[0002] Microbaric oxygen chamber is a special equipment for microbaric oxygen therapy. It has a wide range of applications, mainly used for health care and rehabilitation of hypoxic diseases, beauty care and energy recovery. Microbaric oxygen chamber can be used to relieve respiratory diseases, and it also meets the oxygen needs of people in high-altitude areas and people who work with high-intensity brains.

[0003] There are many safety hazards in the use of micro-pressure oxygen chambers. For example, oxygen is a flame retardant. Once it encounters fire, the aircraft may be destroyed and people may die. There is a risk of fire if electrical appliances are installed in the cabin, which can easily cause sparks. The overly dry cabin environment can easily lead to static electricity accumulation. When static electricity accumulates too much, it will inevitably cause fire. The sponge filling the sofa seats in the cabin is flammable and burns very intensely under high oxygen partial pressure environments. A large amount of dust and human volatile substances are deposited in the cabin, which are difficult to clean and can easily lead to the division and reproduction of bacteria and viruses.

[0004] According to the Chinese patent with the announcement number CN109984900A, a new type of shared oxygen cabin is disclosed. The device provides pure oxygen into the cabin through the oxygen production module, and the golden needle negative ion generator module releases negative ions into the cabin. While breathing oxygen in the cabin, people can massage and relax through the seats provided in the shared oxygen cabin. The intelligent control module is used to realize intelligent control of the system, and the mobile phone APP is used to connect with the shared oxygen cabin to realize the opening, closing and payment of the shared oxygen cabin, so as to understand the user's body data in real time and realize data upload and sharing;

[0005] According to the Chinese patent with the announcement number CN219814579U, an oxygen booster device for a micro-compression oxygen chamber is disclosed. The oxygen booster device for a micro-compression oxygen chamber drives a fan to evacuate the installation box through an exhaust pipe to form a negative pressure, and at the same time uses an air intake box to extract dust accumulated on the bottom wall of the inner cavity of the micro-compression oxygen chamber body to the inside of the installation box, and uses a dustproof plate to block the dust, thereby achieving the purpose of collecting dust;

[0006] In the above scheme, the sofa seats placed in the cabin occupy a large activity space in the cabin. When cleaning the dust and human volatile substances in the cabin, there are dead corners or spaces that are difficult to clean. When using a vacuum cleaner for cleaning, one person cannot move the sofa seats to other locations, resulting in a large amount of dust and human volatile substances deposited in the cabin. These deposits are difficult to clean in the cabin and can easily lead to the division and reproduction of bacteria and viruses. Summary of the invention

[0020] 1. When it is necessary to use a vacuum cleaner to clean the dust and sediment inside the cabin of the splicable micro-compression oxygen cabin, first open the cabin door, drive the support frame and the seat to rotate to the position opposite to the cabin door through the hydraulic rod squeezing and pushing clamping mechanism, and then alternately start the two motors on the cross arm to drive the two screw rods inside the cross arm and the two semicircular sliders to thread the transmission, so that the support frame and the seat are pushed in batches by the upper and lower traction arms on the cross arm to move out of the cabin.

An anti-deflection block is fixed in the middle of the arc surface of the semicircular slider 607. The upper and lower sides of the cross arm 604 are respectively provided with a short slideway and a long slideway for the two anti-deflection blocks to slide, and the ends of the anti-deflection blocks are movably connected with a traction arm 608. When the anti-deflection blocks on the two semicircular sliders 607 move along the short slideway and the long slideway respectively, the semicircular sliders 607 can be prevented from deflecting during movement, and when the two semicircular sliders 607 are on the cross arm When the inner part of 604 moves, the arc-shaped surfaces of the two semicircular sliders 607 move in contact with the inner wall of the cross arm 604, so that the two semicircular sliders 607 will not cause interference. The end of the traction arm 608 away from the anti-deflection block is provided with a round protrusion and an arc-shaped hook, and the surface of the side of the cross arm 604 close to the support frame 5 is connected with an elastic pin 611 through a spring. The middle part of the support frame 5 is provided with a clamping mechanism 7, which includes a clamping seat 701 embedded in one side of the support frame 5, and the clamping seat 701 is clamped with the round protrusion of the traction arm 608, and the clamping seat 701 is closed. Symmetrically distributed on the horizontal center line of the cross arm 604, a reserved hole for plugging with the arc hook is opened on one side of the support frame 5. When the traction arm 608 is docked with the reserved hole on one side of the support frame 5 through the arc hook, the traction arm 608 moves along the cross arm 604 to stably push and pull the support frame 5, and when the traction arm 608 pushes the support frame 5 out of the cabin 1, the traction arm 608 rotates around the round protrusion to make the arc hook disengage from the reserved hole. When the traction arm 608 is pulled to drive the round protrusion to withdraw the card seat 701, it is convenient to complete the disassembly of the traction arm 608 and the support frame 5;

[0050] The rotating column 601 is composed of an upper cylinder and a lower rotating block, two vertical sides of the rotating block are parallel surface structures, and the other two vertical sides of the rotating block are arc structures, the slide groove 401 is a stepped structure, and a C-shaped opening is opened at one end of the bottom of the slide groove 401, the upper side width of the slide groove 401 matches the diameter of the cylinder of the rotating column 601, the lower side width of the slide groove 401 matches the vertical side width of the rotating block, and the C-shaped opening diameter of the slide groove 401 matches the diameter of the rotating block;

[0051] A hydraulic rod 402 is movably connected in the interlayer of the pad 4 near the slide 401, a cross bar 602 and abutment block 603 are welded in parallel on the cylinder on the upper part of the rotating column 601, the output end of the hydraulic rod 402 is rotatably connected to the cross bar 602, and a right-angle piece 403 is welded on the upper side surface of the pad 4 near one end of the slide 401.

[0052] In specific implementation, when it is necessary to use a vacuum cleaner to clean the dust and sediment inside the cabin body 1, first open the cabin door 2, then start the hydraulic rod 402 to extend and squeeze the cross bar 602 to drive the rotating column 601 to rotate forward, at this time, the rotating block at the bottom of the rotating column 601 completes a 90° flip in the C-shaped opening at one end of the slide groove 401, and at this time, the abutment block 603 on the rotating column 601 will fit and abut one side of the right-angle piece 403 parallel to the slide groove 401, and at the same time, one of the arc surfaces of the rotating block will be aligned with the opening of the C-shaped opening;

[0053] The hydraulic rod 402 is continuously driven to push the cross bar 602 to drive the rotating column 601 to move forward along the slide groove 401. At this time, the two vertical parallel surfaces of the rotating column 601 will not deflect when sliding along the slide groove 401, so that the clamping mechanism 6 drives the support frame 5 and the seat 501 to move straight along the slide groove 401 until the seat 501 on one side of the cross arm 604 is opposite to the position of the cabin door 2; then the motor 605 on the upper part of the cross arm 604 is started to drive the screw rod 606 on the upper part of the cross arm 604 to move forward. The screw rod 606 on the upper part of the cross arm 604 and the semicircular slider 607 are threadedly driven to drive the traction arm 608 to squeeze the first support frame 5 near the position of the cabin door 2. When the traction arm 608 squeezes the clamping seat 701, the guide seat 609 guides the support frame 5 to assist the support frame 5 to move the seat 501 to the outside of the cabin body 1. When the traction arm 608 on the upper side of the cross arm 604 is removed, it is convenient for personnel to move the first seat 501 out of the narrow exit position of the cabin door 2.

[0054] Afterwards, the motor 605 on the upper part of the cross arm 604 is controlled to stop rotating, and the motor 605 on the lower part of the cross arm 604 is started to drive the screw rod 606 and the semicircular slider 607 at the lower part of the cross arm 604 to transmit the threaded transmission, so that the traction arm 608 on the lower side of the cross arm 604 pushes the second support frame 5 in the cabin 1 to move forward along the slide groove 401 again until the second support frame 5 abuts against one side of the guide seat 609, and the traction arm 608 is driven by the screw rod 606 that continues to rotate to push the second support frame 5 and the seat 501 out of the cabin 1. When the traction arm 608 on the lower side of the cross arm 604 is removed, it is convenient for personnel to move the second seat 501 out of the narrow exit position of the cabin door 2, and it is convenient for personnel to vacuum and clean the interior of the cabin 1 where the two seats 501 have been moved out without dead angles.

[0055] On the contrary, when placing the seat 501 into the cabin body 1 again, the support frame 5 under the first seat 501 is connected to the semicircular slider 607 under the cross arm 604 through the traction arm 608, and the motor 605 under the cross arm 604 is started to reverse, which can pull the support frame 5 under the first seat 501 toward the cross arm 604. The motor 605 that continues to reverse will drive the first seat 501 to move into the cabin body 1 first through the screw rod 606, and then the support frame 5 under the second seat 501 is connected to the semicircular slider 607 above the cross arm 604 through the traction arm 608, and the motor 605 above the cross arm 604 is started to reverse, which can pull the support frame 5 under the second seat 501 toward the cross arm 604. The motor 605 moves closer and continues to reverse, driving the second seat 501 to move into the cabin 1 through the screw rod 606, so that the two seats 501 can be put back on the clamping mechanism 6; finally, the hydraulic rod 402 is started in reverse to contract and pull the cross bar 602 and drive the rotating column 601 to slide in the opposite direction along the slide groove 401 until the rotating block at the bottom of the rotating column 601 enters the C-shaped opening, and the hydraulic rod 402 is started again to pull the cross bar 602 to drive the rotating column 601 to deflect 90° in the opposite direction in the C-shaped opening, so that the abutment block 603 on the rotating column 601 abuts against the right-angle piece 403 perpendicular to the direction of the slide groove 401. At this time, the clamping mechanism 6 can drive the support frame 5 and the seat 501 to return to their original position.

[0056] See also Figure 7-Figure 9 A dustproof folding cloth is bonded between the top opening edge of the slide 401 and the rotating column 601. When the rotating column 601 moves in the forward and reverse directions along the slide 401, the dustproof folding cloth can separate the slide 401 inside and outside, preventing dust and sediment inside the cabin 1 from falling into the slide 401 and causing cleaning difficulties.

[0057] See also Figure 7 , Fig.10 , Figure 12-14 A guide seat 609 is welded to one end of the cross arm 604 away from the motor 605. A limit frame 610 is passed through the lower side of the guide seat 609. The limit frame 610 is composed of an upper handle and two threaded rods at the lower part. Nuts are sleeved on the outer side of the threaded rods of the limit frame 610. Two groups of positioning holes for plugging with the threaded rods are opened on the upper surface of the pad 4. The limit frame 610 and the pad 4 are vertically distributed;

[0058] During specific implementation, when the support frame 5 and the seat 501 are placed opposite to the touch screen 10 in the cabin, the limit frame 610 is moved downward along the guide seat 609 so that the two threaded rods of the limit frame 610 are inserted into one of the positioning holes on the upper surface of the pad 4, and then the nut is rotated along the threaded rod so that the nut squeezes the lower surface of the guide seat 609 to ensure that the limit frame 610 and the pad 4 complete the positioning support. When a person sits or lies in the seat 501, the cooperation of the rotating column 601, the limit frame 610 and the pad 4 can ensure that the support frame 5 and the seat 501 have a stable placement effect; when the cross arm 604 drives the seat 501 to face the exit of the cabin door 2, the two threaded rods of the limit frame 610 are inserted into another group of positioning holes on the upper surface of the pad 4 to ensure that the positioning support of the limit frame 610 and the pad 4 can limit the placement angle and position of the cross arm 604.

[0059] See also Fig.12 , Figure 15-19 The bottom of the seat 501 is supported by two parallel support frames 5. An adjusting roller 702 is connected between two adjacent support frames 5 through a central axis. An adjusting groove 708 is provided on the outer peripheral side of the surface of the adjusting roller 702. The adjusting groove 708 is composed of straight grooves at both ends and a spiral groove in the middle. The adjusting groove 708 is connected to the elastic pin 611 on the surface of the cross arm 604. Coil springs 703 are sleeved on both sides of the central axis of the adjusting roller 702. The two ends of the coil spring 703 are respectively fixed to the adjusting roller 702 and the support frame 5.

[0060] Gears 704 are fixed at both ends of the central axis of the adjusting roller 702, and a gear ring 705 is meshed on one side of the gear 704. The gear ring 705 is slidably connected to the surface of the support frame 5. A protrusion 706 is provided on the outer side of the upper part of the gear ring 705. A tension spring 707 is connected between the lower end of the gear ring 705 and the support frame 5. The inner concave side of the support frame 5 close to the cross arm 604 and the inner side of the gear ring 705 are both provided with a U-shaped notch for the elastic pin 611 to move through.

[0061] In specific implementation, after the hydraulic rod 402 pushes the rotating column 601 and the cross arm 604 to move to the limit position of the hatch 2 position, the motor 605 of the cross arm 604 is started to rotate forward to drive the screw rod 606 and the semicircular slider 607 on the inner side of the cross arm 604 to transmit the thread, so that the two traction arms 608 on the cross arm 604 squeeze the two support frames 5 and the cross arm 604 to slide relative to each other, so that the adjusting roller 702 in the middle of the support frame 5 will be squeezed by the elastic pin 611 on the surface of the cross arm 604 through the spiral groove in the middle of the adjusting groove 708, so that the adjusting roller 702 rotates and drives the gears 704 and the gear ring at both ends of the central shaft. 705 is positively meshed, so that the gear ring 705 rotates downwardly toward the support frame 5. The traction of the tension spring 707 on the gear ring 705 causes the protrusion 706 on the outer side of the gear ring 705 to abut against the clamping seat 701 for limiting. Through the restriction of the adjusting roller 702 by the coil spring 703 and the restriction of the gear ring 705 by the tension spring 707, the positions of the adjusting roller 702 and the gear ring 705 will not change at this time, thereby facilitating the subsequent re-installation and docking of the support frame 5 and the seat 501 with the clamping mechanism 6. When the gear ring 705 is disengaged from the cross arm 604, the support frame 5 and the seat 501 can be quickly guided out of the cabin 1 by squeezing the traction arm 608.

[0062] When the coil spring 703 limits the position of the adjusting roller 702 and the tension spring 707 limits the position of the gear ring 705, the straight groove at one end of the adjusting groove 708 will be aligned with the U-shaped notch on the surface of the support frame 5 and the gear ring 705, and at this time, the elastic pin 611 close to the cabin door 2 is in a plug-in state with the straight groove at one end of the adjusting groove 708; conversely, when the support frame 5 is re-docking and installed on one side of the cross arm 604, the adjusting groove 708 on the surface of the adjusting roller 702 is docked with the elastic pin 611 on the side of the cross arm 604 close to the cabin door 2, and when the seat 501 that first enters the cabin body 1 follows the traction arm 608 under the cross arm 604 to move into the cabin body 1, the seat 501 that first enters the cabin body 1 will cause the adjusting roller 702 to rotate for the first time through the adjusting groove 708 and the elastic pin 611 close to the cabin door 2, and when the adjusting roller 702 is out of contact with the elastic pin 611, the seat 501 that first enters the cabin body 1 will cause the adjusting roller 702 to rotate for the first time The section roller 702 is reversely deflected and reset. When the seat 501 that first enters the cabin body 1 drives the adjusting roller 702 below to move to the position of the elastic pin 611 away from the cabin door 2, the seat 501 that first enters the cabin body 1 will cause the adjusting roller 702 below and the second elastic pin 611 to rotate for the second time, so that the seat 501 that first enters the cabin body 1 can clamp the cross arm 604 through the gear ring 705 below and the support frame 5; when the seat 501 that enters the cabin body 1 later follows the traction arm 608 above the cross arm 604 to move into the cabin body 1, the seat 501 that enters the cabin body 1 later can cause the adjusting roller 702 below to rotate for the first time with the elastic pin 611 close to the cabin door 2 through the adjusting groove 708, so that the seat 501 that enters the cabin body 1 later can clamp the cross arm 604 through the gear ring 705 and the support frame 5, ensuring that the two seats 501 have a quick assembly and clamping effect when they are re-installed into the cabin body 1.

[0063] In summary, when the micro-pressure oxygen chamber of the present invention is working, the power is first turned on, the device enters the initialization standby state, the air conditioning control system performs autonomous regulation according to the current temperature and humidity in the cabin 1, the user pushes the cabin door 2 inward into the cabin 1, closes the cabin door 2, sets the oxygen therapy data on the cabin touch screen 10, connects the oxygen mask to the mask oxygen interface 12, the user puts on the mask, the user can adjust the sitting posture through the seat 501, and then clicks on the start of the cabin touch screen 10 or the cabin touch screen 801, the system starts to run automatically, and the gas generated by the air compressor 16 passes through the cooler 18, the gas storage tank 22, and the filter The device 17 enters the cabin 1, and the pressure of the cabin 1 increases.
