[0002] An oxygen concentrator is a machine that produces oxygen. Its principle is based on air separation technology, especially adsorption-type oxygen concentrators, which utilize the adsorption properties of molecular sieves.

This type of oxygen concentrator produces oxygen rapidly and at a high concentration, making it suitable for oxygen therapy and health maintenance for various groups of people.

[0003] In traditional adsorption oxygen generators, the molecular sieve needs to be replaced after it fails to adsorb. However, the existing sealed molecular sieve adsorption towers are inconvenient to disassemble and assemble, and each replacement of the molecular sieve takes a long time, making it inconvenient to replace the molecular sieve quickly.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-7 An adsorption-type oxygen generator includes a molecular sieve adsorption tower 2 disposed inside a housing 1, and an installation assembly 3 and a clamping assembly 4 for quick installation of the molecular sieve adsorption tower 2. The molecular sieve adsorption tower 2 includes two cylinders 201 for storing molecular sieves, an upper cover 202 that seals the top of the two cylinders 201, and a lower cover 203 that seals the bottom of the two cylinders 201. The two cylinders 201 are fixed to the upper surface of the lower cover 203. The surfaces of the upper cover 202 and the lower cover 203 are respectively provided with sealing interfaces that communicate with the two cylinders 201. The sealing interfaces are used to connect hoses for the transmission of air and oxygen.

[0028] The mounting assembly 3 includes two guide rails 301 fixed to the bottom of the housing 1 and a sliding plate 302 that slides on the surface of the two guide rails 301. A positioning ring 303 that cooperates with the lower cover 203 is fixed on the upper surface of the sliding plate 302. An opening for removing the molecular sieve adsorption tower 2 from the housing 1 is provided on the back of the housing 1. A first cover plate is hinged to the side of the opening.

[0029] It is understandable that by setting the positioning ring 303, the lower cover 203 of the molecular sieve adsorption tower 2 can be positioned, and the sliding plate 302 can slide on the surface of the two guide rails 301, so as to facilitate the pulling of the molecular sieve adsorption tower 2 out of the shell 1 and facilitate the replacement of the molecular sieve.

[0030] Specifically, the pressing assembly 4 includes two guide rods 402 fixed to the top of the housing 1 and a pressing frame 401 sliding on the surfaces of the two guide rods 402. The pressing frame 401 includes two pressure rods sliding on the surfaces of the two guide rods 402 and a connecting plate fixing the surfaces of the two pressure rods. Both pressure rods are fixed to the upper surface of the cover 202 and correspond to the two cylinders 201 respectively. A threaded sleeve 403 is fixed to the upper surface of the pressing frame 401. A groove 405 is provided on the upper surface of the housing 1. A threaded post 404 is rotatably provided at the bottom of the groove 405. The threaded post 404 is threadedly connected to the inside of the threaded sleeve 403. The threaded sleeve 403 and the threaded post 404 are located between the two pressure rods. A handle is fixed to the upper end of the threaded post 404. The handle is located inside the groove 405. A second cover plate for closing the groove 405 is hinged to the upper surface of the housing 1.

[0031] Understandably, after the molecular sieve adsorption tower 2 is pushed into the housing 1 by the sliding plate 302, the rotating handle is turned, causing the threaded column 404 to drive the threaded sleeve 403 to move downwards. This causes the pressing frame 401 to slide downwards on the surfaces of the two guide rods 402, allowing the two pressing rods to simultaneously press the upper cover 202 of the two sealed cylinders 201, thus sealing the upper ends of the two cylinders 201 and facilitating the installation of the molecular sieve adsorption tower 2. When it is necessary to remove the molecular sieve adsorption tower 2 from the housing 1, the threaded column 404 drives the pressing frame 401 to rise, causing the upper cover 202 to detach from the cylinder 201, making it easy to pull the cylinder 201 out of the housing 1 by the sliding plate 302, facilitating the replacement of the molecular sieve. The groove 405 is designed to conceal the rotating handle, preventing accidental contact with the rotating handle from causing the upper cover 202 to loosen.

[0032] Specifically, the bottom of the upper cover 202 is provided with a positioning component 5 to facilitate the insertion of the upper cover 202 into the two cylinders 201. The positioning component 5 includes multiple positioning rods 501 fixed on the lower surface of the upper cover 202 and a connecting block 503 fixed between the two cylinders 201. The surface of the connecting block 503 is provided with multiple positioning holes 502 that cooperate with the positioning rods 501. The lower end of the positioning rod 501 is conical, and the top of the positioning hole 502 is provided with an outwardly expanding flared mouth. A partition 7 is vertically fixed inside the shell 1. The partition 7 is located on the side of the molecular sieve adsorption tower 2 away from the opening. An elastic plate 504 for positioning the slide plate 302 is fixed on the side of the partition 7 near the slide plate 302. The elastic plate 504 is arc-shaped.

[0033] Understandably, when the clamping assembly 4 drives the upper cover 202 to seal the upper end of the cylinder 201, the upper cover 202 first drives multiple positioning rods 501 to insert into multiple positioning holes 502. This positions the cylinder 201 and the upper cover 202 relative to each other, facilitating the sealing of the cylinder 201 by inserting the upper cover 202 into the upper end of the cylinder 201. By setting a conical and flared shape, the positioning rods 501 can be inserted into the positioning holes 502 even if there is a deviation in the position of the cylinder 201. The elastic plate 504 facilitates the initial positioning of the sliding plate 302 entering the housing 1. Since the upper cover 202 needs to be precisely aligned when inserted into the cylinder 201, and the parts... Errors can occur during production and assembly. If a rigid connection is used to position the slide plate 302, when there is a deviation between the upper cover 202 and the cylinder 201, the positioning rod 501, after being inserted into the positioning hole 502, cannot move the cylinder 201 and the slide plate 302 to correct the deviation, thus affecting the sealing effect of the upper cover 202 on the cylinder 201. Therefore, the elastic plate 504 is used to initially position the slide plate 302 and the cylinder 201. When the positioning rod 501 is inserted into the positioning hole 502, the positioning rod 501 can move the cylinder 201 and the slide plate 302 on the surface of the guide rail 301, thereby correcting the deviation between the upper cover 202 and the cylinder 201 and avoiding affecting the sealing effect.

[0034] Specifically, a combing assembly 6 for combing the flexible tube connected to the lower cover 203 is provided on the side of the partition 7 near the molecular sieve adsorption tower 2. The combing assembly 6 includes a movable plate 601 that slides laterally on the surface of the partition 7 and a plurality of first connecting rings 603 fixed on the surface of the movable plate 601. The plurality of first connecting rings 603 are arranged in a fan shape on the surface of the movable plate 601. The height of the movable plate 601 is higher than the sealing interface of the lower cover 203. A spring 602 is fixed on the side of the movable plate 601 to move the movable plate 601 away from the sealing interface of the lower cover 203. The plurality of first connecting rings 603 are all sleeved on the surface of the flexible tube. A second connecting ring 604 is fixed in the middle of the partition 7 at a position corresponding to the sealing interface. The height of the second connecting ring 604 is higher than the height of the movable plate 601 and fixed on the surface of the flexible tube. The second connecting ring 604 is located at the end of the flexible tube away from the sealing interface.

[0035] Understandably, since the sliding plate 302 needs a relatively long flexible tube to provide a certain distance of movement when it moves the molecular sieve adsorption tower 2 out of the housing 1, in order to avoid the phenomenon of excessive bending of the flexible tube and blockage after the molecular sieve adsorption tower 2 enters the housing 1, the flexible tube is inserted into the surface of multiple first connecting rings 603, so that the spring 602 pushes the moving plate 601 away from the sealing interface. With the multiple first connecting rings 603 arranged in a fan shape, the flexible tube is bent in an arc shape, which automatically straightens the flexible tube and prevents the flexible tube from bending and causing blockage. When the molecular sieve adsorption tower 2 moves outward, the flexible tube is pulled, which drives the moving plate 601 to slide towards the sealing interface. At the same time, the flexible tube slides on the surface of multiple first connecting rings 603, straightening the bent flexible tube and providing a certain distance of movement for the molecular sieve adsorption tower 2.

[0036] In this invention, when the molecular sieve needs to be replaced, the second cover plate sealing the groove 405 is opened, the handle is rotated to move the pressing frame 401 upward, separating the upper cover 202 from the cylinder 201. Then, the sliding plate 302 is pulled to pull the cylinder 201 out of the housing 1. While the cylinder 201 is moving, the bent hose is straightened to provide a distance for the movement of the molecular sieve adsorption tower 2. After the cylinder 201 has safely moved out of the housing 1, the hose is removed from the sealing interface surface, and the cylinder 201 is taken out from the surface of the positioning ring 303. The molecular sieve inside the cylinder 201 is replaced. After replacement, it is placed back on the surface of the sliding plate 302 and positioned by the positioning ring 303. The slide plate 302 and the cylinder 201 are pushed into the housing 1 and initially positioned by the elastic plate 504, causing the top cover 202 to move down. This causes multiple positioning rods 501 to be inserted into multiple positioning holes 502, positioning the cylinder 201 and the top cover 202 relative to each other. This facilitates the insertion of the top cover 202 into the upper end of the cylinder 201 to seal it. The hose is bent in an arc shape by multiple first connecting rings 603, which can prevent the hose from bending and causing blockage. In this way, the molecular sieve adsorption tower 2 can be quickly removed from or installed back into the housing 1, improving the efficiency of molecular sieve replacement.
