The specific working process is as follows:

when the simple respirator is used for working, firstly, the mask 1 is required to be covered on the face of a patient, then the pressure rod 2 is manually grasped, the pressure rod 2 rotates, the pressure rod 2 can drive the connecting rod 34 to move up and down, the connecting rod 34 further drives the sliding block 7 to move up and down, the air pressure change inside the control tank 6 is realized by the up and down movement of the sliding block 7, the oxygen inside the oxygen bag 3 is continuously led out, the oxygen supply to the outside of the patient is realized, and the hand extrusion force is greatly reduced due to the lever principle of the connecting rod 34; the adjusting knob 15 is rotated manually, so that the adjusting knob 15 rotates up and down in the threaded groove, the second telescopic rod 16 can be compressed through the adjusting knob 15, gas in the second telescopic rod 16 enters the first telescopic rod 14, ejection of the first telescopic rod 14 is realized, the first telescopic rod 14 can drive the adjusting ring 13 to move up and down, adjustment of the inner space of the control tank 6 is realized, when the slider 7 moves up and down for the same distance, different volume changes can be performed in the control tank 6, derivation of oxygen with different volumes is realized, meanwhile, when the slider 7 moves up and down, the adjusting ring 13 can be extruded, the adjusting ring 13 can extrude the annular block 11, the annular block 11 moves up and down, and motion interference between the annular block 11 and the slider 7 is avoided; when the sliding block 7 moves up and down and the adjusting ring 13 is extruded, the adjusting ring 13 can move up and down with the annular block 11, the annular block 11 further moves up and down in the first annular groove, gas in the first annular groove enters the containing box, the air pressure in the containing box is increased, the oxygen bag 3 can be automatically extruded after the air pressure in the containing box is increased, the oxygen in the oxygen bag 3 is promoted to be led out, and particularly when the oxygen in the oxygen bag 3 is insufficient, the oxygen in the oxygen bag 3 can be fully utilized; by rotating the adjusting knob 15, the adjusting knob 15 can drive the switching plate 17 to move up and down in a meshing mode, the direction of oxygen guiding can be controlled through the switching plate 17, when the internal air pressure of the containing box is high, the oxygen can be controlled to be opened through the air inlet hole 20 below the containing box, the oxygen is guided into the guide box 19, and oxygen supply is automatically guided out through the guide box 19, the method can be suitable for patients who can breathe independently but need to be matched with the patients to inhale oxygen, and the oxygen bag 3 is automatically compressed through the air pressure inside the containing box in the process, so that the oxygen in the oxygen bag 3 is guided out, and the working strength of medical workers is reduced; when automatic to patient's oxygen suppliment, long-time oxygen is derived, it is more to lead to patient's inhaled oxygen easily, produce the damage to human organ, press button 21 through medical personnel's manual while, make press button 21 can extrude and correspond third telescopic link 23, the inside gas of third telescopic link 23 can enter into the inside that corresponds the atmospheric pressure groove, realize corresponding piston 25's removal, piston 25 and then can drive and correspond the baffle and move, realize the control to the oxygen passageway through the baffle, when two press buttons 21 arbitrary one or receive the extrusion simultaneously, the oxygen passageway is closed, when press button 21 all do not receive the extrusion, the oxygen passageway is opened, realize the control to the oxygen supply volume, when supplying oxygen through manual extrusion control, only when two press buttons 21 receive the extrusion simultaneously, just can normally supply oxygen, do not touch the problem under the emergency has been avoided; when oxygen is compressed and led out, the rapid leading-out of the oxygen in a short time can be avoided through the moving block 27 and the buffer block 28, and the gas impact on the lung of a patient is reduced; by arranging the pressure valve 30 in the pressure relief groove, when the pressure in the containing box is continuously increased and the pressure in the containing box is higher, the pressure can be effectively relieved through the pressure valve 30 to lead out redundant air pressure, and meanwhile, the vibration film 31 can be blown when the pressure is led out, so that the vibration film 31 can make a sound to remind medical staff of mode switching, timely liberate the medical staff and perform other rescue work; by adding water and the corresponding drugs to the interior of the chamber 38, such as: medicines such as a mucus dissolving agent, a bronchodilator or an inhaled glucocorticoid and the like are required to be taken according to the specific condition of a patient at that time, the heating plate 35 can be controlled to supply power and heat while oxygen is supplied, the heating plate 35 can heat water and medicines to promote evaporation of the water and the medicines, water vapor and medicine vapor can be guided into the oxygen bag 3 through the breathable fabric 39 to be guided out along with the oxygen and inhaled by the patient, on one hand, the water content in the oxygen can be increased, long-time oxygen inhalation is avoided, and the throat is dry and uncomfortable, on the other hand, the medicines can be matched, the patients can be timely subjected to anti-inflammation, bronchospasm relieving, mucoid obstruction symptom relieving, bronchodilation and the like, emergency treatment is assisted, meanwhile, heating of the oxygen is also realized, and the comfort of oxygen inhalation in winter is improved; after the internal pressure who holds the case descends gradually, under the resilience effort of fifth spring 33, observe the inside that piece 32 held the case from new income, remind medical personnel to carry out the manual operation oxygen suppliment.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
