The number of the chute lower wall 111 and the protrusion can be one or more. In this embodiment, the number of the chute lower wall 111 and the protrusion is set to 4.

[0023] like Figure 1 and 2 As shown, the vacuum bottle with replaceable inner bottle of this embodiment further includes an outer ring 4, a head cap 2 and a pump core assembly 5. A through hole is provided in the middle of the outer ring 4, and the head cap 2 passes through the through hole to connect with the pump core assembly 5; Fig. 9 As shown, the head cap 2 is provided with a head cap liquid inlet 23 and a head cap liquid outlet 21, and the head cap liquid inlet 23 is connected to the liquid outlet of the pump core assembly 5. Fig.10 As shown, the outer ring side is provided with an outer cover notch 41, and the head cap liquid outlet 21 is located in the outer cover notch 41. When the outer ring 4 is rotated, the head cap 2 is driven to rotate. Of course, the outer ring 4 and the head cap 2 can also be set as one body. In this case, when the head cap 2 is pressed, the outer ring 4 and the head cap 2 move downward together, and when the outer ring 4 is rotated, the head cap 2 and the outer ring 4 rotate together. Fig.11 As shown, a retreat hole 42 is provided at the bottom of the outer ring 4. Fig.16 As shown, the upper part of the shell 8 is provided with a retreat wing 81, as shown in FIG. Fig.12 and 13 As shown, a large circle side hole 62 is provided around the top surface of the large circle 6, and the retreat wing 81 can pass through the large circle side hole 62 and enter the retreat hole 42.

[0024] The pump core assembly 5 is mounted to the outer bottle mouth through the large ring 6. Fig.12 and 13 As shown, a large circle limit block 61 is provided on the top surface of the large circle 6. Fig. 9 As shown, a head cap stopper 22 is provided at the bottom of the head cap 2. When the head cap stopper 22 is located on the large circle stopper 61, the head cap 2 cannot be pressed down; when the head cap stopper 22 avoids the large circle stopper 61, the head cap 2 can be pressed down. And when the head cap stopper 22 avoids the large circle stopper 61, the retreat wing 81 can pass through the large circle side hole 62 and enter the retreat hole 42. The large circle 6 and the pump core assembly 5 can also be integrally formed.

[0025] If the inner bottle 13 is disposable, a plug 12 is installed at the inner bottle opening in order to seal the cosmetics in the inner bottle 13. Figure 8 As shown, the plug 12 has a raised top and has a weak point 121 , and the plug 12 can be punctured by the pump core assembly 5 through the weak point 121 .

[0026] like Figure 1 and 2 The vacuum bottle with replaceable inner bottle of this embodiment further comprises a press cap 1, a cover sheet 3, a pump sleeve 7, a large piston 15 and a bottom cover 16. The top of the head cap 2 can be a detachable structure, that is, the top of the head cap 2 is set as a press cap 1. The cover sheet 3 is installed on the top of the outer ring 4. The pump sleeve 7 is sleeved on the upper part of the outer bottle 14. The large piston 15 is installed on the lower part of the inner bottle 13, and the bottom cover 16 covers the bottom of the inner bottle 13.

[0027] The preferred working principle of the vacuum bottle with replaceable inner bottle of this embodiment is as follows: like Figure 4 As shown, when the vacuum bottle with replaceable inner bottle is unlocked, that is, the head cap can be pressed, the inner bottle is pushed in from the bottom of the outer bottle. Figure 3 and 15 As shown, the protrusion on the inner bottle slides into the slide slot from the slide slot entrance 200, and the protrusion slides along the slide slot to drive the rotating sleeve to rotate; at the same time, the inner bottle moves upward, and since the retreat wing of the elastic sleeve can enter the retreat hole at this time, the inner bottle pushes the elastic sleeve to move upward, and the elastic sleeve compresses the spring; the end of the pump core assembly pierces the blockage and enters the inner bottle. Figure 5 and 15 As shown, the protrusion reaches the high point 101 of the upper wall of the chute, and the protrusion no longer slides. The inner bottle moves downward under the action of the spring, and the protrusion falls back to the low point 112 of the lower wall of the chute. Figure 6 As shown, the inner bottle is installed and the head cap can be pressed to pump out the cosmetics in the vacuum bottle.

[0028] When the cosmetics in the inner bottle are used up and need to be replaced, Figure 5 As shown, press the bottom of the inner bottle, as shown Figure 3 and 15 As shown, the protrusion on the inner bottle slides along the slide groove; the protrusion slides to the high point 101 on the upper wall of another slide groove and stops sliding. Under the action of the spring force, the elastic sleeve pushes the inner bottle downward, and the protrusion moves downward from the slide groove outlet 300, and the inner bottle exits.

[0029] like Figure 7 As shown, when the head cap limit block is located on the large circle limit block, the head cap cannot be pressed down, and the vacuum bottle is locked at this time; and at this time, the withdrawal wing of the elastic sleeve does not correspond to the withdrawal hole at the bottom of the outer circle, and the withdrawal wing is limited by the bottom of the large circle and cannot move upward. At this time, the inner bottle cannot be pushed upward, so the inner bottle is also locked and cannot be replaced.

[0030] Based on the description of the preferred embodiments of the present invention, it should be clear that the present invention defined by the attached claims is not limited to the specific details set forth in the above description, and many obvious changes to the present invention that do not depart from the spirit or scope of the present invention may also achieve the purpose of the present invention.
