Abstract
A gas mask facilitating conversation comprises a mask body; the mask body is provided with a breathing valve and an eye window; a conversation diaphragm assembly is arranged on the breathing valve and comprises an outer shell; the outer shell is composed of an upper buckle and a lower clamp; the upper buckle is of an arch structure; a clamping groove is formed in the edge of the lower clamp; the upper buckle is buckled with the lower clamp through the clamping groove; and sound diaphragms are arranged on the lower clamp and the upper buckle. By the adoption of the structure, on the basis of well meeting the demand of communication between mask wearers, the sound transmission loss is effectively reduced when sound passes through the mask.
Description
Technical field
The present invention relates to a kind of canister respirator, be specifically related to a kind of canister respirator facilitating wearer transaudient.
Background technology
Canister respirator, as personal protection equipment, provides effectively protection for the respiratory apparatus to personnel, eyes and skin of face.Canister respirator is mainly made up of parts such as filter element, cover body, eye window, expiration communicator and headbands, they each have their own responsibilities, can tacit agreement coordinate again simultaneously.
Wherein the cover body of canister respirator is that each parts are constituted holistic critical piece, people carry out augmentative communication typically requiring electronic equipment when wearing a gas mask, the cost of manufacture of mask can be greatly increased after so electronic equipment is set on canister respirator, strengthen the weight of mask self, have a strong impact on the portability of mask.
Summary of the invention
The technical problem to be solved is for above-mentioned the deficiencies in the prior art, and the one provided is easy to call canister respirator, and it can solve canister respirator not to be well positioned to meet between wearer transaudient to link up the problem needed.
The purpose of invention is achieved in that
One is easy to call canister respirator, it includes face shield, face shield is provided with respiratory valve and eye window, described respiratory valve is provided with call membrane module, and call membrane module includes shell, and shell is made up of upper fastener and lower fastener, upper fastener is domes, the edge of lower fastener is provided with draw-in groove, and upper fastener is engaged with lower fastener by draw-in groove, and lower fastener and upper fastener are provided with sound film.
Described upper fastener and lower fastener are provided with trim ring in junction.
Described trim ring is plastics trim ring, and sound film is PEN sound film, and shell is aluminium shell.
The present invention achieves following technique effect:
Adopting said structure, the present invention can wear on the basis linking up needs between personnel well meeting mask, effectively reduces sound in the sound transmission loss through mask.
Adopting sound film is PEN sound film, and shell is aluminium shell, and trim ring is the structure of plastics trim ring, can well reduce the sound transmission loss of call membrane module, and improve the resistance to ag(e)ing of call membrane module.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is the structural representation of the present invention；
Fig. 2 converses the structural representation of membrane module in Fig. 1.
Detailed description of the invention
One is easy to call canister respirator as shown in Figure 1, and it includes face shield 5, and face shield 5 is provided with respiratory valve 6 and eye window 7, and described respiratory valve 6 is provided with call membrane module 1,
As in figure 2 it is shown, call membrane module 1 includes shell, shell is made up of upper fastener 101 and lower fastener 102, upper fastener 101 is domes, the edge of lower fastener 102 is provided with draw-in groove 4, and upper fastener 101 is engaged with lower fastener 102 by draw-in groove 4, and lower fastener 102 and upper fastener 101 are provided with sound film.
Described upper fastener 101 and lower fastener 102 are provided with trim ring 2 in junction.
Described trim ring is plastics trim ring, and sound film is PEN sound film, and shell is aluminium shell.
Adopting said structure, the present invention can wear on the basis linking up needs between personnel well meeting mask, effectively reduces sound in the sound transmission loss through mask.
Being PEN sound film by sound film, shell is aluminium shell, and trim ring is the structure of plastics trim ring, can well reduce the sound transmission loss of call membrane module, and improve the resistance to ag(e)ing of call membrane module.
