The middle of the inner peripheral surface of the first connecting cover 21 is provided with a first sealing layer 24. The first movable shell 22 is located inside the upper cover 23 and above the first sealing layer 24. During the rotation of the upper cover 23, the first movable shell 22 moves toward the first sealing layer 24 and cuts through the first sealing layer 24. The bottom of the second connecting cover 31 is fitted and fixed on the outer peripheral surface of the upper cover 23. The middle of the inner peripheral surface of the second connecting cover 31 is provided with a third sealing layer 34. The second movable shell 32 is located inside the top cover 33 and above the third sealing layer 34. During the rotation of the top cover 33, the second movable shell 32 moves toward the third sealing layer 34 and cuts through the third sealing layer 34.

[0021] In the above technical solution: the upper cover 23 comprises an upper cover inner casing 25 and an upper cover outer casing 26, and the upper cover outer casing 26 is threadedly installed on the top of the outer circumferential surface of the first connecting cover body 21. The upper cover inner casing 25 is located in the first connecting cover body 21, the first movable casing 22 is located in the upper cover inner casing 25, and a first limiting structure is arranged between the upper cover inner casing 25 and the first movable casing 22. The first movable casing 22 is threadedly connected with the inner circumferential surface of the first connecting cover body 21, and the pitch of the thread between the upper cover outer casing 26 and the first connecting cover body 21 is greater than the pitch of the thread between the first movable casing 22 and the first connecting cover body 21. The bottom of the first movable casing 22 is provided with a first conical spike block 27, and the first conical spike block 27 is located above the first sealing layer 24. The top of the upper cover 23 is provided with a second sealing layer 28, and the first storage cavity is formed between the second sealing layer 28 and the first sealing layer 24.

[0022] In the above technical solution: the upper cover 23 comprises an upper cover inner casing 25 and an upper cover outer casing 26, and the upper cover outer casing 26 is threadedly installed on the top of the outer circumferential surface of the first connecting cover body 21. The upper cover inner casing 25 is located in the first connecting cover body 21, the first movable casing 22 is located in the upper cover inner casing 25, and a first limiting structure is arranged between the upper cover inner casing 25 and the first movable casing 22.

The top of the upper cover 23 is provided with a second sealing layer 28, and the first storage cavity is formed between the second sealing layer 28 and the first sealing layer 24.

[0023] When the second connecting cover body 31 is rotated, the upper cover 23 is synchronously rotated, and the first limiting structure enables the first movable casing 22 to be synchronously rotated with the upper cover 23. Since the pitch of the thread between the upper cover outer casing 26 and the first connecting cover body 21 is greater than the pitch of the thread between the first movable casing 22 and the first connecting cover body 21, the first movable casing 22 can be moved downward with the rotation of the upper cover 23, the first conical spike block 27 breaks the first sealing layer 24, and the solute in the first storage cavity falls and mixes with the solvent in the bottle body. When the top cover 33 is rotated, the second limiting structure enables the second movable casing 32 to be synchronously rotated with the top cover 33. Since the pitch of the thread between the top cover outer casing 36 and the second connecting cover body 31 is greater than the pitch of the thread between the second movable casing 32 and the second connecting cover body 31, the second movable casing 32 can be moved downward with the rotation of the top cover 33, the second conical spike block 37 breaks the third sealing layer 34 and the second sealing layer 28 in sequence, and the solute in the second storage cavity falls through the first storage cavity and falls into the bottle body, and mixes with the solvent in the bottle body.
