Radiofrequency beauty devices use radiofrequency waves to directly penetrate the skin. When the skin forms impedance, the radiofrequency waves can cause cellular molecules to produce strong resonant rotation (on the order of millions of times per second), generating heat energy, thereby heating collagen tissue and fat cells. This causes the temperature of the underlying skin to rise instantly, stimulating the dermis and causing immediate collagen tightening and regeneration. In existing technologies, radiofrequency beauty devices typically deliver energy to the user's skin in a fixed energy distribution pattern, but this is often insufficient to meet user needs.

[0019] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] See also Figure 1 , Figure 1 Schematic diagram of the structure of a radio frequency beauty instrument in one embodiment of the present application.

[0021] like Figure 1 As shown, the radio frequency beauty instrument 1 includes a power supply 10, a controller 20, a drive circuit 30 and a first number of electrode contacts 40; the power supply 10 is connected to the drive circuit 30, the controller 20 is connected to the drive circuit 30, and the drive circuit 30 is connected to the first number of electrode contacts 40. The controller 20 divides the first number of electrode contacts 40 into a second number of electrode control groups 50 according to a preset grouping form, and controls the second number of electrode control groups 50 to be connected to the power supply 10 to output preset energy to the user, wherein the second number of electrode control groups 50 includes at least one positive electrode control group 51 and at least one negative electrode control group 52, and the second number is less than the first number.

[0022] In this embodiment, the controller 20 divides the first number of electrode contacts 40 into a second number of electrode control groups 50 according to a preset grouping form, and controls the second number of electrode control groups 50 to be connected to the power supply 10 to output preset energy to the user, thereby realizing separate control of the second number of electrode control groups 50, so that the energy size and energy distribution state output by the radio frequency beauty instrument 1 can be adjusted according to needs to meet user needs.

[0023] The electrode contacts 40 may be understood as electrode points or electrode sheets for contacting the user's skin.

[0024] In some embodiments, the preset grouping form includes multiple grouping forms, and the controller 20 is used to control the first number of electrode contacts 40 to switch from one grouping form to another grouping form.

[0025] In this embodiment, the preset grouping forms include multiple grouping forms, each of which has a different energy distribution, which can meet the diverse needs of users. The energy distribution includes the direction and flow path of the current in the skin.

[0026] See also Figures 1 to 9, Figure 1 This is a schematic structural diagram of a radio frequency beauty instrument in one embodiment of the present application; Figure 2 This is a schematic diagram of an embodiment of the present application in which electrode contacts are grouped in a ring shape; Figure 3 This is a schematic diagram of another embodiment of the present application in which electrode contacts are grouped in a ring shape; Figure 4 This is a schematic diagram of electrode contacts in a first linear grouping form in one embodiment of the present application; Figure 5 This is a schematic diagram of another embodiment of the present application in which electrode contacts are in a first linear grouping form; Figure 6 This is a schematic diagram of the electrode contacts in an embodiment of the present application in a second linear grouping form; Figure 7 This is a schematic diagram of another embodiment of the present application in which the electrode contacts are in a second linear grouping form; Figure 8 This is a schematic diagram of the electrode contacts in an embodiment of the present application in a third linear grouping form; Figure 9 A schematic diagram of another embodiment of the present application showing electrode contacts arranged in a third linear grouping, wherein gray represents electrode contacts of one polarity and black represents electrode contacts of the other polarity. For example, if gray represents a positive contact, black represents a negative contact; if gray represents a negative contact, black represents a positive contact.

[0027] like Figures 1 to 9 In some embodiments, the grouping form includes: the second number of electrode control groups 50 are arranged linearly; and at least two groups of linearly arranged electrode control groups with the same polarity are separated by at least one electrode contact with different polarity.

[0028] The linear arrangement is not an absolute linear arrangement, including a linear arrangement (such as Figures 5 to 7 ,as well as Figure 9 ), including curvilinear arrangements (such as Figure 4 and Figure 8 It is understood that the figure is only an example, and there may be many other arrangements, such as: a different total number of electrode contacts, a different number of electrode control groups, etc.

[0029] In this embodiment, at least two groups of linearly arranged electrode control groups with the same polarity are separated by at least one electrode contact with a different polarity. Under the basic requirements of energy distribution, one arrangement corresponds to one energy distribution state. The current output by each positive contact flows to each negative contact through the skin resistance. When the user switches from one grouping form to another, due to the different current directions, it can act on every position in the skin as much as possible.

[0030] In some embodiments, the linear arrangement includes a linear arrangement distributed in rows, a linear arrangement distributed in columns, and a linear arrangement distributed in diagonal lines.

[0031] Wherein, the linear arrangement distributed in rows (such as Figure 4 and Figure 5 ); linear arrangement distributed by column (as shown in Figure 6 and Figure 7 as shown); linear arrangement with cross-distribution of oblique lines (as shown Figure 8 and Figure 9 It is understood that the figure is only an example and there are many other arrangements.

[0032] The linear arrangement distributed in rows may have each row be a straight line, each row be a curve, or some rows be straight lines and some rows be curves. The linear arrangement distributed in columns and the linear arrangement distributed in oblique lines can be similarly understood.

[0033] like Figure 9 As shown, the linear arrangement with oblique cross distribution, that is, when viewed from the first direction and the second direction, each electrode contact can be linearly arranged with the electrode contacts with the same polarity in the first direction, and at the same time, can also be linearly arranged with the electrode contacts with the same polarity in the second direction, and the first direction and the second direction are in a cross relationship.

[0034] like Figures 1 to 3 As shown, in some embodiments, the grouping form includes: one of the second number of electrode control groups 50 includes an electrode contact, and the electrode contact is located at the center point, and the other electrode control groups of the second number of electrode control groups are arranged in multiple rings around the center point; at least two groups of electrode control groups with the same polarity are separated by at least one electrode contact with different polarity.

[0035] The other electrode control groups of the second number of electrode control groups 50 are arranged in a plurality of rings around the center point. The rings may be the same shape as shown in 44 for each electrode control group, or may be the same shape as shown in 45. Figure 2 Each group of circles has a different shape. From the center outward, there's a circle of four gray dots, a circle of five black dots on the left and five black dots on the right, and a circle of two gray dots on the left and two gray dots on the right. The "circle" here can be a parallelogram, polygon, circle, ellipse, or other shape.

[0036] In this embodiment, the annular arrangement includes multiple arrangement modes, each arrangement mode corresponds to an energy distribution state, and the direction of the current is also different, further improving the effect on every position inside the skin.

[0037] In some embodiments, the controller 20 controls each of the first number of electrode contacts 40 to be connected to the positive or negative pole of the power source 10 through the drive circuit 30, thereby controlling the electrode contact to be a positive contact or a negative contact.

[0038] Among them, each electrode contact is connected to the positive pole of the power supply 10 through a first circuit, and the first circuit includes a first switch; each electrode contact is connected to the negative pole of the power supply 10 through a second circuit, and the second circuit includes a second switch. When the controller 20 controls the first switch to close, the electrode contact is connected to the positive pole of the power supply 10, and the electrode contact is a positive contact; when the controller 20 controls the second switch to close, the electrode contact is connected to the negative pole of the power supply 10, and the electrode contact is a negative contact.

[0039] In this embodiment, by connecting each electrode contact to the positive pole and the negative pole of the power supply 10 respectively, the electrode contact is connected to the positive pole or the negative pole of the power supply 10 according to the needs of the grouping form. When the first number of electrode contacts 40 are switched from one grouping form to another grouping form, the switching is more flexible and can be switched to any grouping form.

[0040] In some embodiments, the grouping configuration includes: all electrode contacts in each electrode control group have the same polarity, that is, all electrode contacts in each electrode control group are either positive contacts or negative contacts.

[0041] In this embodiment, the polarity of all electrode contacts in each electrode control group is the same. The controller 20 can control the closure of the switches in the circuit connecting all electrode contacts in the electrode control group to the positive pole of the power supply through one instruction, or control the closure of the switches in the circuit connecting all electrode contacts in the electrode control group to the negative pole of the power supply. If the polarity of all electrode contacts in each electrode control group is not the same, the controller 20 requires multiple instructions for control. Therefore, this embodiment makes the control work of the controller 20 more convenient and quick.

[0042] In some embodiments, the electrode contacts include positive contacts and negative contacts, each of the positive contacts has a negative contact within a preset distance around it, and each of the negative contacts has a positive contact within a preset distance around it.

[0043] In this embodiment, each of the positive contacts has a negative contact within a preset distance range around it. This can be understood as taking the positive contact as the center, connecting the three electrode contacts in any direction, and selecting the longest connection length as the radius to draw a circle. There must be at least one negative contact within the circle; each of the negative contacts has a positive contact within a preset distance range around it, and the same applies.

[0044] In this embodiment, each of the positive contacts has the negative contact within a preset distance range around it, and each of the negative contacts has the positive contact within a preset distance range around it. When the distance between the positive contact and the negative contact is too large, the invalid energy consumption will increase. In addition to the skin resistance, there are some other resistances, and the work done on the other resistances is useless work. Therefore, in this embodiment, the invalid power consumption of the radio frequency beauty instrument 1 can be reduced.

[0045] In some embodiments, when the first number is an even number, the first number of electrode contacts 40 are centered on one point in the plane where the first number of electrode contacts 40 are located, and the electrode contacts with the same polarity are symmetrical about the center; or, when the first number is an odd number, one of the electrode contacts is located at the center, and the remaining electrode contacts with the same polarity are symmetrical about the center.

[0046] In this embodiment, the electrode contacts with the same polarity are symmetrical with respect to the center, which can improve the uniformity of energy distribution.

[0047] In some embodiments, when the first number is an even number, the electrode contacts with the same polarity are symmetrical in pairs about a straight line where the center is located; or, when the first number is an odd number, one of the electrode contacts is located at the center, and the electrode contacts with the same polarity among the remaining electrode contacts are symmetrical in pairs about a straight line where the center is located.

[0048] The straight line where the center is located includes a horizontal straight line where the center is located and a vertical straight line where the center is located.

[0049] In this embodiment, on the basis that the electrode contacts with the same polarity are symmetrical in pairs about the center, the electrode contacts with the same polarity are additionally symmetrical in pairs about a straight line where the center is located. That is, the electrode contacts with the same polarity satisfy both the central symmetry relationship and the axial symmetry relationship, further improving the uniform distribution of energy.

[0050] See also Figure 1 and Figure 10 , Figure 1 This is a schematic structural diagram of a radio frequency beauty instrument in one embodiment of the present application; Figure 10 Schematic diagram of a simplified circuit of a radio frequency beauty device in one embodiment of the present application.

[0051] In some embodiments, the current output or input of each electrode contact in each electrode control group is within the same range.

[0052] In this embodiment, the polarity of all electrode contacts in each electrode control group is the same, and the current output or input of each electrode contact in each electrode control group is within the same range, that is, when all electrode contacts in one electrode control group are positive contacts, the current output by each electrode contact in the electrode control group is within the same range; when all electrode contacts in another electrode control group are negative contacts, the current input by each electrode contact in the electrode control group is within the same range.

[0053] like Figure 1 and Figure 10 As shown, any positive contact and any negative contact form a circuit branch, for example: the first number of electrode contacts is 5 in total, of which 3 positive contacts A1, A2, and A3 are the first electrode control group, and 2 negative contacts B1 and B2 are the second electrode control group. The current output by the positive contact A1 will flow to the negative contacts B1 and B2 respectively through the skin resistance. Similarly, the current output by the positive contact A2 will flow to the negative contacts B1 and B2 respectively through the skin resistance, and the current output by the positive contact A3 will flow to the negative contacts B1 and B2 respectively through the skin resistance. Since there is a skin resistance between each positive contact and each negative contact, there are a total of six skin resistances, R1, R2, R3, R4, R5, and R6. The specific value of each skin resistance is determined by the distance between the positive contact and the negative contact, and the skin resistivity, etc. However, since the positive contact can be reasonably arranged The position relationship between the contacts and the negative contact, and the current is similar to the depth of the skin layer, so the sizes of R1, R2, R3, R4, R5, and R6 are all in the same range. Therefore, when the power supply 10 provides a voltage U, the current output by the positive contact A1 is equal to U / R1+U / R4, the current output by the positive contact A2 is equal to U / R2+U / R5, and the current output by the positive contact A3 is equal to U / R3+U / R6. 3. The values ​​of R4, R5, and R6 are all in the same range, so the currents output by the positive contacts A1, A2, and A3 are in the same range, and this range is determined by the skin resistance; similarly, the current input by the negative contact B1 is equal to U / R1+U / R2+U / R3, and the current input by the negative contact B2 is equal to U / R4+U / R5+U / R6, so the currents input by the negative contacts B1 and B2 are also in the same range, and this range is determined by the skin resistance.

[0054] In this embodiment, the current output or input of each electrode contact in each electrode control group is within the same range, which is conducive to controlling the output energy and controlling the distribution of energy to meet user needs.

[0055] In some embodiments, at least two electrode control groups with the same polarity among the second number of electrode control groups output different energies.

[0056] In this embodiment, at least two electrode control groups with the same polarity among the second number of electrode control groups output different energies. This allows the electrode contacts of the radio frequency beauty instrument 1 to be in a working state and work on the user's skin. At the same time, the radio frequency beauty instrument 1 does not need to be in a high power consumption state all the time, saving energy. While switching the electrode control group with high output energy to a low energy output group and the electrode control group with low output energy to a high energy output group, the safety performance of the radio frequency beauty instrument 1 is further enhanced to avoid being in a high energy output state all the time and causing burns.

[0057] like Figure 11 As shown, Figure 11 Schematic diagram of a flow chart of a radio frequency output control method in one embodiment of the present application.

[0058] like Figure 11 As shown, the radio frequency output control method includes the following steps:

[0059] S01: Dividing a first number of electrode contacts into a second number of electrode control groups according to a preset grouping form;

[0060] S02: Control the second number of electrode control groups and the power supply to output preset energy to the user; wherein the second number of electrode control groups includes at least one positive contact group and at least one negative contact group, and the second number is less than the first number.

[0061] In this embodiment, by dividing the first number of electrode contacts into a second number of electrode control groups according to a preset grouping form, and controlling the second number of electrode control groups to conduct with the power supply to output preset energy to the user, it is possible to achieve separate control of the second number of electrode control groups, so that the output energy size and energy distribution state can be adjusted as needed to meet user needs.

[0062] In some embodiments, the radio frequency output control method further includes: controlling the second number of electrode control groups to start in a preset order.

[0063] In this embodiment, the second number of electrode control groups are controlled to start up in a preset order, thereby controlling the energy flow of the second number of electrode contacts when they are started up.

[0064] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present application, and such modifications or substitutions should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
