When the upper cover 2 moves downward, the inner cover 3 is pressed, and then the lower push rod 31 and the lower push plate 32 on the outer side of the lower push rod 31 are driven to move downward. Because the size of the lower push plate 32 is matched with the size of the top of the conical groove 41 in the inner part of the material bin 4, the force can be accurately transmitted to the bottom of the material bin 4 during the pressing of the lower push plate 32, and the material bin 4 is broken. This design not only realizes the rapid and effective solid-liquid mixing, but also is simple to operate, and the user only needs to simply rotate the upper cover 2 to complete the whole process, greatly improving the convenience and efficiency of use. At the same time, this structure also ensures the uniformity of solid-liquid mixing, and ensures the quality and effect of the product.
[0023] In this embodiment, the conical groove 41 is composed of two half shells, the bottom of the two half shells is provided with a breaking end 42, and the thickness of the connection between the breaking ends 42 is 0.1 mm. This design makes the material bin 4 easily broken from the breaking end 42 under the pressure of the lower push plate 32, and realizes the rapid and effective solid-liquid mixing. At the same time, the thickness of 0.1 mm not only ensures the breaking ease, but also ensures the structural integrity of the material bin 4 when not in use.
[0024] Specifically, the top outer side of the lower cover 1 is provided with an annular groove 13, the bottom of the upper cover 2 is provided with a limiting ring 21, the top of the limiting ring 21 is connected with the bottom of the upper cover 2 through a breakpoint structure, and the limiting ring 21 is located in the inner side of the annular groove 13. This structure design makes the upper cover 2 accurately positioned on the lower cover 1, and limits the rotation space of the upper cover 2 relative to the lower cover 1, and the limiting ring 21 is removed when mixing is needed.
[0025] Further, the outer side of the limiting ring 21 is connected with a pulling head 211, and the limiting ring 21 is provided with a breaking structure 212 at one end close to the pulling head 211, and the thickness of the breaking structure 212 is 0.1 mm. The design of the pulling head 211 facilitates pulling and dismounting the limiting ring 21, and the breaking structure 212 can be easily broken to facilitate dismounting of the limiting ring 21 when needed.
[0026] Further, the inner wall of the upper cover 2 is provided with an upper cover inner thread 23, the top of the lower cover 1 is provided with an outer thread and is screwed with the upper cover inner thread 23, the bottom inner wall of the lower cover 1 is provided with a lower cover inner thread 12, the lower cover inner thread 12 is screwed with the bottle mouth, and the structural size of the lower cover inner thread 12 is same as that of the upper cover inner thread 23.

The limiting ring 21 is provided with a breaking structure 212 at one end close to the pulling head 211, and the thickness is 0.1mm, which facilitates the user to easily break the limiting ring 21. The user rotates the upper cover 2, and since the inner wall of the upper cover 2 is provided with an upper cover inner thread 23, which is screwed with the outer thread at the top of the lower cover 1, the upper cover 2 will move downward during rotation. When the upper cover 2 moves downward, the inner cover 3 is pressed downward, thereby driving the lower push rod 31 and the lower push plate 32 on the outer side to move downward. The size of the lower push plate 32 is matched with the size of the top of the conical groove 41 in the material bin 4, so that the force can be accurately transmitted to the bottom of the material bin 4 during the pressing process of the lower push plate 32. When the material bin 4 is pressed by the lower push plate 32, it is broken from the breaking end 42, realizing the mixing of solid and liquid.
[0032] After the solid-liquid mixing is completed, the user can disassemble the lower cover 1, and conveniently connect the upper cover 2 with the bottle opening through the same thread structure size, and discard the lower cover 1 and the inner cover 3, thereby improving the portability.
[0033] The bottom of the lower cover 1 is connected with the outside of the bottle opening through the anti-theft ring 11, which increases the difficulty of opening the bottle cap and plays an anti-theft role. After the bottle cap is opened for the first time, the anti-theft ring 11 will leave obvious traces, which facilitates the consumer to identify whether the product has been illegally opened. The sealing gasket 22 continuously provides sealing performance, prevents the solid material from being damp or the liquid from leaking, and ensures the quality and safety of the product.
