Description

Technical Field

[0001] This utility model relates to the field of oxygen generator equipment, and in particular to an anti-clogging structure for the oxygen outlet of an oxygen generator. Background Technology

[0002] Oxygen concentrators, as important medical aids and health devices, provide great convenience for users who need additional oxygen support. Their core function is to separate nitrogen and other components from the air, enrich oxygen, and then output it to users. With the popularization of oxygen concentrators and the extension of user usage time, the problem of oxygen outlet blockage has become increasingly prominent. First, water vapor in the air is not completely removed during the oxygen production process, or it condenses into water droplets in low-temperature environments. Second, dust and fine particulate matter in the environment inevitably enter the oxygen outlet area with the airflow. These condensed water droplets and accumulated dust combine to gradually form obstructions near the oxygen outlet, resulting in a reduction in the flow cross-section of the pipe or even complete blockage. When the oxygen outlet is blocked, it affects the oxygen output efficiency of the oxygen concentrator. To address this issue, we provide an anti-blockage structure for the oxygen outlet of an oxygen concentrator to solve the above problems. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an anti-clogging structure for the oxygen outlet of an oxygen generator, thus solving the problems mentioned in the background section.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: an anti-clogging structure for the oxygen outlet of an oxygen generator, comprising a connecting block, wherein the connecting block has an internal thread, a filter plate is installed inside the connecting block, an mounting block is provided inside the connecting block, the outer surface of the mounting block is provided with an external thread adapted to the internal thread, the mounting block is threadedly connected to the inside of the connecting block through the mating of the external thread and the internal thread, and a folding soft pad is provided on the left side of the mounting block.

[0005] As a further technical solution of this utility model, a first connector is installed on the outer surface of the mounting block, and a second connector is installed on the outer surface of the connecting block.

[0006] As a further technical solution of this utility model, a mounting bracket is installed inside the connecting block, a connecting rod is installed on the outer surface of the mounting bracket, and a mounting rod is installed on the outer surface of the connecting rod.

[0007] As a further technical solution of this utility model, an installation head is installed at the end of the mounting rod away from the connecting rod, and multiple support bones are hinged inside the mounting head.

[0008] As a further technical solution of this utility model, each of the supporting bones has a mounting seat installed on its outer surface, and a transmission rod is rotatably installed inside each of the mounting seats.

[0009] As a further technical solution of this utility model, a slide block is slidably mounted on the outer surface of the mounting rod, and the end of each transmission rod away from the mounting block is rotatably mounted inside the slide block.

[0010] As a further technical solution of this utility model, a spring is sleeved on the outer surface of the mounting rod, the left end of the spring is connected to the outer surface of the slide block, and the right end of the spring is connected to the outer surface of the connecting rod.

[0011] This utility model provides an anti-clogging structure for the oxygen outlet of an oxygen concentrator, which has the following advantages compared with the prior art:

[0012] 1. The oxygen outlet anti-clogging structure for an oxygen generator designed in this paper uses a spring to expand the stacked soft pad, which can tightly fit the inner wall of the oxygen outlet to form a physical barrier. This effectively prevents the condensate that may be generated in the pipeline from flowing back towards the oxygen outlet, thereby ensuring the continuity and efficiency of oxygen output.

[0013] 2. This design provides an anti-clogging structure for the oxygen outlet of an oxygen concentrator. Through the ingenious design of internal and external threads, the mounting block can be easily unscrewed from the connecting block. Since the filter plate is mounted on the mounting block, this design allows users to easily and quickly remove the filter plate for cleaning or replacement without disassembling the entire structure or using complex tools. This device significantly improves the oxygen output efficiency and reliability of the oxygen concentrator. Attached Figure Description

[0019] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution for an anti-clogging structure for the oxygen outlet of an oxygen concentrator: it includes a connecting block 1, an internal thread 14 inside the connecting block 1, a filter plate 16 installed inside the connecting block 1, and an mounting block 2 inside the connecting block 1. The outer surface of the mounting block 2 is provided with an external thread 15 that matches the internal thread 14. The mounting block 2 is threadedly connected to the inside of the connecting block 1 through the mating of the external thread 15 and the internal thread 14. When the mounting block 2 is screwed into the internal thread 14 of the connecting block 1 through the external thread 15, the threaded connection will generate a certain axial force. This force will squeeze the filter plate 16, making it firmly installed in the internal space formed by the connecting block 1 and the mounting block 2, ensuring the filtration effect and structural stability. A folding soft pad 11 is provided on the left side of the mounting block 2. Through the folding soft pad 11, in the open state, it can effectively prevent the generated condensate from flowing back towards the oxygen outlet.

[0021] like Figure 1 As shown, the outer surface of the mounting block 2 is equipped with a first connector 3, and the outer surface of the connecting block 1 is equipped with a second connector 4. The first connector 3 and the second connector 4 can be connected to the oxygen outlet and the subsequent delivery pipeline.

[0022] like Figure 1 and Figure 2 As shown, a mounting bracket 5 is installed inside the connecting block 1, a connecting rod 6 is installed on the outer surface of the mounting bracket 5, and a mounting rod 7 is installed on the outer surface of the connecting rod 6. A mounting head 13 is installed at the end of the mounting rod 7 away from the connecting rod 6. Multiple support bones 12 are hinged inside the mounting head 13. The support bones 12 are inserted into the oxygen outlet. With the use of the spring 10, elastic force is provided to push the support bones 12 and the folded soft pad 11. This makes the support bones 12 and the folded soft pad 11 open inside the oxygen outlet, ensuring the pipeline is unobstructed and preventing the oxygen outlet from being blocked due to folding caused by the structure itself.

[0023] like Figure 1 and Figure 3As shown, each support rib 12 has a mounting base 9 installed on its outer surface, and a transmission rod 8 is rotatably installed inside each mounting base 9. A slide block 17 is slidably installed on the outer surface of the mounting rod 7. The end of each transmission rod 8 away from the mounting base 9 is rotatably installed inside the slide block 17. A spring 10 is sleeved on the outer surface of the mounting rod 7. The left end of the spring 10 is connected to the outer surface of the slide block 17, and the right end of the spring 10 is connected to the outer surface of the connecting rod 6. The spring 10 can continuously provide pressure to the slide block 17, keeping the support rib 12 and the folded soft pad 11 in an open state, preventing them from easily retracting and failing. This also ensures that the folded soft pad 11 is tightly attached to the inner wall of the oxygen outlet, forming a barrier against condensation.

[0024] The working principle of this utility model is as follows: In use, firstly, the second connector 4 is installed inside the oxygen outlet of the oxygen generator. The mounting block 2 is connected to the subsequent delivery pipe through components such as the first connector 3, forming a whole. During installation, after the support rib 12 is inserted into the oxygen outlet, with the cooperation of the mounting base 9, transmission rod 8, and mounting rod 7, the support rib 12 can initially fold and unfold. When fully inserted, the spring 10 acts, providing elastic force to push the support rib 12 and the folding pad 11. This allows the support rib 12 and the folding pad 11 to open inside the oxygen outlet, ensuring unobstructed pipe flow and preventing oxygen leakage due to structural defects. When the outlet is folded and blocked, the folded soft pad 11, when unfolded, can effectively prevent the generated condensate from flowing back towards the oxygen outlet. When the airflow passes through the filter plate 16, it will intercept impurities and dust in the gas, improving the purity of the oxygen output. When the impurities and dust adsorbed on the filter plate 16 accumulate to a certain extent, affecting the filtration effect or causing blockage, the mounting block 2 can be unscrewed from the inside of the connecting block 1 through the cooperation of the internal thread 14 and the external thread 15. Since the filter plate 16 is installed on the mounting block 2, the filter plate 16 can be easily removed for cleaning or replacement by unscrewing the mounting block 2, realizing convenient replacement and cleaning of the filter plate 16.

[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
