[0019] 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.

[0020] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, an air circulation regulating device for a hyperbaric oxygen chamber includes a hyperbaric oxygen chamber body 1. A ventilation pipe 4 is fixedly installed on the side wall of the hyperbaric oxygen chamber body 1, and the ventilation pipe 4 is in communication with the interior of the hyperbaric oxygen chamber body 1. An air valve 5 is fixedly installed at the outlet end of the ventilation pipe 4, and a mounting base 7 is fixedly installed at the upper end of the air valve 5. A reducer is fixedly installed at the upper end of the mounting base 7, and a servo motor 8 is fixedly installed at the input end of the reducer. An oxygen concentration detector 2 and a motor controller 3 are also fixedly installed on the outer wall of the hyperbaric oxygen chamber body 1. The detection probe of the oxygen concentration detector 2 extends into the interior of the hyperbaric oxygen chamber body 1. The oxygen concentration detector 2 and the motor controller 3 are connected by signal, and the motor controller 3 is electrically connected to the servo motor 8.

[0021] Among them, the oxygen concentration detector 2 is model KZS-100-O2, and the motor controller 3 is model LTS-200A.

[0022] The reducer consists of a sealing shell 6, a driven gear 9, an output shaft 10, a driving gear 11, and an input shaft 12. The sealing shell 6 is fixedly installed on the upper end of the mounting base 7. The output shaft 10 and the input shaft 12 are arranged inside the sealing shell 6. Both ends of the output shaft 10 and the input shaft 12 are rotatably connected to the upper and lower inner walls of the sealing shell 6. The driven gear 9 and the driving gear 11 are fixedly sleeved on the outer walls of the output shaft 10 and the input shaft 12. The driven gear 9 and the driving gear 11 mesh with each other. The servo motor 8 is fixedly connected to the outer wall of the sealing shell 6. The output end of the servo motor 8 is fixedly connected to the end of the input shaft 12.

[0023] The diameter of the driving gear 11 is smaller than the diameter of the driven gear 9.

[0024] With this configuration, the driving gear 11 and the driven gear 9 can form a speed-reducing and force-saving gear set, thereby reducing the stress on the output end of the servo motor 8.

[0025] The air valve 5 has a valve plate 13 inside, and a rotating shaft 14 is arranged in the radial position of the valve plate 13. The rotating shaft 14 is fixedly connected to the valve plate 13. The upper and lower ends of the rotating shaft 14 are rotatably connected to the upper and lower inner walls of the air valve 5, respectively. The upper end of the rotating shaft 14 passes through the mounting base 7 and is fixedly connected to the bottom of the output shaft 10. The rotating shaft 14 is rotatably connected to the mounting base 7.

[0026] The output shaft 10 of the reducer can drive the rotating shaft 14 to rotate, which in turn drives the valve plate 13 to rotate. The rotation of the valve plate 13 can control the opening and closing of the air valve 5, and thus control the opening and closing of the air pipe 4.

[0027] This utility model provides an air circulation regulating device for a hyperbaric oxygen chamber, the specific working principle of which is as follows:

[0028] In use, the oxygen concentration detector 2 can monitor the oxygen concentration inside the hyperbaric oxygen chamber 1 in real time. When the oxygen concentration inside the hyperbaric oxygen chamber 1 approaches 25%, it will transmit a signal to the motor controller 3. The motor controller 3 will then control the servo motor 8 to start for a period of time. The output of the servo motor 8 will drive the input shaft 12 to rotate. The rotation of the input shaft 12 will drive the drive gear 11 to rotate. The rotation of the drive gear 11 will drive the driven gear 9 to rotate, thereby driving the output shaft 10 to rotate. The output shaft 10 can drive the rotating shaft 14 to rotate, thereby driving the valve plate 13 to rotate. The air valve 5 can be controlled to open. Since the pressure inside the hyperbaric oxygen chamber 1 is much greater than that outside, the air inside the hyperbaric oxygen chamber 1 will be quickly discharged to the outside through the ventilation pipe 4 under the action of air pressure. When the oxygen concentration drops to a suitable level, the oxygen concentration detector 2 will send a signal to the motor controller 3 to control the air valve 5 to close. At this time, the air pressure regulation system inside the hyperbaric oxygen chamber 1 will automatically add compressed air to the hyperbaric oxygen chamber 1 (the air pressure regulation system is a built-in function of any hyperbaric oxygen chamber, which will not be described in detail here) to ensure that the air pressure inside the hyperbaric oxygen chamber 1 meets the requirements.
