Then, the circular sliding column enters another connecting groove section, the rack moves, and the outer gear ring and the adsorption ring 32 rotate to perform adsorption unit switching again.

In some embodiments of the present invention, as shown in fig. 8, the suction ring 32 can be rotated by a motor and gear transmission system 35, which can be controlled by the forward rotation, reverse rotation, and stop rotation of the motor.

In some embodiments of the present invention, the air purification system 11 includes a dust removal booster fan, a filter absorber, a temperature and humidity regulation module, and a harmful gas adsorption module. The inlet of the dust removal booster fan is a fresh air inlet and is communicated with the outer side of the defense collecting space 10. The filter absorber is communicated with the outlet of the dedusting booster fan. The harmful gas adsorption module comprises a fan, a purification filter element, an electric heater, a vacuum pump and an electromagnetic valve, wherein the purification filter element of the harmful gas adsorption module is a renewable filter element so as to adsorb the harmful gas in a physical adsorption mode, and the harmful gas adsorption module adsorbs the harmful gas at normal temperature and desorbs the harmful gas at high temperature. And the air inlet of the harmful gas adsorption module is communicated with the outlet of the filter absorber.

The temperature and humidity adjusting module comprises a refrigeration compressor, a refrigeration condenser, a refrigeration evaporator, an expansion valve, an evaporation fan and an electric heating assembly. The gas flowing out of the purification gas port of the harmful gas adsorption module is cooled and/or dehumidified through the refrigeration evaporator, the cooled and/or dehumidified gas is controllably heated through the electric heating assembly, and the post gas enters the prevention collecting space 10. In this embodiment, a plurality of bypass lines and corresponding valves may also be provided, such as a bypass line disk bypassing the refrigeration evaporator, so that the gas is not cooled and/or dehumidified; a bypass line bypassing the electrical heating assembly so that the gas is not heated; a bypass line is provided between the gas inlet of the harmful gas adsorption module and the purge gas port so that the gas is not purged.

In order to improve the efficiency, the exhaust gas outlet of the harmful gas adsorption module is communicated with the air inlet of the condenser of the temperature and humidity adjusting module through a pipeline. The air inlet of the condenser of the temperature and humidity control module is further communicated with the pre-storage cavity 13, so that the air in the pre-storage cavity 13 enters the air treatment device 30 or flows to the condenser of the temperature and humidity control module under the action of the first control valve 14, and finally enters the environment outside the defense collecting space 10.

In some embodiments of the present invention, the air compression storage device 20 includes an air compressor and an air tank. The inlet of the air compressor is communicated with the outlet of the air processing device 30, the outlet of the air compressor is communicated with the air storage tank, and the outlet of the air storage tank is communicated with the defense collecting space 10. Preferably, the air compression storage device 20 further includes an oxygen generation module, the oxygen generation module includes a molecular sieve component, an oxygen storage tank and a third control valve, and the oxygen generation module adopts a molecular sieve pressure swing adsorption mode to generate oxygen. The air inlet of system oxygen module communicates air compressor's export, and the third control valve makes the air current of air compressor's export get into system oxygen module or gas holder controllablely, and the export of gas holder and system oxygen module all communicates with the import of second control valve 40. The nitrogen discharging port of the oxygen generation module is communicated with the air inlet of the condenser of the temperature and humidity adjusting module. The air compression storage device 20 in the embodiment of the present invention can store the air from the pre-storage chamber 13 first, and only store the oxygen in the air after the air storage is completed, so as to improve the storage efficiency. When in use, air or oxygen can be conveyed into the defense collecting space 10 according to requirements.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
