DETAILED DESCRIPTION

[0042] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described 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.

[0043] The present invention is described in further detail below with reference to the accompanying drawings:

[0044] An oxygen supply device for an oxygen cabin, such as Figure 1-4As shown, it includes an air intake assembly 3 arranged in the oxygen cabin, 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 through the second air valve 35. Figure 1 and Figure 3 Only the internal space of the oxygen chamber is shown in the figure, and the external structure of the oxygen chamber is the existing technology, which will not be described in detail in this utility model.

[0045] 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.

[0046] The second gas valve may be a normally open solenoid valve, which keeps the buffer passage unobstructed in the event of a power outage.

[0047] The air inlet box 31 is connected to the first air valve 33, the three-way valve 39 and the breathing mask 4 in sequence; the second air valve 35 is connected to the three-way valve 39; the air inlet box 31 is also connected to the first one-way valve 37. The second air valve 35 is used to control whether oxygen is supplied to the breathing mask 4; the first one-way valve 37 provides a buffer for the air inlet box 31. The first air bag 32 is connected to the air inlet box 31 to control the fluid pressure in the breathing mask.

[0048] 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.

[0049] 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 prevent the second one-way valve from being blocked.

[0050] The three-way connection 39 is connected to the breathing mask 4 via the air supply pipe 42. A flow meter 41 is installed on one side of the air supply pipe 42 to monitor the respiratory flow. The middle 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 the air inlet pipe 21.

[0051] 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.

[0052] The oxygen supply device of the present invention also includes an exhaust assembly 5, which includes an exhaust box 52 and a second exhaust pipe 55. The exhaust box 52 is connected to the breathing mask 4 via 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. Exhaled gas from the breathing mask 4 is discharged outside the oxygen chamber 6 through the first exhaust pipe, the exhaust box, and the second exhaust pipe 55. The second exhaust pipe 55 is provided with an exhaust valve 56 for controlling the opening of the exhaust valve.

[0053] Among them, the exhaust box 52 is also connected to any of the following components or their combination: a second airbag 53 and a third one-way valve 54; 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 jitter or fluctuation of airflow.

[0054] When exhaust valve 56 is open, controlling its opening requires adjusting airflow, air pressure, and other parameters. Therefore, control of exhaust valve 56 exhibits a certain degree of hysteresis. Second airbag 53 and third one-way valve 54 effectively absorb airflow fluctuations during this lag period. Third one-way valve 54 prevents breathing difficulties caused by accidental valve closure. Furthermore, if the exhaust volume is high and the pressure inside the oxygen chamber exceeds the pressure inside the exhaust box, the exhaust box compensates for the pressure. Specifically, the air inside the oxygen chamber enters the exhaust box through third one-way valve 54 and is discharged from the oxygen chamber through the second exhaust pipe.

[0055] Figure 5 The control component 7 of the present invention is shown. A heating wire 511 and a temperature sensor 512 are provided in the first exhaust pipe 51. The control component 7 is connected to the exhaust valve 56, the oxygen production component 2, the second gas valve 35, the heating wire 511 and the temperature sensor 512 respectively.

[0056] The control component 7 can adopt a microcontroller MCU, a controller CPU, or a combination thereof. By detecting the temperature inside 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 4The 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] Figure 2 The specific design of the oxygen assembly 2 is also shown: the oxygen assembly 2 comprises an air compressor 22, a cold dryer 23, an oxygen-generating molecular sieve 24, and a first pressure-reducing valve 25. The output of the air compressor 22 is connected to the input of the cold dryer 23, which in turn is connected to a fourth air valve 28 and a third air valve 26, respectively. The fourth air valve 28 is connected to the oxygen-generating molecular sieve 24, which in turn is connected to the first pressure-reducing valve 25, which is connected to the air inlet pipe 21 to provide oxygen. The third air valve 26 communicates with the interior of the oxygen chamber 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 pressurizes the chamber to maintain the chamber within the set pressure range, improving pressurization efficiency, reducing waiting time, and enhancing the user experience. Simultaneously, the oxygen-generating molecular sieve generates oxygen. Once the oxygen pressure reaches the preset pressure range, oxygen is supplied to the air inlet assembly 3 through the first pressure-reducing valve 25. The oxygen production component 2 is arranged outside the oxygen chamber, for example, in the installation space above the oxygen 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.
