Description

Technical Field

[0001] This utility model belongs to the field of diffusion oxygen generator technology, specifically relating to an integrated structure of a diffusion oxygen generator filter box. Background Technology

[0002] A diffusion oxygen generator is an indoor integrated oxygen supply device based on molecular sieve pressure swing adsorption (PSA) technology. It adsorbs nitrogen from the air using molecular sieves, separating it into high-purity oxygen. No external oxygen cylinder is needed, and it can continuously produce oxygen-enriched air. The device evenly diffuses the oxygen-enriched air throughout the space via built-in air ducts or diffusers, covering scenarios such as homes, hospital wards, and high-altitude residences. It can meet the oxygen needs of multiple people simultaneously, eliminating the need for consumables such as nasal cannulas, making it convenient to use. It features quiet operation, intelligent oxygen control, and stable output, making it suitable for daily oxygen therapy for people with chronic hypoxia, as well as meeting the oxygen supplementation needs of healthy individuals. It provides a safe and uniform oxygen-enriched atmosphere indoors, improving the body's hypoxic state.

[0003] Existing diffusion oxygen generators mostly use traditional installation methods for their internal filter boxes, such as bolt fastening and snap-fit. Disassembly and assembly require additional tools like screwdrivers and wrenches, and involve individually removing or tightening multiple fasteners. Some structures even require disassembling the outer casing first, making the process cumbersome and complex. This method is not only time-consuming and labor-intensive, but also inefficient, causing inconvenience for daily maintenance and filter replacement. Furthermore, the fasteners are often designed for single-point or localized stress, resulting in uneven stress on the filter box and poor connection stability. Utility Model Content

[0009] In a preferred embodiment, the limiting component includes a sealing groove formed in the inner wall of the filter chamber, a sealing plate slidably connected inside the sealing groove, and a receiving groove formed on the side of the sealing plate near the filter screen.

[0010] In a preferred embodiment, a pressing plate is slidably connected inside the storage slot, and a helical spring is fixedly connected between the pressing plate and the storage slot; an anti-slip groove is provided on the other side of the sealing plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a screw-driven structure with a knob and threaded rod, combined with the guiding and limiting functions of a transmission block, a limiting slider, and a limiting groove, to achieve precise extension and retraction of the telescopic rod. The filter housing can be assembled and disassembled without additional tools, making operation convenient and efficient.

[0015] The present invention will be further described below with reference to the embodiments.

[0016] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0017] Please see Figures 1 to 6 This utility model provides an integrated structure for a diffusion oxygen generator filter box, including a body 1, which is a conventional and publicly available diffusion oxygen generator body. A placement cavity 2 is provided on the side of the body 1, and a filter box 3 is installed inside the placement cavity 2. A fixing component is provided inside the filter box 3, including telescopic grooves 301 arranged in a circular array on the inner right side wall of the filter box 3. Telescopic rods 302 are slidably connected inside the telescopic grooves 301. The telescopic rods 302 are inserted into positioning holes 308 to achieve stable installation of the filter box 3. A limit groove 303 is provided at one end of the telescopic rods 302 that is close to each other, and a transmission block is slidably connected at the other end of the telescopic rods 302 that is close to each other. 304. The transmission block 304 is trapezoidal and can push the telescopic rod 302 to extend or retract during movement. Limiting sliders 305 are fixedly connected around the transmission block 304. A threaded rod 306 is rotatably connected to the side of the transmission block 304. The threaded rod 306 can provide driving force during rotation. The end of the threaded rod 306 away from the transmission block 304 passes through the inner wall of the right side of the filter box 3 and is threadedly connected to the filter box 3. A knob 307 is fixedly connected to the end of the threaded rod 306 away from the transmission block 304. A positioning hole 308 is opened on the inner wall of the placement cavity 2. The positioning hole 308 is adapted to the telescopic rod 302. The limiting slider 305 is slidably connected inside the limiting groove 303.

[0018] When the filter housing 3 needs to be fixed in the placement cavity 2 of the body 1, the knob 307 is turned to drive the threaded rod 306 to rotate. Since the threaded rod 306 is threadedly connected to the inner wall of the right side of the filter housing 3, the rotating threaded rod 306 will push the transmission block 304 towards the inside of the placement cavity 2. When the transmission block 304 moves, the limiting sliders 305 around it will slide in the limiting grooves 303 of the telescopic rod 302, thereby driving the telescopic rods 302, which are distributed in a circumferential array, to extend outward along the telescopic grooves 301. Finally, the end of the telescopic rod 302 is inserted into the positioning hole 308 opened in the inner wall of the placement cavity 2, thus fixing the filter housing 3. When the filter housing 3 needs to be disassembled, the knob 307 is turned in the opposite direction. The threaded rod 306 drives the transmission block 304 to move back. The telescopic rod 302 retracts along the telescopic grooves 301 under the cooperation of the limiting sliders 305 and the limiting grooves 303, and disengages from the positioning hole 308, so that the filter housing 3 can be taken out of the placement cavity 2.

[0019] This utility model utilizes the threaded transmission structure of the knob 307 and threaded rod 306, combined with the guiding and limiting functions of the transmission block 304, the limiting slider 305, and the limiting groove 303, to achieve precise extension and retraction of the telescopic rod 302. The filter housing 3 can be assembled and disassembled without additional tools, making operation convenient and efficient. The circumferentially distributed telescopic rods 302 are matched with the positioning holes 308, ensuring uniform force distribution on the filter housing 3 within the placement cavity 2, resulting in a strong and secure connection. This prevents displacement of the filter housing 3 due to vibration during use. Simultaneously, the self-locking property of the threaded transmission ensures the stability of the fixed state, enhancing the overall structural reliability.

[0020] Specifically, such as Figure 3 and Figure 4 As shown, the filter housing 3 has a filter chamber 4 inside, an air inlet 10 on the right side of the filter chamber 4, and an exhaust port on the side of the filter chamber 4 away from the air inlet 10, which is connected to the main body 1. A grille 11 is fixedly connected inside the air inlet 10, which can block larger impurities in the air. A mounting base 5 is fixedly installed inside the filter chamber 4, and a mounting groove 6 is opened inside the mounting base 5. A filter screen 7 is fixedly installed inside the mounting groove 6 by a limiting component. The filter screen 7 can filter out fine particles in the air.

[0021] When the diffusion oxygen generator is working, the air to be filtered enters the filter chamber 4 from the air inlet 10 on the right side of the filter housing 3. The grille 11 inside the air inlet 10 will first block and filter large particles such as dust and hair in the airflow. The air after pre-treatment by the grille 11 continues to flow into the filter chamber 4 and passes through the filter screen 7 fixed in the mounting groove 6 of the mounting base 5. The filter screen 7 performs deep filtration of fine impurities in the air and finally provides clean air to the oxygen generator through the exhaust port. The mounting groove 6 of the mounting base 5 plays a radial positioning role for the filter screen 7 to prevent the filter screen 7 from shifting under the impact of airflow.

[0022] In this invention, the grille 11 enables air pretreatment, effectively blocking large particles from entering the filter 7, preventing frequent replacement of the filter 7 due to rapid clogging, and extending the service life of the filter 7. The mounting groove 6 of the mounting base 5 provides a stable mounting reference for the filter 7, ensuring that the filter 7 is fixed in position within the filter chamber 4, guaranteeing that the airflow can pass through the filter 7 comprehensively and evenly, thus improving filtration efficiency. The through-flow structure between the air inlet 10 and the filter chamber 4 ensures a smooth airflow path and reduces air intake resistance. At the same time, the graded filtration design of the grille 11 and the filter 7 enables gradual purification from coarse filtration to fine filtration, improving the cleanliness of the intake air and providing a high-quality air source for the subsequent oxygen production process of the oxygen concentrator.

[0023] Specifically, such as Figure 4 and Figure 5 As shown, the limiting component includes a sealing groove 8 formed in the inner wall of the filter chamber 4. A sealing plate 801 is slidably connected inside the sealing groove 8. A storage groove 802 is formed on the side of the sealing plate 801 near the filter screen 7. A pressing plate 803 is slidably connected inside the storage groove 802. A coil spring 804 is fixedly connected between the pressing plate 803 and the storage groove 802. An anti-slip groove 9 is formed on the other side of the sealing plate 801. The anti-slip groove 9 can increase the friction between the sealing plate 801 and the user's hand, thereby making it easier for the staff to remove the sealing plate 801.

[0024] When installing the filter screen 7, the sealing plate 801 is pushed to slide along the sealing groove 8 on the inner wall of the filter chamber 4 towards the filter screen 7 until the side of the sealing plate 801 close to the filter screen 7 is in contact with the side of the filter screen 7. At this time, the pressing plate 803 in the receiving groove 802 is pressed tightly against the end face of the filter screen 7 under the elastic force of the coil spring 804. The elastic deformation of the coil spring 804 can adapt to slight dimensional errors during the installation of the filter screen 7. At the same time, the sealing plate 801 cooperates with the sealing groove 8 on the inner wall of the filter chamber 4 to form a circumferential sealing structure for the filter screen 7, preventing unfiltered air from leaking from the gap between the filter screen 7 and the mounting groove 6.

[0025] In this invention, the cooperation between the sealing plate 801 and the sealing groove 8 achieves circumferential sealing after the filter screen 7 is installed. Combined with the elastic compression action of the extrusion plate 803 and the spiral spring 804, it not only avoids filtration failure caused by air leakage, but also forms a flexible fixation for the filter screen 7 through the elastic buffer of the spiral spring 804, preventing damage to the filter screen 7 caused by rigid fixation. The anti-slip groove 9 provides a convenient force application point for pushing the sealing plate 801, improving the ease of operation. At the same time, the elastic fixing structure makes the filter screen 7 more adaptable to installation, and can be compatible with filter screens 7 with slight dimensional deviations, reducing the installation accuracy requirements and further improving the disassembly and assembly efficiency and the stability of use of the filter screen 7.

[0026] Working principle and usage process of this utility model: In use, the filter housing 3 is first placed into the placement cavity 2 of the machine body 1. Rotating the knob 307 drives the threaded rod 306 to rotate. Because the threaded rod 306 is threadedly connected to the inner wall of the right side of the filter housing 3, the rotating threaded rod 306 pushes the transmission block 304 into the placement cavity 2. When the transmission block 304 moves, its surrounding limiting sliders 305 slide within the limiting grooves 303 of the telescopic rod 302, thereby driving the telescopic rods 302, which are arranged in a circular array, along the telescopic grooves 303. 1. Extend outwards so that the end of the telescopic rod 302 is inserted into the positioning hole 308 on the inner wall of the placement cavity 2 to fix the filter box 3; when installing the filter screen 7, push the sealing plate 801 to slide along the sealing groove 8 on the inner wall of the filter cavity 4 towards the filter screen 7 until the sealing plate 801 is in contact with the side of the filter screen 7, and the squeezing plate 803 in the receiving groove 802 presses tightly against the end face of the filter screen 7 under the elastic force of the spiral spring 804, and the sealing plate 801 and the sealing groove 8 cooperate to form a circumferential seal; When the diffusion oxygen generator is working, the air to be filtered enters from the air inlet 10 on the right side of the filter box 3. The grille 11 inside the air inlet 10 first blocks large particles of impurities. The pre-treated air enters the filter chamber 4 and is deeply filtered by the filter screen 7 fixed in the mounting groove 6 of the mounting base 5. Finally, it is introduced into the machine body 1 through the exhaust port. When disassembly and maintenance are required, the knob 307 is turned in the opposite direction. The threaded rod 306 drives the transmission block 304 to move back. The telescopic rod 302 retracts along the telescopic groove 301 and disengages from the positioning hole 308 under the cooperation of the limit slider 305 and the limit groove 303. The filter box 3 can then be removed. The sealing plate 801 can then be moved through the anti-slip groove 9 to replace or clean the filter screen 7.
