[0002] Molecular sieve oxygen concentrators use the adsorption properties of molecular sieves to adsorb nitrogen in the air and thus separate oxygen. However, during long-term use of the oxygen concentrator, the molecular sieve pores will be blocked by impurities, or its structure will change due to physical and chemical reactions, resulting in a decrease in adsorption performance. Therefore, the molecular sieve needs to be replaced in time to ensure the stable operation of the oxygen concentrator. When replacing the molecular sieve, it is necessary to use a screwdriver to dismantle the outer casing of the oxygen concentrator, then remove the pipes and lines connecting the molecular sieve components and use appropriate tools to remove the old molecular sieve from the fixed position, and then replace the molecular sieve particles. At the same time, the removed screws and parts need to be kept. The replacement process is complicated and requires certain professional technical knowledge and operating experience, including familiarity with the internal structure of the oxygen concentrator, correct disassembly and installation procedures, etc. Otherwise, the equipment is easily damaged.

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1

[0032] Reference Figures 1-9 , which is the first embodiment of the present utility model, provides a medical oxygen concentrator, which includes an installation assembly 200, including a cover plate 201a, a molecular sieve cylinder 201b, a rotating column 201c, a fixed block 201d and a slider 201e. The molecular sieve cylinder 201b is arranged below the cover plate 201a, the rotating column 201c is located on one side of the molecular sieve cylinder 201b, the fixed block 201d is fixed on the rotating column 201c, a through groove 201a-1 is opened in the middle of the cover plate 201a, the rotating column 201c and the fixed block 201d can slide in the through groove 201a-1, and the slider 201e is fixed to the cover plate 201a.

[0033] The extrusion assembly 300 is arranged on one side of the installation assembly 200, and includes an extrusion plate 301a, a sliding plate 301b, a sliding block 301c, a push block 301d and a push plate 301e. The extrusion plate 301a is arranged in the molecular sieve cylinder 201b, and the two ends of the sliding plate 301b are respectively in contact with the bottom of the cover plate 201a and the extrusion plate 301a, the sliding block 301c is located on one side of the sliding plate 301b, the sliding block 301c is fixed to one side of the sliding plate 301b, and the push block 301d is fixed to one side of the sliding block 301c. The cover plate 201a is provided with a sliding groove 201a-2, and the push block 301d is slidably connected to the sliding groove 201a-2. The push plate 301e is arranged on one side of the push block 301d, and the cover plate 201a is provided with a card slot 201a-3, and the push plate 301e is slidably connected to the card slot 201a-3.

[0034] There are two molecular sieve cylinders 201b, and the rotating column 201c is set between the two molecular sieve cylinders 201b. By setting the top of the slider 201e to be inclined, it is convenient for the fixed block 201d to rotate and squeeze the slider 201e.

[0035] The rotating column 201c is connected to the bearing of the box 102. The cooperation of the rotating column 201c, the fixed block 201d and the slider 201e is used to ensure that the cover 201a and the molecular sieve cylinder 201b can be tightly combined, thereby ensuring the sealing of the molecular sieve and avoiding the decrease in oxygen concentration due to insufficient sealing.

[0036] When the molecular sieve particles need to be replaced, the rotating column 201c is rotated to drive the fixed block 201d to rotate, so that the positions of the fixed block 201d and the rotating column 201c correspond to the position of the through groove 201a-1, and the fixation of the cover plate 201a and the box body 102 is released. The cover plate 201a can be separated from the box body 102, and the box body 102 can be turned upside down to pour out the old molecular sieve particles.

[0037] There are two extrusion plates 301a, which are located in the two molecular sieve cylinders 201b and are used to extrude molecular sieve particles. There are four groups of sliding plates 301b, which are respectively arranged on both sides of the two extrusion plates 301a. There are two groups of sliding blocks 301c, push blocks 301d and push plates 301e, which are respectively arranged above the two molecular sieve cylinders 201b.

[0038] By setting the sliding plate 301b, sliding block 301c, pushing block 301d and pushing plate 301e, after the cover plate 201a is engaged with the box body 102, a thrust can be applied to the extrusion plate 301a again to make the molecular sieve particles arranged more densely, thereby improving the oxygen concentration and efficiency.

[0039] After pouring new molecular sieve particles into the molecular sieve cylinder 201b, the cover plate 201a is moved to the top of the box body 102, and the positions of the fixed block 201d and the rotating column 201c are aligned with the position of the through groove 201a-1. Then, pressure is applied to the cover plate 201a until the cover plate 201a is clamped to the box body 102. At this time, the rotating column 201c is rotated, and the rotating column 201c drives the push plate 301e to move. The push plate 301e pushes the push block 301d to move and applies a thrust to the sliding block 301c, thereby moving the sliding plate 301b. The sliding plate 301b applies a downward thrust to the extrusion plate 301a, thereby driving the extrusion plate 301a to squeeze the molecular sieve particles, making the molecular sieves arranged more tightly, thereby increasing the oxygen production concentration.

[0040] Example 2

[0041] Reference Figures 1-9 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0042] Specifically, the extrusion assembly 300 further includes a sliding groove 301f and a sliding shaft 301g. The sliding groove 301f is provided on one side of the sliding plate 301b, and the sliding shaft 301g is fixed on one side of the sliding plate 301b.

[0043] The number of the sliding grooves 301f corresponds to the number of the sliding shafts 301g. Through the cooperation of the sliding grooves 301f and the sliding shafts 301g, the sliding plate 301b can slide in the sliding grooves 301f. Since the sliding plate 301b is fixed to the extrusion plate 301a and the cover plate 201a, when the sliding plate 301b slides in the sliding grooves 301f, the relative position height of the cover plate 201a and the extrusion plate 301a will change.

[0044] Specifically, the extrusion assembly 300 further includes a first spring 301h. One end of the first spring 301h is fixed to one side of the extrusion plate 301a, and the other end of the first spring 301h is fixed to one side of the cover plate 201a.

[0045] The first spring 301h is used to pre-press the molecular sieve particles. When the positions of the fixed block 201d and the rotating column 201c correspond to the position of the through slot 201a-1, the cover plate 201a is moved close to the molecular sieve cylinder 201b. At this time, the extrusion plate 301a will slowly approach the molecular sieve particles. The molecular sieve particles will generate an upward thrust on the extrusion plate 301a, and then apply a thrust to the first spring 301h. At the same time, the first spring 301h will apply a downward thrust to the extrusion plate 301a to squeeze the molecular sieve particles.

[0046] Specifically, the extrusion assembly 300 further includes a rotating block 301i. An annular groove 201c-1 is defined in the rotating column 201c, and the rotating block 301i is fixed to the inner wall of the annular groove 201c-1.

[0047] There are two rotating blocks 301i. When the rotating column 201c rotates, the curved surface of the rotating block 301i will squeeze the push plate 301e, driving the sliding shaft 301g to slide in the slide groove 301f, and then after the cover plate 201a is engaged with the box body 102, the molecular sieve particles are compressed again to ensure the oxygen concentration.

[0048] Specifically, the extrusion assembly 300 further includes a fixed shaft 301j, and the fixed shaft 301j is plugged into the sliding plate 301b.

[0049] By setting the fixed shaft 301j, the sliding plates 301b rotate around the fixed shaft 301j. When one of the sliding plates 301b moves, it will move the other sliding plates 301b, thereby pushing the extrusion plate 301a to extrude the molecular sieve particles.

[0050] When the rotating column 201c is rotated, the annular groove 201c-1 is driven to rotate, and the rotating block 301i rotates along the annular groove 201c-1. The curved surface of the rotating block 301i contacts the end face of the push plate 301e and pushes the push plate 301e to move along the slot 201a-3 in the direction away from the rotating column 201c. At this time, the other end face of the push plate 301e will drive the push block 301d to move along the sliding groove 201a-2. At the same time, since the sliding block 301c is fixed to the sliding shaft 301g, it drives the sliding shaft 301g to slide in the sliding groove 301f in the direction away from the rotating column 201c. The sliding shaft 301g drives the sliding plate 301b to move. Through the cooperation of the fixed shaft 301j and the sliding plate 301b, the extrusion plate 301a moves downward, thereby squeezing the molecular sieve particles and making them arranged more closely, thereby improving the oxygen concentration and oxygen production efficiency of the oxygen generator.

[0051] Specifically, the installation assembly 200 further includes a locking member 202, including a movable column 202a, and the cover plate 201a is provided with a movable groove 201a-4, and the movable column 202a is movably connected to the movable groove 201a-4.

[0052] The locking member 202 is provided to lock the cover 201a with the box body 102, thereby preventing the cover 201a from being separated from the box body 102, which would result in insufficient sealing of the molecular sieve and thus affect the normal operation and performance of the oxygen concentrator.

[0053] There are two groups of moving columns 202a and moving grooves 201a-4. The top of the moving column 202a is arc-shaped, which makes it easier for the fixed block 201d to push the moving column 202a back into the moving groove 201a-4, thereby preventing the moving column 202a from obstructing the rotating moving column 202a.

[0054] Example 3

[0055] Reference Figures 1-9 , which is the third embodiment of the present utility model, and is based on the first two embodiments.

[0056] Specifically, the locking member 202 further includes a second spring 202b, and two ends of the second spring 202b are respectively fixed to the moving column 202a and the moving slot 201a-4.

[0057] The second spring 202b is used to ensure that the relative height of the movable column 202a is higher than the bottom surface of the fixed block 201d in the absence of other external forces, thereby preventing the fixed block 201d from moving and affecting the sealing of the molecular sieve.

[0058] Specifically, the installation assembly 200 further includes a rubber ring 201f, and the rubber ring 201f is fixed to one side of the cover plate 201a.

[0059] The rubber ring 201f is used to seal the molecular sieve.

[0060] Specifically, it also includes a box assembly 100, including a support plate 101 and a box 102. The support plate 101 is arranged on one side of the molecular sieve cartridge 201b, and the box 102 is located outside the molecular sieve cartridge 201b.

[0061] The support plate 101 is used to fix the molecular sieve cartridge 201b to the box body 102 to ensure that the position of the molecular sieve cartridge 201b does not move during the pouring process.

[0062] Specifically, the box assembly 100 further includes an oxygen production mechanism 103 , which is fixed in the box 102 .

[0063] The oxygen production mechanism 103 is used to produce oxygen.

[0064] During use, first rotate the rotating column 201c to drive the fixed block 201d to rotate, so that the positions of the fixed block 201d and the rotating column 201c correspond to the position of the through groove 201a-1, release the fixation of the cover plate 201a and the box body 102, and then separate the cover plate 201a from the box body 102, and turn the box body 102 upside down to pour out the old molecular sieve particles.

[0065] After pouring new molecular sieve particles into the molecular sieve cylinder 201b, move the cover plate 201a to the top of the box body 102, and at the same time, adjust the positions of the fixed block 201d and the rotating column 201c to correspond to the position of the through groove 201a-1, and then apply pressure to the cover plate 201a until the cover plate 201a is clamped to the box body 102. At this time, the extrusion plate 301a will slowly approach the molecular sieve particles, and the molecular sieve particles will generate an upward thrust on the extrusion plate 301a, and then apply a thrust to the first spring 301h. At the same time, the first spring 301h will apply a downward thrust to the extrusion plate 301a to squeeze the molecular sieve particles.

[0066] At this time, the rotating column 201c is rotated, and the rotating column 201c drives the annular groove 201c-1 to rotate. At the same time, the rotating block 301i rotates along the annular groove 201c-1. The curved surface of the rotating block 301i contacts the end face of the push plate 301e, and pushes the push plate 301e to move along the card groove 201a-3 away from the rotating column 201c. At this time, the other end face of the push plate 301e drives the push block 301d to move along the sliding groove 201a-2, and the push block 301d brings The movable sliding block 301c moves. At the same time, since the sliding block 301c is fixed to the sliding shaft 301g, the sliding shaft 301g is driven to slide in the slide groove 301f in the direction away from the rotating column 201c. The sliding shaft 301g drives the sliding plate 301b to move. Through the cooperation of the fixed shaft 301j and the sliding plate 301b, the extrusion plate 301a moves downward, thereby squeezing the molecular sieve particles and making them arranged more closely, thereby improving the oxygen concentration and oxygen production efficiency of the oxygen concentrator.

[0067] When the molecular sieve needs to be replaced again, just repeat the operation.

[0068] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
