Abstract
The utility model relates to an air filter, belonging to the field of automotive parts. The air filter comprises an inner layer of cylindrical wire mesh, an outer layer of cylindrical wire mesh, a filter paper which is clamped between the inner layer of cylindrical wire mesh and the outer layer of cylindrical wire mesh, an upper end cover and a lower end cover. The utility model is characterized in that the upper end cover is a polyurethane end cover which is added with a polyurethane sealing ring. As the adopted polyurethane end cover can be bonded with the wire mesh and the filter paper firmly, when in manufacturing, the utility model can be molded into one body by a casting mode, has simple installation and firm sealing, leads the air filter to be jointed with an air inlet of an engine tightly bacause of the added sealing ring, thus having good air tightness; and simultaneously, due to the characteristics of the polyurethane, the air filter can be recycled and pollution and waste are reduced.
Description
Technical field
The utility model belongs to the auto parts machinery field, specifically is a kind of air-strainer that is used for engine intake.
Background technique
The engine intake of automobile generally need be installed air-strainer, is used for filtered air, in order to avoid airborne impurity enters motor, causes motor to damage.Generally by clamping filter paper in the middle of the inside and outside two-layer thin wire gauze, two ends seal by crown cap existing air-strainer then.But the sealing cover at two ends adopts metallic material up and down, installation process more complicated, and poor air-tightness in actual use.Simultaneously, be inconvenient to recycle.
The model utility content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of air-strainer simple, that tightness is good of installing is provided.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of air-strainer, comprise inside and outside two-layer cylindrical shape chain link fence and be clipped in filter paper and upper end cap and lower end cap between the inside and outside two-layer chain link fence, it is characterized in that upper end cap is the polyurethane end cap, is added with the polyurethane seal ring on the polyurethane end cap.
Upper end cap is provided with seal ring simultaneously owing to adopt polyurethane material to fit tightly with engine intake, has increased sealing effect.
The beneficial effect that the utility model air-strainer is had is: the polyurethane end cap can with chain link fence and filter paper good bond, can be shaped to one by pouring type during making, install simple, secure seal, add seal ring, make to fit tightly that tightness is good with engine intake.Because the characteristic of polyurethane can be recycled, reduced and polluted and waste simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein: 1, seal ring 2, upper end cap 3, filter paper 4, chain link fence 5, lower end cap 6, fixed hole
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, air-strainer comprises that folding filter paper 3 is clipped within the inside and outside two-layer cylindrical shape chain link fence 4, the lower end is provided with end cover, lower end cap 5 can be metallic material or other material that is fit to, the upper end is provided with upper end cap 2, and correspondence is provided with seal ring 1 with car engine air admittance mouth link position on the upper end cap 2.Upper end cap 2 and sealed loop-pad 1 adopts polyurethane material, and can make it bonding with chain link fence 4, filter paper 3 upper ends by pouring type, disposal molding.
On the upper end cap 2 breach or lines can also be set.
The structure of the filter paper 3 of air-strainer, inside and outside chain link fence 4 and lower end cap 5 and combination are common prior art.The utility model does not change the mounting type of air-strainer.
Claims (2)
1, a kind of air-strainer, comprise inside and outside two-layer cylindrical shape chain link fence (4) and be clipped in filter paper (3) and upper end cap (2) and lower end cap (5) between the inside and outside two-layer chain link fence, it is characterized in that upper end cap (2) is the polyurethane end cap, is added with polyurethane seal ring (1) on the polyurethane end cap.
2, air-strainer according to claim 1 is characterized in that the upper end of described polyurethane end cap and inside and outside two-layer cylindrical shape chain link fence (4) and filter paper (3) is cast for one.
