The low-noise breathing mask can further effectively improve the problem of blowing the bed partner and noise of the exhaust gas, and improve the comfort of the patient and the bed partner during the treatment process.

[0029] Among them, the sealing gasket 11 is a flexible piece, which can be made of silica gel, used for contacting the face of the wearer and forming a seal, having a fitting side for contacting the face of the human body, the fitting side is provided with a first opening capable of accommodating the nose and mouth of the wearer, and the second opening opposite to the fitting side is communicated with the first opening; the bracket 12 has a larger hardness, which can be made of transparent plastic material, used for supporting the sealing gasket 11 and connected with the frame 21, the sealing gasket 11 is connected with the bracket 12 by using adhesive or / and secondary injection molding, the bracket 12 is provided with a third opening matched with the second opening, and the first air hole 121 for receiving pressurized gas.

[0030] As Figure 5As shown, in the low-noise breathing mask provided by this utility model, the main frame assembly 2 includes a frame 21 and a bent tube mounting component 22. The frame 21 is provided with a second ventilation hole 211, and the bent tube mounting component 22 is snapped into the second ventilation hole 211. The second ventilation hole 211 is connected to the first ventilation hole 121. The frame 21 is provided with a slot 23, and the bracket 12 is provided with a boss 14 that cooperates with the slot 23. The frame 21 has a plurality of exhaust holes 24 that are spaced apart and communicate with the U-shaped groove 122.

The connecting fabric cover 27 is made of soft fabric, making it more comfortable for the patient to wear.

[0032] like Figure 6 and Figure 7 As shown, in the low-noise breathing mask provided by this utility model, the curved tube assembly 3 includes a curved tube 31, an anti-asphyxiation valve 32, an inner ring 33, and a pipe connector 34. The curved tube 31 is provided with a ventilation groove 311, and the bottom of the curved tube 31 is provided with an arc-shaped mounting member 312. The arc-shaped mounting member 312 is inserted into the curved tube mounting member 22 and can rotate within the curved tube mounting member 22. The anti-asphyxiation valve 32 is installed in the mounting groove 313 of the curved tube 31, and the inner ring 33 is installed in the curved tube 31. One end of the pipe connector 34 is connected to the curved tube 31 by a snap-fit, and the other end is used to connect to a breathing support device to deliver breathing gas. The inner sleeve 33 is installed inside the bend 31. When the ventilator stops working, the patient exhales waste gas, and the airflow blows towards the anti-asphyxiation valve 32, causing it to come into close contact with the inner sleeve 33, thereby closing the passage of waste gas to the breathing tubing and allowing the gas to be discharged through the ventilation slot 311, preventing the patient from re-inhaling waste gas due to its residue in the tubing. Because the arc-shaped mounting piece 312 at the bottom of the bend 31 is inserted into the bend mounting piece 22, and the arc-shaped surface of the arc-shaped mounting piece 312 fits and mates with the inner arc surface of the bend mounting piece 22, the bend assembly 3 can rotate freely within the bend mounting piece 22 during use to adapt to different application environments.

[0033] Further, in the low-noise breathing mask, the inner ring sleeve 33 is a thin-walled part, the contact surface of the inner ring sleeve 33 and the anti-choking valve 32 is a slope, and two air outlet grooves 331 are arranged on the slope and separated by a partition plate. The slope of the inner ring sleeve 33 is used to abut against the anti-choking valve 32 and play a limiting role, and the two air outlet grooves 331 arranged on the slope are separated by a partition plate, so that when the patient exhales a large amount of air, the partition plate increases the rigidity of the anti-choking valve 32, so that the anti-choking valve 32 is tightly attached to the inner ring sleeve 33, and the sealing performance is improved.

[0034] Further, in the low-noise breathing mask, the inner ring sleeve 33 is a thin-walled part, the contact surface of the inner ring sleeve 33 and the anti-choking valve 32 is a slope, and two air outlet grooves 331 are arranged on the slope and separated by a partition plate. The slope of the inner ring sleeve 33 is used to abut against the anti-choking valve 32 and play a limiting role, and the two air outlet grooves 331 arranged on the slope are separated by a partition plate, so that when the patient exhales a large amount of air, the partition plate increases the rigidity of the anti-choking valve 32, so that the anti-choking valve 32 is tightly attached to the inner ring sleeve 33, and the sealing performance is improved.

[0035] Preferably, in the low-noise breathing mask, the sound-absorbing part 13 is filter cotton or a noise reduction net, and the thickness of the sound-absorbing part 13 is about 1-5 mm, preferably 3 mm. The filter cotton or the noise reduction net has good air permeability, and the thickness of the sound-absorbing part 13 should not be too thick. On the one hand, too thick sound-absorbing part 13 will reduce the air permeability of the gas, thereby failing to achieve the effect of exhaust. On the other hand, too thick sound-absorbing part 13 will affect the overall weight of the mask.

[0036] Further preferably, in the low-noise breathing mask, the diameter of the exhaust hole 24 is 0.6-0.9 mm, preferably 0.6 mm, and the diameter of the exhaust hole 24 gradually increases from inside to outside along the exhaust direction. The exhaust direction is perpendicular to the outside relative to the face of the wearer, and the diameter of the exhaust hole 24 gradually increases from inside to outside along the exhaust direction in a divergent manner to facilitate the patient to exhaust, and also facilitate the mold forming of the breathing mask. The exhaust direction is set to be perpendicular to the outside relative to the face of the wearer, and when in use, the gas exhaled by the wearer can be discharged in time through the exhaust hole 24 on the frame 21 after entering the gas chamber, and the exhaust direction is divergent, which is conducive to reducing noise and will not blow to the bed partner.
