Description

Filter assemblies

Technical field

This utility model is related to a kind of filter assemblies.

Background technology

It is well known that usually through filter assemblies carrying out to dust-contained airflow in the product such as vacuum cleaner or air purifier Dust is removed, and the filter assemblies include framework and filter layer, and after a period of time, filter layer can become to block and need clear Reason or change, once and change will increase maintenance cost, filter layer is filtered frequently with single layer filter cotton, filter effect compared with Difference, life-span are shorter.Part producer proposes using reusable high efficiency filter component to reduce maintenance cost, such as by sea The filter assemblies of handkerchief form, although the component can be cleaned with water, are not washed clean clearly, and are unable to rapid airing, affect to use Family uses.Framework adopts duroplastss structure in addition, and its design is complex and relatively costly, and to realize that sealing coordinates, also Needs separately arrange sealing ring in framework, and sealing ring is easily lost in use, and this can affect the sealing of filter assemblies Energy.

Utility model content

This utility model purpose is：A kind of filter assemblies are provided, its simple structure, low cost and be capable of achieving washing and can weigh It is multiple to utilize.

First technical scheme of the present utility model is：A kind of filter assemblies, which at least includes：First filter layer, the second mistake Filtering layer, the 3rd filter layer and first and third filter layer is molded together and deformable flexible glue portion, wherein the second filter layer Between the first filter layer and the 3rd filter layer.

On the basis of above-mentioned technical proposal, following attached technical scheme is further included：

The strainability of second filter layer be more than first or the 3rd filter layer strainability.

First filter layer or the 3rd filter layer are lax sponge material, and the second filter layer is fine and close sponge or nonwoven Cloth material.

Several projections are provided with the surface of first filter layer and the 3rd filter layer.

The flexible glue portion includes inner ring, outer ring, several location holes being arranged on inner ring, between inner ring and outer ring Locating slot.

Strainability of the strainability of first filter layer less than or equal to the 3rd filter layer.

The projection of first filter layer is located at inlet side, and the projection of the 3rd filter layer is located at air side.

First filter layer, the second filter layer, the 3rd filter layer are washable material.

Second technical scheme of the present utility model is：A kind of filter assemblies, which at least includes：First filter layer, the second mistake Filtering layer, the 3rd filter layer and first and third filter layer is molded together and deformable flexible glue portion, wherein the second filter layer Between the first filter layer and the 3rd filter layer, wherein the first filter layer, the second filter layer, the 3rd filter layer are washable material Material, and several projections are provided with the surface of first filter layer or the 3rd filter layer.

This utility model advantage is：

This utility model simple structure, low cost and achievable washing simultaneously can be reused, life-span length, good filtration effect, Several projections for being arranged by both sides simultaneously, facilitate user to take.

Description of the drawings

Below in conjunction with the accompanying drawings and embodiment is further described to this utility model：

Fig. 1 is three-dimensional exploded view of the present utility model；

Fig. 2 is axonometric chart of the present utility model；

Fig. 3 is sectional view of the present utility model.

Specific embodiment

Embodiment：As Figure 1-3, this utility model provides a kind of specific embodiment of filter assemblies, and which at least wraps Include：First filter layer 10, the second filter layer 20, the 3rd filter layer 30, and by first and third filter layer 10,30 be molded together And deformable flexible glue portion 40, wherein the second filter layer 20 is located between the first filter layer 10 and the 3rd filter layer 30.

The strainability of the second filter layer 20 be more than first or the 3rd filter layer 10,30 strainability.First filter layer 10 or the 3rd filter layer 30 be lax sponge material, and the second filter layer 20 is the efficient filter material of fine and close sponge or non-woven fabrics etc. Material, wherein the first filter layer 10, or the second filter layer 20, or the 3rd filter layer 30 is conveniently of circular shape.

Several projections 12 for facilitating user to take are provided with the surface of the first filter layer 10 and the 3rd filter layer 30, And first filter layer 10 it is equivalently-sized with the 3rd filter layer 30, structure is identical, and strainability is identical, and with diameter greater than or be equal to the The diameter of two filter layers 20.Wherein projection 12 is used to increase air intake or air-out area, makes filter effect improve, can also use in addition It is portable, convenient for assembly.

Flexible glue portion 40 includes inner ring 42, outer ring 44, several location holes 420 being arranged on inner ring 42, positioned at inner ring 42 The edge of the first filter layer 10 and the 3rd filter layer 30 is glued by locating slot 46 and outer ring 44 between and in a ring, wherein inner ring 42 It is combined, location hole 420 is used for mould positioning in the production of filter assemblies to be needed, and locating slot 46 is used for and vacuum cleaner Or the flange of air purifier is engaged.

First filter layer 10 is used for the filtration of larger impurity, and the second filter layer 20 is used for the filtration of fine dirt, the 3rd mistake Filtering layer 30 is then the filtration again to air-flow.

This utility model life-span length, low cost, process is simple, good filtration effect, while several arranged by both sides Projection, facilitates user to take.

Certainly above-described embodiment its object is to allow and be familiar with this only to illustrate technology design of the present utility model and feature The people of technology will appreciate that content of the present utility model and implements according to this, can not limit protection model of the present utility model with this Enclose.Equivalent transformation or modification that all spirit according to this utility model main technical schemes are done, all should cover in this reality Within new protection domain.
