[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It will be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some but not all structures related to the present application are shown in the drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0024] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] A beauty instrument is an instrument that adjusts and improves the skin according to the physiological functions of the human body. It has multiple functions such as whitening and skin rejuvenation. At present, most beauty instruments on the market include an operating head and a light or electricity generating circuit. Among them, the operating head is mainly in contact with the human skin, and there is an output surface of the light or electricity generating circuit on the operating head. After the light or electricity generated by the light or electricity generating circuit reaches the skin, it can process the skin and achieve the effect of improving the skin.

[0026] In addition, the beauty instrument may also include a skin contact element, a cooling element, a heat dissipation element, a vibration component, etc. Among them, the skin contact element can be sapphire or an electrode group. When the cooling element is heating, the skin contact element is heated up, and after the skin contact element contacts the skin, the skin feels comfortable and not cold; when the cooling element is cooling, the skin contact element is cooled down to reduce the skin surface temperature when the skin is overheated.

[0027] The function of the vibration component is to vibrate the cells at the bottom of the skin, thereby achieving the effect of skin care and improving cell activity. In addition, the vibration frequency of the vibration component is high, and the energy contained is relatively large, which can effectively massage the skin cells and break the nutrients in the skin care products into small molecules so that the skin can absorb them better.

[0028] It should be noted that there are many types of beauty devices, such as radio frequency beauty devices, microcurrent beauty devices, LED light beauty devices, etc. Some beauty devices need to be used with gel, while some beauty devices can be used directly without gel. However, when using microcurrent beauty devices, since the surface of human skin has its own resistance, it is generally necessary to use a conductive medium to help the microcurrent effectively conduct into the deep layer of the skin and play a role. In addition, when using a beauty device with gel, there are many things to pay attention to. If the user does not operate it in a standardized manner, it is easy to cause unnecessary consumption of the beauty device or damage the user's skin.

[0029] Therefore, in order to avoid unnecessary consumption of the beauty instrument or damage to the user's skin, the present application sets a current detection circuit in the beauty instrument to detect the current value between the positive and negative electrodes in real time, and judge whether the gel is used when the beauty instrument is used, and whether the gel used is appropriate. Figure 1 , Figure 1 It is a structural schematic diagram of an embodiment of a beauty instrument provided in the present application. The beauty instrument 130 includes a pulse or microcurrent generating circuit 131, at least one group of positive and negative electrodes 132 electrically connected to the pulse or microcurrent generating circuit 131, a current detection circuit 133 and a controller 134.

[0030] Among them, the pulse or microcurrent generating circuit 131 generates a pulse current or a microcurrent, and transmits the pulse current or the microcurrent to the positive and negative electrodes through electrical connection; the current detection circuit 133 is connected to at least one group of positive and negative electrodes 132, and then detects the current value between at least one group of positive and negative electrodes 132; the controller 134 connects the current detection circuit 133 and the pulse or microcurrent generating circuit 131, and compares the first current value between the positive and negative electrodes of the beauty instrument at a preset power with the threshold current range, so as to detect whether the positive and negative electrodes are covered with gel, so that after determining whether the positive and negative electrodes are covered with gel, corresponding measures can be taken to adapt to different situations.

[0031] For the specific steps of the method for detecting whether the positive and negative electrodes are covered with gel, please refer to the following examples. Figure 2 , Figure 2 This is a flow chart of the first embodiment of the method for detecting the use of a beauty instrument provided by the present application. The method comprises:

[0032] Step 11: Obtain a first current value between the positive and negative electrodes of the beauty instrument at a preset power.

[0033] The first current value between the positive and negative electrodes can be obtained by means of a current detection circuit or a current sensor.

[0034] The preset power may be a standard power when the beauty device contacts the skin and slides when the positive and negative electrodes are not covered with gel, or other power lower than the standard power to prevent irritation or damage to the user's skin.

[0035] Step 12: Compare the first current value with a first threshold.

[0036] The first threshold is the current range when the positive and negative electrodes are not covered with gel at the preset power. 。 The first threshold may be set manually or obtained by looking up a table.

[0037] Gel is a polymer solution or sol of a certain concentration. It acts as a conductive medium, which is conducive to the flow of electric current and helps the electric current to effectively conduct into the deep layers of the skin and play a role. Generally speaking, gel can include cream, mask or lotion, etc., and the specific choice is based on the actual skin condition of the user.

[0038] Step 13: If the first current value is greater than the first threshold, it is determined that the positive and negative electrodes are covered with gel.

[0039] For example, the first current value obtained is XmA, and the first threshold is [AmA, BmA]. If XmA is greater than BmA, it can be determined that the positive and negative electrodes are covered with gel.

[0040] Step 14: Or if the first current value is within the first threshold, it is determined that the positive and negative electrodes are not covered with gel.

[0041] For steps 12 to 14, assuming that the first current value obtained in step 11 is XmA, and the first threshold is [AmA, BmA], XmA is first compared with AmA, and then XmA is compared with BmA, so as to compare the first current value with the first threshold.

[0042] Specifically, if XmA is greater than AmA but less than BmA, it means that the acquired first current value XmA is within the first threshold [AmA, BmA], and it can be determined that the positive and negative electrodes are not covered with gel at this time.

[0043] If XmA is greater than AmA and greater than BmA, it means that the acquired first current value XmA is greater than the first threshold [AmA, BmA], and it can be determined that the positive and negative electrodes are covered with gel at this time.

[0044] When the current acts directly on human skin, it is difficult for the beauty device to slide on the skin because the skin is relatively dry, and the current generated is very small. The current can generally only rebound on the surface of the human skin, and only a small part of the current can be directly transmitted to the deep layer of the human skin to act. Therefore, the use of current to directly stimulate the skin results in the effect of the beauty device being insignificant. If the current directly contacting the skin is increased to solve the above problem, the user may intuitively feel a stinging pain, and if the beauty device stays on the skin for a long time, it may also cause a thermal effect due to the impedance of the skin, resulting in skin burns.

[0045] Therefore, the present application sets a layer of conductive medium (such as adding gel) between the beauty instrument and the skin. Since gel has a conductive effect, the use of gel is conducive to the flow of current, helps the current to be introduced into the deep layer of the skin, stimulates collagen fibers, and makes the skin tighten and lift; and the gel can maintain the temperature generated by the radio frequency wave in the dermis, reduce the consumption of radio frequency energy in the process of skin tissue transmission, make the heat energy continue to circulate in the dermis, and help collagen regenerate quickly. In other words, the use of gel can help the beauty instrument to play its role, promote the metabolism of human subcutaneous cells, and improve the skin care effect.

[0046] It should be noted that if the positive and negative electrodes are not covered with gel, when the current directly acts on the human skin, the first current value between the positive and negative electrodes is relatively small due to the lack of a conductive medium. However, if the positive and negative electrodes are covered with gel, the first current value between the positive and negative electrodes is relatively large. Because gel is a relatively good conductive medium, the conductivity can be increased by using gel, so when the positive and negative electrodes are covered with gel, the first current value between the positive and negative electrodes is relatively large.

[0047] Therefore, this embodiment can detect whether the positive and negative electrodes are covered with gel based on the relationship between the first current value between the positive and negative electrodes of the beauty instrument at a preset power and the current range when the positive and negative electrodes are not covered with gel at the preset power, so that after determining whether the positive and negative electrodes are covered with gel, corresponding measures can be taken to adapt to different situations.

[0048] In addition, it should be noted that the above steps 13 and 14 do not represent a sequential order.

[0049] Although beauty devices are generally provided with a timed shutdown function, they can automatically shut down within a preset time to reduce the consumption of the beauty device. However, if the energy required by the beauty device is provided by a battery, or the beauty device is not in contact with human skin when in use, and the preset time for automatic shutdown has not been reached, the power of the beauty device will be consumed unnecessarily. Therefore, in some embodiments, after determining that the positive and negative electrodes are covered with gel or determining that the positive and negative electrodes are not covered with gel, it can be further confirmed whether the beauty device moves in close contact with the skin. If it is determined that the beauty device does not move in close contact with the skin, the output value of the cooling power and / or the output size of the positive and negative electrodes can be reduced, or the positive and negative electrodes can be directly controlled not to work to reduce unnecessary consumption of the beauty device.

[0050] When it is determined that the positive and negative electrodes are covered with gel, it can be further determined whether the gel covering the positive and negative electrodes is in contact with human skin. Figure 3 , Figure 3 This is a flow chart of the second embodiment of the method for detecting the use of a beauty device provided by the present application. The method comprises:

[0051] Step 21: Obtain a first current value between the positive and negative electrodes of the beauty instrument at a preset power.

[0052] Step 22: Compare the first current value with a first threshold.

[0053] The first threshold is the current range when the positive and negative electrodes are not covered with gel at a preset power.

[0054] Step 23: If the first current value is greater than the first threshold, it is determined that the positive and negative electrodes are covered with gel.

[0055] Step 24: Compare the first current value with the second threshold.

[0056] The second threshold is the current range when the positive and negative electrodes are covered with gel and in contact with the skin at a preset power.

[0057] Step 25: If the first current value is greater than the second threshold, it is determined that the positive and negative electrodes are covered with gel and the gel does not contact the skin.

[0058] Step 26: Or if the first current value is within the second threshold, it is determined that the positive and negative electrodes are covered with gel and the gel contacts the skin.

[0059] For step 24 to step 26, assuming that the second threshold is [CmA, DmA], based on the first current value XmA and the first threshold [AmA, BmA] obtained in the first embodiment, the first current value is compared with the second threshold.

[0060] Specifically, the first current value XmA is first compared with the minimum value CmA of the second threshold, and then XmA is compared with the maximum value DmA of the second threshold, so as to compare the first current value with the second threshold.

[0061] Exemplarily, if XmA is greater than CmA but less than DmA, it means that the acquired first current value XmA is within the second threshold value [CmA, DmA], and the second threshold value is the current range when the positive and negative electrodes are covered with gel and in contact with the skin under preset power. It can be determined that the positive and negative electrodes are covered with gel and in contact with the skin at this time.

[0062] If XmA is greater than CmA and greater than DmA, it means that the acquired first current value XmA is greater than the second threshold [CmA, DmA], and it can be determined that the positive and negative electrodes are covered with gel and the gel does not contact the skin.

[0063] Because the positive and negative electrodes are covered with gel but the gel does not touch the skin, the current only flows between the gel at the heads of the positive and negative electrodes. However, if the positive and negative electrodes are covered with gel and the gel touches the skin, the area of ​​the gel in contact with the skin will be larger, resulting in smaller current dispersion.

[0064] In addition, it should be noted that the first threshold is the current range when the positive and negative electrodes are not covered with gel at a preset power, and the second threshold is the current range when the positive and negative electrodes are covered with gel and in contact with the skin at a preset power. Since the current when the positive and negative electrodes are not covered with gel is relatively small, the current range of the second threshold is greater than the current range of the first threshold. Moreover, when the first current value obtained is greater than the second threshold, it can be determined that the positive and negative electrodes are covered with gel and the gel is not in contact with the skin. Therefore, it can be concluded that the current value when the positive and negative electrodes are covered with gel and the gel is not in contact with the skin is greater than the current value when the positive and negative electrodes are covered with gel and the gel is in contact with the skin, which is greater than the current value when the positive and negative electrodes are not covered with gel.

[0065] Therefore, this embodiment can detect whether the gel covered by the positive and negative electrodes is in contact with the skin based on the relationship between the first current value between the positive and negative electrodes of the beauty instrument at a preset power and the current range when the positive and negative electrodes are covered with gel and in contact with the skin at the preset power, so that when it is determined that the positive and negative electrodes are covered with gel and are not in contact with the skin, unnecessary consumption of the beauty instrument can be reduced by reducing the output value of the cooling power and / or the output size of the positive and negative electrodes.

[0066] See also Figure 4 , Figure 4 1 is a flow chart of the third embodiment of the method for detecting the use of a beauty device provided by the present application. The method comprises:

[0067] Step 31: Limit the power output of the beauty device.

[0068] The power output of the beauty instrument can be limited by changing the output current when the output voltage is constant, or a power limiter can be used to automatically limit the power output of the beauty instrument.

[0069] Generally, the power output of the beauty instrument is limited when it is turned on.

[0070] Generally, when some beauty devices are just turned on and the mode button or gear button has not been pressed, the beauty devices are in standby mode and the output power is relatively small. This is equivalent to limiting the power of the beauty device before turning on, so that the beauty device outputs a smaller power when the mode button or gear button is not pressed.

[0071] For other beauty devices, they may already output pulse currents corresponding to the default mode keys and gear keys when they are turned on. At this time, in order to prevent irritation or damage to the user's skin, it is necessary to limit the power output of the beauty device when it is turned on, so that the beauty device outputs at a lower power (i.e., the preset power or a power less than the preset power).

[0072] Step 32: Obtain a first current value between the positive and negative electrodes of the beauty instrument at a preset power.

[0073] Among them, the preset power can be the standard power when the beauty device contacts the skin and slides when the positive and negative electrodes are not covered with gel, or it can be a power slightly smaller than the standard power when the beauty device contacts the skin and slides to prevent irritation or damage to the user's skin.

[0074] Step 33: Compare the first current value with a first threshold.

[0075] The first threshold is the current range when the positive and negative electrodes are not covered with gel at a preset power.

[0076] Step 34: If the first current value is greater than the first threshold, it is determined that the positive and negative electrodes are covered with gel.

[0077] Step 35: Compare the first current value with the second threshold.

[0078] The second threshold is the current range when the positive and negative electrodes are covered with gel and in contact with the skin at a preset power.

[0079] Step 36: If the first current value is within the second threshold, it is determined that the positive and negative electrodes are covered with gel and the gel contacts the skin.

[0080] Steps 33 to 36 have the same or similar technical solutions as those in the above embodiment and are not described in detail here.

[0081] Step 37: Remove the power output restriction on the beauty instrument so that the beauty instrument operates in a normal mode, or increase the output power of the beauty instrument.

[0082] Generally, beauty devices include multiple modes, such as cleaning mode, lifting mode, moisturizing mode, ice mode, eye mode, etc. Each mode may also include multiple adjustable gears, such as low gear, medium gear, and high gear. Each mode and each gear has a default usage frequency, power, and current size. The default usage mode is the normal mode.

[0083] For some beauty devices, they may have output pulse currents corresponding to the default mode and gear keys when they are turned on. At this time, in order to prevent irritation or damage to the user's skin, it is necessary to limit the power output of the beauty device so that it outputs at a lower power (that is, the preset power). After detecting the first current value between the positive and negative electrodes at the preset power, and comparing the first current value with the first threshold and the second threshold, and determining that the positive and negative electrodes are covered with gel and the gel contacts the skin, the power output limit of the beauty device is released, so that the beauty device runs at the power corresponding to the normal mode, or the output power of the beauty device at this time is increased.

[0084] Specifically, for example, when the beauty instrument is turned on, if the output power of the beauty instrument is not limited, the beauty instrument directly defaults to outputting at the power of the mid-range lifting mode. In order to prevent irritation or damage to the user's skin, it is necessary to limit the power output of the beauty instrument when it is turned on, so that the beauty instrument outputs at a smaller power (i.e., a preset power or a power slightly smaller than the preset power). After detecting the first current value between the positive and negative electrodes of the beauty instrument at the preset power, and comparing the first current value with the first threshold and the second threshold, and determining that the positive and negative electrodes are covered with gel and the gel contacts the skin, the power output limit of the beauty instrument is released, so that the beauty instrument operates at the power corresponding to the normal mode (i.e., the mid-range lifting mode). In addition, since the preset power is the standard power when the beauty instrument contacts the skin and slides when the positive and negative electrodes are not covered with gel; and after the positive and negative electrodes are covered with gel, when the output voltage remains unchanged, the output power of the beauty instrument will also increase because the current increases. Therefore, it is necessary to release the power output limit of the beauty instrument and increase the output power of the beauty instrument.

[0085] In addition, because the gel does not move when it contacts the skin, it will burn the human skin over a long period of time. At this time, it is also necessary to adjust it by changing the output power of the beauty instrument.

[0086] Therefore, in this embodiment, when it is determined that the positive and negative electrodes are covered with gel and the gel is in contact with the skin, but it is not determined whether the beauty device is sliding, it is necessary to lift the power output limit on the beauty device, so that when it is subsequently determined that the beauty device is in contact with the skin but not sliding, the output power of the beauty device can be changed to avoid the situation where the gel does not move for a long time while in contact with the skin, which may burn the skin.

[0087] See also Figure 5 , Figure 5 1 is a flow chart of a fourth embodiment of the method for detecting the use of a beauty device provided by the present application. The method comprises:

[0088] Step 41: Obtain a first current value between the positive and negative electrodes of the beauty instrument at a preset power.

[0089] Step 42: Compare the first current value with a first threshold.

[0090] The first threshold is the current range when the positive and negative electrodes are not covered with gel at a preset power.

[0091] Step 43: If the first current value is greater than the first threshold, it is determined that the positive and negative electrodes are covered with gel.

[0092] Step 44: Compare the first current value with the second threshold.

[0093] The second threshold is the current range when the positive and negative electrodes are covered with gel and in contact with the skin at a preset power.

[0094] Step 45: If the first current value is within the second threshold, it is determined that the positive and negative electrodes are covered with gel and the gel contacts the skin.

[0095] Step 46: Obtain preset gel usage rules.

[0096] The preset gel usage rules include the frequency of use, the recommended working time for each use and the recommended amount of gel for each use.

[0097] Step 47: According to the mapping relationship between the current value and the amount of gel used, determine the amount of gel covering the positive and negative electrodes corresponding to the first current value.

[0098] Among them, the amount of gel used can be set according to the type of gel and the moisture content of the gel. For example, the type of gel can be classified according to the moisture content of the gel, such as dividing the gel into water emulsion, facial mask and facial cream, etc. Among them, the water content of the water emulsion is relatively high and the thickness is relatively thin, while the water content of the facial cream is relatively low and it is relatively thick.

[0099] For example, under standard operating frequency and working time, the mapping relationship between current value and gel dosage can be as follows:

[0100] The current value is XmA, and the corresponding gel dosage range is m;

[0101] The current value is EmA, and the corresponding gel dosage range is n;

[0102] The current value is FmA, and the corresponding gel dosage range is f.

[0103] Step 48: Determine whether the amount of gel covering the positive and negative electrodes complies with preset gel usage rules.

[0104] For example, by comparing the acquired current value with the current value in the gel usage rule.

[0105] For example, in some embodiments, the following steps may be specifically adopted:

[0106] Step 481: Determine the standard current value corresponding to the recommended gel dosage.

[0107] Step 482: Compare the current first current value with the standard current value.

[0108] For step 481 and step 482, specifically, assuming that the gel is used in a standard amount, the corresponding current value range is EmA. Based on the first current value XmA obtained in the above embodiment 1 and the first current value XmA being greater than the first threshold value [AmA, BmA], it is determined whether the amount of gel covering the positive and negative electrodes meets the preset gel usage rules.

[0109] If the first current value XmA obtained is less than EmA, it means that the amount of gel covering the positive and negative electrodes is insufficient; on the contrary, if the first current value XmA obtained is within the range of EmA, it means that the amount of gel covering the positive and negative electrodes meets the preset gel usage rules.

[0110] Step 49: If the preset gel usage rules are met, the beauty instrument operates in normal mode.

[0111] Step 50: Otherwise, adjust the cooling power or the output size of the positive and negative electrodes to adapt the amount of gel covering the positive and negative electrodes.

[0112] Optionally, when the amount of gel covering the positive and negative electrodes is insufficient, reference may be made to the countermeasures taken when the positive and negative electrodes are not covered with gel.

[0113] For example, the cooling power or the output size of the positive and negative electrodes can be reduced to accommodate the amount of gel covering the positive and negative electrodes.

[0114] For step 49 and step 50, in other embodiments, the specific judgment methods and measures that can be adopted are: judging the relationship between the current first current value and the standard current value, if the current first current value is less than the standard current value, it means that the amount of gel covering the positive and negative electrodes is insufficient, then reducing the output value of the cooling power or the output size of the positive and negative electrodes to adapt the amount of gel covering the positive and negative electrodes.

[0115] Optionally, in other embodiments, it is also possible to determine whether the amount of gel covering the positive and negative electrodes complies with preset gel usage rules based on the mapping relationship between the current value and the gel type.

[0116] For example, under standard working frequency and working time, the mapping relationship between current value and type can be: the current value corresponding to the water lotion is XmA; the current value corresponding to the mask is EmA; and the current value corresponding to the cream is FmA.

[0117] If the gel covering the positive and negative electrodes at this time is a facial mask, and the first current value obtained is XmA, then by looking up the mapping relationship between current value and type, it can be found that when the current value is XmA, the recommended gel is water emulsion, which means that the gel covering the positive and negative electrodes at this time does not comply with the preset gel usage rules. The facial mask used at this time can be replaced with water emulsion to adapt to the current value at this time.

[0118] In addition, since the cream has less water and is more viscous, it is difficult for the beauty instrument to spread the cream on the skin, and it is easy to dry when applied on the skin. Therefore, the current value corresponding to the cream will be relatively small. Therefore, when it is determined that the gel covering the positive and negative electrodes does not meet the preset gel usage rules, the current value can also be changed to adapt to the gel covering the positive and negative electrodes at this time.

[0119] This embodiment determines whether the amount of gel covering the positive and negative electrodes meets the preset gel usage rules by looking up the mapping relationship between the current value and the gel usage. When it is determined that the amount of gel covering the positive and negative electrodes does not meet the preset gel usage rules, the output value of the cooling power and / or the output size of the positive and negative electrodes can be reduced to reduce unnecessary consumption of the beauty instrument or replace the type of gel used at this time.

[0120] In some embodiments, the gel usage rule further includes a correspondence between multiple skin types and the thickness of the gel used. After determining that the positive and negative electrodes are covered with gel and the gel contacts the skin, the following steps may also be included:

[0121] Step 61: Determine the user's skin sensitivity.

[0122] For example, according to the different levels of user's skin sensitivity, the skin is divided into normal, mildly sensitive, moderately sensitive, severely sensitive, etc.

[0123] For the user's skin sensitivity, you can choose a skin detector to test the skin first. The skin detector mainly uses the electrophysiological characteristics of the skin, which will change with the skin's hydration and oil secretion. By measuring the electrophysiological parameters, the moisture, oil, and elasticity index of the skin are obtained, and then compared with the index of each skin type to determine the user's skin type. For example, the user's skin type can be determined based on the amount of oil secretion of the user's skin or the size of the user's pores.

[0124] In other embodiments, a skin quality detection circuit may also be provided in the beauty instrument. The skin quality detection circuit may be connected to a controller to detect the skin quality of the user's skin and further determine the user's skin type.

[0125] Step 62: Determine the user's skin type based on the user's skin sensitivity.

[0126] For example, skin types may include normal skin, dry skin, oily skin, combination skin, and sensitive skin.

[0127] Exemplarily, if the user's skin sensitivity is normal, the skin type may be neutral skin; if the user's skin sensitivity is severely sensitive, the skin type may be sensitive skin.

[0128] Step 63: Look up the correspondence between the skin type and the thickness of the gel used in the gel use rule, and determine the gel thickness corresponding to the user's skin type.

[0129] For example, water lotion is suitable for dry skin, while water lotion, facial mask or facial cream can be used for neutral skin.

[0130] Among them, the gel thickness can be determined according to the type of gel.

[0131] Step 64: Determine whether the gel thickness corresponding to the user's skin type matches the amount of gel covering the positive and negative electrodes corresponding to the first current value.

[0132] For example, the correspondence between skin type and gel type is: dry skin is suitable for using water lotion, and the corresponding current value is XmA; oily skin is suitable for using facial mask, and the corresponding current value is EmA; neutral skin is suitable for using facial cream, and the corresponding current value is FmA.

[0133] If it is determined that the current user's skin type is oily, and the first current value obtained is XmA, then by looking up the correspondence between skin type and gel type, it can be found that when the current value is XmA, it means that the gel covering the positive and negative electrodes is a water emulsion, which is suitable for dry skin. This means that the gel thickness corresponding to the user's skin type does not match the type of gel covering the positive and negative electrodes corresponding to the first current value. Therefore, the gel covering the positive and negative electrodes at this time can be replaced with a facial mask instead of a water emulsion to suit the current user's skin type.

[0134] This embodiment determines whether the gel covering the positive and negative electrodes is suitable for the skin type of the current user by looking up the correspondence between the skin type and the thickness of the gel used in the gel usage rules, so that if the gel is not suitable for the skin type of the current user, the type of gel can be changed in time to improve the user's skin care effect.

[0135] In some embodiments, the beauty instrument may include multiple sets of electrodes. Figure 6 , Figure 6 It is a flow chart of a method for detecting the use of a beauty instrument provided by the present application when the beauty instrument includes two sets of electrodes. The method includes:

[0136] Step 71: Obtain a second current value between the first group of positive and negative electrodes and a third current value between the second group of positive and negative electrodes of the beauty device at a preset power.

[0137] Among them, the second current value between the first group of positive and negative electrodes and the third current value between the second group of positive and negative electrodes can be obtained by means of a current detection circuit or a current sensor.

[0138] The preset power may be a standard power when the beauty device contacts the skin and slides without the positive and negative electrodes being covered with gel.

[0139] Exemplarily, it is assumed that the second current value obtained between the first group of positive and negative electrodes is YmA, and the third current value obtained between the second group of positive and negative electrodes is ZmA.

[0140] Step 72: Compare the second current value and the third current value with the first threshold value respectively.

[0141] The first threshold is the current range when the positive and negative electrodes are not covered with gel at a preset power.

[0142] For example, assuming that the first threshold is [AmA, BmA], the second current value YmA and the third current value ZmA are respectively compared with the minimum value AmA and the maximum value BmA in the first threshold, so as to compare the second current value and the third current value with the first threshold respectively.

[0143] Step 73: If the second current value is greater than the first threshold, it is determined that the first group of positive and negative electrodes are covered with gel.

[0144] Specifically, if the second current value YmA is greater than AmA and greater than BmA, it means that the acquired second current value YmA is greater than the first threshold [AmA, BmA], and it can be determined that the first group of positive and negative electrodes are covered with gel.

[0145] Step 74: Control the first group of positive and negative electrodes to work normally.

[0146] Step 75: If the third current value is within the first threshold, it is determined that the second set of positive and negative electrodes are not covered with gel.

[0147] Specifically, if ZmA is greater than AmA but less than BmA, it means that the acquired third current value ZmA is within the first threshold [AmA, BmA], and it can be determined that the second group of positive and negative electrodes are not covered with gel.

[0148] Step 76: Control the second group of positive and negative electrodes to not work.

[0149] This embodiment arranges multiple groups of electrodes on the beauty instrument, and detects the positive and negative electrode groups covered with gel and the positive and negative electrode groups not covered with gel according to the relationship between the current values ​​between each group of positive and negative electrodes of the beauty instrument at a preset power and the current range when the positive and negative electrodes are not covered with gel at the preset power, so that the positive and negative electrode groups covered with gel can be controlled to work, while the positive and negative electrode groups not covered with gel cannot work, thereby helping the beauty instrument to exert its function, promoting the metabolism of human subcutaneous cells, and improving the skin care effect.
