[0028] In the utility model, when oxygen is output through the air inlet pipe, the connecting channel and the air outlet pipe, the timing mechanism can perform timing, so that statistics can be made according to the patient's actual oxygen inhalation time, and the humidification and heating mechanism can also humidify and heat the oxygen.

[0029] Specifically, the humidification and heating mechanism 6 includes a humidification chamber 7, which is filled with humidification liquid. The rear section of the connecting channel 4 is composed of an air inlet pipeline 8 and an air outlet pipeline 9. The air outlet of the air inlet pipeline 8 is located at the bottom of the humidification chamber 7. The air inlet of the air outlet pipeline 9 is connected to the upper part of the humidification chamber 7 and the connection part is located above the liquid surface of the humidification liquid. The oxygen output from the air inlet pipeline can reach the bottom of the humidification liquid, and can be humidified during the floating process, and then output through the air outlet pipeline located above the liquid surface of the humidification liquid.

[0030] Specifically, the air intake pipe 8 is a spiral tube, and the humidification and heating mechanism 6 further includes an electric heating pipe 10 disposed in the humidification chamber 7, and the electric heating pipe 10 is vertically disposed at the center of the spiral tube. The electric heating pipe can heat the humidification liquid, so the oxygen can be heated both in the air intake pipe 8 and when entering the humidification liquid. The air intake pipe 8 is a spiral tube, which can increase the travel of the oxygen when it is in the heating state, so that the oxygen can be fully heated.

[0031] Preferably, a variable resistor 12 is connected in series to the power supply circuit 11 of the electric heating tube 10, and the flow meter body 1 is provided with an adjusting knob 13 capable of adjusting the variable resistor 12. The power supply circuit can heat the electric heating tube, and the heating temperature of the electric heating tube can be adjusted by the adjusting knob.

[0032] Specifically, combined with Figure 1 and Figure 3 As shown, the timing mechanism 5 includes a No. 1 connecting pipeline 14, a No. 2 connecting pipeline 15 and a No. 3 connecting pipeline 16 which constitute the front section of the connecting channel 4, the No. 1 connecting pipeline 14 is connected to the air inlet pipe 2, the No. 3 connecting pipeline 16 is connected to the air inlet pipeline 8, the No. 2 connecting pipeline 15 is arranged between the No. 1 connecting pipeline 14 and the No. 3 connecting pipeline 16, and the No. 2 connecting pipeline 15 is provided with a ventilation timing component, the ventilation timing component includes a hemispherical valve 17 arranged in the No. 2 connecting pipeline 15, the spherical end of the hemispherical valve 17 faces the air outlet side of the No. 1 connecting pipeline 14 and can form a seal with the contact switch arranged at the air outlet of the No. 1 connecting pipeline 14, and the No. 2 connecting pipeline 15 is also provided with an elastic member 18 which can drive the hemispherical valve 17 to resist the contact switch; it also includes a timer 19 arranged outside the flow meter body 1, and the timer 19 is electrically connected to the contact switch. When the patient inhales oxygen, the oxygen enters the No. 2 connecting pipe 15 through the No. 1 connecting pipe 14, which can push open the semi-ball valve 17 to separate the semi-ball valve and the contact switch. When the contact switch and the semi-ball valve are separated, the timer electrically connected to the contact switch starts timing, so that the patient's oxygen inhalation time can be counted. When the patient does not inhale oxygen, oxygen does not enter the No. 1 connecting pipe 14 through the air inlet pipe. At this time, the elastic member 18 can drive the semi-ball valve 17 to offset the contact switch, and the timer electrically connected to the contact switch stops timing.

[0033] Specifically, the plane end of the hemispherical valve 17 is fixedly connected with a connecting rod 20, and two limiting rods 21 that are slidably matched with the connecting rod 20 are symmetrically arranged on both sides of the second connecting pipeline 15, and the elastic member 18 includes a spring, which is sleeved on the limiting rod 21.

[0034] Preferably, a knob valve 22 is also provided on the air inlet pipe 2. When the knob valve is opened, oxygen can enter through the air inlet pipe. When the patient does not breathe oxygen, the knob valve is closed, and oxygen is no longer input at this time, so that the hemispherical valve can be offset against the contact switch under the action of the spring.
