It is attached to the outer case main body 93 and the inner case main body 94 by closing between the inner circumference of the cylinder of the main body 93 and the outer circumference of the cylinder of the inner case main body 94.
As a result, the cartridge case 91 has a processing layer storage space EP (storage space) partitioned (formed) by the case main bodies 93 and 94 and the case lids 95 and 96.

Each case lid 95, 96 has a plurality of lid liquid holes 97, and each lid liquid hole 97 penetrates each case lid 95, 96 and communicates (opens) with the storage space EP.

The liquid processing layer 92 is stored in the processing layer storage space EP of the cartridge case 91. The liquid treatment layer 92 (purifying material) is stored in the treatment layer storage space EP so that the liquid can pass through (passable).
The liquid treatment layer 92 is a purifying material or the like that changes the water quality by contact with liquid (water). The purifying material is a material having a dechlorination function, and is, for example, calcium sulfite, ascorbic acid, activated carbon, or the like. The purifying material removes chlorine from the liquid (water).

In the dechlorination cartridge CT, the outer peripheral surface of the cylinder 93A (outer peripheral surface of the cylinder) of the outer case body 93 is brought into contact (contact) with the inner circumference 12A of the liquid inflow hole 12 (inner circumference 10A of the liquid flow path hole 10) to liquid. It is arranged (inserted) in the inflow hole 12.
The dechlorination cartridge CT penetrates the support shaft 30 of the vortex forming main body 21 into the inner case main body 94 and is fitted onto the support shaft 30.
The dechlorination cartridge CT is arranged in the cartridge storage space CJ between the mesh plate 61 and the cap 62. In the cartridge storage space CJ, the dechlorination cartridge CT has the case upper lid 95 in contact with the mesh plate 61, the case lower lid 96 in contact with the cap 62, and the mesh plate 61 and the cap 62 (cartridge holder 4). It is sandwiched and held.

In FIG. 22, the liquid flows into the liquid inflow hole 12 (liquid flow path hole 10) from the inflow port 8 of the liquid flow path body 1, and each cap liquid hole 68 of the cap 62 and each lid liquid of the case lower lid 96. It flows into the liquid treatment layer 92 (treatment layer storage space EP) of the dechlorination cartridge CT through the hole 97.
The liquid flows through the water treatment layer 92, chlorine is removed by a purifying material, and flows into the liquid inflow space H through each lid liquid hole 97 of the case upper lid 95 and each mesh liquid hole 64 of the mesh plate 61. To do.
As a result, the bubble generator X can flow out the dechlorinated bubble-containing liquid from the outlet 9.
The dechlorination cartridge CT can be taken out from the liquid inflow hole 12 and the support shaft 30 by removing the cap 62 from the support shaft 30 and pulling the cartridge case 91 toward the inflow port 8, and is for new dechlorination. It can be replaced with a cartridge CT.

The present invention is most suitable for mixing and dissolving macro-unit bubbles (micro bubbles) and nano-unit bubbles (ultrafine bubbles) in a liquid.
