[0002] A respiratory mask is a medical device used to provide assisted breathing support to patients with impaired respiratory function, including providing high-concentration oxygen, continuous positive pressure ventilation, intermittent positive pressure ventilation, drug nebulization inhalation, etc., to help improve hypoxic conditions, maintain airway patency, and relieve symptoms such as respiratory failure. It is an important treatment method commonly used in clinical practice. Doctors will choose the appropriate mask type based on the patient's specific condition.

[0003] The existing patent CN115430114B discloses a lung exhalation training device for cardiothoracic surgery, including a breathing mask, an adjustment chamber, an air outlet size adjustment device, a manual adjustment mechanism and a manual locking mechanism; the adjustment chamber includes a rear end cover, a middle chamber and a front end cover; the air outlet size adjustment device is arranged in the middle chamber; the manual adjustment mechanism drives the air outlet size adjustment device to work; the manual locking mechanism is used to lock the manual adjustment mechanism glue.

[0004] In order to solve the problem of large size and inconvenient movement of the equipment, this patent covers the breathing mask on the face through a handheld adjustment chamber, making it convenient to carry and thus easier for users to use outdoors.

[0005] However, in actual use, the following deficiencies still exist, for example: in the process of using a breathing mask, due to the fact that the design of the air inlet and outlet channels of some masks is not optimized enough, there are narrow or curved structures, which will increase the resistance to airflow, especially when deep breathing is required. The existing breathing mask structure may cause insufficient inhaled air, thereby affecting the effect of deep breathing. This situation may cause breathing difficulties for users who need to wear masks for a long time, or for people who are doing high-intensity labor or are patients.

[0006] The present invention therefore provides a breathing mask.

The combination of the positioning assembly 6 and the sealing assembly 7 ensures that the mask is firmly worn;

[0046] The auxiliary air supply component 2 includes a mounting plate 21 and an air supply bag 26, one end of the mounting plate 21 is fixedly connected to a two-way telescopic cylinder 22, both ends of the mounting plate 21 close to the two-way telescopic cylinder 22 are fixedly connected to a limiting block 23, the driving end of the two-way telescopic cylinder 22 is fixedly connected to a pull rod 24, the end of the pull rod 24 away from the two-way telescopic cylinder 22 is rotatably connected to a compression block 25, the end of the compression block 25 away from the pull rod 24 is in contact with the outer side of the air supply bag 26, the outer side of the pull rod 24 is slidably connected to the inside of the limiting block 23, the mounting plate 21 plays a supporting and fixing role, it provides a solid foundation for other parts of the component to ensure that each component can be accurately operated in the specified position, the two-way telescopic cylinder 22 as the core driving mechanism, can perform two-way telescopic movement, this design allows the two-way telescopic cylinder 22 to be accurately moved in two directions The movement of the pull rod 24 is controlled to realize effective compression and expansion of the air supply bag 26. The limit block 23 plays a guiding and limiting role to prevent the pull rod 24 from being offset or loosened during the telescopic process, ensuring the stability and accuracy of the movement. The function of the pull rod 24 is to convert the telescopic movement of the two-way telescopic cylinder 22 into the linear movement of the compression block 25, and then act on the air supply bag 26. The end of the pull rod 24 away from the two-way telescopic cylinder 22 is rotatably connected to the compression block 25. The design of the rotatable connection increases the flexibility of the entire component, so that the compression block 25 contacts the air supply bag 26 at different angles, thereby controlling the gas discharge and intake of the air bag. This process can be precisely controlled by adjusting the telescopic speed and distance of the two-way telescopic cylinder 22, ensuring that the air supply bag 26 can respond quickly when necessary and provide sufficient airflow to meet the user's breathing needs.

This connection ensures that oxygen can smoothly enter the entire air supply device from the oxygen tank 11. The outside of the air intake ring 41 is fixedly connected with an air distribution pipe 42. The function of the air distribution pipe 42 is to divert the oxygen delivered from the air intake ring 41 so that it can enter subsequent components through different channels. The air intake valve 43, as a key control element, plays a role in one-way flow control. The air inlet valve 43 ensures that oxygen can only pass through in one direction, thereby preventing the occurrence of backflow and ensuring the safety and continuity of air supply. The air supply bag 26 is a buffer device in the entire air supply device. Its existence can effectively adjust and alleviate pressure fluctuations during the oxygen supply process, ensuring that the user can obtain a stable oxygen flow rate. The oxygen humidifier 44 has the function of adding humidity to the oxygen during the air supply process to prevent discomfort or damage to the respiratory tract caused by long-term inhalation of dry oxygen. The humidified oxygen not only improves the user's comfort, but also reduces the probability of problems related to the respiratory device. The delivery pipe 45 serves as a transmission path to deliver the humidified oxygen to the air supply pipe 46. The outer side of the air supply pipe 46 is fixedly connected to the end of the entire air supply device, and finally delivers the treated oxygen to the user's respiratory device. This transmission process ensures that the oxygen can directly and efficiently reach the user's respiratory device after humidification, ensuring the quality and effect of oxygen supply.

[0048] like Figure 1 -and Figure 4As shown: In this scheme, the auxiliary air outlet component 3 includes a two-way telescopic cylinder 2 31 and an air outlet airbag 38.

The driving end of the two-way telescopic cylinder 2 31 is slidably connected with a pulling block 32. The end of the pulling block 32 away from the two-way telescopic cylinder 2 31 is fixedly connected with a pulling plate 33. The two sides of the pulling plate 33 are fixedly connected with a rotating column 34. The outer side of the rotating column 34 is rotatably connected with a pulling rod 2 35. The outer side of the pulling rod 2 35 is slidably connected with a positioning block 3 6. The end of the pull rod 2 35 away from the rotating column 34 is rotatably connected with the compression block 2 37. The end of the compression block 2 37 away from the pull rod 2 35 is in contact with the outer side of the air outlet airbag 38. The auxiliary air outlet component 3 includes a two-way telescopic cylinder 2 31. The outer side of the cylinder is installed on the other side of the mounting plate 21, that is, on the side away from the two-way telescopic cylinder 1 22. The driving end of the two-way telescopic cylinder 2 31 is connected to the pulling block 32 by a sliding connection. This design ensures that the pulling block 32 can move smoothly under the drive of the cylinder, thereby transmitting power. The pull plate 33 not only serves as a power transmission point, but also realizes coordinated operation with the entire assembly through the rotating columns 34 on both sides. The outer side of the rotating column 34 is connected to the pull rod 2 35, and the pull rod 2 35 can slide inside the positioning block 36. This sliding connection design allows the pull rod 2 35 to flexibly adjust its position according to the driving action of the two-way telescopic cylinder 2 31, thereby driving subsequent operations. When the two-way telescopic cylinder 2 31 drives the pulling block 32, the pull rod 2 35 will pull the compression block 2 37. The function of the compression block 2 37 is to communicate with the outlet gas The outer sides of the airbag 38 are in contact with each other, and appropriate pressure is applied to the airbag during the movement. Through this process, the compression block 2 37 can accurately control the compression degree of the airbag 38, thereby adjusting the air discharge amount in the airbag, that is, when the user needs to exhaust, the two-way telescopic cylinder 2 31 will drive the compression block 2 37 to apply greater pressure to the airbag 38, thereby increasing the exhaust amount of the airbag. On the contrary, when the exhaust amount needs to be reduced, the compression block 2 37 will reduce the pressure on the airbag, so that the air discharge speed in the airbag is slowed down;

[0049] like Figure 1 , Figure 3 and Figure 4As shown: the one-way air intake component 5 includes an air outlet valve 51, one end of the air outlet valve 51 is installed on the air outlet airbag 38, the other end of the air outlet valve 51 is fixedly connected to a connecting pipe 52, the end of the air outlet airbag 38 away from the air outlet valve 51 is fixedly connected to an exhalation valve 53, the outer side of the connecting pipe 52 is fixedly connected to an air outlet pipe 54, the air outlet valve 51 is one of the key control components, one end of which is installed on the air outlet airbag 38, the main function of the air outlet valve 51 is to control the one-way flow of exhaust gas, to ensure that the gas can only flow out from the air outlet airbag 38, and no external gas will flow back into the air outlet airbag 38, to ensure the single direction of gas discharge, and effectively prevent the backflow problem, the other end of the air outlet valve 51 is fixedly connected to the connecting pipe 52, The connecting pipe 52 plays a role in gas transmission, further guiding the exhausted gas from the outlet valve 51 to the next component. The setting of the connecting pipe 52 ensures that the exhausted gas can pass smoothly, reduces the resistance in the gas flow process, and maintains the smoothness of the air flow. The function of the exhalation valve 53 is to discharge the gas into the external environment when the gas accumulated in the outlet airbag 38 reaches a certain pressure. The design of the exhalation valve 53 can not only control the gas discharge rhythm, but also ensure that the exhausted gas is discharged at a stable rate to prevent excessive pressure inside the device due to gas retention. The outlet pipe 54 is the end of the gas discharge path, which is responsible for finally discharging the gas processed by the outlet valve 51 and the exhalation valve 53 out of the device;

[0050] like Figure 4 and Figure 5 As shown: the positioning assembly 6 includes an extension plate 61, the outer side of the positioning block 36 is fixedly connected to the extension plate 61, the outer side of the extension plate 61 is fixedly connected to the two ends of the mounting plate 21, the end of the extension plate 61 away from the mounting plate 21 is fixedly connected to an airbag gasket 1 62, the four outer corners of the mounting plate 21 are fixedly connected to airbag gaskets 2 63, the outer side of the airbag gasket 1 62 is fixedly connected to one end of the air outlet airbag 38, the outer side of the airbag gasket 2 63 is fixedly connected to one end of the air supply airbag 26, the extension plate 61 provides a solid installation foundation, thereby enhancing the overall stability of the positioning assembly 6, by fixing the airbag gasket 1 62 to one end of the air outlet airbag 38, it can be ensured that the position of the air outlet airbag 38 in the system is not affected by external forces and is not offset or falling off, the role of the airbag gasket 2 63 is to provide multiple stable connection points for the air supply airbag 26, which can effectively fix the air supply airbag 26 on the mounting plate 21;

[0051] like Figure 1 and Figure 6As shown: the sealing assembly 7 includes a mask sealing pad 71, the outer side of the mask sealing pad 71 is fixedly connected to the inside of the breathing mask body 12, one end of the air supply pipe 46 is fixedly connected to the oxygen inlet pipe 72, the inside of the mask sealing pad 71 is fixedly connected to the breathing valve 73, the outer side of the oxygen inlet pipe 72 is fixedly connected to the mask sealing pad 71, the mask sealing pad 71 is a soft and elastic material, which can fit tightly on the user's face to form an effective seal, and the outer side of the mask sealing pad 71 is fixedly connected to the inside of the breathing mask body 12. This connection method ensures the stability between the mask sealing pad 71 and the mask body, so that the mask can be kept in the process of wearing. Maintain a good sealing effect, and there will be no leakage due to the movement of the mask or changes in the face. Then the oxygen inlet pipe 72 can be stably transported to the inside of the mask through the air supply pipe 46. The oxygen inlet pipe 72 is responsible for introducing the externally supplied oxygen into the mask to provide fresh oxygen for the user. At the same time, the function of the breathing valve 73 is to control the in and out of the gas, so that oxygen enters the mask through the oxygen inlet pipe 72, while preventing external air from entering the mask to avoid oxygen waste and pollution. This internal fixed connection design enables the breathing valve 73 to accurately control the airflow, ensuring that the user can breathe smoothly, while keeping the oxygen concentration in the mask at an appropriate level.

[0052] Working principle:

[0053] like Figure 1 - Figure 6 As shown:

[0054] When in use: the oxygen tank 11 of the mask assembly 1 delivers oxygen to the one-way air intake assembly 4 through the air intake ring 41. The air intake ring 41 ensures that oxygen flows smoothly from the oxygen tank 11. Then, the air distribution pipe 42 distributes the oxygen to the air intake valve 43. The air intake valve 43 ensures that oxygen can only enter the air supply bag 26 in one direction to avoid backflow. The air supply bag 26 acts as a buffer device, which adjusts the pressure fluctuation of the oxygen and then humidifies the oxygen through the oxygen humidifier 44 to ensure that the supplied oxygen is appropriately moist. The delivery pipe 45 and the air supply pipe 46 deliver the humidified oxygen to the inside of the mask to ensure that the user breathes comfortable oxygen. At the same time, the two-way telescopic cylinder 22 drives the pull rod 24, and then pulls the compression block 25 to apply pressure to the air supply bag 26, thereby controlling the compression and expansion of the air bag and adjusting the air supply. The limit block 23 The function is to ensure that the movement path of the pull rod 24 is stable, avoid deviation, and make the air supply process smooth. During the exhalation process, the two-way telescopic cylinder 2 31 drives the pulling block 32, and then drives the pulling plate 33 and the pull rod 2 35, so that the compression block 2 37 applies pressure to the air outlet airbag 38, thereby controlling the exhaust volume of the airbag. The outlet valve 51 ensures that the exhausted gas can only flow in one direction to prevent external gas from flowing back. Finally, after being processed by the connecting pipe 52 and the exhalation valve 53, the gas is discharged from the device through the outlet pipe 54. At the same time, the airbag gasket 1 62 and the airbag gasket 2 63 ensure that the position of the air supply and air outlet airbag 38 is stable to prevent displacement during the working process. At this time, the mask sealing pad 71 ensures that the mask fits the user's face tightly to prevent oxygen leakage. At the same time, the breathing valve 73 controls the airflow inside and outside the mask to maintain the oxygen concentration in the mask.
