Abstract
Disclosed is a dustproof mask, which comprises two components of a mask body and a filtration part that connect and compact with each other, the utility model is characterized in that the filtering layer in the filtration part adopts the nuclear track membrane having a precision aperture and an aperture density, impurities such as solid particles in the gas can be stopped on the surface of the membrane to receive the filtering and purifying by the filtration function of the nuclear micro-porous, the mask has advantages of high dustproof rate, not easy to plug, intensity, easy to cleaning and reusability.
Description
This utility model belongs to the health treatment technical field, relates in particular to a kind of novel anti-dust respirator.
The filtering layer of existing anti-dust respirator is many to be formed with materials such as tunica fibrosa or nonwoven, is characterized in that rete is thick, and the filtering layer aperture is long and irregular, thereby easily stops up, pollutes, and should not clean and reuse.
The purpose of this utility model is to adopt novel filtering layer material to design a kind of durable and efficient anti-dust respirator.
The utility model is realized by following proposal:
A kind of anti-dust respirator is made up of mouth mask body 6 and filtration members 7, it is characterized in that: filtration members 7 is by shell 1, seal 2, and filtering layer 3, supporting network 4 and pad 5 are formed; Seal 2 is a tabular, and filtering layer 3 adopts has the nucleopore membranes of precision aperture and hole density, and this filter membrane is tiled on the supporting network 4 of porous, holds supporting network 4 with pad 5 at last; The inner surface of shell 1 and mouth mask body 6 connection places have screw thread, and mouth mask body 6 spins with filtration members 7 and compresses.
The filtering layer 3 of filtration members 7 can be used the reinforcement nucleopore membranes of metal-plated membrane layer.
The material of mouth mask body 6 and filtration members 7 is plastics or rubber, and supporting network 4 is the available metal net also.
Can a filtration members 7 respectively be installed one of center installation or at left and right side on the mouth mask body 6.
The utility model is based on and uses this high-tech product of nucleopore membranes, and the filter course of doing in the anti-dust respirator is made, because this film has accurate aperture (can from several microns to two, 30 microns) and hole density (10
4-10
8/ cm
2), the micropore shape approximation is cylindric, regular homogeneous, and, make the longitudinal length of micropore shorter because of thickness only is about 20 microns, and can be trapped in the filter membrane surface to all dust particles, and be difficult for stopping up greater than the aperture, filtering velocity is big, the efficiency of dust filtration height; This again filtering layer is from heavy and light, and smooth surface is transparent, do not absorb water, and no adsorptivity, no chip comes off, the intensity height, good toughness, then intensity is better to make filtering layer as the nucleopore membranes of using Vacuum Coating method to plate layer of metal.Because this filtering layer is easy to clean, and the structure of whole mouth mask makes convenient disassembly, thereby is convenient to reuse.
According to the size of using anti-dust respirator place dust granules, can select the filtering layer of the nucleopore membranes making filter body in different apertures for use, less as required filter membrane aperture, happy for breathing, available two filtering bodies are installed in the left and right sides of mouth mask body; Otherwise, use anti-dust respirator to get final product with a filtering bodies.
The outstanding advantage of this anti-dust respirator is light, and the efficiency of dust filtration height is durable, the filtering bodies convenient disassembly, and filtering layer cleans convenient, and is reusable.
The utility model has following accompanying drawing.
1. the structural representation of anti-dust respirator
Embodiment
As shown in Figure 1, mouth mask body 6 with the polyester material hot forming, with each parts of filtering bodies 7, comprise shell 1, seal 2, supporting network 4 and pad 5, shell 1 has screw thread with mouth mask 6 cooperation places, and spinning compresses, the also available rubber hot forming of seal 2 and pad 5, supporting network 4 is the available metal net also.When filtering bodies 7 is installed, seal with dull and stereotyped seal 2 between shell 1 and the nucleopore membranes filtering layer 3, prevent that dust particle from infiltrating; Then assemble supporting network 4,, assemble pad at last, the filtering bodies 7 that assembles is screwed onto on the opening of mouth mask body 6, compress and get final product with fixing filtering layer 3.
Claims (4)
1. an anti-dust respirator is made up of mouth mask body (6) and filtration members (7), it is characterized in that: filtration members (7) is by shell (1), seal (2), and filtering layer (3), supporting network (4) and pad (5) are formed; Seal (2) is a tabular, and filtering layer (3) adopts has the nucleopore membranes of precision aperture and hole density, and this filter membrane is tiled on the supporting network (4) of porous, uses pad (5) to hold supporting network (4) at last; The inner surface of shell (1) and mouth mask body (6) connection place have screw thread, and mouth mask body (6) spins with filtration members (7) and compresses.
2. by the described anti-dust respirator of claim 1, it is characterized in that the reinforcement nucleopore membranes of the available metal-plated membrane layer of filtering layer (3) of filtration members (7).
3. as claim 1 and 2 described anti-dust respirators, it is characterized in that the material of mouth mask body (6) and filtration members (7) is plastics or rubber, supporting network (4) is the available metal net also.
4. according to the described anti-dust respirator of claim 1～3, it is characterized in that one of center installation or at left and right side a filtration members (7) to be installed respectively on the mouth mask body (6).
