[0032] Example 1

[0033] A dispensing mechanism, as shown in Figure 1 , comprises a main body 1, a flexible piece 2, an inlet valve piece 3, a sleeve piece 5 and an outlet valve piece 6.

[0034] The main body 1 and the flexible member 2 are connected to each other, and a dispensing chamber 4 is formed therebetween, the volume of which decreases as the flexible member 2 is deformed by being pressed downward, and increases as the flexible member 2 returns to its original shape.

[0035] For example, a seat groove 11 is formed on the outer periphery of the main body 1, and correspondingly, a fastening seat 21 is formed on the outer periphery of the flexible member 2, which cooperates with the seat groove 11. The seat groove 11 comprises a fixed inner wall 12 and a movable outer wall 13, the movable outer wall 13 has the ability to move or deform radially inward, so as to press and seal the fastening seat 21. The movable outer wall 13 is formed in a concentric manner around the outer periphery of the fixed inner wall 12, and the seat groove 11 is formed by the annular space defined by the fixed inner wall 12 and the movable outer wall 13. When the fastening seat 21 of the flexible member 2 is inserted into the seat groove 11, and the main body 1 is installed into the fluid product reservoir, the movable outer wall 13 moves or deforms radially inward, so as to press and seal the fastening seat 21.

[0036] A feeding passage 14 is formed in the center of the main body 1 and communicates with the dispensing chamber 4, the lower end of the feeding passage 14 extends downward and protrudes from the bottom surface of the main body 1. Compared with the prior art, by arranging the feeding passage 14 in the center of the main body 1, the cross-sectional area of the feeding passage 14 can be smaller, so when the dispensing mechanism extends the channel for liquid absorption in the direction of the fluid product liquid surface in the fluid product reservoir, the volume of the channel only increases a small amount, so that only a few press times are needed to make the dispensing chamber 4 absorb the fluid product during use, achieving the effect of quickly pumping out the fluid product. In addition, the dispensing chamber 4 can also absorb the fluid product at a lower position in the fluid product reservoir through the feeding passage 14, thereby reducing the residue in the fluid product reservoir.

[0037] As shown in Figure 2 The flexible member 2 further comprises a top cover 22 and a deformation body 23 connected between the fastening seat 21 and the top cover 22, and the flexible member 2 further comprises a discharge port 24 formed in the top cover 22, which communicates with the dispensing chamber 4. The top cover 22 is generally horizontally arranged in a disc-shaped structure, the deformation body 23 is generally conical and its small-diameter end is connected to the edge of the top cover 22, and a thin-walled area of the flexible member 2 is formed at the connection between the top cover 22 and the deformation body 23. Among them, the "thin-walled area" refers to the area of the flexible member 2 that deforms first under the action of downward external force, for example, the thin-walled area is configured to be smaller in thickness, so that the flexible member 2 can deform first at the thin-walled area when subjected to force.

[0038] For example, the thin-walled region is formed by opening a circumferentially continuous annular groove 231 on the outer side at the position where the top cover 22 is connected to the deformation body 23, as shown in Figure 2 Alternatively, as shown in Figure 3 the thin-walled region is formed by opening a circumferentially continuous annular groove 231 on the inner side at the position where the top cover 22 is connected to the deformation body 23. Alternatively, as shown in Figures 4-5 the thin-walled region is formed by opening a plurality of discontinuous grooves 232 on the inner and outer sides at the position where the top cover 22 is connected to the deformation body 23. It is easily understood that in other preferred embodiments, the annular groove 231 can also be opened on both the inner and outer sides at the position where the top cover 22 is connected to the deformation body 23; the discontinuous grooves 232 can also be opened only on the inner side or only on the outer side at the position where the top cover 22 is connected to the deformation body 23.

[0039] In this embodiment, the deformation body 23 is configured to be close to vertical, so that the diameter of the deformation body 23 can be reduced without changing the volume of the dispensing chamber 4, thereby facilitating the reduction of the diameter of the fluid product dispenser. In addition, by reducing the taper of the deformation body 23, when the deformation body 23 deforms at the "thin-walled region", the connection between the deformation body 23 and the top cover 22 is more likely to descend vertically and intrude into the dispensing chamber 4, reducing the radial swing (i.e. skew) of the deformation body 23 after deformation, so that the deformation body 23 is more likely to remain vertical, the top cover 22 is more likely to remain horizontal, and the dispensing mechanism is less likely to skew in the natural state, thereby improving the stability of the dispensing mechanism.

[0040] The inlet valve 3 is arranged axially movably relative to the dispensing chamber 4.

[0041] The lower end of the sleeve 5 is fixed to the top of the flexible member 2 (top cover 22), and the inside of the sleeve 5 forms a discharge passage 51 for communicating with the discharge port 24. The outlet valve 6 is arranged axially movably in the discharge passage 51, and the discharge passage 51 is provided with an outlet valve seat 52 adapted to the outlet valve 6. On the upper side of the outlet valve seat 52, the discharge passage 51 is further provided with a second limiting structure 53 for preventing the outlet valve 6 from leaving the discharge passage.

[0042] In this embodiment, the inlet valve 3 includes a movable member 31 in the form of a generally cylindrical column arranged axially, the lower end of the movable member 31 is arranged axially movably in the feed passage 14, the middle part of the movable member 31 is provided with a closure element 32, and the top of the movable member 31 is provided with a plugging element 33.

[0043] The sealing element 32 has a disc-shaped structure and is located inside the distribution chamber 4. When the flexible member 2 is deformed by a downward external force, the sealing element 32 can slightly descend and cover the top surface of the feed channel 14, thereby sealing the feed channel 14. The blocking element 33 is located on the outside of the distribution chamber 4, and a support 25 is provided at the outlet 24 of the flexible member 2. The blocking element 33 closes the outlet 24 by cooperating with the support 25.

[0044] When the flexible member 2 is subjected to a downward external force, the feed channel 14 is closed by the sealing element 32, the volume of the distribution chamber 4 decreases, and the blocking element 33 separates from the outlet 24. The fluid product in the distribution chamber 4 is squeezed, and under this squeezing action, the outlet valve 6 leaves the outlet valve seat 52, allowing the fluid product to be discharged. When the downward external force on the flexible member 2 disappears, the flexible member 2 springs back to its original position, the outlet valve 6 falls and closes the outlet channel 51, and a negative pressure is formed inside the distribution chamber 4. Under this negative pressure, the fluid in the fluid product storage is drawn into the distribution chamber 4 through the feed channel 14. When the flexible member 2 fully springs back to its original position, the blocking element 33 cooperates with the support seat 25 provided at the outlet 24 of the flexible member 2, thereby closing the outlet 24.

[0045] In addition, a first limiting structure 34 is provided between the lower end of the movable part 31 and the feed channel 14. This first limiting structure 34 is used to prevent the inlet valve 3 from continuing to move upward after the flexible part 2 has rebounded and reset, thereby ensuring that the blocking element 33 can close the outlet 24. In this embodiment, the first limiting structure 34 includes a groove provided on the lower side wall of the movable part 31 and a block provided on the side wall of the feed channel 14. The groove has a certain axial length so that the inlet valve 3 can move axially in the feed channel 14.
