[0027] Referring to Figures 1-4 as shown, the present utility model provides a technical solution: a rotary dropper, including a bottle body 1, the surface of the bottle body 1 is threadedly connected with a threaded cap 2, the upper end of the threaded cap 2 is fixedly connected with a rubber head 3, the inner side of the threaded cap 2 is fixedly connected with a drip head 5, and a cap 4 is sleeved on the outer side of the threaded cap 2.
[0028] Next, the overall specific settings and functions will be specifically described.
[0029] In this implementation: a fixed ring 9 is fixedly connected to the inner side of the threaded cap 2, a folding tube 7 is fixedly connected to the lower end of the fixed ring 9, and a bottom plate 10 is fixedly connected to the bottom port of the folding tube 7. During the contraction process of the folding tube 7, the pushing work of the solution can be realized, thus facilitating the suction work of the solution inside the folding tube 7 by the drip head 5.
[0030] A reserved groove 6 is opened on the side wall of the bottle body 1, a guide block 11 is slidably connected to the inner side of the reserved groove 6, and the side walls of the guide block 11 and the bottom plate 10 are fixedly connected. The movement of the bottom plate 10 can be controlled by sliding the guide block 11 inside the reserved groove 6. A connecting pin 13 is fixedly connected to the surface of the guide block 11, and a card strip 14 is rotatably connected to the side wall of the connecting pin 13. The card strip 14 can rotate on the side wall of the connecting pin 13. A number of card slots 12 are evenly opened on the inner side of the reserved groove 6. By rotating the card strip 14 on the connecting pin 13 and clamping the card strip 14 inside the corresponding card slot 12 on the inner side of the reserved groove 6, the fixing work of the lifted guide block 11 can be realized.
[0031] Specifically, a rubber block 15 is adhesively connected to the surface of the card strip 14. By providing the rubber block 15, the tightness of the card strip 14 clamped inside the card slot 12 is increased, thereby improving the stability of supporting the lifted bottom plate 10.
[0032] The rubber block 15 is in the shape of a frustum of a cone. The rubber block 15 with a frustum-of-a-cone structure facilitates the insertion of the clamping strip 14 inside the clamping groove 12. The lower surface of the bottom plate 10 is fixedly connected with a suction cup 8. By providing the suction cup 8, it is convenient to stably place the suction cup 8 on the workbench when the bottle body 1 is not in use.
[0033] Working principle: When it is necessary to suck the solution inside the bottle body, the guide block 11 inside the reserved groove 6 can be slid to control the movement of the bottom plate 10, and then the contraction of the folding tube 7 can be controlled. During the contraction process of the folding tube 7, the solution can be pushed out, thus facilitating the sucking of the solution inside the folding tube 7 by the dropper head 5. After the guide block 11 moves to a suitable position, the clamping strip 14 on the connecting pin 13 is rotated and the clamping strip 14 is clamped inside the corresponding clamping groove 12 in the reserved groove 6, so as to fix the position of the lifted guide block 11, which further facilitates the subsequent sucking of the solution inside the folding tube 7. By providing the rubber block 15, the tightness of the clamping strip 14 clamped inside the clamping groove 12 is increased, thereby improving the stability of supporting the lifted bottom plate 10. The rubber block 15 with a frustum-of-a-cone structure facilitates the insertion of the clamping strip 14 inside the clamping groove 12, further improving the efficiency of inserting the clamping strip 14 into the clamping groove 12. By providing the suction cup 8, it is convenient to stably place the suction cup 8 on the workbench when the bottle body 1 is not in use. By providing the above structure, it is convenient to flexibly push the solution inside the bottle body 1. The staff can suck the solution inside the bottle body 1 without tilting the bottle body 1, avoiding the phenomenon of solution leakage, thereby improving the sucking efficiency of the solution and the use performance of the dropper.
