Acoustic toothbrush with whitening and antiseptic function {ELECTROMOTIVE TOOTH BRUSH WITH WHITENING AND STERILIZING FUNCTION}

The present invention relates to a sonic electric toothbrush having a whitening and sterilizing function, and more particularly, to clean the teeth while vibrating in the sonic range to improve the cleanliness of the teeth, and to perform the sterilization of the teeth and bristles by the beneficial light beam. The present invention relates to a sonic electric toothbrush having a whitening and sterilizing function that can be replaced individually in the event of wear or failure.

In general, the toothbrush is most widely used as a hygiene tool for maintaining the cleanliness of the inside of the mouth and teeth along with the dental floss. Such a toothbrush is used in a variety of types depending on the age of the user or the state of the tooth, but after brushing the toothbrushes and various bacteria remain in the tooth damage to the dental health it is necessary to disinfect to remove it.

To disinfect toothbrushes using chemicals or disinfection equipment, each time a separate medicine or disinfection equipment must be provided, which is very cumbersome and inconvenient to use. Accordingly, in recent years, a toothbrush such as Korean Utility Model Registration Application No. 20-2003-0001664 has been devised so that the sterilization apparatus is configured on the toothbrush itself and used conveniently.

Such a toothbrush is configured to perform a sterilization effect by ultraviolet light emitted by the operation of the switch, the ultraviolet lamp is configured to emit light by using a coin-type battery as a power source.

However, the conventional sterilized toothbrush as described above has the effect of improving hygiene by disinfecting the brush head by ultraviolet rays, but it is impossible to replace the toothbrush when damaged or worn, or when the UV lamp breaks, so the entire toothbrush should be discarded. Its disadvantage is that it is relatively short in terms of time and wastes of resources.

In addition, the conventional sterilized toothbrush is to brush the teeth because it is performed depending on the manual operation of the user is difficult to brush the teeth, cleaning of the teeth is very low cleanliness and teeth whitening could not be performed at all.

In addition, in order to maintain the health of the teeth, the state of health of the gum supporting the teeth is very important, but the conventional sterilized toothbrush has no other way to maintain or improve the health of the gums.

Hereinafter, a driving method of a sound wave electric toothbrush having a whitening and sterilizing function according to an embodiment of the present invention will be described.

Figure 6 is a flow chart illustrating a method of driving a sound wave electric toothbrush having a whitening and sterilizing function according to the present invention.

First, in order to apply the method of driving a sonic electric toothbrush having a whitening and sterilizing function according to the present invention, at least the sonic electric toothbrush as described above has a vibration generating means, a lamp, an input unit, a control unit, and a power supply unit having a rechargeable battery and a charging module. It should be provided.

Referring to FIG. 6, the driving method of the sound wave electric toothbrush having the whitening and sterilizing function according to the present invention will be described in detail. When the user presses the input unit 40, the control unit 60 inputs the first input from the input unit. A first driving step S1 of determining whether or not a signal is input (S11) and controlling the vibration generating means 30 to be driven (S12) for a predetermined time when the first input signal is input is performed.

According to this, the first driving step (S1), the vibration of the sound wave frequency range generated by the drive of the vibration generating means 30 is transmitted to the bristles 81 through the head portion (20). In this state, the bristles may be brought into contact with the teeth to perform the cleaning action of the teeth. At this time, the driving time of the vibration generating means 30 is preferably about 3 minutes.

During the execution of the first driving step S1 described above, the controller 60 determines whether the second input signal is input from the input unit (S21), and when the second input signal is input (the user presses the input unit 40 again). The second driving step S2 is performed to control the lamp 70 to be driven S22 for a predetermined time together with the vibration generating means 30 that is already driven.

According to the second driving step S2, the lamp 70 is driven to irradiate light with the cleaning action of the teeth according to the driving of the vibration generating means 30, and thus, due to the ultraviolet light emitted from the UV-diode. Sterilization of the teeth and oral cavity and whitening of the teeth are performed, and the gums are stimulated by the laser beam irradiated from the laser diode and heat flow can be increased, thereby improving the health of the gums. At this time, the driving time of the vibration generating means 30 is preferably about 3 minutes before and after adding the driving time of the first step, and the driving time of the lamp 70 is also preferably about 3 minutes.

Then, during the execution of the second driving step S2, the controller determines whether the third input signal is input from the input unit (S31), and when the third input signal is input (the user presses the input unit 40 again on the pressing operation). The driving of the vibration generating means 30, which is being driven), is first blocked (S32), and then the third driving step (S3) of controlling the driving of the lamp is blocked (S33) after the set time elapses. .

According to the third driving step S3, when the user performs a pressing operation to stop brushing teeth during the execution of the second driving step S2, the driving of the vibration generating means 30 is stopped and the brushing of the teeth is stopped. When the lamp 70 is completed for a predetermined time, the bristles 81 are sterilized. At this time, the lighting time of the lamp is preferably about 3 minutes or so. In addition, when the lamp 70 is emitted and ultraviolet rays are irradiated to the bristle side, the photocatalytic action of titanium dioxide contained in the bristles enables more effective sterilization.

On the other hand, in the driving process of the second driving step (S2) and the third driving step (S3) described above, it is determined whether or not charging is performed by the charging module in the rechargeable battery (S41), and when charging is performed, the lamp 70 is performed. Since the fourth driving step (S4) to control to be shut off after being driven for a set time (S42) is performed, it is possible to always maintain the sound wave electric toothbrush sterilized.

According to the fourth driving step (S4), as shown in FIG. 4, when the user completes the use of the sonic electric toothbrush and places the sonic electric toothbrush on the charger body 110 for charging or storage, the controller ( The lamp 70 emits light by the auxiliary sterilization control circuit provided at 60 to finally perform sterilization.

As described above, the sound wave electric toothbrush having a whitening and sterilizing function according to a preferred embodiment of the present invention is shown in accordance with the above description and drawings, but this is only an example and is not limited to the scope of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made therein.
