[0023] like Figure 1-Figure 2 As shown, the bracket assembly 3 includes a bottom plate 31, the upper surface of the bottom plate 31 is fixedly connected to a top plate 32 via a vertical rod, a plurality of through holes 33 for inserting the test tubes 4 are provided on the side of the top plate 32, and a positioning groove 34 is provided on the upper surface of the bottom plate 31 and below each through hole 33.

[0024] The test tube 4 can be fixed by providing the through hole 33 and the positioning groove 34 . When placing the test tube 4 , the test tube 4 is inserted into the through hole 33 , and the bottom end of the test tube 4 is located inside the positioning groove 34 .

[0025] like Figure 2 As shown, the top output shaft of the servo motor 5 is fixedly connected to the lower surface of the bottom plate 31 .

[0026] After the bottom plate 31 is driven to rotate by the servo motor 5 , the multiple test tubes 4 can be rotated by a specified angle each time, so that each test tube 4 is rotated to the bottom of the liquid storage assembly 7 in turn.

[0027] like Figure 1-Figure 4 As shown, the liquid storage assembly 7 includes a liquid storage box 71, a detachable top cover 72 is fixed on the top of the liquid storage box 71, a dropper 73 is passed through and fixedly connected to one side of the top cover 72, one end of the dropper 73 located in the liquid storage box 71 extends to the bottom of the liquid storage box 71, and the other end of the dropper 73 is located just above the test tube 4, and an air intake pipe 74 is fixedly connected to one side of the top cover 72, and the inflation assembly 8 includes a transverse tube 81 and an electric telescopic rod 82 fixed to the inner wall of the box body 1, a piston 83 is slidably connected inside the transverse tube 81, and the telescopic end of the electric telescopic rod 82 is fixedly connected to the piston 83, and a side wall of the transverse tube 81 away from one end of the electric telescopic rod 82 is fixedly connected to an exhaust pipe 84 and an exhaust pipe 85, and a hose 9 is commonly sleeved on the surface of the exhaust pipe 85 and the intake pipe 74. A one-way valve is fixedly connected to the middle of the exhaust pipe 84 and the exhaust pipe 85.

[0028] When the electric telescopic rod 82 is shortened to drive the piston 83 to move inside the transverse tube 81, air enters the transverse tube 81 from the exhaust pipe 84. When the electric telescopic rod 82 is extended to drive the piston 83 to move inside the transverse tube 81, the air in the transverse tube 81 is squeezed out and enters the liquid storage box 71 along the exhaust pipe 85 and the hose 9. The cosmetic liquid in the liquid storage box 71 is squeezed out along the dripping tube 73. By controlling the extension stroke of the electric telescopic rod 82, the dripping amount can be accurately controlled.

The electric telescopic rod 82 drives the piston 83 to move a specified stroke in the transverse tube 81, squeezes the air in the transverse tube 81 into the liquid storage box 71, and squeezes the cosmetics in the liquid storage box 71 along the dropper 73, and the cosmetics will drip into the test tube 4 below. After the current test tube 4 has finished dripping, the servo motor 5 drives the support assembly 3 to rotate a specified angle, so that another test tube 4 rotates to the bottom of the dropper 73 to prepare for dripping, until all test tubes 4 have finished dripping. After each use, the hose 9 can be unplugged from the air inlet pipe 74, and then the liquid storage assembly 7 can be removed from the surface of the transverse plate 6 to clean and replace the cosmetics.
