It is not very active at room temperature and does not easily react with many substances. Usually, high-purity oxygen is required in the fields of medical treatment, industry, food processing, aquaculture, etc.
[0003] A Chinese patent discloses an impurity removal and purification device for ultra-pure oxygen production (authorization announcement number CN214680892U). This patented technology improves the purification effect of oxygen through multiple adsorption and filtration of oxygen. Moreover, through the built-in design, the space utilization rate is improved, and it is also convenient for disassembly and assembly.
[0004] In view of the above and related existing technologies, the inventor believes that the following defects often exist: The existing oxygen purification equipment filters oxygen to obtain high-purity oxygen. During the filtering process, impurities will adhere to the filter element. Therefore, the filter element needs to be replaced regularly. Since the filter element is usually installed inside the equipment through fasteners such as screws, during the disassembly process, technicians need to operate with tools such as screwdrivers and wrenches. However, the internal space of the equipment is relatively narrow, and the use space of the tools is limited. This increases the difficulty and complexity of the operation, and at the same time, it may accidentally touch other components inside the equipment, causing damage to the equipment and affecting the normal operation of the equipment. Summary of the Utility Model
[0005] The technical problem to be solved by the utility model is that in the prior art, the filter element is usually fixed inside the equipment by screws, so tools such as screwdrivers and wrenches are needed during the disassembly process of the filter element. However, the internal space of the equipment is usually small, and other equipment may be accidentally touched when using tools, resulting in damage to the equipment. For this reason, we propose a high-purity oxygen purification device.

[0022] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0023] Reference Figure 1 - Figure 5As shown, the utility model provides a technical solution: a high-purity oxygen purification device, including an outer box 1, a box door 2 is installed on one side of the outer box 1, a controller 3 is installed inside the box door 2, an air inlet pipe 4 is fixedly connected to one side of the outer box 1, a fixed block 5 is fixedly connected to the surface of the air inlet pipe 4, an air compressor 6 is fixedly connected to one end of the air inlet pipe 4, a condenser 7 is installed on one side of the air compressor 6, a heater 8 is installed on one side of the condenser 7, a plurality of exhaust pipes 9 are fixedly connected to one side of the heater 8, and the inside of the fixed block 5 A filter element 10 is slidably connected, a receiving groove 11 is provided on the top of the fixed block 5, a connecting plate 12 is slidably connected inside the receiving groove 11, a limiting rod 13 is fixedly connected to one side of the connecting plate 12, a limiting groove 14 is provided on one side of the filter element 10, an elliptical plate 15 is rotatably connected inside the receiving groove 11, a connecting rod 16 is fixedly connected to the top of the elliptical plate 15, a knob 17 is installed on the top of the connecting rod 16, and one side of the connecting plate 12 is fixedly connected to the other end of two first thrust springs 18 and the inner end of the receiving groove 11. One side is fixedly connected, and the gas enters the air compressor 6 inside the outer box 1 through the air inlet pipe 4. The air is compressed by the air compressor 6 and transmitted to the inside of the condenser 7 for cooling and liquefaction. The liquefied air is transported to the inside of the heater 8 for heating. Since the boiling points of various gases in the air are different, the condenser 7 is controlled to heat the liquid air to different temperatures, so that the oxygen in the air is separated from other gases, and high-purity oxygen can be obtained. When the air passes through the inside of the fixed block 5, the filter element 10 inside the fixed block 5 filters the dust in the air to prevent the dust from entering the equipment behind, resulting in reduced gas purity, and at the same time prevent dust accumulation from clogging the equipment. The filter element 10 needs to be replaced regularly during use of the equipment. By rotating the knob 17, the elliptical plate 15 is driven to rotate, so that the limit of the connecting plate 12 is released. Under the thrust of the first thrust spring 18, the connecting plate 12 is pushed to move, driving the limit rod 13 to disengage from the inside of the limit groove 14, releasing the limit on the filter element 10, so that the user can take out the filter element 10 for replacement.
[0024] Reference Figure 5 As shown, in this embodiment: the interior of the connecting rod 16 is slidably connected with a telescopic rod 19, the top of which is fixedly connected to the bottom of the knob 17, a limiting hole 20 is provided on the top of the fixing block 5, and a limiting block 21 is fixedly connected to the bottom of the knob 17. When the user needs to remove the filter element 10, the knob 17 is pulled to disengage the limiting block 21 from the inside of the limiting hole 20, thereby releasing the limit on the knob 17 and allowing the knob 17 to rotate. Rotating the knob 17 drives the elliptical plate 15 to rotate, thereby releasing the limit on the filter element 10. By installing the limiting block 21 at the bottom of the knob 17, the angle of the knob 17 can be limited to prevent the knob 17 from rotating due to vibration during the operation of the equipment.
[0025] Reference Figure 5As shown, in this embodiment: Limiting sliding grooves 22 are provided on both sides inside the connecting rod 16. Limiting sliders 23 are fixedly connected to both sides of the telescopic rod 19. During the process of the user pulling the knob 17, the limiting sliders 23 on both sides of the telescopic rod 19 move inside the limiting sliding grooves 22 to limit the movement of the telescopic rod 19 and prevent the telescopic rod 19 from disengaging from inside the connecting rod 16.
[0026] Referring to Figure 5 As shown, in this embodiment: A tension spring 24 is fixedly connected to the bottom of the telescopic rod 19, and the bottom end of the tension spring 24 is fixedly connected to the bottom inside the connecting rod 16. By installing the tension spring 24 at the bottom of the telescopic rod 19, a continuous pulling force can be exerted on the telescopic rod 19 to prevent the telescopic rod 19 from moving upward due to the vibration of the equipment during operation.
[0027] Referring to Figure 4 As shown, in this embodiment: First sliding grooves 25 are provided on both sides inside the storage groove 11. First sliders 26 are fixedly connected to both sides of the connecting plate 12. During the process of the user rotating the knob 17 to move the connecting plate 12, the first sliders 26 on both sides of the connecting plate 12 slide inside the first sliding grooves 25 to assist the movement of the connecting plate 12 and prevent the connecting plate 12 from tilting, resulting in stuck movement.
[0028] Referring to Figure 6 As shown, in this embodiment: A placement groove 27 is provided at the bottom inside the fixed block 5. A second thrust spring 28 is fixedly connected to the bottom inside the placement groove 27. The top end of the second thrust spring 28 is fixedly connected to a push rod 29. The surface of the push rod 29 is slidably connected to the inside of the placement groove 27. The top of the push rod 29 is in contact with the bottom of the filter element 10. After the user rotates the knob 17 to release the limit on the filter element 10, the second thrust spring 28 at the bottom of the filter element 10 pushes the push rod 29 upward to push the filter element 10 upward by a certain distance, facilitating the user to take out the filter element 10 for replacement.
[0029] Referring to Figure 6 As shown, in this embodiment: Second sliding grooves 30 are provided on both sides inside the placement groove 27. Second sliders 31 are fixedly connected to both sides of the push rod 29. During the movement of the push rod 29, the second sliders 31 on both sides move inside the second sliding grooves 30 to limit the movement of the push rod 29 and prevent the push rod 29 from disengaging from inside the placement groove 27, resulting in misalignment between the push rod 29 and the placement groove 27 when installing the filter element 10, causing the filter element 10 to be not properly installed.
[0030] Working principle: The gas enters the air compressor 6 inside the outer box 1 through the intake pipe 4. The air compressor 6 compresses the air and transmits it to the inside of the condenser 7 for cooling and liquefaction. The liquefied air is transported to the inside of the heater 8 for heating. Since the boiling points of various gases in the air are different, by controlling the condenser 7 to heat the liquid air to different temperatures, oxygen in the air can be separated from other gases, and high-purity oxygen can be obtained. When the air passes through the inside of the fixed block 5, the filter element 10 inside the fixed block 5 filters the dust in the air to prevent the dust from entering the subsequent equipment, resulting in a decrease in the purity of the gas, and at the same time preventing the equipment from being blocked due to dust accumulation. During the use of the equipment, the filter element 10 needs to be replaced regularly. By rotating the knob 17, the elliptical plate 15 is driven to rotate, so that the limit of the connecting plate 12 is released. Under the thrust of the first thrust spring 18, the connecting plate 12 is pushed to move, driving the limit rod 13 to disengage from the inside of the limit groove 14, releasing the limit on the filter element 10, facilitating the user to take out the filter element 10 for replacement. When the filter element 10 needs to be removed, the knob 17 is pulled to make the limit block 21 disengage from the inside of the limit hole 20, releasing the limit on the knob 17, so that the knob 17 can rotate. Rotating the knob 17 drives the elliptical plate 15 to rotate, releasing the limit on the filter element 10. By installing the limit block 21 at the bottom of the knob 17, the angle of the knob 17 can be limited to prevent the knob 17 from rotating due to the vibration during the operation of the equipment. During the process of pulling the knob 17, the limit sliders 23 on both sides of the telescopic rod 19 move inside the limit chute 22 to limit the movement of the telescopic rod 19 to prevent the telescopic rod 19 from disengaging from the inside of the connecting rod 16. By installing the tension spring 24 at the bottom of the telescopic rod 19, a continuous tension can be applied to the telescopic rod 19 to prevent the telescopic rod 19 from being affected by the vibration of the equipment and moving upward. When rotating the knob 17 to move the connecting plate 12, the first sliders 26 on both sides of the connecting plate 12 slide inside the first chute 25 to assist the movement of the connecting plate 12 and prevent the connecting plate 12 from tilting. After rotating the knob 17 to release the limit on the filter element 10, the second thrust spring 28 at the bottom of the filter element 10 pushes the ejector rod 29 upward, pushing the filter element 10 upward by a certain distance, facilitating the user to take out the filter element 10 for replacement. During the movement of the ejector rod 29, the second sliders 31 on both sides move inside the second chute 30 to limit the movement of the ejector rod 29 to prevent the ejector rod 29 from disengaging from the inside of the placement groove 27, resulting in the inability to align the ejector rod 29 with the placement groove 27 when installing the filter element 10.
[0031] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used 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 recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features.
