By releasing the screwing, the illustrated upper portion of the water channel 70 is opened, and the cartridge 50 can be detached.

  As shown in FIG. 2, a plurality of raised portions 12 e are formed at the bottom of the downstream side of the water channel 70. As shown in FIG. 2, by placing the cartridge 50 on the raised portion 12 e, cold water and hot water are diffused into the water channel 70. Although not shown, a plurality of positioning rib portions that engage the outer peripheral surface of the cartridge 50 and position the cartridge 50 at the center position of the water channel 70 are formed on the inner peripheral surface of the grip portion 12.

  3A and 3B show a state before the cartridge 50 is attached to the shower head 10, and the lid member 61 can be attached to and detached from the outlet member 55 of the cartridge 50 as shown in FIG. Fitted.

  The cartridge 50 includes a cartridge case 51 having a bottomed cylindrical shape. A plurality of slit portions 51 a are formed on the bottom wall of the cartridge case 51. As shown in FIG. 3B, a cylindrical valve chamber 51 b communicating with the slit portion 51 a is formed at the center of the bottom wall of the cartridge case 51. The valve chamber 51 b communicates with the opening 51 c at the upstream end of the inner pipe 53. The opening 51c is an example of an inflow port, and the inner pipe 53 is an example of a water pipe.

  As shown in FIGS. 2 and 3B, a duckbill valve 52 made of an elastic material such as rubber that functions as a check valve is disposed in the valve chamber 51b. The tip 52b of the duckbill valve 52 is broken into two, and the tip 52b is elastically contacted.

  As shown in FIGS. 2 and 3 (b), a cylindrical inner tube 53 whose lower part is integrated with the valve chamber 51b is disposed at the axial center of the cartridge case 51. A cylindrical outlet member 55 is fitted into the downstream end portion of the cartridge case 51, and the downstream end portion of the inner tube 53 is fitted therein, and the downstream end portions of the outlet member 55 and the inner tube 53 are inserted therein. The discharge port 53a is in communication. The discharge port 53a is an example of a discharge unit.

  The inner tube 53 is provided with a plurality of rows of communication holes 53c in the circumferential direction and in the length direction in a region on the downstream end side of the center portion. The groups of communication holes 53c in each row are arranged at a predetermined pitch (ie, equal pitch). The pitch may be an unequal pitch, but an equal pitch is more preferable.

  Further, a cylindrical medicine container 54 is defined between the inner tube 53 and the valve chamber 51 b and the cartridge case 51. In the present embodiment, the medicine container 54 is formed in a cylindrical shape, but is not limited to a cylindrical shape, and may be a rectangular tube shape or a polygonal tube shape. A solid water-soluble medicine 100 (that is, a shower head cosmetic) is contained (filled) in the storage space of the medicine storage portion 54. As shown in FIGS. 2 and 3 (b), the water-soluble drug 100 is not dissolved in the initial state, and the downstream end of the drug 100 is the communication hole 53c located on the most upstream side among the plurality of communication holes 53c. It arrange | positions so that it may become the same height as the height of a lower end position. As shown in FIG. 2 and FIG. 3B, the boundary line K between the non-communication portion 102 and the communication hole 53c (communication portion) is the same height as the height of the lower end position of the communication hole 53c located on the most upstream side. become. In this embodiment, the water-soluble drug 100 is filled up to the boundary line K in the initial state.

A space 101 is formed between the downstream end of the medicine 100 and the upper end of the outlet member 55. The storage space of the medicine container 54 is an example of a storage chamber.
In the present embodiment, for example, a moisturizing agent including a moisturizing component is used as the drug 100. This medicine 100 is dissolved by cold water and hot water taken in through the communication hole 53c of the inner tube 53 to generate a moisturizing liquid. Then, the moisturizing liquid flows out of the cartridge 50 through the outlet member 55.

  Here, the communication hole 53c is an example of a communication part. Further, in the inner tube 53, the remaining portion that does not have the communication hole 53 c (communication portion) and that faces the storage space of the medicine storage portion 54 filled with the water-soluble medicine 100 is a non-communication portion. 102.

  As shown in FIGS. 2 and 3B, a net-like strainer 57 is disposed between the illustrated upper end portion (that is, the downstream end portion) of the inner pipe 53 and the outlet member 55. The strainer 57 is made of a wire mesh or the like. For this reason, the strainer 57 has a large number of fine holes. The strainer 57 separates the solid drug 100 from the solid state drug 100 and keeps the particles flowing out from the communication hole 53c from flowing out to the head part 11 side. The strainer 57 has an inverted cup shape as a whole, and bulges toward the downstream side of the upper end in the figure.

(Operation of the embodiment)
Next, the operation of the shower head and cartridge 50 configured as described above will be described.

  When using a shower that does not contain moisturizing liquid, the second operating member 48 is pushed in as shown in FIG. In this way, the flow channel 71 on the water passage gap 12c side of the water channel 70 is opened, and the flow channel 72 on the inner tube 53 side is closed, so that cold water or hot water is passed through the shower hose. It flows into the flow path 71 of the head portion 11 through the gap 12 c and is discharged from the water spray hole 16. In this case, since the flow path 72 on the downstream side of the inner pipe 53 is closed, the duckbill valve 52 is not opened, and water does not flow into the inner pipe 53 of the cartridge 50. Therefore, in this state, even if the duckbill valve 52 is closed by its own elasticity and the water pressure in the inner pipe 53 becomes higher than the water pressure on the upstream side of the duckbill valve 52, the pressure difference is relative to the duckbill valve 52. Acting in the valve closing direction.

Therefore, it is possible to prevent the moisturizing liquid in the inner pipe 53 from flowing backward to the shower hose side outside the shower head 10.
When using the shower containing a moisturizing liquid, the pressing part 45a of the 1st operation member 45 shown in FIG. 1, FIG. 2 is pressed. For this reason, the flow path 72 is opened. Accordingly, the cold water or hot water not only flows from the water passage gap 12c to the flow path 71 side, but also the flow path 72 upstream of the duckbill valve 52 is opened, so that the duckbill valve 52 in FIG. It flows into the inner tube 53 of the cartridge 50.

  The cold water or hot water that has flowed into the inner pipe 53 flows into the medicine container 54 through the communication hole 53 c of the inner pipe 53. The water that has flowed into the medicine container 54 dissolves the downstream end of the medicine in the medicine container 54 and becomes a moisturizing liquid. Then, the moisturizing liquid flows out from the communication hole 53 c into the inner pipe 53 and flows into the flow path 72 from the outlet member 55 through the strainer 57. The moisturizing liquid in the flow path 72 is mixed with cold water or hot water flowing in the flow path 71 from the water passage gap 12 c on the downstream side of the switching unit 20 to become a diluted moisturizing liquid. Then, the diluted moisturizing liquid is discharged from the sprinkling holes 16.

  The water-soluble drug 100 facing the region that becomes the non-communication portion 102 in the inner tube 53 is gradually moved to the upstream side because the downstream end thereof is dissolved. However, if the portion of the drug 100 facing the space 101 moves to the lower end side of the drug container 54 in the illustration of FIG. 2 by dissolution, the cold water or hot water that has entered the drug container 54 through the communication hole 53c is the downstream end of the drug 100. The turbulent flow in the space where the face is exposed, or the reduced drug 100 is lifted. For this reason, even if the hole is not formed in the wall of the valve chamber 51b, the medicine 100 is appropriately dissolved and flows out from the communication hole 53c.

  As described above, a normal shower that does not include the moisturizing liquid and a shower that includes the moisturizing liquid can be obtained by the selection operation of the first and second operation members 45 and 48. In this case, the inner diameter of the inner tube 53, the opening size and number of the communication holes 53c, the arrangement position, and the like are set so that a moisturizing liquid with an appropriate concentration can be obtained. If it does in this way, medicine 100 will be scraped off little by little by cold water or warm water which flowed in medicine storage part 54, and will be dissolved instantly.

  In the present embodiment, the outer diameter of the inner pipe 53 is the same except for the valve chamber 51b portion. Further, the inner diameter of the medicine container 54 is the same in the entire length direction. Therefore, in the non-communication portion 102 of the same outer diameter portion of the inner tube 53, for the shower head between the inner peripheral surface of the cartridge 50 forming the medicine container 54 and the non-communication portion 102 of the inner tube 53 (water pipe). The cross-sectional area in the cosmetic filling space has a region that is the same in the direction in which the axis of the inner tube 53 extends.

  And in the area | region where the cross-sectional area of the said filling space is the same in the direction where the said axial center extends, since the area which touches the cold water or warm water of the cosmetics for shower heads is the same, the temperature of water and the flow rate of water are the same Under the conditions, the rate of dissolution of the shower head cosmetic can be made the same. That is, the showerhead cosmetic can be stably and uniformly eluted in cold water or warm water.

  Further, the cold water or the hot water stays in the inner pipe 53 and the space 101 in a state where the cold water or the hot water is not flowing. In this case, the cold water or hot water in the space 101 touches only the downstream end of the water-soluble drug 100. For this reason, only the downstream end of the water-soluble drug 100 swells.

  Therefore, when the cartridge is reused later, even if the medicine stored in the medicine storage section 54 is stored in water or in the shower head for a long time, the water flow in the medicine storage section in the cartridge is reduced. Can be suppressed.
