Abstract
The utility model relates to an air filter, which comprises a shell containing a cylindrical inner cavity and a hollow cylindrical filter cartridge arranged in the inner cavity of the shell, wherein an air inlet is formed on the lateral surface of the shell; an air outlet is formed on the end face of one end of the shell; an axis of the filter cartridge is parallel to that of the inner cavity of the shell; the axis of the filter cartridge has an interval which deviates from the direction of the air inlet relative to the axis of the inner cavity of the shell; and a gap between the side wall of the shell positioned near the air inlet and the peripheral surface of the filter cartridge is greater than that between the side wall of the shell positioned near the opposite side of the air inlet and the peripheral surface of the filter cartridge. According to the air filter, the axis of the filter cartridge has the interval which deviates from the direction of the air inlet relative to the axis of the inner cavity of the shell, and when airflow enters from the air inlet, air is small in flow resistance and flows into the air filter easily due to large gaps, so that the problem of large flow resistance of the air due to small gaps between the filter cartridge and the shell of the air filter in the prior art is solved.
Description
Technical field
The utility model relates to air filter.
Background technology
In the prior art; Air filter is like Fig. 1, shown in 2, generally comprises housing 1 and is located at the filter core 2 of housing 1 cylindrical cavity, said housing inner chamber axis and 2 deads in line of said filter core; Said housing 1 side is provided with air inlet 3, is provided with gas outlet 4 in housing one end.In use, air gets into cleaner from air inlet, flows out from the gas outlet through behind the filter element filtering; But under the trend of air filter miniaturization; Air filter is done littler and littler, and the gap between filter core and the housing is more and more littler, and cause air cleaner flow resistance is increasing; Therefore can not improve under the situation of bigger air filter arrangement space at car load, how guarantee that the contradiction of long-life and low flow resistance of air filter is more and more outstanding.
Summary of the invention
The purpose of the utility model is to provide a kind of air filter, to solve the big problem of air flow resistance that occurs owing to the gap between air cleaner cartridge and the housing is little in the prior art.
In order to address the above problem; A kind of air filter of the utility model; Comprise the housing that contains cylindrical cavity and be located at the hollow cylinder filter core in the housing inner chamber; Said side is provided with air inlet, and the end face of said housing one end is provided with the gas outlet, the parallel axes of the axis of said filter core and said housing inner chamber; Said filter core axis has the spacing away from air inlet direction skew with respect to housing inner chamber axis, and described housing in the gap between near sidewall the air inlet and the filter core outer peripheral face greater than the gap of said housing between near sidewall the air inlet opposite side and filter core outer peripheral face.
Said air inlet is provided with air inlet pipe, and side and said side away from housing inner chamber axis on the said air inlet pipe are tangent.
The said filter core axis of the utility model has the spacing away from the skew of air inlet direction with respect to housing inner chamber axis; Make described housing in the gap between near sidewall the air inlet and the filter core outer peripheral face greater than the gap of said housing between near sidewall the air inlet opposite side and filter core outer peripheral face; Therefore when air-flow when air inlet gets into; Because the gap is big; So the little air inlet of air flow resistance is easy, solved the big problem of air flow resistance that occurs owing to the gap between air cleaner cartridge and the housing is little in the prior art.

The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is done detailed description:
A kind of embodiment of air filter; As shown in Figure 3; Comprise the housing 5 that contains cylindrical cavity and be located at the hollow cylinder filter core 6 in housing 5 inner chambers; Said housing 5 sides are provided with air inlet 7; Said air inlet 7 is provided with air inlet pipe 9, and side and said side away from housing 5 inner chamber axis on the said air inlet pipe 9 are tangent, on an end face of said housing 5, is provided with the gas outlet 8 with filter core 6 deads in line; Be connected with escape pipe 10 on the gas outlet; The parallel axes of the axis of said filter core 6 and said housing 5 inner chambers, said filter core 6 axis have the spacing away from air inlet 7 directions skews with respect to housing 5 inner chamber axis, and described housing 5 in the gap between near sidewall the air inlet 7 and filter core 6 outer peripheral faces greater than the gap of said housing 5 between near sidewall air inlet 7 opposite sides and filter core 6 outer peripheral faces.
In other embodiments, different with the foregoing description is that air inlet pipe can also be provided with along the housing radial direction on the said air inlet.
Claims (2)
1. air filter; Comprise the housing that contains cylindrical cavity and be located at the hollow cylinder filter core in the housing inner chamber; Said side is provided with air inlet; The end face of said housing one end is provided with the gas outlet; It is characterized in that: the parallel axes of the axis of said filter core and said housing inner chamber, said filter core axis has the spacing away from air inlet direction skew with respect to housing inner chamber axis, and described housing in the gap between near sidewall the air inlet and the filter core outer peripheral face greater than the gap of said housing between near sidewall the air inlet opposite side and filter core outer peripheral face.
2. a kind of air filter according to claim 1 is characterized in that: said air inlet is provided with air inlet pipe, and said air inlet pipe is tangent away from the side and the said side of housing inner chamber axis.
