[0069] Several embodiments of the present invention will now be described in detail with references to FIGS.
[0070] Referring to FIG. 2, FIG. 3 and FIG. 6 together, an apparatus 100 for regulating the flow rate of a liquid from a bottle provided in the embodiment of the present invention is now described. The apparatus 100 comprises a connecting seat 10 and an adjusting seat 20. The connecting seat 10 has a first end 101 and a second end 102, the first end 101 is used for connecting with the bottle body 200, and the second end 102 is arranged relative to the first end 101. The connecting seat 10 is provided with a first perforation 103, and one end of the first perforation 103 is used to communicate with the opening of the bottle body 200. The first perforation 103 is eccentrically arranged on the connecting seat 10. The adjusting seat 20 is used for adjusting the liquid flow rate of the bottle body 200. The adjusting seat 20 is rotably connected with the second end 102 of the connecting seat 10. The adjusting seat 20 is provided with a second perforation 201, the second perforation 201 is used for communicating with the other end of the first perforation 103. The second perforation 201 is eccentrically arranged on the adjusting seat 20. The adjusting seat 20 has a clamping jaw 25 that clamp in a strip-shaped hole 104 in the connecting seat 10. The strip-shaped hole 104 is round-shaped, and the circumference where the strip-shaped hole 104 is located is coaxially arranged with the connecting seat 10. The perpendicular distance between the first perforation 103 and the second perforation 201 and the axis of the connecting seat 10 is approximately equal. When the adjusting seat 20 rotates over the connecting seat 10, the second perforation 201 meet with the first perforation 103 and gradually align, so that through the relative rotation of the adjusting seat 20 and the connecting seat 10, the size of the area of the communicating part between the second perforation 201 and the first perforation 103 can be adjusted to facilitate the flow rate of the liquid paste. The connection stability between the adjusting seat 20 and the connecting seat 10 is maintained by using the clamping jaw 25 to clamp into the strip-shaped hole 104. This prevents the deformation of the position of the adjusting seat 20 near the second perforation 201 when the first perforation 103 is blocked. The gap between the connecting seat 10 and the adjusting seat 20 is avoided to prevent the liquid paste from entering the gap. The strip-shaped hole 104 is arc-shaped, and when the adjusting seat 20 is rotated relative to the connecting seat 10, the clamping jaw 25 can slide along the strip-shaped hole 104. During the rotation, the position of the second perforation 201 relative to the first perforation 103 changes from eccentric to co-centric, thus controlling the opening size for discharging the liquid.
