Description

Technical Field

[0001] This application relates to the field of vehicle air intake technology, and particularly to an air intake system and a vehicle equipped with it. Background Technology

[0002] Currently, the cleanliness of the engine's intake system directly determines its performance and lifespan, primarily relying on the air filter as the core filtration component. However, when the air filter fails to seal or operates under overload, dust can easily enter the combustion chamber through the bypass valve or damaged filter media, resulting in poor intake air cleanliness and negatively impacting engine performance. Utility Model Content

[0003] In view of this, this application aims to provide an air intake system that has a better dust removal effect and can improve the cleanliness of the intake air.

[0004] To achieve the above objectives, the technical solution of this application is implemented as follows: An air intake system is adapted to be disposed at the air intake end of an air-using component, including an air intake pipe and a dust removal unit disposed on the air intake pipe; The dust removal unit includes a plurality of first guide plates arranged sequentially along the direction of the airflow, and a dust collection box disposed at the bottom of each of the first guide plates. Each of the first guide vanes is located inside the air intake pipe, at least a portion of the dust collection box is located outside the air intake pipe, and the dust collection box is detachably mounted on the air intake pipe.

[0005] Furthermore, the dust removal unit also includes a plurality of second guide plates arranged sequentially in the air intake pipe along the direction of the air intake airflow; In the vertical direction of the vehicle, the second air deflector is located above the first air deflector, and a channel is formed between the first air deflector and the second air deflector, the channel for the intake airflow to pass through.

[0006] Furthermore, along the direction of the intake airflow, the first guide plate is inclined from bottom to top toward the outlet end of the intake pipe, and the second guide plate is inclined from top to bottom toward the outlet end of the intake pipe. The projection of the second air deflector onto the first air deflector in the vertical direction of the vehicle is at least partially overlapping.

[0007] Furthermore, the projection portions of the first guide vane and the second guide vane overlap in the direction of the intake airflow.

[0008] Furthermore, at least one of the first guide plates is provided with a plurality of first guide vanes spaced apart, each first guide vane extending along the inclined direction of the first guide plate; and / or, At least one of the second guide plates is provided with a plurality of second guide vanes spaced apart, each of the second guide vanes extending along the inclined direction of the second guide plate.

[0009] Furthermore, at least one of the second guide plates has a plurality of vent holes at one end away from the first guide plate, and each of the vent holes is used to allow the intake airflow to pass through.

[0010] Furthermore, it also includes an air filter located at the air outlet end of the air intake pipe; The air filter housing has a dust discharge port at the bottom and a blocking plate at the bottom of the dust discharge port, with a gap between the blocking plate and the housing that allows communication with the outside.

[0011] Furthermore, the bottom of the housing is provided with an arched portion that arches into the housing, and a protruding ring provided around the arched portion, the protruding ring protruding outward from the housing; The dust outlet is located on the arched portion, and the blocking plate includes a rod inserted into the arched portion and a plate located at the bottom of the rod. The gap is located between the plate and the protruding ring.

[0012] Furthermore, the plate is conical; and / or, The dust outlet is an arc shape arranged along the circumference of the rod.

[0013] Compared with related technologies, this application has the following advantages: (1) The air intake system described in this application, by setting a dust removal unit on the air intake pipe, and setting multiple first guide plates in the dust removal unit, and a dust collection box at the bottom of the first guide plates, allows the air intake airflow to collide with the first guide plates during the air intake process, thereby separating the sand and dust it carries and guiding it into the dust collection box at the bottom of the first guide plates, thus achieving a better dust removal effect and improving the cleanliness of the air intake. Furthermore, the dust collection box is detachably set on the air intake pipe, which facilitates the cleaning of the sand and dust in the dust collection box and effectively prevents the deposited sand and dust from re-entering the air-using components with the air intake airflow, thereby helping to ensure the working performance of the air-using components.

[0014] (2) By setting the second guide plate, it can effectively intercept and filter the sand and dust in the airflow at the top of the air intake pipe, thereby improving the airflow in the air intake pipe and further improving the cleanliness of the air intake. By setting a channel for the airflow to pass through between the first guide plate and the second guide plate, the air intake volume can be guaranteed.

[0015] (3) By tilting the first guide plate and the second guide plate towards the outlet of the intake pipe, the resistance to the intake airflow can be effectively reduced, which can help ensure the intake volume and working performance of the engine.

[0016] (4) By making the projections of the first guide plate and the second guide plate overlap in the direction of the airflow, it is possible to effectively prevent the airflow from carrying sand and dust directly out of the air intake pipe without passing through the filter and interception of the first guide plate or the second guide plate.

[0017] (5) By setting multiple first guide vanes on the first guide plate and multiple second guide vanes on the second guide plate, the airflow bypass effect can capture small particles, which can further improve the dust removal effect of the dust removal unit and improve the air intake cleanliness of the intake system.

[0018] (6) By setting multiple vent holes at the end of the second guide plate away from the first guide plate, some cleaner intake airflow can be allowed to pass directly, which can effectively reduce the overall resistance.

[0019] (7) By setting up an air filter, the sand and dust that have not been intercepted by the first guide plate and the second guide plate can be further filtered out by the air filter to prevent them from entering the air-using components and causing damage to the air-using components.

[0020] (8) By setting an arched part and placing the dust discharge port on the arched part, the top of the arched part can form a conical surface, which can guide the sand and dust, so that the sand and dust can be discharged from the shell through the dust discharge port under the action of gravity.

[0021] In addition, by making the blocking plate include a rod and a plate at the bottom of the rod, the blocking plate can be fixed to the shell by the rod, and a gap for discharging sand and dust can be formed between the plate and the shell.

[0022] (9) By setting the plate body in a conical shape, when sand and dust particles inside the shell are discharged to the blockage plate through the dust discharge port on the arched part, they can flow into the gap under the guidance of the top surface of the blockage plate and then be discharged from the shell through the gap. Setting the dust discharge port in an arc shape along the circumference of the rod body can fully increase the area of ​​each dust discharge port, which is conducive to improving the dust removal effect.

[0023] Another object of this application is to provide a vehicle having an air intake system as described above.

[0024] The vehicle in this embodiment, by setting up the air intake system as described above, helps to ensure the cleanliness of the intake air, thereby effectively preventing sand and dust impurities from entering the engine combustion chamber with the intake air, and thus effectively preventing abnormal wear of internal components of the combustion chamber, which helps to ensure the working performance of the engine.

[0031] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0032] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0033] An embodiment of the first aspect of this application provides an air intake system that can achieve better dust removal effect and improve the cleanliness of the intake air.

[0034] In related technologies, during the operation of internal combustion engines (especially automobile engines), the cleanliness of the intake system directly determines the engine's performance and service life. Currently, this is mainly achieved by relying on the air filter 2 as the core filtration component of the intake system. Air filters 2 generally employ multi-layer fiber filter paper as their core filtration structure. This structure intercepts solid impurities such as sand and dust in the air through the pores between the fibers, preventing these impurities from entering the engine combustion chamber with the intake air and thus preventing abnormal wear on internal combustion chamber components.

[0035] However, in actual use, the connection between the air filter 2 and the intake pipe 1, and the bonding between the filter paper and the filter housing 201, are prone to sealing gaps or aging and damage of the seals under the influence of long-term vibration. Meanwhile, although some air filters 2 are equipped with bypass valves to ensure airflow when the filter paper is clogged, when the seal fails, dust particles in the air can bypass the filter paper and directly invade the intake passage through the sealing gaps or bypass valve, ultimately entering the combustion chamber. This results in poor intake air cleanliness and can easily affect engine performance.

[0036] In addition, in harsh environments with high dust concentrations, the filter paper of air filter 2 will accumulate a large amount of dust in a short period of time, causing the filtration resistance to rise sharply. This will not only lead to a decrease in engine power and an increase in fuel consumption due to insufficient air intake.

[0037] In view of this, in order to overcome the shortcomings of the related technology, the air intake system of this embodiment is suitable for being located at the air intake end of the air-using component, and combined with Figures 1 to 3 As shown, the overall design includes an air intake pipe 1 and a dust removal unit mounted on the air intake pipe 1. The dust removal unit includes multiple first guide plates 3 arranged sequentially along the direction of the airflow, and a dust collection box 4 located at the bottom of each first guide plate 3. Each first guide plate 3 is located inside the air intake pipe 1, and at least a portion of the dust collection box 4 is located outside the air intake pipe 1, and the dust collection box 4 is detachably mounted on the air intake pipe 1.

[0038] Therefore, by setting a dust removal unit on the intake pipe 1, and setting multiple first guide plates 3 in the dust removal unit, as well as a dust collection box 4 at the bottom of the first guide plate 3, the intake airflow can collide with the first guide plate 3 during the intake process, which can change the direction and speed of the intake airflow. This causes the sand and dust it carries to separate due to inertia and fall into the dust collection box 4 at the bottom of the first guide plate 3 under its guidance, thereby achieving a better dust removal effect and improving the cleanliness of the intake air.

[0039] The dust collection box 4 is detachably mounted on the intake pipe 1, which facilitates the cleaning of sand and dust inside the dust collection box 4 and effectively prevents the deposited sand and dust from re-entering the engine with the intake airflow, thereby ensuring the engine's operating performance. At the same time, the cleaned dust collection box 4 can be reinstalled on the intake pipe 1 to prevent sand and dust from re-entering the engine.

[0040] Based on the above overview, generally, to ensure the stability of the intake pipe 1, a bracket can be further installed on the intake pipe 1 to fix it to the vehicle body longitudinal beam or other components. Furthermore, unlike the conventional intake pipe 1 which uses a round pipe, in this embodiment, to facilitate the installation of the first guide plate 3 and the dust collection box 4, the intake pipe 1 includes a rectangular main body and a transition section located at the air outlet end of the main body. The air outlet end of the transition section is circular to facilitate connection with the air filter 2 described below.

[0041] The main body of the intake pipe 1 has four flat side walls, which provide mounting surfaces for the first guide plate 3 and the dust collection box 4, thus facilitating the installation of the first guide plate 3 and the dust collection box 4 on the intake pipe 1. In addition, the main body of the intake pipe 1 is made of a rectangular tube, which also facilitates the installation of the bracket, thereby making it easier to further fix the intake pipe 1 to the vehicle body.

[0042] It is worth noting that, provided the installation requirements are met, it is also feasible to use a round pipe or other shapes for the intake pipe 1.

[0043] In addition, combined Figures 2 to 5 As shown in the diagram, in a specific implementation, the dust collection box 4 is located on the bottom wall of the air intake pipe 1, and the first guide plate 3 is located at the bottom of the dust collection box 4, thus connecting the dust collection box 4 to the lower part of the air intake pipe 1. Under inertia, the dust in the intake airflow tends to move downwards. At this time, the arrangement of the first guide plate 3 can intercept most of the dust in the intake airflow, especially the larger particles, thus effectively improving the cleanliness of the intake air.

[0044] Furthermore, in this embodiment, as Figure 3 As shown, the first deflector 3 and the dust collection box 4 are specifically four spaced apart along the length of the intake pipe 1. This arrangement creates a four-stage interception of the intake airflow, effectively preventing sand and dust from entering the engine. It is understandable that, in addition to setting the first deflector 3 and the dust collection box 4 in four spaced-apart configurations, setting them in three, five, or other quantities is also feasible.

[0045] like Figure 5 As shown, the dust collection box 4 in this embodiment is specifically rectangular, with protruding mounting plates 401 at both ends. The dust collection box 4 is mounted on the air intake pipe 1 by bolts passing through the mounting plates 401. In addition, to facilitate the assembly and disassembly of the dust collection box 4, nuts corresponding to those provided on the mounting plates 401 can be welded inside the air intake pipe 1 in a specific implementation.

[0046] Continue to combine Figures 2 to 4 As shown, in some exemplary embodiments, the dust removal unit includes a plurality of second guide vanes 5 sequentially disposed within the intake pipe 1 along the direction of the intake airflow. Furthermore, in the vertical direction of the vehicle, the second guide vanes 5 are positioned above the first guide vane 3, and a channel is formed between the first guide vane 3 and the second guide vanes 5 for the intake airflow to pass through.

[0047] Since the first deflector 3 mainly intercepts the airflow passing through the lower part of the intake pipe 1, there is still room for improvement if only the first deflector 3 is installed. Therefore, in combination with Figures 2 to 4 As shown, the dust removal unit also includes a plurality of second guide plates 5 arranged sequentially in the intake pipe 1 along the direction of the intake airflow. Furthermore, in the vertical direction of the vehicle, the second guide plates 5 are located above the first guide plate 3, and a channel is formed between the first guide plate 3 and the second guide plates 5 for the intake airflow to pass through.

[0048] Here, the second guide vane 5 effectively intercepts and filters sand and dust in the intake airflow above the intake pipe 1, directing the intercepted sand and dust into the dust collection box 4 at the bottom of the first guide vane 3. This improves the filtration of the intake airflow within the intake pipe 1, further enhancing the cleanliness of the intake air. Furthermore, the passage between the first guide vane 3 and the second guide vane 5 ensures sufficient intake volume to guarantee engine performance.

[0049] In some exemplary embodiments, along the direction of the intake airflow, the first guide vane 3 is inclined from bottom to top toward the outlet end of the intake pipe 1, and the second guide vane 5 is inclined from top to bottom toward the outlet end of the intake pipe 1. Furthermore, the projections of the second guide vane 5 and the first guide vane 3 in the vertical direction of the vehicle at least partially overlap.

[0050] By tilting both the first guide vane 3 and the second guide vane 5 toward the outlet of the intake pipe 1, the air intake airflow can be effectively blocked by sand and dust, and the resistance to the airflow can be effectively reduced. This can effectively prevent the intake volume from being affected by the setting of the first guide vane 3, and help ensure the intake volume and working performance of the engine.

[0051] Simultaneously, the projections of the second guide vane 5 and the first guide vane 3 in the vertical direction of the vehicle at least partially overlap. This arrangement allows the sand and dust filtered by the second guide vane 5 to slide down onto the first guide vane 3 under gravity and eventually enter the dust collection box 4. This effectively prevents the sand and dust intercepted by the second guide vane 5 from scattering at the bottom of the intake pipe 1, which would hinder cleaning, and also prevents it from flowing out of the intake pipe 1 again with the airflow.

[0052] Combination Figures 2 to 4 As shown, in specific implementation, the number of first guide plates 3 should be greater than the number of second guide plates 5, so that the sand and dust intercepted by the second guide plates 5 can be discharged from the air intake pipe 1 through the dust collection box 4 at the bottom of the first guide plates 3. For example, as Figure 3 As shown, the second guide vanes 5 can be configured as three spaced apart, while the first guide vanes 3 can be configured as four spaced apart, with the three second guide vanes 5 respectively positioned above the three first guide vanes 3. It is understood that the second guide vanes 5 can be configured as two or other numbers besides three spaced apart.

[0053] Furthermore, along the direction of the airflow, the upper end of the first guide plate 3 protrudes towards the air outlet of the intake pipe 1 relative to the lower end of the second guide plate 5. That is, the projections of the first guide plate 3 and the second guide plate 5 in the vertical direction of the vehicle overlap. This arrangement effectively ensures that the sand and dust intercepted by the second guide plate 5 slides down from its bottom end onto the first guide plate 3 under the guidance of the second guide plate 5, and then falls into the dust collection box 4 under the guidance of the first guide plate 3.

[0054] It should be noted that, in addition to ensuring that the projections of the first air deflector 3 and the second air deflector 5 overlap in the vertical direction of the vehicle, it is also possible for the projections of the first air deflector 3 and the second air deflector 5 to completely overlap in the vertical direction of the vehicle.

[0055] In addition, in order to balance the effect of intercepting sand and dust and the intake resistance, in some exemplary embodiments, the angle between the first guide plate 3 and the second guide plate 5 and the length direction of the intake pipe 1 can be set to between 30° and 60°.

[0056] In practice, the first guide vane 3 and the second guide vane 5 can be tilted at the same angle, for example... Figure 3 As shown, the angle between the first guide plate 3 and the second guide plate 5 and the length direction of the intake pipe 1 is set to 55°. Of course, it is also feasible to set other values ​​such as 35°, 40°, 60°, etc., between the first guide plate 3 and the second guide plate 5 and the length direction of the intake pipe 1.

[0057] It should be mentioned that, in addition to making the first guide vane 3 and the second guide vane 5 have the same tilt angle, the tilt angles of the first guide vane 3 and the second guide vane 5 can also be different. For example, the angle between the first guide vane 3 and the length direction of the intake pipe 1 can be set to 40°, while the angle between the first and second guide vanes 5 and the length direction of the intake pipe 1 can be set to 50°.

[0058] In some exemplary embodiments, the projection portions of the first guide vane 3 and the second guide vane 5 in the direction of the intake airflow overlap. By making the projection portions of the first guide vane 3 and the second guide vane 5 overlap in the direction of the intake airflow, it is possible to effectively prevent the intake airflow from carrying sand and dust directly out of the intake pipe 1 without passing through the filtration of the first guide vane 3 or the second guide vane 5.

[0059] In specific implementation, such as Figure 3 As shown, the top of the first guide vane 3 is higher than the bottom of the second guide vane 5. This arrangement ensures that the intake airflow must pass through the first guide vane 3 or the second guide vane 5 before flowing out of the intake pipe 1. Simultaneously, this design also alters the direction of the intake airflow, allowing dust to be further expelled due to inertia, thereby further improving the cleanliness of the engine's intake air.

[0060] In some exemplary embodiments, at least one first guide plate 3 is provided with a plurality of first guide vanes 301 spaced apart, each first guide vane 301 extending along the inclined direction of the first guide plate 3. Here, by providing a plurality of first guide vanes 301 on the first guide plate 3, the airflow around the guide plate facilitates the capture of small particles. Simultaneously, at least one first guide plate 3 is provided with a plurality of second guide vanes 501 spaced apart, each second guide vane 501 extending along the inclined direction of the second guide plate 5. This design facilitates the second guide plate 5 in capturing small particles using the airflow around the guide plate.

[0061] In specific implementation, such as Figure 5 As shown, to achieve better dust removal, each first guide plate 3 is provided with a first guide vane 301. The first guide plate 3 can be rectangular, with its length direction forming an angle with the length direction of the air intake pipe 1, thus achieving an inclined arrangement of the first guide plate 3. Simultaneously, multiple first guide vanes 301 are spaced apart along the width direction of the first guide plate 3, and can be evenly or unevenly distributed. Each first guide vane 301 extends along the length direction of the first guide plate 3, from its top end to its bottom end.

[0062] In addition, such as Figure 6 As shown, in order to achieve better dust removal effect, each second guide plate 5 is provided with a second guide vane 501. The second guide plate 5 can be set as a rectangle, and its length direction forms an angle with the length direction of the air intake pipe 1 to achieve the inclined setting of the second guide plate 5. At the same time, multiple second guide vanes 501 are spaced apart along the width direction of the second guide plate 5, and each second guide vane 501 extends along the length direction of the second guide plate 5.

[0063] It should be noted that, in addition to setting the first guide vane 301 on the first guide plate 3 and setting the second guide vane 501 on the second guide plate 5, it is also possible to set the first guide vane 301 only on the first guide plate 3 or set the second guide vane 501 only on the second guide plate 5.

[0064] In this embodiment, in some exemplary implementations, at least one of the second guide plates 5 has multiple vents 502 at the end away from the first guide plate 3, and each vent 502 is used to allow intake airflow to pass through. Because sand and dust tend to sink under gravity, the upper and middle parts of the intake pipe 1 are non-core interception areas. Therefore, by providing multiple vents 502 at the end of the second guide plate 5 away from the first guide plate 3, i.e., at the top of the second guide plate 5, some cleaner intake airflow can be allowed to pass directly, effectively reducing overall resistance.

[0065] In specific implementation, such as Figure 6 As shown, each of the second guide plates 5 is provided with a vent hole 502, and the vent holes 502 can be arranged in multiple rows at intervals, and each row of vent holes 502 can be arranged in multiple intervals. Moreover, the diameter of each vent hole 502 can be set between 3mm and 5mm. In addition, the diameter of each vent hole 502 can be set to the same value or to different values.

[0066] In some exemplary embodiments, the intake system of this embodiment further includes an air filter 2 disposed at the outlet end of the intake pipe 1. The air filter 2 has a dust discharge port 20111 at the bottom of its housing 201, and a blocking plate 202 positioned at the bottom of the dust discharge port 20111. A gap is formed between the blocking plate 202 and the housing 201, allowing communication with the outside. By further configuring the air filter 2, sand and dust not intercepted by the first guide plate 3 and the second guide plate 5 can be further filtered out by the air filter 2, preventing them from entering the engine and causing damage.

[0067] Meanwhile, the air filter 2 has a mature structure, is readily available, and easy to implement. It also possesses good filtration properties, further improving the cleanliness of the engine's intake air. Furthermore, the gap between the plug plate 202 and the housing 201 allows sand and dust filtered by the air filter 2 to be discharged through this gap.

[0068] In specific implementation, combined with Figure 1 , Figures 7 to 9 As shown, the air filter 2 has the same structure as the prior art, with its housing 201 also including an upper housing 201 and a lower housing 201 that are fastened together, and a filter element is provided inside the housing 201. Its specific structure can be referred to the prior art. In this embodiment, the blocking plate 202 is specifically located at the lowest end of the lower housing 201 to facilitate sand and dust to automatically move to the gap under the action of gravity.

[0069] In some exemplary embodiments, the bottom of the housing 201 has an arched portion 2011 that arches into the housing 201, and a protruding ring 2012 surrounding the arched portion 2011, the protruding ring 2012 protruding outward from the housing 201. A dust discharge port 20111 is located on the arched portion 2011, and the blocking plate 202 includes a rod 2021 inserted into the arched portion 2011, and a plate 2022 located at the bottom of the rod 2021, with a gap between the plate 2022 and the protruding ring 2012.

[0070] At this time, an arched portion 2011 that arches into the housing 201 is provided at the bottom of the housing 201, and a dust discharge port 20111 is provided on the arched portion 2011. As a result, the top of the arched portion 2011 forms a conical surface, which can guide the sand and dust, so that the sand and dust can be discharged from the housing 201 through the dust discharge port 20111 under the action of gravity.

[0071] By providing a protruding ring 2012 around the arched portion 2011, the structural strength of this part of the housing 201 is improved, and it is also beneficial to form a gap between the blocking plate 202 and the housing 201, and to ensure the stability of the gap size. In addition, by making the blocking plate 202 include a rod 2021 and a plate 2022 provided at the bottom of the rod 2021, it is easy to fix the blocking plate 202 to the housing 201 through the rod 2021. At the same time, a gap for expelling sand and dust can also be formed between the plate 2022 and the housing 201.

[0072] In this embodiment, during specific implementation, in combination with Figures 9 to 11 As shown, for ease of manufacturing, the lower housing 201 is generally rectangular, with the blocking plate 202 located at one of its pointed corners, while the arched portion 2011 is circular. Additionally, in conjunction with... Figure 10 and Figure 11 As shown, to facilitate manufacturing and improve the stability of the blocking plate 202, the rod 2021 and the plate 2022 are integrally formed in this embodiment. Specifically, the gap is a ring around the circumference of the convex ring 2012, and can be designed to be between 0.5mm and 1.0mm to prevent the gap from being too small, which would prevent deposited sand and dust from escaping and ultimately accumulating at the bottom of the housing 201. Simultaneously, it effectively prevents the negative pressure inside the housing 201 from drawing in unfiltered external air through the gap during engine intake.

[0073] Furthermore, to facilitate the removal of the blocking plate 202 for cleaning sand and dust adhering to it, in one exemplary embodiment, the blocking plate 202 is detachably mounted on the arched portion 2011. Continuing with the combination... Figures 9 to 11As shown, in a specific implementation, a retaining ring 20211 that protrudes radially outward can be provided on the rod 2021, and the end of the retaining ring 20211 away from the plate 2022 is tapered to guide the retaining ring 20211 into the retaining hole.

[0074] Correspondingly, such as Figure 9 As shown, the arched portion 2011 has an insertion hole for the arch rod 2021 and a slot located within the insertion hole. As the rod 2021 is inserted into the insertion hole, it is secured in the slot by a retaining ring 20211. This design allows the blockage plate 202 to be pulled out and cleaned before being reinstalled on the housing 201 when dust accumulates on it after prolonged use.

[0075] In some of the exemplary implementations, combined with Figures 9 to 11 As shown, the plate 2022 is conical. This design allows particles such as sand and dust inside the housing 201 to flow into the gap under the guidance of the top surface of the blockage plate 202 when they are discharged to the blockage plate 202 through the dust outlet 20111 on the arched part 2011. They can then be discharged from the housing 201 through the gap.

[0076] It is understandable that, in addition to setting the plate 2022 into a cone shape and setting the dust outlet 20111 into a flat plate, it is theoretically also feasible.

[0077] In some of the exemplary implementations, such as Figure 8 As shown, the dust discharge port 20111 is an arc shape arranged circumferentially along the rod body 2021. This significantly increases the area of ​​each dust discharge port 20111, thereby improving the dust removal effect. Furthermore, there are multiple dust discharge ports 20111 arranged around the rod body 2021, for example... Figure 8 The four shown are designed to ensure that sand and dust inside the housing 201 are fully discharged onto the blocking plate 202, and then discharged through the blocking plate 202. Furthermore, each dust discharge port 20111 is an arc shape arranged circumferentially along the arched portion 2011. It should be noted that, besides setting the dust exhaust port 20111 to an arc shape, it can also be set to a circle or other irregular shape. Furthermore, the number of dust exhaust ports 20111 is not limited. Figure 8 As shown, it can be adjusted accordingly based on design requirements. Furthermore, it should be mentioned that during implementation, it can be combined with... Figures 8 to 11 As shown, the plate 2022 is set in a conical shape, and the dust discharge port 20111 is an arc shape set along the circumference of the rod 2021, so as to have a better dust removal effect.

[0078] It is worth noting that, regarding the intake system of this embodiment, based on the above exemplary embodiments, in specific implementation, as a preferred embodiment, it is still composed of... Figures 1 to 11 As shown, it may include, for example, an air inlet pipe 1 equipped with a dust removal unit and an air filter 2.

[0079] The dust removal unit includes four first guide plates 3 and three second guide plates 5 arranged sequentially along the direction of the airflow, and a dust collection box 4 located at the bottom of each first guide plate 3. The dust collection box 4 is located outside the air intake pipe 1 and is detachably mounted on the air intake pipe 1.

[0080] Along the direction of the intake airflow, the first guide plate 3 is inclined from bottom to top toward the outlet end of the intake pipe 1, and the second guide plate 5 is inclined from top to bottom toward the outlet end of the intake pipe 1. The projection of the second guide plate 5 and the first guide plate 3 in the vertical direction of the vehicle overlaps.

[0081] The bottom of the housing 201 is provided with an arched portion 2011 that arches into the housing 201, and a protruding ring 2012 surrounding the arched portion 2011. The protruding ring 2012 protrudes outward from the housing 201. The dust discharge port 20111 is provided on the arched portion 2011. The blocking plate 202 includes a rod 2021 inserted into the arched portion 2011 and a conical plate 2022 provided at the bottom of the rod 2021. The gap is located between the plate 2022 and the protruding ring 2012.

[0082] In the preferred embodiment of the above air intake system, the specific configuration and arrangement of the air intake pipe 1, the dust removal unit and the air filter 2, etc., can still be referred to the descriptions in the above exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the air intake pipe 1, the dust removal unit and the air filter 2, etc., can also be referred to the descriptions in the above exemplary embodiments.

[0083] The air intake system of this embodiment adopts the above design, so that the airflow collides with the first guide plate 3 and the second guide plate 5 during the intake process, causing the sand and dust it carries to be separated and fall into the dust collection box 4 at the bottom of the first guide plate 3 under its guidance. At the same time, the airflow flowing out of the air intake pipe 1 can be further filtered again by the air filter 2, thereby achieving a better dust removal effect and improving the cleanliness of the intake air.

[0084] An embodiment of the second aspect of this application provides a vehicle having the above-described air intake system.

[0085] The vehicle in this embodiment, by setting up the above-mentioned air intake system, helps to ensure the cleanliness of the intake air, thereby effectively preventing sand and dust impurities from entering the engine combustion chamber with the intake air, thus preventing abnormal wear of internal components of the combustion chamber and helping to ensure the working performance of the engine.

[0086] The above are merely some embodiments of this application and are not intended to limit this application. The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this application should be included within the protection scope of the claims of this application.
