Abstract
The invention relates to an air filter of vehicle, which comprises: main body, lower cover, filter element, and rubber end cover, wherein it is characterized in that: two ends of filter element are arranged with rubber end covers; the part of main body that mounted with filter element has one annular ring; therefore, the invention has additional radial sealing type, with general axial sealing type, to realize double sealing.
Description
Technical field
The present invention relates to a kind of filter cleaner, definite a kind of air filter for automobile of saying so.
Background technique
Empty filter is one of indispensable component of motor car engine, the general mode of structure of present empty filter is at filter core end cap sticking rubber seal ring, filter core is pressed near on the enclosure interior plane of steam outlet pipe position with thread mechanism or with lower cover by trying to stop people from fighting each other in the middle of the filter cleaner, plays the effect of sealing.The empty filter of this structure because the plane of housing seal filter core is because punching press or welding cause air spots easily, thereby causes sealing effect bad, causes grey phenomenon; Renew cartridge more just after adding upper filter and need maintaining 4-5 time, be bonded at rubber pad time of filter core end cap long can flexibility decrease, decrement reduces, and causes grey phenomenon.
Summary of the invention
Purpose of the present invention is the saturating grey problem that solves empty filter, realizes double-sealing.
For reaching above purpose, air filter for automobile, mainly form, it is characterized in that, be provided with end cover rubber between the two ends of described filter core, loam cake and the lower cover by the filter core that communicates with steam outlet pipe that is provided with in the horizontally disposed suction tude in steam outlet pipe, lower end that is arranged on the housing upper end, the housing; On the inwall of loam cake, be provided with annular ring with end cover rubber hole wall connecting part.Described end cover rubber is made by the PU rubber material.Described end cover rubber hole wall is stuck on the annular ring external diameter, and end cover rubber upper lobes structure is pressed on the loam cake inner plane.
By above setting, the present invention has reached double-sealing, promptly except the axial seal mode that common empty filter adopted, increase the radial seal mode, and the radial seal mode loses efficacy never.
Description of drawings
Now the invention will be further described in conjunction with the accompanying drawings.
Fig. 1 is the whole sectional view of the present invention
Fig. 2 is an I part enlarged view of the present invention
Among the figure 1, steam outlet pipe 2, annular ring 3, end cover rubber 4, filter core 5, blade ring 6, suction tude 7, lower cover 8, loam cake 9, housing A, radial seal place B, end face seal place
Embodiment
As shown in Figure 1, air filter for automobile, mainly form, be provided with end cover rubber 3 between the two ends of described filter core 4, loam cake 8 and the lower cover 7 by the filter core 4 that communicates with steam outlet pipe 1 that is provided with in the horizontally disposed suction tude 6 in the steam outlet pipe 1, the lower end that are arranged on housing 9 upper ends, the housing 9; On the inwall of loam cake 8, be provided with annular ring 2 with end cover rubber 3 hole wall connecting parts.
Described end cover rubber 3 is made by the PU rubber material, and this elastic properties of materials is good, and is anti-aging.
Described end cover rubber 3 hole walls are stuck on annular ring 2 external diameters, play the effect (seeing the A place among Fig. 2) of radial seal; End cover rubber 3 upper lobes structures are pressed on loam cake 8 inner planes, play the effect (seeing the B place among Fig. 2) of axial seal.
