[0036] For further information, see Figure 5 , Figure 7 and Figure 8The bottom of the mask essence storage bin 601 is connected to an essence outlet 6011, the bottom of the vitamin C powder storage bin 602 is connected to a vitamin C powder outlet 6021, the essence outlet 6011 is connected to a fluid delivery pump 14 through a hose, the bottom of the fluid delivery pump 14 is provided with an essence outlet 1401, the vitamin C powder outlet 6021 is connected to a powder delivery pump 15 through a hose, the bottom of the powder delivery pump 15 is provided with a vitamin C outlet 1501, the fluid delivery pump 14 and the powder delivery pump 15 are installed on a fixed plate 13; the inner top wall of the filling box 1 is installed with an electric telescopic rod 2 12, the bottom of the power output shaft of the electric telescopic rod 2 12 is fixedly arranged at the top center position of the fixed plate 13, and the inner top wall of the filling box 1 is provided with a positioning groove 1301 for convenient placement of the fixed plate 13.

[0037] Specifically, the bottom of the facial mask essence storage bin 601 and the vitamin C powder storage bin 602 are designed to be inclined structures, which can allow the facial mask essence storage bin 601 to flow into the essence outlet 6011 and be guided away by the fluid delivery pump 14, and allow the vitamin C powder storage bin 602 to flow into the vitamin C powder outlet 6021 and be guided away by the powder delivery pump 15. The fluid delivery pump 14 and the powder delivery pump 15 are installed on a fixed plate 13 and are driven by an electric telescopic rod 12, so that the fluid delivery pump 14 and the powder delivery pump 15 can move simultaneously.

[0038] For further information, see Figure 2 A powder storage bag 1101 is also provided in the inner bag of the mask packaging bag 11. The volume of the powder storage bag 1101 is smaller than the volume of the inner bag of the mask packaging bag 11. The interior of the mask packaging bag 11 corresponds to the essence output port 1401, and the interior of the powder storage bag 1101 corresponds to the vitamin C output port 1501.

[0039] Specifically, the facial mask packaging bag 11 can be produced in the previous production equipment, wherein the powder storage bag 1101 can be in the shape of a film, which serves to load the vitamin C powder, and the interior of the facial mask packaging bag 11 serves to load the facial mask essence.

[0040] For further information, see Figure 5 The inner top wall of the filling channel 2 is also equipped with multiple ultraviolet disinfection lamps 16.

[0041] Specifically, a plurality of ultraviolet disinfection lamps 16 are installed inside the filling channel 2, so that the loading environment of the mask essence and the vitamin C powder can be kept in a sterile state, thereby ensuring the safety of the product.

[0042] When the filling device of the present invention is used: The facial mask essence is input into the facial mask essence storage bin 601 through the feeding port 1 9 for temporary storage, and the vitamin C powder is input into the vitamin C powder storage bin 602 through the feeding port 2 10 for temporary storage; The facial mask packaging bag 11 is placed between the two fixed rails 501 of the packaging bag clamping assembly 5, and the electric telescopic rod 505 is started. The power output shaft of the electric telescopic rod 505 is close to the edge position of the facial mask packaging bag 11. When the power output shafts of the electric telescopic rods 505 facing each other are both in contact with the edge position of the facial mask packaging bag 11, the edge position of the facial mask packaging bag 11 is clamped. Then, the two servo motors 502 on the packaging bag clamping assembly 5 are started. The power output shaft of the servo motor 502 drives the double-threaded rod 5021 to rotate. The double-threaded rod 5021 rotates, and uses the two opposite threads on its surface to drive the two clamping vertical rods 504 with its thread sleeve to slide in a direction close to each other, thereby achieving the effect of driving the top of the facial mask packaging bag 11 to unfold (the unfolding effect is as shown in FIG. 2 ). Figure 2 As shown), it is convenient for subsequent filling; The conveyor belt 4 is started, and the conveyor belt 4 drives the multiple groups of packaging bag clamping components 5 on the top thereof to move toward the inside of the filling channel 2. When the packaging bag clamping components 5 carry the facial mask packaging bag 11 to the bottom of the electric telescopic rod 2 12, the electric telescopic rod 2 12 starts to push the fluid delivery pump 14 and the powder delivery pump 15 under the fixed plate 13 downward, and makes the essence delivery port 1401 under the fluid delivery pump 14 enter the opening of the facial mask packaging bag 11, and makes the vitamin C delivery port 1501 under the powder delivery pump 15 enter the opening of the powder storage bag 1101 (such as Figure 7 shown); The fluid delivery pump 14 and the powder delivery pump 15 are started. The fluid delivery pump 14 draws out the mask essence stored in the mask essence storage bin 601 through the essence outlet 6011 and the hose, and injects it into the mask packaging bag 11 through the essence outlet 1401. The powder delivery pump 15 draws out the vitamin C powder stored in the vitamin C powder storage bin 602 through the vitamin C powder outlet 6021 and the hose, and injects it into the powder storage bag 1101 through the vitamin C outlet 1501. When the facial mask packaging bags 11 on a group of packaging bag clamping components 5 are filled with facial mask essence and vitamin C powder, the fluid delivery pump 14 and the powder delivery pump 15 stop working, the power output shaft of the electric telescopic rod 2 12 is retracted, and the fluid delivery pump 14 and the powder delivery pump 15 are driven back to the initial position through the fixed plate 13, and the conveyor belt 4 continues to transport the next group of packaging bag clamping components 5 holding the facial mask packaging bags 11 to the bottom of the electric telescopic rod 2 12 for subsequent filling; The mask packaging bag 11 filled with the mask essence and vitamin C powder is output from the other side of the filling box 1 through the transmission of the conveyor belt 4, and enters the subsequent sealing, packaging bag disinfection, and packaging process; It should be noted that before the facial mask packaging bag 11 enters the filling box 1, the non-woven fabric substrate can be first filled into the facial mask packaging bag 11 through the equipment, or the non-woven fabric substrate can be filled in the subsequent equipment after the facial mask essence and vitamin C powder are filled; It should also be noted that when the user uses the whitening and brightening facial mask, since the facial mask essence and vitamin C powder are packaged in the facial mask packaging bag 11, the unopened facial mask packaging bag 11 can be directly squeezed to rupture the powder storage bag 1101, causing the vitamin C powder in the powder storage bag 1101 to enter the facial mask packaging bag 11 and mix with the facial mask essence, which can be fully mixed by shaking. Alternatively, the facial mask packaging bag 11 can be opened first, and then the vitamin C powder in the powder storage bag 1101 can be scooped out with a spoon or other utensil, and added to the facial mask packaging bag 11 to shake and mix with the facial mask essence. When the vitamin C powder and the facial mask essence are mixed, they can be absorbed by the non-woven fabric substrate, and then the non-woven fabric substrate with the facial mask essence and vitamin C powder adhered to it can be taken out from the facial mask packaging bag 11 for use.

[0043] Test Example 1: The purpose of the test is to test the lightening of melanin by comparing the existing facial masks with vitamin C added in advance on the market with the whitening and brightening facial mask of Example 1 in which vitamin C powder is added to the facial mask essence when in use.

[0044] The test subjects were 60 subjects with no allergic symptoms on their faces and in good health. They first washed their faces with clean water and wiped them dry. Among them, 30 subjects applied a mask such as CN202322505145.4 and CN202321596035.7, in which vitamin C was added in advance, resulting in a wet vitamin C mask. The other 30 subjects applied a whitening and brightening mask formed by adding vitamin C powder to the mask essence in Example 1. The application time of the 60 subjects in the morning and evening was 15 to 20 minutes, and the cycle was one week. After the application cycle, the 60 subjects were summoned to measure the difference in skin melanin index and skin color of the 60 subjects by a photometer. The results are as follows: Example 1 Test Example 1 No lightening effect on melanin 0 people 22 people Mild lightening of melanin 8 people 6 people Moderate lightening of melanin 12 people 2 people The effect of reducing melanin is obvious 10 people 0 people As can be seen from the above table, in the whitening and brightening facial mask of the present invention, the vitamin C powder is not mixed with the mask essence when not in use, so that the vitamin C powder can always maintain the ability to lighten melanin, and the whitening and brightening facial mask has better effects of lightening melanin, whitening skin, lightening spots, moisturizing, shrinking pores, anti-wrinkle and firming than existing facial masks on the market, and can better enhance the effect of whitening and brightening the user's skin. That is to say, the vitamin C powder is mixed with the mask essence when used, which has a better ability to lighten melanin than mixing the vitamin C with the mask essence before use (during production).

[0045] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all changes within the meaning and range of equivalents of the claims be included in the invention.
