For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] The oxygen chamber according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0049] See also Figures 1 to 4According to the oxygen cabin of the first embodiment of the present invention, it includes an oxygen cabin body 1, a seat 2 or a bed arranged in the oxygen cabin body 1, and a host for delivering oxygen to the oxygen cabin body 1 and adjusting the air pressure. The oxygen cabin body 1 is provided with a door body 3. When the door body 3 is in a locked state, the interior of the oxygen cabin body 1 is a closed space. The host can be composed of an oxygen generator, an air compressor, a temperature regulating device, a control circuit, etc., which are arranged in a host room 4. The oxygen generator is used to supply high-concentration oxygen, the air compressor is used to supply high-pressure air, the temperature regulating device is used to adjust the internal temperature of the oxygen cabin body 1, and the control circuit is used to control the operation of components such as the oxygen generator, the air compressor, and the temperature regulating device. This embodiment does not limit the specific structure of the host. The oxygen cabin may also include a control panel 5 arranged outside the oxygen cabin body 1, and the control panel 5 can be used to control the operation of the host.

[0050] The oxygen cabin body 1 specifically includes a main shell 6, a door body 3, and an outward protruding shell 7. The door body 3 is installed on the main shell 6, and it can close the door opening formed in the main shell 6. The door body 3 may include a door body including a transparent observation portion, and a handle. The transparent observation portion may be made of transparent materials such as acrylic plate, tempered glass, etc. The door body 3 is connected to the main shell 6 through a hinge, and the door opening direction is inward. The main shell 6 is provided with a sealing ring at the inner edge of the door opening, such as a rubber sealing ring. When an oxygen-rich environment greater than one atmospheric pressure is formed inside the oxygen cabin body 1, the internal air pressure of the oxygen cabin body 1 can cause the door body 3 to be pressed against the sealing ring, effectively reducing or even avoiding the leakage of gas in the oxygen cabin body 1 through the door opening. A metal door frame 8, such as an aluminum alloy door frame, may be fixed to the edge of the door opening. The metal door frame 8 may compensate for the mechanical strength of the main shell 6 reduced by opening the door opening. Of course, the metal door frame 8 may also serve as a decoration.

[0051] The side wall of the main shell 6 is formed with a hole, and the protruding shell 7 is detachably installed at the hole. The seat 2 or bed can be partially extended into the protruding shell 7, and the protruding shell 7 can increase the space in the oxygen chamber body 1, especially the space required for the seat 2 or bed to be unfolded, and the space required for the user to lie on the unfolded seat 2 or bed, thereby improving the space utility rate of the oxygen chamber body 1.

[0052] Specifically, the protruding shell 7 includes a main body 9 protruding outward from the main shell 6 through the hole, and an annular fixing portion 10 formed by extending from the edge of the main body 9 in a direction away from the hole. The annular fixing portion 10 is arranged in the main shell 6 and directly or indirectly abuts against the inner wall of the main shell 6. When an oxygen-rich environment greater than one atmosphere is formed inside the oxygen chamber body 1, the internal air pressure of the oxygen chamber body 1 can cause the annular fixing portion 10 to directly or indirectly abut against the inner wall of the main shell 6, effectively reducing or even preventing the gas in the oxygen chamber body 1 from leaking through the hole. Preferably, a sealing ring, such as a rubber sealing ring, is also arranged between the annular fixing portion 10 and the inner wall of the main shell 6.

[0053] When the oxygen chamber body 1 is transported to the floor where the equipment is actually used by a passenger elevator, the protruding shell 7 can be removed first to reduce the external dimensions of the oxygen chamber body 1. The remaining components of the oxygen chamber body 1 are assembled on the main shell 6, and the oxygen chamber body 1 is transported to the floor where the equipment is actually used by a passenger elevator, and then moved to a designated location, and then the protruding shell 7 is assembled on the main shell 6. Of course, the external dimensions of the oxygen chamber body 1 with the protruding shell 7 removed should be smaller than the internal dimensions of the passenger elevator. The oxygen chamber body 1 can be assembled in the factory and tested for sealing. During transportation, only the protruding shell 7 needs to be removed, which greatly reduces the on-site assembly time.

[0054] In this embodiment, the number of the holes is two, and the two holes are arranged opposite to each other. Correspondingly, the number of the protruding shells 7 is two. Both of the two protruding shells 7 can provide space for the seat 2 or the bed to partially extend, or one of the protruding shells 7 can provide space for the seat 2 or the bed to partially extend, and the other protruding shell 7 can provide space for the user's feet to extend. The two protruding shells 7 increase the space required for the seat 2 or the bed to unfold, and the space required for the user to lie on the unfolded seat 2 or bed, greatly improving the space utility rate of the oxygen cabin body 1. In another embodiment, the number of the holes and the number of the protruding shells 7 can both be one.

[0055] See now Figure 5 , the main body 9 of the protruding shell 7 includes a spine 11 and two side portions 12. The spine 11 is arc-shaped, and its upper and lower ends are respectively connected to the inner periphery of the annular fixing portion 10, and the two side portions 12 are simultaneously connected to the corresponding side edges of the spine 11 and the inner periphery of the annular fixing portion 10. The protruding shell 7 adopts this structure to better adapt to the adjustment of the inclination angle of the backrest and leg rest of the seat 2, the space required for the adjustment of the inclination angle of the back bearing area and the leg bearing area of ​​the bed, and effectively reduce or even avoid the user's sense of oppression. It should be understood that the protruding shell 7 can also adopt other structures, which are not listed here one by one.

[0056] Return now Figures 1 to 4, the main shell 6 can be formed by splicing the first half shell 13 and the second half shell 14. Connectors such as bolts and nuts are used at the splicing line between the first half shell 13 and the second half shell 14 to connect the two together. A sealing ring, such as a rubber sealing ring, can also be arranged between the first half shell 13 and the second half shell 14 to improve the sealing performance. The splicing line between the first half shell 13 and the second half shell 14 is composed of two segments, and the virtual connecting line between the corresponding ends of the two segments passes through the hole, that is, the hole is composed of a half hole formed in the first half shell 13 and a half hole formed in the second half shell 14. The annular fixing part 10 is connected to the annular rigid ring 15 arranged on the outside of the main shell 6 through a connecting member to ensure that the protruding shell 7 is firmly installed at the hole and improve the mechanical strength of the area. Of course, the first half shell 13 and the second half shell 14 are provided with through holes for the connecting member to pass through, and the connecting member can be a bolt and nut. The annular rigid ring 15 can be a steel ring that matches the shape of the annular fixing part 10.

[0057] See also Figures 6 to 9 In this embodiment, the main shell 6 and the protruding shell 7 are both carbon fiber composite material shells, and the side wall is formed with a reinforcement portion 16 that bulges toward the inside of the main shell 6. Carbon fiber composite material is a new type of material that uses carbon fiber as a reinforcement and is combined with a matrix material by physical or chemical methods. The carbon fiber composite material can be a carbon fiber reinforced resin-based composite material, which is light in weight, has high strength and modulus, can be designed and manufactured as needed, and has a high degree of designability.

[0058] The reinforcement part 16 can improve the mechanical strength of the side wall. The number of the reinforcement parts 16 can be 3. The edge of the door opening formed in the first half shell 13 is fixed with a metal door frame 8 that improves the mechanical strength of the first half shell 13. Therefore, among the three reinforcement parts 16, one reinforcement part 16 is formed in the first half shell 13, and the remaining two reinforcement parts 16 are formed in the second half shell 14. It should be understood that the number of the reinforcement parts 16 can also be 2, 4, 5, 6 or a suitable number thereof. Specifically, the shape of each reinforcement part 16 can be generally rectangular ring, and its long side extends along the height direction of the main shell 6.

[0059] The oxygen cabin body 1 further includes a seal 17 arranged in the main shell 6 and covering the joint line between the first half shell 13 and the second half shell 14. The cross section of the seal 17 is U-shaped, with the opening facing the joint line between the first half shell 13 and the second half shell 14. The edge of the seal 17 is tightly connected to the inner wall surface of the first half shell 13 and the second half shell 14, for example, the gap between the seal 17 and the inner wall surface of the first half shell 13 and the second half shell 14 is sealed by using a sealant.

[0060] Return now Figures 2 to 3 , the main unit is arranged in the main unit room 4. The main unit room 4 is located outside the oxygen chamber body 1, and its side wall is fixedly connected to the side wall of the main shell 6. The main unit room 4 can be made of carbon fiber composite material, or can be made of metal material, or can be made of two or more materials. Specifically, the side wall of the main unit room 4 is in contact with the side wall of the second half shell 14, and is fixedly connected by bolts and nuts. The main unit room 4 in contact with the second half shell 14 can improve the mechanical strength of the second half shell 14.

[0061] The inner side of the oxygen chamber body 1 is provided with a decorative panel 18 and a floor 19. The decorative panel 18 and the floor 19 can completely or partially cover the pipes, circuits, electrical appliances, etc. laid or installed on the inner wall of the main shell 6, and the decorative panel 18 can be fixed on the inner wall of the first half shell 13 and the inner wall of the second half shell 14. The decorative panel 18 can be fixed with a table, hooks, etc. for placing or hanging the user's personal belongings.

[0062] The oxygen cabin may also include a metal frame 20 arranged below the floor 19, the metal frame 20 being fixed to the bottom of the main shell 6, and being used to carry the floor 19 and the seat 2 or bed arranged above the floor 19. Of course, the metal frame 20 also carries the user entering the oxygen cabin body 1.

[0063] In order to improve the entertainment of the oxygen chamber, the oxygen chamber may further include multimedia equipment arranged in the oxygen chamber body 1, such as a display, speakers, etc.

[0064] The oxygen chamber may further include a pressure relief device 21 disposed on the oxygen chamber body 1 . The pressure relief device 21 may be operated inside or outside the oxygen chamber body 1 to reduce the air pressure inside the oxygen chamber body 1 .

[0065] In the oxygen chamber of this embodiment, the main shell 6 and the protruding shell 7 of the oxygen chamber body 1 are made of carbon fiber composite materials, which are lighter than the oxygen chamber body 1 made of steel, and are easier to transport. When the oxygen chamber body 1 is transported to the floor where the equipment is actually used by a passenger elevator, only the protruding shell 7 can be removed first, and other components attached or fixed to the main shell 6 in the oxygen chamber body 1 can be transported together without disassembly. The sealing test can be performed on the oxygen chamber body 1 after the assembly is completed in the factory, which greatly reduces the on-site operation time. The seat 2 or bed can be partially extended into the protruding shell 7, and the protruding shell 7 can increase the space in the oxygen chamber body 1, especially the space required for the seat 2 or bed to be unfolded, and the space required for the user to lie on the unfolded seat 2 or bed, thereby improving the space utility rate of the oxygen chamber body 1.

[0066] See also Figures 10 to 12In another embodiment, the main shell 6 is made of two or more materials. Specifically, the first half shell 13 and the second half shell 14 each include a carbon fiber composite material shell 22, an aluminum alloy skeleton 23 closely attached to the inner side of the carbon fiber composite material shell 22, and a metal mesh 24 welded and fixed to the surface of the aluminum alloy skeleton 23 facing the carbon fiber composite material shell 22 and embedded in the matrix of the carbon fiber composite material shell 22. The combination of the carbon fiber composite material shell 22 and the aluminum alloy skeleton 23 enables the main shell 6 to meet both strength requirements and lightweight requirements.

[0067] In addition to the bonding between the contact surfaces of the carbon fiber composite material shell 22 and the aluminum alloy skeleton 23, the metal mesh 24 is also used to strengthen the connection between the carbon fiber composite material shell 22 and the aluminum alloy skeleton 23, so as to achieve a reliable connection between the carbon fiber composite material shell 22 and the aluminum alloy skeleton 23. Preferably, the carbon fiber composite material shell 22 is a shell made of carbon fiber reinforced resin-based composite material.

[0068] The aluminum alloy skeleton 23 may be composed of a grooved aluminum alloy 25, the groove of which faces the inside of the main shell 6, and the metal mesh 24 covers and is welded to the web of the grooved aluminum alloy 25. The grooved aluminum alloy 25 has high mechanical strength, and its two side wing plates may also be used as a fixing frame or a supporting frame for components installed inside the main shell 6, thereby avoiding the problem of stress concentration in the carbon fiber composite material shell 22 caused by mechanical fastening connection between the carbon fiber composite material shell 22 and the components installed inside the main shell 6.

[0069] See also Figures 13 to 15 , according to the oxygen cabin of the second embodiment of the present invention, it includes an oxygen cabin body 1, a seat 2 or a bed arranged in the oxygen cabin body 1, and a host for delivering oxygen to the oxygen cabin body 1 and adjusting the air pressure. The oxygen cabin body 1 is provided with a door body 3. When the door body 3 is in a locked state, the interior of the oxygen cabin body 1 is a closed space. The host can be composed of an oxygen concentrator, an air compressor, a temperature regulating device, a control circuit, etc., which is arranged in a host room 4. The oxygen concentrator is used to supply high-concentration oxygen, the air compressor is used to supply high-pressure air, the temperature regulating device is used to adjust the internal temperature of the oxygen cabin body 1, and the control circuit is used to control the operation of components such as the oxygen concentrator, the air compressor, and the temperature regulating device.

[0070] The oxygen cabin body 11 specifically includes a main shell 6, a door body 3, and an outward protruding shell 7. The door body 3 is installed on the main shell 6, and it can close the door opening formed in the main shell 6. The door body 3 may include a transparent door body and a handle. The door body may be made of transparent materials such as acrylic plate, tempered glass, etc. The door body 3 is connected to the main shell 6 through a hinge, and the door opening direction is inward. The main shell 6 is provided with a sealing ring, such as a rubber sealing ring, at the inner edge of the door opening. When an oxygen-rich environment greater than one atmospheric pressure is formed inside the oxygen cabin body 1, the internal air pressure of the oxygen cabin body 1 can cause the door body 3 to be pressed tightly against the sealing ring, effectively reducing or even avoiding the leakage of gas in the oxygen cabin body 1 through the door opening. A metal door frame 8, such as an aluminum alloy door frame, may be fixed to the edge of the door opening, and the metal door frame 8 may compensate for the mechanical strength of the main shell 6 reduced by opening the door opening. Ambient lights 30 may be provided at the edge of the metal door frame 8, such as light strips that can emit light of different colors, or light strips that emit light of a single color.

[0071] The side wall of the main shell 6 is formed with a hole, and the protruding shell 7 is detachably installed at the hole. The seat 2 or bed can be partially extended into the protruding shell 7, and the protruding shell 7 can increase the space in the oxygen chamber body 1, especially the space required for the seat 2 or bed to be unfolded, and the space required for the user to lie on the unfolded seat 2 or bed, thereby improving the space utility rate of the oxygen chamber body 1.

[0072] Specifically, the protruding shell 7 includes a main body 9 protruding outward from the main shell 6 through the hole, and an annular fixing portion 10 formed by extending from the edge of the main body 9 away from the hole. The annular fixing portion 10 is arranged in the main shell 6 and directly or indirectly abuts against the inner wall of the main shell 6. Fig.16 , the inner wall surface of the main body 9 of the protruding shell 7 is a semi-ellipsoidal surface. The protruding shell 7 adopts this structure to better adapt to the adjustment of the inclination angle of the backrest and leg support of the seat 2, the space required for the adjustment of the inclination angle of the back bearing area and the leg bearing area of ​​the bed, and effectively reduce or even avoid the user's sense of oppression.

[0073] See now Fig.17 and Fig.18In this embodiment, the annular fixing part 10 is fixedly connected to the main housing 6 by bolts and nuts, and a sealing ring 31 is arranged between the annular fixing part 10 and the inner side wall of the main housing 6. A first annular rigid ring 32 is arranged on the surface of the annular fixing part 10 facing away from the sealing ring 31, and a second annular rigid ring 33 is arranged on the surface of the main housing 6 facing away from the sealing ring 31. The heads of the nuts and bolts are respectively against one of the first annular rigid ring 32 and the second annular rigid ring 33. Both the first annular rigid ring 32 and the second annular rigid ring 33 can be steel rings adapted to the shape of the annular fixing part 10. The provision of the first annular rigid ring 32 and the second annular rigid ring 33 can effectively improve the mechanical strength of the edge area of ​​the hole and disperse the force of the bolts and nuts on the annular fixing part 10 and the main housing 6. A decorative cover 34 covering the head of the nut or bolt is arranged on the outer side of the main housing 6, and a light source 35 is arranged in the decorative cover 34, and the light emitted by the light source 35 can pass through the device cover.

[0074] When the oxygen chamber body 1 is transported to the floor where the equipment is actually used by a passenger elevator, the protruding shell 7 can be removed first to reduce the external dimensions of the oxygen chamber body 1. The remaining components of the oxygen chamber body 1 are assembled on the main shell 6, and the oxygen chamber body 1 is transported to the floor where the equipment is actually used by a passenger elevator, and then moved to a designated location, and then the protruding shell 7 is assembled on the main shell 6. Of course, the external dimensions of the oxygen chamber body 1 with the protruding shell 7 removed should be smaller than the internal dimensions of the passenger elevator. The oxygen chamber body 1 can be assembled in the factory and tested for sealing. During transportation, only the protruding shell 7 needs to be removed, which greatly reduces the on-site assembly time.

[0075] In this embodiment, the number of the holes is two, and the two holes are arranged opposite to each other. Accordingly, the number of the protruding shells 7 is two. Both of the two protruding shells 7 can provide space for the seat 2 or the bed to partially extend, or one of the protruding shells 7 can provide space for the seat 2 or the bed to partially extend, and the other protruding shell 7 can provide space for the user's feet to extend. The two protruding shells 7 increase the space required for the seat 2 or the bed to unfold, and the space required for the user to lie on the unfolded seat 2 or bed, greatly improving the space utility rate of the oxygen chamber body 1.

[0076] See now Fig.14 , Fig.19 , Fig. 20 and Fig.21 The main housing 6 can be formed by splicing a first half housing 13 and a second half housing 14. Connectors such as bolts and nuts are used at the splicing line between the first half housing 13 and the second half housing 14 to connect the two together. A sealing ring such as a rubber sealing ring can also be arranged between the first half housing 13 and the second half housing 14 to improve the sealing performance.

[0077] The splicing line of the first half shell 13 and the second half shell 14 is composed of two segments, and the virtual connecting line between the corresponding ends of the two segments passes through the hole, that is, the hole is composed of a half hole formed in the first half shell 13 and a half hole formed in the second half shell 14. The oxygen cabin body 1 also includes a seal 17 arranged in the main shell 6 and covering the splicing line of the first half shell 13 and the second half shell 14. The cross-section of the seal 17 is U-shaped, and the opening faces the splicing line of the first half shell 13 and the second half shell 14. The seal 17 can be fixed in the main shell 6 by screws, or by snap-fitting.

[0078] In this embodiment, the outer protruding shell 7 is made of carbon fiber composite material, and the main shell 6 is made of two or more materials. Fig.19 , Fig. 20 and Fig. 22 The first half shell 13 and the second half shell 14 both include a carbon fiber composite material shell 22 and an aluminum alloy skeleton 23 closely attached to the inner side of the carbon fiber composite material shell 22. The aluminum alloy skeleton 23 is composed of a groove-shaped aluminum alloy 25, the groove of which faces the inside of the main shell 6; the web 36 of the groove-shaped aluminum alloy 25 is formed with an extension 38 extending out of the outer side of the flange plate 37. The combination of the carbon fiber composite material shell 22 and the aluminum alloy skeleton 23 enables the main shell 6 to meet both strength requirements and lightweight requirements.

[0079] See now Fig.17 , the host is arranged in the host room 4. The host room 4 is located outside the oxygen chamber body 1, and its side wall is fixedly connected to the side wall of the main shell 6. The host room 4 can be made of carbon fiber composite material. The side wall of the host room 4 is fitted with the side wall of the second half shell 14 and is fixedly connected by bolts and nuts. The host room 4 fitted with the second half shell 14 can improve the mechanical strength of the second half shell 14.

[0080] In the oxygen chamber of this embodiment, the main structure of the oxygen chamber body 1, i.e., the protruding shell 7, the main shell 6, etc., is made of lightweight materials, which is easier to transport. When the oxygen chamber body 1 is transported to the floor where the equipment is actually used by a passenger elevator, only the protruding shell 7 can be removed first, and other components attached to or fixed inside the main shell 6 in the oxygen chamber body 1 can be transported together without disassembly. The sealing test can be performed on the oxygen chamber body 1 after it is assembled in the factory, which greatly reduces the on-site operation time.
