Abstract
Description
Technical Field
[0001] This application relates to the field of communication mask technology, and in particular to a communication mask with a built-in sound transmission diaphragm cover and a Bluetooth microphone. Background Technology
[0002] When a fire breaks out, firefighters need to work together to extinguish the fire. During this process, firefighters communicate through Bluetooth microphones installed on their communication masks, thereby completing the collaboration and reducing the time required for firefighting.
[0003] The existing communication mask includes a mask body, a mouth and nose shield installed on the lower side of the mask body, and a Bluetooth microphone magnetically fixed to the outside of the mouth and nose shield. The mouth and nose shield is snapped and fixed to the lower side of the mask body, and a lens is snapped and fixed to the upper side of the mask body. The Bluetooth microphone is located on the upper side of the mouth and nose shield. When firefighters use the communication mask, they put the mask on their heads and then enter the fire scene to carry out firefighting work. At this time, the firefighters communicate through the Bluetooth microphone. The Bluetooth microphone located on the outside of the mouth and nose shield receives and transmits the firefighters' voices, thus enabling firefighters to communicate at the fire scene.
[0004] The aforementioned Bluetooth microphone is located on the outside of the mouth and nose mask. The firefighters' voices are reduced after being blocked by the communication mask, and the sound is low and has a lot of noise after being transmitted through the Bluetooth microphone, which affects the accuracy of the firefighters' communication and needs to be improved. Utility Model Content
[0005] In order to change the installation position of the Bluetooth microphone, reduce the obstruction of firefighters' voice by the communication mask, thereby increasing the sound transmitted by the Bluetooth microphone and reducing noise, and improving the accuracy of firefighters' communication, this application provides a communication mask with a built-in sound transmission diaphragm cover and Bluetooth microphone.
[0006] This application provides a communication mask with a built-in sound-transmitting diaphragm cover and a Bluetooth microphone, employing the following technical solution:
[0007] A communication mask with a built-in sound-transmitting diaphragm cover and a Bluetooth microphone includes a base, a mirror mounted on the outside of the base, a snap-fit groove formed on the lower side of the mirror, and a breathing mask fixed to the inner wall of the snap-fit groove. The inner wall of the snap-fit groove fits against the outer side of the breathing mask. A cover plate is fixed to the inner side of the breathing mask, and a Bluetooth microphone is detachably fixed to the side wall of the cover plate.
[0008] By adopting the above technical solution, when firefighters use communication masks to perform firefighting work, the firefighters install Bluetooth microphones on the side wall of the cover plate. At this time, the Bluetooth microphones are located inside the breathing mask. When firefighters use communication masks to communicate, the Bluetooth microphones are located close to the firefighters' mouths. This setting changes the installation position of the Bluetooth microphones, reduces the obstruction of the communication mask to the firefighters' voices, thereby increasing the sound transmitted by the Bluetooth microphones and reducing noise, thus improving the accuracy of firefighters' communication.
[0009] Optionally, the breathing mask includes a mask body detachably fixed to the inner wall of the snap-fit groove, air inlet valves installed on both sides of the mask body, an air inlet on the outer side of the mask body, and an air outlet on the outer side of the mask body. The air inlet valves connect the inner and outer sides of the mask body, and the air inlet and the air outlet are both connected to the inner side of the mask body. The cover plate is close to the air inlet.
[0010] By adopting the above technical solution, when firefighters use communication masks, they wear the masks on their faces. When firefighters breathe, air enters the inside of the mask and the outside of the breathing mask through the air inlet. Then, the air enters the inside of the breathing mask through the air inlet valve, allowing firefighters to breathe. Exhaled air is discharged through the air outlet. This design enables personnel to breathe stably in the fire scene, improving the safety of firefighters when extinguishing fires.
[0011] Optionally, the breathing mask further includes a sealing ring fixed to the inner wall of the air inlet and a sound-transmitting diaphragm fixed to the inner wall of the sealing ring, with the cover plate fixed to the side of the sound-transmitting diaphragm away from the air inlet.
[0012] By adopting the above technical solution, the sealing ring reduces the possibility of air directly entering the breathing mask through the sound-transmitting diaphragm, providing a stable environment for the air circulation channel inside the communication mask. The sound-transmitting diaphragm improves the accuracy of firefighters' voice transmission, thus facilitating firefighters to communicate in the fire scene using the communication mask.
[0013] Optionally, the sidewall of the cover plate has a receiving cavity, and the sidewall of the Bluetooth microphone can abut against the inner wall of the receiving cavity.
[0014] By adopting the above technical solution, the design of the receiving cavity makes it easier for firefighters to install the Bluetooth microphone on the side wall of the cover plate, thereby improving the efficiency of firefighters in installing communication masks, shortening the preparation time before firefighters enter the fire scene, and thus facilitating firefighters to quickly enter the fire scene to carry out firefighting work; when firefighters remove the Bluetooth microphone from the inner wall of the receiving cavity, the design of the receiving cavity increases the internal volume of the breathing mask, thereby reducing the breathing resistance of firefighters.
[0015] Optionally, the substrate has an air supply valve mounting hole and an exhalation valve mounting hole on the side away from the cover plate. The air supply valve mounting hole is located on the outside of the substrate near the air inlet, and the exhalation valve mounting hole is located on the outside of the substrate near the air outlet.
[0016] By adopting the above technical solution, the installation holes for the air supply valve and the exhalation valve make it easier for firefighters to install the air supply pipe and inhalation pipe of the air respirator onto the communication mask, simplifying the steps for firefighters to install the communication mask and making it easier for firefighters to operate.
[0017] Optionally, a plurality of straps are installed on the sidewall of the substrate, and a head net is fixed to the side of the straps away from the substrate.
[0018] By adopting the above technical solution, the straps and head net ensure that the communication mask is fixed at the firefighter's head when the firefighter is moving violently, reducing the possibility of the communication mask slipping and thus improving the stability of the communication mask during firefighting.
[0019] Optionally, an adjustment buckle is installed on the side of the strap near the base, and the adjustment buckle can adjust the length of the strap.
[0020] By adopting the above technical solution, the adjustable buckle makes it convenient for firefighters of different body types to use the same model of communication mask, so that the same model of communication mask can meet the needs of firefighters of various body types. When the firefighters have finished wearing the communication mask, they can lock the communication mask by adjusting the buckle, which further improves the stability of the communication mask during the use of the firefighters.
[0021] Optionally, a neck strap is fixed to the lower side of the substrate, with both ends of the neck strap fixed to the two sides of the substrate respectively, and the neck strap is located on the side of the substrate closer to the head net.
[0022] By adopting the above technical solution, the neck strap facilitates firefighters in positioning the communication mask. When firefighters remove the communication mask, the mask slides down to a position close to their face due to the pulling force of the neck strap, allowing firefighters to quickly put on the communication mask in emergency situations. This simplifies the process of firefighters putting on the communication mask and makes it easier for them to use.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. When firefighters use communication masks, they attach the Bluetooth microphone to the side wall of the cover plate, then put on the mask. At this time, the Bluetooth microphone is close to the firefighter's mouth. The firefighter can see the fire scene environment through the mirror. When firefighters communicate using the communication mask, their voice is transmitted directly through the Bluetooth microphone. This setting changes the installation position of the Bluetooth microphone, reduces the obstruction of the firefighter's voice by the communication mask, thereby increasing the sound transmitted by the Bluetooth microphone and reducing noise, thus improving the accuracy of firefighters' communication.
[0025] 2. Before firefighters put on the communication mask, they connect the air respirator to the communication mask through the air supply valve mounting hole and the exhalation valve mounting hole. Then, air enters the inside of the mask through the air inlet, and the air inside the mask flows into the inside of the breathing mask through the air inlet valve. At this time, firefighters can breathe. The exhaled exhaust gas flows into the air respirator through the air outlet. This setting facilitates breathing for firefighters and reduces the possibility of firefighters inhaling exhaust gas from the fire scene. Attached Figure Description
