Abstract
The utility model gives a kind of air filter, including housing and filter core, chamber is provided with housing, air inlet and gas outlet are provided with housing, filter core is arranged in chamber, and the gas outlet that air sequentially passes through the air inlet of housing, the chamber of housing, filter core and housing constitutes the filtration channel that air passes through；Air inlet is arranged on the side wall of housing, and housing sidewall is outward extended with air inlet pipe along air inlet edge, and the center line of air inlet pipe is non-intersect with casing centerline.Air enters in housing along the centerline direction of air inlet pipe, because the center line of air inlet pipe is non-intersect with casing centerline, air enters in housing cavity, annular airflow is formed between filter core and housing, the contact area of increase air and filter core, and air into the direct area for colliding filter core after chamber is reduced, the filter effect of filter core is improved.
Description
Technical field
The utility model is related to a kind of air filter.
Background technology
The device of the granulometric impurity in air is removed, when engine works, if containing the impurity such as dust in suction air
To just the abrasion of part be aggravated, so air filter must be equipped with, existing air filter is by filter core, blade ring and housing
Composition, the air admission hole alignment filter core center of normal air cleaner, air directly clashes into filter core after entering housing, after a period of time
The clean-up effect of air filter is influenceed, and air cannot form circulation in housing, it is impossible to fully contacted with filter core.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of air filter rational in infrastructure, easy for installation.
In order to solve the above technical problems, the utility model provides a kind of air filter, including housing and filter core, housing
Chamber is inside provided with, air inlet and gas outlet are provided with housing, filter core is arranged in chamber, and air sequentially passes through the air inlet of housing
The gas outlet of mouth, the chamber of housing, filter core and housing constitutes the filtration channel that air passes through；
Air inlet is arranged on the side wall of housing, and housing sidewall is outward extended with air inlet pipe, air inlet pipe along air inlet edge
Center line it is non-intersect with casing centerline.
After such structure, air enters in housing along the centerline direction of air inlet pipe, due to the center of air inlet pipe
Line is non-intersect with casing centerline, and air enters in housing cavity, and annular airflow is formed between filter core and housing, increases air
With the contact area of filter core, and air into the area that filter core is directly collided after chamber is reduced, improve the filter effect of filter core.
This air filter gas outlet is arranged on the end face of housing, and housing end face extends internally out along gas outlet edge
Tracheae, escaping pipe is provided with internal thread；After such structure, the engine intake passage of the internal thread of escaping pipe and outside it
Between be directly connected through a screw thread fixation, eliminate the mounting seat of air filter in the prior art, reduce this air filter
Shared volume.
Filter paper of this air cleaner cartridge from star irradiation structure；After such structure, star irradiation structure
Filter paper be remarkably improved the filter effect of filter core compared to common filter paper.
Fixed seat is fixedly connected with the chamber of this air filter housing, is provided with fixed seat and fixing bolt cooperation
Through hole, fixing bolt sequentially passes through the through hole of fixed seat, filter core, and be fixed on filter core in chamber by fixing bolt；Using such
After structure, the position of filter core is fixed in fixed seat and fixing bolt cooperation.
The housing of this air filter includes upper end cover, outer tube and bottom end cover, and air inlet is arranged on outer tube, and gas outlet sets
Put on bottom end cover；After such structure, the structure of housing is more reasonable.
Brief description of the drawings
Fig. 1 is the structural representation of this air filter embodiment.
Fig. 2 is the top view of Fig. 1.
Specific embodiment
As shown in Fig. 1 to 2
This air filter includes housing and filter core 2.
Housing is generally cylindrical, and housing includes upper end cover 11, outer tube 12 and bottom end cover 13, upper end cover 11, the and of outer tube 12
Bottom end cover 13 is placed from top to bottom, and upper end cover 11 and bottom end cover 13 are welded and fixed with outer tube 12 respectively, and chamber 16 is provided with housing.
Air inlet 14a and gas outlet 15a is provided with housing, air inlet 14a is arranged on the side wall of outer tube 12 of housing, outer tube
12 side walls are outward extended with air inlet pipe 14 along air inlet 14a edges, and air inlet pipe 14 is one end straight tube, but air inlet pipe 14 center line
Housing end face projection not in housing in the radial direction, i.e. the extended line of the center line of air inlet pipe 14 and casing centerline not phase
Hand over；
Gas outlet 15a is arranged on the bottom end cover 13 of housing, and bottom end cover 13 extends internally along gas outlet 15a edges outlet
Pipe 15, escaping pipe 15 is provided with internal thread.
Filter core 2 is arranged in chamber 16, and the upper end of filter core 2 is resisted against on the upper end cover 11 of housing, the lower end of filter core 2 against
On the bottom end cover 13 of housing, there is gap between the side wall and the madial wall of outer barrel of filter core 2, filter core 2 radiates knot from star
The filter paper of structure.
Fixed seat 3 is welded with chamber 16, fixed seat 3 is in the outside of escaping pipe 15, fixed seat 3 with the welding position of housing
To being stretched out inside chamber 16, the through hole coordinated with fixing bolt 4 is provided with fixed seat 3, fixing bolt 4 sequentially passes through fixed seat 3
Through hole, filter core 2, be fixed on filter core 2 in chamber 16 by fixing bolt 4.
Air sequentially passes through the air inlet 14a of housing, the gas outlet 15a of the chamber 16, filter core 2 and housing of housing constitutes sky
The filtration channel that gas passes through.
Above-described is only a kind of implementation method of the present utility model, it is noted that for the ordinary skill of this area
For personnel, on the premise of the utility model principle is not departed from, some variations and modifications can also be made, these also should be regarded as
Belong to protection domain of the present utility model.
