Description

Technical Field

[0001] This invention belongs to the field of micro hyperbaric oxygen chamber technology, specifically a pressure chamber body for a micro hyperbaric oxygen chamber. Background Technology

[0002] The pressure chamber of a hyperbaric oxygen chamber is the core component of hyperbaric oxygen therapy equipment. It is usually made of high-strength alloy materials or composite pressure-resistant materials, and has good sealing performance and pressure bearing capacity. It can provide patients with a specific pressure oxygen environment in the chamber, and achieve the treatment of a variety of diseases by increasing blood oxygen partial pressure and improving tissue hypoxia.

[0003] Because the chamber is under sealed pressure, patients inside continuously produce carbon dioxide through respiration. Simultaneously, the equipment releases heat and trace amounts of waste gas during operation. If air replacement is not performed promptly, the oxygen concentration inside the chamber will decrease, and temperature and humidity will become unbalanced, severely impacting the treatment environment and patient comfort. Therefore, all hyperbaric oxygen chambers require a ventilation system. This system introduces external air through an intake channel, filters it to remove dust, particulate matter, and other impurities, and then sends it into the chamber. Simultaneously, it exhausts stale air from the chamber through an exhaust channel, thereby maintaining air cleanliness and parameter stability within the chamber.

[0004] However, during long-term use, the filter media of the filtration equipment will gradually become clogged due to the continuous interception of impurities, resulting in increased airflow resistance. This makes it difficult to stably control the intake and exhaust volume of the ventilation system, directly causing air pressure fluctuations inside the chamber and making it impossible to maintain the stable pressure environment required for treatment. Furthermore, unstable air pressure can also cause discomfort to patients.

[0005] Therefore, the present invention provides a pressure chamber body for a micro hyperbaric oxygen chamber. Summary of the Invention

[0012] The water delivery assembly includes a water delivery cylinder, a piston, a first water pipe, and a second water pipe. The water delivery cylinder is fixedly installed on the top of the processing rod, and the piston is slidably installed inside the water delivery cylinder. The first water pipe and the second water pipe are both installed on the water delivery cylinder.

[0016] The beneficial effects of this invention are as follows: 1. The pressure chamber of the micro hyperbaric oxygen chamber described in this invention allows for the control of a viscous rod sliding downwards to adhere to the filter surface via a translation component. This, combined with a power rod driving a treatment rod to rotate around the filter, ensures complete coverage and adhesion of impurities to the filter surface. Simultaneously, a rotating component, through the meshing of a gear ring and a transmission gear, causes the viscous rod to rotate synchronously during its revolution, ensuring continuous contact between the unadhered surface of the viscous rod and the clean area of ​​the filter. This significantly improves the thoroughness of impurity removal, substantially reduces airflow resistance, ensures stable and controllable intake and exhaust volumes of the ventilation system, avoids pressure fluctuations within the chamber, and guarantees the effectiveness of hyperbaric oxygen therapy and patient comfort.

[0017] 2. The pressure chamber of the micro hyperbaric oxygen chamber of the present invention uses a first arc plate and a second arc plate to rotatably seal the bottom of the mounting shell, thereby enclosing the adhesive rod to form a sealed chamber. The water supply component delivers water to the water chamber through a water ring and a water pipe, and the water enters the sealed chamber through the water outlet to flush the adhesive rod. In conjunction with the rotating component, the adhering impurities are peeled off. The impurities and wastewater are discharged through the through holes and slag discharge structure on the arc plate, which quickly resets the adhesive properties of the adhesive rod, reduces the frequency and cost of equipment downtime maintenance, and ensures the long-term stable function of the cleaning structure, thereby improving the continuity and reliability of the overall operation of the hyperbaric oxygen chamber.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] The pressure chamber of a micro hyperbaric oxygen chamber according to an embodiment of the present invention includes a chamber body 1 and an air duct 2; A filter screen 3 is fixedly installed inside the air duct 2. A treatment rod 6 is rotatably installed on the filter screen 3 via a power rod 5. An installation shell 26 is fixedly installed inside the treatment rod 6. The cross-section of the installation shell 26 is semi-circular. An adhesive rod 25 is movably installed inside the installation shell 26. The processing rod 6 has a rotating assembly inside, which is used to control the rotation of the adhesive rod 25; The processing rod 6 is equipped with a translation component inside, which is used to control the upward or downward sliding of the adhesive rod 25; The power rod 5 is driven by a motor. When the power rod 5 rotates, it can drive the treatment rod 6 to rotate on the surface of the filter screen 3. The bottom of the treatment rod 6 is not in contact with the surface of the filter screen 3, and the mounting shell 26 is also not in contact with the filter screen 3. First, the adhesive rod 25 is controlled by the translation component to slide downward inside the mounting shell 26 until the surface of the adhesive rod 25 is in contact with the surface of the filter screen 3. At this time, when the power rod 5 drives the treatment rod 6 to move, it can simultaneously drive the adhesive rod 25 to rotate around the filter screen 3. The rotating component set at the same time can make the adhesive rod 25 rotate on its own axis while rotating around the circumference. This can make the side of the adhesive rod 25 without dust adhering to it contact the uncleaned part of the filter screen 3 as much as possible, further improving the effect of the adhesive rod 25 in adhering to the dust on the surface of the filter screen 3, reducing the airflow resistance, avoiding the problem of unstable airflow and pressure fluctuations in the chamber 1, which would lead to the inability to maintain the stable pressure required for treatment, thereby ensuring the treatment effect.

[0023] The top of the mounting shell 26 is provided with a water cavity 24, and the inner wall of the mounting shell 26 is provided with a water outlet hole. A first arc plate 31 and a second arc plate 32 with a cavity are rotatably mounted between the mounting shell 26 and the adhesive rod 25. The first arc plate 31 and the second arc plate 32 have through holes near the adhesive rod 25. A water ring 4 is fixedly installed on the top of the air duct 2, and a water delivery assembly is provided on the top of the treatment rod 6 to deliver the water in the water ring 4 to the interior of the water chamber 24.

[0024] First, the first arc plate 31 and the second arc plate 32 are rotated to seal the bottom of the mounting shell 26 and enclose the adhesive rod 25. At this time, water is sent into the water chamber 24 through the water supply component and then enters the sealed chamber formed by the mounting shell 26, the first arc plate 31 and the second arc plate 32 through the water outlet. This washes the surface of the adhesive rod 25. At the same time, the rotating component washes off the dust adhering to the filter screen 3 and discharges it through the through holes on the first arc plate 31 and the second arc plate 32, resetting the adhesiveness of the adhesive rod 25 and further improving the service life of the adhesive rod 25.

[0025] The rotating assembly includes a rotating groove 10, a gear ring 9, a rotating gear 8, a first transmission gear 35, a control column 33, and a connecting assembly. The rotating groove 10 is formed on the inner wall of the air duct 2. The gear ring 9 is fixedly installed inside the rotating groove 10. The control column 33 is fixedly installed on the side wall of the adhesive rod 25. The first transmission gear 35 is rotatably installed inside the mounting housing 26. The control column 33 is connected to the first transmission gear 35 through the connecting assembly. The first transmission gear 35 is fixedly connected to the rotating gear 8.

[0026] When the power rod 5 drives the processing rod 6 to rotate inside the air duct 2, the first transmission gear 35 will drive the rotating gear 8 to move inside the rotating groove 10, and under the action of the gear ring 9, drive the first transmission gear 35 to rotate. Through the connecting assembly, the control column 33 can be driven to rotate at the same time, thereby realizing the rotation of the adhesive rod 25.

[0027] The connecting assembly includes a snap-fit ​​ball 34, a snap-fit ​​block, a groove 43, and a second transmission gear 36. The snap-fit ​​ball 34 is elastically mounted inside the control post 33. The groove 43 is formed on the outer wall of the snap-fit ​​ball 34. The second transmission gear 36 is rotatably mounted inside the mounting housing 26. The first transmission gear 35 meshes with the second transmission gear 36. The snap-fit ​​block is disposed inside the first transmission gear 35 and the second transmission gear 36.

[0028] The locking ball 34 is installed inside the control column 33 by a top-compression spring. The top-compression spring keeps the locking ball 34 in a pop-out tendency. When the locking ball 34 enters the interior of the first transmission gear 35, it will engage with the locking block on the inner wall of the first transmission gear 35. A limit block is set between the locking ball 34 and the control column 33, so that the locking ball 34 can only slide inside the control column 33 and cannot rotate. Therefore, when the locking ball 34 engages with the locking block of the first transmission gear 35, the rotation of the first transmission gear 35 will drive the control column 33 to rotate synchronously. Similarly, when the locking ball 34 engages with the locking block inside the second transmission gear 36, the second transmission gear 36 will also drive the control column 33 to rotate through the locking ball 34.

[0029] A reset spring is provided at the bottom of the control column 33. When the control column 33 drives the locking ball 34 to slide in the direction of the second transmission gear 36, the reset spring will also contract and store elastic potential energy.

[0030] The translation assembly includes a take-up reel 12, a pull rope 30, and a drive motor. The take-up reel 12 is rotatably mounted on the top of the processing rod 6. The control column 33 is fixedly connected to the take-up reel 12 via the pull rope 30. The output shaft of the drive motor is fixedly connected to the take-up reel 12.

[0031] When the drive motor starts, it can drive the winding wheel 12 to wind up the pull rope 30. At this time, the control column 33 drives the locking ball 34 to slide downward. By pressing the locking ball 34, the locking ball 34 is separated from the first transmission gear 35 until the locking ball 34 is engaged with the locking block inside the second transmission gear 36. At this time, the adhesive rod 25 will adhere to the surface of the filter screen 3. At the same time, when the power rod 5 drives the processing rod 6 to rotate, the rotating gear 8 will also drive the second transmission gear 36 to rotate through the first transmission gear 35. Thus, the adhesive rod 25 can rotate around the surface of the filter screen 3 while also rotating on its own axis, thereby improving the cleaning effect on the filter screen 3.

[0032] A positioning ring is rotatably mounted on the outer wall of the control column 33. A first positioning block 41 and a second positioning block 42 are fixedly mounted on the positioning ring. A first sliding rod 38 is fixedly mounted on the first arc plate 31. The first sliding rod 38 is fixedly connected to the first positioning block 41 through a first connecting rope 40. A second sliding rod 37 is fixedly mounted on the second arc plate 32. The second sliding rod 37 is fixedly connected to the second positioning block 42 through a second connecting rope 39. The first sliding rod 38 and the second sliding rod 37 are elastically mounted inside the mounting shell 26.

[0033] Since the first arc plate 31 and the first slide rod 38 are connected to the first positioning block 41 via the first connecting rope 40, and the second arc plate 32 and the second slide rod 37 are connected to the second positioning block 42 via the second connecting rope 39, which is a misaligned connection, when the control column 33 slides downward, it will cause the positioning ring, the first positioning block 41 and the second positioning block 42 to pull the first slide rod 38 and the second slide rod 37 upward at the same time. The first slide rod 38 and the second slide rod 37 simultaneously press against the tension spring, causing it to contract and store elastic potential energy. At the same time, it also controls the first arc plate 31 and the second arc plate 32 to rotate upward inside the mounting shell 26, releasing the seal on the adhesive rod 25. At the same time, as the control column 33 slides down, it will also cause the adhesive rod 25 to adhere to the filter screen 3, which is convenient for subsequent cleaning of the filter screen 3.

[0034] The water delivery assembly includes a water delivery cylinder 22, a piston 21, a first water pipe 11, and a second water pipe 23. The water delivery cylinder 22 is fixedly installed on the top of the processing rod 6. The piston 21 is slidably installed inside the water delivery cylinder 22. The first water pipe 11 and the second water pipe 23 are both installed on the water delivery cylinder 22. The other end of the first water pipe 11 extends into the interior of the water ring 4, and the other end of the second water pipe 23 extends into the interior of the water chamber 24. A one-way valve is installed on both the first water pipe 11 and the second water pipe 23. The one-way valve installed on the first water pipe 11 only allows water in the water ring 4 to flow towards the water delivery cylinder 22, and the one-way valve installed on the second water pipe 23 only allows water delivery cylinder 22 to flow towards the water chamber 24.

[0035] Therefore, when the piston 21 slides from left to right inside the water supply cylinder 22, water inside the water ring 4 can be drawn into the water supply cylinder 22 through the first water pipe 11. When the piston 21 slides from right to left inside the water supply cylinder 22, water inside the water supply cylinder 22 can be sent into the water chamber 24 through the second water pipe 23.

[0036] A sealing ring 7 is rotatably installed on the inner wall of the water ring 4.

[0037] One end of the first water pipe 11 extends through the sealing ring 7 into the interior of the water ring 4. Even when the power rod 5 drives the processing rod 6 to rotate, the rotation of the first water pipe 11 will not affect the connection with the water ring 4.

[0038] A driven wheel 13 is rotatably mounted on the top of the processing rod 6. The driven wheel 13 is connected to the rotating gear 8 via a belt. A rotating rod 14 is rotatably mounted inside the driven wheel 13. The rotating rod 14 is engaged with the driven wheel 13 via a plug 15. The plug 15 is inclined. A transmission rod 19 is fixedly mounted on one end of the rotating rod 14. A reciprocating screw 20 is threadedly connected inside the transmission rod 19. The other end of the reciprocating screw 20 is fixedly connected to the piston 21.

[0039] A ratchet 17 is fixedly installed on the outer wall of the transmission rod 19, and a ratchet bar 18 for blocking the ratchet 17 is magnetically installed at the top of the processing rod 6. A coil spring 16 is provided between the ratchet 17 and the driven wheel 13.

[0040] The mounting shell 26 has a slag discharge chamber 27 at one end near the power rod 5. The slag discharge chamber 27 has a slag inlet 28. The slag discharge chamber 27 is connected to the bottom cavity of the power rod 5 through a slag discharge pipe 29. The bottom end of the power rod 5 has a cavity for storing waste, and it can also be discharged from the compartment 1 through an external pipeline.

[0041] When the power rod 5 drives the processing rod 6 to rotate clockwise, the rotating gear 8 rotates under the action of the gear ring 9. Through the belt, it also drives the driven wheel 13 to rotate clockwise. At this time, the driven wheel 13 is in contact with the inclined surface of the insert block 15. At the same time, the transmission rod 19, under the action of the ratchet 18, also blocks the clockwise rotation of the ratchet 17. Therefore, when the driven wheel 13 rotates clockwise, it will not drive the rotating rod 14 and the transmission rod 19 to rotate clockwise. At this time, the driven wheel 13 can only drive the coil spring 16 to rotate. At the same time, the coil spring 16 deforms and stores elastic potential energy. After the adhesive rod 25 cleans the filter screen 3, the drive motor controls the winding wheel 12 to unwind. Through the reset spring, the control column 33 slides upward, and the first arc... Plate 31 and the second arc plate 32 are reset under the action of the tension spring and rotate downward inside the mounting shell 26 to close the adhesive rod 25. At this time, the ratchet 18 is attracted by the electromagnet, which releases the obstruction of the ratchet 17. The coil spring 16 releases its elastic potential energy and drives the transmission rod 19 to rotate counterclockwise. At the same time, the reciprocating screw 20 drives the piston 21 to slide back and forth inside the water delivery cylinder 22. In conjunction with the first water pipe 11 and the second water pipe 23, the water inside the water ring 4 is sent into the water chamber 24 to facilitate the rinsing of the adhesive rod 25. Excess water and impurities will enter the slag inlet 28 through the opening on one side of the first arc plate 31 and the second arc plate 32, and finally be sent from the slag discharge pipe 29 into the cavity at the bottom of the power rod 5 for storage.
