Description

Technical Field

[0001] This utility model relates to the field of oxygen outlet technology, and in particular to a self-locking oxygen outlet. Background Technology

[0002] Oxygen concentrators separate oxygen from the air using physical or chemical methods. Modern equipment often employs molecular sieve pressure swing adsorption, utilizing the preferential adsorption characteristics of nitrogen under pressure to separate oxygen and nitrogen. This method features low energy consumption and high portability, and the equipment is widely used in medical emergency care, high-altitude hypoxia relief, industrial welding, and aquaculture. Currently, the oxygen outlet nozzles used in traditional oxygen concentrators require nuts to connect and fix them, which is cumbersome during installation and reduces the efficiency of oxygen concentrator production and installation. Based on this, this utility model is proposed. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model.

[0027] Example 1: Refer to Figures 1-6 A self-locking oxygen nozzle includes a disc-shaped support platform 2, and further includes: an oxygen nozzle assembly 1 fixedly connected to the support platform 2, the oxygen nozzle assembly 1 being connected to an oxygen hose; a threaded connector 21 fixedly connected to the support platform 2, the threaded connector 21 being threadedly connected to an oxygen generator; an installation hole 22 is provided on the support platform 2, a compressed air hole 14 is provided inside the oxygen nozzle assembly 1, the oxygen nozzle assembly 1 includes an auxiliary inclined surface 11, a locking inclined surface 12 and a transition rod 13, the auxiliary inclined surface 11 and the locking inclined surface 12 together forming an interference fit end.

[0028] Unlike common oxygen outlet nozzles, this invention requires a nut to connect and fix the nozzle to the oxygen concentrator. In this device, a threaded connector 21 is fixedly connected to the lower end of the support platform 2, allowing direct connection to the oxygen concentrator via threads. To facilitate the installation of the oxygen outlet nozzle, an installation hole 22 is provided on the support platform 2. An extension rod is inserted into the installation hole 22 to rotate and install the oxygen outlet nozzle. This installation method effectively improves the production efficiency of the portable oxygen concentrator and also effectively solves the problem of tamper protection. A small-diameter compressed air hole 14 is provided in the oxygen outlet nozzle assembly 1, allowing oxygen to be discharged with a strong airflow when passing through the compressed air hole 14.

[0029] The oxygen outlet assembly 1 includes three surfaces. The auxiliary inclined surface 11 allows the user to easily connect the oxygen inhalation hose to the oxygen outlet assembly 1. The protruding part where the auxiliary inclined surface 11 and the locking inclined surface 12 meet forms an interference fit end. When the oxygen inhalation hose reaches the interference fit end, the two are in an interference fit, which allows the oxygen inhalation hose to be fixed after being inserted into the oxygen outlet assembly 1.

[0030] Example 2: Refer to Figures 1-6 Similar to Embodiment 1, but further: a threaded cylinder 41 is threadedly connected to the transition rod 13, and an adjusting cylinder 4 is fixedly connected to the outside of the threaded cylinder 41. A sliding arc groove 42 is provided inside the adjusting cylinder 4. A snap-fit ​​assembly 3 is slidably connected inside the oxygen outlet assembly 1. The snap-fit ​​assembly 3 includes a sliding sleeve 32, a transition arc plate 33, a compression arc plate 34, and a sliding arc plate 35. The transition arc plate 33 and the sliding sleeve 32 are fixedly connected. The connection between the transition arc plate 33 and the sliding sleeve 32 has a certain elastic deformation capability. The transition arc plate 33 and the compression arc plate 34 form an elastic support end. A limiting arc block 36 is fixedly connected to the sliding arc plate 35. The limiting arc block 36 is slidably connected inside the sliding arc groove 42. A blocking plate 31 is fixedly connected inside the sliding sleeve 32. When the blocking plate 31 is blown upward by gas, the snap-fit ​​assembly 3 expands outward. Multiple transition arc plates 33 together form an annular cylindrical sleeve for connecting with the oxygen hose.

[0031] In this invention, the snap-fit ​​assembly 3 is slidably connected to the oxygen outlet assembly 1, and the connection between the extrusion arc plate 34 and the transition arc plate 33 forms an elastic support end. When the snap-fit ​​assembly 3 is located in... Figure 4When the position shown is such that there is a certain gap between the locking assembly 3 and the oxygen outlet assembly 1, when the oxygen tubing is inserted into the locking assembly 3, it will squeeze the locking assembly 3 towards the center. At this time, the oxygen tubing can be easily fitted onto the outside of the locking assembly 3. When the locking assembly 3 moves upward, the compression arc plate 34 contacts the locking inclined surface 12, and under the action of the locking inclined surface 12, it will squeeze the compression arc plate 34 to expand outward, thereby fixing the oxygen tubing. When it is necessary to remove the oxygen tubing, simply move the locking assembly 3 back to the position shown. Figure 4 The oxygen tubing can be easily removed from the snap-fit ​​assembly 3 at the indicated position;

[0032] The sliding arc plate 35 slides in the sliding arc groove 42 through the limiting arc block 36. There is a certain gap between the limiting arc block 36 and the inner wall of the sliding arc groove 42. When the adjusting cylinder 4 is rotated, the adjusting cylinder 4 moves upward and pushes the snap-fit ​​component 3 upward through the sliding arc groove 42, so that the elastic support end expands outward during the compression process.

[0033] The sliding sleeve 32 is fixedly connected to a baffle plate 31. When oxygen is discharged from the oxygen outlet assembly 1, it will push the locking assembly 3 to move further upward, thereby making the connection between the locking assembly 3 and the oxygen hose more secure when the oxygen outlet assembly 1 is ventilated.

[0034] When using the device, the user simply inserts the oxygen tubing into the locking assembly 3, and then rotates the adjusting cylinder 4 to push the locking assembly 3 upward, thereby enhancing the connection stability between the locking assembly 3 and the oxygen tubing. After use, the user rotates the adjusting cylinder 4 to move the locking assembly 3 downward, and the oxygen tubing can be removed from the locking assembly 3.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
