Description

Technical Field

[0001] This application relates to the field of air respirator face mask technology, and in particular to an air respirator face mask for quickly fixing a Bluetooth microphone. Background Technology

[0002] Air respirators are commonly used equipment in fire fighting or emergency rescue operations. Workers need to breathe through a mask in conjunction with the air respirator, and they also need to communicate and collaborate with other workers through a Bluetooth microphone inside the mask, thereby increasing the efficiency of fire fighting in fire scenarios.

[0003] Existing air respirator masks include a mask body, a mouth and nose mask installed on the lower side of the mask body, and a Bluetooth microphone installed on the outside of the mouth and nose mask. The mouth and nose mask is fixed to the mask body as a whole, and the Bluetooth microphone is magnetically attached to the outside of the mouth and nose mask. When the staff uses the air respirator mask, the staff puts the mask on their head, at which time the mouth and nose mask is located in the staff's mouth area. When the staff uses the air respirator mask to communicate, the staff points the Bluetooth microphone and communicates.

[0004] The aforementioned Bluetooth microphone is located on the outside of the mouth and nose mask, obstructing the lower field of vision of the staff, thus affecting the staff's full field of vision and binocular field of vision, which needs to be improved. Utility Model Content

[0005] In order to reduce obstruction of the worker's lower field of vision by changing the installation method of the Bluetooth microphone, thereby increasing the worker's full field of vision and binocular field of vision, this application provides an air respirator mask for quickly fixing the Bluetooth microphone.

[0006] This application provides an air respirator mask for quickly fixing a Bluetooth microphone, which adopts the following technical solution:

[0007] An air respirator mask for quickly fixing a Bluetooth microphone includes a base, a lens mounted on the outside of the base, and a mouth and nose mask mounted on the lower side of the base. The lens abuts against the side wall of the mouth and nose mask, and a receiving cavity is provided on the upper side of the mouth and nose mask. The Bluetooth microphone is detachably fixed to the inner wall of the receiving cavity.

[0008] By adopting the above technical solution, when staff use air respirator masks for firefighting, the staff can install the Bluetooth microphone on the inner wall of the cavity. At this time, the protruding structure on the upper side of the mouth and nose mask has a low impact on the staff's field of vision. The staff can also remove the Bluetooth microphone to reduce exhalation resistance and thus increase the smoothness of breathing. This setting reduces the obstruction of the staff's lower field of vision by changing the installation method of the Bluetooth microphone, thereby increasing the staff's full field of vision and binocular field of vision.

[0009] Optionally, the mouth and nose mask includes a mask body, a connection port disposed on the outside of the mask body, a vibrating diaphragm installed on the lower side of the mask body, air inlets disposed on both sides of the mask body, inverted teeth fixed to the inner wall of the mask body, and an air outlet opened on the lower side of the mask body. The connection port communicates with the inner wall of the lens, the vibrating diaphragm is used to transmit sound, the air inlets communicate with the inner wall and the outer side of the mask body, the inverted teeth are located on the inner wall of the receiving cavity, and the side wall of the inverted teeth can abut against the side wall of the Bluetooth microphone.

[0010] By adopting the above technical solutions, the diaphragm design increases the efficiency of sound transmission, the connection port design facilitates the connection of the air respirator's tubing to the inside of the air respirator mask, the air inlet and outlet design facilitate the breathing of the staff, and the toothed design reduces the possibility of the Bluetooth microphone falling off during use, thereby increasing the stability of the air respirator mask during use.

[0011] Optionally, a soft layer is fixed to the upper side of the mouth and nose mask, and the soft layer is arranged along the circumference of the mask body.

[0012] By adopting the above technical solution, the soft layer reduces the pressure of the mask on the face of the worker when using the air respirator mask for a long time, thereby increasing the comfort of using the air respirator mask.

[0013] Optionally, the sidewall of the substrate is provided with several elastic bands, and a back cover is fixed to the side of the elastic bands away from the substrate.

[0014] By adopting the above technical solution, the elastic band and rear cover design reduce the possibility of the air respirator mask sliding on the worker's face, further increasing the stability of the air respirator mask during firefighting.

[0015] Optionally, a buckle is installed on the side of the elastic band near the base, and the buckle can lock the elastic band.

[0016] By adopting the above technical solution, the buckle design makes it easier for staff to lock the elastic band, thereby improving the reliability of the elastic band and the back cover and increasing the safety of staff during the fire extinguishing process.

[0017] Optionally, a positioning rope is fixed to the lower side of the base, with both ends of the positioning rope fixed to the two sides of the base respectively, and the positioning rope is located on the side of the base close to the rear cover.

[0018] By adopting the above technical solution, the positioning rope makes it easier for staff to position the air respirator mask, thereby simplifying the process of staff wearing the air respirator mask and making it easier for staff to use.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. When the staff uses the air respirator mask, the staff will attach the Bluetooth microphone to the inner wall of the receiving cavity. At this time, the air respirator mask can communicate through the Bluetooth microphone during use. The staff can remove the Bluetooth microphone from the inner wall of the receiving cavity, thereby making the air circulation inside the air respirator mask smoother. This setting reduces the obstruction of the staff's lower field of vision by changing the installation method of the Bluetooth microphone, thereby increasing the staff's full field of vision and binocular field of vision.

[0021] 2. When wearing an air respirator mask, the staff can position the mask above their head using a positioning rope, and then secure the back of the mask to the back of the head using an elastic cord and buckle. This feature improves the stability of the air respirator mask during operation, thereby increasing the safety of the staff during firefighting. Attached Figure Description

The inner wall of the receiving cavity 4 is detachably fixed with a Bluetooth microphone 5.

[0029] Reference Figure 1 and Figure 2 A soft layer 6 is fixed to the side wall of the mouth and nose mask 3. The soft layer 6 is arranged around the circumference of the mouth and nose mask 3. The side wall of the soft layer 6 can abut against the face of the staff. Several elastic bands 7 are fixed to the side of the base 1 away from the lens 2. In this embodiment, five elastic bands 7 are preferred. One elastic band 7 is located on the upper side of the base 1. The four elastic bands 7 are evenly spaced and fixed to the side wall of the base 1 by adhesive. A back cover 8 is fixed to the side of the elastic band 7 away from the base 1. The back cover 8 can abut against the back of the staff's head. A buckle 9 is provided near the base 1 of the elastic band 7. The inner wall of the buckle 9 can abut against the side wall of the elastic band 7, thereby realizing the limiting function of the elastic band. A positioning rope 10 is fixed to the lower side of the base 1 by adhesive. The two ends of the positioning rope 10 are fixed to the two sides of the base 1 by adhesive. The inner wall of the positioning rope 10 can abut against the neck of the staff.

[0030] Reference Figure 2 and Figure 3 The mouth and nose mask 3 includes a mask body 31 that is snapped and fixed to the lower side of the base 1, a connection port 32 opened on the outside of the mask body 31, a vibrating diaphragm 33 that is snapped and fixed to the lower side of the mask body 31, an air inlet 34 installed on both sides of the mask body 31, a number of inverted teeth 35 fixed to the inner wall of the mask body 31, and an air outlet 36 opened on the lower side of the mask body 31.
