Description

Technical Field

[0001] This application belongs to the technical field of medical devices, specifically relating to an oxygen generation module and a diffusion oxygen generator. Background Technology

[0002] A diffusion oxygen generator is a device that separates oxygen from the air through the principle of physical adsorption. It is widely used in fields such as medical care and high-altitude environments.

[0003] Currently, diffusion oxygen generators typically include a casing, a compressor located inside the casing, a cooling system located inside the casing, and a molecular sieve located inside the casing. The casing has an intake chamber connected to the compressor's inlet, the compressor's outlet connected to the cooling system's inlet, and the cooling system's outlet connected to the molecular sieve. When the diffusion oxygen generator is working, air from outside the casing enters the compressor through the intake chamber and the compressor's inlet, allowing the compressor to compress the air. The compressed air then enters the cooling system through the compressor's outlet to cool it. The cooled compressed air then enters the molecular sieve to separate oxygen from the compressed air. Finally, the separated oxygen is transported to the room through a delivery pipeline to increase the indoor oxygen concentration.

[0004] However, because the compressor is located inside the casing and generates a significant amount of heat during operation, it is prone to overheating. This affects the compressor's operating power, which in turn impacts the oxygen production efficiency of the diffusion oxygen generator. Furthermore, it also shortens the compressor's lifespan, leading to a higher failure rate. Additionally, after prolonged operation, the cooling system's temperature also rises, affecting its cooling effect on the compressed air and consequently impacting the oxygen production efficiency of the diffusion oxygen generator. Utility Model Content

[0005] This application provides an oxygen generation module to ensure the oxygen production efficiency of a diffusion oxygen generator and reduce its failure rate.

[0006] The technical solution adopted in this application is as follows:

[0007] An oxygen generation module, comprising:

[0008] The housing has an air intake chamber and an installation chamber inside, and the housing is provided with an air inlet communicating with the air intake chamber;

[0009] A compressor, at least a portion of which is located in the mounting cavity, the compressor having an intake pipe communicating with its own intake port, the intake pipe being located in the intake cavity;

[0010] The first exhaust component is disposed in the air inlet chamber, and the air outlet of the first exhaust component is connected to the mounting chamber.

[0011] A condenser is disposed in the air inlet chamber, the air inlet of the condenser is connected to the air outlet of the compressor, and the condenser is located between the air inlet of the first exhaust component and the air inlet.

[0012] By adopting the above technical solution, since the first exhaust component is located in the air inlet chamber and its outlet is connected to the mounting chamber, air in the air inlet chamber can enter the mounting chamber under the action of the first exhaust component. This allows the air entering the mounting chamber to dissipate heat from the compressor located in the mounting chamber, thereby improving the compressor's heat dissipation effect and reducing its operating temperature. This ensures the compressor operates within a relatively optimal temperature range, maintaining its operating power and thus guaranteeing the oxygen production efficiency of the diffusion oxygen generator equipped with the oxygen generation module of this application. Simultaneously, it avoids... This avoids the risk of compressor damage due to high temperatures, thus reducing the failure rate of the oxygen generation module and the diffusion oxygen generator equipped with the oxygen generation module of this application. On the other hand, after the first exhaust component delivers air from the intake chamber to the mounting chamber, it creates a negative pressure in the intake chamber, allowing air from outside the casing to enter the intake chamber through the air inlet, thereby improving the intake efficiency of the casing and ensuring the intake volume of the compressor, which in turn ensures the oxygen production efficiency of the oxygen generation module and the oxygen production efficiency of the oxygen generation module equipped with the oxygen generation module of this application.

[0013] Furthermore, since the condenser is located between the air inlet and the air outlet of the first exhaust component, the air entering the air intake chamber through the air inlet can be transported to the mounting chamber by the first exhaust component after passing through the condenser. This allows the airflow in the air intake chamber to cool the condenser, thereby improving the cooling effect of the condenser on the compressed air. This further improves the oxygen generation efficiency of the oxygen generation module and the oxygen production efficiency of the diffusion oxygen generator equipped with the oxygen generation module of this application.

[0014] Optionally, the compressor has a cooling fan located on the side of the compressor, and the first exhaust component communicates with the mounting cavity on the side of the cooling fan away from the compressor.

[0015] By adopting the above technical solution, since the connection between the first exhaust component and the mounting cavity is located on the side of the cooling fan away from the compressor, the air delivered to the mounting cavity by the first exhaust component can flow towards the side where the compressor is located under the action of the cooling fan. This allows more air to flow towards the compressor, further improving the heat dissipation effect on the compressor and further reducing the compressor temperature, enabling the compressor to operate within a better temperature range, thereby reducing the compressor failure rate and ensuring the compressor's working efficiency, and thus further ensuring the oxygen production efficiency of the oxygen generation module. On the other hand, it also allows a stable airflow to be formed in the mounting cavity, avoiding turbulence and reducing the noise generated by the oxygen generation module during operation. This improves the operating noise of the diffusion oxygen generator equipped with the oxygen generation module of this application, thereby enhancing the user experience.

[0016] Optionally, the housing has an air outlet communicating with the mounting cavity, the first exhaust component communicating with the mounting cavity and the air outlet are respectively located on two opposite cavity walls of the mounting cavity, and the first exhaust component communicating with the mounting cavity and the air outlet are both located on the same side of the cooling fan.

[0017] By adopting the above technical solution, since the connection position of the first exhaust component with the mounting cavity and the air outlet are respectively located on two opposite cavity walls of the mounting cavity, and the connection position of the first exhaust component with the mounting cavity and the air outlet are both located on the same side of the cooling fan, on the one hand, the air entering the mounting cavity will be discharged to the outside of the casing through the air outlet after passing through the compressor twice, thereby further improving the heat dissipation efficiency of the compressor, thus further ensuring the working power of the compressor, and further ensuring the oxygen production efficiency of the oxygen generation module; on the other hand, the air needs to change direction when it is discharged from the mounting cavity, so as to reduce the kinetic energy of the air discharged from the mounting cavity through the air outlet, thereby reducing the noise generated when the air is discharged from the mounting cavity through the air outlet, and further reducing the noise generated when the oxygen generation module is working and the noise generated when the diffusion oxygen generator equipped with the oxygen generation module of this application is working, thereby further improving the user experience.

[0018] Optionally, the cavity wall of the mounting cavity is provided with a baffle plate located at the air outlet, the baffle plate being located on the side of the air outlet away from the compressor.

[0019] By adopting the above technical solution, since the baffle is located on the side of the air outlet away from the compressor, it can, on the one hand, block the air so that all the air passing through the compressor can be discharged from the casing through the air outlet. This allows more relatively cool air to pass through the compressor, improving the heat dissipation effect and further ensuring the compressor's operating power and reducing its failure rate. On the other hand, the air flowing towards the air outlet can impact the baffle, reducing the air's kinetic energy and further reducing the noise generated when the air is discharged from the casing through the air outlet. This further improves the noise generated when the oxygen generation module is working, thus enhancing the user experience.

[0020] Optionally, the oxygen generation module further includes a filter element for filtering air and disposed in the air intake chamber. The filter element divides the air intake chamber into a first chamber and a second chamber. The first chamber is connected to the air inlet. The air inlet of the air intake pipe is connected to the filter element. The air intake pipe is located in the first chamber and is connected to the second chamber through the filter element.

[0021] By adopting the above technical solution, since the filter divides the air intake chamber into a first chamber and a second chamber, the first chamber is connected to the air inlet, and the air intake pipe is located in the first chamber and connected to the second chamber through the filter. This allows air from outside the casing to enter the first chamber through the air inlet, then pass through the filter into the second chamber, where the filter filters the air. The air entering the second chamber then passes through the filter again before entering the air intake pipe, where it is filtered a second time. This improves the air filtration effect, enhancing the cleanliness of the air entering the compressor. It prevents the compressor from drawing in insufficiently filtered air, which could lead to impurity accumulation, noise, and reduced compressor lifespan. This further reduces the compressor failure rate, thereby reducing the failure rate of the oxygen generation module and the diffusion oxygen generator equipped with the oxygen generation module described in this application.

[0022] Optionally, the air intake chamber is provided with an air intake hood communicating with the air inlet and a second exhaust component located inside the air intake hood. The air intake hood is provided with an exhaust port opposite to the air inlet, and the air outlet of the second exhaust component is opposite to the exhaust port.

[0023] By adopting the above technical solution, since the second exhaust component is located inside the air inlet shroud, it can transport air from outside the casing to the air intake chamber. This avoids turbulence in the air intake chamber, which could increase noise during the operation of the oxygen generation module, thus improving the user experience. Furthermore, it prevents filtered air from being drawn away by the second exhaust component, reducing the filter load and extending its lifespan. Additionally, the second exhaust component increases the air intake volume of the air intake chamber, improving the compressor's air intake and heat dissipation, thereby further ensuring the oxygen generation efficiency of the oxygen generation module.

[0024] Furthermore, since the air inlet hood is equipped with an exhaust port opposite to the air inlet, and the air outlet of the second exhaust component is also opposite to the exhaust port, the air transported by the second exhaust component can be directly discharged through the exhaust port. This increases the smoothness of airflow and avoids turbulence in the air inlet chamber, ensuring smooth air intake and reducing noise generated by the oxygen generation module during operation. On the other hand, it also allows the air transported by the second exhaust component to be directly blown onto the condenser and the first exhaust component, improving the cooling effect on the condenser and the air intake smoothness of the first exhaust component, thereby further improving the heat dissipation efficiency of the compressor.

[0025] Optionally, the housing includes a base and a housing detachably connected to the base, the housing and the base together forming the mounting cavity, the compressor is disposed on the base, and at least a portion of the compressor extends to the outside of the base, a first partition is disposed inside the housing, the first partition and the housing together forming the air intake cavity, and the condenser and the first exhaust fan are both disposed on the first partition.

[0026] By adopting the above technical solution, since the housing is removably connected to the base and the compressor is located on the base, when replacing or repairing the compressor, it is only necessary to separate the housing from the base to expose the compressor to the operator's line of sight, thereby achieving the effect of facilitating the replacement or repair of the compressor.

[0027] Furthermore, since the housing is equipped with a first partition, and the condenser and the first exhaust fan are both located on the first partition, when the housing is separated from the base, the condenser and the first exhaust fan will separate along with the housing and the base, thereby providing a sufficiently large space for the replacement or maintenance of the compressor, so as to further facilitate the replacement or maintenance of the compressor.

[0028] Furthermore, since at least part of the compressor extends outside the base, the volume of the housing can be reduced, which facilitates the miniaturization of the housing design, and in turn, facilitates the miniaturization of the oxygen generation module design.

[0029] Optionally, a second partition is provided inside the housing, and the second partition and the housing together form a receiving cavity. The oxygen generation module also includes an adsorption cylinder located in the receiving cavity, and the air inlet of the adsorption cylinder is connected to the air outlet of the condenser.

[0030] By adopting the above technical solution, since the second partition and the shell together form a receiving cavity, and the adsorption cylinder is located in the receiving cavity, the adsorption cylinder will separate from the base along with the shell when the shell is separated from the base, so as to provide a sufficiently large space for the replacement or maintenance of the compressor, thereby further achieving the effect of facilitating the replacement or maintenance of the compressor.

[0031] Optionally, the first partition is provided with an air connector that can be connected to the air inlet of the compressor, and the air outlet of the air inlet pipe is connected to the air connector.

[0032] By adopting the above technical solution, since the first partition is provided with an air connector that can connect with the air inlet of the compressor, and the air outlet of the air inlet pipe is connected to the air connector, that is, the air inlet pipe is connected to the compressor through the air connector. Thus, when the housing is separated from the base, the air inlet pipe can be separated from the compressor at the same time. When the housing is installed on the base, the air inlet pipe can be connected to the air inlet of the compressor through the air connector at the same time. This avoids the situation where the air inlet pipe needs to be disassembled and installed separately when the housing is disassembled and installed, thereby reducing the difficulty of disassembling and installing the housing, and further improving the efficiency of replacing or repairing the compressor.

[0033] Optionally, the housing extends with an edge, the edge has a positioning part, and the base has a mating part that engages with the positioning part.

[0034] By adopting the above technical solution, since a positioning part is provided along the edge and a mating part is provided on the base to engage with the positioning part, the connection stability between the housing and the base is increased, thereby increasing the stability of the oxygen generation module. On the other hand, the positioning part and the mating part can be used to guide the housing, thereby reducing the assembly difficulty of the housing. At the same time, it ensures that after the housing is installed on the base, the air connector can be connected to the air inlet of the compressor.

[0035] Optionally, the compressor includes a base, a stationary scroll disposed on the base, a moving scroll disposed on the base and capable of moving relative to the stationary scroll, and a motor disposed on the base for driving the moving scroll, wherein at least a portion of the motor extends outside the base.

[0036] By adopting the above technical solution, since at least a portion of the motor extends to the outside of the base, the motor is located at the bottom of the compressor, so that the weight of the compressor is concentrated in its lower middle part, thereby reducing the shaking and noise generated when the compressor is working, increasing the working stability of the compressor and reducing the noise generated when the oxygen generation module is working.

[0037] Optionally, the base has an exposed area protruding from the outer peripheral surface of the motor, the base is provided with a positioning body, and the exposed area is provided with a shock-absorbing structure that plugs into and cooperates with the positioning body.

[0038] By adopting the above technical solution, since the base has an exposed area protruding from the outer circumference of the motor, the base is equipped with a positioning body, and the exposed area is equipped with a shock-absorbing structure that plugs into the positioning body, the compressor can be installed on the base by supporting the exposed area with the shock-absorbing structure. On the other hand, when disassembling and assembling the compressor, only a force parallel to the vertical direction needs to be applied to the compressor, so as to facilitate the disassembly and assembly of the compressor. Furthermore, it can also reduce the vibration transmitted from the compressor to the base, thereby reducing the vibration generated by the oxygen generation module when it is working, and thus increasing the stability of the oxygen generation module when it is working.

[0039] Optionally, the positioning body has a insertion cavity, and the shock-absorbing structure includes a spring, an isolator located at one end of the spring, a shock absorber located at the other end of the spring, and a bolt threaded to the base. The bolt passes through the shock absorber, the spring, and the isolator in sequence. At least a portion of the shock absorber extends into the insertion cavity. The isolator is located between the exposed area and the spring and has a hardness less than that of the base.

[0040] By adopting the above technical solution, since the shock absorption structure includes a spring, an isolator located at one end of the spring, a shock absorber located at the other end of the spring, and a bolt threaded to the base, the spring and shock absorber can absorb the vibration generated when the compressor is working, thereby reducing the amount of vibration transmitted from the compressor to the base and increasing the stability of the oxygen generation module.

[0041] Furthermore, since the bolts pass through the shock absorber, spring, and isolator in sequence, and the bolt threads are connected to the base, the shock absorber, spring, and isolator are then installed on the base to increase the stability of the damping structure.

[0042] Furthermore, since at least part of the shock absorber extends into the insertion cavity, the damping structure and the positioning body are connected and engaged, so that the cavity wall of the insertion cavity can be used to limit the damping body, thereby increasing the stability and service life of the damping body.

[0043] Furthermore, since the isolator is located between the exposed area and the spring and its hardness is less than that of the base, the isolator can be used to isolate the spring and the base, thereby avoiding noise generated by direct contact and friction between the base and the spring, and further reducing the noise generated when the oxygen generation module is working.

[0044] Optionally, the housing includes a casing having a top cover, the top cover being provided with a filter element.

[0045] By adopting the above technical solution, since the shell has a top cover and the top cover is equipped with a filter element, when the top cover is separated from the shell, the filter element can be separated from the shell along with the top cover, so as to facilitate the removal of the filter element. At the same time, placing the filter element on the top cover can also increase the stability of the filter element.

[0046] This application also provides a diffusion oxygen generator to ensure the oxygen production efficiency of the diffusion oxygen generator and reduce the failure rate of the diffusion oxygen generator.

[0047] A diffusion oxygen generator includes an integrated box and an oxygen generation module as described above. The oxygen generation module is located inside the integrated box. The integrated box is provided with an air inlet channel that can communicate with the air inlet and an air outlet channel that can communicate with the air outlet.

[0048] By adopting the above technical solution, since the diffuse oxygen generator in this application uses the aforementioned oxygen generation module, the heat dissipation effect of the compressor is improved, so that the compressor can operate within a better temperature range. On the one hand, the working power of the compressor is guaranteed, thereby ensuring the oxygen production efficiency of the diffuse oxygen generator. On the other hand, the compressor is prevented from malfunctioning due to high temperature, thereby reducing the failure rate of the diffuse oxygen generator.

[0049] Furthermore, since the integrated box is equipped with an air intake channel that can connect with the air inlet, air from outside the integrated box can enter the air intake chamber through the air intake channel and the air inlet to meet the air intake requirements of the compressor and to dissipate heat from the compressor using the first exhaust component; and since the integrated box is equipped with an air outlet channel that can connect with the air outlet, air discharged through the air outlet can be discharged to the outside of the integrated box through the air outlet channel to ensure that the air inside the casing can be discharged to the outside of the integrated box.

[0050] Optionally, the integrated box includes a bottom shell, a side plate disposed on the side of the bottom shell, and a top plate disposed on the top of the side plate. The housing is disposed on the bottom shell, the air inlet channel is disposed on the side plate, and the air outlet channel is disposed on the side of the bottom shell. The air inlet channel and the air outlet channel are respectively located on opposite sides of the integrated box.

[0051] By adopting the above technical solution, since the integrated box includes a bottom shell, a side plate located on the side of the bottom shell, and a top plate located on the top of the side plate, the integrated box can form a sealed space to protect the oxygen generation module. Furthermore, since the air inlet channel and the air outlet channel are located on opposite sides of the integrated box, the situation where air discharged through the air outlet channel directly enters the interior of the integrated box through the air inlet channel is avoided. This ensures that the air entering the integrated box is relatively low-temperature air, thereby reducing the compressor's intake temperature and improving the compressor's heat dissipation effect, further ensuring the oxygen production efficiency of the diffusion oxygen generator.

[0052] Optionally, the bottom shell is provided with a support plate, the housing is disposed on the support plate, the support plate is provided with a clearance opening corresponding to the air outlet of the compressor and the housing, and the support plate is provided with an air baffle plate located at the clearance opening, and an exhaust hole is provided at the end of the air baffle plate away from the air outlet channel.

[0053] By adopting the above technical solution, since the support plate is provided with a clearance opening corresponding to the compressor and the air outlet of the casing, it is possible to install the casing on the support plate and allow the air discharged through the air outlet to enter the space between the support plate and the bottom shell. Furthermore, since the support plate is provided with an air baffle plate located at the clearance opening, and an exhaust hole is provided at the end of the air baffle plate away from the air outlet channel, the air discharged through the air outlet will pass through the exhaust hole at the end of the air baffle plate away from the air outlet channel and enter the space between the air baffle plate and the bottom shell. The air entering the space between the air baffle plate and the bottom shell will eventually be discharged through the air outlet channel, thereby extending the air flow path and reducing the kinetic energy of the air when it is discharged through the air outlet channel. This reduces the noise generated by the diffusion oxygen generator during operation and improves the user experience.

[0054] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0055] 1. The oxygen generation module of this application includes a housing, a compressor, a first exhaust fan, and a condenser. The housing has an intake chamber and a mounting chamber. The housing has an air inlet communicating with the intake chamber. At least a portion of the compressor is located in the mounting chamber. The compressor has an intake pipe communicating with its own air inlet, which is located in the intake chamber. The first exhaust fan is located in the intake chamber, and its outlet is communicating with the mounting chamber. The condenser is located in the intake chamber, and its inlet is communicating with the compressor's outlet. The condenser is located between the inlet of the first exhaust fan and the air inlet. This allows air in the intake chamber to enter the mounting chamber under the action of the first exhaust fan, so that the air entering the mounting chamber can dissipate heat from the compressor located in the mounting chamber, thereby improving the compressor's heat dissipation effect and reducing the compressor's operating temperature. The operating temperature is designed to ensure that the compressor operates within a relatively optimal temperature range, thereby guaranteeing the compressor's operating power and thus the oxygen production efficiency of the diffusion oxygen generator equipped with the oxygen generation module of this application. This also prevents the compressor from being easily damaged due to high temperatures, reducing the failure rate of both the oxygen generation module and the diffusion oxygen generator. Furthermore, the first exhaust component delivers air from the intake chamber to the mounting chamber, creating a negative pressure in the intake chamber. This allows air from outside the casing to enter the intake chamber through the air inlet, improving the intake efficiency of the casing and ensuring the compressor's air intake volume. This, in turn, guarantees the oxygen production efficiency of both the oxygen generation module and the oxygen generation module of this application.

[0056] 2. The compressor in this application has a cooling fan located on the side of the compressor. The first exhaust fan communicates with the mounting cavity on the side of the cooling fan away from the compressor. This allows the air delivered to the mounting cavity by the first exhaust fan to flow towards the side where the compressor is located under the action of the cooling fan. This enables more air to flow towards the compressor, further improving the cooling effect and reducing the compressor temperature. This allows the compressor to operate within an optimal temperature range, reducing the compressor's failure rate and ensuring its efficiency, thereby guaranteeing the oxygen production efficiency of the oxygen generation module. Furthermore, it creates a stable airflow within the mounting cavity, preventing turbulence and reducing the noise generated by the oxygen generation module. This improves the noise level of the diffusion oxygen generator equipped with the oxygen generation module of this application, enhancing the user experience.

[0057] 3. The housing in this application has an air outlet communicating with the mounting cavity. The communication position of the first exhaust component with the mounting cavity and the air outlet are respectively located on two opposite cavity walls of the mounting cavity, and the communication position of the first exhaust component with the mounting cavity and the air outlet are both located on the same side of the cooling fan. This allows the air entering the mounting cavity to be discharged to the outside of the housing through the air outlet after passing through the compressor twice, thereby further improving the heat dissipation efficiency of the compressor and ensuring the working power of the compressor, thus further ensuring the oxygen production efficiency of the oxygen generation module. On the other hand, it requires the air to change direction when it is discharged from the mounting cavity, thereby reducing the kinetic energy of the air discharged from the mounting cavity through the air outlet, thereby reducing the noise generated when the air is discharged from the mounting cavity through the air outlet, and further reducing the noise generated when the oxygen generation module is working and the noise generated when the diffusion oxygen generator with the oxygen generation module of this application is installed is working, thereby further improving the user experience.

[0082] Since the first exhaust component 3 is located in the air inlet chamber 11 and its outlet is connected to the mounting chamber 12, air in the air inlet chamber 11 can enter the mounting chamber 12 under the action of the first exhaust component 3. This allows the air entering the mounting chamber 12 to dissipate heat from the compressor 2 located in the mounting chamber 12, thereby improving the heat dissipation effect of the compressor 2 and reducing its operating temperature. This ensures that the compressor 2 can operate within a relatively optimal temperature range, guaranteeing its operating power and thus ensuring the oxygen production efficiency of the diffusion oxygen generator equipped with the oxygen generation module 100 of this application. Simultaneously, it avoids the compressor 2 from easily experiencing high temperatures. The high temperature can cause the compressor 2 to be easily damaged, thereby reducing the failure rate of the oxygen generation module 100 and the failure rate of the diffusion oxygen generator equipped with the oxygen generation module 100 of this application; on the other hand, after the first exhaust component 3 delivers the air in the intake chamber 11 to the mounting chamber 12, it can create a negative pressure in the intake chamber 11, so that the air outside the casing 1 can enter the intake chamber 11 through the air inlet 111, thereby improving the intake efficiency of the casing 1, thereby ensuring the intake volume of the compressor 2, and further ensuring the oxygen production efficiency of the oxygen generation module 100 and the oxygen production efficiency of the oxygen generation module 100 of this application.

[0083] Furthermore, since the condenser 4 is located between the air inlet and the air inlet 111 of the first exhaust fan 3, the air entering the air intake chamber 11 through the air inlet 111 can be transported to the mounting chamber 12 by the first exhaust fan 3 after passing through the condenser 4. This allows the airflow in the air intake chamber 11 to cool the condenser 4, thereby improving the cooling effect of the condenser 4 on the compressed air. This further improves the oxygen generation efficiency of the oxygen generation module 100 and the oxygen production efficiency of the diffusion oxygen generator equipped with the oxygen generation module 100 of this application.

[0084] This application does not specifically limit the relative positional relationship between the air intake chamber 11 and the mounting chamber 12. Preferably, the air intake chamber 11 is located above the mounting chamber 12, so that the compressor 2 is located below the air intake chamber 11. This lowers the center of gravity of the oxygen generation module 100, thereby increasing the stability of the oxygen generation module 100. It also makes better use of vertical space, reducing the area occupied by the oxygen generation module 100. In other embodiments, the mounting chamber 12 may be located above the air intake chamber 11, or it may be located on the side of the air intake chamber 11.

[0085] This application does not specifically limit the structure of the condenser 4; preferably, refer to... Figures 5 to 7 The condenser 4 is a coil-type condenser to ensure effective cooling of the compressed air and facilitate its installation. In other embodiments, the condenser 4 can also be a water-cooled cooler, a plate-fin heat exchanger, or other structures capable of cooling compressed air.

[0086] This application does not specify the number of first exhaust components 3. Preferably, two first exhaust components 3 are provided to further improve the heat dissipation effect on the compressor 2, and at the same time, to further improve the air intake efficiency of the air inlet 111. Of course, in other embodiments, the number of first exhaust components 3 can also be set to other quantities.

[0087] This application does not specifically limit the structure of the first exhaust component 3. Preferably, the first exhaust component 3 is a vortex fan, so as to facilitate the installation and arrangement of the first exhaust component 3 and to facilitate the miniaturization design of the oxygen generation module 100. In other embodiments, the first exhaust component 3 can also be an axial fan or other structure capable of transporting air.

[0088] This application does not specify the heat dissipation method of the first exhaust component 3 for the compressor 2. Preferably, refer to Figures 5 to 7 The compressor 2 has a cooling fan 22, which is located on the side of the compressor 2. The first exhaust component 3 communicates with the mounting cavity 12 on the side of the cooling fan 22 away from the compressor 2.

[0089] It is understandable that the air inlet of the cooling fan 22 is located on the side of the cooling fan 22 away from the compressor 2, while the air outlet of the cooling fan 22 is located on the side of the cooling fan 22 facing the compressor 2, so that the air delivered to the mounting cavity 12 by the first exhaust component 3 can move to the side of the compressor 2 away from the cooling fan 22 under the action of the cooling fan 22.

[0090] Since the connection between the first exhaust component 3 and the mounting cavity 12 is located on the side of the cooling fan 22 away from the compressor 2, the air delivered to the mounting cavity 12 by the first exhaust component 3 can flow towards the side where the compressor 2 is located under the action of the cooling fan 22. This allows more air to flow towards the compressor 2, further improving the heat dissipation effect on the compressor 2, thereby further reducing the temperature of the compressor 2 and enabling the compressor 2 to operate within a better temperature range. This further reduces the failure rate of the compressor 2 and ensures its working efficiency, thus further ensuring the oxygen production efficiency of the oxygen generation module 100. On the other hand, it allows a stable airflow to be formed in the mounting cavity 12, avoiding turbulence and reducing the noise generated by the oxygen generation module 100 during operation. This improves the operating noise of the diffusion oxygen generator equipped with the oxygen generation module 100 of this application, thereby enhancing the user experience.

[0091] This application does not specify the air outlet method of the mounting cavity 12; preferably, refer to... Figure 7 The housing 1 has an air outlet 141 that communicates with the mounting cavity 12. The first exhaust component 3 is located on two opposite cavity walls of the mounting cavity 12, and the first exhaust component 3 is located on the same side of the cooling fan 22.

[0092] It is understandable that the first exhaust component 3 is connected to the mounting cavity 12 at the top of the mounting cavity 12, and the air outlet 141 is connected to the mounting cavity 12 at the bottom of the mounting cavity 12.

[0093] Since the first exhaust component 3 is connected to the mounting cavity 12 and the air outlet 141 are located on two opposite cavity walls of the mounting cavity 12, and the first exhaust component 3 is connected to the mounting cavity 12 and the air outlet 141 are both located on the same side of the cooling fan 22, on the one hand, the air entering the mounting cavity 12 will be discharged to the outside of the housing 1 through the air outlet 141 after passing through the compressor 2 twice, so as to further improve the heat dissipation efficiency of the compressor 2, thereby further ensuring the working power of the compressor 2, and further ensuring the oxygen production efficiency of the oxygen generation module 100; on the other hand, the air needs to change direction when it is discharged from the mounting cavity 12, so as to reduce the kinetic energy of the air discharged from the mounting cavity 12 through the air outlet 141, thereby reducing the noise generated when the air is discharged from the mounting cavity 12 through the air outlet 141, and further reducing the noise generated when the oxygen generation module 100 is working and the noise generated when the diffused oxygen generator with the oxygen generation module 100 of this application is installed is working, so as to further improve the user experience.

[0094] In other embodiments, the air outlet 141 may be located on the side of the mounting cavity 12 and on the side of the compressor 2 away from the cooling fan 22, or the first exhaust member 3 and the mounting cavity 12 are connected at the same side of the cooling fan 22 and the air outlet 141 is located on the side of the mounting cavity 12.

[0095] Furthermore, refer to Figure 8 The cavity wall of the mounting cavity 12 is provided with a baffle plate 142 located at the air outlet 141. The baffle plate 142 is located on the side of the air outlet 141 away from the compressor 2. On the one hand, the baffle plate 142 can block the air so that all the air passing through the compressor 2 can be discharged from the housing 1 through the air outlet 141. This allows more relatively cool air to pass through the compressor 2, thereby improving the heat dissipation effect of the compressor 2, further ensuring the working power of the compressor 2 and further reducing the failure rate of the compressor 2. On the other hand, the air flowing towards the air outlet 141 can impact the baffle plate 142 to reduce the kinetic energy of the air, thereby further reducing the noise generated when the air is discharged from the housing 1 through the air outlet 141. This further improves the noise generated when the oxygen generation module 100 is working, thereby improving the user experience.

[0096] This application does not impose specific limitations on the arrangement of the baffle 142. Preferably, the baffle 142 extends vertically to reduce the manufacturing difficulty of the baffle 142. In other embodiments, the baffle 142 can also be inclined from bottom to top towards the direction of the compressor 2, so that the baffle 142 can guide the air, thereby allowing all the air to be discharged through the air outlet 141 under the action of the baffle 142.

[0097] In other embodiments, the communication position between the first exhaust component 3 and the mounting cavity 12 can be set on the side of the compressor 2 away from the cooling fan 22. At this time, the air inlet of the cooling fan 22 is located on the side of the cooling fan 22 closer to the compressor 2, and the air outlet of the cooling fan 22 is located on the side of the cooling fan 22 away from the compressor 2, so that the air delivered to the mounting cavity 12 by the first exhaust component 3 can move to the side of the compressor 2 away from the first exhaust component 3 under the action of the cooling fan 22; or the cooling fan 22 can be omitted and the air outlet of the first exhaust component 3 can be tilted towards the compressor 2 to reduce the manufacturing cost of the oxygen generation module 100.

[0098] In a preferred embodiment, refer to Figures 5 to 7The oxygen generation module 100 also includes a filter element 5, which is used to filter air and is located in the air intake chamber 11. The filter element 5 divides the air intake chamber 11 into a first chamber and a second chamber. The first chamber is connected to the air inlet 111. The air inlet of the air intake pipe 21 is connected to the filter element 5. The air intake pipe 21 is located in the first chamber and is connected to the second chamber through the filter element 5.

[0099] It is understandable that the first exhaust component 3 and the condenser component 4 are both located in the first cavity.

[0100] Because the filter element 5 divides the air intake chamber 11 into a first chamber and a second chamber, the first chamber is connected to the air inlet 111, and the air intake pipe 21 is located in the first chamber and connected to the second chamber through the filter element 5, the air outside the casing 1 enters the first chamber through the air inlet 111 and then passes through the filter element 5 into the second chamber, so that the filter element 5 filters the air. The air entering the second chamber passes through the filter element 5 again and enters the air intake pipe 21, so that the filter element 5 filters the air again, thereby improving the air filtration effect and improving the cleanliness of the air entering the compressor 2. This avoids the compressor 2 from sucking in insufficiently filtered air, which would cause impurities to accumulate, resulting in noise from the compressor 2 and affecting the service life of the compressor 2. This further reduces the failure rate of the compressor 2, thereby further reducing the failure rate of the oxygen generation module 100 and the failure rate of the diffusion oxygen generator equipped with the oxygen generation module 100 of this application.

[0101] This application does not specifically limit the structure of the filter element 5. Preferably, the filter element 5 includes a filter element 5 disposed in the air intake chamber 11 and a filter screen wrapped around the outside of the filter frame. The filter frame is provided with an air inlet that connects with the air inlet of the air intake pipe 21, so that the air entering the compressor 2 needs to be filtered three times by the filter screen, so as to further improve the cleanliness of the air entering the compressor 2, thereby further reducing the noise generated by the compressor 2 during operation and further reducing the failure rate of the compressor 2.

[0102] It is understood that in this embodiment, the second cavity is located on top of the first cavity to facilitate the assembly and disassembly of the filter element 5.

[0103] In other embodiments, the filter element 5 includes a filter box made of metal mesh and filter cotton disposed inside the filter box. The air inlet of the air inlet pipe 21 is connected to the filter box to achieve the same effect of filtering the air entering the compressor 2. In this embodiment, the second chamber can be located at the bottom of the first chamber or the second chamber can be located inside the first chamber.

[0104] This application does not specify the installation position of the filter element 5; preferably, refer to... Figure 5The housing 1 includes a housing 13, which has a top cover 131. The top cover 131 is provided with a filter element 5. When the top cover 131 is separated from the housing 13, the filter element 5 can be separated from the housing 13 along with the top cover 131, so as to facilitate the removal of the filter element 5. At the same time, placing the filter element 5 on the top cover 131 can also increase the stability of the filter element 5.

[0105] This application does not specify the method of fixing the filter element 5 to the top cover 131. It can be fixed to the top cover 131 by screws or other fasteners, or it can be fixed to the top cover 131 by a snap-fit ​​structure.

[0106] In other embodiments, the filter element 5 may be fixedly installed at the top opening of the housing 13.

[0107] This application does not specify the air intake method for the air intake chamber 11; preferably, refer to... Figures 5 to 7 The air intake chamber 11 is provided with an air intake hood 112 that communicates with the air inlet 111 and a second exhaust component 113 located inside the air intake hood 112. The air intake hood 112 is provided with an exhaust port that is opposite to the air inlet 111, and the air outlet of the second exhaust component 113 is opposite to the exhaust port.

[0108] Since the second exhaust fan 113 is located inside the air inlet shroud 112, it can transport air from outside the housing 1 to the air inlet chamber 11. This avoids turbulence in the air inlet chamber 11, which could increase noise during the operation of the oxygen generation module 100, thus improving the user experience. Furthermore, it prevents the air filtered by the filter element 5 from being drawn away by the second exhaust fan 113, reducing the filtration burden on the filter element 5 and extending its service life. Additionally, by setting the second exhaust fan 113, the air intake volume of the air inlet chamber 11 can be increased, ensuring the air intake volume of the compressor 2 and improving the heat dissipation of the compressor 2, thereby further ensuring the oxygen production efficiency of the oxygen generation module 100.

[0109] Furthermore, since the air inlet shroud 112 is provided with an exhaust port that is opposite to the air inlet 111, and the air outlet of the second exhaust component 113 is opposite to the exhaust port, the air transported by the second exhaust component 113 can be directly discharged through the exhaust port. This increases the smoothness of airflow and avoids turbulence in the air inlet chamber 11, ensuring the smooth air intake of the air inlet chamber 11 and the noise generated when the oxygen generation module 100 is working. On the other hand, it also allows the air transported by the second exhaust component 113 to be directly blown towards the condenser 4 and the first exhaust component 3, thereby improving the cooling effect on the condenser 4 and improving the smoothness of air intake of the first exhaust component 3, further improving the heat dissipation efficiency of the compressor 2.

[0110] Preferably, the air outlet of the second exhaust component 113 is arranged opposite to the air inlet of the first exhaust component 3. On the one hand, this can improve the air delivery efficiency of the first exhaust component 3, thereby improving the heat dissipation effect on the compressor 2. On the other hand, it can ensure that the air discharged through the exhaust port flows towards the first exhaust component 3 and passes through the condenser 4, thereby improving the cooling effect on the condenser 4 and thus improving the oxygen production efficiency of the oxygen generation module 100.

[0111] This application does not specify the number of second exhaust components 113. Preferably, there are two second exhaust components 113 arranged opposite each other, that is, the air inlets of the two second exhaust components 113 are arranged opposite each other to further improve the air intake efficiency of the air inlet 111. Of course, in other embodiments, other numbers of second exhaust components 113 may be provided.

[0112] This application does not specifically limit the structure of the second exhaust component 113. Preferably, the second exhaust component 113 is a vortex fan, so as to facilitate the installation and arrangement of the second exhaust component 113 and to facilitate the miniaturization design of the oxygen generation module 100. In other embodiments, the second exhaust component 113 may also be an axial fan or other structure capable of transporting air.

[0113] In other embodiments, the second exhaust element 113 may be omitted so that air from outside the housing 1 can enter the intake chamber 11 by utilizing the air pressure difference between the intake chamber 11 and the outside of the housing 1.

[0114] This application does not specifically limit the structure of the casing 1; preferably, refer to... Figures 1 to 5 The housing 1 includes a base 14 and a housing 13 that is removably connected to the base 14. The housing 13 and the base 14 together form an installation cavity 12. The compressor 2 is disposed on the base 14, and at least a portion of the compressor 2 extends to the outside of the base 14. A first partition 132 is disposed inside the housing 13. The first partition 132 and the housing 13 together form an air intake cavity 11. The condenser 4 and the first exhaust 3 are both disposed on the first partition 132.

[0115] It is understood that the first partition 132 is provided with a hole structure corresponding to the air outlet 141 of the first exhaust component 3 so as to realize the air outlet of the first exhaust component 3 is connected to the mounting cavity 12; the base 14 is provided with a hole structure corresponding to the compressor 2 so that at least part of the compressor 2 can extend to the outside of the base 14.

[0116] Since the housing 13 is removably connected to the base 14 and the compressor 2 is located on the base 14, when replacing or repairing the compressor 2, the housing 13 can be separated from the base 14 to expose the compressor 2 to the operator's line of sight, thereby facilitating the replacement or repair of the compressor 2.

[0117] Furthermore, since the housing 13 has a first partition 132 inside, the condenser 4 and the first exhaust fan 3 are both located on the first partition 132. Therefore, when the housing 13 is separated from the base 14, the condenser 4 and the first exhaust fan 3 will separate along with the housing 13 and the base 14, thereby providing a sufficiently large space for the replacement or maintenance of the compressor 2, so as to further facilitate the replacement or maintenance of the compressor 2.

[0118] Furthermore, since at least a portion of the compressor 2 extends outside the base 14, the volume of the housing 1 can be reduced, thereby facilitating the miniaturization of the housing 1 and consequently facilitating the miniaturization of the oxygen generation module 100.

[0119] Furthermore, refer to Figure 7 The housing 13 has a second partition 133 inside, and the second partition 133 and the housing 13 together form a accommodating cavity. The oxygen generation module 100 also includes an adsorption cylinder 6 located in the accommodating cavity, and the air inlet of the adsorption cylinder 6 is connected to the air outlet of the condenser 4.

[0120] It should be noted that the above-mentioned "the first partition 132 and the housing 13 together form the air intake cavity 11" and "the second partition 133 and the housing 13 together form the accommodating cavity" means that the first partition 132 and the second partition 133 together divide the internal space of the housing 13 into the air intake cavity 11, the mounting cavity 12 and the accommodating cavity.

[0121] Since the second partition 133 and the housing 13 together form a receiving cavity, the adsorption cylinder 6 is located in the receiving cavity. As a result, when the housing 13 is separated from the base 14, the adsorption cylinder 6 will separate from the housing 13 and the base 14, so as to provide a sufficiently large space for the replacement or maintenance of the compressor 2, thereby further achieving the effect of facilitating the replacement or maintenance of the compressor 2.

[0122] Preferably, the accommodating cavity is located on the side of the mounting cavity 12 and the air intake cavity 11 to reduce the height of the oxygen generation module 100.

[0123] The better one is to refer to Figure 7 The base 14 is provided with a surrounding rib 143 that surrounds the adsorption cylinder 6, so that the surrounding rib 143 can be used to limit the adsorption cylinder 6 to increase the stability of the adsorption cylinder 6, and at the same time, the surrounding rib 143 can also be used to increase the structural strength of the base 14.

[0124] This application does not specify the connection method between the intake pipe 21 and the intake port of the compressor 2. Preferably, refer to Figure 5 and Figure 6 The first partition 132 is provided with an air connector 134 that can be connected to the air inlet of the compressor 2, and the air outlet of the air inlet pipe 21 is connected to the air connector 134.

[0125] Understandably, the outlet of the intake pipe 21 is connected to the intake port of the compressor 2 via the air connector 134.

[0126] Since the first partition 132 is provided with an air connector 134 that can connect with the air inlet of the compressor 2, and the air outlet of the air inlet pipe 21 is connected to the air connector 134, that is, the air inlet pipe 21 is connected to the compressor 2 through the air connector 134. Thus, when the housing 13 is separated from the base 14, the air inlet pipe 21 can be separated from the compressor 2 at the same time. When the housing 13 is installed on the base 14, the air inlet pipe 21 can be connected to the air inlet of the compressor 2 through the air connector 134 at the same time. This avoids the situation where the air inlet pipe 21 needs to be disassembled and installed separately when the housing 13 is disassembled and installed, thereby reducing the difficulty of disassembling and installing the housing 13 and further improving the efficiency of replacing or repairing the compressor 2.

[0127] In other embodiments, the air connector 134 can be omitted, and the air outlet of the air inlet pipe 21 can be directly fitted onto the outside of the air inlet of the compressor 2, and the first partition 132 can be provided with a hole structure for the air inlet pipe 21 to pass through.

[0128] This application does not specifically limit the connection method between the condenser 4 and the compressor 2. Preferably, the first partition 132 is provided with a through hole, through which a connecting pipe 41 is inserted. One end of the connecting pipe 41 is fitted outside the air outlet of the compressor 2, and the other end of the connecting pipe 41 is fitted outside the air inlet of the condenser 4, so as to realize the connection between the condenser 4 and the compressor 2. When the compressor 2 is replaced or repaired, the connecting pipe 41 needs to be separated from the condenser 4 so that the housing 13 can be removed from the base 14. In other embodiments, the connection method between the condenser 4 and the compressor 2 can also refer to the connection method between the air inlet pipe 21 and the compressor 2.

[0129] Furthermore, refer to Figure 4 and Figure 7 The housing 13 extends along an edge 135, and the edge 135 is provided with a positioning part 136. The base 14 is provided with a mating part 144 that is inserted and engaged with the positioning part 136.

[0130] It is understood that the edge 135 is located at the bottom edge of the housing 13 and extends outward from the housing 13.

[0131] Since a positioning part 136 is provided along the edge 135 and a mating part 144 is provided on the base 14 to engage with the positioning part 136, the connection stability between the housing 13 and the base 14 is increased, thereby increasing the stability of the oxygen generation module 100. On the other hand, the engagement between the positioning part 136 and the mating part 144 can guide the housing 13, thereby reducing the assembly difficulty of the housing 13. At the same time, it ensures that after the housing 13 is installed on the base 14, the air connector 134 can be connected to the air inlet of the compressor 2.

[0132] Preferably, multiple positioning parts 136 are provided at intervals along the circumference of the housing 13, and multiple mating parts 144 are provided corresponding to the positioning parts 136, so as to increase the number of limiting points on the housing 13 and increase the stability of the housing 13.

[0133] This application does not specifically limit the structure of the positioning part 136 and the mating part 144. Preferably, the positioning part 136 is a hole structure provided along the edge 135, and the mating part 144 is a columnar structure provided on the base 14, with the diameter of the columnar structure gradually decreasing from bottom to top. This achieves both the insertion and mating of the mating part 144 and the positioning part 136, and also allows for fine-tuning of the housing 13 using the mating of the positioning part 136 and the mating part 144, thus facilitating the installation of the housing 13. In other embodiments, the positioning part 136 may also be a columnar structure provided along the edge 135, and the mating part 144 may be a hole structure provided on the base 14.

[0134] Furthermore, refer to Figures 5 to 9 The compressor 2 includes a base 23, a stationary scroll disposed on the base 23, a moving scroll disposed on the base 23 and capable of moving relative to the stationary scroll, and a motor 24 disposed on the base 23 for driving the moving scroll. At least a portion of the motor 24 extends outside the base 14, thereby positioning the motor 24 at the bottom of the compressor 2. This concentrates the weight of the compressor 2 in its lower middle part, thereby reducing the shaking and noise generated during the operation of the compressor 2, increasing the operational stability of the compressor 2, and reducing the noise generated during the operation of the oxygen generation module 100.

[0135] Furthermore, refer to Figures 5 to 9 The base 23 has an exposed area protruding from the outer periphery of the motor 24, and the base 14 is provided with a positioning body 145. The exposed area is provided with a shock-absorbing structure 25 that is inserted and engaged with the positioning body 145.

[0136] Since the base 23 has an exposed area protruding from the outer periphery of the motor 24, the base 14 is provided with a positioning body 145, and the exposed area is provided with a shock-absorbing structure 25 that is inserted and matched with the positioning body 145. Thus, on the one hand, the shock-absorbing structure 25 can be used to support the exposed area to install the compressor 2 on the base 14. On the other hand, when disassembling and assembling the compressor 2, only a force parallel to the vertical direction needs to be applied to the compressor 2 to facilitate the disassembly and assembly of the compressor 2. Furthermore, it can also reduce the vibration transmitted from the compressor 2 to the base 14, thereby reducing the vibration generated when the oxygen generation module 100 is working, and thus increasing the stability of the oxygen generation module 100 during operation.

[0137] Preferably, multiple shock-absorbing structures 25 are arranged at intervals along the circumference of the motor 24, and multiple positioning bodies 145 are arranged corresponding to the shock-absorbing structures 25. Each shock-absorbing structure 25 is inserted and matched with its corresponding positioning body 145 to increase the number of support and fixing points for the compressor 2, thereby increasing the stability of the compressor 2.

[0138] This application does not specifically limit the damping structure 25; however, preferred options are as described above. Figure 9 The positioning body 145 has a plug-in cavity. The shock-absorbing structure 25 includes a spring 251, an isolator 252 located at one end of the spring 251, a shock absorber 253 located at the other end of the spring 251, and a bolt 254 threaded to the base 23. The bolt 254 passes through the shock absorber 253, the spring 251, and the isolator 252 in sequence. At least a portion of the shock absorber 253 extends into the plug-in cavity. The isolator 252 is located between the exposed area and the spring 251 and has a hardness less than that of the base 23.

[0139] It is understandable that both the isolator 252 and the shock absorber 253 have holes through which the bolt 254 passes. The hardness of the isolator 252 is less than that of the base 23 and less than that of the spring 251.

[0140] Since the shock absorption structure 25 includes a spring 251, an isolator 252 located at one end of the spring 251, a shock absorber 253 located at the other end of the spring 251, and a bolt 254 threaded to the base 23, the spring 251 and the shock absorber 253 can absorb the vibration generated when the compressor 2 is working, thereby reducing the amount of vibration transmitted from the compressor 2 to the base 14 and increasing the stability of the oxygen generation module 100.

[0141] Furthermore, since the bolt 254 passes through the shock absorber 253, the spring 251 and the isolator 252 in sequence, and the bolt 254 is threadedly connected to the base 23, the shock absorber 253, the spring 251 and the isolator 252 are installed on the base 23, thereby increasing the stability of the shock absorption structure 25.

[0142] Furthermore, since at least a portion of the shock absorber 253 extends into the insertion cavity, the damping structure 25 and the positioning body 145 are inserted and matched, so that the cavity wall of the insertion cavity can be used to limit the damping body, thereby increasing the stability and service life of the damping body.

[0143] Furthermore, since the isolator 252 is located between the exposed area and the spring 251 and its hardness is less than that of the base 23, the isolator 252 can be used to isolate the spring 251 and the base 23 to avoid the noise generated by the direct contact and friction between the base 23 and the spring 251, thereby further reducing the noise generated when the oxygen generation module 100 is working.

[0144] This application does not specifically limit the structure of the isolator 252. Preferably, the isolator 252 includes a guide section extending into the spring 251 and an isolating section located outside the spring 251. The diameter of the isolating section is larger than the diameter of the guide section and larger than the outer diameter of the spring 251. This increases the connection stability between the isolator 252 and the spring 251, guides the deformation of the spring 251 using the guide section to increase the stability of the spring 251 during deformation, and increases the connection area between the isolator 252 and the bolt 254 to further increase the stability of the isolator 252. In other examples, the guide section can be omitted to reduce the manufacturing cost of the isolator 252.

[0145] The material used to manufacture the isolator 252 is not specifically limited in this application. Preferably, the isolator 252 is made of plastic material to reduce the manufacturing cost of the isolator 252 while ensuring its noise reduction effect on the spring 251 and the base 23. In other embodiments, the isolator 252 may also be made of other materials, such as nylon.

[0146] This application does not specifically limit the structure of the shock absorber 253. Preferably, the shock absorber 253 includes a limiting section extending into the spring 251 and a connecting section located outside the spring 251. The diameter of the connecting section is larger than the diameter of the limiting section and larger than the outer diameter of the spring 251, and the connecting section extends into the insertion cavity. This increases the connection stability between the shock absorber 253 and the spring 251, guides the deformation of the spring 251 using the limiting section to increase the stability of the spring 251 during deformation, and increases the connection area between the shock absorber 253 and the bolt 254 to increase the stability of the shock absorber 253. In other embodiments, the limiting section can be omitted to reduce the manufacturing cost of the shock absorber 253.

[0147] This application does not specifically limit the material used to manufacture the shock absorber 253. Preferably, the shock absorber 253 is made of silicone material, which can improve the shock absorption effect of the shock absorber 253 and increase the friction between the shock absorber 253 and the insertion cavity, thereby increasing the stability of the compressor 2. In other embodiments, the shock absorber 253 may also be made of materials such as nylon.

[0148] In other embodiments, the shock absorber 253, the isolator 252 and the bolt 254 can be omitted, and the insertion cavity can be omitted as well. One end of the spring 251 can be directly fixed to the bottom of the base 23, and the other end of the spring 251 can be sleeved on the outside of the positioning body 145; or the shock absorber 253 can be sleeved on the outside of the positioning body 145.

[0149] In other embodiments, the housing 1 includes a box with an open top and a cover on the top of the box. A support frame is removably connected inside the box. A first partition 132 is provided on the support frame. When the compressor 2 is replaced or repaired, the cover needs to be separated from the box first, and then the support frame can be removed from the box so that the compressor 2 is exposed to the operator's line of sight.

[0150] In a preferred embodiment, refer to Figure 5 and Figure 7 The oxygen generation module 100 also includes a circuit board 7 disposed in the air intake chamber 11. The circuit board 7 is located between the air inlet 111 and the first exhaust member 3, and the circuit board 7 is located on the side of the condenser 4, so that when the air in the air intake chamber 11 flows to the first exhaust member 3, the air can flow through the circuit board 7 to dissipate heat from the circuit board 7 and thereby reduce the temperature of the circuit board 7.

[0151] In a preferred embodiment, refer to Figures 1 to 3 The housing 1 has a first direction and a second direction perpendicular to the first direction. The housing 1 has a first accommodating section and a second accommodating section in the first direction. The width of the first accommodating section is smaller than the width of the second accommodating section. The mounting cavity 12 and the air inlet cavity 11 are both located inside the first accommodating section. The accommodating cavity is located inside the second accommodating section so that the adsorption cylinder 6 can be arranged side by side in the accommodating cavity, thereby facilitating the installation and arrangement of the adsorption cylinder 6. At the same time, a grooved handle 137 is provided on the side of the first accommodating section so that when multiple oxygen generating modules 100 are arranged sequentially in the second direction, the operator's hand can reach into the grooved handle 137 through the space between two adjacent first accommodating sections to apply an upward pulling force to the housing 13, thereby facilitating the disassembly of the housing 13.

[0152] Reference Figures 12 to 15This application also discloses a diffusion oxygen generator, which includes an integrated box 200 and an oxygen generation module 100 as described above. The oxygen generation module 100 is located inside the integrated box 200. The integrated box 200 is provided with an air inlet channel 221 that can communicate with the air inlet 111 and an air outlet channel 211 that can communicate with the air outlet 141.

[0153] Since the diffused oxygen generator in this application uses the aforementioned oxygen generation module 100, the heat dissipation effect on the compressor 2 is improved, so that the compressor 2 can operate within a better temperature range. On the one hand, this ensures the working power of the compressor 2, thereby ensuring the oxygen production efficiency of the diffused oxygen generator. On the other hand, it avoids the compressor 2 from malfunctioning due to high temperature, thereby reducing the failure rate of the diffused oxygen generator.

[0154] Furthermore, since the integrated box 200 is provided with an air intake channel 221 that can communicate with the air inlet 111, the air outside the integrated box 200 can enter the air intake chamber 11 through the air intake channel 221 and the air inlet 111 to meet the air intake requirements of the compressor 2 and to achieve heat dissipation of the compressor 2 by the first exhaust component 3; and since the integrated box 200 is provided with an air outlet channel 211 that can communicate with the air outlet 141, the air discharged through the air outlet 141 can be discharged to the outside of the integrated box 200 through the air outlet channel 211 to ensure that the air inside the casing 1 can be discharged to the outside of the integrated box 200.

[0155] This application does not specify a particular number of oxygen generating modules 100. Preferably, multiple oxygen generating modules 100 are arranged along the second direction to increase the oxygen production efficiency of the diffusion oxygen generator. Of course, in other embodiments, only one oxygen generating module 100 may be provided to reduce the manufacturing cost of the diffusion oxygen generator.

[0156] Furthermore, the integrated box 200 includes a bottom shell 210, a side plate 220 disposed on the side of the bottom shell 210, and a top plate 230 disposed on the top of the side plate 220. The housing 1 is disposed on the bottom shell 210, the air inlet channel 221 is disposed on the side plate 220, and the air outlet channel 211 is disposed on the side of the bottom shell 210. The air inlet channel 221 and the air outlet channel 211 are respectively located on opposite sides of the integrated box 200.

[0157] Since the integrated box 200 includes a bottom shell 210, a side plate 220 located on the side of the bottom shell 210, and a top plate 230 located on the top of the side plate 220, the integrated box 200 can form a sealed space to protect the oxygen generation module 100. Furthermore, since the air inlet channel and the air outlet channel 211 are located on opposite sides of the integrated box 200, the air discharged through the air outlet channel 211 is prevented from directly entering the interior of the integrated box 200 through the air inlet channel 221. This ensures that the air entering the integrated box 200 is relatively cool, thereby reducing the intake temperature of the compressor 2 and improving the heat dissipation effect on the compressor 2, further ensuring the oxygen production efficiency of the diffusion oxygen generator.

[0158] Furthermore, placing the air outlet duct 211 on the side of the bottom shell 210, compared to placing the air outlet duct 211 on the bottom of the bottom shell 210, can extend the air flow path in the integrated box 200, thereby reducing the kinetic energy of the air and thus reducing the noise generated when the air is discharged through the air outlet duct 211.

[0159] Preferably, the air inlet channel 221 is located on the side away from the air inlet 111 to increase the flow path of air when it enters the air intake chamber 11 through the air inlet 111, thereby reducing the noise generated when the diffused oxygen generator is working.

[0160] This application does not specifically limit the formation of the air inlet channel 221 and the air outlet channel 211. Preferably, the air inlet channel 221 is formed by a louver provided on the side plate 220; the air outlet channel 211 is formed by a perforated structure provided on the side of the bottom shell 210, and the perforated structure extends to the side plate 220 or the side plate 220 is designed to avoid the perforated structure. In other embodiments, the air inlet channel 221 may also be formed by a perforated structure provided on the side plate 220, and the air outlet channel 211 may be formed by a louver provided on the side of the bottom shell 210.

[0161] Preferably, the bottom of the bottom shell 210 is provided with multiple rolling wheels 212, and both ends of the bottom shell 210 are provided with handles 213, so as to facilitate the movement of the diffusion oxygen generator and improve the convenience of the diffusion oxygen generator.

[0162] Furthermore, refer to Figure 14 and Figure 15 The bottom shell 210 is provided with a support plate 214, the housing 1 is provided on the support plate 214, the support plate 214 is provided with a clearance opening corresponding to the air outlet 141 of the compressor 2 and the housing 1, and the support plate 214 is provided with an air baffle plate 215 located at the clearance opening, and an exhaust hole 216 is provided at the end of the air baffle plate 215 away from the air outlet channel 211.

[0163] Because the support plate 214 is provided with a clearance opening corresponding to the air outlet 141 of the compressor 2 and the housing 1, the housing 1 can be installed on the support plate 214 and the air discharged through the air outlet 141 can enter the space between the support plate 214 and the bottom shell 210. Furthermore, because the support plate 214 is provided with an air baffle 215 located at the clearance opening, and an exhaust hole 216 is provided at the end of the air baffle 215 away from the air outlet channel 211, the air discharged through the air outlet 141 will pass through the exhaust hole 216 at the end of the air baffle 215 away from the air outlet channel 211 and enter the space between the air baffle 215 and the bottom shell 210. The air entering the space between the air baffle 215 and the bottom shell 210 will eventually be discharged through the air outlet channel 211, thereby extending the air flow path and reducing the kinetic energy of the air when it is discharged through the air outlet channel 211. This reduces the noise generated by the diffused oxygen generator during operation and improves the user experience.

[0164] Preferably, the support plate 214 is provided with a snap-fit ​​hole and a positioning hole, and the base 14 is provided with a positioning post 146 extending into the positioning hole and a snap-fit ​​arm 147 snapped into the snap-fit ​​hole, so as to increase the connection stability between the oxygen generation module 100 and the support plate 214.
