The present invention relates to a shower head for spraying a liquid and to be contained therein.

Since the tap water contains residual chlorine, there is a case where the water is removed by removing the residual chlorine for beauty or health. For example, a shower head capable of removing residual chlorine has been proposed (for example, refer to Patent Document 1). The shower head described in Patent Document 1 is provided with a detachable water purifier. The crucible includes a first flow path formed of a pipe body disposed at a center thereof and passing only raw water, and a purification processing unit filled with a cleaning agent between the casing and the pipe body of the first flow path. The second runner. The purification treatment unit purifies the raw water to remove residual chlorine contained in the raw water to generate purified water. The raw water and the purified water are selectively introduced into the shower head from the crucible, and the raw water and the purified water are switched in accordance with the operation of the handle portion.

Patent Document 1: Japanese Laid-Open Patent Publication No. 11-333328

The clean water tank in the shower head described in Patent Document 1 is provided with a first flow passage through which only raw water passes. Therefore, it is impossible to enlarge the accommodation space of the purification drug in the purification processing unit disposed around the inside. Then, it is considered that in the crucible, the first flow path is omitted, and only the purification processing unit filled with the purification chemical is provided. In this case, when the flow path provided by the shower head is used to supply only the raw water and is switched, it is quite difficult to seal the solution so that the solution after the drug is dissolved does not leak out into the raw water.

The present invention focuses on the problems of the above-mentioned prior art, and its purpose is to provide a The storage space of the medicinal agent in the sputum is enlarged, and even if the flow path provided by the shower head is used, the shower head which is not easy to leak the solution of the medicinal agent and the inside can be installed therein.

In order to achieve the above object, a first aspect of the present invention provides a showerhead provided with a head for spraying a liquid and a handle portion detachably attached to the head. The handle portion is provided with a sputum accommodating portion detachably containing a sputum containing a drug, and the drug is dissolved in the liquid to form a solution. The inner wall of the weir receiving portion is separated from the weir by a communication path. The head has a supply passage that communicates with the communication path and a solution inflow path for the solution to flow in. The shower head includes a switching unit that switches the solution inflow path to a first state in which the supply path is blocked and a second state in which the supply path is connected.

Thereby, when the solution contained in the sputum-dissolving agent is not sprayed, the liquid passes through a communication path which is partitioned between the inner wall of the dam receiving portion and the cymbal. Thus, it is not necessary to form a flow path for spraying the liquid inside the crucible. Thereby, a large space for accommodating the medicine can be secured inside the crucible. Further, the inside is provided with a crucible, and a solution outflow path for the solution from the crucible is provided in the head, and the switching portion switches the blocking or communication with the supply passage of the head. Therefore, the switching portion of the head can be utilized, and the spraying of the liquid and the spraying of the solution can be performed in a state where the leakage is not easily performed in accordance with the use of the user.

In the above configuration, the solution inflow path extends at a specific angle with respect to the handle portion; the switching portion is configured to: switch the moving body to move in the axial direction, thereby flowing the solution into the path resistance with respect to the supply path And the operation unit is integrally coupled to the switching moving body. Thereby, it is possible to easily switch between the case where the solution of the sprayed sputum agent is dissolved and the case where only the liquid is sprayed, with a simple structure.

In the above configuration, the head portion includes a holding unit that holds the solution inflow path in the first state and the second state. Thereby, the first state and the second state can be more reliably maintained.

Further, the second aspect provides a crucible that can be built in the showerhead. The shower head is provided with a head for spraying a liquid, and a handle portion detachably mounted to the head. The handle portion is provided with a weir receiving portion configured to detachably house the weir. The inner wall of the weir receiving portion is separated from the weir by a communication path. The head is provided with a supply passage that communicates with the communication path, and a solution inflow path. The shower head includes a switching unit that switches the solution inflow path to a first state in which the supply path is blocked and a second state in which the supply path is connected. This tether contains the medicament. The drug is dissolved in the liquid to form a solution. The crucible is provided with an introduction flow path that communicates with the communication path when the crucible is disposed in the crucible accommodation portion, and the liquid is introduced from the communication path to supply the liquid to the medicine. The crucible is further provided with a solution outflow channel, and when the crucible is disposed in the crucible receiving portion, the solution is connected to the solution inflow path of the shower head to supply the solution to the solution inflow path. The escapement is such that the flow path for spraying the liquid is not formed inside the crucible, and the solution sprayed with the liquid contained in the crucible can be switched and the liquid-only spray can be used.

In the above structure, the crucible has a check valve disposed on the introduction flow passage; the check valve is configured such that when the solution outflow passage is not connected to the supply passage of the head, the liquid does not flow into the medicament. And when the solution flows out of the flow path to the supply passage of the head, the liquid will flow into the medicament. Thereby, since the liquid is supplied to the medicine only in the case of the solution after the spray agent is dissolved, it is possible to avoid introduction into the flow path, and the medicine flows back into the supply path.

In the above structure, the crucible is provided with an outlet assembly insertable into the head, the outlet assembly having a hole constituting the outflow passage of the solution, the crucible being detachably mounted with the fitting A cover assembly for inserting the support into the hole. Thereby, since the hole deformation of the outlet assembly can be avoided by the insertion support portion of the cap assembly, it is difficult to create a gap between the outlet member and the head accommodating the same, so that the solution after the drug is dissolved is less likely to leak.

In the foregoing structure, the agent is a humectant. In this way, the moisturizer can be sprayed from the shower head.

According to the present invention, it is possible to provide a storage head which can enlarge the accommodating space of the sputum, and even if the flow path provided by the shower head is used, the shower head which can prevent the solution of the drug from leaking and the inside can be installed therein.

The communication hole 32b is in communication with the housing portion 31a of the solution inflow portion 31. Further, as shown in FIG. 7(b), the mixed flow path forming portion 32 is formed with a ring groove 32c around the through hole 32a.

Further, as shown in FIG. 7(a), a pair of concave portions are formed at both side faces of the engagement projection 33, and a holding hole 33a is formed at the center of the engagement projection 33. At a central portion of the bottom surface of the holding hole 33a, the projection 33b shown in Fig. 6(a) is formed to protrude toward the flow path fitting portion 34.

As shown in FIG. 7(a), the holding hole 35 of the engaging projection 33 is provided with a holding unit 35. The holding assembly 35 is a cylindrical body 35a having a dome shape at the front end and extended on both sides of the cylindrical body 35a. A belt-shaped pair of engaging assemblies 35b are formed. The end edge of the engaging member 35b of the holding unit 35 is engaged with the concave portion on both side surfaces of the engaging projection 33, and is slidably engaged with the cylindrical body 35a along the axial direction of the flow path forming member 30. Further, the cylindrical body 35a of the holding unit 35 is inserted into the holding hole 33a.

The first shaft member 40 is a stepped cylindrical unit, and its outer diameter is gradually reduced from the second end portion close to the second through hole 15e toward the first end portion close to the first through hole 15d. The groove portions 40a and 40b are formed in a part of the outer circumference of the first shaft member 40. The grooves 40a, 40b are sized to be integrated into the front end of the cylinder 35a of the holding assembly 35.

The outer diameter of the first shaft member 40 between the groove portions 40a and 40b is set to be smaller than the inner diameter of the through hole 32a of the flow path forming member 30. Then, a space is formed between the through hole 32a and the first shaft member 40 to allow the liquid to flow therein. Further, a seal ring 41 is fitted around the center portion of the first shaft member 40. When the seal ring 41 is in contact with the through hole 32a of the mixed flow path forming portion 32, the space between the through hole 32a and the first shaft member 40 is blocked. Thereby, the space in which the accommodating portion 31a of the flow path forming member 30 and the front end of the holding unit 35 are disposed (the space between the flow path forming member 30 and the inner hole 15c of the head body 15) 72 is blocked.

Further, the first end portion (the left side in FIG. 6) having the small outer diameter of the first shaft member 40 is formed with a screw hole extending in the axial direction of the first shaft member 40. The second shaft member 42 having the stepped hole is held in the first through hole 15d of the head main body 15. A seal ring 43 is fitted to the outer circumference of the second shaft member 42. The stepped hole of the second shaft member 42 has a small inner diameter at the first end portion (the left side of FIG. 6) and a large inner diameter at the second end portion (the right side of FIG. 6). At the second end of the second shaft member 42, the stepped hole accommodates the first end portion of the first shaft member 40.

The first operation unit 45 is disposed in the vicinity of the first end portion of the second shaft member 42 (the left side in FIG. 6). A stepped hole is formed in the center of the first operation unit 45. The stepped hole of the first operation unit 45 and the stepped hole of the second shaft member 42 are integrated in the screw holes of the first shaft member 40. The bolt 44 is screwed into the screw hole of the first shaft member 40 through the stepped hole of the first operation unit 45 and the stepped hole of the second shaft member 42. Thereby, the first operation unit 45, the second shaft member 42, and the first shaft member 40 are integrally coupled. The first operation unit 45 is fixed to a dome-shaped pressing portion 45a that covers the head of the bolt 44.

On the other hand, the second end portion (the right side in FIG. 6) having the large outer diameter of the first shaft member 40 is held by the second through hole 15e of the head main body 15. A seal ring 46 is disposed between the first shaft member 40 and the second through hole 15e. The second end of the first shaft member 40 is integrally connected through the press-in sleeve 47 The second operational component 48 is attached.

Next, the operation of the shower head configured as described above will be described with reference to FIGS. 2, 6, and 8.

The shower head 10 of the present embodiment is connected to a water pipe through a shower hose. You can also use hot water instead of water. Further, in the case where the shower head 10 of the present embodiment is only sprayed with water, as shown in Figs. 2 and 6, the first shaft member 40 is moved in the direction of approaching the first through hole 15d (the solution inflow path is self-contained). It is used under the first state of the supply channel block. Further, when the humectant (solution) in which the shower head 10 is sprayed with the sputum 50 is dissolved, as shown in FIG. 8, the first shaft member 40 is moved away from the first through hole 15d (the shower head 10 is licked) The state in which the center axis is the opposite side of the first through hole 15d is moved (the second state in which the solution inflow path communicates with the supply path).

First, it is assumed that the shower head 10 of the present embodiment is used to spray only water. In this case, as shown in FIG. 2, the second operation unit 48 is press-fitted toward the center of the shower head 10, and the first operation unit 45 is used in a state in which it protrudes from the head main body 15. At this time, as shown in FIG. 6, the cylindrical body 35a of the holding unit 35 is engaged with the groove portion 40a of the first shaft member 40. In this state, the (sealing ring 41) of the first shaft member 40 blocks the space between the through hole 32a and prevents water from flowing out from the crucible 50 toward the inner hole 15c (space 72) of the head body 15.

In this state, the water is supplied to the supply hole 12b of the handle portion 12 of Fig. 2 via the shower hose. Water flows into the flow path 70 between the handle portion 12 and the crucible 50 from the supply hole 12b via the periphery of the height portion 12e and around the positioning rib 12f.

The water flowing through the flow path 70 passes through the space 71 between the outlet assembly 55 of the crucible 50 and the head body 15, and the space 72 containing the front end of the holding assembly 35, and flows to the head body 15 Inner hole 15c. This water passes through the microbubble generating unit of the head body 15 to become water mixed with the microbubbles, and is sprayed from the sprinkling hole 16a of the sprinkling unit 16.

In this case, since the space between the first shaft member 40 and the through hole 32a is blocked, the duckbill valve 52 is opened, and water does not flow into the inside of the inner tube 53 of the crucible 50.

Next, the case of the moisturizing liquid (solution) after the spraying agent is dissolved will be described. In this case, the second operation unit 48 is caused to protrude from the head main body 15, and the switching unit 20 is switched to the second state. Specifically, the pressing portion 45a of the first operation unit 45 is pressed toward the center of the shower head 10. Thereby, the first shaft member 40 is pressed, and the front end of the cylindrical body 35a of the holding unit 35 is removed from the groove portion 40a.

Further, after the pressing portion 45a of the first operation unit 45 is moved toward the center of the shower head 10, the seal ring 41 is removed from the through hole 32a of the flow path forming unit 30, and the first shaft member 40 and the through hole 32a are removed. Form a space between them. Further, when the holding unit 35 is moved until it faces the groove portion 40b, it is pressed toward the first shaft member 40 (upper side in the figure) by the spring 36, and is fitted to the groove portion 40b. As a result, as shown in FIG. 8, the second operation unit 48 protrudes from the head main body 15, and the first operation unit 45 is pressed into the head main body 15 to be in the second state.

In this case, water will sequentially pass from the supply hole 12b of the handle portion 12 shown in Fig. 2 through the periphery of the height portion 12e, around the positioning rib 12f, and then into the flow path 70 between the handle portion 12 and the crucible 50. . The water flowing into the flow path 70 flows to the space 71 between the outlet assembly 55 of the crucible 50 and the head body 15, and the space 72 containing the front end of the holding assembly 35.

Further, as shown in FIG. 8, a space is formed between the first shaft member 40 and the through hole 32a, and the inner hole 15c of the head main body 15 is communicated with the stepped hole of the outlet unit 55 through the space. That is, since the inner hole 15c of the head body 15 is in communication with the inner side of the inner tube 53, therefore, FIG. 2 After the duckbill valve 52 is opened, water flows into the inner tube 53 of the crucible 50. The water that has flowed in is supplied to the medicine containing portion 54 via the communication hole 53c of the inner tube 53. Here, the water dissolves the drug in the drug storage portion 54 to become a moisturizing liquid. The moisturizing liquid flows into the stepped holes of the outlet assembly 55 via the filter assembly 57. Then, the moisturizing liquid sequentially flows through the stepped holes of the outlet member 55, the accommodating portion 31a of the flow path forming assembly 30, the communication hole 32b, and the space of the first shaft member 40 and the through hole 32a, and flows to the space 72. In the space 72, water is mixed with the moisturizing liquid to become a diluted moisturizing liquid. Then, the diluted moisturizing liquid flows into the space of the bowl-shaped side portion 15a shown in FIG. 1(b) through the inner hole 15c of the head main body 15, and passes through the microbubble generating unit, thereby becoming microbubble-containing. The diluted moisturizing liquid is sprayed from the sprinkling hole 16a of the sprinkling unit 16.

Then, when the spraying of the moisturizing liquid is to be stopped, the second operation unit 48 is pressed toward the center of the shower head 10 to switch the switching unit 20 to the first state. In this case, the front end of the cylindrical body 35a of the holding unit 35 is removed from the groove portion 40b of the first shaft member 40, and the first shaft member 40 is moved in the direction of the first operation unit 45, and the first shaft member 40 is moved. The space between the through holes 32a is blocked. Then, the holding unit 35 is engaged with the groove portion 40a by the spring 36, and again becomes the first state shown in Fig. 6 .

Therefore, in the above embodiment, the following effects can be obtained.

When the first shaft member 40 is moved in the direction of approaching the first through hole 15d, the space between the first shaft member 40 and the through hole 32a is blocked, and water flows in through the flow path 70 and the spaces 71 and 72. Head 11. When the first shaft member 40 is moved away from the first through hole 15d, the space between the first shaft member 40 and the through hole 32a is opened, and the moisturizing liquid after the medicine is dissolved is supplied from the crucible 50. To the head 11. Thereby, the inside of the crucible 50 can be used as a large space in which the solution after the medicine is dissolved can be accommodated. Further, the cymbal 50 is mounted in the head portion, and the switching portion 20 is provided on the head portion 11 disposed above the shank portion 11, and the tip end portion of the cymbal 50 is fitted to the switching portion 20, so that it is a structure that is less likely to leak. The switching unit 20 switches the spraying of only the water and the spraying of the moisturizing liquid after the medicine is dissolved.

(2) The shower head 10 of the present embodiment is provided with a flow path forming member 30 having an engaging projection 33 to which the holding member 35 is engaged. The holding unit 35 is selectively integrated into the groove portion 40a and the groove portion 40b of the first shaft member 40, and is biased toward the first shaft member 40 by the spring 36. Thereby, the first state in which the space is opened between the first shaft member 40 and the through hole 32a and the second state in which the space is blocked can be more reliably maintained.

(3) The replaceable crucible 50 contained in the shower head 10 of this embodiment accommodates a moisturizing agent as a medicine. Thus, instead of spraying only water, the moisturizing liquid can be easily sprayed.

(4) In the present embodiment, the duckbill valve 52 is disposed on the upstream side of the drug storage portion 54. When the switching unit 20 of the shower head 10 is switched to the second state, a space is formed between the first shaft member 40 and the through hole 32a, and the duckbill valve 52 is opened, and the water flows into the pocket of the crucible 50. The inside of the tube 53. Then, when the outflow side of the crucible 50 is blocked, that is, in the first state, the duckbill valve 52 is blocked, and no more water flows into the medicine containing portion 54. Thus, it is possible to prevent the moisturizing liquid after the dissolution of the drug from flowing back to the shower hose.

(5) The cover 匣 60 of this embodiment is provided with a cover assembly 61 covering the outlet assembly 55 of the cymbal 50. The lid assembly 61 is provided with a cylindrical insertion support portion 61a. The insertion support portion 61a is fitted to the stepped hole at the front end of the outlet assembly 55. Thus, when the replaced crucible 50 is held, the stepped hole deformation of the outlet assembly 55 can be avoided. Therefore, when the cymbal 50 is attached to the shower head 10, it is not easy to cause a gap or the like between the outlet member 55 and the accommodating portion 31a of the flow path forming member 30 accommodating the dam 50, so that the moisturizing liquid is less likely to leak. .
