Furthermore, the input end of the water-gas separator is connected with an oxygen supply device.
Furthermore, the output end of the electromagnetic valve is connected with the oxygen inhalation mask through an air pipe.
Further, the type of the water-gas separator is as follows: UFS-2-3.
Further, the model of the electromagnetic valve is: LD 51.
Further, the pressure sensor has the following types: PX 409.
Further, the model of the MCU is: a low voltage MOSFET.
In summary, due to the adoption of the technical scheme, the invention has the beneficial effects that:
1. the invention can change the oxygen supply frequency according to the respiratory frequency of people, can realize that half of the oxygen supply amount of the original equipment meets the existing requirements, collects the pressure data of expiration and inspiration through the pressure sensor, transmits the signal to the singlechip, controls the opening and closing of the electromagnetic valve by the singlechip, opens the electromagnetic valve when the people inhale, directly outputs the oxygen to the human body, closes the electromagnetic valve when the people exhale, directly improves the oxygen flow when opening, ensures that the oxygen supply can be realized by the oxygen generation equipment only needing half of the ordinary oxygen supply amount, and greatly saves energy and cost.

Drawings
FIG. 1 is a schematic structural view of the present invention;
the labels in the figure are: 101 trachea
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments.
Example 1
Referring to fig. 1, the self-adaptive oxygen inhalation device provided by the invention comprises a water-gas separator, an electromagnetic valve, a pressure sensor and an MCU, wherein an output end of the water-gas separator is connected with an input end of the electromagnetic valve through a gas pipe, an output end of the electromagnetic valve is connected with the pressure sensor, and signal output ends of the electromagnetic valve and the pressure sensor are both connected with a signal input end of the MCU.
After the devices are connected by the connection mode, the device enters a state of ready operation. Because the human body has slight pressure difference when breathing, pipeline internal pressure reduces when breathing in, and pressure is higher in the pipeline when exhaling, and pressure sensor can catch the pressure difference in the pipeline to output high-low level signal to MCU, the signal of pressure sensor that MCU acquireed knows the human body and exhales, the state of breathing in, thereby the break-make of control solenoid valve.
The input end of the electromagnetic valve is connected with the water-gas separator, and the purpose is to remove water gas in the pipeline, because the water gas in the pipeline is too heavy, water drops can be condensed in the pipeline, the pressure detection value in the pipeline can be influenced, and the detection precision of the pressure sensor can be influenced.
Preferably, the water-gas separator is of the type: UFS-2-3.
Preferably, the electromagnetic valve is of the type: LD 51.
Preferably, the pressure sensor is of the type: PX 409.
Preferably, the model of the MCU is: a low voltage MOSFET.
Example 2
Referring to fig. 1, on the basis of the first embodiment, the input end of the moisture separator of the present invention is connected to an oxygen supply device, and the output end of the electromagnetic valve is connected to the oxygen inhalation mask through an air pipe.
When a human body inhales, the pressure sensor detects that the pressure in the pipeline is low, the pressure low level signal is output to the MCU, the MCU obtains the pressure low signal at the moment, an instruction for opening the electromagnetic valve is sent, at the moment, the gas circuit is completely communicated, oxygen can be directly transmitted to the oxygen mask from the oxygen production equipment, at the moment, people can directly inhale the oxygen, when the human body exhales, the pressure sensor detects that the pressure in the pipeline is increased, the pressure high level signal is output to the MCU, at the moment, the MCU obtains the pressure high level signal, the instruction for closing the electromagnetic valve is sent, at the moment, the gas circuit is closed.
When the human body leaves the equipment, at this moment, pressure sensor can not detect the pressure change, at this moment, MCU sends the instruction of closing the solenoid valve, practice thrift oxygen, when the oxygen mask is dressed to the human body, there is pressure change in the pipeline at this moment, pressure sensor feeds back electric signal to MCU, at this moment, the device carries out normal work according to human respiratory frequency, when this device uses at people, can realize practicing thrift half oxygen, when people do not use temporarily, can close the gas circuit immediately, practice thrift a large amount of oxygen, the waste has been avoided.
For example: the common 3L oxygen generator with the device can realize the effect of a 6L oxygen generator and expand the application range of the mini-type machine.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be covered by the appended claims.
