Description
A tooth whitening gel preparation machine and preparation method TECHNICAL FIELD
[0001] The present application relates to devices for dentistry and dental hygiene, in particular to a tooth whitening gel preparation machine and tooth whitening gel preparation method. BACKGROUND
[0002] Cold light whitening technology is a tooth whitening method that uses specific wavelengths of cold light to irradiate teeth, accelerating the penetration and reaction of whitening agents, thereby quickly removing surface and deep pigment deposition on teeth. It has a significant effect and is relatively easy to operate, and is favored by many people who pursue tooth whitening.
[0003] The main component of the whitening agent used in cold light whitening technology is hydrogen peroxide (usually at a concentration of 17%-35%), and may also contain auxiliary components such as silicon dioxide. Hydrogen peroxide is a strong oxidizing agent that can rapidly undergo redox reactions under the irradiation of cold light, releasing free oxygen. These free oxygen can penetrate the enamel of the teeth and combine with the pigment molecules on the surface of the teeth, breaking them down into colorless small molecules, thereby achieving the effect of whitening.
[0004] Due to the improvement of the whitening agent formula and the enhancement of the penetration ability, the bright teeth whitening technology can provide more lasting whitening effect, reducing the need for patients to frequently receive whitening treatment. Compared with traditional cold light whitening technology, bright teeth whitening technology significantly reduces the risk of postoperative sensitivity and tooth damage, improving the overall comfort of patients. Although the bright teeth whitening technology has been optimized in many ways, it still cannot completely avoid some potential problems in traditional tooth whitening technology. In particular, the use of high-concentration hydrogen peroxide, even if it is reduced in the bright teeth whitening technology, high concentration can still cause some damage to the teeth.
[0005] While low-concentration hydrogen peroxide causes less damage to the teeth, its whitening effect is often not obvious and lasts for a short time. This dilemma of high-concentration damage and low-concentration poor effect is a technical problem that needs to be solved.
[0006] The existing method of activating hydrogen peroxide solution by low-temperature plasma is to inject a certain flow of high-voltage discharge gas into the hydrogen peroxide solution. Due to the existence of a certain transmission distance and time, and the short survival time of active ingredients, a large amount of active ingredients are lost during this process, resulting in low absorption efficiency and long activation time. This method continuously produces long-lived ozone and nitrogen oxides, which diffuse in the room, causing indoor air pollution and harm to the health of indoor personnel. SUMMARY
[0007] The main purpose of the present application is to overcome the defects of the prior art, and provide an activation reactor comprising an activation reactor, the activation reactor comprising an activation reactor electrode driving plate unit, an activation reactor electrode, an inlet and outlet liquid unit, an inlet and outlet gas unit, and a liquid activation tank; the activation reactor electrode driving plate unit is located at the upper part of the activation reactor electrode, and the liquid activation tank is located at the lower part of the activation reactor electrode; the liquid activation tank and the activation reactor electrode form a sealed cavity.
[0008] Unlike the prior art, the activation reactor electrode and the raw material A solution, such as hydrogen peroxide solution, are sealed in a cavity, and the distance between the electrode and the raw material A solution is very short, only 5-10 mm. The active ingredients generated by electrode discharge 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 needs a longer time, some as long as two or three minutes, and the use feature of the tooth whitening gel machine of the present application is to prepare tooth whitening gel machine on site in dental clinics or hospitals and the like, and to provide users with on-site use, so the preparation time is particularly important, and short preparation time shortens the waiting time of users, and more users can be received within the effective time.

The dial position sensor is arranged above the A bottle feeding dial to detect the rotation angle of the A bottle feeding dial. When the A bottle feeding dial rotates to the predetermined angle, the bottle pushing shaft 20 and the A bottle feeding dial stop rotating, so as to ensure that the A bottle sliding to the groove of the bottle pushing shaft 20 by gravity is rotated to the feeding position below the raw material A liquid taking needle assembly.

Detailed Implementation
[0044] The following describes the definitions, connection methods, working principles, and processes of the various unit modules of this invention, including various details of the embodiments of this invention to aid understanding. These 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 this invention.
[0045] The modules, units, mechanisms, and devices involved in this patent application are not limited to specific software or hardware environments; they possess a high degree of abstraction and flexibility. Whether it is a software module that relies on software programs to achieve specific functions, or a hardware unit built based on physical circuits, mechanical structures, etc., all fall within the scope of this patent application. The description of its functions and logic focuses on the overall design concept, operational process, and the effects and goals that can be achieved, rather than being limited to specific software or hardware implementation forms. Example 1
[0046] This invention provides a teeth whitening gel preparation machine, including an activation reaction vessel. The activation reaction vessel includes an activation reaction vessel electrode drive plate unit, an activation reaction vessel electrode unit, a liquid inlet / outlet unit, a gas inlet / outlet unit, and a liquid activation pool. The activation reaction vessel electrode drive plate unit is located at the upper part of the activation reaction vessel electrode unit, and the liquid activation pool is located at the lower part of the activation reaction vessel electrode unit. The liquid activation pool and the activation reaction vessel electrode form a sealed cavity.
[0047] As shown in Figure 1-2, the activation reactor electrode drive plate unit includes an activation reactor electrode drive plate 4, a liquid inlet / outlet unit including a drain port 9 and a liquid inlet 10, a gas inlet / outlet unit including a gas inlet 6 and a gas outlet 7, and a liquid activation tank 8. The liquid activation tank 8 and the activation reactor electrode 5 form a sealed cavity. It also includes an activation reactor shell 2 and a protective coil 3 for protecting the pipelines.
[0048] The electrode drive unit 4 of the activation reactor is located above the electrode 5 of the activation reactor, and the liquid activation pool 8 is located below the electrode 5 of the activation reactor. This positional relationship will not corrode the electrode plate and is beneficial to the activation of raw material A.
[0049] The liquid activation tank is made of polytetrafluoroethylene (PTFE). The air inlet 6, exhaust outlet 7, liquid outlet 9, and liquid inlet 10 are pagoda-shaped connectors made of food-grade PP material, which are threaded onto the liquid activation tank 8. The activation reactor electrode drive plate unit includes the activation reactor electrode drive plate, and the activation reactor electrodes and liquid activation tank are fastened together with screws. The activation reactor shell covers the activation reactor electrode drive unit, activation reactor electrodes, and liquid activation tank. A cooling fan is located on one side of the activation reactor shell, and ventilation holes are provided on the opposite side of the fan and the other two sides of the shell. The fan operates continuously during the activation reactor's operation to ensure sufficient heat dissipation.
[0050] Drainage port 9 is placed at the bottom to ensure complete drainage and prevent liquid residue.
[0051] Working principle and process: During liquid loading, raw material liquid A enters through inlet 10, air inlet 6 and drain 9 are closed, and exhaust 7 is opened, allowing the liquid to enter the inverted pyramid-shaped liquid activation tank 8 at the bottom. Then, the electrode drive plate unit of the activation reactor drives the electrode drive plate of the activation reactor to discharge at high voltage, activating the liquid. After activation, air inlet 6 and drain 9 are opened, and exhaust 7 and inlet 10 are closed. An air pump is connected to air inlet 6 through a silicone tube, blowing air into the inverted pyramid-shaped liquid activation tank 8, and draining the liquid out through drain 9. After the raw material solution A is activated in the activation reactor, it is injected into bottle C. The injection time is set to 30 seconds. During the injection of activated solution A, the stirring device 37 is simultaneously instructed to work, and the raw material B rotary motor 35 drives the raw material B chamber to reset. After the activated solution A is injected into bottle C, the raw material C rotary motor 36 is instructed to rotate to the titration position. The lifting motor drives the lead screw to control the motion platform to fall to a stop above bottle C. At this time, the raw material B titrator 32 is facing the mouth of bottle C. The program instructs the lifting motor to press down the push rod of the raw material B titrator 32 to drip solution B into bottle C.
[0052] As shown in Figures 3 and 4, it also includes a raw material A feeding device, which is used to supply raw material A to the activation reactor.
[0053] It includes a raw material A feeding hopper 31, a raw material A discharging motor 15, an A-bottle feeding dial 14, a bottle-discharging shaft 20, and an A-bottle 18. The container containing raw material A is referred to as A-bottle.
[0054] Raw material A feeding hopper 31 is used to buffer raw material A. Raw material A is stored in bottle A. After raw material A is extracted, the empty bottle A is automatically discarded into waste hopper 29 before the next preparation. Waste hopper 29 is a device for collecting and storing empty bottles A after extracting liquid A.
[0055] The raw material A discharge motor 15 is used to drive the feeding of bottle A and the discarding of bottle A.
[0056] Bottle A feeding dial 14 is integrated on the raw material A feeding hopper 31 and is used for the alignment of discarded and feeding bottles of Bottle A.
[0057] The raw material A feeding device includes a raw material A feeding bin 31, which is a rectangular cavity with a smooth bottom surface. It is used to buffer containers containing raw material A and is inclined, with the feeding position at the lowest point. The activation reaction device is located at one end of the raw material A feeding bin at the feeding position. The raw material A feeding bin 31 is equipped with a sheet metal base and a light-shielding cover. The sheet metal base is fitted with a polytetrafluoroethylene (PTFE) sliding plate to facilitate the downward sliding of the A bottle during feeding. The sheet metal base can also be made of other relatively smooth materials, not limited to PTFE. The light-shielding cover and the base are connected by screws. The light-shielding cover can be opened during feeding and closed after feeding. The raw material A discharging motor 15, the A bottle feeding dial 14, and the bottle-discharging shaft 20 are connected by screws. The raw material A discharging motor 15 drives the A bottle feeding dial 14 and the bottle-discharging shaft 20 to rotate. The bottle-dispensing shaft 20 has six evenly distributed grooves, each corresponding to the curvature of bottle A. Rotation of the bottle-dispensing shaft 20 drives bottle A to rotate. The bottle A feeding disc 14 has six evenly distributed holes, each corresponding to one of the six grooves driving the bottle A feeding disc 14. That is, when the raw material A discharge motor 15 rotates the bottle A feeding disc 14 and the bottle-dispensing shaft 20 rotates 60 degrees, the bottle A feeding disc 14 moves from one hole to the position of the adjacent hole, and the bottle-dispensing shaft 20 moves from one groove corresponding to the feeding position of bottle A to the next groove corresponding to the feeding position of bottle A. A bottle A feeding dial 14 is equipped with a dial position sensor 19 on its upper part. The raw material A discharging motor 15 rotates the bottle A feeding dial 14 and the bottle-discharging shaft 20, passing through a hole in the bottle A feeding dial 14 at a fixed angle of 60 degrees. The dial position sensor detects whether the dial has rotated to an adjacent hole. Once it reaches the hole, it is determined that the set position has been reached, and rotation stops. The dial position sensor can be a photoelectric sensor, relying on photoelectric sensing to determine whether the dial has rotated to the set position. Because the raw material A discharging motor 15 simultaneously rotates the bottle A feeding dial 14 and the bottle-discharging shaft 20, once the raw material A discharging motor 15 rotates to an adjacent hole, the bottle-discharging shaft 20 brings the bottle A to the feeding position. The material shortage detection sensor can be a photoelectric sensor or a gravity sensor. Once bottle A is detected, the raw material A discharge motor 15 drives the bottle A feeding dial 14 and the bottle-discharging shaft 20 to rotate by a fixed angle to a fixed position. The bottle-discharging shaft 20 then brings bottle A to the feeding position, which is the position for extracting raw material A.
[0058] Bottle A is fed one by one from the raw material A feeding hopper 31. Raw material A is sealed in a smooth-bottomed vial with an aluminum-plastic cap, i.e., bottle A.
[0059] It also includes a motion platform, on which the raw material A feeding hopper is mounted. The motion platform is raised and lowered by a lifting motor. When raw material A is being drawn up, the platform lifting motor drives the raw material A feeding hopper 31 to rise to a fixed position. Position control is achieved by controlling the rotation angle of the motor through communication with the lower-level machine. After the raw material A feeding hopper rises to the fixed position, the raw material A dispensing needle assembly is inserted into bottle A.
[0060] The raw material A liquid collection needle assembly includes a curved air needle, a straight liquid needle, a needle holder, a Luer connector, and a fixed sheet metal bracket. The bracket is designed to adjust the vertical position of the entire liquid collection module, i.e., the depth to which the straight liquid needle is inserted into bottle A, ensuring complete drainage of the liquid from bottle A. The needle holder secures the air and liquid needles to the bracket with four screws. The raw material A liquid collection needle assembly is fixed to the sheet metal parts of the raw material A feeding device.
[0061] The raw material A feeding device is located at the top of the teeth whitening gel preparation machine, which facilitates the extraction and downward entry into the activation reactor 1. The activation reactor 1 is placed in the middle of the teeth whitening gel preparation machine, which also facilitates the smooth entry of the activated liquid into the raw material C bottle, preventing backflow.
[0062] The raw material A feeding hopper is set on a moving platform, which is driven to rise and fall by a lifting motor.
[0063] As shown in Figures 1 and 2, the lifting motor 33 is a stepper motor, located directly below the motion platform. It is fixed to the core frame with screws and connected to the motion platform via a coupling and a lead screw. The motion platform integrates components such as the raw material A feeding bin 31, the raw material B titrator 32, and the raw material A discharging motor 15. Each component is fixed to the motion platform via sheet metal fasteners and screws. The entire module has an upper and lower structure. The motor controls the lifting operation of the entire lifting platform through the coupling and lead screw, thereby indirectly controlling the vertical movement of the raw material A feeding bin 31 and the raw material B titrator 32. The operating procedure of the lifting motor 33 and the raw material A feeding hopper 31 is set as follows: A smooth polytetrafluoroethylene patch is attached to the bottom of the raw material A feeding hopper. After the raw material A bottle is filled, it slides down to the groove of the bottle-dispensing shaft 20 by its own weight. The sensor detects the raw material A bottle, and the program instructs the bottle-dispensing shaft 20 to rotate the A bottle to the feeding position. The lifting motor drives the lead screw to control the entire lifting platform to rise, thus raising the raw material A feeding hopper containing the A bottle. The raw material A liquid-taking needle and air needle assembly remain stationary, allowing the liquid-taking needle and air needle of the raw material A liquid-taking needle assembly to pierce the A bottle. The air needle is connected to a diaphragm pump via a hose and begins blowing air into the sealed A bottle. The liquid-taking needle pierces the bottom of the A bottle and is connected to the activation reaction device via a hose, thus allowing raw material A to enter the activation reaction device through the liquid-taking needle and pipeline. The extraction of raw material A liquid uses a double-needle piercing pressurized extraction design. This design ensures that the A liquid is in a completely sealed environment before extraction. During extraction, the pressurized gas is filtered to ensure the cleanliness of the gas source. The solution can be completely extracted without inverting the bottle. Raw material A is extracted by applying gas pressure in a closed pipeline, allowing the solution to enter the activation reactor along the pressure pipeline.
[0064] The activation reactor is located on a dedicated platform to the right of the lifting platform, connected to the entire core integration platform via sheet metal and screws. The waste bin 29 is located below the raw material A discharge motor 15. When raw material A passes the discharge motor 15, bottle A falls into the waste bin 29 by its own weight. The waste bin 29 is manually removable. When the waste bin is full, the lifting door 30 descends, allowing the waste bin 29 to be removed and the empty raw material A bottles to be emptied. The lifting door 30 is fixed to the outermost part of the core assembly via sheet metal and screws, and its raising and lowering are controlled by the lifting door 30 motor, lead screw, and slide rail. The raw material A loading bin 31, raw material B titrator 32, lifting motor 33, valve assembly 34, and raw material A discharge motor 15 are fixed to the motion platform by sheet metal and screws, forming an overall vertical structure. The lifting motor 33 and lead screw 35 drive the entire platform to move up and down. The container for raw material B, namely bottle B, is located below the motion platform. A robotic arm rotates the container containing raw material B to the position where the raw material B titrator 32 extracts raw material B or to the position where the container containing raw material B is stored. The container cap removal device for raw material B also includes a motor and a robotic arm. The robotic arm is connected to the container cap removal device for the container containing raw material B, and the cap removal device controls the opening or closing of the container cap containing raw material B.
[0065] As shown in Figure 5, the raw material A liquid collection 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 fixed sheet metal brackets 22, 23, and 24.
[0066] The raw material A liquid collection needle assembly 12 includes three layers of supports for adjusting the positions of the air needle 26 and the liquid needle 25; the support 24 for fixing the air needle 26 and the liquid needle 25 is used to adjust the left and right positions of the air needle and the liquid needle; the middle support 23 is used to adjust the front and back positions of the air needle and the liquid needle; and the outermost support 22 is used to adjust the up and down positions of the air needle and the liquid needle.
[0067] The bracket 22 is designed to adjust the vertical position of the entire liquid dispensing module by extending the fixing screw holes, ensuring that the liquid in the raw material A bottle is fully discharged. The needle holder 27 fixes the gas needle and liquid needle to the bracket 24 with four screws, and the A bottle liquid dispensing needle assembly 12 is fixed to the sheet metal part of the raw material A feeding unit.
[0068] The extraction of solution A utilizes a double-needle pressurized extraction design. This design ensures a completely sealed environment for solution A before extraction, and the pressurized gas is filtered during extraction to guarantee the cleanliness of the gas source. The solution can be completely extracted without inverting the bottle.
[0069] Working principle
[0070] A low-concentration hydrogen peroxide liquid solution (solution A) is introduced into the activation reactor via a gas-liquid valve for plasma activation, enhancing its activity and redox capabilities. The activated hydrogen peroxide liquid, powder (in bottle C), and another raw material (solution B) are then mixed using a stirring module, and the mixture is stirred until homogeneous to form a gel.
[0071] It also includes a stirring device 37, which comprises a raw material C rotary motor 36, a C bottle, a robotic arm, a raw material C chamber, a magnetic stir bar, and a rotating head with a permanent magnet. The C bottle refers to the bottle containing the raw material C, which can be bottle-shaped or other types of containers.
[0072] The stirring device 37 has two magnetic poles on its base. The motor drives the base to rotate, and the magnetic poles of the base attract the magnetic stir bar in bottle C to rotate.
[0073] The stirring device 37 has a motor connected to a rotating head, and a permanent magnet is installed inside the rotating head. The stir bar is placed inside bottle C.
[0074] The stir bar has a permanent magnet or magnetic material inside, and is wrapped with polytetrafluoroethylene material on the outside, which can be either smooth or rough.
[0075] The permanent magnets in the rotating head are positioned to correspond with the stir bar. If the stir bar is shaped like a long, thin pill, the two permanent magnets are symmetrically positioned at 180 degrees. If the stir bar is cross-shaped, the permanent magnets in the rotating head can be placed at 90-degree intervals, for a total of four. In short, the permanent magnets in the rotating head drive the stir bar to rotate using magnetic attraction.
[0076] It also includes a raw material C feeding device, which includes a raw material C rotary motor 36, an infrared photoelectric sensor, a lifting door 30, and a raw material C cabin.
[0077] The rotary motor 36 for raw material C is an industrial-grade standard servo motor, fixed to the component base platform via sheet metal. The motor and base are secured together via sheet metal to facilitate the loading and identification process of raw material C. The loading process for raw material C is as follows: On the host computer interface, click the "Load C" button on the right. The lifting door 30 descends to the preset position, exposing the raw material C compartment (initialization position). The RFID module is used for coding and traceability of the raw material C bottle. Bring the C bottle containing raw material C close to the RFID module for identification to detect the bottle information and expiration date. The detection and verification information is uploaded to the cloud server. After verification, place the C bottle into the raw material C compartment. The infrared sensor detects the presence of the C bottle, and the next procedure can proceed. Follow the prompts to close the compartment door, and the lifting door 30 rises to the preset position, completing the loading of raw material C.
[0078] The rotary motor 36 drives the raw material C chamber to automatically open at the outlet. After the raw material C bottle is placed in, it rotates to the stirring and titration positions and automatically clamps the C bottle after leaving the outlet.
[0079] The rotary motor 36 for raw material C is the power-providing mechanism. By controlling the raw material C chamber via the rotary motor 36, the equipment can fix or release the C bottle. The rotary motor 36 also controls the raw material C chamber to swing the C bottle to the outlet position, the stirring position, or the titration position.
[0080] After mixing at the stirring position, the raw material C rotary motor 36 controls the raw material C chamber to swing the C bottle to the outlet position. The raw material C chamber on the robotic arm hits the limit stop, reducing the clamping force of the chamber on the bottle, making the bottle relaxed and removable. After the teeth whitening gel is prepared, the lifting door 30 descends, allowing the removal of the C bottle containing the teeth whitening gel.
[0081] The presence of bottle C is detected by a liquid device empty detection sensor, and the position of bottle C is detected by a swing position sensor, thereby achieving automated control of the stirring of bottle C. The principle of the sensors is not limited; existing sensor technology can be used. When bottle C is in the stirring position, the activated aqueous solution of raw material A, activated from the activation reactor, is injected. After initial stirring of the activated water and raw material C, bottle C is rotated to the titration position to drip in the raw material B solution. It then rotates back to the stirring position to continue stirring, and finally, the prepared teeth whitening gel is removed from the outlet position for use.
[0082] It also includes a raw material B titration device, which comprises 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, causing the titrator push rod to rise or fall, thereby drawing solution B from bottle B and then dripping the solution B into bottle C. The push rod stroke sensor is used to detect the stroke of the electric push rod, thus achieving automated control. The principle of the sensor is not limited; existing sensor technology can be used. The raw material B titrator 32 is used to accurately set the volume of raw material B to be titrated. The raw material B titrator 32 can be equipped with a separate motion platform for lifting and lowering, or it can share a motion platform with the raw material A feeding hopper 4.
[0083] It also includes a raw material B feeding device, which comprises a raw material B rotary motor 35, a raw material B filling button, a robotic arm cabin, and a bottle B, which is the container containing raw material B. The raw material B rotary motor 35 holds the bottle B via the robotic arm cabin and controls the swing position of the bottle B, swinging it to the titration position below the titrator or the storage position of the bottle B according to the program settings. It also includes one motor, namely the raw material B cabin cover motor, and a robotic arm. The robotic arm is connected to the lid of the raw material B container, and the lid of the container containing raw material B is opened or closed by controlling the robotic arm to lift or lower.
[0084] The raw material B rotary motor 35 and the cockpit cover motor are industrial-grade standard servo motors, fixed to the core frame by sheet metal. The two motors are secured with sheet metal and screws to cooperate with the raw material B loading program. The complete workflow for loading raw material B is as follows: Clicking the "Load B" button causes the lifting motor to rise to the preset position. The raw material B cockpit cover motor controls the robotic arm to lift the cap of the B bottle. The raw material B rotary motor 35 rotates 90° clockwise to the titration position. At this point, the raw material B bottle is placed into the robotic arm cockpit of the raw material B rotary motor 35. Clicking the raw material B loading switch again causes the raw material B rotary motor 35 to rotate 90° counterclockwise to the B bottle storage position. The lifting motor 6 descends to the preset position, at which point the loading of B is complete.
[0085] The raw material B rotary motor 35 holds bottle B via a robotic arm cabin, removes the bottle cap, and swings bottle B to the titration position below raw material B titrator 32. Raw material B titrator 32 draws in solution B, then bottle B is moved back to its storage position and capped. The raw material C rotary motor 36 swings bottle C, which has been pre-stirred and contains activated water and powder C, to the titration position below raw material B titrator 32, adding solution B. After titration, the raw material C rotary motor 36 swings bottle C to the stirring position and begins stirring. After a predetermined stirring time, typically 5-10 minutes, the teeth whitening gel is ready. The various components work together to achieve contactless, automated stirring of liquids in a closed space.
[0086] A teeth whitening gel preparation machine comprises a touch screen located at the top front of the device for easy operation and human-computer interaction. It displays the start and status of the teeth whitening gel preparation process, as well as the preparation time, and can also be used for testing the machine. The outer casing serves as a protective shell for the internal components, offering an attractive appearance and facilitating operation and transport. Handles and a drag handle facilitate moving the machine. An indicator light displays the machine's operating status.
[0087] The host computer microcomputer serves as a platform for human-computer interaction and server interaction, and also needs to issue corresponding action commands to the slave computer's electronic control unit for execution. The slave computer's electronic control unit is mainly responsible for preparing logic programs for control and signal detection and judgment.
[0088] The main assembly comprises a motion platform integrating all actuators, motors, and sensors, enabling the teeth whitening gel preparation machine to automate the preparation of teeth whitening gel. The actuators include hydraulic / gas valves and a robotic arm. The power control box, located below the main assembly, supplies power to all components of the equipment.
[0089] The valve assembly is a valve control module used to control the on / off state of the gas source and switch between the gas path and the liquid path.
[0090] The valve assembly is located on the upper part and back of the equipment. "Valve assembly" is a general term for all valves. In this patent, the phrase "open or close valve assembly," or any mention of a valve assembly in a particular place, refers to the valve corresponding to the step of opening or closing the device or equipment, and not all valves.
[0091] Traditional hydraulic and pneumatic circuits use solenoid valves. Solenoid valves have a short lifespan, complex structure, and are prone to problems. Prolonged operation can cause them to overheat or burn out.
[0092] This patented valve assembly utilizes a servo motor system, controlling the valves in series via bus communication, resulting in simple wiring and easy maintenance. Flow rate can also be controlled by adjusting the valve angle. Because it employs a mechanical rotation combined with a servo motor for angle control, the valves can maintain a single state for extended periods, eliminating the risk of overheating or burnout from prolonged power-on. The servo motor controls the valve switching on a bracket. The mechanical valves are completely isolated from the servo motor, preventing liquid corrosion of the circuit components.
[0093] The liquid dispensing valve assembly controls the liquid dispensing needle assembly of raw material A through the liquid dispensing gas valve assembly of bottle A, so that raw material A in bottle A enters the activation reactor. After activation, the activated water is injected into bottle C through the liquid dispensing needle assembly under the control of the exhaust valve assembly of the activation reactor module, the liquid dispensing valve assembly of bottle C, and the liquid dispensing gas valve assembly of bottle C. Example 2
[0094] A teeth whitening gel preparation system includes a teeth whitening gel preparation machine as described in any of the above embodiments, and also includes a cloud server for managing the equipment's operating status and for storing preparation data and data.
[0095] The gel prepared by this patented device can be used in dental clinics, oral hospitals, and cosmetic surgery institutions to assist doctors in performing a cold light bleaching reaction on yellow teeth, sensitive teeth, tea-stained teeth, tobacco-stained teeth, as well as intrinsic fluorosis and tetracycline-stained teeth, decomposing pigment groups on the tooth surface and restoring the teeth to their natural color. It can also be used to kill bacteria and viruses on various skin surfaces or oral mucosa, such as treating inflammatory infections like acne and gingivitis. Example 3
[0096] A method for preparing teeth whitening gel involves clicking an automatic activation button on a touchscreen display. The program controls a lowering door to descend, while a rotating motor controls a robotic arm to move the raw material C to the outlet. Upon completion, a command is sent back to the touchscreen display, indicating that loading is ready. After loading is complete, clicking the touchscreen display confirms the placement of bottle C, which is the container containing raw material C. After successful placement, the production date is recorded, and the expiration date is set. The lowering door then rises and closes. A password is entered to initiate the preparation process.
[0097] As shown in Figure 6, the preparation process begins with the raw material A discharge motor driving the A bottle feed dial to rotate, transporting raw material A from the raw material A loading hopper to the designated position, i.e., the raw material A extraction and loading position. The extracted waste A bottle is then discarded into the A bottle waste hopper. The A bottle waste hopper collects containers that have had raw material A extracted. After this action is completed, the lifting motor begins to rise, entering the extraction position. The valve is opened, and pressure is applied to extract raw material A into the activation reactor. Once the liquid has been extracted, the activation reactor is started for activation, and the lifting motor begins to descend. At this time, the raw material C rotary motor, via a robotic arm, moves bottle C to the filling position, which is the same position as the stirring position. The raw material B rotary motor, via a robotic arm, moves bottle B to the titration position, where the raw material B titrator draws in raw material B for titration. Bottle B is the container containing raw material B.
[0098] Once the activation reactor is complete, the valve is opened to pressurize and fill the activated raw material into container C (bottle C). The stirring device is then activated with magnetic stirring. After filling, the lifting motor raises the raw material B titrator. The raw material B rotary motor, via a robotic arm, moves bottle B to its storage position. The raw material C rotary motor, via a robotic arm, moves bottle C to the titration position. The raw material B titrator then titrates the drawn raw material B into the filled bottle C. Once titration is complete, the raw material C rotary motor, via a robotic arm, moves bottle C to the stirring position. Magnetic stirring continues until the preparation is complete.
[0099] Once preparation is complete, the touchscreen display will show the countdown ending and indicate completion. Click the "Open Door" button to lower the lifting door. The raw material C rotary motor, via a robotic arm, will transport bottle C to the outlet position. The finished product can then be retrieved.
[0100] Raw material A, raw material B, and raw material C each represent a single raw material or a mixture of several raw materials.
[0101] Raw material A is a 2.5%-6% hydrogen peroxide solution, with 6% being the most effective. It is packaged in a 5ml bottle sealed with a rubber stopper. Raw material B is a neutralizing agent, mainly composed of a 10% sodium hydroxide solution, packaged in an 8ml bottle sealed with a rubber stopper. Raw material C is carbomer, weighing 0.02-0.08g, with 0.04g being optimal for a single preparation. Raw material C and a stir bar are packaged in a bottle, which is bottle C. In the teeth whitening gel preparation machine of this patent, the distance of the motor-driven lifting platform is highly repeatable. Bottle A will have a certain amount of liquid residue. A single preparation requires 3ml of raw material A, with approximately 0.2ml of A solution remaining, approximately 0.2ml of raw material B, and 0.04g of raw material C. An activation time of 5-10 minutes is required, with 7 or 8 minutes being optimal, at which point the activated water reaches a stable state. The volume ratio of hydrogen peroxide solution to neutralizing agent is 15:1. This ratio produces a consistency that is just right, allowing it to adhere to teeth, and a suitable pH level. Stirring time is generally 5-10 minutes.
[0102] Mixture 1: 3.2 ml of 2.5% hydrogen peroxide solution, 0.2 ml of neutralizer whose main component is 10% sodium hydroxide solution, and 0.02 g of carbomer.
[0103] Formula 2: 3.2 ml of 3% hydrogen peroxide solution, 0.2 ml of neutralizing agent whose main component is 10% sodium hydroxide solution, and 0.04 g of carbomer.
[0104] Formula 3: 3.2 ml of 6% hydrogen peroxide solution, 0.2 ml of neutralizing agent whose main component is 10% sodium hydroxide solution, and 0.08 g of carbomer.
[0105] The three formulations described above, when prepared using the teeth whitening gel preparation machine of this application, can be directly applied to the tooth surface with little difference in effect. Formulation 3 shows the best effect, does not require a gum protectant, has a clear teeth whitening effect, and can greatly reduce the risk of common allergies and post-whitening pain caused by high-concentration hydrogen peroxide gel.
[0106] Clinical results show that the whitening gel and whitening liquid prepared using the equipment of this invention are non-toxic, non-irritating, and odorless. No gel residue remains after rinsing, and they have a very good teeth whitening effect.
[0107] The teeth whitening effect can be adjusted by modifying the concentration of hydrogen peroxide solution in raw material A, the activation time of the activation reactor, the thickness of the gel coating on the teeth, and the time the gel acts on the teeth whitening process.
[0108] The 40 participants in the clinical trial had yellow teeth due to common extrinsic staining. They were divided into two groups of 20 each. The experimental group used Formula 2 and the teeth whitening gel prepared by this device. The control group used 3 ml of ultrapure water instead of activation ingredient A, 0.2 ml of 10% sodium hydroxide solution as the neutralizing agent, and 0.04 g of carbomer, and the gel was prepared manually.
[0109] The whitening method involves applying gel to the tooth surface three times, with each whitening session lasting 15 minutes. A cold light lamp is used during the process to catalyze stimulation, for a total treatment time of 45 minutes. No gum protectant was used before whitening, and no desensitizing agent was used afterward.
[0110] The whitening effect was mainly evaluated and analyzed using the VITA Bleachedguide 3D-Master colorimeter, a commonly used clinical method for intuitive visual effect analysis.
[0111] A shade guide (using the Vita shade guide as an example) determines tooth color using three values: brightness, saturation, and chroma. Column M represents intermediate colors, column L leans towards yellow, and column R leans towards red. First, compare brightness horizontally. Find the group with the highest brightness from darkest to lightest among the five groups (1, 2, 3, 4, 5). Second, compare saturation vertically and find the one with the best saturation. Finally, compare chroma values horizontally.
[0112] The teeth whitening gel prepared by this device has excellent whitening effect, with a difference in tooth color gradation ΔE between 3 and 8 shades before and after whitening, and none of the subjects experienced any soreness after the procedure.
[0113] The control group, using the same gel application and color matching methods, showed that the difference in tooth color gradation ΔE before and after whitening increased to nearly 0 shades.
[0114] Statistical analysis software was used to perform statistical analysis on the experimental results. Results are expressed as mean ± standard deviation, and a normality test was performed. Independent samples t-tests or rank-sum tests were used to compare the sample group and the control group. All statistical analyses were two-tailed tests with a significance level of α=0.05. The difference in tooth shade before and after whitening in the sample group was ΔE=3.90±1.14. The difference in tooth shade before and after whitening in the control group was ΔE=0.00±0.00. The change in shade after product use in the sample group was highly significant compared to the control group (P<0.01), indicating that the teeth whitening gel prepared by this device has a highly significant difference in effect compared to the control group.
