[0002] In daily life, traditional toothbrushing usually uses an ordinary toothbrush, but due to the influence of the brushing method and the traditional toothbrush structure, the traditional toothbrushing cleaning effect is not good. Electric toothbrushes can achieve better cleaning effects by changing the toothbrush structure and brushing method.

[0003] Existing electric toothbrushes generally use a sweeping vibration method to brush teeth, which can make the bristles clean the tooth surface and gaps more comprehensively. However, the functions of existing electric toothbrushes are relatively simple, and most of them are only set with a single gear in multiple modes, such as a cleaning mode, a whitening mode, etc. Each mode has only one intensity, which cannot be well suited to different users. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it includes a main control module 1, a motor control module 2, a lighting control module 3, and a sound control module 4. The main control module 1 is electrically connected to the motor control module 2, the lighting control module 3, and the sound control module 4. The motor control module 2 includes a sweeping vibration intensity module 21, a sweeping vibration angle module 22, and a sweeping vibration speed module 23.

DETAILED DESCRIPTION

[0028] See also Figure 1-11 As shown, the technical solution adopted in this specific implementation is: it includes a main control module 1, a motor control module 2, a light control module 3, and a sound control module 4. The main control module 1 is electrically connected to the motor control module 2, the light control module 3, and the sound control module 4. In this embodiment, the main control module performs global control through the MCU main control chip. All modes in the motor control module are selected by the main control module and then send control signals to the motor control module. The motor control module then controls the motor to operate. The light control module performs corresponding light indication according to the current working mode, and the sound control module performs sound prompts of the corresponding mode.

[0029] Specifically, the motor control module 2 includes a sweeping vibration intensity module 21, a sweeping vibration angle module 22, and a sweeping vibration speed module 23. The sweeping vibration intensity module 21, the sweeping vibration angle module 22, and the sweeping vibration speed module 23 are all provided with four gears. The different use modes of the traditional electric toothbrush are fixed effects, and the adaptability of different groups of people when using them is relatively weak. Therefore, in this embodiment, four gears are provided for different mode effects to be selected and used, so as to better meet the use needs of different groups of people and obtain the best cleaning effect;

[0030] The sweeping vibration intensity module 21 includes four intensity levels of 30%, 50%, 70% and 100%;

[0031] The sweeping angle module 22 includes four angle positions: 0-15°, 0-30°, 0-45° and 0-60°;

[0032] The sweeping speed module 23 includes four speed gears: 40%, 50%, 70% and 100%;

[0033] It can be understood that there are corresponding mode switches and gear switches on the toothbrush. Double-click the mode switch, and the indicator light will light up corresponding to different modes. At this time, single-click the mode switch to select the corresponding mode, and then single-click the gear switch to select different gears. After the selection is completed, double-click the mode switch to start using it;

[0034] The main control module 1 is provided with a vibration damping module 7, which is electrically connected to the motor control module 2. The startup time of the vibration damping module 7 is 5-6 seconds. A traditional electric toothbrush usually starts at normal intensity, and the teeth may feel uncomfortable at this time. Therefore, a vibration damping module is provided in the present embodiment. When the machine is turned on and used, the motor gradually speeds up within 5-6 seconds, giving the teeth a period of time to adapt, thereby providing better protection for the teeth.

[0035] More specifically, the motor control module 2 also includes a reminder module 24, which is activated every 30±1 seconds. In this embodiment, a humanized reminder module is also provided, which controls the motor to vibrate once every 30±1 seconds to remind the user to change direction.

[0036] More specifically, the light control module 3 controls the three-color lights of white, red and green. The light control module includes a constant light mode, a slow flashing mode, a fast flashing mode, and a breathing mode. In the present embodiment, a three-color light is provided. When charging, the red light is constant, and the green light flashes alternately in a breathing manner. When fully charged, the white light is constant, and the green light is constant. When the power is less than 30%, the green light flashes in a breathing manner to prompt charging, and the other lights are off. When the power is low, the red light flashes slowly, and the red light flashes quickly when the power is shut down due to low power. The white light remains constant during use.

[0037] More specifically, the main control module 1 is also provided with a memory module 5 and a charging module 6. The memory module 5 is electrically connected to the motor control module 2, the light control module 3, and the sound control module 4. After the mode is selected, double-clicking the mode switch will save the currently selected mode for memory. The next time the machine is turned on, the previous mode will be used by default. In the specific automatic timing mode, each mode is timed for 2 minutes of use. When it is close to 2 minutes, the motor will vibrate strongly once. You can click the mode switch to pause once and then restart. The memory length will be refreshed and the 2-minute use timing will be entered again.

[0038] In order to effectively protect the battery, a charging protection module 61 is provided on the charging module 6. The charging protection module 61 detects and controls the charging behavior through a sampling circuit, and stabilizes the power supply through a power supply circuit. When charging is detected, the control circuit stops supplying power to the motor, and resumes supplying power to the motor when there is no charging behavior. At the same time, it has an anti-overcharge function. When the battery charging voltage reaches 4.2V, charging is stopped. There is also a withstand voltage protection (direct charging) function. The charging protection module PCBA includes an OVP function. The hardware needs to add a TVS tube. The OVP sets the withstand voltage to 24V / 2A and shuts off the charging voltage at 6.5V. There is also an anti-reverse connection (direct charging) function. By adding an anti-reverse connection diode to the PCBA, damage caused by reverse connection of the charging line can be prevented. Multiple charging protections ensure the normal charging and use of the device.

[0039] The working principle of the utility model: when in use, the user first presses the mode switch on the toothbrush according to the use requirements to make corresponding selections for the sweeping vibration intensity, scanning angle, and sweeping vibration speed. The mode switch corresponds to the main control module 1 and the motor control module 2. When it is pressed for 2 seconds, it is turned on. The sound control module 4 controls the buzzer to emit two consecutive prompt sounds, and the motor control module 2 controls the motor to vibrate twice, and defaults to the use mode set when the machine was last shut down. At the same time, the motor rotation angle is controlled so that the toothbrush head returns to the center and aligns with the button after each startup. If you want to change the mode, double-click the mode switch, and the indicator light will light up corresponding to the different modes. Single-click the gear button to select the four gears. After the selection is completed, double-click the mode switch to exit the selection and memorize, and start using it. During use, the single mode switch can be suspended and used again.

[0040] The above description is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
