Abstract
The utility model provides a kind of filter element comprising：Multiple filtering monomers, Z-shape folding connection, abutment end are connected with rubber belt sealing；Papery outline border is preferably rectangular-shape, and two opposite faces are in open shape, to be tightly connected respectively by viscose as air intake vent and air outlet, remaining four sides and four sides of multiple filtering monomer.The utility model greatly simplifies procedure of processing, can save material, reduces weight and structural drag, is finished and throws, and is suitable for secondary filtration, air purifier and the air cleaning system of fresh air purifying.
Description
Technical field
The utility model is related to a kind of air filter, more particularly to a kind of low-resistance, the filter element without inside casing.
Background technology
Be commonly used on the market ventilation, air-conditioning, purification system folding shape filter element, as shown in Figure 1, being in metal
It is welded with inner metal bezel 2 in outline border 1, then the filtering monomer 3 for folding shape is installed, is sealed in inner metal bezel 2.This device ratio
The filter resistance that folding is only formed in outline border is small.
It often to be replaced since filter belongs to consumables, and the device of this metal outer frame 1, inner metal bezel 2 can only be complete
It abandons, there is the serious wastings of resources.
It is not easy good match between the filtering monomer 3 due to folding shape connection again, the advantage for keeping its resistance small is from abundant
It plays.
Utility model content
The purpose of this utility model is to provide a kind of filter element, reduces cost, and makes the resistance of folding shape filter element
The small advantage of power is played completely.
To achieve the above object, the technical solution adopted in the utility model is：
A kind of filter element, it is characterized in that including：
Multiple filtering monomers, Z-shape folding connection, abutment end are connected with rubber belt sealing；
Papery outline border has air intake vent and air outlet, and is tightly connected with the side of multiple filtering monomer.
The filter element, wherein：The adhesive tape is kraft paper gummed tape.
The filter element, wherein：The papery outline border is in a rectangular parallelepiped shape.
The filter element, wherein：Two opposite faces of the papery outline border are in open shape, using as the air intake vent
With the air outlet, remaining four sides and four sides of multiple filtering monomer are tightly connected by viscose respectively.
Compared with prior art, the utility model greatly simplifies procedure of processing, can save material, reduce weight with
Structural drag is finished and throws, and is suitable for secondary filtration, air purifier and the air cleaning system of fresh air purifying.
Description of the drawings
Fig. 1 is the existing internal structure schematic diagram for folding shape filter element；
Fig. 2 is the internal structure schematic diagram of filter element provided by the utility model.
Reference sign：Metal outer frame 1；Inner metal bezel 2；Filter monomer 3；Adhesive tape 4；Papery outline border 5；Fold spacing a；
Depth b；Thickness c.
Specific implementation mode
The utility model offer is a kind of can to eliminate filter element to greatest extent by theoretical calculation and testing and verification proof
Structural drag (filtering material resistance is intrinsic) without the bonded filter element of inside casing, as shown in Fig. 2, having：
Multiple filtering monomers 3, Z-shape folding connection, abutment end are tightly connected with adhesive tape 4 (preferably kraft paper gummed tape)；
In manufacturing process, as long as the both ends adhesive tape 4 of the filtering monomer 3 stacked is sticked, then is pulled open from both sides, just naturally form Z
Shape folds the form of connection；
Papery outline border 5, is preferably rectangular-shape, and two opposite faces (left side and the right side in figure) are in open shape, using as
Air intake vent and air outlet, remaining four sides (front in figure, below, top surface and bottom surface) and four sides of multiple filtering monomer 3 are distinguished
It is tightly connected by viscose (being unillustrated).
As shown in Fig. 2, the depth of the papery outline border 5 is b, the folding spacing of filtering monomer 3 is a, filters the thickness of monomer 3
Degree is c, and the utility model compared with prior art, due to eliminating inner metal bezel 2, is limited in same depth b and thickness c
Under, smaller can be accomplished by folding spacing a, to improve filter material capacity, and fold spacing a, depth b and thickness by suitably adjusting
The relationship of c can greatly reduce the structural drag of filter element.With a height × width for 400mm × 400mm, thickness 200mm
Filter element for, the structural drag of the utility model is only conventional 1/5, and correspondingly service life is conventional 5 times.
In addition, the utility model no longer needs metal material, material cost to substantially reduce, replacement when, is abandoned also not entirely
Unfortunately.
In short, the utility model greatly simplifies procedure of processing, material can be saved, reduces weight and structural drag,
It is finished and throws, be suitable for secondary filtration, air purifier and the air cleaning system of fresh air purifying.
It is described above to be merely exemplary for the utility model, and not restrictive, those of ordinary skill in the art
Understand, in the case where not departing from spirit and scope defined by claim, can many modifications may be made, variation or it is equivalent, but
It falls within the scope of protection of the utility model.
