Description

Technical Field

[0001] This utility model belongs to the field of oxygen generator technology, specifically relating to a molecular sieve quick-release structure and an oxygen generator with the structure. Background Technology

[0002] A molecular sieve oxygen concentrator is a device that uses the adsorption properties of molecular sieves to separate and produce high-purity oxygen from the air. It primarily relies on the adsorption of molecular sieves to separate oxygen and nitrogen. The lifespan of the molecular sieve particles affects the oxygen concentrator's efficiency. To prevent a decline in oxygen production during use, the molecular sieve needs to be replaced promptly when it reaches its lifespan or when a performance degradation is detected. However, due to the complex internal structure of the molecular sieve cylinder, disassembly is not convenient for non-professionals.

[0003] Chinese patent CN213375841U discloses a quick-release sealed molecular sieve, which simplifies the replacement of the molecular sieve structure through its modular design, allowing for direct insertion and removal. However, the overall gas channel and interface design of this structure are relatively complex, requiring insertion and removal at multiple points during replacement, and each insertion point needs to be aligned during replacement, making the replacement process still quite difficult. Therefore, a complete replacement scheme for the molecular sieve cylinder is proposed, and through structural improvements, a quick-release molecular sieve structure has been designed for application in oxygen generators. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a molecular sieve quick-release structure and an oxygen generator with the structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A quick-release molecular sieve structure includes: a shell with an opening structure on one side; a molecular sieve fixed inside the opening structure of the shell, with an upper sieve cover and a lower sieve cover integrating a pressure equalization valve at the upper and lower ends of the molecular sieve, respectively; a molecular sieve air inlet and a molecular sieve oxygen outlet, respectively located on the upper sieve cover and the pressure equalization valve; an oxygen adapter located on the upper sieve cover; one end of the oxygen adapter has an adapter interface, and the adapter interface is connected to the molecular sieve oxygen outlet through a gas guide channel; the other end of the oxygen adapter has an oxygen supply port; the molecular sieve air inlet and the oxygen supply port are connected to the outside gas path through the opening structure.

[0006] Furthermore, the opening directions of the molecular sieve air inlet and oxygen supply outlet are consistent, and their outer end faces are flush.

[0007] Furthermore, the opening directions of the molecular sieve air inlet and the oxygen supply port are arranged longitudinally.

[0008] Furthermore, the opening directions of the molecular sieve air inlet and the oxygen supply port are horizontal.

[0009] Furthermore, sealing rings are fitted onto the outer sides of the molecular sieve air inlet and the oxygen supply port.

[0010] Furthermore, both the upper screen cover and the lower screen cover are provided with connecting lugs, and the connecting lugs and the outer shell are fixedly connected by bolts.

[0011] Furthermore, the adapter is disposed through the edge of the upper screen cover near the opening structure on the outer shell side.

[0012] Furthermore, it also includes: a connecting block, disposed on the upper sieve cover; the molecular sieve air inlet and the oxygen supply port are both opened on the connecting block, and the connecting block is integrally provided with an extension with an internal hollow structure for communicating with the adapter.

[0013] Furthermore, the connecting block is provided with bolt holes for connecting to the outer casing.

[0014] An oxygen generator includes the molecular sieve quick-release structure described in this application.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: the molecular sieve is modularly designed, and the molecular sieve structure is optimized from the perspective of air passages and interfaces. Compared with molecular sieves with more complex structures, the cost of the molecular sieve in this application is reduced. There is no need to plug and unplug the internal pipes of the molecular sieve, and it can be directly replaced. Moreover, all external interfaces are located on the top, which is convenient for operation and saves users' maintenance costs. By changing the connection direction of the external interface, two quick-release structures for molecular sieves are provided, which can replace the molecular sieve from the horizontal and vertical directions respectively, adapting to different oxygen generators and making it highly practical.

[0027] To facilitate understanding of this utility model, it will be described in more detail below with reference to the accompanying drawings and specific embodiments. However, this utility model can be implemented in many different forms and is not limited to the embodiments described in this specification. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0028] Combination Figure 1 Understanding a quick-release molecular sieve structure includes: a housing 1 with an opening on one side; a molecular sieve 2 fixed within the opening of the housing 1, with an upper sieve cover 201 and a lower sieve cover 202 integrating a pressure equalization valve 203 at its upper and lower ends; a molecular sieve air inlet 204 and a molecular sieve oxygen outlet 205 respectively located on the upper sieve cover 201 and the pressure equalization valve 203; an oxygen adapter 3 located on the upper sieve cover 201; one end of the oxygen adapter 3 has an adapter interface 301 connected to the molecular sieve oxygen outlet 205 via a gas guide channel 303; the other end of the oxygen adapter 3 has an oxygen supply port 302; the molecular sieve air inlet 204 and the oxygen supply port 302 are connected to the outside gas path through the opening structure.

[0029] Working process description: In this embodiment, the molecular sieve 2 has an upper sieve cover 201 and a lower sieve cover 202 with an integrated pressure equalization valve 203 at its upper and lower ends, respectively. Compressed air enters directly from the molecular sieve inlet 204 on the upper sieve cover 201. The oxygen obtained by separation by the molecular sieve 2 flows from the molecular sieve outlet 205 on the pressure equalization valve 203 through the air guide channel 303 to the adapter 301, flows through the oxygen adapter 3, and then flows out from the oxygen supply port 302. In this embodiment, the molecular sieve 2 is modularly designed. When disassembling, only the molecular sieve inlet 204 and the oxygen supply port 302 need to be plugged in and unplugged. When installing, only the molecular sieve inlet 204 and the oxygen supply port 302 need to be connected, reducing the number of plugging and unplugging interfaces. Moreover, the molecular sieve inlet 204 and the oxygen supply port 302 are both located on the upper sieve cover 201, which is a relatively simple position, reducing the difficulty of plugging and unplugging operations, thereby enabling quick disassembly of the molecular sieve 2.

[0030] To facilitate assembly with other components, the molecular sieve inlet 204 and oxygen supply inlet 302 have the same opening direction, and their outer end faces are flush. This structural design also reduces the difficulty of processing.

[0031] Specifically, the opening directions of the molecular sieve air inlet 204 and oxygen supply port 302 are both longitudinally arranged or both are horizontally arranged. The technical solutions in this application are described in detail below with reference to Embodiment 1 and Embodiment 2.

[0032] Example 1: Combination Figure 2 The opening directions of the molecular sieve air inlet 204 and oxygen supply port 302 are both longitudinally oriented. Specifically, the molecular sieve 2 is configured with two barrels, and the upper sieve cover 201 is provided with a first air inlet 207 and a second air inlet 208. Both the first air inlet 207 and the second air inlet 208 are used for compressed air intake, which is the specific design of the molecular sieve air inlet 204 in this embodiment. The opening directions of the first air inlet 207, the second air inlet 208, and the oxygen supply port 302 are all longitudinally upward, and their outer end faces are flush. With this structural design, the disassembly and docking direction of the molecular sieve 2 with the external air passage interface is vertically oriented, and during quick disassembly operations, it is removed vertically.

[0033] The quick-release molecular sieve structure in this embodiment is applied in an oxygen generator, such as... Figure 3As shown in the diagram, the arrow indicates the direction of movement of the molecular sieve quick-release structure during disassembly. This structure is installed on one side of the oxygen generator base 5. During disassembly, first remove the connecting screws between the bottom of the outer shell 1 and the base 5. This allows the outer shell 1 and the molecular sieve 2 inside to slide downwards. Then, remove the connecting screws between the molecular sieve 2 and the outer shell 1, which allows the molecular sieve 2 to be separated from the outer shell 1, making disassembly very convenient. To assist in the insertion and removal of the first air inlet 207, the second air inlet 208, and the oxygen supply port 302 from the external air passage, a detachable side grille can be provided. First, remove the grille to disconnect it from the external air passage connection, and then slide out the molecular sieve quick-release structure.

[0034] Example 2: Combination Figure 4-5 It is understood that the opening directions of the molecular sieve air inlet 204 and oxygen supply port 302 are both horizontal. Specifically, as in Embodiment 1, the molecular sieve 2 is arranged in a double-barrel configuration; in this embodiment, the molecular sieve air inlet 204 is designed as a third air inlet 401 and a fourth air inlet 402, and the interface for outputting oxygen is an oxygen outlet 403. The third air inlet 401, the fourth air inlet 402, and the oxygen outlet 403 are all opened on the connecting block 4 and have the same opening direction, are horizontal, and have their outer end faces flush; the connecting block 4 is provided on the upper sieve cover 201; and the connecting block 4 is integrally provided with an extension 404 with an internal hollow structure, the extension 404 being used for communication between the oxygen outlet 403 and the adapter 301. A connecting block 4 is provided, on which the third air inlet 401, the fourth air inlet 402 and the oxygen outlet 403 are integrated with the same opening orientation and the end faces are flush. When the molecular sieve 2 is disassembled or connected to the external gas path, it can be completed simply by inserting or docking the connecting block 4 in the horizontal direction, which simplifies the operation.

[0035] The quick-release molecular sieve structure in this embodiment is applied in an oxygen generator, such as... Figure 6 As shown in the diagram, the arrow indicates the direction of movement of the quick-release molecular sieve structure during disassembly. This quick-release molecular sieve structure is installed on one side of the oxygen generator base 5. During disassembly, first remove the connecting screws between the bottom and / or side and / or top of the outer shell 1 and the base 5. Then, pull the outer shell 1 and the molecular sieve 2 inside it out laterally. Finally, remove the connecting screws between the molecular sieve 2 and the outer shell 1. This will allow the molecular sieve 2 to be separated from the outer shell 1, which is very convenient.

[0036] In one embodiment, the connecting block 4 is provided with bolt holes 405 for connecting to the outer shell 1. This is a method of fixing the molecular sieve 2 to the outer shell 1.

[0037] In one embodiment, sealing rings are fitted around the outer sides of the molecular sieve air inlet 204 and the oxygen supply port 302. This prevents air leakage at the connection point after the molecular sieve air inlet 204 and the oxygen supply port 302 are connected to the external gas interface. The maximum temperature of the molecular sieve 2 is 30~40℃, and silicone sealing rings can be used. These rings are not easily aged or damaged within this temperature range, thus meeting the requirements for sealing and service life.

[0038] In one embodiment, both the upper sieve cover 201 and the lower sieve cover 202 are provided with connecting lugs 206, and the connecting lugs 206 and the outer shell 1 are fixedly connected by bolts. This is one way of fixing the molecular sieve 2 to the outer shell 1. In use, the molecular sieve 2 needs to be fixed. With this fixing method, the molecular sieve 2 can be separated from the outer shell 1 by loosening the bolts, thus completing the disassembly.

[0039] In one embodiment, the adapter 301 is disposed through the edge of the upper sieve cover 201 near the opening structure on the outer shell 1. Positioning the adapter 301 in this location facilitates communication between the adapter 301 and the oxygen outlet 205 of the molecular sieve via the gas guide channel 303.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
