Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

Referring to fig. 1-4, a durable air filter for a vehicle comprises a protective cylinder 1, wherein two opposite side walls of the protective cylinder 1 are respectively provided with an air inlet 2 and an air outlet 5, a partition plate 3 is hermetically and rotatably connected in the protective cylinder 1, and the rotation axis of the partition plate 3 is a horizontal axis of the protective cylinder 1 in the state of fig. 1.

Baffle 3 separates into two C chambeies and the D chamber that do not communicate with each other with a protection section of thick bamboo 1, and the C chamber all inlays with the D intracavity and is equipped with hollow filter core 4, D intracavity bottom fixedly connected with connecting rod 41, and the quarter butt 411 of fixedly connected with magnetostrictive material on connecting rod 41's the lateral wall, the lateral wall fixedly connected with permanent magnet 6 of filter core 4.

It should be noted that the connecting rod 41 is located on the vertical axis of the filter element 4, the length of the short rod 411 is slightly smaller than the hollow aperture inside the filter element 4, and in addition, the two side edges of the partition board 3 are both provided with through slots 31 (as shown in fig. 2). Thus, after the partition board 3 is rotated, the connecting rod 41 and the short rod 411 are always positioned in the hollow part of the filter element 4, and the rotation of the partition board 3 is not influenced.

The lateral wall of a protection section of thick bamboo 1 is seted up rather than communicating spout 7 in inside, install control baffle 3 pivoted controlling means in the spout 7, baffle 3 is 45 degrees with permanent magnet 6's contained angle, and permanent magnet 6 distributes on the vertical axis of a protection section of thick bamboo 1 (can specifically refer to and make shown in figure 2), so can guarantee that filter core 4 in the C intracavity is blockked up the back, can make baffle 3 rotate under the action of gravity, dust outlet 10 has been seted up to the interior bottom of a protection section of thick bamboo 1, and install the valve in the dust outlet 10.

The control device comprises a sliding block 8 which is connected in the sliding groove 7 in a sealing and sliding mode, the sliding block 8 is made of magnetic materials, the sliding block 8 is opposite to the adjacent permanent magnet 6 in a heteropolar mode, and the sliding block 8 is elastically connected to the inner wall of the sliding groove 7 through a spring 9.

In the initial state, the natural length of the spring 9 is long, and the slider 8 can be pushed to a position far from the permanent magnet 6. When the device is used, the air outlet 5 is connected with the air inlet end of an engine, and air entering the engine enters the protective cylinder 1 along the air inlet 2, is filtered by the filter element 4 in the cavity C and then enters the engine from the air outlet 5. And the filter element 4 in the cavity D does not filter air, so that the air is clean and clean.

The engine is pulsed both intake and exhaust due to the operating characteristics of the engine. When air flows in the cavity C, the air flow rate and the pressure intensity in the cavity C are high, the air flow rate in the chute 7 communicated with the protective cylinder 1 is low, and the pressure intensity is high, so that a pressure intensity difference can be generated between the chute 7 and the cavity C, the slider 8 can be pushed to a position close to the permanent magnet 6 by the atmospheric pressure (as shown in figure 1), the air in the chute 7 is extruded into the cavity C (the air flow direction is shown in the arrow direction of figure 3), and the permanent magnet 6 in the cavity C is attracted to be attached to the slider 8, so that the position of the filter element 4 is kept stable.

During the interval of engine air intake, the air in the cavity C does not flow any more, the pressure difference between the chute 7 and the cavity C disappears, and the spring 9 pushes the slide block 8 away from the permanent magnet 6. The air inlet interval of the engine is very short, when the spring 9 does not push the sliding block 8 far, air inlet is started again, at the moment, pressure difference is generated between the sliding groove 7 and the cavity C, the sliding block 8 is enabled to be close to the permanent magnet 6 again, and therefore the sliding block 8 can move back and forth near the permanent magnet 6 in the pulse air inlet process of the engine.

When the filter element 4 in the cavity C is gradually blocked, the air flow rate passing through the filter element 4 is gradually reduced, the flow speed difference between the cavity C and the chute 7 is also gradually reduced, the pressure difference between the cavity C and the chute 7 is also gradually reduced, and the slide block 8 moves back and forth at a position far away from the permanent magnet 6 under the elastic force action of the spring 9 (as shown in fig. 4). Meanwhile, after a large amount of dust and sand are adhered to the filter element 4 in the cavity C, the total mass of the filter element is increased, the slide block 8 is far away from the permanent magnet 6 in the cavity C, the magnetic force between the slide block and the permanent magnet 6 is small and can be ignored, the partition plate 3 rotates along the rotating axis of the partition plate under the action of gravity, the clean filter element 4 in the cavity D is rotated into the cavity C for use, and the blocked filter element 4 in the cavity C is rotated into the cavity D.

After the clean filter element 4 enters the cavity C, the air flow rate in the cavity C is increased again, and the sliding block 8 moves back and forth near the permanent magnet 6 in the cavity C again, so that the position of the filter element 4 in the cavity C is kept stable.

Meanwhile, in the process that the magnetic slide block 8 moves back and forth near the permanent magnet 6 in the cavity C, the magnetic field intensity generated by the two permanent magnets 6 can be changed continuously, the short rod 411 made of magnetostrictive materials can stretch out and draw back continuously under the alternating magnetic field, and the pulse period of air inlet of the engine is extremely short, and the frequency of the back and forth movement of the slide block 8 is extremely high, so that the alternating frequency of the magnetic field intensity and the frequency of the stretching of the short rod 11 are also extremely high, the high-frequency shaking of the filter element 4 in the cavity D can be caused, dust and sand adhered to the filter element 4 can be shaken off, the blocked filter element 4 has good permeability and filtering effect again, and after the filter element 4 in the cavity C is blocked, the control device drives the partition plate 3 to rotate, and the permeable filter element 4 in the cavity D is switched into. So can make this device have very long life, very durable, prolong the change cycle of the inside filter core of air cleaner greatly, reduce the maintenance cost of car, only need regularly open out dirt mouth 10, the clearance D intracavity is shaken off the dust and sand can.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
