Description
Technical field
The present invention relates to a kind of filtering consumptive material of dust catcher, and in particular to a kind of disposable sea for hand held cleaner
Pa.
Background technology
Extra large pa, it is HEPA transliteration, HEPA is a kind of efficient filtering material, may filter that the fine particle in air, subtracts
Small secondary pollution.It is well known that extra large pa is the part that a kind of very important high frequency time uses in dust catcher, but for cost
The factors such as control, each manufacturer is slow for the research and development progress of more high-quality and efficient extra large pa, but existing extra large pa makes
After a period of time, in particular for now more and more popular small size type dust catcher, such as hand held cleaner, easily occur
Block, cause dust catcher air draft not smooth, cause motor temperature to raise, so as to have a strong impact on the life-span of motor；Or some
Dirt bag exhaust effect can manage it, but bad to the filter effect of dust, cause fine dusts in the presence of big wind-force, through dirt bag
Dust catcher is discharged, so as to cause secondary pollution to indoor environment, has had a strong impact on the respiratory health of human body.Meanwhile filter effect
Poor extra large pa can also influence the working environment of miniature motor, fine dust is crept into motor, so as to influence motor
Normal work.
The content of the invention
In view of the deficiencies of the prior art, it is an object of the invention to provide a kind of for the disposable of hand held cleaner
Extra large pa, its is simple in construction, and windage is low, not laying dust congestion, and function free of cleaning can be achieved.
Technical scheme is summarized as follows：
A kind of disposable extra large pa for hand held cleaner, including glass layer, modified fibre layer and spongy layer, its
In, the modified fibre layer includes the material of following parts by weight：
Propylene-the parts by weight of vinyl acetate copolymer filament 40~80；
The parts by weight of CUP silk 20~60.
Preferably, the described disposable extra large pa for hand held cleaner, wherein, the modified fibre layer includes following
The material of parts by weight：
Propylene-the parts by weight of vinyl acetate copolymer filament 50~70；
The parts by weight of CUP silk 30~50.
Preferably, the described disposable extra large pa for hand held cleaner, wherein, the propylene-vinyl acetate is common
In polymer fibre silk, propylene content accounts for 15~55wt%, and remaining is vinyl acetate.
Preferably, the described disposable extra large pa for hand held cleaner, wherein, the propylene-vinyl acetate is common
The number-average molecular weight of polymer fibre silk is 15000~20000.
Preferably, the described disposable extra large pa for hand held cleaner, wherein, the propylene-vinyl acetate is common
In polymer fibre silk, propylene content accounts for 30~40wt%, and remaining is vinyl acetate.
Preferably, the described disposable extra large pa for hand held cleaner, wherein, the propylene-vinyl acetate is common
The number-average molecular weight of polymer fibre silk is 16000~17000.
Preferably, the described disposable extra large pa for hand held cleaner, wherein, the modified fibre layer also includes 10
The sisal fiber of~12 parts by weight.
The beneficial effects of the invention are as follows：This case is by the improvement to conventional extra large pa structure and material, by introducing propylene-second
Vinyl acetate copolymer filament and CUP silk, strainability of the extra large pa under small space is improved, reduces extra large pa
Windage, meanwhile, the modified layer of introducing can be effectively improved the air current flow stability in dust catcher air channel, can improve filter dirt effect,
Protect the core component in small micro-cleaner；Further, since propylene draws in propylene-vinyl acetate copolymer filament
Enter and the introducing of sisal fiber, improve the anti-laying dust ability of extra large pa so that extra large pa possesses function free of cleaning.
Embodiment
With reference to embodiment, the present invention is described in further detail, to make those skilled in the art with reference to specification
Word can be implemented according to this.
This case proposes the disposable extra large pa for hand held cleaner of an embodiment, including glass layer, modified fibre
Layer and spongy layer, wherein, the modified fibre layer includes the material of following parts by weight：
Propylene-the parts by weight of vinyl acetate copolymer filament 40~80；
The parts by weight of CUP silk 20~60.
Propylene-vinyl acetate copolymer filament not only has the excellent rigidity and weatherability of polyvinyl acetate,
Due also to the modification of propylene, improves filametntary toughness, filametntary impact strength is added, improves the anti-product of extra large pa
Dirt ability so that extra large pa possesses function free of cleaning.CUP silk and propylene-vinyl acetate copolymer filament mixes make
With rear, the windage for reducing extra large pa can be cooperateed with, and meet demand free of cleaning.
As the another embodiment of this case, wherein, modified fibre layer preferably includes the material of following parts by weight：
Propylene-the parts by weight of vinyl acetate copolymer filament 50~70；
The parts by weight of CUP silk 30~50.
Research is found, when the addition to propylene-vinyl acetate copolymer filament and CUP silk enters traveling one
After step limits, more excellent filter effect and lower initial resistance can be obtained.
As the another embodiment of this case, wherein, in propylene-vinyl acetate copolymer filament, propylene content accounts for 15~
55wt%, remaining is vinyl acetate.Research is found, after the proportioning to propylene and vinyl acetate is defined, can make sea
Pa obtains more preferably performance.
As the another embodiment of this case, wherein, the filametntary number-average molecular weight of propylene-vinyl acetate copolymer is
15000~20000.Research is found, after being defined to the filametntary number-average molecular weight of propylene-vinyl acetate copolymer,
Outstanding strainability and lower windage can be obtained, therefore, its number-average molecular weight should be limited.
As the another embodiment of this case, wherein preferably, in propylene-vinyl acetate copolymer filament, propylene content
30~40wt% is accounted for, remaining is vinyl acetate.Research finds, when further limiting the proportioning of propylene and vinyl acetate
After fixed, extra large pa can be made to obtain optimal performance.
As the another embodiment of this case, wherein, the filametntary number-average molecular weight of propylene-vinyl acetate copolymer is preferably
16000~17000.Research finds, when further limiting the filametntary number-average molecular weight of propylene-vinyl acetate copolymer
After fixed, extra large pa can be made to obtain most outstanding strainability and minimum windage.
As the another embodiment of this case, wherein, modified fibre layer also includes the sisal fiber of 10~12 parts by weight.Sisal hemp is fine
Wesy when that is, air-flow hits extra large pa, due to air draft not in time, can cause portion gas adverse current in the contrary wind phenomenon for improving extra large pa,
So as to which easily to small size dust catcher, i.e., the air channel inside hand held cleaner produces interference, causes air turbulence, cause motor
Gathered Deng kernel component heat.Sisal fiber can also increase the smoothness of modified fibre layer, to reduce the product of modified fibre layer
Dirt rate.
Table one lists the performance test of the major parameter and obtained extra large pa of modified fibre layer in the extra large pas of different embodiments
Data：
Table one
Although embodiment of the present invention is disclosed as above, it is not restricted in specification and embodiment listed
With it can be applied to various suitable the field of the invention completely, can be easily for those skilled in the art
Other modification is realized, therefore under the universal limited without departing substantially from claim and equivalency range, it is of the invention and unlimited
