DETAILED DESCRIPTION
[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0029] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0030] Please refer to Figures 1 to 4 , Figure 1 A schematic diagram of the structure of an oxygen inhalation mask provided in an embodiment of the present application; Figure 2 for Figure 1 A front view of Figure 3 for Figure 1 Rear view of Figure 4 This is a cross-sectional view of the first gas port, the second gas port, and the third gas port provided in an embodiment of the present application.
[0031] Please refer to Figure 1 and Figure 4 The present application provides an oxygen inhalation mask, comprising a mask body 1; the mask body 1 has a first air port 2 and a second air port 3, the first air port 2 and the second air port 3 are respectively provided with a one-way valve 4, the one-way valves 4 of the first air port 2 and the second air port 3 are opened in opposite directions, for example, the one-way valve 4 of the first air port 2 is opened in one direction toward the inner side of the mask body 1, and the one-way valve 4 of the second air port 3 is opened in one direction toward the outer side of the mask body 1; wherein the aforementioned one-way valve 4 may include a baffle 41, a shaft and an elastic valve core assembly, the shaft passes through the mask body 1, the baffle 41 and the elastic valve core assembly are respectively arranged at both ends of the shaft, and the installation spacing of the baffle 41 and the elastic valve core assembly along the shaft is adjustable.
[0032] In this embodiment, the first air port 2 and the second air port 3 can be used as the air inlet and the air outlet of the mask body 1, respectively. For example, the first air port 2 is provided with a one-way valve 4, and the one-way valve 4 is opened one-way toward the inside of the mask body 1, then the first air port 2 can be regarded as the air inlet of the mask body 1, and when the oxygen mask is used, the first air port 2 can be connected to an external device such as an oxygen supply instrument; at the same time, the second air port 3 is provided with a one-way valve 4, and the one-way valve 4 is opened one-way toward the outside of the mask body 1, then the second air port 3 can be regarded as the air outlet of the mask body 1, and when the oxygen mask is used, the second air port 3 is often directly to the air, and of course, it can also be connected to other devices according to specific usage requirements.
[0033] In this embodiment, both the first air port 2 and the second air port 3 are provided with a one-way valve 4, the shaft of the one-way valve 4 passes through the mask body 1, and the baffle 41 and the elastic valve core assembly of the one-way valve 4 are respectively located on the inner and outer sides of the mask body 1. Taking the first air port 2 and its one-way valve 4 as an example, the baffle 41 combined with the mask body 1 can limit the air flow through the first air port 2, and the elastic valve core assembly can adjust the fit between the baffle 41 and the mask body 1, so that the baffle 41 opens in a single direction, and at the same time, the baffle 41 blocks the gas from flowing through the first air port 2 in the opposite direction. In the aforementioned one-way valve 4, the installation spacing of the baffle 41 and the elastic valve core assembly along the shaft is adjustable, which allows the operator to adjust the opening pressure of the one-way valve 4, which is conducive to adapting the mask body 1 to different wearers.
[0034] In order to make the installation spacing of the baffle 41 and the elastic valve core assembly along the shaft rod adjustable, in this embodiment, one of the baffle 41 and the elastic valve core assembly can be movably connected to the shaft rod, for example, the baffle 41 is fixed to one end of the shaft rod, and the elastic valve core assembly is spirally connected to the other end of the shaft rod. In addition, both the baffle 41 and the elastic valve core assembly can be movably connected to the shaft rod to facilitate adjustment by the operator. For example, for the one-way valve 4 of the first air port 2, the baffle 41 of the one-way valve 4 is located on the outside of the mask body 1, and the elastic valve core assembly of the one-way valve 4 is located on the inside of the mask body 1. The operator can adjust the baffle 41 of the one-way valve 4 along the valve stem to change the distance between the baffle 41 and the elastic valve core assembly. Conversely, for the one-way valve 4 of the second air port 3, the baffle 41 of the one-way valve 4 is located on the inside of the mask body 1, and the elastic valve core assembly of the one-way valve 4 is located on the outside of the mask body 1. The operator can adjust the elastic valve core assembly of the one-way valve 4 along the valve stem to change the distance between the baffle 41 and the elastic valve core assembly.
[0035] In summary, the oxygen mask provided by the present application provides different air flow channels for the inhalation process and the exhalation process, respectively, to ensure that oxygen flows from the first air port 2 into the inner side of the mask body 1 in one direction during the inhalation process, and to ensure that the gas inside the mask body 1 flows out of the mask body 1 from the second air port 3 in one direction during the exhalation process. In short, the first air port 2 is opened and the second air port 3 is closed during the inhalation process, and the second air port 3 is opened and the first air port 2 is closed during the exhalation process. The above measures can not only eliminate the need for exhaust from the side of the mask body 1, effectively prevent external bacteria from entering the mask body 1, which is conducive to improving the use effect of the oxygen mask, and is conducive to improving the wearing connection effect of the mask body 1 and the wearer; the above measures can also improve the maintenance characteristics of the oxygen mask, for example, the operator can quickly replace or clean the one-way valve 4 of the first air port 2 and the second air port 3, and can clean different parts separately after disassembling the one-way valve 4 and other parts of the oxygen mask, so as to achieve graded disinfection and sterilization of different parts, and achieve efficient and dead-angle disinfection of the oxygen mask.
[0036] The oxygen mask provided by the present application is further described below in conjunction with the accompanying drawings and implementation examples.
[0037] For reference Figures 1 to 4 In some embodiments, the one-way valve 4 may include a baffle 41, a shaft and an elastic valve core assembly, and the elastic valve core assembly includes a rigid valve core cap 42 and an elastic body; in this embodiment, the elastic body is sleeved with the shaft, and the elastic body and the rigid valve core cap 42 are located on the same side of the mask body 1, and the two ends of the elastic body press the valve core cap and the mask body 1 respectively, and the valve core cap and the mask body 1 apply pressure to the two ends of the elastic body. The elastic body can be specifically set as a spring.
[0038] In the above embodiment, the elastic body and the rigid valve core cap 42 can make the baffle 41 close to the mask body 1, so as to close the first air port 2 and the second air port 3. When the external device such as the oxygen supply instrument connected to the first air port 2 is turned on, the gas provided by the oxygen supply instrument applies pressure to the first air port 2 and the elastic body, compresses the elastic body, and then the baffle 41 is separated from the mask body 1, thereby opening the first air port 2; obviously, the aforementioned elastic body and baffle 41 are both parts of the one-way valve 4 provided at the first air port 2. When the gas inside the mask body 1 continues to accumulate and the air pressure continues to increase, the gas inside the mask body 1 applies pressure to the second air port 3 and the elastic body, compresses the elastic body, and then the baffle 41 is separated from the mask body 1, thereby opening the second air port 3; obviously, the aforementioned elastic body and baffle 41 are both parts of the one-way valve 4 provided at the second air port 3.
[0039] On the basis of the above embodiments, in order to facilitate the operator to adjust the opening pressure of the two one-way valves 4 from the outside of the mask body 1, specifically: the rigid valve core cap 42 of the one-way valve 4 of the first air port 2 is movably mounted on the shaft rod, and the operator can adjust the aforementioned rigid valve core cap 42 from the outside of the mask body 1; the baffle 41 of the second air port 3 is movably mounted on the shaft rod, and the operator can adjust the aforementioned baffle 41 from the outside of the mask body 1.
[0040] Please refer to 2 to Figure 4 In some embodiments, the first air port 2 and the second air port 3 both include a mounting ring 10 and ribs 20 radially distributed around the mounting ring 10. Taking the first air port 2 as an example, the valve stem of the one-way valve 4 is inserted into the mounting ring 10 of the first air port 2, and the baffle 41 and the elastic valve core assembly of the one-way valve 4 are respectively located at the axial ends of the aforementioned mounting ring 10, and the aforementioned baffle 41 is attached to the mounting ring 10 and the ribs 20 around it. When the one-way valve 4 of the first air port 2 is opened unidirectionally toward the inside of the mask body 1, the baffle 41 is separated from the mounting ring 10 and the ribs 20 around it, and the gas can flow from the gap between the adjacent ribs 20 to the inside of the mask body 1.
[0041] In addition, please refer to Figure 1 and Figure 4 In some embodiments, the mask body 1 has a third air port 5, and the third air port 5 is provided with an anti-suffocation valve 6 to improve the safety of the oxygen mask.
[0042] The third air port 5 may include a mounting shell 51 and a vent hole 52, and the anti-suffocation valve 6 may be detachably connected to the mounting shell 51. The operator may choose whether to install the anti-suffocation valve 6 according to specific needs. Of course, if the operator chooses not to install the anti-suffocation valve 6, the third air port 5 needs to be blocked to ensure the closedness of the space inside the mask body 1.
[0043] On the basis of the above-mentioned embodiments, the oxygen inhalation mask provided by the present application further includes a functional block; the aforementioned functional block may include one or more of a blocking block, a detection block, and a dehumidification block, any one of which may be detachably connected to the mounting shell 51, and the operator may assemble each functional block to the mounting shell 51 according to specific needs. For example, if the operator chooses not to install the anti-suffocation valve 6, the blocking block may be assembled to the mounting shell 51 of the third air port 5, and the third air port 5 may be closed by the blocking block to prevent the gas inside and outside the mask body 1 from flowing from the third air port 5. For another example, if the operator chooses not to install the anti-suffocation valve 6, the detection block may be assembled to the mounting shell 51 of the third air port 5, and the detection element of the detection block may be used to obtain the environmental parameters of the inner side of the mask body 1 in real time, for example, the concentration of carbon dioxide inside the mask body 1 may be detected by the detection element of the detection block. Similarly, if the operator chooses not to install the anti-suffocation valve 6, the dehumidification block can be installed on the installation shell 51 of the third air port 5, and the dehumidification block can be used to dehumidify the inner space of the mask body 1 to improve the use effect and user experience of the oxygen mask.
[0044] For reference Figures 1 to 3 In some embodiments provided above, the mask body 1 may include a bottom shell 11 and a center shell 12; the center shell 12 is disposed in the middle of the bottom shell 11, and the center shell 12 protrudes outward relative to the bottom shell 11; in this embodiment, the first air port 2, the second air port 3, and the third air port 5 are all disposed in the center shell 12. The center shell 12 protrudes toward the outside of the mask body 1 relative to the bottom shell 11, and correspondingly, the bottom shell 11 sinks toward the inside of the mask body 1 relative to the center shell 12; the center shell 12 protrudes outward relative to the bottom shell 11, which is conducive to forming sufficient space near the mouth and nose of the user of the mask body 1, and the bottom shell 11 sinks inward relative to the center shell 12, which is conducive to the edge of the mask body 1 being more stably and reliably attached to the face of the user, and is also conducive to improving the fitting effect between the edge of the mask body 1 and the face of the user.
[0045] For reference Figure 1 In some of the embodiments provided above, a detection hole 7 and a mounting column 8 are provided on the edge of the bottom shell 11; the aforementioned detection hole 7 has a self-sealing function, and when no foreign object is inserted into the detection hole 7, the detection hole 7 is in a closed state; the aforementioned mounting column 8 is provided on the edge of the bottom shell 11, for example, a plurality of mounting columns 8 can be dispersed around the central shell 12 on the bottom shell 11, and these mounting columns 8 can be used for tying straps, so that the user can wear the oxygen mask with the straps.
[0046] In addition, please refer to Figure 1 , Figure 3 and Figure 4In some embodiments, the mask body may include a rigid cover shell and an airbag 13; wherein the airbag 13 is located on the inner side of the rigid cover shell, and the airbag 13 is distributed along the cover shell edge of the rigid cover shell. When wearing the oxygen mask, the airbag 13 fits the user's face, which can ensure the fit effect between the mask body 1 and the user's face, and improve the wearing comfort of the mask body 1 on the user's face. wherein, the rigid cover shell may include the bottom shell 11 and the center shell 12 mentioned in some embodiments above.
[0047] In the above embodiment, the edge of the rigid cover can be provided with an airbag slot, and the airbag 13 can be sealed and embedded in the airbag slot. It can be seen that in the oxygen breathing mask, the airbag 13 can be detachably installed in the airbag slot. In addition, the airbag 13 is provided with an airbag inflation port 131, which can be used to inflate and deflate the airbag 13.
[0048] The oxygen mask provided by the present application is introduced in detail above. Specific examples are used herein to illustrate the principle and implementation method of the present application. The description of the above embodiments is only used to help understand the method and core idea of the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
