[0012] The alumina germanium ceramic composition according to the present invention comprises an alumina (Al 2 O 3) powder and

twenty three

In addition, it is configured to contain acid-germanium (GeO) powder. In this case, alumina powder and acid

2

The mixing ratio of germanium fluoride powder is 60.0 to 90. Owt% for alumina powder and 10 to 40 wt% for germanium oxide powder.

The alumina powder preferably has an average particle size of 50 m. Thus, when alumina powder with an average particle size of 50 m is used, even if it is fired at a temperature of 1300 ° C or higher, it does not become a dense ceramic (sintered body) but absorbs water. The porous alumina (porous alumina) before and after 30% can be obtained.

As the germanium constituting the above-mentioned oxide germanium powder, one having a purity of 99.999% or more is used.

(In order to improve the slow solubility of germanium ions in water, silicon dioxide)

2

In this case, it is preferable to mix the powder, and the silicon dioxide powder is comprised of 10 to 20 wt%.

[0013] The alumina-germanium ceramic sintered body of the present invention is obtained by sintering the above-described alumina-germanium ceramic composition, and its production method will be described with reference to FIG.

First, an alumina powder having an average particle diameter of 50 m, a silicon dioxide powder, and an acid gel germanium powder are prepared. As described above, the mixing ratio of each powder is 60.0 to 90. Owt% for alumina powder, 10 to 40 wt% for germanium oxide powder, and 10 to 20 wt% for silicon dioxide powder.

Next, after sufficiently mixing the alumina powder, silicon dioxide powder and germanium oxide powder, it is subjected to a deironing treatment, and then filtered and dried. Next, the dried mixture of alumina, silicon dioxide, and germanium oxide is pulverized, added with a binder, kneaded, formed into a predetermined shape (for example, spherical), and then dried.

Finally, the alumina germanium ceramic sintered body of the present invention can be obtained by firing at a predetermined temperature (for example, 1300 ° C.).

By using alumina powder with an average particle size of 50 m as described above, 130 Even if it is fired at a temperature of 0 ° C. or higher, it does not become a dense ceramic (sintered body) but can be made of porous alumina having a water absorption rate of around 30%. For this reason, germanium ions can be eluted into water by contacting with the hydro-acidic germanium infiltrated into the many pores of the porous alumina constituting the sintered body.

Incidentally, the diacid key is used to maintain the strength of the porous alumina as a sintering aid, and the alumina germanium ceramic ceramic is formed by covering the diacid key. The combined body improves the slow solubility of germanium ions in water.

[0014] Since the alumina germanium ceramic sintered body according to the present invention is in contact with water and elutes germanium ions into the water, the alumina germanium ceramic sintered body is incorporated into, for example, a shower head or a bathtub. By using it in the body, the whole body can enjoy the health promotion effects of germanium such as improvement of stiff shoulders and muscle pain by promoting blood circulation, and blood purification.

FIG. 2 is a schematic explanatory view schematically showing an example of a shower head using the alumina germanium ceramic sintered body according to the present invention. The shower head 10 includes a grip portion 12 and a head portion 14. And comprising.

The grip portion 12 has a hollow and substantially cylindrical shape, and a hose connection portion 14 connected to a shower hose (not shown) is provided at the lower end thereof. It will flow into the grip 12.

A cartridge-type water purification member 18 is accommodated in the grip portion 12. The water purification member 18 is formed by attaching cylindrical caps 22 to the upper and lower ends of a cylindrical fibrous activated carbon 20, and the internal spaces of the fibrous activated carbon 20 and the cylindrical cap 22 are communicated with each other so 2 4 is forming. Further, a gap is formed between the fibrous activated carbon 20 and the inner peripheral surface of the grip part 12, and the gap is formed with the water purification flow path 26.

In FIG. 2, reference numeral 28 denotes a purified water or raw water switching lever. When “purified water” is selected by operating the switching lever 28, a means such as a valve body (not shown) linked to the switching lever 28 is used as a fibrous activated carbon 20. The opening of the cylindrical cap 22 at the lower end is closed. As a result, the raw water flowing into the grip part 12 is guided to the purified water flow path 26, passes through the fibrous activated carbon 20 from the outside toward the inside, and enters the purified water / raw water flow path 24, and then the head part 14 Flows in. Raw water is on In the process of passing through the fibrous activated carbon 20, impurities such as chlorine and bacteria that adversely affect the hair and skin are adsorbed and removed to form purified water.

When “raw water” is selected by operating the switching lever 28, a means such as a valve body (not shown) linked to the switching lever 28 is used as the opening of the cylindrical cap 22 at the lower end of the fibrous activated carbon 20. In order to release the water, the raw water that has flowed into the grip portion 12 passes through the purified water and raw water flow path 24 with low pressure loss and flows into the head portion 14.

[0017] The head portion 14 is hollow inside, and a large number of water jets 30 are provided at the tip. In the head portion 14, a spherical alumina germanium ceramic sintered body 34 and a spherical titanium ceramic 36 housed in a mesh container 32 having a large number of communication holes are disposed. The alumina germanium ceramics sintered body 34 has 32 pieces having a diameter of about 6 mm, and 60 titanium ceramics 36 are housed in a force mesh container 32. Of course, the shape, number, and dimensions of the alumina germanium ceramic sintered body 34 and the titanium ceramic 36 housed in the mesh container 32 can be changed as appropriate.

[0018] The titanium ceramic 36 generates negative ions by a water crushing method (Leonard method), and a large amount of negative ions is generated when water collides with the titanium ceramic 36! / RU

Negative ions make acid water neutral and weak alkalinity, making it good for the body, making it water, suppressing active oxygen that adversely affects the body, relaxing the body and healing naturally It exhibits various health promotion effects such as the effect of improving strength.

The force that generates negative ions even when water collides with the alumina germanium ceramic sintered body 34. By using the titanium ceramic 36 in combination, a larger amount of negative ions can be generated.

In addition, when water collides with the alumina germanium ceramic sintered body 34 and the titanium ceramic 36, the water cluster (the molecular group of water) becomes smaller, so that the water permeability to the body increases, and after taking a shower. Moisturizing effect is improved.

Thus, in the shower head 10 of the present invention, the alumina germanium ceramic sintered body 34 according to the present invention is disposed in the middle of the flow path of water from the inlet 16 to the outlet 30. The water is in contact with the alumina-germanium ceramics sintered body 34 and the germanium Can be exposed to the skin and the hair, so that users can have various kinds of germanium for improving shoulder stiffness and muscle pain by promoting blood circulation and blood purification. Can enjoy the health promotion effect of the whole body. In addition, since the titanium ceramic 36 that generates a large amount of negative ions is arranged in the middle of the flow path, various health promotion effects by the negative ions can be enjoyed.

Further, the fibrous activated carbon 20 constituting the water purification member 18 disposed in the middle of the flow path can adsorb and remove chlorine and other impurities such as bacteria that adversely affect the hair and skin.

In addition, the alumina germanium ceramics sintered body 34 and titanium ceramics 36 make it possible to reduce the size of the water cluster, increasing the water permeability to the body and improving the moisturizing effect after taking a shower. Can be made.
