Abstract
The utility model relates to an electromagnetic protective gauze mask with a filter cleaner working in the environment with harmful substances, such as smoke and dust, poisonous dust, etc. The utility model is characterized in that a baffle plate with through holes is covered on the active layer facing the air intake direction in the filter cleaner, a layer of particle-shaped soft magnetic material is increased at one side of the baffle deviating from an activated carbon layer, and a magnetic baffle, etc. with through holes are arranged for covering the soft magnetic material layer. Coming close to the sucking holes of the filter cleaner, the harmful substance particles are rejected or absorbed by the electrostatic generated by the electrostatic substance, and the magnetic harmful substance particles are absorbed by the soft magnetic material layer, which prevents the harmful substances from inhaling into the human body.
Description
The utility model relates to and a kind ofly prevents harmful substance through ports such as flue dust, malicious dirt, nasal respiration and electromagnetic type protective mask in the suction body, be by with people's facial close-fitting cavity arch face shield with at the exhalation check valve of its dome portions device, and form at the suction check valve and the active carbon cleaner with matching of the configuration of face shield bottom.Belong to the mouth mask manufacturing technology in the articles for labour protection.
In environment, work with flue dust, malicious dirt, in order to prevent in these harmful substance suction bodies, generally be in breathing tube, to be placed with active carbon to do protection as the gas mask of cleaner, but this device only has the adsorption filtration effect to poison gas, and to too small flue dust, malicious dirt particle can't filtering.
The purpose of this utility model is exactly at the weak point of can't the filtering too small flue dust of the gas mask in above-mentioned, malicious dirt particle and provide a kind of and prevent that harmful substance through port, nasal respiration from entering the electromagnetic type protective mask in the body.
Task of the present utility model realizes by following technical characterictic: the facial close-fitting cavity arch face shield with the people, at its dome portions device exhalation check valve, the face shield bottom disposes a unidirectional inlet valve and the cleaner that active carbon layer is housed with matching, in cleaner on the active carbon layer of airintake direction, add the dividing plate that lid layer has through hole, laminated at dividing plate away from active charcoal, dose one deck graininess soft magnetic materials, and the magnetic dividing plate that has through hole that covers layer of soft magnetic material is set, side at the magnetic dividing plate that deviates from layer of soft magnetic material, load one deck can produce static through friction material, then at electrostatic substance outer surface upper cover one deck silk, a sheet that electrifies that can rotate with the buckle closure axis also is set having being fastened on of through hole in the buckle closure on the cleaner, has on the sheet that electrifies and the corresponding through hole of buckle closure through hole.
Owing to be suspended in the harmful substances in air particle, some self has static or magnetic, some is by having static or magnetic with windage, therefore, when harmful substance particle during near the inlet hole of cleaner, by Coulomb repulsion or the absorption that electrostatic substance produces, have the promptly adsorbed of magnetic, thereby prevented in the harmful substance suction body by layer of soft magnetic material.
Accompanying drawing 1 is the structural representation of the utility model most preferred embodiment.
Accompanying drawing 2 is structural representations of the cleaner inside in the utility model.
Be further described below in conjunction with the technology contents of accompanying drawing present embodiment.
Face with the people closely cooperates the cavity face shield (2) of elastic cord (1) is arranged by two side-lines that rubber is made and the edge inwardly folds into, at its dome portions device exhalation check valve (3), face shield (2) bottom configuration one suck check valve (4) and match with it the round barrel shape cleaner (6) that gauze ［ 17 ］ and its thickness are 20mm active carbon (5) layer is housed, in cleaner (6) inside face on active carbon (5) layer of airintake direction, add a cover a dividing plate (8) that is covered with through hole (7), on the dividing plate (8) of away from active charcoal (5) layer, dosing a layer thickness is graininess soft magnetic materials (9) layer of 10mm, and on soft magnetic materials (9) layer, a magnetic is set every analysing (10), be covered with through hole (7) on it and be embedded with the magnet piece that magnetic field intensity is 10000 Gausses (11) in magnetic dividing plate (10) one sides that deviate from soft magnetic materials (9) layer, load a layer thickness and be 20mm and entangle the electrostatic substance (12) that dimension is formed by rosin particle and wool or chemistry, then at electrostatic substance outer surface upper cover one deck silk (13), the disc sheet (15) that electrifies is set in the buckle closure (14) on cleaner (6), the sheet (15) that electrifies can be covered with on it and the corresponding through hole of buckle closure (14) through hole (7) (7) with buckle closure (14) axis (16) rotation.
In the present embodiment, through hole (7) diameter is 3mm, and block board thickness is 2mm, and the sheet that electrifies (15) thickness is 2mm, and axis (16) diameter is 5mm, and magnetic dividing plate (10) thickness is 2mm.
Claims (3)
1, a kind of by with people's facial close-fitting cavity arch face shield with at the exhalation check valve of its dome portions device, and the electromagnetic type protective mask of being formed at the suction people check valve and the active carbon cleaner with matching of face shield bottom configuration, it is characterized in that in cleaner on the active layer of airintake direction, add the dividing plate that lid layer has through hole, laminated at dividing plate away from active charcoal, dose one deck loose shape soft magnetic materials, and the magnetic dividing plate that has through hole that covers layer of soft magnetic material is set, side at the magnetic dividing plate that deviates from layer of soft magnetic material, load one deck can produce static through friction material, then at electrostatic substance outer surface upper cover one deck silk, a sheet that electrifies that can rotate with the buckle closure axis also is set having being fastened on of through hole in the buckle closure on the cleaner, has on the sheet that electrifies and the corresponding through hole of buckle closure through hole.
2, electromagnetic type protective mask according to claim 1 is characterized in that: electrostatic substance is mixed by rosin particle and wool or chemical fibre, and its thickness is 20mm.
3, electromagnetic type protective mask according to claim 1 is characterized in that the magnetic dividing plate is embedded with the magnet piece that magnetic field intensity is 10000 Gausses.
