外側筒体１７と内側筒体１６との間に介在する上流側閉塞部１９と下流側閉塞部２０は、円盤ドーナツ形状の部材であって、下方基盤３３と上方基盤３２の薬剤収容室１５側の内面に各々回転スライド可能に密着して取り付けられる。また上流側閉塞部１９と下流側閉塞部２０は、シール性を確保するためのＯ−リングを適宜の位置に介在させつつ、上流側閉塞部１９と下流側閉塞部２０の外周面を外側筒体１７の内周面に各々接合一体化すると共に、これらの内周面を内側筒体１６の外周面に各々回転スライド可能に密着させて取り付けられる。これによって上流側閉塞部１９と下流側閉塞部２０は、内側筒体１６を中心とした周方向Ｙに、外側筒体１７と一体となって回転移動することになる。 An upstream side blocking portion 19 and a downstream side blocking portion 20 interposed between the outer cylinder body 17 and the inner cylinder body 16 are disk-shaped donut-shaped members, and are on the side of the medicine container 15 of the lower base 33 and the upper base 32. Are attached in close contact with each other so as to be slidable. Further, the upstream side blocking portion 19 and the downstream side blocking portion 20 are provided with the outer peripheral surfaces of the upstream side blocking portion 19 and the downstream side blocking portion 20 on the outer cylinder while interposing an O-ring for ensuring sealing performance at an appropriate position. The inner peripheral surfaces of the body 17 are joined and integrated, and these inner peripheral surfaces are attached to the outer peripheral surface of the inner cylindrical body 16 so as to be slidably rotatable. As a result, the upstream blocking portion 19 and the downstream blocking portion 20 rotate together with the outer cylinder 17 in the circumferential direction Y around the inner cylinder 16.

また、上流側閉塞部１９と下流側閉塞部２０の内部には、これらの断面中央部分を同心状かつ円環状に貫通するようにして、原水流入路２１及び流出路２２が、周方向Ｙに沿って延設して各々形成されている。原水流入路２１が形成された上流側閉塞部１９には、内側筒体１６の上流側連通孔３４と合致することが可能な周方向Ｙの特定の位置に、内側筒体１６の外周面を覆う当該上流側閉塞部１９の内壁部分を貫通して、原水流入口３７（図４（ｂ）参照）が形成されている。また原水流入路２１の天面壁部分を貫通して、収容室連通孔３８が周方向Ｙに複数箇所開口形成されており、これらの収容室連通孔３８を介して、原水流入路２１から薬剤収容室１５に原水を供給することができるようになっている。 Further, in the upstream side blocking portion 19 and the downstream side blocking portion 20, the raw water inflow passage 21 and the outflow passage 22 are arranged in the circumferential direction Y so as to penetrate the central portion of the cross section concentrically and in an annular shape. Each of them extends along the line. In the upstream side blocking portion 19 where the raw water inflow passage 21 is formed, the outer peripheral surface of the inner cylindrical body 16 is placed at a specific position in the circumferential direction Y that can match the upstream communication hole 34 of the inner cylindrical body 16. A raw water inlet 37 (see FIG. 4B) is formed through the inner wall portion of the upstream blocking portion 19 to be covered. Further, through the top wall portion of the raw water inflow passage 21, a plurality of storage chamber communication holes 38 are formed in the circumferential direction Y, and the medicine is stored from the raw water inflow passage 21 through these storage chamber communication holes 38. Raw water can be supplied to the chamber 15.

一方、流出路２２が形成された下流側閉塞部２０には、内側筒体１６の下流側連通孔３５と合致することが可能な周方向Ｙの特定の位置に、内側筒体１６の外周面を覆う当該下流側閉塞部２０の内壁部分を貫通して、流出口３９（図４（ｂ）参照）が、原水流入口３７と同じ方向に開口して形成されている。また流出路２２の下面壁部分を貫通して、収容室連通孔４０が周方向Ｙに複数箇所開口形成されており、これらの収容室連通孔４０を介して、混合用薬剤を混入した原水を薬剤収容室１５から流出路２２に排出することができるようになっている。 On the other hand, in the downstream blocking portion 20 where the outflow path 22 is formed, the outer peripheral surface of the inner cylinder 16 is located at a specific position in the circumferential direction Y that can match the downstream communication hole 35 of the inner cylinder 16. An outlet port 39 (see FIG. 4B) is formed so as to open in the same direction as the raw water inlet port 37 through the inner wall portion of the downstream blocking portion 20 covering the same. A plurality of storage chamber communication holes 40 are formed in the circumferential direction Y so as to penetrate the lower wall portion of the outflow passage 22, and the raw water mixed with the mixing agent is passed through these storage chamber communication holes 40. The medicine can be discharged from the medicine storage chamber 15 to the outflow path 22.

そして、本第１実施形態によれば、内側筒体１６に対する上流側閉塞部１９及び下流側閉塞部２０が一体となった外側筒体１７の相対的な回転移動によって、図４（ａ）に示すような、上流側連通孔３４及び下流側連通孔３５と、原水流入口３７及び流出口３９とが互いにずれて原水流入路２１及び流出路２２が閉塞された状態と、図４（ｂ）に示すような、上流側連通孔３４及び下流側連通孔３５と、原水流入口３７及び流出口３９とが互いに合致して原水流入路２１及び流出路２２が開放された状態とを切り替えて、原水流入路２１及び流出路２２の開閉操作を容易に行うことが可能になる。 And according to this 1st Embodiment, by the relative rotational movement of the outer side cylinder 17 with which the upstream side blocking part 19 and the downstream side blocking part 20 were united with respect to the inner side cylinder 16, FIG. As shown in FIG. 4B, the upstream side communication hole 34 and the downstream side communication hole 35, the raw water inlet 37 and the outlet 39 are shifted from each other and the raw water inlet 21 and outlet 22 are closed. The upstream communication hole 34 and the downstream communication hole 35, the raw water inlet 37 and the outlet 39 are aligned with each other, and the raw water inlet 21 and outlet 22 are opened, as shown in FIG. It becomes possible to easily open and close the raw water inflow path 21 and the outflow path 22.

本第１実施形態によれば、外側筒体１７の開閉スライド部材２５と共に上記ロック機構を構成する切り欠き凹部２６は、図２（ａ），（ｂ）に示すように、外側筒体１７の下方に張り出して設けられた、下方基盤３３の外周部分である下方環状突壁３０の上端縁部を、例えば開閉スライド部材２５の幅と同等かこれよりも若干広い幅で、略矩形形状に下方に切り欠いて形成される。この切り欠き凹部２６には、スライド案内溝３１に沿って下方にスライド移動させた開閉スライド部材２５の下方突出部分２５ａが嵌合するように係止される。この状態では、外側筒体１７に開口形成された薬剤注入口２３及び空気孔３６と、開閉スライド部材２５に開口形成されたスライド注入口２４及びスライド空気孔４３とが互いに合致して、薬剤収容室１５の水抜きや、薬剤収容室１５への混合用薬剤の注入を行うことが可能になる（図４（ａ）参照）。またこの状態では、開閉スライド部材２５の下方突出部分２５ａが切り欠き凹部２６に係止して、外側筒体１７の周方向Ｙへの回転移動が確実に阻止されることになる。 According to the first embodiment, as shown in FIGS. 2 (a) and 2 (b), the notch recess 26 that constitutes the locking mechanism together with the opening / closing slide member 25 of the outer cylinder 17 is provided on the outer cylinder 17 as shown in FIGS. An upper end edge of the lower annular protruding wall 30 that is provided to project downward and is an outer peripheral portion of the lower base 33 is, for example, lower in a substantially rectangular shape with a width equal to or slightly wider than the width of the opening / closing slide member 25. Notched to be formed. The notch recess 26 is locked so that the downward projecting portion 25 a of the open / close slide member 25 slid downward along the slide guide groove 31 is fitted. In this state, the medicine injection port 23 and the air hole 36 formed in the outer cylindrical body 17 and the slide injection port 24 and the slide air hole 43 formed in the opening / closing slide member 25 are aligned with each other to store the medicine. It is possible to drain the chamber 15 and inject the mixing drug into the drug storage chamber 15 (see FIG. 4A). Further, in this state, the downward projecting portion 25a of the opening / closing slide member 25 is engaged with the notch recess 26, and the rotational movement of the outer cylindrical body 17 in the circumferential direction Y is reliably prevented.

開閉スライド部材２５及び切り欠き凹部２６と共に上記ロック機構を構成する切り欠き凹溝２８は、外側筒体１７の上方に張り出して設けられた、上方基盤３２の外周部分である上方環状突壁２９の下端縁部を、切り欠き凹部２６の直上部分から例えば開閉スライド部材２５の幅の１．５〜４倍程度の周方向Ｙの長さで上方に切り欠いて形成される。また切り欠き凹溝２８は、下方突出部分２５ａが切り欠き凹部２６から抜き出されるまで開閉スライド部材２５を上方にスライド移動できるような深さで設けられている。 A notch groove 28 that constitutes the locking mechanism together with the opening / closing slide member 25 and the notch recess 26 is formed on an upper annular protruding wall 29 that is an outer peripheral portion of the upper base 32 and is provided so as to protrude above the outer cylindrical body 17. The lower end edge is formed by notching upward from a portion directly above the notch recess 26, for example, in the circumferential direction Y of about 1.5 to 4 times the width of the opening / closing slide member 25. The notch groove 28 is provided with such a depth that the open / close slide member 25 can be slid upward until the downward projecting portion 25 a is extracted from the notch recess 26.

この切り欠き凹溝２８には、スライド案内溝３１に沿って上方にスライド移動させた、開閉スライド部材２５の上端部２５ｂにある遊嵌凸部２７が遊嵌し、当該切り欠き凹溝２８によって画定される領域内においてこの遊嵌凸部２７を周方向Ｙにスライドさせつつ、外側筒体１７を内側筒体１６に対して周方向Ｙに回転移動させることが可能になる。この状態では、外側筒体１７に開口形成された薬剤注入口２３及び空気孔３６と、開閉スライド部材２５に開口形成されたスライド注入口２４及びスライド空気孔４３とが互いにずれて閉塞することになる。また遊嵌凸部２７が切り欠き凹溝２８の右側端部に当接するまで外側筒体１７を回転移動することにより、上流側連通孔３４及び下流側連通孔３５と原水流入口３７及び流出口３９とが互いに合致して、原水を薬剤収容室１５に流入させることが可能になる（図４（ｂ）参照）。さらに、開閉スライド部材２５は、切り欠き凹部２６が設けられた位置から周方向Ｙにずれて、これの下端部２５ａが下方環状突壁３０の切り欠き凹部２６のない上端縁部に当接することにより、開閉スライド部材２５の下方へのスライド移動が確実に阻止されることになる。 A loose fitting convex portion 27 at the upper end portion 25 b of the open / close slide member 25, which is slid upward along the slide guide groove 31, loosely fits into the notched concave groove 28. The outer cylindrical body 17 can be rotated and moved in the circumferential direction Y with respect to the inner cylindrical body 16 while sliding the loose fitting convex portion 27 in the circumferential direction Y within the defined area. In this state, the medicine injection port 23 and the air hole 36 formed in the outer cylinder 17 and the slide injection port 24 and the slide air hole 43 formed in the opening / closing slide member 25 are shifted from each other and closed. Become. Further, by rotating and moving the outer cylindrical body 17 until the loose fitting convex portion 27 comes into contact with the right end portion of the notched concave groove 28, the upstream side communication hole 34, the downstream side communication hole 35, the raw water inlet 37 and the outlet are provided. 39 coincide with each other, and raw water can be allowed to flow into the medicine storage chamber 15 (see FIG. 4B). Further, the opening / closing slide member 25 is displaced in the circumferential direction Y from the position where the notch recess 26 is provided, and the lower end 25a of the opening / closing slide member 25 abuts on the upper end edge of the lower annular protruding wall 30 without the notch recess 26. Thus, the downward sliding movement of the opening / closing slide member 25 is surely prevented.

なお、本第１実施形態によれば、混合用アタッチメント１０には、図１及び図３に示すように、その上端部に、上方基盤３２を介してシャワー器具１１が装着されると共に、その下端部に、下方基盤３３を介して例えば脱塩素フィルターを備える浄水部４１が装着され、さらにこの浄水部４１にシャワー水供給ホース１２が接続される。 According to the first embodiment, as shown in FIGS. 1 and 3, the shower attachment 11 is mounted on the upper end portion of the mixing attachment 10 via the upper base 32 and the lower end thereof. A water purification unit 41 including, for example, a dechlorination filter is attached to the part via the lower base 33, and the shower water supply hose 12 is further connected to the water purification unit 41.

また、本第１実施形態によれば、薬剤収容室１５の上流側端部における原水流入路２１の収容室連通孔３８と接続して、流出路２２に向かう螺旋流を薬剤収容室１５内に生じさせる螺旋流発生手段が設けられている。すなわち、本第１実施形態によれば、螺旋流発生手段は、例えば円環状断面を有する薬剤収容室１５の下端部分に周方向Ｙに１８０度の間隔をおいて配置された一対の中空円筒突起４２からなるものである。これらの中空円筒突起４２は、例えば放流口を、各々円環状断面の薬剤収容室１５の周方向Ｙに沿った同じ回転方向に向けて横向きに開口させていることより、原水流入路２１から流入する原水を円環状断面の周方向Ｙに向けて放流口から放流させ、これによって薬剤収容室１５内に、流出路２２に向かう螺旋流を発生させるようになっている。 In addition, according to the first embodiment, the spiral flow toward the outflow passage 22 is connected to the storage chamber communication hole 38 of the raw water inflow passage 21 at the upstream end portion of the medicine storage chamber 15 in the medicine storage chamber 15. Spiral flow generating means for generating is provided. In other words, according to the first embodiment, the spiral flow generating means includes a pair of hollow cylindrical protrusions arranged at an interval of 180 degrees in the circumferential direction Y at the lower end portion of the medicine storage chamber 15 having an annular cross section, for example. 42. These hollow cylindrical protrusions 42 flow in from the raw water inflow passage 21 by opening the discharge port sideways in the same rotational direction along the circumferential direction Y of the medicine container 15 having an annular cross section, for example. The raw water to be discharged is discharged from the discharge port toward the circumferential direction Y of the annular cross section, thereby generating a spiral flow toward the outflow path 22 in the medicine containing chamber 15.

そして、上述の構成を有する本第１実施形態の混合用アタッチメント１０が取り付けられたシャワー器具１１を用いて、混合用薬剤を混合したシャワー水によるシャワーを行うには、まず薬剤収容室１５に所望量の混合用薬剤を注入する作業を行う。すなわち、混合用アタッチメント１０やシャワー器具１１が一体として取り付けられた、図１に示す薬剤散布器具を手で把持し、例えば親指を開閉スライド部材２５の***部２５ｃに密着係止して、遊嵌凸部２７が切り欠き凹溝２８の左側端部に当接するまで外側筒体１７を回転移動し、さらに開閉スライド部材２５を下方にスライド移動して、下方突出部分２５ａを切り欠き凹部２６に係止する。これによって、外側筒体１７の薬剤注入口２３及び空気孔３６と、開閉スライド部材２５のスライド注入口２４及びスライド空気孔４３とが合致するので、空気孔３６から空気を排除しつつ、薬剤注入口２３を介して薬剤収容室１５へ混合用薬剤をスムーズに注入してゆくことが可能になる。またこの注入作業の最中には、下方突出部分２５ａの切り欠き凹部２６への係止によって、外側筒体１７の回転移動が阻止されて、薬剤収容室１５に原水を流入させることがない。 In order to perform a shower with shower water mixed with a mixing agent, using the shower device 11 to which the mixing attachment 10 of the first embodiment having the above-described configuration is attached, first, a desired container is provided in the medicine storage chamber 15. Work to inject a quantity of drug for mixing. That is, the medicine spraying device shown in FIG. 1 to which the mixing attachment 10 and the shower device 11 are integrally attached is gripped by hand, and for example, the thumb is tightly locked to the raised portion 25c of the opening / closing slide member 25 to loosely fit. The outer cylindrical body 17 is rotationally moved until the convex portion 27 comes into contact with the left end portion of the notch groove 28, and the open / close slide member 25 is further slid downward, and the downward projecting portion 25a is engaged with the notch recess 26. Stop. As a result, the medicine injection port 23 and the air hole 36 of the outer cylindrical body 17 and the slide injection port 24 and the slide air hole 43 of the open / close slide member 25 are matched, so that the drug injection is performed while excluding air from the air hole 36. It is possible to smoothly inject the medicine for mixing into the medicine storage chamber 15 through the inlet 23. During this injection operation, the outer cylindrical body 17 is prevented from rotational movement by the locking of the downward projecting portion 25 a to the notch recess 26, so that the raw water does not flow into the medicine containing chamber 15.

薬剤収容室１５へ混合用薬剤を所望量注入したら、例えば上述と同様の親指の操作によって、開閉スライド部材２５を、その上端部２５ｂが切り欠き凹溝２８の左側端部の上縁部分に当接するまで上方にスライド移動させる。これによって、外側筒体１７の薬剤注入口２３及び空気孔３６と、開閉スライド部材２５のスライド注入口２４及びスライド空気孔４３とがずれて、薬剤注入口２３及び空気孔３６が閉塞され、注入された混合用薬剤が薬剤収容室１５から洩出することなく内部に収容された、薬剤散布までの待機状態となる。また、開閉スライド部材２５を上方にスライド移動させた後に、これの下端部２５ａが切り欠き凹部２６から周方向Ｙに外れるように外側筒体１７を僅かに回転移動させることにより、かかる待機状態において、開閉スライド部材２５が下方に移動して混合用薬剤が洩出するのを効果的に回避することが可能になる。 When a desired amount of the medicine for mixing is injected into the medicine storage chamber 15, the opening / closing slide member 25 is applied to the upper edge portion of the left end portion of the notch groove 28 with the upper end portion 25b thereof, for example, by the same thumb operation as described above. Slide it up until it touches. As a result, the drug injection port 23 and the air hole 36 of the outer cylindrical body 17 and the slide injection port 24 and the slide air hole 43 of the open / close slide member 25 are displaced, and the drug injection port 23 and the air hole 36 are closed and injected. The mixed medicine thus prepared is accommodated inside without leaking from the medicine accommodating chamber 15 and is in a standby state until the medicine is sprayed. Further, after sliding the open / close slide member 25 upward, the outer cylindrical body 17 is slightly rotated so that the lower end portion 25a of the open / close slide member 25 is detached from the notch recess 26 in the circumferential direction Y. Thus, it is possible to effectively prevent the mixing medicine from leaking due to the opening / closing slide member 25 moving downward.

そして、このような待機状態から、使用者が、例えば入浴の仕上げとしてシャワー水と共に混合用薬剤を身体に散布する際には、例えばシャワーを行いつつ上述と同様の親指の操作によって、開閉スライド部材２５の遊嵌凸部２７が切り欠き凹溝２８の右側端部に当接するまで外側筒体１７を回転移動する。これによって、上流側連通孔３４及び下流側連通孔３５と原水流入口３７及び流出口３９とが互いに合致し、原水を薬剤収容室１５に流入させると共に、混合用薬剤を原水に混合させて下流側流路１４に流出させることが可能になり、シャワー水と共に混合用薬剤を身体に散布することができる。 When the user sprays the medicine for mixing with shower water on the body, for example, as a finish of bathing from such a standby state, for example, by performing the same thumb operation as described above while performing a shower, The outer cylindrical body 17 is rotationally moved until the 25 loose fitting convex portions 27 abut on the right end portion of the cutout concave groove 28. As a result, the upstream side communication hole 34 and the downstream side communication hole 35 and the raw water inlet 37 and the outlet 39 coincide with each other, and the raw water flows into the medicine storage chamber 15 and the mixing chemical is mixed with the raw water to the downstream. It becomes possible to make it flow into the side flow path 14, and can mix the chemical | medical agent for mixing with a shower water on a body.

シャワーが終了したら、例えば上述と同様の親指の操作によって、外側筒体１７を反対側に回転移動して遊嵌凸部２７を切り欠き凹溝２８の左側端部に当接させ、さらに下方突出部分２５ａが切り欠き凹部２６に係止するまで開閉スライド部材２５を下方にスライド移動させる。これによって、外側筒体１７の薬剤注入口２３及び空気孔３６と、開閉スライド部材２５のスライド注入口２４及びスライド空気孔４３とが合致して、混合用薬剤と入れ替わった原水が薬剤注入口２３を介して薬剤収容室１５から水抜きされ、薬剤収容室１５へ混合用薬剤を注入してゆくことが可能な状態に復帰することになる。 When the shower is finished, for example, by the same thumb operation as described above, the outer cylindrical body 17 is rotationally moved to the opposite side so that the loosely fitting convex portion 27 is brought into contact with the left end of the concave groove 28 and further protrudes downward. The open / close slide member 25 is slid downward until the portion 25a engages with the notch recess 26. As a result, the drug injection port 23 and the air hole 36 of the outer cylindrical body 17 and the slide injection port 24 and the slide air hole 43 of the open / close slide member 25 are matched, and the raw water replaced with the mixing drug is the drug injection port 23. Thus, water is drained from the medicine container 15 and the mixture medicine returns to a state in which the medicine for mixing can be injected into the medicine container 15.

したがって、本第１実施形態の混合用アタッチメント１０、又はこの混合用アタッチメント１０を取り付けた薬剤散布器具によれば、例えば親指による簡単な操作によって、薬剤注入口２３の開閉操作、及び薬剤収容室１５への原水流入路２１や流出路２２の開閉操作を容易且つスムーズに行うことができると共に、薬剤注入口２３を開放したまま薬剤収容室１５へ原水が流入するのを確実に回避することができ、且つ取り扱い易さを向上させることが可能になる。 Therefore, according to the mixing attachment 10 of the first embodiment or the medicine spraying device to which the mixing attachment 10 is attached, for example, the opening / closing operation of the medicine inlet 23 and the medicine storage chamber 15 can be performed by a simple operation with the thumb. The raw water inflow passage 21 and the outflow passage 22 can be opened and closed easily and smoothly, and the raw water can be reliably prevented from flowing into the medicine storage chamber 15 with the medicine inlet 23 open. And it becomes possible to improve the ease of handling.

また、本第１実施形態によれば、外側筒体１７は、開閉スライド部材２５を上下にスライド移動させるスライド案内溝３１が設けられた５〜２０ｍｍ程度の幅の帯状部分を除いて、その略全体を一重構造とすることができ、薬剤収容室の外側に周方向Ｙに回転移動可能なスリーブ部材を設けて二重構造とした場合とは違って、薬剤収容室の外周面とスリーブ部材の内周面との間の隙間に混合用薬剤や原水が侵入してカビやぬめり、水垢等の汚れが発生するのを抑制することができる。また開閉スライド部材２５は、外側筒体１７の外周面に沿って上下方向にのみスライド移動し、周方向Ｙへはスライド移動しないので、スライド案内溝３１との間の隙間を極僅かなものとすることができ、これによって、カビやぬめり、水垢等の汚れの発生をさらに抑制できる。 Further, according to the first embodiment, the outer cylindrical body 17 is substantially the same except for a belt-like portion having a width of about 5 to 20 mm provided with a slide guide groove 31 for sliding the open / close slide member 25 up and down. Unlike the case where a double structure is provided by providing a sleeve member that can be rotated and moved in the circumferential direction Y outside the drug storage chamber, the entire outer surface of the drug storage chamber and the sleeve member It is possible to prevent the mixing agent and raw water from entering the gap between the inner peripheral surface and the occurrence of dirt such as mold, slime, and scale. Further, since the open / close slide member 25 slides only in the vertical direction along the outer peripheral surface of the outer cylindrical body 17 and does not slide in the circumferential direction Y, the gap between the slide guide groove 31 and the slide guide groove 31 is extremely small. As a result, it is possible to further suppress the occurrence of dirt such as mold, slime and scale.

さらに、本第１実施形態によれば、外側筒体１７は、その略全体を一重構造とすることができるので、外側筒体１７を透明な部材によって形成しても、二重構造の隙間に蒸気等が侵入して曇ることになるのを回避することができ、これによって薬剤収容室１５の内部の混合用薬剤の残量等を容易に確認することができる。 Furthermore, according to the first embodiment, the outer cylindrical body 17 can be formed substantially in a single structure. Therefore, even if the outer cylindrical body 17 is formed of a transparent member, the outer cylindrical body 17 has a double structure gap. It is possible to avoid vapor and the like from entering and becoming cloudy, whereby the remaining amount of the mixing medicine in the medicine storage chamber 15 can be easily confirmed.

なお、本発明は上記第１実施形態に限定されることなく種々の変更が可能である。例えば、本発明の混合用アタッチメントは、シャワー水に浴用薬剤やスキンケア用薬剤等の身体用薬剤を混合して送り出すものに限定されることなく、シャワー器具以外のその他の薬剤散布器具に取り付けて、各種の液状、ゲル状、粒状、固形状等の家庭用消費薬剤や農業用薬剤等の薬剤を原水に混合するために採用することもできる。また、薬剤収容室の内部に螺旋流を生じさせる螺旋流発生手段は設けても設けなくても良く、内側筒体に対して外側筒体を回転操作して流入路及び流出路を開閉する機構は、上述の開閉機構に限定されるものではない。さらに、混合用アタッチメントは、シャワー器具とシャワー水供給ホースとの間に介在させて取り付ける必要は必ずしもなく、シャワー器具の外部から見えないように当該シャワー器具に内蔵させて取り付けることもできる。さらにまた、開閉スライド部材は、スライド案内溝に填め込まれて当該スライド案内溝に沿って軸方向にスライド移動するものでなくても良い。 The present invention is not limited to the first embodiment, and various modifications can be made. For example, the mixing attachment of the present invention is not limited to the one that mixes and sends out body medicine such as bath medicine or skin care medicine into shower water, and is attached to other medicine spraying equipment other than shower equipment, Various liquids, gels, granules, solids, etc., such as household consumption drugs and agricultural chemicals can also be used for mixing with raw water. In addition, a spiral flow generating means for generating a spiral flow inside the drug storage chamber may or may not be provided, and a mechanism for rotating the outer cylinder relative to the inner cylinder to open and close the inflow path and the outflow path. Is not limited to the above-described opening / closing mechanism. Further, the mixing attachment is not necessarily required to be interposed between the shower device and the shower water supply hose, and can be attached to the shower device so that it cannot be seen from the outside of the shower device. Furthermore, the opening / closing slide member may not be inserted into the slide guide groove and slide in the axial direction along the slide guide groove.

また、薬剤注入口とスライド注入口とを合致させた状態では内側筒体に対する外側筒体の回転移動を阻止し、原水流入路や流出路が開放された状態では開閉スライド部材のスライド移動を阻止するロック機構として、上記第１実施形態のものに限定されることなくその他の種々のロック機構を採用することができる。例えば、図５（ａ）に示すように、開閉スライド部材２５の突出部分を係止する切り欠き凹部２６を、上方環状突壁２９の下端縁部を切り欠いて形成し、遊嵌凸部２７を遊嵌する切り欠き凹溝２８を下方環状突壁３０の上端縁部を切り欠いて形成することもできる。また、図５（ｂ）に示すように、切り欠き凹溝２８を、外側筒体１７の上端縁部又は下端縁部を切り欠いて形成し、遊嵌凸部２７を、上方環状突壁２９の下端縁部又は下方環状突壁３０の上端縁部から突出する部分としても良い。 In addition, when the drug inlet and the slide inlet are matched, the outer cylinder is prevented from rotating relative to the inner cylinder, and the open / close slide member is prevented from sliding when the raw water inlet and outlet paths are open. The locking mechanism to be used is not limited to that of the first embodiment, and various other locking mechanisms can be employed. For example, as shown in FIG. 5A, a notch recess 26 that locks the projecting portion of the opening / closing slide member 25 is formed by notching the lower end edge of the upper annular projecting wall 29, and the loose fitting projection 27. A notch groove 28 for loosely fitting the upper annular edge 30 can also be formed by notching the upper notch. Further, as shown in FIG. 5 (b), the notch groove 28 is formed by notching the upper end edge or the lower end edge of the outer cylindrical body 17, and the loose fitting convex portion 27 is formed by the upper annular protruding wall 29. It is good also as a part which protrudes from the lower end edge part of this, or the upper end edge part of the lower annular protrusion wall 30. FIG.

さらに、図５（ｃ）に示すように、切り欠き凹溝２８は、上方環状突壁２９、下方環状突壁３０又は外側筒体１７の上端縁部又は下端縁部の内側を、外側表面部分を残して（外側表面部分に切り欠き凹溝２８を形成するのではなく）切り欠くことによって形成し、この内側部分の切り欠き凹溝２８に、対向する上端縁部又は下端縁部の内側部分から突出させた遊嵌凸部２７を遊嵌させるようにすることもできる。このように、切り欠き凹溝２８を外側表面部分を残して（外側表面部分に切り欠き凹溝２８を形成するのではなく）内側部分に形成することにより、切り欠き凹溝２８及び遊嵌凸部２７を当該外側表面部分で覆い隠して、これらがシャワー器具や薬剤散布器具の外部から見えないようにすることができ、これによってデザイン性を向上させることが可能になる。また切り欠き凹溝２８と遊嵌凸部２７による回転機構を内側に設けることによって、汚れやカビの発生をさらに低減させることが可能になる。 Further, as shown in FIG. 5 (c), the notch groove 28 is formed on the inside of the upper or lower end edge of the upper annular protrusion wall 29, the lower annular protrusion wall 30 or the outer cylindrical body 17, and the outer surface portion. Is formed by notching (instead of forming the notch groove 28 in the outer surface portion), and the notch groove 28 of the inner portion is formed in the inner portion of the opposite upper end edge or lower end edge portion. It is also possible to loosely fit the loosely protruding convex portion 27 protruding from the protrusion. Thus, by forming the notch groove 28 in the inner portion leaving the outer surface portion (rather than forming the notch groove 28 in the outer surface portion), the notch groove 28 and the loose fitting convexity are formed. The portion 27 can be covered with the outer surface portion so that they cannot be seen from the outside of the shower device or the medicine spraying device, thereby improving the design. Further, by providing a rotation mechanism with the notch concave groove 28 and the loosely fitting convex portion 27 on the inner side, it becomes possible to further reduce the occurrence of dirt and mold.
