Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

It should be noted that the terms "comprising" and "having" and any variations thereof in the embodiments of the present application and the accompanying drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.

The embodiment of the application discloses a fascia gun which can solve the problem of power supply of an internal circuit of a massage head and can independently supply power to the internal circuit of the massage head. The following will describe in detail.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a fascia gun according to an embodiment of the application. As shown in fig. 1, the fascia gun 100 includes: a body 10 and a massage head 20. Wherein:

the fuselage 10 may include: a magnet 11, a controller 12 and a motor 13. It should be noted that the body 10 may further include a battery 14, a transmission rod 15, a piston assembly 16, and the like.

The magnet 11 may be disposed at one end of the body 10 connected to the massage head 20 for generating a magnetic field. In the embodiment of the present application, the magnet 11 may include an electromagnet or a permanent magnet, but is not limited thereto. When the magnet 11 comprises an electromagnet, the battery 14 may supply power to the conductive windings of the electromagnet.

The controller 12 may be coupled to the motor 13 and may be used to control the rotation of the motor 13. The controller 12 may include, but is not limited to, a single chip microcomputer, a micro control unit (Micro Control Unit, MUC), and the like.

The motor 13 is rotatable under the control of the controller 12 to drive the massage head 20 to perform reciprocating motion by the rotation. The motor 13 and the massage head 20 may be connected through a transmission mechanism, and an exemplary conventional mechanism may include a transmission rod 15 and a piston assembly 16 as shown in fig. 1, the motor 13 may be connected to one end of the transmission rod 15, the other end of the transmission rod 15 may be connected to one end of the piston assembly 16, and the other end of the piston assembly 16 may be connected to the massage head 20. When the motor 13 rotates under the control of the controller 12, the transmission rod 15 can be driven to reciprocate along the length direction of the machine body 10, so that the massage head 20 is driven to reciprocate along the length direction of the machine body 10 through the piston assembly 16.

The massage head 20 may include: a coil 21 and an operating circuit 22.

A coil 21, which is provided in the massage head 20, for generating an induced voltage and/or an induced current based on electromagnetic induction when the massage head 20 performs a reciprocating motion. The coil 21 may follow the movement of the massage head 20 as the massage head 20 performs a reciprocating movement under the drive of the piston assembly 16. The magnet 11 is provided at one end of the massage head 20 connected to the body 10, and the position of the magnet 11 can be kept fixed while the massage head 20 moves. Therefore, the coil 21 changes its distance from the magnet during the following movement of the massage head 20, and the magnetic induction intensity changes, while the area enclosed by the coil is unchanged, so that the magnetic flux passing through the coil 21 changes.

The operation circuit 22 is electrically connected to the coil 21 and is operable to operate based on the induced voltage and/or the induced current generated by the coil 21. The working circuit 22 and the coil 21 may form a circuit loop, and the coil 21 may be used as a power source to supply power to the working circuit 22. The operating circuit 22 may include one or more loads, such as resistors, etc.

In order to better describe the working principle of the fascia gun according to the embodiment of the application, please refer to fig. 2, and fig. 2 is an exemplary diagram of a relative positional relationship between a coil and a magnet according to the embodiment of the application. As shown in fig. 2, the magnetic induction wire may pass through the coil 21. When the massage head 20 is far from the body 10, the magnetic induction intensity at the coil 21 is weaker, and the magnetic flux passing through the coil 21 is smaller. When the massage head 20 is close to the body 10, the magnetic induction intensity at the coil 21 is strong, and the magnetic flux passing through the coil 21 is large. It can be seen that when the massage head 20 performs a reciprocating motion along the length direction of the body 10, the massage head 20 reciprocates in a direction away from the body 10 and in a direction toward the body 10, and the magnetic flux passing through the coil 21 can be changed. When the magnetic flux in the coil 21 changes, an induced voltage and/or an induced current can be generated in a circuit loop formed by the coil 21 and the working circuit 22, so that the working circuit 22 can work normally under the driving of the induced voltage and/or the induced current. That is, when the fascia gun 100 is operated, the coil 21 can be used as a power source to supply power to the operating circuit 22, thereby solving the power supply problem of the internal circuit of the massage head 20. In addition, the circuit in the massage head 20 composed of the coil 21 and the working circuit 22 is independent from the circuit in the body 10 composed of the battery 14, the controller 12 and the motor 13, that is, there is no relation of electrical connection between the internal circuit of the massage head 20 and the internal circuit of the body 10. Therefore, even when the fascia gun 100 is in an operating state, the high-frequency vibration of the massage head 20 does not affect the power supply of the coil 21 to the operating circuit 22, and the operating stability of the internal circuit of the massage head 20 can be improved; in addition, since there is no electrical connection between the internal circuit of the massage head 20 and the internal circuit of the body 10, the high-frequency vibration does not affect the service life of the power supply circuit.

Optionally, the working circuit 22 may include a heat generating module 221 and/or a light emitting module 222. Referring to fig. 3, fig. 3 is a schematic diagram of an internal circuit of a massage head according to an embodiment of the application. As shown in fig. 3, the circuit may include a coil 21 and an operating circuit 22 electrically connected to the coil 21.

The heating module 221 may be used to generate heat under the driving of the induced voltage and/or the induced current generated by the coil 21. Illustratively, the heat generating module 221 may include a heat generating sheet, a heat generating filament, etc., but is not limited thereto. That is, the heating module 221 can generate heat when the fascia gun 100 is in an operating state, so that the fascia gun 100 can provide a vibration massage function and a hot compress function at the same time, thereby being beneficial to improving the massage effect of the fascia gun.

The light emitting module 222 may be used to emit light under the driving of the induced voltage and/or the induced current generated by the coil 21. By way of example, the light emitting module 222 may include a single light granule, a light strip composed of a plurality of light granules, and the like, but is not limited thereto. That is, the light module 222 may illuminate when the fascia gun 100 is in operation to indicate that the fascia gun 100 is operating by the light module 222, and may also provide additional illumination to facilitate use of the fascia gun in a less light scene.

In the embodiment of the present application, when the fascia gun 100 is in the working state, the high-frequency reciprocating motion of the massage head 20 can make the coil 21 in the massage head 20 cut the magnetic field generated by the magnet 11, so that the magnetic flux in the coil 21 changes, and the induced voltage and/or the induced current are generated in the coil 21. Based on the induced voltage and/or the induced current, the coil 21 can supply power to the working circuit 22, such as the heating module 221 or the light emitting module 222, so as to provide a stable power supply for the working circuit 22 in the massage head 20, thereby solving the power supply problem of the internal circuit of the massage head.

In one embodiment, referring to fig. 4, fig. 4 is a schematic structural diagram of an internal circuit of another massage head according to an embodiment of the present application. As shown in fig. 4, the internal circuit may include a coil 21 and an operating circuit 22 electrically connected to the coil 21. Wherein the operating circuit 22 may comprise: a heating module 221, a switching module 223, and a temperature sensor 224.

The heating module 221 may be used to generate heat under the driving of the induced voltage and/or the induced current generated by the coil 21.

The temperature sensor 224 is electrically connected to the coil 21, and the coil 21 supplies power to the temperature sensor 224. The temperature sensor 224 may be used to detect a heat generation temperature of the heat generation module 221.

The switch module 223 may be electrically connected to the heat generating module 221 for switching on/off states. When the switching module 223 is switched to the on state, a loop formed between the heating module 221 and the coil 21 is turned on; when the switching module 223 is switched to the off state, a loop formed between the heat generating module 221 and the coil 21 is turned off. In an embodiment of the present application, the switching of the switch module 223 between the on state and the off state may be controlled based on the heat generation temperature detected by the temperature sensor 224.

Optionally, the switch module 223 may be configured to switch to an off state to disconnect the loop between the coil 21 and the heat generating module 221 when the heat generating temperature detected by the temperature sensor 224 is greater than a first temperature threshold. The first temperature threshold may be set according to actual service requirements, for example, a temperature higher than the human body temperature, for example, 40 ℃ and 45 ℃, but is not limited thereto. That is, when the heating temperature of the heating module 221 is too high, the switch module 223 can timely disconnect the power supply to the heating module 221, so that the heating module 221 does not generate heat any more, so as to reduce the temperature of the massage head 20, and effectively avoid scalding the user of the fascia gun 100.

Optionally, the switch module 223 may be further configured to switch to a conducting state to conduct a loop between the coil 21 and the heat generating module 221 when the heat generating temperature detected by the temperature sensor 224 is lower than the second temperature threshold. The second temperature threshold may be set according to actual service requirements, and may be set to the same value as the first temperature threshold or a different value. For example, the second temperature threshold may be set to a temperature value lower than the body temperature of the human body, such as 34 ℃, 36 ℃, or the like, but is not limited thereto. That is, when the temperature of the heat generating module 221 is too low, the switch module 223 may supply power to the heat generating module 221 in time, so that the heat generating module 221 is powered up to generate heat, so as to increase the temperature of the massage head 20.

In the embodiment of the present application, the switch module 223 is switched between the on state and the off state according to the heating temperature detected by the temperature sensor 224, so that the temperature of the heating module 221 can be maintained within a preset temperature range, and thus the temperature of the massage head 20 can be maintained within the preset temperature range, and a comfortable hot compress effect can be provided.

In one embodiment, referring to fig. 5, fig. 5 is a schematic diagram illustrating an internal circuit of another massage head according to an embodiment of the present application. As shown in fig. 5, the internal circuit may include a coil 21 and an operating circuit 22 electrically connected to the coil 21. Wherein the operating circuit 22 may comprise: a light emitting module 222.

The light emitting module 222 may be used to emit light under the driving of the induced voltage and/or the induced current generated by the coil 21. Optionally, the light emitting module 222 may be configured to output light indicating information, where the light indicating information may be configured to indicate a working gear of the massage head 20, and the working gear of the massage head 20 is in positive correlation with a speed at which the massage head 20 performs the reciprocating motion. The fascia gun 100 can provide at least two different operating positions for user selection, different operating positions can correspond to different movement speeds of the massage head 20, and the higher the operating position, the faster the movement speed of the massage head 20 when performing reciprocating movement. Wherein, the light indication information can include, but is not limited to: the light emitting module 222 emits light at a luminance, a flicker frequency, the number of emitted light particles, and the like, but is not limited thereto.

Optionally, the light indication information output by the light emitting module 222 may include a light emitting brightness of the light emitting module 222, and the light emitting brightness may be in positive correlation with the working gear of the massaging head 20. The induced electromotive force e=n×ΔΦ/Δt generated by the change of the magnetic flux of the coil 21, n being the number of turns of the coil 21, ΔΦ/Δt being the amount of change of the magnetic flux per unit time, that is, the rate of change of the magnetic flux. It can be seen that, when the operating gear of the massage head 20 is in positive correlation with the speed at which the massage head 20 performs the reciprocating motion, the higher the operating gear of the massage head 20, the faster the moving speed at which the reciprocating motion is performed, the higher the rate of change of the magnetic flux passing through the coil 21, the greater the induced electromotive force E generated by the coil 21, the greater the induced current and/or the induced voltage generated, and the higher the brightness of the light emitting module 222 emitted by the driving of the induced current and/or the induced voltage. Accordingly, the light emitting module 222 may indicate the operating range of the massage head 20 by the light emitting brightness.

In one embodiment, the magnet 11 may comprise an electromagnet. When the magnet 11 includes an electromagnet, the value of the current passing through the electromagnet can be adjusted by the controller 12, thereby adjusting the magnetic induction intensity generated by the electromagnet. Magnetic induction intensity b1=μ of magnetic field generated by electromagnet ₀ IN/L, where μ ₀ The constant is that I is the current flowing through the electromagnet, N is the number of spool turns of the conductive winding of the electromagnet, and L is the spool length of the conductive winding. The larger the value of the current flowing through the electromagnet, the larger the magnetic induction intensity B1 generated by the electromagnet. Magnetic flux Φ=b1×s passing through the coil 21 in the massage head 20Where S is the area of the coil 21. Therefore, when the area of the coil 21 is unchanged, the larger the magnetic induction intensity B1 generated by the electromagnet, the higher the rate of change of the magnetic flux Φ of the coil 21 per unit time, the larger the electromotive force E generated by the coil 21 due to the change of the magnetic flux, and the larger the induced current and/or the induced voltage generated. Accordingly, the smaller the magnetic induction intensity B1 generated by the electromagnet, the smaller the induced current and/or the induced voltage generated by the coil 21. It can be seen that the voltage value of the induced voltage and/or the current value of the induced current generated by the coil 21 can be adjusted by the controller 12 adjusting the current value through the electromagnet.

Alternatively, when the operating circuit includes the heat generating module 221, the controller 12 may also be configured to detect a first target temperature indicated by the temperature adjustment operation. The temperature adjustment operation may be input by a user, for example, one or more temperature adjustment keys may be further provided on the body 10 of the fascia gun 100, each temperature adjustment key corresponding to a preset temperature value. The user-entered temperature adjustment operation may include pressing a temperature adjustment key, and the pressed temperature adjustment key may generate a temperature adjustment signal, which may include a temperature value corresponding to the pressed temperature adjustment key. The controller 12 may receive a temperature adjustment signal transmitted by the pressed temperature adjustment key, and read a temperature value from the received temperature adjustment signal as the first target temperature. Alternatively, the fascia gun 100 may further include a communication module, through which the fascia gun 100 may establish a communication connection with a terminal device such as a smart phone, a smart tablet, or the like. The temperature adjustment operation may include a user selecting/inputting a desired temperature value on the terminal device, the terminal device may transmit the temperature value desired by the user to the communication module of the fascia gun 100, and the controller 12 may determine the temperature value received by the communication module as the first target temperature value, but is not limited thereto.

In the embodiment of the present application, the heating temperature of the heating module 221 may be related to the current value of the induced current flowing through the heating module 221. Illustratively, the heat generated by the heat generating module 221 is q=i ² Rt, wherein i is the current value of the induced current flowing through the heat generating module 221, R is the resistance value of the heat generating module 221, and t is the hairThe energization time period of the thermal module 221. As can be seen from the description of the relationship between the magnetic induction intensity generated by the electromagnet and the induced current generated by the coil 21 in the foregoing embodiment, the current value of the induced current generated by the coil 21 can be adjusted by adjusting the current value flowing through the electromagnet, and the heat generation temperature of the heat generation module 221 can be correlated with the current value of the induced current generated by the coil 21. Accordingly, the correspondence relationship between the value of the current flowing through the electromagnet and the heat generation temperature of the heat generation module 221 may be calibrated in advance.

When the first target temperature is detected, the controller 12 may determine a first current value corresponding to the first target temperature according to a pre-calibrated correspondence, and adjust the current value flowing through the electromagnet to the first current value, so that the coil 21 generates the first induced voltage and/or the first induced current based on electromagnetic induction when the current flowing through the electromagnet is the first current value. The heat generating module 221 generates heat under the driving of the first induced voltage and/or the first induced current, and the heat generating temperature of the heat generating module 221 can be controlled at the first target temperature. Therefore, the fascia gun 100 can flexibly adjust the heating temperature of the heating module 221 by controlling the current flowing through the electromagnet, which is beneficial to further improving the massaging effect of the fascia gun 100.

Optionally, the controller 12 may also be configured to detect a current operating position of the massage head 20, and the reciprocating motion may be performed at different frequencies when the massage head 20 is in different operating positions. The frequency at which the massage head 20 performs the reciprocating motion may be related to the rotational speed of the motor, and thus, the controller 12 may acquire the rotational speed of the motor corresponding to the current operating gear of the massage head 20, thereby determining the first frequency of the massage head 20 when performing the reciprocating motion corresponding to the current operating gear according to the rotational speed of the motor. The induced electromotive force e=n×ΔΦ/Δt=b1×lv of the coil 21 due to the magnetic flux change, wherein B1 is the magnetic induction intensity of the magnetic field generated by the electromagnet, l is the length of the coil 21, and v is the movement speed of the coil 21 when performing the reciprocating movement; v is related to the frequency at which the coil 21 performs the reciprocating motion. It can be seen that the moving speed of the massage head 20 may be related to the induced electromotive force E generated by the coil 21, and thus the frequency at which the massage head 20 performs the reciprocating motion may affect the current value of the induced current generated by the coil 21, thereby affecting the heat generation temperature of the heat generation module 221. It can be seen that when the fascia gun 100 provides different working positions, the second current value flowing through the electromagnet can be determined according to the first speed of the massage head 20 corresponding to the current working position and the first target temperature of the heat generated by the heat generating module 221. For example, the controller 12 may determine the current value of the induced current to be generated by the coil 21 according to the first target temperature, and then determine the induced electromotive force to be generated by the coil 21 according to the current value to be generated by the coil 21; the magnetic induction intensity to be generated by the electromagnet can be determined based on the induced electromotive force to be generated by the coil 21 and the first speed of the massage head 20, so that the second current value to be passed through the electromagnet can be determined based on the magnetic induction intensity to be generated by the electromagnet.

After determining the second current value, the controller 12 may adjust the current value flowing through the electromagnet to the second current value, so that the coil 21 generates the second induced voltage and/or the second induced current based on electromagnetic induction when the current flowing through the electromagnet is the second current value. The heat generating module 221 generates heat under the driving of the second induced voltage and/or the second induced current, and the heat generating temperature of the heat generating module 221 can be controlled at the first target temperature. It can be seen that, when the fascia gun 100 can provide different working positions for the user to select, the fascia gun 100 can also adjust the current value flowing through the electromagnet according to the movement speed of the massage head 20 in the current working position, so that the heating temperature of the heating module 221 can be more accurately adjusted to the target temperature selected by the user, which is beneficial to improving the accuracy of the temperature adjustment of the massage head.

Optionally, when the operating circuit 22 includes the light emitting module 222, the controller 12 may also be configured to detect a first target brightness for the brightness adjustment operation. Similar to the above-described temperature adjustment operation, the brightness adjustment operation may also be input by the user, and the following description will be omitted. The light emitting brightness of the light emitting module 222 may be related to the current value of the induced current flowing through the light emitting module 222, and the greater the current value flowing through the light emitting module 222, the higher the light emitting brightness of the light emitting module 222. Therefore, the current value of the induced current generated by the coil 21 can be adjusted by adjusting the current value flowing through the electromagnet, so that the light emitting brightness of the light emitting module 222 can be adjusted.

When the first target brightness is detected, the controller 12 may determine a third current value corresponding to the first target brightness according to a pre-calibrated correspondence between the current value flowing through the electromagnet and the light emitting temperature of the light emitting module 222, and adjust the current value flowing through the electromagnet to the above third current value, so that the coil 21 generates the third induced voltage and/or the third induced current based on electromagnetic induction when the current flowing through the electromagnet is the third current value. The light emitting module 222 emits light under the driving of the third induced voltage and/or the third induced current, and the light emitting brightness of the light emitting module 222 can be controlled at the first target brightness. Therefore, the fascia gun 100 can flexibly adjust the light-emitting brightness of the light-emitting module 222 by controlling the current value flowing through the electromagnet, so that the user can fully utilize the lighting function of the light-emitting module 222, which is beneficial to improving the usability and convenience of use of the fascia gun 100.

Alternatively, the controller 12 may be further configured to detect a current operating position of the massage head 20, and as can be seen from the description of the foregoing embodiment, the movement speed of the massage head 20 when performing the reciprocating movement may affect the current value of the induced current generated by the coil 21. Accordingly, the controller 12 may acquire a second frequency at which the massage head 20 performs the reciprocating motion corresponding to the current operating gear, and determine a fourth current value flowing through the electromagnet according to the second frequency and the first target brightness of the light emitted from the light emitting module 222. After the controller 12 adjusts the current value flowing through the electromagnet to the fourth current value, the coil 21 may generate the fourth induced voltage and/or the fourth induced current based on electromagnetic induction when the current flowing through the electromagnet is the fourth current value, and the light emitting module 222 emits light under the driving of the fourth induced voltage and/or the fourth induced current, so as to control the light emitting brightness of the light emitting module 222 to the first target brightness. It can be seen that, when the fascia gun 100 can provide different gear positions for the user to select, the fascia gun 100 can also adjust the current value flowing through the electromagnet according to the moving speed of the massage head 20 in the current working gear position, so that the light-emitting brightness of the light-emitting module 222 can be more accurately adjusted to the target brightness selected by the user, which is beneficial to improving the accuracy of brightness adjustment.

In one embodiment, the magnet 11 may comprise a permanent magnet, which may generally comprise a magnetically constant material, and the magnetic induction B2 produced by the permanent magnet is generally constant. The induced electromotive force e=b2×lv, i generated by the change of the magnetic flux of the coil 21 is the length of the coil 21, v is the moving speed when the coil 21 cuts the magnetic induction line, and v is related to the frequency when the coil 21 performs the reciprocating motion. In the case where the magnetic induction intensity B2 generated by the permanent magnet is constant, the induced electromotive force generated by the coil 21 can be controlled by controlling the frequency of movement of the coil 21. Accordingly, the controller 21 may adjust the voltage value of the induced voltage and/or the current value of the induced current generated by the coil 21 by controlling the frequency at which the massage head 20 performs the reciprocating motion.

Optionally, when the operating circuit 22 includes the heat generating module 221, the controller 12 may also be configured to detect a second target temperature indicated by the temperature adjustment operation. The correspondence between the heating temperature of the heating module 221 and the movement frequency of the massage head 20 (i.e., the movement frequency of the coil 21) may be calibrated in advance, and the controller 12 may determine the third frequency when the massage head 20 performs the reciprocating movement corresponding to the second target temperature according to the correspondence. The controller 12 may determine a first rotation speed of the motor 13 according to a third frequency when the massage head 20 performs the reciprocating motion, and control the motor 13 to rotate at the first rotation speed, so that the massage head 20 may perform the reciprocating motion according to the third frequency under the driving of the motor 13. When the massage head 20 performs the reciprocating motion at the third frequency according to the driving coil 21, the fifth induction voltage and/or the fifth induction current may be generated based on the electromagnetic induction, so that the heat generating module 221 may generate heat under the driving of the fifth induction voltage and/or the fifth induction current, and the heat generating temperature of the heat generating module 221 may be controlled at the second target temperature. It can be seen that, when the magnet 11 included in the fascia gun 100 is a permanent magnet, the heating temperature of the heating module 221 can be flexibly adjusted by controlling the movement frequency of the massaging head 20 to perform the reciprocating movement, which is beneficial to further improving the massaging effect of the fascia gun 100.

Optionally, when the working circuit 22 includes the light emitting module 222, the controller 12 may be further configured to detect a second target brightness indicated by the brightness adjustment operation. The correspondence between the light emitting brightness of the light emitting module 222 and the movement frequency of the massage head 20 may be calibrated in advance, and the controller 12 may determine a fourth frequency at which the massage head 20 performs the reciprocating movement corresponding to the second target brightness according to the correspondence. The controller 12 may determine a second rotation speed of the motor 13 according to a fourth frequency when the massage head 20 performs the reciprocating motion, and control the motor 13 to rotate at the second rotation speed, so that the massage head 20 may perform the reciprocating motion according to the fourth frequency under the driving of the motor 13. When the massaging head 20 drives the coil 21 to perform the reciprocating motion at the fourth frequency, the sixth induced voltage and/or the sixth induced current can be generated based on the electromagnetic induction, so that the light emitting module 222 can generate light under the driving of the sixth induced voltage and/or the sixth induced current, and the light emitting brightness of the light emitting module 222 can be controlled at the second target brightness. It can be seen that, when the magnet 11 included in the fascia gun 100 is a permanent magnet, the movement frequency of the reciprocating movement of the massage head 20 can be controlled to flexibly adjust the light emitting brightness of the light emitting module 222, so that the user can fully utilize the lighting function of the light emitting module 222, which is beneficial to improving the usability and convenience of use of the fascia gun 100.
