Abstract
Description
Technical Field
[0001] This utility model relates to the field of oxygen generator technology, and in particular to an oxygen generator with sterilization function. Background Technology
[0002] Since its inception, oxygen concentrators have been continuously developing. In the early days, they were mainly used in the medical field to assist in the treatment of patients with respiratory diseases. With the advancement of technology, their scope of use has gradually expanded. They are not only widely used in hospitals, but the demand for home oxygen therapy is also increasing. Their portability and oxygen production efficiency have been significantly improved, providing convenience and health protection for people who need oxygen in different scenarios.
[0003] An oxygen concentrator mainly consists of an air compressor, molecular sieve, filter, valve, flow meter, oxygen storage tank, and control circuit. The operation steps are as follows: During the oxygen production process, the air is first compressed by the air compressor and then enters the adsorption tower containing the molecular sieve. When the molecular sieve in the adsorption tower reaches saturation with adsorbed nitrogen, the valve is controlled to switch between high-pressure adsorption and low-pressure desorption, thereby continuously producing oxygen. The produced oxygen is further purified by the filter to remove impurities and trace amounts of moisture, and then the flow rate is adjusted by the flow meter before being output to the user.
[0004] Currently, some oxygen concentrators have significant defects in actual use. Their sterilization process for inhaled air is weak, failing to effectively remove various bacteria, viruses, and other harmful microorganisms. Furthermore, the maintenance of subsequent sterilization components is cumbersome and time-consuming. When this inadequately sterilized air enters the oxygen concentrator and participates in the oxygen production process, it not only leads to microbial corrosion of internal components, shortening the equipment's lifespan and affecting oxygen production performance and efficiency, but also causes the produced oxygen to carry pathogens. When inhaled, this poses a potential threat to the user's respiratory tract and even their overall health, such as causing respiratory infections, allergic reactions, and other adverse symptoms. This seriously reduces the safety and reliability of using oxygen concentrators. Therefore, an oxygen concentrator with sterilization function is proposed to solve the above problems.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figures 1 to 3 This utility model provides an embodiment of an oxygen concentrator with sterilization function, comprising a main body 1. The main body 1 serves as the core support structure of the entire oxygen concentrator, bearing numerous key components and providing a stable foundation for its normal operation. A vent plate 2 is rotatably connected to the main body 1. The vent plate 2 is designed to facilitate operation of internal sterilization components and ensure proper airflow. The vent plate 2 can rotate flexibly relative to the main body 1, facilitating subsequent maintenance and operation. An internal sterilization mechanism is provided in the vent plate 2 to effectively remove impurities from the air and kill various harmful microorganisms, ensuring the purity of the produced oxygen and thus guaranteeing the safety and hygiene of the oxygen inhaled by the user. An external fixing mechanism is provided on the main body 1 for securing the air pipe. This fixing mechanism is crucial, as it firmly secures the air pipe, preventing loosening or even disconnection during operation, thereby ensuring a stable oxygen supply to the user.
[0034] The sterilization mechanism includes a filter screen 3, which acts as the first line of defense, primarily responsible for intercepting larger particles of dust, hair, and other impurities in the air. This prevents these impurities from entering the oxygen generator and affecting the normal operation of subsequent components and the quality of oxygen. The filter screen 3 is externally slidably connected to the inside of the ventilation plate 2. This sliding connection makes the filter screen 3 easy to disassemble and install, allowing it to be removed for cleaning after a period of use to restore its filtering effect. The ventilation plate 2 is slidably connected to a sterilization layer 4, which is one of the core components of the sterilization mechanism. The sterilization layer 4 uses materials or structures with highly efficient sterilization functions (such as those containing special bactericidal coatings or structures utilizing physical sterilization principles), enabling deep sterilization of the air after the initial filtration by the filter screen 3. This kills bacteria, viruses, and other microorganisms, ensuring that the air cleanliness meets the oxygen production requirements.
[0035] The vent plate 2 has a sliding tooth 5 inside, which plays an important role in connecting and fixing the vent plate 2 to the main body 1. Changes in its position and state directly affect the fixation between the vent plate 2 and the main body 1. A telescopic column 6 is fixedly connected to the rear end of the sliding tooth 5. The telescopic column 6 provides guidance and support for the movement of the sliding tooth 5, ensuring that the sliding tooth 5 can move smoothly in a predetermined direction. A telescopic spring 7 is sleeved on the outside of the telescopic column 6. The telescopic spring 7 has good elasticity and can store or release elastic potential energy during the movement of the sliding tooth 5, thereby assisting the sliding tooth 5 in completing the corresponding fixing or loosening action. A control component is provided at the end of the sliding tooth 5 away from the filter screen 3. The presence of the control component facilitates the operator to operate the sliding tooth 5, thereby realizing the switching between fixing and loosening between the vent plate 2 and the main body 1. The front end of the telescopic spring 7 is fixedly connected to the rear end of the sliding tooth 5, and the other end of the telescopic spring 7 is fixedly connected to the inside of the vent plate 2. This connection method allows the telescopic spring 7 to stably exert its elastic effect and accurately push or pull the sliding tooth 5 during corresponding operations.
[0036] The control component includes a sliding block 8, a key connecting part of the control component. The rear end of the sliding block 8 is fixedly connected to the end of the sliding tooth 5 furthest from the filter screen 3, transmitting the external force applied by the operator to the sliding tooth 5 to control its movement. A control rod 9 is rotatably connected to the outside of the sliding block 8. The control rod 9 is directly operated by the operator; rotating and pulling the control rod 9 causes the sliding block 8 to slide, indirectly controlling the movement of the sliding tooth 5, making operation convenient and intuitive. A groove is provided on the outside of the vent plate 2, and the outside of the sliding block 8 is slidably connected to the inside of the groove. The groove provides a defined track for the sliding block 8, ensuring it slides stably in a predetermined direction and preventing deviations that could affect the control of the sliding tooth 5. The control rod 9 is also slidably connected to the inside of the groove, again relying on the groove to ensure its standardized and accurate sliding. The rear end of the telescopic column 6 is fixedly connected to the inside of the vent plate 2, further enhancing the stability and overall integrity of the structure.
[0037] Reference Figure 1 and Figure 4The fixing mechanism includes two rotating rods 12, symmetrically distributed on both sides of the front end of the main body 1. The rear ends of the two rotating rods 12 are rotatably connected to the front end of the main body 1. This rotatable connection allows the rotating rods 12 to rotate flexibly around the connection point, facilitating subsequent clamping operations on the gas pipe. Limiting blocks 13 are fixedly connected to adjacent sides of the two rotating rods 12. The shape and size of the limiting blocks 13 are designed to fit the outer contour of the gas pipe, allowing them to conform to the outside of the gas pipe and provide initial limiting to prevent lateral displacement of the gas pipe. Two rotating rods 14 are rotatably connected to the bottom end of one of the limiting blocks 13. The rotating rods 14 can rotate around their connection point with the limiting block 13, thereby changing their angle and position to achieve corresponding functional operations. Locking blocks 15 are fixedly connected to the bottom ends of both rotating rods 14. The structure of the locking blocks 15 matches the fixing teeth 16, enabling them to cooperate and achieve a locking function.
[0038] Another limiting block 13 has two fixing teeth 16 externally fixedly connected. The two fixing teeth 16 are slidably connected to the inside of two locking blocks 15. Through the engagement of the locking blocks 15 and the fixing teeth 16, the relative positions of the two rotating rods 12 and the limiting block 13 can be firmly fixed, making the clamping of the gas delivery pipe more stable and reliable. The main body 1 has two gas delivery ports 11 externally fixedly connected. The gas delivery ports 11 are the key parts for oxygen output and gas delivery pipe connection. Oxygen enters the gas delivery pipe through the gas delivery ports 11 and is then delivered to the user. The stability of its position and structure is crucial to the entire oxygen delivery process. The main body 1 has two fans 17 internally fixedly connected. The fans 17 actively draw external air into the oxygen generator, providing a continuous air source for the oxygen production process. Their speed and performance affect the air intake and overall oxygen production efficiency of the oxygen generator. The main body 1 has a slot 10 inside, and the external sliding tooth 5 is slidably connected to the inside of the slot 10. The slot 10 provides accurate positioning and fixed position for the sliding tooth 5, ensuring that the sliding tooth 5 can stably fix the vent plate 2 to the main body 1 in the corresponding state.
[0039] Working principle: When the operator needs to use the oxygen generator to produce oxygen, the gas delivery pipe is connected to the gas delivery port 11. To prevent the connection from coming loose, the two rotating rods 12 can be rotated to clamp and limit the gas delivery pipe. After adjustment, the rotating rod 14 outside one of the limiting blocks 13 can be rotated, causing the inside of the locking block 15 to slide into the fixing tooth 16 outside the other limiting block 13. This fixes the positions of the two rotating rods 12 and the limiting blocks 13, thus securing the gas delivery pipe and preventing the connection from breaking during use, ensuring the stability of oxygen delivery.
[0040] After prolonged use, the oxygen concentrator requires cleaning of the filter 3 and the sterilization layer 4, or replacement of those parts. This can be achieved by rotating the control lever 9 and pulling the sliding block 8, causing the sliding teeth 5 to slide out of the slot 10. This removes the fixation between the ventilation plate 2 and the main body 1, allowing the filter 3 and sterilization layer 4 to be removed for cleaning and replacement. After cleaning, the ventilation plate 2 is pushed back into the main body 1. During this process, the sliding teeth 5 compress the telescopic spring 7, causing them to slide into the ventilation plate 2. When the ventilation plate 2 is fully inserted into the main body 1, the accumulated elastic potential energy of the telescopic spring 7 pushes the sliding teeth 5 into the slot 10, completing the fixing operation and ensuring the sterilization effect of the fan 17 when drawing in external air. The quick opening and closing operation facilitates the overall cleaning and replacement of the sterilization components, improving maintenance efficiency.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
