Description

Technical Field

[0001] The present invention relates to the technical field of micro-hyperbaric oxygen chambers, and in particular to a device and method for detecting oxygen concentration and oxygen flow rate of a micro-hyperbaric oxygen chamber. Background Art

[0002] The micro-hyperbaric oxygen chamber uses an oxygen concentrator to introduce high-concentration oxygen into the chamber, providing users with nasal inhalation or diffuse oxygen supply. The home micro-hyperbaric oxygen chamber allows patients to inhale high-concentration oxygen in a micro-high-pressure environment, thereby increasing the oxygen content in the blood, which can significantly improve physical function and effectively relieve physical fatigue.

[0003] Before the micro-hyperbaric oxygen chamber is shipped from the factory, it is necessary to test the oxygen concentration and flow of the oxygen production system at different chamber pressures. The existing method of testing oxygen concentration and flow often connects the oxygen production system to the oxygen chamber, and then inflates and pressurizes the chamber to reach the set pressure value. This testing method is inconvenient, difficult to move, inefficient, and costly. Summary of the invention

[0004] The object of the present invention is to provide a device and method for detecting the oxygen concentration and oxygen flow rate of a micro-hyperbaric oxygen chamber, which does not require the large oxygen chamber to be inflated and pressurized, and can conveniently and efficiently detect the oxygen concentration and flow rate of the oxygen production system under different back pressures, so as to solve the technical problems existing in the above-mentioned background technology.

[0005] To achieve the above object, the technical solution of the present invention is as follows:

[0006] A detection device for oxygen concentration and oxygen flow rate of a micro-hyperbaric oxygen chamber comprises: an air inlet, a digital flowmeter, a three-way valve, a pressure tank, a rotor flowmeter, a solenoid valve and an air outlet. High-concentration oxygen produced by the micro-hyperbaric oxygen chamber enters the air inlet, the air inlet is connected to the air inlet end of the digital flowmeter, the air outlet end of the digital flowmeter is connected to the inlet of the three-way valve, the first outlet of the three-way valve is connected to the rotor flowmeter, an oxygen concentration sensor is arranged in the airway of the rotor flowmeter, and the second outlet of the three-way valve is connected to the pressure tank, the solenoid valve and the air outlet in sequence.

[0007] Furthermore, the rotor flowmeter is a micro rotor flowmeter, and the exhaust end of the rotor flowmeter is connected to the atmosphere.

[0008] Furthermore, the oxygen concentration sensor is a galvanic cell type oxygen sensor.

[0009] Furthermore, a pressure sensor for detecting gas pressure is arranged in the pressure tank, and a pressure switch is also arranged on the pressure tank, and the pressure switch controls the opening and closing of the solenoid valve.

[0010] Furthermore, it also includes: a first digital display board, a second digital display board and a third digital display board, the first digital display board is connected to the signal transmission end of the digital flow meter, the second digital display board is connected to the signal transmission end of the oxygen concentration sensor, and the third digital display board is connected to the signal transmission end of the pressure sensor.

[0011] Furthermore, it also includes: a shell, the air inlet is arranged on the front end side of the shell, the air outlet is arranged on the right end side of the shell, and the first digital display board, the second digital display board and the third digital display board are respectively integrated at the front end of the shell.

[0012] Furthermore, the digital flow meter, three-way valve, pressure tank, rotor flow meter, oxygen concentration sensor, pressure sensor, pressure switch and solenoid valve are all arranged inside the shell.

[0013] Furthermore, a handle is provided on the top of the shell.

[0014] A method for detecting oxygen concentration and oxygen flow rate in a micro-hyperbaric oxygen chamber comprises the following steps:

[0015] The high-concentration oxygen produced by the oxygen production system of the micro-hyperbaric oxygen chamber is passed from the air inlet to the digital flow meter, the digital flow meter detects the flow value and displays it on the first digital display panel, and then the high-concentration oxygen is passed to the inlet of the three-way valve;

[0016] Part of the high-concentration oxygen flows from the first outlet of the three-way valve to the micro rotor flowmeter, then the oxygen concentration value is detected by the oxygen concentration sensor and displayed on the second digital display panel, and finally flows to the atmosphere;

[0017] Another part of high-concentration oxygen flows from the second outlet of the three-way valve to the pressure tank. The pressure in the pressure tank increases to reach the set pressure value of the micro-hyperbaric oxygen chamber. The built-in pressure sensor of the pressure tank detects the pressure value and displays it on the third digital display panel. When the pressure in the pressure tank exceeds the set pressure value, the pressure switch transmits an electrical signal to the solenoid valve to open the valve, and the gas in the pressure tank flows out. When the pressure in the pressure tank is lower than the set pressure value, the pressure switch transmits an electrical signal to the solenoid valve to close the valve.

[0018] Compared with the prior art, the present invention has the following beneficial effects:
