  However, the shower head described in this document is provided with a first flow path through which only raw water passes in the cartridge. For this reason, the space which accommodates a chemical | medical agent cannot be taken large. Therefore, it is conceivable to provide only a space for accommodating the medicine in the cartridge. In this case, it is difficult to seal so that the solution in which the drug is dissolved does not leak when the flow path or the switching mechanism already provided in the shower head 10 is used to switch only to the raw water.

  This invention was made paying attention to the subject which exists in such a prior art, and the objective is to enlarge the storage space of the chemical | medical agent in a cartridge, and the flow path and switching provided in the shower head. An object of the present invention is to provide a shower head and a cartridge built into the shower head for making it difficult for the drug solution to leak even if the mechanism is used.

  In order to achieve the above object, the present invention provides a shower head comprising a head part for spraying a liquid and a grip part separable from the head part, wherein the grip part contains a drug dissolved in the liquid. A cartridge housing portion that detachably accommodates the accommodated cartridge; the cartridge housing portion has a shape that defines a communication path with the cartridge to be accommodated; and the head portion includes the communication portion. A supply path communicating with the path, a solution inflow path for allowing a solution in which the medicine in the cartridge is dissolved to flow in, and a first state in which the solution inflow path is blocked from the supply path; and the supply path And a switching means for switching between the second state and the second state communicated in a sealed state.

  As a result, when the solution in which the medicine stored in the cartridge is dissolved is not sprayed, the liquid passes through the communication path defined between the cartridge and the flow path used for spraying the liquid is formed inside the cartridge. There is no need to form. Therefore, it is possible to secure a large space for accommodating inside the cartridge. In addition, since the head unit is provided with switching means for switching between blocking or communicating between the solution outflow path through which the solution from the cartridge flows and the supply path of the head section, the head section switching means is used. However, switching between the spraying of the liquid and the spraying of the solution can be performed in a state in which leakage is difficult according to the user's application.

  In the above-described configuration, the solution inflow path is formed at a predetermined angle with respect to the grip portion, and the switching unit blocks or communicates the solution inflow path with the supply path by movement in the axial direction. A switching moving body and an operation unit integrated with the switching moving body are provided. Thereby, it is possible to easily switch between the case of spraying the solution in which the medicine in the cartridge is dissolved and the case of spraying only the liquid with a simple configuration.

  In the above configuration, the head portion includes a positioning member for holding the first state in which the solution inflow path is blocked from the supply path and the second state in communication with the supply path. It is provided. Thereby, a 1st state and a 2nd state can be hold | maintained more reliably.

  In order to achieve the above object, the present invention includes a head portion for spraying a liquid and a grip portion that can be attached to and detached from the head portion, and the grip portion includes a cartridge that contains a medicine to be dissolved in the liquid. A cartridge housing part that is detachably incorporated and has a shape that defines a communication path between the cartridge and the cartridge to be stored is provided, and the head part includes a supply path that communicates with the communication path, and a medicine in the cartridge A solution inflow path through which the solution in which the solution is dissolved is formed, and is switched between a first state in which the solution inflow path is blocked from the supply path and a second state in which the supply path is communicated in a sealed state A cartridge that can be incorporated in a shower head provided with a switching means, and contains a medicine that dissolves in the liquid and takes in a liquid that is supplied to the medicine And a solution outflow channel that communicates with a solution inflow path of a shower head that allows the solution in which the drug is dissolved to flow, and the intake channel has the above-described configuration when the cartridge is disposed in the cartridge housing portion. It is formed so that a liquid may flow into the medicine from the communication path, and the solution outflow channel is formed at a position where the solution can be communicated with the solution inflow path. As a result, even if the flow path used for spraying the liquid is not formed inside the cartridge, it is used as a cartridge when switching between spraying the solution in which the medicine contained in the cartridge is dissolved and spraying only the liquid. be able to.

  In the above configuration, the intake flow path is provided with a check valve, and the check valve is configured so that the solution outflow path is not in communication with the supply path of the head unit. When the liquid does not flow into the medicine and the solution outflow channel communicates with the supply path of the head unit, the liquid flows into the medicine. Thereby, since the liquid is supplied to the medicine only when the solution in which the medicine is dissolved is sprayed, it is possible to prevent the medicine from flowing back and mixing into the supply path.

  In the above-described configuration, an outlet member that can be inserted into the head portion is provided, and the outlet member is provided with an inner hole that constitutes the solution outflow channel, and the insertion support portion is fitted into the inner hole. The lid member provided with is detachably attached.

Next, the operation of the shower head configured as described above will be described with reference to FIGS.
The shower head 10 of this embodiment is connected to water supply via a shower hose. It is also possible to use hot water instead of water. Further, when spraying only water, the shower head 10 of the present embodiment has a state in which the first shaft 40 is positioned on the through-hole 15d side (supplying a solution inflow path) as shown in FIGS. Used in the first state of being cut off from the road). Further, when spraying a moisturizing agent in which the medicine in the cartridge 50 is dissolved, the shower head 10 places the first shaft 40 on the through hole 15e side (with respect to the central axis of the shower head 10) as shown in FIG. Then, it is used in a state of being located on the opposite side of the through-hole 15d (second state in which the solution inflow path communicates with the supply path).

  First, the case where only the water is sprayed using the shower head 10 of this embodiment is assumed. In this case, as shown in FIG. 2, the second operating member 48 is pushed into the center side of the shower head 10, and the first operating member 45 is used in a state of protruding from the head body 15. At this time, as shown in FIG. 6, the cylindrical body 35a of the positioning member 35 is engaged with the groove portion 40a of the first shaft 40, and the first shaft 40 closes the space between the through hole 32a. Further, the outflow of water from the cartridge 50 to the inner hole 15c side (space 72 side) of the head body 15 is prevented.

  In this state, water is supplied to the supply hole 12b of the grip part 12 of FIG. 2 through the shower hose. Water flows from the supply hole 12b into the flow path 70 between the grip portion 12 and the cartridge 50 via the periphery of the raised portion 12e and the periphery of the positioning rib portion 12f.

  The water flowing through the flow path 70 passes through the space 71 between the outlet member 55 of the cartridge 50 and the head main body 15 and the space 72 where the tip of the positioning member 35 is located, and passes through the inner hole 15 c of the head main body 15. Flowing. Then, this water passes through the microbubble generating member of the head main body 15 and becomes water in which microbubbles are mixed, and is sprayed from the watering holes 16 a of the watering member 16.

  In this case, since the space between the first shaft 40 and the through hole 32 a is closed, the duckbill valve 52 is not opened, and water does not flow into the cartridge inner pipe 53 of the cartridge 50.

  Next, the case where the moisturizing liquid in which the medicine is dissolved is sprayed will be described. In this case, the switching unit 20 is switched to the second state so that the second operation member 48 protrudes from the head body 15. Specifically, the pressing portion 45 a of the first operating member 45 is pressed toward the center of the shower head 10. Thereby, the front end of the cylindrical body 35a of the positioning member 35 is pressed from the first shaft 40 and is disengaged from the groove 40a.

  When the first shaft 40 further moves in the center direction of the shower head 10, the seal ring 41 is detached from the through hole 32a of the flow path forming member 30, and a space is defined between the first shaft 40 and the through hole 32a. The Further, when the positioning member 35 faces the groove portion 40b, the positioning member 35 is pressed toward the first shaft 40 (upward in the drawing) by the spring 36 and is fitted into the groove portion 40b. As a result, as shown in FIG. 8, the second operation member 48 protrudes from the head main body 15, and the first operation member 45 is pushed into the head main body 15.

  In this case, water sequentially passes from the supply hole 12b of the grip portion 12 shown in FIG. 2 to the periphery of the raised portion 12e and the periphery of the positioning rib portion 12f to flow between the grip portion 12 and the cartridge 50. It flows to the road 70. The water that has flowed into the flow path 70 flows through a space 71 between the outlet member 55 of the cartridge 50 and the head body 15 and a space 72 where the tip of the positioning member 35 is located.

  Further, as shown in FIG. 8, since the space between the first shaft 40 and the through hole 32a is partitioned and can be circulated, the duckbill valve 52 of FIG. Water flows into the inner pipe 53. The inflowing water is supplied to the medicine container 54 through the communication hole 53 c of the cartridge inner tube 53. Here, the water dissolves the medicine in the medicine container 54 and becomes a moisturizing liquid. The moisturizing liquid flows into the stepped hole of the outlet member 55 through the filter member 57.
