Abstract
Description
Technical Field
[0001] The utility model relates to a cabin structure of an oxygen chamber, belonging to the technical field of oxygen chambers. Background Art
[0002] A micro-hyperbaric oxygen chamber is an oxygen chamber that provides a hyperbaric oxygen inhalation method and is an oxygen therapy device with intelligent applications. It forms a micro-pressure environment harmless to the human body through shaping. Generally, a micro-hyperbaric environment of about 1.3 atmospheres is formed inside the chamber. Hyperbaric oxygen inhalation is different from ordinary oxygen inhalation. In the pressurized and oxygenated environment of the micro-hyperbaric oxygen chamber, the physically dissolved oxygen can be increased. The dissolved oxygen content can be increased by more than 5 times, which can assist the efficient absorption of oxygen, improve the oxygen content in the capillaries of the human body, provide sufficient oxygen to various organs of the brain, improve the state of body hypoxia, and play roles such as body recovery, regulation, and optimization. It is widely used in medical treatment, health care, and other fields; generally, hyperbaric oxygen chambers are huge in volume. Compared with hyperbaric oxygen chambers, micro-hyperbaric oxygen chambers are small in volume and can also select a suitable chamber size according to the number of users, such as single-person. Users can enter the chamber of the oxygen chamber for health care treatment. With the development of technology, micro-hyperbaric oxygen chambers are gradually used as equipment for health care and health preservation at home.
[0003] The structural forms of micro-hyperbaric oxygen chambers include soft-body type and hard-body type. The pressure inside the chamber of a micro-hyperbaric oxygen chamber is higher than the pressure outside the chamber. The soft-body type has poor shape stability, and the chamber will deform with the change of pressure. The poor pressure stability affects the pressurization and oxygenation effects of the oxygen chamber; while the chamber of the hard-body type micro-hyperbaric oxygen chamber generally adopts a layer of rigid structure. Even so, there will still be problems of deformation. Therefore, increasing the wall thickness of the chamber of the micro-hyperbaric oxygen chamber is used to avoid deformation. However, increasing the wall thickness will result in a large weight of the chamber, which is not convenient for movement. In addition, it will also increase the cost of the micro-hyperbaric oxygen chamber, which is not conducive to the use of the micro-hyperbaric oxygen chamber at home. Summary of the Invention
[0004] The utility model aims at the deficiencies existing in the prior art and provides a cabin structure of an oxygen chamber.
[0005] The technical solution for the utility model to solve the above technical problems is as follows: A cabin structure of an oxygen chamber includes a front wall and a rear wall. The front wall and / or the rear wall both include an inner layer, an outer layer, and a tie rod structure arranged between the inner layer and the outer layer. A cavity is formed between the inner layer and the outer layer. The tie rod structure is arranged in the cavity. The outer contour of the outer layer is connected to the inner layer. The tie rod structure includes a plurality of tie rods. The tie rods are arranged horizontally, vertically, longitudinally and horizontally, or obliquely. The inner side of the tie rod is connected to the inner layer.
[0006] The beneficial effects of the present utility model are as follows: The cabin structure adopts a double-layer structure of an inner layer and an outer layer, with a cavity formed between the inner layer and the outer layer. There is a tie rod structure on the inner layer. When the oxygen chamber is in use, the pressure on the inner wall of the cabin is greater than the external pressure. The inner layers of the front wall and the rear wall of the cabin will be stressed. The inner side of the tie rod is connected to the inner layer, increasing the pressure-bearing strength of the inner layer and reducing or even avoiding deformation of the inner layer due to stress. The outer layer can limit and constrain the outer side of the tie rod. Moreover, the outer boundary of the outer layer is connected to the inner layer, and can also act on the outer side of the tie rod to form an inward pulling force, further enhancing the pressure-bearing strength of the front wall and the rear wall of the oxygen chamber and reducing or even avoiding deformation of the cabin structure. In addition, the cabin structure is simple, without the need to increase the overall wall thickness of the cabin, with light weight, low cost, and better stability.
[0007] On the basis of the above technical solution, the present utility model can be further improved as follows.
[0008] Further, a gap is provided between the outer side of the tie rod and the outer layer.
[0009] The beneficial effect of adopting the above further solution is that the tie rod is installed on the inner layer and there is a gap between it and the outer layer. The gap is the space reserved for the deformation of the inner layer. When the pressure inside the cabin acts on the front wall or the rear wall, the tie rod structure provided on the inner layer can increase the pressure-bearing strength of the inner layer. When the oxygen chamber is in use, the internal pressure of the cabin is greater than the external pressure, and there is a cavity between the outer layer and the inner layer. The inner layers of the front wall and the rear wall of the cabin will be stressed and deform outward in an arched shape. The outer side of the tie rod will touch the inner surface of the outer layer, and the boundary of the outer layer is connected to the inner layer, which can play a role in limiting and constraining the tie rod. By forming an inward pulling force on the tie rod through the outer layer, it can hinder the further outward expansion of the inner layer and the tie rod, and can reduce or even avoid deformation of the front wall or the rear wall of the cabin.
[0010] Further, the outer side of the tie rod is connected to the outer layer.
[0011] The beneficial effect of adopting the above further solution is that, of course, it is also possible to choose to connect the outer side of the tie rod to the outer layer according to the pressure situation inside the cabin. The inner layer, the outer layer, and the tie rod structure supporting between the inner layer and the outer layer form an overall cabin wall structure, which can enhance the pressure-bearing strength of the front wall or the rear wall of the cabin and reduce or even avoid the situation of deformation of the front wall or the rear wall of the cabin.
[0012] Further, a connecting portion connected to the inner layer is provided on the edge of the outer layer. The inner layer is a planar structure, and the connecting portion is formed by the edge of the outer layer extending towards the edge of the inner layer.
[0013] The beneficial effect of adopting the above further solution is that the inner layer adopts a planar structure, and the outer boundary of the outer layer bends and extends inward to form a connecting portion to connect with the connecting position of the inner layer, so that the outer layer can act on the tie rod and form a pulling force during the use of the oxygen chamber, increasing the pressure-bearing strength of the cabin wall.
[0014] Furthermore, the connecting part is an arc structure, and the outer contour of the end of the pull rod is consistent with the shape of the connecting part.
[0015] The beneficial effect of adopting the above further solution is that the outer layer can be bent inward with an arc-shaped smooth transition, which is convenient for processing and has a beautiful appearance.
[0016] Furthermore, multiple pull rods are horizontally arranged as cross bars, and multiple pull rods are vertically arranged as longitudinal bars. The cross bars and the longitudinal bars are vertically and intersectingly arranged between the inner layer and the outer layer.
[0017] The beneficial effect of adopting the above further solution is that multiple pull rods can adopt a criss-cross layout. The inner sides of the pull rods are installed on the outer surface of the inner layer, increasing the pressure-bearing strength of the cabin wall.
[0018] Furthermore, the outer layer is welded to the inner layer.
[0019] The beneficial effect of adopting the above further solution is that the outer boundary of the outer layer and the inner layer are connected by welding, which is convenient and firm.
[0020] Furthermore, the pull rod structure is welded on the outer surface of the inner layer.
[0021] The beneficial effect of adopting the above further solution is that the pull rod structure can be connected to the inner layer by welding, which is convenient and stable.
[0022] Furthermore, it further includes a peripheral wall arranged between the front wall and the rear wall. The peripheral wall includes an inner wall layer, an outer wall layer, and a vertical rod structure arranged between the inner wall layer and the outer wall layer.
[0023] The beneficial effect of adopting the above further solution is that the peripheral wall of the oxygen chamber also adopts a double-layer structure design of an inner wall layer, a vertical rod structure, and an outer wall layer, increasing the pressure-bearing performance of the peripheral wall of the chamber body and avoiding the deformation of the peripheral wall of the chamber body due to the pressure inside the chamber.
[0024] Furthermore, the vertical rod structure includes multiple vertically arranged vertical rods. The vertical rods are arranged along the circumferential direction of the peripheral wall, and the inner sides of the vertical rods are connected to the inner wall layer.
[0025] The beneficial effect of adopting the above further solution is that when the oxygen chamber is a micro-chamber structure, such as a single-person accommodation, the thickness of the chamber body is not large, the pressure on the peripheral wall of the oxygen chamber is less than the pressure on the front wall and the rear wall. The peripheral wall of the oxygen chamber can meet the requirements of the pressure-bearing strength of the peripheral wall by adopting vertically arranged vertical rods; at the same time, the vertical rods are not arranged in a criss-cross manner, which can reduce costs, reduce the weight of the chamber body, and facilitate the movement of the oxygen chamber.
[0026] Furthermore, there is a gap between the outer side of the vertical rod and the outer wall layer; or the outer side of the vertical rod is connected to the outer wall layer.
[0027] The beneficial effect of adopting the above further solution is that it is possible to select whether the vertical rod is only connected to the inner wall layer or is connected to both the inner wall layer and the outer wall layer according to the pressure inside the oxygen chamber, so as to meet the pressure-bearing requirements of the peripheral wall of the chamber body and avoid deformation of the peripheral wall due to the pressure inside the chamber.

[0036] The principles and features of the present invention will be described below in conjunction with examples. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.
[0037] Example 1, as Figures 1-7 shown, a chamber body structure of an oxygen chamber includes a front wall 1 and a rear wall 2. The front wall 1 and / or the rear wall 2 both include an inner layer 4, an outer layer 5, and a tie rod structure 6 provided between the inner layer 4 and the outer layer 5. A cavity is formed between the inner layer 4 and the outer layer 5. The tie rod structure 6 is arranged in the cavity. The outer contour of the outer layer 5 is connected to the inner layer 4. The tie rod structure 6 includes a plurality of tie rods. The tie rods are arranged horizontally, vertically, longitudinally and horizontally, or obliquely. The inner side of the tie rod is connected to the outer surface of the inner layer 4.
[0038] A gap 7 is provided between the outer side of the pull rod and the inner surface of the outer layer 5. The pull rod is installed on the inner layer 4 and there is a gap 7 between it and the outer layer 5. The gap 7 is the space reserved for the deformation of the inner layer 4. When the pressure inside the cabin acts on the front wall 1 or the rear wall 2, the pull rod structure 6 provided on the inner layer 4 can increase the pressure-bearing strength of the inner layer 4. When the oxygen cabin is in use, the internal pressure of the cabin is greater than the external pressure, there is a cavity between the outer layer 5 and the inner layer 4. When the inner layer 4 of the front wall 1 and the rear wall 2 of the cabin is stressed, it will arch outwards and deform. The outer side of the pull rod will touch the inner surface of the outer layer 5, and the boundary of the outer layer 5 is connected to the inner layer 4, which can play a role of limiting and restraining the pull rod. By forming an inward pulling force on the pull rod through the outer layer 5, it hinders the inner layer 4 and the pull rod from expanding outwards further, and can reduce or even avoid the deformation of the front wall 1 or the rear wall 2 of the cabin.
[0039] A connecting part 51 for connecting with the inner layer 4 is provided on the edge part of the outer layer 5. The inner layer 4 is a planar structure, and the connecting part 51 is formed by extending from the edge part of the outer layer 5 towards the edge part of the inner layer 4. The inner layer 4 adopts a planar structure, and the outer boundary of the outer layer 5 bends inwards and extends to form the connection position with the inner layer 4 for connection, so that the outer layer 5 can act on the pull rod and form a pulling force during the use of the oxygen cabin, increasing the pressure-bearing strength of the cabin wall.
[0040] The connecting part 51 is an arc-shaped structure, and the outer contour of the end part of the pull rod is the same as the shape of the connecting part 51. The inward bending of the outer layer 5 can adopt an arc-shaped smooth transition, which is convenient for processing and has a beautiful appearance.
[0041] Multiple pull rods are horizontally arranged as cross bars 61, and multiple pull rods are vertically arranged as longitudinal bars 62. The cross bars 61 and the longitudinal bars 62 are vertically and intersectingly arranged between the inner layer 4 and the outer layer 5. Multiple pull rods can adopt a criss-cross layout, and the inner sides of the pull rods are installed on the outer surface of the inner layer 4 to increase the pressure-bearing strength of the cabin wall.
[0042] The outer layer 5 and the inner layer 4 are welded. The outer boundary of the outer layer 5 and the inner layer 4 are connected by welding, which is convenient and firm.
[0043] The pull rod structure 6 is welded on the outer surface of the inner layer 4. The pull rod structure 6 can be connected to the inner layer 4 by welding, which is convenient and stable.
[0044] It also includes a peripheral wall 3 provided between the front wall 1 and the rear wall 2. The peripheral wall 3 includes an inner wall layer 8, an outer wall layer 9 and a vertical rod 10 structure provided between the inner wall layer 8 and the outer wall layer 9. The peripheral wall 3 of the cabin body of the oxygen cabin also adopts a double-layer structure design of the inner wall layer 8, the vertical rod 10 structure and the outer wall layer 9, increasing the pressure-bearing performance of the peripheral wall 3 of the cabin body and avoiding the deformation of the peripheral wall 3 of the cabin body due to the pressure inside the cabin.
[0045] The structure of the vertical rods 10 includes a plurality of vertically arranged vertical rods 10. The vertical rods 10 are arranged along the circumferential direction of the outer peripheral wall 3, and the inner sides of the vertical rods 10 are connected to the inner wall layer 8. When the oxygen chamber is a micro-chamber structure, such as a single-person accommodating chamber with a small thickness, the pressure on the outer peripheral wall 3 of the oxygen chamber is less than the pressure on the front wall 1 and the rear wall 2. The outer peripheral wall 3 of the oxygen chamber can meet the requirements of the bearing strength of the outer peripheral wall 3 by using vertically arranged vertical rods 10; at the same time, since the vertical rods 10 are not arranged in a criss-cross manner, the cost can be reduced, the weight of the chamber can be reduced, and the movement of the oxygen chamber can be facilitated.
[0046] The outer sides of the vertical rods 10 are connected to the outer wall layer 9. According to the pressure inside the oxygen chamber and the pressure that the outer peripheral wall 3 needs to bear, it can be selected to connect the inner sides of the vertical rods 10 to the inner wall layer 8 and the outer sides of the vertical rods 10 to the outer wall layer 9, so as to meet the bearing requirements of the outer peripheral wall 3 of the chamber and prevent the outer peripheral wall 3 from deforming due to the pressure inside the chamber.
[0047] Embodiment 2: A gap 7 is provided between the outer sides of the vertical rods 10 and the outer wall layer 9. According to the pressure inside the oxygen chamber and the pressure that the outer peripheral wall 3 needs to bear, it can be selected to connect the inner sides of the vertical rods 10 to the inner wall layer 8, and there is no connection between the outer sides of the vertical rods 10 and the outer wall layer 9, but a gap 7 is reserved, so as to meet the bearing requirements of the outer peripheral wall 3 of the chamber and prevent the outer peripheral wall 3 from deforming due to the pressure inside the chamber. The remaining structure is the same as that of Embodiment 1, so it will not be described in detail here.
[0048] Embodiment 3: The outer sides of the tie rods are connected to the inner surface of the outer layer 5. According to the pressure inside the oxygen chamber and the pressure that the front wall 1 and the rear wall 2 of the chamber need to bear, it is selected to connect the inner sides of the tie rods to the outer surface of the inner layer 4 and the outer sides of the tie rods to the inner surface of the outer layer 5. The inner layer 4, the outer layer 5 and a plurality of tie rods form an integral chamber wall structure, which can improve the bearing strength of the front wall 1 or the rear wall 2 of the chamber and reduce or even prevent the front wall 1 or the rear wall 2 of the chamber from deforming. The structure is the same as that of Embodiment 1, so it will not be described in detail here.
[0049] The cabin structure of the oxygen chamber includes a front wall, a rear wall, and an outer peripheral wall disposed between the front wall and the rear wall. The thickness of the cabin structure applicable to a single person is relatively thin, the pressure-bearing surface of the outer peripheral wall 3 of the cabin is small, and the force is relatively small compared with the front wall and the rear wall. Therefore, the outer peripheral wall can adopt the design of an inner wall layer 8, an outer wall layer 9, and a vertical rod 10 structure, which can not only meet the requirement of the outer peripheral wall 3 to bear the pressure inside the cabin, reduce or even avoid the deformation caused by the force on the outer peripheral wall, but also reduce the number of components inside the outer peripheral wall, reduce costs, and reduce the weight of the cabin. For the front wall 1 and the rear wall 2 of the cabin structure, the pressure-bearing surfaces of the front wall and the rear wall are large, and the force is relatively large compared with the outer peripheral wall. Therefore, both the front wall and the rear wall can adopt a double-layer structure of an inner layer 4 and an outer layer 5. A cavity is formed between the inner layer 4 and the outer layer 5, and a plurality of tie rods are also arranged in the cavity. The tie rods include a plurality of longitudinal rods and transverse rods. The transverse rods and the longitudinal rods intersect vertically and are welded on the outer surface of the inner layer of the front wall or the rear wall, which can enhance the pressure-bearing strength of the inner layer of the front wall and the rear wall. The periphery of the outer layer extends in an arc structure to the inner layer boundary and is welded to the inner layer. When the oxygen chamber is in use, the pressure inside the inner wall of the cabin is greater than the external pressure. The inner layers 4 of the front wall 1 and the rear wall 2 of the cabin are respectively stressed. The inner layer with the tie rod structure has a large pressure-bearing strength and is not easily deformed. If it is deformed and arched outward due to the large pressure inside the cabin, the outer layer 5 can also act on the outside of the tie rod and limit and restrain the outside of the tie rod. At the same time, because the outer boundary of the outer layer 5 is connected to the inner layer 4, it can also act on the outside of the tie rod to form an inward pulling force. The structures of the front wall 1, the rear wall 2, and the outer peripheral wall of the cabin structure of the oxygen chamber of the present invention are simple, have a large pressure-bearing strength, can reduce or even avoid the deformation of the cabin structure when the oxygen chamber is in use, are lighter in weight compared with increasing the wall thickness as a whole, are convenient to move, and can be more widely used in families.
[0050] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
