  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to these embodiments.

  As shown in FIGS. 1 and 2, the gas dissolver 1 according to the present invention has a simple structure and can be detachably incorporated into an existing household shower unit 21 without using a special connector.

  Here, as shown in FIG. 3, the existing shower unit 21 generally includes a hot and cold water mixing plug body 22, an adapter 23, a shower hose 24, and a shower head 25.

  In the hot and cold water mixing plug body 22, one end side of the water and hot water flow paths is embedded in the wall 26 and connected to the respective supply sources, and the other end (the front side of the wall 26) is connected. Handles 22a and 22b for adjusting the flow rates are provided in the flow paths of water and hot water, respectively. On the side where water and hot water are mixed, a discharge port 22c having a thread groove for discharging the mixed water is provided.

  In addition to the hot water mixing plug main body shown here, a hot water mixing plug main body 22 including a swing faucet and a lever for switching the water discharge direction between the faucet and the shower head 25 is also widely used. In that case, what is necessary is just to connect the gas dissolver 1 of this invention to the elbow branched from the hot-water-mixing stopper main body in a shower flow path.

  The adapter 23 includes an inner screw and / or an outer screw, and connects the discharge port 22c and the end portion 24b of the shower hose without water leakage through the packing 23a and the packing 23b.

  The shower hose 24 includes a flexible tube 24 a, a terminal portion 24 b connected to the discharge port 22 c via the adapter 23, and a tip portion 24 c at the other end screwed to the end of the shower head 25.

  The shower head 25 is connected to the tip 24c of the shower hose 24 and discharges the shower water 25a from the water spray plate.

  As shown in FIG. 1, the gas dissolver 1 according to the present invention is used by being screwed into an adapter 23 of an existing household shower unit 21 and an end portion 24b of a shower hose 24 to dissolve the gas. The shower unit 21a is formed.

  As shown in detail in FIG. 2, the gas dissolver 1 as an example of the present invention is detachably attached to a hot and cold water mixing plug body 22 and a shower hose 24 that are flow paths through which flowing water passes. It consists of a joint 9 which is attached to the part 1a and communicates with the cylinder 10. The cylinder 10 is provided with a regulator 10 b that adjusts the gas pressure, one end of the joint 9 is connected to the regulator 10 b, the other end is connected to the cylinder part 1 a, and carbon dioxide in the cylinder 10 passes through the joint 9 and the cylinder part Sent in 1a.

  The cylindrical part 1a is considerably mixed with the outer cylinder 2, the first adapter 3, the inner cylinder 7, and the second adapter 8 in the raw water 11 flowing into the cylindrical part 1a and mixed with the carbon dioxide 10a. By flowing the mixture, the carbon dioxide 10a is dissolved in the flowing water, and the gas-dissolved water 11a is generated and discharged (sent to the shower hose 24).

  The outer cylinder 2 is hollow inside and includes upper and lower screw portions (inner screws 2a and 2b). On the outer circumference, a monkey wrench, a pliers wrench, a spanner, and the like that are screwdrivers for tightening and screwing are held and rotated. A flat portion 2c that serves as a clamping portion of the tool is provided, and a hole 2d that is connected (screwed) to the joint 9 is provided. A screw 9a at the tip of the joint 9 is screwed into the hole 2d and is detachably attached.

  The first adapter 3 is connected downstream of the outer cylinder 2. The outer periphery is provided with a corner portion 3a that serves as a holding portion of the holding rotary tool. The upper portion of the outer screw 3b is screwed into the inner screw 2b of the outer cylinder 2 above the corner portion 3a, and the shower hose 24 is below the corner portion 3a. An external screw 3c that is screwed into the end portion 24b is formed, and an opening 3d that discharges the gas-dissolved water 11a is provided at the lower end.

  The inner cylinder 7 is disposed in close contact with the outer cylinder 2 on the upstream side of the first adapter 3, and the annular recess 7 a and the recess 7 a, which are flow paths through which carbon dioxide 10 a passes, are provided at a plurality of locations. Here, through holes 7b communicating with the inside are formed at four positions facing each other. The through-hole 7b includes a mortar shape that becomes thinner as it deepens, and makes the gas vortex and easily flow into the internal running water. By providing four through holes 7b at equal intervals in the structure as shown in FIG. 2, the gas is made low pressure (0.15 Mpa) with respect to running water connected to tap water (0.15-0.39 Mpa). The gas can be efficiently injected and dissolved in the internal flowing water of the inner cylinder 7. In the conventional gas dissolving apparatus, such low-pressure gas cannot be stably injected and dissolved in running tap water. By using such a low-pressure gas, the amount of gas used for dissolution can be saved, the danger of high pressure is avoided, and the safety of the apparatus is enhanced.

  The inner cylinder 7 has an inner diameter that is narrower in the flowing direction and wider in the other direction, and the inner wall surface 7c is trapezoidal in the section of the flowing direction. By reversing the top and bottom, the water pressure can be adjusted. When the water pressure in the flow path is low, a narrow opening is positioned on the downstream side as shown in FIG. 2, and when the water pressure in the flow path is high, the top and bottom of FIG. 2 are reversed and a wide opening is positioned on the downstream side. Alternatively, by reversing the gas dissolver 1, the inner cylinder 7 is reversed, so that the water pressure can be adjusted. If the gas dissolver 1 is reversed, the positioning of the hole 2d and the through hole 7b does not need to be considered again and is simple.

  The second adapter 8 is connected upstream of the outer cylinder 2. A head 8a serving as a clamping portion of the clamping rotary tool is provided on the outer periphery, which is upstream of the road, and an inner screw 8b connected to the adapter 23 is formed inside the head 8a. An external screw 8c that is screwed into the internal screw 2a is drilled.

  The second adapter 8 is connected to the discharge port 22 c of the hot and cold water mixing plug body 22 via the adapter 23. As a result, as shown in FIG. 1, the gas dissolver 1 is screwed into the adapter 23 of the existing household shower unit 21 and the end portion 24b of the shower hose 24 to form the gas dissolution shower unit 21a. To do.

  In this way, the gas dissolver 1 is positioned by sandwiching the inner cylinder 7 between the first adapter 3 and the second adapter 8.

  The gas re-dissolver 31 shown in FIG. 4-11 is connected to the downstream side of the gas dissolver 1 of the present invention and upstream of the shower head 25 by connecting the inlet side 32 and the outlet side 33 respectively, so that surplus gas is provided. Reduced and high concentration gas dissolved water can be generated.

  As shown in FIG. 11, the gas re-dissolver 31 has a second flow path 34. The second flow path 34 is bent continuously from the inlet 34a connected to the inlet side 32 to the left and right, the bent portion is a thick path 34b, the narrow path 34b is between the thick path 34b and the thick path 34b, and the outlet side 33 is connected. Here, the thick path 34b and the narrow path 34c can be seen as having the same diameter, but in this embodiment, the thickness differs in the vertical direction. Such second flow paths 34 are stacked in a plurality of rows in the gas re-dissolver 31.

  The diameter of the second flow path 34 thus formed is curved and continuous in a bowl shape, and expansion pressure and contraction pressure act on flowing water to promote the dissolution of gas in water. By stacking such channels in the vertical direction, the gas can be efficiently dissolved in water in a small space.
