Description

Technical Field

[0001] The invention relates to dentistry and tooth hygiene devices, and in particular to a tooth whitening gel preparation machine and a tooth whitening gel preparation method. Background Art

[0002] Cold light whitening technology is a teeth whitening method that uses cold light of a specific wavelength to irradiate teeth, accelerate the penetration and reaction of whitening agents, and quickly remove pigment deposits on the surface and deep layers of teeth. It has significant effects and is relatively easy to operate, and is favored by many people who pursue teeth whitening.

[0003] The main ingredients of the whitening agent used in cold light whitening technology are hydrogen peroxide (usually at a concentration of 17%-35%), and possible auxiliary ingredients such as silicon dioxide. Hydrogen peroxide is a strong oxidant that can quickly produce a redox reaction under the irradiation of cold light, releasing free oxygen. These free oxygen can penetrate into the enamel of the teeth, combine with the pigment molecules on the surface of the teeth, and decompose them into colorless small molecules, thereby achieving a whitening effect.

[0004] Due to the improvement of the whitening agent formula and the improvement of penetration ability, the whitening technology can provide a longer-lasting whitening effect and reduce the need for patients to undergo frequent whitening treatments. Compared with traditional cold light whitening technology, whitening technology significantly reduces the risk of post-operative sensitive pain and tooth damage, and improves the overall comfort of patients. Although whitening technology has been optimized in many aspects, it still cannot completely avoid some potential problems in traditional teeth whitening technology. In particular, the use of high concentrations of hydrogen peroxide, even if it is reduced in whitening technology, the high concentration may still cause some damage to the teeth.

[0005] Although low concentrations of hydrogen peroxide cause less damage to teeth, their whitening effects are often not obvious and last for a short time. This dilemma of high concentrations causing greater damage and low concentrations causing poor results is a technical problem that needs to be solved urgently.

[0006] The existing method of low-temperature plasma activation of hydrogen peroxide solution is to use a certain flow of high-voltage discharge gas to inject into the hydrogen peroxide solution. Due to the certain transmission distance and time, and the short survival time of the active ingredients, a large amount of active ingredients will be lost in the process, and the absorption efficiency is low, so the activation time is relatively long. This method will continue to produce long-lived ozone and nitrogen oxides, which will diffuse indoors, causing indoor air pollution and causing certain harm to the health of indoor personnel. Summary of the invention

[0007] The main purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide an activation reactor 13, which includes an activation reactor 13, wherein the activation reactor 13 includes an activation reactor electrode driving plate unit, an activation reactor electrode 5, an inlet and outlet liquid unit, an inlet and outlet gas unit, and a liquid activation pool 8; the activation reactor electrode driving plate unit is located at the upper part of the activation reactor electrode 5, and the liquid activation pool 8 is located at the lower part of the activation reactor electrode 5; the liquid activation pool 8 and the activation reactor electrode 5 form a closed cavity.

The active ingredients produced by the discharge of the activation reactor electrode 5 only need to diffuse into the raw material A solution through a distance of 5-10mm, and the activation efficiency is extremely high. Therefore, the activation time only takes 5-10 minutes. The time required by the prior art is relatively long, and some are as long as 20 to 30 minutes. The use feature of the teeth whitening gel machine of the present application is that the teeth whitening gel machine is prepared on-site by dental clinics or hospitals and other institutions, and is used on-site by users.

DETAILED DESCRIPTION

[0038] The following is a description of the definitions, connection modes, working principles and processes of each unit module of the present invention, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, those skilled in the art should recognize that various modifications and changes can be made to the embodiments described herein without departing from the scope and spirit of the present invention.

[0039] The modules, units, mechanisms, devices, etc. involved in the application documents of this application are not limited to specific software or hardware environments, and they are highly abstract and flexible. Whether it is a software module that relies on software programs to run to achieve specific functions, or a hardware unit built based on physical circuits, mechanical structures, etc., they are all within the scope of the application documents. 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. Example 1

[0040] The present invention provides a tooth whitening gel preparation machine, comprising an activation reactor 13, wherein the activation reactor 13 comprises an activation reactor electrode driving plate unit, an activation reactor electrode unit, a liquid inlet and outlet unit, a gas inlet and outlet unit, and a liquid activation pool 8; the activation reactor electrode driving plate unit is located at the upper part of the activation reactor electrode 5, and the liquid activation pool 8 is located at the lower part of the activation reactor electrode 5; the liquid activation pool 8 and the activation reactor electrode 5 form a closed cavity.

[0041] like Figure 1-2 As shown, the activation reactor electrode driving plate unit includes an activation reactor electrode driving plate 4, and the liquid inlet and outlet unit includes a liquid discharge port 9, a liquid inlet 10, an air inlet 6, an air outlet 7, and a liquid activation pool 8. The liquid activation pool 8 and the activation reactor electrode 5 form a closed cavity. It includes an activation reactor shell 2; and also includes a protective coil 3 for protecting the pipeline.

[0042] The activation reactor electrode driving unit is located on the upper part of the activation reactor electrode 5, and the liquid activation pool 8 is located on the lower part of the activation reactor electrode 5. Such a positional relationship will not corrode the activation reactor electrode plate and is conducive to the activation of raw material A.

[0043] The liquid activation pool 8 is made of polytetrafluoroethylene, and the air inlet 6, the exhaust port 7, the drain port 9, and the liquid inlet 10 are pagoda heads made of food-grade PP material, which are fastened to the liquid activation pool 8 by threads. The activation reactor electrode drive plate unit includes the activation reactor electrode drive plate 4, and the activation reactor electrode drive plate 4, the activation reactor electrode 5 and the liquid activation pool 8 are fastened together by screws. The activation reactor shell 2 covers the activation reactor electrode drive unit, the activation reactor electrode 5, and the liquid activation pool 8. A cooling fan 1 is provided on one side of the activation reactor shell 2, and cooling holes are provided on the activation reactor shell 2 opposite to the fan and on the other two sides. The fan continues to work during the working process of the activation reactor 13 to ensure that the activation reactor 13 is fully cooled during the working process.

[0044] The drain port 9 is placed at the bottom to fully drain the liquid without any residual liquid.

[0045] Working principle and process: When adding liquid, the raw material A liquid enters from the liquid inlet 10, the air inlet 6 and the liquid discharge port 9 are closed, and the exhaust port 7 is opened, so that the liquid can enter the inverted pyramid-shaped liquid activation pool 8 at the bottom. Then the activation reactor electrode driving plate unit drives the activation reactor electrode 5 to discharge with high voltage for activation. After the activation is completed, the air inlet 6 and the liquid discharge port 9 are opened, and the exhaust port 7 and the liquid inlet 10 are closed. The air pump is connected to the air inlet 6 through a silicone tube, blows air into the inverted pyramid-shaped liquid activation pool 8, and discharges the liquid out through the liquid discharge port 9. The raw material A solution is activated by the activation reactor 13 and then injected into the C bottle. The injection time is set to 30 seconds. During the injection of the activated A solution, the stirring device 37 is instructed to work at the same time, and the raw material B rotating motor 35 drives the raw material B cabin to reset. After the activated A solution is injected into the C bottle, the raw material C rotating motor 36 is instructed to rotate to the titration position, and the lifting motor 33 drives the screw rod to control the motion platform to fall to the top of the C bottle and stop. At this time, the raw material B titrator 32 is facing the bottle mouth of the C bottle. The program instructs the lifting motor 33 to press down the push rod of the raw material B titrator 32 to drop the B solution into the C bottle.

[0046] like Figure 3 , Figure 4 As shown, it also includes a raw material A feeding device for supplying raw material A to the activation reactor 13. The sheet metal bracket 21 is the silo floor, and both the raw material A discharge motor 15 and the material shortage detection sensor 16 are fixed with screws.

[0047] It includes a raw material A loading bin 31, a raw material A discharging motor 15, an A bottle feeding dial 14, a bottle dialing shaft 20, and an A bottle 18. The container containing the raw material A is referred to as the A bottle 18.

[0048] The raw material A loading bin 31 is used to cache the raw material A. The raw material A is placed in the A bottle 18. After the raw material A is extracted, the empty A bottle 18 will be automatically discarded to the waste bin 29 before the next preparation. The waste bin 29 is a device for collecting and storing the empty A bottle 18 after the A liquid is extracted.

[0049] The raw material A discharging motor 15 is used to drive the loading of the A bottles 18 and the discarding of the A bottles 18 .

[0050] The A bottle feeding dial 14 is integrated on the raw material A loading bin 31 and is used for aligning the discarded bottles and the loading of the A bottles 18 .

[0051] The raw material A feeding device includes a raw material A feeding bin 31, 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, that is, the activation reactor 13 is arranged at one end of the feeding position of the raw material A feeding bin 31. The raw material A feeding bin 31 is provided with a sheet metal base and a light shielding cover 11. The sheet metal base is affixed with a polytetrafluoroethylene slide to facilitate the downward sliding of the A bottle 18 during the feeding process. The sheet metal base can also be other relatively smooth materials, not limited to polytetrafluoroethylene. The light shielding cover 11 and the base are connected by screws. The light shielding cover 11 can be opened during feeding, and the light shielding cover 11 can be closed after feeding. The function of the light shielding cover 11 is to prevent the raw material A from being exposed to light and to preserve the quality of the raw material A. The raw material A discharge motor 15 and the bottle A feed dial 14 and the bottle dial shaft 20 are connected by screws, and the raw material A discharge motor 15 drives the bottle A feed dial 14 and the bottle dial shaft 20 to rotate. There are 6 evenly distributed grooves on the bottle dial shaft 20, and the curvature of each groove corresponds to the curvature of the bottle body of the bottle A 18. The bottle A 18 is driven to rotate by the rotation of the bottle dial shaft 20. The bottle A feed dial 14 is provided with 6 evenly distributed holes, which correspond to the 6 grooves driving the bottle A feed dial 14, that is, the raw material A discharge motor 15 rotates the bottle A feed dial 14 and the bottle dial shaft 20 rotates 60 degrees, the bottle A feed dial 14 rotates from one hole to the position of the adjacent hole, and the bottle dial shaft 20 rotates from one groove corresponding to the feeding position of the bottle A 18 to the next groove corresponding to the feeding position of the bottle A 18. A dial position sensor 19 is arranged on the upper part of the A bottle feeding dial 14. The raw material A discharging motor 15 rotates the A bottle feeding dial 14 and the bottle dialing shaft 20, and passes through the hole of the A bottle feeding dial 14 at a fixed angle of 60 degrees. The dial position sensor 19 senses whether it is rotated to the adjacent hole of the A bottle feeding dial 14. Once it is rotated to the hole position, it is determined that it has been rotated to the set position and stops rotating. The dial position sensor 19 can be a photoelectric sensor, which relies on photoelectric sensing to determine whether it is rotated to the set position of the A bottle feeding dial 14. Because the raw material A discharging motor 15 rotates the A bottle feeding dial 14 and the bottle dialing shaft 20 at the same time, once the raw material A discharging motor 15 rotates to an adjacent hole position, the bottle dialing shaft 20 brings the A bottle 18 to the feeding position. The material shortage detection sensor 16 can be a photoelectric sensor or a gravity sensor. After detecting the presence of bottle A 18, the raw material A discharging motor 15 drives the bottle A feeding dial 14 and the bottle dial shaft 20 to rotate a fixed angle to a fixed position, and the bottle dial shaft 20 brings bottle A 18 to the loading position, that is, the position for extracting raw material A.

[0052] A bottles 18 are loaded one by one by sliding down from the raw material A loading bin 31. Raw material A is sealed in a smooth bottomed vial, i.e., A bottle 18, with an aluminum-plastic cover.

[0053] It also includes a motion platform, and the raw material A loading bin 31 is set on a motion platform, and the motion platform is driven to rise and fall by a lifting motor 33. When sucking raw material A, the platform lifting motor 33 drives the raw material A loading bin 31 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 31 rises to a fixed position, the raw material A liquid collection needle assembly 12 is inserted into the A bottle 18.

[0054] 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 13 after extraction. The activation reactor 13 is placed in the middle position of the teeth whitening gel preparation machine, which is also convenient for the activated liquid to smoothly enter the C raw material bottle to prevent the occurrence of reflux.

[0055] The raw material A loading bin 31 is arranged on a moving platform, and the moving platform is driven to rise and fall by a lifting motor 33 .

[0056] The lifting motor 33 shown in Fig. 1 and Fig. 2 is a stepper motor, which is located directly below the motion platform, fixed to the movement frame by screws, and connected to the motion platform by couplings and screws. The motion platform integrates components such as the raw material A loading bin 31, the raw material B titrator 32, and the raw material A discharging motor 15. Each component is fixed to the motion platform by sheet metal fixings and screws. The entire module presents an up-and-down structure, and the motor controls the lifting and lowering operation of the entire lifting platform through couplings and screws. Then, the raw material A loading bin 31 and the raw material B titrator 32 are indirectly controlled to move up and down. The working procedures of the lifting motor 33 and the raw material A loading bin 31 are set as follows: a smooth polytetrafluoroethylene patch is affixed to the bottom of the raw material A loading bin 31. After the raw material A bottle 18 is loaded, the raw material A bottle 18 slides into the groove of the bottle shifting shaft 20 by its own weight. The sensor recognizes the raw material A bottle 18, and the program instructs the bottle shifting shaft 20 to rotate the A bottle 18 to the loading position. The lifting motor 33 drives the screw rod to control the entire lifting platform to rise, so that the raw material A loading bin 31 containing the A bottle 18 rises, while the raw material A liquid extraction needle assembly 12 does not move, so that the air needle curved needle head 26 and the liquid needle straight needle head 25 of the raw material A liquid extraction needle assembly 12 are inserted into the A bottle 18, and the air needle curved needle head 26 is connected to the diaphragm pump through a hose, and starts to blow air into the closed A bottle 18. The liquid needle straight needle head 25 is inserted into the bottom of the A bottle 18 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 needle straight needle head 25 and the pipeline. The design of gas-liquid double needle piercing and pressurized extraction is adopted for extracting raw material A liquid. This design can ensure that liquid A is in a fully closed 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 turned upside down 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 13 along the direction of the pressure pipeline.

[0057] The activation reactor 13 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 29 is below the raw material A discharge motor 15. When the raw material A passes through the raw material A discharge motor 15, the A bottle 18 can fall into the waste bin 29 by its own weight. The waste bin 29 is manually pluggable. When the waste bin 29 is filled, the lifting door 30 is lowered, and the waste bin 29 can be taken out and the used raw material A empty bottle can be poured out. The lifting door 30 is fixed to the outermost side of the movement assembly by sheet metal and screws, and the lifting and lowering of the lifting door 30 is controlled by the lifting door 30 motor, screw rod and slide rail. The raw material A loading bin 31, the raw material B titrator 32, the lifting motor 33, the valve group 34, and the raw material A discharge motor 15 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 33 and the screw rod. The container of raw material B, i.e., bottle B, is located below the moving platform. The container containing raw material B is driven by a robotic arm to rotate to the position where the raw material B titrator 32 extracts raw material B or to the storage position of the container containing raw material B; the container decapping device for raw material B also has a motor and a robotic arm. The robotic arm is connected to the container cover decapping device containing the container containing raw material B, and the container cover containing raw material B is controlled to be opened or closed through the decapping device.

[0058] like Figure 5 As shown, the raw material A liquid extraction needle assembly 12 includes a gas needle curved needle head 26, a liquid needle straight needle head 25, a needle holder 27, a Luer connector 28, and a bracket three 22, a bracket two 23, and a bracket 24.

[0059] The raw material A liquid extraction needle assembly 12 includes a three-layer bracket, which is used to adjust the position of the gas needle curved needle head 26 and the liquid needle straight needle head 25; the bracket 24 for fixing the gas needle curved needle head 26 and the liquid needle straight needle head 25 is used to adjust the left and right positions of the gas needle curved needle head 26 and the liquid needle straight needle head 25; the middle bracket 23 is used to adjust the front and back positions of the gas needle curved needle head 26 and the liquid needle straight needle head 25; the outermost bracket three 22 is used to adjust the up and down positions of the gas needle curved needle head 26 and the liquid needle straight needle head 25, that is, the depth of the liquid needle straight needle head 25 inserted into the A bottle 18, to ensure that the liquid in the raw material A bottle 18 is fully discharged.

[0060] The setting of the bracket 3 22 adjusts the vertical position of the entire liquid extraction module by lengthening the fixing screw hole to ensure that the liquid in the raw material A bottle 18 is fully discharged. The needle holder 27 fixes the gas needle curved needle 26 and the liquid needle straight needle 25 on the bracket 24 through 4 screws, and the raw material A liquid extraction needle assembly 12 is fixed on the raw material A feeding unit sheet metal.

[0061] The design of double-needle insertion and pressurized extraction of liquid A using a curved gas needle 26 and a straight liquid needle 25 can ensure that liquid A 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 turned upside down to extract all the solution.

[0062] How it works The low concentration hydrogen peroxide liquid (liquid A) solution is input into the activation reactor 13 through the switch of the gas-liquid valve to perform a plasma activation reaction to enhance its activity and redox ability. The activated hydrogen peroxide liquid and powder (in bottle C) and another raw material (liquid B) are mixed by the stirring device 37 and stirred to prepare a gel.

[0063] The stirring device 37 includes a raw material C rotating motor 36, a C bottle, a mechanical arm, a raw material C cabin, a magnetic stirring bar, and a rotating head with a permanent magnet. The C bottle refers to a container for holding the raw material C, which can be a bottle or a container of other shapes.

[0064] The base of the stirring device 37 has two magnetic poles. The motor drives the base to rotate, and the magnetic poles of the base attract the magnetic stirring bar in the C bottle to rotate.

[0065] The stirring device 37 motor is connected to the rotating head, and a permanent magnet is arranged inside the rotating head. The stirring rod is arranged in the C bottle.

[0066] The inside of the stirring rod is a permanent magnet or magnetic material, and the outer layer is wrapped with polytetrafluoroethylene material, which is either smooth or rough coated.

[0067] The permanent magnets in the rotating head are set at positions corresponding to the stirring rods. If the stirring rod is in the shape of a long pill, two permanent magnets are set symmetrically at 180 degrees. If the stirring rod is cross-shaped, the permanent magnets in the rotating head can be set every 90 degrees, for a total of 4. In short, the permanent magnets in the rotating head drive the stirring rod to rotate by magnetic attraction.

[0068] It also includes a raw material C loading device, which includes a raw material C rotating motor 36, an infrared photoelectric sensor, a lifting door 30, and a raw material C cabin.

[0069] The raw material C rotating motor 36 is an industrial standard servo, which is fixed on the component base platform by sheet metal. The motor and the base are fixed by sheet metal to cooperate with the loading and identification procedures of raw material C. The workflow of loading raw material C is as follows: in the upper computer operation interface, click the Load C button on the right, the lifting door 30 drops to the preset position, and the raw material C cabin is exposed (initialization position). The RFID module is used for coding and tracing of raw material C bottles. Bring the C bottle containing raw material C close to the RFID module for identification to detect the information and expiration date of the C bottle, and upload the detection and verification information to the cloud server. After verification, put the C bottle into the raw material C cabin. The infrared sensor detects the presence of the C bottle, and the next procedure can be carried out. Click to close the cabin door according to the prompt, and the lifting door 30 rises to the preset position. At this time, the loading of raw material C is completed.

[0070] The raw material C rotating motor 36 drives the raw material C cabin to open automatically when it is in place at the outlet, and rotates to the stirring position and the titration position after the C bottle is placed, and automatically clamps the C bottle after leaving the outlet.

[0071] The raw material C rotating motor 36 is a mechanism for providing power. The raw material C cockpit is controlled by the raw material C rotating motor 36, and the device can fix or loosen the C bottle. The raw material C cockpit is controlled by the raw material C rotating motor 36 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.

[0072] After the stirring is completed at the stirring position, the raw material C cockpit is controlled by the raw material C rotating motor 36 to swing the C bottle to the exit position of the C bottle, and the raw material C cockpit on the mechanical arm hits the limit block, and the cockpit's clamping force on the bottle becomes smaller, so that the bottle is in a loose and removable state. After the teeth whitening gel is prepared, the lifting door 30 is lowered, and the C bottle containing the teeth whitening gel can be taken out.

[0073] The liquid device vacancy detection sensor detects whether bottle C exists, and the swing position sensor detects the position of bottle C, thereby realizing automatic control of bottle C for stirring. The principle of the sensor is not limited, and it can be realized by using sensors of the prior art. When bottle C is injected with the activated aqueous solution of raw material A activated from the activation reactor 13 at the stirring position, after the activated water and raw material C are initially stirred, bottle C is rotated to the titration position to drip the raw material B solution, and then rotated back to the stirring position to continue stirring, and finally the prepared teeth whitening gel is taken out at the outlet position for use.

[0074] It also includes a titration device for raw material B, which includes a push rod stroke sensor, an electric push rod, a motion platform, and a raw material B titrator 32. 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 32 is used to accurately set the volume of the titrated B raw material. The raw material B titrator 32 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 31.

[0075] It also includes a raw material B loading device, which includes a raw material B rotating motor 35, 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 35 clamps the B bottle through the mechanical arm cockpit, and the raw material B rotating motor 35 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 controlled to be opened or closed by controlling the mechanical arm to lift or descend.

[0076] The raw material B rotating motor 35 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 33 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 35 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 35, click the raw material B loading switch again, the raw material B rotating motor 35 rotates 90° counterclockwise to the B bottle storage position, and the lifting motor 33 descends to the preset position, and the B loading is completed.

[0077] The raw material B rotating motor 35 clamps the B bottle through the robot cockpit, removes the bottle cap of the B bottle, swings the B bottle to the titration position below the raw material B titrator 32, the raw material B titrator 32 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 36 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 32, drips the B solution, and after the titration is completed, the raw material C rotating motor 36 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 devices cooperate with each other to achieve the effect of contactless and automatic stirring of liquids in a closed space.

[0078] The overall composition of a teeth whitening gel preparation machine includes a touch screen, which is located in the upper front of the device, is easy to operate, and is used for human-computer interaction, the start of teeth whitening gel preparation and the preparation status display, and the preparation time display. It can also be used to test the preparation machine. The outer shell is a protective shell of the teeth whitening gel preparation machine, which is used to protect the internal components of the device. It has a beautiful appearance and is easy to operate and carry. The buckle handle and the drag handle facilitate the transportation and movement of the teeth whitening gel preparation machine. The operation indicator light is used to display the operation status of the device.

[0079] The upper computer microcomputer is a platform for human-computer interaction and server interaction, and it also needs to send corresponding action instructions to the lower computer electronic control for execution. The lower computer electronic control is mainly used for preparing logic program control and signal detection and judgment.

[0080] The movement assembly includes a motion platform that is assembled with all actuators, motors, and sensors, so that the teeth whitening gel preparation machine can automatically prepare teeth whitening gel. The actuators include liquid and steam valves and robotic arms. The power distribution control box is located below the movement assembly to supply power to various components of the equipment.

[0081] The valve group 34 is a valve control module for controlling the on and off of the gas source and switching the gas circuit and the liquid circuit.

[0082] The valve group 34 is located at the upper and back of the device. The valve group 34 is a general term for all valves. In this application, the opening or closing of the valve group 34, or the valve group 34 mentioned somewhere, refers to the valve corresponding to the step of opening or closing the device or equipment, not all valves.

[0083] Traditionally, solenoid valves are used in liquid and gas circuits. Solenoid valves have a short service life, a complex structure, and are prone to problems. If they are opened for a long time, they will heat up or burn out.

[0084] The servo steering gear method adopted by the valve group 34 of the present application controls the valves in series through bus communication, and the circuit is simple and easy to maintain. At the same time, the flow rate can be controlled by controlling the angle of the valve. Since the mechanical rotation plus angle control servo steering gear solution is adopted, the valve switch can maintain a state for a long time, and there is no situation of long-term power-on heating or even burning. The servo steering gear is installed on the bracket to control the switch of the valve. The mechanical valve is completely isolated from the servo motor to prevent liquid from corroding the circuit components.

[0085] The liquid extraction valve assembly controls the raw material A liquid extraction needle assembly 12 through the A bottle liquid extraction gas valve assembly to allow the raw material A in the A bottle 18 to enter the activation reactor 13. After activation is completed, the activated water is controlled by the activation reactor 13 exhaust valve assembly, the C bottle liquid injection valve assembly, and the C bottle liquid injection gas valve assembly, and is injected into the C bottle through the injection needle assembly. Example 2

[0086] A teeth whitening gel preparation system comprises the teeth whitening gel preparation machine described in any one of the above embodiments, and also comprises a cloud server for managing the operation status of the equipment and the preparation data and data storage.

[0087] The gel prepared by the device of this application 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. Example 3

[0088] A method for preparing a teeth whitening gel, the method is used for a teeth whitening gel preparation machine described in any one of the above embodiments, wherein a raw material A with a concentration of 2.5%-6% is injected into an activation reactor for activation, wherein the raw material A is a hydrogen peroxide solution; after activation, the activated solution is injected into a raw material C, wherein the raw material C is carbomer; raw material B is dripped before secondary stirring, wherein the raw material B is a neutralizer, and then the mixture is fully stirred to prepare a teeth whitening gel; in a single preparation process, the volume ratio of the hydrogen peroxide solution to the neutralizer is 15:1. By touching the display screen of a teeth whitening gel preparation machine and clicking the automatic activation button, the program controls the lifting door to start descending, and the raw material C rotating motor 36 controls the mechanical arm to work to the exit. After the action is completed, the instruction is returned to the touch display screen, indicating that the filling can be performed. After the filling is completed, the touch display screen is clicked to confirm that the C bottle is placed, and at the same time, the device detects whether the C bottle is placed. The C bottle is a container containing the raw material C. After the detection of successful placement, the production date is recorded and the validity period is set. The lifting door 30 is controlled to start rising and the hatch is closed. Enter the password to start issuing instructions to start the preparation.

[0089] like Figure 6 As shown, at the beginning of the preparation, the raw material A discharge motor 15 drives the A bottle feed dial 14 to rotate, and the raw material A in the raw material A loading bin 31 is transported to the designated position, that is, the raw material A extraction loading position. The extracted waste A bottle 18 is discarded into the A bottle waste bin 29. The A bottle waste bin 29 collects the container from which the raw material A has been extracted. After this action is completed, the lifting motor 33 starts to rise and enters the extraction position. Open the valve and pressurize to extract the raw material A into the activation reactor 13. Wait until the liquid is extracted and start the activation reactor 13 to activate the work, and the lifting motor 33 starts to descend. At this time, the raw material C rotating motor 36 runs the C bottle to the canning position through the mechanical arm, and the canning position and the stirring position are the same position. The raw material B rotating motor 35 runs the B bottle to the titration position through the mechanical arm, and the raw material B titrator 32 absorbs the raw material B and waits for titration. The B bottle is the container containing the raw material B.

[0090] After the activation reactor 13 is activated, the valve is opened to pressurize the activated raw materials into the container of raw material C, that is, bottle C, and the stirring device 37 starts magnetic stirring. After the canning is completed, the lifting motor 33 starts to drive the raw material B titrator 32 to rise, the raw material B rotating motor 35 moves bottle B to the storage position through the mechanical arm, and the raw material C rotating motor 36 moves bottle C to the titration position through the mechanical arm. The raw material B titrator 32 titrates the absorbed raw material B into the bottle C after the canning is completed. After the titration is completed, the raw material C rotating motor 36 moves bottle C to the stirring position through the mechanical arm, and the preparation is completed after continuing the magnetic stirring.

[0091] After the preparation is completed, the touch screen will display the countdown and prompt completion. Click the hatch door opening button to control the lift door 30 to start descending, and the raw material C rotating motor 36 will transport the C bottle to the exit position through the mechanical arm. Then the finished product can be taken out.

[0092] Raw material A, raw material B, and raw material C represent one raw material or a mixture of several raw materials respectively.

[0093] 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, i.e., bottle A 18, and the volume of bottle A 18 is 5ml. Raw material B is a neutralizer, 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, i.e., bottle B, and the volume of bottle B is 8ml. Raw material C is carbomer, and the mass is 0.02-0.08g. The best single preparation is 0.04g. Raw material C and a stirrer are contained in a vial, and bottle C is a vial. In the tooth whitening gel preparation machine of the present application, the distance repeatability of the lifting platform driven by the motor is good. Bottle A 18 will have a fixed liquid residue, and 3ml of raw material A will be used in a single preparation process, about 0.2ml of A liquid residue, about 0.2ml of raw material B, and 0.04g of raw material C. 5-10min activation time is required, 7 or 8min is optimal, and the performance of activated water reaches a stable state at this time. 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] Clinical results show that the whitening gel and whitening solution prepared by the device of the present invention are non-toxic, non-irritating, and odorless, and no residual gel is left after rinsing after whitening, and have a good teeth whitening effect.

[0099] 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 13, the thickness of the gel coating on the teeth, and the time the gel acts on the teeth for whitening.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] The control group followed the same gel application and colorimetry method, and the color difference ΔE of teeth before and after whitening increased to close to 0 color level.

[0106] 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 device was significantly different from that of the control group.
