Description

Technical Field

[0001] The present invention relates to dental and oral hygiene devices, and particularly to a tooth whitening gel preparation machine and system. Background Art

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

[0003] Since ancient times, humans have been exploring methods for whitening teeth. Currently, tooth whitening gels containing active ingredients such as hydrogen peroxide or carbamide peroxide are the most commonly used tooth whitening methods. Carbamide peroxide can gradually release hydrogen peroxide, thereby reducing the sensitivity of teeth to the whitening gel. This gel can provide better comfort for patients. However, in existing tooth whitening products, there is a lack of an on-site preparation and immediate use method for clinic use. Most are directly mass-produced automatically by factories, and the usage method is to directly open and use. In addition, the concentration of carbamide peroxide or hydrogen peroxide contained in existing in-clinic tooth whitening products is significantly higher (usually 17 - 35%). High-concentration hydrogen peroxide is likely to damage teeth and gums.

[0004] Problems existing in the existing solution technology: Most tooth whitening gels are directly produced as finished products by factories and distributed and sold to corresponding clinics. There are problems with storage and shelf life during the process from the finished product to the user, resulting in a reduction or even failure of the product's use effect. The too-high concentration of oxidants in existing products seriously affects the dental and gum health of users. Additionally, the control of raw materials in factory-produced products is not visible. 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. Moreover, the effective time of plasma-activated water is short (generally 1 - 7 days). Therefore, a tooth whitening gel that can be automatically prepared, prepared and used immediately, has good whitening effect and no damage will become the future consumption trend, overcoming the clinical pain points of the traditional mode and bringing a better sense of experience and ritual to consumers. Summary of the Invention

[0005] The main purpose of the present invention is to overcome the defects of the above-mentioned existing technologies and develop a tooth whitening gel preparation machine, including: a raw material A feeding device, an activation reaction device, a raw material B titration device, and a stirring device; the raw material A enters the activation reaction device through the raw material A feeding device for activation, and after activation, it enters the stirring device for stirring. Before the secondary stirring, the raw material B is dropped into the stirring device through the raw material B titration device, and then fully stirred, automatically preparing the tooth whitening gel.

[0006] Most of the existing tooth whitening gels are directly produced as finished products in factories, and the products are distributed and sold to corresponding clinics. During the process from the finished product to the user, there are problems with storage and shelf life, resulting in a reduction or even failure of the product's use effect. A tooth whitening gel preparation machine of the present invention is a relatively small device, which can overcome the disadvantage of the short shelf life (generally 1 - 7 days) of low-temperature plasma tooth whitening gel, automatically prepare plasma tooth whitening gel on site, and be used on site to maintain the activity of the product. It is suitable for on-site production of tooth whitening gel in institutions such as hospitals and dental clinics. The raw material A feeding device, activation reaction device, raw material B titration device, and stirring device cooperate with each other to automatically prepare tooth whitening gel. The setting of the raw material B titration device facilitates the production of tooth whitening gel with better quality.

[0007] Raw material A and raw material B represent different raw materials. Raw material A can be a single raw material, such as hydrogen peroxide solution, or a mixture of hydrogen peroxide and other raw materials. Raw material B can be a single raw material, such as a neutralizing agent, or a mixture of multiple raw materials. This technical solution is for the equipment, and the preparation machine can also be used with other feasible raw materials.

[0008] Preferably, the raw material A feeding device includes a raw material A discharging motor and a raw material A feeding bin. The raw material A discharging motor is used to drive the container filled with raw material A to the feeding position. The cooperation of the motor and the raw material A feeding bin realizes automatic feeding.

[0009] Preferably, the raw material A feeding bin is a cuboid cavity with a smooth bottom surface, which is used to cache the container filled with raw material A. It is inclined, and the feeding position is at the lowest point. The activation reaction device is arranged at one end of the feeding position of the raw material A feeding bin.

[0010] The raw material A feeding bin is inclined, so that the raw material A bottle can slide to the lowest point by its own weight, which is beneficial to smoother feeding. The bottom of the raw material A feeding bin is smooth, and it can be achieved by pasting a smooth polytetrafluoroethylene patch, etc.

[0011] This design has been confirmed to be relatively scientific through repeated experiments, which is convenient for the cooperation of various components in the equipment. For example, when sliding down close to the activation reaction kettle, the cooperation of each part is more convenient to realize the automated process; production, processing, and maintenance are all relatively convenient, saving costs. Of course, other technical solutions with a horizontally arranged raw material A feeding bin can also be adopted, applying a certain force to the container of raw material A to make it reach the feeding position. However, this technical solution has a complex structure, is not convenient for production, processing, and maintenance, and has a high cost.

[0012] Preferably, it further includes a moving platform, and the raw material A feeding bin is arranged on a moving platform, and the moving platform is driven to lift by a lifting motor. Automatic feeding is realized through the moving platform to complete automated preparation.

[0013] Preferably, the raw material A feeding device further includes a liquid extraction needle assembly for raw material A. The raw material A enters the activation reaction device through the raw material A feeding device. Specifically, the lifting motor drives the moving platform to rise, thereby driving the raw material A feeding bin of the container filled with raw material A to rise. The liquid extraction needle and the air needle assembly of the liquid extraction needle assembly for raw material A remain stationary, so that the liquid extraction needle and the air needle penetrate into the container filled with raw material A. The air needle is connected to a diaphragm pump through a hose, and starts to blow air into the closed container filled with raw material A. 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. Preferably, the raw material B titration device includes a raw material B titrator, and the raw material B titrator can be lifted. Thus, automatic extraction of raw material B can be achieved.

[0014] Preferably, the raw material B titrator and the raw material A feeding bin are arranged on the same moving platform.

[0015] The raw material A feeding bin is arranged on one moving platform, and the raw material B titrator is arranged on another moving platform, and the lifting control can be realized separately. Or the raw material A feeding bin and the raw material B titrator can be arranged on one moving platform, which can save one motor, reduce costs, and also save the space inside the equipment, making the preparation machine miniaturized. Every time it is necessary to lift the raw material A feeding bin or the raw material B titrator, the whole moving platform is lifted.

[0016] Preferably, it further includes a raw material B feeding device. The raw material B feeding device includes a container filled with raw material B. The raw material B feeding device is arranged below the moving platform. The lifting motor drives the moving platform to descend, thereby driving the raw material B titrator to descend. The suction pipe of the raw material B titrator penetrates into the container filled with raw material B, and sucks raw material B into the raw material B titrator.

[0017] Through the above scheme, automatic extraction of raw material B by the raw material B titrator can be realized.

[0018] Preferably, the lifting motor controls the lifting of the moving platform through a coupling and a lead screw. The lifting motor controls the lifting of the moving platform through a coupling and a lead screw, and the lifting in a small space can be realized.

[0019] Preferably, it further includes a waste bin. The waste bin is arranged below the raw material A feeding bin. After the raw material A in the container filled with raw material A is emptied, it is automatically dialed into the waste bin before the next preparation.

[0020] Raw material A is packed in a closed container filled with raw material A, which can keep raw material A clean and free from contamination. The waste bin is arranged below the raw material A feeding bin, which is convenient for automatically collecting the empty containers of raw material A. The empty containers of raw material A can be reused after being cleaned, so it is very necessary to collect the empty containers filled with raw material A.

[0021] Preferably, it further includes a raw material B rotating motor, which is located below the moving platform. The raw material B feeding device includes the raw material B rotating motor, and drives the container containing raw material B to rotate to the position where the raw material B burette extracts raw material B or the storage position of the container containing raw material B through a robotic arm.

[0022] Since the raw material B burette is arranged on the moving platform, and the raw material B rotating motor and the container containing raw material B are located below the moving platform, it is convenient for the raw material B burette to suck in raw material B. The position where the raw material B burette extracts raw material B and the position where raw material B is dropped into the container of raw material C are the same position. Therefore, after the raw material B burette sucks in raw material B, the raw material B bottle needs to return to the storage position of the raw material B bottle to make room for the container of raw material C. Thus, the raw material C rotating motor drives the container containing raw material C and the stir bar to rotate to the titration position through a robotic arm, and the raw material B burette drops the sucked raw material B into the container containing raw material C and the stir bar. The sequential action steps between each motor are realized through automatic program control, and combined with the positional relationship of each component, automatic control can be achieved in a smaller preparation machine.

[0023] Preferably, the raw material B feeding device further includes one motor and a robotic arm. The motor is connected to the lid of the container containing raw material B, and controls the opening or closing of the lid of the container containing raw material B by controlling the lifting or lowering of the robotic arm.

[0024] Controlling the opening or closing of the lid of the container of raw material B through a motor fully realizes automation. The amount of raw material B in the container of raw material B is more than the amount sucked by the raw material B burette each time. The raw material B in the container of raw material B can be sucked by the raw material B burette multiple times for the preparation of teeth whitening gel multiple times. Therefore, it is particularly important to automatically open the bottle cap before the raw material B burette sucks in raw material B and automatically close the bottle cap after sucking to prevent the deterioration of raw material B.

[0025] Preferably, remove the container lid at the storage position of the container containing raw material B, then drive the container containing raw material B to rotate to the position where the raw material B burette extracts raw material B through a robotic arm. After extraction, rotate the container containing raw material B to the storage position, and then cover the container containing raw material B. Automatic control is achieved through the above steps and the cooperation between each component.

[0026] Preferably, after activation, it enters the stirring device, which means pouring the activated solution into the container containing raw material C and the stir bar in the stirring device. Raw material C can be one raw material, such as carbomer, or a mixture of multiple raw materials. Automatic preparation links and the connection between raw materials are carried out.

[0027] Preferably, it further includes a raw material C feeding device, which includes a raw material C rotating motor for driving the container containing raw material C and the stir bar to rotate to the outlet position, stirring position or titration position through a robotic arm.

[0028] At the outlet position of the container containing raw material C and the magnetic stir bar, the container can be taken out and put in; the stirring position of the container containing raw material C and the magnetic stir bar is the position for stirring the activated raw material A, and at the same time, it is also the pouring position where the activated raw material A enters the container containing raw material C and the magnetic stir bar; the raw material B burette titrates raw material B into the container containing raw material C and the magnetic stir bar at the titration position. During the preparation process of the teeth whitening gel, the raw material C rotating motor swings the container of raw material C between these three positions through the robotic arm, thus realizing the automated preparation of the teeth whitening gel.

[0029] Preferably, it further includes a lifting door which is arranged on the outermost side of the movement assembly. After the teeth whitening gel is prepared, the lifting door is lowered to take out the teeth whitening gel.

[0030] The precise control of the lifting door is realized by using the lifting door motor, the lead screw and the slide rail system. Through this lifting door, the container of raw material C can be placed into or taken out from the raw material C cockpit.

[0031] Preferably, the stirring device is magnetic stirring. The motor drives the magnetic device to rotate, thereby attracting the magnetic stir bar in the container of raw material C to rotate. It can achieve the effect of non-contact and automated stirring of the raw materials in a closed space, thus ensuring the medical-grade cleanliness standard and production efficiency of the consumables.

[0032] Preferably, it further includes a touch display device for human-machine interaction and displaying the preparation time and status. It can achieve automated control and is convenient for management.

[0033] Preferably, the on-off of the valve gas-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, and 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 are automatically controlled, which provides the feasibility for realizing the automated preparation of the 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 overheating or even burning out due to long-term power-on. The mechanical valve is completely isolated from the servo motor to prevent the liquid from corroding the circuit components.

[0035] Preferably, it further 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] Preferably, it further includes a handle which is in the shape of a groove and is arranged in the middle of the left and right sides of the preparation machine, or at a position above or below the middle, for carrying the preparation machine. This design enables there to be a place to grip during the carrying process, thus facilitating the carrying.

[0037] Preferably, it further includes wheels at the bottom of the dragging handle provided on the upper part of the preparation machine, which are used to move the preparation machine, making it more convenient to move the preparation machine.

[0038] It further includes a tooth whitening gel preparation system, which includes the tooth whitening gel preparation machine described in any one of the above, and further includes a cloud server for managing the running state of the device, summarizing the preparation data and storing it in the database. The cloud server enables remote management of the tooth whitening gel preparation machine and can also save the preparation data.

[0039] It further includes a tooth whitening gel preparation method. After the container filled with raw material A in the raw material A feeding bin 4 is transported to the feeding position, the lifting motor 6 drives the raw material A feeding bin 4 to start rising, bringing the raw material A feeding bin 4 to the extraction position; pressurize to extract raw material A into the activation reaction kettle; after the liquid of raw material A is completely extracted, start the activation reaction kettle 1 to work with power on, and the lifting motor 6 drives the raw material A feeding bin 4 to start descending; at this time, the raw material C rotating motor 10 runs the container (referred to as bottle C) filled with raw material C and the stirrer to the stirring position; the raw material B rotating motor 9 runs the container filled with raw material B to the titration position, and the raw material B titrator 5 starts to descend to suck raw material B and wait for titration; when the activation reaction kettle 1 is activated, fill the activated raw material A into bottle C and start preliminary stirring with the stirring device 11; after filling, the lifting motor 6 drives the raw material B titrator 5 to start rising; the raw material B rotating motor 9 runs the container filled with raw material B to the storage position; the raw material C rotating motor 10 runs bottle C to the titration position, and the raw material B titrator 5 starts to titrate raw material B into bottle C; after titration, the raw material C rotating motor 10 runs bottle C to the stirring position and continues magnetic stirring until the tooth whitening gel preparation is completed.

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

[0041] The beneficial effect of this method is that the tooth whitening gel preparation machine automatically prepares tooth whitening gel, which is convenient and hygienic. Each component of the preparation machine is perfectly coordinated to execute the preparation process step by step. This perfect coordination is attributed to the layout, installation position relationship, connection relationship of each internal component and the perfect coordination of the preparation process. The inventor has put in creative labor for this coordination of software and hardware.

[0042] The beneficial effects of the present invention are as follows: direct on-site preparation ensures the activity of the product. With this equipment, automated preparation of tooth whitening gel can be achieved, and accurate control of the ingredient ratio can be realized. Product information is uniformly recorded, and the usage of raw materials and finished products can be queried and recorded in the cloud server. This equipment can achieve the whitening effect of high-concentration hydrogen peroxide through activation using low-concentration hydrogen peroxide without damaging teeth and gums.

Whether it is a software module that realizes specific functions by relying on the operation of a software program or a hardware unit constructed based on physical circuits, mechanical structures, etc., they are all within the scope of writing of the patent application document. The description of their functions and logics focuses on the overall design concept, operation process, and achievable effects and goals, rather than being limited to the specific software and hardware implementation forms.

[0056] Embodiment 1

[0057] Raw Material A Feeding Device, Activation Reaction Device, Raw Material B Titration Device, Stirring Device; Raw Material A enters the activation reaction device through the raw material A feeding device for activation, and after activation, it enters the stirring device for stirring. Before the secondary stirring, raw material B is dripped into the mixture through the raw material B titration device, and then sufficient stirring is carried out to automatically prepare the teeth whitening gel.

[0058] The above-mentioned various 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.

[0059] Raw material A and raw material B represent different raw materials. Raw material A can be a single raw material, such as a hydrogen peroxide solution, or a mixture of hydrogen peroxide and other raw materials. Raw material B can be a single raw material, such as a neutralizing agent, or a mixture of multiple raw materials. This technical solution is for the equipment, and the same preparation mechanism can be used with other feasible raw materials.

[0060] The following will introduce 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, the structures of each device, their mutual positions and cooperation relationships, and will also elaborate on the method and formula for preparing teeth whitening gel.

[0061] Figures 1 - 3 The structure of a teeth whitening gel preparation machine shown includes an activation reaction kettle 1, a waste bin 2, a lifting door 3, a raw material A feeding bin 4, a raw material B titrator 5, a lifting motor 6, a liquid extraction 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 the preparation machine core assembly by metal materials such as sheet metal, lead screws, and screws.

[0062] The raw material A feeding device includes a raw material A feeding bin 4, a raw material A discharging motor 8, an A-bottle feeding dial 12, a bottle dialing rotating shaft, and an A-bottle. The container filled with raw material A is simply referred to as an A-bottle.

[0063] The raw material A feeding bin 4 is used to cache raw material A. Raw material A is contained in an A-bottle. After raw material A is extracted, the empty A-bottle will be automatically discarded into the waste bin 2 before the next preparation. The waste bin 2 is a device for collecting and storing the empty A-bottles after A liquid is extracted.

[0064] The raw material A discharging motor 8 is used to drive the feeding of the A-bottle and the discarding of the A-bottle.

[0065] The A-bottle feeding dial 12 is integrated on the raw material A feeding bin 4 and is used for aligning the discarding and feeding of the A-bottle.

[0066] The feeding device for raw material A includes a feeding bin 4 for raw material A. The feeding bin 4 for raw material A is a cuboid cavity with a smooth bottom, which is used to cache the containers filled with raw material A. It is inclined, and the feeding position is at the lowest point. The activation reaction device is arranged at one end of the feeding position of the feeding bin for raw material A. The feeding bin 4 for raw material A is provided with a sheet metal base and a light-shielding cover. The sheet metal base is pasted with a polytetrafluoroethylene sliding sheet to facilitate the downward sliding during the feeding process of bottle A. The sheet metal base can also be made of other relatively slippery materials, not limited to being pasted with polytetrafluoroethylene. The light-shielding cover and the base are connected by screws. The light-shielding cover can be opened during feeding and closed after feeding. The raw material A discharging motor 8, the A bottle feeding dial 12 and the bottle dialing rotating shaft are connected by screws. The raw material A discharging motor 8 drives the A bottle feeding dial 12 and the bottle dialing rotating shaft to rotate. There are 6 evenly distributed grooves on the bottle dialing rotating shaft, and the radian of each groove corresponds to the radian of the bottle body of bottle A. The rotation of the bottle dialing rotating shaft drives the rotation of bottle A. The A bottle feeding dial 12 is provided with 6 evenly distributed holes, which correspond one by one to the 6 grooves driving the A bottle feeding dial 12. That is, when the raw material A discharging motor 8 rotates the A bottle feeding dial 12 and the bottle dialing rotating shaft by 60 degrees, the A bottle feeding dial 12 rotates from one hole to the position of the adjacent hole, and the bottle dialing rotating shaft rotates from the position where one groove corresponds to the feeding position of bottle A to the position where the next groove corresponds to the feeding position of bottle A. A dial position sensor is arranged on the upper part of the A bottle feeding dial 12. The raw material A discharging motor 8 rotates the A bottle feeding dial 12 and the bottle dialing rotating shaft. The fixed angle of 60 degrees passes through the holes of the A bottle feeding dial 12, and the dial position sensor senses whether it rotates to the adjacent hole of 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 an optoelectronic sensor, which relies on optoelectronic induction to determine whether it rotates to the set position of the A bottle feeding dial 12. Because the raw material A discharging motor 8 rotates the A bottle feeding dial 12 and the bottle dialing rotating shaft at the same time, once the raw material A discharging motor 8 rotates to an adjacent hole position, the bottle dialing rotating shaft will bring bottle A to the feeding position. The material shortage detection sensor can be an optoelectronic sensor or a gravity sensor. After detecting bottle A, the raw material A discharging motor 8 drives the A bottle feeding dial 12 and the bottle dialing rotating shaft to rotate a fixed angle to a fixed position, and the bottle dialing rotating shaft will bring bottle A to the feeding position, that is, the position for extracting raw material A.

[0067] Bottle A slides out one by one from the feeding bin 4 for raw material A for bottle feeding. Raw material A is sealed in a vial with a smooth bottom by an aluminum-plastic cap, that is, bottle A.

[0068] It also includes a moving platform. The feeding bin for raw material A is arranged on a moving platform and is driven by a lifting motor to lift the moving platform. When sucking raw material A, the platform lifting motor drives the feeding bin 4 for raw material A to rise to a fixed position, and the position control is realized by driving and controlling the rotation angle of the motor through the communication of the lower computer. After the feeding bin for raw material A rises to the fixed position, the liquid extraction needle assembly for raw material A pierces into bottle A.

[0069] The liquid extraction needle assembly for raw material A includes a gas needle bent needle tip, a liquid needle straight needle tip, 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 through the elongated fixed screw holes, that is, the depth of the liquid needle straight needle tip inserted into bottle A of raw material A, to ensure that the liquid in bottle A of raw material A is fully discharged. The needle holder fixes the gas needle and the liquid needle on the bracket through 4 screws, and the liquid extraction needle assembly for raw material A is fixed on the sheet metal part of the feeding device for raw material A.

[0070] The position of the feeding device for raw material A is at the upper end of the tooth whitening gel preparation machine, which is convenient for the extracted liquid to enter the activation reaction kettle 1 downward. The activation reaction kettle 1 is placed in the middle position of the tooth whitening gel preparation machine, which is also convenient for the liquid after startup to smoothly enter the C raw material bottle, preventing the backflow of the liquid of raw material A after activation.

[0071] The raw material A feeding bin is arranged on a moving platform, and the moving platform is driven by a lifting motor to lift.

[0072] As shown in Figures 1 and 2, the lifting motor 6 (which is a component of Figure 3 the stepping motor 33) is located directly below the moving platform 42 and is fixed to the movement mechanism frame 41 in Figure 3 by screws. It is connected to the moving platform 42 through a coupling 34 and a lead screw 35. The moving platform 42 integrates components such as the raw material A feeding bin 4, the raw material B burette 5, and the raw material A discharging motor 8. Each component is fixedly connected to the moving platform through sheet metal fixing parts and screws. The entire module presents an up-and-down structure, and the motor controls the lifting operation of the entire lifting platform 42 through the coupling 34 and the lead screw 35. Thereby indirectly controlling the up-and-down movement of the raw material A feeding bin 4 and the raw material B burette 5. The working procedures of the lifting motor 6 and the raw material A feeding bin 4 are set as follows: A smooth polytetrafluoroethylene patch is attached to the bottom of the raw material A feeding bin. After filling the raw material A bottle, the raw material A bottle slides down to the groove of the bottle dialing shaft by its own weight. The sensor recognizes the raw material A bottle, and the program commands the bottle dialing shaft to rotate the A bottle to the feeding position. The lifting motor 6 drives the lead screw 35 to control the entire lifting platform 42 to rise. Thus, the raw material A feeding bin of the A bottle rises, while the liquid extraction needle and the gas needle assembly of the raw material A liquid extraction needle assembly do not move, causing the liquid extraction needle and the gas needle of the raw material A liquid extraction needle assembly to pierce into the A bottle. The gas needle is connected to a diaphragm pump through a hose and starts to blow air into the closed A bottle. The liquid extraction needle pierces to the bottom of the A bottle and is connected to the activation reaction device through a hose. Thus, raw material A enters the activation reaction device through the liquid extraction needle and the pipeline. The design of double needles piercing and pressurized extraction is adopted for extracting the liquid of raw material A. This design can ensure that the A liquid is in a fully sealed environment before extraction. During the extraction process, the pressurized gas can ensure the cleanliness of the gas source after filtration. The solution can be completely extracted without inverting the bottle body. The method of extracting raw material A is to apply gas pressure in a closed pipeline, so that the solution can enter the activation reaction kettle along the direction of the pressure pipeline.

[0073] The activation reactor 1 is on the exclusive platform on the right side of the lifting platform 42 and is connected to the entire movement core integrated platform through sheet metal and screws. The waste bin 2 is below the raw material A discharging motor 8. When the raw material A passes through the raw material A discharging motor 8, the A bottle can fall into the waste bin 2 by its own weight. The waste bin 2 is manually pluggable. After the waste bin is full, after the lifting door 3 descends, the waste bin 2 can be taken out and the used empty raw material A bottles can be emptied. The lifting door 3 is fixed to the outermost side of the movement core assembly through sheet metal and screws, and the lifting of the lifting door 3 is controlled by the lifting door 3 motor, lead screw and slide rail. The raw material A feeding bin 4, the raw material B burette 5, the lifting motor 6, the liquid taking valve assembly 7, and the raw material A discharging motor 8 are fixed to the movement platform by sheet metal and screws, and are in an overall up-and-down structure. The entire platform runs up and down driven by the lifting motor 6 and the lead screw 35. The container of raw material B, i.e., the B bottle, is located below the movement platform 42, and the container containing raw material B is driven by a robotic arm to rotate to the position where the raw material B burette extracts raw material B or the storage position of the container containing raw material B; there is also 1 motor and a robotic arm. The robotic arm is connected with a device for removing the lid of the container of raw material B, and the opening or closing of the lid of the container containing raw material B is controlled by the said lid removing device.

[0074] The raw material C rotating motor 10 makes the C bottle swing on a horizontal plane. It swings to the stirring position, or the outlet position, or the titration position. The B bottle and the C bottle swing on a plane, which is convenient for the B bottle and the C bottle to alternately rotate to the titration position during the preparation process. The B bottle rotates to the titration position to suck the raw material B, and the C bottle rotates to the titration position to drip the raw material B, which is convenient for the conversion of different working positions of the B bottle and the C bottle during the preparation process and realizes automatic control.

[0075] The stirring device is fixed to the movement core platform through screws. After the raw material C feeding control detects that there is raw material, after the upper computer confirms, the door is closed, and the program will issue an instruction to control the raw material C rotating motor 10 to rotate to the specified position for stirring or the titration position.

[0076] The integrated design and top-down layout of the above components can not only effectively reduce costs, but also promote the efficient and stable operation of the equipment and reduce the failure rate. For example, the raw material A feeding bin 4, the raw material B burette 5, the lifting motor 6, and the raw material A discharging motor 8 are integrated on a lifting platform 42, and one lifting motor 6 can be used to complete the process of titrating raw material B and inserting the needle into the raw material A bottle, reducing the investment of one motor and effectively reducing the cost and the equipment failure rate. For example, the top-down layout of the activation reactor 1, the raw material A discharging motor 8, the liquid taking valve assembly 7, the raw material B bottle, and the raw material C bottle can not only effectively reduce the length of the hose, save costs, but also effectively reduce the liquid retention in the hose during the liquid transportation process and improve the preparation accuracy.

[0077] The activation reactor 1 is used to activate raw material A. The activation reactor includes an activation reactor electrode drive plate unit, an activation reactor electrode, a liquid inlet / outlet unit, a gas inlet / outlet unit, and a liquid activation pool. The activation reactor electrode drive plate unit is located above the activation reactor electrode, and the liquid activation pool is located below the activation reactor electrode. The liquid activation pool and the activation reactor electrode form a sealed cavity. It also includes a cooling fan, an activation reactor housing, and a protection coil.

[0078] The material of the liquid activation pool is made of polytetrafluoroethylene. The air inlet, exhaust port, liquid discharge port, and liquid inlet are food-grade PP material tower heads, which are fastened to the liquid activation pool by threads. The activation reactor electrode drive plate unit includes an activation reactor electrode drive plate. The activation reactor electrode drive plate, activation reactor electrode, and liquid activation pool are fastened together by screws. The activation reactor housing covers the activation reactor electrode drive unit, activation reactor electrode, and liquid activation pool. There is a cooling fan on one side of the activation reactor housing, and cooling holes are provided on the device housing opposite the fan and on the other two sides. During the operation of the activation reactor, the fan works continuously to ensure sufficient heat dissipation during the operation of the activation reactor.

[0079] The liquid discharge port is placed at the bottom to ensure complete liquid discharge without residue.

[0080] Working principle and process: When feeding liquid, the liquid of raw material A enters from the liquid inlet. The air inlet and liquid discharge port are closed, and the exhaust port is opened. The liquid can enter the bottom inverted pyramid-shaped liquid activation pool. Then the activation reactor electrode drive plate unit drives the activation reactor electrode drive plate to discharge at high voltage for activation. After activation is completed, the air inlet and liquid discharge port are opened, and the exhaust port and liquid inlet are closed. The air pump is connected to the air inlet through a silica gel tube, and air is blown into the inverted pyramid-shaped liquid activation pool, and the liquid is discharged through the liquid discharge port. The raw material A solution is injected into bottle C after being activated in the activation reactor. The injection duration is set to 30 seconds. During the injection of the activated A liquid, the stirring device 11 is instructed to work simultaneously. The raw material B rotating motor 9 drives the raw material B cockpit to reset. After the injection of the activated A liquid into bottle C is completed, the raw material C rotating motor 10 is instructed to rotate to the titration position. The lifting motor drives the lead screw 35 to control the moving platform 42 to descend and stop above bottle C. At this time, the raw material B titrator 5 is directly opposite the mouth of bottle C. The program instructs the lifting motor to press down the push rod of the raw material B titrator 5 to drop the B liquid into bottle C.

[0081] The stirring device 11 includes a raw material C rotating motor 10, a bottle C, a robotic arm, a raw material C cockpit, a magnetic stirrer, and a rotating head with a permanent magnet. Bottle C represents the bottle for containing raw material C, which can be bottle-shaped or other shaped containers.

[0082] 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 stirrer in bottle C to rotate.

[0083] The motor of the stirring device 11 is connected to the rotating head, and a permanent magnet is arranged inside the rotating head. The stirring bar is arranged in bottle C.

[0084] Inside the stirring bar is a permanent magnet or magnetic material, and the outer layer is wrapped with polytetrafluoroethylene material, with a smooth or rough coating.

[0085] The position of the permanent magnet in the rotating head corresponds to that of the stirring bar. If the shape of the stirring bar is that of a long pill, the two permanent magnets are symmetrically arranged at 180 degrees. If the stirring bar is cross-shaped, one permanent magnet can be arranged every 90 degrees in the rotating head, with a total of 4 arranged. In short, the permanent magnet in the rotating head drives the stirring bar to rotate by magnetic attraction.

[0086] It also includes a feeding device for raw material C, which includes a rotating motor 10 for raw material C, an infrared photoelectric sensor, a lifting door 3, and a cockpit for raw material C.

[0087] The rotating motor 10 for raw material C is an industrial-grade standard servo motor, which is fixed on the component base platform through sheet metal. The motor and the base are fixed through sheet metal to cooperate with the loading and identification procedures of raw material C. The working process of feeding raw material C is as follows: on the upper computer operation interface, click the right-side loading C button, the lifting door 3 descends to the preset position, and the cockpit for raw material C is exposed (initial position). The RFID module is used to mark the coding traceability of the bottle of raw material C. Bring the bottle of raw material C close to the RFID module for identification to detect the bottle information and validity period of raw material C, and upload the detection and verification information to the cloud server. After passing the verification, put the bottle of raw material C into the cockpit for raw material C. When the infrared sensor detects the presence of the bottle of raw material C, the next program can be carried out. Click to close the hatch according to the prompt, and the lifting door 3 rises to the preset position. At this time, the feeding of raw material C is completed.

[0088] The rotating motor 10 for raw material C drives the cockpit for raw material C to automatically open at the exit. After putting the bottle of raw material C in, it rotates to the stirring position and the titration position, and automatically clamps the bottle of raw material C after leaving the exit.

[0089] The rotating motor 10 for raw material C is a power-providing mechanism. By controlling the cockpit for raw material C with the rotating motor 10 for raw material C, the device can fix or release the bottle of raw material C. By controlling the cockpit for raw material C with the rotating motor 10 for raw material C, the bottle of raw material C can be swung to the exit position of the bottle of raw material C, or the stirring position of the bottle of raw material C, or the titration position of the bottle of raw material C.

[0090] After the stirring is completed at the stirring position, the rotating motor 10 for raw material C controls the cockpit for raw material C to swing the bottle of raw material C to the exit position of the bottle of raw material C. The cockpit for raw material C on the robotic arm hits the limit stop, and the clamping force of the cockpit on the bottle becomes smaller, making the bottle in a relaxed state and ready to be taken out. After the tooth whitening gel is prepared, the lifting door 3 descends, and the bottle of raw material C containing the tooth whitening gel is taken out.

[0091] The presence of bottle C is detected by a liquid device vacancy detection sensor, and the position of bottle C is detected by a swing position sensor, so as to realize automatic control of bottle C for stirring. The principle of the sensor is not limited, and the sensor of the existing technology can be used to achieve it. After the activated aqueous solution of raw material A activated from the activation reaction kettle is injected into bottle C at the stirring position, after the activated water and raw material C are preliminarily stirred, bottle C is rotated to the titration position to drop the solution of raw material B, then rotated back to the stirring position to continue stirring, and finally taken out at the outlet position to use the prepared tooth whitening gel.

[0092] The raw material B titration device includes a push rod stroke sensor, an electric push rod, a moving platform, and a raw material titrator 5. The electric push rod drives the moving platform to raise or lower the titrator push rod, so as to suck the B solution from bottle B and then drop the B solution into bottle C. The push rod stroke sensor is used to detect the stroke of the electric push rod, so as to realize automatic control. The principle of the sensor is not limited, and the sensor of the existing technology can be used to achieve it. The raw material B titrator 5 is used to accurately set the volume of the titrated raw material B. The raw material titrator 5 can be provided with a separate moving platform for lifting and lowering, or can share a moving platform with the raw material A feeding bin 4.

[0093] The raw material B feeding device includes a raw material B rotating motor 9, a raw material B loading button, a robotic arm cockpit, and bottle B, where bottle B is the container containing raw material B. The raw material B rotating motor 9 holds bottle B through the robotic arm cockpit. The raw material B rotating motor 9 is used to control the swing position of bottle B, and swing bottle B to the titration position below the titrator and / or the storage position of bottle B according to the program setting. It also includes 1 motor, namely the raw material B cockpit cover motor, and the robotic arm. The robotic arm is connected with the container cover of raw material B, and the container cover of the container containing raw material B is opened or closed by controlling the robotic arm to lift or lower.

[0094] The raw material B rotating motor 9 and the cockpit cover motor are industrial-grade standard servos, which are fixed on the movement core frame 41 through sheet metal. The two motors are fixed through sheet metal and screws to cooperate with the operation of the raw material B loading program. The complete working process of loading raw material B is as follows: click the B loading button, the lifting motor 6 starts to rise to the preset position, the raw material B cockpit cover motor controls the robotic arm to lift the bottle cap of bottle B, the raw material B rotating motor 9 rotates clockwise by 90° to the titration position. At this time, put bottle B of raw material B into the robotic 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 counterclockwise by 90° to the storage position of bottle B, and the lifting motor 6 descends to the preset position. At this time, the loading of raw material B is completed.

[0095] The raw material B rotating motor 9 holds the B bottle through the robotic arm cockpit, removes the cap of the B bottle, swings the B bottle to the titration position below the raw material B burette 5. The raw material B burette 5 sucks the B solution, then moves the B bottle back to the storage position, puts on the cap. The raw material C rotating motor 10 swings the C bottle containing the preliminarily stirred activated water and C powder to the titration position below the raw material B burette 5, drips in the B solution. 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 tooth whitening gel is prepared. Each part of the device cooperates with each other to achieve the effect of non-contact and automated stirring of the liquid in a closed space.

[0096] As Figure 4 shown, the overall composition of a tooth whitening gel preparation machine includes a touch display screen 13, located in the upper front of the device, which is convenient for operation and used for human - machine interaction, starting the preparation of the tooth whitening gel and displaying the preparation status, showing the preparation time, and can also be used to test the preparation machine. The outer shell 14 is the protective shell of the tooth whitening gel preparation machine, used to protect the internal components of the device, with a beautiful appearance and convenient for operation and handling. The handle 15, drag handle 16 and as Figure 6 shown, the bottom wheels 23 facilitate the handling and moving of the tooth whitening gel preparation machine. The operation indicator light 17 is used to display the operation status of the device.

[0097] The upper - computer microcomputer is a platform for human - machine interaction and server interaction, and at the same time needs to send corresponding action instructions to the lower - computer electric control for execution. The lower - computer electric control is mainly for the preparation logic program control and signal detection and judgment.

[0098] As Figure 6 shown, the movement platform of the movement component assembly 18 includes all actuators, motors, and sensors assembled together, enabling the tooth whitening gel preparation machine to automatically prepare the tooth whitening gel. The actuators include liquid - gas valves and robotic arms. The power distribution control box 19 is located below the movement component assembly 18 and supplies power to each component of the device.

[0099] The liquid - taking valve assembly 7 is used to control the on - off of gas and liquid, and is a valve control module for switching the gas path and liquid path.

[0100] The liquid - taking valve assembly is on the upper part and the back of the device. The liquid - taking valve assembly is a general term for all valves. In this patent, when it is said to open or close the liquid - taking valve assembly, or when the liquid - taking valve assembly is involved somewhere, it all refers to opening or closing the valve corresponding to this step of the device or equipment.

[0101] The traditional liquid path and gas path both adopt the solenoid valve scheme. The solenoid valve has a short service life, a complex structure, is prone to problems, and will heat up or burn out when opened for a long time.

[0102] The servo-servo method adopted by the liquid extraction valve assembly of this patent application controls the series-connected valves through bus communication, with a simple circuit and easy maintenance. At the same time, the flow rate can also be controlled by controlling the angle of the valve. Since the mechanical rotation plus control angle servo-servo scheme is adopted, the valve switch can maintain a state for a long time, and there is no situation of overheating or even burning out due to long-term power-on. As Figure 7 、 Figure 8 shown, the servo-servo 20 installed on the bracket 21 controls the opening and closing of the control valve 22. The mechanical valve is completely isolated from the servo motor to prevent liquid from corroding the circuit components.

[0103] As Figure 9 shown, the liquid extraction valve assembly 7 controls the raw material A liquid extraction needle assembly 32 through the A-bottle liquid extraction air valve assembly 28 to make the raw material A in the A-bottle 31 enter the activation reactor device 24. After activation, the activation water is injected into the bottle 29 through the injection needle assembly 30 under the control of the activation reactor module exhaust valve assembly 26, the C-bottle injection liquid valve assembly 25, and the C-bottle injection air valve assembly 27.

[0104] Raw material A, raw material B, and raw material C respectively represent a raw material or a mixture of several raw materials.

[0105] Raw material A is a hydrogen peroxide solution with a concentration of 2.5%-6%, and the optimal one is 6%. It is canned in a vial sealed with a rubber stopper, that is, the A-bottle, and the volume of the A-bottle is 5 ml. Raw material B is a neutralizer, and the main component is a sodium hydroxide solution with a concentration of 10%. It is canned in a vial sealed with a rubber stopper, that is, the B-bottle, and the volume of the B-bottle is 8 ml. Raw material C is carbomer, with a mass of 0.02-0.08 g, and the optimal one for a single preparation is 0.04 g. Raw material C and the stir bar are placed in a vial, and the C-bottle is a vial. In the tooth whitening gel preparation machine of this patent, the distance that the motor drives the lifting platform has good repeatability. There will be a fixed liquid residue in the A-bottle. During a single preparation process, 3 ml of raw material A is used, approximately 0.2 ml of A liquid remains, about 0.2 ml of raw material B, and 0.04 g of raw material C. An activation time of 5-10 minutes is required, and the optimal one is 7 or 8 minutes, at which time the performance of the activation water reaches a stable state. The volume ratio of the hydrogen peroxide solution to the neutralizer is 15:1, and this ratio has just the right consistency, can adhere to the teeth, and has a moderate pH. The stirring time is generally 5-10 minutes.

[0106] Ratio 1: 3.2 ml of hydrogen peroxide solution with a concentration of 2.5%, 0.2 ml of neutralizer with the main component being 10% sodium hydroxide solution, and 0.02 g of carbomer.

[0107] Ratio 2: 3.2 ml of hydrogen peroxide solution with a concentration of 3%, 0.2 ml of neutralizer with the main component being 10% sodium hydroxide solution, and 0.04 g of carbomer.

[0108] Ratio 3: 3.2 ml of 6% hydrogen peroxide solution, 0.2 ml of a neutralizing agent which is mainly 10% sodium hydroxide solution, and 0.08 g of carbomer.

[0109] The tooth whitening gels prepared from the above three ratios by the tooth whitening gel preparation mechanism of the present application can be directly coated on the tooth surface, and the effect differences are not significant. The effect of Ratio 3 is the best. It does not require a gum protector, has a definite tooth whitening effect, and can greatly reduce the risks of common allergies and post-whitening soreness caused by high-concentration hydrogen peroxide gels.

[0110] Clinical results show that the whitening gels and whitening liquids prepared using the device of the present invention are non-toxic, non-irritating, and odorless. There is no residual gel after rinsing after whitening, and they have a good tooth whitening effect.

[0111] The tooth whitening effect can be adjusted by adjusting the concentration of hydrogen peroxide solution in Raw Material A, the activation time of the activation reaction kettle, the thickness of the gel coated on the teeth, and the time for the gel to act on tooth whitening.

[0112] The 40 subjects participating in the clinical trial had yellow teeth with ordinary exogenous staining. They were divided into 2 groups for testing, with 20 people in each group. The experimental group used the tooth whitening gel prepared from Formula 2 and this device. The control group used 3 ml of ultrapure water to replace the activated Raw Material A, the neutralizing agent was 0.2 ml of 10% sodium hydroxide solution, and 0.04 g of carbomer, and the gel was prepared manually.

[0113] The whitening method was to coat the gel on the tooth surface in 3 times for each person, with each whitening time being 15 minutes. During the process, a cold light lamp was used for catalytic stimulation, and the total action time was 45 minutes. None of the subjects used a gum protector before whitening and a desensitizer after whitening.

[0114] The whitening effect was mainly judged and analyzed using the VITA Bleachedguide 3D-Master colorimetric plate, which is a commonly used intuitive visual effect analysis method in clinical practice.

[0115] The color of the teeth is determined by three values: brightness, color saturation, and color value through color comparison with the colorimetric plate (here, the Vita colorimetric plate is used as an example). The M column is the intermediate color, the L column is more yellow, and the R column is more red. First, compare the brightness horizontally. Find the group with the highest brightness from dark to light among the 5 groups of 1, 2, 3, 4, and 5. Second, compare the saturation vertically and find the one with the best saturation. Then compare the color value horizontally.

[0116] The tooth whitening gel prepared by this device has an excellent whitening effect. The color difference ΔE of the teeth before and after whitening can be 3 to 8 color levels, and none of the participating subjects had a sense of soreness after the operation.

[0117] The control group followed the same gel application and colorimetric method, and the difference in tooth shade ΔE before and after whitening increased by nearly 0 shade.

[0118] Statistical analysis software was used to perform statistical analysis on the experimental results. The results were expressed as: mean ± standard deviation, and a normal distribution test was conducted. An independent samples t-test or Wilcoxon rank sum test was used to compare 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 shade ΔE before and after whitening in the sample group was 3.90 ± 1.14. The difference in tooth shade ΔE before and after whitening in the control group was 0.00 ± 0.00. There was a very significant difference in the shade change after using the product between the sample group and the control group (P < 0.01), indicating that there was a very significant difference in the effect of the tooth whitening gel prepared by this device compared with the control group.

[0120] A method for preparing a tooth whitening gel. By clicking the automatic start button on the touch display screen 13, the programmed lifting door 3 starts to descend. The raw material C rotating motor 10 controls the robotic arm to work to the outlet. After the action is completed, an instruction is returned to the touch display screen 13 to indicate that it can be loaded. After loading is completed, click the touch display screen 13 to confirm the placement of bottle C, and at the same time, the device detects whether bottle C is placed. Bottle C is a container containing raw material C and a stir bar. After detecting successful placement, the production date is recorded and the expiration date is set. The lifting door 3 is controlled to start rising and the hatch is closed. Enter the password to start sending instructions to initiate the preparation.

[0121] As Figure 10 shown, at the beginning of the preparation, the raw material A discharging motor 8 drives the A bottle feeding dial 12 to rotate, and transports the raw material A in the raw material A upper storage bin 4 to the designated position, that is, the raw material A extraction and feeding position. The waste A bottle after extraction is discarded into the A bottle waste bin 2. The A bottle waste bin 2 collects the containers from which raw material A has been extracted. After this action is completed, the lifting motor 6 starts to rise and enters the extraction position. The valve is opened, and raw material A is extracted under pressure into the activation reaction kettle 1. When the liquid is completely extracted, the activation reaction kettle 1 is started to work with power on, and the lifting motor 6 starts to descend. At this time, the raw material C rotating motor 10 runs bottle C to the filling position through the robotic arm. The filling position and the stirring position are the same position. The raw material B rotating motor 9 runs bottle B to the titration position through the robotic arm, and the raw material B titrator 5 sucks raw material B and waits for titration. Bottle B is a container containing raw material B.

[0122] After the activation reactor 1 is activated, open the valve to pressurize and fill the started raw material tank into the container of raw material C, that is, the C bottle. Start the magnetic stirring of the stirring device 11. After the filling is completed, the lifting motor 6 starts to drive the raw material B burette 5 to rise. The raw material B rotating motor 9 runs the B bottle to the storage position through the robotic arm. The raw material C rotating motor 10 runs the C bottle to the titration position through the robotic arm. The raw material B burette 5 titrates the aspirated raw material B into the C bottle after filling. After the titration is completed, the raw material C rotating motor 10 runs the C bottle to the stirring position through the robotic arm, and continues magnetic stirring to complete the preparation.

[0123] After the preparation is completed, the touch display screen 13 shows that the countdown ends, indicating completion. Click the button to open the hatch, and control the lifting door 3 to start descending. The raw material C rotating motor 10 transports the C bottle to the outlet through the robotic arm. Then the finished product can be taken. After confirming the removal, the lifting door 3 starts to rise to close the hatch.
