[0002] With the continuous improvement of the quality of life, people are paying more and more attention to the condition of their own skin, especially women. In order to avoid skin dehydration and aging, they need to apply essence and other skin care products for hydration and maintenance in daily life. However, the conventional smearing and patting method of hydration and absorption is not good and causes a lot of waste of hydrating nutrient solution. To solve this problem, some businesses have produced water light devices that are more effective in hydrating the skin.

The front end of the fourth spring 21 is fixedly connected to the inner wall of the hyaluronic acid analyzer 3. The mounting frame 18 is pulled outward by the pull rod 22, and the mounting frame 18 synchronously drives the wire barrel 19 to move, so that the bottom end of the liquid extraction tube 2 will move upward. At this time, it is only necessary to tilt the body of the essence bottle so that the bottom end of the liquid extraction tube 2 is inserted from the bottle mouth of the essence bottle, thereby completing the replacement of the essence bottle.

[0042] Working principle: when the essence bottle needs to be replaced, the cover plate 7 is opened, and then the essence bottle is taken out of the bottling cavity 4, and the ejection assembly will eject the liquid extraction tube 2 outward, so that the bottom end of the liquid extraction tube 2 is tilted outward, or when the essence bottle is taken out of the bottling cavity 4, the lifting assembly will pull the liquid extraction tube 2 upward, so that the liquid extraction tube 2 can be avoided by hand, thereby completing the replacement of the essence bottle;

[0043] The ejector assembly works as follows:

[0044] The first method is that after the essence bottle is installed, the first elastic cord 8 is stretched and tightly attached to the body of the essence bottle. After the essence bottle is taken out, the first elastic cord 8 acts on the liquid extraction tube 2, so that the bottom end of the liquid extraction tube 2 is tilted outwards.

[0045] Second, after the essence bottle is installed, the second elastic cord 10 is stretched so that the wrapping belt 9 is tightly attached to the body of the essence bottle. After the essence bottle is taken out, the elastic force of the second elastic cord 10 acts on the wrapping belt 9, and the wrapping belt 9 pushes the liquid extraction tube 2 out, so that the bottom end of the liquid extraction tube 2 is tilted outwards;

[0046] The third method is that after the essence bottle is installed, the first spring 12 is stretched so that the push plate 11 is tightly attached to the body of the essence bottle. After the essence bottle is taken out, the elastic force of the first spring 12 acts on the push plate 11, and the push plate 11 pushes the liquid extraction tube 2 out, so that the bottom end of the liquid extraction tube 2 is tilted outwards.

[0047] The fourth method is that after the essence bottle is installed, the ring 15 is pressed between the positioning tube 5 and the essence bottle. After the essence bottle is taken out, the elastic force acts on the fixing plate 13, the fixing plate 13 rotates outward, and then the liquid extraction tube 2 is pushed out through the ring 15, so that the bottom end of the liquid extraction tube 2 is tilted outward.

[0048] The pull component works as follows:

[0049] The mounting frame 18 is pulled outward by the pull rod 22, and the mounting frame 18 simultaneously drives the cable bundle 19 to move, so that the bottom end of the liquid extraction tube 2 will move upward. At this time, it is only necessary to tilt the essence bottle body so that the bottom end of the liquid extraction tube 2 is inserted from the bottle mouth of the essence bottle, thereby completing the replacement of the essence bottle.
