DETAILED DESCRIPTION

[0066] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0067] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0068] like Figure 1 and Figure 2 As shown, it is a structural diagram of a negative ion micro-hyperbaric oxygen chamber provided in an embodiment of the present invention, wherein the negative ion micro-hyperbaric oxygen chamber comprises: a chamber 1, a sealing door assembly 2 is provided on one side of the chamber 1, an air supply assembly 4 is provided in the chamber 1, an oxygen supply control chamber 6 is provided in the chamber 1, a negative ion supply assembly 8 is provided on one side of the oxygen supply control chamber 6, and a pressure relief assembly 7 is provided in the chamber 1;

[0069] The oxygen supply control chamber 6 comprises:

[0070] An oxygen generator 601 is disposed on one side of the cabin 1, and one side is fixedly connected to the cabin 1;

[0071] A delivery pipeline 602, which is disposed on one side of the oxygen concentrator 601, with one end of the delivery pipeline 602 fixedly connected to the output port of the oxygen concentrator 601 and the other end of the delivery pipeline 602 fixedly connected to the cabin 1;

[0072] Specifically, by opening the sealed door assembly 2, the user enters the cabin 1 through the sealed door assembly 2. When the user enters the cabin 1, the oxygen generator 601 is started, and the oxygen produced by the oxygen generator 601 flows into the delivery pipe 602. The delivery pipe 602 delivers the oxygen produced by the oxygen generator 601 to the cabin 1 through the air supply assembly 4, thereby completing the continuous supply of oxygen to the cabin 1. At the same time, the negative ion concentration in the cabin 1 is adjusted by the negative ion supply assembly 8; when oxygen is continuously input into the cabin 1 for a period of time, the pressure in the cabin 1 will continue to increase, and the pressure in the cabin 1 can be adjusted by the pressure relief assembly 7; in addition, a seat assembly 3 is also provided in the cabin 1 to facilitate the user to rest in the cabin 1.

[0073] like Figure 3 As shown, as a preferred embodiment of the present invention, the negative ion supply component 8 includes:

[0074] A negative ion generator 801 is disposed on one side of the cabin 1;

[0075] A negative ion delivery port 802 is provided on the cabin 1 and is connected to the output end of the negative ion generator 801 through a transmission pipeline;

[0076] Specifically, by starting the negative ion generator 801, the negative ions produced by the negative ion generator 801 flow to the negative ion delivery port 802 through the transmission pipeline, and the negative ions flow into the cabin 1 from the negative ion delivery port 802, thereby completing the adjustment of the negative ion concentration in the cabin 1;

[0077] The seat assembly 3 comprises:

[0078] A base 303, wherein the base 303 is disposed in the cabin 1, and one side of the base 303 is fixedly connected to the cabin 1;

[0079] An adjusting shaft 302, wherein the adjusting shaft 302 is disposed through the base 303 and is rotatably connected to the base 303;

[0080] A backrest 301, wherein the backrest 301 is disposed on one side of the base 303, and one end of the backrest 301 is rotatably connected to the base 303 via the adjustment shaft 302;

[0081] Specifically, the adjusting shaft 302 is driven to rotate by the driving member, and the adjusting shaft 302 drives the backrest 301 to rotate, so as to adjust the angle of the backrest 301;

[0082] The sealing door assembly 2 comprises:

[0083] A door shell 201, wherein the door shell 201 is disposed on one side of the cabin body 1, and one side of the door shell 201 is rotatably connected to the cabin body 1;

[0084] A door handle 202, which is disposed on one side of the door shell 201 and is used to drive the door shell 201 to rotate;

[0085] A sealed inner door 203, which is disposed on one side of the door shell 201 and is in contact with the cabin body 1;

[0086] Specifically, the door handle 202 is pulled to drive the door shell 201 to rotate, and the door shell 201 drives the sealed inner door 203 to rotate, thereby providing a passage for the user to enter the cabin 1; when the user enters the cabin 1, the door handle 202 drives the door shell 201 to reset, and the door shell 201 drives the sealed inner door 203 to reset, so that the sealed inner door 203 recovers the interference connection with the cabin 1, thereby improving the sealing inside the cabin 1.

[0087] like Figure 4 and Figure 5 As shown, as a preferred embodiment of the present invention, the air supply component 4 includes:

[0088] An air supply port 401, wherein the air supply port 401 is provided on the cabin body 1;

[0089] Two groups of check valves 402, the two groups of check valves 402 are symmetrically arranged on the corresponding air delivery ports 401, and one end of the two groups of check valves 402 is rotatably connected to the cabin 1 through a corresponding rotating shaft, and a first torsion spring is provided on the rotating shaft;

[0090] In this embodiment, one end of the first torsion spring is fixedly connected to the cabin 1, and the other end is fixedly connected to the check valve 402, and the first torsion spring is interlaced with the rotating shaft; in addition, the air delivery port 401 can be provided in several groups;

[0091] Specifically, the initial state of the two check valves 402 is a conflicting connection. When oxygen flows out of the delivery pipeline 602, the impact force of the outflowing oxygen causes the two check valves 402 to rotate around the corresponding rotating shafts, and the two check valves 402 end the conflicting connection state, and oxygen flows into the cabin 1. When the flow rate of the delivery pipeline 602 is too low, the first torsion spring resets the two check valves 402 according to its own characteristics, restores the conflicting connection state, and prevents the phenomenon of oxygen backflow;

[0092] It should be noted that the deformation of the first torsion spring (rotation of the check valve 402) is caused by the pressure difference between the delivery pipeline 602 and the cabin 1. The minimum pressure difference that causes the deformation of the first torsion spring should be greater than the pressure difference required for oxygen reflux. Based on this, the stiffness coefficient of the first torsion spring set at the air delivery port 401 can be determined.

[0093] like Figure 6 As shown, as a preferred embodiment of the present invention, the pressure relief component 7 includes:

[0094] A pressure relief port 701 is provided on the cabin 1;

[0096] In this embodiment, one end of the second torsion spring is fixedly connected to the cabin 1, and the other end is fixedly connected to the check valve 402, and the second torsion spring is interlaced with the rotating member;

[0097] Specifically, when the pressure in the cabin 1 is too high, the pressure inside the cabin 1 will force the pressure relief valve 702 to rotate around the rotating member, ending the conflicting connection state between the two sets of pressure relief valves 702, so that the pressure in the cabin 1 is released to the outside of the cabin 1 through the pressure relief port 701. When the pressure in the cabin 1 is lower than the maximum pressure, the second torsion spring provided on the rotating member will reset the pressure relief valve 702, restoring the conflicting connection state between the two sets of pressure relief valves 702.

[0098] It should be noted that when the pressure in the cabin 1 exceeds the standard pressure value, the pressure relief valve 702 will be pushed to cause deformation of the second torsion spring, thereby ending the interference connection state between the two sets of pressure relief valves 702. The minimum force that causes the second torsion spring to deform is equal to the thrust generated by the maximum pressure in the cabin 1. Based on this, the stiffness coefficient of the second torsion spring set at the pressure relief port 701 can be determined.
