All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an air filtering intake system according to an embodiment of the present invention. As shown in fig. 1, the air filter intake system 100 includes:
a first filter 110, an air inlet 111 of the first filter 110 facing upward, so that air enters the first filter 110 in a direction perpendicular to the ground;
and a second filter 120, wherein an air inlet pipe of the second filter 120 is communicated with an air outlet pipe of the first filter 110, and an air inlet tail pipe 122 is connected to the air outlet pipe of the second filter 120.
In the present embodiment, the air intake system 100 includes a first filter 110 and a second filter 120. The filter means a filter that filters foreign substances or gas through filter paper, and the first filter 110 and the second filter 120 in this embodiment are air filter devices. The air inlet 111 of the first filter 110 is communicated with the environment where the vehicle is located, the exhaust pipe of the first filter 110 is communicated with the air inlet pipe of the second filter 120, and the exhaust pipe of the second filter 120 is communicated with the air inlet manifold of the vehicle engine or the air inlet pipe of the turbocharger through an air inlet tail pipe 122.
During the use of the vehicle, the air in the environment firstly enters the first filter 110, is discharged into the second filter 120 after being filtered by the first filter 110, and is discharged into the engine or the turbocharger of the vehicle after being filtered by the second filter 120, so that the fresh air is continuously and efficiently provided for the engine. The exhaust pipe of the second filter 120 is communicated with an intake tail pipe 122 of the engine or the turbocharger, the first filter 110 and the second filter 120 are normally in a negative pressure state, and the air in the environment is influenced by the external atmospheric pressure and enters the first filter 110 in the negative pressure state. Of course, a suction pump may be provided in the first filter 110 and/or the second filter 120 to actively draw ambient air into the first filter 110. Alternatively, the communication portion between the discharge pipe of the first filter 110 and the intake pipe of the second filter 120 may be fixed by a clamp 130 to facilitate mounting and dismounting.
The air filter intake system 100 is generally installed in the head of a vehicle, and defines the traveling direction of the vehicle as the front, the direction opposite to the traveling direction of the vehicle as the rear, and the roof of the vehicle as the upward direction. The air inlet 111 of the first filter 110 is arranged upwards, and the air inlet direction of the first filter 110 is vertical downwards, which is different from the horizontal and transverse air inlet scheme of the traditional filter. Therefore, particles such as gravels in front of the vehicle can be effectively prevented from entering the first filter 110 in the process of driving quickly, and bullets can be prevented from damaging the air inlet 111 of the first filter 110 to a certain extent.
Optionally, the first filter 110 includes: a first housing 112 and a first filter element disposed within the first housing 112;
the first casing 112 includes an upper cover plate, and a first side plate and a second side plate which are arranged oppositely, and both the first side plate and the second side plate are perpendicular to the upper cover plate;
the first side plate faces the forward direction of the vehicle, the second filter 120 is disposed on one side of the second side plate away from the first side plate, and the upper cover plate is provided with the air inlet 111.
The first side plate of the first filter 110 is oriented in the forward direction of the vehicle, and the second filter 120 is disposed on the side of the second side plate away from the first side plate, so that the first filter 110 and the second filter 120 are sequentially disposed in the forward and backward direction in the vehicle traveling direction. In the process of vehicle traveling, if encountering severe environments such as wind, sand, bullet attacks, the first filter 110 is a main attacked object, and the first filter 110 can shield the second filter 120 to a certain extent, so as to protect the second filter 120 from being easily damaged. If the first filter 110 fails and is damaged, the second filter 120 protected by the shielding can still perform air filtering, so as to ensure the normal filtering function of the air filtering and intake system 100.
Optionally, the first side plate is a bulletproof steel plate.
The first side plate is preferably made of a bulletproof steel plate with high strength, and is used for resisting attack of broken stones, bullets and the like, so that the air filtering and air inlet system 100 is prevented from being damaged, and the service life is prolonged. Specifically, the first side plate may be made of a material including, but not limited to, low-alloy ultra-high strength steel plate millux500, ramor450/500, and the like. During specific assembly, the size of the first side plate can be set according to the sizes of the first filter 110 and the second filter 120, so that the first side plate can completely shield the first filter 110 and the second filter 120, and meanwhile, the redundant bulletproof material is prevented from increasing the manufacturing cost.
Optionally, as shown in fig. 1, the upper cover plate is a mesh grid 114.
The upper cover plate of the first filter 110 is set as the mesh grille 114, which can be used as a cover plate to be arranged on the first casing 112 to protect the filter element and other structures inside the first casing 112 from being damaged, and can also prevent large particles such as broken stone from entering under the condition of ensuring air to enter and exit. The mesh grid 114 may be made of metal or other high-strength composite material to improve its strength. The periphery of the mesh grid 114 can be formed by injection molding of a plastic frame, and the mesh grid is fixedly installed at the air inlet 111 of the first filter 110 through screws, so that the filter element can be conveniently detached and replaced. Of course, the mesh layout of the mesh grid 114 is not necessarily a mesh, and other structures such as round hole shape and square hole shape can be applied to the present embodiment, without limitation.
In the air filtering and air intake system provided by the embodiment of the invention, the air filtering and air intake system of the vehicle comprises the first filter and the second filter, and the exhaust pipe of the first filter is communicated with the air inlet pipe of the second filter. Therefore, in the using process, even if one filter fails, the normal air filtering and air intake requirements of the vehicle can be guaranteed. In addition, with the arrangement form that first filter adopted perpendicular air admission, have the secret nature, more impurity particle that appear in avoiding the horizontal air admission scheme gets into the filter to and receive the place ahead bullet to attack and lead to the paralysed technical problem of engine air intake system, reduced the filter core and changed the frequency, improved the air filtration quality of air filter air intake system.
In one embodiment, the first housing 112 has a drainage hole 113; the air filter intake system 100 may further include:

and when the humidity data acquired by the humidity sensor is monitored to be greater than a preset value, controlling the drain hole 113 of the first shell 112 to open for draining water.
In this embodiment, a humidity sensor and an air outlet are additionally provided in the air filter intake system 100 to solve the problem of water inflow that may be caused by the vertical air intake scheme. Specifically, a humidity sensor is provided in the first housing 112 for detecting humidity in the first housing 112.

When the air filtering intake system 100 is applied to vehicles, particularly special combat vehicles, the air filtering intake system has the functions of bulletproof and rainproof, and has extremely high engineering application value.
The controller may be pre-configured to monitor a predetermined value of humidity within the first housing 112, which may be a value of humidity of air that the first filter 110 is capable of normally filtering and using with the engine. If the controller monitors that the actual humidity in the first housing 112 is less than or equal to the preset value, the air humidity does not affect normal filtering and use, and at this time, the controller may control the drain hole 113 of the first housing 112 to close, so as to prevent air from entering the first housing 112 through the drain hole 113. Accordingly, if the controller detects that the actual humidity in the first housing 112 is greater than the preset value and the air humidity has affected normal filtering and use, the controller may control the drain hole 113 of the first housing 112 to open, so as to drain the water in the first housing 112 and reduce the humidity in the first housing 112.
Optionally, the movable assembly may include a piston and a driving member, a driving shaft of the driving member is connected to the piston, and a control end of the driving member is electrically connected to the controller.

Therefore, liquid such as rainwater entering the first shell 112 along the vertical direction can be collected into the bottom sharp corner of the wedge-shaped shell under the action of gravity and is discharged through the water discharge hole 113 formed in the bottom sharp corner, and the water discharge efficiency is high. In addition, the wedge-shaped shell reduces the overall surface area relative to the square shell, saves ballistic material for preparing first shell 112, and reduces processing costs.
In another embodiment, the second filter 120 includes a second cylindrical housing 121 and a second filter element, which is disposed in the housing;
