DETAILED DESCRIPTION

[0048] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0049] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0050] The oxygen generation device is based on the principle that the air regeneration agent with superoxide as the main component reacts with water to generate oxygen. At present, the oxygen generation device using potassium superoxide and water usually stores the agent at the top and the water to be reacted at the bottom, and releases the agent at one time when oxygen generation is needed. This design of releasing the agent at one time not only cannot control the oxygen generation rate, but also easily causes the agent to agglomerate. After the agglomeration, the surface of the agent is oxidized but the inside has not reacted, that is, there is a problem of insufficient reaction, which affects the oxygen generation and greatly increases the cost of oxygen generation.

When adding the reagent to be reacted into the water to be reacted, the driving mechanism 5 controls the rotation of the valve core 4 to allow the reagent to be reacted received in the receiving trough to be added into the water to be reacted. The oxygen generating rate of the oxygen generating device can be controlled by controlling the rotation rate of the valve core 4. That is, by this method of adding the reagent in batches and in small batches, the rate at which the oxygen generating device generates oxygen can be controlled, and sufficient reaction between the reagent to be reacted and the water to be reacted can be ensured.

[0054] The oxygen generating device may be placed in a preset space, and the preset space here may be but is not limited to an underground protective building, a laboratory with airtight requirements, etc.

Similarly, a removable cover with good sealing performance should also be provided at the dosing port to ensure the sealing performance of the tank body and the dryness of the interior; the shape and size of the medicine storage tank 2 can be the same as those of the water storage tank 1, that is, it can also be set to a cylindrical tank structure; the bottom of the medicine storage tank 2 is connected to the water storage tank 1 through a dosing pipe 3, and the connection between the dosing pipe 3 and the medicine storage tank 2 and the water storage tank 1 must maintain sealing, and the dosing pipe 3 is a circular tubular pipe structure.

[0057] In order to realize the controllable oxygen production rate of the oxygen production device, the technical solution adopted by the utility model is as follows: Figure 3 , Attachment Fig.10 And attached Fig.11 A valve core 4 is arranged in the medication pipe 3.

At least one medicine receiving groove 41 is arranged around the rotation axis a on the outer peripheral surface of the valve core 4. When the medicine receiving groove 41 faces the medicine storage tank 2, it can receive the reaction agent that matches its volume. When the driving motor 51 drives the valve body to rotate until the medicine receiving groove 41 faces the water storage tank 1, the reaction agent in the medicine receiving groove 41 falls into the water storage tank 1 under the action of gravity, and the reaction agent can react with water to produce oxygen, and the produced oxygen can be discharged to the preset space through the air outlet pipe 6.

[0058] Among them, when the valve core 4 is provided with a medicine receiving groove 41, the driving motor 51 drives the valve core 4 to rotate by 360 degrees each time; when the valve core 4 is provided with two or more medicine receiving grooves 41, the medicine receiving grooves 41 on the valve core 4 should be evenly distributed on the outer peripheral surface of the valve core 4 with the rotation axis a as the center. Taking the valve core 4 as an example in which two medicine receiving grooves 41 are provided, the driving motor 51 drives the valve core 4 to rotate by 180 degrees each time; the number of times the driving mechanism 5 drives the valve core 4 to rotate per minute can be set according to the number and volume of the receiving grooves and the amount of oxygen required to be generated.

The diameter of the main body part 21 is equal everywhere, and the material guide part 22 is located in the accommodating space and its diameter gradually decreases from the top end which is the same as the diameter of the main body part 21 to the bottom end, and its bottom end is connected to the drug administration pipeline. Such a design can make the material guide part 22 conical, which is beneficial to increase the rate at which the reacted agent falls into the drug administration pipeline 3.
