and the inlet of the carbon dioxide absorber 40 is respectively connected with the potassium hydroxide solution outlet of the mixed reaction oxygen generator 30 and the air inlet channel 51, and is used for mixing the potassium hydroxide solution flowing in from the potassium hydroxide solution outlet with the carbon dioxide in the air so as to remove the carbon dioxide in the air.
In the technical scheme provided by the embodiment of the present invention, under the condition that the oxygen content in the air is low, the potassium superoxide reagent feeder 10 may be controlled to feed the potassium superoxide reagent to the feed inlet of the mixed reaction oxygen generator 30, and the water feeder 20 may be controlled to feed water to the feed inlet of the mixed reaction oxygen generator 30, so that the potassium superoxide reagent and water are mixed and reacted in the mixed reaction oxygen generator 30 to form a potassium hydroxide solution, and the potassium hydroxide solution reacts to generate oxygen, so as to supplement the oxygen content to the air in the environment. Compared with the prior art, the potassium superoxide can completely react with water, the oxygen production amount can be added with potassium superoxide medicament and water with required quality according to needs, the reaction controllability is strong, the reaction is complete, and the use safety and controllability of the potassium superoxide can be improved.
The potassium superoxide medicament feeder 10 and the water feeder 20 are controlled by a controller, and the potassium superoxide medicament feeder 10 can be controlled to feed the potassium superoxide medicament to the feeding port of the mixed reaction oxygen generator 30 by sending an oxygen generation request instruction to the controller, and the water feeder 20 is controlled to feed water to the feeding port of the mixed reaction oxygen generator 30. The dosage of the potassium superoxide medicament feeding device 10 is controllable, and the water delivery quantity of the water delivery device 20 is controllable.
In order to overcome the above problems, in an embodiment in which the mixed solution in the mixed reaction oxygen generator 30 is sputtered into the potassium superoxide dosing apparatus 10 due to the fact that the potassium superoxide reagent reacts with water vigorously, the potassium superoxide dosing apparatus 10 includes: the potassium superoxide medicament tank 11 and the feeding valve 12, wherein an inlet of the feeding valve 12 is connected with a discharge hole of the potassium superoxide medicament tank 11, an outlet of the feeding valve 12 is connected with a feeding hole of the mixed reaction oxygen generator 30, a rotary valve core is arranged in the feeding valve 12, the rotary valve core is provided with a first space 121 and a second space 122 which are independently isolated, when the rotary valve core rotates, the first space 121 circulates through the inlet and the outlet of the feeding valve 12, and the second space 122 circulates through the inlet and the outlet of the feeding valve 12.

The oxygen generation request instruction sent to the control device can be operated manually or automatically controlled by a monitoring system, the monitoring system monitors the ambient oxygen concentration, and if the oxygen concentration is lower than a first preset concentration, the oxygen generation request instruction is sent to the control device. In implementation, according to the difference of the ambient oxygen concentration and the size of the ambient space, the required oxygen generation amount is different, and the required oxygen generation amount can be calculated according to a preset calculation scheme, for example, the oxygen generation amount is directly proportional to the size of the ambient space and inversely proportional to the ambient oxygen concentration, the oxygen generation request instruction includes the oxygen generation amount, the potassium superoxide reagent feeder 10 is controlled to deliver the potassium superoxide reagent to the feed port of the mixed reaction oxygen generator 30, and the water feeder 20 is controlled to feed water to the feed port of the mixed reaction oxygen generator 30, including:
