Description

Technical Field

[0001] This utility model belongs to the technical field of oxygen outlet valve structure, specifically relating to a diffusion knob type oxygen outlet structure. Background Technology

[0002] Oxygen concentrators produce oxygen using various principles, such as air separation technology and molecular sieve physical adsorption and desorption, to meet the oxygen needs of those requiring oxygen therapy. Existing conventional diffusion-type oxygen concentrators require a diffused, adjustable oxygen release method. Current diffusion outlet structures only allow for limited flow rate adjustments and minor steering adjustments. Their advantages include low manufacturing costs; however, they suffer from insufficient convenience and practicality, a large overall size, and wasted installation space. Therefore, it is necessary to develop a novel diffusion-type oxygen concentrator with a rotary knob-style oxygen outlet structure. Utility Model Content

[0003] This invention addresses the aforementioned problems and overcomes the shortcomings of existing technologies by providing a diffusion knob-type oxygen outlet structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution.

[0005] This utility model provides a diffusion knob-type oxygen outlet structure, including a rotating ball, a diffusion panel, a rotating ball support, and a fixing nut. The rotating ball is equipped with an airway knob mechanism, and is clamped between the diffusion panel and the rotating ball support. The diffusion panel and the rotating ball support are connected by threads to adjust the universal tightness of the rotating ball. The airway knob mechanism includes an airway knob cover, an airway rotating column, a sealing gasket, and an air inlet plate. The airway knob cover is axially floated and limited by a limiting screw and the airway rotating column. A compression spring is provided between the limiting screw and the airway knob cover. The airway rotating column, the sealing gasket, and the air inlet plate are axially fixed inside the rotating ball by a retaining spring. The diffusion panel and the fixing nut are connected by threads to clamp and fix the diffusion knob-type oxygen outlet structure to the mounting surface.

[0006] Furthermore, the lower end face of the air passage knob cover is provided with a protrusion, and the spherical end face opposite to the lower end face of the air passage knob cover is provided with a concave point that matches the protrusion; the air passage knob cover is connected to the slot on the air passage rotating column through a locking platform on its bottom surface, so that rotating the air passage knob cover can drive the air passage rotating column to rotate synchronously; when rotating the air passage knob cover separates the protrusion and the concave point, the air passage knob cover is pressed upward and compresses the compression spring; when the protrusion rotates to coincide with the next concave point, under the elastic force of the compression spring, the air passage knob cover resets and presses down, providing a tactile feel for gear switching.

[0007] Furthermore, the airway knob cover and the airway rotating column are respectively provided with multiple interconnected air outlet channels, each with a different diameter. The air inlet port plate and the sealing gasket are provided with concentric air inlet holes. Rotating the airway knob cover can selectively connect different air outlet channels with the air inlet holes, thereby realizing multi-level adjustment of oxygen flow rate.

[0008] Furthermore, the rotating ball has a universal rotating surface, and the diffusion panel is provided with a first universal ball limiting surface that fits with the universal rotating surface, and the rotating ball support is provided with a second universal ball limiting surface that fits with the universal rotating surface; by adjusting the thread fit depth between the diffusion panel and the rotating ball support, the clamping force on the rotating ball is changed, thereby realizing the stepless adjustment and locking of the universal rotation angle of the rotating ball.

[0009] Furthermore, a sealing ring is provided inside both the diffusion panel and the rotating ball holder for sealing when the ball rotates in all directions.

[0010] Furthermore, the intake port plate is provided with limiting ears on both sides, and the inside of the rotating ball is provided with limiting grooves that cooperate with the limiting ears to prevent the intake port plate from rotating; the sealing gasket is provided with a boss, and the intake port plate is provided with a recess that cooperates with the boss to achieve radial limiting between the sealing gasket and the intake port plate.

[0011] Furthermore, the side of the fixing nut is provided with a fastening screw hole for screwing in a fastening screw to tighten the fixing nut.

[0012] The beneficial effects of this utility model are:

[0013] Compared with the prior art, the diffusion knob oxygen outlet structure provided by this utility model combines the set airway knob cover, compression spring, airway rotating column and rotating ball to form a structure that, when used in a conventional diffusion oxygen generator, can not only meet the multi-level adjustment of oxygen output air volume, but also achieve more accurate level adjustment, better tactile feel, and more convenient overall assembly.

[0025] To make the technical problems solved, the technical solutions, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Combination Figures 1 to 5 As shown in the figure, the present invention provides a diffusion knob type oxygen outlet structure, including a rotating ball 2, a diffusion panel 4, a rotating ball support 5, and a fixing nut 3; the rotating ball 2 is provided with an airway knob mechanism, the rotating ball 2 is clamped between the diffusion panel 4 and the rotating ball support 5, and the diffusion panel 4 and the rotating ball support 5 are connected by threads to adjust the universal tightness of the rotating ball 2. The airway knob mechanism, as the core adjustment component, specifically includes an airway knob cover 1, an airway rotating column 6, a sealing gasket 8, and an air inlet plate 7. The airway knob cover 1 is clearance-fitted with the mating surface 62 of the airway rotating column 6 via its countersunk side 11, and is axially floated and limited by a limiting screw 9. The limiting screw 9 is housed in the spring fixing slot hole 13 of the airway knob cover 1, and a compression spring 10 is provided between the end face of the limiting screw 9 and the spring fixing slot hole 13. The airway rotating column 6 is axially limited inside the rotating ball 2 by its snap-fit ​​limiting flange 61, and the airway rotating column 6, the sealing gasket 8, and the air inlet plate 7 are finally axially fixed inside the rotating ball 2 by a snap spring. The airway knob mechanism can rotate freely relative to the rotating ball 2. The dispersion panel 4 and the fixing nut 3 are connected by threads, and together they clamp and fix the entire dispersion knob-type oxygen outlet structure firmly to the mounting surface.

[0027] Specifically, to achieve clear tactile feedback of gear shifting, the lower end face of the air passage knob cover 1 is provided with a protrusion 12, and its countersunk end face 15 is used to press against the upper surface of the air passage rotating column 6. Correspondingly, the end face of the rotating ball 2 opposite to the lower end face of the air passage knob cover 1 is provided with a concave point 21 that cooperates with the protrusion 12. The air passage knob cover 1 cooperates with the slot 63 on the air passage rotating column 6 through the locking platform 14 on its bottom surface, so that rotating the air passage knob cover 1 can drive the air passage rotating column 6 to rotate synchronously. Its working principle is as follows: when rotating the air passage knob cover 1 separates the protrusion 12 from the concave point 21, the air passage knob cover 1 is pressed upward and compresses the compression spring 10; when the protrusion 12 rotates to coincide with the next concave point 21, under the elastic force of the compression spring 10, the air passage knob cover 1 returns to its original position and presses down, so that the countersunk end face 15 is pressed tightly against the upper surface of the air passage rotating column 6, thereby providing clear tactile confirmation for each gear shift.

[0028] Specifically, when the air passage knob cover 1 rotates, the contact between the concave point 21 and the convex point 12 indicates a successful gear shift. The air passage knob cover 1 and the air passage rotating column 6 can move axially relative to each other, with the maximum movement limited by the limit screw 9. When the air passage knob cover 1 rotates, it drives the air passage rotating column 6 to rotate. When the convex point 12 of the air passage knob cover 1 separates from the concave point 21 of the rotating ball 2, the air passage knob cover 1 moves upward relative to the end face of the rotating ball 2. At this time, the compression spring 10 is compressed. When the convex point 12 of the air passage knob cover 1 rotates to the concave point 21 on the end face of the rotating ball 2, the air passage knob cover 1, under the elastic force of the compression spring 10, presses its lower end face firmly against the end face of the rotating ball 2. The increased damping in the rotation direction under the elastic force of the compression spring 10 provides a clear sense of separation in the gear selection action, offering a good user experience.

[0029] Specifically, to achieve multi-level adjustment of oxygen flow rate, the airway knob cover 1 and the airway rotating column 6 are equipped with multiple interconnected air outlet channels, each with a different diameter. Simultaneously, concentric air inlet holes are provided on the air inlet port plate 7 and the sealing gasket 8. By rotating the airway knob cover 1, users can selectively connect different air outlet channels on the airway rotating column 6 to the air inlet holes, thereby precisely controlling the oxygen output to meet different usage needs. The rotating ball support 5 has a built-in oxygen inlet, which is connected to the air inlet hole on the air inlet port plate 7.

[0030] Specifically, the omnidirectional adjustment function of the rotating ball 2 is achieved through its special structure. The rotating ball 2 has a spherical omnidirectional rotating surface 22, and the diffusion panel 4 is provided with a first omnidirectional limiting surface 41 that fits against the omnidirectional rotating surface 22. The rotating ball support 5 is provided with a second omnidirectional limiting surface 51. By adjusting the threaded engagement depth between the diffusion panel 4 and the rotating ball support 5, the clamping force on the rotating ball 2 can be changed, thereby achieving stepless adjustment and reliable locking of the omnidirectional rotation angle of the rotating ball 2, making it convenient for users to guide the oxygen flow in the desired direction.

[0031] Specifically, to ensure the structure's airtightness during omnidirectional rotation, a sealing ring is installed inside both the dispersion panel 4 and the rotating ball holder 5. This design ensures that the entire oxygen outlet structure maintains a good sealing effect and prevents gas leakage even when the rotating ball 2 rotates at multiple angles.

[0032] Specifically, to prevent unintended rotation of internal components, limit ears are provided on both sides of the air intake port plate 7, and the rotating ball 2 has a limiting groove inside that mates with the limit ears. This structure effectively prevents the air intake port plate 7 from rotating on its own. In addition, a boss is provided on the sealing gasket 8, and a recess is provided on the air intake port plate 7 that mates with the boss. This design achieves radial limiting between the sealing gasket 8 and the air intake port plate 7, ensuring the structural stability after assembly.

[0033] Specifically, the fixing nut 3 and the dispersion panel 4 are connected by threads to form a mounting clamping structure. During actual installation, the dispersion panel 4 is first pressed firmly against the mounting surface, and then the fixing nut 3 is tightened. The threaded movement securely clamps the mounting surface between the fixing nut 3 and the dispersion panel 4. To further improve installation reliability, a fastening screw hole is provided on the side of the fixing nut 3. After installation and clamping, a fastening screw can be screwed into this hole, thus completely preventing the fixing nut 3 from loosening during use and ensuring the long-term stability of the overall structure.

[0034] In summary, this invention not only achieves good oxygen output in diffused oxygen supply but also allows for adjustable airflow levels. Furthermore, the tactile feedback when adjusting the airflow level via the rotating air duct knob cover 1 enhances the user-friendliness and feel. Additionally, the placement of the fixed panel between the diffused panel 4 and the fixing nut 3 minimizes the bulk of the protruding head structure, making it convenient for installation and use in vehicles or indoors.

[0035] It is understood that the above specific description of this utility model is only used to illustrate this utility model and is not limited to the technical solutions described in the embodiments of this utility model. Those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model to achieve the same technical effect; as long as the use needs are met, they are all within the protection scope of this utility model.
