Technical Field

[0001] This invention relates to the field of instrument technology, specifically to a self-adjusting method, device, and repair instrument for instrument usage modes. Background Technology

[0002] With increasing health awareness and a growing number of people experiencing sub-health due to the fast pace of modern life, the demand for home-use health care devices has surged. Home-use repair devices, such as microcurrent beauty repair devices, are becoming increasingly popular due to their ease of use. However, current repair devices often lack the ability to recognize usage methods (usage scenarios and postures) and cannot automatically adjust usage modes. Users must manually adjust these modes, which is inconvenient in certain scenarios, such as underwater or standing use, leading to a poor user experience. Summary of the Invention

[0055] In the description of this invention, it should be noted that the flowcharts shown in the accompanying drawings are merely illustrative and do not necessarily include all contents and operations / steps, nor do they necessarily have to be performed in the described order. For example, some operations / steps can be broken down, combined, or partially merged, so the actual execution order may change depending on the actual situation.

[0056] This invention provides a self-adjusting method for instrument usage modes. This self-adjusting method can be applied to instrument repair, and also to electronic devices, including mobile terminals, computers, smartphones, tablets, laptops, desktop computers, or PDAs. The functions implemented by the self-adjusting method provided in this invention can be achieved by the processor of the repair instrument or electronic device calling a computer program, which can be stored in a memory or computer storage medium.

[0057] See Figure 1 As shown in the figure, this embodiment provides a self-adjustment method for an instrument usage mode, including the following steps S101 to S104.

[0058] S101, acquire the acceleration from the two- or three-axis sensors located on the left and right sides of the instrument;

[0059] S102, acquire the electrical parameter values ​​of five conductive sensors respectively set at the front left, front right, center left, center right and center positions of the instrument;

[0060] S103, Identify the instrument’s usage method based on acceleration or electrical parameter values, including at least one of leg clamp usage, seated usage, and standing usage;

[0061] S104, switch to the corresponding usage mode according to the usage method.

[0062] In step S103, identifying the instrument's usage method based on acceleration or electrical parameter values ​​specifically includes:

[0063] If one axis of a triaxial sensor has a positive acceleration and the other triaxial sensor has a negative acceleration, it is identified as being used as a leg clamp; otherwise, it is identified as not being used as a leg clamp.

[0064] If the electrical parameter values ​​of the three conductive sensors (left center, right center, and center) are all within the first preset electrical parameter value range, and the electrical parameter values ​​of the two conductive sensors (left front and right front) are all within the second preset electrical parameter value range, the device is identified as being used in a seated position; otherwise, it is identified as being used in a non-seated position. In a specific embodiment, the electrical parameter values ​​of the three conductive sensors (left center, right center, and center) can all be less than the first preset electrical parameter threshold, and the electrical parameter values ​​of the two conductive sensors (left front and right front) can all be less than the second preset electrical parameter threshold. In a preferred embodiment, the first preset electrical parameter threshold is less than the second preset electrical parameter threshold.

[0065] In another embodiment, the electrical parameter values ​​of the three conductive sensors (left center, right center, and center) are all greater than a first preset electrical parameter threshold, and the electrical parameter values ​​of the two conductive sensors (left front and right front) are both greater than a second preset electrical parameter threshold. In a preferred embodiment, the first preset electrical parameter threshold is greater than the second preset electrical parameter threshold.

[0066] When the electrical parameter is resistance / voltage, the electrical parameter values ​​of the three conductive sensors (left center, right center, and center) are all less than the first preset resistance value / first preset voltage value, and the electrical parameter values ​​of the two conductive sensors (left front and right front) are all less than the second preset resistance value / second preset voltage value. When the electrical parameter is current, the electrical parameter values ​​of the three conductive sensors (left center, right center, and center) are all greater than the first preset current value, and the electrical parameter values ​​of the two conductive sensors (left front and right front) are all greater than the second preset current value. For example, if the voltage of the three conductive sensors (left center, right center, and center) is less than 10mV, and the electrical parameter values ​​of the two conductive sensors (left front and right front) are less than 30mV, this is considered a sitting posture. Alternatively, if the current of the three conductive sensors (left center, right center, and center) is greater than 5mA, and the electrical parameter values ​​of the two conductive sensors (left front and right front) are greater than 1mA, this is also considered a sitting posture. Essentially, this is because the pressure detected by the three conductive sensors (left center, right center, and center) is greater than a certain threshold, and the electrical parameters of the two conductive sensors (left front and right front) are also greater than a certain threshold. Even better, the system further determines the posture by checking that the pressure detected by the three conductive sensors (left center, right center, and center) is greater than the pressure detected by the two conductive sensors (left front and right front). Specifically, when the electrical parameter is resistance or voltage, the electrical parameter values ​​of the three conductive sensors are less than the electrical parameter values ​​of the two conductive sensors (left front and right front); when the electrical parameter is current, the electrical parameter values ​​of the three conductive sensors are greater than the electrical parameter values ​​of the two conductive sensors (left front and right front).

[0067] If the electrical parameter values ​​of the two conductive sensors (left center and right center) are both within the first preset electrical parameter value range, and the electrical parameter values ​​of the three conductive sensors (center, left front, and right front) are all within the second preset electrical parameter value range, it is identified as standing use; otherwise, it is identified as non-standing use. In one specific embodiment: the electrical parameter values ​​of the two conductive sensors (left center and right center) may be less than the first preset electrical parameter value range, and the electrical parameter values ​​of the three conductive sensors (center, left front, and right front) may be less than the second preset electrical parameter threshold. In a preferred embodiment, the first preset electrical parameter threshold is less than the second preset electrical parameter value.

[0068] In another embodiment, the electrical parameter values ​​of the two conductive sensors at the left center and right center are both greater than a first preset electrical parameter value range, and the electrical parameter values ​​of the three conductive sensors at the center, left front, and right front are all greater than a second preset electrical parameter threshold. In a preferred embodiment, the first preset electrical parameter threshold is greater than the second electrical parameter threshold.

[0069] Electrical parameters include, but are not limited to, the following: resistance, voltage, current, capacitance, or inductance values.

[0070] Specifically, each conductive sensor is individually connected to a power source, and the conductive sensor can convert the pressure signal into a resistance signal, current signal, voltage signal, or capacitance signal for output.

[0071] Conductive sensors can also be connected in series to determine the resistance or voltage change of each sensor using a series voltage divider method. For example, conductive sensors may contain deformable conductive materials; deformation of conductive rubber causes changes in resistance or voltage. Alternatively, the change in resistance or voltage can be determined by variations in the gap between the conductive layer and the pressure-sensitive layer, while the pressure-sensitive layer itself remains unchanged (e.g., a carbon film pressure-sensitive layer). Higher pressure results in lower resistance and voltage of the conductive sensor. Alternatively, a piezoresistive and voltage-dividing resistor combination can be used. The voltage across the voltage-dividing resistor is collected to identify pressure changes; higher pressure results in lower resistance and voltage across the piezoresistive resistor, while higher voltage across the voltage-dividing resistor.

[0072] Conductive sensors can also be connected in parallel to determine the resistance or current change of each sensor by using parallel current division. The greater the pressure, the lower the resistance of the conductive sensor and the greater the current.

[0073] Furthermore, when the electrical parameter is resistance or voltage, the electrical parameter values ​​of the three conductive sensors in the left center, right center, and center position are all less than the electrical parameter values ​​of the two conductive sensors in the left front and right front positions; when the electrical parameter is current, the electrical parameter values ​​of the three conductive sensors in the left center, right center, and center position are all greater than the electrical parameter values ​​of the two conductive sensors in the left front and right front positions.

[0074] The self-adjustment method for the instrument's usage mode further includes providing at least one prompt, including visual, verbal, and tactile, when the instrument is identified as being used with its legs clamped, in a sitting position, or standing.

[0075] Specifically, after identifying the device's usage mode, the user can be informed of the current mode of use through at least one of visual, voice, and tactile cues. If an incorrect mode is identified, the user can promptly turn it off or manually adjust it to the correct usage mode.

[0076] The self-adjustment method for the instrument's usage mode further includes: S105, which further includes: outputting a microcurrent for leg clamp use when switching to leg clamp usage mode; outputting a microcurrent for sitting use when switching to sitting usage mode; and outputting a microcurrent for standing use when switching to standing usage mode.

[0077] Furthermore, the self-adjusting method for the instrument's usage mode also includes: stopping the output of microcurrent when the instrument is identified as not being used with its legs clipped, not being used in a sitting position, or not being used while standing. That is, if it is identified as not being used with its legs clipped, not being used in a sitting position, or not being used while standing, it is determined that the instrument is not currently in use, and the output of microcurrent is stopped to prevent the instrument from wasting power and causing product damage due to idling.

[0078] See Figure 2As shown, for instruments that can be used underwater, before acquiring the acceleration from the two or three-axis sensors located on the left and right sides of the instrument, the following steps are also included:

[0079] Obtain the electrical parameter values ​​output by the water detection circuit set on the instrument;

[0080] If the voltage value is greater than the third preset electrical parameter threshold, it is identified as being used underwater; otherwise, it is identified as being used outside of underwater.

[0081] Correspondingly, the self-adjustment method for the instrument's usage mode further includes: when it is identified as being used underwater and in a leg-clamp position, switching to the underwater leg-clamp usage mode and outputting an underwater leg-clamp usage microcurrent; when it is identified as being used outside of underwater but in a leg-clamp position, switching to the above-water leg-clamp usage mode and outputting an above-water leg-clamp usage microcurrent; when it is identified as being used underwater and in a sitting position, switching to the underwater sitting position usage mode and outputting an underwater sitting position usage microcurrent; when it is identified as being used outside of underwater but in a sitting position, switching to the above-water sitting position usage mode and outputting an above-water sitting position usage microcurrent; when it is identified as being used underwater and in a standing position, switching to the underwater standing position usage mode and outputting an underwater standing position usage microcurrent; and when it is identified as being used outside of underwater but in a standing position, switching to the above-water standing position usage mode and outputting an above-water standing position usage microcurrent.

[0082] In addition to the above-mentioned usage mode recognition, usage mode reminder and automatic usage mode adjustment, the self-adjustment method of the instrument usage mode in this embodiment also includes automatic gear adjustment based on the movement of a person's legs or feet, solving the problem that it is inconvenient to adjust by hand when using it in a standing or sitting position, and further improving the user experience.

[0083] Specifically, the self-adjustment method for the instrument's usage mode also includes:

[0084] When using the leg-clamping mode, if a leg is detected clamping briefly, the control will increase the intensity. If, within a preset time, the electrical parameter value of either the left or right conductive sensor is first greater than a first preset electrical parameter threshold and then less than a first preset electrical parameter threshold, it is recognized as a foot press / lifting down. Alternatively, if, within a preset time, the electrical parameter value of either the left or right conductive sensor is first less than a first preset electrical parameter threshold and then greater than a first preset electrical parameter threshold, it is recognized as a foot press / lifting down.

[0085] If the threshold is reached, it will be identified as stepping on / lifting the leg and pressing down once;

[0086] When used in seated mode, if a foot press / leg lift is detected, the control will increase the speed; if the electrical parameter value of the left or right conductive sensor is first greater than the first preset electrical parameter threshold and then less than the first preset electrical parameter threshold within a preset time, it is identified as a foot press / leg lift; or, if the electrical parameter value of the left or right conductive sensor is first less than the first preset electrical parameter threshold and then greater than the first preset electrical parameter threshold within a preset time, it is identified as a foot press / leg lift.

[0087] When used in standing mode, if a foot step is detected, the control will increase the speed. If the electrical parameter value of the left-center conductive sensor or the right-center conductive sensor is first greater than the first preset electrical parameter threshold and then less than the first preset electrical parameter threshold within a preset time, it is recognized as a foot step. Alternatively, if the electrical parameter value of the left-center conductive sensor or the right-center conductive sensor is first less than the first preset electrical parameter threshold and then greater than the first preset electrical parameter threshold within a preset time, it is recognized as a foot step.

[0088] The following will use an instrument that can be used underwater as an example to explain in detail the above-mentioned method of identifying usage.

[0089] (1) The water detection circuit (including the positive and negative power supply terminals and two electrode plates, etc.) located inside the instrument is connected to two conductive silicone rubbers on the instrument surface via two water detection electrode plates (one as the positive electrode plate and the other as the negative electrode plate). When the two conductive silicone rubbers come into contact with different media, the voltage value is recorded as V. m The preset voltage threshold for identifying ordinary tap water is denoted as V. th When the contact voltage value satisfies V m Greater than or equal to V th At that time, it is identified as being used underwater. It should be noted that the V value can be adjusted according to the specific settings. th The size, such as V th The voltage is set slightly lower than the voltage required for contact with ordinary tap water, so that as long as the contact voltage meets the V requirement... m Greater than V th If it is used underwater, it is identified as being used on water; otherwise, it is identified as being used on water.

[0090] (2) See Figure 3 The diagram shows the distribution of two triaxial sensors (the first triaxial sensor and the second triaxial sensor) fixed horizontally inside the instrument, one on each side. When the instrument is laid flat, the three axes are aligned with the positive X-axis pointing forward, the positive Y-axis pointing to the left, and the positive Z-axis pointing upward.

[0091] When the instrument is used in different scenarios, the triaxial sensor can be used to detect the instrument's attitude and provide acceleration values ​​in the X, Y, and Z directions. The left triaxial sensor (the first triaxial sensor) is denoted as a. xm1 a ym1 a zm1 The right triaxial sensor (the second triaxial sensor) is denoted as a. xm2 a ym2 a zm2 Real-time acquisition of a from two triaxial sensors (left and right). xm a ym a zm , and the preset acceleration threshold a th By comparing, you can determine whether it is suitable for use with a leg clamp.

[0092] When the leg clamp is in use, the instrument is turned outwards to clamp the thigh. The left triaxial sensor shows positive acceleration along the y-axis, while the acceleration along the x and z axes is approximately zero. At this time, a... ym1 >a th a xm1 th ,a zm1 th The right triaxial sensor exhibits negative acceleration along the y-axis, while the acceleration along the x and z axes is approximately zero. At this point, a... ym2 <-a th a xm1 th ,a zm1 th It is identified as a leg clamp for use;

[0093] When the leg clamp is used improperly, the instrument flips inward (folding the outer surface of the instrument inward), and the left triaxial sensor experiences negative acceleration in the y-axis direction. At this time, a... ym1 <-a th The right triaxial sensor has a positive acceleration in the y-axis direction, at which time a ym2 >a th It is not recognized as a leg clamp.

[0094] It should be noted that, in addition to determining whether the acceleration on the y-axis is positive or negative, the acceleration on the x-axis or z-axis can also be determined based on the orientation of the triaxial sensor. That is, the positive or negative acceleration is determined for one of the three axes, and the acceleration on the other two axes is determined to be close to 0.

[0095] Furthermore, when used in a seated or foot-operated position, the repair device is in a flat position. At this time, the two- and three-axis sensors exhibit negative acceleration along the z-axis, while the acceleration along the x and y axes is approximately zero. In this state, a... zm1 <-a th ,a zm2 <-a th ,|a​​​​xm1 | th ,|a zm1 | th ,|a xm2 | th ,|a zm2 | th Under these conditions, a conductive sensor can then be used to distinguish between sitting and foot use.

[0096] It should be noted that, in addition to determining whether the acceleration in the z-axis direction is negative, the x-axis or y-axis acceleration can also be determined based on the placement orientation of the three-axis sensor. That is, negative acceleration is determined for one of the three axes, and the acceleration of the other two axes is determined to be close to 0.

[0097] (3) See Figure 4 In this embodiment, the conductive sensor is configured as a conductive film. Specifically, five conductive films are placed inside the instrument: the first conductive film is placed at the front left, the second at the front right, the third at the center left, the fourth at the center right, and the fifth at the center. The resistance value of each conductive film is monitored in real time and denoted as R. m1 R m2 R m3 R m4 R m5 .

[0098] See diagram of pressure in normal sitting posture. Figure 5 As shown, the pressure is relatively high at the hip bone. Figure 5 The numbers in the diagram represent pressure values. Higher pressures are found at the third, fourth, and fifth conductive films, while lower pressures are found at the first and second conductive films. Higher pressure corresponds to lower resistance values, and vice versa. When the resistance value at the third, fourth, and fifth conductive films is lower than the first preset resistance threshold R... th1 The resistance values ​​at the first and second conductive films are lower than the second set resistance threshold R. th2 Time (R) th1 <R th2 (This is a character that is used in a seated position.)

[0099] When used standing up, the third and fourth conductive films detect pressure, at which point R... m3 <R th1 R m4 <R th1 If the standing (foot) position is inaccurate, and only the first and second conductive films, the first and fourth conductive films, or the second and third conductive films detect pressure, it will not be considered as standing use.

[0100] ​​​​(4) Based on the above identification, automatic switching of microcurrent output is achieved. For example, if the instrument is powered on and lying flat, and no one is using it, the conductive membrane does not detect pressure, so the instrument does not output microcurrent; until someone stands on it, which is suitable for standing use, the instrument outputs microcurrent in foot mode; after the person leaves, the conductive membrane does not detect pressure again, and the instrument stops outputting microcurrent; then the instrument is folded outwards and used as a leg clamp, and the triaxial sensor determines that it is suitable for leg clamp use, so it outputs microcurrent in leg mode. Thus, the instrument in this embodiment can automatically identify different usage parts and scenarios and automatically switch microcurrent output.

[0101] (5) Utilizing a conductive film to achieve gear shifting. When standing, one foot press increases the gear, and two consecutive foot presses decrease the gear. When seated, one leg lift and downward press increases the gear, and two consecutive leg lifts and downward presses decrease the gear. In both usage modes, foot pressing and leg lifting cause changes in the resistance of the conductive film. Lifting the foot / leg decreases the pressure and increases the resistance, i.e., R... m3 >R th1 Or R m4 >R th1 When it is lowered, the pressure increases and the resistance decreases, i.e., R m3 <R th1 Or R m4 <R th1 These two actions are recognized as one valid foot pedal / leg lift and press. When using the leg clamp, clamping the legs once (slightly opening the legs and then bringing them together is one clamping) indicates increasing the gear, and clamping twice in succession indicates decreasing the gear. The two actions of opening and then bringing the legs together increase the pressure and decrease the resistance when clamping, i.e., R m3 <R th1 Or R m4 <R th1 When the pressure decreases during relaxation, the resistance increases, i.e., R m3 >R th1 Or R m4 >R th1 These two actions are identified as a valid clamping action; the above method is used to achieve intelligent control of adding or subtracting microcurrent levels.

[0102] Table 1 below shows the voltage (converted to a microcurrent), operating frequency, and operating time interval of the instrument output to the human body in standing, sitting, and leg-clamping modes during non-underwater and underwater use in one embodiment. As can be seen from Table 1, the voltage for non-underwater use is greater than the voltage for underwater use, which can prevent the possibility of electric shock due to excessive voltage during underwater use.
