Description of the drawings
Fig. 1 is the sectional view according to the air filter of one embodiment of the present of invention；
Fig. 2 is the structure diagram of the insertion piece of air filter shown in FIG. 1.
Specific embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, below in conjunction with the accompanying drawings to the present invention
Specific embodiment be described in detail.Many details are elaborated in the following description in order to fully understand this hair
It is bright.But the invention can be embodied in many other ways as described herein, those skilled in the art can be not
Similar improvement is done in the case of violating intension of the present invention, therefore the present invention is not limited to the specific embodiments disclosed below.
According to one embodiment of present invention, a kind of air filter is provided.As shown in Figure 1, the air filter packet
Include pot type housing 1, the filter medium 3 of tubulose and the insertion piece 2 of tubulose.Housing 1 is equipped with entrance 4 and outlet 5.The filtering of tubulose
Medium 3 is arranged in pot type housing 1, the inside of housing 1 is divided into be connected with entrance 4 be located at the tubular filtering medium 3
The first internal chamber and the second chamber being located at outside filter medium 3 being connected with outlet 5.Insertion piece 2 sets the first intracavitary, and
Preferably, the inner surface of the filter medium 3 of tubulose is used to support, can prevent filter medium 3 from caving in this way, and filtering is made to be situated between
Matter is uniformly distributed, so as to improve the service efficiency of filter medium.Entrance 4 is arranged on the top and bottom of pot type housing 1, outlet 5
It is arranged on the side of pot type housing 1.It will be understood by those skilled in the art that although the present embodiment middle casing 1 is pot type, it is somebody's turn to do
The shape of housing 1 is without being limited thereto, can be any other suitable shape.Similarly, as needed, filter medium 3 also may be used
To be any other suitable shape.In addition, as needed, the position of entrance 4 and outlet 5 can also do corresponding change, example
It such as exports 5 and is arranged on left side or downside, etc..As needed, entrance 4 can also only set top or bottom.
In the present embodiment, although insertion piece 2 is arranged in the first chamber inside the filter medium 3 of tubulose, ability
Field technique personnel are appreciated that in some embodiments insertion piece 2 can also be arranged on around tubular filtering medium 3 outside it.
In this case, the position of the entrance of filter and outlet and goes out with as shown in Figure 1 on the contrary, i.e. entrance is arranged on side
Mouth is arranged on top and bottom (or being provided only on top or bottom).That is, the first chamber being connected with entrance is located at the filtering of tubulose
The outside of medium, and the inside for being located at the filter medium of tubulose with exporting the second chamber being connected.
In the present embodiment, as shown in Fig. 2, the insertion piece 2 of tubulose includes multiple be mutually parallel and axially spaced setting
Load-bearing part 21, the load-bearing part 21 have annular load carrying face 211, annular load carrying face 211 is perpendicular to the axial direction of the insertion piece 2 of tubulose
Direction, and it is horizontally extending.The insertion piece 2 of tubulose further includes 4 ribs of the extension of direction along its longitudinal axis, 4 ribs with it is multiple
Load-bearing part 21 is connected to each other.Preferably, 4 ribs are evenly distributed on around annular load carrying face 211.Those skilled in the art can be with
Understand, the number of rib is not limited to 4.As needed, the shape of loading end 211 can also be changed accordingly, insertion piece 2
Shape be also not necessarily limited to be tubulose, can be rectangle or other suitable shapes.
In the present embodiment, loading end 211 is horizontally extending, it will be understood by those skilled in the art that loading end 211
It can also extend along other directions, but at least there is horizontally extending component.In some embodiments, loading end
211 can be rough surface, such as it for " V " font, zigzag or corrugated slot or has multiple with section
Recess, such slot and recess, increase loaded area and bearer cap, so as to carry more solid particles.At some
In embodiment, loading end 211 can be rough surface, it is preferable that roughness Ra>30, it is highly preferred that roughness Ra>60, it is larger
Roughness can increase the area of loading end, so as to deposit and carry more solid particles.In some embodiments, it holds
Section 211 can also have the function of to adsorb or adhere to solid particle, so as to more adhere to or adsorb, such as loading end
211 have adhesion layer, and from generating adhesive attraction or being made of plastics, plastic material appearance is easy to produce static electricity, so as to which easily absorption is empty
Solid particle in gas.
In the present embodiment, air enters the first chamber, cocurrent by being arranged on the two entrances 4 of filter top and bottom
Through tubular insert 2, so as to which the particle in air can be deposited and is carried on the surface of tubular insert 2, particularly carry
On face 211, then through tubular filtering medium 3, into the second chamber, finally from 5 outflow of outlet.As can be seen that by making in air
Particle deposit and be carried on the surface of tubular insert 2, particularly on loading end 211, and prevent its block tubular filter
Medium 3 can improve the dust containing capacity of air filter.In addition, it can also be seen that (i.e. air flows into close to entrance 4 from Fig. 2
One end) load-bearing part 21 central through hole aperture further away from the central through hole of entrance 4 (i.e. far from air flow into one end) hole
Diameter is big, i.e., is gradually reduced from the aperture of central through hole from the both ends of tubular insert 2 to centre, the purpose designed in this way be in order to
Coordinate gas distribution, increase loading end area.It will be understood by those skilled in the art that in the embodiment for only setting an entrance
In, such as only in the case of the top inlet porting of air filter, the aperture of the central through hole of load-bearing part 21 from entrance to
One end far from entrance is gradually reduced.
Such as preferred in above-described embodiment, the filtering dust which is used for vehicle fuel oil evaporation system for one
Device, specifically, the outlet of the air filter is connect with the canister suction inlet in vehicle fuel oil evaporation system.Since fuel oil steams
Dust filter in hair system has the characteristics that filtration flow-rate is low, sinks so as to be very beneficial for fixing particulate matter in the first chamber
It accumulates and is carried to the loading end, therefore, can achieve the effect that higher dust containing capacity improves.
Embodiment described above only expresses the several embodiments of the present invention, and description is more specific and detailed, but simultaneously
Cannot the limitation to the scope of the claims of the present invention therefore be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention
Protect range.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
