Hereinafter, a preferred embodiment of the warmer using the present invention dynamic magnetic barley stone ball will be described in detail with reference to the drawings.

As shown in FIG. 1 and FIG. 3, the present invention is a heating unit 10 is composed of a heat collecting unit 20, the main body 30 and the handle portion 40.

The heating unit 10 is the ganban stone ball 11 produced in the annular shape by firing the ganban stone at 1300 ℃ a large amount is attached to the front surface of the synthetic resin plate 13 with epoxy or instant adhesive solution, the magnet 3 is the synthetic resin plate Attached symmetrically to the front of (13), the fixing groove 33 is perforated on one side of the synthetic resin plate (13).

The heat collecting part 20 has an annular aluminum plate 21 having a circular plate shape attached to the heating part 10, and is wound and cut by a nickel chrome hot wire coil 22 to which power is applied by connecting electric wires at both ends thereof. The metal plate 21a is attached to the aluminum plate 21.

The main body 30 has a band fixing part 31 for fixing the band so as to be in contact with the human body by a band on the rear surface, and one side of the rotating piece 36 having a curved shape on the inside thereof with the rotating shaft 37. On the other side, the temperature holding sensor 35 is installed on the other side to sense the temperature of the heat collecting part 20 and turn on / off the power.

In addition, the heat collecting part 20 is attached to the heating part 10 and is coupled to the main body 30.

The handle portion 40 has a fixing protrusion 45 is inserted into the fixing groove 33 of the heating portion 10 at the front end, the locking portion 41 is installed on the side front end so as to hang clothes, etc., A temperature controller 42 for rotating the temperature holding sensor 35 is installed at the front end of the upper surface, and a switch 43 for applying and cutting off power is attached to the center of the upper surface.

The action of the heater configured as described above is as follows.

First, in order to operate the heater 1, by pressing the switch 43 installed in the handle portion 40 to turn on the power is applied. Then, the applied power flows to the nickel chrome hot wire coil 22 wound on the metal plate 21a of the heat collecting portion 20 to generate heat. And the heat generated from the heat collecting portion 20 is transferred to the synthetic resin plate 13 of the heating portion (10).

As described above, the heat transferred to the synthetic resin plate 13 of the warmer 10 transfers heat to the elvan ball 11. Then, far infrared rays are radiated from the heated elvan ball 11. When the heat is transferred to the elvan ball 11 as described above, the warmer 10 is formed on the front surface of the heater 1 in contact with a body part in which various pain such as muscle pain occurs. At this time, in the warmer (1) heat and far infrared rays are delivered to the human body to promote blood circulation and activate metabolism. Then, after applying a cream or the like to the skin, a thin vinyl cover is covered with the warmer 1 to be rubbed with the skin to obtain a skin beauty effect. And since the synthetic resin plate 13 has a low thermal conductivity, it does not burn the human body in contact with the heater 1.

And, when the heater 1 needs to be in contact with the human body for a long time, the rotating piece 36 which is uttered on the rotating shaft 37 by rotating the temperature controller 42 rotates, and the rotating piece 36 rotates. As a result, the temperature holding sensor 35 delivered to the pivoting piece 36 is rotated to place the temperature holding sensor 35 at a predetermined position. That is, when the temperature controller 42 is rotated to the position of the steel, the temperature holding sensor 35 is rotated so that the nickel chrome hot wire coil 22 is moved away from the wound metal plate 21 a and is at the position of the aluminum plate 21. Since only the radiant heat in the heat collecting unit 20 is detected, power is not easily cut off by the temperature maintaining sensor 35. Therefore, even if high heat is generated in the heat collecting unit 20 and transmitted to the heat unit 10, the temperature maintaining sensor 35 detects only radiant heat, so that power is continuously applied to maintain the high temperature in the heater 1 that contacts the human body. Can be.

On the contrary, when the temperature controller 42 is rotated to the position of the medicine, the temperature maintaining sensor 35 is rotated so that the nickel chromium wire coil 22 is in direct contact with the wound metal plate 21a to detect contact heat. When high heat occurs in the heat portion 20, the power is quickly cut off by the temperature maintaining sensor 35. Therefore, when high heat is generated in the heat collecting part 20, the temperature maintaining sensor 35 detects contact heat and when the temperature is higher than the set temperature of the temperature maintaining sensor 35, the heater is cut off to contact the human body in the heater 1. Maintains moderate heat by preventing high heat from occurring.

In addition, when the power is cut off by the temperature maintaining sensor 35 as described above, since the power is not applied to the heat collecting unit 20, no heat is generated in the heat collecting unit 20, so that the temperature of the heater 1 is lowered. . When the lowered temperature falls below the temperature set in the temperature holding sensor 35, the temperature holding sensor 35 applies power again to generate heat in the heat collecting unit 20, thereby heating the heat unit 10. To pass. Therefore, since the temperature is controlled even when used in contact with the human body for a long time, the heater 1 is prevented from being damaged or burned to the human body, and a high temperature, a medium temperature, or a low temperature can be selected and brought into contact with the human body.

And, in order to contact the warmer (1) to the human body for a long time, such as when going to bed by hanging the catch portion 41 formed on the front of the handle portion 40 to the clothes and so not fall, and the warmer (1) joints such as ankle or wrist In order to make contact with the site for a long time, the heater 1 is brought into contact with the contact part, and then the band is wound around the band fixing part 31 to fix the heater 1 to the contact part.

By passing to the steamer (55).

In this way, the heat transmitted to the steamer 55 heats the mugwort filled in the steamer 55 so that the steaming is generated. Hungi fished in this way is discharged through a plurality of discharge holes (57) perforated in front of the jjimjilgu cover 56 to act on the human body in contact with the heater (1) to promote blood circulation.

Then, when the temperature control sensor 54 is installed on the inner rear of the steaming sphere body 51, when the heat generated in the steaming sphere 50 becomes higher than the temperature set in the temperature control sensor 54, the steaming sphere 50 When the power applied to the cut off, on the contrary, when the heat generated in the steaming sphere 50 is less than the temperature set in the temperature control sensor 54, the power to the steaming sphere 50 is applied. Thus, high heat is generated in the hot air balloon 50 to prevent burns to the human body in contact with the heater (1).

After lumping as described above, after separating the culprit cover 56 from the culprit body 51, the steamer 55 is separated from the culprit body 51. Then, after removing the mugwort used in the steamer 55, the fresh mugwort is put back and the steamer 55 is inserted, and then the steaming ball cover 56 is coupled to the steaming ball body 51.
