Description

Technical Field

[0001] The present invention relates to the technical field of respiratory training, in particular to a dynamically sealed respiratory training mask. Background Art

[0002] Deep inspiration breath-hold technique is a technology developed in recent years to control the impact of respiratory movement on the movement of radiotherapy target area. Deep inspiration breath-hold technique is mostly used in patients with left breast cancer and patients with right breast cancer who need internal mammary lymph node irradiation during breast cancer radiotherapy. By deep inspiration breath-holding, the lungs are expanded to increase the distance between the chest wall and the heart, and the heart is moved away from the radiotherapy irradiation field. In this process, patients need to wear various respiratory training management devices to perform standardized free breathing and breath-holding training.

[0003] With existing breathing training masks, when a user opens their mouth to speak or inhale, the movement of the mandible drives the skin in the mouth area to move downward, backward, or to the sides, partially separating from the mouth area of ​​the sealing unit to form a gap. Although this gap can be eliminated immediately when the mouth is closed, it creates a breathing risk. The gap formed during speaking or inhaling can allow a large amount of gas from the external environment, including pathogenic particles therein, to be inhaled into the human body without being filtered. This not only reduces the safety of inhaling air into the user's body, but also affects the airtightness of the breathing training mask, thereby affecting the training effect on the user. Therefore, the present invention provides a dynamically sealed breathing training mask to meet this need. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a dynamically sealed breathing training mask. By setting a dynamic sealing component, the user can still have a good sealing effect between the main body and the user's face when opening the mouth to breathe or speak, and no gap will be generated between the face and the mask when the user opens the mouth. It is ensured that the air inhaled into the patient's body can pass through the filtering mechanism, making the air sufficiently clean. The above setting can solve the problem of low safety of traditional breathing training masks during use.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: A dynamically sealed breathing training mask comprises a main body, an outer shell fixedly connected to the outer wall of the main body, an upper positioning frame fixedly connected to the top inner wall of the main body, a lower positioning frame fixedly connected to the bottom inner wall of the main body, a through hole for breathing training installed on the main body, and wearing mechanisms fixedly connected to both sides of the main body; a dynamic sealing component, which is used to seal between the main body and the cheek when the user opens his mouth to breathe and speak, and the dynamic sealing component is respectively connected to the upper positioning frame and the lower positioning frame.

[0006] Optionally, the dynamic sealing assembly includes an upper frame fixedly connected to both sides of the upper positioning frame, and a lower frame fixedly connected to both sides of the lower positioning frame, and arc-shaped cushions are fixedly connected to both the upper frame and the lower frame.

[0007] Optionally, a nasal bone positioning portion is installed at a middle position of the upper positioning frame, and the contour of the nasal bone positioning portion is adapted to the contour of the human nasal bone.

[0008] Optionally, cheek bone positioning parts are symmetrically installed at both ends of the upper positioning frame, and the contours of the cheek bone positioning parts are adapted to the contours of the cheek bones of the human body.

[0009] Optionally, a first volute sealing gasket is fixedly connected to the top inner wall of the upper positioning frame, and a first fitting surface is installed at one end of the first volute sealing gasket. The upper positioning frame, the nasal bone positioning part and the cheek bone positioning part are an integrally manufactured structure.

[0010] Optionally, a mandibular positioning portion is installed at a middle position of the lower positioning frame, and the contour of the mandibular positioning plate is adapted to the contour of the human mandible.

[0011] Optionally, mandibular positioning parts are symmetrically installed at both ends of the lower positioning frame, and the contour of the mandibular positioning parts is adapted to the contour of the human mandible.

[0012] Optionally, a second volute sealing gasket is fixedly connected to the bottom inner wall of the lower positioning frame, and a second fitting surface is installed at one end of the second volute sealing gasket. The lower positioning frame, the mandibular positioning part and the mandibular positioning part are an integrally manufactured structure.

[0013] Optionally, a first plug is fixedly connected to one end of the upper frame, and a second plug is fixedly connected to one end of the lower frame. A recess is installed on the first plug, and a protrusion is installed on the second plug. The contours of the protrusion and the recess match, and the size of the first plug is larger than that of the second plug.

[0014] Optionally, the arc-shaped cushions are curved arc-shaped structures, and a plurality of the arc-shaped cushions are evenly distributed on the inner walls of the upper frame and the lower frame, and the sizes and thicknesses of the arc-shaped cushions decrease step by step.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, by setting up a dynamic sealing component, the main body and the user's face can still have a good sealing effect when the user opens his mouth to breathe or speak, and no gap will be generated between the face and the mask when the user opens his mouth, ensuring that the air inhaled into the patient's body can pass through the filtering mechanism, making the air clean enough.

[0016] By setting an upper positioning frame in the dynamic sealing component, when the mask is worn, the upper positioning frame is distributed at the user's nasal bone position, and a nasal bone positioning part that adapts to the human nasal bone contour is set at the middle position of the upper positioning frame. The setting of this structure is to allow the user to adapt better during the wearing process. Such a setting can not only improve the fit between the upper positioning frame and the user's facial contour, but also improve the user's comfort during the wearing process. Cheek bone positioning parts that adapt to the human cheek bone contour are also set on both sides of the upper positioning frame. The setting of this structure improves the fit between the two sides of the upper positioning frame and the user's facial contour to a certain extent, thereby ensuring the user's stability during the wearing process.

[0017] By arranging a first volute sealing gasket and a second volute sealing gasket in the dynamic sealing component, the middle of the first volute sealing gasket and the second volute sealing gasket are both volute profile structures, and the functions of the two are the same. Here, the first volute sealing gasket is taken as an example to analyze the function and effect. One end of the first volute sealing gasket is fixed to the inner wall of the upper positioning frame, and the other end is installed with a first fitting surface. The first fitting surface is an arc-shaped curved surface structure. When the user wears the mask, the first fitting surface contacts the user's face. When the user opens his mouth to breathe or speaks, under the mutual pulling action of the upper positioning frame and the lower positioning frame, the first fitting surface will pull the volute structure in the middle of the first volute sealing gasket to deform under the action of friction. The first volute sealing gasket will buffer the pulling force during the deformation process, thereby making it less likely for the upper positioning frame and the lower positioning frame to be misaligned and slipped, thereby ensuring the stability of the structure between the upper positioning frame and the lower positioning frame during the user's opening process, thereby ensuring the sealing effect of the top and bottom of the mask.

[0018] By setting an upper frame and a lower frame in the dynamic sealing assembly, the upper positioning frame and the lower positioning frame of the breathing training mask provided by the present application are not hollow structures, and the two are connected together by the upper frame and the lower fixed fit. Such a setting makes the upper positioning frame and the lower positioning frame not separate independent structures. Under the connection action of the upper frame and the lower frame, a whole support system is formed between the upper positioning frame and the lower positioning frame. This support system can provide all-round support and limitation to the main body of the mask.

[0019] By arranging an arc-shaped cushion in the dynamic sealing component, the end of the arc-shaped cushion away from the upper frame is an inward-turned circular contour. The setting of this contour is to make the end structure of the arc-shaped cushion more rounded, so that the arc-shaped cushion is more comfortable when it contacts the user's face. When the user opens his mouth, the arc-shaped cushion will increase the squeezing force on the user's face. At this time, the circular contour of its end can also ensure the comfort of the user's face. The arc-shaped cushion is distributed in a gradient contour on the upper frame and the lower frame. This arrangement is to adapt to the arc-shaped structure of the upper frame and the lower frame, so that when the user does not open his mouth to speak, the arc-shaped cushion can still tightly contact the user's face, so that the mask has good stability whether the user opens or closes his mouth.

[0029] like Figures 1 to 16As shown, an embodiment of the present invention provides a dynamically sealed breathing training mask, comprising a body 1, a shell 101 fixedly connected to the outer wall of the body 1, an upper positioning frame 2 fixedly connected to the top inner wall of the body 1, a lower positioning frame 3 fixedly connected to the bottom inner wall of the body 1, a through hole for breathing training is installed on the body 1, and a wearing mechanism is fixedly connected to both sides of the body 1; a dynamic sealing component, which is used to seal between the body 1 and the cheek when the user opens his mouth to breathe and speak, and the dynamic sealing component is respectively connected to the upper positioning frame 2 and the lower positioning frame 3. The breathing training mask provided by this application is mainly suitable for deep inhalation breath holding technology, and breathing training masks have already appeared in this technical field. The main body 1 proposed in this application is the main body of the breathing mask. The outer shell 101 outside the main body 1 is mainly used to protect the main body 1. The through holes opened on the main body 1 are used for the user to perform breathing training. The wearing mechanisms installed on both sides of the main body 1 are mainly used to wear the main body 1 on the user's face. Here, the wearing mechanism selects an elastic band structure. In the above structure, the working principles of the main body 1, the outer shell 101 and the wearing mechanism are disclosed as prior art in this application, so they will not be elaborated on. Optionally, a filtering mechanism is set in the main body 1, and the filtering mechanism is used to filter the air inhaled into the main body 1, reduce the content of pollutant particles in the inhaled air, and reduce the damage to the user's respiratory tract caused by breathing training.

[0030] By setting up a dynamic sealing component, the present application can ensure that the main body 1 and the user's face still have a good sealing effect when the user opens his mouth to breathe or speak, and no gap will be generated between the face and the mask when the user opens his mouth, ensuring that the air inhaled into the patient's body can pass through the filtering mechanism, making the air clean enough.

[0031] As an implementation method in this embodiment, Figures 4 to 16As shown, the dynamic sealing assembly includes an upper frame 4 fixedly connected to both sides of the upper positioning frame 2, and also includes a lower frame 5 fixedly connected to both sides of the lower positioning frame 3. The upper frame 4 and the lower frame 5 are fixedly connected with an arc-shaped soft cushion 6. A nasal bone positioning portion 201 is installed at the middle position of the upper positioning frame 2. The contour of the nasal bone positioning portion 201 is adapted to the contour of the human nasal bone. Cheek bone positioning portions 202 are symmetrically installed at both ends of the upper positioning frame 2. The contour of the cheek bone positioning portion 202 is adapted to the contour of the human cheek bone. A first volute sealing gasket 203 is fixedly connected to the top inner wall of the upper positioning frame 2. The first volute sealing gasket 20 One end of 3 is provided with a first fitting surface 204, the upper positioning frame 2, the nasal bone positioning portion 201 and the cheek bone positioning portion 202 are an integrally manufactured structure, and in the dynamic sealing assembly, the upper frame 4 and the lower frame 5 and the arc-shaped cushions 6 on the inner walls of the two are mainly used for sealing, and the upper frame 4 and the lower frame 5 can be deformed accordingly during the user's opening, and in the process of deformation, the structural setting of the arc-shaped cushion 6 is used to achieve a sealing effect. In the above operation, the upper positioning frame 2 and the lower positioning frame 3 are used to drive the upper frame 4 and the lower frame 5 to deform, and the upper positioning frame 2 and the lower positioning frame 3 are both installed in this Inside the body 1, during the actual wearing process, the upper positioning frame 2, the lower positioning frame 3, the upper frame 4 and the lower frame 5 are all provided with rubber cushions. The above-mentioned structure can support and shape the cushions. Among them, the upper positioning frame 2 is installed on the top of the body 1. When the mask is worn, the upper positioning frame 2 is distributed at the position of the user's nasal bone. The middle position of the upper positioning frame 2 is provided with a nasal bone positioning part 201 adapted to the contour of the human nasal bone. The setting of this structure is to allow the user to adapt better during the wearing process. Such a setting can not only improve the fit between the upper positioning frame 2 and the user's facial contour, It can also improve the user's comfort during wearing, and will not cause discomfort due to structural incompatibility. Cheekbone positioning parts 202 that are adapted to the human cheekbone contour are also provided on both sides of the upper positioning frame 2. The setting of this structure improves the fit between the two sides of the upper positioning frame 2 and the user's facial contour to a certain extent, thereby ensuring the user's stability during wearing. The setting of the above structure makes the upper positioning frame 2 adapt to the contours of the human nasal bone and cheekbone in terms of contour, thereby improving the comfort and stability during wearing, so that the user can have a better sealing effect during breathing training.

[0032] Furthermore, the upper positioning frame 2, the nasal bone positioning portion 201 and the cheek bone positioning portion 202 are all integrally manufactured structures, and are made of plastic. This arrangement, on the one hand, makes the processing technology of the upper positioning frame 2 simpler and easier to manufacture during the production process. Moreover, the upper positioning frame 2 made of plastic is low in cost and lightweight in structure, and is more suitable for actual application scenarios when used in a breathing training mask. It can effectively reduce the weight and pressure of the user when wearing the mask, thereby improving the wearing comfort. On the other hand, the structure of the plastic material can be deformed under the pulling action of external force. This arrangement makes it easier for the positioning frame 2, the nasal bone positioning portion 201 and the cheek bone positioning portion 202 to adapt to the facial contour of the human body, thereby improving the sealing and comfort.

[0033] Furthermore, a first volute sealing gasket 203 is installed on the top inner wall of the upper positioning frame 2. The middle of the first volute sealing gasket 203 is a volute profile structure. One end of the first volute sealing gasket 203 is fixed to the inner wall of the upper positioning frame 2, and the other end is installed with a first fitting surface 204. The first fitting surface 204 is an arc-shaped curved surface structure. When the user wears the mask, the first fitting surface 204 contacts the user's face. When the user opens his mouth to breathe or speak, under the mutual pulling action of the upper positioning frame 2 and the lower positioning frame 3, the first fitting surface 204 will pull the volute structure in the middle of the first volute sealing gasket 203 to deform under the action of friction. The volute sealing gasket 203 will buffer the pulling force during the deformation process, making it less likely for dislocation and sliding to occur between the upper positioning frame 2 and the lower positioning frame 3, ensuring the stability of the structure between the upper positioning frame 2 and the lower positioning frame 3 during the user's opening process, thereby ensuring the sealing effect of the top and bottom of the mask. It is worth mentioning that the reason why the first volute sealing gasket 203 is installed on the top of the upper positioning frame 2 is because when the user opens the mouth, the top of the upper positioning frame 2 will be subjected to the pulling force first. Installing the first volute sealing gasket 203 on the top of the upper positioning frame 2 can buffer the pulling force at the first time, thereby ensuring the stability of the upper positioning frame 2.

[0034] In this embodiment, if Figure 4 and Figures 9 to 13As shown, a mandibular positioning portion 301 is installed at the middle position of the lower positioning frame 3, and the contour of the mandibular positioning plate is adapted to the contour of the human mandible. Mandibular positioning portions 302 are symmetrically installed at both ends of the lower positioning frame 3, and the contour of the mandibular positioning portion 302 is adapted to the contour of the human mandible. A second volute sealing gasket 303 is fixedly connected to the bottom inner wall of the lower positioning frame 3, and a second fitting surface 304 is installed at one end of the second volute sealing gasket 303. The lower positioning frame 3, the mandibular positioning portion 301 and the mandibular positioning portion 302 are an integrally manufactured structure. Although the upper positioning frame 2 and the lower positioning are different in structure, their functions are the same. When the user wears the mask, the lower positioning frame 3 is located at the user's At the mandibular position of the lower positioning frame 3, the upper and lower jaw positioning parts 301 and the mandibular positioning part 302 are set to improve the adaptability of the lower positioning frame 3 to the user's face, thereby improving the user's comfort during wearing and the stability of the structure of the lower positioning frame 3 during wearing. The setting of the second volute sealing pad 303 at the bottom of the lower positioning frame 3 has the same function as the setting of the first volute sealing pad 203 on the upper positioning frame 2, both of which are to absorb and buffer the pulling force during the user's opening process, thereby improving the structural stability of the upper positioning frame 2 and the lower positioning frame 3 during the user's opening process, so that the sealing of the top and bottom of the mask remains intact when the user opens the mouth, thereby improving the training effect and the safety of the user inhaling air.

[0035] In this embodiment, if Figures 13 to 16 As shown, one end of the upper frame 4 is fixedly connected to the first plug 401, and one end of the lower frame 5 is fixedly connected to the second plug 501. The first plug 401 is installed with a recessed portion 402, and the second plug 501 is installed with a raised portion 502. The contours of the raised portion 502 and the recessed portion 402 match. The size of the first plug 401 is larger than that of the second plug 501. The arc cushion 6 is a curved arc structure. Multiple arc cushions 6 are evenly distributed on the inner walls of the upper frame 4 and the lower frame 5, and the size and thickness of the arc cushion 6 decrease step by step. As mentioned above, the upper positioning frame 2, the lower positioning frame 3, the upper frame 4 and the lower frame 5 are all wrapped in the outside during actual use. A soft cushion made of rubber material is provided. The above structure is provided to shape and support the soft cushion, thereby improving the sealing effect of the soft cushion on the user's face. Secondly, compared with traditional respiratory training masks, the respiratory training mask provided by the present application is not a hollow structure between the upper positioning frame 2 and the lower positioning frame 3. The two are connected together through the upper skeleton 4 and the lower fixed fit. Such a setting makes the upper positioning frame 2 and the lower positioning frame 3 not separate independent structures. Under the connection action of the upper skeleton 4 and the lower skeleton 5, a whole support system is formed between the upper positioning frame 2 and the lower positioning frame 3. This support system can provide all-round support and limitation to the main body 1 of the mask.

[0036] Specifically, one end of the upper frame 4 is fixed on the upper positioning frame 2, and the other end is clamped together with the lower frame 5. One end of the lower frame 5 is fixed on the lower positioning frame 3, and the other end is clamped together with the upper frame 4. A slot is opened on the surface of the first plug 401 for avoiding the second plug 501, so that the second plug 501 can pass through the first plug 401. Since the contours of the protrusion 502 and the recessed portion 402 are consistent with each other, the two can be engaged together to limit each other. Therefore, after the second plug 501 passes through the first plug 401, the first plug 401 and the second plug 501 can be fixed together under the limiting action of the protrusion 502 and the recessed portion 402. The non-fixed connection between the upper frame 4 and the lower frame 5 makes the overall structure of the mask more flexible, thereby making the mask more convenient and efficient during later maintenance and disassembly.

[0037] Furthermore, both the upper frame 4 and the lower frame 5 are arc-shaped structures. When the two are snapped together, there will be a contour protruding toward the outside of the user's face at the connection position between the two. Arc-shaped cushions 6 are provided on the inner walls of the upper frame 4 and the lower frame 5. The size and thickness of the arc-shaped cushions 6 gradually decrease from the connection position of the upper frame 4 and the lower frame 5 to both ends. The size and thickness of the arc-shaped cushions 6 at the connection position of the upper frame 4 and the lower frame 5 are the largest. When the user opens his mouth, the user's lower jaw will open and drive the lower positioning frame 3 to displace. At this time, the lower positioning frame 3 will pull the lower frame 5. After being subjected to tension, the lower frame 5 will pull the upper frame 4. At this time The upper positioning frame 2 will also receive the pulling force of the upper frame 4. When the pulling force is generated between the upper frame 4 and the lower frame 5, the arc-shaped structures of the two will be deformed. During the deformation process, the raised contour at the connection position of the upper frame 4 and the lower frame 5 will shrink toward the user's face. At the same time, the arc-shaped cushion 6 located at this position will also move toward the user's face. During the movement of the arc-shaped cushion 6, it will contact the user's face and use the squeezing force of the arc-shaped cushion 6 to improve the sealing between the mask and the user's face. This arrangement ensures the sealing of both sides of the mask when the user opens his mouth to speak or breathe, thereby improving the safety and training effect of the entire training process.

[0038] Furthermore, the overall structure of the arc cushion 6 is an arc-shaped structure, and the end of the arc cushion 6 away from the upper frame 4 is an inward-turned circular contour. The setting of this contour is to make the end structure of the arc cushion 6 more rounded, so that the arc cushion 6 is more comfortable when it contacts the user's face. When the user opens his mouth, the arc cushion 6 will increase the squeezing force on the user's face. At this time, the circular contour of its end can also ensure the comfort of the user's face. The arc cushion 6 is distributed in a gradient contour on the upper frame 4 and the lower frame 5. This arrangement is to adapt to the arc-shaped structure of the upper frame 4 and the lower frame 5, so that when the user does not open his mouth to speak, the arc cushion 6 can still tightly contact the user's face, so that the mask has good stability whether the user opens or closes his mouth.

[0039] In the above solution, the arc-shaped cushion 6 and the upper frame 4 are an integrally manufactured structure, and the material is also plastic. Such a setting can not only reduce the manufacturing cost, but also make the user more light and comfortable when wearing the mask.

[0040] The working principle of the technical solution provided by the present invention is as follows: During use, the user utilizes the wearing mechanism to wear the main body 1 on the face. Since a through hole is provided on the main body 1, air passes through the through hole into the user's body when the user breathes, thereby achieving the effect of breathing training. After the mask is worn, the upper positioning frame 2 is distributed at the position of the user's nasal bone. A nasal bone positioning portion 201 adapted to the contour of the human nasal bone is provided at the middle position of the upper positioning frame 2. This structure is provided to allow the user to adapt better during the wearing process. Such a setting can not only improve the fit between the upper positioning frame 2 and the user's facial contour, but also improve the user's comfort during the wearing process. Cheek bone positioning portions 202 adapted to the contour of the human cheek bone are also provided on both sides of the upper positioning frame 2. This structure improves to a certain extent. The two sides of the upper positioning frame 2 fit the contours of the user's face, thereby ensuring the stability of the user during wearing. After the user wears the mask, the lower positioning frame 3 is located at the user's lower jaw. The upper and lower jaw positioning parts 301 and the mandibular positioning part 302 of the lower positioning frame 3 are set to improve the adaptability of the lower positioning frame 3 to the user's face, thereby improving the user's comfort during wearing and the stability of the lower positioning frame 3 structure during wearing. A first volute sealing pad 203 is set on the upper positioning frame 2, and a second volute sealing pad 303 is set on the lower positioning frame 3. The functions of the first volute sealing pad 203 and the second volute sealing pad 303 are the same. Here, the first volute sealing pad 203 is taken as an example to explain the working principle and function of the two. The first volute sealing pad 203 is used as an example to explain the working principle and function of the two. The middle of the volute sealing gasket 203 is a volute profile structure, one end of the first volute sealing gasket 203 is fixed to the inner wall of the upper positioning frame 2, and the other end is installed with a first fitting surface 204, which is an arc-shaped curved surface structure. When the user wears the mask, the first fitting surface 204 contacts the user's face. When the user opens his mouth to breathe or speak, under the mutual pulling action of the upper positioning frame 2 and the lower positioning frame 3, the first fitting surface 204 will pull the volute structure in the middle of the first volute sealing gasket 203 to deform under the action of friction. During the deformation process of the first volute sealing gasket 203, the pulling force will be buffered, thereby making it less likely for dislocation and sliding to occur between the upper positioning frame 2 and the lower positioning frame 3, ensuring that the upper positioning frame 2 and the lower positioning frame 3 are in contact with the user's face during the opening of the mouth. The stability of the structure between the upper positioning frame 2 and the lower positioning frame 3 ensures the sealing effect of the top and bottom of the mask. It is worth mentioning that the reason why the first volute sealing gasket 203 is installed on the top of the upper positioning frame 2 is that when the user opens his mouth, the top of the upper positioning frame 2 will be subjected to the pulling force first. Installing the first volute sealing gasket 203 on the top of the upper positioning frame 2 can buffer the pulling force in the first time, thereby ensuring the stability of the upper positioning frame 2. Compared with the traditional breathing training mask, the breathing training mask provided by the present application does not have a hollow structure between the upper positioning frame 2 and the lower positioning frame 3. The two are connected together by the upper frame 4 and the lower fixed fit. This arrangement makes the upper positioning frame 2 and the lower positioning frame 3 not a separate independent structure.Under the connection between the upper frame 4 and the lower frame 5, a whole support system is formed between the upper positioning frame 2 and the lower positioning frame 3. This support system can provide all-round support and limit the main body 1 of the mask. The upper frame 4 and the lower frame 5 are both arc-shaped structures. When the two are clamped together, there will be a contour protruding toward the outside of the user's face at the connection position between the two. Arc-shaped cushions 6 are provided on the inner walls of the upper frame 4 and the lower frame 5. The size and thickness of the arc-shaped cushions 6 gradually decrease from the connection position of the upper frame 4 and the lower frame 5 to the two ends. The size and thickness of the arc-shaped cushions 6 at the connection position of the upper frame 4 and the lower frame 5 are the largest. When the user opens his mouth, the user's lower jaw will open and drive the lower positioning frame 3 to move. At this time The lower positioning frame 3 will pull the lower frame 5, and the lower frame 5 will pull the upper frame 4 after being subjected to tension. At this time, the upper positioning frame 2 will also receive tension from the upper frame 4. When tension is generated between the upper frame 4 and the lower frame 5, the arc-shaped structures of the two will deform. During the deformation process, the raised contour at the connection position of the upper frame 4 and the lower frame 5 will shrink toward the user's face. At the same time, the arc-shaped cushion 6 located at this position will also move toward the user's face. During the movement, the arc-shaped cushion 6 will contact the user's face and improve the sealing between the mask and the user's face with the help of the squeezing force of the arc-shaped cushion 6. This arrangement ensures the sealing of both sides of the mask when the user opens his mouth to speak or breathe, thereby improving the safety and training effect of the entire training process.
