[0003] The technical drawbacks of the existing solutions are as follows: With this stirring method, it is relatively difficult to clean the stirring rod, extremely inconvenient to use, and prone to contaminating the tooth whitening gel, making it difficult to ensure a good hygienic environment. Summary of the Invention

[0004] The main purpose of this application is to overcome the above-mentioned defects of the existing technology, and provides a tooth whitening gel preparation machine, which includes a bottle C for containing raw material C, a stirrer, and a power drive module. The stirrer is arranged inside the bottle C, and the stirrer is made of a magnetic or ferromagnetic material that attracts magnetic materials; the power drive module drives the structure that magnetically attracts the stirrer to rotate, so as to drive the stirrer to rotate inside the bottle C with magnetic attraction force to stir the raw materials in the bottle; it also includes a raw material B rotating motor, which drives the bottle B containing raw material B to rotate to the position where the raw material B titrator extracts raw material B through a robotic arm; the position where the raw material B titrator extracts raw material B and the C bottle titration position where raw material B is dropped into the bottle C before secondary stirring are the same position, and the bottle B and the bottle C rotate on the same plane. This layout of the positional relationship is conducive to the automated preparation of tooth whitening gel.

[0013] Preferably, it further includes a limit stop block. After the stirring is completed, the raw material C rotating motor swings the cockpit through the robotic arm, thereby driving the C bottle to rotate to the outlet position. When the cockpit hits the limit stop block, the clamping force of the cockpit on the bottle becomes smaller, making the C bottle in a relaxed and removable state, and the C bottle can be removed.

[0014] Preferably, it further includes a lifting door, which is arranged on the outermost side of the movement assembly. The inside of the C bottle is the prepared tooth whitening gel.

[0041] In the patent application documents of this application, the modules, units, mechanisms, devices, etc. involved are not limited to a specific software or hardware environment. They have a high degree of abstraction and flexibility. Whether it is a software module that realizes specific functions by running a software program or a hardware unit constructed based on physical circuits, mechanical structures, etc., they are all within the scope of writing patent application documents. The description of their functions and logics focuses on the overall design concept, operation process, and the effects and goals that can be achieved, rather than being limited to the specific software and hardware implementation forms.

[0042] Example 1

[0043] A tooth whitening gel preparation machine includes a bottle C for containing raw material C, a stirrer, and a power drive module. The stirrer is arranged in bottle C. The stirrer is made of magnetic or ferromagnetic material that attracts magnetic material. The power drive module drives the structure that magnetically attracts the stirrer to rotate, thereby driving the stirrer to rotate in bottle C by magnetic attraction to stir the raw materials in the bottle. It also includes a rotating motor for raw material B, which drives the bottle B containing raw material B to rotate to the position where the raw material B titrator extracts raw material B through a robotic arm. The position where the raw material B titrator extracts raw material B and the titration position of bottle C where raw material B is dropped into bottle C before secondary stirring are the same position. Bottle B and bottle C rotate on a plane. This layout of the positional relationship is conducive to the automated preparation of tooth whitening gel. It also includes a program control system that automatically prepares tooth whitening gel according to the set program.

[0044] Figures 3 to 6 It is a connection diagram of the magnetic stirring structure. The motor 1 is connected to the rotating head 2, and two permanent magnets 5 are arranged inside the rotating head 2. The stirrer 3 is arranged in bottle C. Inside the stirrer 3 is a permanent magnet or magnetic material, and the outer layer is wrapped with polytetrafluoroethylene material, either smooth or with a rough coating.

[0045] The positions of the permanent magnets 5 in the rotating head 2 correspond to those of the stirrer 3. As Figure 6 shown, if the shape of the stirrer 3 is a long pill shape, the permanent magnets 5 in the rotating head 2 are arranged symmetrically at 180 degrees. If the stirrer 3 is cross-shaped, one permanent magnet 5 can be arranged every 90 degrees in the rotating head 2, with a total of 4 arranged. In short, the permanent magnets 5 in the rotating head 2 drive the stirrer 3 to rotate by magnetic attraction.

[0046] Figures 7 - 12 It is a schematic diagram of the swing mechanism for the position of bottle C. Figure 7 It is the front view of the swing mechanism for the position of bottle C at the outlet of bottle C; Figure 8 It is the top view of the swing mechanism for the position of bottle C at the outlet of bottle C; Figure 9 It is the front view of the swing mechanism for the position of bottle C at the stirring position; Figure 10 It is the top view of the swing mechanism for the position of bottle C at the stirring position; Figure 11 It is the front view of the swing mechanism for the position of bottle C at the titration position; Figure 12 It is the top view of the swing mechanism for the position of bottle C at the titration position.

[0047] The C bottle 4 can be a container such as a bottle or a jar. In the figure, it is shown as a bottle, called the C bottle, which represents the bottle for holding raw material C. The raw material C rotating motor 7 is a mechanism that provides power and can also be a motor or a robotic arm. The C bottle controls the cockpit 6 through the swing servo 7 to fix or release the C bottle. The cockpit 6 is controlled by the swing servo 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.

[0048] After the stirring is completed, the cockpit 6 is controlled by the swing servo 7 to swing the C bottle to the outlet position of the C bottle. The cockpit 6 on the robotic arm hits the limit stop 10, and the extrusion will open the clip of the cockpit 6, making the C bottle in a state where it can be taken out.

[0049] The presence of the C bottle is detected by the C bottle vacancy detection sensor 9, and the position of the C bottle is detected by the swing position sensor 8, so as to realize the automatic control of the stirring of the C bottle. The principle of the sensor is not limited, and the sensors of the existing technology can be used to achieve it. After the C bottle is injected with the solution obtained from the previous step, the C bottle needs to drop the raw material B at the titration position, then swing to the stirring position for stirring, and finally be taken out and used at the outlet position.

[0050] Figure 13 、 Figure 14 It is a position diagram of the titration module and the B bottle metering component. Figure 13 Figure (a) in it is the front view. Figure 13 Figure (b) in it is the top view. Figure 13 It is the storage position of the B bottle. Figure 14 It is a diagram of the B bottle swinging to the titration position below the raw material B titrator. Figure 14 Figure (a) in it is the front view. Figure 14 Figure (b) in it is the top view. The B bottle represents the bottle for holding raw material B.

[0051] After the preliminary stirring, the solution in the B bottle needs to be dropped into the C bottle. The titration module includes a push rod stroke sensor 19, an electric push rod 20, a moving platform 21, and a raw material B titrator 22. The electric push rod 20 drives the moving platform 21 and the raw material B titrator 22 to rise or fall, so as to suck the B solution from the B bottle and then drop the B solution into the C bottle. The push rod stroke sensor 19 is used to detect the stroke of the electric push rod 20, so as to realize automatic control. The principle of the sensor is not limited, and the sensors of the existing technology can be used to achieve it.

[0052] The raw material B rotating motor 25 holds the B bottle through a mechanical structure and is used to control the swing position of the B bottle. According to the program setting, the B bottle is swung to the titration position and / or the storage position below the raw material B titrator. 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.

[0053] The raw material B rotating motor 25 holds the B bottle through a mechanical structure, swings the B bottle to the titration position below the raw material B burette 22 of the titration module. The raw material B burette 22 of the titration module sucks the B solution, then removes the B bottle. The raw material C rotating motor 7 swings the C bottle filled with the activated water of raw material A and the powder of raw material C that has been preliminarily stirred to the position below the raw material B burette 22, drips in the B solution. After the titration is completed, the raw material C rotating motor 7 swings the C bottle to the stirring position and continues to stir. After stirring for a predetermined time, generally 5 - 10 minutes, the tooth whitening gel is prepared. Each module cooperates with each other to achieve the effect of non-contact and automated stirring of the liquid in a closed space.

[0054] Figure 17 The working flowchart of the magnetic stirring device is as shown in the figure, as Figure 17 shown, and the working process is as follows:

[0055] 1. Stirring start instruction. The stirring control system issues an instruction, the motor is powered on and works, driving the rotating head to rotate.

[0056] 2. Magnetic stirring. The robotic arm drives the C bottle to reset to the specified position above the rotating head module. The magnetic stirring bar in the vial starts to rotate under the magnetic suction of the permanent magnet in the rotating head, and drives the liquid and powder in the vial to start stirring.

[0057] 3. Stirring end instruction. After magnetic stirring for the set time, the stirring control system issues an end instruction, the motor is powered off and stops working, the magnetic stirring bar stops rotating, and the robotic arm rotates to the specified position.

[0058] When putting the raw material C bottle, after the C bottle vacancy detection sensor 9 detects the C bottle, the system issues an instruction, the hatch closes, and the raw material C rotating motor 7 drives the robotic arm to move the C bottle filled with raw material C to the specified position. The C bottle vacancy detection sensor 9 can be an optoelectronic sensor.

[0059] After the activation reaction kettle activates the A liquid to generate activated water, the system issues an instruction to start the magnetic stirring unit until the gel preparation is completed. This automated design scheme can complete the stirring work with higher efficiency.

[0060] As Figure 18 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 reaction kettle 27, a waste bin 28, a lifting door 29, a raw material A feeding bin 30, a raw material B burette 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 the preparation machine core assembly by metal materials such as sheet metal, lead screws, and screws.

[0061] The raw material A feeding device includes a raw material A feeding bin 30, a raw material A discharging motor 34, an A-bottle feeding dial 31, a bottle dialing rotating shaft, and A-bottles. The container filled with raw material A is simply referred to as an A-bottle.

[0062] The raw material A feeding bin 30 is used to cache raw material A. Raw material A is contained in an A-bottle. After the raw material A is extracted, the empty A-bottle will be automatically discarded into the waste bin 28 before the next preparation. The waste bin 28 is a device for collecting and storing the empty A-bottles after extracting A liquid.

[0063] The raw material A discharging motor 34 is used to drive the feeding of A-bottles and the discarding of A-bottles.

[0064] The A-bottle feeding dial 31 is integrated on the raw material A feeding bin 30 and is used for the alignment of A-bottle discarding and feeding.

[0065] The feeding device for raw material A includes a feeding bin 30 for raw material A. The feeding bin 30 for raw material A is a cuboid cavity with a smooth bottom, which is used to cache the containers filled with raw material A. It is inclined, and the feeding position is at the lowest point. The activation reaction device is arranged at one end of the feeding position of the feeding bin for raw material A. The feeding bin 30 for raw material A is provided with a sheet metal base and a light-shielding cover. The sheet metal base is pasted with a polytetrafluoroethylene sliding sheet to facilitate the downward sliding during the feeding process of bottle A. The sheet metal base can also be made of other relatively slippery materials, not limited to being pasted with polytetrafluoroethylene. The light-shielding cover and the base are connected by screws. The light-shielding cover can be opened during feeding and closed after feeding. The raw material A discharging motor 34, the A bottle feeding dial 31 and the bottle dialing rotating shaft are connected by screws. The raw material A discharging motor 34 drives the A bottle feeding dial 31 and the bottle dialing rotating shaft to rotate. There are 6 evenly distributed grooves on the bottle dialing rotating shaft, and the radian of each groove corresponds to the radian of the bottle body of bottle A. The rotation of the bottle dialing rotating shaft drives the rotation of bottle A. The A bottle feeding dial 31 is provided with 6 evenly distributed holes, which correspond one by one to the 6 grooves driving the A bottle feeding dial 31. That is, when the raw material A discharging motor 34 rotates the A bottle feeding dial 31 and the bottle dialing rotating shaft by 60 degrees, the A bottle feeding dial 31 rotates from one hole to the position of the adjacent hole, and the bottle dialing rotating shaft rotates from the position where one groove corresponds to the feeding position of bottle A to the position where the next groove corresponds to the feeding position of bottle A. 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 dialing rotating shaft. Through the holes of the A bottle feeding dial 31 at a fixed angle of 60 degrees, it is sensed by the dial position sensor whether it has rotated 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 an optoelectronic sensor, which relies on optoelectronic induction to determine whether it has rotated to the set position of the A bottle feeding dial 31. Because the raw material A discharging motor 34 rotates the A bottle feeding dial 31 and the bottle dialing rotating shaft at the same time, once the raw material A discharging motor 34 rotates to an adjacent hole position, the bottle dialing rotating shaft will bring bottle A to the feeding position. The material shortage detection sensor can be an optoelectronic sensor or a gravity sensor. After detecting that there is a bottle A, the raw material A discharging motor 34 drives the A bottle feeding dial 31 and the bottle dialing rotating shaft to rotate a fixed angle to a fixed position, and the bottle dialing rotating shaft will bring bottle A to the feeding position, that is, the position for extracting raw material A.

[0066] Bottles A slide out one by one for bottle feeding in the feeding bin 30 for raw material A. Raw material A is sealed in a vial with a smooth bottom by an aluminum-plastic cap, that is, bottle A.

[0067] It also includes a moving platform. The feeding bin for raw material A is arranged on a moving platform and is driven by a lifting motor to lift the moving platform. When sucking raw material A, the platform lifting motor drives the feeding bin 30 for raw material A to rise to a fixed position, and the position control is realized by driving and controlling the rotation angle of the motor through the communication of the lower computer. After the feeding bin for raw material A rises to the fixed position, the liquid extraction needle assembly for raw material A is inserted into bottle A.

[0068] The liquid-taking needle assembly for raw material A includes a gas needle bent needle head, a liquid needle straight needle head, 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-taking module through the lengthened fixed screw holes, that is, the depth of the liquid needle straight needle head inserted into bottle A of raw material A, so as to ensure that the liquid in bottle A of raw material A is fully discharged. The needle holder fixes the gas needle and the liquid needle on the bracket through 4 screws, and the liquid-taking needle assembly for raw material A is fixed on the sheet metal part of the raw material A feeding device.

[0069] The position of the raw material A feeding device is at the upper end of the tooth whitening gel preparation machine, which is convenient for pumping and then entering the activation reaction kettle 27 downward. The activation reaction kettle 27 is placed in the middle position of the tooth whitening gel preparation machine, which is also convenient for the liquid after startup to smoothly enter the C raw material bottle and prevent the backflow of the liquid of raw material A after activation.

[0070] The raw material A feeding bin is arranged on a moving platform 21, and the moving platform is driven by a lifting motor to move up and down.

[0071] Figure 18 It is a schematic diagram of the internal structure of a tooth whitening gel preparation machine. As shown in Figure 18, the lifting motor 32 is located directly below the moving platform, fixed to the movement mechanism frame by screws, and connected to the moving platform 21 through a coupling and a lead screw. Components such as the raw material A feeding bin 30, the raw material B titrator 22, and the raw material A discharging motor 34 are integrated on the moving platform. Each component is fixedly connected to the moving platform through sheet metal fixing parts and screws. The entire module presents an up-and-down structure, and the motor controls the lifting operation of the entire lifting platform through a coupling and a lead screw. Thereby indirectly controlling the up-and-down movement of the raw material A feeding bin 30 and the raw material B titrator 22. The working procedures of the lifting motor 32 and the raw material A feeding bin 30 are set as follows: A smooth polytetrafluoroethylene patch is pasted on the bottom of the raw material A feeding bin. After filling the raw material A bottle, the raw material A bottle slides down to the groove of the bottle-pushing rotating shaft by its own weight. The sensor recognizes the raw material A bottle, and the program commands the bottle-pushing rotating shaft to rotate the A bottle to the feeding position. The lifting motor 32 drives the lead screw to control the entire lifting platform to rise. Thus, the raw material A feeding bin of the A bottle rises, while the liquid-taking needle and the gas needle assembly of the raw material A liquid-taking needle assembly remain stationary, so that the liquid-taking needle and the gas needle of the raw material A liquid-taking needle assembly penetrate into the A bottle. The gas needle is connected to a diaphragm pump through a hose and starts to blow air into the closed A bottle. The liquid-taking needle reaches the bottom of the A bottle and is connected to the activation reaction device through a hose. Thereby, raw material A enters the activation reaction device through the liquid-taking needle and the pipeline. The design of double needles penetrating and pressurized extraction is adopted for extracting the liquid of raw material A. This design can ensure that the environment of raw material A liquid is fully sealed before extraction. During the extraction process, the pressurized gas passes through filtration to ensure the cleanliness of the gas source. The solution can be completely extracted without inverting the bottle body. The method of extracting raw material A is to apply gas pressure in a closed pipeline, so that the solution can enter the activation reaction kettle along the direction of the pressure pipeline.

[0072] The activation reactor 27 is on the exclusive platform on the right side of the lifting platform and is connected to the entire movement mechanism integrated platform through sheet metal and screws. The waste bin 28 is below the raw material A discharging motor 34. When the raw material A passes through the raw material A discharging motor 34, the A bottle can fall into the waste bin 28 by its own weight. The waste bin 28 is manually pluggable. After the waste bin is filled, after the lifting door 29 descends, the waste bin 28 can be taken out to pour out the used empty raw material A bottles. The lifting door 29 is fixed to the outermost side of the movement mechanism assembly through sheet metal and screws, and the lifting of the lifting door 29 is controlled by the lifting door 29 motor, lead screw and slide rail. The raw material A feeding bin 30, the raw material B burette 22, the lifting motor 32, the liquid taking valve assembly 33, and the raw material A discharging motor 34 are fixed to the movement platform through sheet metal and screws, and are in an overall up-and-down structure. The entire platform runs up and down driven by the lifting motor and lead screw. The container of raw material B, i.e., the B bottle, is located below the movement platform. The container filled with raw material B is driven by a robotic arm to rotate to the position where the raw material B burette extracts raw material B or the storage position of the container filled with raw material B; there is also 1 motor and a robotic arm. The robotic arm is connected with a capping and uncapping device for the container of raw material B, and the opening or closing of the container lid of the container filled with raw material B is controlled by the said capping and uncapping device.

[0073] The raw material C rotating motor 7 makes the C bottle swing on a horizontal plane. It swings to the stirring position, or the outlet position, or the titration position. The B bottle and the C bottle swing on a plane, which is convenient for the B bottle and the C bottle to alternately rotate to the titration position during the preparation process. The B bottle rotates to the titration position to suck the B raw material, and the C bottle rotates to the titration position to drip the B raw material, which is convenient for the conversion of different working positions of the B bottle and the C bottle during the preparation process, realizing automatic control.

[0074] The stirring device is fixed to the movement mechanism platform through screws. After the raw material C feeding control detects that there is raw material, after the upper computer confirms and closes the door, the program will issue an instruction to control the raw material C rotating motor 7 to rotate to the specified position for stirring or titration position.

[0075] The integrated design and top-down layout of the above components can not only effectively reduce costs, but also promote the efficient and stable operation of the equipment and reduce the failure rate. For example, the raw material A feeding bin 30, the raw material B burette 22, the lifting motor 32, and the raw material A discharging motor 34 are integrated on a lifting platform 42, and one lifting motor 32 can be used to complete the process of titrating raw material B and puncturing the raw material A bottle, reducing the investment of one motor, effectively reducing costs and the equipment failure rate. For example, the top-down layout of the activation reactor 27, the raw material A discharging motor 34, the liquid taking valve assembly 33, the raw material B bottle, and the raw material C bottle can not only effectively reduce the length of the hose, save costs, but also effectively reduce the liquid remaining in the hose during the liquid transportation process and improve the preparation accuracy.

[0076] The activation reactor 27 is used to activate raw material A. The activation reactor includes an activation reactor electrode drive plate unit, an activation reactor electrode, a liquid inlet / outlet unit, a gas inlet / outlet unit, and a liquid activation pool. The activation reactor electrode drive plate unit is located above the activation reactor electrode, and the liquid activation pool is located below the activation reactor electrode. The liquid activation pool and the activation reactor electrode form a sealed cavity. It also includes a cooling fan, an activation reactor housing, and a guard coil.

[0077] The material of the liquid activation pool is made of polytetrafluoroethylene. The air inlet, exhaust port, liquid discharge port, and liquid inlet are food-grade PP material tower heads, which are fastened to the liquid activation pool by threads. The activation reactor electrode drive plate unit includes an activation reactor electrode drive plate. The activation reactor electrode drive plate, activation reactor electrode, and liquid activation pool are fastened together by screws. The activation reactor housing covers the activation reactor electrode drive unit, activation reactor electrode, and liquid activation pool. There is a cooling fan on one side of the activation reactor housing, and cooling holes are provided on the device housing opposite the fan and on the other two sides. The fan works continuously during the operation of the activation reactor to ensure sufficient heat dissipation during the operation of the activation reactor.

[0078] The liquid discharge port 9 is placed at the bottom to fully drain the liquid without leaving any residue.

[0079] Working principle and process: During liquid feeding, the liquid of raw material A enters from the liquid inlet. The air inlet and liquid discharge port are closed, and the exhaust port is opened. The liquid can enter the bottom inverted pyramid-shaped liquid activation pool. Then, the activation reactor electrode drive plate unit drives the activation reactor electrode drive plate to discharge high voltage for activation. After activation is completed, the air inlet and liquid discharge port are opened, and the exhaust port and liquid inlet are closed. The air pump is connected to the air inlet through a silicone tube, and air is blown into the inverted pyramid-shaped liquid activation pool, and the liquid is discharged through the liquid discharge port. The solution of raw material A is injected into bottle C after being activated in the activation reactor. The injection duration is set to 30 seconds. During the injection of the activated liquid A, the stirring device 35 is instructed to work at the same time. The raw material B rotating motor 25 drives the raw material B cockpit to reset. After the injection of the activated liquid A into bottle C is completed, the raw material C rotating motor 7 is instructed to rotate to the titration position. The lifting motor drives the lead screw 35 to control the movement platform 21 to descend and stop above bottle C. At this time, the raw material B titrator 22 is directly opposite the bottle mouth of bottle C. The program instructs the lifting motor to press down the push rod of the raw material B titrator 22 to drop the liquid B into bottle C.

[0080] The raw material B titration device includes a push rod stroke sensor, an electric push rod, a moving platform, and a raw material B titrator 22. The electric push rod drives the moving platform to raise or lower the titrator push rod, thereby sucking the B solution from the B bottle and then dropping the B solution into the C bottle. The push rod stroke sensor is used to detect the stroke of the electric push rod, thereby realizing automatic control. The principle of the sensor is not limited, and the sensors of the existing technology can be used to achieve it. 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 provided with a separate moving platform for lifting and lowering, or can share a moving platform with the raw material A feeding bin 30.

[0081] The raw material B feeding device includes a raw material B rotating motor 9, a raw material B loading button, a robotic arm cockpit, and a B bottle, where the B bottle is the container containing the raw material B. The raw material B rotating motor 25 holds the B bottle through the robotic arm cockpit. The raw material B rotating motor 25 is used to control the swinging position of the B bottle, and swing the B bottle to the titration position below the titrator and / or the storage position of the B bottle according to the program setting. It also includes 1 motor, namely the raw material B cockpit cover motor, and a robotic arm. The robotic arm is connected with the container cover of the raw material B, and controls the opening or closing of the container cover containing the raw material B by controlling the lifting or lowering of the robotic arm.

[0082] The raw material B rotating motor 25 and the cockpit cover motor are industrial-grade standard servo motors, which are fixed on the movement frame through sheet metal. The two motors are fixed through sheet metal and screws to cooperate with the operation of the raw material B loading program. The complete working process of loading the raw material B is as follows: click the B loading button, the lifting motor 32 starts to rise to the preset position, the raw material B cockpit cover motor controls the robotic arm to lift the bottle cap of the B bottle, 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 robotic 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. At this time, the B feeding is completed.

[0083] The raw material B rotating motor 25 holds the B bottle through the robotic arm cockpit, removes the bottle 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 sucks the B solution, then moves the B bottle back to the storage position, covers the bottle cap, and the raw material C rotating motor 7 swings the C bottle containing the activated water and C powder that has been preliminarily stirred to the titration position below the raw material B titrator 22, drops the B solution. After the titration is completed, the raw material C rotating motor 7 swings the C bottle to the stirring position and starts stirring again. After stirring for a predetermined time, generally 5 - 10 minutes, the tooth whitening gel is prepared. Each part of the device cooperates with each other to achieve the effect of non-contact and automatic stirring of the liquid in a closed space.

[0084] Example 2

[0085] Figures 15 - 16 Another magnetic stirring structure. This structure can drive the stir bar 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 transmission of 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 rotation of the rotating arm 25 attracts the stir bar 3 to stir the raw materials in the bottle. At the same time, the up and down movement of the electric push rod 12 drives the lifting of the rotating arm 26. The lifting of the rotating arm is fixed to the fixed frame 11 through the slider 16. The nylon protective sleeve 13 functions to protect the safety of the bottle.

[0086] The structure cooperating with the above two stirring embodiments further includes a raw material A feeding device, an activation reaction device, and a raw material B titration device. The raw material A enters the activation reaction device through the raw material A feeding device for activation, and after activation, it enters the stirring device. Before the secondary stirring, the raw material B is dropped into the stirring device through the raw material B titration device, and then fully stirred to automatically prepare the teeth whitening gel.

[0087] Raw material A, raw material B, and raw material C respectively represent a raw material or a mixture of several raw materials.

[0088] Raw material A is a hydrogen peroxide solution with a concentration of 2.5% - 6%, and the optimal 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 5 ml. Raw material B is a neutralizing agent, and the main component is a sodium hydroxide solution with a concentration of 10%. It is canned in a vial sealed with a rubber stopper, that is, bottle B, and the volume of bottle B is 8 ml. Raw material C is carbomer, with a mass of 0.02 - 0.08 g, and the optimal amount for a single preparation is 0.04 g. Raw material C and the stir bar are placed in a vial, and vial C is a vial. In the teeth whitening gel preparation machine of this patent, the distance that the motor drives the lifting platform has good repeatability. There will be a fixed liquid residue in bottle A. During a single preparation process, 3 ml of raw material A is used, and there is approximately 0.2 ml of liquid A residue, about 0.2 ml of raw material B, and 0.04 g of raw material C. It requires 5 - 10 minutes for the activation time, and the optimal time is 7 or 8 minutes, at which time the performance of the activated water reaches a stable state. The volume ratio of the hydrogen peroxide solution to the neutralizing agent is 15:1, and this ratio has just the right consistency to adhere to the teeth and the appropriate pH value. The stirring time is generally 5 - 10 minutes.

[0089] Ratio 1: 3.2 ml of hydrogen peroxide solution with a concentration of 2.5%, 0.2 ml of neutralizing agent with the main component being 10% sodium hydroxide solution, 0.02 g of carbomer.

[0090] Ratio 2: 3.2 ml of hydrogen peroxide solution with a concentration of 3%, 0.2 ml of neutralizing agent with the main component being 10% sodium hydroxide solution, 0.04 g of carbomer.

[0091] Ratio 3: 3.2 ml of 6% hydrogen peroxide solution, 0.2 ml of a neutralizing agent which is mainly 10% sodium hydroxide solution, and 0.08 g of carbomer.

[0092] The teeth whitening gels prepared from the above three ratios through the teeth whitening gel preparation mechanism of the present application can be directly coated on the tooth surface, and the effect differences are not significant. The effect of Ratio 3 is the best. It does not require a gum protector, has a definite teeth whitening effect, and can greatly reduce the risks of common allergies and post-whitening soreness caused by high-concentration hydrogen peroxide gels.

[0093] Clinical results show that the whitening gels and whitening liquids prepared using the equipment of the present application are non-toxic, non-irritating, and odorless. There is no residual gel after rinsing after whitening, and they have a good teeth whitening effect.

[0094] The teeth whitening effect can be adjusted by adjusting the concentration of hydrogen peroxide solution in Raw Material A, the activation time of the activation reactor, the thickness of the gel coated on the teeth, and the time for the gel to act on teeth whitening.

[0095] The 40 subjects participating in the clinical trial had yellow teeth with ordinary 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 from Formula 2 and the equipment of the present application. The control group used 3 ml of ultrapure water to replace the activated Raw Material A, the neutralizing agent was 0.2 ml of 10% sodium hydroxide solution, and 0.04 g of carbomer, and the gel was prepared manually.

[0096] The whitening method was to coat the gel on the tooth surface in 3 times for each person, with each whitening time being 15 minutes. During the process, a cold light lamp was used for catalytic stimulation, and the total action time was 45 minutes. None of the subjects used a gum protector before whitening and a desensitizer after whitening.

[0097] The whitening effect was mainly judged and analyzed using the VITA Bleachedguide 3D-Master colorimetric board, which is a commonly used intuitive visual effect analysis method in clinical practice.

[0098] The color of the teeth is determined by three values: brightness, color saturation, and color value through colorimetric comparison with the colorimetric board (here, the Vita colorimetric board is used as an example). The M column is the intermediate 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 among the 5 groups of 1, 2, 3, 4, and 5. Second, compare the saturation vertically and find the one with the best saturation. Then compare the color value horizontally.

[0099] The teeth whitening gel prepared by the equipment of the present application has an excellent whitening effect. The color difference ΔE of the teeth before and after whitening can be 3 to 8 color scales, and none of the participating subjects had a sense of soreness after the operation.

[0100] The control group followed the same method of gel application and colorimetry. The difference in tooth color scale ΔE before and after whitening increased by nearly 0 color scale.

[0101] 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 conducted. An independent samples 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, and the significance level was α = 0.05. The difference in tooth color scale ΔE before and after whitening in the sample group was 3.90 ± 1.14. The difference in tooth color scale ΔE before and after whitening in the control group was 0.00 ± 0.00. There was a very significant difference in the color scale change after using the product between the sample group and the control group (P < 0.01), indicating that there was a very significant difference in the effect of the tooth whitening gel prepared by this mixing equipment compared with the control group.

[0102] The gel prepared by the patented equipment of the present invention can be used in scenarios such as dental clinics, stomatological hospitals, and medical aesthetic institutions to assist doctors in performing cold light bleaching reactions on yellow teeth, sensitive teeth, tea-stained teeth, smoke-stained teeth, and endogenous fluorosis teeth and tetracycline teeth, decomposing the pigment groups on the tooth surface and restoring the natural color of the teeth. It can also be used to kill bacteria and viruses on various skin surfaces or oral mucosae, such as treating inflammatory infections such as acne and gingivitis.
