Description

Technical Field

[0001] The present invention relates to the technical field of skin care water mixing, in particular to a mixing process and equipment for producing temperature-controlled skin care water. Background Art

[0002] Skin care water is one of the commonly used cosmetics with a wide sales volume. It is generally used for application on the human epidermis, so the production quality requirements of skin care water are relatively high.

[0003] The production process of skin lotion involves multiple temperature adjustments. The solvent must first be heated, then cooled to a certain temperature. Once cooled to the desired temperature, the remaining ingredients are added. After a certain mixing process, the product's quality is assessed through aroma and pH testing. However, these multiple temperature adjustments during the production process consume a significant amount of energy, which is not in line with energy conservation and environmental protection.

[0004] Currently, existing heat recovery equipment generally requires a dedicated drive source. This, combined with the drive source used during the skincare water mixing process, results in multiple drive sources, which can lead to energy waste. Furthermore, because the incoming water temperature fluctuates significantly during the heat recovery process, heat exchange efficiency is low when the temperature difference with the water to be cooled is small. Using a fixed heat exchange time also impacts production efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide a mixing process and equipment for producing temperature-controlled skin care water to solve the problems raised in the prior art.

[0006] To achieve the above object, the present invention provides the following technical solutions: A temperature-controlled mixing device for producing skin care water, the mixing device includes a shell, a driving device, a temperature control device and a heating tube, the driving device is placed in the shell, the temperature control device and the driving device are connected, the heating tube and the driving device are tightly connected, a working chamber is provided on the shell, the driving device includes a mixing bucket, the mixing bucket is placed in the working chamber, the mixing bucket and the working chamber are rotatably connected, an insulation layer is provided on the outside of the mixing bucket, and the temperature control device is used to control the heat exchange time.

[0007] The shell serves as the main installation base, and is used to install and fix other devices. The working chamber provides a working space. The driving device serves as the main power source, and is used to stir the raw materials of the skin care water. The heat exchange time is controlled by the temperature control device. When the stirring speed is constant, the heat exchange length can be adjusted, thereby adjusting the heat exchange time. The mixing bucket provides the main mixing and stirring space, and the outside is coated with an insulation layer. The space between the outside of the mixing bucket and the wall of the working chamber is the heat recovery zone, so that when the mixing bucket rotates in the working chamber, the liquid in the heat recovery zone will not exchange heat with the liquid in the inner cavity of the mixing bucket, thereby preventing the temperature control accuracy from being affected.

[0008] Furthermore, the driving device further comprises a stirring blade and a circulation paddle, the mixing bucket is provided with a mixing chamber, a plurality of stirring blades are provided along the inner wall of the mixing chamber, and a plurality of circulation paddles are provided along the outer wall of the mixing bucket; The temperature control device includes a temperature sensing component, a compression port is provided on the circulation paddle, an insulating flow channel is provided on the stirring blade, the compression port inlet is connected to the working chamber, the compression port outlet is connected to the insulating flow channel pipeline, a temperature sensing cavity is provided on the stirring blade, the temperature sensing component is placed in the temperature sensing cavity, the upper end of the temperature sensing component is inserted into the insulating flow channel, a heat exchange channel is provided on the stirring blade, a number of drainage channels are provided between the insulating flow channel and the heat exchange channel, a switching component is provided at the drainage channel inlet, and the temperature sensing component controls the on and off of the switching component.

[0009] The mixing chamber incorporates a stirring blade to agitate the ingredients for the skincare water. The water is made from water, and the water is initially heated to 90-95°C. Stirring maintains the heating rate, the mixture is then cooled to below 40°C before the other ingredients are added and stirred. During the cooling process, the mixing hopper uses external circulating paddles to agitate the water in the heat recovery zone. This paddle also directs the water into the stirring blades, thereby cooling the water in the mixing chamber. Because the water temperature in the heat recovery zone is uneven, the liquid diverted through the compression port enters the adiabatic flow channel. A temperature sensing chamber is located at the inlet of the adiabatic flow channel, and the temperature sensor is inserted into the channel. This temperature is measured by heat exchange. To ensure efficient measurement and shorten measurement time, the heat exchange area can be increased or the flow rate can be reduced. The inner wall of the adiabatic flow channel is coated with a thermal insulation coating to prevent water entering the channel from directly exchanging heat with the stirring blades and the water in the mixing chamber, affecting the heat exchange time adjustment. By providing multiple diversion channels, the heat exchange channel can be arranged in a stepped pattern, extending the heat exchange length. Each diversion channel connects to a different stage of the heat exchange channel. The conduction state of the switching components is adjusted according to the inlet water temperature. Initially, all switching components maintain the diversion channel inlet in a truncated state. During cooling, the lower the water temperature, the more diversion channels farther away from the temperature-sensing components are open, which means the heat exchange path is longer and the heat exchange time with the water in the mixing chamber is longer, thereby increasing the cooling rate. As the mixing bucket rotates, the water in the heat exchange channel flows under the influence of centrifugal force and gravity, ultimately flowing out of the drain port.

[0010] Furthermore, the temperature sensing component includes a temperature sensing airbag and a heat exchange plate. The upper side of the temperature sensing airbag is tightly connected to the temperature sensing cavity. The lower end of the heat exchange plate is inserted into the temperature sensing airbag, and the upper end of the heat exchange plate is inserted into the insulation flow channel. A bottom plate is provided at the lower end of the temperature sensing airbag, and the bottom plate and the temperature sensing cavity are slidingly connected. A top rod is provided at the lower end of the bottom plate, and a coil is provided in the temperature sensing cavity. The lower end of the top rod is inserted into the coil, and the top rod is made of magnet material.

[0011] The upper end of the heat exchanger is inserted into the adiabatic flow channel to sense temperature. The higher the temperature, the greater the expansion of the temperature-sensing airbag, pushing the base plate farther. The push rod moves within the inner coil, causing the coil to cut through the magnetic flux lines, generating more current. The corresponding current signal is collected and divided into intervals, with each current interval corresponding to a group of switching components. When the current signal is low, the inlet water temperature is low, and the switching components in the drainage channel away from the adiabatic flow channel inlet are turned on, while the other groups of switching components remain in the off state. Temperature control is achieved through a single on state to ensure heat exchange efficiency.

[0012] Furthermore, a switching groove is provided on the stirring blade, and the switching assembly includes an electromagnet, a switching plate and a reset spring. The electromagnet is placed in the switching groove, and the switching plate is rotatably connected to the drainage channel. The switching plate is made of a magnet material.

[0013] A switching slot is set at the inlet of the drainage channel to adjust the conduction state of the drainage channel. According to the current signal divided into intervals on the coil, power is supplied to the electromagnet respectively. The electromagnet adopts dual power supply. The current signal on the coil is the control current for the electromagnet to control the opening of the switching plate. After the diversion is completed, as the temperature fluctuates, a reverse current is input to the electromagnet at the open position. Under the action of the magnetic pole attraction, the switching plate here is controlled to rotate toward the electromagnet, thereby closing the drainage channel, which is convenient for automatic switching according to water bodies of different temperatures.

[0014] Furthermore, the switching assembly also includes a return spring, one end of the return spring is fastened to the switching plate, and the other end is fastened to the drainage channel.

[0015] By setting a reset spring and fixing both ends to connect the switching plate and the drainage channel respectively, when the drainage channel is opened, the reset spring is in a stretched state. When it needs to be closed, the elastic force of the reset spring assists in automatic closing, thereby improving the rapid response rate.

[0016] Furthermore, a liquid discharge port is provided on the circulation paddle, and the liquid discharge port is connected to the heat exchange channel pipeline.

[0017] By setting a drain port and connecting it to the heat exchange channel, the heated water is discharged into the working chamber to mix the remaining water in the working chamber, thereby improving the heat recovery efficiency.

[0018] Furthermore, the compression port is located at the upper end of the discharge port, the cross section of the circulation paddle is arc-shaped, the compression port is located on the concave surface inside the circulation paddle, and the discharge port is located on the convex surface outside the circulation paddle.

[0019] By setting a height difference between the compression port and the discharge port, when the circulation paddle rotates, the water is pressed into the compression port. As a result, during the rotation of the mixing bucket, the stirring blades and the circulation paddle can be driven to stir the inside and outside. At the same time, the rotation can press the water into the compression port for forced circulation, thereby reducing energy consumption.

[0020] Furthermore, the driving device also includes a power motor, a driving cavity is provided on the shell, the power motor is placed in the driving cavity, a driving gear is provided at the output end of the power motor, an external tooth surface is provided on the mixing bucket, and the power motor is engaged with the external tooth surface through the driving gear.

[0021] The power motor is used to output torque, and drives the mixing bucket to rotate by engaging the driving gear with the outer tooth surface, so that only one power source is needed to meet the stirring effect of the inner and outer layers at the same time.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: the conduction state of the switching component is adjusted according to the different inlet water temperatures. In the initial state, all switching components keep the drainage channel inlet in the cut-off state; when cooling, the lower the water temperature, the more the drainage channel away from the temperature-sensing component is conductive, that is, the longer the heat exchange circulation stroke, and the longer the heat exchange time with the water in the mixing chamber, thereby improving the cooling rate; the higher the temperature, the greater the expansion degree of the temperature-sensing airbag, the longer the distance the bottom plate is pushed to move, and the push rod moves in the inner circle of the coil, so that more current is generated by the coil cutting the magnetic flux lines, and the corresponding current signal is collected and divided into intervals, and each current interval corresponds to a group of switching components. When the current signal is small, the inlet water temperature is low, and the switching component of the drainage channel away from the inlet of the adiabatic flow channel is turned on, while the switching components of other groups are still in the off state. The temperature is controlled by a single on state to ensure the heat exchange efficiency. According to the current signal divided into intervals on the coil, the electromagnets are powered separately. The electromagnets are powered by dual power supplies, and the current signal on the coil is the control current for the electromagnet to control the opening of the switching plate. After the diversion is completed, as the temperature fluctuates, a reverse current is input to the electromagnet at the open position. Under the action of the magnetic pole attraction, the switching plate here is controlled to rotate toward the electromagnet, thereby closing the drainage channel, which is convenient for automatic switching according to water bodies of different temperatures. During the rotation of the mixing bucket, it can drive the stirring blades and circulation paddles to stir inside and outside, and at the same time, the rotation can press the water into the compression port for forced circulation, reducing energy consumption.

[0025] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0026] Example: Figures 1-6 As shown, the present invention provides a mixing process and equipment technical solution for the production of temperature-controlled skin care water.

[0028] The shell 1 serves as the main installation base for installing and fixing other devices, and provides a working space through the working chamber 11. The driving device 2 serves as the main power source for stirring the raw materials of the skin care water. The heat exchange time is controlled by the temperature control device 3. When the stirring speed is constant, the heat exchange length can be adjusted to adjust the heat exchange time. The mixing bucket 22 provides the main mixing and stirring space, and the outside is coated with an insulation layer. The space between the outside of the mixing bucket 22 and the wall of the working chamber 11 is the heat recovery zone, so that when the mixing bucket 22 rotates in the working chamber 11, the liquid in the heat recovery zone will not exchange heat with the liquid in the inner cavity of the mixing bucket 22, so as to prevent affecting the temperature control accuracy.

[0029] Furthermore, the driving device 2 further includes a stirring blade 23 and a circulation paddle 24. The mixing hopper 22 is provided with a mixing chamber 221. A plurality of stirring blades 23 are provided along the inner wall of the mixing chamber 221. A plurality of circulation paddles 24 are provided along the outer wall of the mixing hopper 22. The temperature control device 3 includes a temperature sensing component 31, a compression port 241 is provided on the circulation paddle 24, an insulating flow channel 232 is provided on the stirring blade 23, the inlet of the compression port 241 is connected to the working chamber 11, and the outlet of the compression port 241 is connected to the insulating flow channel 232 pipeline. A temperature sensing cavity 231 is provided on the stirring blade 23, and the temperature sensing component 31 is placed in the temperature sensing cavity 231. The upper end of the temperature sensing component 31 is inserted into the insulating flow channel 232. A heat exchange channel 235 is provided on the stirring blade 23, and several drainage channels 234 are provided between the insulating flow channel 232 and the heat exchange channel 235. A switching component 32 is provided at the inlet of the drainage channel 234, and the temperature sensing component 31 controls the on and off of the switching component 32.

[0030] The mixing chamber 221 has a built-in stirring blade 23 for stirring the raw materials of the skin care water. The solvent used for the raw materials of the skin care water is water. When processing, it needs to be heated to 90-95°C first, and the heating rate is maintained by stirring. After the heating is completed, it is cooled to below 40°C, and other raw materials are added for stirring. During the cooling process, the mixing bucket 22 stirs the water in the heat recovery area through the outer circulation paddle 24, and guides the water into the stirring blade 23 through the circulation paddle 24, thereby cooling the water in the mixing chamber 221. Since the temperature of the water in the heat recovery area is uneven, the liquid guided through the compression port 241 enters the adiabatic flow channel 232. A temperature sensing chamber 231 is set at the inlet of the adiabatic flow channel 232. The temperature sensing end is inserted into the adiabatic flow channel 232. The temperature of the inlet liquid is measured by heat exchange. In order to ensure the efficiency of temperature measurement and shorten the temperature measurement time, the heat exchange area can be increased or the flow rate can be reduced. The inner wall of the adiabatic flow channel 232 is coated with a thermal insulation coating to prevent water from directly exchanging heat with the water in the mixing chamber 221 through the stirring blades 23 after entering the adiabatic flow channel 232, thereby affecting the regulation of the heat exchange time. By providing multiple diversion channels 234, the heat exchange channel 235 can be arranged in a stepped manner, extending the heat exchange length. Each diversion channel 234 connects to a different stage of the heat exchange channel 235. The conduction state of the switching assembly 32 is adjusted according to the inlet water temperature. Initially, all switching assemblies 32 maintain the inlet of the diversion channel 234 in a truncated state. During cooling, the lower the water temperature, the more diversion channels 234 farther away from the temperature sensing assembly 31 are open, that is, the longer the heat exchange flow path and the longer the heat exchange time of the water in the mixing chamber 221, thereby increasing the cooling rate. During the rotation of the mixing hopper 22, the water in the heat exchange channel 235 flows under the influence of centrifugal force and gravity, and ultimately flows out through the drain port 242.

[0031] Furthermore, the temperature sensing component 31 includes a temperature sensing airbag 311 and a heat exchange plate 312. The upper side of the temperature sensing airbag 311 is fastened to the temperature sensing cavity 231. The lower end of the heat exchange plate 312 is inserted into the temperature sensing airbag 311. The upper end of the heat exchange plate 312 is inserted into the insulation flow channel 232. A bottom plate 313 is provided at the lower end of the temperature sensing airbag 311. The bottom plate 313 and the temperature sensing cavity 231 are slidably connected. A top rod 314 is provided at the lower end of the bottom plate 313. A coil 315 is provided in the temperature sensing cavity 231. The lower end of the top rod 314 is inserted into the coil 315. The top rod 314 is made of magnet material.

[0032] The upper end of the heat exchanger fin 312 is inserted into the adiabatic flow channel 232 to sense temperature. The higher the temperature, the greater the expansion of the temperature-sensing airbag 311, pushing the base plate 313 a greater distance. The push rod 314 moves within the inner circle of the coil 315, causing the coil 315 to cut through the magnetic flux lines and generate more current. The corresponding current signal is collected and divided into intervals, with each current interval corresponding to a group of switching components 32. When the current signal is low, the inlet water temperature is low, and the switching components 32 located in the drainage channel 234 away from the inlet of the adiabatic flow channel 232 are turned on. The other groups of switching components 32 remain in the off state. Temperature control is achieved through a single on state to ensure heat exchange efficiency.

[0033] Furthermore, a switching slot 233 is provided on the stirring blade 23, and the switching assembly 32 includes an electromagnet 321, a switching plate 322 and a return spring 323. The electromagnet 321 is placed in the switching slot 233, the switching plate 322 and the drainage channel 234 are rotatably connected, and the switching plate 322 is made of magnet material.

[0034] A switching slot 233 is provided at the inlet of the drainage channel 234 for adjusting the conduction state of the drainage channel 234. Power is supplied to the electromagnet 321 according to the current signal divided into intervals on the coil 315. The electromagnet 321 adopts a dual power supply. The current signal on the coil 315 is the control current for the electromagnet 321 to control the opening of the switching plate 322. After the diversion is completed, as the temperature fluctuates, a reverse current is input to the electromagnet 321 at the open position. Under the action of the magnetic pole attraction, the switching plate 322 here is controlled to rotate toward the electromagnet 321, thereby closing the drainage channel 234, which is convenient for automatic switching according to water bodies of different temperatures.

[0035] Furthermore, the switching assembly 32 further includes a return spring 323 , one end of the return spring 323 is fastened to the switching plate 322 , and the other end is fastened to the drainage channel 234 .

[0036] By setting a return spring 323 and fixing both ends to connect the switching plate 322 and the drainage channel 234 respectively, when the drainage channel 234 is opened, the return spring 323 is in a stretched state. When it needs to be closed, the elastic force of the return spring 323 assists in automatic closing, thereby improving the rapid response rate.

[0037] Furthermore, a drain port 242 is provided on the circulation paddle 24 , and the drain port 242 is connected to the heat exchange channel 235 .

[0038] By providing a drain port 242 and communicating with the heat exchange channel 235 , the heated water is discharged into the working chamber 11 to mix the remaining water in the working chamber 11 , thereby improving the heat recovery efficiency.

[0039] Furthermore, the compression port 241 is located at the upper end of the discharge port 242 . The cross section of the circulation paddle 24 is arc-shaped. The compression port 241 is located on the concave surface inside the circulation paddle 24 , and the discharge port 242 is located on the convex surface outside the circulation paddle 24 .

[0040] By setting a height difference between the compression port 241 and the discharge port 242, when the circulation paddle 24 rotates, the water is pressed into the compression port 241, so that during the rotation of the mixing bucket 22, the stirring blade 23 and the circulation paddle 24 can be driven to stir the inside and outside, and at the same time, the rotation can press the water into the compression port 241 for forced circulation, thereby reducing energy consumption.

[0041] Furthermore, the driving device 2 also includes a power motor 21, a driving chamber 12 is provided on the shell 1, the power motor 21 is placed in the driving chamber 12, a driving gear is provided at the output end of the power motor 21, and an external tooth surface 222 is provided on the mixing bucket 22. The power motor 21 is engaged with the external tooth surface 222 through the driving gear.

[0042] The power motor 21 is used to output torque, and drives the mixing bucket 22 to rotate by engaging the driving gear and the outer tooth surface 222, so that only one power source is required to meet the mixing effect of the inner and outer layers at the same time.

[0043] The mixing process includes the following steps: Step 1: First, add a solvent into the mixing chamber 221, wherein the solvent is water.

[0044] Step 2: Heat the water in the mixing chamber 221 to 90.0-95.0°C through the heating tube 4. During the heating process, the inner wall of the working chamber 11 and the mixing bucket 22 remain in a liquid-free state, the external resistance is minimal, the heating efficiency in the mixing chamber 221 is highest, the stirring speed is 15-35rpm, and the stirring time is 30-45min.

[0045] Step 3: Water is introduced between the working chamber 11 and the mixing hopper 22. The mixing hopper 22 is driven to rotate by the power motor 21, so that during rotation, the compression port 241 of the circulating paddle 24 rotates toward the water and presses some of the water into the adiabatic flow channel 232 through the compression port 241. By detecting the temperature of the water at the inlet of the adiabatic flow channel 232 and opening the corresponding diversion channel 234, one group of switching components 32 is controlled to be turned on at a time, while the other groups are closed. This adjusts the heat exchange stroke length and heat exchange time according to the inlet water temperature, thereby improving heat exchange efficiency. When the temperature cools to below 40°C, the remaining raw materials, such as moisturizers, antioxidants, and skin conditioners, are added. The stirring speed is controlled to 15-35 rpm and the stirring time is controlled to 15-20 minutes.

[0046] Step 4: Preliminary inspection of appearance, aroma and pH value before discharging. After passing the inspection, the semi-finished product is discharged. The discharge port can be located at the lower end of the mixing bucket 22, and pass through the working cavity of the shell 1 and be drained through the pipeline.

[0047] As an optimization, the mixing chamber 221 of the mixing bucket 22 can be directly inserted from above the shell 1 by pump suction to directly pump liquid, thereby reducing the difficulty of overall sealing.

[0048] The working principle of the present invention is as follows: the conduction state of the switching component 32 is adjusted according to the different inlet water temperatures. In the initial state, all the switching components 32 keep the inlet of the drainage channel 234 in a cut-off state; when cooling, the lower the water temperature, the more the drainage channel 234 away from the temperature sensing component 31 is conductive, that is, the longer the heat exchange circulation stroke is, and the longer the heat exchange time with the water in the mixing chamber 221 is, the cooling rate is improved; the higher the temperature, the greater the expansion degree of the temperature sensing airbag 311, the longer the distance the bottom plate 313 is pushed to move, and the push rod 314 moves in the inner circle of the coil 315, so that the coil 315 generates more current by cutting the magnetic flux lines, and the corresponding current signal is collected and divided into intervals. Each current interval corresponds to a group of switching components 32. When the current signal is small, the inlet water temperature is low, and the switching component 32 where the drainage channel 234 away from the inlet of the adiabatic flow channel 232 is located is turned on, and the switching components 32 of other groups are still in the off state. The temperature is controlled by the single conduction state to ensure the heat exchange efficiency; according to the current signal divided by the interval on the coil 315, the electromagnet 321 is powered respectively. The electromagnet 321 adopts dual power supply. The current signal on the coil 315 is the control current for the electromagnet 321 to control the opening of the switching plate 322; after the diversion is completed, as the temperature fluctuates, the reverse current is input to the electromagnet 321 at the open position. Under the action of the magnetic pole attraction, the switching plate 322 here is controlled to rotate toward the electromagnet 321, so that the drainage channel 234 is closed, which is convenient for automatic switching according to water bodies of different temperatures; during the rotation of the mixing bucket 22, it can drive the stirring blade 23 and the circulation paddle 24 to stir inside and outside, and at the same time, the rotation can press the water into the compression port 241 for forced circulation, thereby reducing energy consumption.
