[0002] Electric toothbrushes are increasingly becoming common washing and protecting appliances in families. At present, most of the electric toothbrushes on the market use a single button to provide a mode of all control functions, which is currently a mainstream control mode. A pure mechanical key switch control method judges whether to prevent false touch by the length of time triggered by the key. The accuracy of this processing method is not high, and there are certain loopholes in the judgment of the triggering time. False touch within a reasonable range cannot be avoided. False triggering often occurs during transportation and handling, which reduces the experience of customers.

[0038] Figure 2 is a structural block diagram of an electric toothbrush provided according to embodiments of the present application, as Figure 2 shown, the electric toothbrush includes: a handle shell 21, a motor 22, an ultrasonic pressure sensor 23, a master control processor 24, a motor drive 27, a battery 25 and a tail cover 26, which are described below.

[0039] The handle shell 21, a recess is provided on the outer surface of the handle shell.

[0040] The motor 22 is arranged inside the handle shell.

[0041] The ultrasonic pressure sensor 23 is connected with the master control processor and arranged on the inner surface of the handle shell at a position corresponding to the recess, for generating and outputting first and second signals to the master control processor, wherein the first signal is a signal generated by the ultrasonic pressure sensor detecting the pressure change at the recess position, and the second signal is a signal generated by the ultrasonic pressure sensor detecting the ultrasonic wave echo at the recess position.

[0042] The master processor 24 is connected with the ultrasonic pressure sensor, and is configured to generate a control instruction for controlling the electric toothbrush according to the received first signal and second signal.

[0043] The motor drive 27 is connected with the master processor at one end and connected with the motor at the other end, and is configured to drive the motor.

[0044] The battery 25 is arranged inside the handle shell, and is configured to supply power to the motor, the master processor, the motor drive and the ultrasonic pressure sensor.

[0045] The tail cover 26 is connected with the bottom of the handle shell.

[0046] In the embodiment, the recess is arranged on the outer surface of the handle shell, and the ultrasonic pressure sensor is arranged at the inner surface of the handle shell corresponding to the recess, and the recess and the ultrasonic pressure sensor corresponding thereto constitute the key of the electric toothbrush. Since the mechanical key has poor waterproofness in structure, and the electric toothbrush is in contact with water in most use cases, the mechanical key is not suitable for the use environment of the electric toothbrush, therefore, the electric toothbrush in the present application does not use a clear mechanical key to indicate the position of the key to the user, but a recess is arranged at the key of the outer surface of the handle shell, and a pattern can be marked at the position of the recess to indicate the position of the key to the user, so that the electric toothbrush provided in the present application is integrated and seamless, and the waterproof effect of the key is achieved. At the same time, when the user presses the key with the skin, the structure of the recess is beneficial to concentrate the pressure applied on the whole recess at the geometric center of the recess, which is beneficial to the ultrasonic pressure sensor to collect pressure data. When the user presses the key with the skin, the ultrasonic pressure sensor detects the pressure change amount at the recess, and transmits the generated first signal representing the pressure change amount to the master processor; the ultrasonic pressure sensor is also configured to emit an ultrasonic signal, when a target object contacts the recess, the emitted ultrasonic signal is reflected to the ultrasonic pressure sensor by the surface of the target object, at this time, the ultrasonic pressure sensor receives and analyzes the ultrasonic echo reflected at the recess, detects whether the target object is human skin, and sends the generated second signal representing whether the target object is human skin to the master processor. The master processor receives the first signal and the second signal transmitted by the ultrasonic pressure sensor, applies the toothbrush starting method written in the present application to judge whether the touch of the target object on the recess is a false touch, and executes the corresponding starting method. The tail cover of the electric toothbrush is connected with the bottom of the handle shell, and is configured to protect the internal components of the electric toothbrush from water.

[0047] As an optional embodiment, the handle shell comprises: a rectangular recess, the recess is arranged on the inner surface of the handle shell at a position corresponding to the recess, and the depth of the recess is not greater than 0.4mm; the ultrasonic pressure sensor is arranged at the geometric center of the recess, and the distance between the ultrasonic pressure sensor and any frame of the recess is not less than 0.3mm.

[0048] Optionally, the handle shell is provided with a recess at a position corresponding to the recess on the inner surface and the outer surface, which is used to place the ultrasonic pressure sensor. The recess can effectively place other components inside the electric toothbrush to affect the ultrasonic pressure sensor, and can prevent the detection of the ultrasonic pressure sensor from failing. The ultrasonic pressure sensor can be arranged at the geometric center of the recess, and the recess can be rectangular. The depth of the recess is not greater than the thickness of the ultrasonic pressure sensor, that is, 0.4mm, so as to avoid contact with the circuit board included in the ultrasonic pressure sensor and affect the detection effect. At the same time, the distance between any frame of the recess and the ultrasonic pressure sensor is not less than 0.3mm, so as to avoid affecting the detection effect of the ultrasonic pressure sensor.

[0049] As an optional embodiment, the material of the handle shell and the thickness between the recess and the recess of the handle shell are any one of the following combinations: the material of the handle shell is polycarbonate, and the thickness between the recess and the recess is not greater than 2mm; the material of the handle shell is glass, and the thickness between the recess and the recess is not greater than 5mm; the material of the handle shell is stainless steel, and the thickness between the recess and the recess is not greater than 1mm; the material of the handle shell is aluminum, and the thickness between the recess and the recess is not greater than 5mm; the material of the handle shell is acrylonitrile-butadiene-styrene plastic, and the thickness between the recess and the recess is not greater than 5mm.

[0050] Optionally, the thickness of the handle shell between the recess and the recess will affect the accuracy of the detection of the ultrasonic pressure sensor, because the ultrasonic pressure sensor needs to receive and analyze the ultrasonic echo reflected by the surface of the target object contacting the recess. The thicker the thickness of the handle shell between the recess and the recess, the weaker the ultrasonic echo received by the ultrasonic pressure sensor. When the material of the handle shell is different, the thickness of the handle shell between the recess and the recess should also be different. The present application gives five corresponding relationships between the material and the thickness. The material and the thickness of the handle shell can be any one of the five combinations.

[0051] As an optional embodiment, the electric toothbrush comprises: a plurality of ultrasonic pressure sensors, a plurality of recesses and a plurality of recesses, wherein the plurality of recesses correspond to the plurality of recesses one by one, the plurality of ultrasonic pressure sensors are arranged in the plurality of recesses, and the distance between two adjacent recesses in the plurality of recesses is not less than 5mm.

[0052] Optionally, the electric toothbrush can comprise a plurality of ultrasonic pressure sensors, a plurality of grooves and a plurality of recesses, wherein one ultrasonic pressure sensor and one groove and one recess can constitute a key of the electric toothbrush, and the plurality of ultrasonic pressure sensors, the plurality of grooves and the plurality of recesses one-to-one correspond to constitute keys equal in number to the three. When the electric toothbrush comprises a plurality of keys, the distance between the grooves of each key is not less than 5 mm, so as to prevent the ultrasonic pressure sensors corresponding to any two adjacent keys from affecting each other.

[0053] As an optional embodiment, the ultrasonic pressure sensor comprises a flexible printed circuit board and a sensor chip located on the surface of the flexible printed circuit board, wherein the sensor chip is arranged between the inner surface of the handle shell and the flexible printed circuit board.

[0054] Optionally, the ultrasonic pressure sensor can comprise a flexible circuit board and a sensor chip, the flexible printed circuit board is a carrier of the integrated sensor and the resistance-capacitance component, and the sensor chip is used to detect the pressure change amount of the recess and emit and receive ultrasonic signals. Figure 3 is a structural schematic diagram of the key of the electric toothbrush according to an optional embodiment of the present application, as shown in Figure 3 When the ultrasonic pressure sensor is connected with the handle shell, the surface of the sensor chip 31 is first connected with the surface of the flexible printed circuit board 32, and then the surface of the sensor chip not connected with the flexible printed circuit board is connected with the handle shell. Because the surface of the sensor chip not connected with the flexible printed circuit board in the ultrasonic pressure sensor is more sensitive, it is beneficial to detect the pressure change of the recess and the ultrasonic signal.

[0055] As an optional embodiment, the electric toothbrush comprises a flexible circuit board wire and a flexible circuit board socket arranged in the interior of the handle shell and connected with the ultrasonic pressure sensor and the main control processor respectively, and used for transmitting detection signals.

[0056] Optionally, the internal circuit of the electric toothbrush is connected through the flexible circuit board wire and the flexible circuit board socket for signal transmission.

[0057] As a specific embodiment, Figure 4 is a front view of the electric toothbrush according to an optional embodiment of the present application, as shown in Figure 4 is a cross-sectional view and an external surface schematic diagram of the electric toothbrush respectively. Figure 5 is an exploded view of the electric toothbrush according to an optional embodiment of the present application, as shown in Figure 5As shown, the electric toothbrush comprises a handle shell 21, a motor 22, a battery 25, a tail cover 26, a sensing chip 31, a flexible printed circuit board 32, a waterproof rubber plug 51, a waterproof support frame 52, a motor rotating shaft 53, a groove 54 of the motor rotating shaft, a rotating shaft pressure sensor 55, a main control connector 56, a flexible circuit board wire 57 and a flexible circuit board socket 58. When the electric toothbrush handle shell 21 outer surface recess senses the slight pressure of the finger, the electric toothbrush handle shell 21 outer surface transmits the deformation information to the electric toothbrush handle shell 21 inner surface through the slight deformation variable, the glue fixing medium sticks the flexible printed circuit board 32 to the electric toothbrush handle shell 21 inner surface, the micro variable transmitted by the electric toothbrush handle shell 21 inner surface is first transmitted to the flexible printed circuit board 32 and then to the sensing chip 31 on the flexible printed circuit board 32, so as to convert the deformation variable into the pressure value change variable, and the sensing chip 31 simultaneously detects through ultrasonic waves to realize the detection of the pressing action of the finger. The data collected by the sensing chip 31 is connected to the main board of the electric toothbrush through the flexible circuit board wire 57, and the data collection and the main board are connected through the flexible circuit board socket 58 and the main control connector 56 on the main board, so that the sensing chip 31 transmits the collected data to the main control unit of the main board, thereby realizing the conversion of the analog signal into the data signal, the signal processing into useful information, the different trigger button signal function realized by the main control processor, and the functions of long pressing, short pressing and false touch judgment of the button.

[0058] According to the embodiment of the present application, a toothbrush starting method for implementing the above electric toothbrush is also provided, Figure 6 The flowchart of the toothbrush starting method is shown in FIG. 2. Figure 6 The method comprises the following steps:

[0059] In step S602, a first signal and a second signal are received, wherein the first signal and the second signal are signals generated by an ultrasonic pressure sensor in response to the touching action of an object on the recess, the first signal is used to describe the pressure value of the recess, and the second signal is used to represent the material of the object.

[0060] In this step, the first signal is the signal of the pressure change variable generated by the ultrasonic pressure sensor in response to the touching action of the corresponding target object on the recess of the outer surface of the electric toothbrush, and the second signal is the signal generated by the ultrasonic pressure sensor for representing the material of the target object in response to the ultrasonic echo reflected by the surface of the target object. The first signal and the second signal are both signals generated by the ultrasonic pressure sensor in response to the touching action of the target object on the recess, and are transmitted to the main control processor, and the main control processor receives the first signal and the second signal.

[0061] In step S604, a starting instruction is generated according to the first signal and the second signal.

[0062] In this step, the main control processor determines whether the touch action of the target object touching the recess is a false touch action according to the first signal and the second signal, and generates a corresponding start instruction.

[0063] In step S606, the electric toothbrush is started according to the start instruction.

[0064] In this step, the main control processor transmits the start instruction to each component of the electric toothbrush according to the start instruction, and controls the electric toothbrush to start.

[0065] Through the above steps, the electric toothbrush achieves the purpose of detecting whether it is a human hand touching the key, thereby realizing the technical effect of preventing false touch of the electric toothbrush key, and further solving the technical problem of false touch of the key of the electric toothbrush in the related art.

[0066] As an optional embodiment, the start instruction can be generated according to the first signal and the second signal by the following steps: determining whether the touch action is an action that the electric toothbrush needs to respond to according to the first signal and the second signal; and generating the start instruction in the case that the touch action is the action that the electric toothbrush needs to respond to.

[0067] Alternatively, the main control processor determines whether the touch action of the target object touching the recess is a false touch action according to the first signal and the second signal, and generates a corresponding start instruction. When the touch action is a false touch, for example, the target object is not human skin, but metal or plastic, which may be a false touch action when carrying the electric toothbrush. At this time, the main control processor does not generate the start instruction. Or the human skin is in the recess of the handle shell, but according to the pressure signal, it is determined that the person does not press the key. In this case, it is also a false touch action, and the main control processor does not generate the start instruction. Only in the case that the first signal and the second signal both meet certain conditions, the start instruction is generated and the electric toothbrush is started, thereby realizing the technical effect of reducing false touch.

[0068] As an optional embodiment, whether the touch action is an action that the electric toothbrush needs to respond to can be determined according to the first signal and the second signal by the following steps: generating a first determination result according to whether the first signal is greater than a pressure threshold; generating a second determination result according to whether the second signal represents that the material of the object is skin; and determining whether the touch action is the action that the electric toothbrush needs to respond to according to the first determination result and the second determination result.

[0069] Optionally, it can be judged whether the pressure signal represented by the first signal is greater than a pressure threshold value, whether the target object is pressing the button, and a first judgment result is generated; then when the first judgment result is yes, it is further judged whether the target object is human skin according to the second signal, and a second judgment result is generated; when the second judgment result is yes, it is determined that the touch action needs the electric toothbrush to respond, and it is not a false touch. It should be noted that there is no time sequence requirement for generating the first judgment result and the second judgment result. The first judgment result and the second judgment result can also be generated at the same time, and whether the touch action needs the electric toothbrush to respond is determined according to the two results. Only the calculation amount of generating the first judgment result according to whether the first signal is greater than the pressure threshold value is smaller, and when the first judgment result is no, it is not necessary to perform redundant calculation to determine that the touch action does not need the electric toothbrush to respond.

[0070] As an optional embodiment, according to the first judgment result and the second judgment result, whether the touch action is an action that needs the electric toothbrush to respond can be determined by the following steps: when the first judgment result determines that the first signal is greater than the pressure threshold value and the second judgment result determines that the second signal represents the material of the object as skin, it is determined that the touch action is an action that needs the electric toothbrush to respond.

[0071] Optionally, when the first judgment result determines that the first signal is greater than the pressure threshold value and the second judgment result determines that the second signal represents the material of the object as skin, it is determined that the touch action is an action that needs the electric toothbrush to respond.

[0072] As an optional embodiment, according to the first signal and the second signal, whether the touch action is an action that needs the electric toothbrush to respond can be determined by the following steps: according to the first signal and / or the second signal, the touch duration of the touch action is determined; when the touch duration is less than a duration threshold value, it is determined that the touch action is not an action that needs the electric toothbrush to respond, and when the touch duration is greater than the duration threshold value, it is determined that the touch action is an action that needs the electric toothbrush to respond.

[0073] Optionally, the touch duration of the touch action can be determined according to the first signal and / or the second signal. The first signal represents the pressure value applied to the groove area by the touch action, and the touch duration can be determined by detecting the duration of the pressure value meeting a certain threshold. The second signal represents the material of the contact groove area, and the touch duration can be determined by detecting the duration of the skin contacting the groove area. The first signal and the second signal can also be considered comprehensively to determine the duration of the skin contacting the groove area and meeting a certain threshold pressure value as the touch duration. Subsequently, the touch duration can be used to determine whether the touch action is an action that the electric toothbrush needs to respond to. When the touch duration is less than the duration threshold, it is determined that the touch action is not an action that the electric toothbrush needs to respond to. Preferably, the duration threshold can be selected as 40 ms. When the touch duration is in different time ranges, the corresponding start instruction can be generated according to the touch duration. For example, when the touch duration is greater than 40 ms and less than 1 s, it is determined that the touch is a short press, and the start instruction corresponding to the short press key is generated. When the touch duration is greater than 1 s, it is determined that the touch is a long press, and the start instruction corresponding to the long press key is generated.

[0074] As an optional embodiment, in the case where the touch action is an action that the electric toothbrush needs to respond to, the generation of the control instruction can be achieved by the following steps: determining the pressure peak value in the first signal; selecting a target working mode from a plurality of working modes of the motor according to the pressure peak value and the touch duration, wherein the plurality of working modes correspond to different combinations of motor working frequency and motor amplitude; and generating the control instruction according to the target working mode.

[0075] Optionally, the motor of the electric toothbrush provided by the application includes a plurality of working modes, and the frequencies and amplitudes of the motor in the plurality of working modes are different. When it is determined that the touch action is an action that the electric toothbrush needs to respond to, the intention of the user can be judged according to the touch duration and the pressure of the touch action, and a target working mode can be selected from the plurality of working modes of the motor. The control instruction is to adjust the frequency and amplitude of the motor to the frequency and amplitude in the target working mode. Specifically, when the user presses the key to use the electric toothbrush, the master control processor can determine whether the user is long pressing or short pressing according to the duration of the user's touch action, and can also determine whether the user is light pressing or heavy pressing according to the pressure peak value generated by the user's touch action. Then, the working frequency and amplitude of the motor can be determined according to the specific action of the user.

[0076] As a specific embodiment, when the electric toothbrush is installed with the ultrasonic pressure sensor to prevent false touch, the specific working process is as follows: when the whole system is powered on, the false touch button system is started, when the recess of the electric toothbrush handle shell senses pressure and generates corresponding deformation, the deformation is transmitted to the ultrasonic pressure sensor through the handle shell, the ultrasonic pressure sensor converts the deformation into a quantifiable pressure value, and transmits the detected pressure signal and ultrasonic echo to the main control processor, the main control processor makes two levels of judgments, first judges whether the measured pressure value reaches the pressure trigger threshold, and then judges whether there is a finger contacting the button according to the ultrasonic detection, when the two judgments are both yes, it is judged that this touch is a trigger signal. If it is judged as a trigger signal, the trigger signal is analyzed, whether it is long press, short press or false touch is judged by the trigger time, and the corresponding button operation of long press, short press, false touch not executed and the like is executed.

The size of the pressure sensing area can be determined according to the size and effective area of the ultrasonic pressure sensor. The depth and curvature of the groove of the pressure sensing area can be determined according to the material medium of the pressure sensing area and the transmission effect.

[0079] S703 is a glue fixing medium, which can ensure that the ultrasonic pressure sensor can be fixed flat on the inner wall of the pressure area and will not be loose due to vibration. When using glue to fix the ultrasonic pressure sensor on the inner wall of the pressure area, a certain amount of glue is taken, the glue is first ensured to be applied to the inner wall of the pressure area, and then the ultrasonic pressure sensor is firmly and flatly attached to the inner wall of the pressure area without air bubbles through a jig.

[0080] S704 is an ultrasonic pressure sensor, which integrates a pressure sensor unit and a capacitive sensor unit, the pressure sensor unit is responsible for sensing the change of the pressure in the pressure area, and the ultrasonic sensor unit is responsible for detecting ultrasonic echo, also known as skin sensing detection. When the detection results of the two units meet the predetermined conditions at the same time, the key sensing function is triggered, thereby realizing the technical effect of avoiding false triggering.

[0081] S705 is a circuit board, which is a carrier of integrated sensors and capacitive components, and different circuit board types can be selected according to different carrier sensors. The ultrasonic pressure sensor provided by the application selects a flexible PCB board of FPC, the back of the sensor is reinforced by PI material, and the entire PCB board is not more than 0.3 mm; the flexible PCB board of FPC is pasted to the back of the ultrasonic pressure sensor, and then the front of the ultrasonic pressure sensor is pasted to the inner wall of the pressure area.

[0082] S706 is a FPC flat cable, which mainly connects the circuit board attached to the ultrasonic pressure sensor to the main control circuit board and transmits data to the judgment circuit and the main control processor.

[0083] S707 is a main control processor, which mainly processes the data collected by the ultrasonic pressure sensor and takes certain judgment and operation key functions.

[0084] S711 is a key function: when the key trigger condition is met, the key function operation is performed. Basic key function operations include: long press, short press, and false touch press, wherein the false touch press does not perform any operation, the long press turns on and off the switch, and the short press switches the mode or gear.

Pins 5, 6, 9, and 10 can all be connected to a high-resistance resistor and then to a 3.3V voltage. It's important to note that pins 7 and 8 can accept a fixed voltage signal. This voltage value can be pre-determined based on the material and thickness of the circuit board connected to the ultrasonic pressure sensor. When the voltage values ​​connected to pins 7 and 8 are adjusted to match the material and thickness of the circuit board, the ultrasonic pressure sensor can simultaneously perform pressure and ultrasonic detection.
