Abstract
The utility model discloses a kind of non-woven fabrics air filter filter core of novel inner support structure, non-woven fabrics filter layer and cocurrent and parallel that filter core is formed including two layers of square non-woven fabrics are laid in two metal strips of the relative inner of the two-layer nonwoven, two metal strips are fixed on the relative inner both sides of the two-layer nonwoven by sandwiched respectively, the non-woven fabrics filter layer and two metal strips are together folded into ripple glaze type, the thickness of the metal strip is 0.3~0.8mm, width is 1.5~2.5mm, and distance of the metal strip away from corresponding relative inner side edge is 4~6mm.The utility model in the inner side of two-layer nonwoven by increasing metal strip so that the structure after non-woven fabrics filter core folds remains unchanged, so as to avoid non-woven fabrics from loose situation occur after folding, saves plastic frame, enhances the fastness of non-woven fabrics.
Description
Technical field
The utility model belongs to engine aspirating system technical field, more particularly to a kind of nothing of novel inner support structure
Woven fabric air filter filter core.
Background technology
In recent years, with the lifting that people require for air filter filter element replacing mileage, non-woven fabrics filter core is because of its High dust holding amount
Characteristic be gradually widely used, but non-woven fabrics filter core does not allow foldable compared to paper filter core, causes non-woven fabrics filter core necessary
Plastic frame is coordinated to use, to fix non-woven fabrics filter core foldable structure.Filter core is fixed, it is necessary to using non-woven fabrics using plastic skeleton
Filter core and plastic frame one high-temperature injection technique, this technique has an impact non-woven fabrics characteristic, while complex process, filter core weight
Amount increase.
Utility model content
The utility model is in view of the problems of the existing technology and insufficient, there is provided a kind of non-woven fabrics of novel inner support structure
Air filter filter core.
The utility model is to solve above-mentioned technical problem by following technical proposals：
The utility model provides a kind of non-woven fabrics air filter filter core of novel inner support structure, its feature is that filter core includes
Non-woven fabrics filter layer and cocurrent and parallel that two layers of square non-woven fabrics forms are laid in the two of the relative inner of the two-layer nonwoven
Root metal strip, two metal strips are fixed on the relative inner both sides of the two-layer nonwoven, non-woven fabrics filtering by sandwiched respectively
Layer and two metal strips are together folded into ripple glaze type, the thickness of the metal strip is 0.3~0.8mm, width be 1.5~
2.5mm, distance of the metal strip away from corresponding relative inner side edge are 4~6mm.
It is preferred that one end of two metal strips is respectively and fixedly provided with the first buckle, close to corresponding gold on two metal strips
Belong to bar the other end position at be respectively and fixedly provided with this first buckle match second buckle, the non-woven fabrics filter layer and this two
After root metal strip is together folded into ripple glaze type, first buckle and the corresponding second buckle are interlockingly connected.
It is preferred that the metal strip is aluminum strip.
It is preferred that the thickness of the metal strip is 0.5mm, width 2mm.
It is preferred that distance of the metal strip away from corresponding relative inner side edge is 5mm.
On the basis of common knowledge of the art, above-mentioned each optimum condition, can be combined, up to the utility model respectively compared with
Good example.
The positive effect of the utility model is：
The utility model in the inner side of two-layer nonwoven by increasing metal strip so that the structure after the folding of non-woven fabrics filter core
Remain unchanged, so as to avoid non-woven fabrics from loose situation occur after folding, save plastic frame, enhance the firm of non-woven fabrics
Property.
Brief description of the drawings
Fig. 1 is the structure diagram of the non-woven fabrics air filter filter core of the utility model preferred embodiment.
Embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, those of ordinary skill in the art's all other embodiments obtained on the premise of creative work is not made, all belong to
In the scope of the utility model protection.
As shown in Figure 1, the present embodiment provides a kind of non-woven fabrics air filter filter core of novel inner support structure, filter core includes two layers
The non-woven fabrics filter layer and cocurrent and parallel of rectangular non-woven fabrics 1 (layer of non-woven fabric is shown in figure) composition are laid in this two layers
Two metal aluminum strips 2 of the relative inner of non-woven fabrics 1, two metal aluminum strips 2 are fixed on the two-layer nonwoven 1 by sandwiched respectively
Relative inner both sides, the non-woven fabrics filter layer and two metal aluminum strips 2 are together folded into ripple glaze type, the metal aluminum strip 2
Thickness be 0.3~0.8mm, width be 1.5~2.5mm, distance of the metal aluminum strip 2 away from corresponding relative inner side edge
For 4~6mm.
In the present embodiment, it is preferable that the thickness of the metal aluminum strip 2 is 0.5mm, width 2mm, and the metal aluminum strip 2 is away from right
The distance for the relative inner side edge answered is 5mm.
Moreover, one end of two metal aluminum strips 2 is respectively and fixedly provided with the first buckle 3, close to corresponding on two metal aluminum strips 2
Metal aluminum strip 2 the other end position at be respectively and fixedly provided with this first buckle 3 match second buckle 4, the non-woven fabrics mistake
After filtering layer and two metal aluminum strips 2 are together folded into ripple glaze type, first buckle 3 and corresponding second buckle 4 are interlockingly connected.
The utility model compares supporting network and the supporting form of hot melt adhesive, there is provided the filter area of bigger.It is overall to add
Folding forming is carried out after work, filter core can be made to obtain maximum adaptability.Using the plastic aluminum strip material of tool so that overall
Convenient formation, and after shaped alumina, there is good rigidity and stability of material, facilitate coordinate with filter casing if necessary
Assembling.
Although the foregoing describing specific embodiment of the present utility model, it will be appreciated by those of skill in the art that
