Description
TECHNICAL FIELD
[0001] The utility model belongs to oxygen generator technical field, and specifically relates to an oxygen generator with molecular sieve module. BACKGROUND
[0002] The molecular sieve type oxygen generator is an equipment for extracting oxygen from air based on the pressure swing adsorption (PSA) technology. The oxygen generator uses the physical adsorption and desorption technology of the molecular sieve to fill the molecular sieve in the molecular sieve tank, and the nitrogen in the air can be adsorbed when pressurized, and the un-adsorbed oxygen is collected and becomes high-purity oxygen after purification. The specific working process is that the external air enters the air compressor after filtration, and then enters the molecular sieve tank through the switching valve. In the molecular sieve tank, the nitrogen is adsorbed by the molecular sieve, and the oxygen is accumulated at the top of the adsorption tower and then enters the oxygen storage tank, and then the finished product gas is filtered through the pressure stabilizing valve and the dust and bacteria removing filter to obtain qualified medical oxygen. Generally, the oxygen generator is provided with two molecular sieve tanks, and the switching valve is used to make them alternately pressurized and exhausted, so that the two molecular sieve tanks work cyclically, thereby realizing the continuous oxygen supply of the oxygen generator.
[0003] The molecular sieve tank is one of the internal core components of the oxygen generator, and currently the user can only replace the entire oxygen generator when the molecular sieve cannot work normally. Therefore, the use of the oxygen generator by the user is limited, and the use cost is high. Especially with the progress of technology and the change of market demand, the oxygen generator tends to be smaller and smaller, but the working life of the molecular sieve of the small oxygen generator is much lower than that of the traditional large oxygen generator. Therefore, the entire molecular sieve tank needs to be replaced when the molecular sieve reaches the working life. Due to the limitation of the structure of the traditional molecular sieve tank, the process flow of replacing the molecular sieve tank is relatively complicated, the machine shell of the oxygen generator needs to be opened, and the pipeline needs to be replaced, so only professional after-sales maintenance personnel can operate.

[0048] As long as possible, the various aspects and features described and illustrated in the specification can be applied individually, and these individual aspects can be the subject of a divisional application.
[0049] Referring to Figures 1-12 It is an embodiment of an oxygen generator with a molecular sieve module provided by the present application, and the oxygen generator with a molecular sieve module 100 comprises a main support 10 and a molecular sieve module 30, the molecular sieve module 30 is detachably mounted on the main support 10, and a locking structure is used to lock the molecular sieve module 30 on the main support 10. The locking structure has a locking groove 35 provided on the molecular sieve module 30, a locking piece 15 and an unlocking button 16 provided on the main support 10, and the locking piece 15 and the unlocking button 16 are movably arranged on the main support 10. The locking piece 15 is locked on the molecular sieve module 30 by moving and cooperating with the locking groove 35, and is unlocked after exiting the locking groove 35. The dismounting direction of the molecular sieve module 30 is perpendicular to the movable direction of the locking piece 15.
[0050] In this embodiment, the locking structure has a locking groove 35 and a movable locking piece 15 that match each other, ensuring that the installation position of the molecular sieve module 30 on the main support 10 is accurate and stable; the dismounting direction of the molecular sieve module 30 is arranged vertically to the movable direction of the locking piece 15, so that the locking piece 15 and the locking groove 35 have high locking stability, reducing the shaking gap of the molecular sieve module 30 after installation; the locking piece 15 can form an effective block in the dismounting direction, further enhancing the firmness of the fixation, so that it can be stably installed on the main support 10. And the dismounting operation of the molecular sieve module 30 is simple, only needs to align the molecular sieve module 30 with the main support 10 and move to the position along the dismounting direction, and then push the locking piece 15 to insert it into the locking groove 35 to complete the locking, the operation is relatively simple and direct, does not need complex dismounting steps or additional tool assistance, which is conducive to improving the dismounting efficiency. And the structure of the locking structure is simple, the movement mode is clear, which ensures the reliability of the locking and unlocking functions of the molecular sieve module 30 during the use of the oxygen generator 100, which is conducive to reducing failures.
[0051] In some other embodiments of the present application, the locking structure can also be a locking groove arranged on the main support 10 and a limiting groove arranged on the molecular sieve module 30.
[0052] In some embodiments of the present application, the locking groove 35 protrudes from the molecular sieve module 30, and the locking groove 35 is preferably arranged to protrude downward from the molecular sieve module 30. The main support 10 is provided with a limiting groove 17 for accommodating the locking groove 35, and the limiting groove 17 is arranged to match the locking groove 35; and the limiting groove 17 is preferably arranged to be concave on the main support 10. A first opening 171 for the locking groove 35 to extend into and a second opening 172 for the locking piece 15 to extend into are arranged on the limiting groove 17. When the installation operation of the molecular sieve module 30 on the main support 10 is performed, the protruding locking groove 35 and the matching limiting groove 17 cooperate with each other to provide accurate installation position guidance for the molecular sieve module 30. The locking groove 35 is located in the limiting groove 17, and this nested structure forms an effective constraint on the molecular sieve module 30 in the horizontal direction, which is conducive to increasing the stability of the molecular sieve module 30 after fixation. When the molecular sieve module 30 needs to be maintained or replaced, the arrangement of the locking groove 35 and the limiting groove 17 makes the dismounting process relatively more standardized and convenient; the operator only needs to press the unlocking button 16 to push the locking piece 15 out of the locking groove 35, and then the molecular sieve module 30 can be smoothly removed from the main support 10.
[0053] In some embodiments of the present application, a positioning structure is arranged between the limiting groove 17 and the locking groove 35, which has a positioning block 173 arranged on the limiting groove 17 and a positioning opening 351 arranged on the limiting groove 35 and matched with the positioning block 173. When installing the molecular sieve module 30, although the cooperation of the locking groove 35 and the limiting groove 17 can provide a certain degree of installation position guidance, the arrangement of the positioning block 173 and the positioning opening 351 further refines the positioning in a more microscopic level, thereby ensuring that the gas pipeline, power connector and other components on the molecular sieve module 30 accurately connect with the corresponding components on the main support 10, and guarantees the high accuracy of internal connection and cooperation of the oxygen generator 100. When the molecular sieve module 30 is installed in place, the positioning block 173 is embedded in the positioning opening 351, which not only plays an accurate role in positioning, but also increases the reliability of the connection between the locking groove 35 and the limiting groove 17 to a certain extent.
[0054] In some other embodiments of the present application, a positioning opening can be arranged on the limiting groove 17, and a positioning block is arranged on the limiting groove 35.
[0055] In some embodiments of the present application, the positioning block 173 has a first positioning rib 1731 and a second positioning rib 1732 arranged intersectingly; preferably, the first positioning rib 1731 and the second positioning rib 1732 are arranged vertically. The positioning opening 351 has a first positioning hole 3511 matched with the first positioning rib 1731 and a second positioning hole 3512 matched with the second positioning rib 1732; the height of the first positioning rib 1731 is greater than the height of the second positioning rib 1732. The first positioning rib 1731 and the second positioning rib 1732 are arranged intersectingly and matched with the corresponding first positioning hole 5311 and the second positioning hole 3512 respectively, which realizes the positioning of the locking groove 35 in two different dimensions and accurately locks the installation position of the molecular sieve module 30 from multiple angles, so that the molecular sieve module 30 is placed more accurately on the main support 10. Since the height of the first positioning rib 1731 is greater than the height of the second positioning rib 1732, during the installation process, the locking groove 35 first enters the limiting groove 17 to preliminarily position the molecular sieve module 30; then the first positioning rib 1731 is inserted into the first positioning hole 3511 for further fine positioning in the direction of the first positioning rib 1731; and when the second positioning rib 1732 is subsequently inserted into the second positioning hole 3512, the position of the molecular sieve module 30 is adjusted more finely in the direction of the second positioning rib 1732. This step-by-step positioning adjustment method can further control the installation position error within a smaller range, and realize a more accurate installation effect than a single-height positioning structure. Moreover, the height difference between the first positioning rib 1731 and the second positioning rib 1732 brings a layered fixing effect, so that the connection between the molecular sieve module 30 and the main support 10 is more stable, and the reliability of the connection is improved.
[0056] In some embodiments of the present application, the locking structure further has a resilient member for pushing the locking piece 15 to move into the locking groove 35; the resilient member can continuously apply pressure to the locking piece 15, and a support column 152 for mounting the resilient member is arranged on the locking piece 15, and the resilient member is sleeved on the support column 152. Pushing the locking piece 15 to move into the locking groove 35 ensures that the locking piece 15 can always remain in the locking groove 35 during normal use of the oxygen generator 100, even if the device is subjected to external disturbances such as vibration, shaking, etc., so that the molecular sieve module 30 is stably fixed on the main support 10. And when the molecular sieve module 30 is installed, after the locking groove 35 and the limiting groove 17 are installed and matched, the position of the locking piece 15 corresponding to the second opening 172, the resilient member will automatically push the locking piece 15 to pass through the second opening 172 and enter the locking groove 35, completing the locking action. The moving direction of the unlocking button 16 when unlocking is perpendicular to the movable direction of the locking piece 15, so that the unlocking operation has a unique operation logic, greatly reducing the probability of misoperation. This perpendicular arrangement is more reasonable in terms of space layout, and can more effectively utilize the limited space inside the oxygen generator 100; the unlocking button 16 and the locking piece 15 can be arranged in different directions respectively, avoiding the space conflict that may be caused by the same or similar moving directions of the two, so that the layout of the components inside the oxygen generator is more compact and orderly. In the present embodiment, the loading and unloading direction of the molecular sieve module 30 is the up-down direction, the unlocking button 16 moves up and down, and the locking piece 15 moves in the front-back direction.
[0057] In some embodiments of the present application, the unlocking button 16 has an inclined force applying surface 1611, and the locking piece 15 has a receiving surface 1501 abutting on the force applying surface 1611 and matching the force applying surface 1611; the force applying surface 1611 is arranged in an inclined manner towards the locking groove 35 in the moving direction of the unlocking button 16 when unlocking; the force applied by the operator can be more smoothly converted into the force for pushing the locking piece 15 out of the locking groove 35 along the inclined surface, making the unlocking operation more labor-saving. In the normal locking state, the close abutting and matching of the receiving surface 1501 and the force applying surface 1611, and the mutual abutting and friction of the inclined surfaces, can enhance the contact stability between the locking piece 15 and the unlocking button 16.
[0058] In some embodiments of the present application, the locking member 15 has a locking body 150, a locking protrusion 151 extending along the locking body 150 towards the locking slot 35, an accommodating surface 1501 on the locking body 150 for cooperating with the unlocking button 16 to achieve unlocking, and a first limiting surface 1502 for limiting the continued movement of the unlocking button 16 after unlocking. The accommodating surface 1501 and the first limiting surface 1502 are arranged close to each other in the movement direction of the unlocking button 16 when unlocking. The first limiting surface 1502 arranged on the locking body 150 can effectively limit the range of continued movement of the unlocking button 16 after unlocking. When the unlocking operation is performed, the unlocking button 16 pushes the locking member 15, and once the unlocking button 16 moves to the position where it contacts the first limiting surface 1502, it cannot continue to move in that direction, thereby accurately controlling the unlocking stroke. The movement limitation of the first limiting surface 1502 on the unlocking button 16 not only controls the unlocking stroke, but also prevents the unlocking button 16 and the locking member 15 and other components connected thereto from over-displacement during the unlocking process.
[0059] In some embodiments of the present application, the unlocking button 16 has an unlocking body 160, and an unlocking protrusion 161 arranged on one end of the unlocking body 160 close to the locking member 15. The accommodating surface 1501 and the first limiting surface 1502 on the locking body 150 form an unlocking cavity 1503, and the unlocking protrusion 161 is movably located in the unlocking cavity 1503. The unlocking protrusion 161 has a force applying surface 1611 matching the accommodating surface 1501 and a second limiting surface 1612 matching the first limiting surface 1502. During the unlocking operation, when the unlocking protrusion 161 moves with the pushing of the unlocking button 16, once the second limiting surface 1612 contacts the first limiting surface 1502, the movement stroke of the unlocking button 16 is accurately limited, ensuring that the unlocking action is just completed to the appropriate extent, neither incomplete unlocking resulting in the molecular sieve module 30 failing to be smoothly disassembled, nor over-unlocking causing the locking member 15 to move too much, thereby causing subsequent installation inconvenience or collision with other components, etc.
[0060] Advantages of the specific structure of the unlocking button 16 and the locking member 15:
[0061] First, accurate stroke control: the unlocking protrusion 161 is movably located in the unlocking cavity 1503 formed by the accommodating surface 1501 and the first limiting surface 1502 on the locking body 150, and the unlocking protrusion 161 has the second limiting surface 1612 matching the first limiting surface 1502. For example, when the molecular sieve module 30 needs to be disassembled for actual maintenance of the oxygen generator 100, this accurate stroke control can ensure that the locking member 15 is accurately and accurately unlocked from the locking slot 35 each time, so that the disassembly process can be smoothly carried out according to the standard process.
[0062] Second, clear operation feedback: the force surface 1611 on the unlocking convex 161 matches the receiving surface 1501 of the locking body 150. When the unlocking button 16 is pushed to perform the unlocking operation, the operator can clearly feel the force transmission through the contact between the finger and the force surface 1611 of the unlocking convex 161. With the movement of the unlocking button 16, the force surface 1611 gradually separates from the receiving surface 1501. When the force surface 1611 completely separates from the receiving surface 1501 and the second limiting surface 1612 contacts the first limiting surface 1502, the operator can clearly perceive this change process, thereby obtaining clear feedback about whether the unlocking operation is completed, facilitating accurate judgment of the operation process. This helps to ensure that the entire locking structure continues to function effectively, thereby ensuring the stability of the molecular sieve module 30 on the main support 10, preventing problems such as module loosening or accidental unlocking due to abnormal component cooperation.
[0063] In some embodiments of the present application, a mounting hole 19 for mounting the unlocking button 16 is provided on the main support 10, and a mounting cylinder 191 extending along the edge of the mounting hole 19 towards the locking piece 15 is provided. The unlocking button 16 protrudes and abuts against the locking piece 15. The mounting hole 19 provides an accurate mounting position for the unlocking button 16, allowing it to be accurately installed at a predetermined position on the main support 10. The mounting cylinder 191 further positions and fixes the unlocking button 16, limiting the displacement of the unlocking button 16 in directions other than the preset movement direction, ensuring that it is stably and accurately installed on the main support 10. The mounting cylinder 191 also increases the contact area between the main support 10 and the unlocking button 16. The unlocking button 16 protrudes from the mounting cylinder 191 and abuts against the locking piece 15, ensuring that the force applied by the operator on the unlocking button 16 can be effectively transmitted to the locking piece 15 during the unlocking operation.
[0064] In some embodiments of the present application, the unlocking button 16 has a movable unlocking body 160 located in the mounting cylinder 191, and a limiting edge 162 extending along the unlocking body 160 and abutting against one end of the mounting cylinder 191 close to the locking piece 15. The limiting edge 162 abuts against one end of the mounting cylinder 191 close to the locking piece 15, providing good limiting effect on the unlocking button 16 in the vertical direction.
[0065] In some embodiments of the present application, the oxygen generator 100 comprises a main support 10, and a molecular sieve module 30 detachably mounted on the main support 10. Specifically, the main support 10 has a base portion 11 and a vertical portion 12 arranged on the base portion 11. A first area for mounting the compressor module 20 is formed between one side of the vertical portion 12 and the base portion 11, and a second area for mounting the molecular sieve module 30 is formed between the other side of the vertical portion 12 and the base portion 11. The molecular sieve module 30 is mounted on the second area from top to bottom. A slide rail structure is arranged between the molecular sieve module 30 and the vertical portion 12, and a locking structure is arranged between the molecular sieve module 30 and the base portion 11. An installation hole 19 is arranged on the lower end surface of the base portion 11. The unlocking button 16 is pushed to move upward, and the locking between the locking piece 15 and the locking groove 35 is released.
[0066] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit the present application.
