The term "inside" and "outside" refer to the inside and the outside of the contour of each member itself. In addition, "a plurality" referred to in the present invention means two or more and includes two.

FIG. 1 is an internal structure view of a dew-water collecting apparatus of the present invention; fig. 2 is a schematic block diagram of the dew-water collecting apparatus of the present invention. As shown in fig. 1-2, the dew-water collecting device provided by the embodiment of the present invention includes: the liquid collecting device comprises a liquid collecting main body 1, a filtering cover body 8 and a liquid collecting device 15.

The top end of the liquid collecting main body 1 is connected with an installing mechanism. Preferably, the mounting mechanism is embodied as a suspension mechanism, wherein the suspension mechanism comprises a hook 26 and a catch 27, the catch 27 being in a compressed state when the collector body is suspended from a branch or trunk. It will be appreciated by those skilled in the art that other arrangements are also conceivable by those skilled in the art to enable the dew collecting means to be suspended from a branch or trunk.

The fluid collecting body 1 has an upper end portion and a lower end portion, wherein the diameter of the cross section from the upper end portion of the fluid collecting body to the middle portion of the fluid collecting body is gradually increased, and the diameter of the cross section from the middle portion of the fluid collecting body to the lower end portion of the fluid collecting body is gradually decreased, so that the outer wall of the fluid collecting body 1 forms a curved surface.
