[0036] Embodiment 1

[0037] Figure 1 This is a flow chart of a control method for a personal cleaning and care device provided in Example 1 of the present invention. This embodiment is applicable to the case where a single button is used to achieve a multi-function control effect on a personal cleaning and care device (such as an electric toothbrush, an oral irrigator, etc.) with high waterproof requirements. The personal cleaning and care device includes a multi-function button; the multi-function button includes an elastic protrusion, and a force vector sensor disposed at the bottom of the elastic protrusion. Accordingly, Figure 1 As shown, the control method specifically includes the following steps:

[0038] S11. Obtaining a vector pressure signal of the force projection of the elastic protrusion on a preset reference plane based on the force vector sensor measurement.

[0039] S12. Generate a first control instruction with a directional characteristic according to the vector pressure signal, so as to control the operation of the personal cleaning and care device according to the first control instruction.

[0040] Specifically, the elastic protrusion can be fitted and fixed on the shell of the personal cleaning and care device to achieve a waterproof effect. The top of the elastic protrusion, that is, the part on the outside of the shell, can be squeezed by the user. Based on different force directions, the corresponding vector force distribution can be generated at the bottom of the elastic protrusion, that is, the part on the inside of the shell, and the user can also be provided with a sense of squeezing feedback in the corresponding direction. Among them, the elastic protrusion can be made of soft glue material, or a combination of soft glue and hard glue, with elastic characteristics. Further, a hard object can be fixed on the top of the elastic protrusion to meet the user's hard feel requirements, and the user can squeeze the elastic protrusion by pressing the hard object. The force vector sensor is arranged at the bottom of the elastic protrusion and can be fixedly connected to the elastic protrusion, which can be used to measure the force vector, that is, the magnitude of the force and the direction of the force, received by the elastic protrusion. Further, the force vector sensor can be connected to the circuit board inside the personal cleaning and care device, and the control method can be implemented by the circuit board.

[0041] The user can squeeze the elastic protrusion in any direction, such as horizontal vector friction on the top and pressing downward or diagonally downward, etc., to form a force on the elastic protrusion, so that the force vector of the force can be measured by the force vector sensor. The force vector can be further projected onto a preset reference plane to obtain a vector pressure signal, wherein the preset reference plane can be a plane perpendicular to the positive pressing direction of the multi-function button, specifically, it can be the bottom surface of the elastic protrusion. The vector pressure signal can present any direction on the preset reference plane. Taking an electric toothbrush as an example, when the multi-function button is facing the user and the toothbrush head is placed upward, the direction of the vector pressure signal can be upward, downward, left, right, and various diagonal directions, etc.

[0042] After obtaining the vector pressure signal, a first control instruction with a directional feature can be generated according to the vector pressure signal. Different first control instructions can be generated based on different directions to correspond to the user's squeezing operations in different directions, so as to realize multiple functions of a single button. Exemplarily, the personal cleaning and care device has a screen, and the upward vector pressure signal can generate a first control instruction for sliding the screen content upward, the downward vector pressure signal can generate a first control instruction for sliding the screen content downward, the leftward vector pressure signal can generate a first control instruction for sliding the screen content leftward, the rightward vector pressure signal can generate a first control instruction for sliding the screen content rightward, and the oblique vector pressure signal can generate a first control instruction for sliding the screen content obliquely, etc. Another exemplary example is that the upward or downward vector pressure signal can generate a first control instruction for adjusting the working gear, and the left or right vector pressure signal can generate a first control instruction for adjusting the working mode in a specified order, etc. At the same time, the vector pressure signal has a size, and when generating the first control instruction, the size information of the corresponding vector pressure signal can also be combined. For example, the corresponding first control instruction is generated only when the size of the vector pressure signal exceeds the preset size threshold to avoid accidental touch. For example, the adjustment range of the working parameter or the screen sliding length can be determined according to the magnitude of the vector pressure signal. After the first control instruction is generated, the personal cleaning and care device can be controlled to perform corresponding actions according to the instruction.

[0043] On the basis of the above technical solution, optionally, the force vector sensor includes a plurality of pressure sensors dispersedly arranged at the bottom of the elastic protrusion; the vector pressure signal of the force projection of the elastic protrusion on a preset reference plane measured based on the force vector sensor includes: acquiring the pressure signals collected by each of the pressure sensors; according to the pressure signals, determining two by two to obtain a corresponding force vector signal on the preset reference plane; if one force vector signal is obtained, the force vector signal is used as the vector pressure signal; if multiple force vector signals are obtained, the multiple force vector signals are vector synthesized to obtain the vector pressure signal.

[0044] Specifically, the force vector sensor can be a combination of multiple pressure sensors in specific directions designed using MEMS technology. Preferably, the directions of the multiple pressure sensors are arranged along the normal direction of the preset reference plane. Multiple pressure sensors can be dispersedly arranged at the bottom of the elastic protrusion, so that pressure signals at multiple positions on the bottom can be collected. The collected pressure signals can be corrected in advance according to the calibration values ​​of the corresponding pressure sensors, and the corrected pressure signals can be used for subsequent calculations to eliminate the reading deviation caused by the inherent prestress of each pressure sensor after installation, wherein the inherent prestress to which each pressure sensor is subjected may be different, that is, the calibration values ​​of each pressure sensor may be different.

[0045] For every two pressure signals, a two-dimensional force vector calculation can be performed on the normal plane of the preset reference plane of the corresponding two pressure sensors to obtain a one-dimensional force vector signal projected onto the preset reference plane. When there are only two pressure sensors, a force vector signal can be calculated, and the force vector signal can be directly used as the required vector pressure signal. At this time, the vector pressure signal has only two directions, such as up and down, and the corresponding multi-function button can realize an axial slider-type control. When more than three pressure sensors are distributed, more than two force vector signals can be calculated, and then all force vector signals can be vector synthesized to obtain the required vector pressure signal. The exemplary vector pressure signal calculation process is as follows: Figure 2 As shown, Figure 2 The example of using three pressure sensors is shown in FIG. Thus, three-dimensional force vector calculation can be realized, and a two-dimensional vector pressure signal projected onto a preset reference plane can be obtained, that is, a vector pressure signal in any direction on the preset reference plane, and the corresponding multi-function button can realize plane control.

[0046] Further optionally, multiple pressure sensors are arranged in the same direction; and based on the pressure signals, a corresponding force vector signal on the preset reference plane is determined two by two, including: determining the size information and direction information of the corresponding force vector signal based on the difference between each two pressure signals.

[0047] Specifically, for each two pressure signals obtained, the absolute value of the difference between the two pressure signals can be used as the magnitude of the corresponding force vector signal, and the direction of the corresponding force vector signal can be determined according to the positive or negative sign of the difference, specifically, the direction from one pressure sensor to another pressure sensor. For example, Figure 3 As shown, taking two pressure sensors as an example, based on the force F of the elastic protrusion, pressure sensor 1 collects the pressure signal of the force component F1 at the corresponding position, and pressure sensor 2 collects the pressure signal of the force component F2 at the corresponding position. The magnitude and direction of the force vector signal (also the vector pressure signal at this time) can be expressed according to the magnitude difference between F1 and F2. If F1>F2, it means Figure 3 In the middle left direction, if F1<F2, it means Figure 3 When multiple pressure sensors are set in different directions, the collected pressure signals can be converted to the same direction before calculation.

[0048] On the basis of the above technical solution, optionally, after obtaining the vector pressure signal of the force projection of the elastic protrusion on a preset reference plane based on the force vector sensor, the method further includes: if the magnitude of the vector pressure signal is less than a preset vector threshold, determining a press signal in the normal direction of the preset reference plane according to the pressure signal; generating a second control instruction corresponding to a button press or a button lift according to the press signal, so as to control the operation of the personal cleaning and care device according to the second control instruction.

[0049] Specifically, if the magnitude of the obtained vector pressure signal is less than the preset vector threshold, it means that the vector feature is not obvious, and it can be considered that the user does not want to perform a vector operation on the preset reference plane, but rather performs a pressing operation in the normal direction of the preset reference plane. At this time, the pressing signal in the normal direction of the preset reference plane can be calculated based on the pressure signals collected by each pressure sensor, so as to identify the user's pressing action or lifting action based on the magnitude of the pressing signal, so as to generate a corresponding second control instruction, and the personal cleaning and care device can be controlled to perform a corresponding action according to the instruction.

[0050] Further optionally, the directions of the plurality of pressure sensors are arranged along the normal direction of the preset reference plane; and the step of determining the pressure signal in the normal direction of the preset reference plane according to the pressure signal comprises: determining the magnitude information of the pressure signal according to the average value of each of the pressure signals. Figure 3 As shown, when the absolute value abs(F1-F2) of the difference between the magnitudes of F1 and F2 is less than the preset vector threshold, it indicates that the vector feature is not obvious, and the average value of F1 and F2 can be used as the magnitude of the pressing signal.

[0051] On the basis of the above technical solution, optionally, the multi-function button also includes a feedback module; after generating a first control instruction with a directional characteristic according to the vector pressure signal, the method also includes: controlling the feedback module to generate a physical feedback signal according to the first control instruction.

[0052] Specifically, a feedback pole may be provided below the multi-function button for connecting a feedback module for control. The feedback module may include a vibration motor, an ultrasonic generator, a transient discharge electrode or a temperature variable element, etc. After generating the first control instruction, a corresponding feedback module control signal may be generated according to the first control instruction, so as to control the feedback module to generate a corresponding physical feedback signal through the control signal, thereby facilitating providing the user with a corresponding tactile feedback sense. Based on the feedback module used, the corresponding physical feedback signal may be mechanical vibration, ultrasonic vibration, electric pulse, temperature change, etc. When there is only one feedback pole, a simple feedback sense without directional characteristics may be provided, such as realizing feedback expression for triggering the first control instruction.

[0053] Similarly, after generating the second control instruction corresponding to the key pressing or key lifting according to the pressing signal, the feedback module may be controlled to generate a corresponding physical feedback signal according to the second control instruction.

[0054] Further optionally, the feedback module includes a plurality of feedback units arranged in an array; and controlling the feedback module to generate a physical feedback signal according to the first control instruction includes: forming the physical feedback signal with a direction change characteristic based on the time difference between the feedback signals generated by each of the feedback units, and the direction change characteristic corresponds to the direction characteristic.

[0055] Specifically, an array of feedback poles may be provided below the multi-function button, such as a 2×2 array or a 3×3 array, etc. The exemplary feedback pole arrangement is as follows: Figure 4 As shown, a large circle on the outside represents the projection of the outline of the elastic protrusion on the preset reference plane, and multiple small circles on the inside represent the projection of the positions of each feedback pole on the preset reference plane. Each feedback pole can be connected to a feedback unit to control each feedback unit to independently generate physical feedback. Then, by controlling each feedback unit to generate its own feedback signal at different times, a physical feedback signal with a direction change characteristic can be formed as a whole, and at the same time, the direction change characteristic of the physical feedback signal can be made to correspond to the direction characteristic of the first control instruction, thereby providing the user with a directional feedback sense corresponding to the vector operation he or she wishes to perform. For example, when the feedback signals of each feedback unit are controlled to occur in a certain direction in sequence, even if the finger contact does not displace, it will give the skin nerve an illusion of displacement, thereby generating a tactile feedback with a direction change characteristic on the skin of the contacted finger.

[0056] Specifically, when a vibration motor is used, the vibration phase difference of multiple vibration motors can be used to generate vibration with a sense of direction guidance, so that the finger can feel the pulse vibration with directional kinetic energy feedback when squeezing the key, and each vibration sense has a corresponding relationship with the first control instruction, so that the user can clearly perceive the sense of control direction. When an ultrasonic generator is used, the vibration phase difference of multiple ultrasonic generators can be used to generate a tactile sliding sense in the same direction, so that the finger surface nervous system can perceive the tactile feedback with a sense of direction, and the frequency difference of the ultrasonic generator can also be used to generate difference frequency vibration. When a discharge electrode is used, the discharge time difference of multiple discharge electrodes can be used to generate a weak electrical stimulation of position change on the finger surface, thereby generating stimulation feedback of a sense of direction, so that the user can perceive the direction of the vector operation.

[0057] Further optionally, the first control instruction is used to set the size of the working parameters of the personal cleaning and care device; controlling the feedback module to generate a physical feedback signal according to the first control instruction includes: adjusting the strength of the physical feedback signal according to the direction of change of the working parameters corresponding to the first control instruction.

[0058] Specifically, the strength of the physical feedback signal can also be associated with the direction of change of the set working parameter corresponding to the first control instruction, so that the user can perceive the parameter change. For example, when a certain working parameter is set to be larger and larger, the physical feedback signal can be gradually strengthened, and when a certain working parameter is set to be smaller and smaller, the physical feedback signal can be gradually weakened. When a certain working parameter is set to reach a limit, the physical feedback signal of the current intensity can be continued for a period of time and then stopped. When a vibration motor or ultrasonic generator is used, different force feedback senses can be generated by controlling its frequency and intensity. When a discharge electrode is used, different force feedback senses can be generated by controlling its voltage.

[0059] The technical solution provided by the embodiment of the present invention is that the personal cleaning and care device includes a multi-function button, which includes an elastic protrusion and a force vector sensor arranged at the bottom of the elastic protrusion. First, a vector pressure signal of the force projection of the elastic protrusion on a preset reference plane is measured based on the force vector sensor, and then a first control instruction with a directional characteristic is generated according to the vector pressure signal to control the operation of the personal cleaning and care device according to the first control instruction. By using the elastic characteristic to measure the vector pressure signal of the user's force on the specified plane, and combining the directional characteristic to generate the corresponding control instruction, different control functions can be realized on the same button based on different directions. At the same time, based on the judgment of the force direction, the rotation operation of the traditional multi-function button is avoided, the button wear is reduced, and it is easier to achieve a better waterproof effect to meet the waterproof requirements of the personal cleaning and care device.
