[0024] The following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for the purpose of illustrating and explaining the present invention, and are not used to limit the present invention.

[0025] In the present invention, unless otherwise stated, the orientation terms such as "inside, outside" included in the terms only represent the orientation of the terms in the normal use state, or the common names understood by those skilled in the art, and should not be regarded as a limitation to the terms.

[0026] See Figures 1 to 4 , the present invention provides a built - in sound - collecting and communication device for a firefighting mask. The built - in sound - collecting and communication device for the firefighting mask includes a sound - pickup device 3 and a rotating microphone 5. The rotating microphone 5 is arranged to be driven by an electric motor 6 and rotate the sound - pickup direction through a rotating shaft 4. A microphone mask base 9 is provided on the firefighting mask 12. The sound - pickup device 3 is detachably mounted on the microphone mask base 9. Among them, a volume sensor is provided in the sound - pickup device 3. The volume sensor is connected to the electric motor 6 through a processor and is used to drive the electric motor 6 to adjust the rotating microphone 5 to the best angle according to the sound - volume source. A gyroscope sensor is also provided in the sound - pickup device 3. The gyroscope sensor is arranged to control the sound - pickup device 3 to turn on, go into sleep or turn off according to the change of its own motion coordinates.

[0027] Through the above technical solution, by arranging the sound - pickup device 3 inside the firefighting mask 12, the influence of external noise on the sound - collecting effect can be reduced in a complex rescue environment, greatly enhancing the sound - collecting effect of the sound - pickup device 3. A microphone mask base 9 is provided on the firefighting mask 12, and the sound - pickup device 3 is detachably mounted on the microphone mask base 9, which can solve the problem that different types of firefighting masks 12 need to be equipped with different models of sound pickups, improving the versatility of the sound - pickup device 3. Moreover, a volume sensor is provided in the sound - pickup device 3. The volume sensor is connected to the electric motor 6 through a processor and can drive the electric motor 6 to adjust the rotating microphone 5 to the best sound - collecting angle according to the sound - volume source. At the same time, a gyroscope sensor is also provided in the sound - pickup device 3. When the device is picked up, the coordinates of the gyroscope sensor change, and the sound - pickup device 3 automatically starts to work. After being in a stationary state for a certain period of time, the sound - pickup device 3 automatically stops working, that is, it enters the sleep state, which not only reduces the power consumption but also eliminates the need for firefighters to manually turn on and off frequently, making it more convenient for firefighters to use and thus improving the rescue efficiency.

[0028] In order to quickly and conveniently install the sound pickup device 3 onto the microphone mask base 9 during use or easily remove the sound pickup device 3 from the microphone mask base 9 after use, in one implementation, preferably, a second magnet 8 is provided on the microphone mask base 9, and a first magnet 7 capable of cooperating with the second magnet 8 is provided inside the sound pickup device 3. In this way, the sound pickup device 3 can be quickly installed and removed from the microphone mask base 9 through the mutual attraction between the first magnet 7 and the second magnet 8.

[0029] Furthermore, when the first magnet 7 and the second magnet 8 are frequently mutually attracted for a long time, due to collisions, it is easy to cause damage or loosen and fall off from the installation location, losing the original quick and convenient installation function. To avoid the above situation, preferably, the first magnet 7 and the sound pickup device 3 are integrally formed by injection molding. Similarly, the second magnet 8 and the microphone mask base 9 can also be integrally formed by injection molding. Using this integral structure eliminates the worry about the detachment of the first magnet 7 and the second magnet 8, greatly extending the service life.

[0030] Similarly, in order to quickly and conveniently install the sound pickup device 3 onto the microphone mask base 9 during use or easily remove the sound pickup device 3 from the microphone mask base 9 after use, in another implementation, a fiber surface of a hook-and-loop fastener is provided on the microphone mask base 9, and a bristled surface of a hook-and-loop fastener is provided on the surface of the sound pickup device 3. In this way, the sound pickup device 3 can be easily installed or removed through the mutual cooperation between the bristled surface and the fiber surface.

[0031] The connection and fixation method between the above-mentioned microphone mask base 9 and the fire mask 12 can be any common quick connection method in the art. However, considering the convenience of operation, easy access to materials, and control of production and use costs, preferably, the microphone mask base 9 is fixed to the fire mask 12 through a double-sided adhesive layer 10. Fixing with the double-sided adhesive layer 10 not only makes the structure stable after connection but also reduces the overall weight of the fire mask, making it more convenient and labor-saving for firefighters to wear.

[0032] In addition, when firefighters use the built-in sound pickup and communication device of the fire mask, to facilitate the operation of the sound pickup device 3, preferably, a Bluetooth pairing button 1 is provided on the sound pickup device 3, and the Bluetooth pairing button 1 is used to turn on the Bluetooth module set inside the sound pickup device 3 for wireless connection and pairing with external devices.

[0033] In addition, in order to be able to use the built-in voice pickup and communication device of the fire protection face mask for a long time, frequently, and multiple times, it is preferred that a charging port 2 is provided on the voice pickup device 3 for connecting a power source to charge the built-in battery of the voice pickup device 3. In this way, the battery can be charged after use, ensuring sufficient power for the next use. At the same time, when a certain battery has been used for a long time and is approaching its service life, the built-in battery can also be replaced so that the built-in voice pickup and communication device of the fire protection face mask can continue to be used and operated.

[0034] The preferred embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solutions of the present invention, including any suitable combination of individual specific technical features. To avoid unnecessary repetition, the present invention will not separately describe various possible combination methods. However, these simple modifications and combinations should also be regarded as the content disclosed by the present invention and fall within the protection scope of the present invention.
