Description

Washable air filter element module

Technical Field

The utility model relates to a gauze mask filter core technical field specifically belongs to a washable air filter module.

Background

In recent years, the trend that air pollution is serious is controlled, but haze still frequently appears in some areas, and harm is brought to respiratory systems and body health of people. More antifog haze gauze mask has appeared in the market at present, and its haze filter layer mainly uses electret melt-blown cloth, adopts corona discharge's mode, thereby makes ordinary melt-blown cloth have the electric charge to improve the entrapment and the filtration to the particle, and this kind of material exists the shortcoming that can not the washing, and in case after the washing, the electric charge that it had disappears, completely loses basically to the filter effect of haze.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a but air filter module of washing overcomes the problem that the antifog haze gauze mask among the prior art can not wash.

In order to solve the above problems, the utility model adopts the following technical proposal:

the washable air filter element module comprises hydrophobic fabrics and filtering materials, wherein the filtering materials are located between the two hydrophobic fabrics, the hydrophobic fabrics and the filtering materials form a mask-shaped composite fabric, the periphery of the composite fabric is wrapped with hydrophobic cloth, and the hydrophobic cloth is sewn around the composite fabric through hydrophobic fibers.

Furthermore, the filtering material is an anti-haze acetate fiber filtering material or electret melt-blown cloth.

Furthermore, an activated carbon fiber fabric is arranged between the filtering material and one of the hydrophobic fabrics.

Furthermore, the hydrophobic fabric and the hydrophobic cloth are woven by polyurethane fibers with super-hydrophobic capacity.

Further, the hydrophobic fiber is a polyurethane fiber with super-hydrophobic capability.

Compared with the prior art, the utility model discloses an implement the effect as follows: the filtering material and the activated carbon fiber fabric in the air filter element module are wrapped by the hydrophobic fabric and the hydrophobic cloth, the module is used for the haze-preventing mask, when the mask is cleaned, the hydrophobic fabric can prevent water from contacting the filtering material, and the filtering material is prevented from being damaged by the water; in addition, the hydrophobic fabric in the module is woven by polyurethane fibers with super-hydrophobic capacity, and the module has air permeability, so that air can penetrate through the hydrophobic fabric, and the filtering material can filter haze particles; and the activated carbon fiber fabric can adsorb haze particles in partial air, so that the filtering effect of the module on the haze particles is improved.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation to be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

As shown in fig. 1-3, a washable air filter module, including hydrophobic surface fabric 11 and filtering material 13, hydrophobic surface fabric 11 is by the polyurethane fiber textile who has super hydrophobic ability, and the polyurethane fiber who has super hydrophobic ability uses the super hydrophobic polyurethane fiber of Suzhou lianchang specialty fiber limited company production, and filtering material 13 is antifog haze acetate fiber filtering material 13 or electret meltblown.

The filtering material 13 is positioned between the two hydrophobic fabrics 11, the hydrophobic fabrics 11 and the filtering material 13 form a composite fabric 1 in a mask 4 shape, the periphery of the composite fabric 1 is wrapped with hydrophobic cloth 2, the hydrophobic cloth 2 is sewn around the composite fabric through hydrophobic fibers 3, and the hydrophobic fibers 3 are polyurethane fibers with super-hydrophobic capability.

The hydrophobic fabric 11 and the hydrophobic cloth 2 in the module are woven by polyurethane fibers with super-hydrophobic capacity, have hydrophobicity and air permeability, and enable air to penetrate through the hydrophobic fabric 11 and the filtering material 13 to filter haze particles; when this module was arranged in antifog haze gauze mask 4, with this module setting in using the gauze mask 4 that soft cotton fiber cloth sewed up originally internally, make this module separate with the external world through cotton fiber cloth, the gas permeability of cotton fiber cloth is better, can not influence the gas permeability of this module. The filtering material 13 and the activated carbon fiber fabric 12 in the air filter element module are wrapped by the hydrophobic fabric 11 and the hydrophobic cloth 2, and when the mask 4 is cleaned, the hydrophobic fabric 11 can prevent water from contacting the filtering material 13, so that the filtering material 13 is prevented from being damaged by the water.

In addition, in order to improve the filtering effect of the module on haze particles, an activated carbon fiber fabric 12 is further arranged between the filtering material 13 and one of the hydrophobic fabrics 11, the activated carbon fiber fabric 12 is made of activated carbon fiber cloth produced by special activated carbon fiber fabric 12 limited of Jiangsu Tongkang, and the activated carbon fiber fabric 12 can absorb some haze particles in the air.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
