Embodiment 1

[0026] Figure 1 to Figure 3 A first embodiment of the invention is shown, in which figure 1 is a schematic cross-sectional view of the first structure of the present invention; figure 2 yes figure 1 The enlarged schematic diagram of the local structure at A; image 3 yes figure 1 The enlarged schematic diagram of the local structure in B.

[0027] Present embodiment is a kind of portable fully automatic oxygen supply device, see figure 1 and figure 2 , including casing 1, liquid storage chamber 2, catalytic reaction chamber 3, humidification chamber 4, battery compartment (not shown on the figure), and the rigidity that is used to draw the liquid in liquid storage chamber 2 into catalytic reaction chamber 3 The telescopic piston 6 and the electric drive device 5 for driving the rigid telescopic piston 6 communicate with the liquid storage chamber 2 , the catalytic reaction chamber 3 and the humidification chamber 4 in sequence. The battery in the battery compartm...

Embodiment 2

[0037] This embodiment is basically the same as Embodiment 1, the difference is that: the humidification chamber 4 is provided with a flow control valve for controlling the oxygen discharge; when in use, just connect the exhaust port of the flow control valve to the oxygen inhalation pipe Oxygen.

[0038] In this embodiment, a bolt assembly is used to fixedly connect the pressing rod of the pumping assembly to the rigid retractable piston in the electric drive device, so that the liquid can be pumped more conveniently.

Embodiment 3

[0040] This embodiment is basically the same as Embodiment 2, except that the catalytic reaction chamber 3 is also provided with an explosion-proof safety valve. If the oxygen generation rate in the catalytic reaction chamber 3 is too fast, the air pressure will rise sharply. After the preset pressure of the valve is reached, the airflow is discharged from the explosion-proof safety valve to the atmosphere, thereby achieving the effect of explosion-proof protection.

Abstract

The invention discloses a portable type full automatic oxygen supply device. The device comprises a casing, a liquid storage chamber, a catalytic reaction chamber, a humidifying chamber, a rigid telescopic piston which is used for pumping the liquid in the liquid storage chamber into the catalytic reaction chamber, and an electric driving device which is used for driving the rigid telescopic piston. The liquid storage chamber, the catalytic reaction chamber and the humidifying chamber are communicated in turn. The oxygen supply device has the advantages of simpler structure, higher efficiency, and convenient oxygen supply speed and oxygen supply quantity regulation.

Description

technical field [0001] The invention belongs to the technical field of oxygen making equipment, and in particular relates to a portable full-automatic oxygen supplier. Background technique [0002] At present, there are two main sources of medical oxygen: one is physical method and the other is chemical method. The physical method usually uses a high-pressure gas storage cylinder with oxygen for oxygen supply, or uses a molecular sieve oxygen generator to collect oxygen from the air in real time for oxygen supply; the disadvantage of using a high-pressure gas storage cylinder for oxygen supply is that the gas storage used Bottles need to withstand high pressure, so generally high-pressure containers are bulky and inconvenient to carry and use; the disadvantage of using molecular sieve oxygen generators is that they are not only large in size and heavy in weight, but also need to be supplied by commercial power. If it is on a high mountain in the wild, such as the Qinghai-Ti...
