Description

Electric toothbrush with two-gear vibration frequency

Technical Field

The utility model relates to an electric toothbrush technical field, in particular to electric toothbrush with two grades of vibration frequency.

Background

In modern life, toothbrushes are a necessity for cleaning the oral cavity of people. With the development and progress of science and technology, people invent the electric toothbrush, and a new tooth brushing mode enters the life of people. Electric toothbrushes are increasingly favored by people because of their scientific and effective design, which can remove dental plaque and reduce oral diseases such as gingivitis and gingival bleeding.

The existing electric toothbrush mainly uses a vibration principle as a main part, and through the quick rotation or vibration of a motor core, the bristles generate high-frequency vibration to decompose toothpaste into fine foam, so that parts which are difficult to clean, such as tooth slits and the like, can be effectively cleaned. However, the existing electric toothbrush is only provided with one vibration frequency, the oral cavity environment is variable, the residual stains of food and the like attached to teeth are difficult to remove, the low-frequency electric toothbrush is difficult to achieve the cleaning effect, and the high-frequency electric toothbrush can remove the stubborn residual stains, but can cause damage to the teeth and gum after long-term use. Meanwhile, the frequency and the strength of the electric toothbrush are fixed, children are easy to damage young and tender gingiva when using the electric toothbrush, so that the gingiva has symptoms such as redness and swelling, teeth can be severely abraded, and serious people can cause periodontitis to cause tooth shedding.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide an electric toothbrush with two vibration frequencies, which can switch the vibration frequency of a brush head.

The above technical purpose of the present invention can be achieved by the following technical solutions: the utility model provides an electric toothbrush with two grades of vibration frequencies, includes casing, base and installs in switch, power, miniature DC motor and the brush head of base, the base be located the casing, on-off control power and miniature DC motor between supply circuit's break-make, the brush head vibrate under miniature DC motor's drive, supply circuit be located the part between switch and the motor as the frequency modulation branch of deciding, still include with the frequency modulation branch of deciding to form parallelly connected frequency modulation branch, the frequency modulation branch on be provided with the diode, the switch be two way switch, two way switch with the frequency modulation branch and decide frequency branch and supply circuit switch connection.

By adopting the technical scheme, the two-gear vibration frequency of the miniature direct current motor is switched by the bidirectional switch and the fixed frequency branch and the frequency modulation branch.

Further setting the following steps: the bidirectional switch is a touch switch, the shell is provided with an operating part, and the operating part is matched with the touch switch to realize the switching connection of the frequency modulation branch and the fixed frequency branch with the power supply circuit.

Further setting the following steps: the operating piece is a soft rubber button.

Through adopting above-mentioned technical scheme, through pressing the flexible glue button, the control dabs the switch and switches the circuit to make miniature DC motor's frequency change.

Further setting the following steps: the base on be equipped with the recess, the recess on be equipped with first mounting and second mounting, first mounting and the cooperation of second mounting are spacing to be fixed the diode between first mounting and second mounting.

Through adopting above-mentioned technical scheme, the realization installation that the diode can be relaxed is dismantled to reach the change of different vibration frequency.

Further setting the following steps: the base is provided with a battery box.

Through adopting above-mentioned technical scheme, battery case an organic whole sets up on the base for electric toothbrush's an organic whole nature is stronger, and the volume is less relatively, portable.

To sum up, the utility model discloses following beneficial effect has: through pressing the flexible glue button, the control dabs the switch and switches the circuit to make miniature DC motor's frequency change, solved electric toothbrush only one vibration frequency, the problem that can't switch. Simultaneously, the realization installation that the diode can be relaxed and dismantlement to reach different vibration frequency's change, and battery case an organic whole sets up on the base, makes electric toothbrush's an organic whole nature stronger, and the volume is less relatively, portable.
