The implementation principle of the embodiment is as follows: when the isolation tent system is used, a patient is in the protection tent body 2, the first fan 41 or the second fan 42 is started to enable the interior of the protection tent body 2 to be in a negative pressure state, at the moment, fresh air enters the protection tent body 2 from the air inlet 22, pumped gas enters the air pumping pipe 3 from the air pumping port 23, then the pumped gas is purified by the air pumping pipe 3 to the purification box 4, the pumped gas is purified by the disinfection and filtration device 44, the sterilization device 45 and the harmful substance decomposition device 47, and the gas is discharged out of the purification box 4 after being purified; when the interior of the protection net body 2 is in a positive pressure state, air enters the purifying box 4 through the first fan 41 or the second fan 42, and enters the protection net body 2 through the exhaust pipe after being purified in the purifying box 4, so that the air entering the protection net body 2 can be ensured to be clean.
When the first fan 41 or the second fan 42 fails, the worker may start another normal fan, and draw out air by using the normal fan; when the power failure occurs, the storage battery 43 can be utilized to keep the first fan 41 or the second fan 42 working normally, so that the whole isolation account system can operate normally, and the working stability of the isolation account system is improved.
The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
