[0090] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. Furthermore, in this application, the terms "upper side" and "lower side" are used based on the shower head's state when hooked onto the shower hook (reference state). This reference state refers to the standard posture of the shower head in both the active and inactive states.

[0091] Figure 1 This is a perspective view of the shower head 10 according to the first embodiment. Figure 2 This is a cross-sectional view of the shower head 10. Figure 3 This is a three-dimensional view of the main body 100. Figure 4 This is a sectional view of the main body 100. Additionally, in Figure 4 In the middle, the removed medicine containment box 200 is indicated by a double-dotted line.

[0092] The shower head 10 has a main body 100 and a medicine storage box 200.

[0093] The main body 100 has a main section 103 including a water guide section 102 and a water outlet section 104. The main section 103 extends generally vertically. The water guide section 102 has a hose connection section 106, a handle section 108, a main flow path 110, and a main body connection section 112. In addition, the water guide section 102 has a water outlet stop switching section 114. The hose connection section 106 is provided at the lower end of the main body 100. The hose is connected to the hose connection section 106. The handle section 108 is formed on the outer surface of the water guide section 102. The main flow path 110 is formed inside the water guide section 102. The main flow path 110 extends from the hose connection section 106 to the water flow branch section 320 (described later). The main body connection section 112 is provided at the upper end of the main body 103. The medicine storage tank 200 is connected to the main body connection section 112. The medicine storage tank 200 is connected to the main body connection section 112 from the upper side of the main body connection section 112. The outlet-to-stop switching unit 114 constitutes a valve that opens and closes the main flow path 110 by operation. The outlet-to-stop switching unit 114 switches between outlet and stop.

[0094] The water outlet 104 includes: a water sieve 122 having a plurality of water spray holes 120, and a rear section 124 located behind the water sieve 122. The rear section 124 has a water spray path 126 located on the back side of the water sieve 122 and connected to each water spray hole 120.

[0095] The water outlet 104 branches off from the main body 103. The main body connecting portion 112 forms the upper end of the main body 103. The main body connecting portion 112 is located away from the water outlet 104. The main body connecting portion 112 is located behind the water outlet 104. This "behind" refers to the side opposite to the water flow direction. In conventional shower heads, the upper end of the main body is used as the water outlet, but in this embodiment, the water outlet 104 branches off from the main body 103.

[0096] The main body 100 has a branch flow path 130, which branches off from the main flow path 110 and connects to the spray flow path 126 of the water outlet 104. A portion of the water flows directly from the main flow path 110 to the branch flow path 130 without passing through the chemical containment tank 200. This flow is the second water flow R2 (described later).

[0097] like Figure 2 As shown, the medicine storage box 200 has a main body 202 and a lid 204. The medicine storage box 200 is detachably mounted on the main body 100 (see reference).

The periphery is as shown in top view ( Figure 5 (b) is located on the side of the outline k1 near the bottom surface 232a. In other words, the inlet hole 240 is positioned relative to the outlet hole 250 on the central side of the bottom surface 232a. The inlet hole 240 is positioned only on the central side of the bottom surface 232a relative to the outlet hole 250. The central side is the side viewed from above ( Figure 5 (b) refers to the side closest to the center point of the bottom surface 232a. The center point of the bottom surface 232a is the center of the figure formed by the outline k1 when viewed from above. In this embodiment, the outline k1 is a circle when viewed from above, and the center point of the bottom surface 232a is the center of that circle. The opening of the bottom surface 232a of the inlet hole 240 includes the center point of the bottom surface 232a. That is, when viewed from above, the center point of the bottom surface 232a is located inside the inlet hole 240. When viewed from above, the center point of the bottom surface 232a is the center point of the inlet hole 240. Water will not flow from the outlet hole 250 into the agent containing space 230.

The main body engaging portion 146 engages with the engaging portion 216 of the box connecting portion 214. By pressing the medicine container 200 toward the main body connecting portion 112, the engaging portion 216 is slidably inserted into the longitudinal groove 146a. Next, by rotating the medicine container 200, the engaging portion 216 enters the transverse groove 146b and reaches its end. Through this pressing and rotating, the medicine container 200 is installed relative to the main body 100. The disassembly of the medicine container 200 is performed by rotating it and pulling it out.

[0116] The sealing contact surface 148 of the main body connecting portion 112 abuts against the box sealing member 206. Through this contact, the medicine containing box 200 is watertightly connected to the main body portion 100. That is, the box connecting portion 214 is watertightly connected to the main body connecting portion 112. The box sealing member 206 is an example of an annular sealing member disposed between the box connecting portion 214 and the main body connecting portion 112. This annular sealing member can be disposed on the box connecting portion 214 side or on the main body connecting portion 112 side.

[0117] The main body 100 has a main body protruding tube 150. The main body protruding tube 150 forms a flow path extending from the water guide 102. The main body protruding tube 150 has an inner flow path 152. The inner flow path 152 forms a first water flow R1 (described later). The main body protruding tube 150 protrudes upward. The upper end of the main body protruding tube 150 is located below the upper end face 140 of the main body connecting part 112. The main body protruding tube 150 has an upper opening 154. The upper opening 154 is the upper end of the inner flow path 152. The main body protruding tube 150 has a sealing member 156. The sealing member 156 is an annular sealing member. The sealing member 156 is an O-ring. The sealing member 156 watertightly connects the main body protruding tube 150 to the inflow flow path forming part 268. Through this connection, a continuous flow path is formed from the main flow path 110 of the water guide 102 to the inflow hole 240. Water flowing out of outlet 250 will not flow into the continuous flow path.

[0118] The main body protruding tube 150 enters the box protruding tube 264 (refer to) Figure 7 The upper end of the main body protruding tube 150 is located on the upper side compared to the lower end of the box protruding tube 264. The main body protruding tube 150 overlaps with the box protruding tube 264, thereby forming a double-layer tube DP1.

[0119] Figure 9 This is a 3D view of the water flow branch component 300. Figure 9 (b) and Figure 9 (c) is a top view of the water flow branch component 300. Figure 9 (d) is a side view of the water flow branch component 300. Figure 9 (b) and Figure 9 In (c), the phases of the water flow branch component 300 are different.

[0120] The water flow branching component 300 has an upper flow path forming section 302, a lower flow path forming section 304, a branch opening 306, a partition wall 308, and an upper opening 310. The upper flow path forming section 302 and the lower flow path forming section 304 form flow paths on their inner sides. The flow path formed by the water flow branching component 300 is interrupted between the upper flow path forming section 302 and the lower flow path forming section 304. This interrupted portion is the branch opening 306. The branch opening 306 is divided by the partition wall 308. Multiple (three) partition walls 308 are provided. Through these partition walls 308, the branch opening 306 is divided into multiple (three) openings 306a (see reference). Figure 9 (b) and Figure 9 (c)).

[0121] Water flowing through the lower flow path forming section 304 located downstream reaches the branch opening 306. A portion of the water flows into the flow path of the upper flow path forming section 302. The remaining water flows out from the branch opening 306 to the outside of the water flow branching member 300. In this way, the water flow branching member 300 functions as a branch for the water flow.

[0122] In the main body 100, the water flow branch component 300 forms the main body protruding pipe 150. The upper flow path forming part 302 forms the main body protruding pipe 150. The upper opening 310 is the aforementioned upper opening 154.

[0123] Water flowing out of branch opening 306 flows toward branch flow path 130 (see reference) Figure 7 Water flowing out of branch opening 306 flows to water outlet 104 without passing through medicine storage tank 200. Water flowing to upper flow path forming section 302 flows out from upper opening 310 (upper opening 154) and toward medicine storage tank 200.

[0124] By rotating the water flow branch component 300, the amount of water flowing from the branch opening 306 into the branch flow path 130 can be adjusted. Figure 9 In phase (b), both openings 306a face the branch flow path 130. Therefore, the branch flow rate increases. Figure 9 In phase (c), an opening 306a faces the branch flow path 130 side. Therefore, with Figure 9 Compared to phase (b), the branch water volume decreases. When the branch water volume increases, the amount of water reaching the drug containment space 230 decreases, and the duration of the drug increases. When the branch water volume decreases, the amount of water reaching the drug containment space 230 increases, and the duration of the drug decreases. The duration of the drug can be adjusted using the water flow branch component 300.

[0125] The water flow branching component 300 forms a water flow branch 320, which branches a portion of the water flow from the main flow path 110 to the branch flow path 130. In this embodiment, the water flow branch 320 is formed by the water flow branching component 300 as a separate component, but it is not limited to this method. The water flow branch 320 may also be formed by a component integrated with other parts.

[0126] Figure 10 This is a conceptual diagram illustrating the flow of water in the shower head 10. Water flows downstream in the main flow path 110, reaching the water flow branch 320 (water flow branch component 300). In the water flow branch component 300, a portion of the water becomes a branch flow exiting from the branch opening 306 and reaches the outlet 104 via the branch flow path 130. This flow is also referred to as the second water flow R2. The unbranched water flow passes through the main body protruding pipe 150 and the inflow flow path 272, flowing from the inflow hole 240 into the medicine containing space 230. The water flowing into the medicine containing space 230 dissolves the medicine and flows out from the outlet hole 250, reaching the outlet 104 via the branch flow path 130. This flow is also referred to as the first water flow R1.

[0127] like Figure 10As shown, in the absence of any chemicals, the water flowing from the inlet 240 becomes a jet of water. This jet of water reaches the upper surface 232c of the chemical storage space 230. The water pressure in the waterway connected to the shower head 10 is typically around 0.25 to 0.3 MPa. When this water pressure is supplied to the shower head 10 as dynamic water pressure, the water flowing from the inlet 240 becomes a jet of water and reaches the upper surface 232c. Under a dynamic water pressure of 0.2 MPa or higher, the water flowing from the inlet 240 becomes a jet of water and reaches the upper surface 232c. That is, when the dynamic water pressure is 0.2 MPa or higher, the water from the inlet 240 forms a jet of water that reaches the upper surface 232c. Under this dynamic water pressure, regardless of the orientation of the shower head 10, the jet of water from the inlet 240 reaches the upper surface 232c. Under this dynamic water pressure, with the shower head 10 positioned such that the centerline of the inlet hole 240 is vertical, the water jet from the inlet hole 240 reaches the upper surface 232c. Under this dynamic water pressure, in the shower head 10 in the reference state, the water jet from the inlet hole 240 reaches the upper surface 232c. If the cross-sectional area D1 of the inlet hole can be adjusted, it is preferable that the water jet from the inlet hole reaches the upper surface 232c regardless of the cross-sectional area D1. If the ratio (D1 / D2) of the cross-sectional area D1 of the inlet hole to the cross-sectional area D2 of the outlet hole can be adjusted, it is preferable that the water jet from the inlet hole reaches the upper surface 232c regardless of this ratio (D1 / D2). As in the second embodiment described later, if the flow rate ratio of the first water flow R1 to the second water flow R2 can be adjusted, it is preferable that the water jet from the inlet hole reaches the upper surface 232c regardless of this flow rate ratio. In addition, the aforementioned dynamic water pressure is the dynamic water pressure supplied to the shower head 10, and this dynamic water pressure is measured at the water inlet (hose connection 106) in the shower head 10.

[0128] Figure 11 This represents the first water flow R1 immediately after the preparation of reagent 700. In this embodiment, reagent 700 is cylindrical. In this embodiment, reagent 700 is a carbonated tablet. Figure 11 This indicates the state immediately after the preparation of reagent 700, before the dissolution of reagent 700 has occurred. Water flowing in from the inlet hole 240 contacts the bottom surface of reagent 700, dissolving reagent 700 while flowing along the bottom surface 232a of the reagent containing space 230, and flows out from the outlet hole 250.

[0129] Figure 12 The first water flow R1 indicates that the dissolution of agent 700 is in progress. At the point of contact with the water jet from the inlet hole 240, the dissolution of agent 700 proceeds slowly. The water jet slowly erodes agent 700. The water jet creates a hole in agent 700. Finally, the water jet penetrates agent 700. A through hole 702 is formed by the water jet. Figure 12This represents the initial water flow R1 when the through hole 702 is formed. When the through hole 702 is formed, the water jet from the inlet hole 240 contacts the upper surface 232c. Most of the water that contacts the upper surface 232c flows along the side surface 232b, reaches the bottom surface 232a, and is discharged from the outlet hole 250.

[0130] The shower head 10 serves the following functions.

[0131] The medicine storage box 200 can be attached to and detached from the main body 100. Therefore, the replacement of the medicine 700 is easy. Furthermore, the medicine storage box 200 can be installed simply by pressing it against the main body 100 and rotating it, and can be removed simply by rotating it in the opposite direction and pulling it out. The medicine storage box 200 is easy to install and remove.

[0132] Because the medicine container 200 is detachable, it can be replaced. By replacing it with a different model of medicine container 200, the performance of the shower head 10 can be changed. For example, the shower head 10 can have a first medicine container and a second medicine container with different cross-sectional areas of the inlet hole 240. By replacing the medicine container 200, the duration can be easily changed.

[0133] A continuous flow path is formed from the main flow path 110 of the water guide section 102 to the inlet hole 240. Therefore, water pressure reaches the inlet hole 240 and flows into the agent containing space 230. Furthermore, this continuous flow path facilitates the ejection of water from the inlet hole 240. In the above embodiment, the inlet flow path forming section 268 is watertightly connected to the main body protruding pipe section 150, thereby forming this continuous flow path. Even without this watertight connection, a continuous flow path is formed by providing a double-layer pipe section DP2 through the overlap of the main body protruding pipe section 150 and the inlet flow path forming section 268. Furthermore, even without overlap, a continuous flow path is formed by the watertight connection of the inlet flow path forming section 268 and the main body protruding pipe section 150. Water flowing out of the outlet hole 250 does not enter this continuous flow path.

[0134] The inlet hole 240 is disposed only on the central side of the bottom surface 232a relative to the outlet hole 250. Therefore, water flowing out of the inlet hole 240 easily comes into contact with the central side of the agent 700, and easily forms a through hole 702 in the agent 700 (see reference). Figure 12Furthermore, after the through hole 702 is formed, a first water flow R1 easily forms, flowing from the upper surface 232c along the side surface 232b and exiting from the outlet hole 250. This flow is easily formed when the opening of the inlet hole 240 includes the center point of the bottom surface 232a. Providing only one inlet hole 240 facilitates the ejection of water from the inlet hole 240 and the formation of the first water flow R1. Reducing the cross-sectional area D1 of the inlet hole 240 also facilitates the ejection of water from the inlet hole 240 and the formation of the first water flow R1.

[0135] Through the first water flow R1, the parts of the agent 700 that come into contact with water change sequentially from the bottom of the agent 700 to the center of the agent 700, and then to the side surface of the agent 700. Therefore, the agent 700 does not dissolve all at once, allowing for a desired duration of dissolution. In addition, as the water flows along the inner surface 232 of the container, the inner surface 232 of the container is cleaned. Therefore, residues and debris from the agent 700 are removed. Furthermore, since the walls forming the agent container space 230 are transparent, the increased visibility due to the cleaning process makes it easier to assess the condition of the agent 700.

[0136] A protrusion 234 is formed on the bottom surface 232a, and the agent 700 is disposed on the protrusion 234 (high surface h1). Water can flow on the low surface h2, and drainage from the outlet hole 250 becomes smooth. It is possible to suppress the formation of water accumulation in the agent containing space 230 and obtain the desired duration.

[0137] Water from the inlet 240 forms a jet that reaches the upper surface 232c. Thus, the aforementioned water flow is formed. The jet reaching the upper surface 232c is formed when the dynamic water pressure is 0.2 MPa or higher, therefore, the aforementioned water flow can be obtained under normal operating conditions when connected to the water supply system.

[0138] In the shower head 10, a first water flow R1 and a second water flow R2 are formed (see reference). Figure 10 The first water flow R1 travels from the main flow path 110 through the inlet hole 240, the reagent containing space 230, and the outlet hole 250 to the outlet section 104, while the second water flow R2 travels from the main flow path 110 to the outlet section 104 without passing through the reagent containing space 230. By branching the water flow in this way, the water output can be ensured and the desired duration can be achieved.

[0139] The box connector 214 has a downwardly protruding box protrusion tube 264, and the main body 100 has an upwardly protruding main body protrusion tube 150, which forms a flow path toward the inlet hole 240. The box connector 214 and the main body protrusion tube 150 overlap to form a double-layer tube DP1 (see reference). Figure 7Therefore, a continuous flow path can be formed from the main flow path 110 of the water guide section 102 to the inlet hole 240. Water flowing out of the outlet hole 250 will not enter this continuous flow path. Therefore, the aforementioned first water flow R1 is effectively realized. In addition, a structure that allows for easy loading and unloading of the agent storage tank 200 is achieved.

[0140] The box connection portion 214 has an inflow path forming portion 268. The inflow path forming portion 268 is open at the bottom. The lower end of the inflow path forming portion 268 is open. The inflow path forming portion 268 forms an inflow path 272 from the bottom to the inflow hole. The main body protruding tube portion 150 is inserted into the inflow path forming portion 268. Therefore, a double-layer tube portion DP2 is formed with the main body protruding tube portion 150 overlapping the inflow path forming portion 268 (see reference). Figure 7 Therefore, the flow path from the main flow path 110 of the water guide section 102 to the inlet hole 240 is continuous, and the desired duration can be obtained.

[0141] In this embodiment, the main body protruding tube portion 150 is inserted into the inner flow path forming portion 268, but it is also possible that the inner flow path forming portion 268 is inserted into the main body protruding tube portion 150. In this case, a double-layer tube portion DP2 is also formed in which the main body protruding tube portion 150 overlaps with the inflow flow path forming portion 268.

[0142] Furthermore, the inflow path forming section 268 is watertightly connected to the main body protruding pipe section 150. Therefore, the continuity of the flow path from the main flow path 110 of the water guide section 102 to the inflow hole 240 is further improved, and the desired duration can be obtained.

[0143] By pressing the medicine container 200 against the main body 100 and rotating it, the container connecting portion 214 of the medicine container 200 is watertightly connected to the main body connecting portion 112. Therefore, the medicine container 200 is easy to install. The container connecting portion 214 is inserted into the main body connecting portion 112, and an annular sealing member 206 is disposed between the container connecting portion 214 and the main body connecting portion 112. Therefore, the medicine container 200 is easy to install and remove, and a watertight connection is achieved. Furthermore, the connection structure between the main body 100 and the medicine container 200 can be an embedded structure achieved solely by pressing, as described in the above embodiment, or a threaded connection, etc.

[0144] The medicine container 200 is detachably mounted to the main body 100 of the shower head 10. The medicine container 200 has a downwardly protruding container tube 264. Therefore, a structure that allows for easy installation and removal relative to the main body 100 is achieved. Furthermore, a structure that facilitates the formation of a double-layer tube DP1 between the medicine container 200 and the main body 100 is realized. The inlet hole 240 and the outlet hole 250 communicate with the inside of the container tube 264, thus achieving a structure that allows for easy installation and removal relative to the main body 100.

[0145] A water flow dividing section 274 is provided inside the protruding pipe section 264 of the box (see reference). Figure 6 (b) The water flow dividing section 274 separates the inflow path for water entering the inflow hole 240 from the flow path for water flowing out of the outflow hole 250. Therefore, the distinction between the inflow hole 240 and the outflow hole 250 becomes clear. The inflow path for water entering the inflow hole 240 is formed inside the water flow dividing section 274, and the flow path for water flowing out of the outflow hole 250 is formed between the water flow dividing section 274 and the wall of the forming box protrusion tube 264. Therefore, the inflow hole 240 can be positioned relative to the outflow hole 250 at the center of the bottom surface 232a.

[0146] The medicine storage box 200 consists of a main body 202 and a lid 204. The main body 202 has a box opening 210 that opens the medicine storage space 230 upwards and a box connecting part 214. The lid 204 closes the box opening 210. With this structure, the medicine 700 can be easily placed in the medicine storage space 230.

[0147] From the viewpoint of obtaining the jet volume of water flowing out of the inlet hole 240, the cross-sectional area D1 of the inlet hole 240 is preferably 0.5 mm² or more, more preferably 0.6 mm² or more, and even more preferably 0.7 mm² or more. From the viewpoint of obtaining the jet height of water flowing out of the inlet hole 240, the cross-sectional area D1 is preferably 15 mm² or less, more preferably 14 mm² or less, and even more preferably 13 mm² or less. Furthermore, in the above embodiment, the inlet hole 240 is a circular hole, and the cross-sectional area D1 is the area of ​​a circle calculated based on the hole diameter. When there are multiple inlet holes, the sum of the cross-sectional areas of these inlet holes is the cross-sectional area D1. The cross-sectional area D1 can also be the opening area at the bottom surface 232a.

[0148] In the case where the agent 700 is a gas-generating agent such as a carbonated tablet, if the cross-sectional area D2 of the outlet hole 250 is small, the internal pressure of the agent containing space 230 will increase, and the inflow of water from the inlet hole 240 will be obstructed. From this viewpoint, the cross-sectional area D2 of the outlet hole 250 is preferably 20 mm2 or more, more preferably 25 mm2 or more, and more preferably 30 mm2 or more. From the viewpoint of suppressing the limitation of the agent containing box on the wall thickness design, the cross-sectional area D2 is preferably 45 mm2 or less, more preferably 40 mm2 or less, and more preferably 35 mm2 or less. In addition, as in the above embodiment, when there are multiple outlet holes 250, the total cross-sectional area of ​​these outlet holes 250 is the cross-sectional area D2. In the above embodiment, the cross-sectional area D2 is a top view of the bottom surface 232a ( Figure 5 The area of ​​the outflow hole 250 in (b)).

[0149] By optimizing the ratio (D1 / D2), the inflow rate from the inlet orifice 240 and the outflow rate from the outlet orifice 250 are appropriately adjusted to obtain the desired duration. The ratio (D1 / D2) is preferably 0.005 or more, more preferably 0.01 or more, and even more preferably 0.02 or more. The ratio (D1 / D2) is preferably 0.50 or less, more preferably 0.45 or less, and even more preferably 0.40 or less.

[0150] Figure 7 The double arrow D3 indicates the inner diameter of the medicine container 200. Commercially available carbonated tablets sometimes expand, therefore the inner diameter D3 is preferably larger than the outer diameter of the carbonated tablet. Considering a medicine (carbonated tablet) with an outer diameter of 27 mm, the inner diameter D3 is preferably 29 mm or more, more preferably 30 mm or more, and even more preferably 31 mm or more. If the inner diameter D3 is too large, the medicine 700 will move significantly within the medicine container space 230, thus increasing the deviation in duration. From this perspective, the inner diameter D3 is preferably 45 mm or less, more preferably 40 mm or less, and even more preferably 35 mm or less.

[0151] The dissolution method and duration of the carbonated tablets were verified using shower head 10. Two medicine containers 200 with different inlet orifice diameters 240 were prepared, and the shower heads of Examples 1 and 2 were obtained by replacing them. In Example 1, the orifice diameter of the inlet orifice 240 was set to 1 mm (cross-sectional area D1 is 0.785 mm2), and the cross-sectional area D2 of the outlet orifice 250 was set to 32.052 mm2. In Example 2, the orifice diameter of the inlet orifice 240 was set to 4 mm (cross-sectional area D1 is 12.6 mm2), and the cross-sectional area D2 of the outlet orifice 250 was set to 32.052 mm2.

[0152] The shower head 10 was connected to the water supply (water pressure 0.2 MPa), and the water temperature was set to 40°C for actual water output. First, in Examples 1 and 2, showering was performed with the chemical storage space 230 empty. In either embodiment, water... Figure 10 As shown, the water branches into two streams. The water jet from the inlet 240 reaches the upper surface 232c and then flows along the inner surface 232 of the container. Regardless of the position of the shower head 10, the water jet from the inlet 240 reaches the upper surface 232c. Next, when a 27mm outer diameter medicine (carbonated tablet) 700 was placed in the medicine container of Example 1 and water was dispensed, it was confirmed that the dissolved portion of the medicine (carbonated tablet) 700 changed sequentially from the bottom surface, center, and side surface, thus forming a through hole 702. When the same medicine (carbonated tablet) 700 was placed in the medicine container of Example 2, it was confirmed that the dissolved portion of the medicine (carbonated tablet) 700 changed sequentially from the bottom surface, center, and side surface, thus forming a through hole 702. Due to the transparency of the medicine container 200, the water flow and the dissolved state of the carbonated tablets inside the medicine container 200 can be observed from the outside. The duration in Example 1 was 5 minutes, and the duration in Example 2 was 2 minutes. This confirms that the duration can be changed simply by replacing the medicine containment box 200.

[0153] The drug 700 is disposed in the drug receiving space 230. The drug 700 has the size and shape to be received in the drug receiving space 230. A typical drug 700 is a tablet.

[0154] The reagent 700 is not limited. Preferably, the reagent 700 is a solid. The reagent 700 dissolves in water and reacts with the effluent. Examples of components included in the reagent 700 include sodium sulfate, sodium chloride, sodium borate carbonate, potassium carbonate, hyaluronic acid, L-ascorbic acid, citric acid, sodium bicarbonate, etc. The reagent 700 may also contain crude drugs, seaweed extracts, etc. In this embodiment, the reagent 700 is a carbonated tablet. The carbonated tablet reacts with water to produce carbon dioxide gas.

[0155] Figure 13 (a) is a top view of the box body 402, which is a modified example of the box body 202. Figure 13 (b) is along Figure 13 (a) is a cross-sectional view of the BB line. Figure 13 (c) is along Figure 13 (a) is a cross-sectional view of the CC line. Figure 14 (a) is also a top view of the main body 402 of the box. Figure 14 (b) is along Figure 14 (a) is a cross-sectional view of the BB line. Figure 14 (c) is along Figure 14 (a) A cross-sectional view along the CC line. Figure 13 (a) to (c) and Figure 14 Between (a) and (c), the position of the moving part 404 is different. Figure 13 In (a) to (c), the moving part 404 is located in the first position. Figure 14 In (a) to (c), the moving part 404 is located in the second position.

[0156] The main body 402 of the container includes a moving member 404, a sliding groove 406, an inlet hole 408, and an outlet hole 410. The moving member 404 has a sliding engagement portion 404a and a through hole 404b. The sliding engagement portion 404a is a stepped portion formed on the outer peripheral surface of the moving member 404. The sliding groove 406 is interrupted at the portion where the outlet hole 410 is formed (see reference). Figure 14 (b)), but the distance of the interruption is short enough not to impede the movement of the moving part 404 from the first position to the second position. A sliding mechanism for moving the moving part 404 is formed by the sliding engagement part 404a and the sliding groove 406. During the movement of the moving part 404, the sliding engagement part 404a slides in the sliding groove 406.

[0157] like Figure 13 As shown in (a) to (c), the movable part 404 in the first position completely covers the inlet hole 408. However, since the through hole 404b communicates with the inlet hole 408, water flows into the reagent containing space from the through hole 404b. In this case, the cross-sectional area of ​​the inlet hole is the same as the cross-sectional area of ​​the through hole 404b. This cross-sectional area is smaller than the cross-sectional area of ​​the inlet hole 408.

[0158] like Figure 14 As shown in (a) to (c), the moving part 404 in the second position is completely deviated from the inlet hole 408. In this case, the inlet hole 408 functions fully. In this case, the cross-sectional area of ​​the inlet hole is the same as the cross-sectional area of ​​the inlet hole 408.

[0159] When the movable component 404 is located between the first position and the second position, the movable component 404 can partially cover the inlet hole 408. In this case, the cross-sectional area of ​​the inlet hole can gradually change according to the position of the movable component 404.

[0160] Thus, the medicine containing box of the main body 402 has an adjustment mechanism capable of adjusting the cross-sectional area of ​​the inlet hole. The medicine containing box of the main body 402 has an adjustment mechanism capable of adjusting the ratio (D1 / D2) of the cross-sectional area D1 of the inlet hole to the cross-sectional area D2 of the outlet hole. This adjustment mechanism is implemented by a movable member 404 that can move to a position covering the inlet hole 408 and a position not covering the inlet hole 408.

[0161] Additionally, the main body 402 of the box has a protrusion 412 that engages with the movable member 404 located in the second position. For example... Figure 14 As shown in (b) and (c), the protrusion 412 engages with the through hole 404b. The protrusion 412 helps to hold the moving part 404 in the second position.

[0162] The movable part 404 can be easily moved, for example, by a finger. The movement of the movable part 404 is easy even without the cap and the medicine.

[0163] Figure 15 This is a perspective view of the shower head 20 according to the second embodiment, viewed from the rear side. Except for having a rotating mechanism that allows external rotation of the water flow branching component, the shower head 20 is identical to the shower head 10. The shower head 20 includes a medicine storage tank 200 and a main body 500.

[0164] Figure 16 (a) is a top view of the main body 500 as seen from above. The main body 500 has a water flow branch component 600.

[0165] Figure 17 (a) is a perspective view of the water flow branch component 600. Figure 17 (b) is a top view of the water flow branch component 600.

[0166] The flow branch component 600 has the same structure as the aforementioned flow branch component 300. The flow branch component 600 has an upper flow path forming portion 602, a lower flow path forming portion 604, a branch opening 606, a partition wall 608, and an upper opening 610. The upper flow path forming portion 602 and the lower flow path forming portion 604 form flow paths on their inner sides. These flow paths constitute part of the main flow path.

[0167] The flow path formed by the water flow branch component 600 is interrupted between the upper flow path forming section 602 and the lower flow path forming section 604. This interrupted section is the branch opening 606. The branch opening 606 is divided by partition walls 608. Multiple (three) partition walls 608 are provided. Through these partition walls 608, the branch opening 606 is divided into multiple (three) openings 606a (see reference). Figure 17 (b) Similar to the aforementioned water flow branch component 300, by rotating the water flow branch component 600, the amount of branch water flowing from the branch opening 606 into the branch flow path 130 can be adjusted.

[0168] Unlike the water flow branching component 300, the water flow branching component 600 has an operating part 612. The operating part 612 extends from the main body of the water flow branching component 600 to the outer surface of the main body 500. The operating part 612 has an outward extension 614, a rotating sliding part 616, and an exposed part 618.

[0169] Figure 16 (b) is in Figure 16 The diagram shows the hidden portion of the operating unit 612 added to the top view of (a). From an easy-to-observe perspective, in Figure 16 In (b), the part that should be represented by a dashed line is indicated by black.

[0170] An outer extension 614 extends between the main body of the water flow branch component 600 and the rotating sliding portion 616. The rotating sliding portion 616 has a shape along the inner surface (inner circumferential surface) of the outer wall 504, which forms the holding portion 502 of the main body 500. The rotating sliding portion 616 abuts against the inner surface of the outer wall 504. When the water flow branch component 600 rotates, the rotating sliding portion 616 slides on the inner surface of the outer wall 504. An exposed portion 618 protrudes to the outside. The exposed portion 618 is a protrusion provided on the outer surface of the rotating sliding portion 616. The exposed portion 618 protrudes to the outside from an opening window 506 provided on the outer wall 504. The opening window 506 functions as a sliding portion that guides the movement of the exposed portion 618. The user can rotate the water flow branch component 600 by moving the exposed portion 618 by hand. In this way, a mechanism for operating (rotating) the flow path branch component 600 from the outside can also be provided. This mechanism allows for the change of the ratio of the first water flow R1 to the second water flow R2 through external manipulation.

[0171] Figure 18 This is an enlarged cross-sectional view of the shower head 30 according to the third embodiment. Figure 19 This is an enlarged cross-sectional view showing the medicine container in its separated state. Figure 20 This is a perspective view of the main body 800 of the shower head 30. Unless otherwise stated below, the shower head 30 is the same as the shower head 10 of the first embodiment.

[0172] The shower head 30 has a main body 800 and a medicine storage box 900.

[0173] The main body 800 has a main section 803 including a water guide section 802 and a water outlet section 804. The main section 803 extends generally vertically. The water guide section 802 has a gripping section 808, a main flow path 810, and a main body connecting section 812. The gripping section 808 is formed on the outer surface of the water guide section 802. The main flow path 810 is formed inside the water guide section 802. The main body connecting section 812 is provided at the upper end of the main section 803. A medicine storage box 900 is connected to the main body connecting section 812. The medicine storage box 900 is connected to the main body connecting section 812 from the upper side of the main body connecting section 812.

[0174] The main body 800 has a branch flow path 830, which branches off from the main flow path 810 and connects to the water outlet 804. A portion of the water bypasses the reagent storage tank 900 and flows directly from the main flow path 810 to the branch flow path 830 and then to the water outlet 804. This flow is the aforementioned second water flow R2.

[0175] like Figure 18 and 19 As shown, the medicine storage box 900 has a main body 902 and a cover 904. The medicine storage box 900 is detachably mounted to the main body 800. The medicine storage box 900 is watertightly mounted to the main body 800. The medicine storage box 900 has a box sealing member 906. The box sealing member 906 seals the medicine storage box 900 and the main body 800. The box sealing member 906 is an annular sealing member. The box sealing member 906 is an O-ring. The box sealing member 906 may also be a sealing member other than an O-ring. The box sealing member 906 may also be provided on the side of the main body connection portion 812.

[0176] Figure 21 (a) is a perspective view of the main body 902 of the box. Figure 21 (b) is a top view of the main body 902 of the box. Figure 21 (c) is a side view of the main body 902 of the box. Figure 21 (d) is a bottom view of the main body 902 of the box.

[0177] The main body 902 has a box opening 910 and a lid engagement portion 912. The box opening 910 is formed at the upper end of the main body 902. The box opening 910 opens the medicine containing space 930 upwards. The medicine 700 is disposed in the medicine containing box 900 through the box opening 910. The lid engagement portion 912 is externally threaded. This lid engagement portion 912 engages with the internal thread of the lid portion 904. The lid portion 904 is threadedly engaged with the main body 902.

[0178] The main body 902 of the case has a case connecting portion 914. The case connecting portion 914 is located at the lower part of the main body 902 (medicine storage case 900). The case connecting portion 914 has engaging portions 916. Multiple (four) engaging portions 916 are provided. The engaging portions 916 are protrusions. Figure 21 As shown in (d), multiple locking parts 916 are evenly distributed circumferentially in the medicine storage box 900.

[0179] like Figure 21 As shown in (c), the main body 902 of the box has a lid sealing configuration portion 918. The lid sealing configuration portion 918 is a groove along the circumference. Although in Figure 21 Illustrations are omitted in (a) to (d), but a cover sealing component 920 is provided in the cover sealing configuration section 918 (see reference). Figure 18 , 19The cover sealing component 920 is an O-ring. The cover sealing component 920 seals the space between the main body 902 and the cover 904.

[0180] like Figure 21 As shown in (c), the main body 902 (medicine storage box 900) has a connecting sealing configuration 922. The connecting sealing configuration 922 is a groove along the circumference. The box connection 914 has a box sealing member 906. Although in Figure 21 Illustrations are omitted in (a) to (d), but the aforementioned box sealing component 906 is provided in the connecting sealing configuration section 922 (see reference). Figure 18 , 19 ).

[0181] The main body 902 of the box has a side wall 924. The side wall 924 is a cylindrical wall. The side wall 924 forms the side surface 932b that accommodates the inner surface 932. The upper side of the side wall 924 is open, thereby forming a box opening 910.

[0182] The main body 902 of the case is transparent. The main body 902 of the case is formed of a transparent resin. Due to this transparency, the medicine 700 contained inside the medicine storage case 900 can be visually identified from the outside.

[0183] The medicine storage box 900 has a box connection part 914 and a medicine storage space 930. The box connection part 914 is located on the lower side of the medicine storage space 930.

[0184] The medicine containing box 900 has an inner surface 932. The inner surface 932 divides the medicine containing space 930. The inner surface 932 faces the medicine containing space 930. The inner surface 932 has a bottom surface 932a, a side surface 932b, and a top surface 932c. The bottom surface 932a has a protrusion 934. The protrusion 934 protrudes upward. Due to the protrusion 934, a portion of the bottom surface 932a becomes higher. The bottom surface 932a has a high surface h1 and a low surface h2. The high surface h1 is the upper surface of the protrusion 934. The low surface h2 is located lower than the high surface h1. The side surface 932b is formed by a side wall portion 924. The side surface 932b is the inner surface 924b of the side wall portion 924. The top surface 932c is formed by a cover portion 904. The top surface 932c is the inner surface 904b of the cover portion 904.

[0185] The medicine containing box 900 has a flow hole 940. There is only one flow hole 940. The flow hole 940 is the only opening formed on the inner surface 932 of the containing box. Multiple flow holes 940 may also be provided. The flow hole 940 opens on the bottom surface 932a. The flow hole 940 opens on the lower surface h2. The flow hole 940 allows water to flow into the medicine containing space 930 and allows water within the medicine containing space 930 to flow out.

[0186] The agent 700 is placed on the protrusion 934. The agent 700 is placed on the high surface h1. The agent 700 is in a state of floating from the low surface h2. The flow hole 940 is open at the low surface h2. Because the agent 700 floats from the low surface h2, water can easily flow on the bottom surface 932a. In particular, the outflow of water from the flow hole 940 becomes smooth. This facilitates the formation of the second water flow R2. In addition, because the agent 700 floats from the low surface h2, excessive dissolution of the agent 700 due to water retention can be suppressed, and the desired duration can be obtained.

[0187] In the combination of the medicine storage box 900 and the medicine 700, the medicine 700 has the shape and size of a medicine storage space 930 housed within the medicine storage box 900. The medicine 700 is preferably disposed in the medicine storage space 930 in a state that abuts against the higher surface h1 and floats from the lower surface h2.

[0188] The opening of the flow hole 940 includes the center point of the bottom surface 932a. That is, when viewed from above, the center point of the bottom surface 932a is located inside the flow hole 940. In this embodiment, when viewed from above, the center point of the bottom surface 932a is the center point of the flow hole 940.

[0189] like Figure 19 As shown, the lower part of the medicine container 900, the box connecting portion 914, has an outer peripheral surface 958, a lower opening 960, a connecting cavity 962 extending upward from the lower opening 960, and a lower end surface 963. The lower opening 960 is formed at the lower end of the medicine container 900. The connecting cavity 962 is open downward. The lower end surface 963 is also the lower end surface of the medicine container 900. The box connecting portion 914 has a box protrusion tube 964. The box protrusion tube 964 protrudes downward. The lower opening 960, the connecting cavity 962, and the lower end surface 963 are formed by the box protrusion tube 964. The connecting cavity 962 is divided by the inner peripheral surface 966 of the box protrusion tube 964. The aforementioned engaging portion 916 is provided on the outer peripheral surface 958 of the box protrusion tube 964.

[0190] The flow hole 940 communicates with the inside of the protruding tube portion 964. The flow hole 940 communicates with the connecting cavity portion 962. Water flows into the medicine containing space 930 through the flow hole 940 via the connecting cavity portion 962. Water flows out of the flow hole 940 through the connecting cavity portion 962 and toward the water outlet portion 804. The connecting cavity portion 962 forms an inflow and outflow path through which water flowing into and out of the flow hole 940 passes. In the medicine containing box 800, the water flowing into the medicine containing space 930 and the water flowing out of the medicine containing space 930 are not separated.

[0191] like Figure 19 and Figure 20As shown, the main body connecting portion 812 has an upper end face 840 and an insertion support portion 842. The box connecting portion 914 of the medicine receiving box 900 is inserted into the main body connecting portion 812. The insertion support portion 842 forms the inner surface of the main body connecting portion 812. The insertion support portion 842 has a circumferential inner surface 844 and a main body engaging portion 846. The circumferential inner surface 844 has a sealing abutment surface 848. The insertion support portion 842 supports the box connecting portion 814 inserted into the main body connecting portion 812. The circumferential inner surface 844 supports the outer circumferential surface 958 of the box connecting portion 914. The main body engaging portion 846 has: a longitudinal groove 846a, which is open on the upper side and extends along the insertion direction (vertical direction); and a transverse groove 846b, which is connected to the lower end of the longitudinal groove 846a and extends circumferentially from the lower end. The main body engaging portion 846 engages with the engaging portion 916 of the box connecting portion 914. By pressing the medicine container 900 toward the main body connecting portion 812, the engaging portion 916 slides into the longitudinal groove 846a. Then, by rotating the medicine container 900, the engaging portion 916 enters the transverse groove 846b and reaches its end. Through this pressing and rotating, the medicine container 900 is installed relative to the main body portion 800. The disassembly of the medicine container 900 is the reverse action: by rotating the medicine container 900, it is pulled out. The installation and disassembly of the medicine container 900 are easy.

[0192] The sealing contact surface 848 of the main body connection part 812 abuts against the box sealing component 906 (see reference). Figure 18 Through this contact, the medicine container 900 is watertightly connected to the main body 800. That is, the container connecting part 914 is watertightly connected to the main body connecting part 812. The container sealing member 906 is an example of an annular sealing member disposed between the container connecting part 914 and the main body connecting part 812. This annular sealing member can be disposed on the side of the container connecting part 914 or on the side of the main body connecting part 812.

[0193] like Figure 18 and Figure 19 As shown, the main body 800 has an on / off valve 850. The on / off valve 850 has a valve seat 852 and a valve core 854. The valve seat 852 has a conical concave surface. The valve core 854 has a valve sealing member 856 and a base 858. The valve sealing member 856 is an annular sealing member. The valve sealing member 856 is an O-ring. The valve sealing member 856 abuts against the valve seat 852.

[0194] Figure 22 (a) is a perspective view of the base 858 of the valve core 854. Figure 22 (b) is a top view of the base 858. Figure 22 (c) is a side view of the base 858. Figure 22 (d) is a bottom view of the base 858.

[0195] The valve core 854 (base 858) includes: a valve core base 861 with a sealing configuration part 860 on its outer periphery, a valve core abutment part 862, and a valve sliding part 864.

[0196] The valve core base 861 forms a watertight, disc-shaped portion. A sealing arrangement portion 860 is provided on the outer periphery of the valve core base 861. The sealing arrangement portion 860 is a groove along the circumferential direction. A valve sealing member 856 (see reference) is disposed in the sealing arrangement portion 860. Figure 18 and Figure 19 Valve sealing component 856 is an annular sealing component. Valve sealing component 856 is an O-ring.

[0197] The valve core abutment portion 862 is composed of a protrusion that protrudes upward from the valve core base portion 861. Multiple (three) of these protrusions are formed. The end face of this protrusion abuts against the lower end face 963 of the medicine storage box 900 (the lower end face 963 of the box connection portion 914).

[0198] The valve sliding portion 864 is a plate-shaped portion protruding downwards. The valve sliding portion 864 slidably engages with the sliding guide portion described later, thereby allowing the valve core 854 to move.

[0199] Figure 23 (a) is a perspective view of valve adjacent component 870. Figure 23 (b) is a top view of the valve adjacent component 870. Figure 23 (c) is a front view of the valve adjacent component 870. Figure 23 (d) is a side view of the valve adjacent component 870.

[0200] The valve abutment member 870 is a nut member that secures the components of the main part 803 constituting the main body part 800 in an assembled state. Additionally, the valve abutment member 870 has an inner flow path 872. The inner flow path 872 communicates with the main flow path 810.

[0201] The valve abutment member 870 has a sliding guide portion 874. The sliding guide portion 874 is formed by an upper-opening slit portion. This slit portion is provided at two circumferential locations of the valve abutment member 870. For example... Figure 18 and Figure 19 As shown, the valve sliding part 864 is inserted into the sliding guide part 874 from the top. The valve sliding part 864 can slide within the sliding guide part 874.

[0202] The valve core 854 can reciprocate along the valve opening and closing direction by sliding engagement between the sliding guide 874 and the valve sliding part 864. The valve opening and closing direction is the up and down direction.

[0203] When the valve core 854 moves in the valve closing direction, the valve sealing component 856 presses tightly against the valve seat 852, and the opening / closing valve 850 closes (see reference). Figure 19 In this embodiment, the valve closing direction is upward. Due to water pressure, the valve core 854 is forced in the valve closing direction. As long as the reagent container 900 does not obstruct movement in the valve closing direction, the valve 850 closes due to water pressure. Alternatively, a force-applying component may be provided to apply force to the valve core 854 in the valve closing direction.

[0204] When the medicine container 900 is installed on the main body 800, the container connection 914 (the container protruding tube 964) overcomes the force generated by water pressure, causing the valve core 854 to move in the valve opening direction. In this embodiment, the valve opening direction is downward. The container connection 914 presses down the valve core 854. The lower end face 963 abuts against the valve core abutment portion 862 of the valve core 854, causing the valve core 854 to move in the valve opening direction. As a result, the valve sealing member 856 moves away from the valve seat 852, and the opening / closing valve 850 opens (see reference). Figure 18 The medicine storage box 900 has a valve opening abutment portion 965. When the medicine storage box 900 is installed on the main body 800, the valve opening abutment portion 965 abuts against the valve core 854 (valve core abutment portion 862), thereby causing the valve core 854 to move in the opening direction. The valve opening abutment portion 965 is the lower end face 963.

[0205] Thus, the on / off valve 850 opens and closes the flow path of the main body 800 extending from the main flow path 810 toward the main body connection portion 812 (flow hole 940). When the medicine storage box 900 is installed on the main body 800, the box protrusion tube 964 presses the valve core 854 of the on / off valve 850 to open the on / off valve 850. When the medicine storage box 900 is removed from the main body 800, the pressure of the box protrusion tube 964 on the valve core 854 is released, and the on / off valve 850 closes.

[0206] The on / off valve 850 allows the use of the medicine 700 at any time. For example, the shower head 30 can be used without the medicine storage tank 900 installed, or the medicine storage tank 900 can be installed during use. Alternatively, the shower head 30 can be used with the medicine storage tank 900 installed, or the medicine storage tank 900 can be removed during use. Even if the medicine storage tank 900 is removed during use of the shower head 30, water will not blow out from the main body connection 812 because the on / off valve 850 is closed. Even if the medicine storage tank 900 is accidentally detached, water will not blow out. Furthermore, by removing the medicine storage tank 900 midway through showering, the lifespan of the medicine 700 can be extended, and the medicine 700 will not be completely used up. This on / off valve 850 can also be applied to the shower head 10 of the first embodiment and the shower head 20 of the second embodiment.

[0207] In the shower head 30, a first water flow and a second water flow are also formed. The first water flow travels from the main flow path 810 through the chemical storage space 930 to the water outlet 804, while the second water flow travels from the main flow path 810 to the water outlet 804 without passing through the chemical storage space 930. By branching the water flow in this way, the water output is ensured and the desired duration is achieved. The valve abutment part 870 and the valve core 854 participate in this branching of the water flow. A portion of the water that has passed through the inner flow path 872 contacts the valve core base 861 of the valve core 854 and flows into the branch flow path 830. Another portion of the water that has passed through the inner flow path 872 flows towards the chemical storage space 930 through the on / off valve 850. When the on / off valve 850 is closed, water does not pass through the on / off valve 850, and the water flow becomes only the aforementioned second water flow. When the on / off valve 850 is in the open state, the opening of the on / off valve 850 makes the first water flow possible, thus forming the first water flow and the second water flow.

[0208] Examples of materials used for the cover 204 of the medicine container 200 include resin and metal. From the viewpoint of ease of molding and superior manufacturability, thermoplastic resin is preferred as the resin. Since the cover 204 is an externally exposed component, a material suitable for vapor deposition is preferred. From this perspective, acrylonitrile-butadiene-styrene copolymer (ABS) is preferred among thermoplastic resins.

[0209] Examples of materials used for the main body 202 of the medicine storage box 200 include resin and metal. From the viewpoint of ease of molding and superior manufacturability, thermoplastic resins are preferred as resins. From the viewpoint of being able to visually confirm the amount of medicine remaining, the main body 202 of the box is preferably transparent. Furthermore, the main body 202 of the box preferably has the strength to withstand the impact of a fall. From these viewpoints, polycarbonate (PC) is preferred among thermoplastic resins.

[0210] Rubber is preferably used as the material for the sealing component 206 of the container. Since the medicine container 200 is installed and disassembled frequently, a material with excellent wear resistance is preferred. From this perspective, nitrile rubber (NBR) is preferred among the rubbers used.

[0211] Examples of materials for the main body protruding tube 150 include resin and metal. From the viewpoint of ease of molding and superior manufacturability, thermoplastic resin is preferred as the resin. From the viewpoint of fixation to the main body 100 and support for the agent storage box 200, POM (polyoxymethylene) is preferred among thermoplastic resins.
