[0051] 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.
[0052] Referring to Figures 1-8 It is an embodiment of the molecular sieve module provided by the present application, a molecular sieve module 30 comprises: a shell 31, a molecular sieve device 32 and an exhaust silencer 33, the shell 31 is surrounded to form a containing cavity, the molecular sieve device 32 and the exhaust silencer 33 are located in the containing cavity, and the exhaust silencer 33 is used for silencing nitrogen gas discharged from the molecular sieve device 32. The exhaust silencer 33 has an exhaust port 331 located between the molecular sieve device 32 and the shell wall of the shell 31, and the tank wall of the molecular sieve device 32 and the shell wall surround to form an exhaust space 311, and the exhaust space 311 is used for the exhaust port 331 to exhaust.
[0053] In the embodiment, when the ambient temperature of the oxygen generator 100 is low, such as in winter, the temperature of the nitrogen gas discharged from the exhaust silencer 33 will be higher than the ambient temperature; the nitrogen gas discharged from the molecular sieve device 32 is discharged into the exhaust space 311 after silencing, so that the nitrogen gas in the exhaust space 311 can heat and insulate the tank wall of the molecular sieve device 32, so that the molecular sieve module 30 can work efficiently in a low-temperature environment. The molecular sieve module 30 is provided with the shell 31 wrapped on the outside, and the molecular sieve module 30 can be replaced as an independent component, which greatly reduces the use cost of the user and improves the maintainability of the oxygen generator; and the molecular sieve module 30 is replaced as a whole, which is beneficial to ensure the operation efficiency of the replacement. The exhaust silencer 33 is provided, which is specially used for silencing the nitrogen gas discharged from the molecular sieve device 32, which can effectively reduce the noise generated by the nitrogen gas during the operation of the oxygen generator 100, improve the use comfort of the oxygen generator 100, and reduce the interference of the noise on the user and the surrounding environment.
[0054] In some embodiments of the present application, the exhaust silencer 33 has a silencing cavity 330 located at one end of the exhaust space 311, and an exhaust port 331 is formed at the end of the silencing cavity 330 to exhaust to the other end of the exhaust space 311, or the silencing cavity 330 is located at one side of the exhaust space 311, and the exhaust port 331 exhausts to the other side of the exhaust space 311. The one end of the exhaust space 311 is opposite to the other end. The exhaust silencer 33 is normally vertically arranged, for example, the silencing cavity 330 can be arranged at the lower part of the exhaust space 311, and the exhaust port 331 is located at the top of the silencing cavity 330, and exhausts upward; or the silencing cavity 330 can be arranged at the upper part of the exhaust space 311, and the exhaust port 331 is located at the bottom of the silencing cavity 330, and exhausts downward. The exhaust port 331 can also be arranged to exhaust horizontally, for example, the silencing cavity 330 is arranged at the front side of the exhaust space 311, and the exhaust port 331 exhausts rearward; or the silencing cavity 330 is arranged at the front side of the exhaust space 311, and the exhaust port 331 exhausts forward. The silencing cavity 330 can be arranged at the left side of the exhaust space 311, and the exhaust port 331 exhausts rightward; or the silencing cavity 330 is arranged at the right side of the exhaust space 311, and the exhaust port 331 exhausts leftward.
[0055] The exhaust silencer 33 is partially or entirely located in the exhaust space 311, and after the nitrogen gas is exhausted from the exhaust port 331, it flows along the extension direction of the tank wall of the molecular sieve device 32 and the shell wall of the shell in the exhaust space 311, so that the nitrogen gas can flow through the tank wall with an increased area on the exhaust path, thereby achieving a better heating and insulation effect on the molecular sieve device 32.
[0056] In some embodiments of the present application, an exhaust gap for accommodating the gas in the exhaust space 311 is arranged on the shell 31 near one end of the exhaust silencer 33, so that there are an exhaust area in the exhaust space 311 in the exhaust direction of the exhaust port 33, and a gas backflow area on both sides of the exhaust silencer 33. The length of the molecular sieve device 32 is less than the length of the exhaust space 311. The exhaust gap is arranged near one end of the exhaust silencer 33, and the exhaust port 331 is arranged to exhaust away from the exhaust gap, so that after the nitrogen gas is exhausted into the exhaust space 311, it first flows away from the exhaust gap in the exhaust area, and then at least part of the nitrogen gas flows in the direction close to the exhaust gap in the gas backflow area, thereby realizing the detour flow of the nitrogen gas in the exhaust space 311, which is beneficial to prolong the flow path length of the nitrogen gas in the exhaust space 311 and increase the tank wall area through which the nitrogen gas flows.
[0057] In the embodiment, the sound attenuation cavity 330 is vertically arranged, and the sound attenuation cavity 330 is located at the lower part of the exhaust space 311, and the exhaust port 331 is located at the top of the sound cavity 330. The vertically arranged sound attenuation cavity 330 has a certain length in the vertical direction of the inner wall, which is beneficial to improve the sound attenuation effect. Hot gas is relatively light and flows upward, and this natural convection trend is consistent with the exhaust direction, which helps to push the gas to be discharged from the exhaust port 331 more quickly and smoothly. Preferably, the sound attenuation cavity 330 has an expansion section with a gradually increasing cross-sectional area in the direction close to the exhaust port 331, which is beneficial to the pressure reduction of nitrogen and forms a large-area exhaust end, and the exhaust end is provided with a plurality of exhaust ports 331.
[0058] In the embodiment, the shell 31 has an outer shell 315, a shell bottom 3161 matched with the outer shell 315, and an exhaust gap between the shell bottom 3161 and the outer shell 315 for accommodating the gas in the cavity to be discharged. When the nitrogen flows upward, heat exchange is performed, so that the temperature of the gas is reduced, and then turns to flow back downward; the nitrogen realizes the meandering flow in the exhaust space 311, which is beneficial to prolong the flow path length of the nitrogen in the exhaust space 311. Compared with some methods that may need to design a complex exhaust pipe or opening in other parts of the shell 31 to realize gas discharge, the gap between the shell bottom 3161 and the outer shell 315 is used as an exhaust passage, which simplifies the structure design of the shell 31 to a certain extent; the manufacturing process of the shell 31 can be relatively simple, the production cost is reduced, and the failure points caused by too many complex structures are also reduced, and the reliability of the oxygen generator is improved. The exhaust gap is arranged between the shell bottom 3161 and the outer shell 315, so that the gas has an outlet around the bottom of the shell 31 when being discharged, and uniform exhaust distribution is realized; it is beneficial to reduce the adverse effects such as airflow impact and loud noise caused by too concentrated local exhaust, and further improves the operation stability and use comfort of the oxygen generator.
[0059] In some embodiments of the present application, the molecular sieve device 32 is a square structure, that is, the molecular sieve device 32 has four tank walls arranged in front, back, left and right, and the molecular sieve device 32 has a plurality of tank cavities, an upper cover and a lower cover arranged on the tank cavities; the shell 31 is also a square structure. An exhaust space 311 is formed between the first tank wall 321 of the molecular sieve device 32 and the first shell wall 3151 of the shell 31. The distance between the other tank walls of the molecular sieve device 32 and the adjacent shell walls of the shell 32 is smaller than the distance between the first tank wall 321 and the first shell wall 3151. In order to be compact in structure and reduce the volume as much as possible, the distance between the tank walls of the molecular sieve device 32 and the shell 32 is as small as possible; since the molecular sieve device 32 is partially or entirely arranged in the exhaust space 311, the width of the exhaust silencer 33 matches the width of the exhaust space 311, so the distance between the first tank wall 321 and the first shell wall 3151 needs to be relatively large. The length of the molecular sieve device 32 is smaller than the length of the first tank wall 321, and after the nitrogen gas is discharged upward from the exhaust port 331 to the exhaust space 311, it flows upward in the exhaust area; then most of the gas flows to the return area on both sides and turns downward. Part of the gas will flow to the other tank walls of the molecular sieve device 32 or the return area and flow downward.
[0060] In some other embodiments of the present application, the molecular sieve device 32 can also be arranged in a circular or elliptical shape or other structures, and the exhaust silencer 33 is arranged outside the molecular sieve device 32.
[0061] In some embodiments of the present application, the nitrogen gas is discharged from the molecular sieve device 32 to the exhaust silencer 33, so the exhaust silencer 33 is fixedly arranged on the molecular sieve device 32; so that the cooperation between the two is stronger, and problems such as gas leakage and change of sound propagation path caused by loose connection or gaps are avoided.
[0062] In some embodiments of the present application, two limiting plates 31511 extending inwardly are arranged on the first shell wall 3151 of the shell 31, and the exhaust silencer 33 is located between the two limiting plates 31511. The limiting plates 31511 can effectively limit the horizontal displacement of the exhaust silencer 33 in the exhaust space 311. When the oxygen generator 100 is subjected to external forces such as vibration and shaking during operation, the exhaust silencer 33 is tightly clamped by the two limiting plates 31511 and cannot easily move in the horizontal direction, thereby ensuring the stability of the exhaust silencer 33.
[0063] In some embodiments of the present application, when the outside temperature is low, nitrogen is discharged into the exhaust space 311 to heat and insulate the molecular sieve device 32; when the outside temperature is high, there is no need to heat and insulate the molecular sieve device 32; therefore, an air outlet (not shown in the figure) is provided on the shell wall surrounding the exhaust space 311 and is in communication with the outside, and the air outlet is preferably provided to be openable and closable. The openable and closable air outlet allows flexible control of the exhaust process according to the actual operation of the oxygen generator. Different use environments and working conditions may have different requirements for the exhaust of the oxygen generator. For example, in high-altitude areas, the air is thin, the working number of the oxygen generator may need to be adjusted, and the exhaust condition may also need to be changed accordingly; or the ambient temperature changes. Through the openable and closable air outlet, the exhaust strategy can be easily adjusted according to these different working conditions to ensure that the oxygen generator can operate efficiently and stably under various conditions. When the outside temperature is low, the air outlet is controlled to be closed, so that the flow path of nitrogen in the exhaust space 311 is longer. When the outside temperature is high, the air outlet is controlled to be open, so that the nitrogen discharged upward into the exhaust space 311 can flow out of the molecular sieve module 30 through the air outlet.
[0064] Preferably, the molecular sieve module 30 further comprises a fan for discharging the gas in the exhaust space 311 from the air outlet. The provision of the fan allows the gas in the exhaust space to be discharged from the air outlet under the drive of the fan, achieving active exhaust, accelerating the discharge speed of the gas, and improving the exhaust efficiency. Moreover, the speed of the fan can usually be adjusted according to the operation requirements of the oxygen generator, and by adjusting the speed of the fan, the amount of gas discharged from the exhaust space can be accurately controlled; various specific requirements can be met, so that the operation of the oxygen generator is more in line with the actual application scenario, improving the applicability and flexibility of the oxygen generator.
[0065] In some embodiments of the present application, the shell 31 has a detachable outer shell 315, an inner shell 316 assembled with the outer shell 315, the outer shell 315 and the inner shell 316 surrounding a containing cavity, the outer shell 315 having a U-shaped side wall and a shell top 3152, the inner shell 316 having a shell bottom 3161 and a second side wall 3162 matching the U-shaped side wall, the inner shell 316 being L-shaped, and the shell bottom 3161 and the second side wall 3162 being arranged vertically. When the molecular sieve module 30 is assembled, the molecular sieve device 32 is first fixed on the molecular sieve module 30, then the molecular sieve device 32 is fixed on the inner shell 316, and finally the outer shell 315 is fixed with the inner shell 316. When the molecular sieve module 30 needs to be maintained and inspected, only the outer shell 315 can be disassembled, the screws for fixing the outer shell 315 and the inner shell 316 are disassembled, and then the outer shell 315 can be disassembled; which is conducive to the convenience of maintenance.
[0066] 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. An opening 3163 is formed on the shell wall of the housing 31 near the vertical portion 12, and the partial heat dissipation airflow of the compressor module 20 can enter the housing 31. The entering heat dissipation airflow can reach the outside of the tank wall of the molecular sieve module 30, and can play a role of heating and insulation when the ambient temperature is low.
[0067] Preferably, the exhaust space 311 is located on the side of the containing cavity away from the vertical portion 12, the second side wall 3162 is located on the side close to the vertical portion 12, and the opening 3163 is formed on the second side wall 3162. The second side wall 3162 is arranged opposite to the first shell wall 31511, that is, the heat dissipation gas can reach the left side of the molecular sieve device 32 through the opening 3163, and the exhaust port 331 is located on the right side of the molecular sieve device 32.
