Abstract
Description
Technical Field
[0001] This invention relates to the field of connector technology, specifically to a connector assembly, a compressor, and an oxygen generator. Background Technology
[0002] In the oxygen generator module, the compressor is a key component, and its main function is to continuously supply compressed gas into the molecular sieve chamber. The oxygen generation process relies on the physical adsorption and desorption technology of the molecular sieve to purify oxygen in the air through physical means, ultimately outputting pure oxygen with an oxygen concentration of over 90%. Due to the special properties of the molecular sieve, it has specific requirements for the gas input by the compressor.
[0003] In the home oxygen concentrator industry, low temperature and low pressure have become key research directions to improve the adsorption efficiency of nitrogen by molecular sieves. Among these, effectively reducing the temperature of the gas entering the molecular sieve has become a challenging problem for many R&D engineers. Existing cooling measures have the following drawbacks in practical applications: 1. From the perspective of the compressor as a heat source, although reducing the compressor speed can achieve a certain degree of cooling, it will lead to a decrease in flow rate; 2. From the perspective of gas delivery channels, adding heat sinks or increasing the speed of axial fans will not only cause space shortages, but also increase costs and even increase noise.
[0004] Furthermore, current oxygen concentrators may experience malfunctions in solenoid valves or piping, leading to gas buildup in the pipes and a rapid increase in internal pressure, posing a serious threat to the safety of both the oxygen concentrator and the user. To address this issue, engineers typically connect an external safety relief valve to the compressor's exhaust pipe to release excess high-pressure gas in case of a pipe malfunction, ensuring the safety of both the oxygen concentrator and the user. However, this external relief valve not only increases material and installation costs but also presents a greater challenge to the already limited space within the oxygen concentrator.
[0005] Therefore, how to overcome the shortcomings of the existing technology is the subject of this invention. Summary of the Invention
[0006] The purpose of this invention is to provide a connector assembly, a compressor, and an oxygen generator.
[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A connector assembly includes a connector body, a heat dissipation component, and a sealing component; The connector body has a venting inner hole and at least one pressure relief channel communicating with the venting inner hole and the outside of the connector body; The sealing components are all movably installed in the pressure relief channels; The heat dissipation component is sleeved on the outside of the connector body, and the contact surface between the two serves as a continuous heat conduction interface. The connector assembly has both a venting state and a depressurization state: In the venting state, the sealing element prevents gas entering the vent hole from being discharged to the outside of the connector body through the pressure relief channel; Under depressurization conditions, some of the gas that enters the vent hole is discharged to the outside of the connector body through the depressurization channel.
[0008] For ease of explanation and understanding, this application describes the connector assembly as being placed vertically during operation, although it can be adjusted in actual use. The application also describes the connector assembly being used in conjunction with a compressor.
[0009] In the above scheme, when the connector assembly is in use, the connector body is connected to the compressor exhaust port to export high-pressure gas to the relevant gas circuit. Specifically, the normal exhaust work is completed by the venting inner hole. At this time, the connector assembly is in the venting state, and the sealing part blocks the pressure relief channel, so that the high-pressure gas can only be discharged through the venting inner hole (ignoring the very small amount of high-pressure gas that may leak out).
[0010] When the pressure inside the vent exceeds the rated value, the force on the sealing component gradually increases due to the high temperature and high pressure. When it exceeds the safety threshold of the compressor, the sealing component will move to release the seal on the pressure relief channel, allowing the pressure relief channel to open and release air. When this application is used in an oxygen generator, the timely pressure relief operation can safely protect the valves, pipelines and other structures.
[0011] During normal venting and depressurization operations of the connector assembly, the heat transferred from the high-pressure gas to the connector body can be quickly dissipated through the heat sink, preventing the connector assembly's service life from being affected by high temperatures.
[0012] With the above configuration, on the one hand, the connector assembly has the function of discharging high-pressure gas into the relevant gas circuit; on the other hand, the connector assembly has the function of timely depressurization to avoid damage to compressors and other related equipment; furthermore, the connector assembly has the characteristic of quickly dissipating heat to extend its own service life.
[0013] It should be emphasized that, taking the application of this application to a compressor and the compressor to an oxygen concentrator as an example, this application only improves the existing exhaust connector. While retaining the function of the exhaust connector to discharge high-pressure gas from the compressor, it achieves the two important effects of reducing the compressor outlet temperature and safe pressure relief. Moreover, it does not require increasing the internal space of the oxygen concentrator or changing the layout of the internal components of the oxygen concentrator, and has strong practicality and reliability.
[0014] In a further technical solution, the connector body includes a connecting section and a pressure relief section connected together, and the pressure relief channel is disposed in the pressure relief section; Along the direction from the connecting section toward the pressure relief section, the size of the pressure relief section gradually decreases; The heat sink has a locking cavity for engaging with the pressure relief section, and the locking contact surface of the two serves as the continuous heat conduction interface. Along the direction from the connecting section toward the pressure relief section, the size of the engagement cavity gradually decreases.
[0015] With the size settings in this embodiment, during the installation of the heat sink, the pressure relief section gradually restricts the downward movement of the heat sink, so that the heat sink is fixed while having movable characteristics, which facilitates the operation of moving the heat sink.
[0016] It should be noted that the connection between the connecting section and the pressure relief section is used as an example for explanation. The connection between other structures can be explained in the same way: the connection between the connecting section and the pressure relief section can be an integrated, non-removable connection or a threaded connection that can be separated. This application does not limit these specific connection methods and can adjust them according to the actual situation.
[0017] In a further technical solution, the pressure relief channel is configured as at least two; Each of the pressure relief channels is evenly distributed in a circle around the axis of the connector body.
[0018] When there is only one pressure relief channel, if it becomes blocked, it may fail to relieve pressure or the pressure relief effect may be less than expected, affecting the timeliness and effectiveness of pressure relief. However, by increasing the number of pressure relief channels, this situation can be avoided. In addition, the pressure relief efficiency can be increased to a certain extent.
[0019] In a further technical solution, the pressure relief channel is configured as two.
[0020] The prerequisite for pressure relief is that the sealing component releases the blockage of the pressure relief channel. This requires the pressure inside the connector assembly to reach a certain level. If there are too many pressure relief channels, the pressure inside the pressure relief channels will decrease if the amount of gas entering the vent hole remains the same, causing the sealing component to be unable to move as expected and affecting the timeliness of pressure relief. By limiting the pressure relief channels to two, the risk of being unable to relieve pressure can be reduced, and the impact on the timeliness of pressure relief can also be reduced.
[0021] In a further technical solution, the pressure relief channel includes a first section, a second section, and a third section connected in sequence, wherein the first section is connected to the vent hole, and the third section is connected to the outer side of the connector body; During depressurization, the high-pressure gas enters the second section through the first section and is released to the outside of the connector body through the third section, forming a gas flow path; In the depressurized state, the sealing element is located in a clearance portion in the second section, which is located outside the gas flow path; In the non-depressurized state, the sealing element is located in the second section and blocks the gas flow path.
[0022] This section defines the structural composition of the pressure relief channel. When setting up the pressure relief channel, it can be designed and set up in sections to meet diverse needs.
[0023] The sealing element can be installed in the first, second, or third section depending on the actual situation. This application describes the sealing element as being installed in the second section.
[0024] In a further technical solution, the length direction of the second segment is parallel to the length direction of the connector body; And / or, the length direction of the first segment is perpendicular to the length direction of the connector body; And / or, the length direction of the third segment is perpendicular to the length direction of the connector body; And / or, the sealing element is disposed within the second segment.
[0025] Taking the example of the second segment being parallel to the length direction of the connector body, the effects of other similar examples are explained: Compared to the case where there is an angle between the length direction of the second segment and the length direction of the connector body, the vertical arrangement adopted in this embodiment can reduce the space occupied by the second segment in the radial direction of the connector body, thereby reducing the space occupied by this application in the radial direction of the connector body. Taking the application as an example when used in a compressor, it can adapt to the compact space layout inside the compressor.
[0026] The length of the second section is parallel to the length of the main body of the connector. In addition to the above effects, it also facilitates the vertical movement of the sealing component, especially its downward repositioning, so as to seal the pressure relief channel in a timely manner.
[0027] In a further technical solution, the sealing element is disposed within the second segment; The cross-sectional dimensions of the first segment and the third segment are both larger than the cross-sectional dimensions of the sealing element, so as to restrict the sealing element from entering the first segment and the third segment.
[0028] The first section is the gas inlet section, the third section is the gas outlet section, the second section is the gas delivery section, and the sealing element is located in the second section. During certain time periods, the sealing element needs to perform the operation of restricting gas from entering the third section.
[0029] To facilitate understanding, the movement path of the sealing component is illustrated below: Vertically, positions one, two, and three are set from bottom to top. When the connector assembly is not working, the sealing component is in position one. When the connector assembly is working normally, the sealing component moves upward to position two. When a problem occurs in the connector assembly causing an increase in internal pressure, the sealing component continues to move upward to position three. In position two, the sealing component obstructs gas from entering the third section; for example, the sealing component can directly block the opening connecting the third section to the second section. When the sealing component continues to move upward to position three, it cannot completely block the opening connecting the third section to the second section; for example, the sealing component can be completely above the opening connecting the third section to the second section.
[0030] The size restrictions in this section prevent the sealing element from entering the first and third sections, thereby ensuring the sealing element's long-term operation and the reliability of this application.
[0031] To facilitate understanding of the cross-sectional dimension settings in this section, an example is provided below. Other dimension settings in this application can be understood by referring to this description: Here, the first segment is set to be cylindrical with a longitudinal section radius of A, and the sealing component is set to be a sphere with a radius of B, where B equals A.
[0032] In a further technical solution, the sealing element is disposed within the second segment; The opening portion of the second segment near the end of the first segment is not connected to the first segment, thereby restricting the sealing element from entering the first segment.
[0033] It should be noted that when the connector assembly is used vertically, the sealing element is more likely to enter the first section but less likely to enter the third section.
[0034] This section provides a second method for restricting the sealing element from entering the first section. Here, the cross-sectional dimensions of the first section, the second section, and the sealing element are all the same. When the opening of the second section near the end of the first section is not connected to the first section, the cross-sectional dimension of the area in the opening of the second section near the end of the first section that allows the sealing element to pass through is smaller than the cross-sectional dimension of the sealing element, thereby restricting the sealing element from entering the first section, thus ensuring the continuous operation of the sealing element and ensuring the reliability of this application.
[0035] In a further technical solution, the pressure relief channel includes at least one arc-shaped channel; At least one portion of the inner wall of the arcuate channel is provided to protrude to restrict the sealing element from entering the venting orifice.
[0036] This section provides an alternative design for the pressure relief channel. The arc-shaped channel reduces obstruction to the gas and improves the efficiency of gas discharge through the pressure relief channel.
[0037] This description assumes that the pressure relief channel consists of only one arc-shaped channel. The inner wall of this arc-shaped channel is partially protruding, which restricts the sealing element from entering the vent hole, thereby ensuring the continuous operation of the sealing element and guaranteeing the reliability of this application.
[0038] In a further technical solution, the sealing component is configured as a spherical structure.
[0039] The spherical structure reduces the friction between the sealing element and the inner wall of the pressure relief channel, allowing the sealing element to move in a timely manner and improving the timeliness of pressure relief.
[0040] A further technical solution is that, under ventilated conditions, the heat sink blocks the opening of the pressure relief channel near the outer side of the connector body; Under depressurization conditions, the heat sink gradually separates from the opening of the depressurization channel near the outer side of the connector body.
[0041] The opening of the pressure relief channel near the outside of the connector body refers to the end opening of the third section away from the second section.
[0042] Under pressure relief conditions, the heat sink and the pressure relief channel gradually separate from the opening on the outside of the connector body. They may eventually separate completely or not completely.
[0043] There is usually a gap between the sealing component and the inner wall of the pressure relief channel. Gas can escape through this gap, causing gas leakage. If a sealing structure such as a sealing ring is installed on the sealing component, it will affect the movement of the sealing component during the pressure relief process.
[0044] By using heat dissipation components to seal the opening near the outside of the pressure relief channel, the amount of gas leaking out during non-pressure relief periods can be reduced.
[0045] It should be noted that although the arrangement of the heat sink in this part may prevent gas from being discharged immediately when the internal pressure of the connector assembly is abnormal, and gas can only be discharged when the internal pressure increases further, considering the material characteristics of the connector assembly and other structures, it is generally unlikely that the connector assembly and other structures will be damaged when the internal pressure value of the connector assembly is only slightly higher than the predetermined pressure value.
[0046] In a further technical solution, a gas retention groove is recessed on the outer surface of the connector body. The number of gas retention grooves is the same as the number of pressure relief channels. The gas retention grooves are connected to the corresponding pressure relief channels and the outer side of the connector body.
[0047] As the dimensions of the pressure relief section and the engagement cavity gradually decrease along the direction from the connecting section toward the pressure relief section, the opening of the gas retention groove and the inner wall of the heat sink are both inclined, so that the gas discharged from the gas retention groove can push the heat sink to move along the length of the connector body, thereby enabling the timely movement of the heat sink and ensuring timely pressure relief.
[0048] The gas retention groove is equivalent to enlarging the end size of the third section away from the second section, so that the amount of gas discharged acts on the heat sink per unit time and the air flow is greater, thereby generating greater thrust, realizing more effective movement of the heat sink, and ensuring timely pressure relief.
[0049] In a further technical solution, at least one annular groove is provided on the outer surface of the connector body, and an annular seal is provided in the annular groove; A portion of the annular seal protrudes from the annular groove.
[0050] The annular seal is initially fixed by the annular groove. Part of the annular seal protrudes from the annular groove. On the one hand, it can improve the sealing effect, restrict gas from leaking out between the joint body and the heat sink, reduce the amount of gas leakage or prevent gas leakage. On the other hand, it can prevent the heat sink from moving upward easily through friction with the heat sink, and prevent gas from being discharged directly through the gas retention groove without obstruction due to the movement of the heat sink.
[0051] In a further technical solution, at least one of the annular grooves is disposed above the gas retention groove along the gas flow direction within the venting orifice.
[0052] For ease of understanding and explanation, the direction of gas flow within the vent hole will be used to indicate the direction from the connecting section to the pressure relief section.
[0053] Considering the gas flow direction within the vent, the gas generally moves upward after being discharged through the gas retention groove. Therefore, the position of the annular groove is designed in this section to restrict the upward leakage of gas.
[0054] A further technical solution involves the heat sink comprising a heat sink body and a plurality of heat sink fins disposed on the heat sink body, the heat sink fins extending radially along the heat sink body. This arrangement can further increase the heat dissipation area and improve heat dissipation efficiency.
[0055] In a further technical solution, a heat-conducting layer is provided between the connector body and the heat dissipation component.
[0056] The thermal conductive layer allows the heat conducted to the connector body to be transferred to the heat dissipation component through thermal conduction, thereby increasing the cooling rate of the connector body and extending its service life.
[0057] A further technical solution is that, in a direction perpendicular to the length of the connector body, the projected portion of the heat sink is located on the side where the projection of the pressure relief section is opposite to the projection of the connecting section.
[0058] This part is actually designed so that the heat sink protrudes upwards in the length direction of the connector body compared to the pressure relief section. On the one hand, this can increase the heat exchange efficiency, and on the other hand, it can fix the silicone tube in the circumferential direction without hindering the installation and removal of the silicone tube.
[0059] In a further technical solution, at least two tangential planes are provided on the outer surface of the connector body.
[0060] By setting the cut-edge plane, a flat and stable clamping surface can be provided for the wrench or similar mounting device, allowing such devices to apply torque better during operation and effectively preventing slippage. This is especially suitable for situations where the pressure relief section is set as a truncated cone.
[0061] In a further technical solution, the connector body includes two connected connector sub-bodies, which are symmetrically arranged in a direction perpendicular to the length direction of the connector body.
[0062] In this section, the connector body is designed with a split structure, which facilitates the installation of sealing components and the processing of the connector body.
[0063] A compressor is also provided herein, which includes an air inlet and an air outlet, and the air inlet and the air outlet are respectively connected to an air inlet connector and an air outlet connector assembly, wherein the air outlet connector assembly is selected from the connector assembly in any of the above embodiments.
[0064] It should be noted that the connector assembly can be used not only in compressors but also in other existing devices. For ease of understanding and explanation, this application will use the connector assembly in a compressor as an example.
[0065] In a further technical solution, the compressor also includes a silicone tube connected to the connector body; Along the length of the connector body, the silicone tube is attached to the end face of the heat sink.
[0066] The silicone tube is an existing feature. The heat sink in this part can interact with the silicone tube. On the one hand, the silicone tube restricts the upward movement of the heat sink. On the other hand, the heat sink restricts the movement of the silicone tube in the circumferential direction of the connector body.
[0067] It should be noted that the heat sink does not need to contact the silicone tube in the circumferential direction of the connector body.
[0068] An oxygen generator is also provided herein, including the compressor in any of the above embodiments.
[0069] It should be noted that the compressor can be used not only in oxygen generators but also in other existing devices. For ease of understanding and explanation, this application will use the application of the compressor in an oxygen generator as an example.
[0070] In a further technical solution, the oxygen generator also includes at least one cooling fan, with the air outlet of the cooling fan facing the heat sink.
[0071] The cooling fan is an existing feature. The heat conducted to the connector assembly is transferred to the heat sink through thermal conduction. With the help of the cooling fan, the heat dissipation speed of the heat sink can be increased, thereby quickly reducing the temperature of the connector assembly. This, in turn, reduces the temperature of the compressor exhaust port, ultimately improving the adsorption efficiency of the oxygen generator's molecular sieve and extending the service life of the oxygen generator.
[0072] In summary, to effectively utilize the remaining space inside the oxygen concentrator and to improve heat dissipation efficiency and rapidly reduce the intake air temperature, this application, considering the overall heat dissipation layout of the oxygen concentrator and focusing on the compressor outlet where heat generation and transfer are greatest, adopts a novel compressor outlet connector that combines heat dissipation and pressure relief functions to replace the existing connector that only meets basic exhaust requirements. This new connector not only fulfills the basic exhaust function but also provides heat dissipation and safe pressure relief. Without sacrificing compressor performance or increasing structural costs, by improving the existing compressor exhaust connector and utilizing the oxygen concentrator's existing cooling centrifugal fan, the connector possesses excellent heat dissipation characteristics, thereby reducing the intake air temperature of the sieve barrel. Furthermore, it prevents the danger of continuously excessive internal pressure in the pipeline, ultimately improving the oxygen production efficiency and safety of the oxygen concentrator. Therefore, the improvement in this application has practical economic benefits and broad application prospects, demonstrating outstanding practical innovation significance.

[0078] The working principle and advantages of this invention are as follows: When in use, the connector assembly connects to the compressor exhaust port to discharge high-pressure gas into the relevant gas path. Specifically, normal exhaust is completed through the vent hole, at which time the connector assembly is in an open state, and the sealing component blocks the pressure relief channel, allowing high-pressure gas to be discharged only through the vent hole. When the pressure inside the vent hole exceeds the rated value, the force on the sealing component gradually increases due to the high temperature and pressure. When the pressure exceeds the compressor's safety threshold, the sealing component will move to release the blockage of the pressure relief channel, allowing the pressure relief channel to open for exhaust. During the normal exhaust and pressure relief operation of the connector assembly, the heat transferred from the high-pressure gas to the connector body can be quickly discharged through the heat sink, preventing the high temperature from affecting the service life of the connector assembly. Through the above settings, on the one hand, the connector assembly has the function of discharging high-pressure gas into the relevant gas path; on the other hand, the connector assembly has the function of timely pressure relief to avoid damage to the compressor and other related equipment; and furthermore, the connector assembly has the characteristic of quickly dissipating heat to extend its own service life.
[0079] In summary, this application, through the cooperation of the connector body, heat dissipation component, and sealing component, not only improves heat dissipation while ensuring product performance, but also has the advantages of compact structure and controllable cost. Furthermore, it provides a guarantee for safe use by users through timely pressure relief. Attached Figure Description

[0082] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.
[0083] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.
[0084] See Figures 1-12 A connector assembly includes a connector body 1, a heat sink 2, and a sealing component 3; The connector body 1 has a venting inner hole 11 and at least one pressure relief channel 12 communicating with the venting inner hole 11 and the outside of the connector body 1; The sealing element 3 is movably installed in each of the pressure relief channels 12; The heat sink 2 is sleeved on the outside of the connector body 1, and the contact surface between the two serves as a continuous heat conduction interface 10. The connector assembly has both a venting state and a depressurization state: In the venting state, the sealing member 3 prevents the gas entering the venting inner hole 11 from being discharged to the outside of the connector body 1 through the pressure relief channel 12; Under depressurization conditions, some of the gas entering the vent hole 11 is discharged to the outside of the connector body 1 via the depressurization channel 12.
[0085] For ease of explanation and understanding, this application describes the connector assembly as being placed vertically during operation, but it can be adjusted in actual use. The application also describes the connector assembly being used in conjunction with the compressor 8.
[0086] The specific design of the vent hole 11 is based on existing designs.
[0087] The connector body 1 is made of common heat-conducting materials, such as copper alloy and aluminum alloy.
[0088] In some embodiments, the heat sink 2 includes a heat sink body and a plurality of heat sink fins disposed on the heat sink body, the heat sink fins extending radially along the heat sink body. This arrangement can further increase the heat dissipation area and improve heat dissipation efficiency.
[0089] When the connector assembly is in use, the connector body 1 is connected to the exhaust port of the compressor 8 to export high-pressure gas to the relevant gas path. Specifically, the normal exhaust work is completed by the venting inner hole 11. At this time, the connector assembly is in the venting state, and the sealing part 3 blocks the pressure relief channel 12, so that the high-pressure gas can only be discharged through the venting inner hole 11 (ignoring the very small amount of high-pressure gas that may leak out).
[0090] When the pressure inside the vent hole 11 exceeds the rated value (e.g., 250 kPa), the force on the sealing component 3 gradually increases due to the high temperature and high pressure. When it exceeds the safety threshold of the compressor 8, the sealing component 3 will move to release the blockage on the pressure relief channel 12, allowing the pressure relief channel 12 to open and exhaust. When this application is applied to the oxygen generator 9, the timely pressure relief operation can safely protect the valves, pipelines and other structures.
[0091] During the normal venting and depressurization operation of the connector assembly, the heat transferred from the high-pressure gas to the connector body 1 can be quickly discharged through the heat sink 2 due to the setting of the heat sink 2, so as to avoid the service life of the connector assembly being affected by high temperature.
[0092] With the above configuration, on the one hand, the connector assembly has the function of exporting high-pressure gas to the relevant gas circuit; on the other hand, the connector assembly has the function of timely depressurization to avoid damage to compressor 8 and other related equipment; furthermore, the connector assembly has the characteristic of quickly dissipating heat to extend its own service life.
[0093] It should be emphasized that, taking the application of this application to compressor 8 and compressor 8 to oxygen concentrator 9 as an example, this application only improves the existing exhaust connector. While retaining the function of the exhaust connector to discharge high-pressure gas from inside compressor 8, it achieves the two important effects of reducing the outlet temperature of compressor 8 and safe pressure relief. Moreover, it does not require increasing the internal space size of oxygen concentrator 9, nor does it require changing the internal component layout of oxygen concentrator 9. It has strong practicality and reliability.
[0094] The continuous thermal interface 10 ensures heat dissipation due to its continuity.
[0095] To further aid in understanding the advantages of this application, the following is added: First of all, it should be noted that in the sieve barrel of oxygen generator 9, temperature has a critical impact on the adsorption efficiency of molecular sieve. When the inlet temperature is too high, the oxygen concentration will drop as the machine runs, and may even drop to the level of an alarm. In order to reduce the intake air temperature, two main aspects are considered: compressor 8 and intake piping. Since there are significant limitations in cooling compressor 8, existing technologies mainly take measures on the intake piping, including extending the heat dissipation coil and increasing the speed of cooling fan 7. Extending the heat dissipation coil requires increasing the internal space of the oxygen generator 9 and significantly increasing structural costs. Furthermore, due to the large temperature difference between the gas at the end of the heat dissipation coil and the outlet of the compressor 8, condensation is easily formed, which can severely affect the use of the molecular sieve. In contrast, this application avoids the problems caused by extending the heat dissipation coil. While increasing the speed of the cooling fan 7 can temporarily improve heat dissipation efficiency, it will accelerate the aging of electronic components inside the fan and increase noise. In contrast, this application avoids the problems caused by increasing the speed of the cooling fan 7.
[0096] See Figures 1-5 In this embodiment, the connector body 1 includes a connecting section 13 and a pressure relief section 14 connected to each other, and the pressure relief channel 12 is disposed in the pressure relief section 14; Along the direction from the connecting section 13 toward the pressure relief section 14, the size of the pressure relief section 14 gradually decreases; The heat sink 2 has a locking cavity (not shown in the figure) for engaging with the pressure relief section 14, and the locking contact surface of the two serves as the continuous heat conduction interface 10. Along the direction from the connecting section 13 toward the pressure relief section 14, the size of the engagement cavity gradually decreases.
[0097] In some embodiments, the outer surface of the connecting section 13 is provided with threads 16 for engaging with the air outlet on the compressor 8.
[0098] In some embodiments, the connector body 1 includes a mating section 15 connected to the side of the pressure relief section 14 away from the connecting section 13, and the mating section 15 is used to connect to the silicone tube described below.
[0099] In some embodiments, the pressure relief section 14 may be considered as a truncated cone.
[0100] Through the size settings in this embodiment, during the installation of the heat sink 2, the pressure relief section 14 gradually restricts the downward movement of the heat sink 2, so that the heat sink 2 is fixed while having movable characteristics, which facilitates the operation of moving the heat sink 2.
[0101] It should be noted that the connection between connecting section 13 and pressure relief section 14 is used as an example for explanation. The connection between other structures can be explained in the same way: the connection between connecting section 13 and pressure relief section 14 can be an integral, non-removable connection, or it can be a detachable connection, such as a threaded connection. This application does not limit these specific connection methods and can adjust them according to the actual situation.
[0102] See Figure 4 In this embodiment, at least two pressure relief channels 12 are provided; Each of the pressure relief channels 12 is evenly distributed in a circular pattern around the axis of the connector body 1.
[0103] When there is only one pressure relief channel 12, if it becomes blocked, it may fail to relieve pressure or the pressure relief effect may be less than expected, affecting the timeliness and effectiveness of pressure relief. However, by increasing the number of pressure relief channels 12, this situation can be avoided. In addition, the pressure relief efficiency can be increased to a certain extent.
[0104] See Figure 4 In this embodiment, the pressure relief channel 12 is configured as two.
[0105] The prerequisite for pressure relief is that the sealing component 3 releases the blockage of the pressure relief channel 12. This requires the pressure inside the connector assembly to reach a certain level. If there are too many pressure relief channels 12, the pressure inside the pressure relief channel 12 will decrease if the amount of gas entering the vent hole 11 remains unchanged. This will cause the sealing component 3 to be unable to move as expected, affecting the timeliness of pressure relief. By limiting the pressure relief channel 12 to two, the risk of being unable to relieve pressure can be reduced, and the impact on the timeliness of pressure relief can also be reduced.
[0106] See Figure 4 In this embodiment, the pressure relief channel 12 includes a first section 121, a second section 122 and a third section 123 connected in sequence. The first section 121 is connected to the vent hole 11, and the third section 123 is connected to the outside of the connector body 1. During depressurization, the high-pressure gas enters the second section 122 through the first section 121 and is discharged to the outside of the connector body 1 through the third section 123, forming a gas flow path; In the depressurized state, the sealing element 3 is located in a clearance portion in the second section 122, which is located outside the gas flow path; In the non-depressurized state, the sealing element 3 is located in the second section 122 and blocks the gas flow path.
[0107] This embodiment defines the structural composition of the pressure relief channel 12. When opening the pressure relief channel 12, it can be designed and opened in sections to adapt to diverse needs.
[0108] The sealing element 3 can be installed in the first segment 121, the second segment 122, or the third segment 123, depending on the actual situation. This application describes the sealing element 3 as being installed in the second segment 122.
[0109] The pressure relief channel 12 may include a fourth segment and more segments; this application describes a three-segment pressure relief channel 12.
[0110] See Figures 6-8 In this embodiment, the length direction of the second segment 122 is parallel to the length direction of the connector body 1; And / or, the length direction of the first segment 121 is perpendicular to the length direction of the connector body 1; And / or, the length direction of the third segment 123 is perpendicular to the length direction of the connector body 1; And / or, the sealing element 3 is disposed within the second segment 122.
[0111] Taking the example of the length direction of the second segment 122 being parallel to the length direction of the connector body 1, the effects of other similar examples are explained: Compared to the case where there is an angle between the length direction of the second segment 122 and the length direction of the connector body 1, the vertical arrangement adopted in this embodiment can reduce the space occupied by the second segment 122 in the radial direction of the connector body 1, thereby reducing the space occupied by this application in the radial direction of the connector body 1. Taking the application of this application for use in the compressor 8 as an example, it can adapt to the compact space layout inside the compressor 8.
[0112] The length of the second segment 122 is parallel to the length of the connector body 1. In addition to the above effects, it also facilitates the vertical movement of the sealing component 3, especially its downward repositioning, so as to promptly seal the pressure relief channel 12.
[0113] In this embodiment, the sealing element 3 is disposed within the second segment 122; The cross-sectional dimensions of the first segment 121 and the third segment 123 are both larger than the cross-sectional dimensions of the sealing member 3, so as to restrict the sealing member 3 from entering the first segment 121 and the third segment 123.
[0114] The first section 121 is the gas inlet section, the third section 123 is the gas outlet section, and the second section 122 is the gas delivery section. The sealing element 3 is located in the second section 122. During certain time periods, the sealing element 3 needs to perform the operation of restricting gas from entering the third section 123.
[0115] To facilitate understanding, the movement path of the sealing component 3 is illustrated below: Vertically, from bottom to top, there are three positions: a first position, a second position, and a third position. When the connector assembly is not working, the sealing component 3 is in the first position. When the connector assembly is working normally, the sealing component 3 moves upward to the second position. When a problem occurs in the connector assembly causing an increase in its internal pressure, the sealing component 3 continues to move upward to the third position. In the second position, the sealing component 3 prevents gas from entering the third segment 123. For example, the sealing component 3 can directly block the opening where the third segment 123 connects to the second segment 122. When the sealing component 3 continues to move upward to the third position, it cannot completely block the opening where the third segment 123 connects to the second segment 122. For example, the sealing component 3 can be completely above the opening where the third segment 123 connects to the second segment 122.
[0116] The first position mentioned above can be regarded as the bottom area of the second segment 122.
[0117] In some embodiments, when the pressure in the oxygen generator 9 pipeline reaches 170 kPa, the plug 3 moves into the second position.
[0118] In some embodiments, the second segment 122 has a smooth inner wall.
[0119] In some embodiments, the size of the second segment 122 gradually decreases from bottom to top.
[0120] The size limitation in this embodiment prevents the sealing element 3 from entering the first segment 121 and the third segment 123, thereby ensuring the continuous operation of the sealing element 3 and the reliability of this application.
[0121] To facilitate understanding of the cross-sectional dimension settings in this embodiment, an example is provided here. Other dimension settings in this application can be understood by referring to this description: Here, the first segment 121 is set to be cylindrical with a longitudinal section radius of A, and the sealing component 3 is set to be a sphere with a sphere radius of B, where B equals A.
[0122] See Figures 6-8 In this embodiment, the sealing element 3 is disposed within the second segment 122; The opening portion of the second segment 122 near the end of the first segment 121 is not connected to the first segment 121, thereby restricting the sealing member 3 from entering the first segment 121.
[0123] It should be noted that when the connector assembly is used vertically, the sealing element 3 is more likely to enter the first section 121 than the third section 123.
[0124] This embodiment provides a second method for restricting the sealing member 3 from entering the first segment 121. Here, the cross-sectional dimensions of the first segment 121, the second segment 122, and the sealing member 3 are all the same. When the opening of the second segment 122 near the end of the first segment 121 is not connected to the first segment 121, the cross-sectional dimension of the area in the opening of the second segment 122 near the end of the first segment 121 that allows the sealing member 3 to pass through is smaller than the cross-sectional dimension of the sealing member 3, thereby restricting the sealing member 3 from entering the first segment 121, thus ensuring the continuous operation of the sealing member 3 and ensuring the reliability of this application.
[0125] In this embodiment, the pressure relief channel 12 includes at least one arc-shaped channel (not shown in the figures). At least one portion of the inner wall of the arc-shaped channel is provided as a limiting part to restrict the sealing member 3 from entering the venting inner hole 11.
[0126] In some embodiments, the protrusions on the inner wall of the arcuate channel may also restrict the sealing element 3 from entering the outside of the connector body 1.
[0127] This embodiment provides another configuration for the pressure relief channel 12. The arc-shaped channel reduces the obstruction to the gas and improves the effect of gas discharge through the pressure relief channel 12.
[0128] This description focuses on the pressure relief channel 12, which includes only one arc-shaped channel. The inner wall of this arc-shaped channel is partially protruding, thereby restricting the sealing element 3 from entering the venting inner hole 11 through this protrusion, thus ensuring the continuous operation of the sealing element 3 and guaranteeing the reliability of this application.
[0129] In some embodiments, the pressure relief channel 12 includes at least two sequentially connected arc-shaped channels.
[0130] See Figures 6-8 In this embodiment, the sealing element 3 is configured as a spherical structure.
[0131] In some embodiments, the sealing element 3 is a steel ball. During the depressurization phase, the high-pressure gas causes the steel ball to move upward against gravity. After the depressurization phase ends, the steel ball returns to its original position due to gravity. The sealing element 3 can also be an elastic element, which returns to its original position using its own tension, specifically referring to a spring structure. One end of this elastic element is fixed, which also limits the range of movement of the elastic element, thereby simplifying the structure of the depressurization channel 12 and reducing costs.
[0132] The spherical structure reduces the friction between the sealing element 3 and the inner wall of the pressure relief channel 12, allowing the sealing element 3 to move in a timely manner and improving the timeliness of pressure relief.
[0133] In some other embodiments, the sealing element 3 may take other shapes, which are not limited here.
[0134] See Figures 6-8 In this embodiment, under ventilation conditions, the heat sink 2 blocks the opening of the pressure relief channel 12 near the outside of the connector body 1; Under depressurization conditions, the heat sink 2 and the opening of the depressurization channel 12 near the outside of the connector body 1 gradually separate.
[0135] In this embodiment, the heat dissipation structure (heat sink 2) and the pressure relief structure (pressure relief channel 12) work synergistically, linking the heat dissipation and pressure relief processes. Specifically, the heat sink 2 blocks the air inlet of the pressure relief channel 12, allowing the venting inner hole 11 to function normally; when the heat sink 2 unblocks the air inlet, the pressure relief channel 12 performs its pressure relief operation normally; and the heat sink 2, through its contact with the connector body 1, continuously performs heat dissipation while achieving the above functions, and also provides a sealing function. Based on this, the venting, pressure relief, and heat dissipation functions of the connector assembly are linked. In some cases, the movement of the heat sink 2 facilitates gas leakage and causes deformation of the silicone tube, after which the silicone tube resets and pushes the heat sink 2 back to its original position. The heat sink 2 can also reset solely by gravity.
[0136] The opening of the pressure relief channel 12 near the outside of the connector body 1 refers to the end opening of the third section 123 away from the second section 122.
[0137] Under pressure relief conditions, the heat sink 2 and the pressure relief channel 12 gradually separate from the opening on the outside of the connector body 1. They may eventually separate completely or not completely.
[0138] There is generally a gap between the sealing element 3 and the inner wall of the pressure relief channel 12. Gas will be discharged through this gap, causing gas leakage. If a sealing structure such as a sealing ring is set on the sealing element 3, it will affect the movement of the sealing element 3 during the pressure relief process.
[0139] By using a heat sink 2 to block the opening of the pressure relief channel 12 near the outside of the connector body 1, the amount of gas leakage during non-pressure relief periods can be reduced.
[0140] It should be noted that although the arrangement of the heat sink 2 in this embodiment may cause the gas to be unable to be discharged immediately when the internal pressure of the connector assembly is abnormal, and it is necessary to wait for the internal pressure to increase further before it can be discharged, considering the material characteristics of the connector assembly and other structures, it is generally unlikely that the internal pressure value of the connector assembly will be slightly higher than the predetermined pressure value, which will cause damage to the connector assembly and other structures.
[0141] See Figure 3 In this embodiment, a gas retention groove 17 is recessed on the outer surface of the connector body 1. The number of gas retention grooves 17 is the same as the number of pressure relief channels 12. The gas retention grooves 17 are connected to the corresponding pressure relief channels 12 and the outer side of the connector body 1.
[0142] As the dimensions of the pressure relief section 14 and the engagement cavity gradually decrease along the direction from the connecting section 13 toward the pressure relief section 14, the opening of the gas retention groove 17 and the inner wall of the heat sink 2 are both inclined, so that the gas discharged from the gas retention groove 17 can push the heat sink 2 to move in the length direction of the connector body 1, thereby realizing the timely movement of the heat sink 2 and ensuring timely pressure relief.
[0143] The gas retention groove 17 is equivalent to expanding the end size of the third section 123 away from the second section 122, so that the amount of gas discharged acts on the heat sink 2 per unit time and the flow rate of gas is greater, thereby generating greater thrust and realizing more effective movement of the heat sink 2, ensuring timely pressure relief.
[0144] See Figure 4 , Figure 8 In this embodiment, at least one annular groove 18 is provided on the outer surface of the connector body 1, and an annular sealing element 4 is provided in the annular groove 18. A portion of the annular seal 4 protrudes from the annular groove 18.
[0145] In some embodiments, the annular seal 4 is configured as a sealing ring.
[0146] The annular seal 4 is initially fixed by the annular groove 18. Part of the annular seal 4 protrudes from the annular groove 18. On the one hand, it can improve the sealing effect, restrict gas from leaking out between the connector body 1 and the heat sink 2, reduce the amount of gas leakage or avoid gas leakage. On the other hand, it can prevent the heat sink 2 from moving upward easily by friction with the heat sink 2, and prevent gas from being discharged directly through the gas retention groove 17 without obstruction due to the movement of the heat sink 2.
[0147] See Figure 8 In this embodiment, at least one of the annular grooves 18 is disposed above the gas retention groove 17 along the gas flow direction within the venting inner hole 11.
[0148] For ease of understanding and explanation, the direction of gas flow within the vent hole 11 is referred to as the direction from the connecting section 13 toward the pressure relief section 14.
[0149] Considering the gas flow direction within the vent hole 11, the gas generally moves upward after being discharged through the gas retention groove 17. Therefore, in this embodiment, the position of the annular groove 18 is set to restrict the upward leakage of gas.
[0150] In some embodiments, the annular groove 18 is provided as a single one, and this annular groove 18 is positioned above the gas retention groove 17.
[0151] In some embodiments, two annular grooves 18 are provided, and along the gas flow direction in the venting inner hole 11, the two annular grooves 18 are respectively provided on both sides of the gas retention groove 17.
[0152] In this embodiment, a heat-conducting layer (not shown in the figure) is provided between the connector body 1 and the heat sink 2, and the heat-conducting layer is provided at the continuous heat-conducting interface 10.
[0153] In some embodiments, the thermally conductive layer is composed of thermally conductive silicone grease.
[0154] The heat-conducting layer enables the heat conducted to the connector body 1 to be transferred to the heat sink 2 through heat conduction, thereby increasing the cooling rate of the connector body 1 and extending its service life.
[0155] See Figures 6-8 In this embodiment, in the direction perpendicular to the length direction of the connector body 1, the portion of the projection of the heat sink 2 is located on the side of the projection of the pressure relief section 14 that is opposite to the projection of the connecting section 13.
[0156] In this embodiment, the heat sink 2 is arranged to protrude upwards from the pressure relief section 14 in the length direction of the connector body 1. On the one hand, this can increase the heat exchange efficiency, and on the other hand, it can fix the silicone tube in the circumferential direction without hindering the installation and disassembly of the silicone tube.
[0157] See Figures 1-2 In this embodiment, at least two tangential planes 19 are provided on the outer surface of the connector body 1.
[0158] In some embodiments, the installation process of the connector body 1 is as follows: the connecting section 13 is screwed into the air outlet of the compressor 8 using a wrench and reaches the designated installation position.
[0159] By setting the cut-edge plane 19, a flat and stable clamping surface can be provided for the wrench or similar mounting device, so that such devices can apply torque better during operation and effectively avoid slippage. This is especially suitable for situations where the pressure relief section 14 is set as a truncated cone (in which case the outer surface of the pressure relief section 14 is curved).
[0160] In some embodiments, the tangential plane 19 is separated from the annular groove 18.
[0161] See Figure 4 In this embodiment, the connector body 1 includes two connected connector sub-body 101, which are symmetrically arranged in a direction perpendicular to the length direction of the connector body 1.
[0162] In this embodiment, the connector body 1 is configured as a split structure, which facilitates the installation of the sealing component 3 and the processing of the connector body 1.
[0163] In some embodiments, after the sealing component 3 is installed, a special high-temperature anaerobic adhesive is applied to the mating surface of the connector body 101, and then the two connector bodies 101 are tightly bonded along the mating surface to form the connector body 1.
[0164] The relationship between the above structure and the connector body 101 can be adjusted according to specific circumstances. For example, for the pressure relief channel 12, in one case, the pressure relief channel 12 is set as a single channel and located on one of the connector bodies 101; in another case, the pressure relief channel 12 is set as a single channel and is surrounded by two connector bodies 101; in yet another case, the pressure relief channel 12 is set as two channels and the two pressure relief channels 12 are respectively set on two connector bodies 101; and in yet another case, the pressure relief channel 12 is set as two channels and the two pressure relief channels 12 are surrounded by two connector bodies 101.
[0165] See Figure 9 A compressor 8 is also provided herein, comprising an air inlet and an air outlet, wherein the air inlet and the air outlet are respectively connected to an air inlet connector 6 and an air outlet connector assembly, wherein the air outlet connector assembly is selected from the connector assembly in any of the above embodiments.
[0166] It should be noted that the connector assembly can be used not only in compressor 8 but also in other existing devices. For ease of understanding and explanation, this application will use the connector assembly in compressor 8 as an example.
[0167] See Figure 9 In this embodiment, the compressor 8 also includes a silicone tube (not shown in the figure) connected to the connector body 1. Along the length of the connector body 1, the silicone tube is attached to the end face of the heat sink 2.
[0168] The silicone tube is an existing feature. In this embodiment, the heat sink 2 and the silicone tube can interact. On the one hand, the silicone tube restricts the heat sink 2 from moving upward. On the other hand, the heat sink 2 restricts the movement of the silicone tube in the circumferential direction of the connector body 1.
[0169] It should be noted that the heat sink 2 may not contact the silicone tube in the circumferential direction of the connector body 1.
[0170] The heat sink 2 serves as a heat dissipation structure and also helps to prevent gas leakage during non-depressurization stages. Moving the heat sink 2 facilitates gas leakage, and the movement causes deformation of the silicone tube. Subsequently, the silicone tube resets, pushing the heat sink 2 back to its original position.
[0171] In some embodiments, the silicone tube is separated from the heat sink 2.
[0172] In some embodiments, the silicone tube is sleeved on the mating section 15 and abuts against the heat sink 2.
[0173] See Figure 10 , Figure 11 An oxygen generator is also provided herein, including the compressor 8 of any of the above embodiments.
[0174] It should be noted that the compressor 8 can be used not only in the oxygen generator 9 but also in other existing devices. For ease of understanding and explanation, this application will use the compressor 8 in the oxygen generator 9 as an example.
[0175] See Figure 10 , Figure 11 In this embodiment, the oxygen generator 9 further includes at least one cooling fan 7, the air outlet of which is directed toward the heat sink 2.
[0176] The cooling fan 7 is an existing configuration. The heat conducted to the connector assembly is transferred to the heat sink 2 through thermal conduction. With the help of the cooling fan 7, the heat dissipation speed of the heat sink 2 can be improved, thereby achieving the purpose of quickly reducing the temperature of the connector assembly, thereby reducing the temperature of the exhaust port of the compressor 8, and ultimately improving the adsorption efficiency of the molecular sieve of the oxygen generator 9 and extending the service life of the oxygen generator 9.
[0177] In summary, in order to effectively utilize the remaining internal space of the oxygen concentrator 9 and to improve heat dissipation efficiency and rapidly reduce the intake air temperature, this application, considering the heat dissipation layout of the entire oxygen concentrator 9 and focusing on the compressor 8 outlet, which generates the most heat (exhaust temperature can reach 130℃) and transfers the most heat, adopts a new compressor 8 outlet connector that combines heat dissipation and pressure relief functions to replace the existing connector that only meets basic exhaust requirements. This connector not only takes into account the basic exhaust function of the connector but also provides heat dissipation and safe pressure relief functions. Without sacrificing the performance of the compressor 8 or adding significant additional structural costs, by improving the existing compressor 8 exhaust connector and utilizing the original cooling centrifugal fan of the oxygen concentrator 9, the connector has excellent heat dissipation characteristics, thereby reducing the intake air temperature of the sieve barrel. In addition, it can prevent the danger of continuously excessive internal pressure in the pipeline, ultimately improving the oxygen production efficiency and safety of the oxygen concentrator 9. Therefore, the improvement of this application has practical economic benefits and broad application prospects, and its practical innovation significance is outstanding.

They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
