Description

Technical Field

[0001] This application belongs to the technical field of medical devices, specifically relating to a humidification cup for an oxygen concentrator and an oxygen concentrator. Background Technology

[0002] Oxygen concentrators are one of the commonly used medical devices in medical institutions. They can continuously supply oxygen to provide oxygen therapy services to patients. In order to improve the comfort of patients inhaling oxygen, oxygen concentrators are usually equipped with humidification devices to humidify the oxygen with humidifying liquid before it is supplied to patients for inhalation.

[0003] Currently, the humidification device contains humidifying liquid. An air inlet in the humidification cup is connected to an air guide tube that extends into the humidifying liquid. Oxygen enters the humidifying liquid through this tube, causing bubbles to form. These bubbles then rise to the surface of the humidifying liquid and burst, humidifying the oxygen. Finally, the humidified oxygen flows out through the outlet and into the nasal cannula to the user. Because the bubbles burst at the surface of the humidifying liquid, this generates considerable noise. Furthermore, when there is a large amount of humidifying liquid in the humidification cup, the bursting of bubbles can cause water to splash, potentially allowing humidifying liquid to enter the outlet and flow with the humidified oxygen to the user, thus affecting the user experience. Utility Model Content

[0004] This application provides a humidification cup for an oxygen concentrator to reduce the noise generated during operation and prevent the humidification liquid from flowing to the user end, thereby improving the user experience.

[0005] The technical solution adopted in this application is as follows:

[0006] A humidification cup for an oxygen concentrator, comprising:

[0007] The cup body has an internal cavity;

[0008] A separator is provided in the accommodating cavity and divides the accommodating cavity into a liquid-containing cavity for holding humidifying liquid and a humidifying cavity for humidifying oxygen.

[0009] A cup lid is provided on the cup body, and the cup lid has an air inlet and an air outlet, both of which are connected to the humidification chamber.

[0010] An atomizing element is disposed on the separator and is used to atomize the humidifying liquid in the liquid-containing chamber. The humidifying liquid atomized by the atomizing element enters the humidification chamber to humidify the oxygen entering the humidification chamber.

[0011] By adopting the above technical solution, when the humidification cup in this application is working, the atomizing component atomizes the humidifying liquid contained in the liquid chamber, so that the atomized humidifying liquid enters the humidification chamber. Oxygen enters the humidification chamber through the air inlet and comes into contact with the atomized humidifying liquid to complete the humidification of the oxygen. The humidified oxygen flows out of the humidification cup through the air outlet and flows to the user end through the nasal cannula. Because the oxygen humidification method in this application is changed from the traditional method of oxygen extending into the humidifying liquid to oxygen contacting the atomized humidifying liquid, the phenomenon of oxygen generating bubbles in the humidification cup is avoided, thus avoiding noise caused by bubble bursting. This reduces the noise of the humidification cup during operation and also avoids water splashing caused by bubble bursting, preventing the humidifying liquid from entering the air outlet and flowing to the user end. Furthermore, it reduces the loss of humidifying liquid, thereby reducing the frequency of replenishing the humidification cup and greatly improving the user experience.

[0012] Optionally, the separator is connected to a water-absorbing element, one end of which contacts the atomizing element, and the other end of which extends to the bottom of the liquid-containing cavity, so that the humidifying liquid in the liquid-containing cavity flows to the atomizing element under the action of the water-absorbing element.

[0013] By adopting the above technical solution, when the humidification cup in this application is working, the humidifying liquid contained in the liquid chamber flows to the atomizing element under the action of the water-absorbing element. Because the water-absorbing element contacts the atomizing element, the atomizing plate can then atomize the humidification chamber, ensuring the normal humidification of oxygen by the humidification cup. Since the humidifying liquid can flow to the atomizing plate under the action of the water-absorbing element, the position of the atomizing element can be raised, reducing the distance between the oxygen entering the humidification chamber through the air inlet and the atomized humidifying liquid. This allows more of the atomized humidifying liquid to come into contact with the oxygen, thereby improving the atomization effect on oxygen.

[0014] Optionally, the separator has an upwardly protruding mounting rib, the atomizing element includes an atomizing plate and a sealing ring sleeved on the atomizing plate, the sealing ring is disposed inside the mounting rib, and one end of the water-absorbing element is connected to the mounting rib.

[0015] By adopting the above technical solution, the upward protrusion of the mounting rib and the sealing ring located inside the mounting rib, along with the sealing ring fitted over the atomizing plate, elevate the position of the atomizing plate, thereby shortening the distance between the atomizing plate and the air inlet. This allows more of the atomized humidified liquid to come into contact with oxygen, improving the humidification effect and efficiency. Simultaneously, the sealing ring seals the gap between the atomizing plate and the mounting rib, ensuring a tight seal and preventing the humidified liquid from overflowing into this gap. This further prevents the humidified liquid from splashing into the air outlet, improving the user experience. Furthermore, the interference fit between the sealing ring and the mounting rib secures the atomizing plate, reducing the installation difficulty of the atomizing component and improving the assembly and maintenance efficiency of the humidification cup. Additionally, the connection of one end of the suction component to the mounting rib increases its stability, enabling it to stably deliver humidified liquid to the atomizing component.

[0016] Optionally, the separator includes a separator plate, the periphery of which includes a free section and a connecting section, the connecting section being sealed to the inner sidewall of the cup body, and a water inlet being formed between the free section and the inner sidewall of the cup body.

[0017] By adopting the above technical solution, a water inlet is formed between the free section and the internal side wall of the cup body, which reduces the difficulty of adding or replenishing the humidifying fluid to the liquid chamber, thereby improving the efficiency of adding or replenishing the humidifying fluid to the liquid chamber and further improving the user experience.

[0018] Optionally, the partition plate includes a first partition plate and a second partition plate connected together, the second partition plate extending upwardly from the first partition plate, the first partition plate dividing the accommodating cavity in the axial direction, and the second partition plate dividing the accommodating cavity in the radial direction, so that a water injection channel is formed between the second partition plate and the inner sidewall of the cup body.

[0019] By adopting the above technical solution, since the first partition plate partially divides the accommodating cavity axially, the humidification cavity is located above the first partition plate. This allows the center of gravity of the humidification cup containing the humidifying liquid to shift downwards, bringing the center of gravity closer to the bottom of the humidification cup and thus increasing its stability. Since the second partition plate partially divides the accommodating cavity radially, the humidification cavity is located on the side of the second partition plate. The second partition plate extends upwards from the first partition plate, allowing it to guide the oxygen flowing towards the outlet, increasing the smoothness of oxygen flow and ensuring the humidification cup's output efficiency. Furthermore, the arrangement of the first and second partition plates increases the volume of the humidification cavity to a certain extent, thereby improving the humidification efficiency of the humidification cup for oxygen.

[0020] Optionally, the second partition plate further includes a flow guiding area, which is recessed in the direction of the first partition plate.

[0021] By adopting the above technical solution, the guide area is recessed in the direction of the first partition plate, thereby increasing the opening area of ​​the water inlet, which further facilitates the user to add or replenish the humidifying liquid into the liquid chamber, thereby further improving the user experience.

[0022] Optionally, the liquid-containing cavity is provided with a guide tube, which forms a water injection hole communicating with the water injection port and a guide channel communicating with the water injection hole. A blocking float is provided in the guide channel. The blocking float can float in the guide channel with the liquid level of the humidifying liquid. When the humidifying liquid is at the maximum liquid level, the blocking float can block the water injection hole.

[0023] By adopting the above technical solution, when adding or replenishing humidifying liquid into the liquid chamber, the sealing float moves upward with the liquid level of the humidifying liquid. When the humidifying liquid is at its maximum level, the sealing float can block the water injection hole, thereby preventing the overflow of the liquid chamber due to a large amount of humidifying liquid added. This also prevents the humidifying liquid from being sprayed out through the air outlet, further improving the user experience.

[0024] Optionally, the liquid-containing cavity is provided with a support rib, the periphery of which is connected to the partition plate and the inner sidewall of the cup body to separate the liquid-containing cavity. The support rib has an opening, and the top end of the guide tube is connected to the support rib so that the opening communicates with the water injection hole.

[0025] By adopting the above technical solution, when adding or replenishing humidifying liquid into the liquid-containing chamber, the humidifying liquid enters the liquid-containing chamber through the water inlet, allowing it to flow through the opening and water inlet to the bottom of the support rib. As more and more humidifying liquid enters the bottom of the support rib, the bottom space of the support rib is filled with humidifying liquid. At this point, the humidifying liquid can no longer flow through the opening and water inlet to the bottom of the support rib. At this time, adding or replenishing humidifying liquid into the liquid-containing chamber can be stopped to avoid the phenomenon of excessive humidifying liquid adding or replenishing and easily overflowing from the filling port. This allows the support rib to serve as a reference for the user to add or replenish humidifying liquid, so that the user can grasp the amount of humidifying liquid to add. At the same time, it increases the cleanliness of the humidifying cup, thereby further improving the user experience.

[0026] Optionally, the bottom end of the guide tube abuts against the bottom wall of the cup body, and the bottom end of the guide tube has a connecting hole.

[0027] By adopting the above technical solution, since the bottom end of the guide tube abuts against the bottom wall of the cup body and the bottom end of the guide tube has a connecting hole, it is possible to support the separator while ensuring that the guide tube is connected to the liquid cavity, thereby increasing the stability of the separator and ensuring the separation effect of the separator on the accommodating cavity.

[0028] Optionally, the guide pipe includes a small-diameter section, a variable-diameter section, and a large-diameter section that are interconnected. One end of the small-diameter section forms the water injection hole, and the projected area of ​​the sealing float can cover the inner diameter area of ​​the small-diameter section.

[0029] By adopting the above technical solution, since the projected area of ​​the sealing float can cover the inner diameter area of ​​the small diameter section, the sealing float can block the water injection hole when the wetting liquid is at its maximum level. Furthermore, since a variable diameter section is provided, the variable diameter section can guide the sealing float, allowing it to move smoothly to the small diameter section under the guidance of the variable diameter section to block the water injection hole, thereby ensuring the sealing effect of the sealing float on the water injection hole.

[0030] Optionally, the cup lid is provided with an air guide tube communicating with the air inlet. An air outlet is provided at the bottom of the air guide tube. A filter and dispersion element is sleeved on the outside of the air guide tube. The filter and dispersion element is located at the air outlet so that the oxygen in the air guide tube enters the filter and dispersion element through the air outlet and enters the humidification chamber after being filtered and dispersed by the filter and dispersion element.

[0031] By adopting the above technical solution, since the cup lid is equipped with an air guide tube connected to the air inlet, the distance between the oxygen entering the humidification chamber through the air inlet and the atomizing plate is further shortened, so as to ensure the contact effect between the oxygen and the atomized humidifying liquid, thereby improving the humidification effect and humidification efficiency of the oxygen. Furthermore, an air outlet is provided at the bottom of the air guide tube, and the filter dispersion element is located at the air outlet. Then, the oxygen in the air guide tube enters the filter dispersion element through the air outlet, and enters the humidification chamber after being filtered and dispersed by the filter dispersion element, so that the oxygen enters the humidification chamber more dispersedly, thereby further improving the humidification effect and humidification efficiency of the oxygen. At the same time, it also achieves oxygen filtration, thereby improving the user's inhalation comfort, and thus further improving the user's user experience.

[0032] Optionally, the cup body is provided with conductive terminals exposed to the outside of the cup body, and the conductive terminals are electrically connected to the atomizing element.

[0033] By adopting the above technical solution, since the conductive terminals are exposed on the outside of the cup body and are electrically connected to the atomizing element, the difficulty of supplying power to the atomizing element is reduced, thereby simplifying the structural design of the humidification cup, reducing the production cost of the humidification cup, and also ensuring the stability of the power supply to the atomizing element to guarantee the stable operation of the humidification cup.

[0034] Optionally, the atomizing element has a wiring harness electrically connected to the conductive terminal, the separator is provided with a downwardly extending sealing rib, the sealing rib and the inner wall of the cup together form a waterproof channel, the wiring harness is disposed in the waterproof channel, and the sealing rib abuts against the bottom of the cup.

[0035] By adopting the above technical solution, since the sealing rib abuts against the bottom of the cup body, the sealing rib can support the separator, thereby increasing the stability of the separator and thus increasing the stability of the separator in separating the accommodating cavity; and the sealing rib and the inner wall of the cup body together form a waterproof channel, and the wiring harness is placed in the waterproof channel, thereby avoiding the phenomenon of short circuit of the atomizing plate caused by the wiring harness coming into contact with the humidifying liquid, thus ensuring the stable operation of the humidifying cup and greatly improving the safety of the humidifying cup.

[0036] This application also discloses an oxygen generator to reduce noise during operation and prevent humidification liquid from flowing to the user end, thereby improving the user experience.

[0037] An oxygen concentrator, comprising:

[0038] A host computer, the host computer having a mounting position;

[0039] A humidification cup having conductive terminals, the humidification cup being placed in the mounting position, and the mounting position being provided with a conductive member electrically connected to the conductive terminals, the humidification cup being selected from the humidification cups described above.

[0040] By adopting the above technical solution, since the oxygen concentrator in this application uses the aforementioned humidification cup, the noise generated during the operation of the oxygen concentrator is reduced, and the phenomenon of humidification liquid flowing to the user end is avoided, thereby improving the user experience. In addition, since the mounting position is provided with a conductive component that is electrically connected to the conductive terminal, the oxygen concentrator can supply power to the humidification cup, thereby simplifying the way the humidification cup is powered and reducing the production cost of the oxygen concentrator.

[0041] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0042] 1. The humidification cup of this application includes a cup body, a separator, a cup lid, and an atomizing component. The cup body has an internal cavity. The separator is located within the cavity and divides it into a liquid cavity for holding humidifying liquid and a humidification cavity for humidifying oxygen. The cup lid covers the cup body and has an air inlet and an air outlet, both of which are connected to the humidification cavity. The atomizing component is located within the separator and is used to atomize the humidifying liquid in the cavity. The atomized humidifying liquid enters the humidification cavity to humidify the oxygen entering the cavity. Because of this application… The humidification cup in this device changes the traditional method of humidifying oxygen by having it immerse itself in the humidifying liquid. Instead, the oxygen comes into contact with the atomized humidifying liquid, thus avoiding the formation of bubbles in the humidification cup and preventing noise caused by bubble bursts. This reduces the noise level during operation and also prevents water splashing from the humidifying liquid, thus preventing it from entering the air outlet and flowing to the user. Furthermore, it reduces the loss of humidifying liquid, decreasing the frequency of refilling the humidification cup and significantly improving the user experience.

[0043] 2. The separator in this application is connected to a water-absorbing element. One end of the water-absorbing element contacts the atomizing element, and the other end of the water-absorbing element extends to the bottom of the liquid-containing chamber. This allows the humidifying liquid in the liquid-containing chamber to flow to the atomizing element under the action of the water-absorbing element, thereby raising the position of the atomizing element. This reduces the distance between the oxygen entering the humidifying chamber through the air inlet and the atomized humidifying liquid, allowing more of the atomized humidifying liquid to come into contact with the oxygen, thus improving the atomization effect of the oxygen.

[0044] 3. The separator in this application has an upwardly protruding mounting rib. The atomizing component includes an atomizing plate and a sealing ring fitted onto the atomizing plate. The sealing ring is located inside the mounting rib. One end of the water-absorbing component is connected to the mounting rib, thereby raising the position of the atomizing plate to shorten the distance between the atomizing plate and the air inlet. This allows more of the atomized humidified liquid to come into contact with oxygen, improving the humidification effect and efficiency of oxygen. Simultaneously, the sealing ring also seals the gap between the atomizing plate and the mounting rib, ensuring a tight seal between them. This design prevents the humidifying liquid from overflowing into the gap between the atomizing plate and the mounting rib, thus further preventing humidifying liquid from splashing into the air outlet and improving the user experience. Furthermore, the interference fit between the sealing ring and the mounting rib secures the atomizing plate, reducing the difficulty of installing the atomizing component and improving the assembly and maintenance efficiency of the humidifying cup. Additionally, since one end of the suction component is connected to the mounting rib, its stability is increased, ensuring a stable supply of humidifying liquid to the atomizing component.

[0056] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0057] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0058] Furthermore, it should be understood in the description of this application that the terms "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0059] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0060] In this application, unless otherwise expressly specified and limited, the "above" or "below" of the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. In the description of this specification, references to terms such as "implementation," "example," "a particular embodiment," "example," or "specific example," etc., indicate that the specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0061] Reference Figures 1 to 8 A humidification cup for an oxygen generator is disclosed, comprising a cup body 1, a separator 2, a cup lid 3, and an atomizing element 4. The cup body 1 has an internal cavity. The separator 2 is disposed in the cavity and divides the cavity into a liquid cavity 11 for holding humidifying liquid and a humidification cavity 12 for humidifying oxygen. The cup lid 3 is disposed on the cup body 1 and has an air inlet 31 and an air outlet 32, both of which are connected to the humidification cavity 12. The atomizing element 4 is disposed in the separator 2 and is used to atomize the humidifying liquid in the liquid cavity 11. The atomized humidifying liquid enters the humidification cavity 12 to humidify the oxygen entering the humidification cavity 12.

[0062] When the humidification cup in this application is working, the atomizing component 4 atomizes the humidification liquid contained in the liquid chamber 11 so that the atomized humidification liquid enters the humidification chamber 12. Oxygen enters the humidification chamber 12 through the air inlet 31 and comes into contact with the atomized humidification liquid to complete the humidification of the oxygen. The humidified oxygen flows out of the humidification cup through the air outlet 32 ​​and flows to the user end through the nasal oxygen tube.

[0063] Because the humidification method of the humidification cup in this application changes from the traditional method of oxygen immersing in the humidification liquid to oxygen contacting the atomized humidification liquid, the phenomenon of oxygen generating bubbles in the humidification cup is avoided, thus preventing noise caused by bubble bursting. This reduces the noise of the humidification cup during operation and also avoids water splashing caused by bubble bursting, preventing the humidification liquid from entering the air outlet 32 ​​and flowing to the user end. Furthermore, it reduces the loss of humidification liquid, thereby reducing the frequency of needing to replenish the humidification liquid in the humidification cup, and thus greatly improving the user experience.

[0064] In a preferred embodiment, refer to Figure 3 , Figure 4 , Figure 5 and Figure 7The separator 2 is connected to a water-absorbing component 111. One end of the water-absorbing component 111 contacts the atomizing component 4, and the other end of the water-absorbing component 111 extends to the bottom of the liquid-containing cavity 11, so that the humidifying liquid in the liquid-containing cavity 11 flows to the atomizing component 4 under the action of the water-absorbing component 111.

[0065] When the humidification cup in this application is working, the humidification liquid contained in the liquid chamber 11 flows to the atomizing element 4 under the action of the water absorption element 111. Since the water absorption element 111 contacts the atomizing element 4, the atomizing plate 41 can atomize the humidification chamber 12 to ensure the normal humidification of oxygen by the humidification cup.

[0066] Since one end of the water-absorbing component 111 contacts the atomizing component 4 and the other end of the water-absorbing component 111 extends to the bottom of the liquid-containing chamber 11, the position of the atomizing component 4 can be raised to reduce the distance between the oxygen entering the humidification chamber 12 through the air inlet 31 and the atomized humidifying liquid, thereby allowing more atomized humidifying liquid to come into contact with oxygen and improve the atomization effect of oxygen.

[0067] Furthermore, the water-absorbing component 111 enables the water-absorbing component 111 to transport the humidifying liquid in the liquid-containing chamber 11 to the atomizing component 4, so that the atomizing component 4 atomizes the humidifying liquid.

[0068] This application does not specifically limit the structure of the absorbent component 111. Preferably, the absorbent component 111 is an absorbent cotton strip with one end in contact with the atomizing component 4, so as to deliver the humidifying liquid to the atomizing plate 41; at the same time, compared with the solution where the absorbent component 111 is a water pump, the energy consumption of the humidification cup is reduced. In other embodiments, the absorbent component 111 can also be an absorbent rope with one end in contact with the atomizing component 4, or other structures that can deliver the humidifying liquid upward.

[0069] This application does not specify the structure of the atomizing element 4 or the installation method of the atomizing element 4. Preferably, refer to Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The separator 2 has an upwardly protruding mounting rib 211, the atomizing component 4 includes an atomizing plate 41 and a sealing ring 42 sleeved on the atomizing plate 41, the sealing ring 42 is located inside the mounting rib 211, and one end of the water-absorbing component 111 is connected to the mounting rib 211.

[0070] Specifically, the mounting rib 211 has a through hole that passes through the separator 2 in the vertical direction. The through hole is a stepped hole. The end with a larger diameter of the through hole is located at the end of the separator 2 facing the cup lid 3, and the end with a smaller diameter of the through hole is located at the end of the separator 2 facing the bottom of the cup body 1. The sealing ring 42 is installed at the end of the through hole facing the cup lid 3, and the outer peripheral surface of the sealing ring 42 is press-fitted with the hole wall of the through hole. The water-absorbing component 111 extends into the through hole near the bottom of the cup body 1 and abuts against the atomizing plate 41.

[0071] Because the mounting rib 211 protrudes upwards, the sealing ring 42 is located inside the mounting rib 211 and is fitted onto the atomizing plate 41. This raises the position of the atomizing plate 41, shortening the distance between the atomizing plate 41 and the air inlet 31. This allows more of the atomized humidifying liquid to come into contact with oxygen, improving the humidification effect and efficiency. Simultaneously, the sealing ring 42 seals the gap between the atomizing plate 41 and the mounting rib 211, ensuring a tight seal and preventing humidifying liquid from entering the atomizing plate 41. The gap between the mounting ribs 211 prevents overflow, thus further preventing the humidifying liquid from splashing into the air outlet 32, thereby improving the user experience. The sealing ring 42 and the mounting ribs 211 are also used to fix the atomizing plate 41, reducing the installation difficulty of the atomizing component 4 and improving the assembly and maintenance efficiency of the humidifying cup. Since one end of the water suction component 111 is connected to the mounting ribs 211, the stability of the water suction component 111 is increased, so that the water suction component 111 can stably deliver the humidifying liquid to the atomizing component 4.

[0072] In other embodiments, the atomizing element 4 may also be an atomizing nozzle or other structures capable of atomizing the humidifying liquid.

[0073] In other embodiments, the atomizing element 4 can also be fixedly connected to the separator 2 by fasteners or snap-fit ​​structures.

[0074] This application does not specify a particular method for adding the humidifying fluid; preferably, refer to [the following method is used]. Figure 6 , Figure 7 and Figure 8 The separator 2 includes a separator plate, the periphery of which includes a free section and a connecting section. The connecting section is sealed to the inner sidewall of the cup body 1, and a water inlet 222 is formed between the free section and the inner sidewall of the cup body 1.

[0075] Specifically, the free section is located at the top of the partition plate so that the water inlet 222 is located at the top opening of the cup body 1, thereby avoiding the phenomenon that the humidifying liquid may enter the humidifying chamber 12 when adding or replenishing the humidifying liquid to the liquid-containing chamber 11. This reduces the difficulty of adding or replenishing the humidifying liquid to the liquid-containing chamber 11, improves the efficiency of adding or replenishing the humidifying liquid to the liquid-containing chamber 11, and further improves the user experience.

[0076] It should be noted that the sealing connection in this application can be achieved by a sealing strip, or by using heat fusion technology to fix the two together.

[0077] The better one is to refer to Figure 4 and Figure 5 The free section is equipped with a sealing strip. After the cup lid 3 is placed on the cup body 1, the sealing strip contacts the inner wall of the cup body 1 and deforms to completely isolate the liquid chamber 11 from the humidification chamber 12, so as to further prevent the humidification liquid from entering the air outlet 32, thereby further improving the user experience.

[0078] This application does not specifically limit the structure of the partition plate; preferably, refer to... Figure 7 and Figure 8 The partition includes a first partition 21 and a second partition 22 connected together. The second partition 22 extends upward from the first partition 21. The first partition 21 divides the accommodating cavity in the radial direction, and the second partition 22 divides the accommodating cavity in the axial direction, so that a water injection channel is formed between the second partition 22 and the inner sidewall of the cup body 1.

[0079] Because the first partition plate 21 axially divides the accommodating cavity, the humidification chamber 12 is located above the first partition plate 21. This allows the center of gravity of the humidification cup containing the humidifying liquid to shift downwards, bringing the center of gravity closer to the bottom of the humidification cup and increasing its stability. Because the second partition plate 22 radially divides the accommodating cavity, the humidification chamber 12 is located on the side of the second partition plate 22. The second partition plate 22 extends upwards from the first partition plate 21, guiding the oxygen flowing towards the outlet 32 ​​and increasing the smoothness of oxygen flow towards the outlet 32, thus ensuring the humidification cup's output efficiency. Furthermore, the arrangement of the first partition plate 21 and the second partition plate 22 increases the volume of the humidification chamber 12 to a certain extent, thereby improving the humidification efficiency of the humidification cup for oxygen.

[0080] The better one is to refer to Figure 7 and Figure 8 The mounting rib 211 is installed on the first partition plate 21, and the air inlet 31 is positioned opposite to the first partition plate 21 to further improve the humidification effect of oxygen.

[0081] Furthermore, refer to Figure 4 and Figure 5 The inner wall of the cup body 1 is provided with a positioning rib 14 located at the bottom of the first partition plate 21. The positioning rib 14 abuts against the bottom of the first partition plate 21 to support the first partition plate 21 and increase the stability of the partition 2.

[0082] Furthermore, refer to Figure 7 and Figure 8 The second partition plate 22 also includes a flow guiding area 221, which is recessed in the direction of the first partition plate 21.

[0083] Specifically, the guide zone 221 is located at the end of the second partition plate 22 away from the first partition plate 21, thereby increasing the opening area of ​​the water inlet 222, so as to further facilitate the user to add or replenish the humidifying liquid into the liquid chamber 11, thereby further improving the user's experience.

[0084] In other embodiments, the partition plate is a plate-like structure that extends vertically or obliquely along the axial direction of the cup body 1. In this case, the humidification chamber 12 is located on the side of the liquid-containing chamber 11, and a water inlet 222 is formed between the top of the partition plate and the inner wall of the cup body 1. Alternatively, the partition plate can also be a plate-like structure that extends horizontally or obliquely along the radial direction of the cup body 1. In this case, the humidification chamber 12 is located above the liquid-containing chamber 11, and the partition plate is provided with a perforated structure for the user to add humidifying liquid. Furthermore, when the partition plate is provided to extend vertically or obliquely along the axial direction of the cup body 1, the atomizing element 4 can be located at the bottom of the partition plate, thereby eliminating the need for the water-absorbing element 111 and reducing the production cost of the humidification cup.

[0085] In a preferred embodiment, refer to Figure 3 , Figure 4 , Figure 5 Figure 7 and Figure 8 The liquid-containing chamber 11 is provided with a guide pipe 112, which forms a water injection hole 114 communicating with the water injection port 222 and a guide channel communicating with the water injection hole 114. A blocking float 113 is provided in the guide channel. The blocking float 113 can float in the guide channel with the liquid level of the humidifying liquid. When the humidifying liquid is at the maximum liquid level, the blocking float 113 can block the water injection hole 114.

[0086] When adding or replenishing humidifying fluid to the liquid chamber 11, the sealing float 113 moves upward with the liquid level of the humidifying fluid. When the humidifying fluid is at its maximum level, the sealing float 113 blocks the water injection hole 114, thereby preventing the humidifying fluid from overflowing the liquid chamber 11 due to a large amount of humidifying fluid being added. This also prevents the humidifying fluid from being sprayed out through the air outlet 32, further improving the user experience.

[0087] Furthermore, refer to Figure 3 and Figure 8 The liquid-containing cavity 11 is provided with a support rib 117. The periphery of the support rib 117 is connected to the partition plate and the inner side wall of the cup body 1 to separate the liquid-containing cavity 11. The support rib 117 has an opening. The top end of the guide tube 112 is connected to the support rib 117 so that the opening communicates with the water injection hole 114.

[0088] Specifically, the support rib 117 is connected to the second partition plate 22 and located above the first partition plate 21 to increase the volume of the liquid-containing cavity 11 that can effectively contain the humidifying liquid, thereby further reducing the frequency of replenishing the humidifying liquid in the humidifying cup and further improving the user experience.

[0089] When adding or replenishing humidifying fluid to the liquid-containing chamber 11, the humidifying fluid enters the chamber 11 through the water inlet 222, allowing it to flow through the opening and water inlet 114 to the bottom of the support rib 117. As more and more humidifying fluid enters the bottom of the support rib 117, the bottom space of the support rib 117 becomes full. At this point, the humidifying fluid can no longer flow through the opening and water inlet 114 to the bottom of the support rib 117. Adding or replenishing humidifying fluid to the liquid-containing chamber 11 at this time can be stopped to avoid excessive addition or replenishment, which could easily overflow from the filling port. This allows the support rib 117 to serve as a reference for the user when adding or replenishing humidifying fluid, enabling the user to control the amount of humidifying fluid added. It also increases the cleanliness of the humidifying cup, further improving the user experience. In addition, the support rib 117 also provides side support for the partition plate, further increasing the stability of the partition 2.

[0090] Furthermore, refer to Figure 4 and Figure 5 The bottom end of the guide tube 112 abuts against the bottom wall of the cup body 1, and the bottom end of the guide tube 112 has a connecting hole 115. Thus, under the premise of ensuring that the guide tube 112 is connected to the liquid cavity 11, the guide tube 112 can support the separator 2, thereby increasing the stability of the separator 2 and ensuring the separation effect of the separator 2 on the accommodating cavity.

[0091] This application does not specifically limit the structure of the guide tube 112. Preferably, the guide tube 112 includes a small diameter section, a variable diameter section and a large diameter section that are interconnected. One end of the small diameter section forms a water injection hole 114. The projected area of ​​the sealing float 113 can cover the inner diameter area of ​​the small diameter section, so that when the humidifying liquid is at the maximum liquid level, the sealing float 113 can seal the water injection hole 114.

[0092] Specifically, the variable diameter section is located between the small diameter section and the large diameter section, and the small diameter section is connected to the support bar 117.

[0093] Because of the variable diameter section, the variable diameter section can guide the sealing float 113, so that the sealing float 113 can move smoothly to the small diameter section under the guidance of the variable diameter section to seal the water injection hole 114, thereby ensuring the sealing effect of the sealing float 113 on the water injection hole 114.

[0094] This application does not specifically limit the structure of the sealing float 113. Preferably, the sealing float 113 has a spherical structure, and the diameter of the sealing float 113 is smaller than the inner diameter of the large-diameter section and larger than the inner diameter of the small-diameter section, so as to ensure that the sealing float 113 can seal the water injection, and that the wetting liquid can flow through the gap between the sealing float 113 and the large-diameter section to the bottom of the sealing float 113. In other embodiments, the sealing float 113 can also be a block structure with a hemispherical top.

[0095] This application does not specify the formation method of the variable diameter section; preferably, refer to... Figure 4 The inner wall of the larger diameter section near the smaller diameter section is provided with guide ribs 116. At least three guide ribs 116 are spaced apart along the circumference of the sealing float 113. The width of each guide rib 116 gradually decreases towards the smaller diameter section, allowing the guide ribs 116 to guide the sealing float 113. In other words, the guide ribs 116 and the larger diameter section near the smaller diameter section together form a variable diameter section, thereby reducing the weight of the guide tube 112 and the humidification cup, achieving the effect of lightweight design for the humidification cup. In other embodiments, the variable diameter section can also be formed by the wall thickness of the guide tube 112 gradually increasing from the larger diameter section to the smaller diameter section.

[0096] In a preferred embodiment, refer to Figure 3 , Figure 4 and Figure 5 The cup lid 3 is provided with an air guide pipe 34 that is connected to the air inlet 31. An air outlet is provided at the bottom of the air guide pipe 34. A filter and dispersion element 341 is sleeved on the outside of the air guide pipe 34. The filter and dispersion element 341 is located at the air outlet so that the oxygen in the air guide pipe 34 enters the filter and dispersion element 341 through the air outlet and enters the humidification chamber 12 after being filtered and dispersed by the filter and dispersion element 341.

[0097] Because the cup lid 3 is equipped with an air guide tube 34 that communicates with the air inlet 31, the distance between the oxygen entering the humidification chamber 12 through the air inlet 31 and the atomizing plate 41 is further shortened, so as to ensure the contact effect between the oxygen and the atomized humidifying liquid, thereby improving the humidification effect and humidification efficiency of the oxygen; and the bottom of the air guide tube 34 is provided with an air outlet, and the filter dispersion element 341 is located at the air outlet. Then, the oxygen in the air guide tube 34 enters the filter dispersion element 341 through the air outlet, and enters the humidification chamber 12 after being filtered and dispersed by the filter dispersion element 341, so that the oxygen enters the humidification chamber 12 more dispersedly, thereby further improving the humidification effect and humidification efficiency of the oxygen, while also filtering the oxygen to improve the user's inhalation comfort, thereby further improving the user's user experience.

[0098] This application does not specifically limit the structure of the filter dispersion element 341. Preferably, the filter dispersion element 341 is filter cotton to improve the dispersion and filtration effect of oxygen, and at the same time, it can also avoid the phenomenon of noise generated when oxygen passes through the filter dispersion element 341, thereby further reducing the noise when the humidification cup is working. In other embodiments, the filter dispersion element 341 can also be a ring-shaped cotton wadding or other porous structures fitted outside the air guide tube 34.

[0099] This application does not specify a particular power supply method for the humidification cup; preferably, refer to... Figure 1 and Figure 3 The cup body 1 is provided with conductive terminals 13 exposed to the outside of the cup body 1. The conductive terminals 13 are electrically connected to the atomizing element 4, thereby reducing the difficulty of supplying power to the atomizing element 4, simplifying the structural design of the humidification cup, reducing the production cost of the humidification cup, and increasing the stability of power supply to the atomizing element 4 to ensure the stable operation of the humidification cup.

[0100] Furthermore, refer to Figure 3 , Figure 4 , Figure 5 and Figure 7 The atomizing component 4 has a wire harness 411 electrically connected to the conductive terminal 13. The separator 2 is provided with a downwardly extending sealing rib 212. The sealing rib 212 and the inner wall of the cup body 1 together form a waterproof channel. The wire harness 411 is located in the waterproof channel, and the sealing rib 212 abuts against the bottom of the cup body 1.

[0101] Specifically, the sealing rib 212 has a C-shaped cross-section, and the opening of the sealing rib 212 faces the inner wall of the cup body 1, so that the sealing rib 212 and the inner wall of the cup body 1 together form a waterproof channel.

[0102] Since the sealing rib 212 abuts against the bottom of the cup body 1, it can support the separator 2, thereby increasing the stability of the separator 2 and thus increasing the stability of the separator 2 in separating the accommodating cavity. Furthermore, the sealing rib 212 and the inner wall of the cup body 1 together form a waterproof channel, and the wiring harness 411 is located in the waterproof channel, thereby preventing the wiring harness 411 from coming into contact with the humidifying liquid and causing a short circuit in the atomizing plate 41. This ensures the stable operation of the humidifying cup and greatly improves the safety of the humidifying cup.

[0103] The better one is to refer to Figure 1 and Figure 3 The conductive terminal 13 is located at the bottom edge of the cup body 1, which allows the humidification cup to apply downward pressure to the conductive terminal 13 under its own weight and the gravity of the humidification liquid, so as to ensure the electrical conductivity stability between the conductive terminal 13 and the conductive component located on the oxygen generator.

[0104] In other embodiments, the wiring harness 411 connecting the atomizing element 4 can extend out of the humidification chamber 12 via the cup lid 3 or the cup body 1, so as to use the electrical connection between the wiring harness 411 and the power source to provide power to the atomizing element 4.

[0105] In a preferred embodiment, refer to Figure 1 and Figure 2 The cup lid 3 also has a pressure relief valve 33, which is connected to the humidification chamber 12 to keep the pressure inside the humidification chamber 12 below a set pressure, thereby increasing the safety of the humidification cup.

[0106] This application does not specify the connection method between the cup lid 3 and the cup body 1. Preferably, refer to... Figure 4 and Figure 5 The cup lid 3 is provided with an internal thread, and the top of the cup body 1 is provided with an external thread that matches the internal thread. This adaptation of the internal and external threads enables a threaded connection between the cup lid 3 and the cup body 1, thereby increasing the connection stability between them. In other embodiments, the cup lid 3 has a sealing ring that extends into the interior of the cup body 1. A sealing structure is fitted around the sealing ring, extending into the interior of the cup body 1. This sealing structure, through an interference fit with the inner wall of the cup body 1, enables the connection between the cup lid 3 and the cup body 1.

[0107] This application also discloses an oxygen generator, which includes a main unit and a humidification cup. The main unit has a mounting position, and the humidification cup has a conductive terminal 13. The humidification cup is placed in the mounting position, and the mounting position is provided with a conductive member that is electrically connected to the conductive terminal 13. The humidification cup is selected from the above-mentioned humidification cup.

[0108] Because the oxygen concentrator in this application uses the aforementioned humidification cup, the noise generated during operation is reduced, and the phenomenon of humidification liquid flowing to the user end is avoided, thereby improving the user experience. In addition, since the mounting position is provided with a conductive component that is electrically connected to the conductive terminal 13, the oxygen concentrator can supply power to the humidification cup, simplifying the way the humidification cup is powered and thus reducing the production cost of the oxygen concentrator.

[0109] For any parts not mentioned in this application, existing technologies may be used or referenced.

[0110] 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.

[0111] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
