The description of its functions and logic focuses on the overall design concept, operation process, and the effects and goals that can be achieved, rather than being limited to specific software and hardware implementation forms.

[0025] Example 1

[0027] Figures 3 to 6 The magnetic stirring structure connection diagram shows that the motor 1 is connected to the rotating head 2, and two permanent magnets 5 are arranged inside the rotating head 2. The stirring rod 3 is arranged in the bottle C. The stirring rod 3 is made of a permanent magnet or magnetic material, and the outer layer is made of a polytetrafluoroethylene material, or a smooth or rough coating.

[0028] The permanent magnet 5 in the rotating head 2 is set at a position corresponding to the stirring bar 3. Figure 6 As shown, if the stirring bar 3 is in the shape of a long pill, the permanent magnets 5 in the rotating head 2 are arranged so that two permanent magnets are arranged symmetrically at 180 degrees. If the stirring bar 3 is in the shape of a cross, the permanent magnets 5 in the rotating head 2 can be arranged one every 90 degrees, for a total of four. In short, the permanent magnets 5 in the rotating head 2 drive the stirring bar 3 to rotate by magnetic attraction.

[0029] Figure 7-Figure 12 Schematic diagram of the C bottle position swing mechanism. Figure 7 This is the C bottle position swing mechanism, and the front view of the C bottle outlet position; Figure 8 This is the C bottle position swing mechanism, and the top view of the C bottle outlet position; Fig. 9 This is the swing mechanism of bottle C position, and the front view of bottle C stirring position; Fig.10 It is the swing mechanism of bottle C position and the top view of bottle C stirring position; Fig.11 This is the swing mechanism of bottle C position, and the front view of bottle C titration position; Fig.12 This is the C bottle position swing mechanism, and the top view of the C bottle titration position.

[0030] The C bottle 4 can be a container such as a bottle or a can. The bottle shown in the figure is a bottle, called C bottle, which means a bottle containing raw material C. The raw material C rotating motor 7 is a mechanism that provides power, and can also be a motor or a mechanical arm. The C bottle controls the cockpit 6 by swinging the steering gear 7 to fix or release the C bottle. The cockpit 6 is controlled by swinging the steering gear 7 to swing the C bottle to the outlet position of the C bottle, or the stirring position of the C bottle, or the titration position of the C bottle.

[0031] After the stirring is completed, the cockpit 6 is controlled by swinging the servo 7 to swing the bottle C to the outlet position of the bottle C. The cockpit 6 on the robot arm hits the limit stop 10, and the clamp of the cockpit 6 is opened by squeezing, so that the bottle C is in a state where it can be taken out.

[0032] The C bottle vacancy detection sensor 9 detects whether the C bottle exists, and the swing position sensor 8 detects the position of the C bottle, thereby realizing the automatic control of the stirring of the C bottle. The principle of the sensor is not limited, and it can be realized by using the sensor of the prior art. After the C bottle is injected with the solution obtained from the previous step, the C bottle needs to be dripped with the raw material B at the titration position, then swung to the stirring position for stirring, and finally taken out at the outlet position for use.

[0033] Fig.13 , Fig.14 This is the location diagram of the titration module and the B bottle metering component. Fig.13 Figure (a) is the front view. Fig.13 Figure (b) is a top view; Fig.13 This is where bottle B is stored. Fig.14 This is a diagram of the titration position where bottle B is swung to the bottom of the titrator for raw material B. Fig.14 Figure (a) is the front view. Fig.14 Figure (b) is a top view. Bottle B represents a bottle containing raw material B.

[0034] After the initial stirring, the solution in bottle B needs to be dripped into bottle C. The titration module includes a push rod stroke sensor 19, an electric push rod 20, a motion platform 21, and a raw material B titrator 22. The electric push rod 20 drives the motion platform 21 and the raw material B titrator 22 to rise or fall, thereby absorbing the B solution from bottle B, and then dripping the B solution into bottle C. The push rod stroke sensor 19 is used to detect the stroke of the electric push rod 20, thereby realizing automatic control. The principle of the sensor is not limited, and it can be realized using sensors of the prior art.

[0035] The raw material B rotating motor 25 clamps the B bottle through a mechanical structure, and is used to control the swing position of the B bottle, and swings the B bottle to the titration position or storage position below the raw material B titrator according to the program setting. The raw material B cockpit cover motor 24 is used to open or cover the bottle cap of the B bottle. The raw material B cockpit cover motor 24 and the raw material B rotating motor 25 are a kind of motor.

[0036] The raw material B rotating motor 25 clamps the B bottle through the mechanical structure, swings the B bottle to the titration position below the raw material B titrator 22, the raw material B titrator 22 of the titration module absorbs the B solution, and then the B bottle is removed, the raw material C rotating motor 7 swings the C bottle filled with raw material A activated water and raw material C powder that has been initially stirred to the bottom of the raw material B titrator 22, and drips the B solution, after the titration is completed, the raw material C rotating motor 7 swings the C bottle to the stirring position, continues to stir, and after stirring for a predetermined time, generally 5-10 minutes, the teeth whitening gel is prepared. Each module cooperates with each other to achieve the effect of contactless and automatic stirring of liquids in a closed space.

[0037] Fig.17 The working flow diagram of the magnetic stirring device is shown in the figure. Fig.17 As shown, the workflow is as follows: 1. Stirring start command. The stirring control system issues a command, the motor is powered on, and the rotating head is driven to rotate.

[0038] 2. Magnetic stirring. The robotic arm drives bottle C to return to the specified position above the rotating head module. The magnetic stirring bar in the vial starts to rotate under the magnetic attraction of the permanent magnet in the rotating head, and drives the liquid and powder in the vial to start stirring.

[0039] 3. Stirring end command. After the magnetic stirring reaches the set time, the stirring control system issues an end command, the motor is powered off and stops working, the magnetic stirring bar stops rotating, and the mechanical arm rotates to the specified position.

[0040] When the raw material C bottle is put in, after the C bottle vacancy detection sensor 9 detects the C bottle, the system issues a command, the hatch is closed, and the raw material C rotating motor 7 drives the robot arm to move the C bottle containing the raw material C into the designated position. The C bottle vacancy detection sensor 9 can be a photoelectric sensor.

[0041] After the reactor activates the A liquid to generate activated water, the system issues a command to start the magnetic stirring unit until the gel preparation is completed. This automated design solution can complete the stirring work more efficiently.

[0042] like Fig.18 As shown, the internal structure of a tooth whitening gel preparation machine includes a raw material C rotating motor 7, a raw material B rotating motor 25, an activation reactor 27, a waste bin 28, a lifting door 29, a raw material A loading bin 30, a raw material B titrator 22, a lifting motor 32, a liquid taking valve assembly 33, a raw material A discharging motor 34, a stirring device 35, and an A bottle feeding dial 31. These components are encapsulated in a preparation machine movement assembly by metal materials such as sheet metal, lead screws, and screws.

[0043] The raw material A feeding device comprises a raw material A feeding bin 30, a raw material A discharging motor 34, an A bottle feeding dial 31, a bottle dialing shaft, and an A bottle. The container containing the raw material A is referred to as an A bottle.

[0044] The raw material A loading bin 30 is used to cache the raw material A. The raw material A is placed in the A bottle. After the raw material A is extracted, the empty A bottle will be automatically discarded to the waste bin 28 before the next preparation. The waste bin 28 is a device for collecting and storing the empty A bottles after the A liquid is extracted.

[0045] The raw material A discharging motor 34 is used to drive the loading of A bottles and the discarding of A bottles.

[0046] The A bottle feeding dial 31 is integrated on the raw material A loading bin 30 and is used for aligning the discarded bottles and the loading of the A bottles.

[0047] The raw material A feeding device includes a raw material A feeding bin 30, which is a rectangular cavity with a smooth bottom surface, used to cache containers containing raw material A, and is tilted. The feeding position is at the lowest point, and the activation reaction device is arranged at one end of the feeding position of the raw material A feeding bin. The raw material A feeding bin 30 is provided with a sheet metal base and a light shielding cover. The sheet metal base is affixed with a polytetrafluoroethylene slide to facilitate the downward sliding of the A bottle during the feeding process. The sheet metal base can also be other relatively smooth materials, not limited to polytetrafluoroethylene. The light shielding cover and the base are connected by screws, and the light shielding cover can be opened during feeding and closed after feeding. The raw material A discharging motor 34 and the A bottle feeding dial 31 and the bottle dialing shaft are connected by screws, and the raw material A discharging motor 34 drives the A bottle feeding dial 31 and the bottle dialing shaft to rotate. There are 6 evenly distributed grooves on the bottle dialing shaft, and the curvature of each groove corresponds to the curvature of the A bottle body, and the A bottle is driven to rotate by the rotation of the bottle dialing shaft. The A bottle feeding dial 31 is provided with 6 evenly distributed holes, which correspond to the 6 grooves driving the A bottle feeding dial 31 one by one, that is, the raw material A discharging motor 34 rotates the A bottle feeding dial 31 and the bottle dial shaft 60 degrees, the A bottle feeding dial 31 rotates from one hole to the position of the adjacent hole, and the bottle dial shaft rotates from the loading position corresponding to the A bottle in the groove to the loading position corresponding to the A bottle in the next groove. A dial position sensor is arranged on the upper part of the A bottle feeding dial 31, the raw material A discharging motor 34 rotates the A bottle feeding dial 31 and the bottle dial shaft, and passes through the hole of the A bottle feeding dial 31 at a fixed angle of 60 degrees, and the dial position sensor senses whether it rotates to the adjacent hole of the A bottle feeding dial 31. Once it rotates to the hole position, it is determined that it has rotated to the set position and stops rotating. The dial position sensor can be a photoelectric sensor, which relies on photoelectric sensing to determine whether it rotates to the set position of the A bottle feeding dial 31. Because the raw material A discharge motor 34 rotates the A bottle feed dial 31 and the bottle dial shaft at the same time, once the raw material A discharge motor 34 rotates to an adjacent hole position, the bottle dial shaft brings bottle A to the loading position. The material shortage detection sensor can be a photoelectric sensor or a gravity sensor. After detecting the presence of bottle A, the raw material A discharge motor 34 drives the A bottle feed dial 31 and the bottle dial shaft to rotate a fixed angle to a fixed position, and the bottle dial shaft brings bottle A to the loading position, that is, the position for extracting raw material A.

[0048] Bottles A slide down one by one to load the raw material A loading bin 30. Raw material A is sealed in a vial with a smooth bottom, i.e., bottle A, with an aluminum-plastic cap.

[0049] It also includes a motion platform, and the raw material A loading bin is set on a motion platform, and the motion platform is driven to rise and fall by a lifting motor. When sucking raw material A, the platform lifting motor drives the raw material A loading bin 30 to rise to a fixed position, and the position control is realized by controlling the angle of rotation of the motor through the communication drive of the lower computer. After the raw material A loading bin rises to a fixed position, the raw material A liquid collection needle assembly is inserted into the A bottle.

[0050] The raw material A liquid extraction needle assembly includes a curved gas needle, a straight liquid needle, a needle holder, a Luer connector, and a fixed sheet metal bracket. The bracket is set to adjust the vertical position of the entire liquid extraction module by lengthening the fixing screw hole, that is, the depth of the straight liquid needle inserted into bottle A, to ensure that the liquid in bottle A of raw material is fully discharged. The needle holder fixes the gas needle and liquid needle to the bracket through 4 screws, and the raw material A liquid extraction needle assembly is fixed on the sheet metal of the raw material A feeding device.

[0051] The position of the raw material A feeding device is at the upper end of the teeth whitening gel preparation machine, which is convenient for the raw material A to enter the activation reactor 27 after extraction. The activation reactor 27 is placed in the middle position of the teeth whitening gel preparation machine, which is also convenient for the liquid after startup to smoothly enter the C raw material bottle to prevent the occurrence of reflux of the raw material A liquid after activation.

[0052] The raw material A loading bin is arranged on a moving platform 21, and the moving platform is driven to rise and fall by a lifting motor.

[0053] Fig.18 This is a schematic diagram of the internal structure of a teeth whitening gel preparation machine. As shown in FIG18 , the lifting motor 32 is located directly below the motion platform, fixed to the movement frame by screws, and connected to the motion platform 21 by couplings and screws. The motion platform integrates components such as the raw material A loading bin 30, the raw material B titrator 22, and the raw material A discharging motor 34. Each component is fixed to the motion platform by sheet metal fixings and screws. The entire module presents an upper and lower structure. The motor controls the lifting and lowering operation of the entire lifting platform through couplings and screws. This indirectly controls the up and down movement of the raw material A loading bin 30 and the raw material B titrator 22. The working procedures of the lifting motor 32 and the raw material A loading bin 30 are set as follows: a smooth polytetrafluoroethylene patch is attached to the bottom of the raw material A loading bin. After the raw material A bottle is loaded, the raw material A bottle slides down to the groove of the bottle-push shaft by its own weight. The sensor recognizes the raw material A bottle. The program instructs the bottle-push shaft to rotate the A bottle to the loading position. The lifting motor 32 drives the screw rod to control the entire lifting platform to rise, so that the raw material A loading bin of the A bottle rises, while the raw material A liquid collection needle and gas needle assembly do not move, so that the liquid collection needle and gas needle of the raw material A liquid collection needle assembly are inserted into the A bottle. The gas needle is connected to the diaphragm pump through a hose and starts to blow air into the closed A bottle. The liquid collection needle is inserted into the bottom of the A bottle and is connected to the activation reaction device through a hose, so that the raw material A enters the activation reaction device through the liquid collection needle and the pipeline. The design of double needle insertion and pressurized extraction used to extract the raw material A liquid can ensure that the A liquid is in a fully enclosed environment before extraction. During the extraction process, the pressurized gas is filtered to ensure the cleanliness of the gas source. The bottle does not need to be inverted to extract all the solution. The method of extracting raw material A is to apply gas pressure in a closed pipeline so that the solution can enter the activation reactor along the direction of the pressure pipeline.

[0054] The activation reactor 27 is on a dedicated platform on the right side of the lifting platform, and is connected to the entire movement integrated platform by sheet metal and screws. The waste bin 28 is below the raw material A discharge motor 34. When raw material A passes through the raw material A discharge motor 34, bottle A can fall into the waste bin 28 by its own weight. The waste bin 28 is manually pluggable. When the waste bin is full, the lifting door 29 is lowered, and the waste bin 28 can be taken out and the used empty bottles of raw material A can be poured out. The lifting door 29 is fixed to the outermost side of the movement assembly by sheet metal and screws, and the lifting and lowering of the lifting door 29 is controlled by the lifting door 29 motor, screw rod and slide rail. The raw material A loading bin 30, the raw material B titrator 22, the lifting motor 32, the liquid extraction valve assembly 33, and the raw material A discharge motor 34 are fixed on the motion platform by sheet metal and screws. The overall structure is up and down, and the entire platform is driven up and down by the lifting motor and screw rod. The container of raw material B, namely bottle B, is located below the motion platform. The container containing raw material B is driven by a robotic arm to rotate to the position where the raw material B titrator extracts raw material B or to the storage position of the container containing raw material B. There is also a motor and a robotic arm, and the robotic arm is connected to a cover-removing device for the container cover of raw material B, and the cover-removing device is used to control the opening or closing of the container cover containing raw material B.

[0055] The raw material C rotating motor 7 makes bottle C swing on a horizontal plane. Swing to the stirring position, or the outlet position, or the titration position. Bottles B and C swing on the same plane, which is convenient for bottles B and C to rotate alternately to the titration position during the preparation process. Bottle B rotates to the titration position to absorb raw material B, and bottle C rotates to the titration position to drip raw material B, which is convenient for the conversion of different positions of bottles B and C during the preparation process, and realizes automatic control.

[0056] The stirring device is fixed on the movement platform by screws. After the raw material C feeding control detects that there is raw material, the upper computer confirms and closes the door, and the program will issue instructions to control the raw material C rotating motor 7 to rotate to the specified position for stirring or titration.

[0057] The integrated design and top-down layout of the above components can not only effectively reduce costs, but also promote efficient and stable operation of the equipment and reduce the failure rate. For example, the raw material A loading bin 30, the raw material B titrator 22, the lifting motor 32, and the raw material A discharge motor 34 are integrated on a lifting platform 42, and the raw material B titration and raw material A bottle puncture process can be completed with one lifting motor 32, reducing the investment of one motor and effectively reducing costs and equipment failure rates. For example, the top-down layout of the activation reactor 27, the raw material A discharge motor 34, the liquid extraction valve assembly 33, the raw material B bottle, and the raw material C bottle can not only effectively reduce the length of the hose and save costs, but also effectively reduce the liquid retention in the hose during the liquid delivery process and improve the preparation accuracy.

[0058] The activation reactor 27 is used to activate the raw material A. The activation reactor includes an activation reactor electrode driving plate unit, an activation reactor electrode, a liquid inlet and outlet unit, a gas inlet and outlet unit, and a liquid activation pool. The activation reactor electrode driving plate unit is located on the upper part of the activation reactor electrode, and the liquid activation pool is located on the lower part of the activation reactor electrode. The liquid activation pool and the activation reactor electrode form a closed cavity. It also includes a cooling fan, an activation reactor shell, and a protective coil.

[0059] The liquid activation pool material is made of polytetrafluoroethylene, and the air inlet, exhaust port, drain port, and liquid inlet are pagoda heads made of food-grade PP material, which are fastened to the liquid activation pool by threads. The activation reactor electrode drive plate unit includes the activation reactor electrode drive plate, and the activation reactor electrode drive plate, the activation reactor electrode, and the liquid activation pool are fastened together by screws. The activation reactor shell covers the activation reactor electrode drive unit, the activation reactor electrode, and the liquid activation pool. There is a cooling fan on one side of the activation reactor shell, and cooling holes are provided on the device shell opposite to the fan and on the other two sides. The fan works continuously during the working process of the activation reactor to ensure sufficient heat dissipation during the working process of the activation reactor.

[0060] The drain port 9 is placed at the bottom to fully drain the liquid without any residual liquid.

[0061] Working principle and process: When adding liquid, the raw material A liquid enters from the liquid inlet, the air inlet and the liquid discharge port are closed, and the exhaust port is opened, so that the liquid can enter the inverted pyramid-shaped liquid activation pool at the bottom. Then the activation reactor electrode drive plate unit drives the activation reactor electrode drive plate to discharge with high voltage for activation. After the activation is completed, open the air inlet and the liquid discharge port, and close the exhaust port and the liquid inlet. The air pump is connected to the air inlet through a silicone tube, blows air into the inverted pyramid-shaped liquid activation pool, and discharges the liquid out through the liquid discharge port. The raw material A solution is activated in the activation reactor and then injected into bottle C. The injection time is set to 30 seconds. During the injection of the activated A solution, the stirring device 35 is instructed to work at the same time, and the raw material B rotating motor 25 drives the raw material B cabin to reset. After the activated A solution is injected into bottle C, the raw material C rotating motor 7 is instructed to rotate to the titration position, and the lifting motor drives the screw rod 35 to control the motion platform 21 to fall above bottle C and stop. At this time, the raw material B titrator 22 is facing the bottle mouth of bottle C, and the program instructs the lifting motor to press down the push rod of the raw material B titrator 22 to drop the B solution into bottle C.

[0062] The raw material B titration device includes a push rod stroke sensor, an electric push rod, a motion platform, and a raw material B titrator 22. The electric push rod drives the motion platform to make the titrator push rod rise or fall, so as to absorb the B solution from the B bottle and then drip the B solution into the C bottle. The push rod stroke sensor is used to detect the stroke of the electric push rod to achieve automatic control. The principle of the sensor is not limited, and it can be achieved using sensors of the prior art. The raw material B titrator 22 is used to accurately set the volume of the titrated B raw material. The raw material B titrator 22 can be set with a separate motion platform to achieve lifting, or it can share a motion platform with the raw material A upper bin 30.

[0063] The raw material B feeding device includes a raw material B rotating motor 9, a raw material B filling button, a mechanical arm cockpit and a B bottle, which is a container containing raw material B. The raw material B rotating motor 25 clamps the B bottle through the mechanical arm cockpit, and the raw material B rotating motor 25 is used to control the swing position of the B bottle, and swings the B bottle to the titration position below the titrator or the B bottle storage position according to the program setting. It also includes a motor, that is, the raw material B cockpit cover motor, and a mechanical arm, which is connected to the container cover of the raw material B, and the container cover containing the raw material B is opened or closed by controlling the mechanical arm to lift or descend.

[0064] The raw material B rotating motor 25 and the cockpit cover motor are industrial standard servos, fixed to the movement frame by sheet metal, and the two motors are fixed by sheet metal and screws to cooperate with the loading raw material B program. The complete workflow of loading raw material B is: click the loading B button, the lifting motor 32 starts to rise to the preset position, the raw material B cockpit cover motor controls the mechanical arm to lift the bottle cap of bottle B, the raw material B rotating motor 25 rotates 90° clockwise to the titration position, at this time, put the raw material B bottle into the mechanical arm cockpit of the raw material B rotating motor 25, click the raw material B loading switch again, the raw material B rotating motor 25 rotates 90° counterclockwise to the B bottle storage position, and the lifting motor 32 descends to the preset position, and the B loading is completed.

[0065] The raw material B rotating motor 25 clamps the B bottle through the robot cockpit, removes the cap of the B bottle, swings the B bottle to the titration position below the raw material B titrator 22, the raw material B titrator 22 absorbs the B solution, and then moves the B bottle back to the storage position and covers the bottle cap. The raw material C rotating motor 7 swings the C bottle containing activated water and C powder that has been initially stirred to the titration position below the raw material B titrator 22, drips the B solution, and after the titration is completed, the raw material C rotating motor 7 swings the C bottle to the stirring position, and then starts stirring. After stirring for a predetermined time, generally 5-10 minutes, the teeth whitening gel is prepared. The various parts of the device cooperate with each other to achieve the effect of contactless and automatic stirring of the liquid in a closed space.

[0066] Example 2

[0067] Figure 15-16 This is another magnetic stirring structure. This structure can drive the stirrer not only to rotate, but also to vibrate up and down. The electric push rod 12 and the motor 1 are fastened to the fixed frame 11 by screws. The motor 1 drives the gear 15 through the gear 14, and the gear 15 is connected to the rotating arm 26 through the double-row ball bearing 18. A permanent magnet 5 is attached to the lower end of the rotating arm 26, and the rotating arm 25 rotates to attract the stirrer 3 to stir the raw materials in the bottle. At the same time, the electric push rod 12 moves up and down to drive the rotating arm 26 to rise and fall. The lifting of the rotating arm is fixed to the fixed frame 11 through the slider 16. The nylon protective cover 13 is used to protect the safety of the bottle.

[0068] The structure coordinated with the above two stirring embodiments also includes a raw material A feeding device, an activation reaction device, and a raw material B titration device. The raw material A is fed into the activation reaction device for activation through the raw material A feeding device, and then enters the stirring device after activation. Before the secondary stirring, the raw material B is dripped into the raw material B through the raw material B titration device, and then fully stirred to automatically prepare the teeth whitening gel.

[0069] Raw material A, raw material B, and raw material C represent one raw material or a mixture of several raw materials respectively.

[0070] Raw material A is a hydrogen peroxide solution with a concentration of 2.5%-6%, and the best effect is 6%. It is canned in a vial sealed with a rubber stopper, that is, bottle A, and the volume of bottle A is 5ml. Raw material B is a neutralizer, the main component of which is a 10% sodium hydroxide solution. It is canned in a vial sealed with a rubber stopper, that is, bottle B, and the volume of bottle B is 8ml. Raw material C is carbomer, with a mass of 0.02-0.08g, and the best single preparation is 0.04g. Raw material C and a stirrer are placed in a vial, and bottle C is a vial. In the tooth whitening gel preparation machine of this patent, the distance repeatability of the lifting platform driven by the motor is good. Bottle A will have a fixed liquid residue. In a single preparation process, 3ml of raw material A is used, about 0.2ml of A liquid remains, about 0.2ml of raw material B, and 0.04g of raw material C. It takes 5-10min activation time, 7 or 8min is optimal, when the performance of activated water reaches a stable state. The volume ratio of hydrogen peroxide solution to neutralizer is 15:1. This ratio has just the right consistency to stick to teeth and has a moderate pH. The stirring time is generally 5-10 minutes.

[0071] Ratio 1: 3.2 ml of 2.5% hydrogen peroxide solution, 0.2 ml of a neutralizer whose main component is 10% sodium hydroxide solution, and 0.02 g of carbomer.

[0072] Ratio 2: 3.2 ml of 3% hydrogen peroxide solution, 0.2 ml of a neutralizer whose main component is 10% sodium hydroxide solution, and 0.04 g of carbomer.

[0073] Ratio 3: 3.2 ml of 6% hydrogen peroxide solution, 0.2 ml of a neutralizer whose main component is 10% sodium hydroxide solution, and 0.08 g of carbomer.

[0074] The tooth whitening gels prepared by the tooth whitening gel preparation machine of the present application with the above three ratios can be directly applied to the tooth surface, and the effects are not much different. Ratio 3 has the best effect, does not require gum protectants, has a clear tooth whitening effect, and can greatly reduce the risk of common allergies caused by high-concentration hydrogen peroxide gel and soreness after whitening.

[0075] Clinical results show that the whitening gel and whitening liquid prepared using the device of the present application are non-toxic, non-irritating, and odorless, and no residual gel is left after rinsing after whitening, and have a good teeth whitening effect.

[0076] The teeth whitening effect can be adjusted by adjusting the concentration of the hydrogen peroxide solution in the raw material A, the activation time of the activation reactor, the thickness of the gel coating on the teeth, and the time the gel acts on the teeth for whitening.

[0077] The 40 subjects who participated in the clinical trial had yellow teeth with common exogenous staining. They were divided into 2 groups for testing, with 20 people in each group. The experimental group used the teeth whitening gel prepared by formula 2 and the device. The control group used 3ml ultrapure water instead of activated raw material A, the neutralizer was 0.2ml of 10% sodium hydroxide solution, and 0.04g of carbomer, and the gel was prepared manually.

[0078] The whitening method is to apply the gel to the tooth surface three times for each person, each whitening time is 15 minutes, and the cold light lamp is used for catalytic stimulation during the process, and the total action time is 45 minutes. All subjects did not use gum protectants before whitening, and did not use desensitizers after whitening.

[0079] The whitening effect is mainly judged and analyzed using the VITA Bleachedguide 3D-Master colorimetric plate, which is an intuitive visual effect analysis method commonly used in clinical practice.

[0080] The color chart (Vita chart is used as an example here) determines the color of teeth by three values: brightness, color saturation, and color value. The M column is the middle color, the L column is yellowish, and the R column is reddish. First, compare the brightness horizontally. Find the group with the highest brightness from dark to light in the 5 groups of 12345. Second, compare the saturation vertically and find the one with the best saturation. Compare the color value horizontally.

[0081] The teeth whitening gel prepared by this device has excellent whitening effect. The difference in tooth color before and after whitening, ΔE, can be 3 to 8 shades, and all participating subjects did not feel any pain after the operation.

[0082] The control group followed the same gel application and colorimetry method, and the difference in tooth color before and after whitening, ΔE, increased to nearly 0 color level.

[0083] Statistical analysis software was used to perform statistical analysis on the experimental results. The results were expressed as mean ± standard deviation, and a normal distribution test was performed. The independent sample t test or rank sum test was used for comparison between the sample group and the control group. The above statistical analyses were all two-tailed tests, with a significance level of α=0.05. The difference in tooth color before and after whitening in the sample group was ΔE=3.90±1.14. The difference in tooth color before and after whitening in the control group was ΔE=0.00±0.00. The color of the sample group after using the product was significantly different from that of the control group (P<0.01), indicating that the effect of the tooth whitening gel prepared by this mixing equipment was significantly different from that of the control group.

[0084] The gel prepared by this patented device can be used in dental clinics, oral hospitals, medical beauty institutions and other scenarios to assist doctors in cold light bleaching of yellow teeth, sensitive teeth, tea-stained teeth, smoke-stained teeth, endogenous fluorosis, and tetracycline teeth, so as to decompose the pigment groups on the surface of teeth and restore the original color of teeth. It can also be used to kill various bacteria and viruses on the surface of the skin or oral mucosa, such as treating acne, gingivitis and other inflammatory infections.
