[0025] Example 1:

[0026] See also Figure 1 , Figure 1 The schematic diagram of the structure of the electric toothbrush control circuit of the present invention is shown, which includes: a control module 110, a drive module 120, a display module 130 and an input module 140, wherein the drive module 120, the display module 130 and the input module 140 are electrically connected to the control module 110 respectively.

[0027] The input module 140 is used to obtain the user's instructions for adjusting the working mode and working parameters of the electric toothbrush.

[0028] Among them, the control module 110 is used to determine the working mode of the electric toothbrush according to the working mode adjustment instruction, and determine the working parameters of the electric toothbrush according to the working parameter adjustment instruction; the working parameters include the vibration amplitude, sweeping angle and sweeping speed of the brush head.

[0029] The driving module 120 is used to drive the brush head according to the working mode and the working parameters.

[0030] The display module 130 is used to display the working mode and the working parameters.

[0031] The embodiment of the present utility model obtains the working mode adjustment instructions and working parameter adjustment instructions of the electric toothbrush based on the input module 140, so that the control module 110 can determine the target working mode and working parameters accordingly, and the driving module 120 drives the brush head to complete the corresponding action, thereby realizing the diversification and personalized setting of the electric toothbrush operation mode, and can meet the user's diverse cleaning needs in different scenarios.

[0032] In a specific implementation of an embodiment of the present invention, the working mode of the electric toothbrush includes a first working mode and a second working mode, and the working mode adjustment instruction includes a first mode adjustment instruction; the control module 110 is used to switch the working mode of the electric toothbrush between the first working mode and the second working mode according to the first mode adjustment instruction; the first working mode includes a plurality of simple gear modes with fixed working parameters, and the second working mode includes a plurality of complex gear modes with adjustable working parameters.

[0033] In one optional manner, the input module 140 includes multiple buttons, each button corresponding to an operation instruction; in another optional manner, the input module 140 includes a first button and a second button, and different operation instructions are implemented by combining the operations triggered by the first button and the second button. The embodiment of the present utility model takes the input module 140 including the first button and the second button as an example.

[0034] Among them, the first mode adjustment instruction is set to simultaneously press and hold the first button and the second button for more than a first preset time. For example, the first preset time can be set to 5 seconds. When the user simultaneously presses and holds the first button and the second button for more than 5 seconds, the control module 110 switches the working mode of the electric toothbrush from the first working mode to the second working mode, or from the second working mode to the first working mode.

[0035] In one optional embodiment, the display module 130 includes a display screen, which displays the working mode and working parameters of the electric toothbrush through text and / or patterns; in another optional embodiment, the display module 130 includes multiple indicator lights, and the multiple indicator lights display the working mode and working parameters of the electric toothbrush through their own lighting and extinguishing arrangements. In a specific implementation of the embodiment of the present utility model, the display module 130 includes 5 indicator lights, which are respectively arranged as the first indicator light, the second indicator light, the third indicator light, the fourth indicator light and the fifth indicator light. Preferably, the first indicator light and the second indicator light are arranged in a row, and the third indicator light, the fourth indicator light and the fifth indicator light are arranged together in another row.

[0036] Among them, the display module 130 is configured so that when the electric toothbrush switches from the first working mode to the second working mode, or from the second working mode to the first working mode, the five indicator lights light up simultaneously for a second preset time. Specifically, the second preset time can be set to 1 second, and the embodiment of the present utility model does not impose any specific restrictions on this.

[0037] The operating mode adjustment instruction includes a second mode adjustment instruction. When the control module determines that the current operating mode is the first operating mode, the operating mode of the electric toothbrush is switched between multiple simple gear modes according to the second mode adjustment instruction. Specifically, the multiple simple gear modes can be set to "daily mode", "gentle mode", "cleaning mode", "refreshing mode" and "sonic wave mode" respectively. Each simple gear mode has fixed operating parameters. Those skilled in the art can set the operating parameters of each simple gear mode according to the actual application scenario. The embodiment of the utility model does not impose specific restrictions on this.

[0038] In an optional manner, the input module 140 is also used to obtain a power on / off instruction, which is set to short press the first button. When the control module 110 determines that the current working mode is the first working mode, short press the first button to turn the electric toothbrush on or off.

[0039] In an optional manner, the second mode adjustment instruction is set to short press the second button. When the electric toothbrush is in working or standby state, the user short presses the second button to cycle through the working modes of the electric toothbrush between multiple simple gear modes, for example, switching the simple gear modes in the order of "daily mode" → "gentle mode" → "cleaning mode" → "refreshing mode" → "sonic wave mode" → "daily mode"...

[0040] Among them, each indicator light in the display module 130 corresponds to a simple gear mode. When the electric toothbrush is switched to any simple gear mode, the corresponding indicator light lights up and the other indicator lights go out.

[0041] In a specific implementation of an embodiment of the present invention, the first working mode also includes an ultra-cleaning mode, and the working mode adjustment instruction includes a third mode adjustment instruction; when the control module 110 determines that the current working mode is the first working mode, the working mode of the electric toothbrush is switched to the ultra-cleaning mode according to the third mode adjustment instruction; the working parameters corresponding to the ultra-cleaning mode are greater than the working parameters corresponding to any of the simple gear modes.

[0042] In an optional manner, the third mode adjustment instruction is set to long press the second button for more than a third preset time length. Specifically, the third preset time length can be set to 3 seconds. When the electric toothbrush is in working or standby state, and the control module 110 determines that the current working mode is the first working mode, the user long presses the second button for more than 3 seconds, and the control module 110 switches the working mode of the electric toothbrush to the ultra-clean mode according to the third mode adjustment instruction.

[0043] In an optional manner, the display module 130 is configured so that when the electric toothbrush enters the super cleaning mode, five indicator lights light up simultaneously.

[0044] In a specific implementation of an embodiment of the present invention, the working mode adjustment instruction includes a fourth mode adjustment instruction. When the control module determines that the current working mode is the second working mode, the working mode of the electric toothbrush is switched between multiple complex gear modes according to the fourth mode adjustment instruction.

[0045] Among them, the complex gear mode includes vibration amplitude mode, sweeping angle mode and sweeping speed mode. The electric toothbrush can adjust the vibration amplitude of the brush head in vibration amplitude mode, adjust the sweeping angle of the brush head in sweeping angle mode, and adjust the sweeping speed of the brush head in sweeping speed mode.

[0046] In an optional manner, the fourth mode adjustment instruction is set to short press the first button. When the control module 110 determines that the current working mode is the second working mode, the user short presses the first button, and the control module 110 switches the working mode of the electric toothbrush between multiple complex gear modes, for example, switching the complex gear modes in the order of "vibration amplitude mode" → "sweeping angle mode" → "sweeping speed mode" → power off → "vibration amplitude mode"...

[0047] In an optional method, if the first button is not triggered after the fourth preset time period, the first button is short pressed again, and the control module 110 memorizes the current complex gear mode and controls the electric toothbrush to shut down. When the electric toothbrush enters the second working mode next time, it automatically switches to the last memorized complex gear mode; the fourth preset time period can be set to 5 seconds.

[0048] In an optional manner, the display module 130 is configured so that when the electric toothbrush enters the vibration amplitude mode, the first indicator light turns on; when the electric toothbrush enters the sweeping angle mode, the second indicator light turns on; when the electric toothbrush enters the sweeping speed mode, the third indicator light turns on.

[0049] The complex gear mode includes multiple preset parameter gears corresponding to operating parameters, with the operating parameters corresponding to the parameter gears decreasing in order from top to bottom; when the control module determines that the current operating mode is the second operating mode, it adjusts one of the parameter gears upward or downward according to the operating parameter adjustment instruction. Optionally, the interval between adjacent vibration amplitudes is 1°, the interval between adjacent sweeping angle gears is 12°, and the interval between adjacent sweeping speed gears is 1 time / second. The specific number of parameter gears can be specifically set by those skilled in the art according to the actual application scenario. In a specific implementation of an embodiment of the present utility model, each complex gear mode includes 5 parameter gears with increasing working parameters: +1 gear, +2 gear, +3 gear, +4 gear and +5 gear. For example, the vibration amplitude gear includes 5 gears upward: 7°, 8°, 9°, 10° and 11°, the sweeping angle gear includes 6°, 18°, 30°, 42°, 54°, and the sweeping speed gear includes 1.5 times / second, 2.5 times / second, 3.5 times / second, 4.5 times / second, 5.5 times / second.

[0050] Among them, when the control module 110 determines that the current working mode is the vibration amplitude mode, it adjusts the vibration amplitude level up or down according to the working parameter adjustment instruction; when the control module 110 determines that the current working mode is the sweeping angle mode, it adjusts the sweeping angle level up or down according to the working parameter adjustment instruction; when the control module 110 determines that the current working mode is the sweeping speed mode, it adjusts the sweeping speed level up or down according to the working parameter adjustment instruction.

[0051] In one optional embodiment, the operating parameter adjustment instruction is configured to short-press a second button. When the control module 110 determines that the current operating mode is the vibration amplitude mode, the user short-presses the second button, causing the control module 110 to adjust the vibration amplitude level upward by one gear. When the control module 110 determines that the current operating mode is the sweeping angle mode, the user short-presses the second button, causing the control module 110 to adjust the sweeping angle mode upward by one gear. When the control module 110 determines that the current operating mode is the sweeping speed mode, the user short-presses the second button, causing the control module 110 to adjust the sweeping speed level upward by one gear. Specifically, when the control module 110 determines that the current operating mode is the second operating mode, the user short-presses the second button to cyclically switch the parameter levels in the order of "+1 gear" → "+2 gear" → "+3 gear" → "+4 gear" → "+5 gear" → "+1 gear" ...

[0052] The embodiment of the present invention can adjust the detailed working parameter levels of the electric toothbrush in the second working mode through the setting of multiple parameter levels to meet the needs of people who pursue deep cleaning, have sensitive teeth or have special oral care needs.

[0053] In an embodiment of the present invention, the electric toothbrush control circuit further includes a power module 150 electrically connected to the control module 110. The power module 150 is used to supply power to the control module 110, the drive module 120, the display module 130, and the input module 140. Specifically, the power module 150 can be configured as a 7.4V lithium battery.

It should be noted that the specific implementation of the control module 110 adjusting the working mode and working parameters of the electric toothbrush can be implemented by those skilled in the art based on the QFN40_5X5-LCP037BT32EU8 chip and according to the existing electric toothbrush control logic. However, the working modes and parameter levels of existing electric toothbrushes are relatively simple and limited. To meet the needs of people who pursue deep cleaning, tooth sensitivity, or have special oral care needs, the present embodiment provides more working modes, parameter levels, and a first button and a second button connected to the control module 110.

When the power module 150 is in a charging state, the power detection unit 111 detects the power level of the power module 150. If the power level of the power module 150 is less than 1 / 3, the third indicator light, the fourth indicator light and the fifth indicator light flash in sequence; if the power level of the power module 150 is between 1 / 3 and 2 / 3, the third indicator light is always on, and the fourth indicator light and the fifth indicator light flash in sequence; if the power level of the power module 150 is between 2 / 3 and 1, the third indicator light and the fourth indicator light are always on, and the fifth indicator light flashes; if the power module 150 is fully charged, the third indicator light, the fourth indicator light and the fifth indicator light are always on.
