Description

The present invention belongs to the technical field of massage and fitness equipment, and more specifically, to a fascia gun with heating or heating/cooling functions.

There is a treatment that has been developed to relieve stiffness and pain and allow joints to move smoothly by performing massage treatments that target the fascia that covers human muscles, removing adhesions that have formed between the fascia and muscles, or between pieces of fascia themselves, and restoring the fascia to its original elastic state. Fascia guns are a device used for this purpose. Some fascia guns are equipped with a heating mechanism or heating/cooling function in the massage head to enhance the massage effect.

Conventional fascia guns equipped with a heated massage head required a battery to be installed in the massage head to power the heating mechanism, separate from the battery in the main unit. However, due to the small size of the massage head, there was a limit to the capacity of the battery that could be installed, and the power supply time was very short. This meant that the massage head had to be charged separately, which was less convenient.

Fascia guns equipped with a massage head capable of both heating and cooling are already on the market, but most of these have a separate battery installed in the massage head or are equipped with a rechargeable battery, which means they have the drawbacks of a short operating time and low heating and cooling effects.

The present invention was made in consideration of the above circumstances, and its main objective is to provide a more convenient fascia gun with a simple configuration and a heating function or a heating/cooling function.

According to one aspect of the present invention, a fascia gun is provided that includes a main body and a massage head. The main body includes a support that slidably connects the massage head to the main body, a drive unit that is connected to the support unit via a connecting member and slides on the support unit, a power supply unit that supplies power to the drive unit, a first control unit that controls the drive unit and the massage head, and a conductive unit that is connected to the power supply unit and is provided in the support unit so as to be electrically connected to the massage head. The massage head includes a head unit that is pressed by a user against an affected area, a rod unit that is connected to the support unit by a screw engagement and connects the head unit to the main body, and the body of the rod unit. The massage head further includes a heating/cooling unit having a heating function and a cooling function, a temperature sensor that detects the temperature of the massage head, and a second control unit that processes a signal from the temperature sensor to control the heating/cooling unit, thereby controlling the temperature of the massage head. The conductive unit includes a plurality of concentric conductive rings that are arranged to be spaced apart from each other in accordance with the spacing between the connection pins, and the number of the rings is equal to or greater than the number of the connection pins. When the massage head is coupled to the main body, the connection pins are electrically connected to the conductors, and power is supplied from the power supply unit to the massage head. The massage head further includes a heating/cooling unit having a heating function and a cooling function, a temperature sensor that detects the temperature of the massage head, and a second control unit that processes a signal from the temperature sensor to control the heating/cooling unit, thereby controlling the temperature of the massage head.

According to one embodiment, the massage head further includes an exhaust fan that dissipates heat generated by the heating and cooling unit in the cooling mode.

According to another embodiment, the second control unit can control the temperature of the massage head in multiple stages by comparing the detected temperature of the massage head with multiple preset thresholds.

According to yet another embodiment, the heating and cooling unit includes a Peltier element that switches between one-side heating and one-side cooling by switching the supplied current between positive and negative.

The fascia gun according to one embodiment further includes a relay member interposed between the power supply unit and the support unit, relaying electrical connections between the power supply unit and the drive unit and the support unit, the relay member including a fixed portion fixed to the main body and a second connecting member coupled to the first connecting member, the fixed portion having a base, a protruding portion erected from one side of the base toward the support unit, and a plurality of stripe-shaped first conductive portions disposed on the top surface of the protruding portion and penetrating the base to be exposed to the power supply unit, the second connecting member being connected to the protruding portion. A hollow portion is provided corresponding to the protrusion and the first conductive portion, and slides with the sliding of the first connecting member while accommodating the protrusion and the first conductive portion, and a second conductive portion having elasticity is provided on the top surface of the second connecting member, and the same number of holes as the conductive portion are drilled in the top surface of the second connecting member in correspondence with the position of the first conductive portion, and the first conductive portion is connected to the power supply unit and the drive unit by a first wiring via a second circuit board on which the first control unit is provided, and the second conductive portion is connected to the support unit by a second wiring.

In one embodiment, the second conductive portion further includes a first conductive material that is inserted into the hole of the second connecting member so that one end of the first conductive material protrudes from the top surface of the second connecting member, a rotatable second conductive material that is provided between the first conductive material and the first conductive portion, and a conductive elastic member that is disposed in the hole so that at least a portion of the conductive elastic member is interposed between the second conductive material and the first conductive material.

According to yet another embodiment, the fascia gun further includes a switch provided on the main body, and the first control unit controls the drive unit so that the massage can be performed in any one of a plurality of massage modes in response to a user's operation,

The modes include manual mode, face mode, stretch mode and relax mode.

In some embodiments of the present invention, the connection pins may be arranged in a row in the same direction, or may be arranged in a cross shape that intersects at a position corresponding to the center of the ring.

According to one aspect of the present invention, the support portion is provided so as to be electrically connectable to the massage head, and includes a conductive portion that can supply power from the power supply portion of the main body to the massage head by coupling the massage head to the main body, so there is no need to charge the massage head separately, and a highly convenient fascia gun with a simple configuration is provided.

If the massage head includes a heating/cooling section that has both a heating and cooling function, power is supplied from the power supply section of the main body, making it possible to heat and cool for long periods of time.

In addition, if the massage head further includes an exhaust fan, the heating and cooling effects can be achieved quickly. In particular, when switching from heating mode to cooling mode, the remaining heat can be released quickly, further improving the user experience.

Furthermore, if a configuration is adopted in which the temperature of the massage head can be controlled in multiple stages or a configuration that allows massage in multiple modes is adopted, a more convenient fascia gun can be provided.

The terms "first," "second," etc. used below are merely identification symbols for distinguishing identical or corresponding components from one another, and the identical or corresponding components are not limited by the terms "first," "second," etc., nor are they distinguished in any way as to superiority or inferiority.

In this specification, the term "bonded" refers not only to cases where the components are in direct physical contact with each other, but also includes cases where the components are in indirect contact with each other via an intermediate medium. Furthermore, the term "substantially" is used in a sense that includes measurement error.

First Embodiment
1 to 5, the fascia gun according to the first embodiment of the present invention includes a main body 2 and a massage head 1. The main body 2 has an external shape similar to a pistol, with two hollow cylindrical parts (a first cylindrical part and a second cylindrical part) each having one open end connected near their open ends.

The first cylindrical section aligned with the vibration direction of the massage head 1 mainly houses a support section for supporting the massage head 1 and connecting it to the main body, a drive section for vibrating the massage head 1 by sliding the support section, and a control section for controlling the components of the main body 2. The second cylindrical section connected to the first cylindrical section also houses a power supply section, forming a grip section 300 suitable for the user to grip the fascia gun during treatment. In the following explanation, the direction of the massage head 1 as viewed from the main body 2 may be referred to as the front side, the side opposite the front side as the rear side, the side of the grip section as the lower side, and the side opposite the grip section as the upper side.

In this embodiment, the first cylindrical portion and the second cylindrical portion are connected to each other at an obtuse angle on the underside when viewed from the front, and the main body 2 as a whole has an external shape similar to a boomerang, resembling a mirror image of the hiragana character "ku". However, the connection between the first cylindrical portion and the second cylindrical portion is not limited to this, and the two cylindrical portions may be connected to each other at a right angle, for example.

However, in this embodiment, the outer surfaces of the first and second cylindrical sections form the cover case 200 of the main body 2, and as shown in FIG. 2, the cover case 200 is composed of a case 210 on the lower front side, a case 212 on the lower back side, and a case 214 that extends from approximately the center of the upper side to the lower rear side.

A dial switch 3 is disposed on the rear side of the main body 2 in a manner that allows it to be pressed and rotated. A striped indicator bar 4 is formed of a translucent material in the top surface area of the case 214 so as to extend from the vicinity of the dial switch 3 toward the massage head 1, and a number of LEDs (not shown) that emit different colors are provided on the inner wall of the case 214 below the indicator bar 4. In this embodiment, the LEDs can emit white light as well as red and orange light.

The detailed configuration and usage of the dial switch 3 will be described later.

Next, the internal configuration of the main body 2 will be outlined with reference to Figures 4 and 5.

The grip part 300 has a built-in power supply part 310 and a battery 31 attached thereto. The battery 31 may be a normal consumable battery or a rechargeable battery. When a rechargeable battery is used, either a charging base or a connection to an external power source via a charging cable (not shown) can be selected. For example, the USB port 320 (see the right side of the paper in FIG. 6) provided on the bottom surface of the grip part 300 may be inserted into the charging base 130 shown on the left side of the paper in FIG. 6 so as to engage with the corresponding connection pin (not shown) of the charging base 130, and the charging base 130 may be connected to an external power source. When charging via a USB charging cable (not shown), the USB charging cable may be inserted into the USB port 320 to connect to an external power source. In this embodiment, the USB port is compatible with Type C, but the type of USB port may be another existing type, and of course a new type may be adopted according to technological innovation. An indicator bar 140 is provided on the side of the grip part 300 to identify the charging status by color. An example of the indicator bar 140 is shown in FIG. 7. In the example shown in the figure, the case where the remaining power is 20% is shown on the left, and the case where the battery is fully charged is shown on the right. When the remaining power is 20%, the indicator bar 140 first lights up red, and then flashes red repeatedly every 30 seconds. Each flash lasts for 3 seconds. However, if the charge reaches 0, such as if charging is not performed despite this warning, the indicator bar 140 goes out. When the battery is fully charged, the indicator bar 140 lights up white, as shown on the right side of FIG. 7.

Returning to FIG. 5, the motion motor 20 is fixedly disposed inside the connecting portion between the first and second cylindrical portions. Inside the first cylindrical portion, the moving body 11 is connected to the support portion 12 and disposed in the area in front of the motion motor 20. The support portion 12 is configured so that it can be connected to the massage head 1 by screwing. The moving body 11 is connected to the motion motor 20 via an eccentric cam 21, and when the motion motor 20 is driven, the eccentric cam 21 converts the rotational movement around the motor shaft disposed in the vertical direction of the main body 2 into a reciprocating movement in the forward and backward directions, and the moving body 11 slides back and forth, causing the massage head 1 to vibrate back and forth via the support portion 12.

The motion motor 20 and the power supply unit 310 are controlled by a control chip built into the circuit board 19. In this embodiment, the control chip on the circuit board 19 corresponds to, for example, the "first control unit" described in the claims.

In this embodiment, the circuit board 19 is attached to, for example, the front side of the moving body 11. More specifically, as shown in the partially enlarged view of FIG. 8, a groove TR is provided along the inner circumference of the front side of the moving body 11, and the disk-shaped circuit board 19 is arranged to fit into this groove TR. The wiring WR1 between the battery 31, the motion motor 20, and the circuit board 19 is covered and protected by a silicone sleeve 13, but the wire length of the wiring WR1 is designed to leave an appropriate margin according to the movement of the moving body 11 so that it is not subjected to strong tensile stress due to the movement of the moving body 11 or damaged by rubbing against other components. In this embodiment, the motion motor 20 corresponds to, for example, the "drive unit" defined in the claims, and the eccentric cam 21 corresponds to, for example, the "connecting member" defined in the claims.

Specific configuration of the massage head 1 will be described with reference to FIG. 5. The massage head 1 includes a head shell 24 that is in contact with the affected area, a heating piece 26, a thermistor 25, a connecting rod 27, and a circuit board 28. The heating piece 26 and thermistor 25 are electrically connected to the circuit board 28, which is attached to the tip surface of the connecting rod 27 on the main body 2 side in this embodiment. The connecting rod 27 is configured by forming a disk portion arranged on the head shell 24 side and a screw portion that is erected from the center of the disk portion (rear side (main body 2 side)) and has a screw groove so that they are integrated. In addition, a recess with a screw groove is provided on the front side (massage head side) of the support part 12 of the main body 2 so that a screw thread corresponding to this screw groove is formed. The massage head 1 is assembled by fitting the head shell 24 and the connecting rod 27 to each other so as to sandwich the thermistor 25 and the heating piece 26 between them. In this embodiment, the head shell 24 corresponds to, for example, the "head portion" defined in the claims, and the connecting rod 27 corresponds to, for example, the "rod portion" defined in the claims.

When using the fascia gun for massage, the user screws the connecting rod 27 into the support 12, firmly connecting the massage head 1 to the main body 2. In this embodiment, the connecting rod 27 corresponds to the "rod portion" defined in the claims, for example.

One of the features of the fascia gun according to this embodiment is that the circuit board 28 of the massage head 1 is electrically connected to the circuit board 19 of the main body 2 by screwing the connecting rod 27 and the support part 12 together, so that the massage head 1 can receive power from the power supply part 310 of the main body 2. An example of this configuration will be described with reference to FIG. 3.

As shown in FIG. 3, flick pins 120, 120, ..., 120 are arranged in a row at a predetermined interval from each other on the surface of the rear side (main body 2 side) of the circuit board 28 so as to protrude toward the rear side.

The surface of the support 12 on the main body 2 facing the connecting rod 27 is provided with conductive rings arranged at a predetermined interval in the radial direction to form a concentric circle, and is electrically connected to the circuit board 19. The interval between the conductors 110 is designed to be approximately the same as the interval between the flick pins 120. Furthermore, the center of the row of flick pins 120 and the center of the concentric circle of the conductors 110 are designed to be approximately the same by screwing the connecting rod 27 and the support 12. Therefore, when screwing the massage head 1 to the main body 2, even if the row of flick pins 120 is slightly tilted from the horizontal plane (parallel to the X-Y plane) due to wear of the thread groove of the connecting rod 27 or the thread of the support 12, the electrical connection between the massage head 1 and the main body 2 is reliably achieved. In this embodiment, the conductor 110 corresponds to the "conductive part" defined in the claims, for example.

When the massage head 1 and the main body 2 are electrically connected, the heating piece 26 and thermistor 25 are in a state in which they can be powered from the power supply unit 310 via the circuit boards 19 and 28. The heating piece 26 is attached to the inner surface of the head shell 24 so as to fit into the head shell 24, and the heating piece 26 generates heat in accordance with the user's operation of the dial switch 3, thereby heating the head shell 24. The thermistor 25 is attached to an arbitrary location on the inner wall of the head shell 24, detects the temperature of the head shell 24, and sends a detection signal to a control chip mounted on the circuit board 19. The control chip reads out a control program stored in a memory (not shown) in which a series of instructions for temperature control are written, and performs temperature control. More specifically, the detection signal from the thermistor 25 is processed, and the temperature data of the head shell 24 is acquired and used as the detected temperature. As described below, the temperature of the head shell 24 is set to multiple levels (three levels: low, medium, and high in this embodiment) so that the user can select from them, and the control chip uses the set temperature of the selected temperature level as a threshold value to compare the acquired detected temperature with the set temperature. If the detected temperature is below the set temperature, it supplies power to the heating element 26 to turn it on, and if the detected temperature reaches the set temperature, it stops supplying power to the heating element 26 to turn it off.

In this embodiment, the thermistor 25 corresponds to, for example, a "temperature sensor" as defined in the claims, and the control chip mounted on the circuit board 28 corresponds to, for example, a "second control unit" as defined in the claims.

Although the present embodiment has been described with a single massage head 1 taken up, it is of course possible to prepare multiple types of massage heads and use them interchangeably as appropriate depending on the shape of the targeted affected area, the treatment area, and the degree of stiffness. Therefore, the number of conductors 110 is designed to be equal to or greater than the number of flick pins 120 so as to accommodate the maximum anticipated number of flick pins 120. Note that while FIG. 3 shows an example of four flick pins 120 and four conductors 110, this is merely a simplification for ease of explanation, and the actual number may be less than four or more than five.

As shown in FIG. 2, for example, the dial switch 3 is disposed behind the connection between the first and second cylindrical parts in a manner that allows it to be pressed and rotated, and is configured to be switched on and off, and the numbers 5 to 9 corresponding to each massage mode are marked at predetermined intervals near the main body. In this way, the dial switch 3 not only serves as an on/off switch for the fascia gun itself when operated by the user, but also doubles as a massage mode conversion switch, achieving multi-function in a small space.

An example of how to operate the fascia gun of this embodiment using the dial switch 3 is described below with reference to Figures 9 to 12.

As shown in FIG. 9, when the switch is off (standby state), the dial is set to "5" at the position (directly above) of the indicator bar 4. A user who wishes to start using the fascia gun first rotates the dial switch 3 so that the number of the desired massage mode moves to the position of the indicator bar 4. This causes a signal indicating the selected massage mode to be sent to the control chip on the circuit board 28, which then generates a control signal to drive the motion motor 20, causing the massage head 1 to vibrate in the specified massage mode.

In this embodiment, four vibration modes are set: manual mode, face mode, stretch mode, and relaxation mode.

In manual mode, for example, as shown in FIG. 10, when the dial switch 3 is set to "6" and the dial switch 3 is rotated so that the dial "6" is directly above, the massage head 1 vibrates at a specified speed. This speed can be switched sequentially in multiple stages by briefly pressing the dial switch 3 in the direction shown by the arrow. In other words, in this embodiment, the vibration intensity can be switched in multiple stages. For example, in the first stage, the vibration is at 2100 times/min, in the second stage, 2400 times/min, in the third stage, 2700 times/min, in the fourth stage, 3000 times/min, and in the fifth stage, 3300 times/min.

The face mode is a mode designed to be suitable for massaging the face. For example, as shown in FIG. 11, when the dial is set to "7" and the dial switch 3 is rotated so that the dial "7" is directly above, the massage head 1 vibrates at a speed of, for example, 900 times per minute.

In the stretch mode, for example, as shown in FIG. 12, when the dial switch 3 is set to "8" and the dial switch 3 is rotated so that the dial "8" is directly above, the device vibrates for 7 seconds at a speed of, for example, 1200 times per minute, stops for 3 seconds, and then repeats the vibration at the same speed and stops.

The relaxation mode is a mode in which the vibration speed is gradually changed when the dial is set to "9" as shown in FIG. 13, for example. When the dial switch 3 is rotated so that the dial "9" is directly above, a predetermined vibration frequency cycle is repeated, for example, 900 vibrations/minute → increase to 1500 vibrations/minute over 7 seconds → decrease to 900 vibrations/minute over 3 seconds → increase to 2500 vibrations/minute over 7 seconds → decrease to 900 vibrations/minute over 3 seconds → increase to 1500 vibrations/minute over 7 seconds → decrease to 900 vibrations/minute over 3 seconds.

Note that the above modes are merely examples, and the present invention is not limited to these modes. It is possible to set fewer modes, or to add other modes.

When the user presses the dial switch 3 after selecting the massage mode, power is supplied from the battery 31 of the power supply unit 310 to the heating piece 26 through the control of the control chip of the circuit board 28 via the control chip of the circuit board 19, and the head shell 24 of the massage head 1 is heated. As described above, in this embodiment, the heating temperature by the heating piece 26 can be selected in three stages: low temperature, medium temperature, and high temperature. For example, each time the dial switch 3 is pressed (for example, in the direction indicated by the arrow in FIG. 2), these set temperatures change cyclically, allowing the user to select any temperature level. In order to make the selected temperature mode easily visible to the user, for example, as shown in FIG. 14, it is designed to be distinguishable by the color of the light from the LED, for example, low temperature (for example, 40° C.) is set to white, medium temperature (for example, 43° C.) to orange, and high temperature (for example, 46° C.) to red, and the user can check which temperature mode is selected just by looking at the indicator bar 4.

Second Embodiment
Next, a second embodiment of the fascia gun according to the present invention will be described with reference to the drawings. Fig. 15 is an example of a perspective view showing the main part of the main body of the fascia gun 102 according to this embodiment, in which the front half of the cover case 200 is omitted. In Fig. 15, the dial switch is also omitted.

The first feature of the fascia gun 102 of this embodiment is the wiring structure between the power supply unit 310 and the support unit 12, specifically, the relay member 50 that is interposed between the power supply unit 310 and the support unit 12 to relay the wiring between them. Also, instead of the circuit board 19 provided in the fascia gun 100 of the first embodiment, a PCB 79 is installed between the motion motor 20 and the power supply unit 310, and a control chip is incorporated in this PCB 79. In this embodiment, the PCB 79 corresponds to, for example, the "second circuit board" defined in the claims.

The relay member 50 includes a fixed portion 53 and a connecting member 51. The connecting member 51 is formed in a hollow, approximately rectangular parallelepiped shape, and is coupled to a moving body 41 that is provided in place of the moving body 11 of the first embodiment described above and is shorter in front-to-rear dimension than the moving body 11. When the moving body 41 moves in the front-to-rear direction due to the eccentric cam 21, the connecting member 51 also moves in the front-to-rear direction in conjunction with this. In this embodiment, the connecting member 51 corresponds to, for example, a "second connecting portion" as defined in the claims.

On the other hand, the fixing part 53 is fixed to the inner wall of the case 200 by a screw (not shown). The fixing part 53 has a base 531, a protruding part 529, and a conductive stripe 57. The protruding part 529 is erected so as to protrude from the side surface of the base 531 that faces the connecting member 51 toward the connecting member 51, and is housed in the hollow part HP (see FIG. 17) of the connecting member 51.

The fixed portion 53 is further provided with conductive stripes 57, the number of which corresponds to the number of wirings WR21. The conductive stripes 57 are disposed on the top surface of the protrusion 529 and housed in the hollow portion HP of the connecting member 51 together with the protrusion 529, and one end of the conductive stripes 57 penetrates the base 531 to be exposed on the side of the power supply unit 310 and connected to the wirings WR21. The conductive stripes 57 are formed of a conductive material such as copper.

The top surface of the connecting member 51 is provided with holes CV (see FIG. 17) in the same number as the conductive stripes 57, corresponding to the positions of the conductive stripes 57. Elastic beads 55 are inserted into the holes CV, electrically connected to the conductive stripes 57 on the bottom side, and exposed from the connecting member 51 on the top side to be connected to the wiring WR22. A protective material 511 is provided around the portion of the elastic beads 55 exposed from the connecting member 51, thereby fixing the elastic beads 55 to the connecting member 51. Both wirings WR21 and 22 are covered with a silicone sleeve. In this embodiment, the wirings WR21 and 22 respectively correspond to, for example, the "first wiring" and "second wiring" defined in the claims.

The structure of the elastic bead 55 will be described in more detail with reference to FIG. 17. The elastic bead 55 is made of a conductive material such as stainless steel, and has a conductor 551, a conductive spring 555, and a conductive ball 553. The conductive ball 553 is interposed between the conductive stripe 57 on the bottom side of the conductor 551, and the conductive spring 555 is arranged so that at least a part of it is interposed between the conductor 551 and the conductive stripe 57, and the elastic force of the conductive spring 555 reduces and absorbs vibrations caused by the rotation of the conductive ball 553. In this embodiment, the elastic bead 55, the conductive ball 553, and the conductive spring 555 correspond to, for example, the "second conductive part," the "second conductive material," and the "elastic member" defined in the claims, respectively.

In this way, the relay member 50 includes the conductive stripe 57 and the elastic bead 55 electrically connected to the conductive stripe 57. The conductive stripe 57 is fixed to the case 200 via the base 531. Even if the connecting member 51, together with the moving body 41, slides back and forth while accommodating the protrusion 529 and the conductive stripe 57 by the eccentric cam 21, the elastic bead 55 moves smoothly by the conductive ball 553 while maintaining the electrical connection with the conductive stripe 57. Therefore, the length of the wiring (second wiring) WR22, which expands and contracts due to the forward and backward movement of the moving body 41, can be significantly shorter than the wiring WR1 in the first embodiment. This ensures a stable electrical connection while ensuring power supply from the power supply unit 310. In this embodiment, the conductive stripe 57 corresponds to, for example, the "first conductive part" defined in the claims.

The second feature of the fascia gun 102 according to this embodiment is the electrical connection structure of the massage head. This will be explained with reference to FIG. 18.

That is, as is clear from comparison with FIG. 3, the massage head 111 connected to the fascia gun 102 of this embodiment is provided with five flick pins (15, 17) for electrically connecting with the ring-shaped conductor 110 of the main body 2, and is arranged in a cross shape rather than in a line in a specific direction. The central flick pin 17 corresponds to the center of the concentric circles of the conductor 110 and is arranged at the intersection of the cross. In addition, one of the peripheral flick pins, flick pin 15, is formed in a larger size than the other flick pins, which allows the user to easily sense the contact with the conductor 110 when attaching it, thereby improving user convenience accordingly.

The other configurations of the fascia gun 102 of this embodiment, i.e., the shape of the case 200, the power supply unit 310, the motion motor 20, the eccentric cam 21, the dial switch 3, and the operation methods thereof, as well as the use and heating methods of the massage head 111, are substantially the same as those of the fascia gun 100 of the first embodiment described above, and therefore, repeated explanations will be omitted.

Third Embodiment
Next, a third embodiment of the fascia gun according to the present invention will be described with reference to the drawings. Fig. 19 is an example of a perspective view showing the main configuration of the massage head 60 of the fascia gun 104 according to this embodiment. The configuration of the main body of the fascia gun 104 according to this embodiment is substantially the same as the fascia guns 100 and 102 of the above-mentioned embodiments. Therefore, the following description will be omitted as appropriate.

The massage head 60 shown in FIG. 19 has heating and cooling functions, and is further characterized by having an exhaust fan that promotes heat dissipation.

More specifically, the massage head 60 includes a head shell 601 that is brought into contact with the affected area of the user, a thermistor 605, a heating/cooling unit 612, a heat dissipating metal block 614, an exhaust fan 616, a circuit board 624, an internal holder 622, an external holder 638, a terminal holder 656, and a silicon ring 662. The heating/cooling unit 612 and the exhaust fan 616 are housed in the internal holder 622 together with the heat dissipating metal block 614. The internal holder 622 has a protrusion that stands upright from its bottom surface to the rear side (main body side), and the circuit board 624 has a ring shape and is attached to the bottom surface of the internal holder 622 by passing through the protrusion of the internal holder 622 at its opening.

The thermistor 605 is attached to the back side of the head shell 601, and the head shell 601 is housed in the internal holder 622. A high nut is erected on the back side of the head shell 601, and this high nut passes through the gap between the wing-shaped protrusions on the peripheral surface of the heat dissipating metal block 614 and is aligned so as to correspond to the screw holes drilled in the bottom surface of the internal holder 622 and the circuit board 624, and the high nut on the back side of the head shell 601 is screwed into the screw 628, thereby fixing it to the internal holder 622.

The head shell 601, heating and cooling unit 612, heat dissipating metal block 614, exhaust fan 616, internal holder 622 and circuit board 624 are housed in the drum portion of the external holder 638, and are fixed to the external holder 638 by aligning the high nut 652 erected on the bottom surface of the internal holder 622 with the screw hole of the external holder 638 and screwing it into the screw 654. As a result, the open front surface of the external holder 638 is sealed by the head shell 601.

The external holder 638 has a generally cylindrical threaded portion extending from the bottom surface (rear side) of the drum portion, and a terminal holder 656 is attached to the rear end of the terminal holder 656. A flick pin 220 similar to the flick pins 15, 17 and 28 of the previously described embodiment is provided on the bottom surface (rear side) of the terminal holder 656. A silicon ring 662 is attached to the circumferential surface of the threaded portion of the external holder 638, which forms a thread groove on the circumferential surface of the threaded portion to form a thread that corresponds to the thread groove on the front side (massage head side) of the support part 12 on the main body side.

In this embodiment, the head shell 601 is made of a material with excellent thermal conductivity, such as a zinc alloy, and the heat dissipating metal block 614 is also made of a material with excellent thermal conductivity, such as an aluminum alloy. The inner holder 622 and the outer holder 638 are made of a general-purpose resin, such as ABS plastic.

The circuit board 624 is connected to the flick pin 220 by wiring (not shown), and is electrically connected to the thermistor 605, the heating/cooling unit 612, and the exhaust fan 616 by wiring (not shown). The circuit board 624 receives power from the power supply unit 310 via the wiring 13 or wiring WR21 on the main body side and the conductor 110 of the support unit 12, and drives the heating/cooling unit 612 and the exhaust fan 616, and processes the detection signal output from the thermistor 605 to control the heating/cooling unit 612 and the exhaust fan 616. The circuit board 624 is also connected to the circuit board 19 on the main body side, and controls the heating/cooling unit 612 and the exhaust fan 616 based on a command signal sent from the circuit board 19. More specifically, a number of preset threshold values are stored in a memory element (not shown), and the circuit board 624 processes the detection signal from the thermistor 605 to calculate the surface temperature of the head shell 601, and by appropriately comparing it with the threshold values, the temperature of the massage head 601 can be controlled in multiple stages.

In this embodiment, the circuit board 624 corresponds to, for example, the "second control unit" defined in the claims.

In this embodiment, the heating/cooling unit 612 is constructed using a Peltier element. When the circuit board 628 is controlled to turn ON and direct current is supplied from the power supply unit 310 of the main body, for example, the face SF1 on the head shell 601 (front side) absorbs heat (cools), and the opposite face SF2 on the right side (rear side) dissipates heat (heats). The cooling face SF1 comes into contact with the head shell 601 and transmits the cooled temperature to the user's skin that is in contact with the head shell 601, while the heat generated by heating on the opposite face SF2 is transmitted to the heat dissipating metal block 614 and released.

The massage head 60 of this embodiment further includes an exhaust fan 616, which is turned ON by the control of the circuit board 628 in the cooling mode, and the heat transferred to the heat dissipating metal block 614 is discharged outside the main body of the fascia gun through multiple tacts to cool it down. This allows the heat of the heating surface SF2 to be quickly discharged, thereby improving the cooling effect. Examples of the tacts include gaps between the wing-like protrusions provided along the circumferential surface of the heat dissipating metal block 614, gaps (ring-shaped openings) provided on the circumferential surface of the drum part of the inner holder 622, and gaps (ring-shaped openings and radial openings) provided on the circumferential surface of the drum part and the (rear) bottom surface of the outer holder 638. In one embodiment, the rotation speed of the exhaust fan 616 is 4,200 to 4,500 revolutions per minute. As an example of the specific heat dissipation effect of the exhaust fan 616, for example, in an indoor temperature environment of 25°±2°, it was possible to dissipate heat down to a minimum of 8°C, and it was possible to maintain 10°C for approximately 10 minutes.

The heating and cooling unit 612 of this embodiment uses a Peltier element, so it can switch between one-side heating and one-side cooling by switching the positive and negative polarities of the supplied current. In other words, by reversing the positive and negative polarities of the direct current under the control of the circuit board 628, the SF1, which was the cooling surface until then, can be changed to a heating surface for heat dissipation, and the surface SF2, which was the heat dissipation surface until then, can be changed to a cooling surface that absorbs heat. Therefore, in the heating mode, power is supplied to the Peltier element in the opposite direction to that in the cooling mode, so that the back surface SF2 cools, while the top surface SF1 heats, and this is transmitted to the user's skin in contact with the massage head 60 via the contacting head shell 601. At this time, even if an exhaust fan 616 is included as in this embodiment, the exhaust fan 616 is not operated.

The massage head 60 of this embodiment can also be easily heated or cooled by user operation. The temperature levels for heating and cooling can be preset, and as in the above-mentioned embodiment, the user can select the desired temperature level by pressing the dial switch 3 on the main body (for example, in the direction indicated by the arrow in Figure 2).

The specific configuration of the massage head 60 of the fascia gun of this embodiment has been described with reference to Figure 19, but Figure 19 shows only one example of the specific configuration. This embodiment can be configured in various ways, such as as a massage head with a heating/cooling unit, or as a massage head with a heating/cooling unit and an exhaust fan.

(others)
In the above embodiment, the case where three temperature settings can be selected is taken up, but the present invention is not limited to this, and it is easy to design two or four or more temperature levels to be selectable. In addition, it is of course possible to set each temperature level to an arbitrary temperature.

When the user has finished the massage at the desired temperature and in the desired mode, for example as shown in Figure 9, the user can turn the dial switch 3 back to dial "5" to turn off the fascia gun.

In the above embodiment, the massage head 1, 111 having a heating function and the massage head 60 having a heating and cooling function are described as massage heads. However, when neither the heating nor the cooling function is required, massage heads of various shapes can be used according to the treatment desired by the user. Some examples of other massage heads that can be attached to the main body 2 of the above embodiment are shown in FIG. 20. (a) is U-shaped and is suitable for use on muscles such as the forearm, spine, and both sides of the Achilles tendon. (b) is spherical and is suitable for use on large muscles such as the thighs, back, and buttocks. (c) is cushioned and features a soft stimulation, and is suitable for use on muscles such as the face and shoulders. (e) is cylindrical and is suitable for pinpoint stimulation of the soles of the feet. For comparison, the (flat) massage head 1 in the above embodiment is shown again in (d).

The above describes the embodiments of the present invention with reference to the attached drawings. However, these are provided for the purpose of making the invention easier to understand, and are not intended to limit the scope of the claims of the present invention. The numbers given to the above embodiments are merely for convenience of description, and do not indicate the superiority or inferiority of the embodiments.

Those skilled in the art can realize the present invention by making various modifications without departing from the scope and spirit of the present invention. For example, features of one embodiment can be incorporated into another embodiment to obtain another embodiment. Those skilled in the art can make various modifications, equivalent substitutions, improvements, etc. in accordance with the spirit of the present invention without departing from the scope of the claims.
