Description

Technical Field

[0001] This application relates to the field of micro hyperbaric oxygen chamber technology, and more specifically, to a push-button exhaust valve for solving the manual exhaust problem of civilian micro hyperbaric oxygen chambers. Background Technology

[0002] Traditional civilian hyperbaric oxygen chambers typically require manual exhaust. Common manual exhaust valves are complex and inconvenient to operate, increasing the difficulty of use and potentially leading to untimely or excessive exhaust. This can affect the pressure balance and effectiveness within the chamber. Untimely exhaust can cause excessively high pressure, exceeding safety thresholds and damaging the chamber's structure, potentially even resulting in explosions or other serious safety accidents. Excessive exhaust, on the other hand, can cause excessively low pressure, failing to achieve the desired therapeutic effect and even causing adverse effects on the user, such as barotrauma. Utility Model Content

[0003] To address the aforementioned problems, this application provides a push-button exhaust valve that solves the manual exhaust problem in civilian micro-hyperbaric oxygen chambers.

[0004] The push-button exhaust valve provided in this application, which solves the manual exhaust problem in civilian micro-hyperbaric oxygen chambers, adopts the following technical solution:

[0005] A push-button exhaust valve for solving the manual exhaust problem of civilian micro-hyperbaric oxygen chambers includes an oxygen chamber body and an exhaust valve. The exhaust valve is located on one side of the oxygen chamber body, and the exhaust valve is equipped with a two-way exhaust component inside.

[0006] The bidirectional exhaust assembly includes a valve seat, and a button is provided at the end of the exhaust valve away from the valve seat. Both the exhaust valve end and the button have through holes inside. The button and the valve seat are used to drive the exhaust valve to exhaust in both directions.

[0007] Furthermore, the number of through holes is set to multiple, and the multiple through holes are distributed in an array along the axis of the exhaust valve. The outer wall of the exhaust valve is provided with a threaded sleeve, one side of which is threaded with a nut, and a pin is provided between the other side of the threaded sleeve and the exhaust valve.

[0008] Furthermore, a silicone ring is provided on one side of the screw sleeve, which is located between the outer wall of the exhaust valve and the inner wall of the screw sleeve. Multiple slots are provided inside the main body of the oxygen chamber, and the multiple slots are arranged in an array along the axis of the exhaust valve.

[0009] The above technical solution, through the setting of the bidirectional exhaust component, enables rapid bidirectional exhaust.

[0010] Furthermore, the exhaust valve is equipped with a pressure balancing assembly, which includes a main balancing chamber and a secondary balancing chamber, with two secondary balancing chambers.

[0011] Furthermore, the outer wall of the main balancing cavity is connected to a support frame, and the number of support frames is set to multiple, with the multiple support frames distributed at equal distances along the axis of the main balancing cavity.

[0012] Furthermore, a piston is installed inside the main balancing chamber, and springs are fixedly connected to both sides of the piston. One end of each spring is fixedly connected to the inner wall of the main balancing chamber.

[0013] Furthermore, connection holes are provided on both inner walls of the main balance chamber.

[0014] The above technical solution effectively reduces pressure fluctuations during bidirectional exhaust, making the exhaust process more stable.

[0015] Furthermore, the exhaust valve is equipped with two filters inside, located on opposite sides of the exhaust valve.

[0016] The above technical solutions prevent impurities from causing wear, blockage, or damage to the internal structure of the exhaust valve, thus extending the service life of the exhaust valve.

Detailed Implementation

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] Example 1

[0029] Reference Figures 1-3 A push-button exhaust valve for solving the manual exhaust problem of civilian micro-hyperbaric oxygen chambers includes an oxygen chamber body 1 and an exhaust valve 2. The exhaust valve 2 is located on one side of the oxygen chamber body 1, and the exhaust valve 2 is equipped with a bidirectional exhaust component inside.

[0030] The bidirectional exhaust assembly includes a valve seat 3, and an exhaust valve 2 with a button 7 at the end away from the valve seat 3. Both the exhaust valve 2 and the button 7 have through holes 9 inside. The button 7 and the valve seat 3 are used to drive the exhaust valve 2 to exhaust in both directions.

[0031] Reference Figures 1-3The number of through holes 9 is set to be multiple, and the multiple through holes 9 are arranged in an array along the axis of the exhaust valve 2. The outer wall of the exhaust valve 2 is provided with a screw sleeve 6. A nut 5 is threadedly connected to one side of the screw sleeve 6. A pin 4 is provided between one side of the screw sleeve 6 and the exhaust valve 2. A silicone ring 8 is provided on one side of the screw sleeve 6. The silicone ring 8 is located between the outer wall of the exhaust valve 2 and the inner wall of the screw sleeve 6. The interior of the oxygen chamber body 1 is provided with multiple slots 18, and the multiple slots 18 are arranged in an array along the axis of the exhaust valve 2.

[0032] The bidirectional exhaust assembly enables the exhaust valve 2 to perform bidirectional exhaust. Specifically, the operation involves first installing the exhaust valve 2 onto the oxygen chamber body 1, then manually pulling the valve seat 3 and rotating it 90 degrees clockwise or counterclockwise. During this process, the pin 4 is precisely engaged with the threaded sleeve 6. At this point, the air pressure inside the oxygen chamber body 1 can be smoothly discharged through the central opening of the valve seat 3.

[0033] If a person outside the oxygen chamber body 1 performs the operation, first pull button 7 to rotate it 90 degrees clockwise or counterclockwise, then pull it outward. When pin 4 is precisely locked in the slot 18 of the screw sleeve 6, the pressurized air inside the oxygen chamber body 1 can also be exhausted outward through the hole in the center of valve seat 3.

[0034] The bidirectional exhaust assembly enables rapid bidirectional exhaust, timely adjustment of the pressure inside the oxygen chamber 1, ensuring pressure balance and improving exhaust efficiency. Exhaust valve 2 can be easily operated for exhaust from both inside and outside the oxygen chamber 1 without the need for complicated tools, thus improving ease of use. Furthermore, precise exhaust control helps maintain a stable and safe pressure environment inside the oxygen chamber 1, reducing safety risks caused by abnormal pressure.

[0035] Example 2

[0036] Reference Figures 3-6 The difference between this embodiment and Embodiment 1 is that the exhaust valve 2 is provided with a pressure balancing assembly inside. The pressure balancing assembly includes a main balancing chamber 12 and a secondary balancing chamber 13. The number of secondary balancing chambers 13 is set to two. The outer wall of the main balancing chamber 12 is connected to a support frame 11. The number of support frames 11 is set to multiple. The multiple support frames 11 are distributed at equal distances along the axis of the main balancing chamber 12. The main balancing chamber 12 is provided with a piston 15 inside. Springs 16 are fixedly connected to both sides of the piston 15. One end of the two springs 16 is fixedly connected to both sides of the inner wall of the main balancing chamber 12. Both sides of the inner wall of the main balancing chamber 12 are provided with connection holes 14. Each secondary balancing chamber 13 is connected to the interior of the main balancing chamber 12 through the corresponding connection hole 14. The two secondary balancing chambers 13 are located on the outer walls of both sides of the main balancing chamber 12. The two secondary balancing chambers 13 are staggered. Multiple air inlets 17 are provided on the side of the two secondary balancing chambers 13 that are far apart from each other.

[0037] The pressure balancing assembly can effectively balance and buffer pressure during bidirectional exhaust. Specifically, when gas is exhausted from one direction, it enters the corresponding secondary balance chamber 13 through the corresponding air inlet 17, and then enters the main balance chamber 12 through the corresponding connection hole 14. The gas pressure pushes the piston 15 to move in the main balance chamber 12, compressing the corresponding spring 16. When the piston 15 moves to the designated position, the other connection hole 14 is exposed, and the gas enters the other secondary balance chamber 13 through the connection hole 14, and then exits from the corresponding air inlet 17, thereby achieving pressure balance.

[0038] The pressure balancing component can effectively reduce pressure fluctuations during bidirectional exhaust, making the exhaust process more stable. By buffering pressure changes, it can reduce wear and damage to the internal components of exhaust valve 2, extend the service life of exhaust valve 2, reduce equipment maintenance and replacement costs, and the stable pressure balancing process can reduce noise and vibration caused by gas flow, improving the comfort of the user environment.

[0039] Reference Figure 4 The exhaust valve 2 is equipped with a filter screen 10 inside. There are two filter screens 10, which are located on the two sides inside the exhaust valve 2 respectively.

[0040] The filter screen 10 can effectively block solid particles, dust, debris and other impurities that may be present in the gas, preventing these impurities from entering the exhaust channel, thereby avoiding wear, blockage or damage to the internal structure of the exhaust valve 2 and extending the service life of the exhaust valve 2.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
