[0074] like Figure 7 As shown in Example 2, the brush portion 4 can be made of a soft brush head made of a sponge material without bristles or a silicone material.

[0075] In this embodiment, the bristle-free soft brush head can clean the inner wall of the cup and bottle more gently. Compared with bristles, the sponge material is softer and will not scratch or damage the surface of the cup and bottle, and is suitable for various cup and bottle materials; the soft brush head can better absorb and release detergents or soapy water, and the porous structure of the sponge can effectively absorb stains and odors, so that the detergent can fully play its role; the soft brush head is also elastic and adaptable, and can better fit the inner wall surface of the cup and bottle, clean more corners and hard-to-reach areas, and can more comprehensively remove stains and residues; the bristle-free sponge soft brush head also has good durability and is easy to clean. It can be reused and is easy to clean and disinfect to ensure hygiene and health.

[0076] During use, the first connecting rod 21 is pushed downward by sliding the handle 22, so that the first brush head 41 and the second brush head 42 move closer to each other and merge to form an integral brush head, and then the brush part 4 can be extended into the interior of the cup or bottle through the bottle mouth; then the handle 22 is slid reversely by hand to make the first connecting rod 21 make an upward contraction movement in the grip 1. At this time, the first connecting rod 21 drives the opening and closing mechanism 3 to open, so as to prop the first brush head 41 and the second brush head 42 to move away from each other and open, so that the bristles of the first brush head 41 and the second brush head 42 can better clean the inner wall surface of the cup or bottle, thereby improving the cleaning effect.

[0077] When the first link 21 moves upward, it drives the other end of the fourth link 34 and the other end of the fifth link 35 to move upward respectively. Since the second link 32, the fourth link 34 and the first link 21 form a triangle structure, and the third link 33, the fifth link 35 and the first link 21 form a triangle structure, when the other end of the four-link 34 and the other end of the fifth link 35 move upward, one end of the fourth link 34 and one end of the fifth link 35 move horizontally, and then the second link 32 and the third link 33 drive the first brush head 41 and the second brush head 42 of the brush part 4 to open outward.
