Description

Technical Field

[0001] This utility model relates to an oxygen generator, and more particularly to a ceiling oxygen generator air vent assembly. Background Technology

[0002] In modern homes and medical settings, oxygen concentrators are widely used as essential medical devices to provide clean, high-concentration oxygen to meet the needs of patients or users. Traditional oxygen concentrators typically connect to a fixed location via piping to supply oxygen. However, this method has several limitations in practical applications, such as inconvenient layout and low flexibility of use. To address these issues, an innovative solution has emerged—the ceiling-mounted oxygen concentrator. By installing it in the room's ceiling, the oxygen-generating device is placed closer to the user, allowing for direct oxygen supply and significantly improving convenience and comfort.

[0003] Rooftop oxygen concentrators are popular due to their ease of installation and small footprint. However, they also present some inconveniences in actual use, especially when opening or closing the vents, where limited space often causes discomfort for users.

[0004] To improve this situation, various designs have emerged on the market to enhance the ease of operation of ceiling-mounted oxygen concentrators. For example, some manufacturers have optimized the vent structure, allowing users to open the vent by rotating it. However, the knob valve requires considerable force to turn, which is not user-friendly for those with weak hands (such as arthritis patients or frail patients). Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a roof oxygen generator air outlet assembly that is compact in structure, easy to switch on and off, labor-saving, and has good performance.

[0006] This utility model provides a ceiling oxygen generator air vent assembly, including:

[0007] The housing has a chamber 10 formed inside it. The side wall of the chamber 10 is provided with an air inlet for connecting to the outlet end of the oxygen generator. The bottom of the chamber 10 is provided with an air outlet 100 for air outlet and can accommodate a finger.

[0008] Valve block 2 is slidably fitted in the chamber 10 and can move between a first position and a second position. When it is in the first position, valve block 2 can block the air outlet 100 and close the air outlet 100. When it is in the second position, valve block 2 moves away from the air outlet 100 and opens the air outlet 100.

[0009] The elastic component 3 is disposed between the valve block 2 and the housing, and tends to move the valve block 2 toward the first position;

[0010] The locking assembly includes a locking block 5 disposed on the upper end of the valve block 2 and a push-type spring lock 6 disposed on the upper end of the housing and capable of engaging or disengaging from the locking block 5.

[0011] Compared to existing rotary switches, this application adopts a sliding valve block and a press-type spring latch 6 structure. Users can easily switch the opening and closing state of the damper by simply pressing the valve block, which greatly reduces the difficulty of operation and is especially suitable for people with weak hand strength, thus improving the overall user experience.

[0012] Furthermore, the valve block 2 is vertically slidably mounted directly above the air outlet 100, and its sliding direction is parallel to the axis of the air outlet 100; its pushing force when pressed is parallel to the sliding direction of the valve block 2, making operation more convenient and effortless, avoiding excessive hand force, and providing a good user experience.

[0013] Furthermore, the edge of the air outlet 100 is provided with an upward-facing first sealing surface 111, and the edge of the valve block 2 is provided with a downward-facing second sealing surface that can fit against the first sealing surface 111; this can improve the sealing performance in the closed state, prevent gas leakage, and provide good performance. At the same time, it can avoid leakage causing wind noise and ensure a quiet and comfortable indoor environment.

[0014] Furthermore, the inner wall of the chamber 10 narrows from top to bottom to form an air guide surface 10a; it forms a conical structure with a large upper end and a small lower end, which allows the air to be blown out at an angle downwards, enhancing the airflow coverage area, improving the uniformity of oxygen distribution, and reducing wind noise.

[0015] Furthermore, the edge of the air outlet 100 extends radially inward to form a limiting part, and the upper surface of the limiting part forms the first sealing surface 111, which serves as a limiting structure for the valve block to prevent the valve block from moving, and at the same time serves as a carrier for setting the sealing surface.

[0016] Furthermore, the lower end of the valve block 2 is provided with a panel 22 that has the same shape as the air outlet 100. When in the first position, the bottom surface of the panel 22 is flush with the bottom surface of the housing. Making the panel 22 flush with the bottom surface of the housing improves the overall aesthetics and facilitates finger pressing operation, reduces the depth of finger insertion during operation, improves operating comfort, and enhances the user experience. At the same time, the above structure allows for quick determination of the air outlet's on / off status.

[0017] Furthermore, the panel 22 is made of rubber or has a rubber layer coated on its bottom surface, which can improve friction, prevent fingers from slipping, ensure operational stability, and at the same time achieve soft contact and good operating feel.

[0018] Furthermore, the top of the chamber is provided with one or more guide posts 42 facing the air outlet 100, and the top of the valve block 2 is provided with guide holes 211 corresponding to the guide posts 42. The guide posts 42 are sleeved in the guide holes 211 and realize the sliding fit of the valve block 2. Through the above structure, the sliding installation of the valve block 2 is realized. Its structure is compact, effectively controls the overall volume, has low manufacturing cost, and is easy to assemble.

[0019] Furthermore, the top of the valve block 2 is provided with a spring mounting hole 210, the elastic component 3 is a compression spring and is installed in the spring mounting hole 210, and the guide hole 211 is opened on the bottom surface of the spring mounting hole 210; it can realize the hidden installation of the spring, improve the structural compactness, reduce the installation space, and at the same time, ensure the smooth sliding of the valve block, avoid deflection or jamming, and extend the service life.

[0020] Furthermore, the housing includes a lower housing 1 with an open upper end and a top cover 4 disposed at the open upper end of the lower housing 1. The top cover 4 is provided with a mounting base 43, and the push-type spring lock 6 is mounted on the mounting base 43 and located on the movement path of the lock block 5. It adopts a split structure, which is convenient to process, has low manufacturing cost, and is easy to assemble and maintain.

[0021] Furthermore, the lower housing 1 includes a decorative panel 11 and a cylindrical body 12 disposed on the decorative panel 11, and the air outlet 100 is opened on the decorative panel 11; this facilitates overall assembly and has an aesthetically pleasing appearance.

[0022] This utility model relates to a ceiling-mounted oxygen concentrator air vent assembly. Compared to existing rotary switches, this application adopts a sliding valve block and a press-type spring lock structure. Users can easily switch the air vent opening and closing state by simply pressing the valve block, greatly reducing the difficulty of operation. It is especially suitable for people with weak hand strength and improves the overall user experience. The chamber adopts a conical structure with a larger upper end and a smaller lower end, which allows the air to blow downwards at an angle, increasing the airflow coverage area, improving the uniformity of oxygen distribution, and reducing wind noise, resulting in better user comfort. The panel not only improves the overall aesthetics but also facilitates finger pressing operation, reducing the depth of finger insertion during operation and improving operating comfort and user experience. The shell adopts a split structure, which is convenient to process, has low manufacturing cost, and facilitates overall assembly and installation. This utility model's ceiling-mounted oxygen concentrator air vent assembly has a compact structure, beautiful appearance, convenient and labor-saving operation, and a good user experience.

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] See Figures 1-9 This utility model provides a ceiling oxygen generator air vent assembly that can be switched on or off by a push-button mechanism, and includes a housing, a valve block 2, and a locking assembly.

[0034] A chamber 10 is formed inside the housing. An air inlet is provided on the side wall of the chamber 10, which is used to connect to the outlet end of the oxygen generator as the oxygen intake end. An air outlet 100 is provided at the bottom of the chamber 10 for air outlet. The air outlet 100 can be inserted into the outlet for pressing operation. A valve block 2 is slidably fitted in the chamber 10 and can move between a first position and a second position. When it is in the first position, the valve block 2 can block (block and close) the air outlet 100, thereby closing the air outlet 100. When it is in the second position, the valve block 2 moves away from the air outlet 100, thereby opening the air outlet 100. An elastic component 3 is provided between the valve block 2 and the housing. The elastic component 3 is a compression spring, which makes the valve block 2 tend to move towards the first position, and also makes the valve block 2 tend to move towards the air outlet 100.

[0035] The latch assembly includes a locking block 5 and a push-type spring latch 6. The locking block 5 is located on the upper end of the valve block 2, and the push-type spring latch 6 is located on the upper end of the housing and faces the locking block 5. The locking block 5 can engage or disengage with the push-type spring latch 6. The locking block 5 and the push-type spring latch 6 can be unlocked and locked by pressing, achieving quick engagement. The locking block 5 and the push-type spring latch 6 are existing technologies, such as the latch structure disclosed in CN111043574; it is also called a door lock switch, such as the existing patent CN221779263U, which is also called a push-type latch, etc. It is existing technology, so it will not be described in detail in this article.

[0036] Compared to existing rotary switches, this application adopts a sliding valve block and a press-type spring latch 6 structure. Users can easily switch the opening and closing state of the damper by simply pressing the valve block, which greatly reduces the difficulty of operation and is especially suitable for people with weak hand strength, thus improving the overall user experience.

[0037] In this application, the valve block 2 is vertically slidably mounted directly above the air outlet 100. The sliding direction of the valve block 2 is parallel to the axis of the air outlet 100. In this embodiment, it is perpendicular to the horizontal plane. The pushing force when it is pressed is parallel to the sliding direction of the valve block 2, making the operation more convenient and effortless, avoiding excessive force from the hand, and providing a good user experience.

[0038] Specifically, one or more guide posts 42 facing the air outlet 100 are provided at the top of the chamber. In this embodiment, the guide post 42 is vertically arranged and located directly above the air outlet 100. At the same time, a guide hole 211 corresponding to the guide post 42 is opened at the top of the valve block 2. The guide post 42 is sleeved in the guide hole 211, thereby realizing the sliding installation of the valve block 2 in the chamber. Through the above structure, the sliding installation of the valve block 2 is realized. Its structure is compact, effectively controls the overall volume, has low manufacturing cost, and is easy to assemble. A spring mounting hole 210 is provided on the top of the valve block 2. The elastic component 3 is a compression spring, which is installed in the spring mounting hole 210. The upper end of the spring contacts the top surface of the chamber, and the lower end contacts the bottom surface of the spring mounting hole, so that the valve block 2 is always subjected to a downward elastic force, even if the valve block has a downward movement tendency. The guide hole 211 is opened on the bottom surface of the spring mounting hole 210, and its diameter is smaller than the diameter of the spring mounting hole. The above structure realizes the concealed installation of the spring, improves the structural compactness, reduces the installation space, and at the same time, ensures the smooth sliding of the valve block, avoids deflection or jamming, and extends the service life.

[0039] To improve airtightness, the edge of the air outlet 100 is provided with an upward-facing first sealing surface 111, while the edge of the valve block 2 is provided with a downward-facing second sealing surface. The second sealing surface can fit against the first sealing surface 111 and achieve a seal. This improves the sealing performance in the closed state, prevents gas leakage, has a good performance, and avoids wind noise caused by leakage, ensuring a quiet and comfortable indoor environment. Specifically, the edge of the air outlet 100 extends radially inward to form a limiting part. The upper surface of the limiting part forms the first sealing surface 111. This limiting part serves as a limiting structure for the valve block, preventing the valve block from moving, and also serves as a carrier for setting the sealing surface.

[0040] In this application, the inner wall of the chamber 10 narrows from top to bottom (the diameter decreases) to form an air guide surface 10a. The air guide surface 10a is an inclined surface, which in turn forms a conical structure with a large upper end and a small lower end. The air guide surface 10a can make the air blow out at an angle downwards, which enhances the airflow coverage area, improves the uniformity of oxygen distribution, and at the same time reduces wind noise and improves the comfort of use.

[0041] To further improve user comfort, this application provides a panel 22 at the lower end of the valve block 2, which has a shape and size that are basically the same as the air outlet 100. When in the first position, the bottom surface of the panel 22 is flush with the bottom surface of the housing. This flushness improves the overall aesthetics and facilitates finger pressing operation, reducing the depth of finger insertion during operation, thus improving operational comfort and user experience. Furthermore, the above structure allows for quick determination of the air outlet's on / off status. To further enhance operational comfort, the panel 22 is made entirely of rubber, or a rubber layer is coated on the bottom surface of the panel 22. This increases friction, prevents finger slippage, ensures operational stability, and provides a soft contact feel.

[0042] To facilitate manufacturing and assembly, the housing in this application adopts a split structure. Specifically, it includes a lower housing 1 with an open upper end and a top cover 4 located at the open upper end of the lower housing 1. The top cover 4 is provided with a mounting base 43, and a push-type spring lock 6 is installed on the mounting base 43 with its working end facing downward. The push-type spring lock 6 is located on the movement path of the locking block 5. When the locking block 5 contacts the push-type spring lock 6, pressing it will lock the two together, and pressing it again will unlock it, achieving a quick fastening connection. The guide post is also located at the lower end of the top cover. The housing adopts a split structure, which is convenient to process, has low manufacturing cost, and is easy to assemble and maintain. The lower housing 1 includes a decorative panel 11 and a cylindrical body 12 located on the decorative panel 11. The air outlet 100 is opened on the decorative panel 11. It is convenient to process and assemble, and has an aesthetically pleasing appearance.

[0043] In this embodiment, the cross-section of the chamber and valve block is circular, and the air outlet is rectangular, preferably square. This reduces wind resistance and wind noise, while ensuring uniform airflow distribution, further improving indoor air circulation and optimizing user experience.

[0044] This utility model relates to a ceiling-mounted oxygen concentrator air vent assembly. Compared to existing rotary switches, this application adopts a sliding valve block and a press-type spring lock structure. Users can easily switch the air vent opening and closing state by simply pressing the valve block, greatly reducing the difficulty of operation. It is especially suitable for people with weak hand strength and improves the overall user experience.
