Description

The present invention belongs to the technical field of massage and fitness equipment, and more particularly to a fascia gun with heating function.

In recent years, fascial massage has attracted attention as a massage method for relieving body stiffness. By performing a massage treatment targeting the thin fascia that covers the muscles of a person, the adhesion between the fascia and the muscle or between the fascias is removed and the original elastic state is restored. By restoring the fascia, this treatment was developed to eliminate stiffness and pain and allow the joints to move smoothly.

There is a fascia gun as a device for such a fascia massage, which incorporates a dedicated high-speed motor and is linked to the massage head, which is the "head of the gun", to generate high-frequency vibrations and penetrate deep into the muscles. By acting, it aims to play a role such as relieving local tissue tension, alleviating pain, and promoting blood circulation. Some of these fascia guns have a massage head equipped with a heating mechanism in order to enhance the massage effect.

However, in the conventional fascia gun equipped with a heating massage head, it was necessary to install a battery in the massage head to supply power to the heating mechanism separately from the battery on the main body side. There was a limit to the available battery capacity, and the power supply time was very short. Therefore, it is necessary to charge the massage head separately, which is inferior in terms of convenience.

In this embodiment, the first cylindrical portion and the second cylindrical portion are connected to each other so as to form an obtuse angle on the lower side when viewed from the front, and the main body 2 as a whole is a mirror-reversal of the hiragana character "ku". It has an external shape similar to that of a boomerang. However, the connection mode between the first cylindrical portion and the second cylindrical portion is not limited to this, and the two cylindrical portions may be connected so as to form a right angle with each other, for example.

However, in this embodiment, the outer surfaces of the first cylindrical portion and the second cylindrical portion constitute a cover case 200 of the main body 2, and the cover case 200 is, as shown in FIG. , a case 212 on the lower side of the rear surface, and a case 214 extending from approximately the center of the upper side to the lower side of the rear side.

A dial switch 3 is arranged on the rear side of the main body 2 in a depressible and rotatable manner. A stripe-shaped indicator bar 4 is formed of translucent material on the top surface region of the case 214 so as to extend from the vicinity of the dial switch 3 toward the massage head 1 side, and the inner wall of the case 214 below the indicator bar 4 emits light. A plurality of LEDs (not shown) of different colors are provided. In this embodiment, the LED can emit red and orange light in addition to white light.
The detailed configuration and usage of the dial switch 3 will be described later.
Next, an outline of the internal configuration of the main body 2 will be described with reference to FIGS. 4 and 5. FIG.

A power supply unit 310 is built in the grip portion 300, and a battery 31 is attached thereto. Battery 31 may be a normal consumable type battery or a rechargeable battery. When using a rechargeable battery, either a charging base or connecting to an external power supply via a charging cable (not shown) can be selected. For example, on the charging base 130 shown on the left side of the paper surface of FIG. 6, the USB port 320 (see the right side of the paper surface of FIG. 6) provided on the bottom surface of the grip part 300 is fitted to the corresponding connection pin (not shown) of the charging base 130. and connect the charging base 130 to an external power source.

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. In the example shown in the figure, the case where the remaining power level is 20% is shown on the left side, and the case of full charge is shown on the right side. When the remaining power reaches 20%, the indicator bar 140 first turns on red and repeats the red flash every 30 seconds. Each flash lasts 3 seconds each time. However, if charging is not performed in spite of this warning, the light turns off when the charge reaches zero. When the battery is fully charged, the indicator bar 140 lights up in white as shown on the right side of FIG.

Returning to FIG. 5, a motion motor 20 is fixedly installed inside the connecting portion between the first cylindrical portion and the second cylindrical portion. A movable body 11 is coupled to a support portion 12 and disposed in front of the motion motor 20 inside the first cylindrical portion. The support 12 is configured to be connectable to the massage head 1 by screwing. The moving body 11 is connected to a motion motor 20 via an eccentric cam 21. When the motion motor 20 is driven, the eccentric cam 21 rotates the moving body 11 about a motor shaft arranged in the vertical direction of the main body 2 in the front-rear direction. The moving body 11 slides back and forth, which is converted into repetitive movement, and the massage head 1 vibrates back and forth via the support portion 12 .

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

In this embodiment, the circuit board 19 is attached, for example, to the front side portion 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 portion of the moving body 11, and a disk-shaped circuit board is fitted to the groove TR. 19 are arranged. The wiring WR1 between the battery 31, the motion motor 20 and the circuit board 19 is covered and protected by the silicon sleeve 13, but it is subject to strong tensile stress due to the movement of the moving body 11 and rubbing against other components. The wire length of the wiring WR1 is designed so that an appropriate margin remains according to the movement of the moving body 11 so as not to damage the wiring WR1. In the present embodiment, the motion motor 20 corresponds to, for example, a "driving section" defined in claims, and the eccentric cam 21 corresponds to, for example, a "connecting member" defined in claims.

A specific configuration of the massage head 1 will be described with reference to FIG. The massage head 1 includes a head shell 24 that contacts the affected area, a heating piece 26, a thermistor 25, a connecting rod 27, and a circuit board . The heat-generating piece 26 and the thermistor 25 are electrically connected to a circuit board 28, and the circuit board 28 is attached to the end surface of the connecting rod 27 on the main body 2 side in this embodiment. The connecting rod 27 is formed so that a disk portion arranged on the side of the head shell 24 and a screw portion with a screw groove provided upright from the center (rear side (main body 2 side)) of the disk portion are integrated. formed and configured. In addition, the front side (massage head side) of the support portion 12 of the main body 2 is provided with a recess in which a thread groove is formed so that a thread corresponding to the thread groove is formed. The massage head 1 is assembled by fitting the head shell 24 and the connecting rod 27 together with the thermistor 25 and the heating element 26 interposed therebetween. 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 massaging with a fascia gun, the connecting rod 27 is screwed into the support portion 12 by the user, so that the massage head 1 is firmly connected to the main body 2 . The connecting rod 27 corresponds to, for example, the "rod portion" defined in the claims in this embodiment.

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 portion 12 together. Therefore, the massage head 1 is configured to receive power from the power supply section 310 of the main body 2 . An example of this configuration will be described with reference to FIG.

As shown in FIG. 3, flick pins 120, 120, . are arranged as follows.
On the surface of the supporting portion 12 on the side of the main body 2 facing the connecting rod 27 , conductive rings arranged radially with a predetermined interval so as to form concentric circles are provided and electrically connected to the circuit board 19 . It is The spacing of the conductors 110 is designed to approximately match the spacing of the flick pins 120 . Further, the center of the row of flick pins 120 and the center of the concentric circle of conductor 110 are designed to substantially coincide with each other by screwing connecting rod 27 and support portion 12 together. Therefore, when the massage head 1 is screwed into the main body 2, the rows of the flick pins 120 may be slightly displaced (parallel to the XY plane) due to abrasion of the thread grooves of the connecting rod 27 and the threads of the support portion 12. ) The electrical connection between the massage head 1 and the main body 2 is reliably established even if the massage head 1 is tilted away from the horizontal plane. In this embodiment, the conductor 110 corresponds to, for example, a "conductive portion" defined in the claims.

When the massage head 1 and the main body 2 are electrically connected, the heating element 26 and the thermistor 25 are ready for power supply 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 according to the operation of the dial switch 3 by the user, thereby heating the head shell 24 . A thermistor 25 is attached at an arbitrary position on the inner wall of the head shell 24 to detect the temperature of the head shell 24 and send a detection signal to the control chip mounted on the circuit board 19 . The control chip performs temperature control by reading out a control program containing a series of instructions for temperature control stored in a memory (not shown). 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 detection temperature. As will be described later, the temperature of the head shell 24 is set in a plurality of stages (three stages of low temperature, medium temperature, and high temperature in this embodiment) so that the user can select the temperature. The control chip compares the acquired detected temperature with the set temperature, and if the detected temperature is lower than the set temperature, it supplies power to the heating element 26 to turn it on, and when the detected temperature reaches the set temperature, the heating element Remove power to 26 and turn it off.
In this embodiment, the heating element 26 corresponds to, for example, the "heating part" defined in the claims, and the thermistor 25 corresponds to, for example, the "temperature sensor" defined in the claims, and is mounted on the circuit board 28. The control chip corresponds to, for example, the "second control section" defined in the claims.

Regarding this embodiment, a single massage head 1 has been taken up and explained, but a plurality of types of massage heads are prepared according to the target shape of the affected area, the treatment range, the degree of stiffness, etc., and are used by exchanging them as appropriate. Of course you can. Therefore, the number of conductors 110 is designed to be greater than or equal to the number of flick pins 120 so as to accommodate the maximum number of flick pins 120 assumed. Although an example of four flick pins 120 and four conductors 110 is drawn in FIG. 3, this is merely a simplification for ease of explanation, and the actual number may be less than four. It may be 5 or more.

The dial switch 3, for example, as shown in FIG. 2, is arranged in a depressible and rotatable manner on the rear side of the connecting portion of the first cylindrical portion and the second cylindrical portion, and can be switched on/off. , and numerals 5 to 9 corresponding to each massage mode are marked at predetermined intervals near the main body. As a result, the dial switch 3 not only constitutes an on/off switch for the fascia gun itself, but also serves as a massage mode conversion switch, realizing space-saving multi-function. there is
An example of a method of operating the fascia gun of this embodiment using the dial switch 3 will be described below with reference to FIGS. 9 to 12. FIG.

As shown in FIG. 9, in the switch-off state (standby state), the dial "5" is set at the position (directly above) of the indicator bar 4. As shown in FIG. A user who intends to start using the fascia gun first turns the dial switch 3 so that the desired massage mode number moves to the position of the indicator bar 4 . A signal instructing the selected massage mode is thereby sent to the control chip on the circuit board 28, and the control chip generates a control signal to drive the motion motor 20, causing the massage head 1 to vibrate in the designated massage mode. .

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

As shown in FIG. 10, for example, the manual mode is set to dial "6", and when the dial switch 3 is rotated so that the dial "6" is directly upward, the massage head 1 vibrates at a predetermined speed. This speed is switched sequentially in a plurality of steps by briefly pressing the dial switch 3 in the direction indicated by the arrow. That is, in this embodiment, it is possible to switch the vibration intensity in a plurality of steps. For example, the first stage is 2100 times/minute, the second stage is 2400 times/minute, the third stage is 2700 times/minute, the fourth stage is 3000 times/minute, and the fifth stage is 3300 times/minute. to vibrate.

The face mode is a mode designed to be suitable for massaging the face. For example, as shown in FIG. is rotated, the massage head 1 vibrates at a speed of, for example, 900 times/minute.

The stretch mode is, for example, set to dial "8" as shown in FIG. It is a mode that stops for 3 seconds and then repeats vibration at the same speed→stop.

The relax mode is, for example, set to dial "9" as shown in FIG. 13, and is a mode in which the speed of vibration is gradually changed. 900 times/minute → Increase to 1500 times/minute over 7 seconds → Decrease to 900 times/minute over 3 seconds → Increase to 2500 times/minute over 7 seconds → Decrease to 900 times/minute over 3 seconds → 7 A predetermined frequency cycle is repeated such as rising to 1500 beats/minute in seconds → falling to 900 beats/minute in 3 seconds.

Note that the above modes are merely examples, and the present invention is not limited to these modes, and it is of course 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 element 26 under the control of the control chip of the circuit board 28 via the control chip of the circuit board 19. As a result, the head shell 24 of the massage head 1 is heated. As described above, in the present embodiment, the heating temperature of the heating piece 26 can be selected from three levels of low temperature, medium temperature, and high temperature. By cyclically changing the set temperature, the user can select an arbitrary temperature level. The selected temperature mode is designed to be distinguished by the color of the light from the LED, for example, as shown in FIG. 14, so that the selected temperature mode can be easily recognized by the user. , medium temperature (eg 43°C) is set in orange, high temperature (eg 46°C) is set in red, and the user can confirm which temperature mode is selected simply by looking at the indicator bar 4. can.

2nd Embodiment Next, it demonstrates, referring drawings for 2nd Embodiment of the fascia cancer which concerns on this invention. FIG. 15 is an example of a perspective view showing the essential parts of the main body of the fascia gun 102 according to this embodiment, omitting the front half of the cover case 200 . Dial switches are also omitted in FIG.

A first characteristic point of the fascia gun 102 of this embodiment is the wiring structure between the power supply section 310 and the support section 12. Specifically, between the power supply section 310 and the support section 12, these The point is that a relay member 50 is interposed for relaying wiring between each other. Also, instead of the circuit board 19 included in the fascia gun 100 of the first embodiment, a PCB 79 is installed between the motion motor 20 and the power supply section 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.

Relay member 50 includes a fixing portion 53 and a connecting member 51 . The connecting member 51 is formed in the shape of a hollow rectangular parallelepiped so as to be connected to a moving body 41 which is shorter in front and rear than the moving body 11 and which is provided in place of the moving body 11 of the first embodiment described above. combined. When the eccentric cam 21 moves the moving body 41 in the front-rear direction, the connecting member 51 also moves in the front-rear direction in conjunction with this movement. In this embodiment, the connecting member 51 corresponds to, for example, the "second connecting portion" defined in the claims.

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

The fixed portion 53 is further provided with conductive stripes 57 in a number corresponding to the number of the wirings WR21. The conductive stripe 57 is arranged on the top surface of the protrusion 529 and accommodated in the hollow portion HP of the connecting member 51 together with the protrusion 529. One end of the conductive stripe 57 penetrates through the base 531 and is exposed on the power supply unit 310 side. , are connected to the wiring WR21. Conductive stripes 57 are formed of a conductive material such as copper, for example.

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

A more detailed configuration of the elastic bead 55 will be described with reference to FIG. 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 conductor 551 and the conductive stripe 57 on the bottom side of the conductor 551, and the conductive spring 555 is arranged so that at least a portion thereof is interposed between the conductor 551 and the conductive stripe 57, and its elasticity Vibration due to rotation of the conductive ball 553 is alleviated and absorbed by the force. In this embodiment, the elastic beads 55, the conductive balls 553, and the conductive springs 555 correspond to, for example, the "second conductive portion", the "second conductive material", and the "elastic member" defined in the claims, respectively.

Thus, the relay member 50 includes the conductive stripe 57 and the elastic bead 55 electrically connected to the conductive stripe 57, and the conductive stripe 57 is fixed to the case 200 via the base 531, Even if the connecting member 51 slides back and forth together with the movable body 41 by the eccentric cam 21 while accommodating the projecting portion 529 and the conductive stripe 57 , the elastic beads 55 are prevented from moving while maintaining the electrical connection with the conductive stripe 57 . Since the conductive balls 553 move smoothly, the length of the wiring (second wiring) WR22 that expands and contracts due to the back-and-forth movement of the moving body 41 can be significantly shorter than the wiring WR1 in the first embodiment. This makes it possible to ensure 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 portion" defined in the claims.

A second feature of the fascia gun 102 according to this embodiment is the electrical connection structure of the massage head. This point will be described with reference to FIG.
3, the massage head 111 connected to the fascia gun 102 of this embodiment has a flick pin (15 , 17) are provided and arranged not in a line in a predetermined direction but in a cross shape. 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 crosses. In addition, one flick pin 15 among the flick pins in the periphery is formed in a larger size than the other flick pins, so that the user can easily sense contact with the conductor 110 during installation. The user's convenience is improved accordingly.

Other configurations of the fascia gun 102 of the present embodiment, that is, the shape of the case 200, the power supply unit 310, the motion motor 20, the eccentric cam 21, the dial switch 3, their operation method, and the usage method of the massage head 111 and The heating method and the like are substantially the same as those of the fascia gun 100 of the first embodiment described above, and therefore redundant description will be omitted.

Others In the description of the above embodiment, the case where the set temperature can be selected from three stages was taken up, but of course the present invention is not limited to this, and it is easy to set and select four or more temperature levels even with two stages. is. Also, the temperature in each stage can be set to any desired temperature.
