Abstract

The utility model relates to a filter core of an air filter of a motor vehicle, which is easy to be recycled and belongs to the technological field of the engine. The filter core solves the problem of recycling the filter core. In the technical proposal, the filter core consists of an internal screen cylinder, an external screen cylinder, folded and rolled cylindrical filter paper arranged between two screen cylinders, and two end covers that are respectively at the two ends of the screen cylinder; the internal screen cylinder and the external screen cylinder have the same shaft and the same length; after being improved, elastic sealing gaskets are respectively arranged between the two end faces of the cylindrical paper and the end covers; and the elastic sealing gaskets are bonded with the cylindrical paper. The filter core can be conveniently disassembled and assembled; the metal components can be repeatedly used; the filter paper can be easily recycled; and the filter core greatly reduces the use costs of the air filter, and reduces the environmental pollution.

Description

A kind of motor vehicle air filter filter core that is easy to reclaim

Technical field

The utility model relates to a kind of internal-combustion engine paper air cleaner filter core, belongs to technical field of engines.

Background technique

Traditional air cleaner cartridge generally by coaxial isometric inside and outside two screen drums, be added in the folding tubular filter paper that rolls between two screen drums and the end cap that is arranged at the screen drum two ends is respectively formed, inside and outside two screen drums are generally made by chain link fence or stephanoporate steel plate, the end cap at two ends is made by steel plate, the end cap at inside and outside two screen drums and two ends welds together, filter paper is then bonding by glue and two end caps, to reach sealing effect.The shortcoming of this structure is after the filter core use is scrapped, because it constitutes an integral body with screen drum, decomposes the recovery difficulty.Like this, after filter core uses a period of time to scrap, completely thrown away, both wasted material, polluted environment again together with screen drum.And the filter core of traditional filter cleaner also is not easy to judge the quality of filter paper all in the inside.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, the motor vehicle air filter filter core that does not produce discarded steel, is easy to reclaim after a kind of the use is provided.

Problem described in the utility model realizes with following technical proposals:

A kind of motor vehicle air filter filter core that is easy to reclaim, by coaxial isometric inside and outside two screen drums, be added in the folding tubular filter paper 4 that rolls between two screen drums and the end cap that is arranged at the screen drum two ends is respectively formed, after the improvement, between the both ends of the surface of described tubular filter paper and end cap, respectively set up an elastic sealing gasket 3, described elastic sealing gasket 3 and tubular filter paper 4 bondings.

The above-mentioned motor vehicle air filter filter core that is easy to reclaim has the welding of an end and one of them end cap in the described screen drum, the other end does not weld.

The above-mentioned motor vehicle air filter filter core that is easy to reclaim, between the wrinkle of described tubular filter paper 4, be provided with 3～4 with tubular filter paper 4 isometric and with the stay 14 of tubular filter paper parallel axes, described stay 14 is uniform on tubular filter paper 4.

The above-mentioned motor vehicle air filter filter core that is easy to reclaim, described elastic sealing gasket 3 is the PU rubber cushion.

The PU rubber cushion that the utility model adopts and tubular filter paper bonds together had both guaranteed sealing effect as the sealing material between tubular filter paper and the end cap, and tubular filter paper can be separated with two end caps easily; Every layer of screen drum only with the end cap welding of one end, can under the situation of not destroying screen drum and end cap, will scrap filter paper and between screen drum and end cap, take out, or the filter paper of cleaning will be put into, thereby screen drum and end cap can be reused, and filter paper also can reclaim easily.Among the wrinkle of tubular filter paper, arrange stay, can increase the compressive strength of filter paper, guarantee the sealing effect between tubular filter paper and the end cap.The utility model can decompose and assemble easily, and metalwork can be reused, and filter paper also can reclaim easily, greatly reduces the manufacture cost of air-strainer, and each can save about 15 yuan of costs, has also reduced environmental pollution.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 1 is a kind of mounting type schematic representation of the present utility model;

Fig. 2 is a structure sectional view of the present utility model;

Fig. 3 is the sectional view after outer screen drum and the upper end cap welding;

Fig. 4 is the sectional view after internal layer screen drum and the lower end cap welding;

Fig. 5 is the schematic appearance of the tubular filter paper of band elastic sealing gasket;

Fig. 6 is the A-A sectional view of Fig. 5;

Fig. 7 is the shaft side figure of tubular filter paper.

Each label is among the figure: 1, upper end cap, 2, the internal layer screen drum, 3, elastic sealing gasket, 4, tubular filter paper, 5, outer screen drum, 6, lower end cap, 7, suction port, 8, seal ring, 9, strainer cover, 10, go up sealing, 11, filter housing, 12, lower seal, 13, the air outlet, 14, stay.

Embodiment

Referring to Fig. 1 (a kind of mounting structural mode wherein of having drawn), the utility model is installed on air-strainer inside, be fixed by strainer cover 9, because the acting in conjunction of last sealing 10, lower seal 12 and elastic sealing gasket 3, after making that outside air enters filter cleaner from suction port 7, could be after can only filtering by tubular filter paper 4 13 enter engine cylinder through the air outlet.

Referring to Fig. 2, leave fixed bolt hole in the middle of the upper end cap 1, in the middle of the lower end cap 6 air port is arranged, the air after the filtration enters engine cylinder through this air port.

Referring to Fig. 3, Fig. 4, the internal and external layer screen drum is made by stephanoporate steel plate, and upper end cap 1 is welded as a whole with outer screen drum 5, and lower end cap 6 is welded as a whole with internal layer screen drum 2, also can adopt other assembly welding mode when specifically implementing.

Referring to Fig. 5, Fig. 6, Fig. 7, the parallel axes of filter paper broken line and tubular filter paper has equally distributed three stays 14 among the figure, and elastic sealing gasket 3 is positioned on the both ends of the surface of tubular filter paper.

When changing filter paper, upper end cap 1 and outer screen drum 5 and the assembly welding that earlier with assembly welding is one is that the lower end cap 6 of one separates with internal layer screen drum 2, after will changing with the tubular filter paper of the band elastic sealing gasket of crossing then, be the upper end cap 1 of one and outer screen drum 5 again with assembly welding and assembly welding is that the lower end cap 6 and the internal layer screen drum 2 of one combined and can be reused.
