Description

Technical Field

[0001] This application relates to the field of oxygen concentrator technology, for example to a humidification cup for an oxygen concentrator and an oxygen concentrator. Background Technology

[0002] Currently, an oxygen concentrator is a device that produces oxygen using air separation technology or a chemical reaction. A humidification cup for an oxygen concentrator is an important auxiliary device used in conjunction with the concentrator. The oxygen produced by an oxygen concentrator is usually quite dry, and direct inhalation can irritate the respiratory mucosa, leading to discomfort such as dry mouth and nose, and sore throat. A humidification cup can humidify the dry oxygen with water, making it more moist and gentle, reducing irritation to the respiratory tract and improving the comfort of oxygen inhalation. However, existing humidification cups are molded in one piece, with an air inlet, air outlet, and water inlet on the cup body. Cleaning the inside of the cup is relatively difficult, and there is a significant risk of bacterial growth over prolonged use.

[0003] One related technology includes a humidifying cup comprising a cup body and a cup lid. The cup lid is detachably mounted on the top of the cup body and has an air inlet, an air outlet, and a water inlet. An air inlet tube extends into the cup body through the air inlet. The cup lid can be removed from the top of the cup body, facilitating cleaning of both the lid and the cup body and reducing the risk of bacterial growth during prolonged use.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] The air inlet of the cup lid needs to be plugged into the oxygen concentrator. Because the air inlet is located high up, users need to squat down to plug the humidification cup upwards into the oxygen concentrator, resulting in a poor user experience.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below.

[0014] Optionally, a U-shaped tube is provided on one side of the cup body, with one end of the U-shaped tube connected to the air inlet.

[0015] Optionally, the height of the end of the U-shaped tube that connects to the air inlet is lower than that of the other end.

[0016] Optionally, the cup body and / or lid may be made of a transparent material.

[0017] Optionally, the cup body includes a cup base and a cup barrel. The bottom of the cup base has an air inlet; the bottom of the cup barrel is detachably connected to the cup base, and the cup lid is placed on top of the cup barrel.

[0018] In some embodiments, an oxygen concentrator includes a humidification cup for an oxygen concentrator as described in the above embodiments.

[0019] The humidification cup and oxygen concentrator for an oxygen concentrator provided in this disclosure can achieve the following technical effects:

[0020] Add an appropriate amount of water to the cup, then place the lid on top. The air inlet has a breathable rubber vent to prevent water from flowing out.

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0039] Combination Figure 1-2 As shown, this embodiment of the present disclosure provides a humidification cup for an oxygen concentrator, comprising: a cup body 100, a breathable rubber 200, and a cup lid 300. The bottom of the cup body 100 is provided with an air inlet 101; the breathable rubber 200 is disposed inside the air inlet 101; the cup lid 300 is disposed on the top of the cup body 100, and the cup lid 300 is provided with an air outlet 301.

[0040] Using the humidification cup for an oxygen concentrator provided in this embodiment, an appropriate amount of water is added to the cup body 100, and then the cup lid 300 is placed on the cup body 100. The air inlet 101 is equipped with a breathable rubber 200 to prevent water in the cup body 100 from flowing downwards through the air inlet 101. Since the air inlet 101 is located at the bottom of the cup body 100, the position of the oxygen concentrator's air outlet 301 can be more clearly observed when the cup body 100 is inserted into the oxygen concentrator. The user can insert the cup body 100 into the oxygen concentrator without having to squat down, making operation more convenient and improving the user experience. Furthermore, gas can enter the cup body 100 through the breathable rubber 200, and the gas in the cup body 100 then passes through the water in the cup body 100 and is discharged through the air outlet 301.

[0041] Understandably, the lid 300 can be removed from the cup body 100 to facilitate cleaning of both the cup body 100 and the lid 300, and also to facilitate adding water to the cup body 100.

[0042] Understandably, breathable rubber 200 is a type of rubber material with a one-way breathable structure, such as a rubber sheet with tiny pores. The diameter of the pores is smaller than that of a water molecule, and the diameter of the pores allows gas to pass through.

[0043] Optionally, the outer wall of the cup body 100 is provided with graduation lines. This allows the volume of water in the cup body 100 to be determined by the graduation lines. If the water level in the cup body 100 is low, the lid 300 can be opened to add water. Alternatively, if the water level in the cup body 100 is high, the lid 300 can be opened to pour the water out.

[0044] Optionally, the cup body 100 and the cup lid 300 have the same diameter. In this way, when the cup lid 300 is placed on the cup body 100, the outer wall of the cup body 100 is relatively flush with the outer wall of the cup lid 300, resulting in better overall integrity.

[0045] Optionally, the height of the cup body 100 can be greater than or equal to six times the height of the cup lid 300, and less than or equal to ten times the height of the cup lid 300. When the height of the cup body 100 is less than six times the height of the cup lid 300, the cup body 100 is relatively short, and the amount of water it can hold is relatively small. This requires more frequent refilling, resulting in a poor user experience. When the height of the cup body 100 is greater than ten times the height of the cup lid 300, the cup body 100 is relatively long, resulting in greater weight and space occupation, making it inconvenient for users to move and place the cup body 100. Therefore, a height range of six times or more and less than ten times the height of the cup lid 300 is more reasonable, reducing the frequency of refilling the cup body 100, making it easier to move and place the cup body 100, and resulting in a better user experience.

[0046] Specifically, the height of the cup body (100) is ten times the height of the cup lid (300).

[0047] Specifically, the cross-section of the cup body 100 is circular. In this way, the shape of the cup body 100 is relatively regular and its overall integrity is relatively good.

[0048] Specifically, the projection of the lid 300 onto the cup body 100 is circular. In this way, the shape of the lid 300 is relatively regular and corresponds to the shape of the cup body 100. When the cup body 100 and the lid 300 are closed together, the overall integrity is relatively good.

[0049] Specifically, the axis of the cup body 100 coincides with the axis of the cup lid 300.

[0050] Combination Figure 3 As shown, optionally, a vent spout 310 is provided in the center of the top of the cup lid 300, and a vent 301 is provided on the vent spout 310. In this way, the vent spout 310 is located at the top of the cup lid 300, which makes it convenient for users to connect pipes, and the disassembly and assembly are relatively convenient, resulting in a better user experience.

[0051] Optionally, the axis of the vent 310 coincides with the axis of the cup body 100. In this way, the vent 301 on the vent 310 corresponds to the axis of the cup body 100, so that the vent 301 is located at the top center of the cup body 100, which facilitates the discharge of gas from the vent 301.

[0052] Optionally, the vent spout 310 and the cup lid 300 are integrally formed. In this way, the connection between the vent spout 310 and the cup lid 300 is relatively strong and has relatively good durability.

[0053] Optionally, the diameter of the cup lid 300 can be greater than or equal to ten times the diameter of the air outlet 301, and less than or equal to fifteen times the diameter of the air outlet 301. When the diameter of the cup lid 300 is less than ten times the diameter of the air outlet 301, the diameter of the air outlet 301 is too large, resulting in an excessively high airflow rate and placing higher demands on the oxygen concentrator's oxygen production capacity. When the diameter of the cup lid 300 is more than fifteen times the diameter of the air outlet 301, the diameter of the air outlet 301 is too small, resulting in an insufficient airflow rate and a poor user experience. Therefore, a diameter range of ten times or more and fifteen times or less than fifteen times the diameter of the air outlet 301 is more reasonable, providing a moderate airflow rate, relatively lower demands on the oxygen concentrator's oxygen production capacity, and a relatively high oxygen flow rate, resulting in a better user experience.

[0054] Specifically, the diameter of the cup lid 300 is twelve times the diameter of the vent 301.

[0055] Optionally, the top center of the cup lid 300 has a recessed portion 320, and the vent spout 310 is disposed on the recessed portion 320. In this way, the recessed portion 320 is recessed towards the cup body 100, and the vent spout 310 is disposed on the recessed portion 320, reducing the risk of the vent spout 310 protruding from the cup lid 300, making it easier to place the cup lid 300 on a table or the ground after removal, and reducing the risk of the vent spout 310 directly contacting the ground or table, which is more hygienic.

[0056] Optionally, the concave portion 320 gradually narrows towards the cup body 100, while the vent spout 310 gradually narrows away from the cup body 100. This results in a relatively wide top for the concave portion 320 and a relatively narrow top for the vent spout 310, creating a relatively large gap between them and providing ample space for the user to insert the pipe into the vent spout 310. The narrow top and wide bottom of the vent spout 310 also facilitates gas flow.

[0057] Optionally, the tip of the vent 310 is retracted into or flush with the upper surface of the lid 300. This reduces the risk of the vent 310 directly contacting the lid after removal and placing it on a table or floor, thus improving hygiene. When the tip of the vent 310 is flush with the upper surface of the lid 300, the lid 300 will not protrude from the lid, reducing the risk of scratches or damage.

[0058] Combination Figure 4 As shown, optionally, a U-shaped tube 400 is provided on one side of the cup body 100, and one end of the U-shaped tube 400 is connected to the air inlet 101. In this way, since the air inlet 101 is located at the bottom of the cup body 100, when water in the cup body 100 flows out of the air inlet 101, the water flows directly into the U-shaped tube 400, and the U-shaped tube 400 intercepts and blocks the leaking water, reducing the risk of water flowing directly back into the oxygen concentrator.

[0059] Understandably, one end of the U-shaped tube 400 is connected to the cup body 100, and the other end of the U-shaped tube 400 can be directly connected to the oxygen concentrator. The U-shaped tube 400 is relatively small in size, which minimizes obstruction of the user's view and makes it easy to connect to the oxygen concentrator. The U-shaped tube 400 can also be connected to the oxygen concentrator through an additional pipe.

[0060] Optionally, the height of the end of the U-shaped tube 400 connected to the air inlet 101 is lower than the height of the other end. This means that the end of the U-shaped tube 400 connected to the air inlet 101 is relatively low, and the other end is relatively high. This makes the water level inside the cup 100 lower than the height of the other end of the U-shaped tube 400, thus reducing the risk of water overflowing from the U-shaped tube 400 in the event of water leakage from the cup 100.

[0061] Optionally, the horizontal distance between the two ends of the U-shaped tube 400 is greater than the diameter of the cup body 100. In this way, the distance between the non-connecting end of the U-shaped tube 400 and the cup body 100 is relatively large, reducing the risk of friction and collision between the U-shaped tube 400 and the cup body 100, and improving durability.

[0062] Optionally, the cup body 100 and / or the lid 300 may be made of a transparent material. This allows the user to directly view the remaining water level through the cup body 100, enabling them to add water promptly when the level is low, and also to quickly identify and remove any foreign objects from the cup body 100. Similarly, if the lid 300 is made of a transparent material, the user can directly view the remaining water level through it, allowing them to add water promptly when the level is low. Furthermore, if both the cup body 100 and the lid 300 are made of transparent materials, the user can directly view the remaining water level through both materials, enabling them to add water promptly when the level is low, and also to quickly identify and remove any foreign objects from the cup body 100.

[0063] Optionally, the cup body 100 and / or the cup lid 300 are made of PS (polystyrene) material. Thus, the cup body 100 made of PS has good optical properties, high light transmittance, and is relatively lightweight. The cup lid 300 made of PS also has good optical properties, high light transmittance, and is relatively lightweight.

[0064] Understandably, the cup body 100 and / or the lid 300 may also be made of other transparent materials, such as glass.

[0065] Optionally, the U-tube 400 is made of a transparent material. This allows the user to see the contents of the U-tube 400 more clearly, enabling them to promptly detect and address any water or foreign objects present in the U-tube 400.

[0066] Understandably, transparent materials include common materials such as glass or plastic.

[0067] Combination Figure 5 and Figure 6 As shown, optionally, the cup body 100 includes a cup base 110 and a cup cylinder 120. The cup base 110 has an air inlet 101 at its bottom; the bottom of the cup cylinder 120 is detachably connected to the cup base 110, and a cup lid 300 is placed on top of the cup cylinder 120. In this way, since humidifying cups are usually quite long and narrow, cleaning the inside of the humidifying cup is inconvenient and requires cleaning tools. However, the cup cylinder 120 can be detached from the cup base 110, allowing for separate cleaning of both the cup cylinder 120 and the cup base 110, making cleaning more convenient and reducing reliance on cleaning tools.

[0068] Optionally, the diameter of the air inlet 101 is larger than the diameter of the air outlet 301. This way, because the breathable rubber 200 is housed within the air inlet 101, the amount of gas passing through the breathable rubber 200 is relatively small. Since the diameter of the air inlet 101 is larger than the diameter of the air outlet 301, the relatively larger diameter of the air inlet 101 allows for the placement of a larger area of ​​the breathable rubber 200, increasing the area of ​​the breathable rubber 200 and thus increasing its air permeability.

[0069] Optionally, the bottom of the cup body 100 is provided with an air inlet 130, an air inlet 101 is provided on the air inlet 130, and a breathable rubber 200 is provided inside the air inlet 130. In this way, the air inlet 130 protrudes from the bottom of the cup body 100, making it easy for the air inlet 130 to be plugged into the oxygen concentrator.

[0070] Optionally, the diameter of the air inlet 101 is larger than the diameter of the U-shaped tube 400. This results in a higher flow rate at the air inlet 101 compared to the U-shaped tube 400. Since the air inlet 101 contains a breathable rubber 200, the amount of gas passing through the breathable rubber 200 is relatively small, while the flow rate at the air inlet 101 is relatively large. This allows for a larger diameter of the air inlet 101, enabling the placement of a larger breathable rubber 200, increasing its surface area and thus its air permeability.

[0071] Optionally, the U-shaped tube 400 is connected to the air inlet 130 so that the U-shaped tube 400 is connected to the air inlet 101. In this way, the air inlet 130 protrudes from the bottom of the cup body 100, and the connection between the U-shaped tube 400 and the air inlet 130 is more convenient, resulting in a relatively better user experience.

[0072] Optionally, the U-shaped tube 400 is connected to the air inlet 130. In this way, the U-shaped tube 400 and the air inlet 130 can be separated, which facilitates the cleaning and maintenance of the U-shaped tube 400 and the air inlet 101.

[0073] Optionally, the breathable rubber 200 is detachably disposed within the air inlet 130. In this way, in the event of a leak in the breathable rubber 200, it can be removed and replaced with a new one in a timely manner, reducing maintenance costs.

[0074] Optionally, the outer wall of the breathable rubber 200 is interference-fitted with the inner wall of the air inlet 130. In this way, the outer wall of the breathable rubber 200 can fit more tightly with the outer wall of the air inlet 130, reducing the risk of the breathable rubber 200 moving on the inner wall of the air inlet 130, thereby reducing the risk of water leakage.

[0075] Optionally, the air inlet 130 is disposed on the lower side wall of the cup holder 110. In this way, the air inlet 130 protrudes from the bottom of the cup holder 110, making it easy for the air inlet 130 to be plugged into the oxygen concentrator.

[0076] Specifically, the air intake nozzle 130 protrudes from the lower side wall of the cup holder 110.

[0077] Optionally, the axis of the air inlet 101 coincides with the axis of the air inlet nozzle 130, and there is a gap between the axis of the air inlet 101 and the axis of the cup body 100. In this way, since the air inlet 101 needs to be connected to the oxygen concentrator, and the axis of the air inlet 101 is spaced from the axis of the cup body 100, the position of the air inlet 101 is relatively far from the axis of the cup body 100 and relatively close to the vertical outer wall of the cup body 100. This makes connecting the air inlet 101 to the oxygen concentrator more convenient and provides a better user experience.

[0078] Optionally, the end of the air inlet 130 facing away from the cup body 100 gradually narrows.

[0079] In some embodiments, an oxygen concentrator includes a humidification cup for an oxygen concentrator as described in the above embodiments.

[0080] The oxygen concentrator provided by this disclosure includes a humidification cup as described in the above embodiment. An appropriate amount of water is added to the cup body 100, and then the cup lid 300 is placed on top of the cup body 100. A breathable rubber 200 is provided inside the air inlet 101 to prevent water in the cup body 100 from flowing downwards from the air inlet 101. Since the air inlet 101 is located at the bottom of the cup body 100, the position of the oxygen concentrator's air outlet 301 can be more clearly observed when the cup body 100 is inserted into the oxygen concentrator. The user can insert the cup body 100 into the oxygen concentrator without having to squat down, making operation more convenient and improving the user experience. Furthermore, gas can enter the cup body 100 through the breathable rubber 200, and the gas in the cup body 100 then passes through the water in the cup body 100 and is discharged through the air outlet 301.
