Description

Roller type massager with heating function {ROLLER TYPE MASSAGER WITH HEATING FUNCTION}

The present invention relates to a roller-type massager having a heating function, which performs a massage while rotating in contact with the skin, but also provides a steaming function through self-heating.

As an example of a roller type massager having a heating function, there is a “Roller rotation type thermal massage device” disclosed in Patent Publication No. 10-2018-0112959. 1 shows an example of a roller rotation type thermal massage device as a prior art.

Referring to FIG. 1, in the roller rotation type thermal massage device of the patent document, the roller 2 is coupled to the body 1 and rotates, and power is supplied to the hot wire 3 of the roller 2 to is designed to generate heat. The hot wire (3) is connected to the rotation shaft (4) of the roller. Thermal oil 5 is sealed in the roller 2 so that the heat generated by the hot wire 3 is transferred to the outer circumferential surface of the roller 2 .

In the above patent document, since the hot wire 3 is connected to the rotation shaft 4 of the roller, a considerable gap is generated between the hot wire 3 and the outer circumferential surface of the roller 2, so the heat generated from the hot wire 3 is transferred to the roller ( In the process of being transferred to the outer circumferential surface of 2), a large heat loss occurs. Although the thermal oil 5 is sealed in the roller 2, there is a problem that heat loss cannot be fundamentally prevented because the heat transfer efficiency of the thermal oil 5 is limited. In addition, in this case, there is a risk that the heat transfer oil 5 leaks out due to a gap in the connecting portion of the rotating shaft 4 of the roller due to use.

The support 10 serves as a handle, and the lower part has a handle part 11 having a curved shape so that a person can easily hold it by hand, and the upper part has a fastening member p1 for fixing the rotation support shaft 30. It is formed of a mounting portion 12 in which a fitting hole 12a is formed.

The brush 20 is mounted on the support 10 and is designed to draw current from the outside. A plurality of wires (w) drawn from the outside of the roller type massager are connected to the brush 20 . The brush 20 is formed in a hollow cylindrical shape. The brush 20 includes a brush body 21 and a protrusion 22. One surface of the brush body 21 comes into contact with the support 10 and a first pole 21a is formed on the other surface. The protrusion 22 has a smaller diameter than the brush body 21 and protrudes toward the slip ring 60, and a second pole 22a is formed on the end surface. The second pole 22a has a polarity opposite to that of the first pole 21a. The protruding portion 22 extends from the brush body 21 in a stepped shape, has the same axis, and together forms an inner circumferential surface.

The rotation support shaft 30 is mounted in the hollow of the brush 20 and extends to the other side of the brush 20. One end of the rotation support shaft 30 is mounted on the brush 20, and a bearing 40 is fitted to the other end. A slip ring 60 is disposed between the brush 20 and the bearing 40, and the slip ring 60 is fitted to the rotating shaft 30 together with the bearing 40. The rotation support shaft 30 is mounted on the support 10 by means of a fastening member p1.
