[0025] Working principle:

[0026] Adjustment phase

[0027] By manually rotating the threaded rod 402 on the threaded barrel 403, the length between the threaded rod 402 and the threaded barrel 403 can be adjusted. At the same time, the first connecting block 305 and the second connecting block 405 at the ends of the threaded rod 402 and the threaded barrel 403 are restricted so that the first connecting block 305 and the second connecting block 405 can pull and squeeze the medicine box top 302 and the medicine box bottom 1 in a bidirectional manner, and the telescopic rubber ring 301 in the center of the medicine box top 302 and the medicine box bottom 1 can be synchronously expanded and contracted, so that the internal space of the entire medicine box can be adjusted at will, and the volume can be adjusted according to the actual amount of liquid medicine.

[0028] Preparation

[0029] After being assembled and fixed with the drone by screws passing through the connecting frame 6, the protrusion 5 on the outer wall of the top 302 of the medicine box is aligned with the connecting frame 6 and inserted so that the connecting frame 6 and the protrusion 5 can achieve the effect of abutting and fixing. Then, medicine is injected into the interior through the large-aperture medicine injection port 7, so that the buoyancy generated by the medicine causes the float 10 to rise until the sealing ring 11 on the surface of the float 10 is tightly pressed against the top 302 of the medicine box, thereby providing a prompt that the interior is full.

[0030] Use phase

[0031] After the medicine outlet 2 is connected to the drone spraying component, the rubber square rod 303 and the round rod 304 block the swing of the internal medicine, so that when the drone moves, the shaking amplitude of the medicine at the bottom 1 of the medicine box is reduced, avoiding the inertia of the shaking of the medicine, making the drone spraying process more stable.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
