wherein, the flow resisting mechanism comprises a longitudinal suspender, an expansion spring, a round seat piece, a round separation blade, a lifting rope and a falling ball, the round seat piece is horizontally fastened at the middle part of the inner side wall of the bottom orifice of the three-way connecting pipe, a round air hole is arranged at the middle part of the round seat piece, a longitudinal suspender is arranged at the middle part of a transverse passage inside the three-way connecting pipe, the longitudinal suspender is arranged right above the round seat piece, the bottom rod end of the longitudinal suspender is fastened with the top part of the expansion spring, the bottom part of the expansion spring penetrates through the round air hole downwards and then is fastened on the middle part of the top surface of the round separation blade, the round separation blade is suspended below the round seat piece through the expansion spring, the diameter of the round separation blade is larger than the aperture of the round air hole, one end of the lifting rope is fastened at the center part of the bottom surface of the round separation blade, the other end of the lifting rope is fastened with the falling ball, the falling ball is suspended below the round separation blade through the lifting rope, the dropping ball can be placed in the chimney pipe.

When the liquid storage bottle body is in a normal vertical state, the falling ball in the chimney tube pulls the circular separation blade downwards through the lifting rope due to the self gravity, the circular separation blade and the circular seat blade are pulled apart for a certain distance, the telescopic spring is in a stretched state, and atomized liquid medicine can smoothly enter the three-way connecting pipe from the circular air hole of the circular seat blade; when the liquid storage bottle body is accidentally toppled over, the dropping ball is contacted with the inner side wall of the chimney pipe, and the lifting rope loses the gravity of the dropping ball to pull, so that the circular blocking piece is tightly attached to the bottom surface of the circular seat piece under the action of the resetting and pulling back of the telescopic spring, and the circular air hole is blocked, and the liquid medicine in the liquid storage bottle body is effectively prevented from flowing into the mouth of a patient through the circular air hole.

The invention has the advantages of novel structure, stronger practicability and more humanized design.

The invention is further described below with reference to the accompanying drawings and examples.
