Abstract

The utility model relates to a transmitter spit guard for a breathing mask. The spit guard comprises a fixed seat, wherein a buckle is arranged on the edge of the fixed seat, and matched with an assembly groove formed on a transmitter assembly seat; and a groove for spit guard mesh is formed on the fixed seat. The fixed seat is assembled on the transmitter of the breathing mask, the spit guard mesh is arranged on the fixed seat, so that breath and breathing moisture generated when a user talks in a close range can be effectively blocked, and voice wave is less attenuated when being transmitted to the transmitter through the spit guard, so that interference of breath sound and vibration sound can be greatly weakened, the breathing moisture can be effectively isolated, and the calling quality and reliability are improved. The transmitter spit guard has a simple structure, and the existing oxygen-supply protective performance is maintained.

Description

The transmitter spray guard of breathing mask

Technical field

The utility model relates to a kind of breathing mask, especially a kind of transmitter spray guard of breathing mask.

Background technology

In fields such as aviation and fire-fightings, breathing mask is mainly users such as pilot and fireman and when work, filters oxygen supply, is user's crucial protecting equipment.Transmitter is installed on the breathing mask supplies user's communication to use, yet breathing mask is mainly reflected on the barrier propterty that improves oxygen supply at present, calling quality receives the influence of respiratory air flow bigger because of the restriction of cavity space.In actual use; The user air-flow that the distance because of transmitter and mouth too closely causes speaking occurs through regular meeting and is sprayed onto the phenomenon on the transmitter when wearing breathing mask, especially speaks the user that word speed is too fast, voice is greatly and in the detonation distorsion; Can produce the interference of tangible air-flow sound and Rack; And breathe the quality that steam can influence transmitter, threaten the life-span of receiver, these all can comparatively seriously influence user's speech quality and reliability generation.

The utility model content

The purpose of the utility model is to provide a kind of can eliminate the interference of air-flow sound and Rack, the transmitter spray guard that the breathing mask of steam, raising speech quality and reliability is breathed in isolation.

For realizing above-mentioned purpose; The utility model has adopted following technical scheme: a kind of transmitter spray guard of breathing mask, comprise holder, and the edge of holder is provided with buckle; The mounting groove of offering on buckle and the transmitter mount pad matches, and offers the groove that is used to install the blowout prevention net on the holder.

Can know by technique scheme; Holder in the utility model is installed on the transmitter of breathing mask; The blowout prevention net is installed on the holder, make the closely just effective deadening of ability quilt of the air-flow of generation and breathing steam in a minute of user, and speech sound waves is very little through the decay that spray guard propagates into transmitter; So just slacken the interference of air-flow sound and Rack greatly and effectively isolated breathing steam, improved speech quality and reliability.The utility model simple in structure kept original oxygen supply barrier propterty.

Description of drawings

Fig. 1,2 all is structural representations of the utility model;

The structural representation that Fig. 3 matches with transmitter and mount pad thereof for the utility model.

The specific embodiment

A kind of transmitter spray guard of breathing mask; Comprise holder 1; The edge of holder 1 is provided with buckle 2, and the mounting groove of offering on the mount pad 10 of buckle 2 and transmitter 9 11 matches, and transmitter 9 is fixedly mounted on the breathing mask; Offer the groove that is used to install the blowout prevention net on the holder 1, like Fig. 1,2, shown in 3.

Like Fig. 1, shown in 2, described holder 1 is the circular of hollow, and the edge of holder 1 is two buckles 2 of separation symmetrically and evenly.Its central axial direction symmetry of described holder 1 upper edge is offered first and second groove 3,4; First and second groove 3, gapped between 4; First and second trim ring 5,6 lays respectively in first and second groove 3,4; The first blowout prevention net 7 is between first trim ring 5 and first groove 3, and the second blowout prevention net 8 is between second trim ring 6 and second groove 4.Described first and second trim ring 5,6 all becomes circular, and the shape of first and second trim ring 5,6 matches with the shape of first and second groove 3,4 respectively, and the wire side of described first and second blowout prevention net 7,8 is circular.First trim ring 5 is pressed in the first blowout prevention net 7 in first groove 3, and second trim ring 6 is pressed in the second blowout prevention net 8 in second groove 4, and is this simple in structure, is convenient to dismounting.

When the user uses; The sound that the user sends successively is passed to transmitter through first and second blowout prevention net 7,8 again; The air-flow of following in the voice is effectively deadened by first and second blowout prevention net 7,8; And the sound wave energy that the user speaks is effectively picked up by transmitter 9 through spray guard, has so just slackened the interference of air-flow sound and Rack and has effectively isolated breathing steam, has improved calling quality.
