[0026] See also Figures 1 to 4 The breathing mask 100 provided in the embodiment of the present application is adapted to fit the user's mouth and / or nose to provide a breathing airflow to the breathing apparatus 200. The breathing mask 100 includes a main body 1, an exhalation check valve 2, an inhalation check valve 3, and a sealing member 4. The main body 1 is provided with a first opening 11 and a second opening 12. The exhalation one-way valve 2 is arranged in the first opening 11, and the exhalation one-way valve 2 includes a first valve flap 21 and a first stopper 22. The first valve flap 21 is close to the outside of the main body 1, and the first stopper 22 is close to the inside of the main body 1. The exhalation one-way valve 2 is used to allow exhaled air to flow out of the main body 1 through the first opening 11 in one direction; the inhalation one-way valve 3 is arranged in the second opening 12, and the inhalation one-way valve 3 includes a second valve flap 31 and a second stopper 32. The second valve flap 31 is close to the inside of the main body 1, and the second stopper 32 is close to the outside of the main body 1. The inhalation one-way valve 3 is used to allow external gas to flow into the main body 1 through the second opening 12 in one direction, and the sealing member 4 can selectively seal the first opening 11 or the second opening 12.

[0027] The respiratory mask 100 can be a mouth mask, covering the user's mouth, allowing exhalation or inhalation through the mouth. The respiratory mask 100 can be a nasal mask, covering the user's nose, allowing exhalation or inhalation through the nose. The respiratory mask 100 can be an oronasal mask, covering both the user's mouth and nose, allowing the user to freely choose to use either the mouth or nose to provide exhalation or inhalation. When wearing a nasal mask and exhaling through the nasal mask, the user can inhale through the mouth. When inhaling through the nasal mask, the user exhales through the mouth. When wearing a mouth mask and exhaling through the mouth mask, the user inhales through the nose. When inhaling through the mouth mask, the user exhales through the nose.

[0028] When wearing a mask, you can choose to breathe in or out through your mouth or nose. When wearing a mask, you can choose to breathe in or out through your mouth or nose. The specific breathing mode is selected according to training needs.

[0029] See also Figure 4 The respiratory device 200 refers to a device that requires the user to provide a breathing airflow to work, such as a breathing trainer, a breathing exerciser, a snoring device, a sinusitis treatment device, etc., and also includes an oxygenator, a nebulizer and other devices related to breathing airflow.

[0030] In this embodiment, the main body 1 includes sealing surfaces 13 and connecting ports 14 at both ends.

[0031] See also Figure 2 The sealing surface 13 is made of a soft material, such as silicone or TPU, and is primarily used to seal around the nasal cavity, the oral cavity, or both. The shape of the sealing surface 13 can be varied to provide a seal that fits snugly around the oral cavity, the nasal cavity, or both. For example, the sealing surface 13 can be shaped nearly triangular to conform to the contours of the human face. The entire mask body can be made of a soft material.

[0032] The connection port 14 is used to connect the main body 1 and the breathing apparatus 200. The connection port 14 is located substantially at the center of the main body 1. The first opening 11 and the second opening 12 are formed in the main body 1 and are located around the connection port 14.

[0033] See also Figure 3 The shape of the first opening 11 is not limited and can be approximately fan-shaped. The first valve flap 21 and the first stopper 22 in the hole are also set to match the shape of the first opening 11. The first valve flap 21 is close to the outside of the main body 1, and the first stopper 22 is close to the inside of the main body 1. The first valve flap 21 and the first stopper 22 are close to each other and can also fit each other. In this way, the first stopper 22 can block the first valve flap 21 from opening to the inside of the main body 1 without preventing the first valve flap 21 from opening to the outside of the main body 1. The first valve flap 21 opens in one direction when the air flows out from the inside to the outside through the first opening 11, that is, it allows the exhaled air to flow out and stops the inhaled air from entering from the first opening 11.

[0034] The structure of the first valve flap 21 is not limited, and it can be a film or a sheet, as long as it can be opened by airflow to expose the pores of the opening.

[0035] The structure of the first stopper 22 is not limited, as long as it can prevent the first valve flap 21 from opening in the direction in which it is located. In this embodiment, the first stopper 22 includes a plurality of bars 220 arranged along the cross section of the first opening 11.

[0036] The shape of the second opening 12 is not limited and can be approximately fan-shaped. The second valve flap 31 and the second stopper 32 in the hole are also set to match the shape of the second opening 12. The second valve flap 31 is close to the inside of the main body 1, and the second stopper 32 is close to the outside of the main body 1. The second valve flap 31 and the second stopper 32 are close to each other and can also fit each other. In this way, the second stopper 32 can block the second valve flap 31 from opening to the outside of the main body 1 without preventing the second valve flap 31 from opening to the inside of the main body 1. The second valve flap 31 opens in one direction when the air flows from the outside to the inside through the second opening 12, that is, it allows inhalation to enter and stops exhalation from entering from the second opening 12.

[0037] In this embodiment, the second valve flap 31 is a thin sheet, which includes a first surface 311 and a second surface 312 facing each other. The first surface 311 is smooth, and two protrusions 313 are provided on the second surface 312. The two protrusions 313 are used to insert the second stopper 32 so that the sheet and the second stopper 32 are relatively fixed on one side of the protrusion 313, while the side without the protrusion 313 can be blown open by the airflow and without the second stopper 32 to allow the airflow to pass through.

[0038] The structures of the first valve flap 21 and the first stopper 22 may be the same as or similar to the structures of the second valve flap 31 and the second stopper 32 .

[0039] When performing exhalation training, the exhalation check valve 2 does not need to be opened, and only exhaled air is allowed to enter the breathing apparatus 200 from the connecting port 14. Therefore, the first opening 11 is sealed with the sealing member 4, and the second opening 12 is opened.

[0040] When performing inhalation training, the inhalation check valve 3 does not need to be opened, and only inhaled air is allowed to enter the mask body from the connecting port 14. Therefore, the second opening 12 is sealed with the sealing member 4, and the first opening 11 is opened.

[0041] There can be only one sealing member 4, as long as it can seal both the first opening 11 and the second opening 12. Two sealing members 4 can also be provided, with a corresponding sealing member 4 being prepared for each opening.

[0042] By connecting the breathing mask 100 and these breathing devices 200, the exhalation one-way valve 2 is used to allow the exhaled air to flow out of the breathing mask 100, which is suitable for ventilation during inhalation training. The inhalation one-way valve 3 is used to allow the inhaled air to flow into the breathing mask 100, which is suitable for ventilation during exhalation training. The user can use one breathing mask 100 to perform both exhalation training and inhalation training without switching between different breathing masks 100. Regardless of the breathing mode, ventilation can be easily performed, thereby avoiding problems such as dizziness and decreased metabolic efficiency caused by carbon dioxide remaining in the body for too long, thereby improving training efficiency.

[0043] In some embodiments, the opening area of ​​the inhalation check valve 3 is larger than the opening area of ​​the exhalation check valve 2, and the opening area of ​​the inhalation check valve 3 is greater than 57 square millimeters, allowing the user to quickly replenish oxygen. The average human intake area is 40 square millimeters to 57 square millimeters. This configuration ensures a normal level of inhalation for the user. The opening area of ​​the inhalation check valve 3 refers to the area of ​​the opening formed when the first valve flap 21 is open, and may be equal to or smaller than the area of ​​the second opening 12. The opening area of ​​the exhalation check valve is similar.

[0044] The number of the inhalation one-way valve 3 and the exhalation one-way valve 2 can also be set as needed. For example, there can be one or more inhalation one-way valves 3 and one or more exhalation one-way valves 2.

[0045] In some embodiments, the respiratory mask 100 can be directly placed on the connection portion of the external respiratory device 200 through the connection port 14 to achieve connection.

[0046] See also Figure 5 In another embodiment, the respiratory mask 100 is provided with a first positioning portion 15, and correspondingly, the external respiratory device 200 is provided with a second positioning portion 201. In this way, the first positioning portion 15 and the second positioning portion 201 can be used to properly connect the two by cooperating with each other to prevent the two from moving relative to each other in the circumferential direction. Figure 4 The breathing apparatus 200 provided in this embodiment may be a multifunctional breathing trainer, and a second positioning portion 201 is provided at one or both ends of the connection portion.

[0047] In some embodiments, the first positioning portion 15 and the second positioning portion 201 are interference-fitted, and the interference-fit can prevent the main body 1 from axially moving relative to the connecting port 14 and falling off due to shaking during use.

[0048] See also Figure 5In some embodiments, the first positioning portion 15 is a positioning groove, and correspondingly, the second positioning portion 201 can be a positioning post. The positioning groove is formed on the inner wall 16 of the connecting port 14, and the bottom surface 150 of the positioning groove extends outward from the respiratory mask 100 relative to the inner wall 16.

[0049] Because the positioning slot is recessed relative to the inner wall 16, the thickness of this portion of the inner wall 16 is thinner than the rest of the wall. When the positioning post and the positioning slot form an interference fit, the post expands outward. Since the thickness of the positioning slot's bottom surface 150 is relatively thin, the thinner portion experiences greater deformation for the same interference fit. This causes the thinner portion to retract relative to the thicker portion, reducing the contact area between the slot bottom surface 150 and the housing, potentially leading to air leakage and affecting performance. Therefore, the positioning slot's bottom surface 150 can be extended slightly outward relative to the inner wall 16 to compensate for the retracted area. This way, when the respiratory mask 100 and the external respiratory device 200 are connected, the positioning slot retracts inward to compensate, allowing the thinner and thicker portions to fit roughly flush against the bottom of the connection, ensuring equal contact areas between the respiratory mask 100 and the external respiratory device 200, and thus ensuring a good seal. In some embodiments, the length of the slot bottom 150 extending outward relative to the inner wall 16 ranges from 0.5 mm to 2 mm.

[0050] See also Figure 6 In another embodiment, the main body 1 includes a sealing surface 13 and a stepped connecting portion 17 at both ends. The sealing surface 13 is used to fit the contour of the user's mouth and nose, and the stepped connecting portion 17 is used to connect to other respiratory devices 200.

[0051] The stepped connecting portion 17 includes a first circumferential wall 171 and a second circumferential wall 172. The first circumferential wall 171 defines a first inner cavity 173, and the second circumferential wall 172 defines a second inner cavity 174. The first circumferential wall 171 is closer to the sealing surface 13 than the second circumferential wall 172. The diameter of the second inner cavity 174 is larger than the diameter of the first inner cavity 173, so that the respiratory mask 100 can be connected to respiratory devices 200 of different sizes.

[0052] The respiratory mask 100 may be provided with a first positioning portion 15 and the respiratory device 200 may be provided with a second positioning portion 201 . The first positioning portion 15 is configured to cooperate with the second positioning portion 201 to prevent the respiratory mask 100 and the respiratory device 200 from sliding relative to each other.

[0053] In some embodiments, the first positioning portion 15 is a positioning groove, which is formed in the first peripheral wall 171. Correspondingly, the second positioning portion 201 is a positioning post.

[0054] In other embodiments, the first peripheral wall 171 and the second peripheral wall 172 may also have smooth surfaces and be directly sleeved on appropriate connection parts.

[0055] In each of the above embodiments, the number of the first positioning portions 15 and the number of the second positioning portions 201 are equal. The positions of the positioning grooves and the positioning posts can also be interchanged, which is considered a simple variation of the above embodiments.

[0056] Compared with the existing technology, users can use the breathing mask provided by this application to achieve exhalation training and treatment, as well as inhalation training and treatment, without having to switch to different breathing masks. Regardless of the breathing mode, users can easily breathe, avoiding problems such as dizziness and decreased metabolic efficiency caused by carbon dioxide staying in the body for too long, thereby improving training efficiency.
