When used in combination with the first magnesium blocks 100-1 and 100a-1, the first row magnesium block portion 101 and the second row magnesium block are disposed on both edge portions of the hot water mat 200 and the cushion. The vertical contact portion 212 of the part 102 is to be configured to cross each other.

Meanwhile, in the present invention, the base layers 111 and 111a included in the bodies 110 and 110a may have a sufficient thickness in consideration of manufacturing cost or strength during processing, as shown in FIGS. 14 and 15. It is preferably made of a magnesium (Mg) material alone, or based on the magnesium (Mg) material, Al, Cu, Ti, Ni, Si, Cr, Mn, Zn, Zr, Fe, Ca, Li, It would be desirable to be composed of a magnesium alloy containing at least any one of Be.

In addition, the above-mentioned PEO treatment layer 112 formed on the surface of the base layer 111 (111a) is preferably made of a thickness of 4 to 12㎛ range, and furthermore, the thickness of the PEO treatment layer 112 to a range of 2 to 30㎛ By forming a thicker, this will further enhance the film strength of the light metal or metal surface such as magnesium or magnesium alloy to prevent scratches and corrosion from the outside.

In addition, a sandblast treatment layer (not shown) is further formed on the surface of the above-mentioned base layer 111 (111a) before the PEO treatment layer 112 is formed. It will be more advantageous to form the surface coating layer 113 on the surface of the base layer 111 (111a).

In addition, the chemical conversion treatment layer 112a formed on the surface of the above-mentioned base layer 111 (111a) preferably has a thickness in the range of 2 to 3 μm, and furthermore, the thickness is in the range of 0.5 to 6 μm. It is characterized by forming thicker.

Here, the above-mentioned chemical conversion treatment layer 112a is one of chemical treatment methods for producing a stable compound on a metal surface, for example, the base layer 111 (111a) surface, which is a phosphate treatment or black salt. (Black) treatment, chromate treatment and the like.

In addition, a sandblast treatment layer (not shown) is further formed on the surface of the above-mentioned base layer 111 (111a) before forming the chemical conversion treatment layer 112a. It will be more advantageous to form the surface coating layer 113 on the surface of the base layer (111, 111a).

In other words, the present invention is one of the PEO treatment layer 112 or the chemical conversion layer 112a, followed by the formation of the sand blast treatment layer in the order of surface modification treatment on the surfaces of the base layers 111 and 111a mentioned above. This results in enamel coating, ceramic coating, and fluororesin coating on the surface of the base layers 111 and 111a (also referred to as "Teflon coating"). , To further increase the adsorption force for forming any one selected from the electrodeposition (electrodeposition) coating, and furthermore a more uniform and stable surface coating layer on the surface of the base layer (111) (111a) ( 113) can be formed.

On the other hand, the thickness of the enamel coating included in the surface coating layer 113 of the present invention mentioned above is preferably in the range of 60 to 70㎛, and furthermore, to form a thicker in the range of 4 to 90㎛ thickness pipe member 300 Or it may be more advantageous for long-term use to prevent the peeling or peeling of the surface of the body 110, 110a by the high temperature generated from the electric heater member.

Here, the enamel coating is dried at a temperature ranging from 200 to 560 ° C. for 5 to 60 minutes, and then dried at 400 to 850 ° C. in a range of 400 to 850 ° C. As shown in Fig.

In the present invention, the enamel coating is that the base layer (111) (111a) is a thin coating of glass ceramic on the surface of the metal material such as magnesium or magnesium alloy, wherein the enamel glaze used is relatively more than the glaze used in ceramics It is sintered at a low temperature, because the thermal expansion coefficient between the enamel glaze and magnesium or magnesium alloy made of a metal material is different, because baking at too high temperature may cause the enamel glaze to fall off.

In addition, the expansion rate of the enamel glaze is in the range of 0.32 to 0.40% with respect to the temperature difference of 100 DEG C, and another reason for firing at a relatively low temperature is that when the surface of the magnesium or magnesium alloy made of a metal material is fired at an excessively high temperature, It is easy to change.

Therefore, as mentioned above, the enamel glaze fired at a relatively low temperature has a more favorable effect of smoothing or polishing the surface of the magnesium or magnesium alloy included in the base layers 111 and 111a by using a material of low hardness. Done.

In the present invention, the thickness of the ceramic coating included in the surface coating layer 113 is preferably in the range of 30 to 40 mu m, and more preferably in the range of 3 to 60 mu m in thickness.

This further strengthens heat resistance and abrasion resistance, including corrosion resistance to light metal surfaces such as magnesium or magnesium alloy, due to the high temperature generated from the pipe member 300 or the electric heater member mentioned above, thereby damaging the surface of the body 110 and 110a. In addition, it prevents peeling and is more advantageous for long-term use. In particular, far infrared rays emitted from ceramic materials penetrate into the human body to facilitate metabolism.

Also, in the present invention, the thickness of the fluororesin coating included in the surface coating layer 113 is preferably in the range of 20 to 40 mu m, and more preferably in the range of 3 to 60 mu m in thickness.

This is the same as before to prevent damage or peeling off the surface of the body (110, 110a) with the heat resistance function due to the high temperature generated from the pipe member 300 or the electric heater member, in particular on the surface of the body (110) (110a) Non-adhesive function to prevent foreign matters from sticking.

In addition, in the present invention, the thickness of the electrodeposition coating included in the surface coating layer 113 is preferably in the range of 20 to 25 μm, and furthermore, by forming a thicker thickness in the range of 6 to 50 μm, the body 110 (110a). By coating uniformly to the inside of the outer skin as well as the inside, thereby improving the rust resistance and weather resistance of the first magnesium block (100-1, 100a-1) and the second magnesium block (100-2) and the body (110) (110a) serves to prevent corrosion of the surface.

On the other hand, the present invention, as shown in Figures 2, 6, 10 attached to the opening 122 provided in the holder portion 120 is an opening in the range of 30 degrees to 150 degrees so that the inclined surface 123 is provided on both sides By forming the angle (K1), it is easier to insert and fasten the pipe member 300 or the electric heater member (not shown) to the holder portion 120 is provided in a round shape for circulating the hot water through it. It works by letting it work.

In other words, the pipe member 300 or the electric heater member provided in a round shape is easily pushed into the holder portion 120 along the inclined surface 123 formed on both sides of the opening 122.

Further, in the present invention, as another method for fastening the pipe member 300 or the electric heater member (not shown) to the holder 120, for example, the pipe member 300 provided in a round shape is provided. The first end 301 or the second end 302 of the first magnesium block (100-1, 100a-1) and the longitudinal direction of the holder portion 120 provided in the second magnesium block (100-2) It may be possible to fasten by inserting directly into P1).

The inner diameter of the holder 120 is preferably in the range of 4 to 24 mm in consideration of the diameter of the pipe member 300 or the electric heater member. It may be possible to make various diameters in a larger or smaller range depending on medical devices and the like.
