DETAILED DESCRIPTION

[0024] In the following description of the utility model, the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the utility model and simplifying the description, and do not mean that the device must have a specific direction.

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0027] like Figures 1 to 5 As shown, the utility model aims to provide an integrated pulse oxygen controller, comprising a shell 4 consisting of a bottom shell and an upper cover, the shell 4 being provided with an air inlet nozzle 2 and an air outlet nozzle 3, the air inlet nozzle 2 being connected to an oxygen supply device, the upper cover being provided with a display screen 1 and an operation button 7, an integrated circuit board 8 and an integrated airway 10 being provided in the bottom shell, the integrated airway 10 comprising an air inlet airway 10-1 and an air outlet airway 10-2, the air inlet nozzle 2 being connected to an air inlet of a pressure reducing valve 12, the air outlet of the pressure reducing valve 12 being connected to the integrated airway 10 via an electromagnetic valve 11, the upper cover being provided with a display screen and an operation button 1, a circuit board 8 being provided between the display screen 1 and the integrated airway 10, the circuit board 8 being provided with a pressure sensor and a negative micro-pressure sensor 13, the pressure sensor 14 being provided between the air inlet and the electromagnetic valve 11, and the negative micro-pressure sensor 13 being provided between the air outlet and the electromagnetic valve 11.

[0028] The housing 4 of the integrated air duct 10 is provided with a groove for separating the air inlet duct 10 - 1 and the air outlet duct 10 - 2 .

[0029] The pressure sensor is arranged in the "L-shaped" groove between the air inlet nozzle 2 and the pressure reducing valve 12, and the pressure sensor is arranged near the air inlet of the pressure reducing valve 12. The negative micro-pressure sensor 13 is arranged in the "V-shaped" long groove between the solenoid valve 11 and the air outlet nozzle 3.

[0030] After starting the controller, when the user inhales, the negative micro-pressure sensor 13 sends a signal to the circuit board 8 when it detects that the outlet airway 10-2 is under negative pressure. The circuit board 8 controls the solenoid valve to open, and one oxygen path enters the inlet airway 10-1 from the inlet nozzle 2. The pressure sensor detects the pressure of the inlet nozzle, and the other oxygen path passes through the pressure reducing valve and enters the solenoid valve through the inlet airway 10-1. After the solenoid valve is opened, the decompressed oxygen enters the outlet through the outlet airway, and the negative micro-pressure sensor detects the air pressure in the outlet airway. If the air pressure is positive, the solenoid valve is closed, and if the air pressure is negative, the solenoid valve is opened. The integrated circuit board 8 is also provided with an audible and visual alarm system. If the negative micro-pressure sensor does not detect the inhalation action for 15 seconds in a row, an audible and visual alarm will be issued to prevent the user from being in danger of life due to the nasal tube falling off; when the output oxygen pressure is too low or the battery power is too low, an audible and visual alarm will also be issued to ensure the normal use of the product and the safety of the user's life.

[0031] The air inlet nozzle 2 and the air outlet nozzle 3 are arranged on the same side of the housing, and the battery 9 in the housing 4 is arranged at the other end away from the air inlet nozzle 2 and the air outlet nozzle 3. The battery 9 is connected to the Type-C interface 6, and the battery is charged through the Type-C interface. A full charge can be used for 24 hours. The switch 5 of the controller is arranged on the same side as the Type-C interface.

[0032] The integrated circuit board 8 is also provided with a high altitude sensing device, which can automatically adjust the oxygen supply according to the change of altitude without human intervention.

[0033] The display screen of the utility model is a human-computer interaction panel, which can display information such as altitude, oxygen supply and battery power. Users can also select key parameters such as sensing sensitivity and oxygen supply through the display screen panel to meet the personalized needs of different people in different environments.
