The present invention relates to a massage device for direct current that can be used as a massage by hitting each part of the body using an electromagnet, and to adjust the strength of the massage by adjusting the stroke stroke of the plunger. A typical massage device was simply to perform massage by reciprocating the ferrite core continually with a constant period in a coil wound bobbin using an electromagnet.

Since the massage device of the related art cannot adjust the speed and intensity of massage step by step, it is impossible to select an appropriate speed and intensity suitable for the user's taste, and it operates at the same speed and intensity. I was unable to get the effect of my massage.

The present invention is to solve the conventional problems as described above, and has the following object.

First, by adjusting the stroke of the plunger reciprocating in the bobbin with a control cap provides a massage device for direct current that can freely adjust the strength of the massage as desired by the user.

Second, by providing several massage bodies in various shapes at the tip of the striking rod coupled to the plunger, it is possible to selectively combine the massage bodies according to the user's taste, so that the user's mental stability can be improved and accordingly, the massage effect is more effective. The present invention provides a massage device for direct current that can be obtained.

Thirdly, it is possible to separate and remove the striking rod from the plunger and to use the rubber cap on the tip of the body, so that massage can be performed by indirect striking. The present invention provides a massage device for direct current.

The device of the present invention for achieving the above object is elastically installed by the spring plunger interposed reciprocating in the bobbin coil wound, the control cap is bonded to the buffer rod for adjusting the stroke of the plunger bobbin on the plunger side It is achieved by providing a massage device for direct current mounted through the bobbin is provided with a striking rod mounted on the plunger to the massage body.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

That is, in the massage device for direct current of the present invention, as illustrated in FIGS. 1 and 2, a cylindrical gun bobbin 20 in which a coil 26 is wound in a case 11 and a case 11 of the body 10. ) Is fixed and inserted into the plunger groove 22 of the bobbin 20, the spring 60 is inserted into the plunger 30 is elastically inserted and installed, the control cap 40 is bonded to the buffer rod on the bobbin of the plunger side ) Is screwed to the plunger 30 is a striking rod 50, the massage body (51a) is attached to the front end is coupled through the bobbin (20).

The main body 10 is provided with a cup-shaped case 11 having a perforated rod 13 in the center of the disc 12 and a semi-circular ring protrusion 14 protruding from the outer periphery of the disc 12, and a grip portion in the case 11. The bag 15 in which the 16 was formed is mounted integrally.

In addition, the main body 10 may be manufactured using only the case 11 in a state in which the bag 15 is removed and installed on a chair or a bed or a mattress.

The bobbin 20 is a blow rod 21 and the plunger groove 22 is formed in the center and the ring groove 23 and the male screw 24 is formed on the outer periphery, the bobbin (11) on the disc surface of the plunger groove (22) A washer-type buffer ring 25 is attached to prevent the impact sound that 20) and the plunger 30 collide with each other.

The plunger 30 has a cylindrical rod made of ferrite core, and a spring settling groove 31 and a female screw hole 32 are formed at one side thereof.

The control cap 40 is a cylindrical buffer rod 42 is attached to the inner surface of the cap-shaped disc formed with the internal thread 41 on the inner circumferential surface. The striking rod 50 has a disc-shaped massage body 51a made of a material having a good elasticity at its tip, and a male screw 52 corresponding to the female thread hole 32 of the plunger 30 is formed at the rear end thereof. have.

Figure 3 shows another embodiment of the striking rod according to the present invention, Figure 3a is a mass of hemispherical dolly 53 protruding to the mass (51b) at the tip of the striking rod 50, massage body of the first and second degrees (B) is different from that of the mass 51b of FIG. 3a in that the fluid chamber 54 in which liquid or gas is hermetically filled is provided on the inner surface of the mass 51c at the tip of the striking rod 50. will be. The hemispherical dolly 53 of the massage body 51b may be formed to protrude into a permanent magnet to obtain a medical effect.

4 shows another embodiment of the massage body according to the present invention, in which the striking rod 50 is removed and the semicircular ring recess 55 is defectively corresponding to the semicircular ring protrusion 14 of the case 11. What is provided with the formed cap-shaped massage body 51d is different from the massage bodies 51a, 51d, and 51c of FIG. 1 thru | or FIG.

Referring to the operation and effects of the present invention configured as described above are as follows.

When the DC power is intermittently energized with a certain period through a relay or a timer, a magnetic force is generated intermittently whenever it is energized by the coil 26 wound on the bobbin 20.

At this time, as the plunger 30 is pulled forward by the generated magnetic force, the massage bodies 51a to 51c of the striking rod 50 screwed to the plunger 30 strike a predetermined part of the body to perform the massage. .

When the DC power is disconnected and the magnetic force generated in the coil 26 is removed, the plunger 30 is returned to its original position by the elastic force of the spring 60 inserted between the bobbin 20 and the plunger 30. As the DC power supply has a certain cycle and the electricity supply and disconnection are continuously repeated, the above-described action is repeated to obtain a massage effect.

As a method for adjusting the strength of the massage by rotating the control cap 40, the female screw 41 of the adjusting cap 40 screwed to the male screw 24 of the bobbin 20, the adjusting knife 40 is moved, As it is reversed, the stroke of the plunger 30 is adjusted. In other words, the shorter the stroke, the weaker the massage strength, and the longer the stroke, the stronger the massage strength.

As described above, the present invention can freely adjust the strength of the massage as the user desires, and can be used by selectively combining the massage bodies 51a, 51b, 51c, and 51d according to the user's taste. As a result, a more stable and effective massage effect can be obtained, and massage can be performed by an indirect blow, so that a massage effect can be obtained with a softer touch.
