Description

Technical Field

[0001] This application belongs to the field of electronic circuits, and in particular relates to an energy output circuit and an energy output device. Background Technology

[0002] As people's living standards improve, the demand for skin care is no longer limited to facial and limb skin, but also includes the care of intimate areas, especially women's intimate areas. For example, pelvic floor muscle care.

[0003] However, due to the physiological differences in the genital area among women, energy output devices designed to deliver energy to the skin of the genital area often fail to reach the pelvic floor nerves or muscles, thus failing to achieve the goals of muscle movement, improving muscle tissue structure, and increasing muscle tone through energy output. Therefore, there is an urgent need for an energy output solution with a wider range of applications. Utility Model Content

[0004] The purpose of this application is to provide an energy output circuit and an energy output device, aiming to provide an energy output solution with a wider range of applications.

[0005] A first aspect of this application provides an energy output circuit applied to an energy output device. The energy output device is configured with a first cluster of contact electrodes and a second cluster of contact electrodes spaced apart along the length of the energy output device. The energy output circuit includes:

[0006] The first selection unit includes a first selection branch connected to at least one first contact electrode in the first contact electrode cluster, and the end of the first selection branch away from the first contact electrode serves as the first connection end of the first selection unit.

[0007] The second selection unit includes a second selection branch connected to at least one second contact electrode in the second contact electrode cluster, and the end of the second selection branch away from the second contact electrode serves as the second connection end of the second selection unit.

[0008] An energy output unit is connected between the first connection terminal and the second connection terminal.

[0009] A second aspect of this application provides an energy output device for outputting energy to the pelvic floor muscles, including the energy output circuit provided in the first aspect above.

[0010] The beneficial effects of this utility model embodiment compared with the prior art are as follows: The above-described energy output circuit is applied to an energy output device. The energy output device is configured with a first contact electrode cluster and a second contact electrode cluster spaced apart along the length of the energy output device. The energy output circuit includes a first selection unit, a second selection unit, and an energy output unit. The first selection unit includes a first selection branch connected to at least one first contact electrode in the first contact electrode cluster, and the second selection unit includes a second selection branch connected to at least one second contact electrode in the second contact electrode cluster. The end of the first selection branch away from the first contact electrode serves as the first connection end of the first selection unit, and the end of the second selection branch away from the second contact electrode serves as the second connection end of the second selection unit. By connecting the energy output unit between the first connection end and the second connection end, a closed loop can be formed when the user uses the energy output device, through the contact of the first and second contact electrodes with the skin. Based on this, by controlling the on / off state of the first selection branch and / or the second selection branch, various combinations and pairings between the first and second contact electrode clusters can be achieved. Since the first and second contact electrode clusters are spaced apart along the length of the energy output device, the various combinations and pairings between the first and second contact electrode clusters correspond to the energy's effective length / depth, thus enabling the energy output device to have an adjustable energy effective length / depth. This provides an energy output solution with a wider range of applications and greater variability. Attached Figure Description

[0021] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0022] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0023] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0025] For example, as people's living standards improve, the demand for skin care is no longer limited to facial and limb skin, but also includes the care of intimate areas, especially women's intimate areas. For example, pelvic floor muscle care.

[0026] However, due to the physiological differences in the genital area among women, energy output devices designed to deliver energy to the skin of the genital area often fail to reach the pelvic floor nerves or muscles, thus failing to achieve the goals of muscle movement, improving muscle tissue structure, and increasing muscle tone through energy output. Therefore, there is an urgent need for an energy output solution with a wider range of applications.

[0027] To address the aforementioned technical problems, this application provides an energy output circuit applied to an energy output device. The energy output device is configured with a first cluster of contact electrodes and a second cluster of contact electrodes spaced apart along the length of the energy output device. The energy output circuit includes a first selection unit, a second selection unit, and an energy output unit. The first selection unit includes a first selection branch connected to at least one first contact electrode in the first cluster of contact electrodes, and the second selection unit includes a second selection branch connected to at least one second contact electrode in the second cluster of contact electrodes. The end of the first selection branch furthest from the first contact electrode serves as the first connection terminal of the first selection unit, and the end of the second selection branch furthest from the second contact electrode serves as the second connection terminal of the second selection unit. Connecting the energy output unit between the first and second connection terminals allows a closed loop to be formed when the user uses the energy output device, through contact with the skin by the first and second contact electrodes. Based on this, various combinations and pairings between the first and second clusters of contact electrodes can be achieved by controlling the on / off state of the first and / or second selection branches. Since the first and second contact electrode clusters are both spaced apart along the length of the energy output device, the various combinations and pairings between the first and second contact electrode clusters correspond to the energy's effective length / depth, thus enabling the energy output device to have an adjustable energy effective length / depth, thereby providing an energy output solution with a wider range of applications.

[0028] See Figure 1 , Figure 1 A schematic diagram of an energy output circuit according to an embodiment of this application is shown. For ease of explanation, only the parts relevant to this embodiment are shown, and are described in detail below:

[0029] exist Figure 1 In this context, the energy output circuit 100 is applied to an energy output device, which is configured with a first contact electrode cluster 110 and a second contact electrode cluster 120 spaced apart along the length of the energy output device. The energy output circuit 100 includes: a first selection unit 10, a second selection unit 20, and an energy output unit 30. Specifically:

[0030] The first selection unit 10 includes a first selection branch 11 connected to at least one first contact electrode 111 in the first contact electrode cluster 110. The end of the first selection branch 11 away from the first contact electrode 111 serves as the first connection terminal 101 of the first selection unit 10. The second selection unit 20 includes a second selection branch 21 connected to at least one second contact electrode 121 in the second contact electrode cluster 120. The end of the second selection branch 21 away from the second contact electrode 121 serves as the second connection terminal 201 of the second selection unit 20. The energy output unit 30 is connected between the first connection terminal and the second connection terminal.

[0031] In all embodiments of this application, the energy output device is configured with a first contact electrode cluster 110 and a second contact electrode cluster 120 spaced apart along the length direction of the energy output device. Here, the length direction of the energy output device refers to the overall length direction of the energy output device.

[0032] For example, the energy output device can be specifically strip-shaped, and the length direction of the energy output device can be understood as the length direction of the strip.

[0033] For example, an energy output device can specifically be a columnar body, and the length direction of the energy output device can be understood as the height direction of the columnar body.

[0034] For example, in a specific implementation, the first contact electrode cluster 110 may include a plurality of first contact electrodes 111, and the second contact electrode cluster 120 may include a plurality of second contact electrodes 121. For example... Figure 1 As shown, the first contact electrode cluster 110 and the second contact electrode cluster 120 are spaced apart along the length of the energy output device. Specifically, this means that the first contact electrode cluster 110 and the second contact electrode cluster 120 are sequentially and spaced apart along the length of the energy output device on its outer surface. In other words, when the first contact electrode cluster 110 and the second contact electrode cluster 120 are disposed on the outer surface of the energy output device, there is a certain distance between them, i.e., there is an insulating space between the first contact electrode cluster 110 and the second contact electrode cluster 120 on the outer surface of the energy output device.

[0035] Furthermore, the first contact electrode cluster 110 includes a plurality of first contact electrodes 111, which are spaced apart along the length of the energy output device on its outer surface. Similarly, the second contact electrode cluster 120 includes a plurality of second contact electrodes 121, which are spaced apart along the length of the energy output device on its outer surface. When a user uses the energy output device, the first contact electrodes 111 and the second contact electrodes 121 come into contact with the skin, and the skin can be considered a conductor connecting the first contact electrodes 111 and the second contact electrodes 121.

[0036] In this embodiment, the first selection unit 10 includes a first selection branch 11, which is correspondingly connected to at least one first contact electrode 111. Similarly, the second selection unit 20 includes a second selection branch 21, which is correspondingly connected to at least one second contact electrode 121. Here, one end of the first selection branch 11 is connected to the first contact electrode 111, and the other end, which is away from the first contact electrode 111, serves as the first connection end 101 of the first selection unit 10. One end of the second selection branch 12 is connected to the second contact electrode 121, and the other end, which is away from the second contact electrode 121, serves as the second connection end 201 of the second selection unit 20. The energy output unit 30 is connected between the first connection end 101 and the second connection end 201, and can form a closed loop with the first selection unit 10, the second selection unit 20, the first contact electrode 111 in contact with the skin, and the second contact electrode 121 in contact with the skin when the skin is in contact with the first contact electrode 111 and the second contact electrode 121.

[0037] Based on this, various combinations and pairings between the first contact electrode cluster 110 and the second contact electrode cluster 120 can be achieved by controlling the on / off state of the first selection branch 11 and / or the second selection branch 21.

[0038] For example, in a specific implementation, the first selection branch 11 and the second selection branch 21 can specifically be switch branches. When controlling the on / off state of the first selection branch 11 and / or the second selection branch 21, the user can manually trigger the switch branches to open or close. Alternatively, according to the types of on / off combinations of the first selection branch 11 and / or the second selection branch 21, a corresponding gear control button can be set, and the on / off state of the first selection branch 11 and / or the second selection branch 21 can be controlled through this gear control button. In this way, multiple combinations and pairings between the first contact electrode cluster 110 and the second contact electrode cluster 120 can be achieved. Since both the first contact electrode cluster 110 and the second contact electrode cluster 120 are spaced apart along the length direction of the energy output device, the multiple combinations and pairings between the first contact electrode cluster 110 and the second contact electrode cluster 120 correspond to the energy's effective length / depth. Based on this, when using the energy output device, users can control the energy output device by manually triggering the switch branch to turn on or off or by using the gear control button, thereby realizing the adjustment of the energy output device's energy effect length / depth, and thus meeting the differentiated needs of different users for energy effect length / depth.

[0039] exist Figure 1 In the first selection unit 10, the first contact electrode cluster 110 includes a plurality of first contact electrodes 111, and the first selection unit 10 includes a first selection branch 11 corresponding to and connected to at least one first contact electrode 111. Similarly, the second contact electrode cluster 120 includes a plurality of second contact electrodes 121, and the second selection unit 20 includes a second selection branch 21 corresponding to and connected to at least one second contact electrode 121. In specific implementations, one, two, or more first selection branches 11 can be provided in the first selection unit 10 for connecting the first contact electrodes 111. One, two, or more second selection branches 21 can be provided in the second selection unit 20 for connecting the second contact electrodes 121.

[0040] As one possible implementation, the first selection unit 10 includes a first selection branch 11, and the second selection unit 20 includes a second selection branch 21. When only one first contact electrode 111 in the first contact electrode cluster 110 is connected to the first selection branch 11, the other first contact electrodes 111 in the first contact electrode cluster 110 that are not connected to the first selection branch 11 can be directly connected to the first connection terminal 101 of the first selection unit 10. When only one second contact electrode 121 in the second contact electrode cluster 120 is connected to the second selection branch 21, the other second contact electrodes 121 in the second contact electrode cluster 120 that are not connected to the second selection branch 21 can be directly connected to the second connection terminal 201 of the second selection unit 20.

[0041] In practical implementation, to achieve various combinations and pairings between the first contact electrode cluster 110 and the second contact electrode cluster 120, and to clearly distinguish the energy application length / depth, the first contact electrode 111 closest to the center point of the energy output device is connected to the first selection branch 11, and / or the second contact electrode 121 closest to the center point of the energy output device is connected to the second selection branch 21. Thus, when both the first selection branch 11 and the second selection branch 21 are conducting, the energy application length / depth is near the center point of the energy output device. Furthermore, when the first selection branch 11 is conducting and the second selection branch 21 is disconnected, the energy application length / depth shifts towards the first contact electrode cluster 110. Similarly, when the first selection branch 11 is disconnected and the second selection branch 21 is conducting, the energy application length / depth shifts towards the second contact electrode cluster 210. This achieves adjustment of the energy application length / depth of the energy output device, thereby meeting the differentiated needs of different users for energy application length / depth.

[0042] Figure 2 This application provides a schematic diagram of the specific structure of an energy output circuit according to an embodiment. Figure 1 . Figure 3 This application provides a schematic diagram of the specific structure of an energy output circuit according to an embodiment. Figure 2 .like Figure 2 or Figure 3 As shown, in one possible implementation, the first contact electrode cluster 110 includes N first contact electrodes 111, where N is an integer and N≥2. The second contact electrode cluster 120 includes X second contact electrodes 121, where X is an integer and X≥2.

[0043] In one embodiment, the first selection unit 10 includes M first selection branches 11, which are connected to M of the N first contact electrodes 111. Here, M is an integer and M≤N.

[0044] like Figure 2 As shown, when M is less than N, at least one first contact electrode 111 is not connected to the first selection branch 11, that is, at least one first contact electrode 111 is directly connected to the first connection terminal 101 of the first selection unit 10.

[0045] As one embodiment, the second selection unit 20 includes Y second selection branches 21, which are connected to Y second contact electrodes 121 out of X second contact electrodes 121. Here, Y is an integer and Y≤X.

[0046] like Figure 2As shown, when Y is less than X, at least one second contact electrode 121 is not connected to the second selection branch 21, that is, at least one second contact electrode 121 is directly connected to the second connection terminal 201 of the second selection unit 20.

[0047] exist Figure 2 In the example shown, when all first selection branches 11 are disconnected, the first contact electrode 111x in the first contact electrode cluster 110 that is not connected to the first selection branch 11 can still remain connected to the energy output unit 30. For example... Figure 2 The leftmost first contact electrode 111x in the first contact electrode cluster 110. If skin is in contact between the first contact electrode 111x and the second contact electrode cluster 120, then the first contact electrode 111x and the second contact electrode cluster 120 can be electrically connected through the skin. Energy is then applied to the skin through both the first contact electrode 111x and the second contact electrode cluster 120. In this way, the length / depth of the energy application can be shifted towards the first contact electrode 111x, that is, towards the direction of the first contact electrode cluster 110. Similarly, when all second selection branches 21 are disconnected, the second contact electrode 121x in the second contact electrode cluster 120 that is not connected to a second selection branch 21 remains connected to the energy output unit 30. Figure 2 The rightmost second contact electrode 121x in the second contact electrode cluster 120. If skin is in contact between the second contact electrode 121x and the first contact electrode cluster 110, then electrical conduction can occur between them through the skin. Energy is then applied to the skin through both the second and first contact electrode clusters. In this way, the length / depth of the energy application can be shifted towards the second contact electrode 121x, or in the direction of the second contact electrode cluster 120. This allows for adjustment of the energy application length / depth of the energy output device, thereby meeting the differentiated needs of different users for energy application length / depth.

[0048] exist Figure 3 In the example shown, when M equals N, the first contact electrode 111 is connected to the first selection branch 11 in a one-to-one correspondence. When Y equals X, the second contact electrode 121 is connected to the second selection branch 21 in a one-to-one correspondence.

[0049] It is easy to understand that, in Figure 2 or Figure 3 In the example shown, when all first selection branches 11 and all second selection branches 21 are simultaneously conducting, and the energy is current energy, since current transfer follows the shortest path, therefore... Figure 2 or Figure 3The energy interaction is most pronounced on the closest contact electrodes, the first contact electrode 111y and the second contact electrode 121y. That is, in... Figure 2 or Figure 3 In the first contact electrode cluster 110, the rightmost first contact electrode 111y and the leftmost second contact electrode 121y in the second contact electrode cluster 120 have the most significant energy effect. Because these first contact electrodes 111y and 121y are located near the center point of the energy output device, the length / depth of the energy effect is concentrated near the center point. At this time, the first contact electrodes 111x and 121x, which are farther from the center point of the energy output device, can also output energy to the skin, but their energy effect is smaller compared to that of the first contact electrodes 111y and 121y near the center point.

[0050] exist Figure 3 In the example shown, with Figure 2 The difference in the example shown is that the energy output circuit 100 is in an open circuit state when all first selection branches 11 are disconnected or when all second selection branches 21 are disconnected.

[0051] See Figure 4 , Figure 4 A schematic diagram of an energy output circuit according to another embodiment of this application is shown. Figure 4 As shown, the energy output device is also configured with intermediate contact electrodes 130. The intermediate contact electrodes 130 are spaced apart between the first contact electrode cluster 110 and the second contact electrode cluster 120. Correspondingly, the energy output circuit 100 also includes a third selection unit 40. Specifically, the fixed end of the third selection unit 40 is connected to the intermediate contact electrodes 130, the first movable end of the third selection unit 40 is connected to the first connection end 101 of the first selection unit 10, and the second movable end of the third selection unit 40 is connected to the second connection end 201 of the second selection unit 20.

[0052] In all embodiments of this application, the energy output unit 30 may specifically include a current output unit, such as an EMS output unit or a radio frequency output unit. When the first contact electrode 111 and the second contact electrode 121 are in contact with the skin, the energy output unit 30 can output an EMS pulse or an radio frequency current through the first selection branch 11 or the second selection branch 21.

[0053] For example, the current pulse generally refers to a pulse current from 1 Hz to 1500 Hz. When either the first contact electrode 111 or the second contact electrode 121 is applied to the skin, the pulse current can specifically be two sets of pulse currents that flow in opposite directions and appear alternately.

[0054] For example, the direction of the first pulse current is from the first contact electrode 111, through the skin to the second contact electrode 121, and the direction of the second pulse current is from the second contact electrode 121, through the skin to the first contact electrode 111.

[0055] For example, the direction of the first pulse current is from the second contact electrode 121, through the skin to the first contact electrode 111, and the direction of the second pulse current is from the first contact electrode 111, through the skin to the second contact electrode 121.

[0056] In this way, any first contact electrode 111 in the first contact electrode cluster 110 can be regarded as a positive electrode, and any second contact electrode 121 in the second contact electrode cluster 120 can be regarded as a negative electrode. Alternatively, any first contact electrode 111 in the first contact electrode cluster 110 can be regarded as a negative electrode, and any second contact electrode 121 in the second contact electrode cluster 120 can be regarded as a positive electrode.

[0057] In this embodiment, since the first active end of the third selection unit 40 is connected to the first connection end 101 of the first selection unit 10, and the second active end of the third selection unit 40 is connected to the second connection end 201 of the second selection unit 20, different polarity control of the intermediate contact electrode 130 can be achieved by controlling different states of the third selection unit 40.

[0058] For example, taking the first connection terminal 101 of the first selection unit 10 as the positive terminal of the energy output unit, the polarity of the first contact electrode 111 is positive, i.e., the first contact electrode 111 is a positive electrode. The polarity of the second contact electrode 121 is negative, i.e., the second contact electrode 121 is a negative electrode. When the first active terminal of the control third selection unit 40 is connected to the fixed terminal, the polarity of the intermediate contact electrode 130 is the same as that of the first contact electrode 111, i.e., the intermediate contact electrode 130 is a positive electrode. When the intermediate contact electrode 130 is a positive electrode, and there is skin between the intermediate contact electrode 130 and the second contact electrode cluster 120, a connection can be formed between the intermediate contact electrode 130 and the second contact electrode cluster 120 through the skin. At this time, the energy application area can be from the intermediate contact electrode 130 to the second contact electrode cluster 120. That is, the energy application area can be... Figure 4 In the first length direction.

[0059] Furthermore, by controlling the on / off state of all or some of the second selection branches 21 in the second selection unit 20, the energy application area can be further adjusted. That is, by controlling the on / off state of all or some of the second selection branches 21 in the second selection unit 20, the energy application length / depth can be adjusted. Figure 4 Adjustment in the first length direction.

[0060] When the second active terminal of the control third selection unit 40 is connected to the fixed terminal, the polarity of the intermediate contact electrode 130 is the same as that of the second contact electrode 121, that is, the intermediate contact electrode 130 is a negative electrode at this time. When the intermediate contact electrode 130 is a negative electrode, and there is skin contact between the first contact electrode cluster 110 and the intermediate contact electrode 130, a connection can be formed between the first contact electrode cluster 110 and the intermediate contact electrode 130 through the skin. At this time, the energy application area can be from the first contact electrode cluster 110 to the intermediate contact electrode 130. That is, the energy application area can be... Figure 4 In the second length direction.

[0061] Furthermore, by controlling the on / off state of all or part of the first selection branches 11 in the first selection unit 10, the energy application area can be further adjusted. That is, by controlling the on / off state of all or part of the first selection branches 11 in the first selection unit 10, the energy application length / depth can be adjusted. Figure 4 Mediation in the second length direction.

[0062] When the third selection unit 40 is disconnected, the intermediate contact electrode 130 is open-circuited, and at this time, the intermediate contact electrode 130 has no polarity. The energy application area can then extend from the first contact electrode cluster 110 to the second contact electrode cluster 120. Furthermore, the energy application area can be further adjusted by controlling the on / off state of a portion of the first selection branch 11 in the first selection unit 10, and / or by controlling the on / off state of a portion of the second selection branch 21 in the second selection unit 20.

[0063] The above solution, by setting an intermediate contact electrode 130 between the first contact electrode cluster 110 and the second contact electrode cluster 120, and connecting it to the fixed end of the third selection unit 40, while simultaneously connecting the first movable end of the third selection unit 40 to the first connection end 101 of the first selection unit 10, allows the energy application area to extend from the intermediate contact electrode 130 to the second contact electrode cluster 120. That is, the energy application area can be... Figure 4 In the first length direction. Connect the second movable end of the third selection unit 40 to the second connection end 201 of the second selection unit 20, at which time the energy application area can be from the first contact electrode cluster 110 to the middle contact electrode 130. That is, at this time the energy application area can be in Figure 4In the second length direction. In this way, the polarity of the intermediate contact electrode 130 can be flexibly adjusted by controlling the third selection unit 40, so that the intermediate contact electrode 130 can be matched with different contact electrode clusters according to different polarities, thereby forming different energy action areas or energy action lengths / depths. This can realize the adjustment of the energy action range and the finer adjustment of the energy action length / depth. This not only enriches the adjustment methods of the energy action length / depth of the energy output device, but also, by making the polarity of the intermediate contact electrode 130 variable, more combination methods can be realized by combining the first contact electrode cluster 110 and the second contact electrode cluster 120, which is beneficial to improving the adjustment accuracy of the energy action length / depth.

[0064] Figure 5 This application illustrates a specific circuit diagram of an energy output circuit provided in an embodiment of the present application. Figure 1 .like Figure 5 As shown, in a specific implementation, the first selection branch 11 and the second selection branch 21 can be implemented using the same switch branch. Here, the switch branch can specifically include a single-pole single-throw switch S1.

[0065] exist Figure 5 Unlike the first selection branch 11 or the second selection branch 21, the third selection unit 40 may specifically include a single-pole double-throw switch S2. When the single-pole double-throw switch S2 is open, the intermediate contact electrode 130 has no polarity, and the energy application area can be from the first contact electrode 111x to the second contact electrode 121x. When the single-pole double-throw switch S2 is closed to the first active end, thereby connecting the intermediate contact electrode 130 to the first connection end 101 of the first selection unit 10, the polarity of the intermediate contact electrode 130 is the same as that of the first contact electrodes (111x, 111y), and the energy application area can be from the intermediate contact electrode 130 to the second contact electrode 121x. When the single-pole double-throw switch S2 closes to the second active end, thereby connecting the intermediate contact electrode 130 to the second connection end 201 of the second selection unit 20, the polarity of the intermediate contact electrode 130 is the same as that of the second contact electrode (121x, 121y). At this time, the energy application area can be from the first contact electrode 111x to the intermediate contact electrode 130.

[0066] It is readily understood that, in some embodiments, where some of the first contact electrodes 111 in the first contact electrode cluster 110 are connected to the first selection branch 11, some of the first contact electrodes 111 may not be connected to the first selection branch 11, that is, some of the first contact electrodes 111 may be directly connected to the first connection terminal 101 of the first selection unit 10. For example Figure 5 The first contact electrode in the middle is 111z.

[0067] Alternatively, if some of the second contact electrodes 121 in the second contact electrode cluster 120 are connected to the second selection branch 21, then some of the second contact electrodes 121 may not be connected to the second selection branch 21, that is, some of the second contact electrodes 121 may be directly connected to the second connection terminal 201 of the second selection unit 20. For example... Figure 5 The second contact electrode 121z.

[0068] Combination Figures 1 to 5 It is understandable that some of the first contact electrodes 111 are directly connected to the first connection terminal 101 of the first selection unit 10, and / or some of the second contact electrodes 121 are directly connected to the second connection terminal 201 of the second selection unit 20. This only involves the specific implementation of the first contact electrode cluster 110 and the first selection unit 10, and the specific implementation of the second contact electrode cluster 120 and the second selection unit 20. It will not affect the function of using the single-pole double-throw switch S2 to enable the intermediate contact electrode 130 to switch between different states.

[0069] Figure 6 This application illustrates a specific circuit diagram of an energy output circuit provided in an embodiment of the present application. Figure 2 .like Figure 6 As shown, in one embodiment, the first contact electrode 111 includes a first electrode 111a and a second electrode 111b. The first node P1 formed by connecting the first electrode 111a and the second electrode 111b is used to connect the first selection branch 11.

[0070] like Figure 6 As shown, in one embodiment, the second contact electrode 121 includes a third electrode 121a and a fourth electrode 121b. The second node P2 formed by connecting the third electrode 121a and the fourth electrode 121b is used to connect the second selection branch 21.

[0071] In this embodiment, to maximize the overlap between the energy application coverage and the length range of the energy output device, the contact electrode cluster can be subdivided, specifically the first contact electrode 111 and / or the second contact electrode 121. Therefore, in practical implementation, the first contact electrode 111 or the second contact electrode 121 can be considered a single contact electrode, or the first electrode 111a and / or the second electrode 111b can be considered a single contact electrode, or the third electrode 121a and / or the fourth electrode 121b can be considered a single contact electrode; no limitation is imposed here.

[0072] In a practical implementation, the first electrode 111a and the second electrode 111b can be contact electrodes with the same structure and size. Similarly, the third electrode 121a and the fourth electrode 121b can also be contact electrodes with the same structure and size.

[0073] It is readily understood that, in implementation, if the first electrode 111a or the second electrode 111b is considered a single contact electrode, then the first electrode 111a and the second electrode 111b can be regarded as two first contact electrodes 111, that is, the first electrode 111a and the second electrode 111b form the first contact electrode cluster 110 in this embodiment. Similarly, if the third electrode 121a or the fourth electrode 121b is considered a single contact electrode, then the third electrode 121a and the fourth electrode 121b can be regarded as two second contact electrodes 121, that is, the third electrode 121a and the fourth electrode 121b form the second contact electrode cluster 120 in this embodiment.

[0074] Based on this, as one possible implementation, the first contact electrode cluster 110 includes a first electrode 111a and a second electrode 111b, and a first node P1 formed by connecting the first electrode 111a and the second electrode 111b is used to connect the first selection branch 11. The second contact electrode cluster 120 includes a third electrode 121a and a fourth electrode 121b, and a second node P2 formed by connecting the third electrode 121a and the fourth electrode 121b is used to connect the second selection branch 21.

[0075] It is understandable that, such as Figure 6 As shown, in actual implementation, the first contact electrode 111 in the energy output device can be implemented as a single contact electrode or as two contact electrodes. For example, the first contact electrode 111 may be a single contact electrode, or it may include a first electrode 111a and a second electrode 111b; this is not limited here. Similarly, the second contact electrode 121 in the energy output device can be implemented as a single contact electrode or as two contact electrodes. For example, the second contact electrode 121 may be a single contact electrode, or it may include a third electrode 121a and a fourth electrode 121b; this is not limited here.

[0076] Figure 7 This illustration shows a schematic diagram of the specific structure of an energy output unit in an energy output circuit according to an embodiment of this application. For example... Figure 7 As shown, the energy output unit 30 includes a control unit 31 and an energy generation unit 32.

[0077] Control unit 31 is connected to first selection unit 10 and second selection unit 20, respectively. Control unit 31 provides PWM signal pairs and outputs a first strobe signal to first selection unit 10 and a second strobe signal to second selection unit 20. Energy generation unit 32 is connected to control unit 31. Energy generation unit 32 outputs energy according to the PWM signal pairs.

[0078] In this embodiment, the first strobe signal is used to indicate the on / off state of the first selection branch in the first selection unit 10. The second strobe signal is used to indicate the on / off state of the second selection branch in the second selection unit 20. That is, the first selection unit 10 can respond to the first strobe signal to turn on all or part of the first selection branch, or turn off all or part of the first selection branch. Similarly, the second selection unit 20 can respond to the second strobe signal to turn on all or part of the second selection branch, or turn off all or part of the second selection branch.

[0079] It should be noted that the PWM signal is used to drive the energy generation unit 32 to output the corresponding energy. In a specific implementation, the energy generation unit 32 may include a current output unit, such as an EMS output unit or an RF output unit.

[0080] As one embodiment, the energy output circuit 100 further includes a heating unit (not shown in the figure). In this embodiment, the heating unit is connected to the control unit 31. The heating unit is used to output heat to the first contact electrode cluster 110 and / or the second contact electrode cluster 120 according to the heating control signal sent by the control unit 31. Accordingly, the control unit 31 is also used to send a heating control signal to the heating unit.

[0081] It is understandable that when the energy output device is used on a user's private parts, if the outer surface temperature of the energy output device is low, it may affect the user experience. Therefore, by setting up a heating unit, the user can choose to heat the first contact electrode cluster 110 and / or the second contact electrode cluster 120, thereby avoiding the impact on the user experience due to the low outer surface temperature of the energy output device.

[0082] In a specific implementation, the heating unit can be at least one of an LED light-emitting circuit and a PTC heating circuit.

[0083] As an example, taking a heating unit that includes an LED light-emitting circuit, the control unit 31 sends a heating control signal to the LED light-emitting circuit, thereby controlling the LED light-emitting circuit to emit light, heating the air around the LED beads through light energy, and then transferring heat energy to the first contact electrode cluster 110 and / or the second contact electrode cluster 120.

[0084] As another example, taking a heating unit that includes a PTC heating circuit, the control unit 31 sends a heating control signal to the PTC heating circuit, thereby controlling the PTC heating circuit to operate. The PTC heating circuit can be located near the first contact electrode cluster 110 and / or the second contact electrode cluster 120. During operation, the PTC heating circuit converts electrical energy into heat energy, thereby heating the air around the PTC heating circuit, and then transferring the heat energy to the first contact electrode cluster 110 and / or the second contact electrode cluster 120.

[0085] Referring to the above example, taking a heating unit comprising an LED light-emitting circuit and a PTC heating circuit as an example, the control unit 31 sends a heating control signal to the heating unit, thereby controlling the LED light-emitting circuit and the PTC heating circuit to operate simultaneously. At this time, the LED light-emitting circuit emits light, heating the air around the LED beads through light energy, and then transferring heat energy to the first contact electrode cluster 110 and / or the second contact electrode cluster 120. Simultaneously, during operation, the PTC heating circuit converts electrical energy into heat energy, heating the air around the PTC heating circuit, and then transferring heat energy to the first contact electrode cluster 110 and / or the second contact electrode cluster 120. Here, because the LED light-emitting circuit and the PTC heating circuit simultaneously output heat to the first contact electrode cluster 110 and / or the second contact electrode cluster 120, the heating efficiency is high. Furthermore, since the LED light-emitting circuit emits light, it can be observed by the user; therefore, when the LED light-emitting circuit is working and emitting light, it can serve as a reminder to the user that the heating function has been triggered.

[0086] Figure 8 A schematic diagram illustrating the specific structure of an energy generation unit in an energy output circuit according to an embodiment of this application is shown. For example... Figure 8 As shown in the illustration, in one embodiment, the energy generation unit 32 is configured with a loop node 321, a first output node Vout1, and a second output node Vout2. The loop node 321 is used for coupling to ground. The first output node Vout1 is used to connect to the first selection unit 10. The second output node Vout2 is used to connect to the second selection unit 20.

[0087] In this embodiment, the PWM signal pair includes a first PWM signal and a second PWM signal. Accordingly, the energy generation unit 32 includes a first bridge branch 3201 and a second bridge branch 3202. Here, the first bridge branch 3201 and the second bridge branch 3202 form an H-bridge circuit.

[0088] like Figure 8 As shown in the illustration, in one embodiment, the first bridge branch 3201 is configured with a first voltage terminal V1, a first controlled terminal D1, a second controlled terminal D2, and a first loop terminal G1. The second bridge branch 3202 is configured with a second voltage terminal V2, a third controlled terminal D3, a fourth controlled terminal D4, and a second loop terminal G2. The first voltage terminal V1 and the second voltage terminal V2 are connected to form a power supply node Vin, used for inputting operating power. The first controlled terminal D1 and the fourth controlled terminal D4 are both used to input a first PWM signal, and the second controlled terminal D2 and the third controlled terminal D3 are both used to input a second PWM signal. The first loop terminal G1 and the second loop terminal G2 are connected to a common loop node 321.

[0089] In this embodiment, a PWM signal pair refers to two sets of PWM signals with complementary frequencies within a unit cycle. In specific implementation, the PWM signal pair can be a signal pair generated by the control unit 31, or a signal pair output by the control unit 31 through its internally integrated drive unit or drive circuit; no limitation is imposed here.

[0090] In a specific implementation, the PWM signal pair may include a first PWM signal and a second PWM signal, and the frequencies of the first PWM signal and the second PWM signal are complementary within a unit cycle. Here, frequency complementarity means that at any given moment, only one of the first PWM signal and the second PWM signal is at a high level. For example, when the first PWM signal is at a high level, the second PWM signal is at a low level, and when the second PWM signal is at a high level, the first PWM signal is at a low level. This alternation can output alternating current pulses through the first output node Vout1 and the second output node Vout2, thereby acting on the skin through the first selection unit 10, the first contact electrode cluster 110, the second selection unit 20, and the second contact electrode cluster 120.

[0091] In this embodiment, the first bridge branch 3201 and the second bridge branch 3202 form an H-bridge circuit. That is, in a specific implementation, the first bridge branch 3201 and the second bridge branch 3202 can be circuits with the same structure and symmetrical about the central axis extending from the power supply node Vin.

[0092] In practical implementation, both the first bridge branch 3201 and the second bridge branch 3202 can be switching circuits composed of electronic switches or switching transistors. The PWM signal pair includes a first PWM signal and a second PWM signal, and the first PWM signal and the second PWM signal are a staggered signal pair or a frequency complementary signal pair. That is, at any given moment within a unit cycle, when the first PWM signal is high, the second PWM signal is low, and when the first PWM signal is low, the second PWM signal is high. In other words, at a certain moment, the first PWM signal and the second PWM signal are both opposite level signals.

[0093] Based on this, taking the first PWM signal and the second PWM signal as complementary signal pairs within a unit cycle as an example, the first PWM signal can be at a high level at the first moment within the unit cycle, and the second PWM signal can be at a high level at the second moment within the unit cycle. For example, when both the first controlled terminal D1 of the first bridge branch 3201 and the fourth controlled terminal D4 of the second bridge branch 3202 are used to input the first PWM signal, it can be determined that the controlled frequencies of the first controlled terminal D1 and the fourth controlled terminal D4 are the same. Therefore, under the action of the first PWM signal, at the first moment within a unit cycle, the first bridge branch 3201 can output energy through the first output node Vout1, and this energy, after being applied to the skin through the first selection unit 10 and the first contact electrode cluster 110, is then transmitted to the second selection unit 20 through the second contact electrode cluster 120, and then to the loop node 321 through the second output node Vout2.

[0094] Similarly, since the second controlled terminal D2 of the first bridge branch 3201 and the third controlled terminal D3 of the second bridge branch 3202 are both used to input the second PWM signal, that is, the controlled frequencies of the second controlled terminal D2 and the third controlled terminal D3 are the same, under the action of the second PWM signal, the second bridge branch 3202 can output energy through the second output node Vout2, and this energy is applied to the skin through the second selection unit 20 and the second contact electrode cluster 120, and then transmitted to the first selection unit 10 through the first contact electrode cluster 110, and then transmitted to the loop node 321 through the first output node Vout1.

[0095] Figure 9 It shows Figure 8 The circuit diagram of the medium-energy generation unit as the EMS output unit is shown below. Figure 8 and Figure 9 As an example, the first bridge branch 3201 includes: a first resistor R1, a second resistor R2, a third resistor R3, a first switch Q1, and a second switch Q2.

[0096] Combination Figure 8 and Figure 9 The first end of the first resistor R1 serves as the first controlled terminal D1. The second end of the first resistor R1 and the first end of the second resistor R2 are connected together to the controlled terminal of the first switch Q1. The low potential terminal of the first switch Q1 is connected to the second end of the second resistor R2, forming a node that serves as the first voltage terminal V1. The high potential terminal of the first switch Q1 serves as the first output node Vout1. The high potential terminal of the second switch Q2 is connected to the high potential terminal of the first switch Q1. The low potential terminal of the second switch Q2 serves as the first loop terminal G1. The controlled terminal of the second switch Q2 is connected to the first end of the third resistor R3. The second end of the third resistor R3 serves as the second controlled terminal D2.

[0097] exist Figure 9 In the circuit, the second bridge branch 3202 includes: a fourth resistor R4, a fifth resistor R5, a sixth resistor R6, a third switch Q3, and a fourth switch Q4. The first terminal of the fourth resistor R4 serves as the third controlled terminal D3. The second terminal of the fourth resistor R4 and the first terminal of the fifth resistor R5 are connected to the controlled terminal of the third switch Q3. The low-potential terminal of the third switch Q3 is connected to the second terminal of the fifth resistor R5, forming a node that serves as the second voltage terminal V2. The high-potential terminal of the third switch Q3 serves as the second output node Vout2. The high-potential terminal of the fourth switch Q4 is connected to the high-potential terminal of the third switch Q3. The low-potential terminal of the fourth switch Q4 serves as the second loop terminal G2. The controlled terminal of the fourth switch Q4 is connected to the first terminal of the sixth resistor R6. The second terminal of the sixth resistor R6 serves as the fourth controlled terminal D4.

[0098] For example, the PWM signal pair includes a first PWM signal and a second PWM signal, and the first PWM signal and the second PWM signal are a staggered signal pair or a frequency complementary signal pair. Taking the first PWM signal being high during a first time period within a unit period and low during a second time period within a unit period, and the second PWM signal being low during the first time period within a unit period and high during the second time period within a unit period as an example. Combined with... Figures 1 to 8 ,exist Figure 9 In the circuit shown, the first switch Q1 is turned on during the first time period and turned off during the second time period under the action of the first PWM signal. When the first switch Q1 is turned on, if the first contact electrode cluster 110 and the second contact electrode cluster 120 are in contact with the skin, the EMS pulse can be transmitted through the first selection unit 10 to the first contact electrode cluster 110 to act on the skin, and then transmitted to the loop node 321 via the second contact electrode cluster 120, the second selection unit 20 and the fourth switch Q4.

[0099] Similarly, under the action of the second PWM signal, the third switch Q3 is turned off during the first time period and turned on during the second time period. When the third switch Q3 is turned on, if the first contact electrode cluster 110 and the second contact electrode cluster 120 are in contact with the skin, the EMS pulse can be transmitted through the second selection unit 20 to the second contact electrode cluster 120 to act on the skin, and then transmitted to the loop node 321 via the first contact electrode cluster 110, the first selection unit 10 and the second switch Q2.
