Description

Technical Field

[0001] This utility model relates to the field of ventilation therapy technology, and in particular to a buckle assembly for a breathing mask and a breathing mask. Background Technology

[0002] The headband of a breathing mask secures the frame and padding to the patient's face, ensuring close contact between the padding and the face to provide ventilation. For ease of detachment, the headband and frame are typically connected via a snap-fit ​​mechanism. This snap-fit ​​connection works by deforming the locking mechanism, temporarily enlarging the opening to facilitate insertion of the mating structure. To ensure safety, the force required to deform the locking mechanism is usually quite large. Therefore, the operator needs to apply considerable force to connect and disconnect the mask, making the assembly and disassembly of the headband and frame relatively inconvenient. Utility Model Content

[0006] In one embodiment, the first connecting portion is located between the first support member and the second support member;

[0007] When the elastic element is in the first state, the first support and the second support move or rotate relative to each other, causing the first mating part to move or rotate to a position separated from the first connecting part;

[0008] When the elastic member is in the second state, the first support member and the second support member move or rotate in opposite directions relative to each other, so that the first mating part moves or rotates in opposite directions to the position where it is connected to the first connecting part.

The connecting post passes through the second support member, and the elastic member is sleeved on the connecting post and located between the fastening part and the second support member.

[0010] When the elastic element is in the first state, the connecting post and the first support member move relative to the second support member, causing the first mating part to move to a position separated from the first connecting part; when the elastic element is in the second state, the connecting post and the first support member move in the opposite direction relative to the second support member, causing the first mating part to move in the opposite direction to a position connected to the first connecting part.

[0011] In one embodiment, the second connector further includes a protrusion, which is arranged side by side with the first mating part on the first support member, and the connecting post is connected to the first support member through the protrusion;

[0015] The elastic element is sleeved on the connecting post and located between the second support and the first support;

[0016] When the elastic member is in the first state, the second support member rotates relative to the first support member, causing the first mating part to rotate to a position separated from the first connecting part; when the elastic member is in the second state, the second support member rotates in the opposite direction relative to the first support member, causing the first mating part to rotate in the opposite direction to a position connected to the first connecting part.

[0017] In one embodiment, the first support member is provided with a rotating bracket, and the second support member is provided with a rotating shaft. The rotating shaft is rotatably connected to the rotating bracket. The first mating part and the elastic member are respectively located on both sides of the rotating shaft. The second support member and the first mating part can rotate or rotate in the opposite direction about the rotating shaft.

[0018] In one embodiment, the second support member further includes a connecting plate and a pressing plate located on both sides of the rotating shaft, the first mating part being connected to the connecting plate, and the connecting column penetrating the pressing plate;

[0019] When the elastic element is in the first state, there is a gap between the pressing plate and the fastening part; when the elastic element is in the second state, the pressing plate abuts against the fastening part.

[0020] In one embodiment, the second support member further includes a V-shaped plate, the top two ends of which are connected to the connecting plate and the pressing plate, respectively, and the pivot is located at the bottom of the V-shaped plate.

Therefore, the buckle assembly of the breathing mask of this utility model, when applied to a breathing mask, does not require the use of components that rely on deformation force for locking, but achieves separation and connection through the characteristics of the elastic element. Therefore, no deformation force needs to be overcome during installation and disassembly, thus enabling quick, easy, and effortless installation and disassembly of the breathing mask's headband and frame, making it more convenient for the operator to use.

[0077] The present invention will be further described below with reference to the accompanying drawings.

[0078] like Figure 1As shown, in existing breathing masks, the headband and frame are generally connected using a hook-and-loop fastener. The fastener 301 on the headband has a fastener opening 3011, the size of which (e.g., diameter) is larger than the size (e.g., diameter) of the protruding post 302 on the frame. A protruding structure 3012 is provided on the inner wall of the fastener opening 3011, making the size of the fastener opening 3011 at the position of the protruding structure 3012 smaller than the size of the post 302 on the frame. This allows the fastener to be fixed to the frame and prevents it from detaching. When the fastener needs to be connected to the frame, the force generated by the deformation of the fastener opening 3011 must be overcome to connect the fastener 301 to the post 302; similarly, when the fastener needs to be detached from the frame, the force generated by the deformation of the fastener opening 3011 must be overcome to detach the fastener 301 from the post 302. Therefore, a certain amount of force is required for both connection and disassembly, making the assembly and disassembly of the headband and frame relatively laborious.

[0079] Example 1

[0080] This invention provides a buckle assembly for a breathing mask, which allows for convenient, quick, and easy connection and disconnection of the headband and frame of the breathing mask. Users can easily connect or disconnect the headband from the frame.

[0081] like Figures 1-10 As shown, the buckle assembly for a breathing mask of this invention includes a first connector 310 for connecting to the frame 30 of the breathing mask 3 and a second connector 340 for connecting to the headband 35 of the breathing mask 3. The first connector 310 can be constructed separately from the frame 30 or integrally with the frame 30; that is, the first connector 310 can be a separate component connected to the frame 30, or it can be integrated with the frame 30 as a whole. The second connector 340 can be connected to the end of the headband 35.

[0082] The first connector 310 is provided with a first connecting portion 316, and the second connector 340 is provided with a first mating portion 3413 and an elastic member 3430, with the elastic member 3430 located on one side of the first mating portion 3413. When the elastic member 3430 is in a first state, the first mating portion 3413 is separated from the first connecting portion 316; when the elastic member 3430 is in a second state, the first mating portion 3413 is connected to the first connecting portion 316.

[0083] The elastic element 3430 can be, for example, a spring, wherein the spring can be a compression spring, the first state of which can be a compressed state and the second state of which can be a stretched state. Alternatively, the spring can also be a tension spring, the first state of which can be a stretched state and the second state of which can be a compressed state.

[0084] In addition, the elastic element 3430 can also be a component made of silicone, rubber, or other materials that can undergo elastic deformation.

[0085] The following explanation uses a compression spring as an example.

[0086] like Figure 3 and Figure 4 As shown, the second connector 340 includes a first support member 3410 and a second support member 3420. The first support member 3410 and the second support member 3420 are connected by an elastic member 3430. The first connecting part 316 is located between the first support member 3410 and the second support member 3420. The first mating part 3413 is disposed on the first support member 3410 and / or the second support member 3420.

[0087] When the elastic member 3430 is in the first state, the first support member 3410 and the second support member 3420 can move or rotate relative to each other, so that the first mating part 3413 moves or rotates to a position separated from the first connecting part 316; when the elastic member 3430 is in the second state, the first support member 3410 and the second support member 3420 can move or rotate relative to each other in opposite directions, so that the first mating part 3413 moves or rotates in opposite directions to a position connected to the first connecting part 316.

[0088] Specifically, in this embodiment 1, as Figure 4 As shown, the first support member 3410 and the second support member 3420 can both be constructed as plate-shaped members, and are arranged opposite to each other. The elastic deformation direction of the elastic member 3430 is from one of the first support member 3410 and the second support member 3420 toward the other, for example, the axial direction of the connecting columns 3414 and 3427 described below.

[0089] The first mating part 3413 may be a mating post protruding from the first support member 3410; correspondingly, the first connecting part 316 may be a connecting hole on the first connecting member 310, and the mating post may be inserted into or disengaged from the connecting hole. In this embodiment 1, the mating post may be inserted into the connecting hole from below.

[0090] like Figure 4 As shown, the second connector 340 further includes a connecting post 3414 connected to the first support member 3410 and a fastening portion 3412 connected to the connecting post 3414. The second support member 3420 has a connecting post mounting hole 3422 extending through its thickness direction, and the connecting post 3414 passes through the connecting post mounting hole 3422. An elastic member 3430 is sleeved on the connecting post 3414 and located between the fastening portion 3412 and the second support member 3420.

[0091] like Figure 4As shown, the second connector 340 also includes a protrusion 3411, which is arranged side-by-side with the first mating part 3413 on the first support member 3410. The connecting post 3414 is connected to the first support member 3410 through the protrusion 3411. That is, the fastening part 3412, the connecting post 3414, and the protrusion 3411 are arranged sequentially from top to bottom.

[0092] like Figure 4 and Figure 5 As shown, the diameter of the protrusion 3411 is larger than the diameter of the connecting post 3414 and larger than the diameter of the connecting post mounting hole 3422. Therefore, after the connecting post 3414 passes through the connecting post mounting hole 3422 on the second support member 3420, the second support member 3420 can abut against the end face of the protrusion 3411.

[0093] The fastening part 3412 can be a frustum structure with a diameter larger than that of the connecting post 3414 and larger than that of the connecting post mounting hole 3422. Therefore, the fastening part 3412 can hold the elastic member 3430 between it and the second support member 3420.

[0094] More specifically, one end of the elastic member 3430 abuts against the fastening part 3412, and the other end abuts against the second support member 3420. Therefore, when the elastic member 3430 is in the second state, as... Figure 6 As shown, the elastic member 3430 pushes the second support member 3420 until the second support member 3420 abuts against the end face of the protrusion 3411. Conversely, when the elastic member 3430 is in the first state, as... Figure 7 As shown, the end face of the protrusion 3411 is away from the second support member 3420, that is, there is a gap between the second support member 3420 and the end face of the protrusion 3411.

[0095] Furthermore, when the elastic member 3430 pushes the second support member 3420 against the end face of the protrusion 3411, the first mating part 3413 is inserted into the first connecting part 316. Therefore, the height of the first mating part 3413 is preferably the same as the height of the protrusion 3411, that is, the distance between the end of the first mating part 3413 and the surface of the first support member 3410 is the same as the height of the protrusion 3411 protruding from the surface of the first support member 3410. This ensures that when the second support member 3420 abuts against the end face of the protrusion 3411, the first mating part 3413 is fully inserted into the first connecting part 316, thereby ensuring a stable connection between the first connecting member 310 and the second connecting member 340.

[0096] like Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the elastic element 3430 is in the first state (e.g., Figure 7 When the figure shows the compressed state, the connecting column 3414 and the first support member 3410 move relative to the second support member 3420 (as shown in the figure). Figure 7 (as shown, moving downwards), causing the first mating part 3413 to move (as shown). Figure 7 (As shown, move downwards) to a position where it separates from the first connecting part 316.

[0097] like Figure 5 and Figure 6 As shown, the elastic element 3430 is in the second state (as shown). Figure 5 When the figure shows the stretched state, the connecting column 3414 and the first support member 3410 move in the opposite direction relative to the second support member 3420 (as shown in the figure). Figure 5 (As shown, move upwards), causing the first mating part 3413 to move in the opposite direction (as shown). Figure 5 (As shown, move upwards) to the position where it connects with the first connecting part 316.

[0098] Therefore, it can be seen that when it is necessary to separate the first connector 310 and the second connector 340, the operator can press the latching part 3412 to compress the elastic element 3430, such as... Figure 7 As shown, the connecting post 3414, the protrusion 3411, the first support member 3410, and the first mating part 3413 all move in a direction away from the second support member 3420 until the first mating part 3413 disengages from the first connecting part 316, that is, the first mating part 3413 moves to the position where it is separated from the first connecting part 316; as Figure 9 and Figure 10 As shown, the two can be separated by pulling the first connector 310 and / or the second connector 340.

[0099] When it is necessary to connect the first connector 310 and the second connector 340, the operator can press the fastening part 3412 to compress the elastic element 3430. At this time, there is a gap between the end face of the second support 3420 and the protrusion 3411. The first connecting part 316 can be inserted between the first mating part 3413 on the second support 3420 and the first support 3410 and aligned with the first mating part 3413. After the operator releases the pressing pressure, the elastic element 3430 returns to the stretched state, thereby pushing the fastening part 3412 and causing the connecting post 3414 and the first support 3410 to move in the opposite direction relative to the second support 3420 (e.g., ...). Figure 5As shown, moving upwards, the movement of the first support member 3410 causes the first mating part 3413 to move and insert into the first connecting part 316, i.e., the position connected to the first connecting part 316. Due to the pushing action of the elastic member 3430, the second support member 3420 abuts against the end face of the protrusion 3411. The first connecting member 310 is located below the second support member 3420 and is therefore blocked by the second support member 3420. At the same time, due to the insertion connection of the first mating part 3413 and the first connecting part 316, a stable connection can be formed between the first connecting member 310 and the second connecting member 340.

[0100] In other words, the connection between the first connector 310 and the second connector 340 in this application can be a self-connection method, that is, the automatic insertion connection is achieved under the action of the elastic member 3430's own restoring force, thereby making the connection more convenient.

[0101] In summary, this invention utilizes the compressibility and stretchability of the elastic element 3430. When separating the first connecting member 310 and the second connecting member 340, the two can be easily separated by compressing the elastic element 3430. Correspondingly, when connecting the first connecting member 310 and the second connecting member 340, the restoring force of the elastic element 3430 can easily connect the first mating part 3413 and the first connecting part 316, thereby stably connecting the first connecting member 310 and the second connecting member 340. Therefore, the buckle assembly of this invention, when applied to a breathing mask, eliminates the need for components that engage through deformation force. Instead, separation and connection are achieved through the compression and stretching characteristics of the elastic element 3430. Consequently, no deformation force needs to be overcome during installation and disassembly, enabling quick, easy, and effortless installation and disassembly of the headband 35 and frame 30 of the breathing mask, thus facilitating operation.

[0102] Furthermore, such as Figure 4 As shown, the second support member 3420 (or the first support member 3410) is provided with a headband hole 3421, which passes through the second support member 3420 (or the first support member 3410). The headband 35 of the breathing mask can be fixed to the second support member 3420 (or the first support member 3410) through the headband hole 3421.

[0103] Example 2

[0104] like Figures 11-18 As shown, based on Embodiment 1 above, a modified Embodiment 2 is provided. The following will mainly describe the differences between Embodiment 2 and Embodiment 1 above, while the similarities will not be repeated.

[0105] like Figure 11 and Figure 12As shown, in this embodiment 2, the first mating part 3413 is disposed on the second support member 3420. The second connecting member 340 further includes a connecting post 3414 connected to the first support member 3410 and a fastening part 3412 connected to the connecting post 3414. The second support member 3420 is provided with a connecting post mounting hole 3422 penetrating its thickness direction, and the connecting post 3414 penetrates the connecting post mounting hole 3422. The elastic member 3430 is sleeved on the connecting post 3414 and is located between the second support member 3420 and the first support member 3410.

[0106] When the elastic element 3430 is in the first state, such as Figure 15 , Figure 16 and Figure 17 As shown, the second support member 3420 can rotate relative to the first support member 3410, thereby causing the first mating part 3413 to rotate to a position separated from the first connecting part 316; when the elastic member 3430 is in the second state, such as Figure 13 and Figure 14 As shown, the second support member 3420 can rotate in the opposite direction relative to the first support member 3410, thereby causing the first mating part 3413 to rotate in the opposite direction to a position connected to the first connecting part 316.

[0107] Specifically, such as Figure 12 and Figure 13 As shown, a rotating bracket 3415 is provided on the first support member 3410. The rotating bracket 3415 is located on both sides of the first support member 3410 and is arranged opposite to each other. The rotating bracket 3415 is provided with bracket holes 3416.

[0108] Please continue to participate. Figure 12 and Figure 13 The second support member 3420 is provided with a rotating shaft 3423, which is disposed in the bracket hole 3416, so the rotating shaft 3423 is rotatably connected to the rotating bracket 3415. The first mating part 3413 and the elastic member 3430 are respectively located on both sides of the rotating shaft 3423.

[0109] When the elastic member 3430 is in the first state, the first mating part 3413 can rotate about the rotating shaft 3423 to a position where it is separated from the first connecting part 316; when the elastic member 3430 is in the second state, the first mating part 3413 can rotate in the opposite direction about the rotating shaft 3423 to a position where it is connected to the first connecting part 316.

[0110] Specifically, such as Figure 12As shown, the second support member 3420 includes a connecting plate 3401 and a pressing plate 3402 located on both sides of the rotating shaft 3423, and a V-shaped plate 3403 connected to the connecting plate 3401 and the pressing plate 3402 respectively. The top two ends of the V-shaped plate 3403 are connected to the connecting plate 3401 and the pressing plate 3402 respectively, and the rotating shaft 3423 is located at the bottom of the V-shaped plate 3403.

[0111] like Figure 12 As shown, and please refer to Figure 13 The rotating shaft 3423 passes through the bottom of the V-shaped plate 3403 and is respectively set in the bracket holes 3416 on the rotating brackets 3415 on both sides of the first support member 3410. Therefore, the V-shaped plate 3403 can rotate relative to the first support member 3410 through the rotating shaft 3423.

[0112] The connecting post mounting hole 3422 is located on the pressing plate 3402, and the connecting post 3414 passes through the connecting post mounting hole 3422 to connect with the pressing plate 3402. The fastening part 3412 is located above the pressing plate 3402, and its diameter is larger than the diameter of the connecting post mounting hole 3422, so that the elastic member 3430 can be constrained between the pressing plate 3402 and the first support member 3410.

[0113] The first mating part 3413 is connected to the connecting plate 3401. The first mating part 3413 can be a mating post that protrudes downward from the connecting plate 3401. The difference between this embodiment 2 and the above embodiment 1 is that in the above embodiment 1, the first mating part 3413 is inserted into the first connecting part 316 from top to bottom, while in this embodiment 2, the first mating part 3413 is inserted into the first connecting part 316 from bottom to top.

[0114] like Figure 15 As shown, when the elastic element 3430 is in the first state, there is a gap between the pressing plate 3402 and the fastening part 3412; as Figure 13 As shown, when the elastic member 3430 is in the second state, the pressing plate 3402 abuts against the fastening part 3412.

[0115] Therefore, it can be seen that when it is necessary to separate the first connector 310 and the second connector 340, the operator can press the pressing plate 3402 to compress the elastic element 3430, such as... Figure 15 and Figure 16 As shown, the elastic element 3430 is compressed, causing the V-shaped plate 3403 to rotate relative to the first support member 3410 via the pivot 3423. That is, the connecting plate 3401 rotates relative to the first support member 3410. The rotation and lifting of the connecting plate 3401 causes the first mating part 3413 to separate from the first connecting part 316, i.e., the first mating part 3413 is in a position separated from the first connecting part 316. Figure 17 and Figure 18As shown, the two can be separated by pulling the first connector 310 and / or the second connector 340.

[0116] When it is necessary to connect the first connector 310 and the second connector 340, the operator can press the latching part 3412 to compress the elastic element 3430, and the connecting plate 3401 will be raised accordingly. There is a certain distance between the first mating part 3413 and the first support member 3410, so that the first connector 310 can be placed between the first mating part 3413 and the first support member 3410 and the first connecting part 316 is aligned with the first mating part 3413. After the operator releases the pressing force, the elastic element 3430 returns to the stretched state, thereby pushing the pressing plate 3402 to rotate in the opposite direction relative to the first support member 3410, that is, the pressing plate 3402 rotates and rises. Therefore, the connecting plate 3401 rotates and falls accordingly until the first mating part 3413 is inserted into the first connecting part 316, that is, the position where it is connected to the first connecting part 316. Due to the pushing action of the elastic member 3430, the pressing plate 3402 abuts against the end face of the fastening part 3412. The first connecting member 310 is located below the connecting plate 3401 and is therefore blocked by the connecting plate 3401. At the same time, due to the insertion connection of the first mating part 3413 and the first connecting part 316, a stable connection can be formed between the first connecting member 310 and the second connecting member 340.

[0117] Therefore, unlike Embodiment 1, Embodiment 2 uses a rotating shaft 3423 to form a pivot point. When the pressing plate 3402 is pressed down, the connecting plate 3401 on the other side rises, causing the first mating part 3413 to separate from the first connecting part 316. Correspondingly, when the pressing plate 3402 is lifted by the restoring force of the elastic member 3430, the connecting plate 3401 on the other side falls, connecting the first mating part 3413 to the first connecting part 316. Embodiment 2, by combining the compression and tension characteristics of the elastic member 3430 with the pivot point 3423, makes the connection and separation of the first connecting member 310 and the second connecting member 320 easier and more convenient.

[0118] Example 3

[0119] like Figures 19-27 As shown, based on Embodiments 1 and 2 above, a modified Embodiment 3 is provided. The following will mainly describe the differences between Embodiment 3 and Embodiments 1 and 2 above, while the similarities will not be repeated.

[0120] like Figure 19 and Figure 20As shown, the difference between this embodiment 3 and the above-mentioned embodiments 1 and 2 is that the first support member 3410 and the second support member 3420 in this embodiment 3 both penetrate through the first connecting portion 316.

[0121] Specifically, such as Figure 19 As shown, the first mating part 3413 includes a first latching protrusion 3417 disposed on the first support member 3410 and a second latching protrusion 3426 disposed on the second support member 3420. The first latching protrusion 3417 is a protrusion structure that protrudes outward from the end of the first support member 3410, and its dimension in one direction is larger than the dimension of the first support member 3410. Similarly, the second latching protrusion 3426 is a protrusion structure that protrudes outward from the end of the second support member 3420, and its dimension in one direction is larger than the dimension of the second support member 3420.

[0122] like Figure 19 As shown, the elastic member 3430 is located between the first support member 3410 and the second support member 3420, and the elastic member 3430 is located on one side of the first connecting portion 316, while the first locking protrusion 3417 and the second locking protrusion 3426 are both located on the other side of the first connecting portion.

[0123] When the elastic element 3430 is in the first state, such as Figure 23 , Figure 24 , Figure 25 , Figure 26 and Figure 27 As shown, the first support member 3410 and the first latching protrusion 3417 move relative to the second support member 3420 to a position separated from the first connecting portion 316. In this separated position, the distance between the first latching protrusion 3417 and the second latching protrusion 3426 is less than their mating distance with the first connecting portion 316. For example, when the first connecting portion 316 is configured as a connecting hole, the aforementioned mating distance is the diameter of the connecting hole.

[0124] When the elastic element 3430 is in the second state, such as Figure 21 and Figure 22 As shown, the first support member 3410 and the first locking protrusion 3417 move in the opposite direction to the second support member 3420 to a position connected to the first connecting portion 316. At this connected position, the distance between the first locking protrusion 3417 and the second locking protrusion 3426 is greater than or equal to their engagement distance with the first connecting portion 316, thereby preventing the first support member 3410 and the second support member 3420 from disengaging from the first connecting portion 316.

[0125] Therefore, it can be seen that when the elastic member 3430 is compressed, the first support member 3410 and the first locking protrusion 3417 can move in the direction close to the second support member 3420, thereby reducing the distance between the first support member 3410 and the second support member 3420, that is, reducing the distance between the first locking protrusion 3417 and the second locking protrusion 3426, so that the distance is smaller than the aperture of the first connecting part 316. Therefore, the first support member 3410 and the first locking protrusion 3417, the second support member 3420 and the second locking protrusion 3426 can be disengaged from the first connecting part 316.

[0126] Conversely, when the elastic member 3430 is stretched, the first support member 3410 and the first locking protrusion 3417 can move away from the second support member 3420, thereby increasing the distance between the first support member 3410 and the second support member 3420, that is, increasing the distance between the first locking protrusion 3417 and the second locking protrusion 3426, so that this distance is greater than the aperture of the first connecting part 316. Therefore, through the blocking effect of the first locking protrusion 3417 and the second locking protrusion 3426, the first support member 3410 and the first locking protrusion 3417, the second support member 3420 and the second locking protrusion 3426 cannot be disengaged from the first connecting part 316.

[0127] Furthermore, such as Figure 20 and Figure 22 As shown, the second connector 340 also includes a sleeve 3419 connected to the inner side of the first support 3410 and a connecting post 3427 connected to the inner side of the second support 3420. The connecting post 3427 and the sleeve 3419 are arranged opposite to each other, and the elastic member 3430 is sleeved on the connecting post 3427 and the sleeve 3419. Figure 25 As shown, when the elastic element 3430 is in the first state, that is, the distance between the first support element 3410 and the second support element 3420 decreases, so the connecting post 3427 is inserted into the sleeve 3419; as Figure 22 As shown, when the elastic member 3430 is in the second state, that is, the distance between the first support member 3410 and the second support member 3420 decreases, and the connecting post 3427 extends out of the sleeve 3419.

[0128] Furthermore, for ease of operation, such as Figure 20 As shown, the second connector 340 further includes a first pressing portion 3418 disposed on the first support member 3410 and a second pressing portion 3425 disposed on the second support member 3420. The first pressing portion 3418 and the second pressing portion 3425 are respectively disposed corresponding to the positions of the sleeve 3419 and the connecting post 3427. Figure 22As shown, the first pressing part 3418 can be coaxially arranged with the connecting post 3427, and the second pressing part 3425 can be coaxially arranged with the sleeve 3419, thus facilitating the operator to apply force. The first pressing part 3418 and the second pressing part 3425 can be any structure that facilitates pressing operation, such as a frustum-shaped structure.

[0129] Therefore, it can be seen that when it is necessary to separate the first connector 310 and the second connector 340, such as Figure 23 As shown, the operator can hold the second pressing part 3425 and press the first pressing part 3418, thereby compressing the elastic element 3430, as... Figure 24 and Figure 25 As shown, the connecting post 3427 extends into the sleeve 3419, and the first support member 3410 and the second support member 3420 are close to each other until the distance between the first locking protrusion 3417 and the second locking protrusion 3426 is less than the diameter of the hole in the first connecting part 316. Figure 26 and Figure 27 As shown, the two can be separated by pulling the first connector 310 and / or the second connector 340.

[0130] When it is necessary to connect the first connector 310 and the second connector 340, such as Figure 23 As shown, the operator can hold the second pressing part 3425 and press the first pressing part 3418, thereby compressing the elastic member 3430. The first support member 3410 and the second support member 3420 move closer to each other until the distance between the first latching protrusion 3417 and the second latching protrusion 3426 is less than the diameter of the hole in the first connecting part 316. Then, the first support member 3410, the first latching protrusion 3417, the second support member 3420, and the second latching protrusion 3426 can pass smoothly through the first connecting part 316. Afterwards, the operator releases the pressing force, and the elastic member 3430 returns to the stretched state, thereby pushing the first support member 3410 away from the second support member 3420 until the distance between the first latching protrusion 3417 and the second latching protrusion 3426 is greater than the diameter of the hole in the first connecting part 316. Then, the first support member 3410 and the second support member 3420 cannot be dislodged from the first connecting part 316.

[0131] Furthermore, such as Figure 19 As shown, the end of the second support member 3420 is also provided with a connecting ring, and the connecting ring is provided with a headband hole 3421. The headband hole 3421 and the first mating part 3413 are respectively located on both sides of the elastic member 3430. The headband 35 of the breathing mask can be fixed to the second support member 3420 through the headband hole 3421.

[0132] Understandably, the headband hole 3421 can also be provided on the first support member 3410.

[0133] In addition, such as Figure 19In this structure of embodiment 3, the first connecting member 310 includes an extension plate 311 and a baffle 317. The extension plate 311 is used to connect to the frame 30, or the extension plate 311 may be part of the frame 30. The baffle 317 is disposed on the extension plate 311 and may be disposed perpendicular to the extension plate 311 at an angle. The first connecting portion 316 is a connecting hole formed on the baffle 317.

[0134] In this embodiment 3, when pressing, the operation is performed through the second pressing part 3425 and the first pressing part 3418 respectively. Therefore, the force on each structure is balanced and uniform during disassembly and assembly, which can improve its service life.

[0135] like Figure 2 As shown, this utility model also provides a breathing mask, including a buckle assembly for the breathing mask described in each of the embodiments 1-5 above, and further including a frame 30, a pad, a curved tube 33, and a headband 35. The frame 30 is connected to or integrally formed with the first connecting member 310, and the headband 35 is connected to the second connecting member 340. Through the compression and tension characteristics of the elastic member 3430, the connection and separation between the headband 35 and the frame 30 can be easily achieved in a more effortless manner.

[0136] A liner is positioned inside the frame 30 for a secure seal against the patient's face. A bend 33 is connected to the frame 30 or the liner to deliver positive pressure ventilation gas to the patient. The bend 33 can rotate relative to the frame 30 or the liner, thereby adjusting its relative position to the breathing gas generator to allow for more convenient alignment of the tubing with the patient's position. The bend 33 is connected to the pressure support device 1 via the ventilation tubing 2, allowing positive pressure ventilation gas from the pressure support device 1 to be delivered to the liner for the patient's breathing.

[0137] The breathing mask of this utility model can be a full-face mask, a nose mask, or a mouth and nose mask.

[0138] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
