CN2277789Y - Flow type dust-proof gauze mask - Google Patents

Abstract

The utility model relates to a novel circulating type dust-proof gauze mask which uses human breath to drive air to circulate from top to bottom. The novel circulating type dust-proof gauze mask is mainly composed of a skeleton, a double-hole air inlet valve, a single-hole air outlet valve, covering cloth, and a gauze mask belt. When the utility model is used, exhaled air is exhaled out downward from the single-hole air outlet valve, and inhaled air is inhaled from an air chamber of the skeleton through the double-hole air inlet valve, so that users feel cool in breathing. The utility model covers the periphery of face part, and has the similar external shape to a gauze mask. With convenient operation, the utility model can solve the problem that workers who have larger work intensity and work in an environment with much dust need to wear gauze mask.

Description

Novel flow type anti-dust respirator

The novel flow type anti-dust respirator that the utility model utilizes people's breathing that air is circulated from top to bottom, this device mainly is made up of skeleton, diplopore intake valve, single hole air outlet valve, cover, mouth mask belt; The downward single hole air outlet valve of the gas of breathing out during use is breathed out, and sucks air by the diplopore intake valve in the skeleton air chamber when air-breathing, and the people is felt clearly, and this device seals around to face being topped, uses summer and clearly feels more obvious; This device profile is similar to cotton cloth respirator, easy to use, can solve the difficult problem that the bigger operator of labour intensity wears masks when the more environment operation of dust.

The present anti-dust respirator that uses: a kind of is the multilayer cotton cloth respirator, the gauze number of plies of mouth mask is more than 12 layers, the face that cotton cloth respirator is applied ointment or plaster the people is complete topped formula, breathe when operator's labour intensity is big and feel very difficult, cotton cloth respirator is supported by face's bridge of the nose in addition, bridge of the nose both sides and cotton cloth respirator are gapped, and dust sucks from the bridge of the nose two side clearances easily; Another kind is the rubber-type anti-dust respirator, air-breathing is to suck air in the air chamber of two sides disk, expiration is from mouth mask air outlet valve breath, the air inlet of mouth mask and to give vent to anger all be to open and close as valve with sheet rubber, though this mouth mask is better than cotton cloth respirator, its maximum shortcoming is that external form is not attractive in appearance, and volume is bigger, weight is big, use very inconvenient, utilization rate is by adding up with regard to one of not enough percentage in the dust work scope, and secondly the air outlet valve of this anti-dust respirator is easy to generate the dust backflow phenomenon, the dustproof effect of influence.

The utility model purpose provides a kind of novel flow type anti-dust respirator, and external form is similar to cotton cloth respirator, and is easy to use, can solve the difficult problem that the bigger operator of labour intensity wears masks when the more environment operation of dust.

The purpose of this utility model is to realize like this, to understand at first that the operator is more at dust, breathe when labour intensity is big just begin with mouthful and the nostril breathed in phase mutually, at this moment operator's oral area is needing good activity condition, summer weather heat, the operator more needs to reduce the topped area of mouth mask to face as far as possible.According to these characteristics, design a kind of novel flow type anti-dust respirator, this device mainly is made up of skeleton, diplopore intake valve, single hole air outlet valve, cover, mouth mask belt etc.; Skeleton is with people's facial surface modeling design, the skeleton employing is light-duty, soft, nonpoisonous plastic material is made, having diplopore to be installed into air valve above the skeleton uses, the diplopore edge is out-diffusion to several air chambers of all also mutual perforation of skeleton and skeleton one, skeleton below has single hole that air outlet valve is installed to use, and single hole is outwards increased by the edge and expands that do not connect mutually with air chamber together and the security protection circle skeleton one.

Intake valve is installed on the diplopore of skeleton top; air outlet valve is installed on the single hole of skeleton below; the diplopore intake valve; the single hole air outlet valve all uses at present existing garden shape sheet rubber to make valve; the top of skeleton top is equipped with the cavernous body piece and is prevented that dust from sucking from bridge of the nose both sides in bridge of the nose Support Position; the skeleton outside is a cover; cover is the painting cloth of 1-4 layer good permeability; receiving the limit with rubber strip around the cover is fixed on the skeleton; air from the intake valve inspiration filters dust discharge by cover like this; cover also realizes that to air outlet valve protection prevents that dust from refluxing simultaneously; whole anti-dust respirator directly is worn over the people on the face with belt; it is topped that mouth mask surrounding contact people's face carries out the periphery sealing; make operator's oral area that good space is arranged like this, can speak aloud when wearing masks.This device uses when breathing the diplopore intake valve voluntarily and close, the strength that the single hole air outlet valve is breathed out is exhaled out breath, the single hole air outlet valve voluntarily and close when air-breathing, the inspiratory force of personnel selection is inhaled and to be driven air valve suck air in several air chambers of skeleton into, the overall process of breathing makes air circulation from top to bottom in mouth mask, breathing is felt clearly the people, and because of mouth mask is few to the topped area of face, salubrious sense was more obvious when wore summer.This device profile is similar to cotton cloth respirator, easy to use, can solve the difficult problem that the bigger operator of labour intensity wears masks when the more operation of dust.
