[0031] Reference Figures 1 to 10 A convenient rotary switch dropper includes a rubber head 1 and a tube body 2 fixedly connected together. The rubber head 1 has a certain elasticity. It also includes: a threaded cap 3, in which the rubber head 1 is fixedly installed; and a pusher 4, installed above the rubber head 1. The pusher 4 is movably connected to the threaded cap 3, and its up-and-down movement can squeeze and release the rubber head 1. Figure 4 As shown, a guide rib 41 is provided on the outer side wall of the push-button 4; the outer shell 5, as... Figure 5 As shown, the inner side of the outer shell 5 is provided with a guide slope 51, and the upper end of the guide rib 41 abuts against the guide slope 51. The outer shell 5 is kinetically connected to the press head 4, and the outer shell 5 can rotate relative to the press head 4. The rotation of the outer shell 5 drives the press head 4 to move up and down. By rotating the outer shell 5, the press head 4 can move up and down, and the press head 4 can squeeze and release the rubber head 1 to realize the self-aspiration of liquid by the dropper, without the need to manually press the press head 4, thus improving the convenience of operation.
[0032] In a preferred embodiment, such as Figure 3 As shown, the threaded cap 3 has two longitudinal limiting grooves 31 on its side wall, which are arranged opposite to each other, as shown in the figure. Figure 4As shown, the lower end of the guide rib 41 is provided with a sliding buckle 411 (the number and position of the guide rib 41 correspond to the longitudinal limiting groove 31). The sliding buckle 411 is installed in the longitudinal limiting groove 31. The sliding buckle 411 can slide up and down along the longitudinal limiting groove 31. The vertical sliding of the push head 4 is restricted by setting the longitudinal limiting groove 31 and the sliding buckle 411.
[0033] In a preferred embodiment, such as Figure 3 As shown, the outer wall of the threaded cap 3 is provided with a first anti-rotation rib 32 and a second anti-rotation rib 33. The first anti-rotation rib 32 and the second anti-rotation rib 33 are arranged on both sides of the longitudinal limiting groove 31, and there is a certain arc length between the first anti-rotation rib 32 and the second anti-rotation rib 33; Figure 5 As shown, a third anti-rotation rib 53 is provided on the inner sidewall of the outer casing 5, and the third anti-rotation rib 53 is located between the first anti-rotation rib 32 and the second anti-rotation rib 33; as Figure 7 and Figure 8 As shown, when the outer casing 5 is rotated clockwise to a certain angle, the pusher head 4 moves downward along the guide slope 51, and the third anti-rotation rib 53 abuts against the first anti-rotation rib 32. At this time, the pusher head 4 presses against the rubber head 1, and the dropper is in the closed state; Figure 6 and Figure 9 As shown, when the outer shell 5 is rotated in the opposite direction (counterclockwise) to a certain angle, under the elastic action of the rubber head 1, the push head 4 moves upward along the guide slope 51 and extends out of the opening 54. The third anti-rotation rib 53 abuts against the second anti-rotation rib 33. At this time, the push head 4 releases the rubber head 1, the tube body 2 absorbs liquid, and the dropper is in a ready-to-use state.
[0034] In a preferred embodiment, the lower inner side of the threaded cap 3 is provided with an internal thread 34; it also includes an outer bottle 6, the upper end of which is provided with an external thread 61, which is screwed to the internal thread 34; when the dropper is in the ready-to-use state and the outer shell 5 continues to rotate in the opposite direction, the third anti-rotation rib 53 drives the second anti-rotation rib, causing the outer shell 5 to drive the threaded cap 3 to rotate, 33 the external thread 61 separates from the internal thread 34, the dropper detaches from the outer bottle 6, and the dropper changes from the ready-to-use state to the use state. That is, through continuous reverse rotation, the dropper can successively complete the actions of drawing liquid and detaching from the outer bottle 6, improving the ease of operation of the dropper.
[0035] In a preferred embodiment, the inner sidewall of the threaded cap 3 is further provided with two opposing longitudinal grooves 35, and the outer periphery of the push head 4 is provided with two locking blocks 42. The locking blocks 42 slide up and down within the longitudinal grooves 35 to further restrict the up and down sliding of the push head 4.
[0036] In a preferred embodiment, the upper end of the outer shell 5 is provided with an opening 54, and the push head 4 is movably connected to the opening 54. The push head 4 can protrude upward from the opening 54, making it easy for the user to identify whether the dropper is in the ready-to-use state. When not in use, the push head 4 can also be hidden inside the outer shell 5.
[0037] In some embodiments, combined with Figure 2 , Figure 3 and Figure 9 The inner wall of the threaded cap 3 is provided with an annular hook 36, and the rubber head 1 is provided with an annular groove 11. The annular hook 36 is engaged in the annular groove 11, thereby fixing the rubber head 1 in the threaded cap 3.
[0038] In some embodiments, combined with Figure 3 and Figure 5 As shown, a limiting ring 55 is provided on the inner side wall of the outer shell 5, and an annular groove 37 is provided on the outer side wall of the threaded cover 3. The limiting ring 55 is engaged in the annular groove 37 to limit the up and down movement of the outer shell 5, and the outer shell 5 can rotate relative to the threaded cover 3.
[0039] In a preferred embodiment, combined with Figure 5 and Figure 7 The bottom end of the guide slope 51 is connected to a lower plane 52. When the dropper is in the closed state, the guide rib 41 abuts against the lower plane 52; combined with Figure 5 and Figure 6 The upper end of the guide slope 51 is connected to the upper plane 56. When the dropper is in the ready-to-use state, the guide rib 41 abuts against the upper plane 56.
[0040] In a preferred embodiment, a decorative ring is also installed on the outer bottle 6.
[0041] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings under the inventive concept of this utility model, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
