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 irradiates teeth with cold light of a specific wavelength to accelerate the penetration and reaction of whitening agents, thereby quickly removing pigment deposits on the surface and deep layers of the teeth.

[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

[0008] Different from the prior art, the activation reactor electrode 5 and the raw material A solution of the present application, such as the raw material A solution being hydrogen peroxide solution, are sealed in a cavity. The distance between the activation reactor electrode 5 and the raw material A solution is very short, only 5-10 mm. The active components generated by the discharge of the activation reactor electrode 5 only need to diffuse into the raw material A solution through a distance of 5-10 mm, and the activation efficiency is extremely high. Therefore, the activation time only needs 5-10 minutes. The prior art requires a longer time, some up to twenty or thirty minutes. The usage feature of the teeth whitening gel machine of the present application is that it is prepared on-site in institutions such as dental clinics or hospitals for on-site use by users. The preparation time is particularly important. A short preparation time shortens the waiting time of users and can also receive more users within the effective time.

Detailed implementation manners

[0044] The following descriptions are made on the definitions, connection methods, 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, and they should be considered 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.

[0045] In the application documents of the present application, the modules, units, mechanisms, devices, etc. involved are not limited to a specific software or hardware environment, and 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 the application documents of the application. The description of their functions and logics focuses on the overall design concept, operation process, and achievable effects and goals, rather than being limited to specific software and hardware implementation forms. Embodiment 1

[0046] The present invention provides a tooth whitening gel preparation machine, including an activation reaction kettle 13, and the activation reaction kettle 13 includes an activation reaction kettle electrode drive board unit, an activation reaction kettle electrode unit, a liquid inlet and outlet unit, a gas inlet and outlet unit, and a liquid activation pool 8; the activation reaction kettle electrode drive board unit is located above the activation reaction kettle electrode 5, and the liquid activation pool 8 is located below the activation reaction kettle electrode 5; the liquid activation pool 8 and the activation reaction kettle electrode 5 form a sealed cavity.

[0047] As Figure 1-2 shown, the activation reaction kettle electrode drive board unit includes an activation reaction kettle electrode drive board 4, the liquid inlet and outlet unit includes a liquid discharge port 9, a liquid inlet port 10, a gas inlet 6, an exhaust port 7, and a liquid activation pool 8. The liquid activation pool 8 and the activation reaction kettle electrode 5 form a sealed cavity. It includes an activation reaction kettle housing 2; it also includes a protection coil 3 for protecting pipelines.

[0048] The activation reaction kettle electrode drive unit is located above the activation reaction kettle electrode 5, and the liquid activation pool 8 is located below the activation reaction kettle electrode 5. Such a positional relationship will not corrode the activation reaction kettle electrode plate and is beneficial to the activation of raw material A.

[0049] The material of the liquid activation pool 8 is made of polytetrafluoroethylene. The gas inlet 6, the exhaust port 7, the liquid discharge port 9, and the liquid inlet port 10 are tower heads made of food-grade PP material and are fastened to the liquid activation pool 8 by threads. The activation reaction kettle electrode drive board unit includes an activation reaction kettle electrode drive board 4. The activation reaction kettle electrode drive board 4, the activation reaction kettle electrode 5, and the liquid activation pool 8 are fastened together by screws. The activation reaction kettle housing 2 covers the activation reaction kettle electrode drive unit, the activation reaction kettle electrode 5, and the liquid activation pool 8. There is a cooling fan 1 on one side of the activation reaction kettle housing 2, and cooling holes are provided on the activation reaction kettle housing 2 opposite to the fan and on the other two sides. During the working process of the activation reaction kettle 13, the fan keeps working to ensure sufficient heat dissipation during the working process of the activation reaction kettle 13.

[0050] The liquid discharge port 9 is placed at the bottom to fully drain the liquid without leaving any residue.

[0051] Working principle and process: During liquid feeding, liquid of raw material A enters from the liquid inlet 10, the gas inlet 6 and the liquid discharge port 9 are closed, and the exhaust port 7 is opened. The liquid can enter the inverted pyramid-shaped liquid activation tank 8 at the bottom. Then, the activation reactor electrode drive plate unit drives the activation reactor electrode 5 to discharge high voltage for activation. After activation is completed, the gas 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 gas inlet 6 through a silica gel tube to blow air into the inverted pyramid-shaped liquid activation tank 8 and discharge the liquid through the liquid discharge port 9. The raw material A solution is injected into bottle C after being activated in the activation reactor 13, and the injection duration is set to 30 seconds. During the injection of the activated A liquid, the stirring device 37 is simultaneously commanded to work, the raw material B rotating motor 35 drives the raw material B cockpit to reset. After the injection of the activated A liquid into bottle C is completed, the raw material C rotating motor 36 is commanded to rotate to the titration position, and the lifting motor 33 drives the lead screw to control the moving platform to descend and stop above bottle C. At this time, the raw material B burette 32 is directly opposite the mouth of bottle C, and the program commands the lifting motor 33 to press down the push rod of the raw material B burette 32 to drop the B liquid into bottle C.

[0052] As Figure 3 , Figure 4 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 floor of the storage bin, and both the raw material A discharging motor 15 and the material shortage detection sensor 16 are fixed with screws.

[0053] It includes a raw material A feeding bin 31, a raw material A discharging motor 15, an A bottle feeding dial 14, a bottle dialing rotating shaft 20, and an A bottle 18. The container filled with raw material A is simply referred to as the A bottle 18.

[0054] The raw material A feeding bin 31 is used to cache raw material A. Raw material A is contained in the A bottle 18. After the raw material A is extracted, the empty A bottle 18 will be automatically discarded into the waste bin 29 before the next preparation. The waste bin 29 is a device for collecting and storing the empty A bottles 18 after extracting the A liquid.

[0055] The raw material A discharging motor 15 is used to drive the feeding of the A bottle 18 and the discarding of the A bottle 18.

[0056] The A bottle feeding dial 14 is integrated on the raw material A feeding bin 31 and is used for the alignment of discarding and feeding of the A bottle 18.

[0057] The feeding device for raw material A includes a feeding bin 31 for raw material A. The feeding bin 31 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, that is, the activation reaction kettle 13, is arranged at one end of the feeding position of the feeding bin 31 for raw material A. The feeding bin 31 for raw material A is provided with a sheet metal base and a light-shielding cover 11. The sheet metal base is pasted with a polytetrafluoroethylene sliding sheet to facilitate the downward sliding of the A bottle 18 during the feeding process. The sheet metal base can also be made of other relatively slippery materials, not limited to pasting polytetrafluoroethylene. The light-shielding cover 11 and the base are connected by screws. The light-shielding cover 11 can be opened during feeding and closed after feeding. The function of the light-shielding cover 11 is to prevent raw material A from being exposed to light and ensure the quality of raw material A. The raw material A discharging motor 15, the A bottle feeding dial 14 and the bottle dialing rotating shaft 20 are connected by screws. The raw material A discharging motor 15 drives the A bottle feeding dial 14 and the bottle dialing rotating shaft 20 to rotate. There are 6 evenly distributed grooves on the bottle dialing rotating shaft 20, and the radian of each groove corresponds to the radian of the body of the A bottle 18. The rotation of the bottle dialing rotating shaft 20 drives the rotation of the A bottle 18. The A bottle feeding dial 14 is provided with 6 evenly distributed holes, which correspond one by one to the 6 grooves driving the A bottle feeding dial 14. That is, when the raw material A discharging motor 15 rotates the A bottle feeding dial 14 and the bottle dialing rotating shaft 20 by 60 degrees, the A bottle feeding dial 14 rotates from one hole to the position of the adjacent hole, and the bottle dialing rotating shaft 20 rotates from the position where one groove corresponds to the feeding position of the A bottle 18 to the position where the next groove corresponds to the feeding position of the A bottle 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 rotating shaft 20. A fixed angle of 60 degrees passes through the holes of the A bottle feeding dial 14, and the dial position sensor 19 senses whether it has rotated to the adjacent hole of the A bottle feeding dial 14. 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 19 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 14. Because the raw material A discharging motor 15 rotates the A bottle feeding dial 14 and the bottle dialing rotating shaft 20 at the same time, once the raw material A discharging motor 15 rotates to an adjacent hole position, the bottle dialing rotating shaft 20 will bring the A bottle 18 to the feeding position. The material shortage detection sensor 16 can be an optoelectronic sensor or a gravity sensor. After detecting the A bottle 18, the raw material A discharging motor 15 drives the A bottle feeding dial 14 and the bottle dialing rotating shaft 20 to rotate a fixed angle to a fixed position, and the bottle dialing rotating shaft 20 will bring the A bottle 18 to the feeding position, that is, the position for extracting raw material A.

[0058] The A bottles 18 slide out one by one from the feeding bin 31 for raw material A for bottle feeding. Raw material A is sealed in a vial with a smooth bottom by an aluminum-plastic cap, that is, the A bottle 18.

[0059] It also includes a moving platform. The raw material A feeding bin 31 is arranged on a moving platform, and the moving platform is driven to lift by a lifting motor 33. When sucking raw material A, the platform lifting motor 33 drives the raw material A feeding bin 31 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 raw material A feeding bin 31 rises to the fixed position, the liquid-taking needle assembly 12 of raw material A pierces into the A bottle 18.

[0060] 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 the extracted material to enter the activation reaction kettle 13 downward. The activation reaction kettle 13 is placed in the middle position of the tooth whitening gel preparation machine, which is also convenient for the activated liquid to smoothly enter the C raw material bottle and prevent backflow.

[0061] The raw material A feeding bin 31 is arranged on a moving platform, and the moving platform is driven to lift by a lifting motor 33.

[0062] As shown in Figures 1 and 2, the lifting motor 33 is a stepping motor, located directly below the moving platform, fixed to the core frame by screws, connected to the moving platform through a coupling and a lead screw. The moving platform integrates components such as the raw material A feeding bin 31, the raw material B burette 32, and the raw material A discharging motor 15. Each component is fixedly connected to the moving platform through sheet metal fixing parts and screws. The whole module presents an up-and-down structure. The motor controls the lifting operation of the entire lifting platform through the coupling and the lead screw, and indirectly controls the up-and-down movement of the raw material A feeding bin 31 and the raw material B burette 32. The working procedures of the lifting motor 33 and the raw material A feeding bin 31 are set as follows: A smooth polytetrafluoroethylene patch is pasted on the bottom of the raw material A feeding bin 31. After loading the raw material A bottle 18, the raw material A bottle 18 slides into the groove of the bottle-pushing rotating shaft 20 by its own weight. The sensor recognizes the raw material A bottle 18, and the program commands the bottle-pushing rotating shaft 20 to rotate the A bottle 18 to the feeding position. The lifting motor 33 drives the lead screw to control the entire lifting platform to rise, so that the raw material A feeding bin 31 containing the A bottle 18 rises, while the liquid-taking needle assembly 12 of raw material A does not move, so that the air needle bent needle tip 26 and the liquid needle straight needle tip 25 of the liquid-taking needle assembly 12 of raw material A pierce into the A bottle 18. The air needle bent needle tip 26 is connected to a diaphragm pump through a hose, and starts to blow air into the closed A bottle 18. The liquid needle straight needle tip 25 pierces to the bottom of the A bottle 18 and is connected to the activation reaction device through a hose, so that raw material A enters the activation reaction device through the liquid needle straight needle tip 25 and the pipeline. The design of using a double-needle (air and liquid) piercing and pressurized extraction for sucking 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 can be filtered to ensure the cleanliness of the gas source. The solution can be completely extracted without inverting the bottle. 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 13 along the direction of the pressure pipeline.

[0063] The activation reactor 13 is on the exclusive platform on the right side of the lifting platform and is connected to the entire movement core integrated platform through sheet metal and screws. The waste bin 29 is under the raw material A discharging motor 15. When the raw material A passes through the raw material A discharging motor 15, the A bottle 18 can fall into the waste bin 29 by its own weight. The waste bin 29 is manually pluggable. After the waste bin 29 is filled and the lifting door 30 descends, the waste bin 29 can be taken out to pour out the used empty raw material A bottles. The lifting door 30 is fixed to the outermost side of the movement core assembly through sheet metal and screws, and the lifting of the lifting door 30 is controlled by the lifting door 30 motor, lead screw and slide rail. The raw material A feeding bin 31, the raw material B burette 32, the lifting motor 33, the valve group 34, and the raw material A discharging motor 15 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 33 and the lead screw. The container of raw material B, that is, the B bottle, is located below the movement platform. The container of raw material B is driven by a robotic arm to rotate to the position where the raw material B burette 32 extracts raw material B or the storage position of the container of raw material B; the container lid removing device of the container of raw material B also has 1 motor and a robotic arm. The robotic arm is connected to the container lid removing device of the container of raw material B, and the opening or closing of the container lid of the container of raw material B is controlled by the said removing device.

[0064] As Figure 5 shown, the liquid extraction needle assembly 12 for raw material A includes a gas needle bent needle head 26, a liquid needle straight needle head 25, a needle holder 27, a Luer connector 28, and support three 22, support two 23, and support 24.

[0065] The liquid extraction needle assembly 12 for raw material A includes three layers of supports for adjusting the positions of the gas needle bent needle head 26 and the liquid needle straight needle head 25; the support 24 for fixing the gas needle bent needle head 26 and the liquid needle straight needle head 25 is used to adjust the positions of the gas needle bent needle head 26 and the liquid needle straight needle head 25 in the left-right direction; the middle support two 23 is used to adjust the positions of the gas needle bent needle head 26 and the liquid needle straight needle head 25 in the front-back direction; the outermost support three 22 is used to adjust the positions of the gas needle bent needle head 26 and the liquid needle straight needle head 25 in the up-down direction, that is, the depth at which the liquid needle straight needle head 25 inserts into the A bottle 18, to ensure that the liquid in the raw material A bottle 18 is fully discharged.

[0066] The setting of the support three 22 adjusts the vertical position of the entire liquid extraction module through the lengthened fixing screw holes to ensure that the liquid in the raw material A bottle 18 is fully discharged. The needle holder 27 fixes the gas needle bent needle head 26 and the liquid needle straight needle head 25 to the support 24 through 4 screws, and the liquid extraction needle assembly 12 for raw material A is fixed to the sheet metal part of the raw material A feeding unit.

[0067] The design of using a gas needle bent needle 26 and a liquid needle straight needle 25 to pierce and extract under pressure for extracting liquid A can ensure that the liquid A is in a fully enclosed environment before extraction. During the extraction process, the pressurized gas passes through a filter to ensure the cleanliness of the gas source. The solution in the bottle can be completely extracted without inverting the bottle body.

[0068] Working principle

[0069] The low-concentration hydrogen peroxide liquid (liquid A) solution is input into the activation reaction kettle 13 through the opening and closing of the gas-liquid valve for plasma activation reaction to enhance its activity and redox ability. Through the action of the stirring device 37, the activated hydrogen peroxide liquid, powder (in bottle C), and another raw material (liquid B) are mixed. After stirring and mixing evenly, a gel is prepared.

[0070] The stirring device 37 includes a raw material C rotating motor 36, a bottle C, a robotic arm, a raw material C cockpit, a magnetic stirrer, and a rotating head with a permanent magnet. Bottle C represents the container for holding raw material C, which can be bottle-shaped or other shaped containers.

[0071] The base of the stirring device 37 has two magnetic poles respectively. The motor drives the base to rotate, and the magnetic poles of the base attract the magnetic stirrer in bottle C to rotate.

[0072] The motor of the stirring device 37 is connected to the rotating head, and a permanent magnet is arranged inside the rotating head. The stirrer is arranged in bottle C.

[0073] The inside of the stirrer is a permanent magnet or magnetic material, and the outer layer is wrapped with polytetrafluoroethylene material, with a smooth or rough coating.

[0074] The position of the permanent magnet in the rotating head corresponds to that of the stirrer. If the shape of the stirrer is a long pill shape, the two permanent magnets are symmetrically arranged at 180 degrees. If the stirrer is cross-shaped, one permanent magnet can be arranged every 90 degrees in the rotating head, with a total of 4 arranged. In short, the permanent magnet in the rotating head drives the stirrer to rotate by magnetic attraction.

[0075] It also includes a raw material C feeding device, which includes a raw material C rotating motor 36, an infrared photoelectric sensor, a lifting door 30, and a raw material C cockpit.

[0076] The raw material C rotating motor 36 is an industrial-grade standard servo motor, 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: On the upper computer operation interface, click the "Load C" button on the right, the lifting door 30 descends to the preset position, and the raw material C cockpit is exposed (initial position). The RFID module is used to mark the code for tracing the raw material C bottle. Bring the C bottle containing raw material C close to the RFID module for identification to detect the C bottle information and expiration date, and upload the detection and verification information to the cloud server. After passing the verification, put the C bottle into the raw material C cockpit. When the infrared sensor detects the presence of the C bottle, the next program can be carried out. Click to close the hatch 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.

[0077] The raw material C rotating motor 36 drives the raw material C cockpit to automatically open in place at the outlet. After putting the C bottle in, it rotates to the stirring position and the titration position, and automatically clamps the C bottle after leaving the outlet.

[0078] The raw material C rotating motor 36 is a power-providing mechanism. By controlling the raw material C cockpit with the raw material C rotating motor 36, the device can fix or release the C bottle. By controlling the raw material C cockpit with the raw material C rotating motor 36, the C bottle can be swung to the outlet position of the C bottle, or the stirring position of the C bottle, or the titration position of the C bottle.

[0079] 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 outlet position of the C bottle. The raw material C cockpit on the robotic arm hits the limit stop block, and the clamping force of the cockpit on the bottle becomes smaller, making the bottle in a relaxed and removable state. After the tooth whitening gel is prepared, the lifting door 30 descends, and the C bottle containing the tooth whitening gel can be taken out.

[0080] The liquid device vacancy detection sensor is used to detect the presence of the C bottle, and the swing position sensor is used to detect the position of the C bottle, so as to realize the automatic control of the C bottle for stirring. The principle of the sensor is not limited, and the sensors of the existing technology can be used to achieve it. When the C bottle is injected with the activated aqueous solution of raw material A activated from the activation reaction kettle 13 at the stirring position, after the activated water and raw material C are initially stirred, the C bottle is rotated to the titration position to drop the raw material B solution, then rotated back to the stirring position to continue stirring, and finally the prepared tooth whitening gel is taken out at the outlet position for use.

[0081] It also includes a raw material B titration device, which consists of a push rod stroke sensor, an electric push rod, a moving platform, and a raw material B titrator 32. 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, thus realizing automatic control. The principle of the sensor is not limited, and the sensors of existing technologies can be used to achieve this. 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 moving platform for lifting and lowering, or it can share a moving platform with the raw material A feeding bin 31.

[0082] It also includes a raw material B feeding device, which consists of a raw material B rotating motor 35, a raw material B loading button, a robotic arm cockpit, and a B bottle, where the B bottle is the container filled with raw material B. The raw material B rotating motor 35 holds the B bottle through the robotic arm cockpit. The raw material B rotating motor 35 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 settings. It also includes 1 motor, namely the raw material B cockpit cover motor, and a robotic arm. The robotic arm is connected to the container cover of raw material B, and the opening or closing of the container cover filled with raw material B is controlled by controlling the lifting or lowering of the robotic arm.

[0083] The raw material B rotating motor 35 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 by sheet metal and screws to cooperate with the operation of the raw material B loading program. The complete working process of loading raw material B is as follows: click the B loading button, the lifting motor 33 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 35 rotates clockwise by 90° 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 35. Click the raw material B loading switch again, the raw material B rotating motor 35 rotates counterclockwise by 90° to the B bottle storage position, and the lifting motor 33 descends to the preset position. At this time, the B feeding is completed.

[0084] The raw material B rotating motor 35 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 32. The raw material B titrator 32 sucks the B solution, then moves the B bottle back to the storage position, covers the bottle cap. The raw material C rotating motor 36 swings the C bottle filled with activated water and C powder that has been preliminarily stirred to the titration position below the raw material B titrator 32, drops the B solution. 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 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.

[0085] The overall composition of a tooth whitening gel preparation machine includes a touch display screen, which is located in the upper front of the device, convenient for operation, used for human-machine interaction, starting the preparation of tooth whitening gel and displaying the preparation status, showing the preparation time, and can also be used to test the preparation machine. The outer shell is the protective shell of the tooth whitening gel preparation machine, used to protect the internal components of the device, with a beautiful appearance, convenient for operation and handling. The handle and drag handle are convenient for handling and moving the tooth whitening gel preparation machine. The operation indicator light is used to display the operation status of the device.

[0086] The upper computer microcomputer is a platform for human-machine interaction and server interaction. At the same time, corresponding action instructions need to be sent to the lower computer electric control for execution. The lower computer electric control is mainly for the control of the preparation logic program and signal detection and judgment.

[0087] The movement platform of the movement mechanism assembly includes all actuators, motors, and sensors assembled together, enabling the tooth whitening gel preparation machine to automatically prepare tooth whitening gel. The actuator includes a liquid-gas valve and a robotic arm. The power distribution control box is located below the movement mechanism assembly to supply power to each component of the device.

[0088] The valve group 34 is a valve control module used to control the on-off of the gas source and switch the gas path and liquid path.

[0089] The valve group 34 is on the upper part and the back of the device. The valve group 34 is a general term for all valves. In this application, when it is said to open or close the valve group 34, or when the valve group 34 is involved somewhere, it refers to opening or closing the corresponding valve of the device or equipment in this step, not all valves.

[0090] The traditional liquid path and gas path both adopt the solenoid valve scheme. The solenoid valve has a short service life, a complex structure and is prone to problems. When it is opened for a long time, it will heat up or burn out.

[0091] In this application, the valve group 34 adopts the servo steering gear method. Each valve is controlled in series through bus communication, and the circuit is simple and easy to maintain. At the same time, the flow rate can also be controlled by controlling the angle of the valve. Since the mechanical rotation plus control angle servo steering gear scheme is adopted, the valve switch can maintain a state for a long time, and there is no situation of overheating or burning out even when powered on for a long time. The servo steering gear is installed on the bracket to control the opening and closing of the valve. The mechanical valve is completely isolated from the servo motor to prevent the liquid from corroding the circuit components.

[0092] 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 make the raw material A in the A bottle 18 enter the activation reaction kettle 13. After activation, the activation water is injected into the C bottle through the injection needle assembly under the control of the exhaust valve assembly of the activation reaction kettle 13, the C bottle injection liquid valve assembly, and the C bottle injection gas valve assembly. Example 2

[0093] A tooth whitening gel preparation system includes the tooth whitening gel preparation machine described in any of the above embodiments, and further includes a cloud server for managing the operating status of the device, as well as the preparation data and data storage.

[0094] The gel prepared by the device of the present application can be used in scenarios such as dental clinics, oral hospitals, and medical aesthetic institutions to assist doctors in performing cold light bleaching reactions on yellow teeth, sensitive teeth, tea-stained teeth, tobacco-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 like acne and gingivitis. Example 3

[0095] A tooth whitening gel preparation method, which is used for the tooth whitening gel preparation machine described in any of the above embodiments. Inject raw material A with a concentration of 2.5% - 6% into the activation reaction kettle for activation. Raw material A is a hydrogen peroxide solution; after activation, inject the activated solution into raw material C. Raw material C is carbomer; before the second stirring, drop in raw material B. Raw material B is a neutralizing agent, and then stir well to make the tooth whitening gel; during a single preparation process, the volume ratio of the hydrogen peroxide solution to the neutralizing agent is 15:1. By touching the display screen of a tooth whitening gel preparation machine and clicking the automatic activation button, the program controls the lifting door to start descending. The raw material C rotating motor 36 controls the robotic arm to work to the outlet. After the action is completed, it returns a command to the touch display screen, indicating that it can be loaded. After loading is completed, click the touch display screen to confirm the placement of the C bottle, and at the same time, the device detects whether the C bottle is placed. The C bottle is a container filled with raw material C. After detecting successful placement, record the production date and set the expiration date. Control the lifting door 30 to start rising and close the hatch. Enter the password to start sending commands to start the preparation.

[0096] As Figure 6 shown, at the beginning of the preparation, first drive the A bottle feeding dial 14 of the raw material A discharging motor 15 to rotate, and transport the raw material A in the raw material A upper material bin 31 to the designated position, that is, the raw material A extraction and feeding position. Discard the extracted waste A bottle 18 into the A bottle waste bin 29. The A bottle waste bin 29 collects the containers from which 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, pressurize to extract raw material A into the activation reaction kettle 13. Wait until the liquid is completely drawn out and then start the activation reaction kettle 13 for activation work, and the lifting motor 33 starts to descend. At this time, the raw material C rotating motor 36 transports the C bottle to the filling position through the robotic arm. The filling position and the stirring position are the same position. The raw material B rotating motor 35 transports the B bottle to the titration position through the robotic arm, and the raw material B titrator 32 sucks raw material B and waits for titration. The B bottle is a container filled with raw material B.

[0097] After the activation of the activation reactor 13 is completed, open the valve to pressurize and fill the activated raw material tank into the container of raw material C, that is, the C bottle, and the stirring device 37 starts magnetic stirring. After the filling is completed, the lifting motor 33 starts to drive the raw material B burette 32 to rise, the raw material B rotating motor 35 runs the B bottle to the storage position through the robotic arm, the raw material C rotating motor 36 runs the C bottle to the titration position through the robotic arm, and the raw material B burette 32 titrates the aspirated raw material B into the C bottle after the filling is completed. When the titration is completed, the raw material C rotating motor 36 runs the C bottle to the stirring position through the robotic arm, and continues magnetic stirring to complete the preparation.

[0098] After the preparation is completed, the touch display screen shows that the countdown ends, indicating completion. Click the open hatch button to control the lifting door 30 to start descending, and the raw material C rotating motor 36 transports the C bottle to the exit position through the robotic arm. Then the finished product can be taken out.

[0099] Raw material A, raw material B, and raw material C respectively represent a raw material or a mixture of several raw materials.

[0100] Raw material A is a hydrogen peroxide solution with a concentration of 2.5%-6%, and the optimal one is 6%. It is filled in a vial sealed with a rubber stopper, that is, the A bottle 18, and the volume of the A bottle 18 is 5 ml. Raw material B is a neutralizer, and the main component is a sodium hydroxide solution with a concentration of 10%. It is filled in a vial sealed with a rubber stopper, that is, the B bottle, and the volume of the B bottle is 8 ml. Raw material C is carbomer, with a mass of 0.02-0.08 g, and the optimal one for a single preparation is 0.04 g. Raw material C and the stir bar are placed in a vial, and the C bottle is a vial. In the tooth whitening gel preparation machine of the present application, the distance that the motor drives the lifting platform has good repeatability. There will be fixed liquid residues in the A bottle 18. During a single preparation process, 3 ml of raw material A is used, about 0.2 ml of A liquid remains, about 0.2 ml of raw material B, and 0.04 g of raw material C. An activation time of 5-10 min is required, and 7 or 8 min is optimal. At this time, the performance of the activated water reaches a stable state. The volume ratio of the hydrogen peroxide solution to the neutralizer is 15:1. This ratio has just the right consistency, can adhere to the teeth, and has a moderate pH value. The stirring time is generally 5-10 minutes.

[0101] Ratio 1: 3.2 ml of hydrogen peroxide solution with a concentration of 2.5%, 0.2 ml of neutralizer with the main component being 10% sodium hydroxide solution, and 0.02 g of carbomer.

[0102] Ratio 2: 3.2 ml of hydrogen peroxide solution with a concentration of 3%, 0.2 ml of neutralizer with the main component being 10% sodium hydroxide solution, and 0.04 g of carbomer.

[0103] Ratio 3: 3.2 ml of hydrogen peroxide solution with a concentration of 6%, 0.2 ml of neutralizer with the main component being 10% sodium hydroxide solution, and 0.08 g of carbomer.

[0104] The tooth whitening gels prepared from the above three formulations through the preparation mechanism of the tooth whitening gel of the present application can be directly coated on the tooth surface, and the effect differences are not significant. The effect of formulation 3 is the best, without the need for a gum protector, having a definite tooth whitening effect, and at the same time being able to greatly reduce the risks of common allergies and post-whitening soreness caused by high-concentration hydrogen peroxide gels.

[0105] Clinical results show that the whitening gels and whitening liquids prepared using the device of the present invention are non-toxic, non-irritating, and odorless. After whitening, there is no residual gel after rinsing, and they have a good tooth whitening effect.

[0106] The tooth whitening effect can be adjusted by adjusting the concentration of the hydrogen peroxide solution in raw material A, the activation time of activation reactor 13, the thickness of the gel coated on the teeth, and the time for the gel to act on tooth whitening.

[0107] The 40 subjects participating in the clinical trial had yellow teeth with common exogenous staining. They were divided into 2 groups for testing, with 20 individuals in each group. The experimental group used the tooth whitening gel prepared from formulation 2 and this device. The control group used 3 ml of ultrapure water to replace the activated raw material A, with the neutralizing agent being 0.2 ml of 10% sodium hydroxide solution and 0.04 g of carbomer, and the gel was prepared manually.

[0108] 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 none used a desensitizer after whitening.

[0109] The whitening effect was mainly evaluated and analyzed using the VITA Bleachedguide 3D-Master colorimetric plate, which is a commonly used visual effect analysis method in clinical practice.

[0110] The color of the teeth is determined by three values: brightness, color saturation, and color value through color comparison with the colorimetric plate (here, the Vita colorimetric plate is used as an example). The M column is the intermediate color, the L column is more yellow, and the R column is more red. First, compare the brightness horizontally. Among the 5 groups of 1, 2, 3, 4, and 5, find the group with the highest brightness from dark to light. Second, compare the saturation vertically and find the one with the best saturation. Then compare the color value horizontally.

[0111] The tooth whitening gel prepared by this device has an excellent whitening effect. The color difference ΔE of the teeth before and after whitening can be 3 - 8 color scales, and none of the participating subjects had a sense of soreness after the operation.

[0112] According to the same gel coating and color comparison methods, the color difference ΔE of the teeth before and after whitening in the control group increased by nearly 0 color scales.

[0113] The experimental results were statistically analyzed using statistical analysis software. The results were expressed as mean ± standard deviation, and a normal distribution test was performed. An independent samples t-test or a 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 color difference ΔE of the teeth in the sample group before and after whitening was 3.90 ± 1.14. The color difference ΔE of the teeth in the control group before and after whitening was 0.00 ± 0.00. There was a very significant difference in the color level between the sample group after using the product 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 device compared with the control group.
