Description

Technical Field

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

[0002] As we age, the enamel of our teeth becomes thinner and thinner, gradually revealing the original yellow color of the dentin. Over time, pigments produced by food residues and bacteria in dental plaque are deposited on the surface of the teeth, causing the teeth to gradually turn yellow.

[0003] From ancient times to the present, humans have been exploring methods for whitening teeth. At present, tooth whitening gels containing hydrogen peroxide or carbamide peroxide as active ingredients are the most commonly used methods for tooth whitening. Carbamide peroxide can gradually release hydrogen peroxide, thereby reducing the sensitivity of teeth to whitening gels. This gel can bring better comfort to patients. However, among the existing tooth whitening products, there is a lack of ready-to-use methods for clinics. Most of them are directly produced in batches by factories, and the method of use is to open and use directly. In addition, the concentration of carbamide peroxide or hydrogen peroxide contained in existing clinic tooth whitening products is significantly higher (usually 17-35%). High concentrations of hydrogen peroxide can easily damage teeth and gums.

[0004] Problems with existing technical solutions: Tooth whitening gels are mostly finished products produced directly by factories, and the products are distributed and sold to corresponding clinics. There are problems with the preservation and shelf life of the finished products in the process of reaching users, which leads to reduced product effectiveness or even failure. The oxidant concentration of existing products is too high, which will seriously affect the health of the user's teeth and gums. In addition, the raw material control of products produced by the factory is invisible. The existing method of using low-temperature plasma to activate hydrogen peroxide solution to prepare tooth whitening gel is only a laboratory principle device and method, and there is no technical equipment that can be applied on a large scale. The effective time of plasma-activated water is short (generally 1-7 days). Therefore, tooth whitening gel that can be automatically prepared, ready-made, and has good whitening effect and no damage will become a future consumer trend, overcoming the clinical pain points of the traditional model and bringing consumers a better experience and sense of ritual. Summary of the invention

[0005] The main purpose of the present invention is to overcome the defects of the above-mentioned prior art and develop a teeth whitening gel preparation machine, comprising: a raw material A feeding device, an activation reaction device, a raw material B titration device, and a stirring device; the raw material A is fed into the activation reaction device for activation through the raw material A feeding device, and then enters the stirring device for stirring after activation. Before the secondary stirring, the raw material B is dripped into the raw material B through the raw material B titration device, and then fully stirred, so as to automatically prepare the teeth whitening gel.

[0006] Most of the existing teeth whitening gels are finished products directly produced by factories, and the products are distributed and sold to corresponding clinics. There are problems with the preservation and shelf life of the finished products in the process of reaching users, which leads to reduced product effectiveness or even failure. A teeth whitening gel preparation machine of the present invention is a relatively small device that can overcome the shortcomings of the short shelf life of low-temperature plasma teeth whitening gel (generally 1-7 days), and automatically prepares plasma teeth whitening gel on-site, which can be used on-site to maintain the activity of the product. It is suitable for on-site production of teeth whitening gel in hospitals, dental clinics and other institutions. The raw material A feeding device, the activation reaction device, the raw material B titration device, and the stirring device cooperate with each other to automatically prepare the teeth whitening gel. The setting of the raw material B titration device facilitates the production of teeth whitening gel with better quality.

[0007] Raw material A and raw material B represent different raw materials. Raw material A can be a raw material, such as hydrogen peroxide solution, or a mixture of hydrogen peroxide and other raw materials. Raw material B can be a raw material, such as a neutralizer, or a mixture of multiple raw materials. This technical solution is a technical solution of the equipment, and other feasible raw materials can also be prepared by this preparation machine.

[0008] Preferably, the raw material A feeding device comprises a raw material A discharging motor and a raw material A feeding bin, wherein the raw material A discharging motor is used to drive the container containing the raw material A to enter the feeding position. The motor and the raw material A feeding bin are matched to realize automatic feeding.

[0009] More preferably, the raw material A loading bin is a rectangular cavity with a smooth bottom surface, which is used to cache containers containing raw material A, is tilted, and the loading position is at the lowest point. The activation reaction device is arranged at one end of the loading position of the raw material A loading bin.

[0010] The raw material A loading bin is tilted so that the raw material A bottle can slide to the lowest point by its own weight, which is conducive to smoother loading. The bottom of the raw material A loading bin is smooth, and the smooth bottom can be achieved by affixing a smooth polytetrafluoroethylene patch or the like.

[0011] This design has been confirmed to be more scientific through repeated experiments, and is convenient for the coordination of various parts in the equipment. For example, it slides down to approach the activation reactor, making the coordination of various parts more convenient to realize the automation process; production, processing and maintenance are more convenient, saving costs. Of course, other solutions for setting the raw material A feeding bin horizontally can also be adopted, giving the container of raw material A a certain force to make it reach the feeding position. This technical solution has a complex structure, is inconvenient for production, processing and maintenance, and has high costs.

[0012] More preferably, a motion platform is further included, and the raw material A loading bin is arranged on a motion platform, and the motion platform is driven up and down by a lifting motor. Automatic loading is achieved through the motion platform to complete automated preparation.

[0013] More preferably, the raw material A feeding device also includes a raw material A liquid extraction needle assembly, and the raw material A is allowed to enter the activation reaction device through the raw material A feeding device, specifically by driving the moving platform to rise through a lifting motor, thereby driving the raw material A loading bin of the container containing raw material A to rise, while the liquid extraction needle and gas needle assembly of the raw material A liquid extraction needle assembly do not move, so that the liquid extraction needle and gas needle are inserted into the container containing raw material A, and the gas needle is connected to the diaphragm pump through a hose, and starts to blow air into the closed container containing raw material A, and the liquid extraction needle is connected to the activation reaction device through a pipeline, so that raw material A enters the activation reaction device through the liquid extraction needle and the pipeline. More preferably, the raw material B titration device includes a raw material B titrator, and the raw material B titrator can be raised and lowered. Thereby, the automatic absorption of raw material B is realized.

[0014] More preferably, the titrator for raw material B and the loading bin for raw material A are arranged on a moving platform.

[0015] The raw material A loading bin is arranged on a moving platform, and the raw material B titrator is arranged on another moving platform, and the lifting control can be realized respectively. The raw material A loading bin and the raw material B titrator can also be arranged on a moving platform, which can save a motor, save costs, and save space in the equipment, making the preparation machine miniaturized. Each time the raw material A loading bin or the raw material B titrator needs to be lifted or lowered, the same moving platform is lifted or lowered as a whole.

[0016] More preferably, it also includes a raw material B feeding device, which includes a container containing raw material B. The raw material B feeding device is arranged under the moving platform, and the moving platform is driven down by a lifting motor, thereby driving the raw material B titrator to descend, and the pipette of the raw material B titrator is inserted into the container containing raw material B to suck raw material B into the raw material B titrator.

[0017] The above scheme can realize that the raw material B titrator automatically absorbs raw material B.

[0018] Preferably, the lifting motor controls the lifting of the motion platform through a coupling and a screw rod. The lifting motor controls the lifting of the motion platform through a coupling and a screw rod, which can achieve lifting in a small space.

[0019] More preferably, it also includes a waste bin, which is arranged below the upper bin of raw material A. After the raw material A in the container is emptied, it is automatically transferred into the waste bin before the next preparation.

[0020] Raw material A is placed in a closed container containing raw material A, which can keep raw material A clean and free from contamination. The waste bin is set below the upper bin of raw material A to facilitate the automatic collection of empty containers of raw material A. The empty containers of raw material A can be reused after cleaning, so it is very necessary to collect the empty containers containing raw material A.

[0021] More preferably, it also includes a raw material B rotating motor, which is located below the motion platform. The raw material B feeding device includes a raw material B rotating motor, which drives the container containing raw material B to rotate to the position where the raw material B titrator extracts raw material B or the container containing raw material B is stored through a mechanical arm.

[0022] Because the raw material B titrator is set on the moving platform, the raw material B rotating motor and the container containing raw material B are located below the moving platform, which is convenient for the raw material B titrator to suck in raw material B. The position where the raw material B titrator extracts raw material B and the position where raw material B is dropped into the container of raw material C are at the same position, so after the raw material B titrator sucks in raw material B, the raw material B bottle needs to return to the raw material B bottle storage position to make room for the container of raw material C, so that the raw material C rotating motor rotates the container containing raw material C and the stirrer to the titration position through the mechanical arm, and the raw material B titrator drops the sucked raw material B into the container containing raw material C and the stirrer. The sequential action steps between each motor are realized through automatic program control, and the positional relationship of each component is combined to realize automatic control in a smaller preparation machine.

[0023] More preferably, the raw material B feeding device also includes a motor and a robotic arm, the motor is connected to the cover of the container containing raw material B, and the cover of the container containing raw material B is opened or closed by controlling the robotic arm to lift or lower.

[0024] The opening or closing of the container cover of raw material B is controlled by a motor, and full automation is achieved. The raw material B in the container of raw material B is more than the amount sucked by the raw material B titrator each time. The raw material B in the container of raw material B can be sucked by the raw material B titrator multiple times to prepare multiple teeth whitening gels. Therefore, it is particularly important that the raw material B titrator automatically opens the bottle cover before sucking raw material B and automatically closes the bottle cover after sucking to prevent raw material B from deteriorating.

[0025] More preferably, the container cap is removed at the storage position of the container containing raw material B, and then the container containing raw material B is driven by the robot arm to rotate to the position where the raw material B titrator extracts raw material B. After the extraction is completed, the container containing raw material B is rotated to the storage position, and then the container containing raw material B is covered. The above steps and the cooperation between various components realize automatic control.

[0026] Preferably, the activated solution is poured into a stirring device after entering the stirring device, and the stirring device contains a raw material C and a stirring bar. The raw material C can be a single raw material, such as carbomer, or a mixture of multiple raw materials. The various preparation links and raw materials are connected automatically.

[0027] More preferably, it also includes a raw material C feeding device, which includes a raw material C rotating motor for rotating the container containing the raw material C and the stirrer to the outlet position, the stirring position or the titration position through a mechanical arm.

[0028] At the outlet position of the container containing raw material C and a stirrer, the container can be taken out and put in; the stirring position of the container containing raw material C and a stirrer is the position for stirring and activating raw material A, and is also the pouring position of activated raw material A into the container containing raw material C and a stirrer; the raw material B titrator drips raw material B into the container containing raw material C and a stirrer at the titration position. During the preparation of teeth whitening gel, the raw material C rotating motor swings the container of raw material C between these three positions through a mechanical arm, thereby realizing the automated preparation of teeth whitening gel.

[0029] More preferably, it also includes a lifting door, which is arranged at the outermost side of the movement assembly. When the teeth whitening gel is prepared, the lifting door is lowered to take out the teeth whitening gel.

[0030] The lifting door is precisely controlled by a lifting door motor, a screw rod and a slide rail system. Through the lifting door, the container of the raw material C can be placed in or taken out of the raw material C cabin.

[0031] Preferably, the stirring device is a magnetic stirring device, and the motor drives the magnetic device to rotate, thereby attracting the magnetic stirring bar in the container of the raw material C to rotate. The raw materials can be stirred in a closed space without contact and automatically, thereby ensuring the medical-grade cleanliness standard and production efficiency of the consumables.

[0032] More preferably, it also includes a touch display device for human-computer interaction and displaying the preparation time and status, so as to realize automatic control and facilitate management.

[0033] More preferably, the on and off of the valve gas and liquid pipeline is automatically controlled by a program-controlled motor; the valve is a mechanical valve, the motor is a servo steering gear, the mechanical valve is completely isolated from the servo steering gear, the servo steering gear controls each valve through bus communication, and controls the flow rate by controlling the angle of the valve.

[0034] The opening and closing of each valve is automatically controlled, which makes it feasible to realize the automated preparation of teeth whitening gel. The circuit is simple and easy to maintain. The valve switch can maintain a state for a long time, and there is no situation of heating or even burning due to long-term power supply. The mechanical valve is completely isolated from the servo motor to prevent liquid from corroding the circuit components.

[0035] More preferably, it also includes a radio frequency identification (RFID) module for encoding and tracking the raw material C bottle, so as to facilitate the detection of relevant information of the C bottle and its expiration date.

[0036] More preferably, it also includes a grip in the shape of a groove, which is arranged in the middle of the left and right sides of the preparation machine, or at the upper or lower position of the middle part, for carrying the preparation machine. This design allows a place to grasp during the carrying process, thereby facilitating the carrying.

[0037] More preferably, the machine further comprises wheels at the bottom of the drag handle disposed on the upper part of the machine for moving the machine, making it more convenient to move the machine.

[0038] Also included is a teeth whitening gel preparation system, including any of the teeth whitening gel preparation machines described above, and also including a cloud server to manage the device operation status, the collection and database storage of preparation data. The cloud server enables remote management of the teeth whitening gel preparation machine and can also save preparation data.

[0039] The invention also includes a method for preparing a teeth whitening gel. After the container containing raw material A in the raw material A loading bin 4 is transported to the loading position, the lifting motor 6 drives the raw material A loading bin 4 to start rising, and brings the raw material A loading bin 4 to the extraction position; the raw material A is extracted into the activation reactor under pressure; after the raw material A liquid is extracted, the activation reactor 1 is powered on, and the lifting motor 6 drives the raw material A loading bin 4 to start descending; at this time, the raw material C rotating motor 10 drives the container containing raw material C and a stirrer (referred to as C bottle) to the stirring position; the raw material B rotating motor 9 drives the container containing raw material B to the dropping position. The raw material B titrator 5 starts to descend, sucks the raw material B and waits for titration; when the activation of the activation reactor 1 is completed, the activated raw material A is filled into the C bottle, and the stirring device 11 is turned on for preliminary stirring; after the filling is completed, the lifting motor 6 drives the raw material B titrator 5 to start rising; the raw material B rotating motor 9 drives the container with the raw material B to the storage position; the raw material C rotating motor 10 drives the C bottle to the titration position, and the raw material B titrator 5 starts to titrate the raw material B into the C bottle; after the titration is completed, the raw material C rotating motor 10 drives the C bottle to the stirring position, and continues the magnetic stirring until the preparation of the teeth whitening gel is completed.

[0040] Raw material A and raw material B represent different raw materials. Raw material A can be a raw material, such as hydrogen peroxide solution, or a mixture of hydrogen peroxide and other raw materials.

[0041] The beneficial effect of the method is that the tooth whitening gel preparation machine automatically prepares the tooth whitening gel, which is convenient and hygienic. The various components of the preparation machine are perfectly matched, and the preparation process is performed step by step. This perfect match is attributed to the layout of the internal components and the perfect match of the installation position relationship, connection relationship and preparation process.

Product information is recorded uniformly, and the use of raw materials and finished products can be queried in the cloud server. The device can achieve the whitening effect of high-concentration hydrogen peroxide by activation using low-concentration hydrogen peroxide, and does not damage teeth and gums.

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.

[0046] The modules, units, mechanisms, devices, etc. involved in this patent 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 patent application. 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.

[0047] Example 1

[0048] Raw material A feeding device, activation reaction device, raw material B titration device, stirring device; raw material A enters the activation reaction device for activation through the raw material A feeding device, enters the stirring device for stirring after activation, and raw material B is dripped into the raw material B titration device before secondary stirring, and then fully stirred to automatically prepare teeth whitening gel.

[0049] The above-mentioned devices cooperate with each other to automatically prepare the teeth whitening gel, which can improve the preparation accuracy and facilitate the production of teeth whitening gel with better quality.

[0050] Raw material A and raw material B represent different raw materials. Raw material A can be a raw material, such as hydrogen peroxide solution, or a mixture of hydrogen peroxide and other raw materials. Raw material B can be a raw material, such as a neutralizer, or a mixture of multiple raw materials. This technical solution is a technical solution of the equipment, and other feasible raw materials can also be prepared by this preparation machine.

[0051] The following describes in detail the raw material A feeding device, activation reaction device, raw material B titration device, stirring device, raw material B feeding device, raw material C feeding device, liquid extraction valve assembly, control system and the structures and mutual positions and coordination relationships of each device, and the method for preparing teeth whitening gel and the formula ingredients are described in detail.

[0052] Figure 1-Figure 3The structure of a tooth whitening gel preparation machine shown in the figure includes an activation reactor 1, a waste bin 2, a lifting door 3, a raw material A loading bin 4, a raw material B titrator 5, a lifting motor 6, a liquid taking valve assembly 7, a raw material A discharging motor 8, a raw material B rotating motor 9, a raw material C rotating motor 10, a stirring device 11, and an A bottle feeding dial 12. These components are encapsulated in a preparation machine movement assembly by metal materials such as sheet metal, lead screws, and screws.

[0053] The raw material A feeding device comprises a raw material A feeding bin 4, a raw material A discharging motor 8, an A bottle feeding dial 12, a bottle dialing shaft, and an A bottle. The container containing the raw material A is referred to as an A bottle.

[0054] The raw material A loading bin 4 is used to cache the raw material A. The raw material A is placed in the A bottle. After the raw material A is extracted, the empty A bottle will be automatically discarded to the waste bin 2 before the next preparation. The waste bin 2 is a device for collecting and storing the empty A bottles after the A liquid is extracted.

[0055] The raw material A discharging motor 8 is used to drive the feeding of the A bottles and the discarding of the A bottles.

[0056] The A bottle feeding dial 12 is integrated on the raw material A loading bin 4 and is used for aligning the discarded bottles of A bottles with the loading of the bottles.

[0057] The raw material A feeding device includes a raw material A feeding bin 4, which is a rectangular cavity with a smooth bottom surface, used to cache containers containing raw material A, and is tilted. The feeding position is at the lowest point, and the activation reaction device is arranged at one end of the feeding position of the raw material A feeding bin. The raw material A feeding bin 4 is provided with a sheet metal base and a light shielding cover. The sheet metal base is affixed with a polytetrafluoroethylene slide to facilitate the downward sliding of the A bottle during the feeding process. The sheet metal base can also be other relatively smooth materials, not limited to polytetrafluoroethylene. The light shielding cover and the base are connected by screws, and the light shielding cover can be opened during feeding and closed after feeding. The raw material A discharging motor 8 and the A bottle feeding dial 12 and the bottle dialing shaft are connected by screws, and the raw material A discharging motor 8 drives the A bottle feeding dial 12 and the bottle dialing shaft to rotate. There are 6 evenly distributed grooves on the bottle dialing shaft, and the curvature of each groove corresponds to the curvature of the A bottle body, and the A bottle is driven to rotate by the rotation of the bottle dialing shaft. The A bottle feeding dial 12 is provided with 6 evenly distributed holes, which correspond to the 6 grooves driving the A bottle feeding dial 12 one by one, that is, the raw material A discharging motor 8 rotates the A bottle feeding dial 12 and the bottle dial shaft 60 degrees, the A bottle feeding dial 12 rotates from one hole to the position of the adjacent hole, and the bottle dial shaft rotates from the loading position corresponding to the A bottle in the groove to the loading position corresponding to the A bottle in the next groove. A dial position sensor is arranged on the upper part of the A bottle feeding dial 12, the raw material A discharging motor 8 rotates the A bottle feeding dial 12 and the bottle dial shaft, and passes through the hole of the A bottle feeding dial 12 at a fixed angle of 60 degrees, and the dial position sensor senses whether it rotates to the hole adjacent to the A bottle feeding dial 12. Once it rotates to the hole position, it is determined that it has rotated to the set position and stops rotating. The dial position sensor can be a photoelectric sensor, which relies on photoelectric sensing to determine whether it rotates to the set position of the A bottle feeding dial 12. Because the raw material A discharge motor 8 rotates the A bottle feed dial 12 and the bottle dial shaft at the same time, once the raw material A discharge motor 8 rotates to an adjacent hole position, the bottle dial shaft brings bottle A to the loading position. The material shortage detection sensor can be a photoelectric sensor or a gravity sensor. After detecting the presence of bottle A, the raw material A discharge motor 8 drives the A bottle feed dial 12 and the bottle dial shaft to rotate a fixed angle to a fixed position, and the bottle dial shaft brings bottle A to the loading position, that is, the position where raw material A is extracted.

[0058] Bottle A slides down one by one in the raw material A loading bin 4 to load the bottle. Raw material A is sealed in a smooth bottomed vial, i.e., bottle A, with an aluminum-plastic cap.

[0059] It also includes a motion platform, and the raw material A loading bin is set on a motion platform, and the motion platform is driven to rise and fall by a lifting motor. When sucking raw material A, the platform lifting motor drives the raw material A loading bin 4 to rise to a fixed position, and the position control is realized by controlling the rotation angle of the motor through the communication drive of the lower computer. After the raw material A loading bin rises to a fixed position, the raw material A liquid collection needle assembly is inserted into the A bottle.

[0060] The raw material A liquid extraction needle assembly includes a curved gas needle, a straight liquid needle, a needle holder, a Luer connector, and a fixed sheet metal bracket. The bracket is set to adjust the vertical position of the entire liquid extraction module by lengthening the fixing screw hole, that is, the depth of the straight liquid needle inserted into bottle A, to ensure that the liquid in bottle A of raw material is fully discharged. The needle holder fixes the gas needle and liquid needle to the bracket through 4 screws, and the raw material A liquid extraction needle assembly is fixed on the sheet metal of the raw material A feeding device.

[0061] 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 1 downward after extraction. The activation reactor 1 is placed in the middle position of the teeth whitening gel preparation machine, which is also convenient for the liquid after startup to smoothly enter the C raw material bottle to prevent the occurrence of liquid reflux of raw material A after activation.

[0062] The raw material A loading bin is arranged on a moving platform, and the moving platform is driven to rise and fall by a lifting motor.

[0063] As shown in Figures 1 and 2, the lifting motor 6 (with Figure 3 The stepper motor 33 is a component) located directly below the motion platform 42, fixed to the movement frame 41 of FIG. 3 by screws, connected to the motion platform 42 by couplings 34 and screws 35, and integrated on the motion platform 42 are components such as the raw material A loading bin 4, the raw material B titrator 5, and the raw material A discharging motor 8. Each component is fixed to the motion platform by sheet metal fixings and screws, and the entire module presents an up-and-down structure. The motor controls the lifting and lowering operation of the entire lifting platform 42 through the coupling 34 and screws 35. Then indirectly control the up-and-down movement of the raw material A loading bin 4 and the raw material B titrator 5. The working procedures of the lifting motor 6 and the raw material A loading bin 4 are set as follows: a smooth polytetrafluoroethylene patch is attached to the bottom of the raw material A loading bin. After the raw material A bottle is loaded, the raw material A bottle slides down to the groove of the bottle-moving shaft by its own weight. The sensor recognizes the raw material A bottle, and the program instructs the bottle-moving shaft to rotate the A bottle to the loading position. The lifting motor 6 drives the screw 35 to control the entire lifting platform 42 to rise, so that the raw material A loading bin of the A bottle rises, while the raw material A liquid extraction needle and gas needle assembly do not move, so that the liquid extraction needle and gas needle of the raw material A liquid extraction needle assembly are inserted into the A bottle. The gas needle is connected to the diaphragm pump through a hose and starts to blow air into the closed A bottle. The liquid extraction needle is inserted into the bottom of the A bottle and is connected to the activation reaction device through a hose, so that the raw material A enters the activation reaction device through the liquid extraction needle and the pipeline. The design of double needle insertion and pressurized extraction used to extract the raw material A liquid can ensure that the A liquid is in a fully enclosed environment before extraction. During the extraction process, the pressurized gas is filtered to ensure the cleanliness of the gas source. The bottle does not need to be 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 along the direction of the pressure pipeline.

[0064] The activation reactor 1 is on a dedicated platform on the right side of the lifting platform 42, and is connected to the entire movement integrated platform by sheet metal and screws. The waste bin 2 is below the raw material A discharge motor 8. When raw material A passes through the raw material A discharge motor 8, bottle A can fall into the waste bin 2 by its own weight. The waste bin 2 is manually pluggable. When the waste bin is full, the lifting door 3 is lowered, and the waste bin 2 can be taken out and the used empty bottles of raw material A can be poured out. The lifting door 3 is fixed to the outermost side of the movement assembly by sheet metal and screws, and the lifting and lowering of the lifting door 3 is controlled by the lifting door 3 motor, screw rod and slide rail. The raw material A loading bin 4, the raw material B titrator 5, the lifting motor 6, the liquid extraction valve assembly 7, and the raw material A discharge motor 8 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 6 and the screw rod 35. The container of raw material B, i.e., bottle B, is located below the motion platform 42. The container containing raw material B is driven by a robotic arm to rotate to a position where the raw material B titrator extracts raw material B or to a storage position of the container containing raw material B. There is also a motor and a robotic arm, and the robotic arm is connected to a cover-removing device for the container cover of raw material B, and the cover-removing device is used to control the opening or closing of the container cover containing raw material B.

[0065] The raw material C rotating motor 10 makes bottle C swing on a horizontal plane. Swing to the stirring position, or the outlet position, or the titration position. Bottles B and C swing on the same plane, which is convenient for bottles B and C to rotate alternately to the titration position during the preparation process. Bottle B rotates to the titration position to absorb raw material B, and bottle C rotates to the titration position to drip raw material B, which is convenient for the conversion of different positions of bottles B and C during the preparation process, and realizes automatic control.

[0066] The stirring device is fixed on the movement platform by screws. After the raw material C feeding control detects that there is raw material, the upper computer confirms and closes the door, and the program will issue instructions to control the raw material C rotating motor 10 to rotate to the specified position for stirring or titration.

[0067] The integrated design and top-down layout of the above components can not only effectively reduce costs, but also promote efficient and stable operation of the equipment and reduce the failure rate. For example, the raw material A loading bin 4, the raw material B titrator 5, the lifting motor 6, and the raw material A discharge motor 8 are integrated on a lifting platform 42, and the raw material B titration and raw material A bottle puncture process can be completed with one lifting motor 6, reducing the investment of one motor and effectively reducing costs and equipment failure rates. For example, the top-down layout of the activation reactor 1, the raw material A discharge motor 8, the liquid extraction valve assembly 7, the raw material B bottle, and the raw material C bottle can not only effectively reduce the length of the hose and save costs, but also effectively reduce the liquid retention in the hose during the liquid delivery process and improve the preparation accuracy.

[0068] The activation reactor 1 is used to activate the raw material A. The activation reactor comprises an activation reactor electrode driving plate unit, an activation reactor electrode, a liquid inlet and outlet unit, a gas inlet and outlet unit, and a liquid activation pool. The activation reactor electrode driving plate unit is located on the upper part of the activation reactor electrode, and the liquid activation pool is located on the lower part of the activation reactor electrode. The liquid activation pool and the activation reactor electrode form a closed cavity. It also comprises a cooling fan, an activation reactor shell, and a protective coil.

[0069] The liquid activation pool material is made of polytetrafluoroethylene, and the air inlet, exhaust port, drain port, and liquid inlet are pagoda heads made of food-grade PP material, which are fastened to the liquid activation pool by threads. The activation reactor electrode drive plate unit includes the activation reactor electrode drive plate, and the activation reactor electrode drive plate, the activation reactor electrode, and the liquid activation pool are fastened together by screws. The activation reactor shell covers the activation reactor electrode drive unit, the activation reactor electrode, and the liquid activation pool. There is a cooling fan on one side of the activation reactor shell, and cooling holes are provided on the device shell opposite to the fan and on the other two sides. The fan works continuously during the working process of the activation reactor to ensure sufficient heat dissipation during the working process of the activation reactor.

[0070] The drain port 9 is placed at the bottom to fully drain the liquid without any residual liquid.

[0071] Working principle and process: When adding liquid, the raw material A liquid enters from the liquid inlet, the air inlet and the liquid discharge port are closed, and the exhaust port is opened, so that the liquid can enter the inverted pyramid-shaped liquid activation pool at the bottom. Then the activation reactor electrode drive plate unit drives the activation reactor electrode drive plate to discharge with high voltage for activation. After the activation is completed, open the air inlet and the liquid discharge port, and close the exhaust port and the liquid inlet. The air pump is connected to the air inlet through a silicone tube, blows air into the inverted pyramid-shaped liquid activation pool, and discharges the liquid out through the liquid discharge port. The raw material A solution is activated in the activation reactor and then injected into bottle C. The injection time is set to 30 seconds. During the injection of the activated A solution, the stirring device 11 is instructed to work at the same time, and the raw material B rotating motor 9 drives the raw material B cabin to reset. After the activated A solution is injected into bottle C, the raw material C rotating motor 10 is instructed to rotate to the titration position, and the lifting motor drives the screw rod 35 to control the motion platform 42 to fall to the top of bottle C and stop. At this time, the raw material B titrator 5 is facing the bottle mouth of bottle C, and the program instructs the lifting motor to press down the push rod of the raw material B titrator 5 to drop the B solution into bottle C.

[0072] The stirring device 11 includes a raw material C rotating motor 10, 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 bottle containing the raw material C, which can be a bottle or a container of other shapes.

[0073] The base of the stirring device 11 has two magnetic poles respectively. 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.

[0074] The stirring device 11 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.

[0075] 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.

[0076] 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.

[0077] It also includes a raw material C loading device, which includes a raw material C rotating motor 10, an infrared photoelectric sensor, a lifting door 3, and a raw material C cabin.

[0078] The raw material C rotating motor 10 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 3 drops to the preset position, and the raw material C cabin is exposed (initialization position). The RFID module is used to mark the coding 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 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 3 rises to the preset position. At this time, the loading of raw material C is completed.

[0079] The raw material C rotating motor 10 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 put in, and automatically clamps the C bottle after leaving the outlet.

[0080] The raw material C rotating motor 10 is a mechanism for providing power. The raw material C cockpit is controlled by the raw material C rotating motor 10, and the device can fix or loosen the C bottle. The raw material C cockpit is controlled by the raw material C rotating motor 10 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.

[0081] After the stirring is completed at the stirring position, the raw material C cockpit is controlled by the raw material C rotating motor 10 to swing the C bottle to the exit position of the C bottle, and the raw material C cockpit on the robot arm hits the limit block, and the cockpit's clamping force on the bottle becomes smaller, so that the bottle is in a relaxed and removable state. After the teeth whitening gel is prepared, the lifting door 3 is lowered, and the C bottle containing the teeth whitening gel is taken out.

[0082] 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 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.

[0083] The raw material B titration device includes a push rod stroke sensor, an electric push rod, a motion platform, and a raw material titrator 5. 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 5 is used to accurately set the volume of the titrated B raw material. The raw material titrator 5 can be provided with a separate motion platform to achieve lifting, or it can share a motion platform with the raw material A upper bin 4.

[0084] The raw material B feeding device includes a raw material B rotating motor 9, a raw material B filling button, a mechanical arm cockpit and a B bottle, which is a container containing raw material B. The raw material B rotating motor 9 clamps the B bottle through the mechanical arm cockpit, and the raw material B rotating motor 9 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.

[0085] The raw material B rotating motor 9 and the cockpit cover motor are industrial standard steering gears, fixed to the movement frame 41 by sheet metal, and the two motors are fixed by sheet metal and screws to cooperate with the operation of the raw material B loading program. The complete workflow of loading raw material B is: click the loading B button, the lifting motor 6 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 9 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 9, click the raw material B loading switch again, the raw material B rotating motor 9 rotates 90° counterclockwise to the B bottle storage position, and the lifting motor 6 descends to the preset position, and the B loading is completed.

[0086] The raw material B rotating motor 9 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 5, the raw material B titrator 5 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 10 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 5, drips the B solution, and after the titration is completed, the raw material C rotating motor 10 swings the C bottle to the stirring position, and then starts stirring. After stirring for a predetermined time, generally 5-10 minutes, the teeth whitening gel is prepared. The various parts of the device cooperate with each other to achieve the effect of contactless and automatic stirring of the liquid in a closed space.

[0087] like Figure 4 As shown, the overall composition of a teeth whitening gel preparation machine includes a touch screen 13, which is located at the front upper part of the device, is easy to operate, and is used for human-computer interaction, tooth whitening gel preparation start and preparation status display, and preparation time display. It can also be used to test the preparation machine. The shell 14 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 15, the drag handle 16 and the like Figure 6 The bottom wheels 23 are shown to facilitate the handling and movement of the tooth whitening gel preparation machine. The operation indicator light 17 is used to display the operation status of the device.

[0088] The upper computer microcomputer is a platform for human-computer interaction and server interaction, and it 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.

[0089] like Figure 6 As shown, the movement assembly 18 includes a motion platform in which all actuators, motors, and sensors are assembled, so that the teeth whitening gel preparation machine can automatically prepare teeth whitening gel. The actuator includes a liquid-steam valve and a mechanical arm. The power distribution control box 19 is located below the movement assembly 18 to supply power to various components of the device.

[0090] The liquid extraction valve assembly 7 is used to control the on-off of gas and liquid, and switch the valve control module between the gas circuit and the liquid circuit.

[0091] The liquid extraction valve assembly is located on the upper part and the back of the device. The liquid extraction valve assembly is a general term for all valves. In this patent, the opening or closing of the liquid extraction valve assembly, or the liquid extraction valve assembly involved somewhere, refers to the valve corresponding to the step of opening or closing the device or equipment.

[0092] 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.

[0093] The servo steering gear adopted by the liquid extraction valve assembly of the patent 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 heating or even burning due to long-term power-on. Figure 7 , Figure 8 As shown, the servo steering engine 20 mounted on the bracket 21 controls the switch of the valve 22. The mechanical valve is completely isolated from the servo motor to prevent liquid from corroding the circuit components.

[0094] like Fig. 9 As shown, the liquid taking valve assembly 7 controls the raw material A liquid taking needle assembly 32 through the A bottle liquid taking gas valve assembly 28 to make the raw material A in the A bottle 31 enter the activation reactor device 24. After activation, the activated water is controlled by the activation reactor module exhaust valve assembly 26, the C bottle liquid filling valve assembly 25, and the C bottle liquid filling gas valve assembly 27, and is injected into the bottle 29 through the injection needle assembly 30.

[0095] Raw material A, raw material B, and raw material C represent one raw material or a mixture of several raw materials respectively.

[0096] Raw material A is a hydrogen peroxide solution with a concentration of 2.5%-6%, and the best effect is 6%. It is canned in a vial sealed with a rubber stopper, that is, bottle A, and the volume of bottle A is 5ml. Raw material B is a neutralizer, the main component of which is a 10% sodium hydroxide solution. It is canned in a vial sealed with a rubber stopper, that is, bottle B, and the volume of bottle B is 8ml. Raw material C is carbomer, with a mass of 0.02-0.08g, and the best single preparation is 0.04g. Raw material C and a stirrer are placed in a vial, and bottle C is a vial. In the tooth whitening gel preparation machine of this patent, the distance repeatability of the lifting platform driven by the motor is good. Bottle A will have a fixed liquid residue. In a single preparation process, 3ml of raw material A is used, about 0.2ml of A liquid remains, about 0.2ml of raw material B, and 0.04g of raw material C. It takes 5-10min activation time, 7 or 8min is optimal, when the performance of activated water reaches a stable state. The volume ratio of hydrogen peroxide solution to neutralizer is 15:1. This ratio has just the right consistency to stick to teeth and has a moderate pH. The stirring time is generally 5-10 minutes.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] The teeth whitening effect can be adjusted by adjusting the concentration of the hydrogen peroxide solution in the raw material A, the activation time of the activation reactor, the thickness of the gel coating on the teeth, and the time the gel acts on the teeth for whitening.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] Example 2 A method for preparing a teeth whitening gel, wherein the automatic start button is clicked on a touch screen 13, and a program-controlled lifting door 3 begins to descend. The raw material C rotating motor 10 controls the mechanical arm to work to the exit. After the action is completed, an instruction is returned to the touch screen 13 to indicate that it can be loaded. After the loading is completed, the touch screen 13 is clicked to confirm that bottle C is put in, and at the same time, the device detects whether bottle C is put in. Bottle C is a container containing raw material C and a stirrer. After the detection of successful placement, the production date is recorded and the validity period is set. The lifting door 3 is controlled to start rising and the hatch is closed. Enter the password to start issuing instructions to start the preparation.

[0111] like Fig.10 As shown, at the beginning of the preparation, the raw material A discharge motor 8 drives the A bottle feed dial 12 to rotate, and the raw material A in the raw material A loading bin 4 is transported to the designated position, that is, the raw material A extraction loading position. The extracted waste bottle A is discarded into the A bottle waste bin 2. The A bottle waste bin 2 collects the container from which the raw material A has been extracted. After this action is completed, the lifting motor 6 starts to rise and enters the extraction position. Open the valve and pressurize to extract the raw material A into the activation reactor 1. Wait until the liquid is extracted and start the activation reactor 1 to power on, and the lifting motor 6 starts to descend. At this time, the raw material C rotating motor 10 runs the C bottle to the canning position through the mechanical arm. The canning position and the stirring position are the same position. The raw material B rotating motor 9 runs the B bottle to the titration position through the mechanical arm, and the raw material B titrator 5 absorbs the raw material B and waits for titration. Bottle B is the container containing raw material B.

[0112] After the activation reactor 1 is activated, the valve is opened to pressurize the raw materials after the start-up and can them into the container of raw material C, that is, bottle C, and the stirring device 11 starts magnetic stirring. After the canning is completed, the lifting motor 6 starts to drive the raw material B titrator 5 to rise, the raw material B rotating motor 9 moves bottle B to the storage position through the mechanical arm, and the raw material C rotating motor 10 moves bottle C to the titration position through the mechanical arm, and the raw material B titrator 5 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 10 moves bottle C to the stirring position through the mechanical arm, and the preparation is completed after continuing the magnetic stirring.

[0113] After the preparation is completed, the touch screen 13 shows the countdown is over, prompting completion. Click the hatch door opening button to control the lift door 3 to start descending, and the raw material C rotating motor 10 transports the C bottle to the exit through the mechanical arm. Then you can take the finished product, and after confirmation, the lift door 3 starts to rise and close the hatch door.

[0114] Example 3 A tooth whitening gel preparation system comprises the tooth 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 device and the preparation data and data storage.

[0115] The gel prepared by this patented device can be used in dental clinics, oral hospitals, medical beauty institutions and other scenarios to assist doctors in cold light bleaching of yellow teeth, sensitive teeth, tea-stained teeth, smoke-stained teeth, endogenous fluorosis, and tetracycline teeth, so as to decompose the pigment groups on the surface of teeth and restore the original color of teeth. It can also be used to kill various bacteria and viruses on the surface of the skin or oral mucosa, such as treating acne, gingivitis and other inflammatory infections.
