The invention provides a waterproof breathable structure, a detection device and an unmanned aerial vehicle. The waterproof and breathable structure comprises a device cavity used for containing a functional device, a waterproof cavity, a communication hole, a shell, a waterproof ventilation film and a water absorption structural part, wherein the waterproof cavity and the device cavity are arranged in a spaced mode, the communication hole is communicated with the device cavity and the waterproof cavity, the shell is communicated with the waterproof cavity and an outer ventilation hole, the waterproof ventilation film covers the ventilation hole and is connected with the shell in a sealed mode, and the water absorption structural part is located in the waterproof cavity and can absorb andlock the water. The waterproof and breathable structure is advantaged in that while ventilation of the waterproof cavity and the device cavity is achieved, the water can be prevented from entering, double isolation of functional devices in the device cavity is realized by arranging the waterproof cavity which is arranged at an interval with the device cavity on the shell, and the water absorptionstructural part is arranged in the waterproof cavity to absorb and latch a small amount of water penetrating through the waterproof breathable film, so the small amount of water is prevented from entering the device cavity, and triple isolation of the functional devices in the device cavity is realized.

    本发明提供了一种防水透气结构、检测装置及无人机,防水透气结构包括有用于放置功能器件的装置腔、与所述装置腔间隔设置的防水腔、连通所述装置腔与所述防水腔的连通孔以及连通防水腔与外部的透气孔的壳体、覆盖所述透气孔且密封连接于所述壳体的防水透气膜及位于所述防水腔中且能够吸收并锁住水分的吸水结构件。本发明在实现对防水腔和装置腔通风的同时也能够防止水体进入,通过在壳体上开设与所述装置腔间隔设置的所述防水腔实现了对装置腔内的功能器件的双重隔离,又通过在防水腔内设置吸水结构件将透过所述防水透气膜的少许水分吸收并锁存,防止此少许水分进入所述装置腔,实现了对装置腔内的功能器件的三重隔离。
