Detailed ways

Below in conjunction with accompanying drawing, the utility model content is described in further detail.

As shown in Figures 1 to 3, an intelligent oxygen flow meter includes a humidification bottle 1, an oxygen flow indicator tube 2, an inlet tube 3, an outlet tube 4, an escape tube 11, a flow control valve 6, and a timing opening and closing control device 5. The humidification bottle 1 will not inhale dry pure oxygen to the patient during oxygen inhalation, so the oxygen will pass through the humidification bottle 1, so that the oxygen breathed into the human body has a certain humidity. Oxygen flow indicator tube 2 is actually a transparent scale with a steel ball or plastic round ball inside, which can move upwards under the blowing of oxygen, so that the oxygen flow can be indicated. An oxygen flow indicator tube 2 is installed on the upper end of the humidification bottle 1 . An escape pipe 11 is installed in the humidification bottle 1 . The air inlet pipe 3 and the air outlet pipe 4 are connected to the upper end side of the humidification bottle 1 . The air intake pipe 3 communicates with the air outlet pipe 4 through the escape pipe 11 . The flow control valve 6 is installed at the bottom of the oxygen flow indicator tube 2, and controls the opening and closing of the flow and the flow rate of the inner layer tube of the oxygen flow indicator tube 2 through the flow control valve 6.
