Finally, the suction tube connecting member 21 is fitted into the upper end opening of the cartridge case 8, and the upper part in the cartridge case 8, that is, between the bacteriostatic filter layer 15 and the suction tube connecting member 21. By forming the water storage chamber 16, it is possible to obtain the water preparation cartridge 6 used for the above-mentioned skin water preparation device, and to provide the raw water suction port (the lower end opening of the cartridge case 8) 9) Protrusions (legs 37) projecting downward are provided.
[0020]
When the cartridge 6 is manufactured as described above, the flange 36 provided at the lower edge of the cartridge case 8 serves as a positioning and retaining function when the bottom filter 10 is attached to the lower edge of the cartridge case 8, The bottom filter 10 can be appropriately attached to the lower end opening of the cartridge case 8, and the bottom of the cartridge case 8 can be easily formed. Further, since the inner hole 8a of the cartridge case 8 is formed as a tapered hole, only the diameters of the circular bottom filter 10, the first and second filters 12 and 14, the fibrous activated carbon, and the bacteriostatic filter are determined. These can be fitted and fixed at predetermined depth positions (attachment positions) in the cartridge case 8, respectively, and multiple step surfaces are provided on the inner peripheral surface of the cartridge case 8 to lock the edges of the filters and the like from above. It is not necessary, and the cost of the cartridge 6 can be easily reduced. Furthermore, since the radial width of the lower edge of the lower edge of the cartridge case 8 is increased by the projection length of the flange 36, the protrusion is projected downward from the lower end surface of the cartridge case without the flange 36. Therefore, the degree of freedom in selecting the shape, size, arrangement, number, and the like of the protrusions is increased, and an optimum protrusion can be easily obtained.

A water preparation cartridge 6 which is connected to the upper pipe 5 so that the upper part thereof can be freely inserted and removed, and which is mounted in the main body container 2. In the skin water preparation device configured to be sprayed, the cartridge 6 is provided with a projection 37 protruding downward from the raw water suction port 9 at the lower portion, and the projection 37 forms the raw water at the bottom surface 2a of the main body container 2 and the lower portion of the cartridge 6. Since a predetermined gap is secured between the suction port 9 and the suction port 9, a remarkable effect of reliably preventing poor ejection of skin water due to excessive approach or contact of the cartridge 6 with the bottom surface 2a of the main body container 2 is achieved.
[0031]
The cartridge 6 includes a cylindrical cartridge case 8, a bottom filter 10 provided at a lower end opening of the cartridge case 8, a water conditioning ion exchange resin housed on the bottom filter 10 of the cartridge case 8, and a cartridge 6. An intermediate filter 12 provided on the ion-exchange resin layer 11 of the case 8; an inward flange 36 provided at a lower end opening edge of the cartridge case 8; The protrusion 37 of the cartridge case 8 protrudes, and the radial width of the lower end opening edge of the cartridge case 8 is increased by the protrusion length of the flange 36. The degree of freedom in selecting the shape, size, arrangement and number of the projections 37 is increased as compared with the case where the projections 37 are projected. In addition, the optimum projection 37 can be easily obtained, and the flange 36 plays a role of positioning and retaining the bottom filter 10, so that the bottom filter 10 can be properly attached to the lower end opening of the cartridge case 8. The bottom of the case 8 can be easily formed.
[0032]
In addition, the inner hole 8a of the cartridge case 8 is formed as a tapered hole that is narrowed downward, and the filters 10 and 12 are moved to a predetermined depth position (mounting position) in the cartridge case 8 only by the size of the filter outer shape. For example, the cartridge case 8 above the bottom filter 10 is vertically partitioned by a plurality of intermediate filters 11a and 12 with a plurality of intermediate filters 11a and 12, and each partition space contains a different type of water exchange ion exchange resin. In the case of obtaining the cartridge case 8, it is not necessary to provide multiple steps on the inner peripheral surface of the cartridge case 8 for locking the edges of the filters 11a and 12 from above. Simply by fitting, each of the filters 11a and 12 can be fitted and fixed at a predetermined depth position (attachment position). The cost of the cartridge case 8 can be easily reduced, and the outer shape of the cartridge case 8 is also formed to be a tapered hole as the inner hole 8a of the cartridge case 8 is formed as a tapered hole. The cartridge 6 can be easily moved in and out of the upper end opening 3 of the container 2, and the cartridge replacement operation can be easily performed as compared with the conventional case.
[0033]
In addition, a suction pipe connecting member 21 made of an elastic material and having a shaft hole 21a at the center thereof, which is fitted into the upper end opening of the cartridge case 8 and insertably holds the suction pipe 5 of the spraying device 4, is provided. Alternatively, by directly fitting the upper part of the cartridge case 8 to the outside of the suction pipe 5 of the spraying device 4, the upper part of the cartridge 6 is connected to the suction pipe 5 of the spraying device 4 so as to be freely inserted and removed. In the former case, there is no need to adjust the thickness of the cartridge case 8 to the size of the suction pipe 5 of the spraying device 4, and the cartridge for the household skin water preparation device having a large raw water capacity of the main body container 2. In the latter case, the thickness of the cartridge case 8 can be reduced in accordance with the size of the suction pipe 5 of the spraying device 4, and the amount of raw water stored in the main body container 2 is small. Car for small skin water preparation machine for The ridge 6 can be easily obtained.
