Description

TECHNICAL FIELD The present invention relates to a massage machine that operates when detecting a pot.

[Prior Art] Conventionally, there has been known one that detects a pot position of a human body and massages around the pot position. As such a technique, for example, the following has been proposed. That is, (1) A pain detecting protuberance in which a light-emitting body that blinks in response to the vibration of the applicator is provided at the rear end of the body that projects from one end of the applicator that is axially reciprocally vibrated. "Acupressure tool" provided with a section (Japanese Patent Publication No. 61-10144).

(2) The function of the pot search conductor is also used for the vibrator, the pot position is detected by the buzzer notification and the meter display, and the vibrator is activated at the confirmation position to vibrate the oscillator. (Japanese Patent Publication No. 63-77035).

[Problems to be Solved by the Invention] However, in the conventional technology, the function of detecting the pot position and the function of massaging the detected pot position by the oscillator position are not linked. Therefore, even if the pot position can be accurately detected, it is extremely difficult to effectively massage the detected pot position due to a positional shift or the like during operation of the vibrator.

It is an object of the present invention to provide a massage machine position which has a simple structure and is capable of accurately massaging the acupuncture position appropriately.

[Means for Solving the Problems] The present invention, which has been made to solve the above-mentioned problems, has a treatment section formed of a conductive material and forming a pot detection electrode, and reciprocates by a drive mechanism that operates according to an external command. A vibrator that vibrates, a handle electrode that is disposed in the grip of the main body that loosely fits the vibrator, and an electric resistance value between the handle electrode and the pot detection electrode of the treatment unit of the vibrator is a predetermined resistance. The gist of a massage machine is characterized by comprising control means for outputting a command for reciprocally vibrating the vibrator to the drive mechanism for a predetermined time after the value falls below the value.

[Operation] The massage machine according to the present invention is configured so that the electric field between the pot detection electrode of the vibrator having the treatment portion formed of the conductive material and the handle electrode provided in the grip of the main body in which the vibrator is loosely fitted is provided. From when the resistance value falls below the predetermined resistance value for a predetermined time,
The control means serves to output a command for reciprocally vibrating the vibrator to the drive mechanism.

That is, if the electric resistance value between the grip electrode and the pot detection electrode decreases while the skin is being scanned by the treatment part of the oscillator while holding the grip electrode of the grip portion, it is assumed that the pot position has been reached for a predetermined time. The vibrator is reciprocally oscillated over the entire area to massage the pot position.

[Embodiment] Next, a preferred embodiment of the present invention will be described in detail with reference to the drawings. A schematic structure of a massage machine according to one embodiment of the present invention is shown in FIGS.

As shown in each of these figures, the massage machine 1 is substantially T
Heads 3 and 4, which have a V-shape, reciprocally vibrate in the axial direction and have a treatment section 2 at the tip, a drive mechanism 5 that reciprocally vibrates the heads 3 and 4, a motor 6 that supplies a driving force to the drive mechanism 5, and It is composed of a control circuit 7 for controlling this.

A plurality of protrusions 11 are provided on the skin contact surface of the treatment section 2 provided at the tip of the head 3 so as to give an appropriate stimulus when the skin is brought into direct contact with the skin. On the other hand, head 4
The skin-contacting surface of the is shaped smooth so that it can be massaged either from the skin or from above the clothing. Both of these treatment parts 2 are made of a conductive synthetic resin containing vinyl chloride, carbon, or the like. The heads 3 and 4 are respectively connected to the swing shafts 12 and 13 and swing integrally. Swing shaft 12,13
Are connected to the drive mechanism 5. In addition, the swing shaft 12,13
The connection between the heads 3 and 4 is covered with a head cover 1a.

The drive mechanism 5 is housed inside the housing 20.
The worm gear 21 supported by the main shaft of the motor 6 meshes with the wheel gear 22. A bush 24 is rotatably attached to the pin 23 erected on the side surface of the wheel gear 22. The bush 24 is loosely fitted in a rectangular space formed on the side surface of the lever 25. Therefore, as the motor 6 rotates, the worm gear 21 and the wheel gear
When the 22 rotates, the lever 25 is pushed by the bush 24 via the pin 23, and the lever 25 reciprocates.

The lever 25 is provided with oscillating shafts 12 and 13 on both end faces in the longitudinal direction, and heads 3 and 4 are attached to the tip ends thereof by being pressed and biased by coil springs 26 and 27.

A control circuit 7 for driving and controlling the motor 6 is provided inside the handle portion 31. The pot detection terminal 7 a, which is one terminal of the control circuit 7, is connected to the conductive case 6 a of the motor 6 via the lead wire 32. The conductive treatment portions 2, 4a of the heads 3, 4 are electrically connected to the motor case 6a via the swing shafts 12, 13, the housing 20, and the motor mounting bracket 6b. On the other hand, the handle terminal 7b which is the other terminal of the control circuit 7
Is connected to a handle electrode 33 provided on the surface of the handle portion 31 via a lead wire 34.

When these treatment parts 2 and 4a are scanned along the skin of the human body, the control circuit 7 detects the pot position of the human body due to the change in the electric resistance value between the treatment parts 2 and 4a and the handle electrode 33. .

The massage machine 1 is disposed on the side surface of the grip portion 31 and has a head.
The main switch 35 that slides the knob 35a in the direction of arrow A to switch the vibration states of 3 and 4 between three levels of "OFF", "weak", and "strong", and the knob 36a is provided on the bottom surface of the grip 31. Slide in the direction of arrow B to change the drive status of the heads 3 and 4 to "Automatic (AUT
O) and "manual" (MANUAL), and also has an AM switch 36 that adjusts the pot detection sensitivity by rotating knob 36a in the direction of arrow C. Power is supplied from power cable 37. In response, move the heads 3 and 4 with arrow D
Reciprocating vibration in the direction.

Next, the configuration of the control circuit 7 will be described with reference to FIG. The control circuit 7 rectifies and smoothes the supplied electric power (AC 100 [V]) to drive the motor 6, and a drive circuit 41 that is connected in parallel with the drive circuit 41 to reduce the power supply voltage supplied. A comparison circuit 43 for measuring the electric resistance value between the pot detection terminal 72a and the grip terminal 7b, and a timer circuit 4 which operates for a predetermined time after the comparison circuit 43 outputs a pulse signal.
4, a photocoupler 45 that transmits a pulse signal from the comparison circuit 43 to the timer circuit 44, a light emitting diode 46 that emits light when the timer circuit 44 operates, and each circuit 41 while receiving light from the light emitting diode, Phototriacs 47, 48 for energizing 42, 43, 44 are provided. Where the main switch 3
When the knob of 5 is turned on from the “off” position 35b to the “weak” position 35c, the supplied power is radially rectified, so that the motor 6
The rotation speed of is relatively slow. On the other hand, when the power is supplied to the "strong" position 35d, the supplied power is full-wave rectified, so that the rotation speed of the motor 6 becomes relatively high. Also, by operating the AM switch 36, the contact 36b opens and closes automatically (AUT
O) and manual (MANUAL) can be switched, and the pot detection sensitivity can be adjusted by changing the resistance value of the variable resistor 36c.

Next, the operation of the massage machine 1 having such a configuration will be described with reference to FIGS.

When setting {AUTO} Set the AM switch 36 to the automatic (AUTO) position,
After setting the pot detection sensitivity to the specified sensitivity, the main switch 35
To “weak” or “strong”. Next, the holding portion 31 is held by one hand, and one of the treatment portions 2 and 4a of the heads 3 and 4 is brought into contact with the human body to scan the pot position. For example, a case where the treatment section 2 is brought into contact with a human body will be described. When the treatment section 2 reaches the pot position, the electrical resistance value between the treatment section 2 and the handle electrode 33, that is, the pot detection terminal 7a and the handle terminal 7b decreases. Then, the comparison circuit 43 outputs a pulse signal. This pulse signal is transmitted as an optical signal from the light emitting diode 45a of the photocoupler 45 to the phototransistor 45b. As a result, the timer circuit 44 operates, and the light emitting diode 46 emits light for a time determined according to the capacitance of the capacitor 44a. This light is received by the photo triac 47, and the photo triac 48 is switched from the cutoff state to the conductive state. Then, half-wave rectification or full-wave rectification is performed according to the setting of the main switch 35, and the motor 6 rotates. Along with this, the drive mechanism 5 and the swing shafts 12 and 13
The heads 3 and 4 start reciprocating vibration through, and in this case,
When the treatment unit 2 in contact with the human body determines the pot position, the timer circuit
Massage continuously for 44 hours.

When set to {MANUAL} In this case, contact 36b closes, so main switch 3
One of the treatment units 2 and 4a in contact with the human body massages the skin of the human body in contact with the strength corresponding to the operation of 5.

In this embodiment, the heads 3 and 4 correspond to the vibrator, the handle electrode 33 corresponds to the handle electrode, and the control circuit 7 corresponds to the control means.

As described above, according to this embodiment, the position of the pot can be accurately detected and the massage can be performed immediately.

Further, since the treatment section 2 reciprocates for a predetermined time from when the treatment section 2 reaches the pot position, even if the treatment section 2 once leaves the pot position due to vibration, if the treatment section 2 comes into contact with the skin again,
You can continue to massage.

Further, the A-M changeover switch 36 can arbitrarily set the pot detection sensitivity. Therefore, even when the skin is moist due to sweating or the like, or when the skin is dry, it is possible to adjust to the appropriate pot detection sensitivity in any state.

Further, by operating the AM switch 36, when A (automatic) is set, massage can be started at the same time as the pot is detected, while when M (manual) is set, normal massage is performed over a wide range from above the clothes. You can massage like a machine, so you can quickly eliminate muscle fatigue.

Further, since the speed of the reciprocating vibration of the heads 3 and 4 can be changed in two steps by switching the main switch 35, the strength of massage can be switched between "strong" and "weak".

In addition, since the heads 3 and 4 reciprocally vibrate at the same time as the detection of the pot and start the massage, a dedicated pot detection device such as a buzzer or a lamp is not required, so that the configuration can be simplified.

In this embodiment, the reciprocating vibration type massage machine 1 in which the heads 3 and 4 vibrate reciprocally has been described. But,
For example, a so-called rotary vibration type massager that massages a treatment part by rotating a head using unbalanced weights may be applied with an automatic operation function that is activated at the time of detecting a pot having the same configuration as that of the present embodiment. it can.

[Effect of the Invention] As described in detail above, according to the massage machine of the present invention,
With a simple structure, it has an excellent effect that the pot position can be massaged accurately and appropriately.

Further, since the vibrator vibrates back and forth for a predetermined time after reaching the pot position, even if the treatment section leaves the pot position due to the vibration, it is possible to continuously massage the pot position and its surrounding parts. it can.
