Abstract

Provided is a light communication face mask. According to the communication face mask, a loudspeaker, a cell box, a listening-talking conversion button, an interphone port, a switch and an earphone are integrated into a whole and placed on the left or on the right of the face mask, the earphone is placed on an oronasal cover, the loudspeaker of a microphone faces towards the outer side of the face mask, the earphone faces the internal of the face mask on the back of the microphone, the listening-talking conversion button is arranged above the microphone, the switch is arranged on the back lower portion of the microphone, and the interphone port is arranged below the microphone and between the switch and the cell box. According to the communication face mask, the structure is simple, cost is reduced, the weight and rotational inertia are reduced, and leak tightness between a face mask seal ring and the face of a human body is guaranteed.

Description

The communication face shield

Technical field

The utility model relates to a kind of communication device, especially has the face shield that enlarges the face mask wearer spoken sounds and realize clear conversation by an intercom and a distant place.

Background technology

At present, known communication face shield configuration by loudspeaker, battery case, pay attention to the class switching button, switch, intercom interface, earphone, microphone and face shield and form.The lower right that loudspeaker is placed on mask interface is connected with mask interface, battery case, pay attention to the class switching button and be connected with mask interface with the lower left of intercom interface in mask interface, earphone extends to by people's the ear by a flexible pipe, and microphone is fixed on the soniferous membrane edge.But, these communication face shields exist weight too heavy, be worn over obvious tenderness sense is arranged on the head, distribution of weight is far away apart from people's face, the rotary inertia that produces when human body head rotates is big, can have a strong impact on the sealing of mask seal circle and human face, cause gas leakage, reduce the barrier propterty of face shield and the service time of respirator.

Summary of the invention

Too many in order to overcome existing communication face shield increase face shield weight, be worn over obvious tenderness sense is arranged on the head, distribution of weight is far away apart from people's face, the rotary inertia that produces when human body head rotates is big, can have a strong impact on the sealing of mask seal circle and human face, cause gas leakage, the deficiency of the barrier propterty of reduction face shield and the service time of respirator, the utility model provides a kind of communication face shield, this communication face shield is not only in light weight, and distribution of weight is little apart from face's distance of people, can reduce rotary inertia.

The technical scheme that its technical problem that solves the utility model adopts is: with loudspeaker, battery case, pay attention to the class switching button, switch, the intercom interface, earphone is integrated in the housing, form loudspeaker, loudspeaker is placed on the face shield left side or the right, two metal connecting sheet one ends are connected with face shield by the clamp tightening bolt between clamp on the face shield and the following clamp, the other end is connected with micropkonic flange D by two screws, flange D has the baffle plate E that covers connecting portion outward, microphone is contained on the oronasal mask, the microphone cord down is contained in down between clamp and the mask seal circle, clamp is to the oronasal mask below under the edge, pass the mask seal circle, enter in the face shield from the face-port inward flange and to be connected with microphone, loudspeaker on the loudspeaker is towards the face shield outside, earphone at loudspeaker behind in face shield, pay attention to the class switching button above loudspeaker, switch is in the loudspeaker back lower place, and the intercom interface is between loudspeaker lower switch and battery case.When the wearer talks, microphone on the oronasal mask transmits signals to loudspeaker, amplifying processing through signal has loudspeaker to spread out of, realize sound amplification function, when connecting intercom, the wearer presses and pays attention to the class switching button, and spoken sounds reaches the intercom in a distant place through intercom, decontrols button and can hear the sound that distant place intercom transmits in earphone.

The beneficial effects of the utility model are, with loudspeaker, battery case, pay attention to the class switching button, the intercom interface, switch, earphone becomes one, be placed on the face shield left side or the right, the earphone dress is placed on the oronasal mask, loudspeaker on the loudspeaker is towards the face shield outside, earphone at loudspeaker behind in face shield, pay attention to the class switching button above loudspeaker, switch is in the loudspeaker back lower place, the intercom interface is between loudspeaker lower switch and battery case, and is simple in structure, reduces cost, alleviate weight and rotary inertia, guaranteed the sealing of mask seal circle and human face.
