Description
Technical field
The present invention relates to toothbrush art, and in particular to a kind of dual drive ultrasonic toothbrush
Background technology
Ultrasonic toothbrush is exactly the high frequency vibrating dynamic formula electric toothbrush that vibration frequency reaches ultrasonic frequency.According to ultrasonic wave
Define, the vibration frequency of ultrasonic toothbrush should reach at least 20,000 hertz.Ultrasonic toothbrush is after ordinary toothbrush, electric tooth
Forth generation novel toothbrush after brush, acoustic toothbrush.The high frequency sound wave that ultrasonic toothbrush uses, produce water postcritical " empty
Change " phenomenon, reach the effect for cleaning tooth and oral cavity.Ultrasonic wave not only can directly kill bacterium, block the formation of bacterial plaque,
Dental surface and hiding tartar and tooth stain can also be rinsed by the high energy species of cavitation, reach the effect of cleaning one's teeth shield tooth.
Electric toothbrush in the market is all to reach increase vibration plus eccentric wheel as vibration source using direct current generator
The effect of amplitude, the result is that whole toothbrush is all vibrating including handle portion, the experience of user and effect are all very poor；It is and straight
It is too low to flow vibration frequency caused by motor rotation, much smaller than the vibration frequency of ultrasound, does not have the effect of ultrasonic deep layer cleaning.Have
Built-in a piece of piezoelectric patches produces ultrasonic vibration in indivedual external high-end brush for electric toothbrush, but because piezoelectric patches is made in itself
Too small for amplitude caused by vibration source, these Weak Ultrasonics do not have the effect of ultrasonic deep layer cleaning substantially.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of solution method, can be complete
The dual drive ultrasonic toothbrush that orientation deep layer cleans the teeth.
The purpose of the present invention can be achieved through the following technical solutions：A kind of dual drive ultrasonic toothbrush, including outside
Structure and internal structure, wherein external structure include brush, brush holder and handle, and described brush connects handle by brush holder, its
It is characterised by, described internal structure includes ultrasonic transducer, direct current generator, driving plate, described ultrasonic transducer, direct current
Mechanism connects brush, described driving partitioned signal connection ultrasonic transducer and direct current generator respectively into dual drive；
Described driving plate produces the electric signal that dual drive needs, and direct current generator produces low-frequency vibration, ultrasonic transducer production
Raw dither, the vibrations of two kinds of frequency ranges work or are superimposed respectively work, carry out deep layer and comprehensive cleaning tooth.
Described ultrasonic transducer includes front shroud, piezoelectric patches, back shroud and bolt, and described back shroud and bolt are pressure
Electric piece is fixed on front shroud, and to the pretightning force required for piezoelectric patches, the amplification ultrasonic vibration of described front shroud and vibration
Pass to the brush of toothbrush.
Retainer ring and node are provided among described front shroud, described front shroud is fixed on the outer of toothbrush by retainer ring
On shell, described retainer ring is connected on the node of front shroud.
Described retainer ring one end and the node integrated setting, the other end on the inside of toothbrush body with being fixedly connected.
Described protecgulum front edge of board is placed in brush, and rear end connection piezoelectric patches, described piezoelectric patches and back shroud are placed in brush
In handle.
Described front shroud and the material of back shroud are light metal material, including aluminium or aluminium alloy.
Described ultrasonic transducer has one or more resonant frequencies.
Described ultrasonic transducer may be used as sensor, be arrived the tooth data transfer of user by wireless transmission method
In application program, it is used for self-examination after program is analyzed and dentist diagnoses.
Described direct current generator includes eccentric wheel and fixed support, and described eccentric wheel is fixed on brush holder by fixed support
Interior, caused vibration hair greatly and is passed to brush by described eccentric wheel by brush holder.
The brush of described external structure is provided with bristle, or other professional tooth tool heads, adds rubber on described handle
Glue, shake and increase the comfortableness held with further reduce；Described internal structure is additionally provided with rechargeable battery and wireless charging
Coil, described rechargeable battery connection driving plate, there is provided the energy required for driving plate, the connection of described Wireless charging coil are filled
Battery, periodically to rechargeable battery with contactless charging.
The dual drive structure that described ultrasonic transducer is formed with direct current generator may be also used in other individual consumer's goods or
In domestic consumer product.Such as Household floor-sweeping machine device people, ultrasonic wave face washing instrument etc..
The present invention is using ultrasonic transducer as driving so as to reaching ultrasonic vibration truly come to tooth and mouth
Chamber carries out deep layer cleaning.The working frequency and operation mode of ultrasonic transducer can be designed with required for generation as needed
Dither carry out deep layer cleaning, while also with direct current generator plus eccentric wheel produce low-frequency vibration carry out secondary, this
Sample can realize low-frequency vibration and dither while occur, and reach the purpose of comprehensive cleaning.
The present invention proposes the structure design of new type ultrasonic toothbrush, including two drivings.Produced by traditional direct current generator
The vibration of two kinds of frequency ranges of dither required for giving birth to common low-frequency vibration and being produced by ultrasonic transducer is superimposed, and reaches
To deep layer and the purpose of comprehensive cleaning tooth.The critical piece of ultrasonic transducer is piezoelectric patches, but piezoelectric patches produces in itself
Vibration it is very faint, if only by the use of piezoelectric patches as vibration source if do not have the effect brushed teeth of ultrasound.Ultrasonic transducer is profit
It is operated with system resonance mode, by front shroud, piezoelectric patches, bolt and the specially designed resonance mode of back shroud in electricity
It can be resonated in the presence of signal, thus the vibration exported is more much bigger than single piezoelectric patches, can be used for cleaning tooth.
Meanwhile ultrasonic transducer as driver while, can also be used as sensor, the respective data transfer of tooth to should
With in program, such user's can knows the situation of oneself tooth in time.
Compared with prior art, beneficial effects of the present invention are embodied in following several respects：
First, it is easy to operate：Ordinary toothbrush needs people that bristle firmly is coordinated into toothpaste, and friction reaches cleaning repeatedly on tooth
The purpose of dental surface.Toothbrush of the present invention can realize automatic teeth-brushing, bristle need to only be moved on to relevant position without firmly can
Reach the purpose of cleaning tooth.
2nd, work well：Ordinary toothbrush have no idea to remove bristle less than place clean.The toothbrush production of the present invention
Raw vibration bristle can also be gone less than place clean, while also have cleaning effect to oral cavity.
3rd, Consumer's Experience is good：If the ordinary toothbrush firmly excessive phenomenon for easily causing bleeding gums.The invention is to gum
Do not injure, and need not be exerted oneself substantially during brushing teeth, a brand-new and happy experience of brushing teeth is brought to user, for
The health at family is also very helpful.
