For example, a shower head for removing residual chlorine has been proposed (see, for example, Patent Document 1). The shower head described in Patent Document 1 incorporates a removable water purification cartridge. The cartridge is constituted by a pipe arranged at the center thereof, and a purification processing section in which a purification agent is filled between a first flow path through which only raw water passes and a case body and a pipe of the first flow path. The 2nd flow path which consists of. The purification treatment unit purifies the raw water, removes residual chlorine contained in the raw water, and generates purified water. Raw water and purified water are selectively introduced from the cartridge into the shower head, and the raw water and the purified water are switched according to the operation of the knob.

JP-A-11-333328

The water purification cartridge in the shower head described in Patent Document 1 is provided with a first flow path through which only raw water passes. For this reason, in the purification process part arrange | positioned around it, the space which accommodates the chemical | medical agent for purification | cleaning cannot be enlarged. In view of this, it is conceivable to omit the first flow path and provide only the purification treatment section filled with the purification chemical in the cartridge. In this case, when switching to supplying only raw water using the flow path already provided in the shower head, sealing is performed so that the solution in which the drug is dissolved does not leak into the raw water from the cartridge. It is difficult.

This invention was made paying attention to the subject which exists in such a prior art, The objective is making the storage space of the chemical | medical agent large in a cartridge, and using the flow path provided in the shower head. Even so, an object of the present invention is to provide a shower head for making it difficult for a drug solution to leak and a cartridge built in the shower head.

To achieve the above object, according to the first aspect, there is provided a shower head including a head part for spraying a liquid and a grip part detachably attached to the head part. The grip portion includes a cartridge housing portion in which a cartridge containing a medicine is detachably incorporated, and the medicine is dissolved in the liquid to generate a solution. The inner wall of the cartridge housing portion defines a communication path with the cartridge. The head portion includes a supply path that communicates with the communication path and a solution inflow path through which the solution flows. The shower head includes a switching unit that switches the solution inflow path between a first state that is blocked from the supply path and a second state that is communicated with the supply path.

Thereby, when the solution in which the medicine accommodated in the cartridge is dissolved is not sprayed, the liquid passes through the communication path defined between the inner wall of the cartridge accommodating portion and the cartridge. Therefore, it is not necessary to form a flow path used for spraying the liquid inside the cartridge. Therefore, a large space can be secured for accommodating the medicine inside the cartridge. In addition, the head unit is provided with a switching unit that incorporates the cartridge and switches between blocking or communicating between the solution outflow path through which the solution from the cartridge flows and the supply path of the head unit. Therefore, it is possible to perform the switching between the spraying of the liquid and the spraying of the solution in a state in which it is difficult to leak while utilizing the switching unit of the head unit.

In the above-described configuration, the solution inflow path extends at a predetermined angle with respect to the grip part, and the switching unit moves along the axial direction, thereby causing the solution inflow path to move relative to the supply path. A switching moving body that is blocked or communicated, and an operation unit integrally connected to 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 unit includes a holding member for holding the solution inflow path in the first state and the second state, respectively. Thereby, a 1st state and a 2nd state can be hold | maintained more reliably.

Also, according to the second aspect, a cartridge that can be built in a shower head is provided. The shower head includes a head part for spraying liquid and a grip part detachably attached to the head part. The grip portion includes a cartridge housing portion configured to detachably incorporate the cartridge. The inner wall of the cartridge housing portion defines a communication path with the cartridge. The head portion includes a supply path communicating with the communication path and a solution inflow path. The shower head includes a switching unit that switches the solution inflow path between a first state in which the solution inflow path is blocked from the supply path and a second state in which the solution inflow path is communicated with the supply path. The cartridge contains a drug. The drug is dissolved in the liquid to form a solution. The cartridge has an intake channel that takes in the liquid from the communication path so as to communicate with the communication path and supply the liquid to the medicine when the cartridge is disposed in the cartridge housing portion. . The cartridge also includes a solution outflow channel that communicates with the solution inflow path of the showerhead and supplies the solution to the solution inflow path when the cartridge is disposed in the cartridge housing portion. This cartridge can be used so as to switch between spraying the solution in which the medicine contained in the cartridge is dissolved and spraying only the liquid without forming a flow path used for spraying the liquid inside the cartridge. .

In the above-described configuration, the cartridge has a check valve disposed in the intake flow path, and the check valve is used when the solution outflow path is not in communication with the supply path of the head unit. Is configured such that when no liquid flows into the drug and the solution outflow channel communicates with the supply path of the head unit, the liquid flows into the drug. Thereby, since the liquid is supplied to the drug only when the solution in which the drug is dissolved is sprayed, it is possible to avoid the drug from flowing backward in the intake channel and mixing into the supply channel.

In the above-described configuration, the cartridge includes an outlet member that can be inserted into the head portion, and the outlet member has a hole that forms the solution outflow channel, and the cartridge is fitted into the hole. A lid member having an insertion support portion is detachably attached. Thereby, since the hole of the outlet member can be prevented from being deformed by the insertion support portion of the lid member, a gap is hardly formed between the outlet member and the head portion for accommodating the outlet member, and the drug is dissolved. The solution can be made difficult to leak.

In the above configuration, the drug is a humectant. Thereby, a moisturizing agent can be sprayed from the shower head.

ADVANTAGE OF THE INVENTION According to this invention, while increasing the storage space of the chemical | medical agent in a cartridge, even if the flow path provided in the shower head is utilized, the shower head for making it difficult to leak the chemical | medical solution, and the cartridge built in this Can be provided.

On the other hand, the second end portion (the right side in FIG. 6) having a large outer diameter of the first shaft 40 is held in the second through hole 15 e of the head body 15. A seal ring 46 is disposed between the first shaft 40 and the second through hole 15e. The second end portion of the first shaft 40 is integrally connected to the second operation member 48 via a press-fit boss 47.

Next, the operation of the shower head configured as described above will be described with reference to FIGS.

The shower head 10 of the present embodiment is connected to the water supply via a shower hose. It is also possible to use hot water instead of water. Moreover, when spraying only water, the shower head 10 of this embodiment is the state which moved the 1st shaft 40 to the direction approaching the 1st through-hole 15d, as shown in FIG.2 and FIG.6 ( The first state where the solution inflow path is blocked from the supply path is used. When spraying the moisturizing agent (solution) in which the medicine in the cartridge 50 is dissolved, the shower head 10 moves the first shaft 40 away from the first through hole 15d (shower) as shown in FIG. It is used in a state in which the head 10 is moved to the opposite side of the first through hole 15d across the central axis of the head 10 (second state in which the solution inflow path communicates with the supply path).

First, it is assumed that only the water is sprayed using the shower head 10 of the present embodiment. In this case, as shown in FIG. 2, the second operating member 48 is pushed toward the center 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 35 a of the holding member 35 is engaged with the groove portion 40 a of the first shaft 40. In this state, the first shaft 40 (seal ring 41) closes the space between the through hole 32a and prevents the outflow of water from the cartridge 50 toward the inner hole 15c (space 72) of the head body 15. Yes.

In this state, water is supplied to the supply hole 12b of the grip portion 12 in 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 body 15 and the space 72 including the tip of the holding member 35, and then flows through the inner hole 15 c of the head body 15. This water passes through the microbubble generating member of the head main body 15, 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 32a is closed, the duckbill valve 52 is not opened, and water does not flow into the cartridge inner tube 53 of the cartridge 50.

Next, a case where a moisturizing liquid (solution) in which a drug 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 | tip of the cylinder 35a of the holding member 35 remove | deviates from the groove part 40a, when the 1st shaft 40 is pressed.

Further, when the pressing portion 45a of the first operating member 45 is moved toward the center of the shower head 10, the seal ring 41 is detached from the through hole 32a of the flow path forming member 30, and the first shaft 40 and the through hole 32a A space is formed between the two. Further, when the holding member 35 is moved until it faces the groove portion 40b, the holding 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 to enter the second state.

An inner wall of the hollow portion 12 c defines a flow path 70 (communication path) between the cartridge 50 and the inner wall. The cartridge 50 is formed with a slit 51a and a recess 51b (take-in channel) through which water that has flowed into the hollow portion 12c flows. A flow path forming member 30 that forms a space 71 communicating with the flow path 70 is disposed in the inner hole 15 c of the head portion 11 of the shower head 10. A first shaft 40 that moves along the axial direction of the through hole 32 a is disposed in the through hole 32 a of the flow path forming member 30. When the first shaft 40 is moved in a direction approaching the first through hole 15d, the space between the first shaft 40 and the through hole 32a is closed, and the flow path 70 and the

spaces

71 and 72 are interposed. Water flows into the head part 11. When the first shaft 40 is moved away from the first through hole 15d, the space between the first shaft 40 and the through hole 32a is opened, and the moisturizing liquid in which the medicine is dissolved from the cartridge 50 is the head. Supplied to the unit 11. Thereby, the inside of the cartridge 50 can be used as a large space for accommodating the solution in which the medicine is dissolved. Further, since the cartridge 50 is built in, the switching unit 20 is provided in the head unit 11 disposed above the cartridge 50, and the leading end of the cartridge 50 is fitted to the switching unit 20, so that the switching unit 20 is used with a structure that is difficult to leak. However, it is possible to switch between spraying only water and spraying the moisturizing liquid in which the drug is dissolved.

(2) The shower head 10 according to the present embodiment includes the flow path forming member 30 having the engaging protrusion 33 that engages with the holding member 35. The holding member 35 is selectively aligned with the groove 40 a and the groove 40 b of the first shaft 40 and is urged toward the first shaft 40 by the spring 36. Thereby, the 1st state which opens the space between the 1st shaft 40 and the through-hole 32a, and the 2nd state which obstruct | occludes can be hold | maintained more reliably.

(3) The replaceable cartridge 50 built in the shower head 10 of the present embodiment contains a moisturizing agent as a medicine. For this reason, it can replace with the spraying only with water, and can moisturize easily.

(4) In the cartridge 50 of the present embodiment, a duckbill valve 52 is disposed on the upstream side of the medicine container 54. When the switching unit 20 of the shower head 10 is switched to the second state and a space is formed between the first shaft 40 and the through hole 32a and can be circulated, the duckbill valve 52 is opened, Water flows into the cartridge inner tube 53 of the cartridge 50. Therefore, when the outflow side of the cartridge 50 is closed, that is, in the first state, the duckbill valve 52 is closed and no more water flows into the medicine container 54. For this reason, it is possible to prevent the moisturizing liquid in which the drug is dissolved from flowing back into the shower hose.
