Description

[Detailed explanation of the idea] (Industrial application field) This invention relates to the structure of a moxibustion heater.

(Prior Art) Generally, a moxibustion heater is a device that stimulates the affected area by bringing ceramics into direct contact with the affected area (acupuncture points), fixing it with tape, etc., and raising the temperature to an appropriate level.

At this time, by using ceramic on the surface that comes into contact with the affected area, far infrared rays are emitted and penetrate well into the skin, which has the advantage of enhancing the thermal effect.

(Problems to be solved by this invention) Conventionally, this type of heater has a structure in which a nichrome wire and a heat insulating material are placed on the back side of a ceramic plate in that order, and the whole is fixed with a metal frame.

FIG. 5 shows a conventional embodiment, FIG. 6 is a sectional view of FIG. 5, and FIG. 7 is a bottom view of FIG.

In the conventional embodiments shown in FIGS. 5, 6, and 7, a heat insulating material 4 is adjacent to a ceramic plate 1, and a recess is provided on the side where the heat insulating material 4 is in contact with the ceramic board 1, and a nichrome wire is provided therein. 3 is embedded.

The metal frame 2 is provided with hooks 5, 5 so that the ceramic plate 1 and the heat insulating material 4 are brought into close contact with each other.

However, in this structure, a difference in level occurs between the metal frame 2 and the ceramic plate 1, which causes discomfort when the metal frame 2 and the ceramic plate 1 are pressed against the affected area.

In addition, metal heating elements such as nichrome wire 3 inevitably deteriorate due to the time they are energized, posing a problem in long-term durability.

Furthermore, since the heat insulating material 4 is required to have a thickness equal to or larger than the diameter of the nichrome wire 3, there is a drawback that the overall thickness becomes large.

Therefore, the temperature rise characteristic is poor, and the fixation to the affected area with tape or the like increases in weight, making it unstable, resulting in problems.

(Means for solving the problem with this invention) This invention was made in view of the above-mentioned circumstances, and by using a thin and semi-permanent resistive thin film for the heating element, the overall thickness and weight can be reduced. To provide a moxibustion heater that is lightweight, has a quick rise in temperature, and evenly heats the entire body.

(Example) Hereinafter, an example of this invention will be described with reference to the drawings.

FIG. 1 is an overall perspective view showing an embodiment of the present invention;
FIG. 2 is a sectional view of FIG. 1. FIG. 3 is a state diagram immediately before coating with heat-resistant resin in the manufacturing process.

In FIG. 2, the moxibustion heater is composed of a resistive thin film 6 formed on the entire surface of a ceramic plate 1, electrodes 7 printed thereon, a heat-resistant synthetic resin 9 covering them, and a power cord 10.

Here, the resistive thin film, which is a heating element provided on the ceramic plate 1, is composed of a resistive thin film 6 and an electrode 7, which are formed by adhering indium oxide or a mixture of indium oxide and a small amount of tin oxide by spraying or the like. There is.

The thickness of the resistive thin film 6 is 1 μm or less, and unlike metal heating elements such as nichrome wire 3, it hardly deteriorates and has semi-permanent durability.

The heat-resistant synthetic resin 9 also serves as insulation between the electrodes, and is firmly laminated on the ceramic plate 1 and the resistive thin film 6 to prevent deformation, cracking, etc. due to heat generated by the heating element over a long period of time.

The entire opposite surface of the ceramic plate 1 is exposed.

The heat-resistant synthetic resin 9 may generally be silicone resin, epoxy resin, or the like.

FIG. 3 shows the state before the heat-resistant synthetic resin 9 is laminated, and the electrodes 7 are printed in parallel on the resistive thin film 6, and the power cord 10 is fixed thereon with a soldering part 8 or the like.

FIG. 4 shows another embodiment according to the present invention.

A resistive thin film 6 is formed on the ceramic plate 1, and printed electrodes 7 are provided at both ends, and the electrodes 7 are connected to a power cord 10. The entire body is then covered with a heat-resistant synthetic resin 9.

(Effects of the invention) With these configurations, the temperature of the moxibustion heater rises quickly, and the entire area is evenly heated.
Durability for long-term use is improved, and since heat-resistant synthetic resin is used, no heat insulating material is required, making it possible to reduce the overall thickness and weight.
