Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electric massager device of the type in which a vibrating head is pressed against a user's affected area and the user's affected area is massaged by the vibrating head.

[0002]

[Prior art and its problems]

 FIG. 6 shows a conventional electric rice cooker. This paddle has a vibrating head 1 that is pressed against the affected area of the user, and the vibrating head 1 is attached to a rod 2. The rod 2 is installed in the casing 3 and is guided so as to be linearly movable back and forth. Further, this safety device is of a magnet type and has a magnet 4 and a movable iron core 5, and the movable iron core 5 is engaged with the rod 2. Further, the vibrating head 1 and the rod 2 are elastically biased by the spring 6, and the magnet 4 is connected to the switch 7 and the AC power source.

Therefore, when the switch 7 is manually operated and closed, AC power having a frequency of 50 Hz or 60 HZ is supplied to the magnet 4, and the magnet 7 is magnetized twice for each cycle of the AC power waveform. 4 is excited and the iron core 5 is attracted. Therefore, when the AC power has a frequency of 50 HZ, the iron core 5 is sucked with a cycle number of 100 / sec, and when the AC power has a frequency of 60 HZ, the iron core 5 is sucked with a cycle number of 120 / sec. . When the AC power is rectified by the rectifier and supplied to the magnet 4, the magnet 4 is excited once for each cycle of the waveform of the AC power, and the iron core 5 is attracted. Therefore, the iron core 5 is attracted with a cycle number of 50 / sec when the AC power has a frequency of 50 HZ, and the iron core 5 is attracted with a cycle number of 60 / sec when the AC power has a frequency of 60 HZ.

Each time the movable iron core 5 is sucked, the tip of the movable iron core 5 draws an arc and swings, and the rod 2 and the vibrating head 1 are pushed and propelled by the movable iron core 5. Then, the vibrating head 1, the rod 2 and the movable iron core 5 are pushed back by the spring 6. This is repeated at high speed, and the vibrating head 1 reciprocates linearly at high speed to vibrate. The frequency corresponds to the number of suction cycles of the movable iron core 5. Therefore, the vibrating head 1 can be vibrated at a frequency of 100 / sec or 50 / sec when the AC power has a frequency of 50HZ, and 120 / sec or 60 / sec when the AC power has a frequency of 60HZ. The vibrating head 1 can be vibrated by the frequency. Therefore, the vibrating head 1 can be pressed against the affected part of the user, and the vibrating head 1 can massage the affected part of the user.

By the way, in the case of this paddle, the movable iron core 5 is attracted to the magnet 4, the movable iron core 5 is pushed back by the spring 6, and this is repeated at high speed. Therefore, there is a problem in that the impact of the movable iron core 5 and the magnet 4 causes large noise and vibration of the housing 3.

Further, it is the tip of the movable iron core 5 that draws a circular arc that engages with the rod 2 of this paddle and pushes and pushes it. Therefore, not only the rod 2 is pushed and propelled by the movable iron core 5, but also the rod 2 is rubbed by the movable iron core 5, causing a so-called break between the movable iron core 5 and the rod 2, so that the movable iron core 5 and the rod 2 are separated from each other. There is also the problem of early wear and damage. Along with this, a radial load acts on the rod 2, causing a crack between the rod 2 and the housing 3, which may be worn and damaged early.

In addition to the above, regarding the frequency of the vibrating head 1, it is not possible to say unequivocally what frequency is effective. It is determined by the symptoms of the user. Therefore, it is preferable that the vibration frequency of the vibrating head 1 is changed and selected according to the symptoms of the user. However, even if the vibrating head 1 can be vibrated at a frequency of 100 / sec or 50 / sec with AC power having a frequency of 50 HZ, the vibrating head 1 is vibrated at a frequency other than this with this annunciator. The vibration frequency of the vibrating head 1 is limited to two kinds of frequencies. Further, even with AC power having a frequency of 60 HZ, the obtained frequency is 120 / sec or 60 / sec, and it is the same as being limited to two types of frequencies. Therefore, it is required to vibrate the vibrating head 1 not only with two types of frequencies but also with various types of frequencies.

[The purpose of the device]

 The present invention solves the above-mentioned conventional problems in an electric stove in which the vibrating head is pressed against the affected area of the user and the affected area of the user is massaged by the vibrating head. The purpose of this is to prevent damage to the parts due to the dust, and to vibrate the vibrating head at various frequencies.

[0009]

[Constitution of device]

 According to this invention, a DC or AC motor is provided in the electric stove, and the motor shaft of the DC or AC motor and the vibrating head are transmission-coupled by a conversion mechanism such as a cam mechanism, and the rotation of the motor shaft is controlled by the vibrating head. Converted to reciprocating linear movement.

Further, according to the present invention, the rotation speed of the DC motor is controlled, changed and selected by the variable resistor. The frequency converter may be selected by changing the rotation speed of the AC motor.

[0011]

[Explanation of Examples]

 An embodiment of this invention will be described below. FIG. 1 shows an embodiment of this invention. This hammer is a modification of the hammer shown in FIG. 6 and has a vibrating head 1 and a rod 2. The vibrating head 1 is similar to that of FIG. 6 and is mounted on a rod 2, which is mounted in a housing 3 and is guided so as to be reciprocally movable.

This alarm device has a DC motor 8 for vibrating the vibrating head 1. The DC motor 8 is a servo motor, which is generally used, has a variable resistor 9, is attached to the casing 3, and is connected to the switch 10 and a DC power source. The variable resistor 9 is for changing and selecting the number of rotations of the DC motor 8, has an operating knob 11, is attached to the casing 3, and is connected to the DC motor 8. Therefore, the current can be controlled by the operation knob 11 of the variable resistor 9, and the rotation speed of the DC motor 8 can be arbitrarily changed and selected. It is well known that the servo motor has high controllability, and it is preferable.

Further, this paddle has a cam mechanism 12 for transmitting the output of the DC motor 8. The cam mechanism 12 is composed of a cam ring 13 and a cam follower 14. The cam follower 14 is a round piston and has a vibration. It is arranged on the same axis as the head 1, is housed in a casing 3, is guided so as to be capable of reciprocating linear movement, and is connected to a rod 2 of the vibrating head 1. The vibrating head 1 and the rod 2 are elastically biased by the spring 6. The cam ring 13 has a cylindrical shape, is arranged below the cam follower 14, and is attached and fixed to the motor shaft 15 of the DC motor 8. The motor shaft 15 extends in a direction perpendicular to the vibrating head 1, the rod 2 and the cam follower 14.

Further, as shown in FIGS. 3, 4 and 5, a recess 16 is provided on the lower surface of the cam follower 14, a widthwise groove 17 is formed on the bottom surface thereof, and an eccentric pin 18 is provided on the end surface of the cam ring 13. The tip of the cam ring 13 is housed in the recess 16, and the eccentric pin 18 is inserted in the groove 17 in the width direction. As a result, the motor shaft 15 of the DC motor 8 and the vibrating head 1 are transmission-coupled. Therefore, as will be described later, the rotation of the motor shaft 15 is converted into the reciprocating linear movement of the vibrating head 1.

When the switch 10 is manually operated to close the switch, the motor shaft 15 of the DC motor 8 rotates around its axis, and the cam ring 13 in the recess 16 of the cam follower 14 is operated. Rotates integrally with the motor shaft 15. Along with that, the eccentric pin 18 of the cam ring 13 slides along the groove 17 in the width direction of the cam follower 14, and the eccentric pin 18 pushes the cam follower 14 to propel it and linearly move it back and forth. Its amplitude is twice the eccentric distance of the eccentric pin 18.

Therefore, the vibrating head 1 and the rod 2 reciprocate linearly integrally with the cam follower 14. Therefore, the rotation of the motor shaft 15 is converted into the reciprocating linear movement of the vibrating head 1. The vibrating head advances toward the position of FIG. 1 and retracts toward the position of FIG. This is repeated at high speed, and the vibrating head 1 moves back and forth linearly at high speed to vibrate. Therefore, the vibrating head 1 can be pressed against the affected area of the user, and the affected area of the user can be massaged by the vibrating head 1.

Therefore, in the case of this hammer, the problem of the impact of the movable iron core of the magnet type hammer and the magnet does not occur. The cam mechanism 12 transmission-couples the motor shaft 15 of the DC motor 8 and the vibrating head 1, and only the rotation of the motor shaft 15 is converted into the reciprocating linear movement of the vibrating head 1, which causes a large noise and vibration of the casing 3. Does not occur. Moreover, the cam follower 14 can be pushed and propelled by the eccentric pin 18 of the cam ring 13 to smoothly and linearly move the cam follower 14 and the vibrating head 1 back and forth, and there is no problem that parts are damaged due to dust.

Further, the DC motor 8 of this safety device can be selected by changing the rotation speed of the DC motor 8 with the variable resistor 9. Therefore, the vibration frequency of the vibrating head 1 can be changed and selected according to the condition of the user, and the vibrating head 1 can be vibrated at various frequencies. Similar to the above-described magnet type steam generator, the vibrating head 1 can be vibrated at a frequency of 100 / sec or 120 / sec. It is also possible to vibrate the vibrating head 1 at a higher frequency. The vibrating head 1 can be vibrated at a frequency of 50 / sec or 60 / sec, and the vibrating head 1 can be vibrated at a frequency of higher or lower. Therefore, the user's affected area can be effectively massaged regardless of any symptoms.

In this embodiment, an AC motor may be used instead of the DC motor 8. If the frequency converter is connected to the AC motor instead of the variable resistor 9, the frequency converter can be used to change the rotational speed of the AC motor for selection. Therefore, the vibrating head 1 can be vibrated with various frequencies. When the AC motor of the servo motor is used, high control performance can be obtained, and it is preferable to use the same as the DC motor.

It is also conceivable to use another type of conversion mechanism in place of the cam mechanism 12.

[0021]

[Effect of device]

 As described above, according to the present invention, the motor shaft 15 of the DC or AC motor 8 and the vibrating head 1 are transmission-coupled by the conversion mechanism such as the cam mechanism 12, so that the rotation of the motor shaft 15 is rotated. However, no large noise and vibration of the casing 3 occur. In addition, the vibrating head 1 can be smoothly reciprocated and linearly moved, and there is no problem that parts are damaged due to the dust. Furthermore, the variable resistor 9 or the frequency converter can be used to change the rotational speed of the DC or AC motor 8 for selection. Therefore, the vibration frequency of the vibrating head 1 can be changed and selected according to the symptoms of the user, and the vibrating head 1 can be vibrated at various frequencies. Therefore, whatever the symptom is, the affected part of the user can be effectively massaged, and the intended purpose can be achieved.
