Abstract

The utility model provides an efficient dustproof filter disc of a haze-preventing mask. The efficient dustproof filter disc comprises an efficient composite HEPA filter net and a stainless steel screen. The efficient composite HEPA filter net and the stainless steel screen are of an overlapped structure, and the efficient composite HEPA filter net and a PVDF film are fixed through cotton threads which are arranged on the periphery. The efficient dustproof filter disc of the haze-preventing mask can be directly placed in a common mask so that the common mask can be used as the haze-preventing mask.

Description

A kind of anti-haze mouth mask efficient dustproof filter disc

Technical field

The utility model relates to a kind of amenities, particularly a kind of anti-haze mouth mask efficient dustproof filter disc.Can effectively to PM2.5 and pollen etc., protect.

Background technology

Mouth mask, as a kind of daily protective articles, can effectively filter out harmful visible or sightless material.Along with air pollution problems inherent becomes increasingly conspicuous, the quality of mouth mask performance is also more and more important.Common air particles has grit, dust, sub-micron dust, spray dust, drips, cigarette, chemical fumes, coal smoke etc.PM2.5 is the important indicator of observing and controlling air pollution degree, refers in particular to fine particle.Fine particle refers to that diameter in air is equal to or less than the particle of 2.5 μ m, can directly be sucked in human body bronchus, disturbs pulmonary gases exchange, causes the diseases such as asthma, bronchitis and cardiovascular disease.With mouth mask, stop that it is a kind of simple method that these air particles enter human body.Anti-dust respirator is mainly used in preventing dust, effective when stopping larger particulate, but its particle barriering effect that is less than 5 μ m for diameter is very limited, and antibacterial ability a little less than; Operation mouth mask is manufactured by three layers of nonwoven, is applicable to operating room environment, can intercept particulates more than diameter 4 μ m; Active carbon mask has added adsorbent-active carbon, the effective pernicious gas such as the benzene in absorbed air, formaldehyde, but cannot effectively intercept for PM2.5, in addition, active carbon itself is exactly a kind of particle, by wearer, is sucked also and can work the mischief to human body.

HEPA filter screen is a kind of internationally recognized best high-efficiency filtering material, and initial HEPA is applied to nuclear energy research protection, is widely used in the place that accurate laboratory, medicine production, atom research and operation etc. need high-cleanness, high.HEPA is interwoven by very tiny organic fiber, and stronger to the capturing ability of particulate, aperture is small, and adsorption capacity is large, and purification efficiency is high, and possesses water imbibition, for the particle purifying rate of 0.3 micron, is 99.97%.That is to say: in every 10000 particles, can only have 3 particles can penetrate HEPA filter membrane.Therefore, the effect of its filtration of particulate matters is very obvious, if use its filter cigarette, the effect of filtering so almost can reach 100%, because the particle size in cigarette, between 0.5-2 micron, cannot be passed through HEPA filter membrane.

CN203341039 disclose a kind of functional protective mask by interior, in, outer three layers form.Internal layer and outer what use is that the photochemical catalyst that reassembled into by apatite and the nano titania nonwoven after antibacterial, antifouling processing is processed forms.Middle level is used calcium carbide fiber or bamboo-carbon fibre as filter course, makes functional protective mask have absorption, decomposition and barrier functionality.Functional mouth mask, except can effectively protecting PM2.5 and pollen etc., when epidemic disease, infectious disease, variability influenza occur, also can effectively stop interpersonal mutual infection.

CN101912168 discloses a kind of tool ecological fiber anti-dust respirator, and the mask cup body that it is made by chemical fibre synthetic material and at least one deck ecological fiber layer form; Described ecological fiber layer is compounded in spherical inner wall, outer wall or the intermediate layer of mask cup body; In the spherical inner wall of body, there is a plurality of point-like or string beading joint, at the margin of optic cup of mask cup body, there is a lap welding joint; Because comprising the various ecological fibers with high-hygroscopicity, perspire, bacteriostasis antibiosis such as bamboo fibre, bamboo carbon fibre, flaxen fiber, fibre and soya, makes compound fabric, therefore can meet under the prerequisite of effectively filtering, solve the problem of perspiration and bacterium, be natural fabric with people's contact level simultaneously, can not produce allergy.

Existing document and patented technology adopt the fibrous material with adsorption function and sterilizing function mostly, and after repeatedly washing is used, through the processing of washing agent, the adsorption function of fiber surface and sterilizing function can reduce gradually, have reduced the service life of mouth mask.

Summary of the invention

The purpose of this utility model is the defect that overcomes prior art, and a kind of convenient filling, advantages of good adsorption effect are provided, can wash fast anti-haze mouth mask efficient dustproof filter disc.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows: anti-haze mouth mask efficient dustproof filter disc, comprise that composite highly effective HEPA filter screen and stainless steel cloth form, described composite highly effective HEPA filter screen and stainless steel cloth form structure in an overlapping, and use cotton thread to be fixed together in surrounding and pvdf membrane.

Composite highly effective HEPA filter screen of the present utility model is commercially available prod, as the product of the Dongguan purifying Science and Technology Ltd. of friend.

Pvdf membrane of the present utility model is commercially available prod, as Shanghai Mei Wei plastic cement Co., Ltd product.

Stainless steel cloth material of the present utility model is 304 or 316 stainless steels, model 50-100 order.

Compared with prior art, the utility model has the advantage of:

Anti-haze mouth mask efficient dustproof filter disc of the present utility model, simple in structure, filter efficiency is high, can simply put into common mouth mask and use, easy to use, and can effectively remove PM2.5 particle, and can not reduce result of use through long-time washing.
