Abstract

PURPOSE:To widen the therapeutic range without increasing the number of solenoids by providing two therapeutic elements subjected to reciprocating motion by one solenoid. CONSTITUTION:This massage machine is provided with a hand holding part and a head part, and a solenoid 4 is provided in the head part 2 so that therapeutic elements 12, 18 attached to a plunger 9 execute a reciprocating motion in a state exposed from the head part 2. Also, two therapeutic elements 12, 18 subjected to reciprocating motion by one piece of solenoid 4 are provided. When a switch of the hand holding part is turned on, a solenoid driving circuit is operated and an output voltage is generated in a prescribed period, and when it is applied to an exciting coil 7, an end face 9c of a movable iron core 9a is attracted to the attracting face 6a of a fixed iron core 6 by overcoming spring force of a second reset spring, and the therapeutic element 12 protrudes and presses the shoulder and the waist. In this case, a second therapeutic element 18 moves to an opposite side to the therapeutic element 12. Also, when the application to the exciting coil 7 is stopped, a second therapeutic element 18 protrudes and presses the shoulder and the waist by spring force of a second reset spring, and the therapeutic element 12 moves to an opposite side of a second therapeutic element 18.

In order to solve the above problems, a tapping massage machine according to claim 1 has a hand-held portion and a head portion, and a treatment element attached to a plunger is exposed from the head portion. In a beating massage machine in which a solenoid is arranged in the head portion so as to reciprocate in a state,
Two treatment elements are provided that can be reciprocally moved by one solenoid.

Further, in the pounding massager according to claim 2, one of the massagers according to claim 1 is attached to a plunger, and the other is attached to a movable member which is reciprocally moved in the opposite direction by the plunger. It is configured as follows.

[0008]

According to the structure of claim 1, since the two treatment elements reciprocated by one solenoid are provided,
The treatment range is widened without increasing the number of solenoids.

According to the configuration of claim 2, in addition to the operation of claim 1, the pressing of the two treatment elements is performed alternately.

The tapping massage machine has a hand holding unit 1
First, bring both massagers 12, 18 into contact with the shoulder or waist to be massaged. Then, the tips of both treatment elements 12, 18 move so as to be substantially at the same height, and the end surface 9c of the movable iron core 9a separates from the suction surface 6a of the fixed iron core 6. Then, when the switch of the handheld part 1 is turned on, the solenoid drive circuit operates to generate an output voltage at a predetermined cycle, which is the exciting coil.
Applied to 7. When it is applied to the excitation coil 7, it overcomes the spring force of the second return spring 16 and the end surface 9c of the movable iron core 9a is attracted to the attraction surface 6a of the fixed iron core 6, so that the treatment element 12 protrudes to press the shoulder and waist. To do. At this time, the second treatment element 18 moves to the opposite side of the treatment element 12. Further, when the application to the exciting coil 7 is stopped, the movable member 15, that is, the second treatment element 18 is projected by the spring force of the second return spring 16 and presses the shoulder or waist. At this time, the treatment element 12 moves to the side opposite to the second treatment element 18. Therefore, in this tapping massage machine, two treatment elements exposed from the head portion are reciprocated in opposite directions by one solenoid.

As is clear from such an operation, the shoulder and the waist are massaged by the two treatment elements, and the treatment range is wide and the massage is twice as fast as that of one treatment element. You can do it.

In the embodiment, the two treatment elements have been described to reciprocate in opposite directions. However, the plungers may have two movable shafts and the treatment elements may be attached to each of them.
