Description

Technical Field

[0001] The present invention relates to the field of dental care, and particularly to a dual-mode dental care device. Background Art

[0002] Teeth are one of the very important organs of humans, and protecting teeth is a very important matter in people's daily lives. One is to keep teeth clean, reduce tooth-related diseases, and extend the lifespan of teeth; the other is the tooth exercise advocated by traditional Chinese medicine, such as tapping, through active tooth tapping vibration, to achieve the purpose of strengthening teeth and improving health levels.

[0003] Regarding tooth cleaning, Chinese Patent Application No. 201922304989.6 discloses a new type of ultrasonic tooth cleaning device, which includes a tool head and an ultrasonic transducer fixedly connected to the tool head. The ultrasonic transducer includes an intermediate plate, and at least one piezoelectric ceramic sheet is provided on the intermediate plate. The tool head is connected with a detachable toothbrush head or a tooth cleaning head, and the vibration frequency range of the ultrasonic transducer is between 10 kHz and 100 kHz. Through the above settings, the installation and use of the toothbrush head and the tooth cleaning head can be used simultaneously. Using the mature piezoelectric ceramic double wafer structure as the ultrasonic transducer, the vibration frequency is maintained between 10 kHz and 100 kHz to ensure good tooth cleaning effect. However, in the above prior art, only the toothbrush head or the tooth cleaning head acts on the teeth to achieve ultrasonic tooth cleaning.

[0004] Currently, there is no related dental care auxiliary tool for traditional Chinese medicine tooth tapping.

[0005] It can be seen that the dental care devices in the above prior art obviously still have inconveniences and defects in structure, method and use, and need to be further improved urgently. How to create a dual-mode dental care device with both traditional Chinese medicine tooth tapping and ultrasonic cleaning functions has become an extremely urgent improvement goal in the current industry. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a dual-mode dental care device with both traditional Chinese medicine tooth tapping and ultrasonic cleaning functions, so as to overcome the deficiencies of the prior art.

[0007] To solve the above technical problem, the present invention adopts the following technical solutions:

[0008] A dual-mode dental care device includes an array transducer and a drive controller;

[0009] The array transducer includes a bottom negative metal substrate, on which a plurality of piezoelectric ceramic sheets are attached. A positive electrode is attached to each piezoelectric ceramic sheet, and a flexible insulating board is laminated on the plurality of positive electrodes. Positive electrode leads are built into the flexible insulating board. The overall shape of the array transducer is a U-shaped similar to the tooth arrangement shape. The plurality of piezoelectric ceramic sheets correspond one by one to the tooth mark distribution positions of the upper and lower rows of teeth.

[0010] The drive controller is connected to the array transducer. The drive controller is provided with a traditional Chinese medicine tooth tapping function mode controlled by a pulse signal and a cleaning function mode controlled by an ultrasonic signal, which is used to convert the voltage change applied between the positive and negative electrodes into the thickness change of the piezoelectric ceramic sheet, so as to control the array transducer to perform traditional Chinese medicine tooth tapping or ultrasonic cleaning from the tooth top surface.

[0011] As a further improvement of the present invention, it further includes a device type parameter acquisition template. The device type parameter acquisition template adopts a U-shaped similar to the tooth arrangement shape for collecting the tooth marks of the upper and lower rows of teeth of a person to determine the tooth force point distribution pattern. The plurality of piezoelectric ceramic sheets correspond one by one to the tooth mark distribution positions of the upper and lower rows of teeth collected by the device type parameter acquisition template. This is used as the customization basis for the user's tooth shape structure.

[0014] Further, according to the human oral cavity size, the device type parameter acquisition template is divided into three templates: large, medium, and small.

[0015] Further, the positive electrode leads of each positive electrode of the array transducer are grouped and connected. Each group of leads is bundled and connected to a connector through a group of wires, and is connected to the drive controller through the connector. The drive controller can control the drive signal to be applied to different wires to achieve separate drive control of each group of teeth.

[0016] Further, the positive electrode lead grouping is grouped by tooth area (for example, divided into five groups).

[0017] Further, the drive controller includes a power supply, a signal source, a signal controller, a power amplifier, and a control panel.

[0018] The signal source includes a pulse signal source and an ultrasonic signal source.

[0019] The signal controller is respectively connected to the power supply, the signal source, the power amplifier, and the control panel.

[0020] Further, function selection buttons, signal strength selection knobs, and mode selection buttons are provided on the control panel;

[0021] The function selection buttons include a traditional Chinese medicine teeth clenching function selection button and a cleaning function selection button;

[0022] The selection parameter of the signal strength knob is the signal voltage, and the thickness of the piezoelectric ceramic sheet is controlled by the signal voltage, thereby regulating the strength;

[0023] Among the mode selection buttons, the selectable parameters corresponding to the traditional Chinese medicine teeth clenching function include: pulse width, pulse repetition frequency, grouping method, grouping order, teeth clenching duration, and teeth clenching repetition times; the selectable parameters corresponding to the cleaning function include: cleaning frequency and cleaning duration.

[0024] Further, the grouping method includes grouping into five groups, three groups, two groups, and no grouping.

Detailed implementation manners

[0040] Hereinafter, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present invention can be more thoroughly understood and the scope of the present invention can be completely conveyed to those skilled in the art.

[0041] The present invention draws on the idea of traditional Chinese medicine's tooth knocking and introduces the technical idea of ultrasonic cleaning, combines the two, and develops a brand-new tooth auxiliary care device: a dual-mode tooth protection. It should be noted that the above combination idea of the present invention belongs to a brand-new research direction.

[0042] A dual-mode tooth care device in this embodiment, as Figure 1 shown, includes an array transducer 1 and a drive controller 2 connected thereto. The two can be connected through a connector 3, and the connector 3 can adopt a plug-and-socket connection method, such as using a plug on the side of the array transducer 1 and a socket on the side of the drive controller 2.

[0043] Combined Figure 2As shown, the array transducer 1 includes a bottom negative metal substrate 11, on which a plurality of piezoelectric ceramic sheets 12 are mounted, each piezoelectric ceramic sheet 12 is attached with a positive electrode 13, and each positive electrode 13 is connected with a positive electrode lead; a layer of flexible insulating board 14 is compounded on the plurality of positive electrodes 13, and the positive electrode lead connected with each positive electrode 13 is built into the flexible insulating board 14. Since the positive electrode lead is in a sealed environment, short circuit caused by moisture in the oral cavity can be avoided. Figure 2 , 3 As shown, the overall shape of the array transducer 1 is a U-shape corresponding to the shape of the teeth arrangement; the multiple piezoelectric ceramic sheets 12 correspond one-to-one to the tooth mark distribution positions of the upper and lower rows of teeth (upper teeth 100, lower teeth 200).

[0044] The array transducer 1 mainly adopts the piezoelectric transducer pressure forming technology, combined with Figure 3 As shown, the voltage / thickness conversion principle of the material is utilized to process positive and negative electrodes (corresponding to the aforementioned positive electrode 13 and the bottom negative metal substrate 11, respectively) on the piezoelectric ceramic sheet 12. When a signal is applied and the required power is reached, the thickness of the piezoelectric ceramic sheet 12 increases, and when the signal stops, the thickness is restored, thereby applying a pulse or continuous wave ultrasonic signal to achieve the impact / vibration force on the corresponding teeth. Applying a signal according to the rhythm of tooth tapping produces the effect of traditional Chinese medicine tooth tapping, and vibrating at the ultrasonic frequency produces an ultrasonic descaling effect. Therefore, corresponding to each tooth stress point, a piezoelectric ceramic sheet 12 is installed and integrated on a common rigid plate, forming a transducer lattice, which is called an array transducer.

[0045] From the above principle, it can be known that the array transducer 1 can be connected through the driving controller 2; the driving controller 2 is provided with a traditional Chinese medicine tooth tapping function mode controlled by a pulse signal and a cleaning function mode controlled by an ultrasonic signal. By converting the voltage change applied between the positive and negative electrodes into the thickness change of the piezoelectric ceramic sheet 12, the array transducer 1 can be controlled to perform traditional Chinese medicine tooth tapping or ultrasonic cleaning from the top surface of the teeth.

[0046] In order to reduce the number of positive leads and ease the difficulty of the manufacturing process, the teeth are preferably divided into n groups (generally n is selected as 5) according to the region. The positive leads of the piezoelectric ceramic sheets 12 corresponding to each group of teeth are connected in groups, and each group of leads is bundled with a group of wires inserted into the socket through a plug and then connected to the drive controller 2. When in use, the drive controller 2 can control the drive signal to be added to different wires, so that different tooth movements can be corresponded, and the drive control of each group of teeth can be realized separately.

[0047] The array transducer 1 is designed based on the collected distribution pattern of the tooth force points.

[0048] Since the oral shapes, sizes, and tooth arrangements of each person are inconsistent and vary greatly, and both tapping and ultrasonic treatment require accurately applying energy to the top surfaces of the teeth, it is necessary to manufacture different shapes according to individual differences. Therefore, in this embodiment, a shape parameter acquisition template is used to collect the tooth shape layout, which serves as the basis for manufacturing a dual-mode tooth health care device. According to the distribution of human oral sizes, the shape parameter acquisition template is provided in three sizes: large, medium, and small, for users to select and complete the measurement.

[0049] Cooperate with Figure 5 As shown, the shape parameter acquisition template 4 is made of cardboard. The shape of the cardboard is a U-shaped plate corresponding to the tooth arrangement shape, mainly used to collect the tooth marks of the upper and lower rows of teeth of a person. Since the cardboard has a certain hardness and can maintain its shape unchanged, and has a certain flexibility to ensure that it can be marked with a pen for taking pictures after clearly leaving tooth marks. Graphic symbols are printed on the cardboard of the shape parameter acquisition template 4, such as upper and lower surface identifiers 41 (which can be marked with text characters such as "upper" and "lower"); additionally, as a preferred method, multiple marked points 42 with a specific layout (usually four can be selected) are printed on the upper and lower surfaces of the cardboard, which support correct processing and photo error correction when uploading the photo to the manufacturing enterprise. The positions of the black dots in the figure represent the tooth mark positions 43.

[0050] When in use, the user selects a shape parameter acquisition template 4 of an appropriate size. After confirming the correct upper and lower surfaces, put it into the oral cavity to match the tooth arrangement, bite down hard so that the top of the teeth leave tooth marks on the template. Take out the template, immediately use a non-fading standard pen such as a fountain pen or ballpoint pen to accurately mark the positions of the tooth marks, and use equipment such as a mobile phone to take pictures of the front and back sides and upload them to the manufacturing enterprise as technical documents and manufacturing basis for ordering.

[0051] The manufacturing enterprise corrects the photo error according to the marked points 42 in the figure to form a correct 1:1 graphic, and then produces an array transducer product that accurately corresponds to the user's teeth based on this. The correction principle is that after all four marked points 42 on the template taken by the user are registered and aligned with the standard graphic in the memory of the manufacturing enterprise, the error can be controlled within the permitted range. Assembling the transducer array according to the tooth mark positions in this figure can ensure that the transducers correspond one by one to the tooth stress points.

[0052] Cooperate with Figure 6 As shown, the drive controller includes a power supply (battery), a signal source, a signal controller, a power amplifier, and a control panel; the signal source includes a pulse signal source and an ultrasonic signal source; the signal controller is respectively connected to the power supply, the signal source, the power amplifier, and the control panel.

[0053] Function selection buttons, signal intensity selection knobs, and mode selection buttons are provided on the control panel; the function selection buttons include a traditional Chinese medicine tapping function selection button and a cleaning function selection button;

[0054] The selection parameter of the signal intensity knob is the signal voltage. The thickness of the piezoelectric ceramic sheet is controlled by the signal voltage, thereby regulating the intensity. Among them, the signal intensity (output intensity) refers to the magnitude of the impact force on the teeth, which is specifically reflected in the increased value of the thickness of the piezoelectric ceramic sheet under the action of the signal (denoted by Δd). The thickness of the piezoelectric ceramic sheet is d, and the signal voltage is u.

[0055] Increased value of thickness: Δd = f(d, u)

[0056] d = d1: (d1 is the thickness without signal)

[0057] d = d2: (d2 is the thickness when signal is applied)

[0058] Δd = d2 - d1

[0059] Among them, the selection parameter is the signal voltage u, (unit: volt).

[0060] For different materials, the functional relationship is different, but for each material, the functional relationship is determined and unchanged. The product manufacturer designs the adjustment ranges of parameters d and u according to the characteristics of the selected material. d is a fixed value, and the selection of u is controlled by the controller panel of the drive controller, so as to achieve the selection of the output intensity.

[0061] Among the mode selection buttons, the traditional Chinese medicine teeth clenching function corresponds to a pulse signal. The selectable parameters corresponding to the traditional Chinese medicine teeth clenching function include: pulse width t (unit: second), pulse repetition frequency f (unit: hertz), grouping method A - D (A: divided into five groups; B: divided into three groups; C: divided into two groups; D: not grouped), grouping order, teeth clenching duration T (unit: minute), teeth clenching repetition times n; this group of parameters is optimized by the user during use, and it is advisable to select the state that feels comfortable to oneself.

[0062] The cleaning function corresponds to an ultrasonic signal. The selectable parameters include: cleaning frequency F (unit: hertz), cleaning duration T 0 (unit: minute). Set the adjustment range of the frequency, adjust the frequency with the knob on the panel, and the user can select the frequency value that feels comfortable.

[0063] When the above dual - mode teeth health care device is in use, before starting up, the array transducer 1 and the drive controller 2 are interconnected through a plug - socket. After starting up, use the function selection button to select the function, that is, select the signal to be used, corresponding to the selected function; use the signal intensity selection knob to select the clenching or cleaning intensity. The mode selection button is used to select how to group, working sequence, duration, interval time, working time, etc. After selection, the teeth clenching or teeth cleaning function can be completed. After the teeth cleaning function is completed, rinsing the mouth with a commercial general mouthwash can achieve the purpose of protecting teeth.

[0064] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Any simple modifications, equivalent changes or decorations made by those skilled in the art using the above-disclosed technical content all fall within the protection scope of the present invention.
