[0034] Please see Figures 1 to 4 As shown, this utility model discloses a flat brush with a valve, which includes:

[0035] In this embodiment of the invention, the applicator 10 is a flat sponge head, and the applicator 10 has an axially arranged through hole 11.

[0036] A neck sleeve 20 is hollow and has a sleeve section 21 at one end, which is flat and corresponds to the shape of the applicator head 10. The sleeve section 21 is for the applicator head 10 to fit into, while the other end forms a fitting section 22. The inner wall surface of the fitting section 22 is provided with an annular flange 221 and at least one protrusion 222, and the end edge of the fitting section 22 is extended outward to form an outer periphery 223.

[0037] A piston rod 30 has an axially extending groove 34 that communicates with the through hole 11. The piston rod 30 is formed by a flange plate 31 extending towards one end with a fixed section 32 and extending towards the other end with a rod body 33. The inner wall surface of the outer periphery 223 of the neck sleeve 20 abuts against the flange plate 31. The fixed section 32 is used to hold one end of the applicator head 10, and the outer edge of the fixed section 32 is extended with a first positioning part 321 and a second positioning part at intervals. 322, the annular flange 221 abuts against the lower edge of the first positioning part 321. At least one first positioning groove 3211 and one second positioning groove 3221 are respectively recessed around the first positioning part 321 and the second positioning part 322. The first positioning groove 3211 and the second positioning groove 3221 restrict and position the protrusion 222 to prevent the neck sleeve 20 from rotating relative to the piston rod 30. A stop ring 331 is provided around the outer surface of the rod body 33 near the flange disk 31.

[0038] A bushing 40 has an axially formed receiving groove 41 at one end, and the rod body 33 is fitted into the receiving groove 41. The bushing 40 has a shaft 42, one end of which tapers to form a ring bottom 43, and the outer edge of the other end expands to form a ring periphery 44. The inner bottom surface of the ring bottom 43 is provided with a conical ring protrusion 431, and at least one feed port 432 is formed on the periphery of the ring bottom 43. The feed port 432 communicates with the receiving groove 41. In addition, a limiting part 45 is provided on the inner wall surface of the shaft 42 near the feed port 432, and the limiting part 45 abuts against the outer wall surface of the rod body 33.

[0039] An elastic element 50 is sleeved on the rod body 33 of the piston rod 30 and located between the stop ring 331 and the limiting part 45.

[0040] See Figure 5 and Figure 6 As shown, this utility model is used in conjunction with an outer cap 60 and a bottle 70 containing cosmetic liquid. The inner wall of one end of the outer cap 60 is provided with a screw-in portion 61 and a pressing edge 62. One end of the bottle 70 is provided with an axial opening 71. The bushing 40 is fitted on the inner edge of the opening 71, so that the circumferential portion 44 abuts against the end face of the opening 71. The outer edge of the opening 71 is provided with a threaded portion 72, which is screwed into the screw-in portion 61 of the outer cap 60, so that the outer cap 60 covers the applicator head 10 and the neck sleeve 20.

[0041] In the unused state, the outer cap 60 is screwed tightly onto the bottle body 70. The threaded portion 72 of the bottle body 70 is screwed into the threaded portion 61 of the outer cap 60. The outer periphery 223 of the neck sleeve 20 is pressed against the pressing edge 62 of the outer cap 60, causing the outer periphery 223 to press against the circumferential portion 44 of the bushing 40. At the same time, the stop ring 331 compresses the elastic member 50. Thus, the rod 33 moves toward the ring protrusion 431 and forms a plug with the ring protrusion 431 to close the inlet 432, preventing the cosmetic liquid in the bottle body 70 from flowing out.

[0042] See Figure 7 and paired Figure 6 As shown, when a user wants to apply the cosmetic liquid, they first unscrew the outer cap 60. The stop ring 331 of the piston rod 30 is pushed by the elastic force of the elastic member 50, causing the piston rod 30 to move axially, so that the outer periphery 223 moves away from the circumferential portion 44 of the bushing 40, and the rod body 33 moves away from the ring protrusion 431. At this time, the cosmetic liquid in the bottle 70 can flow into the through groove 34 from each of the inlets 432, and flow out through the through hole 11. It can be used with the applicator head 10 to evenly apply it to the application area. Thus, through the operation of the piston rod 30, the bushing 40 and the elastic member 50, not only can the cosmetic liquid flow out evenly and quantitatively, but it can also effectively prevent the cosmetic liquid from leaking out, achieving an airtight effect and isolating the cosmetic liquid from air pollution.

[0043] Continue reading Figures 8 to 10 The second embodiment of this utility model is shown below. The difference between this embodiment and the first embodiment is that the applicator 10 is a flat brush. The applicator 10 has an applicator section 12 and a solidification section 13. Part of the applicator section 12 is exposed outside the neck sleeve 20. The solidification section 13 is provided with the through hole 11. A hollow column 323 extends from the fixed section 32 of the piston rod 30 along the direction of the through groove 34. The solidification section 13 of the applicator 10 is engaged with the fixed section 32 and sleeves the hollow column 323. The hollow column 321 is provided with a through hole 324. The through hole 324 is connected to the through groove 34 and the through hole 11. Since the neck sleeve 20 restricts the applicator 10, it forces the bristles to be squeezed and concentrated towards the center. This makes it difficult to dispense the cosmetic liquid when it is thick. At this time, the hollow column 323 can guide the cosmetic liquid through the through hole 324 to flow out, thus achieving the effect of convenient dispensing.

[0044] Furthermore, the applicator head 10 of this invention is a flat (slightly elliptical in cross-section) brush or sponge head. Therefore, when in use, its wide side can be used for quick application over a large horizontal area, while its narrow side can be used for small-area application or dotting for more delicate needs. This allows the applicator head 10 to meet the various needs of users in makeup and improve the convenience of makeup application.
