[0042] The specific implementation of the present application is further described below with reference to the accompanying drawings.

[0043] It is easy to understand that according to the technical solution of the present application, without changing the essential spirit of the present application, a variety of structural modes and implementation modes that can be replaced by those skilled in the art can be replaced with each other. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the present application, and should not be regarded as the entirety of the present application or as a limitation or restriction on the technical solution of the application.

[0044] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may change accordingly according to their different positions and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0045] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above-mentioned in this application can be understood according to the specific circumstances.

[0046] The skin impedance acquisition method of the beauty instrument in the embodiment of the present application is as follows: Figure 1 Shown, including

[0047] Step S101: acquiring the real-time movement acceleration of the beauty instrument according to a preset collection time interval, and determining the movement distance data of the beauty instrument on the skin plane coordinate system within the preset collection time;

[0048] Step S102: When the moving distance data meets a preset distance condition, skin impedance data is obtained.

[0049] The beauty instrument using the embodiment of the present application is equipped with an acceleration sensor, and the real-time movement acceleration is obtained once at a preset collection time interval. Specifically, the acceleration sensor can be installed at any position of the beauty instrument body, and the detected real-time movement acceleration data is based on the three-dimensional coordinate system of the beauty instrument body. For the convenience of use, the electrode head of the beauty instrument is generally tilted on the body. Therefore, the real-time movement acceleration detected by the acceleration sensor needs to be converted to the skin plane coordinate system, and then the movement distance data of the beauty instrument on the skin plane coordinate system is determined.

[0050] like Figure 2 As shown, the three-dimensional coordinate system of the beauty instrument body is the XYZ coordinate system shown in the figure, the angle between the contact plane A between the electrode head and the skin and the Y axis is α, and the angle between the contact plane A between the electrode head and the skin is β, and the skin plane coordinate system is set on the contact plane A between the electrode head and the skin. Step S101 collects the real-time movement acceleration based on the XYZ coordinate system, and determines the movement distance data of the beauty instrument on the skin plane coordinate system within each preset collection time according to the positional relationship between the XYZ coordinate system and the contact plane A between the electrode head and the skin.

[0051] In step S102, when the moving distance data meets the preset distance condition, the skin impedance data is obtained. For example, when the moving distance data on the skin plane coordinate system within the preset acquisition time of the beauty instrument is greater than or equal to the preset distance, the skin impedance data is obtained. And after each acquisition of the skin impedance data, the process returns to step S101 to continue to collect the real-time movement acceleration of the beauty instrument to obtain the next skin impedance data.

[0052] The embodiment of the present application determines the movement distance data of the beauty instrument on the skin plane by collecting the real-time movement acceleration of the beauty instrument, and obtains the current skin impedance data when the movement distance data meets the preset distance condition, thereby ensuring that the impedance data at different positions on the skin can be collected, avoiding repeated collection of impedance data at the same position, thereby improving the accuracy of the impedance data, and also constructing a skin impedance map through the impedance data at different positions, thereby providing more accurate reference data for the radio frequency output of the beauty instrument.

[0053] In one embodiment, Figure 3 A skin plane coordinate system on the contact plane A between the electrode head and the skin is shown, wherein the skin plane coordinate system includes a first coordinate axis X1 and a second coordinate axis Y1 that are perpendicular to each other, and the moving distance data includes a first moving distance of the beauty device in the direction of the first coordinate axis and a second moving distance of the beauty device in the direction of the second coordinate axis.

[0054] As an example, the position of the beauty instrument at the initial moment is the origin O1. After a preset collection time, the beauty instrument moves to point P shown in the figure, and the moving distance data includes a first moving distance p1 and a second moving distance p2.

[0055] Specifically, the preset distance condition includes

[0056] The first moving distance is greater than or equal to a preset distance threshold, or

[0057] The second moving distance is greater than or equal to a preset distance threshold.

[0058] In an embodiment of the present application, when the movement distance of the beauty instrument along one of the coordinate axes within a preset collection time is greater than or equal to a preset distance threshold, skin impedance data is acquired to collect skin impedance data at different positions in the area.

[0059] In one of the embodiments, the skin plane coordinate system includes a first coordinate axis and a second coordinate axis that are perpendicular to each other;

[0060] The skin impedance data includes coordinates and corresponding skin impedance values, and the coordinates include a first coordinate value and a second coordinate value.

[0061] The skin impedance data in the embodiment of the present application includes the coordinates of the beauty instrument in the skin plane coordinate system at the current moment and the corresponding skin impedance value. Positioning is performed through coordinates to avoid repeated collection of skin impedance values ​​and facilitate the construction of a skin impedance map.

[0062] In one embodiment, when all the collected skin impedance data include at least a first preset number of different first coordinate values ​​and at least a second preset number of different second coordinate values, then

[0063] A regional impedance value is determined from all skin impedance values.

[0064] The embodiment of the present application can uniformly collect skin impedance values ​​at different positions within a certain range, thereby determining the regional impedance value of the region and improving the detection accuracy of the regional impedance value. The first preset number and the second preset number are greater than or equal to 3, and the first preset number can be equal to the second preset number.

[0065] For example, the first preset number and the second preset number are both set to 5. Figure 3 An example of the coordinates of the collected skin impedance data is shown. The data are collected from point P to point Q in sequence according to the illustrated path. If the conditions of 5 different first coordinate values ​​and 5 different second coordinate values ​​are met, the collection of skin impedance values ​​is stopped at this time. The regional impedance value is determined based on the collected 15 skin impedance values, specifically including:

[0066] First, the standard deviation of all skin impedance values ​​is calculated. If the standard deviation is less than a preset standard deviation threshold (preferably, the preset standard deviation threshold is 10), then

[0067] After all skin impedance values ​​are sorted according to size, all the skin impedance values ​​are separated into two groups of impedance value arrays with the same length; if the number of skin impedance values ​​is odd, the skin impedance values ​​are divided before and after the median after being sorted from small to large. For example, after all 15 skin impedance values ​​are sorted from small to large, the 1st to 8th skin impedance values ​​are used as one group of impedance value arrays, and the 8th to 15th skin impedance values ​​are used as another group of impedance value arrays.

[0068] Then, a group of impedance value arrays with smaller ranges are selected as target impedance value arrays, and the average value of the target impedance value arrays is calculated as the regional impedance value.

[0069] If the standard deviation is greater than or equal to a preset standard deviation threshold, the collected skin impedance data is cleared and data collection is performed again.

[0070] In one embodiment, the step of determining the moving distance data of the beauty instrument on the skin plane coordinate system within a preset acquisition time specifically includes:

[0071] Determine the movement speed of the beauty instrument according to the real-time movement acceleration;

[0072] Projecting the moving speed of the beauty instrument onto a skin plane coordinate system to determine the projected moving speed of the beauty instrument on the skin plane coordinate system;

[0073] According to the projection moving speed, the moving distance data of the beauty instrument on the skin plane coordinate system within a preset acquisition time is determined.

[0074] Specifically, the real-time mobile acceleration collected by the acceleration sensor includes the acceleration in the three coordinate axis directions in the three-dimensional coordinate system of the fuselage. The moving speed of the beauty instrument is determined based on the real-time mobile acceleration. The moving speed of the beauty instrument also includes the moving speed in the three coordinate axis directions in the three-dimensional coordinate system of the fuselage.

[0075] like Figure 2 As shown, the beauty instrument moving speed includes the X-axis speed V X , Y axis speed V Y and Z-axis speed V Z Based on the positional relationship between the three-dimensional coordinate system of the fuselage and the plane coordinate system of the skin, the moving speed of the beauty instrument is projected onto the plane coordinate system of the skin to obtain the projected moving speed of the beauty instrument on the plane coordinate system of the skin, including

[0076] X1 axis speed V X1 =V X ;

[0077] Y1 axis speed V Y1 =V Z *cosβ+V Y *cosα.

[0078] Then, the moving distance data of the beauty instrument on the skin plane coordinate system within the preset acquisition time is calculated according to the projection moving speed, including

[0079] The first moving distance L1 = V X1 *T, second moving distance L2 = V Y1 *T;

[0080] Where T is the preset acquisition time.

[0081] In one embodiment, determining the movement speed of the beauty instrument according to the real-time movement acceleration specifically includes:

[0082] Subtract the movement acceleration at the previous moment from the current movement acceleration to determine a first acceleration change;

[0083] Subtract the current movement acceleration from the movement acceleration at the next moment to determine a second acceleration change;

[0084] The moving speed of the beauty instrument is determined according to the first acceleration change amount and the second acceleration change amount.

[0085] Specifically, the current moving acceleration includes the X-axis acceleration a X1 , Y-axis acceleration a Y1 and Z-axis acceleration a Z1 ; The movement acceleration at the previous moment includes the X-axis acceleration a X0 , Y-axis acceleration a Y0 and Z-axis acceleration a Z0 ; The moving acceleration at the next moment includes the X-axis acceleration a X2 , Y-axis acceleration a Y2 and Z-axis acceleration a Z2 .

[0086] Calculating the first acceleration change includes

[0087] X-axis first acceleration change Δa X1 =a X1 -a X0 ;

[0088] Y-axis first acceleration change Δa Y1 =a Y1 -a Y0 ;

[0089] The first acceleration change of Z axis Δa Z1 =aZ1 -a Z0 .

[0090] Calculating the second acceleration change includes

[0091] X-axis second acceleration change Δa X2 =a X2 -a X1 ;

[0092] Y-axis second acceleration change Δa Y2 =a Y2 -a Y1 ;

[0093] Z-axis second acceleration change Δa Z2 =a Z2 -a Z1 .

[0094] Based on the integration idea of ​​converting acceleration into velocity, the moving speed of the beauty instrument is determined according to the acceleration change and the actual acceleration.

[0095] X-axis speed

[0096] Y-axis speed

[0097] Z-axis speed

[0098] Wherein, T is the preset collection time.

[0099] In one embodiment, the obtaining of the real-time movement acceleration of the beauty instrument specifically includes:

[0100] Acquire a reference acceleration value of the beauty instrument at a set frequency, wherein the reference acceleration value includes X-axis acceleration, Y-axis acceleration, and Z-axis acceleration;

[0101] After continuously acquiring a third preset number of reference acceleration values, an X-axis acceleration average value, a Y-axis acceleration average value, and a Z-axis acceleration average value of the third preset number of reference accelerations are respectively calculated as the current movement acceleration.

[0102] The embodiment of the present application continuously collects a third preset number of reference acceleration values, calculates the average acceleration values ​​of the X-axis, Y-axis and Z-axis respectively, and uses them as the current movement acceleration, thereby improving the accuracy of data collection.

[0103] It should be noted that the aforementioned preset acquisition time is related to the set frequency and the third preset number. As an example, the set frequency is set to 4 milliseconds / time, and the third preset number is set to 4, then four reference acceleration values ​​are continuously obtained, and the average value of the X-axis acceleration, the average value of the Y-axis acceleration, and the average value of the Z-axis acceleration are calculated as the current moving acceleration, and at this time the preset acquisition time is 4 milliseconds / time multiplied by 4 times, which is equal to 16 milliseconds.

[0108] Step S402: subtract the movement acceleration at the previous moment from the current movement acceleration to determine a first acceleration change;

[0109] Step S403: subtract the current movement acceleration minus the gravity acceleration from the movement acceleration at the next moment to determine the second acceleration change;

[0110] Step S404: determining the moving speed of the beauty instrument according to the first acceleration change amount and the second acceleration change amount;

[0111] Step S405: Projecting the movement speed of the beauty instrument onto the skin plane coordinate system to determine the projection movement speed of the beauty instrument on the skin plane coordinate system;

[0115] Step S409: Calculate the standard deviation of all skin impedance values. If the standard deviation is less than a preset standard deviation threshold,

[0116] Step S410: after sorting all skin impedance values ​​according to their sizes, all the skin impedance values ​​are separated into two groups of impedance value arrays with the same length;
