Abstract

The utility model discloses a dust mask which comprises a mask body, wherein an air inlet and an air outlet are arranged on the mask body. The dusk mask is characterized in that the mask body is connected with a filtering device and a mask fixing device and is communicated with the filtering device by the air inlet, and an air-exchange breathing piece is arranged on the air outlet. The filtering device can filter dust in air, and an air-exchange sucking piece and the air-exchange breathing piece can prevent the dust in the air from entering the mask body. When the air-exchange breathing piece and the air outlet break off for unstable connection, the air-exchange breathing piece can be collected by a breathing screen to prevent the air-exchange breathing piece from dropping on the ground, a thin sleeve can increase the tight degree of the mask and the face and can prevent the dust in the air from leaking into the mask from unsealed points, and in addition, the mask is made of light plastic, has light weight and low cost and is suitable for popularization and application.

Description

A kind of anti-dust respirator

Technical field

The utility model relates to breathes dustproof apparatus field, specifically, relates to a kind of anti-dust respirator.

Background technology

In industries such as colliery, cement plant, lime factory, cotton mill, flour mill; the dust of workshop is very many; the workman works in this environment; usually can suck a large amount of dusts; accumulate over a long period; often cause easily multiple disease, for example pulmonary tuberculosis, pneumonia etc., that gives the workman healthyly brings great infringement.At present, the workshop workman wears a cotton mouth mask to prevent to suck dust, and still, this mouth mask is provided with structure and is difficult to hold, and too thin mouth mask does not often have the function that prevents that dust from entering, and too thick mouth mask often influences the workman to be breathed, and causes expiratory dyspnea.This is the deficiencies in the prior art parts.

The utility model content

Main purpose of the present utility model provides a kind of anti-dust respirator, and this mouth mask not only can prevent effectively that the worker from sucking dusts a large amount of in the air, and the worker to wear after sensation comfortable, breathe unimpeded.

The utility model adopts following technical scheme to realize goal of the invention:

A kind of anti-dust respirator comprises the mouth mask body, and described mouth mask body is provided with air inlet and gas outlet, wherein, be connected with filter and mouth mask fixture on the described mouth mask body, described mouth mask body is communicated with by air inlet with filter, and described gas outlet is provided with ventilation and exhales sheet.Described filter can filtered air in dust, ventilation exhales sheet to play breather valve, feels more comfortable when the worker is used, and also can prevent dust inlet port cover body in the air.

Preferably, described filter comprises the shell of hollow, and described enclosure is provided with filter cotton support and filter cotton.

Preferably, described air inlet is provided with ventilation suction sheet.Ventilation is inhaled sheet and is mainly played the breather valve effect, keeps mouth mask internal gas pressure balance, feels more comfortable when the user breathes.

Preferably, be provided with an expiration guard between described mouth mask body and the filter, described expiration guard is positioned on the gas outlet of described mouth mask body.Exhale sheet and gas outlet when being connected not firm coming off when ventilation, the expiration guard can be caught ventilation and exhale sheet, prevents that ventilation from exhaling sheet to drop on the ground.

Preferably, described mouth mask fixture comprises fixing soft band and fixing hard band, and described fixing hard band is provided with buckle, and the mouth mask fixture is fixed in mouth mask in people's face.

Preferably, the outward flange of described mouth mask body is provided with one deck and has flexible thin cover.Thin cover can increase the closed intensity of mouth mask and people's face, prevent dust in air never driving fit place be leaked in the mouth mask.

Compared with prior art, advantage of the present utility model and good effect are: filter of the present utility model can filtered air in dust, sheet is inhaled in ventilation and ventilation exhales sheet to have the effect of breather valve, keep mouth mask internal gas pressure balance, make the breather feel comfortable, also can prevent dust inlet port cover body in the air.Exhale sheet and gas outlet when being connected not firm coming off when ventilation, the expiration guard can be caught ventilation and exhale sheet, prevents that ventilation from exhaling sheet to drop on the ground, and thin cover can increase the closed intensity of mouth mask and people's face, prevent dust in air never driving fit place be leaked in the mouth mask.In addition, mouth mask adopts light plastic, very light in weight, and cheap, suitable applying.
