Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0037] The present invention is described in further detail below with reference to the accompanying drawings:

[0038] A pressure maintenance system for an oxygen chamber 6, such as Figure 1-6 As shown, it includes an oxygen production component 2, which includes a cold dryer 23, an oxygen production molecular sieve 24, an oxygen gas storage tank 27 and a third gas valve 26; the output end of the cold dryer 23 is connected to the third gas valve 26 and the oxygen production molecular sieve 24 respectively; the output end of the oxygen production molecular sieve 24 is connected to the oxygen gas storage tank 27; and the third gas valve 26 is connected to the oxygen cabin 6.

[0039] On the one hand, the gas output by the cold dryer enters the oxygen chamber 6 through the third gas valve to pressurize the oxygen chamber; on the other hand, oxygen is prepared by the oxygen molecular sieve 24 and stored in the oxygen storage tank 27. After reaching a certain pressure, oxygen is supplied to the oxygen chamber; thereby improving the initialization efficiency of the oxygen chamber, reducing the user's waiting time, and improving the user experience.

[0040] The oxygen chamber is also equipped with a second temperature sensor and a pressure sensor, and the opening of the third air valve should be coordinated with the detection value of the pressure sensor. The output end of the cold dryer 23 is provided with a second three-way connection, which is respectively provided with a third air valve 26 and a fourth air valve 28. The fourth air valve 28 is connected to the oxygen-generating molecular sieve.

[0041] like Figure 6 The oxygen production component 2 also includes an air compressor 22, a first pressure reducing valve 25, an air intake component 3 and a breathing mask 4; the output end of the air compressor 22 is connected to the cold dryer 23; the output end of the oxygen storage tank 27 is connected to the first pressure reducing valve 25; the first pressure reducing valve 25 is connected to the air intake component 3 through the air intake pipe 21, and the air intake component 3 is used to connect the oxygen production component and the breathing mask; the air intake component 3 is connected to the breathing mask 4.

[0042] Figure 1 、 Figure 2 and Figure 3 Also shown is an exhaust assembly 5 arranged in the oxygen chamber 6, which includes an exhaust box 52, a third one-way valve 54 and a second exhaust pipe 55; the exhaust box 52 is connected to the output end of the breathing mask 4 through a first exhaust pipe 51; one end of the second exhaust pipe 55 is connected to the exhaust box 52 and the other end is connected to the outside of the oxygen chamber 6; the third one-way valve 54 is connected to the exhaust box 52; and an exhaust valve 56 is provided on the second exhaust pipe 55.

[0043] The second airbag 53 and the third one-way valve 54 can absorb air flow fluctuations; on the one hand, the third one-way valve 54 can prevent the exhaust valve from closing accidentally and causing difficulty in breathing when the oxygen supply is stopped. On the other hand, when the exhaust volume is large, the pressure in the oxygen chamber is greater than the pressure in the exhaust box, and the exhaust box is compensated, that is, the gas in the oxygen chamber enters the exhaust box through the third one-way valve 54 and is discharged out of the oxygen chamber through the second exhaust pipe.

[0044] Among them, the exhaust box 52 is also connected to a second airbag 53; the exhaust box 52 is connected to the second airbag 53 through a second connecting pipe 531; multiple third one-way valves 54 are distributed at multiple positions of the oxygen chamber 6 to provide buffering for exhaust and avoid airflow jitter or fluctuation.

[0045] When the exhaust valve 56 is open, the opening control of the exhaust valve requires adjustment of data such as airflow and air pressure. Therefore, the control of the exhaust valve 56 has a certain lag. The second airbag 53 and the third one-way valve 54 can well absorb the airflow fluctuations during the lag time.

[0046] A heating wire 511 and a temperature sensor 512 are provided in the first exhaust pipe 51 .

[0047] The air intake assembly 3 includes an air intake box 31 and a one-way valve 36, the one-way valve 36 includes a second one-way valve 38, one end of the air intake box 31 is connected to the output end of the oxygen production assembly 2; the other end of the air intake box 31 is connected to the input end of the breathing mask 4, and the second one-way valve 38 is connected to the input end of the breathing mask 4 through the second air valve 35.

[0048] The air intake assembly provides oxygen to the breathing mask through the air intake box; the buffer passage switch of the second one-way valve is controlled by the second air valve 35; when the buffer passage is opened, the second one-way valve can supply air to the oxygen mask in one direction, avoiding difficulty in breathing when there is no oxygen supply.

[0049] The second gas valve may be a normally open solenoid valve, which keeps the buffer passage unobstructed in the event of a power outage.

[0050] The air inlet box 31 is sequentially connected to the first air valve 33, the first three-way connection 39, and the breathing mask 4. The second air valve 35 is connected to the first three-way connection 39. The air inlet box 31 is also connected to a first one-way valve 37. The second air valve 35 controls whether oxygen is supplied to the breathing mask 4. The first one-way valve 37 provides a buffer for the air inlet box 31. A first air bag 32 is connected to the air inlet box 31 to control the fluid pressure within the breathing mask 4.

[0051] Figure 1 A seat 61 is shown inside the oxygen chamber 6 for use by a user. An installation cavity 63 is provided below an armrest 62 of the seat 61. The first airbag 32 is installed within the installation cavity 63. More specifically, two first airbags 32 are installed within the installation cavity 63 below the left and right armrests 62, respectively, further increasing the cushioning capacity.

[0052] like Figure 3 One end of the second air valve 35 is provided with a return air pipe 351. One side of the return air pipe 351 is mounted on the side of the seat back 64 of the seat 61 via a mounting member 65. The second one-way valve 38 is mounted on the outer end of the return air pipe 351. Mounting the second one-way valve on the side of the seat back can reduce the risk of the second one-way valve being blocked.

[0053] The first three-way connection 39 is connected to the breathing mask 4 via an air supply pipe 42. A flow meter 41 is provided on one side of the air supply pipe 42 to monitor respiratory flow. The middle portion of the air supply pipe 42 is mounted on the side of the chair back 64 via another mounting member 65. The oxygen generator 2 is connected to the air inlet box 31 via an air inlet pipe 21.

[0054] The air intake box 31 can realize multi-port connection, and can be connected to the one-way valve, the air intake pipe 21, the air intake box 31, the air bag, etc. at the same time. Figure 3 A cover on one side of the air intake box is hidden in the housing and is used to seal the opening of the air intake box.

[0055] Figure 5 The control component 7 of the present invention is shown, and the control component 7 is respectively connected to the exhaust valve 56, the oxygen production component 2, the second air valve 35, the third air valve 26, the first pressure reducing valve 25, the cold dryer 23, the molecular sieve 24, the air compressor 22, the heating wire 511, the temperature sensor 512, and the second temperature sensor and the pressure sensor provided in the oxygen chamber 6.

[0056] The control component 7 can adopt a microcontroller MCU, a controller CPU or a combination thereof. By detecting the temperature in the first exhaust pipe 51, it controls the opening of the heating wire 511, and heats the first exhaust pipe 51 through the heating wire 511 to avoid condensation of condensed water and prevent bacteria from growing in the first exhaust pipe 51.

[0057] Figure 4 The specific structure of the one-way valve 36 is shown, comprising a tube body 361, a stopper plate 363, and an elastic membrane 367. A handle 362 is provided on the underside of the tube body 361 to facilitate installation of the one-way valve 366 at one end of the trachea. A stopper plate 363 is provided within the tube body 361, with through-holes 364 and mounting holes 365 spaced apart thereon. The elastic membrane 367 is mounted on one side of the stopper plate 363 via a mounting boss 366. The mounting boss 366 extends toward and protrudes from the opening at one end of the tube body 361. That is, the outer end of the mounting boss 366 is higher than the opening, which, to a certain extent, prevents the opening from being completely blocked.

[0058] In the present invention, the third air valve 26 is connected to the interior of the oxygen chamber and is used to maintain a positive pressure within the chamber. For example, after a user enters the chamber and closes the door, the third air valve 26 is used to pressurize the chamber, maintaining it within a set pressure range. This improves pressurization efficiency, reduces waiting time, and enhances the user experience. While pressurizing, the molecular sieve generates oxygen. Once the oxygen pressure reaches the preset pressure range, oxygen is supplied to the air intake assembly 3 via the first pressure reducing valve 25. The oxygen generation assembly 2 is disposed outside the chamber, for example, within the installation space above the chamber.

[0059] The utility model provides high-purity oxygen to the oxygen chamber through the oxygen production component 2, pre-pressurizes the oxygen chamber through the third air valve 26, and cooperates with the pressure sensor in the oxygen chamber to control the pressure in the oxygen chamber. There is no need to wait for the pure oxygen to be stored to a certain pressure, which improves the pressurization efficiency, reduces the waiting time, and improves the user experience.

[0060] The air intake assembly can avoid breathing difficulties caused by unprepared or unavailable oxygen through the second one-way valve 38, thereby improving the user experience and fault tolerance. The air bag connected to the air intake box can absorb air flow fluctuations and play a buffering role.

[0061] The third one-way valve 54 of the exhaust assembly can supplement or buffer the exhaust. When the exhaust volume is large, the gas in the oxygen chamber can be used to buffer it, improving the user experience. The second airbag buffers the fluctuation of the exhaust air flow.

[0062] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
