Description

Technical Field

[0001] This invention relates to the field of air purification and filtration technology, and in particular to a high-pressure oxygen chamber compressed air purification and filtration device. Background Technology

[0002] In today's sophisticated and demanding medical environments, hyperbaric oxygen chambers, as a specialized treatment device, are widely used in the clinical treatment of various diseases, including carbon monoxide poisoning, gas gangrene, bedsores, and hypoxic-ischemic encephalopathy. Their core treatment principle involves allowing patients to inhale high concentrations of pure oxygen in a sealed environment at above atmospheric pressure, significantly increasing the dissolved oxygen content in the blood, thereby rapidly improving the hypoxic state of tissues and organs and promoting damage repair and functional recovery. This treatment process places extremely stringent requirements on the purity and cleanliness of the ambient air. Any minute impurities or harmful gases can interfere with the treatment effect or even pose safety risks. Therefore, hyperbaric oxygen chambers must be used in conjunction with dedicated compressed air purification devices, using multi-stage filtration to remove solid particles, oil mist, moisture, and harmful gases from the air, ensuring that the air entering the chamber meets medical-grade cleanliness standards.

[0003] For hyperbaric oxygen chambers, the performance of the air purification device directly determines the safety and effectiveness of the treatment. It not only needs extremely high filtration accuracy but also requires long-term operational stability and uniform gas flow. Currently available air purification technologies, such as ordinary filters and electrostatic precipitators, can remove some impurities and improve air quality in conventional settings, but they often have significant shortcomings when facing the specific needs of hyperbaric oxygen chambers.

[0004] In hyperbaric oxygen therapy, the cleanliness of compressed air directly affects the safety and efficacy of the treatment. However, traditional purification and filtration devices have significant shortcomings. They often employ fixed filtration structures, which easily create airflow dead zones within the device, leading to impurities accumulating on the surface of the filter components. Furthermore, they lack efficient flow distribution designs, resulting in a significant decrease in filtration accuracy when local airflow pressure is too high. This means that the air entering the hyperbaric oxygen chamber may contain residual solid impurities, affecting not only the chamber environment but also potentially irritating the patient's respiratory tract, making it difficult to meet the stringent requirements for air source cleanliness in hyperbaric oxygen therapy.

[0005] Traditional devices also suffer from poor continuous filtration capacity and unstable drive, limiting their suitability for continuous operation in hyperbaric oxygen chambers. Most devices lack automatic dust removal, requiring frequent shutdowns for manual cleaning of the filter components, interrupting the gas supply and disrupting the treatment process. Some devices with drive mechanisms suffer from design flaws in the meshing mechanism, resulting in low precision in the movement of the filter components, prone to jamming, and causing fluctuations in filtration efficiency. Hyperbaric oxygen chambers require a stable 24-hour gas supply; these shortcomings of traditional devices reduce treatment reliability, necessitating optimization and upgrades to meet actual treatment needs. Summary of the Invention

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. In this invention, the basic filtration effect is significant and adaptable to the purification requirements of hyperbaric oxygen chambers: the filter cartridge provides a sealed space, compressed air enters through the air inlet pipe, is temporarily stored and diverted through the two elliptical through holes in the chassis, and then flows to the dust removal hole through the trapezoidal slot of the dust removal cylinder; the design of the dust removal hole with a funnel-shaped outer port, a straight hole middle section and a conical inner port effectively intercepts impurities, and the purified air flows to the exhaust pipe through the elliptical air hole and the elliptical through hole in the top plate, ensuring the initial cleanliness of the air entering the hyperbaric oxygen chamber;

[0022] 2. In this invention, the automatic dust removal mechanism ensures continuous filtration, which is suitable for the operation of a hyperbaric oxygen chamber: the servo motor drives the drive shaft, which drives the gear disk and drive gear to rotate. The gear disk meshes with the fixed gear to make the fixed sleeve rotate, driving the dust collector to move. The drive gear meshes with the driven gear to make the driven shaft rotate, which drives the dust collector roller and the nylon dust collector bristles to clean the outer surface of the dust collector in real time, preventing the dust collector holes from being blocked and avoiding the hyperbaric oxygen chamber's air supply being affected by the accumulation of impurities.

[0023] 3. In this invention, the meshing mechanism is optimized to achieve precise drive, meeting the stable air supply requirements of the hyperbaric oxygen chamber: the driven bevel gear, the fixed bevel gear, the eccentric pin shaft and the annular groove cooperate, and the elliptical plate slides in the U-shaped slide, so that the dust collector can accurately complete the combined motion of lifting and rotating; together with the dust removal brush cleaning, the dust removal holes are kept clear, so as to continuously and stably deliver clean compressed air to the hyperbaric oxygen chamber and improve the reliability of purification filtration;

[0024] In summary, this invention, through the synergistic effect of basic filtration, automatic dust removal, and precise drive, optimizes all aspects from impurity interception and anti-clogging to motion control, meeting the high requirements of hyperbaric oxygen chambers for compressed air purification, ensuring air quality inside the chamber, and providing stable air source support for hyperbaric oxygen therapy.

Detailed Implementation

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] Example 1: This example provides a compressed air purification and filtration device for a hyperbaric oxygen chamber. See [link / reference]. Figures 1 to 8 Specifically, the filter cartridge 100 serves as the outer shell of the entire purification and filtration device, providing an installation carrier and sealing space for all internal components, enabling the introduction, filtration, and export of compressed air. The filter cartridge 100 has a top plate 200, a fixed plate 300, and a bottom plate 207 fixedly installed sequentially from top to bottom along the axial direction in the middle section. The top plate 200 has an elliptical through-hole 201 that allows purified air between the top plate 200 and the fixed plate 300 to flow into the top of the filter cartridge 100, while also providing a mounting position for the fixed sleeve 400 to be rotatably inserted. The fixed plate 300 has a circular through-hole for the dust collector 301 to be slidably inserted, and a central section for the drive shaft 204 to be rotatably inserted, serving as the core installation carrier for the dust collector 301 and the drive shaft 204. The bottom plate 207 has an elliptical through-hole 208 that allows compressed air to enter the cavity between the fixed plate 300 and the bottom plate 207, while also providing a mounting position for the fixed shaft 406 to be fixedly inserted and a mounting position for the drive shaft 204 to be rotatably inserted.

[0037] The fixed plate 300 has several circularly distributed through holes. A dust collector 301 is slidably inserted into the circular through holes. The trapezoidal slots 302 and dust collection holes 303 on the outer surface of the dust collector 301 cooperate to achieve compressed air dust removal and filtration. The interior can accommodate a fixed sleeve 400 and a fixed shaft 406. A fixed sliding hole 304 is provided in the middle of the top surface of the dust collector 301. The fixed sliding hole 304 allows the fixed sleeve 400 to slide through and provides guidance for the lifting and rotation of the dust collector 301. A through-distributed sealing sliding cylinder 308 is integrally formed in the middle of the bottom surface of the dust collector 301. The sealing sliding cylinder 308 allows the bottom end of the fixed shaft 406 to slide through and ensure a seal between the dust collector 301 and the fixed shaft 406, preventing unfiltered air from entering the dust collector 301.

[0038] Several through-hole fixed sleeves 400 are rotatably inserted on the top plate 200. The core function of the fixed sleeves 400 is to drive the dust collector 301 to move through the meshing mechanism. The bottom end of the fixed sleeve 400 slides downward through the corresponding fixed sliding hole 304 and extends into the upper middle part of the dust collector 301. A through-hole fixed shaft 406 is rotatably inserted inside the fixed sleeve 400. The core function of the fixed shaft 406 is to provide stable support for the fixed sleeve 400 and the dust collector 301, and at the same time provide a fixed mounting position for the fixed bevel gear 407. The bottom end of the fixed shaft 406 slides downward through the corresponding sealing slide cylinder 308 and is fixedly inserted on the base plate 207. The fixed sleeve 400 is provided with a meshing mechanism for driving the dust collector 301 to achieve a combined lifting and rotating motion. The core function of the meshing mechanism is to drive the dust collector 301 to achieve a combined lifting and rotating motion.

[0039] It should be noted that: in this embodiment, as Figure 1 , Figure 4 and Figure 8 As shown, the bottom of the filter cartridge 100 is fixed with a through-distributed air inlet pipe 101, which is the only channel for the compressed air generated by the hyperbaric oxygen chamber to enter the filter cartridge 100. The top of the filter cartridge 100 is fixed with a through-distributed exhaust pipe 102, which is used to discharge the purified air and transport it to the next process.

[0040] The top plate 200 has several circularly distributed elliptical through holes 201, the axes of which are parallel to the axis of the filter cartridge 100. Their primary function is to allow purified air between the top plate 200 and the fixed plate 300 to flow upwards into the top of the filter cartridge 100. The bottom plate 207 has several circularly distributed elliptical through holes 208, the axes of which are parallel to the axis of the filter cartridge 100. These allow compressed air from the bottom of the filter cartridge 100 to enter the fixed plate. The cavity between the filter cylinder 300 and the chassis 207 allows for temporary storage and uniform distribution of airflow. Several elliptical air holes 306 are arranged in a circular pattern on the top surface of the dust collector 301. The axis of the elliptical air holes 306 is parallel to the axis of the filter cylinder 100. They are used to discharge the purified air inside the dust collector 301 upward into the cavity between the top chassis 200 and the fixed chassis 300. The axes of the elliptical through hole 1 201, the elliptical through hole 208 and the elliptical air holes 306 are all parallel to the axis of the filter cylinder 100.

[0041] The lower half of the outer surface of the dust collector 301 is uniformly provided with several trapezoidal slots 302 arranged in a circular array along the circumference. The trapezoidal slots 302 provide a channel for compressed air to flow to the dust collection holes 303, while increasing the airflow contact area. Several dust collection holes 303 are provided on the two side walls of the trapezoidal slots 302. The outer port of the dust collection hole 303 is designed as an outward-opening trumpet-shaped structure, the middle section is designed as a straight hole-shaped structure, and the inner port is designed as an inward-contracting conical structure. The expansion angle of the trumpet-shaped structure is 30°-45°, which facilitates the rapid introduction of airflow. The middle straight hole-shaped structure ensures stable airflow. The contraction angle of the conical structure is 20°-30°, which can enhance the airflow impact force and avoid impurities clogging the air. The dust collection holes 303 are used to intercept solid impurities in the compressed air and only allow purified air to enter the interior of the dust collector 301.

[0042] The working principle of this embodiment is as follows: the meshing mechanism drives several dust collector cylinders 301 to achieve a composite motion of lifting and rotating, which can break the airflow dead zone of compressed air in the filtration process, avoid impurities from accumulating on the surface of the dust collector cylinders 301, lay the foundation for subsequent high-efficiency filtration, and ensure stable filtration efficiency.

[0043] When the hyperbaric oxygen chamber is operating normally and generates compressed air, the compressed air is discharged into the bottom of the filter cartridge 100 through the air inlet pipe 101. It then smoothly enters the cavity formed between the fixed plate 300 and the base plate 207 through several elliptical through holes 208, which can realize the temporary storage and uniform distribution of airflow and avoid excessive local airflow pressure from affecting the filtration effect.

[0044] Then, the compressed air flows along the trapezoidal slot 302 into the dust removal hole 303. When the compressed air passes through the dust removal hole 303, the solid impurities in it will be intercepted by the hole wall. Only the purified airflow can pass through the dust removal hole 303 into the dust removal cylinder 301 to complete the core dust removal and filtration step.

[0045] The purified compressed air entering the dust collector 301 is discharged upward through the elliptical air hole 306 into the cavity formed between the top plate 200 and the fixed plate 300. It continues to flow upward through several elliptical through holes 201 into the inner top of the filter cartridge 100. Then, the purified air is discharged into the next operation step along the exhaust pipe 102, completing the entire purification and filtration process.

[0046] The beneficial effects of this embodiment are that the basic filtration effect is significant and it is suitable for the purification requirements of hyperbaric oxygen chambers: the filter cartridge 100 provides a sealed space, and compressed air enters through the air inlet pipe 101, is temporarily stored and diverted through the elliptical through hole 208 of the chassis 207, and then flows to the dust removal hole 303 through the trapezoidal slot 302 of the dust removal cartridge 301; the dust removal hole 303 is designed with a funnel-shaped outer port, a straight hole middle section and a conical inner port, which effectively intercepts impurities. The purified air flows to the exhaust pipe 102 through the elliptical air hole 306 and the elliptical through hole 201 of the top plate 200, ensuring the initial cleanliness of the air entering the hyperbaric oxygen chamber.

[0047] Example 2: Based on Example 1, this example adds an automatic dust removal mechanism consisting of a servo motor 203, a drive shaft 204, a gear disk 205, a drive gear 206, a driven shaft 209, a dust removal roller 211, and dust removal brush bristles 212. This optimizes the driving method of the dust removal cylinder 301 through gear transmission and solves the problem of impurities accumulating on the outer surface of the dust removal cylinder 301, affecting the filtration efficiency. It also includes:

[0048] In the specific implementation process, such as Figure 3 and Figure 4 As shown, a drive shaft 204 is rotatably inserted in the middle of the fixed disk 300. The drive shaft 204 can drive the gear disk 205 and the drive gear 206 to rotate synchronously. A U-shaped horizontal plate 202 with the opening facing downward is fixed on the top surface of the top disk 200. The U-shaped horizontal plate 202 is used to fix the servo motor 203 and provide a stable mounting carrier for the servo motor 203. The servo motor 203 with the output end facing downward is fixedly installed in the middle of the U-shaped horizontal plate 202. The motor shaft end of the servo motor 203 is fixedly connected to the top end of the drive shaft 204 through a coupling to provide power for the entire drive system. The bottom end of the drive shaft 204 is rotatably inserted in the middle of the chassis 207. The core function of the drive shaft 204 is to transmit the power of the servo motor 203 and drive the gear disk 205 and the drive gear 206 to rotate synchronously.

[0049] Each fixed sleeve 400 has a fixed gear 401 fixedly fitted at its top end. The fixed gear 401 meshes with the gear disk 205 for transmission, receives the power transmitted by the drive shaft 204 and drives the fixed sleeve 400 to rotate around its own axis. The drive shaft 204 has a gear disk 205 fixedly fitted at its top end. The gear disk 205 meshes with several fixed gears 401 in sequence for transmission. The module of the gear disk 205 is consistent with the module of the fixed gears 401. The gear disk 205 transmits the power of the drive shaft 204 to the fixed sleeve 400, driving the fixed sleeve 400 to rotate.

[0050] A number of driven shafts 209 are rotatably inserted into the center of the bottom surface of the fixed disk 300, which are evenly distributed in a ring around the drive shaft 204. The core function of the driven shafts 209 is to transmit the power of the drive gear 206 to drive the dust removal roller 211 to rotate. The dust removal roller 211 is fixedly sleeved on the driven shaft 209. The dust removal roller 211 rotates with the driven shaft 209, which drives the dust removal bristles 212 to rotate synchronously, providing the dust removal bristles 212 with a mounting carrier and rotational power. A number of evenly distributed dust removal bristles 212 are adhered to the outer surface of the dust removal roller 211. The dust removal bristles 212 are all attached to the outer surface of the corresponding dust removal cylinder 301. The material of the dust removal bristles 212 is nylon wear-resistant material. The core function of the dust removal bristles 212 is to clean the impurities on the outer surface of the dust removal cylinder 301 in real time and prevent the dust removal holes 303 from being blocked.

[0051] Each driven shaft 209 has a driven gear 210 fixedly sleeved on its upper middle part. The driven gear 210 receives the power from the drive gear 206 and drives the driven shaft 209 to rotate around its own axis. The driven gear 210 meshes with the drive gear 206 for transmission. The drive shaft 204 has a drive gear 206 fixedly sleeved on its middle part. The drive gear 206 meshes with several driven gears 210 in sequence for transmission. The number of teeth of the drive gear 206 and the number of teeth of the driven gear 210 meet the transmission ratio requirements. The drive gear 206 transmits the power of the drive shaft 204 to the driven shaft 209, driving the driven shaft 209 to rotate.

[0052] The working principle of this embodiment is as follows: the motor shaft of the servo motor 203 drives the drive shaft 204, gear disk 205, and drive gear 206 to rotate synchronously through the coupling, thus completing the initial transmission of power;

[0053] The gear disk 205 meshes with several fixed gears 401 in sequence, driving the fixed sleeve 400 to rotate around its own axis. Then, through the meshing mechanism on the fixed sleeve 400, it drives several dust collectors 301 to achieve a compound motion of lifting and rotating, laying the foundation for subsequent airflow filtration. Moreover, the transmission method is more stable, avoiding the dust collectors 301 from getting stuck.

[0054] The drive gear 206 meshes with several driven gears 210 in sequence to drive the driven shaft 209 to rotate around its own axis. When the driven shaft 209 rotates, the dust removal roller 211 and the dust removal brush 212 rotate synchronously.

[0055] As the dust removal brush 212 rotates with the dust removal roller 211, the rotating dust removal brush 212 will clean the outer surface of the dust removal cylinder 301 in real time, thoroughly removing the impurities attached to the outer surface of the dust removal cylinder 301, preventing impurities from clogging the dust removal holes 303, ensuring that the dust removal holes 303 always remain unobstructed, and avoiding the problem of increased airflow resistance and decreased filtration efficiency due to the accumulation of impurities.

[0056] The beneficial effect of this embodiment is that the automatic dust removal mechanism ensures continuous filtration, which is suitable for the operation of the hyperbaric oxygen chamber: the servo motor 203 drives the drive shaft 204, which drives the gear disk 205 and the drive gear 206 to rotate. The gear disk 205 meshes with the fixed gear 401 to make the fixed sleeve 400 rotate, which drives the dust collector 301 to move. The drive gear 206 meshes with the driven gear 210 to make the driven shaft 209 rotate, which drives the dust collector roller 211 and the nylon dust collector bristles 212 to clean the outer surface of the dust collector 301 in real time, prevent the dust collector holes 303 from being blocked, and avoid the hyperbaric oxygen chamber air supply being affected by the accumulation of impurities.

[0057] Example 3: Based on Example 2, this example optimizes the meshing mechanism into a combination structure of driven bevel gear 404, fixed bevel gear 407, eccentric pin 405, and annular groove 307. This solves the problems of inaccurate composite motion drive and unstable limit in the dust collector 301 in Example 2, achieving precise and controllable lifting and rotating motion. It also includes:

[0058] In the specific implementation process, such as Figure 6 and Figure 7 As shown, a U-shaped groove 305 is provided on the fixed sliding hole 304. The U-shaped groove 305 allows the elliptical locking plate 402 of the fixed sleeve 400 to slide and engage, ensuring that the dust collector 301 rotates stably with the fixed sleeve 400. An elliptical locking plate 402 is integrally formed and fixed on the outer wall of the fixed sleeve 400. The elliptical locking plate 402 slides and engages in the U-shaped groove 305 of the dust collector 301, ensuring that the dust collector 301 rotates stably with the fixed sleeve 400, while also adapting to the lifting and lowering movement of the dust collector 301. The fit clearance between the elliptical locking plate 402 and the U-shaped groove 305 is controlled within the range of 0.05mm to 0.1mm.

[0059] The meshing mechanism includes a driven bevel gear 404 and a fixed bevel gear 407. An annular groove 307 is provided inside the dust collector 301. A horizontal shaft 403 is radially fixedly inserted into the bottom of the fixed sleeve 400. The horizontal shaft 403 provides a rotatable mounting position for the driven bevel gear 404, ensuring that the driven bevel gear 404 can rotate on its own axis while rotating with the fixed sleeve 400. The driven bevel gear 404 is rotatably sleeved on the outer end of the horizontal shaft 403. When the driven bevel gear 404 rotates with the fixed sleeve 400, it rotates around the fixed bevel gear 407. An eccentric pin 405 on the end face provides... Axial driving force is the core power transmission component of the meshing mechanism. An eccentric pin 405 is integrally formed and fixed on the end face of the driven bevel gear 404. The outer end of the eccentric pin 405 is slidably engaged in the annular groove 307 of the dust collector 301. As the driven bevel gear 404 rotates, it makes eccentric circular motion. The eccentric motion is converted into the lifting power of the dust collector 301 through the annular groove 307. The annular groove 307 allows the eccentric pin 405 of the driven bevel gear 404 in the meshing mechanism to slide and engage, converting the eccentric motion of the eccentric pin 405 into the axial driving force of the dust collector 301.

[0060] A fixed bevel gear 407 is fixedly sleeved in the middle of the fixed shaft 406. The fixed bevel gear 407 meshes with the driven bevel gear 404 for transmission. Its core function is to provide a fixed meshing reference for the driven bevel gear 404, so that the driven bevel gear 404 rotates on its own axis when it rotates with the fixed sleeve 400. The driven bevel gear 404 rotates around the fixed bevel gear 407 and meshes with the fixed bevel gear 407 for transmission. The cone angle of the driven bevel gear 404 matches the cone angle of the fixed bevel gear 407. When the driven bevel gear 404 rotates with the fixed sleeve 400, it rotates on its own axis around the fixed bevel gear 407, driving the eccentric pin shaft 405 to perform eccentric circular motion.

[0061] The working principle of this embodiment is as follows: the motor shaft of the servo motor 203 drives the drive shaft 204, gear disk 205, and drive gear 206 to rotate synchronously through the coupling. The gear disk 205 meshes with and drives the fixed gear 401 and the fixed sleeve 400 to rotate.

[0062] When the fixed sleeve 400 rotates, the elliptical plate 402 is slidably engaged in the U-shaped slide groove 305, which synchronously drives the dust collector 301 and the sealing slide 308 to rotate stably along the fixed shaft 406, providing a power basis for uniform filtration of compressed air when it passes through the dust collector hole 303.

[0063] While the fixed sleeve 400 drives the dust collector 301 to rotate, the driven bevel gear 404 will rotate on its own axis while rotating around the fixed bevel gear 407, and the eccentric pin 405 will make eccentric circular motion with the rotation of the driven bevel gear 404.

[0064] The eccentric motion of the eccentric pin 405 can be converted into an axial driving force on the dust collector 301 through the annular groove 307, which drives the dust collector 301 and the sealing slide 308 to reciprocate up and down along the fixed shaft 406. At the same time, the elliptical plate 402 will slide adaptively along the U-shaped slide 305, ultimately realizing the precise compound motion of the dust collector 301 rotating and lifting.

[0065] During the compound motion of the dust collector 301, the rotating dust collector bristles 212 always adhere to the outer surface of the dust collector 301, especially cleaning the trapezoidal slot 302 area in real time, thoroughly removing impurities attached to the outer surface of the dust collector holes 303 on both sides of the trapezoidal slot 302, avoiding blockage of the dust collector holes 303, and ensuring smooth airflow.

[0066] The beneficial effect of this embodiment is that the meshing mechanism is optimized to achieve precise drive, which meets the stable air supply requirements of the hyperbaric oxygen chamber: the driven bevel gear 404, the fixed bevel gear 407, the eccentric pin 405 and the annular groove 307 cooperate, and the elliptical plate 402 slides in the U-shaped slide groove 305, so that the dust collector 301 can accurately complete the combined motion of lifting and rotating; in conjunction with the dust removal brush 212 cleaning, the dust removal hole 303 is kept unobstructed, so as to continuously and stably deliver clean compressed air to the hyperbaric oxygen chamber and improve the reliability of purification filtration.

[0067] This invention optimizes all aspects of hyperbaric oxygen chambers, from impurity interception and anti-clogging to motion control, through the synergistic effect of basic filtration, automatic dust removal, and precise drive. It meets the high requirements of hyperbaric oxygen chambers for compressed air purification, ensures air quality inside the chamber, and provides a stable air source for hyperbaric oxygen therapy.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
