[0002] Hyperbaric oxygen therapy is a medical measure taken to treat diseases under conditions higher than air pressure. It needs to be treated in a special hyperbaric oxygen chamber. It is a medical measure that can effectively improve, alleviate and correct the body's hypoxia. Generally, in a hyperbaric oxygen chamber, a PSA oxygen generator uses compressed air as a raw material to separate oxygen, thereby providing high oxygen for the oxygen mask in the hyperbaric oxygen chamber. The compressed air in the air pressurized oxygen chamber is used to establish a high-pressure environment to treat hypoxic diseases, and compressed air is used to improve the environmental quality in the air pressurized oxygen chamber.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention provides an air purification and filtration system for a hyperbaric oxygen chamber, which solves the problem that the existing air purification and filtration system for a hyperbaric oxygen chamber is difficult to perform repeated circulation filtration through a single-layer filter screen when in use. It is convenient to drive the rotating disk to rotate intermittently and switch the position of the switching cylinder to achieve control of air delivery.

The collection chambers 20 are alternately distributed with the driving grooves 14. An input groove 21 connected to the filter cartridge 9 is arranged on the side of the collecting chamber 20. A threaded rod 22 coaxially threadedly connected to the top of the driving column 10 is fixedly connected to the bottom of the top cover 19.

[0035] The switching mechanism 5 also includes an intake pipe 23 and an exhaust pipe 24 fixedly mounted on the fixing ring 3, the intake pipe 23 is provided with a control valve 42, a delivery pipe 25 connected to the switching cylinder 7 is provided on the bottom plate 6, a first pipe 26 capable of being connected to the intake pipe 23 and the delivery pipe 25 is provided on the fixing ring 3, a second pipe 27 capable of being connected to the exhaust pipe 24 and the delivery pipe 25 is provided on the fixing ring 3, one end of the exhaust pipe 24 is connected to the intake end of the processing tank 2, and a driving member 28 for driving the rotating disk 4 and the driving column 10 to rotate is provided in the machine body 1.

[0036] The driving member 28 includes a driving motor 29 fixedly installed in the body 1, and the model of the driving motor 29 is preferably Y80M1-2. The bottom end of the driving column 10 is coaxially fixedly connected with a driving shaft 30, which passes through the bottom plate 6 and is rotatably connected to the bottom plate 6. The bottom end of the driving shaft 30 is coaxially fixedly connected with a driving disk 31, and the output end of the driving motor 29 is fixedly connected with a driving frame 32, and a driving ring 33 is fixedly connected to the driving frame 32. The bottom of the rotating disk 4 is coaxially fixedly connected with a fixed disk 34, and a control member 35 for controlling the rotation state of the driving disk 31 and the fixed disk 34 is provided on the driving ring 33. An electric clamp 41 for limiting the position of the rotating disk 4 is provided in the body 1.

[0037] The control member 35 includes a plurality of groups of first bevel gear blocks 36 uniformly and fixedly mounted on the outer wall of the driving disk 31; the outer wall of the driving ring 33 is rotatably connected to a plurality of groups of first ratchet teeth 37 via a clockwork shaft, and the tips of the first ratchet teeth 37 can push against the side surfaces of the first bevel gear blocks 36; the inner wall of the driving ring 33 is uniformly and fixedly connected to a plurality of groups of second bevel gear blocks 38; the outer wall of the fixed disk 34 is rotatably connected to a plurality of groups of second ratchet teeth 39 via a clockwork shaft, and the tips of the second ratchet teeth 39 can push against the side surfaces of the second bevel gear blocks 38.

[0038] In this implementation plan, it is stipulated that Figure 3 The middle driving motor 29 drives the driving frame 32 to rotate clockwise for positive rotation and counterclockwise for reverse rotation. The control valve 42 is opened to input the external gas into the intake pipe 23, and then input it into the switching cylinder 7 through the first pipeline 26 and the delivery pipe 25. The control valve 42 is closed. When the driving frame 32 rotates forward, it will drive the second bevel gear block 38 to push the tip of the second ratchet 39, so that the fixed disk 34 drives the rotating disk 4 to rotate. At this time, the limit of the rotating disk 4 is released by the electric clamp block 41. When the rotating disk 4 switches the set angle, the rotating disk 4 is limited again by the electric clamp block 41. At the same time, the driving motor 29 is switched to drive the driving frame 32 to rotate in the direction of rotation to achieve the switching of the switching cylinder 7 position.

[0039] When the driving frame 32 rotates in the reverse direction, the tip of the first ratchet 37 on the driving ring 33 will be driven to contact and mesh with the side of the first bevel gear block 36, thereby driving the driving plate 31 and the driving shaft 30 to rotate. The driving shaft 30 drives the driving column 10 to rotate at a high speed. At this time, the driving plate 11 is pushed by the first spring 13, and the top end always contacts the inner wall of the filter cartridge 9. Since the driving column 10 and the filter cartridge 9 are not coaxial, as shown in the attached Figure 8 As shown, during the counterclockwise rotation of the driving plate 11, suction force is generated in the left area of ​​the inner wall of the filter cylinder 9, and the air in the switching cylinder 7 is drawn from the left filter cylinder 9 into the inside of the filter cylinder 9 to achieve the first layer of filtration. During the rotation of the driving plate 11 to the right area, the air in the filter cylinder 9 is compressed and output to the switching cylinder 7 through the right filter cylinder 9 for secondary filtration, and then it is drawn in again through the filter cylinder 9 in the left area. This reciprocating process achieves the purpose of multiple cycle filtration of a single group of filter cylinders 9. While the filtration effect is higher, the amount of filter screen used is also reduced. The dust in the air is relatively fine and will remain in the fibers inside the filter cylinder 9 for collection, and only a small amount will remain on the surface.

[0040] By rotating the driving plate 11, a small amount of dust remaining on the inner wall of the filter cartridge 9 can be scraped off and pushed to the right area, and in the area where the driving plate 11 is close to the compression limit position, the dust is completely pushed into the input slot 21. The dust flows with the air through the gaps between the multiple sets of inclined plates 40 and flows into the collecting chamber 20 for storage. The inclined plate 40 reduces the outward flow rate of the air in the collecting chamber 20, reduces the reflux of dust in the collecting chamber 20, and the top cover 19 at the top is rotated to open the dust in the collecting chamber 20.

[0041] It is worth noting that: during installation, first install the filter cartridge 9, the mounting ring 16, and the support rod 17 into the switching cylinder 7, so that the support rod 17 is vertically inserted into the bottom plate 6 for fixed position, and then the threaded cover 18 is screwed to the top of the switching cylinder 7 to complete the fixation, and finally the threaded rod 22 is screwed into the driving column 10, and the top cover 19 closes the top of the collecting chamber 20 to complete the installation process. Conversely, the filter cartridge 9 can also be disassembled and maintained. When the threaded cover 18 is tightened, the circular hole in the middle of the threaded cover 18 is located at the top of the driving column 10. At this time, the top cover 19 can be covered and rotated.

[0042] When the switching cylinder 7 rotates and switches to a position close to one side of the processing tank 2, the bottom end of the delivery pipe 25 is connected to the second pipe 27, so that the filtered air in the switching cylinder 7 can be pumped into the processing tank 2 for subsequent disinfection and pressurization operations. After that, the switching cylinder 7 is rotated again to the position where the delivery pipe 25 is connected to the first pipe 26 for vacuum operation, and the high-pressure oxygen in the processing tank 2 can be continuously used subsequently.

[0043] During the switching process, the device can intermittently input a set amount of air into the equipment, and fully circulate and filter the set amount of air, thereby increasing the air treatment time and avoiding the situation where the air passes through the filter quickly and the treatment effect is not thorough enough. At the same time, the device can ensure the stability of the air treatment process through switching and avoid the problem of too long treatment time affecting the gas transmission efficiency.

[0044] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
