Description

Technical Field

[0001] The present invention relates to a production process of an amino acid moisturizing and cleansing cream containing multifunctional auxiliaries. Background Art

[0002] With the accelerating pace of life and work of urban populations in recent years, problems such as skin sensitization and premature aging caused by unhealthy living habits such as staying up late and irregular diet have become increasingly serious. As a widely promoted daily chemical product, facial cleanser has a huge market demand and sales volume. However, the choice of facial cleanser categories is often a big problem for most people with sensitive skin. At present in the market, facial cleansers with amino acid surfactant ingredients are widely praised and widely concerned by consumers because they are closer to the pH value of the human epidermal sebum membrane, mild to use, non-allergenic, and have good cleaning power.

[0003] Amino acid surfactants (such as potassium cocoyl glycinate) are mild in themselves, but may have weak cleaning power and tend to result in a thin formula or insufficient foam when used alone. The addition of auxiliaries can: improve the use experience (such as thickening and foaming). Reduce the tight feeling after cleaning. Adapt to the needs of different skin types (such as anti-allergy ingredients for sensitive skin).

[0004] In the paper "Preparation and Performance Research of Amino Acid Facial Cleanser Containing Multifunctional Auxiliaries" published by Lin Jihui in the Journal of Yunnan Minzu University (Natural Sciences Edition) in May 2024, it is mentioned that: According to the formula with a total mass of 100 g, weigh the mass of deionized water required in the formula into a beaker, heat it to 70°C, add GCS-11, and continuously stir until all the powder is dissolved. Then add K12A and stir until completely dissolved. Then, under continuous stirring, add other main surfactants and co-surfactants. After reacting for 1 h and waiting for complete mutual solubility, take it out. Place it in a water bath at 40°C, add asiaticoside, ferulic acid extract, and other auxiliaries, and continuously stir to make it evenly mixed. Adjust the pH to the specified range for daily chemical products with citric acid or sodium hydroxide to obtain the facial cleanser sample. Patent with publication number CN117137817A: A residue-removing composition, an amino acid facial cleanser for sensitive skin and its preparation method. The preparation process is as follows: Mix the raw materials of component A in step (1), heat to 80 - 85°C and stir. After dissolving and mixing evenly, keep the temperature constant for 15 - 30 min, and continuously stir during the process; then cool down to 70 - 75°C and add the raw materials of component B, stir and mix evenly; then cool down to 60 - 65°C and add the raw materials of component C, stir and mix evenly; then cool down to 45 - 50°C and add the raw materials of component D, stir and mix evenly; then cool down to 38 - 42°C and add the raw materials of component E, stir and mix evenly; finally, discharge to obtain the amino acid facial cleanser for sensitive skin. Patent with publication number CN116585209A: Add the first conditioning component, glycerol, and water into an emulsifying pan, heat up to 90 - 95°C, add coconut oil amino acid, and homogenize and disperse for 1 - 1.5 h. Then add citric acid and functional auxiliaries and stir for 2 - 8 min. After that, add a stabilizer, keep warm for 10 - 15 min, then stir for 10 - 30 min, add the second conditioning component, and stir for 10 - 20 min; then apply pressure, turn on the cooling water to cool the material. After the material cools down to 50 - 48°C, stop applying pressure, continue to stir and cool down to 45 - 40°C, then stop stirring, discharge and store until the consistency of the material is qualified, and then fill it. Currently, the preparation processes of existing technologies are basically heating, mixing, and stirring, cooling in stages (or not cooling) and adding subsequent materials and stirring several times (but the cooling temperature is different each time, and the added substances of subsequent materials are different). Such a process of multiple stirrings makes the preparation working hours longer and the efficiency lower. However, in the preparation process of facial cleanser, the materials are added and stirred in stages rather than all at once, mainly based on the following scientific and technological considerations in many aspects: 1. Ensure uniform dispersion and dissolution Solubility differences of different materials: The facial cleanser formula usually includes an aqueous phase (such as water, water-soluble moisturizers), an oil phase (such as oils and fats, emulsifiers), and active ingredients that may be incompatible (such as vitamins, plant extracts). Adding in stages can ensure that each ingredient is fully dissolved or dispersed under suitable conditions.

[0005] Avoid caking or aggregation: Certain ingredients (such as the thickener carbomer) may form gummy lumps that are difficult to disperse if directly poured into a large amount of water. It is necessary to premix with a small amount of water first.

[0006] 2. Control chemical reactions and stability pH sensitivity: Some ingredients (such as cleansing surfactants, acidic or alkaline regulators) need to be added at a specific pH.

[0007] Avoid ingredient interactions: Certain active ingredients (such as cationic conditioners and anionic surfactants) will precipitate when directly mixed. It is necessary to add them in stages or adjust the order.

[0008] 3. Optimize the emulsification process Emulsification efficiency: The oil phase and water phase usually need to be heated to similar temperatures (such as 70°C) separately before mixing. Stirring in stages can ensure the formation of a stable emulsion microstructure.

[0009] Shear force control: High-shear stirring is used for primary emulsification, while low-speed stirring may be required during the homogenization stage to avoid introducing too many bubbles.

[0010] So there is currently no good solution to solve this problem. Summary of the Invention

[0011] The purpose of the present invention is to overcome the defects existing in the prior art and provide a production process for an amino acid cleansing cream containing a multifunctional auxiliary agent. For the situation where multiple surfactants are gradually added to deionized water and stirred, homogenized, and emulsified, a small amount can be added each time, and it can be added in multiple times. Each time a small amount is added, but the addition ratio is added according to the ratio of each surfactant to water. Therefore, after each addition, a small amount of surfactant and water are stirred. In this way, since a small amount of solute is more easily surrounded by the solvent (water or oil), the intermolecular contact area increases, the diffusion path shortens, so the dissolution and dispersion are faster, and the total duration is shortened. Each stirring and homogenization space is not connected to each other and is independent. Stirring in multiple stirring and homogenization spaces simultaneously can further accelerate the process.

[0012] To achieve the above object, the technical solution of the present invention is to design a production process for an amino acid cleansing cream containing a multifunctional auxiliary agent, which consists of the following process steps: Stir, homogenize, and emulsify the surfactant and water, and then add the multifunctional auxiliary agent and continue to stir, homogenize, and emulsify; or first stir, homogenize, and emulsify the water and the auxiliary agent, then add the surfactant and continue to stir, homogenize, and emulsify, and then add the multifunctional auxiliary agent and stir, homogenize, and emulsify. The water is deionized water, and the surfactant is a composition of one or more of coconut amino acids, sodium cocoyl glycinate, or potassium cocoyl glycinate.

[0013] A further technical solution is that the multifunctional auxiliary agent is a mixture of chitosan oligosaccharide and gelatin, or the multifunctional auxiliary agent is dandelion extract, or the multifunctional auxiliary agent is asiaticoside and ferulic acid extract.

[0014] A further technical solution is that in the stirring, homogenizing and emulsifying process, the surfactant and water are stirred, homogenized and emulsified step by step in stages; or in the stirring, homogenizing and emulsifying process, the water and the auxiliary agent are stirred, homogenized and emulsified step by step in stages.

[0015] For the case of gradually adding deionized water to multiple surfactants for stirring, homogenizing and emulsifying, a small amount can be added each time and added in multiple times. Each time a small amount is added, but the addition ratio is added according to the ratio of each surfactant to water. Therefore, after each addition, a small amount of surfactant and water are stirred. In this way, since a small amount of solute is more easily surrounded by the solvent (water or oil), the intermolecular contact area increases and the diffusion path shortens, so the dissolution and dispersion are faster and the total duration is shortened. If the multifunctional auxiliary agent is also added subsequently at the temperature of the surfactant and water homogenizing and stirring, the multifunctional auxiliary agent, citric acid and stabilizer are also added in small amounts each time and added in multiple times. Each time a small amount is added, but the addition ratio is added according to the ratio of each surfactant, water, multifunctional auxiliary agent, citric acid, stabilizer, etc. If the stirring and homogenizing temperature of the multifunctional auxiliary agent is different from the stirring and homogenizing temperature of the surfactant, only for the multiple surfactants in the early stage, deionized water is gradually added in small amounts each time and added in multiple times. After all the surfactants are dissolved and dispersed, they are then transferred to a water bath at the set temperature, and the multifunctional auxiliary agent (the total amount) is added and then stirred and homogenized.

[0016] A further technical solution is that the mass parts of the addition amounts of the respective raw materials are as follows: 12 - 40 parts of surfactant, 30 - 80 parts of water, and 1 - 15 parts of multifunctional auxiliary agent.

[0017] A further technical solution is that the coconut oil amino acid is 25 - 30 parts; the sodium cocoyl glycinate is 1 - 12 parts; the potassium cocoyl glycinate is 9 - 32 parts.

[0018] A further technical solution is that in the stirring, homogenizing and emulsifying process, a homogenizing emulsifier is used. Inside the body of the homogenizing emulsifier, several partition plates are arranged from top to bottom to divide the inner cavity of the body into several independent stirring and homogenizing spaces. Corresponding to each stirring and homogenizing space on the body, there are a deionized water addition port, several surfactant addition ports, and several auxiliary agent addition ports. The inside of the body is partitioned into several independent stirring and homogenizing spaces by the partition plates. In each stirring and homogenizing space, a small amount of deionized water and surfactant are stirred and homogenized, so that the dissolution and dispersion speed in each stirring and homogenizing space is fast. And when they act together in each stirring and homogenizing space, the speed is further accelerated. Moreover, although they are stirred together in each stirring and homogenizing space, they still use the same stirring shaft, without increasing the structural complexity or the driving mechanism.

[0019] A further technical solution is that a stirring motor is arranged on the top of the machine body. The output shaft of the stirring motor is fixedly connected to a stirring shaft, and a homogenizing stirring blade is arranged on the stirring shaft. The stirring shaft passes through the partition plate and is rotationally and sealingly connected to the partition plate at the passing position. An outlet is arranged at the bottom of the machine body.

[0020] A cavity is arranged inside the side wall of the machine body. The cavity is in a U-shaped or semi-U-shaped form imitating the machine body. Inside and outside the cavity in the side wall of the machine body, an inner channel and an outer channel communicating with the cavity are respectively arranged. The inner channel communicates with the inner cavity of the machine body, and the outer channel opening of the outer channel is located on the outer surface of the machine body. A plurality of elastic air bags are arranged on the machine body. The number of elastic air bags is the same as that of the inner channel or the outer channel. One end of the elastic air bag is located in the inner channel, and the other end passes through the outer channel and is located outside the machine body. An elastic sheet is arranged in the inner channel. The elastic sheet is arranged near the channel opening of the inner channel close to the inner cavity of the machine body. One end of the elastic sheet is fixedly connected to the inner wall of the inner channel. A support ring restricting the deformation of the elastic sheet towards the inner cavity of the machine body is fixedly arranged on the inner side wall of the machine body. The middle part of the elastic air bag is sealingly and fixedly connected to the inner channel opening of the outer channel.

[0021] The inner channel opening of the outer channel is the connection part of the outer channel and the cavity, and the channel opening of the inner channel far from the inner cavity of the machine body is the connection part of the inner channel and the cavity. Both the outer channel and the inner channel are cylindrical channels.

[0022] All the elastic air bags are mutually communicated through a connecting pipe at the outer end of the outer channel. The connecting pipe is connected to an air pump; The bottom end of the connecting pipe is communicated with the lowermost elastic air bag, and the top end of the connecting pipe is communicated with the air pump through an air pipe. After such an arrangement, only by starting or stopping the air pump can all the elastic air bags be inflated or deflated simultaneously, so as to make the elastic air bags press or not press the elastic sheet. When the elastic sheet is pressed, the non-connection between the inner channel and the cavity is realized, and the stirring and homogenizing spaces inside the machine body are mutually independent, isolated and non-connected. When the elastic sheet is not pressed, the elastic sheet rotates outwards due to elasticity, realizing the connection between the inner channel and the cavity. In this way, after the stirring and homogenizing in each stirring and homogenizing space is completed, the various stirring and homogenizing spaces can be connected, and then by opening the outlet, the discharging of all the materials with completed stirring and homogenizing can be realized. The middle part of the elastic air bag being sealingly and fixedly connected to the inner channel opening of the outer channel can avoid the problem of leakage caused by the connection between the outer channel and the cavity. And only when the middle part of the elastic air bag is sealingly fixed (adhesive sealing can also be adopted) to the inner channel opening of the outer channel can the inflation expansion and deflation contraction of the elastic air bag not be interfered.

[0023] A linkage structure is provided inside the machine body to ensure that when the stirring shaft rotates, the stirring and homogenizing spaces are not connected to each other, while when the stirring shaft stops stirring, the stirring and homogenizing spaces are connected; the stirring shaft passes through the bottom of the machine body and extends beyond the machine body. The linkage structure includes an opening provided at the bottom end of the stirring shaft, and a rubber part is inserted into the opening in a matching manner; a gate valve is provided on the connecting pipe, a connecting rod is fixedly connected to the air pump, the connecting rod is fixedly connected to a rotating rod, the rotating rod is connected to a sleeve through a torsion spring, and the sleeve is fixedly connected to the handwheel of the gate valve; a rope is wound around the surface of the sleeve, one end of the rope is fixedly connected to the surface of the sleeve, and the other end is wound around the rubber part and then fixedly connected to the rubber part; the rubber part is composed of a cylindrical rubber rod and a pair of symmetrically arranged squares fixedly connected to one end of the rubber rod, and the central connection line of the two squares passes through the diameter of the rubber rod.

[0024] The connection between the stirring shaft and the machine body is rotationally sealed; the discharge port is avoided directly below the stirring shaft, that is, there is a distance between the central position of the discharge port and the rotation axis of the stirring shaft; one end of the torsion spring is fixedly connected to the rotating rod, and the other end is fixedly connected to the inner side wall of the sleeve. The central position of one end of the sleeve is provided with the aforementioned rotating rod, and the inner side wall of the other end is fixedly connected to the handwheel; the squares are also made of rubber material, but the elasticity of the squares is greater than that of the rubber rod, or in other words, the hardness of the squares is less than that of the rubber rod. After such a setting, when the stirring shaft rotates, since the rubber part is inserted into the opening, similar to the connection between a shaft and a key, the rubber part also rotates, so the rope is driven to drive the sleeve to rotate. Since the sleeve is fixedly connected to the handwheel, the handwheel rotates, realizing the opening of the gate valve. When the stirring shaft rotates, the gate valve automatically opens, and the air pump supplies air to the elastic airbag, realizing that the elastic sheet closes the inner channel. After the gate valve is opened to the maximum (that is, when the handwheel cannot be rotated any further), since the elasticity of the rubber rod is less than that of the squares, the squares deform, forming a situation where the stirring shaft rotates idly relative to the rubber part. The elasticity of this elastic part of the squares and the friction between the entire rubber part and the opening after the squares deform are still sufficient to overcome the torsion of the torsion spring, but cannot overcome the rotational power of the stirring shaft (when the stirring shaft starts to rotate, the rubber part rotates with the shaft, and when the force is large enough, the squares deform and start to rotate idly); when the stirring shaft stops rotating, due to the action of the torsion spring, the sleeve resets, and the rope winds in the reverse direction. At this time, since the stirring shaft no longer has a driving force, it becomes the rubber part driving the stirring shaft to rotate (at this time, the stirring shaft rotates idly relative to the stirring motor), and the reset of the sleeve realizes the closing of the gate valve. Then, the gas in the elastic airbag is insufficient and does not press against the elastic sheet, so the inner channel is connected to the cavity.

[0025] To prevent the rubber part from falling out of the opening, a folding rod is provided at the bottom end of the stirring shaft. After the rubber part is inserted into the opening, its lower end abuts against the folding rod. The folding rod can also be set in a way that two rods are hinged, and a fastening bolt is provided at the hinge. Before the rubber part is inserted, the fastening bolt is loosened, and after the rubber part is inserted into the opening, the folding rod is rotated and the fastening bolt is tightened.

[0026] When the stirring shaft rotates, each stirring and homogenizing space is independent and not connected to each other. When the stirring shaft stops stirring, each stirring and homogenizing space is connected. When the stirring shaft rotates, the cavity is closed. Once the stirring stops, the cavity is connected to the inner cavity of the machine body and is no longer closed, being in an open state. Through the linkage structure, the kinetic energy of the rotation of the stirring shaft itself is used to realize the automatic closing and connection of the cavity and the machine body.

[0027] The linkage structure includes a number of through holes provided on the partition plate. At each through hole on the partition plate, a rubber sleeve is fixedly connected. The rubber sleeve is arranged on the upper surface of the partition plate. The inner diameter of the rubber sleeve is larger than the aperture of the through hole. The height of the rubber sleeve satisfies that the upper end of the rubber sleeve extends beyond the lower end of the stirring blade in the corresponding stirring and homogenizing space. After such a setting, before adding the materials, first start the stirring motor to make the stirring shaft rotate. After reaching the rotational speed, due to the rotation of the stirring shaft, the lower end of the stirring blade presses the rubber sleeve. When reaching the set rotational speed (the rotational speed of homogeneous stirring is relatively high), the rubber sleeve is in a deformed and extruded state all the time, and the through hole is closed. Each stirring and homogenizing space is independent and not connected to each other. When the stirring stops, a part of the rubber sleeve (that is, the rubber sleeve not directly below the lowest end of the stirring blade) is no longer extruded, and the through hole in this part of the rubber sleeve is not closed, realizing the connection of the upper and lower stirring and homogenizing spaces. At this time, opening the discharge port can discharge all the materials after homogeneous stirring. The advantages and beneficial effects of the present invention are as follows: For the situation of gradually adding deionized water to multiple surfactants for stirring, homogenizing and emulsifying, it is possible to add a small amount each time and add it in multiple times. Each time a small amount is added, but the addition ratio is added according to the ratio of each surfactant to water. Therefore, after each addition, a small amount of surfactant and water are stirred. In this way, because a small amount of solute is more easily surrounded by the solvent (water or oil), the intermolecular contact area increases and the diffusion path shortens, so the dissolution and dispersion are faster, and the total duration is shortened. If the multifunctional auxiliary agent is also added subsequently at the temperature of homogeneous stirring of the surfactant and water, the multifunctional auxiliary agent, citric acid, and stabilizer are also added in small amounts each time and added in multiple times. Each time a small amount is added, but the addition ratio is added according to the ratio of each surfactant, water, multifunctional auxiliary agent, citric acid, stabilizer, etc.

[0028] The interior of the machine body is partitioned into several independent stirring and homogenizing spaces by a partition plate. In each stirring and homogenizing space, a small amount of deionized water and surfactant are stirred and homogenized respectively, so that the dissolution and dispersion speed in each stirring and homogenizing space is fast. When they act together in each stirring and homogenizing space, the speed is further accelerated. Moreover, although all the stirring and homogenizing spaces are stirred together, they still use the same stirring shaft, without increasing the structural complexity or the driving mechanism.

[0029] Just by starting or stopping the air pump, it is possible to simultaneously inflate or deflate all the elastic air bags, causing the elastic air bags to press against or not press against the elastic sheets. When the elastic sheets are pressed, the inner channels are disconnected from the cavity channels, making each stirring and homogenizing space in the machine body independent and isolated from each other and not connected. When the elastic sheets are not pressed, the elastic sheets rotate outward due to their elasticity, connecting the inner channels to the cavity channels. In this way, after the stirring and homogenizing in each stirring and homogenizing space is completed, the various stirring and homogenizing spaces can be connected, and then by opening the discharge port, the discharge of all the stirred and homogenized materials can be achieved. The middle part of the elastic air bag being sealed and fixedly connected to the inner channel opening of the outer channel can prevent the outer channel from being connected to the cavity channel and causing leakage problems, and only when the middle part of the elastic air bag is sealed and fixedly connected (adhesive sealing can also be used) to the inner channel opening of the outer channel can it not interfere with the inflation and expansion and deflation and contraction of the elastic air bag.

[0030] When the stirring shaft rotates, each stirring and homogenizing space is independent and not connected to each other. When the stirring shaft stops stirring, the various stirring and homogenizing spaces are connected. When the stirring shaft rotates, the cavity channel is closed. Once the stirring stops, the cavity channel is connected to the inner cavity of the machine body and is no longer closed but in an open state. Through the linkage structure, the kinetic energy of the rotation of the stirring shaft itself is used to achieve the automatic closing and connection of the cavity channel and the machine body.

Specific implementation mode

[0033] The following combines the drawings and embodiments to further describe the specific implementation mode of the present invention. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and cannot be used to limit the protection scope of the present invention.

[0034] Embodiment 1: The present invention is a production process of an amino acid cleansing and moisturizing cream containing a multifunctional auxiliary agent, which consists of the following technological steps: stirring, homogenizing and emulsifying the surfactant and water, and then adding the multifunctional auxiliary agent and continuing to stir, homogenize and emulsify; The water is deionized water, and the surfactant is a composition of one or more of coconut amino acids, sodium cocoyl glycinate or potassium cocoyl glycinate.

[0035] The stirring, homogenizing and emulsifying process adopts the method of stirring, homogenizing and emulsifying the surfactant and water in stages; or the stirring, homogenizing and emulsifying process adopts the method of stirring, homogenizing and emulsifying the water and the auxiliary agent in stages. Or the stirring, homogenizing and emulsifying process adopts the method of stirring, homogenizing and emulsifying the auxiliary agent and the surfactant in stages. Or the stirring, homogenizing and emulsifying process adopts the method of stirring, homogenizing and emulsifying the water, the auxiliary agent and the surfactant in stages.

[0036] The mass parts of the addition amounts of the respective raw materials are: 12-40 parts of surfactant, 30-80 parts of water, and 1-15 parts of multifunctional auxiliary agent.

[0037] The coconut amino acid is 25-30 parts; the sodium cocoyl glycinate is 1-12 parts; the potassium cocoyl glycinate is 9-32 parts.

[0038] The stirring, homogenizing and emulsifying process adopts a homogenizing emulsifier, such as Figures 1 to 5 shown (for the convenience of illustration, Figure 3Only the inner and outer channels of the right half of the cavity are shown, and the left half is not shown; and Figure 3 Only the top two elastic air bags are shown). Inside the body 1 of the homogeneous emulsifier, several partitions 3 are arranged from top to bottom to divide the inner cavity of the body into several independent stirring and homogenizing spaces 2. For each stirring and homogenizing space 2 on the body 1, a deionized water adding port 4, several surfactant adding ports 5, and several additive adding ports 6 are provided.

[0039] A stirring motor 7 is arranged at the top of the body 1. The output shaft of the stirring motor is fixedly connected to a stirring shaft 8. Homogenizing stirring blades 9 are arranged on the stirring shaft. The stirring shaft 8 passes through the partition 3 and is rotationally and sealingly connected to the partition at the passing position. An outlet 10 is arranged at the bottom of the body.

[0040] In this embodiment, the outlet 10 is arranged directly below the stirring shaft 8.

[0041] Add deionized water and surfactant in small amounts each time to achieve rapid dissolution and dispersion, so that the total dissolution and dispersion time is shortened; and each stirring and homogenizing space is not connected to each other and is independent. Stirring in multiple stirring and homogenizing spaces simultaneously can further accelerate the process.

[0042] A cavity 11 is arranged inside the side wall of the body. The cavity is in a U-shaped or semi-U-shaped form imitating the body. Inside the side wall of the body 1, an inner channel 12 and an outer channel 13 connected to the cavity are respectively arranged inside and outside the cavity 11. The inner channel 12 is connected to the inner cavity of the body 1. The outer channel opening of the outer channel 13 is located on the outer surface of the body 1. Several elastic air bags 14 are arranged on the body. The number of elastic air bags is the same as the number of the inner channels 12 or the outer channels. One end of the elastic air bag 14 is located in the inner channel 12, and the other end passes through the outer channel 13 and is located outside the body 1. An elastic sheet 15 is arranged inside the inner channel. The elastic sheet is arranged near the channel opening of the inner channel 12 close to the inner cavity of the body. One end of the elastic sheet is fixedly connected to the inner wall of the inner channel. A support ring 16 that restricts the deformation of the elastic sheet 15 towards the inner cavity of the body is fixedly arranged on the inner side wall of the body. The middle part of the elastic air bag 14 is sealingly and fixedly connected to the inner channel opening of the outer channel 13.

[0043] The inner channel opening of the outer channel 13 is the connection part between the outer channel and the cavity 11, and the channel opening of the inner channel 12 far from the inner cavity of the body is the connection part between the inner channel and the cavity 11. Both the outer channel and the inner channel are cylindrical channels.

[0044] All the elastic air bags 14 located at the outer ends of the outer channels are interconnected through a connecting pipe 17. The connecting pipe 17 is connected to an air pump; The bottom end of the connecting pipe is communicated with the lowermost elastic airbag, and the top end of the connecting pipe is communicated with the air pump through an air pipe; after such a setting, only by starting or stopping the air pump can all the elastic airbags 14 be inflated or deflated simultaneously, so as to realize that the elastic airbag presses or does not press the elastic sheet 15. When pressing the elastic sheet, the inner channel is not communicated with the cavity channel, so that each stirring and homogenizing space in the machine body is independent and isolated from each other and not communicated. When not pressing the elastic sheet, the elastic sheet rotates outwards due to its elasticity, realizing the communication between the inner channel and the cavity channel. In this way, after the stirring and homogenizing in each stirring and homogenizing space is completed, the stirring and homogenizing spaces can be communicated, and then by opening the discharge port 10, the discharging of all the materials after the stirring and homogenizing is completed can be realized. The middle part of the elastic airbag is hermetically and fixedly connected to the inner channel opening of the outer channel, which can avoid the problem of leakage caused by the communication between the outer channel and the cavity channel. Only when the middle part of the elastic airbag is hermetically and fixedly connected (adhesive sealing can also be used) to the inner channel opening of the outer channel, the inflation and expansion and deflation and contraction of the elastic airbag can be not interfered.

[0045] Embodiment 2: The difference from Embodiment 1 is that, as Figures 6 to 10 shown, a linkage structure is arranged in the machine body 1 to realize that when the stirring shaft rotates, each stirring and homogenizing space is not communicated with each other, and when the stirring shaft stops stirring, each stirring and homogenizing space is communicated with each other; the stirring shaft 8 passes through the bottom of the machine body 1 and extends beyond the machine body. The linkage structure includes an opening 18 provided at the bottom end of the stirring shaft, and a rubber part is inserted in a matching manner with the opening; a gate valve 19 is arranged on the connecting pipe 17, a connecting rod is fixedly connected to the air pump 20, the connecting rod 21 is fixedly connected to a rotating rod, the rotating rod is connected to a sleeve 23 through a torsion spring 22, and the sleeve is fixedly connected to the handwheel of the gate valve 19; a rope 24 is wound around the surface of the sleeve, one end of the rope is fixedly connected to the surface of the sleeve 23, and the other end is wound around the rubber part and then fixedly connected to the rubber part; the rubber part is composed of a cylindrical rubber rod 25 and a pair of symmetrically arranged squares 26 fixedly connected to one end of the rubber rod, and the central connection line of the two squares passes through the diameter of the rubber rod.

[0046] The stirring shaft is rotationally and sealingly connected to the machine body; the discharge port 10 is avoided directly below the stirring shaft, that is, there is a spacing between the central position of the discharge port and the rotation axis of the stirring shaft; one end of the torsion spring 22 is fixedly connected to the rotating rod, and the other end is fixedly connected to the inner side wall of the sleeve. The rotating rod is provided at the central position of one end of the sleeve, and the inner side wall of the other end is fixedly connected to the handwheel; the square block is also made of rubber material, but the elasticity of the square block is greater than that of the rubber rod, or in other words, the hardness of the square block is less than that of the rubber rod. After such a setting, when the stirring shaft rotates, since the rubber part is inserted into the opening, similar to the connection between the shaft and the key, the rubber part also rotates. Therefore, the rope is driven to drive the sleeve to rotate. Since the sleeve is fixed to the handwheel, the handwheel rotates to open the gate valve. When the stirring shaft rotates, the gate valve is opened, and the air pump supplies air to the elastic airbag to enable the elastic sheet to seal the inner channel. After the gate valve is opened to the maximum (that is, when the handwheel cannot be rotated anymore), since the elasticity of the rubber rod is less than that of the square block, the square block deforms, forming a situation where the stirring shaft rotates relative to the rubber part, that is, the stirring shaft idles relative to the rubber part (the rubber part no longer rotates). The elasticity of the square block as such an elastic part and the friction force between the entire rubber part and the opening after the square block deforms are still sufficient to overcome the torsion of the torsion spring, but cannot overcome the rotational power of the stirring shaft (when the stirring shaft starts to rotate, the rubber part rotates with the shaft, and the square block deforms and starts to idle after being subjected to a large force); when the stirring shaft stops rotating, the sleeve resets due to the action of the torsion spring, and the rope winds reversely. At this time, since the stirring shaft no longer has a driving force, it becomes the rubber part driving the stirring shaft to rotate (at this time, the stirring shaft idles relative to the stirring motor). The reset of the sleeve closes the gate valve, and the gas in the elastic airbag is insufficient and does not press against the elastic sheet, so the inner channel is connected to the cavity channel.

[0047] To prevent the rubber part from falling out of the opening, a folding rod is provided at the bottom end of the stirring shaft. After the rubber part is inserted into the opening, its lower end abuts against the folding rod 27. The folding rod can also be set in the form of two rods hinged, and a fastening bolt is provided at the hinge. Before the rubber part is inserted, the fastening bolt is loosened, and after the rubber part is inserted into the opening, the folding rod is rotated and the fastening bolt is tightened.

[0048] When the stirring shaft rotates, each stirring and homogenizing space is independent and not connected to each other. When the stirring shaft stops stirring, each stirring and homogenizing space is connected. When the stirring shaft rotates, the cavity channel is closed. Once the stirring stops, the cavity channel is connected to the inner cavity of the machine body and is no longer closed, being in an open state. The kinetic energy of the rotation of the stirring shaft itself is utilized to realize the automatic closing and connection of the cavity channel and the machine body.

[0049] Embodiment Three: The difference from Embodiment One is that, as Figure 11 、 Figure 12As shown in the figure, the linkage structure includes a number of through holes provided on the partition plate 3. At each through hole on the partition plate 3, a rubber sleeve 28 is fixedly connected. The rubber sleeve is arranged on the upper surface of the partition plate. The inner diameter of the rubber sleeve is larger than the aperture of the through hole. The height of the rubber sleeve 28 is such that the upper end of the rubber sleeve extends beyond the lower end of the stirring blade 9 in the stirring and homogenizing space 2 where it is located. After such a setting, before adding the materials, first start the stirring motor 7 so that the stirring shaft rotates. After reaching the rotational speed, due to the rotation of the stirring shaft, the lower end of the stirring blade 9 presses the rubber sleeve 28. When the set rotational speed (the rotational speed for homogenizing stirring is relatively high) is reached, the rubber sleeve is always in a deformed and extruded state, and the through hole is closed. Each stirring and homogenizing space is independent and not connected to each other. When the stirring stops, a part of the rubber sleeve (i.e., the rubber sleeve that is not directly below the lowest end of the stirring blade) is no longer extruded, and the through hole in this part of the rubber sleeve is not closed, realizing the connection between the upper and lower stirring and homogenizing spaces. At this time, opening the discharge port can discharge all the homogenized and stirred materials; using the rotation of the stirring shaft itself to achieve the independence and non-connection of each stirring and homogenizing space 2, and when the rotation stops, each stirring and homogenizing space 2 is connected. At this time, opening the discharge port can facilitate the discharging. And the structure of this embodiment is also simple.

[0050] Embodiment 4: The difference from Embodiment 1 is that the multifunctional auxiliary agent is dandelion extract. The dandelion extract is a prior art. The preparation method is as follows: Accurately weigh 20.00 g of dandelion rhizome, add 20 times the amount of purified water and soak for 2 h. Load it into a round-bottom flask and decoct at 100 °C in an electrothermal constant temperature jacket for 50 min. Filter the filtrate with 4 layers of gauze. Add 100 mL of purified water to the filter residue and decoct at 70 °C for 30 min. Combine the filtrates and concentrate to 200 mL to obtain a dandelion extract with a crude drug content of 0.1 g / mL, which will not be elaborated.

[0051] For the case where the multifunctional auxiliary agent is dandelion extract, first dissolve and disperse water, solvent and auxiliary agent. Such as glycerol solvent, jojoba oil base oil, cetearyl alcohol, sorbitan stearate, 1,3-butanediol, purified water (or deionized water) are first stirred and homogenized for dissolution. As known from the prior art, it is heated in a water bath at 70 °C. For this process, the homogenizing emulsifier of Embodiment 1 (or Embodiments 2 and 3) can be used. The addition process of other surfactants (or multifunctional auxiliary agents) is a prior art and will not be elaborated. Water is 42.4 parts by mass. The surfactant includes 25 parts by mass of potassium cocoyl glycinate, and also includes 5 parts by mass of sodium lauroyl sarcosinate and 5 parts by mass of octyldecyl glucoside.

[0052] Example 5: The difference from Example 1 is that the multifunctional auxiliary agent is an extract of asiaticoside and ferulic acid. The extract of asiaticoside and ferulic acid is a prior art, and the preparation method is as follows: Accurately weigh 100 g of dry centella asiatica in a stew pot, add another 1200 mL of water, and boil for about 6 h; when the liquid remains about 400 mL, filter to obtain the filtrate, and place it in an oven at 60 °C to dry for 60 h to obtain a black extract. According to the material-liquid ratio of 1:20, take a certain amount of the black centella asiatica extract and acetone solution in a round-bottom flask, reflux in a water bath at 65 °C for 6 h, filter while it is hot to obtain the filter cake, and the obtained off-white substance is the crude extract of asiaticoside. Take 2 g of chuanxiong powder passed through a 120-mesh sieve in a round-bottom flask, add an ethanol solution according to the material-liquid ratio of 1:75, and reflux in a constant-temperature heating water bath at 95 °C for 35 min. Then filter, concentrate the filtrate with a rotary evaporator to 10 mL, put the extract into a centrifuge, centrifuge at 4000 r / min for 15 min to completely separate the solid and liquid, take the supernatant, and place it in a vacuum freeze dryer to dry to powder for use, which will not be elaborated.

[0053] For the case where the multifunctional auxiliary agent is an extract of asiaticoside and ferulic acid, as known from the prior art, deionized water and surfactant are dissolved and dispersed at 70 °C, and different surfactants are gradually added. Then, place it in a water bath at 40 °C and add asiaticoside, ferulic acid extract and other auxiliary agents. For the process of gradually adding different surfactants, the homogenizer of Example 1 (or Example 2 or 3) can be used. Other processes such as the addition process of the multifunctional auxiliary agent are prior arts and will not be elaborated. Water is 100 parts by mass. The extract of asiaticoside and ferulic acid is 1.5 parts by mass. The surfactant includes 1 part by mass of sodium cocoyl glycinate, and also includes ammonium lauryl sulfate, coconut glucoside, etc., which are prior arts and will not be elaborated.

[0054] Example 6: The difference from Example 1 is that the multifunctional auxiliary agent is a mixture of chitosan oligosaccharide and gelatin. The weight ratio of chitosan oligosaccharide to gelatin is 1:(1.2 - 3.1). The surfactant is sodium cocoyl glycinate, and the dosage is 1 - 5 parts by mass. The dosage of the multifunctional auxiliary agent is 2 - 5 parts by mass. Water is 5 - 15 parts by mass. For the case where the multifunctional auxiliary agent is a mixture of chitosan oligosaccharide and gelatin, it is a prior art (see the patent with the publication number CN117137817A). When stirring and homogenizing the raw materials in its component A (as well as components BCDE), the homogenizer of Example 1 (or Example 2 or 3) can be used respectively (different components use different homogenizers to ensure the required temperature), which are prior arts and will not be elaborated.

[0055] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
