Abstract

The utility model relates to a cellulose filter element and a mask thereof. The cellulose filter element is formed by overlapping at least two layers of cellulose filter films, wherein the cellulose filter films have micro-hole structures and pore structures; the mask comprises at least two layers of gauze and a lacing; the cellulose filter element is placed between the gauze. By adopting the cellulose filter element, dust particles can be effectively filtered and blocked, the defects of poor dust particle filtering effect, generation of new pollution and ineffectiveness to harmful gas and particles in the conventional filter element are overcome, and the practical requirements are met.

Description

A kind of cellulose filter disc and mouth mask thereof
Technical field
The utility model belongs to natural polymer filtering material technical field, relates to a kind of filter disc, relates in particular to a kind of gray haze particle, cellulose filter disc and mouth mask thereof for the replaceable interlayer of mouth mask of filtering.
Background technology
In recent years, China has broken out in many areas lasting gray haze and has polluted, and the protective articles demands such as mouth mask, air purifier increase considerably, but more traditional mouth mask adopts multilayer common fabric to make and form, and cannot filter the pellet in gray haze.Because contain a large amount of PM2.5 particles in gray haze, PM2.5 refers to that in atmosphere, diameter is less than or equal to the particle of 2.5 microns, PM2.5 particle diameter is little, be rich in a large amount of poisonous and harmful substances, and its time of staying in atmosphere is long, fed distance is far away, so very large on the impact of health and atmosphere quality.And the cotton of existing common mouth mask can not effectively filter obstruct gray haze particle, fast-selling anti-haze mouth mask filter disc mainly contains three types recently: the one, and multi-layer nonwoven fabrics mouth mask; The 2nd, add active carbon filtering layer; The 3rd, bactericidal nano-silver processing; Other filter discs also have these three kinds of methods are combined; But because can not effectively filtering as the cotton of common mouth mask, multi-layer nonwoven fabrics mouth mask intercepts gray haze particle, the fine particle of active carbon can produce again new pollution, bactericidal nano-silver processing can only be killed bacterium, its for pernicious gas and particle without any effect, therefore, need one can solve effective filtration and intercept gray haze particle issues, and can overcome above-mentioned existing filter disc and have to filter and intercept gray haze particle weak effect, can produce new pollution, and to pernicious gas and the invalid defect of particle, meet the needs of actual conditions.
Utility model content
The purpose of this utility model is, a kind of cellulose filter disc and mouth mask thereof are provided, intercept gray haze particle issues to solve effective filtration, and overcome above-mentioned existing filter disc and have to filter and intercept gray haze particle weak effect, can produce new pollution, and to pernicious gas and the invalid defect of particle, meet the needs of actual conditions.
For achieving the above object, the utility model provides on the one hand a kind of cellulose filter disc, is overlapped by two layers of cellulose filter membrane at least, and described cellulose filter membrane has microcellular structure and pore structure.
Described pore structure is preferably dimensioned to be and is greater than microcellular structure.
The quantity of described microcellular structure is preferably more than the quantity of pore structure.
When described cellulose filter membrane is overlapping, its pore structure is preferably mutually and does not overlap.
Described cellulose filter membrane is preferably rectangle sheet.
The length of its rectangle sheet of described cellulose filter membrane is preferably 16-25cm, is highly preferably 10-16cm.
The diameter of described its microcellular structure of cellulose filter membrane is preferably 100-200nm.
The length of described its pore structure of cellulose filter membrane is preferably 50-200 μ m.
For achieving the above object, the utility model provides a kind of mouth mask on the other hand, comprises at least two-layer gauze and frenulum, is preferably and is placed with above-mentioned cellulose filter disc between described gauze.
The insertion that described cellulose filter disc is preferably changeable type is set between described gauze.
Compared with prior art, the utlity model has following advantage:
Cellulose filter disc of the present utility model and mouth mask thereof, the filter membrane that its cellulose filter disc has micropore and gap structure by multilayer overlaps, and can effectively filter in gray haze inhalable particles harmful in adsorbable filtered air; Cellulose is as natural polymer product, have advantages of nontoxic, green, pollution-free and cheap and easy to get, and this cellulose filter membrane does not dye, nothing interpolation, formaldehydeless, pollution-free, and detachable replacement, has farthest ensured the protective effect to people in haze environment simultaneously; This filter disc can disposablely use, and as 10 days, guarantees hygiene and health, after discarding, is degraded into organic matter and water, free from environmental pollution, environmental protection and saving; Insertable cellulose filter disc is set between the gauze of its mouth mask, and that can effectively filter gray haze can suction-type particle; Can solve effective filtration and intercept gray haze particle issues, and overcome above-mentioned existing filter disc have filter intercept gray haze particle weak effect, can the new pollution of generation, and to pernicious gas and the invalid defect of particle, meet the needs of actual conditions.
