[0042] The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0043] Embodiment 1

[0044] The present embodiment relates to an air filter housing, which is particularly suitable for an air filter used in an environment with a lot of sand and dust, so that the air filter can efficiently remove the sand and dust accumulated in the housing and maintain smooth air circulation, thereby ensuring the normal operation of the engine and improving the overall off-road performance of the vehicle.

[0045] Based on the above design concept, an exemplary structure of the air filter housing of this embodiment is as follows: Figures 1 to 3 As shown, in terms of overall structure, the air filter housing mainly includes a housing body 1, a housing chamber 102 is provided in the housing body 1, the housing chamber 102 is used to accommodate the filter element of the air filter, a dust collecting portion 1014 is provided at the bottom of the housing chamber 102, an opening 1013 connected to the space inside the dust collecting portion 1014, and a blocking member 2 capable of covering the opening 1013 is provided on the housing body 1.

[0046] It should be noted that Figures 1 to 3 The air filter housing is a schematic diagram of the structure of the lower housing. It should be understood that no matter the air filter housing is the lower housing or the entire housing, the dust collecting part 1014, the opening 1013 and the blocking member 2 are arranged at the bottom thereof, which facilitates the realization of the dust removal function.

[0047] In order to facilitate the discharge of sand and dust from the opening 1013, as a preferred embodiment, a partition 3 is provided in the accommodating chamber 102, and the partition 3 can be fixed in the accommodating chamber 102 by bonding, screwing, clamping, etc., and its structural schematic diagram can be referred to Figure 2 and Figure 5 As shown. The partition 3 is placed above the sand and dust collecting part 1014, and the partition 3 is covered with a plurality of through holes 301 to block large sand and gravel. As in this embodiment, the through holes 301 can be directly formed on the partition 3, or can be formed by the partition 3 and the wall of the accommodating chamber 102, such as the side wall 108 or the bottom wall 101.

[0048] It should be noted that the partition 3 provided in this embodiment can facilitate the screening of larger particles of impurities, that is, only smaller particles of dust are allowed to enter the dust collecting part 1014 from the through hole 301, thereby preventing larger particles of impurities from blocking the opening 1013 and affecting the removal of dust.

[0049] Still refer to Figure 5As shown, the through holes 301 are circular holes, and multiple through holes 301 are evenly arranged, which is convenient for processing. It should be noted that, in addition to being circular holes, the through holes 301 can also be square holes, diamond holes, triangular holes, etc., and multiple through holes 301 can also be unevenly distributed, which can also play the role of only allowing small particle sand and dust to pass through the through holes 301 while blocking large particle sand and gravel. The diameter of the through holes 301 is set according to actual needs and is not specifically limited in this embodiment.

[0050] In order to improve the structural strength of the housing body 1, as a preferred implementation manner, multiple reinforcing ribs are provided on the outer side of at least one side wall 108 of the housing body 1. For example, in this embodiment, multiple reinforcing ribs are provided on the outer sides of the four side walls 108 of the housing, and multiple reinforcing ribs are all arranged close to the opening at the upper part of the accommodation cavity 102, so as to preferably improve the structural strength of the housing body 1.

[0051] In a preferred implementation manner, multiple reinforcing ribs on each side all include a plurality of transverse reinforcing ribs 103 and a plurality of longitudinal reinforcing ribs 104, and the plurality of transverse reinforcing ribs 103 and the plurality of longitudinal reinforcing ribs 104 intersect to form a grid shape, so as to preferably improve the structural strength of the housing body 1.

[0052] It should be understood that, in addition to including transverse reinforcing ribs 103 and longitudinal reinforcing ribs 104, the reinforcing ribs can also include inclined reinforcing ribs, and the arrangement manner of multiple reinforcing ribs can also be other ways, such as setting the reinforcing ribs in a wavy line shape, or only including one of the transverse reinforcing ribs 103 and the longitudinal reinforcing ribs, which is also acceptable as long as the structural strength of the air filter housing can be ensured.

[0053] In order to facilitate the collection of sand and dust, as a preferred implementation manner, the aforementioned sand and dust collection part 1014 is specifically formed by a part of the bottom wall 101 of the accommodation cavity 102 being lower than other parts. Here, it should be noted that being lower than other parts means that Figure 3 and Figure 4 in the up and down directions shown, the part of the bottom wall 101 where the sand and dust collection part 1014 is provided is arranged lower than other parts.

[0054] Specifically in this embodiment, the bottom wall 101 includes an inclined first inclined plate 1011 and a second inclined plate 1012, and the sand and dust collection part 1014 is located at a lower position at the intersection of the first inclined plate 1011 and the second inclined plate 1012. In the above structure, the bottom wall 101 includes the first inclined plate 1011 and the second inclined plate 1012, and the sand and dust collection part 1014 is located at a lower position at the intersection of the first inclined plate 1011 and the second inclined plate 1012, which is beneficial for sand and dust and other impurities on the bottom wall 101 to flow into the sand and dust collection part 1014 under the action of gravity. It should be noted that here, the lower position at the intersection of the first inclined plate 1011 and the second inclined plate 1012 means that, in Figure 3 andFigure 4 At a position below the intersection of the first inclined plate 1011 and the second inclined plate 1012 in the up-down direction shown.

[0055] In a preferred embodiment, the aforementioned opening 1013 is located at the lowest position of the intersection of the first inclined plate 1011 and the second inclined plate 1012, so as to facilitate the automatic flow of the dust accumulated in the dust collection part 1014 towards the opening 1013 under the action of gravity.

[0056] It should be noted that, as a preferred embodiment, the housing body 1 includes an upper housing body and a lower housing body arranged up and down, the upper housing body and the lower housing body are detachably connected, and the lower housing body is provided with a dust collection part 1014, an opening 1013 and a blocking member 2. With such a setting, the upper housing body and the lower housing body are detachably connected, which is convenient for assembly and disassembly and is also convenient for replacing the filter element.

[0057] However, it should be understood that the air filter housing in this embodiment can be either the entire air filter housing including the upper housing body and the lower housing body, or the lower housing of the air filter. For example Figures 1 to 3 The structure shown in is an exemplary structure of a lower housing. A plurality of clamping parts 105 are circumferentially spaced at the upper open part of the lower housing body to facilitate connection with the upper housing body not shown in the figure.

[0058] In this embodiment, the number of the clamping parts 105 is five. It can be understood that it is also feasible when the number of the clamping parts 105 is other values. In addition, in this embodiment, the shapes of the clamping parts 105 on both sides of the open part can be the same or different. Specifically, the existing clamping structure can be referred to, as long as it is convenient for the upper housing body and the lower housing body to be clamped and connected.

[0059] Still referring to Figure 1 As shown, a first mounting part 106 is provided on one side of the housing body 1. The first mounting part 106 is preferably an insertion post, which is used to be inserted into a sleeve on the vehicle body so as to facilitate the installation of the air filter on the vehicle body.

[0060] Relative to the side where the first mounting part 106 is provided, a second mounting part 107 is provided on the other side of the housing body 1. In this embodiment, the second mounting part 107 is specifically a convex post protruding outwards, and a connection hole is provided in the convex post. In this way, a heat insulation part not shown in the figure can be connected to the connection hole through a connecting member passing through itself, and the heat insulation part is installed on the housing body 1.

[0061] In addition, when the air filter housing is an integral air filter housing, it may further include a left housing body and a right housing body arranged left and right. The left housing body and the right housing body are detachably connected to facilitate the installation and removal of the filter element. At this time, the aforementioned bottom wall 101 may be formed by splicing the left bottom wall of the left housing body and the right bottom wall of the right housing body, and the aforementioned dust collection part 1014, opening 1013, and partition 3 may also be formed by splicing.

[0062] As Figure 3 and Figure 6 shown, as a preferred embodiment, an air flow inlet 1015 communicating with the accommodation chamber 102 is provided on the housing body 1. The air flow inlet 1015 and the dust collection part 1014 are arranged close to both sides of the housing body 1. In the state shown in Figure 2 , the dust collection part 1014 is located at the lower left corner of the housing body 1, and the dust collection part 1014 is located at the upper right corner of the housing body 1. In this way, arranging the air flow inlet 1015 and the dust collection part 1014 close to both sides of the housing body 1 facilitates dust collection and overall layout.

[0063] Still referring to Figure 6 shown, in order to facilitate the introduction of fresh air, an intake pipe 4 is installed at the air flow inlet 1015. In this embodiment, a partition part 5 is provided in the intake pipe 4. The partition part 5 is used to block impurities in the air flow, and there are air passages on the partition part 5 for the air flow to pass through. It should be noted that the partition part 5 is preferably in a plate-like structure, and the air passages are preferably multiple and are densely distributed on the partition part 5, which can better balance the dual functions of air intake and impurity blocking.

[0064] Here, it should be noted that the air passages are multiple and are densely distributed on the partition part 5, which means that there are multiple air passages arranged on the partition part 5. The multiple air passages can be evenly arranged or unevenly arranged. Specifically in this embodiment, the partition part 5 is in a plate-like structure, and the air passages are ventilation holes, and the ventilation holes are basically densely distributed on the partition part 5, having a good ventilation effect.

[0065] Continuing to refer to Figure 6 shown, preferably, the partition part 5 gradually inclines upward in a direction away from the air flow inlet 1015, so that the blocked impurities can fall onto the horizontal section of the intake pipe 4 directly connected to the air flow inlet 1015.

[0066] In order to facilitate the discharge of accumulated dust, preferably, a dust removal part 6 is provided at the bottom of the intake pipe 4. The dust removal part 6 is close to the connection position of the partition part 5 and the intake pipe 4. An opening communicating with the inner cavity of the intake pipe 4 is provided at the bottom of the intake pipe 4, and the dust removal part 6 is arranged at the opening to facilitate the removal of the impurities blocked by the partition part 5.

[0067] In the above structure, a separating part 5 and a dust removing part 6 are arranged on the air inlet pipe 4. Among them, the separating part 5 is used to block impurities, and the dust removing part 6 is used to remove the impurities blocked by the separating part 5, which further helps to keep the air circulation smooth and can extend the service life of the filter element.

[0068] As a preferred embodiment, the aforementioned dust removing part 6 includes a dust removing housing 601 formed with a receiving groove and a normally closed valve 602. The receiving groove communicates with the aforementioned opening and thus with the lumen of the air inlet pipe 4. A notch is provided at the bottom of the receiving groove. The normally closed valve 602 is arranged at the notch at the bottom of the receiving groove, and the normally closed valve 602 is opened by gas pressure or gravity. Here, the gravity can come from accumulated dust and other impurities, for example. By arranging the normally closed valve 602 here, it is beneficial to automatically remove the impurities in the receiving groove without manual cleaning.

[0069] Finally, it should be noted that, also for the convenience of automatically removing the dust in the dust collection part 1014, as a preferred embodiment, the opening 1013 is arranged on the side wall 108 of the housing body 1 and communicates with the lowest position in the dust collection part 1014. The blocking member 2 is located outside the side wall 108 provided with the opening 1013, and the blocking member 2 is used to discharge the dust in the dust collection part 1014. In this way, there is no need to manually remove the dust, saving labor.

[0070] In order to further facilitate the removal of dust, as a preferred embodiment, the blocking member 2 of this embodiment includes a Venturi tube. The negative pressure inlet 201 of the Venturi tube communicates with the opening 1013. The fluid inlet 202 of the Venturi tube is used to communicate with an air compressor, and the fluid outlet 203 communicates with the atmosphere, having a good technical effect of automatically removing dust.

[0071] For the convenience of understanding, it should be noted that the working principle of the Venturi tube is as follows: when the compressed air flows through the narrow part, the speed increases and the pressure decreases, forming a negative pressure area. When the air flow sprays out from the nozzle, the surrounding ambient air is sucked in and accelerated to mix, forming a strong suction force. This force is sufficient to effectively suck up the dust particles accumulated in the dust collection part 1014 and spray them out at high speed, thus realizing dust cleaning.

[0072] It should also be noted that in this embodiment, the blocking member 2 can be other structures in addition to the Venturi tube, such as the aforementioned dust removing part 6. Only at this time, the opening 1013 needs to be arranged on the bottom wall 101 of the housing body 1, which is easy to achieve an excellent effect of automatically removing dust.

[0073] In addition, the negative pressure inlet 201 of the aforementioned Venturi tube can be welded to the opening 1013, for example. In addition to this, it is also possible to use methods such as flange connection, snap connection, and plug connection. In order to facilitate the stable installation of the Venturi tube, a mounting bracket or a reinforcing structure that improves the structural strength of the connection part between the Venturi tube and the housing body 1 also belongs to the housing. In addition, the blocking member 2 can be a plug cover in addition to the Venturi tube. At this time, the plug cover is preferably detachably connected to the opening 1013 to facilitate the manual removal of impurities such as dust at regular intervals.

[0074] In the air filter housing of this embodiment, by providing a dust collection part 1014 on the bottom wall 101 of the accommodation cavity 102, it is convenient to collect the dust that has fallen onto the bottom wall 101. An opening 1013 is provided and a blocking member 2 is provided to facilitate the cleaning of dust. Moreover, the blocking member 2 can cover the opening 1013 without affecting the air filtering function of the air filter housing, facilitating the smooth flow of air, thereby ensuring the normal operation of the engine and improving the off-road performance of the vehicle.
