The working principle is as follows: when the air purifier is used, the bidirectional heat dissipation fan 604 is electrified to generate wind power, the bidirectional heat dissipation fan 604 generates suction force from the bottom in a normal state, and blows out outside air to the top of the direct-current power supply cabinet 1, and when the bidirectional heat dissipation fan 604 generates suction force to suck the outside air into the middle of the detachable heat dissipation assembly 6, the outside air firstly penetrates through the adaptive adjustment air inlet assembly 7 and then enters the inside of the first connecting frame 602, and the filter frame 606 is wrapped by the water absorption silk screen 609, so that the outside air can penetrate through the water absorption silk screen 609 to be driven by the bidirectional heat dissipation fan 604 to be blown to the top of the direct-current power supply cabinet 1 through the filter frame 606, impurity removal and dehumidification can be carried out on the sucked air through the water absorption silk screen 609, and the condition that impurities and moist air are blown to the inside of the direct-current power supply cabinet 1 to cause damage to equipment inside the direct-current power supply cabinet 1 can be avoided, the dust of the water absorbing screen 609 is more, at this time, the detaching plate 607 can be separated from the detachable enclosure 601, and the detaching plate 607 drives the first drawing plate 608 to be drawn out from the inside of the first connecting frame 602, and at the same time, the detaching plate 607 drives the second drawing plate 613 to be removed from the bottom of the bottom plate 4, at this time, the second drawing plate 613 draws out the water absorbing screen 609 to be cleaned and replaced, at the same time, because the first drawing plate 608 and the water absorbing screen 609 are simultaneously removed, the first dust removing opening 611 is matched with the second dust removing opening 612, so that the inside of the first connecting frame 602 is directly communicated with the outside, the first connecting frame 602 can be cleaned from the bottom of the first connecting frame 602, and when the bidirectional heat dissipating fan 604 needs to be repaired and replaced, the detachable enclosure 601 can be detached from the dc power cabinet 1 to move the first connecting frame 602 out of the top of the mounting frame 3 from the inside of the dc power cabinet 1, at this time, the bidirectional heat dissipation fan 604 can be maintained and replaced, when the adaptive adjustment air intake assembly 7 is used, the detachable enclosure 601 and the first connection frame 602 are installed in place, then the second connection frame 707 penetrates through the detachable enclosure 601 and is inserted into the first connection frame 602, so that the inside of the second connection frame 707 is communicated with the inside of the first connection frame 602, at this time, the fixing frames 701 are installed at both ends of the detachable enclosure 601 through bolts, during normal use of the adaptive adjustment air intake assembly 7, the ventilation slots 703 serve as air flow channels, so that the external air can quickly penetrate through the fixing frames 701 and the second connection frame 707 from the outside and enter the inside of the first connection frame 602, and when the external air is moist, the moist air can move on the inner wall of the first installation plate 603 and be continuously absorbed by the first water-swelling strips 704 and the second water-swelling strips 705, so that the first water-swellable strip 704 and the second water-swellable strip 705 absorb water and swell, and the swelling of the first water-swellable strip 704 is restricted by the guiding post 706, so that the swelling range of the first water-swellable strip 704 is defined, and at this time, a structural structure of a tesla valve is formed inside the fixing frame 701, that is, it is difficult for external air to penetrate through the fixing frame 701 through the ventilation slot 703 at the swelling position of the second water-swellable strip 705 and the first water-swellable strip 704, that is, the amount of external humid air entering the first connection frame 602 is reduced, under the influence of the negative pressure of the first connection frame 602, the external air at the dry position is accelerated to be sucked into the inside of the first connection frame 602 through the ventilation slot 703, and when the wind force generated by the bidirectional heat dissipation fan 604 is detected by the wind force detection sensor 605 to be reduced to a target value, the bidirectional heat dissipation fan 604 blows in the reverse direction, and the bidirectional heat dissipation fan 604 makes the high temperature inside the dc power supply cabinet 1 be sucked from the first connection frame 602, the second water-swellable strip 704, the second connection frame 707 and the fixing frame 701 are discharged outwards, due to the one-way circulation structure of the tesla valve, the ventilation slots 703 at the expansion positions of the second water-swelling strip 705 and the first water-swelling strip 704 do not affect the reverse blowing of the airflow, then the high-temperature airflow inside the dc power supply cabinet 1 can dry the second water-swelling strip 705 and the first water-swelling strip 704 at this time, so that the adaptive adjustment air inlet assembly 7 can be restored to the initial state, and the time of the reverse rotation of the bidirectional heat dissipation fan 604 is controlled to be half an hour, because the inside of the fixing frame 701 enters humid air, this makes the air at the bottom of the dc power supply cabinet 1 humid, the bidirectional heat dissipation fan 604 can dry the second water-swelling strip 705 and the first water-swelling strip 704 during the reverse rotation of the bidirectional heat dissipation fan 604 for half an hour, and can also blow the humid air at the bottom of the dc power supply cabinet 1 at the same time, and then the bidirectional heat dissipation fan 604 is restored to the normal forward blowing, so that the device can be reused.
