Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is a schematic structural diagram of a massage apparatus provided by the present invention, and as shown in fig. 1, the massage apparatus includes a control module 110, a signal generation module 120 connected to the control module 110, and at least one electrode assembly 130 connected to the signal generation module 120;

the electrode assembly 130 comprises at least two independent electrodes 131 and a common electrode 132, wherein the at least two independent electrodes 131 are arranged at intervals, the independent electrodes 131 are arranged at intervals with the common electrode 132, and the independent electrodes 131 and the common electrode 132 are used for acting on the human body; the at least two individual electrodes 131 share the common electrode 132;

the control module 110 is configured to control the signal generating module 120 to generate a massage signal flowing from at least one of the at least two independent electrodes 131 to the common electrode 132 or from the common electrode 132 to at least one of the at least two independent electrodes 131.

Specifically, the massage device is provided with a control module 110, a signal generation module 120 and an electrode assembly 130 which are connected in sequence, wherein the control module 110 is used for controlling the signal generation module 120 to generate and output massage signals, and electrodes in the electrode assembly 130 are used for generating current acting on a human body under the action of the massage signals output by the signal generation module 120, so that the effect of massaging the human body is achieved.

Considering that the massage effect of the electrodes appearing in pairs is monotonous in the conventional EMS massage scheme and cannot truly simulate to replace manual massage, the embodiment of the present invention proposes the electrode assembly 130 including the independent electrodes 131 and the common electrodes, thereby changing the conventional massage manner.

The electrode assembly 130 provided by the embodiment of the present invention includes at least two independent electrodes 131 and a common electrode 132, each independent electrode 131 and a unique common electrode 132 in the electrode assembly 130 may form a set of electrode pairs, that is, at least two sets of electrode pairs exist in the electrode assembly 130, and the same common electrode 132 is shared by the sets of electrode pairs existing in the electrode assembly 130. The individual electrodes 131 and the common electrodes 132 are different in that each individual electrode 131 corresponds to a unique set of electrode pairs, and the common electrodes 132 correspond to at least two sets of electrode pairs. It is to be understood that the individual electrodes 131 and the common electrodes 132 are not different in structural arrangement of the electrodes themselves, and the circles filled with the blanks and the circles filled with the stripes in fig. 1 are only for convenience of understanding and are not limited to the shapes and surface patterns of the electrodes in practical use.

Under the control of the control module 110, the signal generating module 120 may generate and transmit a massage signal to at least one of the independent electrodes 131, so that the massage signal output by the at least one of the independent electrodes 131 can flow into the common electrode 132 through the human body to form a loop, or the signal generating module 120 may also generate and transmit a massage signal to the common electrode 132, so that the massage signal output by the common electrode 132 can flow into the at least one of the independent electrodes 131 through the human body to form a loop.

Further, in the case that the signal generating module 120 generates and transmits the massage signal to at least one of the independent electrodes 131 in the independent electrodes 131, so that the massage signal output by the at least one of the independent electrodes 131 can flow into the common electrode 132 through the human body to form a loop, the intensity of the massage signal transmitted to each of the independent electrodes 131 by the signal generating module 120 is adjustable, and the intensity of the massage signal transmitted to each of the independent electrodes 131 may be the same or different. Because the massage signals of the individual electrodes 131 all flow to the same common electrode 132, the massage signal vectors flowing from the individual electrodes 131 to the common electrode 132 can be combined, and it can be understood that the direction of the combined massage signal vector can be changed by changing the voltage of the massage signal transmitted by the individual electrodes 131 under the condition that the arrangement positions of the individual electrodes 131 and the common electrode 132 are not changed, and the direction of the combined massage signal vector can be flexibly changed, thereby breaking through the scheme of massaging only on the connection line between the two electrodes in the related art and realizing the massage scheme on the plane dimension.

In the case that the signal generating module 120 generates and transmits the massage signal to the common electrode 132 so that the massage signal output by the common electrode 132 can flow into at least one of the independent electrodes 131 through the human body to form a loop, the signal generating module 120 may adjust each of the independent electrodes 131 to be grounded or isolated, thereby making the intensity of the massage signal output by the common electrode 132 transmitted to each of the independent electrodes 131 adjustable, and the intensity of the massage signal transmitted to each of the independent electrodes 131 may be the same or different. Since the massage signals of the same common electrode 132 flow to the individual electrodes 131, the massage signal vectors flowing from the common electrode 132 to the individual electrodes 131 can be combined, and it can be understood that, under the condition that the positions of the individual electrodes 131 and the common electrode 132 are not changed, the voltage of the massage signals flowing to the individual electrodes 131 is changed, that is, the direction of the combined massage signal vector can be changed, the direction of the combined massage signal vector is flexible and variable, and the scheme of massaging only on the connection line between the two electrodes in the related art is broken through, thereby realizing the massage scheme in the plane dimension.

According to the massage device provided by the embodiment of the invention, at least two independent electrodes and one common electrode are arranged in the electrode assembly, so that at least one path of massage signals flowing to or flowing out of the common electrode can be generated in the massage process, and the combined direction-adjustable massage signals can be formed by combining vectors of at least one path of massage signals, so that the scheme of massaging only on a connecting line between the two electrodes in the related art is broken through, the massage scheme on the surface dimension is realized, the massage device is more suitable for the massage manipulation of a human hand, and the massage experience is improved. In addition, the massage equipment can realize multi-point massage only by being provided with a small number of electrodes, and the manufacturing cost of the massage equipment is effectively controlled while massage manipulations are enriched.

In addition, the massage equipment provided by the embodiment of the invention can electrically stimulate any point in the area covered by the electrode, so that the massage manipulation is changed from a line to a surface for massage, and the body feeling and the strength of the massage are greatly enriched.

Based on the above embodiment, the common electrode 132 is disposed outside the connection line between each two independent electrodes 131 of the at least two independent electrodes 131.

Specifically, for any two of the individual electrodes 131 in the electrode assembly 130, if the common electrode 132 is disposed on the connection line between the two individual electrodes 131, the two massage signals are combined without affecting the direction of the combined massage signal vector regardless of the variation in the intensity of the massage signal transmitted between the two individual electrodes 131 and the common electrode 132. Therefore, in order to ensure that the direction of the massage signal vector is variable, thereby realizing a massage scheme in the plane dimension, when setting for each electrode in the electrode assembly, it is necessary to ensure that the common electrode 132 is always set out of the connection line between every two independent electrodes 131.

For example, fig. 2 is a schematic diagram of an arrangement of the electrode assembly provided by the present invention, as shown in fig. 2, the common electrode 132 is arranged outside a connecting line between the two independent electrodes 131, solid arrows in fig. 2 represent massage signals transmitted between the two independent electrodes 131 and the common electrode 132, respectively, and dashed arrows represent massage signal vectors obtained by combining the two massage signals, it can be understood that, as the intensity of the massage signals transmitted between the two independent electrodes 131 and the common electrode 132 changes, the direction of the combined massage signal vector also changes, and the direction range of the combined massage vector is within a triangular region formed by the vertices of the two independent electrodes 131 and the common electrode 132.

Based on any of the above embodiments, when the number of the independent electrodes 131 is greater than or equal to 3, the common electrode 132 is disposed in the enclosed region of at least three independent electrodes 131, or the common electrode 132 is disposed outside the enclosed region of at least three independent electrodes 131.

Specifically, in the case that the number of the independent electrodes 131 included in the electrode assembly 130 is greater than or equal to 3, all the independent electrodes 131 included in the electrode assembly 130 may form a surrounding area, for example, in the case that the number of the independent electrodes 131 is 3, the surrounding area formed by the independent electrodes 131 may be a triangular area, in the case that the number of the independent electrodes 131 is 4, the surrounding area formed by the independent electrodes 131 may be a quadrangular area, and the surrounding area may be a square, a rectangle, a rhombus, or the like, according to the arrangement position of the independent electrodes 131, which is not particularly limited in the embodiment of the present invention.

For the enclosed region formed by the independent electrodes 131, the common electrode 132 may be disposed in the enclosed region, for example, fig. 3 is a second schematic view of the electrode assembly provided in the present invention, as shown in fig. 3, the common electrode 132 is disposed in the quadrilateral enclosed region formed by the four independent electrodes 131, and by adjusting the intensity of the massage signal transmitted between each of the four independent electrodes 131 and the common electrode 132, the massage experience of the circular or elliptical region centered on the common electrode 132 may be achieved.

For the enclosed region formed by the independent electrodes 131, the common electrode 132 may be disposed outside the enclosed region, for example, fig. 4 is a third schematic view of the electrode assembly provided in the present invention, as shown in fig. 4, the common electrode 132 is disposed outside the quadrilateral enclosed region formed by the four independent electrodes 131, and by adjusting the intensity of the massage signal transmitted between each of the four independent electrodes 131 and the common electrode 132, the massage experience of the sector region centered on the common electrode 132 may be achieved.

Based on any of the above embodiments, fig. 5 is four schematic views illustrating the arrangement of the electrode assembly provided by the present invention, as shown in fig. 5, in the case that the number of the independent electrodes 131 is 3, the enclosed area is triangular, and the common electrode 132 is arranged in the enclosed area.

Specifically, fig. 5 shows a case where a triangular enclosure region is constituted with three individual electrodes 131 as three vertices, and the common electrode 132 is disposed within the triangle. In the arrangement of the electrode assembly shown in fig. 5, the intensity of the massage signal transmitted between any two independent electrodes 131 of the three independent electrodes 131 and the common electrode 132 is adjusted, so that the massage experience of the sector areas formed by the two independent electrodes 131 and the common electrode 132 can be realized, and the three independent electrodes 131 are combined in pairs, so that the three groups of sector areas can just cover the circle center or the elliptical area with the common electrode 132 as the circle center, thereby realizing the regional massage of a larger area under the condition that the number of the required independent electrodes 131 is small.

Based on any of the above embodiments, the signal generating module 120 includes a power supply unit and a pulse modulation unit, the pulse modulation unit is respectively connected to the power supply unit, the control unit 110, and the at least one electrode assembly 130, the pulse modulation unit has a forward conducting state that at least one of the at least two independent electrodes 131 is conducted to the ground and the common electrode 132 is conducted to the power supply unit, and/or the pulse modulation unit has a reverse conducting state that at least one of the at least two independent electrodes 131 is conducted to the power supply unit and the common electrode 132 is conducted to the ground.

Specifically, in the signal generating module 120, the power supply unit provides electric energy for generating the massage signal, and the power supply unit may be a dc power supply or an ac power supply. The Pulse modulation unit can control the on/off between each independent electrode 131 and the common electrode 132 in the electrode assembly 130 and the power supply unit and/or between each independent electrode 131 and the common electrode 132 in the electrode assembly 130 and the ground by controlling the on/off of the switch under the action of PWM (Pulse width modulation) output by the control module 110, thereby realizing the switching of the forward conduction state and/or the reverse conduction state, and controlling the intensity of the massage signal generated by the electrode discharge and the discharge.

Further, in the forward conducting state, the pulse modulation unit may control conduction between the power supply unit and the common electrode 132, and control at least one of the individual electrodes 131 to be conducted to the ground, that is, the power supply unit provides the common electrode 132 with electric energy for generating the massage signal, and the at least one individual electrode 131 is in the ground state, at this time, the common electrode 132 may transmit the massage signal to the individual electrode 131 in the ground state through the human body.

In the reverse conducting state, the pulse modulation unit may control at least one of the individual electrodes 131 to conduct with the power supply unit, and control the common electrode 132 to conduct to the ground, that is, the power supply unit provides the at least one of the individual electrodes 131 with the electric energy for generating the massage signal, and at this time, the at least one of the individual electrodes 131 may transmit the massage signal to the common electrode 132 through the human body.

Based on any of the above embodiments, fig. 6 is a second schematic structural diagram of the massage apparatus provided by the present invention, as shown in fig. 6, the pulse modulation unit 122 includes a plurality of first pulse modulation switches S1, and the first pulse modulation switches S1 correspond to the independent electrodes 131 one to one; one end of the first pulse modulation switch S1 is connected to the output end of the power supply unit 121, and the other end of the first pulse modulation switch S1 is connected to the corresponding independent electrode 131; the control terminal of the first pulse modulation switch S1 is connected to the control module 110.

Specifically, the pulse modulation unit 122 may include a first pulse modulation switch S1 for switching the connection between the power supply unit 120 and each of the individual electrodes 131. Here, the first pulse modulation switch S1 is specifically a three-terminal structure, that is, the first pulse modulation switch S1 includes a control terminal and two connection terminals for realizing on/off of a line, where the control terminal of the first pulse modulation switch S1 is connected to the control module 110, and the control module 110 may output control information, that is, a PWM signal, for the first pulse modulation switch S1, so as to control the first pulse modulation switch S1 to be turned on or off. Two connection ends of the first pulse modulation switch S1 are respectively connected with the power supply unit 121 and the independent electrode 131, so that when the control module 110 controls the first pulse modulation switch S1 to be turned on, the power supply unit 121 is connected with the independent electrode 131 to be turned on, and when the control module 110 controls the first pulse modulation switch S1 to be turned off, the power supply unit 121 is disconnected with the independent electrode 131.

In the structure shown in fig. 6, each independent electrode 131 is correspondingly connected with one first pulse modulation switch S1, and the first pulse modulation switches S1 and the independent electrodes 131 are arranged in a one-to-one correspondence manner, so that the connection between each independent electrode 131 and the power supply unit 121 can be controlled individually. Also, for any one of the first pulse modulation switches S1, if the common electrode 132 is grounded and turned on when the first pulse modulation switch S1 is turned on, the individual electrode 131 connected to the first pulse modulation switch S1 may transmit a massage signal generated based on the electric power supplied from the power supply unit 121 to the common electrode 132 through the human body to realize a reverse conduction state. Moreover, for different individual electrodes 131, because the on and off modes of the first pulse modulation switches S1 connected to each individual electrode 131 are different, the intensity of the massage signal flowing from each individual electrode 131 to the common electrode 132 may also be different, and thus the direction of the combined massage signal vector can be flexibly changed.

In the structure shown in fig. 6, the common electrode 132 is grounded according to any of the above embodiments.

Specifically, in the structure shown in fig. 6, the common electrode 132 may be directly grounded, that is, the common electrode 132 is always grounded, and the control module 110 only needs to control the connection between each independent electrode 131 and the power supply unit 121 through the first pulse modulation switch S1 connected to each independent electrode 131, so that at least one of the independent electrodes 131 can output the massage signal flowing to the common electrode 132 under the energy provided by the power supply unit 121.

It will be appreciated that the arrangement shown in figure 6 is only used to implement a massage scheme in the reverse conducting state.

Based on any of the above embodiments, fig. 7 is a third schematic structural diagram of the massage apparatus provided by the present invention, as shown in fig. 7, the pulse modulation unit 122 further includes a plurality of second pulse modulation switches S2, and the second pulse modulation switches S2 correspond to the independent electrodes 131 one to one; one end of the second pulse modulation switch S2 is grounded, and the other end of the second pulse modulation switch S2 is connected to the corresponding independent electrode 131; the control end of the second pulse modulation switch S2 is connected to the control module 110; the control module 110 controls one of the first pulse modulation switch S1 and the second pulse modulation switch S1 to be turned on.

Specifically, the pulse modulation unit 122 may further include a second pulse modulation switch S2 for switching the connection between each independent electrode 131 and the ground. Here, the second pulse modulation switch S2 is specifically a three-terminal structure, that is, the second pulse modulation switch S2 has a control terminal and two connection terminals for realizing on/off of a line, where the control terminal of the second pulse modulation switch S2 is connected to the control module 110, and the control module 110 can output control information, that is, a PWM signal, for the second pulse modulation switch S2, so as to control the second pulse modulation switch S2 to be turned on or off. Two connection ends of the second pulse modulation switch S2 are respectively connected to the independent electrode 131 and the ground GND, so that when the control module 110 controls the second pulse modulation switch S2 to be turned on, the independent electrode 131 is turned on to the ground, and when the control module 110 controls the second pulse modulation switch S1 to be turned off, the independent electrode 131 is turned off from the ground.

In the structure shown in fig. 7, each independent electrode 131 is correspondingly connected with one second pulse modulation switch S2, and the second pulse modulation switches S2 and the independent electrodes 131 are arranged in a one-to-one correspondence manner, so that the connection between each independent electrode 131 and the ground can be controlled individually. Also, for any one of the second pulse modulation switches S2, if the common electrode 132 is turned on with the power supply unit 121 while the second pulse modulation switch S2 is turned on, the individual electrode 131 connected to the second pulse modulation switch S2 may receive a massage signal generated by the common electrode 132 based on the power supplied by the power supply unit 121 to achieve the forward conduction state.

In the configuration shown in fig. 7, one first pulse modulation switch S1 and one second pulse modulation switch S2 are connected to each individual electrode 131. In order to ensure the validity of the state switching, for a single independent electrode 131, the first pulse modulation switch S1 and the second pulse modulation switch S2 corresponding to the independent electrode 131 can be turned on only alternatively, that is, the second pulse modulation switch S2 is necessarily turned off when the first pulse modulation switch S1 is turned on, and the first pulse modulation switch S1 is necessarily turned off when the second pulse modulation switch S2 is turned on.

In addition, for a single independent electrode 131, the first pulse modulation switch S1 and the second pulse modulation switch S2 corresponding to the independent electrode 131 may be in an off state at the same time, and at this time, the independent electrode 131 is in an isolated state and does not participate in the transmission of the massage signal between the electrodes.

Based on any of the above embodiments, as shown in fig. 7, the pulse modulation unit 122 further includes a third pulse modulation switch S3 and a fourth pulse modulation switch S4;

one end of the third pulse modulation switch S3 is connected to the output end of the power supply unit 121, and the other end of the third pulse modulation switch S3 is connected to the common electrode 132; the control end of the third pulse modulation switch S3 is connected to the control module 110;

one end of the fourth pulse modulation switch S4 is grounded, and the other end of the fourth pulse modulation switch S4 is connected to the common electrode 132; the control end of the fourth pulse modulation switch S4 is connected to the control module 110; the control module 110 controls one of the third pulse modulation switch S3 and the fourth pulse modulation switch S4 to be turned on, and the control module 110 controls one of the first pulse modulation switch S1 and the third pulse modulation switch S3 to be turned on.

Specifically, the pulse modulation unit 122 may further include a third pulse modulation switch S3 for switching the connection between the common electrode 132 and the power supply unit 121, and a fourth pulse modulation switch S4 for switching the connection between the common electrode 132 and the ground. It is understood that the pulse modulation unit 122 only includes one third pulse modulation switch S3 and only includes one fourth pulse modulation switch S4. In addition, in order to ensure the validity of the state switching, the third pulse modulation switch S3 and the fourth pulse modulation switch S4 can only be turned on alternatively, that is, the fourth pulse modulation switch S4 is necessarily turned off when the third pulse modulation switch S3 is turned on, and the third pulse modulation switch S3 is necessarily turned off when the fourth pulse modulation switch S4 is turned on.

Besides, the third pulse modulation switch S3 and the fourth pulse modulation switch S4 need to be turned on and off in coordination with the turning on and off of the first pulse modulation switch S1 and the second pulse modulation switch S2. It can be understood that, in the case that the first pulse modulation switch S1 is turned on, the individual electrode 131 corresponding to the first pulse modulation switch S1 is communicated with the power supply unit 121, in order to ensure that the massage signal flowing out from the individual electrode 131 can flow to the common electrode 132, the third pulse modulation switch S3 is turned off to ensure that the connection between the common electrode 132 and the power supply unit 121 is disconnected, and the fourth pulse modulation switch S4 is turned on to ensure that the common electrode 132 is grounded.

In order to ensure that the massage signal flowing out of the common electrode 132 can flow to the individual electrode 131, the first pulse modulation switch S1 is turned off to ensure that the connection between the individual electrode 131 and the power supply unit 121 is disconnected, and the second pulse modulation switch S2 is turned on to ensure that the individual electrode 131 is grounded.

Based on any of the above embodiments, the control module 110 controls at least two of the first pulse modulation switches S1 to be turned on simultaneously; alternatively, the control module 110 controls at least two of the plurality of second pulse modulation switches S2 to be simultaneously turned on.

Specifically, in the structure shown in fig. 7, in order to ensure that at least two paths of massage signals exist at the same time, so as to facilitate vector combination of the massage signals, and thus adjust the direction of the combined massage signal vector through intensity adjustment of the two paths of massage signals, the control module 110 may control at least two of the first pulse modulation switches S1 to be simultaneously turned on, that is, at least two independent electrodes 131 output massage signals under the electric quantity provided by the power supply unit 121, so that at least two paths of massage signals flowing from the independent electrodes 131 to the common electrode 132 exist;

alternatively, the control module 110 may control at least two of the plurality of second pulse modulation switches S2 to be simultaneously turned on, that is, at least two of the independent electrodes 131 are grounded, so that the massage signal output by the common electrode 132 under the power supplied by the power supply unit 121 may flow to the at least two grounded independent electrodes 131, thereby implementing that there are at least two paths of massage signals flowing from the common electrode 132 to the independent electrodes 131.

It will be appreciated that the arrangement shown in figure 7 may be used to implement a massage scheme in the forward conducting state and/or the reverse conducting state.

Based on any of the above embodiments, fig. 8 is a fourth schematic structural view of the massage apparatus provided by the present invention, as shown in fig. 8, the pulse modulation unit 122 includes a plurality of fifth pulse modulation switches S5, and the fifth pulse modulation switches S5 correspond to the independent electrodes 131 one to one; one end of the fifth pulse modulation switch S5 is grounded, and the other end of the fifth pulse modulation switch S5 is connected to the corresponding independent electrode 131; the control end of the fifth pulse modulation switch S5 is connected to the control module 110; the common electrode 132 is connected to the power supply unit 121.

Specifically, the pulse modulation unit 122 may include a fifth pulse modulation switch S5 for switching the connection between each individual electrode 131 and the ground GND. Here, the fifth pulse modulation switch S5 is specifically a three-terminal structure, that is, the fifth pulse modulation switch S5 has a control terminal and two connection terminals for realizing on/off of a line, where the control terminal of the fifth pulse modulation switch S5 is connected to the control module 110, and the control module 110 can output control information, that is, a PWM signal, for the fifth pulse modulation switch S5, so as to control the fifth pulse modulation switch S5 to be turned on or turned off. Two connection ends of the fifth pulse modulation switch S5 are respectively connected to the independent electrode 131 and the ground GND, so that when the control module 110 controls the fifth pulse modulation switch S5 to be turned on, the independent electrode 131 is turned on to the ground, and when the control module 110 controls the fifth pulse modulation switch S5 to be turned off, the independent electrode 131 is turned off to the ground, and is in an isolated state.

In the structure shown in fig. 8, each independent electrode 131 is correspondingly connected with a fifth pulse modulation switch S5, and the fifth pulse modulation switches S5 are arranged in a one-to-one correspondence with the independent electrodes 131, so that the connection between each independent electrode 131 and the ground can be controlled individually. Also, in a case where the common electrode 132 is constantly connected to the power supply unit 121, in a case where any one of the fifth pulse modulation switches S5 is turned on, the common electrode 132 may generate a massage signal based on the electric energy supplied from the power supply unit 121 and transmit the massage signal to the independent electrode connected to the fifth pulse modulation switch S5 through the human body to realize a forward conduction state, with respect to the fifth pulse modulation switch S5. Moreover, for different individual electrodes 131, because the on and off modes of the fifth pulse modulation switches S5 connected to each individual electrode 131 are different, the intensity of the massage signal flowing from the common electrode 132 to each individual electrode 131 may also be different, and thus the direction of the combined massage signal vector can be flexibly changed.

According to any of the above embodiments, the pulse modulation switch in the pulse modulation unit 122 is a transistor or a mos transistor.

Here, the pulse modulation switch in the pulse modulation unit 122 may be S1 in fig. 6, S1, S2, S3, and S4 in fig. 7, or S5 in fig. 8, which is not particularly limited in this embodiment of the present invention, and it is understood that the transistor may be a contactless switch, where a base of the transistor may be regarded as a control terminal, and an emitter and a collector may be regarded as two connection terminals; a mos (Metal-Oxide-Semiconductor Field-Effect Transistor, MOSFET) Transistor is a Metal-Oxide-Semiconductor Field-Effect Transistor, a gate of the mos Transistor can be regarded as a control terminal, and a source and a drain can be regarded as two connection terminals.

Based on any of the above embodiments, the control module 110 is specifically configured to:

generating a switch driving signal and transmitting the switch driving signal to the signal generating module 120;

the signal generating module 120 is specifically configured to:

controlling the massage signal to flow to the common electrode 132 through at least two individual electrodes 131 of the at least two individual electrodes 131 based on the switching driving signal; alternatively, the first and second electrodes may be,

the massage signal is controlled to flow to at least two independent electrodes 131 of the at least two independent electrodes 131 through the common electrode 132 based on the switching driving signal.

Specifically, the control module is configured to generate and output a switch driving signal, where the switch driving signal is used to drive on or off of each pulse modulation switch in a pulse modulation unit in a signal generation module of the massage apparatus, so as to control on or off of connection between each independent electrode in an electrode assembly in the massage apparatus and the power supply unit and/or the ground, and on or off of connection between the common electrode and the power supply unit and/or the ground, thereby enabling a massage signal to flow to the common electrode through at least two independent electrodes of at least two independent electrodes in the massage apparatus, or enabling the massage signal to flow to at least two independent electrodes of at least two independent electrodes through the common electrode.

It can be understood that the number of the switch driving signals is the same as the number of the pulse modulation switches arranged in the pulse modulation unit, for example, in the structure shown in fig. 6, the common electrode is always in the grounding state, each independent electrode corresponds to one first pulse modulation switch, and at this time, the number of the switch driving signals required to be generated by the control module is the same as the total number of the independent electrodes included in the massage device; for another example, in the structure shown in fig. 7, the independent electrodes and the common electrode can be switched to be connected with the power supply unit and grounded, that is, each independent electrode corresponds to one first pulse modulation switch and one second pulse modulation switch, the common electrode corresponds to one third pulse modulation switch and one fourth pulse modulation switch, and at this time, the number of switch driving signals required to be generated by the control module is twice of the total number of electrodes included in the massage device; for another example, in the structure shown in fig. 8, the common electrode is always connected and conducted with the power supply unit, each independent electrode corresponds to one fifth pulse modulation switch, and at this time, the number of switch driving signals required to be generated by the control module is consistent with the total number of independent electrodes included in the massage device.

The one-to-one corresponding switch driving signals are set for each pulse modulation switch, so that the connection and disconnection of each pulse modulation switch can be independently controlled, the connection or disconnection flexibility between each electrode in the massage equipment and the power supply unit and/or the ground is ensured, at least two paths of massage signals flowing from the independent electrodes to the common electrode can be generated under the control of the connection structure of the electrode assembly based on the switch driving signals, or at least two paths of massage signals flowing from the common electrode to the independent electrodes are generated, the intensities of the at least two paths of massage signals are independently controllable, and the direction of the combined massage vector can be flexibly changed.

According to the massage device provided by the embodiment of the invention, at least two paths of massage signals flowing to the common electrode or flowing out from the common electrode can be generated in the massage process through the output switch driving signal, so that the combined direction-adjustable massage signal can be formed by combining the vectors of the at least two paths of massage signals, the scheme of only massaging on a connecting line between the two electrodes in the related art is broken through, the massage scheme on the surface dimension is realized, and the massage experience is improved.

Based on any one of the above embodiments, for the control module, the generating the switch driving signal includes:

Specifically, the target massage area may be a massage area which is designated by the user or generated by default by the system, and the target massage area is a two-dimensional area defined in a plane dimension; the preset massage mode may be a massage mode that is designated by the user or defaulted by the system, and the preset massage mode may refer to a direction change trend, an intensity change trend, and the like of the combined massage vector.

The target massage vector, i.e. the massage signal vector desired to be generated and combined at the current time or the current time period, may specifically include the direction and/or magnitude of the massage signal vector.

Under the condition that the target massage area is known and/or the massage mode is preset, the control module can limit the direction range of the target massage vector according to the target massage area, so that the direction of the target massage vector is determined; the direction variation trend and/or the intensity variation trend of the target massage vector can be limited according to the preset massage mode, so that the direction and/or the intensity of the target massage vector can be determined; the direction and/or intensity of the target massage vector may also be determined according to the direction range defined by the target massage area and the direction variation trend and/or intensity variation trend indicated by the preset massage mode, which is not specifically limited in the embodiment of the present invention.

The target massage vector can be decomposed into massage signals between a plurality of independent electrodes and a common electrode, and the signal intensity of each decomposed massage signal needs to be determined. It can be understood that, under the condition that the electric quantity provided by the power supply unit in the signal generation module of the massage device is fixed and unchanged, the control module can realize the intensity control of the massage signal by setting the switching duty ratio of the pulse modulation switch at the connection between the electrode through which the massage signal flows and the power supply unit or the ground.

Here, in order to synthesize the target massage vector, at least two massage signals need to be generated, and the control of the intensity of the at least two massage signals requires the connection control of at least two independent electrodes, or the connection control of at least two independent electrodes and a common electrode. For convenience of description, in the embodiment of the present invention, an electrode that needs to be subjected to connection control is referred to as an electrode to be controlled. It will be appreciated that the electrodes to be controlled in different massage device configurations may be different.

For example, in the structure shown in fig. 6, the common electrode does not need to be controlled, the electrode to be controlled includes at least two independent electrodes, and the intensity of the massage signal flowing from the at least two independent electrodes to the common electrode can be controlled by setting the target duty ratios respectively corresponding to the at least two independent electrodes; in the structure shown in fig. 7, the electrodes to be controlled include at least two independent electrodes and a common electrode, and by setting the target duty ratios corresponding to the at least two independent electrodes and the common electrode, the intensity of the massage signal flowing from the at least two independent electrodes to the common electrode can be controlled, or the intensity of the massage signal flowing from the common electrode to the at least two independent electrodes can be controlled; in the structure shown in fig. 8, the common electrode does not need to be controlled, the electrode to be controlled includes at least two independent electrodes, and the intensity of the massage signal flowing from the common electrode to the at least two independent electrodes can be controlled by setting the target duty ratios respectively corresponding to the at least two independent electrodes.

After the target duty ratios respectively corresponding to the electrodes to be controlled are obtained, the control module can generate switch driving signals respectively corresponding to the electrodes to be controlled, so that the intensity control of the massage signals flowing through the electrodes to be controlled is realized, and the target massage vectors are obtained through combination.

Based on any one of the above embodiments, for the control module, the determining the target massage vector based on the target massage area and/or the preset massage mode includes:

Specifically, the massage vectors at the previous time may be obtained by combining the massage vectors after actual measurement. Aiming at the respective voltage values of the massage signals flowing through the at least two independent electrodes detected at the previous moment and the directions of the massage signals indicated by the respective connecting lines of the at least two independent electrodes and the common electrode, at least two paths of massage signals can be combined, so that the massage vector at the previous moment is obtained.

The target massage vector may be updated every moment, and the user may feel the change of the massage action when receiving the massage by updating the target massage vector every moment. In order to ensure that the change of the massage actions perceived by the user is smooth, the massage vectors at the previous moment before the current moment can be combined when determining the target massage vector at the current moment. For example, the direction and/or intensity of the target massage vector may be determined on the basis of the massage vector at the previous time in conjunction with the direction change tendency and/or intensity change tendency indicated by the preset massage pattern.

Based on any of the above embodiments, the determining the target massage vector based on the target massage area and/or a preset massage mode and the massage vector at the previous time includes:

determining the size of the target massage vector based on the size of the massage vector at the previous moment and a preset massage strength range in the preset massage mode;

Specifically, the preset massage mode may define a range of massage force, such as 1 gear, 2 gears, 3 gears, and the like, each gear may correspond to a range of massage force, and the massage force here may be represented as a voltage. The size of the target massage vector at the current moment can be limited according to the preset massage force range included in the preset massage mode. In order to ensure the smoothness of the massage manipulation perceived by the user, the determination of the size of the target massage vector may be implemented on the basis of the size of the massage vector at the previous moment, and specifically, the size of the target massage vector may be determined by adjusting the size of the massage vector at the previous moment within a preset massage force range.

In addition, the target massage area defines a direction range of the target massage vector, and in order to ensure the smoothness of the massage manipulation perceived by the user, the determination of the direction of the target massage vector may be performed on the basis of the direction of the massage vector at the previous time, and specifically, the direction of the target massage vector may be determined by adjusting the direction of the massage vector at the previous time within the target massage area on the basis of the direction of the massage vector at the previous time.

Based on any one of the above embodiments, for the control module, determining the target duty ratios respectively corresponding to the electrodes to be controlled based on the target massage vector includes:

Specifically, in order to make the massage vector synthesized by the formed massage signals coincide with the target massage vector in both direction and magnitude, it is necessary to first select the individual electrodes for transmitting the massage signals from the electrode assembly as the individual electrodes to be controlled. For example, in the structure shown in fig. 6, 3 independent electrodes coexist, and at least two independent electrodes need to be selected from the 3 independent electrodes as the independent electrodes to be controlled so as to be able to form at least two paths of massage signals to synthesize the target massage vector.

Here, for the selection of the independent electrodes to be controlled, it is necessary to refer to the connecting lines between each independent electrode and the common electrode, and the direction of the target massage vector, for example, fig. 9 is a vector combination schematic diagram provided by the present invention, as shown in fig. 9, the dashed arrows indicate the target massage vector, and according to the direction of the target massage vector and the connecting lines between each independent electrode 131 and the common electrode 132, the target massage vector is in the sector area enclosed by the independent electrodes A, B and the common electrode 132, that is, the target massage vector can be obtained by combining the massage signals transmitted between the independent electrodes A, B and the common electrode 132, so that the independent electrode A, B can be selected from the independent electrodes A, B, C as the independent electrode to be controlled.

After the independent electrodes to be controlled are determined, the intensity of the massage signal required to be transmitted by each independent electrode to be controlled can be split according to the size of the target massage vector, so that the target duty ratio of each independent electrode to be controlled is determined.

It is understood that, in the case that the electrode to be controlled includes only the independent electrode to be controlled and does not include the common electrode, the target duty cycle of the electrode to be controlled is determined, i.e., the target duty cycle determination of the electrode to be controlled is completed, and in the case that the electrode to be controlled includes not only the independent electrode to be controlled but also the common electrode, the target duty cycle of the common electrode may be 100%, i.e., the common electrode is continuously connected to the power supply unit or is continuously grounded.

Based on any of the above embodiments, the determining the target duty cycle of the individual electrode to be controlled based on the magnitude of the target massage vector includes:

Specifically, as shown in fig. 9, after the target massage vector is determined, the target massage vector may be decomposed into two vectors in the direction of the connecting line between the two independent electrodes to be controlled and the common electrode, i.e., the solid arrows in fig. 9, which are herein denoted as target decomposition vectors.

For each target decomposition vector, the size of the target decomposition vector, that is, the voltage value of the massage signal required to be transmitted by the corresponding to-be-controlled independent electrode, can determine the target duty ratio of the corresponding to-be-controlled independent electrode according to the size of the target decomposition vector. For example, if the magnitude of the target decomposition vector of an individual electrode to be controlled, i.e., the voltage value of the massage signal to be transmitted is V1, and the voltage value output by the power supply unit is V0, the target duty ratio of the individual electrode to be controlled is V1/V0.

Based on any embodiment, under the condition that two independent electrodes to be controlled exist, the time period in which the high level of the switch driving signal of the first independent electrode to be controlled is positioned is contained in the time period in which the high level of the switch driving signal of the second independent electrode to be controlled is positioned;

Specifically, in the case where there are two independent electrodes to be controlled, the magnitudes of the target duty ratios of the two independent electrodes to be controlled may be compared, and one independent electrode to be controlled whose target duty ratio is smaller is designated as a first independent electrode to be controlled, and one independent electrode to be controlled whose target duty ratio is larger is designated as a second independent electrode to be controlled.

In order to ensure that two paths of massage signals respectively transmitted by two independent electrodes to be controlled have the condition of simultaneous transmission so as to facilitate the combination of the massage signals, when the switch driving signals of the two independent electrodes to be controlled are generated, the time period of the high level in the switch driving signal of the first independent electrode to be controlled is included in the time period of the high level in the switch driving signal of the second independent electrode to be controlled, for example, fig. 10 is a schematic diagram of the switch driving signals provided by the present invention, in fig. 10, PWM1 represents the switch driving signal of the first independent electrode to be controlled, and PWM2 represents the switch driving signal of the second independent electrode to be controlled.

Based on any of the above embodiments, in the structure shown in fig. 9, the at least two independent electrodes 131 are specifically three independent electrodes 131, that is, the independent electrodes A, B, C in fig. 9, the three independent electrodes 131 are respectively disposed at three vertices of an equilateral triangle, and the common electrode 132 is disposed at the center of gravity of the equilateral triangle, in this case, the control module is specifically configured to:

Specifically, in the arrangement mode of the electrode assembly, every two independent electrodes and the common electrode form a 120-degree sector massage area, and the three independent electrodes are combined in pairs to form a perfect circle with the common electrode as the center. In this case, the switch driving signals corresponding to the three independent electrodes can be generated by using a Space Vector Pulse Width Modulation (SVPWM) technique for generating a circular rotating magnetic field, so as to implement a massage scheme for a circular region with the common electrode as a center.

Under the SVPWM control, the three independent electrodes A, B, C in fig. 9 can respectively realize the conduction between a single independent electrode and the common electrode and the conduction between two or three independent electrodes and the common electrode at the same time in different time periods. It can be understood that, in the case that a single independent electrode is conducted with the common electrode, a massage signal vector whose direction is not changed and whose magnitude is changed is formed; in the case where two or three individual electrodes are simultaneously conducted with the common electrode, two or three massage signals may be combined into one massage signal vector, where the direction and magnitude of the massage signal vector may be varied according to the magnitude of the two or three massage signals.

Based on any of the above embodiments, fig. 11 is a schematic flow chart of a signal output method provided by the present invention, as shown in fig. 11, the method includes:

step 1110, generating a switch driving signal;

step 1120, controlling a massage signal to flow to a common electrode through at least two independent electrodes of at least two independent electrodes based on the switch driving signal; alternatively, the first and second electrodes may be,

It can be understood that, the functions of the method provided by the embodiment of the present invention and the functions of the control module in the above embodiments are the same, and may be referred to correspondingly, which is not described herein again.

According to the method provided by the embodiment of the invention, at least two paths of massage signals flowing to the common electrode or flowing out from the common electrode can be generated in the massage process through the output switch driving signal, so that the combined direction-adjustable massage signal can be formed by combining the vectors of the at least two paths of massage signals, the scheme of only massaging on the connecting line between the two electrodes in the related technology is broken through, the massage scheme on the plane dimension is realized, and the massage experience is improved.

Based on any of the above embodiments, step 1110 includes:

Based on any of the above embodiments, the determining a target massage vector based on the target massage area and/or the preset massage mode includes:

Based on any of the above embodiments, the determining, based on the target massage vector, the target duty ratios respectively corresponding to the electrodes to be controlled includes:

Based on any embodiment, under the condition that two independent electrodes to be controlled exist, the period in which the high level of the switch driving signal of the first independent electrode to be controlled exists is contained in the period in which the high level of the switch driving signal of the second independent electrode to be controlled exists;

In accordance with any of the above embodiments, in a case where the at least two independent electrodes are three independent electrodes, the three independent electrodes are respectively disposed at three vertices of an equilateral triangle, and the common electrode is disposed at a center of gravity of the equilateral triangle, the step 1110 includes:

Based on any of the above embodiments, the signal output method provided in the above embodiments may be applied to the processing module of the massage apparatus provided in the above embodiments, and the combination arrangement of the plurality of independent electrodes and the common electrode in the massage apparatus, in combination with the application of the signal output method, enables the massage apparatus to realize massage in the planar dimension. The massage equipment can be used as a cervical vertebra massage instrument and also can be used as a waist massage instrument.

Compared with the scheme that the massage can be only carried out on the connecting line position of the electrode plates, the embodiment of the invention does not follow the traditional improvement thought, namely the area of the electrode plates is increased or the number of the electrodes is increased, but the massage aiming at the whole surface is realized only by using a small number of electrodes through the combined arrangement of a plurality of independent electrodes and a common electrode, the massage direction and the massage force can be adjusted randomly, and the massage manipulation and the massage body feeling are enriched.

By applying the signal output method, the massage equipment can control the voltage and the current direction more finely, the EMS effect is better and finer, the dynamic adjustment of the massage area is realized, stimulation is not performed on a certain fixed point singly any more, the pricking feeling of the human body caused by long-time EMS effect on the local area is avoided, and the massage effect and the use experience are improved.

In the signal output method, the target massage area and/or the preset massage mode can be manually set, so that the dynamic adjustment of massage points and corresponding force based on manual setting is realized, a hand massage scheme is simulated, a massage prescription of a rehabilitation physiotherapy level can be set, and the efficacy of wearable EMS equipment is improved.
