[0003] The oxygen inhalation time in a pressurized air oxygen chamber is usually 60 to 90 minutes. During the oxygen inhalation process, the input oxygen and the exhaust waste oxygen cannot leak into the oxygen chamber. The oxygen concentration in the oxygen chamber is required to be controlled within 25% throughout the process. The oxygen inhalation devices of the pressurized air oxygen chamber are commonly used earphone-type oxygen inhalation and nasal tube-type oxygen inhalation. The input oxygen and the exhaust waste oxygen are discharged into the cabin, and the oxygen concentration cannot be controlled within a safe range. To strictly control the oxygen concentration, masks, hoods, etc. must be used, but the user experience is not very good. The existing oxygen inhalation and exhaust devices of the pressurized air oxygen chamber will have the following technical problems when in use:

[0004] Existing oxygen supply and exhaust systems incorporate mechanical oxygen input structures or oxygen storage bags, resulting in significant resistance to oxygen inhalation and requiring breaks after a certain period of use. The exhaust flow rate must be manually adjusted by adjusting valves, resulting in low exhaust efficiency and complex operation. Relying on cabin pressure to exhaust oxygen, it cannot effectively discharge oxygen when the chamber pressure is low, failing to ensure full oxygen inhalation and exhaust, and oxygen concentrations can easily exceed standards. The oxygen supply and exhaust system is complex in structure, prone to water accumulation in the pipes, difficult to clean and disinfect, and lacks reliability. Utility Model Content

DETAILED DESCRIPTION

[0036] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0037] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the combination or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention. In addition, in the description of the embodiments of the present invention, the device positional relationships such as "up", "down", "front", "back", "left", "right" and the like in all the drawings are based on the directions or positional relationships shown in the accompanying drawings. Figure 1 As standard.

[0038] like Figure 1As shown, the hyperbaric oxygen chamber oxygen mask with automatic oxygen storage and waste oxygen discharge has a mask assembly 100, which includes a breathing mask 101 and a three-way one-way valve 104 connected thereto, and an oxygen suction pipe 102 and a waste gas discharge pipe 103 respectively connected to the three-way one-way valve 104; the oxygen mask also includes: a storage assembly 200, the storage assembly 200 is connected to the oxygen storage device 240 and the exhaust storage device 250 through the oxygen pipe socket 210 and the exhaust pipe socket 220 respectively; and an exhaust control assembly 300, the exhaust control assembly 300 is respectively connected to the oxygen storage device 240 and the exhaust storage device 250 to control their switching states; wherein: the oxygen storage device 240 and the exhaust storage device 250 respectively have an oxygen storage pipe balance port 241 and an exhaust storage pipe balance port 251 placed at the highest position of the oxygen mask. Figure 4 As shown, in a specific implementation process, one end of the exhaust pipe 103 is inserted into the exhaust pipe socket 220 of the storage assembly 200, and the waste oxygen in the breathing mask 101 can only enter the exhaust storage pipe 256 in one direction through the three-way one-way valve 104 and the exhaust pipe 103.

[0039] The oxygen mask of the present invention controls the oxygen storage device 240 and the exhaust storage device 250 through the emptying component 300 to adjust the oxygen supply concentration in the breathing mask 101 so as to keep meeting the oxygen concentration requirement in the hyperbaric oxygen chamber. When the oxygen chamber pressure in the hyperbaric oxygen chamber is low, negative pressure supply can be performed to achieve effective oxygen discharge, ensuring oxygen inhalation and discharge throughout the hyperbaric oxygen chamber, maintaining the oxygen concentration in the hyperbaric oxygen chamber in compliance with predetermined requirements, and thus ensuring the oxygen supply accuracy requirements in the hyperbaric oxygen chamber and improving user comfort.

[0040] In at least one embodiment, Figure 5 As shown, the oxygen storage device 240 also includes an oxygen tube bend 242 and an oxygen input and drain connector 243 which are sequentially connected to the oxygen tube socket 210. The oxygen tube bend 242 is also connected to the oxygen storage tube 246. The oxygen input and drain connector 243 is respectively connected to the oxygen drain pipe 244 and the oxygen input tube 245. The end of the oxygen storage tube 246 is connected to the oxygen storage tube balance port 241. The oxygen tube bend 242 is placed at the lowest position of the mask assembly 100 and the storage assembly 200, and the oxygen storage tube balance port 241 is set at the highest position. The high specific gravity of oxygen is utilized to facilitate the sinking of oxygen and reduce the leakage of oxygen from the oxygen storage tube balance port.

[0041] In at least one embodiment, Figure 5As can be seen in the figure, the exhaust storage device 250 also includes an exhaust pipe elbow 252 and an exhaust drainage connector 253, which are sequentially connected to the exhaust pipe socket 220. The exhaust pipe elbow 252 is connected to the exhaust storage pipe 256 and the exhaust storage pipe balancing port 251, respectively. The exhaust drainage connector 253 is connected to the quantitative exhaust pipe 254 and the pressure-reducing exhaust pipe 255, respectively. This exhaust storage device 250 allows the exhaust gas discharged during exhalation to pass through the breathing mask 101 and the pressure-reducing exhaust pipe 255, and then enter the exhaust storage pipe 256 for storage. The air in the exhaust storage pipe 256 is replaced by the pressure-reducing exhaust pipe 251. The exhaust drainage connector 253 is located at the lower end of the exhaust pipe elbow 252. The quantitative exhaust pipe 254 at one end of the exhaust drainage connector 253 is used to quantitatively discharge the exhaust gas and moisture from the exhaust storage pipe. The other end of the exhaust drainage connector 253 is connected to the pressure-reducing exhaust pipe 255. When the oxygen chamber enters the pressure-reducing state and the pressure-reducing valve opens, the exhaust gas in the exhaust storage pipe 205 is discharged, increasing the amount of waste oxygen discharged. The capacity of the exhaust storage tube 256 is at least 50% greater than the volume of a single inhaled breath, preventing waste oxygen from leaking through the exhaust storage tube balancing port when oxygen and air are exchanged. Furthermore, the exhaust tube elbow 252 is positioned at the lowest point within the mask assembly 100 and storage assembly 200, while the exhaust storage tube balancing port 251 is also positioned at the highest point. This, again leveraging the high specific gravity of oxygen, facilitates oxygen sinking and reduces waste oxygen leakage from the exhaust storage tube balancing port 251.

[0042] In at least one embodiment, Figure 4 As shown, the storage component 200 also includes an oxygen terminal 260 connected to the discharge control component 300, and the oxygen terminal 260 is connected in sequence to the pressurized oxygen pipe 270, the humidification pot terminal 280 and the humidification pot 290. The humidification pot 290 is also connected in sequence to the oxygen input pipe 245, the oxygen input drainage connector 243 and the oxygen storage pipe 246. By adjusting the flow of the humidification pot 290, the oxygen flow input to the oxygen storage pipe 245 can be controlled, thereby controlling the inhaled oxygen concentration.

[0043] In at least one embodiment, see Figure 4 as well as Figure 6 The exhaust control assembly 300 further comprises a control circuit board 301, and an exhaust control solenoid valve 304, an exhaust throttle valve 305 and an oxygen drain solenoid valve 310 connected to the control circuit board 301, wherein:

[0044] The exhaust control solenoid valve 304 is connected to the quantitative exhaust pipe 254 to quantitatively discharge the exhaust gas in the exhaust storage pipe 256;

[0045] The exhaust throttle valve 305 is connected to the negative pressure end of the negative pressure vacuum generator 308 to obtain negative pressure;

[0046] The oxygen drainage solenoid valve 310 is connected to the oxygen drainage pipe 244 to drain water regularly.

[0047] In at least one embodiment, the input end of the negative pressure vacuum generator 308 is connected to the high pressure air terminal 306 through the exhaust control solenoid valve 307 to obtain high pressure air.

[0048] In at least one embodiment, Figure 4 as well as Figure 6 As shown in FIG, the exhaust end of the negative pressure vacuum generator 308 is discharged into the exhaust muffler 309.

[0049] In the specific implementation process, the overall installation of the breathing mask 101 is shown in FIG. Figure 2 and Figure 3 As shown in the figure, the pressure in the oxygen chamber is divided into three stages: pressure increase, constant pressure and pressure reduction:

[0050] During the initial stage of pressurization, when the chamber pressure gradually rises from ambient pressure to the set pressure, or during the final stage of depressurization, when the chamber pressure gradually drops from the set pressure to ambient pressure, the volume of waste oxygen discharged from exhaust storage tube 256 through metered exhaust pipe 254 will be less than the exhaled volume due to the low chamber pressure. At this point, control circuit board 301 controls the opening of exhaust control solenoid valve 307, allowing high-pressure air to be input to the input port of negative pressure vacuum generator 308. This generates negative pressure at the negative pressure port of negative pressure vacuum generator 308, increasing the flow rate of waste oxygen drawn from exhaust storage tube 256 by metered exhaust pipe 254, resulting in a greater exhaust volume than the exhaled volume.

[0051] When the pressure in the oxygen chamber exceeds the set pressure, control circuit board 301 controls the closing of exhaust control solenoid valve 307. Exhaust oxygen in exhaust storage pipe 256, utilizing the chamber's pressure, flows through metered exhaust pipe 254 to exhaust pressure regulating valve 304 for pressure stabilization. The flow rate is then regulated by exhaust throttle valve 305, and finally discharged through the exhaust port of negative pressure vacuum generator 308 into exhaust muffler 309. In the stable pressure state, the gas flow rate from metered exhaust pipe 254 is set to be no less than 15 liters / minute.

[0052] In at least one embodiment, an external cleaning device is connected to the oxygen storage tube balance port 241 or the exhaust storage tube balance port 251, and a cleaning pipe is used to connect the oxygen tube socket 210 and the oxygen storage tube balance port 241, or to connect the exhaust tube socket 220 and the exhaust storage tube balance port 251, respectively. The oxygen storage tube 245 and the exhaust storage tube 256 can be cleaned and disinfected with liquid to ensure cleanliness and hygiene.

[0053] In at least one embodiment, the exhaust control assembly 300 further includes an assembly mounting shell 303 for mounting, so as to fix the components within the exhaust control assembly 300 together for easy installation and maintenance.

[0054] In at least one embodiment, see Figure 4 and Figure 5 As shown, the storage assembly 200 also has a mask plug mounting plate 230 for mounting the oxygen tube socket 210 and the exhaust tube socket 220 so as to facilitate overall installation and convenient fixation in the hyperbaric oxygen chamber.

[0055] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
