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.

The first embodiment is as follows:

referring to fig. 1-2, a low-consumption air filter for a vehicle includes a housing 1, an air inlet pipe 2 connected to the inside of the housing 1 is installed on a side wall of the housing 1, an air outlet pipe 7 is also installed on the inner bottom of the housing 1, and a partition plate 3 is rotatably connected to the inner wall of the housing 1, wherein the side wall of the partition plate 3 abuts against the inner wall of the housing 1, and the housing 1 is divided into two chambers which are not communicated with each other.

Filter elements 4 are installed at the upper end and the lower end of the partition plate 3, and the installation mode of the filter elements 4 is the existing mature technical means, which is not described in detail herein. And filter core 4 embeds and is equipped with a plurality of elastic rubber tube 5, it should be explained that the outer wall of rubber tube 5 links to each other with filter core 4 is fixed. And the rubber pipes 5 below the partition board 3 are communicated with the air outlet pipe 7 (referring to fig. 2 specifically, the air outlet end of the rubber pipe 5 is in close contact with the inner wall of the casing 1, the air inlet end of the air outlet pipe 7 is arranged at the inner bottom of the casing 1, and when the partition board 3 rotates 180 degrees, the air outlet end of each rubber pipe 5 is just opposite to each air inlet end of the air outlet pipe 7 and is tightly attached together). The side wall of the shell 1 is provided with a detachable sealing plate with good air tightness so as to conveniently replace the filter element 4 in the shell 1.

Further, the side wall of the shell 1 is rotatably connected with a hand wheel 8 which is coaxial with the partition plate 3 and used for adjusting the angle of the partition plate 3. And the hand wheel 8 is provided with a bolt, a pin hole or other locking parts (the locking parts are common angle fixing parts in the prior art, the installation mode and the connection mode with the hand wheel 8 are the existing mature technologies, and the details are not explained) for fixing the angle of the partition plate 3. In addition, the angle that the baffle 3 was adjusted to hand wheel 8 is 180 degrees all the time, and baffle 3 is in horizontal position all the time promptly, can guarantee that rubber tube 5 of baffle 3 below can be with the inlet end zonulae occludens of outlet duct 7, prevents the condition of gas leakage.

Two air guide grooves 31 are formed in the side wall of the partition plate 3, a U-shaped pipe 6 is embedded in the shell 1, one end of the U-shaped pipe 6 is communicated with the inside of the shell 1, and the other end of the U-shaped pipe 6 is communicated with one air guide groove 31. The U-shaped pipe 6 is always in communication with only the air guide groove 31 on the lower side.

When the device is used, the air outlet pipe 7 is connected with the air inlet end of the cylinder of the automobile engine. When the engine admits air, outside air is pumped into the shell 1 along the air inlet pipe 2, filtered by the filter element 4 above the partition plate 3, then pumped into the engine cylinder through the U-shaped pipe 6, the air guide groove 31 and the rubber pipeline 5 below the partition plate 3, and finally pumped into the engine cylinder through the air outlet pipe 7. Therefore, after the filter element is used for a period of time, a large amount of dust and other particulate matters are adsorbed on the filter element 4 above the partition plate 3, the filter element 4 below the partition plate 3 is still brand-new, the hand wheel 8 is rotated to rotate the filter element 4 below the partition plate 3 to the upper side, the filter element above the partition plate 3 is rotated to the lower side to be cleaned, and after the rotation is completed, the locking part is operated to lock the position of the partition plate 3.

The operating characteristics of an automobile engine determine the way in which gases are drawn and expelled in pulses during intake and exhaust of the automobile engine.

Because the air extraction speed is very fast when the engine is air-intake, when air is extracted from the rubber pipeline 5 below the clapboard 3 and outside air is not in time to be supplemented, the air pressure in the rubber pipeline 5 is instantly reduced to force the rubber pipeline 5 to instantly contract and drive the filter element 4 connected with the rubber pipeline 5 to contract together, after outside air flows in and is supplemented, the elastic rubber pipeline 5 is immediately recovered, and because the pulse interval of the air-intake of the engine is very short, the air extraction frequency is very high, the contraction and recovery frequency of the rubber pipeline 5 is also very high. In the high-frequency shrinkage and recovery process of the rubber pipeline 5, other particles such as dust adsorbed on the filter element 4 below the partition plate 3 can be shaken off, so that the filtering performance of the filter element 4 after use is improved. After using for a period of time, rotate hand wheel 8 once more, change over into the filter core 4 of baffle 3 top and clear up baffle 3 below, the filter core 4 of baffle 3 below changes over into the baffle 3 top and uses, guarantees that filter core 4 can repetitious usage.

Example two:

referring to fig. 3-4, the difference from the first embodiment is that a plurality of glass sleeves 9 communicated with the air outlet pipe 7 are embedded in the inner bottom of the shell 1, every two adjacent glass sleeves are symmetrically arranged on two sides of the filter element 4, a sliding block 10 is slidably connected in the glass sleeves 9, and silk 101 is fixedly connected on the side wall of the sliding block 10.

And it should be noted that the side wall of the slider 10 is in close contact with the inner wall of the glass sleeve 9. (particularly, in the manufacturing process, the silk 101 is fixedly arranged on one part of the lower side of the sliding block 10, so that the silk 101 can be rubbed with the glass sleeve 9 when the sliding block 10 moves up and down, and meanwhile, the sliding block 10 and the glass sleeve 9 have good air tightness).

The upper end of the sliding block (10) is elastically connected with the inner top of the glass sleeve (9) through a spring (11). It should be noted that the upper end of the glass sleeve 9 is provided with an air hole 91 to facilitate the up-and-down movement of the slider 10 without being hindered.

In this embodiment, during the air extraction process of the engine, a part of air below the inside of the sliding block 10 in the glass sleeve 9 is also extracted, at this time, the air pressure in the glass sleeve 9 is reduced, the sliding block 10 moves downwards for a certain distance, and after the external air flows in and is supplemented, the spring also pulls the sliding block 10 to move upwards for resetting. So can be at the engine in-process of bleeding, slider 10 constantly reciprocates in glass sleeve 9, silk 101 on the slider 10 lateral wall also with the continuous friction of glass sleeve 9's inner wall and produce static, can adsorb tiny particulate matter on filter core 4 on glass sleeve 9's the surface, promoted filter core 4's cleaning efficiency, also clean more thorough to filter core 4 simultaneously to filtering quality when promoting filter core 4 secondary use.

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.
