Referring to fig. 2, before the oxygenerator of the present invention works, the rubber plug 19 is pulled out, water is filled into the upper cavity 101 through the water filling port 15, water in the upper cavity 101 flows into the lower cavity 102 through the water filling port 12 and the sleeve 18, the floating disc valve 2 in the lower cavity 102 is lifted up under the buoyancy of water, when the water level in the lower cavity 101 rises to a certain height, the water filling port 12 is blocked by the plug 23 on the floating disc valve 2 under the buoyancy, at this time, water in the upper cavity 101 can not flow into the lower cavity 102 any more, the lower cavity 102 already contains a required water amount, at this time, the water level in the lower cavity 102 also overflows the bottom of the coaming 16, when the oxygenerator works, oxygen produced by the oxygenerator firstly enters the cavity 110 through the air inlet pipe 13, then enters the space between the outer wall of the coaming 16 and the inner wall of the lower cavity 102, then enters the water in the lower cavity 102, oxygen passes through a gap 17 between the bottom of the coaming 16 and the bottom in the lower cavity 102 in the form of bubbles in water, and emerges from the water surface in the coaming 16, oxygen emerging from the water surface in the coaming 16 is humidified, the humidified oxygen enters the concave cavity 110 through the notch 161 and is output to an oxygen outlet of the oxygen generator through the air outlet pipe 14, so that the water content of the oxygen discharged from the oxygen outlet of the oxygen generator is increased to realize humidification of the oxygen, the humidified oxygen can moisten the airway of a patient, the dry oxygen is prevented from stimulating airway mucous membrane, and the alveolus can moisten, the alveolus activity is increased, the exchange of gas is facilitated, in the use process of the oxygen generator, as the water level in the lower cavity 102 is lowered, the float valve 2 is lowered, the plug 23 on the float valve 2 is separated from the end part of the water injection hole 12, namely the water injection hole 12 is opened, the water in the upper cavity 101 flows into the lower cavity 102 again through the water injection hole 12, the water level in the lower cavity 102 rises again, when the water level in the lower cavity 102 rises to a certain height, the rising water level in the lower cavity 102 can make the blockage 23 on the floating disc valve 2 block the water injection hole 12 again, at the moment, water in the upper cavity 101 can not flow into the lower cavity 102 again, the required water quantity is contained again in the lower cavity 102, thus realizing the automatic injection of the water in the lower cavity 102, ensuring the required water quantity always contained in the lower cavity 102, ensuring the humidifying effect of oxygen, not only effectively preventing the water from being contained to exceed the maximum water containing quantity of the humidifying cup due to carelessness of a user, but also avoiding frequent observation of whether the water in the humidifying cup is lower than the minimum water containing quantity, and ensuring the required water quantity always contained in the lower cavity 102 as long as the water in the upper cavity 101 is ensured.
The foregoing description is only of some embodiments of the present invention, and is intended to illustrate the technical means of the present invention, not to limit the technical scope of the present invention. The present invention is obviously modified by those skilled in the art in combination with the prior common general knowledge, and falls within the protection scope of the present invention.
