Description

Technical Field

[0001] The invention relates to the technical field of cosmetic production, and in particular to a personal care product mixing device and a mixing method thereof. Background Art

[0002] Personal care products generally refer to cosmetics. Cosmetics refer to chemical industrial products or fine chemical products that are spread on any part of the human body surface, such as skin, hair, nails, lips and teeth, by smearing, spraying or other similar methods, in order to achieve the purpose of cleaning, maintenance, beautification, modification and change of appearance, or correction of human body odor and maintenance of good condition.

[0003] The origin of cosmetics can be traced back to primitive society. In recent years, with the advancement of science and technology and the improvement of people's living standards, more and more types of cosmetics have begun to appear, including protective, nourishing, and decorative. Cosmetics are generally prepared products, and multiple materials need to be mixed together during production. For liquid cosmetics, the commonly used method is basically to complete the mixing of multiple ingredients by stirring. After searching, the Chinese invention patent with announcement number CN108187540B discloses a liquid cosmetic mixing process processing system, including a tank body, a distillation module, a rotation module, a stirring module and an auxiliary material adding module, the tank body is used to hold the liquid raw material to be stirred, the liquid cosmetics are stirred in the tank body, and a feed port is opened on the side wall of the tank body; the distillation module is used to produce distilled water required for cosmetics, and uses hot steam to heat and keep the tank body warm; the rotation module uses the high-pressure water vapor generated when producing distilled water as power to drive the stirring module to rotate; the stirring module is located inside the tank body, and the stirring module is used to stir the liquid cosmetics; the auxiliary material adding module is installed on the stirring module, and the auxiliary material adding module uses the rotation of the stirring module to add auxiliary materials into the tank body.

[0004] As shown in the above patents, the current cosmetic stirring devices basically use external power to provide energy to drive the stirring mechanism to rotate, and the most typical method is to use a motor to drive the stirring mechanism to rotate. Although for some high-viscosity paste cosmetics, it may be inevitable to use external power for mixing, but for the mixing of liquid cosmetics, the use of external power will cause energy waste, which is not conducive to cost saving. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a personal care product mixing device and a mixing method thereof, which can effectively solve the problem of energy waste caused by using external power to mix liquid cosmetics in the prior art.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] A personal care product mixing device comprising:

[0008] An upper mixing barrel, wherein a main material box and an auxiliary material box are respectively installed on the top of the upper mixing barrel, at least two spiral tubes are installed on the inner top wall of the upper mixing barrel, the outer surface of the spiral tube is connected to the feed pipe, and a siphon tube is installed inside the auxiliary material box, and the outlet end of the siphon tube is connected to the feed pipe;

[0009] The lower mixing barrel is connected with the upper mixing barrel by an hourglass tube, a rotating shaft is vertically installed inside the hourglass tube, a rotating disk located at the bottom of the spiral tube is installed on the rotating shaft, and the rotating disk is located in the upper half of the hourglass tube, and a stirring mechanism working with the rotating shaft is installed inside the lower mixing barrel.

[0010] When mixing liquid cosmetic raw materials, first pour part of the raw materials into the auxiliary material box, the height of the liquid level should be lower than the top height of the siphon tube, and then pour the other raw materials into the main material box, and the raw materials begin to fall along the spiral tube, forming a fluid in the spiral tube. Since the pressure of the fluid is less than the pressure of the static liquid, and the greater the flow rate, the smaller the pressure, a negative pressure is formed at the connection between the feed tube and the spiral tube. Through the action of the siphon tube, the liquid in the auxiliary material box flows out and merges into the spiral tube and falls along the spiral tube together, achieving preliminary mixing. When the raw materials flow out from the bottom of the spiral tube, the liquid will impact the surface of the turntable. Since the liquid outflow route is inclined toward the turntable surface, it will exert a force on the turntable to cause it to rotate. Therefore, the turntable begins to rotate rapidly, and the shaft rotates at the same time, driving the stirring mechanism at the bottom of the lower mixing barrel to work to further mix the liquid falling into the lower mixing barrel, so that the product can be fully mixed.

[0011] Furthermore, at least three outlets are provided at one end of the feed pipe close to the spiral tube.

[0012] Furthermore, the spiral directions of the spiral tubes are the same, and the starting points of the spiral tubes are equidistantly distributed on the circumference.

[0013] Furthermore, a plurality of bearing plates are equidistantly mounted on the turntable, and the bearing plates are used to receive the impact of the liquid flowing out of the spiral tube.

[0014] Furthermore, a spinning disc is installed on the rotating shaft, and the spinning disc is located in the lower half of the hourglass tube.

[0015] Furthermore, a plurality of material dropping grooves distributed in a mesh shape are evenly arranged on the inner wall of the lower mixing barrel.

[0016] Furthermore, the stirring mechanism includes a lever installed at the bottom end of the rotating shaft, a plurality of horizontally slidable paddle plates are elastically installed on the inner wall of the lower mixing barrel, a paddle is installed on the upper surface of the paddle plate, and a paddle groove adapted to the lever is opened on the paddle plate, and the paddle groove enables the paddle plate to gradually move backward when the lever is rotated to the paddle plate position.

[0017] Furthermore, a horizontal guide rod is fixedly mounted on the inner wall of the lower mixing barrel, the rowing plate is movably sleeved on the guide rod, and a spring is also sleeved on the guide rod.

[0018] The present invention also provides a method for mixing personal care products, which is applied to the above-mentioned mixing device and comprises the following steps:

[0019] S1: First, fill the auxiliary material box with raw materials, and then put other raw materials into the main material box. The raw materials flow down along the spiral tube, and negative pressure is generated at the bottom of the feed tube, and the raw materials in the auxiliary material box are drawn out and mixed into the spiral tube to complete the initial mixing;

[0020] S2: The liquid flowing out from the bottom of the spiral tube hits the rotating disk to rotate the shaft, and the liquid gathers in the middle of the hourglass tube to achieve further mixing;

[0021] S3: The liquid falls onto the spinning disc and is thrown onto the inner wall of the lower mixing barrel by the rotating spinning disc, and flows down along the chute. The liquids intersect and merge while flowing in the chute, achieving mixing again;

[0022] S4: The shaft rotates, driving the stirring mechanism to further mix the raw materials entering the lower mixing barrel.

[0023] Compared with the prior art, the present invention realizes automatic mixing of liquid cosmetics by means of the gravitational potential energy of the falling liquid and the negative pressure effect of the fluid, without the need for external power, thus avoiding energy waste and saving costs. The mixing effect is improved through multiple mixing methods, thus ensuring product quality and being highly efficient and energy-saving. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The present invention will be further described below in conjunction with the embodiments.

[0035] Example

[0036] Reference Figure 1-7 , a personal care product mixing device, comprising:

[0037] An upper mixing barrel 2, the top of which is respectively provided with a main material box 3 and a subsidiary material box 4, which can be used to contain different liquid raw materials respectively, at least two spiral tubes 6 are installed on the inner top wall of the upper mixing barrel 2, the outer surface of the spiral tubes 6 is connected with a feed pipe 8, a siphon tube 5 is installed inside the subsidiary material box 4, and the outlet end of the siphon tube 5 is connected with the feed pipe 8.

[0038] When mixing liquid cosmetic raw materials, first pour part of the raw materials into the auxiliary material box 4, the height of the liquid level should be lower than the top height of the siphon 5, and then pour the other raw materials into the main material box 3, and the raw materials begin to fall along the spiral tube 6, forming a fluid in the spiral tube 6. Since the pressure of the fluid is lower than the pressure of the static liquid, and the greater the flow rate, the smaller the pressure, a negative pressure is formed at the connection between the feed tube 8 and the spiral tube 6. Through the action of the siphon 5, the liquid in the auxiliary material box 4 flows out and merges into the spiral tube 6 and falls together along the spiral tube 6, achieving preliminary mixing.

[0039] There are at least three outlets at one end of the feed pipe 8 near the spiral tube 6. Before the liquid flowing out of the auxiliary material box 4 flows into the spiral tube 6, it is divided by multiple outlets and refined, and after flowing into the spiral tube 6, it is distributed more evenly, thereby improving the mixing effect.

[0040] Reference Figure 1 The present invention also has a lower mixing barrel 1, and the upper mixing barrel 2 and the lower mixing barrel 1 are connected by an hourglass tube 7. When the liquid flowing down from the upper mixing barrel 2 passes through the neck portion in the middle of the hourglass tube 7, it is merged together, which has the effect of further mixing. A rotating shaft 12 is vertically installed inside the hourglass tube 7, and a rotating disk 9 located at the bottom end of the spiral tube 6 is installed on the rotating shaft 12, and the rotating disk 9 is located in the upper half of the hourglass tube 7. A stirring mechanism that cooperates with the rotating shaft 12 is installed inside the lower mixing barrel 1. Among them, the rotating shaft 12 can be installed by a mounting frame fixed on the inner wall of the hourglass tube 7. This is a common installation method and will not be described in detail here.

[0041] When the raw materials flow out from the bottom end of the spiral tube 6, the liquid will impact the surface of the turntable 9. Since the liquid outflow path is inclined toward the surface of the turntable 9, a force is applied to the turntable 9 to cause it to rotate. Therefore, the turntable 9 starts to rotate rapidly, and the shaft 12 rotates at the same time, driving the stirring mechanism at the bottom of the lower mixing barrel 1 to work to further mix the liquid falling into the lower mixing barrel 1, so that the product can be fully mixed.

[0042] It should be noted that the spiral directions of the spiral tubes 6 are the same, and the starting points of the spiral tubes 6 are equidistantly distributed on the circumference. When two or more spiral tubes 6 are provided, the spiral directions of each spiral tube 6 are set to be the same. When the liquid flowing out of each spiral tube 6 impacts the turntable 9, a torsional force in the same direction is applied to the turntable 9, thereby causing the turntable 9 to rotate at a faster speed, and avoiding the impact direction of each liquid being opposite, which causes the rotation state of the turntable 9 to be unstable.

[0043] Further, refer to Figure 4-5, multiple bearing plates 10 are installed at equal intervals on the turntable 9, and the bearing plates 10 are used to receive the impact of the liquid flowing out of the spiral tube 6. When the liquid flowing out from the bottom end of the spiral tube 6 impacts the surface of the turntable 9, the force that drives the turntable 9 to rotate is the friction between the liquid and the surface of the turntable 9, so the utilization rate of the kinetic energy contained in the liquid is low. Therefore, multiple bearing plates 10 are set on the turntable 9 to withstand the impact of the liquid, so that each piece of liquid can directly hit the bearing plates 10, and the turntable 9 will be subjected to a greater impact force, and the rotation speed will be faster, which can provide sufficient power for the stirring mechanism. Therefore, the setting of the bearing plates 10 can improve the utilization rate of the kinetic energy contained in the liquid and avoid energy waste.

[0044] Under normal circumstances, when the liquid raw materials after preliminary mixing fall from the hourglass tube 7 into the lower mixing barrel 1, most of the liquid falls directly vertically, so a throwing plate 11 is also installed on the rotating shaft 12, and the throwing plate 11 is located in the lower half of the hourglass tube 7. When the rotating shaft 12 rotates, the throwing plate 11 rotates with it, and the raw materials fall from the middle of the hourglass tube 7 and fall on the surface of the throwing plate 11. After the throwing plate 11 rotates and swings, the liquid is thrown out of the surface of the throwing plate 11 along the radial direction of the throwing plate 11, and then falls on the inner wall of the lower mixing barrel 1. The liquid will flow down along the inner wall of the lower mixing barrel 1 and finally fall back to the bottom of the lower mixing barrel 1. In the above-mentioned falling process, the raw materials will be scattered, which improves the mixing effect.

[0045] Further, refer to Figure 6 A plurality of troughs 14 are evenly arranged on the inner wall of the lower mixing barrel 1. The troughs 14 are evenly distributed on the inner wall of the lower mixing barrel 1 in a reticular manner. The liquid falling on the inner wall of the lower mixing barrel 1 will first slide down along the troughs 14. Since there are many intersections on the reticular troughs 14, the liquid sliding down will mix together after meeting at the intersections. The mixed liquid will continue to fall and further mix with the liquid in other troughs 14 at another intersection. After repeated encounters and merging in the troughs 14, the raw materials will eventually be mixed to a deeper degree.

[0046] Reference Figure 5-7 The stirring mechanism includes a lever 13 installed at the bottom end of the rotating shaft 12, and a plurality of horizontally slidable paddle plates 15 are elastically installed on the inner wall of the lower mixing barrel 1. A paddle 17 is installed on the upper surface of the paddle plate 15. A paddle groove 18 adapted to the lever 13 is opened on the paddle plate 15. The paddle groove 18 enables the paddle plate 15 to gradually move backward when the lever 13 is rotated to the position of the paddle plate 15.

[0047] A horizontal guide rod 16 is fixedly mounted on the inner wall of the lower mixing barrel 1 , and the rowing plate 15 is movably sleeved on the guide rod 16 , and a spring is also sleeved on the guide rod 16 .

[0048] The rowing plate 15 is elastically installed by the guide rod 16 and the spring. When the shaft 12 rotates, the lever 13 rotates with the shaft 12 as the center. When the lever 13 rotates to the side of the rowing plate 15, the end of the lever 13 begins to enter the groove 18. Figure 7 Since the shifting groove 18 is inclined, when the shifting rod 13 moves inside the shifting groove 18, the rowing plate 15 will gradually move backwards, driving the paddle 17 on the rowing plate 15 to shift the liquid inside the lower mixing barrel 1 backwards, so that the liquid cosmetics form turbulence inside the lower mixing barrel 1, thereby achieving the purpose of sufficient mixing and ensuring the mixing effect of the product.

[0049] The present invention also provides a method for mixing personal care products, which is applied to the above-mentioned mixing device and comprises the following steps:

[0050] S1: First, fill the auxiliary material box with raw materials, and then put other raw materials into the main material box. The raw materials flow down along the spiral tube, and negative pressure is generated at the bottom of the feed tube, and the raw materials in the auxiliary material box are drawn out and mixed into the spiral tube to complete the initial mixing;

[0051] S2: The liquid flowing out from the bottom of the spiral tube hits the rotating disk to rotate the shaft, and the liquid gathers in the middle of the hourglass tube to achieve further mixing;

[0052] S3: The liquid falls onto the spinning disc and is thrown onto the inner wall of the lower mixing barrel by the rotating spinning disc, and flows down along the chute. The liquids intersect and merge while flowing in the chute, achieving mixing again;

[0053] S4: The shaft rotates, driving the stirring mechanism to further mix the raw materials entering the lower mixing barrel.

[0054] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
