Description

Technical Field

[0001] This utility model relates to the field of oxygen generator technology, and in particular to a portable system upper cover structure. Background Technology

[0002] The top cover of the portable system is used inside the oxygen generator to seal the top of the molecular sieve cylinder, ensuring that the high-pressure gas enters the molecular sieve adsorption layer in a directional manner after compression, and preventing gas leakage from affecting the oxygen separation efficiency.

[0003] Currently, when installing the top cover with the molecular sieve, silicone is usually pre-installed and sealed with molecular sieve silicone. This method has a high degree of integration, but replacement or maintenance requires disassembling the entire machine, which is complicated and time-consuming. Furthermore, silicone is prone to aging and hardening when exposed to a humid and hot environment for a long time, which can lead to seal failure, gas leakage, or impurity infiltration, thereby affecting the normal use of the system. In view of this, this utility model is proposed. Utility Model Content

[0028] 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.

[0029] 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.

[0030] Reference Figures 1-4 A portable system top cover structure includes: a substrate 1, and an annular flange 101 surrounding the outer edge of the substrate 1; a closed protrusion 102 is provided on the substrate 1, and a molecular sieve connecting groove 103 is formed between the flange 101 and the closed protrusion 102; a first arc groove 105 is provided at the corner of the substrate 1, and a first mounting hole 106 corresponding to the position of the first arc groove 105 is provided on the substrate 1; a through hole 104 and an air outlet 2 are also provided on the substrate 1, the air outlet 2 is provided at the bottom of the substrate 1, and the position of the air outlet 2 corresponds to that of the through hole 104; the flange 101 is integrally formed with the substrate 1.

[0031] In this invention, when installing the molecular sieve tower, the molecular sieve cylinder is directly inserted into the molecular sieve connecting groove 103 between the flange 101 and the closed protrusion 102 for fixation. The gas inside the molecular sieve can pass through the through hole 104. There are two closed protrusions 102 and two through holes 104, each located within one of the two closed protrusions 102. Two gas outlets 2 are also provided, each connected to one of the two through holes 104. Two molecular sieve towers can be connected through the two closed protrusions 102, and the two through holes 104 are located within the two closed protrusions 102, allowing for gas intake and exhaust operations through the two gas outlets 2. This facilitates the normal use of the upper end cap. In this application, the end cap is designed as an integrated structure, which is convenient for installation and use. When the molecular sieve tower needs maintenance, the end cap can be removed directly. Furthermore, the integrated design provides better sealing performance, preventing gas leakage or impurity infiltration, thus improving the overall service life of the system.

[0032] Specifically, after the molecular sieve is installed in the molecular sieve connecting groove 103, the base of the molecular sieve is placed in the first arc groove 105, and then bolts are connected in the first mounting hole 106 to fix the molecular sieve and the substrate 1, thereby completing the installation of the upper end cover. The installation and disassembly are convenient and quick, and easy to use.

[0033] Reference Figures 1-4 The substrate 1 is also provided with a second mounting hole 108, which is located in the middle of the two closed protrusions 102. The flange 101 is provided with a second arc groove 107 corresponding to the position of the second mounting hole 108. Since the end cap can connect two molecular sieve towers at the same time, the middle position of the two molecular sieve towers can be fixed and installed through the provided second arc groove 107 and second mounting hole 108, which improves stability and further ensures sealing performance.

[0034] Reference Figures 1-4 The air outlet 2 has a groove 201, and an annular sealing ring 3 is connected inside the groove 201. The bottom of the air outlet 2 has a slope 202.

[0035] In use, this utility model first connects pipes to the two air outlets 2. Gas can enter through one pipe and then exit through the other pipe. The end of the air outlet 2 is provided with a bevel 202, which makes it easier to insert the pipe into the air outlet 2. The provided annular sealing ring 3 can seal the connection between the air outlet 2 and the pipe to prevent gas leakage. At the same time, the annular sealing ring 3 can also make the connection between the pipe and the air outlet 2 tighter and prevent it from falling off during use.

[0036] Refer to the image- Figure 6The flange 101 is provided with a limiting hole 4 that communicates with the molecular sieve connecting groove 103, and a limiting block 403 is slidably connected in the limiting hole 4.

[0037] A support plate 404 is fixedly connected inside the limiting hole 4. A threaded block 405 is provided on the support plate 404. A threaded rod 402 is threadedly connected to the threaded block 405. The threaded rod 402 is rotatably connected to the limiting block 403. A sprite head 401 is fixedly connected to the end of the threaded rod 402 away from the limiting block 403. The sprite head 401 is also placed inside the limiting hole 4.

[0038] In this invention, after the molecular sieve tower is installed in the molecular sieve connecting groove 103, the screwdriver is used to turn the screw head 401, which drives the threaded rod 402 to rotate. This causes the threaded rod 402 to mesh with the threaded block 405 on the support plate 404, thereby moving the threaded rod 402 and simultaneously moving the limiting block 403. The limiting block 403 then moves out and abuts against the cylinder wall of the molecular sieve tower, thus further fixing the molecular sieve tower.

[0039] 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.
