Description

Technical Field

[0001] This utility model relates to the field of microfluidics technology, specifically a microfluidic multiphase liquid mixing device for skin care product production. Background Technology

[0002] Skincare products are products that protect the skin. With the continuous progress of the social economy and the enrichment of material life, skincare products are no longer something that only the rich can afford. Nowadays, skincare products have entered ordinary people's homes. They play a great role in improving people's spirit and image. In the production process, skincare product raw materials need to be stirred and synthesized into a relatively stable emulsion.

[0003] The existing patent announcement number CN 220194640 U discloses a stirring device for skin care product production. This solution stirs the raw liquid by rotating blades, and then the cylinder drives the container to move. Under the obstruction of the obstruction ring, the raw liquid at different positions is mixed, thereby further improving the mixing efficiency and eliminating unmixed positions, thus improving the production quality and efficiency of the emulsion.

[0004] However, during the use of this device, the multiphase liquid mixing in skin care product production mainly relies on traditional mechanical stirring methods, which makes it difficult to guarantee the uniformity of mixing. This results in uneven composition of the skin care product concentrate, with the upper liquid being relatively sparse and the lower liquid being relatively viscous, which can easily lead to relatively poor production quality of skin care products and affect their absorption rate.

[0005] Based on this, a microfluidic multiphase liquid mixing device for skin care product production is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In one embodiment, such as Figures 1-5 As shown, the microfluidic multiphase liquid mixing device for skin care product production in this embodiment includes a mixing cylinder 1. A first feed pipe 2 is provided on the top of the mixing cylinder 1 near the right side. A second feed pipe 3 is provided on the surface of the mixing cylinder 1 near the first feed pipe 2. A third feed pipe 4 is provided on the surface of the mixing cylinder 1 at the bottom of the second feed pipe 3. A discharge pipe 5 is provided at the bottom of the mixing cylinder 1. Control valves 6 are provided on the surfaces of the first feed pipe 2, the second feed pipe 3, the third feed pipe 4 and the discharge pipe 5.

[0028] A fixing plate 7 is fixedly installed on the inner side of the mixing cylinder 1 near the top. A mixing channel 8 is fixedly installed at the bottom of the fixing plate 7. A support frame 9 is connected to the bottom of the mixing channel 8. The support frame 9 is fixedly connected to the inner wall of the mixing cylinder 1 on its periphery near the bottom. Multiple connecting ports are opened on the periphery of the mixing channel 8 near the top. An atomizing nozzle 18 is fixedly installed at the bottom of the discharge pipe 5. A mixing component is provided inside the mixing channel 8. An anti-backflow component is provided inside the discharge pipe 5 and at the top of the atomizing nozzle 18.

[0029] In this embodiment, the oil phase is input through the first feed pipe 2, and the aqueous phase and alkaline regulator are input through the second feed pipe 3 and the third feed pipe 4, respectively, and transported to the inside of the mixing cylinder 1. Through the arrangement of the mixing components, mixing channel 8 and support frame 9, the mixture is mixed and stirred, and the mixture at the bottom is transported to the top of the inner side of the mixing cylinder 1 through the mixing sleeve 8, thereby realizing the circulation mixing function of the mixture, improving the stirring and mixing efficiency, and having high practical value. The completed mixture is output through the discharge pipe 5 and the atomizing nozzle 18. After being atomized by the precision atomizing nozzle 18, it forms uniform microspheres and is collected in a pre-prepared container.

[0030] In one embodiment, such as Figure 2 As shown, the inner side of the fixed plate 7 is provided with a connecting hole through which the bottom end of the first feed pipe 2 can pass. The side of the first feed pipe 2 near the bottom end is fixedly connected to the inner side of the connecting hole. The oil phase conveyed by the first feed pipe 2 can be smoothly conveyed to the inner side of the mixing cylinder 1.

[0031] In one embodiment, such as Figure 2 and Figure 3 As shown, the mixing assembly includes a rotating rod 11, the top of which penetrates the inner side of the fixed plate 7 and is fixedly mounted with a drive gear 12. Rotating blades 13 are arranged around the rotating rod 11 and inside the mixing channel 8. Multiple first stirring elements 14 are arranged around the rotating rod 11 and at the bottom of the rotating blades 13. The first stirring elements 14 mix the liquid at the bottom of the mixing cylinder 1. The rotation of the rotating blades 13 causes the liquid at the bottom to be transported upward inside the mixing channel 8 and discharged through the connecting port on the surface of the mixing channel 8, thereby realizing the function of circulating mixing of the liquid.

[0032] In one embodiment, such as Figure 2 and Figure 3 As shown, a drive motor 10 for driving the rotating rod 11 is fixedly installed on the top of the mixing cylinder 1. The support frame 9 has a mesh structure around its sides. The drive motor 10 drives the rotating rod 11 to rotate, thereby avoiding manual rotation. The mesh structure of the support frame 9 allows the mixed liquid to fall smoothly into the bottom of the inner side of the mixing cylinder 1.

[0033] In one embodiment, such as Figure 2 and Figure 3 As shown, four driven gears 15 are rotatably arranged on the top of the fixed plate 7 and around the drive gear 12. A driven rod 16 is rotatably connected to the bottom of the fixed plate 7 and at the bottom of the driven gears 15. A second stirring element 17 is fixedly installed on the side of the driven rod 16. The mixture is stirred by the second stirring element 17 in multiple directions. In conjunction with the action of the first stirring element 14, the mixing effect of the device is improved.

[0034] In one embodiment, such as Figure 2 and Figure 3 As shown, the top end of the driven rod 16 is fixedly connected to the bottom end of the connected driven gear 15. The driven gear 15 and the driving gear 12 are meshed with each other, which increases the correlation between various components and reduces the cost of the device.

[0035] In one embodiment, such as Figure 4 and Figure 5 As shown, the anti-backflow assembly includes an annular block 19, which is fixedly connected to the inner wall of the discharge pipe 5. A sealing plate 20 is attached to the bottom of the annular block 19. Sliding rods 21 are fixedly installed on the top of the sealing plate 20 near the four corners. The top of each sliding rod 21 passes through the bottom of the annular block 19 and is fixedly installed with a sliding block 22. The mixed liquid is transported through the conveying pipe after mixing. Under the pressure of the mixed liquid, the sealing plate 20 slides downward, separating the sealing plate 20 from the annular block 19, so that the mixed liquid can be smoothly sprayed out through the atomizing nozzle 18 and the backflow of the mixed liquid can be avoided.

[0036] In one embodiment, such as Figure 4 and Figure 5 As shown, a sliding hole is provided on the inner side of the annular block 19 for the sliding block 22 to slide up and down. The diameter of the sliding block 22 is larger than the diameter of the sliding rod 21. A spring 23 for driving the sliding block 22 to rise is fixedly installed inside the sliding hole and located on the outer edge of the sliding rod 21. Through the setting of the sliding block 22 and the sliding hole, the sealing plate 20 can move stably and the sealing plate 20 is prevented from falling off.

[0037] The above embodiment discloses a microfluidic multiphase liquid mixing device for skin care product production. The device inputs an oil phase through a first feed pipe 2, and an aqueous phase and an alkaline regulator through a second feed pipe 3 and a third feed pipe 4, respectively, and delivers them to the inside of a mixing cylinder 1. A drive motor 10 starts working, driving a rotating rod 11 to mix the liquid at the bottom of the mixing cylinder 1 via a first stirring element 14. The rotating blade 13 causes the liquid at the bottom to be conveyed upwards within a mixing channel 8 and discharged through a connecting port on the surface of the mixing channel 8. A multi-directional second stirring element 17 further agitates the liquid, ensuring thorough mixing and enabling a circulating mixing function, thus improving mixing efficiency and practical value. The completed mixture is output through a discharge pipe 5 and an atomizing nozzle 18. After being atomized by the precision atomizing nozzle 18, uniform microspheres are formed and collected in a pre-prepared container. An anti-backflow component prevents backflow of the mixture, increasing the device's practicality.

[0038] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
