Abstract

The utility model provides a protective face mask, which belongs to the technical field of occupational disease prevention, and comprises a mouth mask. The upper end of the mouth mask is connected to an eye mask, and the left end and the right end of the mouth mask are respectively connected to a connecting band. The connecting band is provided with an earmuff, and the end part of the connecting band is provided with a hasp. The protective face mask is characterized in that the earmuff and the connecting band are in a hinged joint; the connecting band is provided with a hole cooperating with the earmuff; the earmuff can rotate around a hinge, and thereby the hole can be buckled or opened; the eye mask is a transparent anti-ultraviolet plastic structure. The protective face mask is advantageous in that dust and powder can be prevented from entering into oral cavities and noses, and noise can be prevented from entering into ears, and ultraviolet rays can be prevented from irradiating eyes in work environment; occupational diseases like pneumoconiosis, noise deafness, electric ophthalmia can be prevented; language communication of workers during work cannot be affected; language communication of workers during work cannot be affected; use is convenient, and factors capable of preventing occupational diseases can be well protected, and manufacturing and using cost is low.

Description

A kind of protective face mask

Technical field

The utility model relates to a kind of technical field of occupational disease protection, especially relates to the mask of a kind of dust, noise, ultraviolet operation.

Background technology

There are at present many industries, labourer's operation under dust atmosphere of having to, and simultaneously contact noise and the ultraviolet certain proportion that also occupies in the industry of dust work, excessive dust exposure, noise and ultraviolet ray can cause the occupational diseases such as pneumoconiosis, noise-induced deafness and electric ophthalmia, and pneumoconiosis and noise-induced deafness patient are difficult to cure, often to patient, causing lifelong disability, is also white elephant to family and society.In order to prevent that labourer from sucking excessive dust while working under dust, noise, UV environment, contact excessive noise and ultraviolet ray, ordinary circumstance labourer to be adopted and wears anti-dust respirator, earmuff, safety goggles and be used for preventing the injury of occupational to human body, owing to wearing three kinds of protective articles simultaneously, not only wear trouble, very inconvenient during work, but actual effect is also undesirable, and labourer also has groups of people and suffers from occupational disease.Chinese patent Granted publication CN202680571U, on January 23 2013 Granted publication date, name is called the utility model patent of " a kind of dust mask ", discloses a kind of dust mask.It comprises mouth mask, eyeshade, connecting band, earmuff, hasp, across band, buckle.Wherein the upper end of mouth mask connects eyeshade, eyeshade is transparent plastic structure, the two ends, left and right of mouth mask are connected with respectively connecting band, the top that the end of connecting band is provided with hasp earmuff is connected with across band, across with two, one end across band is connected with two connecting bands of mouth mask left and right respectively, this utility model has played general protection operator oral cavity, nose, eye, the effect of ear, protected labourer at dust, noise, under UV environment, the infringement of occupational is avoided in operation, easy to use, labourer takes action unaffected, but this utility model also has the place of its deficiency, that operator under the large environment of noise with on this dust mask protected communication and the communication that has also affected itself and other staff in operator's ear.

Utility model content

In order to solve the problems referred to above in prior art; the present invention is at above-mentioned Chinese patent Granted publication CN202680571U; name is called on the basis of utility model of " a kind of dust mask " to be improved; in order to accomplish not only to protect ear but also can exchange with other people when needed, the utility model adopts following technical scheme.

The technical solution of the utility model is: a kind of protective face mask, comprise mouth mask, and the upper end of mouth mask is connected with eyeshade, and the two ends, left and right of mouth mask are connected with respectively connecting band, and connecting band is provided with earmuff, and the end of connecting band is provided with hasp.

It is characterized in that earmuff and connecting band are connected through the hinge, on connecting band, have a hole of matching with earmuff, thereby earmuff can rotate and cut out or open described hole around hinge.The operating personnel who conveniently wears this face shield when the effect in hole is to need hears external sound, when operating personnel need to carry out communication with other staff, opening earmuff just can exchange, when operating personnel does not need to carry out communication with other staff, just can buckle earmuff, prevent that noise from entering ear.

As preferably, around earmuff, there are a passive sclerosphere, the sclerosphere of earmuff to have one deck bafta parcel, the surrounding in hole has a passive sclerosphere equally, and this sclerosphere can engage with the sclerosphere of earmuff.

As preferably, there is not sound insulation of one deck the bottom in hole but can stops the filter screen of dust.

As preferably, mouth mask is some layers of NACF silk net and bafta overlaying structure; Permeability is good, can not only filter out dust, also can prevent the invasion of harmful substance.

As preferably, eyeshade is transparent antiultraviolet plastic production; Alleviate face shield weight, eyeshade convenient for cleaning.

As preferably, earmuff is some layers of bafta overlaying structure, and earmuff is located on connecting band; Both protect ear not encroached on by dust, and can isolate again the noise of operating environment.

As preferably, the top of earmuff is connected with across band; Guarantee that face shield wears firmly.

As preferably, on earmuff lateral wall, there is a projection that conveniently fastens or open earmuff.

Compared with prior art, the beneficial effects of the utility model are: under the environment of dust work, prevent that dust from entering human body from oral cavity and nose, effectively protected labourer's health, avoided the generation of pneumoconiosis; Because containing earmuff and eyeshade in device, simultaneous noise under dust work environment and ultraviolet ray are also had to good protective action to the injury of human body simultaneously, avoided the generation of the occupational diseases such as noise-induced deafness and electric ophthalmia.This device does not affect operator and carries out when needed communication, and easy to use, good to occupational protection effect, manufacturing cost and use cost is low.
