Description

Technical Field

[0001] The present invention belongs to the technical field of hyperbaric oxygen chamber structures, and in particular relates to an integrated oxygen chamber. Background Art

[0002] A hyperbaric oxygen chamber is a sealed space that pumps pure oxygen and purified compressed air through pipes and a control system. This creates an environment with a pressure greater than one atmosphere and a higher oxygen concentration than outside, creating an environment conducive to oxygen absorption by the human body. It is used for medical treatment, cosmetic surgery, athletes, and for smoking supplements for individuals experiencing hypoxia in high altitudes and high mountains, as well as for fatigue relief. To withstand the high internal pressure, previous oxygen chambers were constructed entirely of steel. This made them bulky and difficult to transport, and storing them in homes required consideration of the floor's weight load. Previous chamber doors were made of metal, with only small or no observation windows, making it impossible to directly observe the working conditions within the chamber or the condition of those inside. Over time, those inside experienced feelings of stuffiness and heat, which could also cause physical and psychological side effects. Previous oxygen chambers were single-seat with fixed seats, and the sitting posture could not be adjusted at will according to the human body condition; previous oxygen chamber doors had no armrest inner panels, and there was no buffer device when the oxygen chamber door was opened; previous oxygen chambers were only independent cabins, and the cabin pressurization and oxygen production were all independent equipment outside the oxygen chamber. Summary of the Invention

[0003] In order to solve the technical problems existing in the prior art, the present invention provides an integrated oxygen cabin, comprising a right cabin body component, a left cabin body component, an interior cabin air duct, a seat, a lower side panel component, a rear side panel component, an armrest cover panel in a door, a small table panel, an interior cabin air duct, an interior trim panel, a base frame equipment compartment, an inflation and pressurization device, an air cooling and drying device, an oxygen generator and a cabin door. The left cabin body component and the right cabin body component are assembled in half into a sphere as a cabin body. The left cabin body component and the right cabin body component are installed on the base frame equipment compartment. The cabin body is the main carrier when high-pressure gas is injected and is made of fiberglass. The cabin body is provided with an air intake valve, an exhaust valve and an emergency exhaust valve; the rear side panel component comprises a rear side panel upper cover, a rear side panel lower cover and a drawer-type liftable water tank arranged between the rear side panel lower cover and the rear side panel upper cover. The rear side panel component is installed on the rear side of the lower side panel component, and the lower side panel component is installed on the outside of the base frame equipment compartment. The lower side panel component serves as an external cover panel of the cabin body and adopts a lightweight foam material to provide an aesthetically pleasing shape for the exterior of the cabin body.

[0004] An inflation and pressurization device is installed on the front side of the base skeleton equipment cabin, and an air cooling and drying device and an oxygen production device are installed on the rear side of the base skeleton equipment cabin. The inflation and pressurization device compresses the air to generate high-pressure gas. The compressed gas contains a large amount of heat. It passes through the connecting pipe and enters the air cooling and drying device for heat dissipation and cooling to remove condensed water. The cooled gas enters the closed cabin, absorbs the heat of the air in the cabin, and uses the cooled air to pressurize the oxygen cabin; the oxygen production device separates the oxygen in the air and injects it into the closed cabin to increase the oxygen concentration in the cabin. When the sensor detects that the oxygen concentration and air pressure in the cabin meet the standards, the control system adjusts the equipment to keep the pressure and oxygen concentration in the cabin stable. When the pressure or oxygen concentration exceeds the standard setting, the excess air and oxygen are discharged through the exhaust valve.

[0005] The inside of the right cabin body and the left cabin body are both installed with door armrest covers. The inner cover of the left cabin body is provided with a mask oxygen pipe, which can be used directly with a handheld mask for oxygen inhalation, providing a comfortable oxygen inhalation environment for people with severe hypoxia in plateau areas; a multimedia connection bracket is provided on the inner cover of the left cabin body, which can be connected to mobile phones, tablets and other multimedia interfaces, so that customers can increase their rest and entertainment experience while resting; the seats are installed on the floor of the cabin body, providing comfortable seating, and can automatically adjust the sitting and lying postures to achieve personal comfort and improve The cabin provides a comfortable and comfortable experience for people in the oxygen cabin. A small table is installed on the cabin in front of the seat, which provides a convenient desktop operating platform for people in the cabin. An air duct is provided on the upper part of the cabin, and the gas input from the equipment outside the cabin enters the cabin through the air duct. The cabin door is installed on the left cabin component through a hinge. The cabin door is made of fully transparent material and can withstand the high pressure in the oxygen cabin. The door is locked with gear engagement. The interior panel is installed on the outside of the movement mechanism at the rear of the seat to prevent dust, debris or hair from being drawn into the adjustment mechanism of the seat, thereby protecting the movement mechanism.

[0006] The hatch door is provided with a hatch frame tooth profile on the outer periphery, and a cabin door frame tooth profile is provided on the left cabin body component. A rotating mechanism is provided in the center of the hatch door, which can rotate around its own center. When closing the hatch door, the hatch door handle is rotated, and the hatch door frame tooth profile is buckled into the cabin door frame tooth profile. The hatch door frame tooth profile and the cabin door frame tooth profile cooperate to form a barb, which locks the hatch door and prevents the hatch door from opening when the cabin is under high pressure.

[0007] The hatch is provided with a buffer spring and an auxiliary protection spring at the hinge to assist in the rotation elastic force. The auxiliary protection spring is a failure protection mode of the buffer spring. When the hatch rotates counterclockwise to open, the buffer spring is compressed during counterclockwise rotation. After the buffer spring rotates past the horizontal state, when the hatch continues to rotate, the buffer spring releases the compression force to assist the hatch frame tooth profile to rotate open; when the hatch frame tooth profile rotates clockwise, in order to lock the hatch, the buffer spring rotates past the horizontal state to assist in locking the hatch; when the hatch is closing, the buffer spring uses the elasticity of the gas spring to assist in opening and closing the hatch. When the auxiliary protection spring is insufficiently elastic or its elasticity disappears, the auxiliary protection spring prevents the hatch from opening and closing suddenly.

[0008] An active radial seal is installed at the mating surface between the left hull and the hatch. This seal is comprised of a rubber sealant. In its natural state, the sealant is concave. A compressor inflates the sealant, causing it to bulge under high pressure into a convex shape, clinging tightly to the surrounding structural cavity. When the hatch is closed and locked, the sealant is inflated, transforming its original concave shape into a convex one, oriented toward the center of the hatch. This bulge then comes into direct contact with the hatch's mating surface. When inflation reaches a certain pressure, the seal between the left hull and the hatch is sealed, reducing friction between the active radial seal and the hatch. This pressure creates a superior seal. When the hatch needs to be opened, negative pressure is applied to the sealant, causing the original convex shape to return to a concave shape, releasing the seal.

[0009] Beneficial effects:

[0010] 1. The present invention solves the problem of the oxygen chamber being too bulky. The chamber body is made of fiberglass and is lightweight. The door solves the visual problem and solves the psychological side effects of the human body caused by visual obstruction.

[0011] 2. The hatch of the oxygen cabin of the present invention is opened by side rotation. The hatch is provided with a rocker arm rotation and a buffering motion device when opening and closing. In order to make the hatch door easy to open and close, an auxiliary rotation guide mechanism and a limit mechanism are provided during the hatch door rotation process, and the progressive opening and closing experience is improved; the hatch door seal is an active stamping rubber sealing method, and the sealing direction points to the center of the circle, which reduces the friction between the sealing rubber and the hatch door, and alleviates the huge external force on the hatch door caused by the superposition of the pressure generated by the sealing compression and the internal air pressure. The hatch door is airbag sealed. After closing the door, the airbag is inflated and pressurized to enhance the sealing. After the airbag is deflated and the pressure is reduced, the sealing is reduced, and the hatch door is opened; the door is opened and closed, and the door is slowly opened or closed under the thrust of the slow-out gas spring after the gas spring passes the dead point position.

[0012] 3. The present invention has an integrated structure. All electrical equipment is integrated at the bottom, the air compressor is noise-reduced, and the oxygen cabin integrates pressurization, pressure control, pressure reduction, exhaust ventilation and oxygen production functions into one, without the need for external equipment. At the same time, in order to prevent people from feeling stuffy in the cabin, cabin ventilation, temperature control and regulation, humidity control and regulation, oxygen concentration testing, ozone sterilization and automatic control are added, and equipment noise reduction is achieved through sound insulation settings of each module.

[0013] 4. The sitting posture in the oxygen chamber of the present invention can be adjusted to adapt to different human physical conditions, achieve the best comfort experience, and ensure sufficient sitting comfort space.

[0014] 5. The present invention intelligently optimizes the hyperbaric oxygen chamber and uses composite materials for the chamber body, providing a comfortable and intelligent hyperbaric oxygen chamber environment. It is equipped with oxygen delivery, comfortable automatically adjustable seats, a small table, air cooling and drying, and has developed a door power-assisted opening and closing device, a power-assisted locking device, and a door sealing device.

DETAILED DESCRIPTION

[0028] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to 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.

[0029] An integrated oxygen cabin comprises a right cabin body component 2, a left cabin body component 1, an in-cabin air duct 6, a seat 8, a lower side panel component 3, a rear side panel component, an inner door armrest cover 4, a small table panel 5, an interior panel, a base frame equipment cabin 9, an air charging and pressurizing device 10, an air cooling and drying device 11, an oxygen generator 12 and a cabin door 7. The left cabin body component 1 and the right cabin body component 2 are assembled in half into a sphere as a cabin body. The left cabin body component 1 and the right cabin body component 2 are installed on the base frame equipment cabin 9. The cabin body is filled with high-pressure gas. The main bearing body is made of fiberglass, and the cabin is provided with an air intake valve, an exhaust valve and an emergency exhaust valve; the rear side panel comprises a rear side panel upper cover 19, a rear side panel lower cover 21 and a drawer-type liftable water tank 20 arranged between the rear side panel lower cover and the rear side panel upper cover, the rear side panel is installed on the rear side of the lower side panel component 3, the lower side panel component 3 is installed on the outside of the base frame equipment compartment 9, the lower side panel component 3 is the external cover panel of the cabin, and is made of lightweight foam material to provide an aesthetically pleasing shape for the exterior of the cabin.

[0030] An inflation and pressurizing device 10 is installed on the front side of the base skeleton equipment cabin 9, and an air cooling and drying device 11 and an oxygen production device 12 are installed on the rear side of the base skeleton equipment cabin 9. The inflation and pressurizing device 10 compresses the air to generate high-pressure gas. The compressed gas contains a large amount of heat. After passing through the connecting pipeline, it enters the air cooling and drying device 11 for heat dissipation and cooling to remove condensed water. The cooled gas enters the closed cabin, absorbs the heat of the air in the cabin, and uses the cooled air to pressurize the oxygen cabin; the oxygen production device 12 separates the oxygen in the air and injects it into the closed cabin to increase the oxygen concentration in the cabin. When the sensor detects that the oxygen concentration and air pressure in the cabin meet the standard, the control system adjusts the equipment to keep the pressure and oxygen concentration in the cabin stable. When the pressure or oxygen concentration exceeds the standard setting, excess air and oxygen are discharged through the exhaust valve.

[0031] The inside of the right cabin component 2 and the left cabin component 1 are both installed with door armrest cover panels 4, and the inner cover panel of the left cabin component 1 is provided with a mask oxygen pipe, so that oxygen can be directly inhaled using a handheld mask; the seat 8 is installed on the floor of the cabin, providing a comfortable seat 8 to sit on, and can automatically adjust the sitting posture and other sitting postures to achieve self-comfort and improve the human experience in the oxygen cabin; a small table board 5 is installed on the cabin in front of the seat 8, and the small table board 5 provides a convenient desktop operating platform for the personnel in the cabin; an in-cabin air duct 6 is provided on the upper part of the cabin, and the gas input by the external equipment of the cabin enters the interior of the cabin through the in-cabin air duct 6; the cabin door 7 is installed on the left cabin component 1 by hinges, and the cabin door 7 is made of a fully transparent material and can withstand the high pressure in the oxygen cabin. The cabin door 7 is locked by gear engagement; the interior panel is installed on the outside of the movement mechanism at the rear of the seat 8 to prevent dust, debris or hair-like substances from being drawn into the adjustment mechanism of the seat 8, thereby protecting the movement mechanism.

[0032] The hatch door 7 is provided with a hatch frame tooth shape 14 on the periphery, and a cabin door frame tooth shape 13 is provided on the left cabin body component 1. A rotating mechanism is provided in the center of the hatch door 7, which can rotate around its own center. When the hatch door 7 is closed, the hatch door handle is rotated, and the hatch frame tooth shape 14 is buckled into the cabin door frame tooth shape 13. The hatch frame tooth shape 14 and the cabin door frame tooth shape 13 cooperate to form a barb, which locks the hatch door 7 and prevents the hatch door 7 from opening when the high pressure in the cabin is high.

[0033] The hatch 7 is provided with a buffer spring 15 and an auxiliary protection spring 17 at the hinge for assisting the rotation elastic force. The auxiliary protection spring 17 is a failure protection mode of the buffer spring 15. When the hatch 7 is rotated counterclockwise to open, the buffer spring 15 is compressed during counterclockwise rotation. After the buffer spring 15 rotates past the horizontal state, when the hatch 7 continues to rotate, the buffer spring 15 releases the compression force to assist the hatch frame tooth shape 14 to rotate open; when the hatch frame tooth shape 14 rotates clockwise, in order to lock the hatch 7, the buffer spring 15 rotates past the horizontal state to assist the hatch 7 in locking; when the hatch 7 is in the process of closing, the buffer spring 15 uses the elasticity of the gas spring to assist the opening and closing of the hatch 7. When the auxiliary protection spring 17 is insufficiently elastic or its elasticity disappears, the auxiliary protection spring 17 prevents the hatch 7 from opening and closing suddenly when closing.

[0034] An active radial seal 16 is installed at the mating surface between the left cabin component 1 and the hatch 7. The active radial seal 16 is a sealing rubber structure. The sealing rubber is naturally concave. A compressor inflates the sealing rubber, causing it to bulge into a convex shape under high pressure and adhere closely to the structural cavity surrounding the rubber. After the hatch 7 is closed and locked, the sealing rubber is inflated, causing the original concave shape to bulge into a convex shape, with the bulge direction toward the center of the hatch 7. After the bulge, it directly contacts the mating surface of the hatch 7. When the air reaches a certain pressure, the left cabin component 1 and the hatch 7 are sealed, reducing friction between the active radial seal 16 and the hatch 7. A better sealing effect is achieved through the inflation pressure. When the hatch 7 needs to be opened, negative pressure is applied to the active radial seal 16, causing the original convex shape to return to a concave shape, releasing the seal.

[0035] When an element is referred to as being “fixed to” or “disposed on” another element, it can be directly on the other element or indirectly on the other element; when an element is referred to as being “connected to” another element, it can be directly connected to the other element or indirectly connected to the other element.

[0036] The directional terms such as left, right, up, down, etc. in this embodiment are merely relative concepts or are based on the normal use state of the product and should not be considered as restrictive.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
