In other embodiments, another solution for the program setting is to install a central processing unit in the electric toothbrush and load a main program for operating the operation mode, the central processing unit is connected with a short-range communication module, for example, through Zigbee, bluetooth, Wifi, NFC, infrared transmission, RF wireless transmission module, etc., short-range communication is the prior art, and the present invention does not describe this part in detail, so that another storage module can be installed on the external device, the other storage module can store parameters for setting and/or modifying the self-cleaning operation mode, the set and/or modified parameters are transmitted to the electric toothbrush through a short-range communication protocol, and the central processing unit loads these parameters into the main program, so that the operation mode is set or modified. Of course, the main program should have a modifiable range, or the user has limited rights to prevent the parameter setting from being invalid. For this solution, the manufacturing cost is increased relative to the solution using a microprocessor, but this does not represent that the solution using a central processing unit is not preferable.
In a preferred embodiment, the invention further provides a pressure detection module (not shown), the pressure detection module is arranged on the brush head and can sense the stressed part of the brush bristles, and the pressure detection module is connected with the self-cleaning processing module and is used for acquiring the current pressure value P0 of the brush head and transmitting the current pressure value P0 to the self-cleaning processing module; the storage module stores a preset pressure value P1; when P0 < P1 and the self-cleaning mode is selected, the self-cleaning processing module instructs the self-cleaning driving member to perform the self-cleaning mode.
In another preferred embodiment, the present invention further provides a memory module for recording the selected mode each time, after the self-cleaning mode is finished, the self-cleaning processing module starts to stand by or shut down according to the previous self-cleaning operation mode of the current self-cleaning mode, for example, the user self-cleans the toothbrush after brushing teeth, at this time, the processing module determines that the previous operation mode is the tooth brushing mode, and therefore, after the self-cleaning mode is finished, the self-cleaning processing module executes shutdown; for another example, before the user brushes the teeth, the processing module determines that the previous operation mode is the self-cleaning mode, or the processing module determines that the previous operation mode is the tooth brushing mode but the time from the current operation exceeds a preset time (for example, the preset time is 4 hours), after the self-cleaning mode is finished, the processing module executes a standby operation to wait for the user to input a relevant selection, and if the preset operation interval time is exceeded, the processing module executes a shutdown. As a beneficial effect, the self-cleaning mode is well embodied, if the user starts the self-cleaning mode after the tooth brushing mode, the electric toothbrush enters the shutdown state after the self-cleaning mode is finished, manual operation of the user is not needed, the phenomenon that the shutdown is missed due to forgetting of the user is avoided, or the user does not need to pay attention to the self-cleaning mode after tooth brushing.
The circuit part of the invention is briefly explained below.

In still another embodiment, the invention further provides an LED lamp arranged on the brush head, wherein the LED lamp can be an ultraviolet LED lamp, a blue LED lamp or a red LED lamp, and the disinfection, whitening and health-care functions are added to the toothbrush. The self-cleaning ultraviolet lamp is used for sterilizing and disinfecting the self-cleaning brush head. The arrangement has good sterilization effect, particularly, when the self-cleaning brush runs in a self-cleaning mode, through experiments, the cleaning liquid prepared in the above way is filled in the accommodating cup 30, when the line time of the motor 50 is 20 seconds, the duty ratio is 40% -80%, the self-cleaning brush head has two vibration frequencies, the two vibration frequencies run alternately, wherein the higher frequency is 350Hz, the lower frequency is 250Hz, the ultraviolet lamp is turned on, and at the moment, the bacteria removal rate in the brush bristles is as high as 99%.
