flow to air outlet 23 after filter core 3 filters, has effectively guaranteed the filter effect of empty filter 100, and whole simple structure, simple to operate, the location is accurate.

According to some embodiments of the present invention, as shown in fig. 1-3 and 6-10, one side of the first casing 1 and the second casing 2 is positioned by a plurality of card insertion structures arranged at intervals, and the other side of the first casing 1 and the second casing 2 is locked by a plurality of locking structures arranged at intervals. In the description of the present invention, "a plurality" means two or more. For example, two card insertion structures and two latch structures are respectively shown in the examples of fig. 1 to 3 and 6 to 10, the two card insertion structures and the two latch structures are respectively located at four corners of the first housing 1 and the second housing 2, and the two card insertion structures and the two latch structures are respectively located at both sides of the air inlet 111 and the air outlet 23. During installation, the first shell 1 and the second shell 2 can be positioned through a plurality of card inserting structures to realize the preassembly of the first shell 1 and the second shell 2, and then the first shell 1 and the second shell 2 are locked through a plurality of lock catch structures to ensure that the first shell 1 and the second shell 2 are assembled; when the locking device is disassembled, the locking structures can be unlocked firstly, and then the locking structures are separated from the matching, so that the locking device is convenient to assemble and disassemble and is high in assembling and disassembling efficiency.

Here, it is to be understood that "the middle portion of the handle portion 161" herein should be interpreted broadly, i.e., a portion located between both ends of the handle portion 161, not limited to only the center in the longitudinal direction of the handle portion 161. A second locking member having a locking portion 271 extending vertically downward and spaced apart from the outer surface of the second housing 2 is attached to the bottom of the accommodating groove portion 25, the handle portion 161 bringing a free end (e.g., a lower end in fig. 11) of the locking portion 162 to abut on a side surface of the locking portion 271 adjacent to the center of the second housing 2 when the other end of the handle portion 161 is dialed upward, the handle portion 161 bringing the free end of the locking portion 162 to be separated from a side surface of the locking portion 271 adjacent to the center of the second housing 2 when the other end of the handle portion 161 is dialed downward. The locking portion 162 may include two arc-shaped segments respectively provided at both sides of the handle portion 161, a pivot segment having both ends connected to upper ends of the two arc-shaped segments, respectively, the pivot segment passing through a middle portion of the handle portion 161 and being pivotable with respect to the handle portion 161, and a stopper segment connected between lower ends of the two arc-shaped segments. When assembling, the above-mentioned other end of the handle 161 can be pulled clockwise as shown in fig. 10, so that the locking portion 162 moves upward to make the lower end (i.e. the above-mentioned abutting section) of the locking portion 271 of the second locking member abut against the side surface of the locking portion 271 facing the center of the second housing 2, thereby achieving locking, and the lower end of the locking portion 271 is located between the two arc-shaped sections of the locking portion 162; when detaching, the other end of the handle 161 is pulled in a counterclockwise direction as viewed in fig. 10, so that the locking portion 162 moves downward to disengage the lower end (i.e., the abutting section) thereof from the locking portion 271 of the second locking member. When both the arc-shaped segment and the abutting segment of the locking portion 162 are rotated to the side of the locking portion 271 away from the center of the second housing 2, the first housing 1 can be removed from the second housing 2. This makes it possible to attach and detach the first casing 1 and the second casing 2 very easily. Alternatively, the locking portion 162 may be a steel (e.g., spring steel, etc.) locking hook as shown in fig. 10 and 11. But is not limited thereto.
