Description

Technical Field

[0001] This disclosure relates to the field of breathing mask communication devices, and in particular to a communication device with air bypass function. Background Technology

[0002] When firefighters wear breathing masks to carry out firefighting operations, their mouths are sealed by the masks, making it impossible for them to effectively transmit their voices, thus hindering communication.

[0003] In addition, when firefighters are wearing masks and approaching the fire line, moving to a new position, or resting in a safe area, the smoke content in the ambient air is sparse, so they need to remove their breathing masks to breathe fresh air. When the fire suddenly intensifies and smoke comes in, they need to put their breathing masks back on. The operation is quite cumbersome and makes it impossible to provide respiratory protection immediately.

[0004] Currently, there is no communication device with a quick switching function for ambient air bypass, which, in addition to the communication function, can also be quickly turned off and prevented from being accidentally turned on.

[0005] Therefore, a communication device with rapid switching function for ambient air bypass is urgently needed for development. Utility Model Content

[0070] The purpose of this embodiment is to provide a communication device with a fast switching function for ambient air bypass, and the specific embodiment is as follows.

[0071] Example 1:

[0072] This disclosure provides an embodiment:

[0073] like Figure 1A communication device with air bypass function includes: a base 1, a sealing ring 2, a communication component, an elastic element 6, and a rotation limiting component; wherein, a through hole 1A for ventilation is provided on the side wall of the base 1; the sealing ring 2 is disposed between the base 1 and the communication component; the communication component is movably disposed within the base 1 for communicating with the outside; the elastic element 6, such as a spring, is disposed between the communication component and the base 1; to prevent harmful gases, such as smoke, from entering the base 1, the communication component seals the through hole 1A after compressing the elastic element 3; and after compressing the elastic element 3, a rotation limiting component is used to limit the movement to prevent rebound; the rotation limiting component is disposed on the outside of the base 1 to limit the communication component, so that when the rotation limiting component rotates, the elastic element 6 pushes the communication component out of the base 1, thereby connecting the through hole 1A with the outside and realizing the air bypass function.

[0074] In this embodiment, in addition to serving as a fixed intercom component, the base 1 also needs to provide air bypass. Therefore, preferably, the base 1 includes: a base body 101 and a base extension 102; wherein, the base extension 102 is disposed on the side of the base body 101 near the intercom component; the base extension 102 is provided with an anti-detachment protrusion 102A inside to prevent the intercom component from detaching from the base extension 102; and a through hole 1A is disposed on the base extension 102.

[0075] Specifically, such as Figure 2 and 3 To improve operability, the rotation limiting assembly includes: two connectors 10, a torsion spring 3, an elastic pin 4, and a press buckle 5; wherein, the two connectors 10 are symmetrically arranged on the base 1; the elastic pin 4 is disposed on the connector 10; the torsion spring 3 is disposed on the elastic pin 4; the press buckle 5 is disposed on the connector 10 after being connected to the elastic pin 4, and the press buckle 5 can rotate around the elastic pin 4; one end of the torsion spring 3 contacts the connector 10, and the other end contacts the press buckle 5; the end of the press buckle 5 is provided with a limiting structure for limiting the communication component and preventing the elastic element 3 from rebounding.

[0076] Specifically, in this embodiment, such as Figure 4 The press buckle 5 includes: a press buckle body 501, a connecting protrusion 502, and a limiting protrusion 503; wherein, the connecting protrusion 502 is disposed on the press buckle body 501; the limiting protrusion 503 is disposed at the end of the press buckle body 501 to form the limiting structure; the connecting protrusion 502 is provided with a shaft hole 502A for disposing of the elastic pin 4.

[0077] During use, if the elastic element 3 is compressed, the communication component seals the through hole 1A and is fixed by the limiting protrusion 503 at the end of the pressing buckle body 501, preventing the elastic element 3 from rebounding and ensuring that the communication component always seals the through hole 1A. This prevents external smoke or other harmful gases from entering the base 1 through the through hole 1A and thus into the fire mask, causing harm to the human body. When air bypass is required, the pressing buckle body 501 needs to be pressed manually, causing it to apply pressure to the torsion spring 3, resulting in deformation. This causes the pressing buckle body 501 to rotate around the elastic pin 4, displacing the limiting protrusion 503 on the pressing buckle body 501, and ultimately disengaging it from the communication component. The elastic element 6 then resets, the communication component moves away from the through hole 1A, and the base 1 can breathe with the outside, achieving the air bypass function.

[0078] The call component described in this embodiment needs to meet the amplification requirements, such as... Figure 1 Specifically, it includes: a telephone cover 7, a telephone housing 8, and a telephone diaphragm 9; wherein, the telephone housing 8 is connected to the base 1; the telephone diaphragm 9 is disposed inside the telephone housing 8 for external amplification; the telephone cover 7 is disposed inside the telephone housing 8 for fixing the telephone diaphragm 9; to facilitate fixing, the elastic member 6 is located between the telephone housing 8 and the telephone cover 7, for allowing the telephone housing 8 to detach from the base 1 so that the through hole 1A communicates with the outside.

[0079] Specifically, such as Figure 5 The communicator cover 7 includes: a cover body 701 and a cover extension 702; wherein, the cover body 701 is disposed on the side of the communicator membrane 9 away from the communicator housing 8; the cover extension 702 is disposed away from the communicator membrane 9, and is used to form a space for placing the elastic element 6 between the cover extension 702 and the communicator housing 8; both the cover body 701 and the communicator housing 8 are provided with annular protrusions, and when installation is required, the two annular protrusions are fastened together to form a detachable structure, such as... Figure 6 At point S in the diagram.

[0080] To facilitate compatibility with the intercom cover 7, such as Figure 7 The communicator housing 8 includes: a communicator housing body 801, a first extension 802, and a second extension 803; wherein, the communicator housing body 801 is disposed on the side of the communicator diaphragm 9 facing outward; the first extension 802 is disposed towards the communicator diaphragm 9 for fixing the communicator diaphragm 9; the second extension 803 is movably disposed within the base 1; as shown Figure 8 and 9The second extension 803 is provided with a fixing protrusion 803A on the side facing the communicator cover 7, for detachable connection with the mating part 701A at the end of the communicator cover body 701; the second extension 803 is provided with an anti-detachment structure 803B on the side facing the base 1, for preventing the communicator shell 8 from detaching from the base 1.

[0081] To improve call quality, both the communicator housing body 801 in the communicator housing 8 and the communicator cover body 701 in the communicator cover 7 are provided with evenly distributed holes for sound transmission. For ease of connection, the outer side of the base 1 is provided with a connecting component 1B, such as a slot, that can be detachably connected to the outer interface cover.

[0082] The communication device with air bypass function described in this embodiment has a simple structure. In actual production, the communication diaphragm 9 can be made of fire-retardant thin film elastic material, which provides good sound transmission and effectively prevents damage to the device caused by high temperatures and flying sparks. Meanwhile, the base 1, communication cover 7, and communication shell 8 can all be made of flame-retardant materials to improve fire resistance and ensure safe use. Furthermore, integrating air bypass function into the communication components in this embodiment increases the number of face mask ports and improves the user experience.
