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.

  Further, in the upstream blocking portion 19 and the downstream blocking portion 20, the raw water inflow channel (branch channel) 21 and the outflow channel (branch channel) are formed so as to pass through the central portion of the cross section concentrically and in an annular shape. ) 22 are formed extending along the circumferential direction Y, respectively. 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. An inflow port 37 (see FIG. 3B) 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.

  On the other hand, in the downstream side blocking portion 20 in which the outflow path 22 is formed, the outer peripheral surface of the inner cylinder 16 is placed at a specific position in the circumferential direction Y that can match the downstream communication hole 35 of the inner cylinder 16.

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.

  And according to this embodiment, as shown to Fig.3 (a) 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 with respect to the inner side cylinder 16 were united. As shown in FIG. 3B, the upstream communication hole 34 and the downstream communication hole 35, the inlet 37 and the outlet 39 are displaced from each other and the raw water inlet 21 and outlet 22 are closed. The raw water inflow passage 21 is switched by switching the upstream communication hole 34 and the downstream communication hole 35 to the state in which the inlet 37 and the outlet 39 coincide with each other and the raw water inflow passage 21 and the outflow passage 22 are opened. And the opening / closing operation of the outflow passage 22 can be easily performed.

  According to this embodiment, the fluidizers 50a and 50b accommodated in the medicine accommodating chamber 15 are plastic spherical members (solid members) having a diameter of 3 to 10 mm, for example, and the specific gravity is, for example, 1.0. A total of four first fluidizers and two second fluidizers having a specific gravity of 1.7, for example, are accommodated.

  Here, according to the present invention, the shape of the fluidizer disposed inside the drug storage chamber may be, for example, an egg shape, a bead shape, a cylindrical (columnar) shape, a disk shape, a rectangular flat plate shape, a cube in addition to a spherical shape. Various other shapes such as a shape and a hexahedron shape can be used. In addition, the fluidizer may be either solid or non-solid, and has a size such that the maximum external dimension is about 3 to 10 mm, for example. The apparent specific gravity is preferably about 1 to 3 times the specific gravity of the mixing drug stored in the drug storage chamber or the raw water flowing into the drug storage chamber. The fluidizer related to the mixing attachment according to the present invention is caused to move up, down, left and right while colliding with the wall surface or colliding with each other in the drug storage chamber by the action of the water flow from the inlet to the outlet. It moves freely (moves).

  In addition, in the attachment for mixing according to the present invention, if the number of fluidizers used is the same, the agent remaining rate is lower when a larger fluidizer is used. Note that the relationship between the size of the fluidizer and the width of the medicine storage chamber will be described. For example, the clearance C between the inner cylinder 16 and the outer cylinder 17 (see FIGS. 3A and 3B) is described in the following. When the spherical fluidizers 50a and 50b having a diameter of 4 mm (60% of clearance C) to 6 mm (95% of the same) are used when 3 mm (minimum part) to 6.54 mm are used, the reduction in the residual agent rate is good. In addition, the size of the fluidizer was within a preferable range.

  Furthermore, according to this embodiment, the attachment 10 for mixing is provided with the turbulent flow generation | occurrence | production means which produces the flow of irregular water in the chemical | medical agent storage chamber 15, By this, the inside of the chemical | medical agent storage chamber 15 is provided in the whole. In addition, the fluidizers 50a and 50b can be moved more randomly. That is, as shown in FIG. 4, for example, the turbulent flow generating means shifts the discharge wings 53 having the circumferential discharge ports 52 formed in the notch surfaces 51 facing in the circumferential direction by 180 degrees in the circumferential direction at two locations. The arranged spiral flow generating means and the axial discharge port 54 which is opened upward in the vicinity of the outer peripheral surface of the discharge vane 53 at two positions shifted from the respective cutout surfaces 51 by 90 degrees in the circumferential direction. And an axial discharge means.

  The circumferential discharge port 52 of the spiral flow generating means and the axial discharge port 54 of the axial discharge means communicate with the raw water inflow passage 21 through the accommodation chamber communication hole 38 of the upstream side blocking portion 19, respectively. When the inlet 37 and the outlet 39 are opened, the raw water is discharged simultaneously in the spiral direction and the axial direction by the pressure of the raw water flowing into the raw water inflow path 21. As a result, an irregular flow (turbulent flow) in which the spiral flow and the axial flow are mixed can be easily generated in the medicine containing chamber 15.

  Further, according to the present embodiment, the mixing attachment 10 slides the open / close slide member 25 in the axial direction X as shown in FIGS. 3 (a) and 3 (b) and FIGS. 5 (a) and 5 (b). When the drug injection port 23 and the slide injection port 24 are matched (see FIGS. 3A and 5A), the outer cylinder 17 rotates in the circumferential direction Y with respect to the inner cylinder 16. In the state where the outer cylinder 17 is rotated and moved to open the raw water inflow path 21 and the outflow path 22 (see FIGS. 3B and 5B), the axial direction X of the open / close slide member 25 A locking mechanism is provided to prevent the sliding movement to.

  That is, the open / close slide member 25 is attached so as to be slidably movable downward from the lower end edge of the outer cylindrical body 17, and the lock mechanism is provided below the open / close slide member 25 and the outer cylindrical body 17. A notch recess 26 that locks the downward projecting portion 25a that is the lower end portion of the opening / closing slide member 25, a loose fitting convex portion 27 provided above the outer cylindrical body 17, and the loose fitting convex portion 27 in the circumferential direction Y. And a cut-out concave groove 28 that is slidably fitted to be slidable. Then, the medicine injection port 23 and the slide injection port 24 are matched with each other in a state where the downward projecting portion 25a of the opening / closing slide member 25 is notched and locked to the recess 26 (see FIG. 5A), and this locked state is set. By rotating the outer cylindrical body 17 until the loosely fitting convex portion 27 is opened and abuts one end (right side) of the notched concave groove 28 (see FIG. 5B), the raw water inflow passage 21 and the outflow The path 22 is opened.

  Further, according to the present embodiment, the outer cylindrical body 17 is disposed between the upper annular projecting wall 29 and the lower annular projecting wall 30 provided above and below the outer cylindrical body 17 and against these. The notched recess 26 is formed by cutting out the upper edge of the lower annular protruding wall 30, and the notched groove 28 is formed at the lower edge of the upper annular protruding wall 29. It is formed by cutting away.

  Furthermore, according to the present embodiment, the slide guide groove 31 extending in the axial direction X of the outer cylinder 17 is formed on the peripheral surface of the outer cylinder 17, and the open / close slide member 25 is provided with this slide guide. It is inserted into the groove 31 and slides in the axial direction X along the slide guide groove 31.

  In order to perform a shower using shower water mixed with a mixing agent, using the shower device 11 to which the mixing attachment 10 of the present embodiment having the above-described configuration is attached, first, a desired amount is stored in the drug containing chamber 15. Work to inject the 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 match each other. It is possible to smoothly inject a mixing drug having a viscosity of, for example, about 2000 to 30000 mPa · sec through the inlet 23 into the drug storage chamber 15. 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. In addition, the measurement conditions of the viscosity of the chemical | medical agent for mixing were used apparatus: BM type | mold viscometer (made by Tokyo Seiki Co., Ltd.), rotor: No. 4. Rotation speed: 12 rpm, measurement time: 60 seconds, measurement temperature: 25 ° C.

  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.

  From such a standby state, when the user sprays the mixing agent together with shower water, for example, as a bathing finish, for example, by performing the same thumb operation as described above while performing a shower, The outer cylindrical body 17 is rotated until the loosely fitting convex portion 27 comes into contact with the right end portion of the notched concave groove 28. As a result, the upstream communication hole 34 and the downstream communication hole 35 and the inflow port 37 and the outflow port 39 are matched with each other, and the raw water flows into the medicine storage chamber 15 and the mixing chemical is mixed with the raw water. It becomes possible to make it flow out to the path | route 14, for example, and to mix | blend the chemical | medical agent for mixing with a shower water on a body until the chemical | medical agent for mixing runs out for 10 to 60 seconds.

  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. Then, the water is extracted from the medicine storage chamber 15, and the state returns to a state in which the medicine for mixing can be injected into the medicine storage chamber 15.

  And according to this embodiment, even when a medicine with the above-mentioned viscosity is used as a medicine for mixing, or even when the raw water flowing into the medicine storage chamber 15 has a low amount of water, a medicine residue is generated. It is possible to efficiently use the mixing medicine contained in the medicine storage chamber 15 while suppressing the medicine continuously at a desired concentration for a desired time and mixing it with raw water in a stable state. Become.

  That is, according to the present embodiment, the fluidizers 50a and 50b floating inside the medicine storage chamber 15 by the action of the water flow from the inlet 37 to the outlet 39 are accommodated. , 50b move freely up and down and left and right so as to appear inside the medicine storage chamber 15, for example, by scraping off the medicine in the vicinity of the wall surface where the flow velocity is slow while colliding with the wall surface of the medicine storage chamber 15, for example. Thus, it becomes possible to release the drug for mixing while suppressing the remaining agent.

  Moreover, according to this embodiment, since two types of fluidizers 50a and 50b having different specific gravity and shape are accommodated in the medicine accommodating chamber 15, the function of scraping off the medicine in the vicinity of the wall surface is remarkably exhibited. It will be.

  Furthermore, according to the present embodiment, the mixing attachment 10 includes the turbulent flow generation means including the spiral flow generation means and the axial direction discharge means. It is possible to easily form the fluidizers 50a and 50b so that the fluidizers 50a and 50b can be further randomized and exposed, and the above-described functions can be exhibited more remarkably.

  Moreover, although the single fluidizer accommodated in a chemical | medical agent storage chamber can also be used, it is good to use 2 or more. In that case, a combination of two or more kinds of fluidizers having different specific gravity, shape, or size is even better.

  The present invention is not limited to the above-described 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. Further, the mixing attachment need not necessarily be interposed between the shower device and the shower water supply hose, and can be mounted in the shower device so that it cannot be seen from the outside of the shower device.
