Description

Technical Field

[0001] This application belongs to the technical field of medical devices, specifically relating to a control terminal for a diffusion oxygen concentrator. Background Technology

[0002] A diffusion oxygen generator is a device that increases the oxygen concentration in the environment through diffusion. It is mainly used to improve the overall oxygen content in enclosed spaces or specific scenarios. Its core principle is to separate oxygen in the air through molecular sieve technology and release it into the surrounding air in a diffusion form.

[0003] A diffused oxygen generator typically consists of an outdoor oxygen generator unit and an indoor control terminal. The control terminal can control the start and stop of the oxygen generator unit and provide the oxygen produced by the oxygen generator unit to people indoors through the control terminal.

[0004] Currently, most control terminals on the market are equipped with additional oxygen humidification and air humidification modules. The oxygen humidification module includes a humidification cup located at one end of the control terminal. The humidification cup has an oxygen inlet and an oxygen outlet. Oxygen produced by the oxygen generator enters the humidification cup through the oxygen inlet and comes into contact with the liquid inside the humidification cup before being discharged from the humidification cup through the oxygen outlet. This allows users to inhale the humidified oxygen through a nasal cannula, making the oxygen inhaled by the user more humid and improving the user experience. The air humidification module includes a humidification cup located at the other end of the control terminal and an atomizing plate located in the humidification cup. The atomizing plate can atomize the liquid contained in the humidification cup and spray it out of the humidification cup to increase the humidity of the indoor environment. However, since the humidification cup and the humidifying cup are located at opposite ends of the control terminal, adding liquid to either cup requires moving the water-filling cup to the control terminal and then pouring the liquid into it. This increases the difficulty of adding liquid to the humidification cup. Furthermore, when adding liquid, it is easy for it to spill onto the outside of the humidification cup or the humidifying cup, affecting the cleanliness of the control terminal and potentially damaging its internal circuitry, thus impacting the user experience. Utility Model Content

[0005] This application provides a control terminal for a diffusion oxygen generator, which facilitates the addition of liquid to the control terminal, ensures the cleanliness and service life of the control terminal, and improves the user experience.

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

[0007] A control terminal for a diffusion oxygen generator includes:

[0008] A housing, the interior of which has a mounting cavity;

[0009] A regulating valve, which is connected to the intake pipe and located within the mounting cavity;

[0010] A diffused gas box is disposed in the mounting cavity and connected to the regulating valve. Gas entering the diffused gas box through the regulating valve can be released to the outside of the housing through the diffused gas box.

[0011] A humidifying mist assembly, which is detachably mounted on the side of the housing, and is used to humidify output gas and / or generate atomized liquid.

[0012] By adopting the above technical solution, when the diffusion oxygen generator with the control terminal of this application is working, part of the oxygen produced by the oxygen generator flows directly into the diffusion gas box after passing through the regulating valve, so that the oxygen in the diffusion gas box is released into the indoor environment by diffusion. The remaining oxygen after passing through the regulating valve enters the humidification component, so that the humidification component humidifies the oxygen. The humidified oxygen is discharged from the humidification component for the user to inhale through the nasal cannula connected to the oxygen outlet; and / or, when humidifying the room, the humidification component can produce atomized liquid to humidify the room.

[0013] Because the humidifier assembly is detachably installed on the side of the housing, it can be removed from the housing when adding liquid, making it convenient to add liquid to the control terminal. Compared to the existing technology that requires placing the water cup on top of the control terminal for liquid addition, this reduces the difficulty of adding liquid to the control terminal, improving the efficiency for users. Furthermore, it avoids liquid spillage onto the housing, requiring user cleaning and ensuring the cleanliness of the control terminal. It also prevents liquid from entering the control terminal and damaging the internal circuitry, thus reducing the failure rate, improving safety, and extending the lifespan of the control terminal.

[0014] Optionally, the housing has a receiving cavity with a downward-facing opening, and the control terminal further includes a pulse oximeter that can be received in the receiving cavity via the opening, and a winding structure for winding up the wiring harness of the pulse oximeter.

[0015] By adopting the above technical solution, since the control terminal also includes a pulse oximeter, the control terminal in this application integrates the function of detecting blood oxygen for the user, thereby increasing the flexibility of the control terminal; since the pulse oximeter can be stored in the storage cavity through the cavity opening, the pulse oximeter can be stored, thereby making the external outline of the control terminal more regular, thereby improving the user's touch experience.

[0016] Since the pulse oximeter can be stored in the storage cavity through the opening, the storage cavity allows for easy access to the pulse oximeter. However, when placing the pulse oximeter in the storage cavity, the wiring harness may interfere with the pulse oximeter. This application addresses this by incorporating a winding structure to automatically wind up the pulse oximeter's wiring harness, preventing the pulse oximeter from being unable to be placed in the storage cavity due to the presence of the wiring harness. This reduces the difficulty of placing the pulse oximeter in the storage cavity. Furthermore, the winding force of the winding structure on the wiring harness can apply an upward pulling force to the pulse oximeter, ensuring its stability when placed in the storage cavity.

[0017] Because the opening of the storage chamber faces downwards, it prevents dust or other objects from falling into the storage chamber. This ensures the cleanliness of both the storage chamber and the pulse oximeter, thereby guaranteeing the accuracy of the pulse oximeter's measurements. On the other hand, it also prevents other objects from entering the storage chamber and affecting the placement of the pulse oximeter, thus ensuring the convenience of placing the pulse oximeter in the storage chamber.

[0018] Optionally, the wet mist assembly has a first liquid chamber, a second liquid chamber, an oxygen inlet communicating with the first liquid chamber, and an oxygen outlet communicating with the first liquid chamber. The oxygen inlet is connected to the regulating valve through a flow control valve. The wet mist assembly includes an atomizing structure for atomizing the liquid contained in the second liquid chamber and spraying the atomized liquid out.

[0019] By adopting the above technical solution, when the diffusion oxygen generator with the control terminal of this application is working, part of the oxygen produced by the oxygen generator flows directly into the diffusion gas box after passing through the regulating valve, so that the oxygen in the diffusion gas box is released into the indoor environment by diffusion. The remaining oxygen after passing through the regulating valve enters the first liquid chamber through the flow control valve and the oxygen inlet, so that the liquid entering the first liquid chamber comes into contact with the liquid contained in the first liquid chamber, thereby humidifying the oxygen. The humidified oxygen is discharged from the first liquid chamber through the oxygen outlet for the user to inhale through the nasal cannula connected to the oxygen outlet. When humidifying the room, the atomizing structure atomizes the liquid in the second liquid chamber, so that the atomized liquid is sprayed out of the second liquid chamber to achieve humidification of the room.

[0020] Because the humidifier assembly has a first liquid chamber and a second liquid chamber, it integrates the humidifier cup used to increase indoor humidity and the humidifier cup used to humidify oxygen in the prior art. On the one hand, it allows the first liquid chamber and the second liquid chamber to be located in the same position in the housing, thereby reducing the size of the control terminal and facilitating the miniaturization of the control terminal. On the other hand, it reduces the number of parts required to assemble the control terminal, thereby improving the assembly efficiency and reducing the assembly cost. Furthermore, compared with the prior art where the humidifier cup and the humidifier cup are set separately, it avoids the need to separately mold and produce the humidifier cup and the humidifier cup, thus reducing the production cost of the control terminal.

[0021] Optionally, the side of the housing has a mounting position, the wet mist assembly is detachably mounted at the mounting position, the wet mist assembly also includes a cup body and a cup lid covering the cup body, the first liquid chamber and the second liquid chamber are located inside the cup body, and the atomizing structure is located on the cup lid.

[0022] By adopting the above technical solution, since the humidifier assembly is detachably installed at the mounting position, and the humidifier assembly also includes a cup body, with the first and second liquid chambers located inside the cup body, the humidifier assembly can be removed from the housing when adding liquid to the first and second liquid chambers. This further facilitates the addition of liquid to the first and second liquid chambers, thereby improving the user experience. Furthermore, compared to the existing technology where the humidifier cup and humidification cup are fixedly connected to the control terminal, this avoids the need to manually add liquid to the humidifier cup or humidification cup. In case of liquid spillage onto the control terminal, which could potentially cause a short circuit and damage, this design ensures the lifespan of the control terminal and avoids the need for wiping the terminal after liquid spillage, thus reducing user workload and ensuring the cleanliness of the control terminal. Furthermore, when servicing the wet mist component, it can be removed from the housing, avoiding the need to disassemble the entire control terminal, thereby reducing the difficulty of servicing the wet mist component and achieving a convenient maintenance effect.

[0023] Furthermore, since the atomizing structure is located in the cup lid, when inspecting the atomizing structure, only the cup lid needs to be disassembled, which reduces the difficulty of inspecting the atomizing structure and makes it easier to inspect it.

[0024] Optionally, the housing has a front side and a rear side opposite to the front side. The front side of the housing has a display and operation area. A clearance area is provided on the side of the cup body corresponding to the rear side of the housing. The clearance area is recessed into the cup body to form a hand-holding space that can accommodate fingers, and the hand-holding space is exposed to the outer contour of the housing.

[0025] By adopting the above technical solution, when removing the humidifier from the housing, the user can insert their fingers into the hand-holding space and then use their hand to apply a pulling force away from the mounting position to remove the humidifier from the housing, thus achieving the effect of making it easy to remove the humidifier from the housing.

[0026] Optionally, the cup body has an exposed surface that is exposed to the outer contour of the housing and a hidden surface that can be hidden inside the housing. A decorative panel is provided on the exterior of the exposed surface, and the decorative panel has a recessed groove corresponding to the avoidance area.

[0027] By adopting the above technical solution, since the decorative panel is located on the exposed surface, it can be used to cover and decorate the cup body, thereby improving the appearance quality of the control terminal and thus improving the user experience. Since the decorative panel has a recessed groove corresponding to the avoidance area, when the user removes the misting component from the housing, he / she can insert his / her fingers into the recessed groove and use the force applied by his / her fingers to the groove wall to remove the misting component from the housing.

[0028] Optionally, the clearance area is provided with a mounting part, and the decorative panel is provided with a connecting part, which is connected to the mounting part by fasteners.

[0029] By adopting the above technical solution, since the avoidance area is provided with an installation part and the decorative panel is provided with a connecting part, and the connecting part is connected to the installation part by fasteners, the installation difficulty of the decorative panel is reduced on the one hand, so as to facilitate the installation of the decorative panel, and on the other hand, the connection stability between the decorative panel and the cup body is increased.

[0030] Optionally, the front side of the housing has a limiting notch, the decorative panel has a limiting rib extending into the limiting notch, the side of the limiting rib is provided with a mating part, and the cup body is provided with a plug-in part that engages with the mating part.

[0031] By adopting the above technical solution, since the decorative panel has a limiting rib that extends into the limiting notch, on the one hand, the limiting rib and the limiting notch can be used to position the wet fog component, so as to facilitate the installation of the wet fog component. On the other hand, when installing or removing the wet fog component, the user's fingers can press the limiting rib and the groove wall of the recessed groove respectively, so as to use the user's hands to grasp the wet fog component, thereby further reducing the difficulty of installing or removing the wet fog component.

[0032] Optionally, the second liquid-containing cavity is located in front of the first liquid-containing cavity, the decorative panel is provided with a first viewing window for observing the liquid level in the first liquid-containing cavity, and the housing is provided with a second viewing window for observing the liquid level in the second liquid-containing cavity.

[0033] By adopting the above technical solution, since the control terminal is generally installed on the indoor wall, and the second liquid chamber in this application is located in front of the first liquid chamber, the distance between the atomizing structure and the wall is increased. This avoids the situation where the atomized liquid easily adheres to the wall when the control terminal humidifies the room, causing the wall to become damp. This avoids the situation where bacteria easily grow and the decorative layer peels off due to long-term dampness of the wall, thereby improving the user experience.

[0034] Furthermore, since the decorative panel is provided with a first viewing window and the housing is provided with a second viewing window, the remaining amount of liquid in the first liquid chamber can be observed through the first viewing window and the remaining amount of liquid in the second liquid chamber can be observed through the second viewing window, so that the user can add liquid to the first liquid chamber and the second liquid chamber in a timely manner, thereby further improving the user experience.

[0035] Optionally, the mounting position is provided with a light, which is located inside the cup body.

[0036] By adopting the above technical solution, since the installation position is equipped with a light and the light is located inside the cup body, the cup body can be illuminated by the light, which makes it easier for the user to observe the remaining amount of liquid in the first liquid chamber and the second liquid chamber, thereby further improving the user experience.

[0037] Optionally, one of the mounting position and the cup body is provided with a positioning hole, and the other of the two is provided with a positioning post extending into the positioning hole.

[0038] By adopting the above technical solution, after the wet fog component is installed in the mounting position, the positioning post extends into the positioning hole. The positioning post and the positioning hole are used to limit and position the wet fog component, thereby increasing the connection stability between the wet fog component and the mounting position and further improving the user experience.

[0039] Optionally, the lower part of the cup body is provided with a water level probe that extends into the second liquid cavity, and the mounting position is provided with a conductive part that can be electrically connected to the water level probe.

[0040] By adopting the above technical solution, since a water level probe is provided at the bottom of the cup body and extends into the second liquid chamber, the water level probe can be used to detect the liquid level in the second liquid chamber. When the liquid level in the second liquid chamber is lower than the water level probe, the water level probe can send a signal to the control module of the control terminal, so that the control module of the control terminal can issue an alarm or terminate the operation of the atomizing structure, thereby avoiding the situation where the atomizing structure is not working properly, and further improving the user experience.

[0041] Optionally, the atomizing structure includes a water-absorbing element passing through the cup lid and an atomizing element disposed on the cup lid. One bottom end of the water-absorbing element extends into the second liquid-containing cavity, and one top end of the water-absorbing element abuts against the bottom of the atomizing element, so that the liquid contained in the second liquid-containing cavity moves to the bottom of the atomizing element under the action of the water-absorbing element. The cup lid is provided with a mist outlet corresponding to the atomizing element.

[0042] By adopting the above technical solution, when the control terminal humidifies the room, the water absorption component delivers the liquid in the second liquid chamber to the bottom of the atomizing component, so that the atomizing component atomizes the liquid. The atomized liquid is then sprayed out through the mist outlet to increase the indoor humidity.

[0043] In this application, the liquid contained in the second liquid chamber is transported to the bottom of the atomizing element through the water-absorbing component, thereby positioning the atomizing element above the second liquid chamber. Compared to the prior art where the atomizing element is placed in the liquid, the water-absorbing component can filter the liquid, reducing the atomizing element's water quality requirements and thus lowering the user's operating costs. It also reduces damage to the atomizing element caused by water quality issues, thereby extending the atomizing element's service life and reducing the failure rate of the wet mist assembly.

[0044] In addition, since the atomizing component is located in the cup lid, compared with the existing technology that places the atomizing component inside the humidifying cup, the difficulty of repairing and replacing the atomizing component is reduced, thereby achieving the effect of facilitating the maintenance of the humidification assembly.

[0045] Optionally, the diffused gas box has multiple air outlets, and the housing is provided with annular ribs surrounding the multiple air outlets. The housing, the diffused gas box, and the annular ribs together form a diffused cavity. The housing is provided with multiple diffused holes communicating with the diffused cavity, and the number of diffused holes is greater than the number of air outlets.

[0046] By adopting the above technical solution, after oxygen enters the diffusion box, the oxygen diffuses in the diffusion box and finally enters the diffusion chamber through the outlet. The oxygen in the diffusion chamber diffuses in the diffusion chamber and is finally released into the indoor environment through the diffusion hole in a diffuse manner.

[0047] Because oxygen undergoes multiple diffusion processes when released into the room through diffusion, the kinetic energy of the oxygen as it exits through the diffusion holes is reduced, thereby reducing the noise generated when the diffusion box releases oxygen and improving the user experience.

[0048] Furthermore, since the number of diffusion holes is greater than the number of air outlet holes, oxygen in the diffusion chamber is released through multiple diffusion holes, thereby improving the diffusion effect of the diffusion gas box on oxygen and further enhancing the user experience.

[0049] Optionally, the diffused gas box has an internal gas chamber filled with noise-reducing cotton and multiple partitions for dividing the gas chamber into multiple buffer chambers. Each partition forms a communication port with the cavity wall of the gas chamber, and adjacent communication ports are staggered.

[0050] By adopting the above technical solution, since the gas chamber is filled with noise-reducing cotton, the oxygen entering the gas chamber moves inside the noise-reducing cotton, thereby reducing the noise generated by the contact friction between the oxygen flow and the cavity wall of the gas chamber, and further improving the noise reduction effect of the diffused gas box.

[0051] Furthermore, since each partition forms a connection with the cavity wall of the gas chamber, and adjacent connections are staggered, this increases the movement path of oxygen in the gas chamber, thereby increasing the kinetic energy consumption of oxygen flowing in the gas chamber. This further reduces the kinetic energy of oxygen when it is discharged through the diffusion holes, thus further improving the noise reduction effect of the diffusion gas box. On the other hand, it increases the number of times oxygen diffuses in the gas chamber, further reducing the kinetic energy of oxygen, thus further improving the noise reduction effect of the diffusion gas box.

[0052] Optionally, the diffused gas box has an air inlet communicating with the gas chamber, an air inlet nozzle extends from the air inlet, the air inlet nozzle is provided with an air inlet pipe communicating with the regulating valve, and a flow regulator is provided in the air inlet pipe.

[0053] By adopting the above technical solution, since an air inlet is extended at the air inlet, it is easy to connect the air inlet pipe to the air inlet, thereby reducing the assembly difficulty of the control terminal; since a flow regulator is installed in the air inlet pipe, the flow rate and pressure of oxygen in the input gas chamber can be adjusted by the flow regulator, thereby reducing the pressure of oxygen entering the gas chamber, and further improving the noise reduction effect on the diffused gas box.

[0054] Optionally, the housing has internal ribs that form a cavity between the ribs and the housing. The housing is provided with a temperature and humidity detection hole that communicates with the cavity. The control terminal also includes a temperature and humidity sensor located in the cavity.

[0055] By adopting the above technical solution, since the temperature and humidity sensor is located in the accommodating cavity, and the accommodating cavity is formed by the surrounding ribs and the shell, the temperature and humidity sensor is isolated from other components inside the shell, so as to avoid the influence of the heat released by other components inside the shell on the temperature and humidity sensor's indoor temperature detection, thereby improving the accuracy of the temperature and humidity sensor's indoor temperature detection.

[0056] Optionally, the housing has a front side and a rear side opposite to the front side. The front side of the housing has a display and operation area, and the rear side of the housing is provided with a pipeline groove. The groove wall of the pipeline groove is provided with a terminal air inlet and a terminal hole.

[0057] By adopting the above technical solution, since a pipeline groove is provided on the rear side of the housing, and the groove wall is provided with a terminal air inlet and a terminal hole, the pipeline connecting the oxygen generator and the control terminal can be placed in the pipeline groove so that the rear side of the housing can completely abut against the wall or other mounting surface, thereby ensuring the stability of the control terminal.

[0058] Optionally, the control terminal further includes an oxygen concentration sensor, which is disposed in the mounting cavity, and the housing is provided with an oxygen concentration detection hole communicating with the mounting cavity corresponding to the oxygen concentration sensor.

[0059] By adopting the above technical solution, since the control terminal also includes an oxygen concentration sensor, it is possible to detect the indoor oxygen concentration using the control terminal, thereby increasing the flexibility of the control terminal. At the same time, the oxygen concentration sensor can also send an oxygen concentration signal to the control module of the control terminal, so that the control module can adjust the oxygen generator and regulating valve according to the oxygen concentration signal, ultimately keeping the indoor oxygen concentration within an optimal range, thereby improving the user experience.

[0060] Optionally, the control terminal may further include a wireless signal receiving sensor disposed in the mounting cavity.

[0061] By adopting the above technical solution, since the control terminal also includes a wireless signal receiving sensor, it can send signals to the control terminal wirelessly, thereby facilitating user control of the control terminal. This increases the flexibility of the control terminal and improves the user experience.

[0062] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0063] 1. The control terminal in this application includes a housing, a regulating valve, a diffused gas box, and a humidifier assembly. The housing has an internal mounting cavity. The regulating valve is connected to the air inlet pipe and located within the mounting cavity. The diffused gas box is located within the mounting cavity and is connected to the regulating valve. Gas entering the diffused gas box through the regulating valve can be released to the outside of the housing through the diffused gas box. The humidifier assembly is detachably installed on the side of the housing and is used to humidify the output gas or generate atomized liquid. This reduces the difficulty of adding liquid to the control terminal, thereby improving the efficiency of liquid addition for the user. Furthermore, it avoids the situation where liquid spills onto the housing during liquid addition, requiring the user to clean the housing, thus ensuring the cleanliness of the control terminal. It also prevents liquid from entering the control terminal's interior and damaging the internal circuitry, thereby reducing the failure rate of the control terminal, improving its safety, and ensuring its service life.

[0064] 2. The housing in this application has a storage cavity with a downward-facing opening. The control terminal also includes a pulse oximeter that can be stored in the storage cavity through the opening and a winding structure for winding the wiring harness of the pulse oximeter. On the one hand, this enables the control terminal to integrate the function of pulse oximeter detection, thereby increasing the flexibility of the control terminal. On the other hand, it makes the external contour of the control terminal more regular, thereby improving the user's touch experience. Furthermore, it also facilitates the placement of the pulse oximeter in the storage cavity.

[0065] 3. The housing in this application has a mounting position on its side, where the humidifying component is detachably mounted. The humidifying component also includes a cup body and a lid covering the cup body. The first and second liquid chambers are located inside the cup body, and the atomizing structure is located on the lid. This allows the humidifying component to be removed from the housing when adding liquid to the first and second liquid chambers, further facilitating the addition of liquid and improving the user experience. Furthermore, compared to the prior art where the humidifying cup and humidifying container are fixedly connected to the control terminal, this avoids the need for... When liquid is added to the wet cup or humidification cup, spillage onto the control terminal could potentially cause a short circuit and damage. This design ensures the lifespan of the control terminal and avoids the need to wipe it after spillage, reducing user workload and ensuring the cleanliness of the control terminal. Furthermore, when servicing the wet mist component, it can be removed from the housing, avoiding the need to disassemble the entire control terminal. This simplifies the maintenance process and makes the wet mist component easier to repair. Attached Figure Description

[0100] Reference Figures 1 to 26 A control terminal for a diffusion oxygen generator is disclosed, comprising a housing 1, a regulating valve 2, a diffusion gas box 3, and a wet mist component 4. The housing 1 has an internal mounting cavity 11. The regulating valve 2 is connected to the air inlet pipe and located in the mounting cavity 11. The diffusion gas box 3 is located in the mounting cavity 11 and is connected to the regulating valve 2. The gas entering the diffusion gas box 3 through the regulating valve 2 can be released to the outside of the housing 1 through the diffusion gas box 3. The wet mist component 4 is detachably installed on the side of the housing 1 and is used to humidify the output gas or generate atomized liquid.

[0101] It is understandable that the air inlet of regulating valve 2 is connected to the air inlet pipe connected to the oxygen generator so that the oxygen produced by the oxygen generator can enter regulating valve 2.

[0102] It should be noted that the above-mentioned "humidifying mist component 4 for output gas humidification or generating atomized liquid" means that the humidifying mist component 4 can humidify the oxygen supplied to the user or can produce atomized liquid so as to humidify the room.

[0103] When the diffusion oxygen generator with the control terminal described in this application is working, part of the oxygen produced by the oxygen generator flows directly into the diffusion gas box 3 after passing through the regulating valve 2, so that the oxygen entering the diffusion gas box 3 is released into the indoor environment by diffusion. The remaining oxygen after passing through the regulating valve 2 flows into the humidification mist assembly 4, so that the humidification mist assembly 4 humidifies the oxygen. The humidified oxygen is discharged from the humidification mist assembly 4 for the user to inhale through the nasal cannula connected to the oxygen outlet 418; and / or, when humidifying the room, the humidification mist assembly 4 can produce atomized liquid to humidify the room.

[0104] Since the misting component 4 is detachably installed on the side of the housing 1, it can be removed from the housing 1 when adding liquid, thus facilitating the addition of liquid to the control terminal. Compared with the existing technology that requires placing the water cup on top of the control terminal for liquid addition, this reduces the difficulty of adding liquid to the control terminal, improving the efficiency of liquid addition for users. Furthermore, it avoids the situation where liquid spills onto the housing 1 during liquid addition, requiring users to clean the housing 1, ensuring the cleanliness of the control terminal. It also prevents liquid from entering the control terminal and damaging the internal circuitry, thereby reducing the failure rate, improving the safety of the control terminal, and ensuring its service life.

[0105] This application does not specifically limit the structure of the regulating valve 2; preferably, refer to... Figure 5 The regulating valve 2 is a solenoid valve to ensure the efficiency of connecting or disconnecting the control terminal and the oxygen generator. In other embodiments, the regulating valve 2 can also be a pneumatic valve or other structures capable of controlling the connection or disconnection between the control terminal and the oxygen generator.

[0106] In a preferred embodiment, refer to Figure 3 and Figure 5 The housing 1 has a receiving cavity 12 with a downward-facing opening. The control terminal also includes a pulse oximeter 6 that can be received in the receiving cavity 12 through the opening of the receiving cavity 12, and a winding structure 61 for winding the wire harness of the pulse oximeter 6.

[0107] Since the control terminal also includes a pulse oximeter 6, the control terminal in this application integrates the function of detecting blood oxygen for the user, thereby increasing the flexibility of the control terminal; since the pulse oximeter 6 can be stored in the storage cavity 12 through the cavity opening, the storage of the pulse oximeter 6 is realized, thereby making the external outline of the control terminal more regular, thereby improving the user's touch experience.

[0108] Since the pulse oximeter 6 can be stored in the storage cavity 12 through the cavity opening, the pulse oximeter 6 can be stored in the storage cavity 12 in a way that allows it to be put in and taken out. However, when the pulse oximeter 6 is placed in the storage cavity 12, the wiring harness of the pulse oximeter 6 may interfere with the pulse oximeter 6. In this application, by setting up a winding structure 61, the wiring harness of the pulse oximeter 6 can be automatically wound up, so as to avoid the situation where the pulse oximeter 6 cannot be put into the storage cavity 12 due to the presence of the wiring harness. This reduces the difficulty of placing the pulse oximeter 6 in the storage cavity 12. At the same time, the winding force of the winding structure 61 on the wiring harness can also be used to apply an upward pulling force to the pulse oximeter 6 to ensure the stability of the pulse oximeter 6 placed in the storage cavity 12.

[0109] Because the opening of the storage cavity 12 faces downwards, it prevents dust or other objects from falling into the storage cavity 12. This ensures the cleanliness of both the storage cavity 12 and the pulse oximeter 6, thereby guaranteeing the measurement accuracy of the pulse oximeter 6. On the other hand, it prevents other objects from entering the storage cavity 12 from affecting the placement of the pulse oximeter 6 in the storage cavity 12, thus ensuring the convenience of placing the pulse oximeter 6 in the storage cavity 12.

[0110] Preferably, the pulse oximeter 6 is a finger clip pulse oximeter to improve the accuracy of blood oxygen detection and the efficiency of blood oxygen measurement.

[0111] This application does not specify the location of the storage cavity 12; preferably, refer to... Figure 3 and Figure 5 The receiving cavity 12 is a cavity formed by the rib structure located inside the mounting cavity 11. In other words, the receiving cavity 12 is located inside the mounting cavity 11 to make full use of the internal space of the mounting cavity 11, thereby improving the space utilization rate of the mounting cavity 11 and facilitating the miniaturization design of the control terminal. In other embodiments, the receiving cavity 12 may also be located on the side of the housing 1.

[0112] This application does not specifically limit the winding structure 61. Preferably, the winding structure 61 includes a winding box disposed inside the mounting cavity 11 and a coil spring disposed inside the winding box. The outer end of the coil spring is connected to the wiring harness of the pulse oximeter 6. When the pulse oximeter 6 is removed from the storage cavity 12, the pulse oximeter 6 pulls the wiring harness, and the wiring harness applies tension to the coil spring, causing the coil spring to undergo elastic deformation. When the pulse oximeter 6 is placed in the storage cavity 12, the coil spring gradually restores its deformation, so that the coil spring applies a winding force to the wiring harness of the pulse oximeter 6, ultimately causing the wiring harness of the pulse oximeter 6 to wrap around the outside of the coil spring, thereby achieving the winding of the wiring harness of the pulse oximeter 6. In other embodiments, the winding structure 61 may also refer to the structure of a retractable data cable.

[0113] In a preferred embodiment, the wet mist assembly 4 has a first liquid chamber 411, a second liquid chamber 419, an oxygen inlet 417 communicating with the first liquid chamber 411, and an oxygen outlet 418 communicating with the first liquid chamber 411. The oxygen inlet 417 is connected to the regulating valve 2 through a flow control valve 5. The wet mist assembly 4 includes an atomizing structure for atomizing the liquid contained in the second liquid chamber 419 and causing the atomized liquid to be sprayed out.

[0114] It is understandable that a three-way connector is provided between the regulating valve 2, the flow control valve 5, and the diffused gas box 3. The three ports of the three-way connector are respectively connected to the outlet of the regulating valve 2, the inlet of the diffused gas box 3, and the inlet of the flow control valve 5 through pipelines, so as to realize that the diffused gas box 3 and the flow control valve 5 are simultaneously connected to the regulating valve 2; the flow control valve 5 is connected to the oxygen inlet 417 through a pipeline; an oxygen outlet nozzle is extended at the oxygen outlet 418 to facilitate the connection of the nasal cannula to the oxygen outlet 418.

[0115] When the diffusion oxygen generator with the control terminal described in this application is working, part of the oxygen produced by the oxygen generator flows directly into the diffusion gas box 3 after passing through the regulating valve 2, so that the oxygen in the diffusion gas box 3 is released into the indoor environment through diffusion. The remaining oxygen after passing through the regulating valve 2 enters the first liquid chamber 411 through the flow control valve 5 and the oxygen inlet 417, so that the liquid in the first liquid chamber 411 comes into contact with the liquid in the first liquid chamber 411, thereby humidifying the oxygen. The humidified oxygen is discharged from the first liquid chamber 411 through the oxygen outlet 418 for the user to inhale through the nasal cannula connected to the oxygen outlet 418. When humidifying the room, the atomizing structure atomizes the liquid in the second liquid chamber 419, so that the atomized liquid is sprayed out of the second liquid chamber 419 to achieve humidification of the room.

[0116] Since the humidification component 4 has a first liquid chamber 411 and a second liquid chamber 419, it integrates the humidification cup used to increase indoor humidity and the humidification cup used to humidify oxygen in the prior art. On the one hand, it allows the first liquid chamber 411 and the second liquid chamber 419 to be located in the same position in the housing 1, thereby reducing the size of the control terminal and achieving the effect of miniaturizing the control terminal. On the other hand, it reduces the number of parts required to assemble the control terminal, thereby improving the assembly efficiency and reducing the assembly cost of the control terminal. Furthermore, compared with the prior art's separate humidification cup and humidification cup, it avoids the need to separately mold and produce the humidification cup and humidification cup, thereby reducing the production cost of the control terminal.

[0117] Furthermore, since the wet mist component 4 in this application integrates the first liquid chamber 411 and the second liquid chamber 419, when adding liquid to one of the first liquid chamber 411 and the second liquid chamber 419, excess liquid can be added to the other one with a small movement, so as to a certain extent, it is convenient to add liquid to the first liquid chamber 411 and the second liquid chamber 419, thereby improving the convenience of adding liquid to the control terminal.

[0118] In addition, in this application, by using the flow control valve 5 to connect the regulating valve 2 to the oxygen inlet 417, the flow rate of oxygen entering the first liquid chamber 411 can be adjusted by adjusting the flow control valve 5, thereby allowing the user to select whether to humidify the oxygen as needed.

[0119] This application does not specifically limit the structure of the flow control valve 5; preferably, refer to... Figure 5 The flow control valve 5 is electronic, allowing the user to adjust the flow rate of oxygen entering the first liquid chamber 411 by operating the display and operation area of ​​the control terminal, thus achieving precise oxygen flow rate adjustment. In other embodiments, the flow control valve 5 can also be manual, requiring the user to manually adjust the flow control valve 5, thereby reducing the production cost of the control terminal.

[0120] This application does not specifically limit the arrangement of the first liquid chamber 411 and the second liquid chamber 419. Preferably, refer to Figure 4 The housing 1 has a mounting position 13 on its side. The wet mist assembly 4 is detachably mounted on the mounting position 13. The wet mist assembly 4 also includes a cup body 41 and a cup lid 42 covering the cup body 41. The first liquid chamber 411 and the second liquid chamber 419 are located inside the cup body 41, and the atomizing structure is located on the cup lid 42.

[0121] It is understood that the first liquid-containing cavity 411 and the second liquid-containing cavity 419 are formed by the internal space of the cup body 41, and the first liquid-containing cavity 411 and the second liquid-containing cavity 419 are both integrated into the same cup body 41.

[0122] Since the humidifier assembly 4 is detachably installed at the mounting position 13, and the humidifier assembly 4 also includes a cup body 41, with the first liquid chamber 411 and the second liquid chamber 419 located inside the cup body 41, the humidifier assembly 4 can be removed from the housing 1 when adding liquid to the first liquid chamber 411 and the second liquid chamber 419. This further facilitates the addition of liquid to the first liquid chamber 411 and the second liquid chamber 419, thereby improving the user experience. Furthermore, compared to the existing technology where the humidifier cup and the humidification cup are fixedly connected to the control terminal, this avoids the inconvenience of adding liquid to the humidifier cup or the humidification cup. When liquid is added to the cup, spillage onto the control terminal could potentially cause a short circuit and damage. This design ensures the lifespan of the control terminal and avoids the need to wipe it after spillage, reducing user workload and ensuring the cleanliness of the control terminal. Furthermore, when inspecting the wet mist component 4, it can be removed from the housing 1, avoiding the need to disassemble the entire control terminal. This simplifies the inspection and maintenance of the wet mist component 4, making it easier to perform maintenance.

[0123] Furthermore, since the atomizing structure is located in the cup lid 42, when inspecting the atomizing structure, only the cup lid 42 needs to be disassembled, thereby reducing the difficulty of inspecting the atomizing structure and achieving the effect of facilitating the inspection of the atomizing structure.

[0124] The better one is to refer to Figure 10 The top of the cup body 41 is provided with a first liquid inlet 416 communicating with the first liquid chamber 411 and a second liquid inlet 481 communicating with the second liquid chamber 419, so as to facilitate the addition of liquid to the first liquid chamber 411 and the second liquid chamber 419.

[0125] This application does not specifically limit the formation of the mounting position 13; preferably, refer to Figure 4 The side of the housing 1 is recessed towards the interior to form a mounting position 13, and the opening of the mounting position 13 faces the side of the housing 1 to facilitate the placement and removal of the wet mist assembly 4. In other embodiments, the top of one end of the housing 1 is recessed downward to form the mounting position 13, and the opening of the mounting position 13 faces upward towards the housing 1.

[0126] Furthermore, refer to Figure 8 and Figure 11The housing 1 has a front side and a rear side opposite to the front side. The front side of the housing 1 has a display and operation area. The side of the cup body 41 is provided with a relief area 482 corresponding to the rear side of the housing 1. The relief area 482 is recessed into the inside of the cup body 41 to form a hand-holding space that can accommodate fingers, and the hand-holding space is exposed to the outer contour of the housing 1.

[0127] When removing the humidifier assembly 4 from the housing 1, the user can insert their fingers into the hand-holding space and then use their hand to apply a pulling force away from the mounting position 13 to the cup body 41 to remove the humidifier assembly 4 from the housing 1, thereby facilitating the removal of the humidifier assembly 4 from the housing 1.

[0128] Furthermore, refer to Figure 6 and Figure 7 The cup body 41 has an exposed surface that is exposed to the outer contour of the shell 1 and a hidden surface that can be hidden inside the shell 1. A decorative panel 43 is provided on the exterior of the exposed surface, and a recessed groove 431 is provided on the decorative panel 43 corresponding to the avoidance area 482.

[0129] Understandably, the decorative panel 43 is provided with a hole for the oxygen outlet to extend out, so that the oxygen outlet can extend out of the decorative panel 43, thereby facilitating the connection between the nasal cannula and the oxygen outlet.

[0130] Since the decorative panel 43 is located on the exposed surface, it can be used to cover and decorate the cup body 41, thereby improving the appearance quality of the control terminal and thus improving the user experience. Since the decorative panel 43 is provided with a recessed groove 431 corresponding to the avoidance area 482, when the user removes the misting component 4 from the housing 1, he / she can insert his / her fingers into the recessed groove 431 and use the force applied by his / her fingers to the groove wall of the recessed groove 431 to remove the misting component 4 from the housing 1.

[0131] The better one is to refer to Figure 17 A blocking rib 432 is provided on the groove wall of the recessed groove 431 near the front side of the housing 1, so that when the user inserts his / her fingers into the recessed groove 431, the blocking rib 432 can block the user's hand to avoid the user's hand slipping relative to the groove wall of the recessed groove 431, thereby making it easier for the user to remove the wet mist component 4 from the housing 1.

[0132] This application does not specify the connection method between the decorative panel 43 and the cup body 41. Preferably, refer to... Figure 8 , Figure 11 and Figure 18 The clearance area 482 is provided with an installation part 483, and the decorative panel 43 is provided with a connecting part 433. The connecting part 433 is connected to the installation part 483 by fasteners.

[0133] Since the clearance area 482 is provided with an installation part 483 and the decorative panel 43 is provided with a connecting part 433, and the connecting part 433 is connected to the installation part 483 by fasteners, the installation difficulty of the decorative panel 43 is reduced on the one hand, so as to facilitate the installation of the decorative panel 43, and the connection stability between the decorative panel 43 and the cup body 41 is increased on the other hand.

[0134] This application does not specifically limit the structure of the mounting part 483 and the connecting part 433. Preferably, the mounting part 483 is a plate-like structure provided on the cup body 41, and the connecting part 433 is a column-like structure provided on the decorative panel 43. In other embodiments, both the mounting part 483 and the connecting part 433 can also be plate-like structures.

[0135] This application does not specifically limit the structure of the fastener. Preferably, the fastener is a screw that can be threaded through the connecting part 433 and the mounting part 483 to increase the connection stability between the decorative plate 43 and the cup body 41. In other embodiments, the fastener may also be a snap-fit ​​structure that can fix the connecting part 433 and the fixing plate together.

[0136] Furthermore, refer to Figure 1 and Figure 4 The front side of the shell 1 has a limiting notch 14, the decorative panel 43 has a limiting rib 434 extending into the limiting notch 14, the side of the limiting rib 434 is provided with a mating part 435, and the cup body 41 is provided with a plug-in part 484 that is plugged into the mating part 435.

[0137] Understandably, the limiting notch 14 is located at the end of the housing 1 so that the limiting rib 434 can enter the limiting notch 14 in a direction close to the housing 1.

[0138] Since the decorative panel 43 has a limiting rib 434 that extends into the limiting notch 14, on the one hand, the limiting rib 434 and the limiting notch 14 can be used to position the wet fog component 4, so as to facilitate the installation of the wet fog component 4. On the other hand, when assembling and disassembling the wet fog component 4, the user's fingers can press the limiting rib 434 and the groove wall of the recessed groove 431 respectively, so as to use the user's hands to grasp the wet fog component 4, thereby further reducing the difficulty of assembling and disassembling the wet fog component 4.

[0139] Furthermore, since the limiting rib 434 has a mating part 435 on its side and the cup body 41 has a plug-in part 484 that engages with the mating part 435, the decorative panel 43 can be positioned by the engagement of the mating part 435 and the plug-in part 484, so as to facilitate the fixing of the decorative panel 43 with fasteners. On the other hand, the engagement of the mating part 435 and the plug-in part 484 can limit the position of the decorative panel 43, thereby further increasing the connection stability between the decorative panel 43 and the cup body 41.

[0140] This application does not specifically limit the structure of the mating part 435 and the insertion part 484. Preferably, the insertion part 484 is a block-shaped structure provided on the side of the cup body 41, and the mating part 435 is a rib structure provided on the limiting rib 434. A space is formed between the rib structure and the limiting rib 434 for the insertion part 484 to be inserted, thereby realizing the insertion and mating of the insertion part 484 and the mating part 435. In other embodiments, the structures of the mating part 435 and the insertion part 484 can be interchanged.

[0141] This application does not specifically limit the relative positions of the first liquid chamber 411 and the second liquid chamber 419. Preferably, refer to Figure 1 The second liquid chamber 419 is located in front of the first liquid chamber 411. The decorative panel 43 is provided with a first viewing window 436 that can observe the liquid level in the first liquid chamber 411, and the housing 1 is provided with a second viewing window 15 that can observe the liquid level in the second liquid chamber 419.

[0142] It is understandable that the cup body 41 is made of transparent plastic material so that the liquid level in the first liquid chamber 411 can be seen through the first viewing window 436 and the liquid level in the second liquid chamber 419 can be seen through the second viewing window 15.

[0143] Since the control terminal is generally installed on the indoor wall, and the second liquid chamber 419 in this application is located in front of the first liquid chamber 411, the distance between the atomizing structure and the wall is increased. This avoids the situation where the atomized liquid easily adheres to the wall when the control terminal humidifies the room, causing the wall to become damp. This avoids the situation where bacteria easily grow and the decorative layer peels off due to long-term dampness of the wall, thereby improving the user experience.

[0144] Furthermore, since the decorative panel 43 is provided with a first viewing window 436 and the housing 1 is provided with a second viewing window 15, the remaining amount of liquid in the first liquid chamber 411 can be observed through the first viewing window 436 and the remaining amount of liquid in the second liquid chamber 419 can be observed through the second viewing window 15, so that the user can add liquid to the first liquid chamber 411 and the second liquid chamber 419 in a timely manner, thereby further improving the user experience.

[0145] In other implementation examples, the first liquid chamber 411 may be located in front of the second liquid chamber 419 or at the bottom of the second liquid chamber 419.

[0146] Furthermore, refer to Figure 26 The mounting position 13 is equipped with a light 131, which is located inside the cup body 41. The light 131 can illuminate the cup body 41, making it easier for the user to observe the remaining amount of liquid in the first liquid chamber 411 and the second liquid chamber 419, thereby further improving the user experience.

[0147] In a preferred embodiment, refer to Figure 9 and Figure 26 One of the mounting position 13 and the cup body 41 is provided with a positioning hole 132, and the other of them is provided with a positioning post 485 that extends into the positioning hole 132.

[0148] After the humidifier assembly 4 is installed in the mounting position 13, the positioning post 485 extends into the positioning hole 132. The positioning post 485 and the positioning hole 132 are used to limit and position the cup body 41, thereby increasing the connection stability between the cup body 41 and the mounting position 13 and further improving the user experience.

[0149] Specifically, each mounting position 13 has a connecting surface that faces its own opening. The positioning hole 132 is located on the connecting surface. The positioning post 485 is located on the cup body 41 and is positioned opposite to the positioning hole 132. The extension direction of the positioning post 485 is parallel to the placement and removal direction of the wet mist component 4. This ensures the connection stability between the cup body 41 and the mounting position 13, and also ensures that the wet mist component 4 can be easily placed and removed.

[0150] Of course, in order to increase the connection stability between the cup body 41 and the mounting position 13, in other embodiments, one of the cup body 41 and the mounting position 13 is provided with a magnetic sheet, and the other is provided with an iron sheet that can magnetically engage with the magnetic sheet, so as to increase the connection stability between the cup body 41 and the mounting position 13 by utilizing the magnetic engagement of the magnetic sheet and the iron sheet.

[0151] Furthermore, refer to Figure 9 and Figure 26 The lower part of the cup body 41 is provided with a water level probe 486 that extends into the second liquid chamber 419, and the mounting position 13 is provided with a conductive part 133 that can be electrically connected to the water level probe 486.

[0152] Because the lower part of the cup body 41 is provided with a water level probe 486 that extends into the second liquid chamber 419, the water level probe 486 is used to detect the liquid level in the second liquid chamber 419. When the liquid level in the second liquid chamber 419 is lower than the water level probe 486, the water level probe 486 can send a signal to the control module of the control terminal, so that the control module of the control terminal can issue an alarm or terminate the operation of the atomizing structure, so as to avoid the situation where the atomizing structure is not working properly, thereby further improving the user experience.

[0153] This application does not specifically limit the structure of the conductive part 133. Preferably, the conductive part 133 is an elastic contact pin disposed at the mounting position 13 and electrically connected to the control module of the control terminal, so as to ensure the stability of the electrical conduction between the conductive part 133 and the water level probe 486. In other embodiments, the conductive part 133 may also be a conductive block disposed at the mounting position 13.

[0154] In other embodiments, the first liquid cavity 411 and the second liquid cavity 419 may also be respectively provided in the two cup bodies 41, that is, the first liquid cavity 411 and the second liquid cavity 419 are formed by the internal spaces of the two cup bodies 41 respectively.

[0155] Of course, in other embodiments, the design of the first liquid chamber 411 can be omitted so that the control terminal can eliminate the function of humidifying oxygen, or the design of the second liquid chamber 419 can be omitted so that the control terminal can eliminate the function of humidifying the room.

[0156] This application does not impose specific limitations on the atomization structure; preferred options are described below. Figure 9 and Figure 14 The atomizing structure includes a water-absorbing member 44 passing through the cup lid 42 and an atomizing member 45 disposed on the cup lid 42. One bottom end of the water-absorbing member 44 extends into the second liquid-containing cavity 419, and one top end of the water-absorbing member 44 abuts against the bottom of the atomizing member 45, so that the liquid contained in the second liquid-containing cavity 419 moves to the bottom of the atomizing member 45 under the action of the water-absorbing member 44. The cup lid 42 is provided with a mist outlet 424 corresponding to the atomizing member 45.

[0157] It is understandable that the housing 1 is provided with a perforated structure corresponding to the mist outlet 424 so that the atomized liquid sprayed through the mist outlet 424 can move to the outside of the housing 1.

[0158] When the control terminal humidifies the room, the water absorption component 44 delivers the liquid in the second liquid chamber 419 to the bottom of the atomizing component 45 so that the atomizing component 45 atomizes the liquid. The atomized liquid is then sprayed out through the mist outlet 424 to increase the humidity in the room.

[0159] In this application, the liquid contained in the second liquid chamber 419 is transported to the bottom of the atomizing element 45 through the water-absorbing element 44, thereby positioning the atomizing element 45 above the second liquid chamber 419. Compared with the prior art where the atomizing element 45 is placed in the liquid, the water-absorbing element 44 can filter the liquid, reducing the water quality requirements of the atomizing element 45, thereby reducing the user's operating costs. At the same time, it reduces the damage to the atomizing element 45 caused by water quality issues, thus extending the service life of the atomizing element 45 and reducing the failure rate of the wet mist assembly 4.

[0160] In addition, since the atomizing element 45 is located in the cup lid 42, compared with the prior art where the atomizing element 45 is located inside the humidifying cup, the difficulty of repairing and replacing the atomizing element 45 is reduced, thereby achieving the effect of facilitating the repair of the humidifying mist assembly 4.

[0161] This application does not specifically limit the structure of the atomizing element 45. Preferably, the atomizing element 45 is an atomizing sheet to reduce the production cost of the wet fog assembly 4 and ensure the atomization effect on the liquid. In other embodiments, the atomizing element 45 can also be a microporous vibrating membrane, an ultrasonic transducer, or other structures capable of atomizing liquids.

[0162] Preferably, the side of the cup lid 42 is provided with a conductive post that is electrically connected to the atomizing component 45, and the mounting position 13 is provided with an elastic conductive pin that is electrically connected to the conductive post. The elastic conductive pin is electrically connected to the control module of the control terminal, so as to realize the function of powering the atomizing component 45 after the wet mist component 4 is placed in the mounting position 13.

[0163] This application does not specifically limit the structure of the absorbent element 44. Preferably, the absorbent element 44 is an absorbent rod to ensure the stability of its shape and thus guarantee the liquid conveying effect. In other embodiments, the absorbent element 44 can also be a strip of absorbent cotton or absorbent rope.

[0164] Furthermore, refer to Figure 9 , Figure 13 and Figure 14 The atomizing structure also includes a bracket 46 located at the bottom of the cup lid 42. The bracket 46 has a waist-shaped hole 461 on its side. The bracket 46 is sleeved on the outside of the water-absorbing member 44 and can extend into the second liquid-containing cavity 419 through the second liquid inlet 481. An elastic member 462 located at the bottom of the water-absorbing member 44 is provided inside the bracket 46 so that the elastic member 462 applies an upward elastic force to the water-absorbing member 44.

[0165] It is understandable that the bracket 46 is hollow inside so that it can be fitted onto the outside of the absorbent 44; and after the absorbent 44 and the bracket 46 are installed on the cup lid 42, the bottom end of the absorbent 44 abuts against the elastic member 462 and applies downward pressure to the elastic member 462, so that the elastic member 462 is in a deformed state, thereby allowing the elastic member 462 to apply an upward elastic support force to the absorbent 44.

[0166] After the cup lid 42 is installed onto the cup body 41, the bracket 46 and the water-absorbing component 44 enter the second liquid chamber 419 through the second liquid inlet 481, so that the liquid in the second liquid chamber 419 enters the interior of the bracket 46 through the waist-shaped hole 461. The liquid entering the interior of the bracket 46 comes into contact with the water-absorbing component 44 and is transported to the bottom of the atomizing component 45 through the water-absorbing component 44, so that the liquid can be atomized by the atomizing component 45.

[0167] Because the bracket 46 has an elastic element 462 located at the bottom of the water-absorbing element 44, the elastic element 462 can apply an upward elastic force to the water-absorbing element 44. The upward elastic force applied by the elastic element 462 to the water-absorbing element 44 ensures that the water-absorbing element 44 is in contact with the bottom of the atomizing element 45, so that the water-absorbing element 44 and the atomizing element 45 are always in contact. This ensures the atomization effect of the atomizing element 45 on the liquid in the second liquid chamber 419, thereby ensuring the effect of increasing indoor humidity.

[0168] In addition, since the bracket 46 is fitted on the outside of the water-absorbing component 44, it can also protect the water-absorbing component 44 to avoid damage or bending of the water-absorbing component 44 due to friction between the water-absorbing component 44 and the wall of the second liquid inlet 481 during the installation of the cup lid 42, thereby ensuring the service life of the water-absorbing component 44.

[0169] Preferably, multiple waist-shaped holes 461 are provided along the axial direction of the bracket 46, and at least some of the waist-shaped holes 461 are provided in the lower part of the bracket 46, so that when the liquid in the second liquid chamber 419 is low, the water suction member 44 can still transport the liquid in the second liquid chamber 419 to the bottom of the atomizing member 45, thereby reducing the frequency of needing to replenish the liquid in the second liquid chamber 419 and further improving the user experience.

[0170] Preferably, the diameter of the water-absorbing element 44 is smaller than the inner diameter of the bracket 46, so that there is a gap between the periphery of the water-absorbing element 44 and the inner wall of the bracket 46, so as to ensure the water-absorbing element 44 can effectively transport the liquid in the second liquid chamber 419.

[0171] This application does not specifically limit the structure of the elastic element 462. Preferably, the elastic element 462 is a spring disposed inside the bracket 46, with one end of the spring contacting the inner bottom wall of the bracket 46 and the other end of the spring contacting the bottom of the absorbent element 44, so as to ensure the elastic support effect of the elastic element 462 on the absorbent element 44. In other embodiments, the elastic element 462 can also be an elastic sheet, an elastic column, or other elastic structures that can apply an upward elastic support force to the absorbent element 44.

[0172] This application does not specify the installation method of the water-absorbing component 44, but refers to... Figure 14 and Figure 15 The cup lid 42 has a mounting rib 423. The atomizing structure also includes a mounting bracket 47 that passes through the mounting rib 423. The top of the mounting bracket 47 is provided with an edge 471 that abuts against the top of the mounting rib 423. The atomizing element 45 is provided on the top of the mounting bracket 47, and the water-absorbing element 44 passes through the mounting bracket 47.

[0173] Since the water-absorbing component 44 passes through the mounting bracket 47, and the mounting bracket 47 passes through the mounting rib 423, the stability of the water-absorbing component 44 is increased, and the installation difficulty of the water-absorbing component 44 is reduced, thereby improving the installation efficiency of the water-absorbing component 44. Since the top of the mounting bracket 47 is provided with an edge 471, which abuts against the top of the mounting rib 423, the cooperation between the edge 471 and the mounting rib 423 can support the mounting bracket 47, thereby achieving the desired stability. 7 limits the downward movement of the mounting rib 423 to increase the stability of the mounting bracket 47. On the other hand, the edge 471 can be used to cooperate with the top of the mounting rib 423 to position the mounting bracket 47 at the mounting position 13, so as to facilitate the installation of the mounting bracket 47 and improve the installation efficiency of the mounting bracket 47. Since the atomizing element 45 is located at the top of the mounting bracket 47, the mounting bracket 47 can be used to support the atomizing element 45 to increase the stability of the atomizing element 45.

[0174] This application does not specifically limit the structure along edge 471; preferably, refer to... Figure 16 The edge 471 is a rib structure that extends continuously along the circumference of the mounting frame 47 to increase the mating area between the edge 471 and the top of the mounting rib 423, thereby further increasing the stability of the mounting frame 47. In other embodiments, the edge 471 may also be a rib structure that is spaced apart along the circumference of the mounting frame 47.

[0175] Furthermore, refer to Figure 16 A flange 472 is provided extending upward along the edge 471, and the flange 472 is located on the outside of the atomizing element 45.

[0176] Understandably, after the atomizing element 45 is installed on the mounting bracket 47, the periphery of the atomizing element 45 abuts against the flange 472.

[0177] Since a flange 472 is provided extending upward along the edge 471 and is located on the outside of the atomizing element 45, the flange 472 can be used to position the atomizing element 45 to facilitate its installation. On the other hand, the flange 472 can also be used to limit the atomizing element 45 to increase the connection stability between the atomizing element 45 and the mounting bracket 47, thereby ensuring the stability of the atomizing element 45 and thus ensuring the atomization effect of the atomizing element 45 on the liquid.

[0178] This application does not specifically limit the structure of the flange 472. Preferably, the flange 472 is a rib structure that extends continuously along the circumference of the edge 471 to increase the contact area between the flange 472 and the atomizing element 45, thereby further increasing the stability of the atomizing element 45. In other embodiments, the flange 472 may also be a rib structure that is spaced apart along the circumference of the edge 471.

[0179] The better one is to refer to Figure 16 The mounting bracket 47 has a receiving groove on its outer periphery, and a sealing ring 473 is provided in the receiving groove. At least a portion of the sealing ring 473 protrudes from the outer periphery of the mounting bracket 47. After the mounting bracket 47 is installed on the mounting rib 423, the outer periphery of the sealing ring 473 abuts against the inner wall of the mounting rib 423. This increases the connection stability between the mounting bracket 47 and the mounting rib 423, and also increases the sealing between the mounting bracket 47 and the mounting rib 423.

[0180] This application does not specifically limit the formation of the receiving groove. Preferably, two annular ribs 16 are provided at intervals on the outer periphery of the mounting bracket 47, and the receiving groove is formed between the two annular ribs 16 to facilitate the installation of the mounting bracket 47 on the mounting rib position 423. In other embodiments, the receiving groove can also be a groove-shaped structure formed by cutting or reserving along the circumference of the mounting bracket 47.

[0181] This application does not specify the location of the mist outlet 424; preferably, refer to... Figure 7 , Figure 9 and Figure 14 The mist outlet 424 is located at the corner of the top front side of the cup lid 42. The top of the mounting bracket 47 has a mounting surface, which is perpendicular to the central axis of the mist outlet 424. The atomizing element 45 abuts against the mounting surface.

[0182] It is understandable that the top of the mounting rib 423 is inclined to the mounting surface so that the edge 471 can fully contact the top of the mounting rib 423 to increase the stability of the mounting bracket 47.

[0183] The mounting surface is perpendicular to the central axis of the mist outlet 424, and the atomizing element 45 abuts against the mounting surface, thereby making the atomizing element 45 perpendicular to the central axis of the mist outlet 424. This allows the atomized liquid generated by the atomizing element 45 to be sprayed directly through the mist outlet 424, thereby improving the spraying efficiency of the atomized liquid. At the same time, it avoids the accumulation of atomized liquid inside the cup lid 42, ensuring the dryness of the inside of the cup lid 42 and preventing the occurrence of bacteria growth due to the dampness inside the cup lid 42.

[0184] Since control terminals are generally installed on walls, this application places the mist outlet 424 at the corner of the top front side of the cup lid 42. The atomized liquid generated by the atomizing element 45 is then sprayed upwards at an angle, causing the atomizing element 45 sprayed through the mist outlet 424 to move away from the wall. This increases the distance between the atomized liquid sprayed through the mist outlet 424 and the wall, preventing the wall from becoming too damp and prone to bacterial growth due to the atomized liquid easily adhering to the wall. It also prevents the latex paint, putty, and other decorative layers from easily peeling off due to the wall being too damp, thereby further improving the user experience.

[0185] In other implementation examples, the mist outlet 424 may also be located directly above the cup lid 42.

[0186] This application does not specify a particular method for fixing the atomizing element 45; preferably, refer to... Figure 9 and Figure 13 The cup lid 42 includes a lower lid 421 and an upper lid 422 disposed on the lower lid 421. The mounting rib 423 is disposed on the lower lid 421. The atomizing element 45 is located between the edge 471 and the upper lid 422 to compress and fix the atomizing element 45.

[0187] It is understandable that the mist outlet 424 is located on the upper cover 422 so that the atomizing element 45 can be fixed by the mutual compression between the upper cover 422 and the edge 471.

[0188] Since the mounting rib 423 is located on the lower cover 421 and the atomizing element 45 is located between the edge 471 and the upper cover 422, the atomizing element 45 can be fixed by the mutual compression of the edge 471 and the upper cover 422. On the one hand, this ensures the stability of the atomizing element 45, so as to ensure the humidification effect of the wet mist assembly 4 on the room. On the other hand, it avoids the need to set up a separate component to fix the atomizing element 45, thereby reducing the production cost of the wet mist assembly 4 and improving the assembly efficiency of the wet mist assembly 4.

[0189] Preferably, the mounting rib 423 is a hollow columnar structure extending upward from the lower cover 421 to ensure the connection stability between the mounting bracket 47 and the mounting rib 423.

[0190] In other implementation examples, the atomizing element 45 may also be fixedly connected to the mounting bracket 47 by screws or other fastening structures.

[0191] This application does not specify a particular method for fixing the upper cover 422 and the lower cover 421. The upper cover 422 is fixedly connected to the lower cover 421 by screws. This increases the stability of the connection between the upper cover 422 and the lower cover 421, and also facilitates the disassembly and assembly of the cup lid 42, thereby facilitating the replacement of the atomizing component 45. In other embodiments, the upper cover 422 can also be fixedly connected to the lower cover 421 by a snap-fit ​​method.

[0192] In other embodiments, the design of the mounting rib 423 and the mounting bracket 47 can be omitted, and the water-absorbing component 44 can be directly inserted into the cup lid 42 and fixed by the interference fit between the water-absorbing component 44 and the cup lid 42.

[0193] In a preferred embodiment, refer to Figure 13 The cup lid 42 has a first sealing post 425 that can extend into the first liquid inlet 416 and a second sealing post 426 that can extend into the second liquid inlet 481. The water-absorbing member 44 passes through the second sealing post 426, and the bracket 46 is connected to the second sealing post 426.

[0194] It is understandable that the first sealing post 425 and the second sealing post 426 are both located at the bottom of the lower cover 421.

[0195] Since the cup lid 42 has a first sealing post 425 that can extend into the first liquid inlet 416 and a second sealing post 426 that can extend into the second liquid inlet 481, after the cup lid 42 is installed onto the cup body 411, the first sealing post 425 extends into the first liquid inlet 416 and the second sealing post 426 extends into the second liquid inlet 481 to achieve sealing of the first liquid inlet 416 and the second liquid inlet 481, thereby ensuring the sealing of the first liquid chamber 411 and the second liquid chamber 419.

[0196] Since the water-absorbing component 44 passes through the second sealing post 426, it extends into the second liquid-containing cavity 419 through the second sealing post 426. On the one hand, this ensures the sealing effect of the second sealing post 426 on the second liquid inlet 481. On the other hand, by integrating the second sealing post 426 and the water-absorbing component 44 in the same position, the area of ​​the second liquid inlet 481 is reduced, which further facilitates the miniaturization design of the wet mist component 4.

[0197] Since the bracket 46 is connected to the second sealing post 426, the connection area between the bracket 46 and the cup lid 42 can be increased to ensure the stability of the bracket 46, thereby ensuring the support and protection effect of the bracket 46 on the water-absorbing part 44.

[0198] The better one is to refer to Figure 14 Both the first sealing post 425 and the second sealing post 426 have annular grooves on their outer peripheries, and sealing rings 427 are disposed in the annular grooves. At least a portion of the sealing ring 427 protrudes from the corresponding first sealing post 425 or second sealing post 426. This allows the sealing ring 427 on the first sealing post 425 to seal the gap between the first sealing post 425 and the wall of the first liquid inlet 416, thereby improving the sealing performance of the first liquid cavity 411. The sealing ring 427 on the second sealing post 426 can... The sealing ring 427 on the first sealing post 425 can seal the gap between the second sealing post 426 and the wall of the second liquid inlet 481, thereby improving the sealing performance of the second liquid chamber 419. On the other hand, the sealing ring 427 on the first sealing post 425 can also increase the connection stability between the first sealing post 425 and the wall of the first liquid inlet 416, and the sealing ring 427 on the second sealing post 426 can also increase the connection stability between the second sealing post 426 and the wall of the second liquid inlet 481, thereby increasing the connection stability between the cup lid 42 and the cup body 41.

[0199] This application does not specify the method of fixing the bracket 46 and the second sealing post 426. Preferably, refer to Figure 15 The interior of the second sealing post 426 has a protrusion 428, and the bracket 46 is provided with a stop 463 that abuts against the top of the protrusion 428 and a limiting part 464 that abuts against the bottom of the second sealing post 426.

[0200] When installing the bracket 46, first align the bracket 46 with the second sealing post 426, then apply pressure to the bracket 46 in the direction of the second sealing post 426 to move the bracket 46 in that direction, causing the stop 463 to abut against the protrusion 428. Continue applying pressure to the bracket 46, causing both the stop 463 and the protrusion 428 to deform, ultimately allowing the stop 463 to pass over the protrusion 428. After passing the protrusion 428, the stop 463 and the protrusion 428 return to their original shape. At this time, the stop 463 abuts against the top of the protrusion 428, and the limiting part 464 abuts against the bottom of the second sealing post 426. The bracket 46 is fixed by the stop 463 and the protrusion 428 stop 468 stop 464 and the bottom stop 46 of the second sealing post 426. This increases the stability of the bracket 46 and reduces the difficulty of installing the bracket 46.

[0201] The better one is to refer to Figure 9 The top end of the bracket 46 is provided with a partition groove 465 so that when the bracket 46 is installed, the top end of the bracket 46 can deform under the action of the stop part 463, thereby reducing the difficulty of installing the bracket 46.

[0202] This application does not specifically limit the structure of the protrusion 428, the stop 463, and the limiting part 464. Preferably, the protrusion 428 is an annular structure that extends continuously along the circumference of the second sealing post 426, and the stop 463 and the limiting part 464 are both annular structures that extend continuously along the circumference of the bracket 46, so as to increase the stop mating area between the bracket 46 and the second sealing post 426, thereby increasing the connection stability between the bracket 46 and the second sealing post 426. In other embodiments, the protrusions 428 are block structures spaced circumferentially along the second sealing post 426, and the stops 463 are block structures spaced circumferentially along the bracket 46. The gap between two adjacent protrusions 428 allows the stops 463 to pass through, so that when installing the bracket 46, the stops 463 can first pass through the gap between the two protrusions 428 before the bracket 46 is rotated so that the stops 463 and the protrusions 428 are axially opposite each other, thereby reducing the difficulty of installing the bracket 46. The limiting part 464 is also a block structure spaced circumferentially along the bracket 46, thereby reducing the production cost of the bracket 46.

[0203] In other embodiments, the atomizing structure may also be other structures capable of atomizing the liquid in the second liquid chamber 419.

[0204] This application does not specify the location of the oxygen inlet 417; preferably, refer to... Figure 11 and Figure 12 The wet mist assembly 4 includes a cup body 41, a first liquid chamber 411 and a second liquid chamber 419, both of which are located inside the cup body 41. The cup body 41 is provided with an oxygen inlet channel 487 that communicates with the first liquid chamber 411. The oxygen inlet channel 487 extends from top to bottom, and the oxygen inlet 417 communicates with the oxygen inlet channel 487 so that the oxygen entering the oxygen inlet channel 487 through the oxygen inlet 417 enters the first liquid chamber 411 at the bottom.

[0205] It is understood that in this embodiment, the oxygen inlet 417 is located on the side of the cup body 41 and is located on the upper part of the cup body 41. The oxygen inlet 417 and the oxygen outlet 418 are located on two opposite sides of the cup body 41. An oxygen inlet nozzle is provided at the oxygen inlet 417 and extends outward. The mounting position 13 is provided with a connecting nozzle that can connect with the oxygen inlet nozzle, so that after the wet mist assembly 4 is installed in the mounting position 13, the first liquid chamber 411 is connected to the flow control valve 5 through the oxygen inlet nozzle and the connecting nozzle.

[0206] When the control terminal of this application is working, oxygen enters the oxygen inlet channel 487 through the oxygen inlet 417. Since the oxygen inlet channel 487 extends from top to bottom, the oxygen flows downward after entering the oxygen inlet channel 487 and enters the first liquid chamber 411 at the bottom. This increases the flow path of oxygen in the first liquid chamber 411 to improve the humidification effect of oxygen. On the other hand, it ensures that the oxygen must pass through the liquid contained in the first liquid chamber 411 before being discharged through the oxygen outlet 418, thereby further improving the humidification effect of oxygen.

[0207] Preferably, the cross-sectional area of ​​the oxygen inlet channel 487 is smaller than the cross-sectional area of ​​the first liquid chamber 411, so as to ensure the pressure when oxygen enters the first liquid chamber 411, so that the oxygen can rush out of the liquid surface of the liquid contained in the first liquid chamber 411, thereby ensuring the smoothness of the user's inhalation of humidified oxygen.

[0208] This application does not specifically limit the positional relationship between the oxygen inlet channel 487 and the first liquid chamber 411. Preferably, refer to... Figure 11 and Figure 12 The oxygen inlet channel 487 is located inside the cup body 41, meaning it is situated within the first liquid chamber 411. This reduces the volume of the cup body 41, thereby facilitating the miniaturization of the wet mist assembly 4. In other embodiments, the oxygen inlet channel 487 can also be located outside the cup body 41, meaning it is independent of the first liquid chamber 411 but connected at the bottom.

[0209] Furthermore, refer to Figure 12 and Figure 14 A gas baffle plate 412 is provided at the bottom of the first liquid chamber 411. The gas baffle plate 412 is provided with multiple dispersion holes 414. A connecting cavity 413 is formed between the gas baffle plate 412 and the cup body 41. The lower end of the oxygen inlet channel 487 is connected to the connecting cavity 413.

[0210] Oxygen entering the oxygen inlet channel 487 flows downwards along the channel, allowing it to enter the connecting cavity 413. The oxygen in the connecting cavity 413 then enters the first liquid chamber 411 through the dispersion holes 414 on the baffle plate 412. This further disperses the airflow as the oxygen enters the first liquid chamber 411, reducing the oxygen flow pressure and preventing large air bubbles from forming in the liquid. This avoids the liquid from bursting and splashing to the oxygen outlet 418, which would then flow through the nasal cannula. The phenomenon described above reduces liquid loss from the first liquid chamber 411, extending the duration for which the liquid in the first liquid chamber 411 continuously humidifies oxygen, thus reducing the frequency at which the user needs to replenish the liquid in the first liquid chamber 411. On the other hand, it prevents the liquid in the first liquid chamber 411 from entering the user's respiratory tract through the nasal cannula and affecting the user experience. Furthermore, it reduces the volume of bubbles generated after oxygen enters the first liquid chamber 411, thereby reducing the noise generated when the humidification component 4 is working, and thus greatly improving the user experience.

[0211] In other embodiments, the oxygen inlet 417 may also be located at the bottom of the cup body 41, and a one-way valve is provided at the oxygen inlet 417 so that oxygen can enter the first liquid chamber 411 through the one-way valve, while the liquid in the first liquid chamber 411 cannot be discharged through the one-way valve.

[0212] In a preferred embodiment, refer to Figure 12 and Figure 14 A baffle plate 415 is provided on the upper part of the first liquid chamber 411, located below the oxygen outlet 418. The end of the baffle plate 415 away from the oxygen outlet 418 is spaced apart from the cavity wall of the first liquid chamber 411, and the end of the baffle plate 415 away from the oxygen outlet 418 is inclined downward.

[0213] Understandably, except for the end of the baffle plate 415 that is far away from the oxygen outlet 418, the outer circumferential surface of the baffle plate 415 is fixedly connected to the cavity wall of the first liquid chamber 411 to increase the baffle plate 415's blocking effect on the splashed liquid.

[0214] Because a baffle plate 415 is provided on the upper part of the first liquid chamber 411, located below the oxygen outlet 418, and the end of the baffle plate 415 away from the oxygen outlet 418 is spaced apart from the cavity wall of the first liquid chamber 411, the baffle plate 415 can block the liquid generated by oxygen rushing out of the liquid surface, so as to avoid the phenomenon of liquid splashing to the oxygen outlet 418, thereby preventing the phenomenon of liquid entering the oxygen inhalation tube connected to the oxygen outlet 418, so as to improve the safety and user experience when the user inhales oxygen through the nasal cannula.

[0215] Furthermore, since the end of the baffle plate 415 away from the oxygen outlet 418 is inclined downward, the liquid that splashes and adheres to the baffle plate 415 can fall down at the end of the baffle plate 415 away from the oxygen outlet 418 and return to the bottom of the first liquid chamber 411. This avoids the situation where the amount of liquid at the bottom of the first liquid chamber 411 decreases due to the liquid adhering to the baffle plate 415, thereby ensuring the amount of liquid at the bottom of the first liquid chamber 411 and thus ensuring the humidification effect of oxygen.

[0216] Meanwhile, since the end of the baffle plate 415 away from the oxygen outlet 418 is inclined downward, the liquid falling above the baffle plate 415 can also flow back to the bottom of the first liquid chamber 411 at the end of the baffle plate 415 away from the oxygen outlet 418.

[0217] This application does not specifically limit the structure of the water baffle 415; preferably, refer to... Figure 12 The baffle plate 415 is inclined downwards along the direction away from the oxygen outlet 418, and the end of the baffle plate 415 away from the oxygen outlet 418 has a guide section. The guide section is inclined downwards along the direction away from the oxygen outlet 418, and the inclination angle of the guide section is greater than the inclination angle of the baffle plate 415, so as to improve the guiding effect on the liquid adhering to the baffle plate 415. In other embodiments, the design of the guide section can be omitted.

[0218] In a preferred embodiment, refer to Figures 19 to 24 The diffused gas box 3 has multiple air outlets 31, and the shell 1 is provided with annular ribs 16 surrounding the multiple air outlets 31. The shell 1, the diffused gas box 3, and the annular ribs 16 together form a diffused cavity. The shell 1 is provided with multiple diffused holes 161 communicating with the diffused cavity. The number of diffused holes 161 is greater than the number of air outlets 31.

[0219] After oxygen enters the diffusion chamber 3, it diffuses within the chamber and eventually enters the diffusion cavity through the outlet 31. The oxygen in the diffusion cavity diffuses within the cavity and is eventually released into the indoor environment through the diffusion hole 161 in a diffused manner.

[0220] Because oxygen undergoes multiple diffusion processes when released into the room through diffusion, the kinetic energy of the oxygen as it exits through the diffusion hole 161 is reduced, thereby reducing the noise generated when the diffusion box 3 diffuses and releases oxygen, and thus improving the user experience.

[0221] Furthermore, since the number of diffusion holes 161 is greater than the number of air outlet holes 31, the oxygen in the diffusion chamber is released through multiple diffusion holes 161, thereby improving the diffusion effect of the diffusion gas box 3 on oxygen and further improving the user experience.

[0222] Preferably, the diameter of the outlet hole 31 is larger than the diameter of the diffusion hole 161 to ensure the efficiency of oxygen entering the diffusion chamber, thereby ensuring the diffusion effect of the diffusion gas box 3 on oxygen.

[0223] This application does not specify the connection method between the annular rib 16 and the diffused air box 3. Preferably, refer to... Figures 19 to 22 The outside of the diffused gas box 3 is provided with connecting ribs 32 surrounding multiple air outlets 31. One of the connecting ribs 32 and the annular ribs 16 is provided with a sealing groove 321, and the other is provided with a sealing rib 162 extending into the sealing groove 321.

[0224] It is understandable that the connecting rib 32 and the annular rib 16 are arranged opposite each other so that the annular rib 16 can be mated and cooperate with the connecting rib 32.

[0225] Because the diffused air box 3 is provided with connecting ribs 32 surrounding multiple air outlets 31, the volume of the diffused cavity is further increased, thereby further reducing the kinetic energy of oxygen when it is discharged through the diffused holes 161, and thus further improving the noise reduction effect of the diffused air box 3.

[0226] Furthermore, since one of the connecting rib 32 and the annular rib 16 is provided with a sealing groove 321, and the other is provided with a sealing rib 162 extending into the sealing groove 321, on the one hand, the cooperation between the sealing rib 162 and the sealing groove 321 can position the shell 1 and the diffused gas box 3, thereby reducing the difficulty of assembling the shell 1 and the diffused gas box 3 together, improving the assembly efficiency of the diffused gas box 3, and thus reducing the assembly cost of the diffused gas box 3. On the other hand, the cooperation between the sealing groove 321 and the sealing rib 162 can also increase the connection sealing between the connecting rib 32 and the annular rib 16, so as to ensure the airtightness of the diffusion cavity.

[0227] It should be noted that, in order to increase the connection stability between the housing 1 and the diffused gas box 3, when assembling the housing 1 onto the diffused gas box 3, it is necessary to apply glue to the sealing groove 321 in advance, so as to use the glue to fix the sealing rib 162 to the groove wall of the sealing groove 321 together, thereby increasing the connection stability between the housing 1 and the diffused gas box 3.

[0228] Specifically, the sealing groove 321 is provided on the end face of the connecting rib 32 facing the housing 1 and extends continuously along the circumference of the connecting rib 32, and the sealing rib 162 is provided on the end face of the annular rib 16 facing the diffused gas box 3 and extends continuously along the circumference of the annular rib 16.

[0229] In other embodiments, the annular rib 16 can be directly fixed to the end face of the diffused gas box 3 facing the housing 1 using glue; or, a groove for accommodating the annular rib 16 can be provided on the end face of the diffused gas box 3 facing the housing 1, so that the end of the annular rib 16 away from the housing 1 is inserted into the groove and the annular rib 16 is fixedly connected to the groove wall using glue.

[0230] Furthermore, refer to Figure 20 , Figure 21 and Figure 23 The diffused gas box 3 has an air inlet end and an air outlet end. At least one side of the air outlet end of the diffused gas box 3 is recessed into the interior of the diffused gas box 3 and a clearance notch 33 is provided. Multiple air outlets 31 are provided on the wall surface of the clearance notch 33.

[0231] Since multiple air outlets 31 are located on the wall of the clearance notch 33, after the diffused air box 3 is assembled into the housing 1, the annular rib 16 can be located in the clearance notch 33 to reduce the volume of the control terminal, thereby facilitating the miniaturization of the control terminal.

[0232] Preferably, the diffused gas box 3 is provided with clearance notches 33 on both sides of the gas outlet end, and multiple gas outlets 31 are provided on the wall of one of the clearance notches 33, so that one side of the diffused gas box 3 avoids the annular rib 16, and the clearance notch 33 on the other side of the diffused gas box 3 avoids other components inside the control terminal, so as to facilitate the miniaturization design of the control terminal.

[0233] Of course, in other embodiments, the design of the avoidance notch 33 can be omitted so that the appearance of the diffused gas box 3 is more regular.

[0234] Furthermore, the diffused air box 3 has an air-containing cavity 34 inside, which is filled with noise-reducing cotton and has multiple partitions for dividing the air-containing cavity 34 into multiple buffer chambers. Each partition forms a communication port with the cavity wall of the air-containing cavity 34, and adjacent two communication ports are staggered.

[0235] Because the gas chamber 34 is filled with noise-reducing cotton, the oxygen entering the gas chamber 34 moves inside the noise-reducing cotton, thereby reducing the noise generated by the contact friction between the oxygen flow and the cavity wall of the gas chamber 34, and further improving the noise reduction effect of the diffused gas box 3.

[0236] Furthermore, since each partition forms a communication port with the cavity wall of the gas chamber 34, and adjacent communication ports are staggered, this increases the movement path of oxygen in the gas chamber 34, thereby increasing the kinetic energy consumption of oxygen flowing in the gas chamber 34, further reducing the kinetic energy of oxygen when it is discharged through the diffusion hole 161, and thus further improving the noise reduction effect of the diffusion gas box 3. On the other hand, it increases the number of times oxygen diffuses in the gas chamber 34, further reducing the kinetic energy of oxygen, and thus further improving the noise reduction effect of the diffusion gas box 3.

[0237] This application does not specifically limit the structure of the noise-reducing cotton. Preferably, the noise-reducing cotton is a sponge to ensure the shape stability of the noise-reducing cotton, thereby ensuring the noise reduction effect of the diffused air box 3. In other embodiments, the noise-reducing cotton can also be cotton wool, mixed fiber cotton, or other materials with noise-reducing properties.

[0238] It should be noted that, in addition to being formed between the partition and the cavity wall of the air chamber 34, the connecting port can also be formed by a hole structure pre-reserved on the partition.

[0239] This application does not specify the particular arrangement of multiple buffer cavities; preferably, refer to... Figure 24 and Figure 25 The diffused gas box 3 has a length direction, and multiple buffer chambers are arranged sequentially along the length direction of the diffused gas box 3. The diffused gas box 3 also has an air inlet, and the air inlet is connected to a buffer chamber located at one end of the length direction of the diffused gas box 3. Multiple air outlets 31 are all connected to a buffer chamber located at the other end of the length direction of the diffused gas box 3.

[0240] Because multiple buffer chambers are arranged sequentially along the length of the diffused gas box 3, the distribution of buffer chambers inside the diffused gas box 3 becomes more regular, thereby further reducing the production difficulty of the diffused gas box 3. Since the air inlet is connected to the buffer chamber located at one end of the length of the diffused gas box 3, and multiple air outlets 31 are all connected to the buffer chamber located at the other end of the length of the diffused gas box 3, the oxygen can pass through multiple buffer chambers sequentially when flowing in the gas chamber 34, so as to ensure the movement path of the oxygen in the gas chamber 34, thereby ensuring the consumption effect of oxygen kinetic energy, and thus ensuring the noise reduction effect of the diffused gas box 3.

[0241] In other implementation examples, multiple buffer chambers may be arranged sequentially along the circumference of the diffused gas box 3, or multiple buffer chambers may be divided into two rows, with the two rows of buffer chambers staggered along the length of the diffused gas box 3.

[0242] This application does not specifically limit the structure of the diffused gas box 3 and the partition; preferably, refer to... Figure 20 , Figure 21 , Figure 24 and Figure 25The diffused gas box 3 includes a first outer shell 35 and a second outer shell 36 that together form a gas cavity 34. The partition includes a first partition 351 disposed on the first outer shell 35 and a second partition 361 disposed on the second outer shell 36. The first partition 351 and the second partition 361 are disposed opposite to each other. The communication port includes a first communication port 353 and a second communication port 363 that is staggered with the first communication port 353 in the length direction of the diffused gas box 3. One of the two adjacent first partitions 351 forms a first communication port 353 between itself and the cavity wall of the gas cavity 34. One of the two adjacent second partitions 361 forms a second communication port 363 between itself and the cavity wall of the gas cavity 34.

[0243] It should be noted that the relative arrangement of the first partition 351 and the second partition 361 mentioned above means that after the first outer shell 35 and the second outer shell 36 are assembled together, the first partition 351 and the second partition 361 are arranged in a one-to-one correspondence, and the first partition 351 and its corresponding second partition 361 abut against each other.

[0244] Since the first connecting port 353 and the second connecting port 363 are staggered along the length of the diffused gas box 3, and a first connecting port 353 is formed between one of the two adjacent first partitions 351 and the cavity wall of the gas chamber 34, and a second connecting port 363 is formed between one of the two adjacent second partitions 361 and the cavity wall of the gas chamber 34, the movement path of oxygen in the gas chamber 34 is further increased, thereby further improving the kinetic energy consumption of oxygen in the gas chamber 34. This further reduces the kinetic energy of oxygen when it is discharged from the diffused cavity through the diffused hole 161, thereby further improving the noise reduction effect of the diffused gas box 3 and further improving the user experience.

[0245] Preferably, the first connecting port 353 is formed by the gap between the top of the first partition 351 and the top wall of the gas cavity 34, and the second connecting port 363 is formed by the gap between the bottom of the second partition 361 and the bottom wall of the gas cavity 34, so as to further increase the movement path of oxygen in the gas cavity 34, thereby further improving the consumption effect of oxygen kinetic energy, and further improving the noise reduction effect of the diffused gas box 3.

[0246] In this embodiment, the location of the multiple air outlets 31 and the air inlets is not specifically limited. Both can be located in the first housing 35 or in the second housing 36. The accompanying drawings of this application show that the multiple air outlets 31 and the air inlets are located in the first housing 35.

[0247] In other implementation examples, the partition can also be an integral structure, with the partition disposed in the first housing 35 or the second housing 36, and the partition protruding from the first housing 35 or the second housing 36 to which it is attached, so that after the first housing 35 and the second housing 36 are assembled together, the partition extends into the second housing 36 or the first housing 35.

[0248] This application does not specifically limit the connection method between the first outer shell 35 and the second outer shell 36. Preferably, refer to... Figure 24 and Figure 25 The first outer shell 35 has a first mating surface facing the second outer shell 36, and the second outer shell 36 has a second mating surface facing the first outer shell 35. One of the first mating surface and the second mating surface is provided with a positioning groove 352, and the other of the two is provided with a positioning rib 362 extending into the positioning groove 352.

[0249] Since one of the first mating surface and the second mating surface is provided with a positioning groove 352, and the other of the two is provided with a positioning rib 362 extending into the positioning groove 352, on the one hand, the positioning rib 362 and the positioning groove 352 can be used to limit the first outer shell 35 and the second outer shell 36, thereby reducing the difficulty of assembling the first outer shell 35 and the second outer shell 36 together and improving the assembly efficiency of the diffused gas box 3. On the other hand, the cooperation between the positioning rib 362 and the positioning groove 352 can also increase the sealing between the first outer shell 35 and the second outer shell 36, thereby ensuring the airtightness of the gas cavity 34.

[0250] Specifically, the positioning groove 352 is provided on the first mating surface and extends continuously along the circumference of the first outer shell 35, and the positioning rib 362 is provided on the second mating surface and extends continuously along the circumference of the second outer shell 36.

[0251] It should be noted that, in order to increase the connection stability of the first outer shell 35 and the second outer shell 36, when assembling the first outer shell 35 and the second outer shell 36, it is necessary to apply glue to the positioning groove 352 in advance, so as to use the glue to fix the positioning rib 362 to the groove wall of the positioning groove 352 together, thereby increasing the connection stability of the first outer shell 35 and the second outer shell 36.

[0252] In other embodiments, the diffused gas box 3 may also include a housing with an opening and a cover disposed at the opening.

[0253] In a preferred embodiment, refer to Figure 21 The diffused gas box 3 has an air inlet that communicates with the gas chamber 34. An air inlet nozzle 37 extends from the air inlet. The air inlet nozzle 37 is provided with an air inlet pipe 371 that communicates with the regulating valve 2. A flow regulator 372 is provided in the air inlet pipe 371.

[0254] Understandably, the air inlet is located at the air inlet end of the diffused air box 3.

[0255] Because an air inlet nozzle 37 is provided at the air inlet, it facilitates the connection between the air inlet pipe 371 and the air inlet, thereby reducing the assembly difficulty of the control terminal. Because a flow regulator 372 is provided in the air inlet pipe 371, the flow rate and pressure of the oxygen in the input gas chamber 34 can be adjusted by the flow regulator 372 to reduce the pressure of the oxygen entering the gas chamber 34, thereby further improving the noise reduction effect on the diffused gas box 3.

[0256] This application does not specifically limit the structure of the flow regulator 372. Preferably, the flow regulator 372 is an orifice valve to ensure the regulation effect on oxygen flow and pressure. In other embodiments, the flow regulator 372 can also be a needle valve or other structures capable of regulating flow and pressure.

[0257] Preferably, the outer side of the air inlet nozzle 37 away from the air chamber 34 is provided with a boss, and the diameter of the boss gradually decreases along the direction away from the air chamber 34. On the one hand, this facilitates the connection of the air inlet pipe 371 to the air inlet nozzle 37, and on the other hand, it increases the connection stability between the air inlet pipe 371 and the air inlet nozzle 37.

[0258] In a preferred embodiment, the interior of the housing 1 has a surrounding rib 17, and a receiving cavity is formed between the surrounding rib 17 and the housing 1. The housing 1 is provided with a temperature and humidity detection hole 171 communicating with the receiving cavity. The control terminal also includes a temperature and humidity sensor located in the receiving cavity, thereby isolating the temperature and humidity sensor from other components inside the housing 1 to avoid the influence of heat generated by other components inside the housing 1 on the temperature and humidity sensor's indoor temperature detection, thereby improving the accuracy of the temperature and humidity sensor's indoor temperature detection.

[0259] In a preferred embodiment, refer to Figure 26 The housing 1 has a front side and a rear side opposite to the front side. The front side of the housing 1 has a display and operation area. The rear side of the housing 1 is provided with a pipeline groove 18. The groove wall of the pipeline groove 18 is provided with a terminal air inlet 181 and a terminal hole 182.

[0260] It is understood that the control terminal also includes a display screen and operation buttons located in the display and operation area. The pipeline groove 18 is formed by the rear side of the housing 1 being recessed forward. The pipeline connecting the regulating valve 2 and the oxygen generator can be hidden in the pipeline groove 18 and extend into the mounting cavity 11 through the terminal air inlet 181. The electrical terminals of the control module can extend through the terminal hole 182 for the wiring harness connecting the control module and the oxygen generator, which can also be hidden in the pipeline groove 18.

[0261] Since the rear side of the housing 1 is provided with a pipeline groove 18, and the groove wall of the pipeline groove 18 is provided with a terminal air inlet 181 and a terminal hole 182, the pipeline connecting the oxygen generator and the control terminal can be placed in the pipeline groove 18 so that the rear side of the housing 1 can completely abut against the wall or other mounting surface to ensure the stability of the control terminal.

[0262] Preferably, the pipeline groove 18 is arranged opposite to the clearance notch 33 on the side of the diffused gas box 3 away from the diffused hole 161, so that the diffused gas box 3 can avoid the pipeline groove 18, thereby reducing the size of the control terminal.

[0263] In a preferred embodiment, refer to Figure 1 , Figure 2 , Figure 4 and Figure 19 The control terminal also includes an oxygen concentration sensor, which is located in the mounting cavity 11. The housing 1 is provided with an oxygen concentration detection hole 19 that communicates with the mounting cavity 11, corresponding to the oxygen concentration sensor.

[0264] Since the control terminal also includes an oxygen concentration sensor, it can detect the indoor oxygen concentration, thereby increasing the flexibility of the control terminal. At the same time, the oxygen concentration sensor can also send an oxygen concentration signal to the control module of the control terminal, so that the control module can adjust the oxygen generator and regulating valve 2 according to the oxygen concentration signal, ultimately keeping the indoor oxygen concentration within an optimal range, thereby improving the user experience.

[0265] Preferably, the oxygen concentration sensor is located in the upper part of the mounting cavity 11, and the oxygen concentration detection hole 19 is located in the top of the housing 1, so as to improve the accuracy of oxygen concentration detection.

[0266] In a preferred embodiment, refer to Figure 1 and Figure 2 The control terminal also includes a wireless signal receiving sensor 191 located in the mounting cavity 11, which can then send signals to the control terminal wirelessly, so as to facilitate the user to control the control terminal. On the one hand, it increases the flexibility of the control terminal, and on the other hand, it improves the user experience.

[0267] This application does not specifically limit the structure of the wireless signal receiving sensor 191. Preferably, the wireless signal receiving sensor 191 is an infrared receiving sensor, which can transmit signals to the control terminal via remote control, and the housing 1 is provided with a hole for infrared light to pass through corresponding to the infrared receiving sensor. In other embodiments, the wireless signal receiving sensor 191 can also be a radio frequency receiving sensor, which can transmit signals to the control terminal via Bluetooth, network, etc., or it can be a combination of multiple wireless signal receiving sensors 191, which can transmit signals to the control terminal in multiple ways.

[0269] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0270] The above description is merely an embodiment of this application and is not intended to limit the scope of this application.
