Description

  The present invention relates to a mixing attachment that mixes a mixing medicine accommodated in a medicine storage chamber with raw water and flows it out together with the raw water, and a medicine spraying device to which the mixing attachment is integrally attached.

  For example, in a spraying device such as a shower device, a chemical such as a bathing agent is added and mixed as a mixing agent to the raw water supplied via a pipe such as a hose, and the raw water can be sprayed from the spraying device together with the mixing agent. An attached attachment is disclosed (for example, see Patent Document 1 and Patent Document 2).

  As shown in FIG. 7, the attachment described in Patent Document 1 includes a double structure in which an internal container 61 serving as a medicine storage chamber is provided inside an external container 60. It is used by attaching to the spraying equipment. The mixing agent is stored in the inner container 61. The valve 63 provided at the liquid inlet 62 of the inner container 61 is opened and closed to allow the raw water to flow into the inside, and the mixing chemical is dissolved by the flowing raw water. Alternatively, by diluting the raw water through the outlet 64 that is always open while diluting and joining the raw water passing through the raw water flow path 65, the raw water can be sprayed from the spraying device in a state where the mixing agent is added and mixed. It is what you want to do.

The attachment described in Patent Document 2 includes a double structure including an inner cylinder and an outer cylinder, and the inside of the inner cylinder serves as a main water passage (raw water channel), and the inner cylinder and the outer cylinder. A secondary water passage (drug storage chamber) is formed between the body and the inside of the drug storage chamber is filled with a solidified cosmetic agent eluted by water. Then, according to the attachment described in Patent Document 2, the raw water is introduced into the medicine storage chamber through the water passage hole of the water distribution plate, and the outlet that is always open while the cosmetic agent solidified by the introduced raw water is eluted. It is discharged from the water and flows down together with the raw water flowing through the main channel.

  On the other hand, for example, when an attachment for mixing medicine is attached to a shower device, it is preferable to keep the medicine mixed in the shower water at a desired concentration and to release the medicine continuously for a desired time. In addition, it is preferable that the medicine stored in the medicine storage chamber is used up in a desired time without leaving the medicine, and the medicine can be efficiently sprayed.

  However, according to the conventional attachment for mixing drugs, for example, when a drug having a viscosity of about 2000 to 30000 mPa · sec is stored in the drug storage chamber, or when the raw water flowing into the drug storage chamber is low in volume (3 L / In the case of using a powdered medicine or the like, the medicine in the medicine containing chamber becomes difficult to be mixed with raw water, and the medicine in the vicinity of the wall of the medicine containing room where the flow rate is slow is gradually released. It becomes easy to produce the agent residue without. And, when using an attachment over a long period of time due to such drug residue or accumulation of the drug residue, the attachment becomes dirty and the inside becomes difficult to see, and the appearance becomes poor and waste of the drug occurs. In addition, the desired desired sustained release time cannot be sufficiently secured, and the effect of the drug cannot be sufficiently obtained.

  The present invention effectively suppresses the generation of a residual agent even when, for example, a high-viscosity drug is used, when the raw water flowing into the drug storage chamber is low, or when a powdered drug is used. A mixing attachment capable of efficiently using the mixing agent stored in the storage chamber and mixing the raw drug with raw water while continuously releasing the drug at a desired concentration for a desired time, and the mixing attachment attached The purpose is to provide a chemical spraying device.

  The present invention has an inner cylindrical body and an outer cylindrical body, the inside of the inner cylindrical body is used as a raw water main flow path, and the hollow portion between the inner cylindrical body and the outer cylindrical body is disposed upstream at both ends. A mixing attachment that is covered with a side blocking portion and a downstream blocking portion to form a medicine storage chamber having an annular cross section, and the mixing agent stored in the drug storage chamber is mixed with the raw water and flows out together with the raw water. The drug storage chamber stores at least two kinds of fluidizers having different specific gravity, which move inside the drug storage chamber by the action of the flow of water flowing from the raw water main channel through the branch channel, The one or more kinds of the fluidizers are symmetrical with respect to the center of gravity, and the length in the diagonal direction connecting the peripheral edges of the pair of end faces is longer than the width in the radial direction of the drug storage chamber. Without changing the contact surface inside Mixing attachment to floating within the housing chamber, and by providing a chemical spraying device fitted integrally to the mixing attachment is obtained by achieving the above object.

  According to the mixing attachment or the medicine spraying device of the present invention, for example, even when a high viscosity medicine is used, the raw water flowing into the medicine storage chamber is low, or even when a powdered medicine is used, the residual medicine remains. It is possible to effectively suppress the generation and use the mixing drug stored in the drug storage chamber, and to mix it with the raw water while continuously releasing the drug at a desired concentration for a desired time.

  As shown in FIG. 1, the mixing attachment 10 according to a preferred embodiment of the present invention is attached, for example, between a shower device 11, which is a spray device, and a shower water supply hose 12. While showering chemicals such as bathing chemicals, cleaning chemicals, perfume chemicals, skin care chemicals, etc. are added and mixed in a shower water, they are allowed to flow down toward the shower device 11 on the downstream side, and shower water is added and mixed with these chemicals. The shower apparatus 11 is employed to be able to be used as a medicine spraying apparatus. That is, the mixing attachment 10 of the present embodiment is made of, for example, a synthetic resin. For example, each time a user uses a shower for bathing, a desired amount (drug of the drug) is stored in the drug storage chamber 15 (see FIG. 2). Inject and fill the mixing agent at a usage rate of 5 to 25 g at one time. As a bathing finish, for example, for about 10 to 60 seconds, the mixing agent is gradually released and the shower water is sprayed on the body, and the mixing is performed. It is used for the purpose of adhering drugs for use on the body so that the effects of these drugs can be obtained.

  And the attachment 10 for mixing of this embodiment is shown in FIG.2 and FIG.3 (a), (b), the raw water main flow path (upstream flow path) 13 by the side of the shower water supply hose 12 and the shower apparatus 11 The mixing chemical contained in the chemical containing chamber 15 is provided upstream from the raw water main flow channel (downstream flow channel) 14 on the upstream side through the inlet 37 (see FIG. 3B). It is an attachment that mixes with the raw water flowing in from the flow path 13 and flows the mixed solution diluted with the mixing agent together with the raw water to the downstream flow path 14 through the outlet 39 (see FIG. 3B). The inner cylindrical body 16 and the outer cylindrical body 17 are provided, and the inner side of the inner cylindrical body 16 is used as a raw water main flow path 18, and a hollow portion between the inner cylindrical body 16 and the outer cylindrical body 17 is formed. A medicine with an annular cross-section covering both ends with an upstream blocking portion 19 and a downstream blocking portion 20 A storage chamber 15, while mixing the mixed agent accommodated in the medicine accommodating chamber 15 to the raw water, so as to flow out together with the raw water.

  Further, at least two types having different specific gravity are floated in the medicine storage chamber 15 by the action of water flowing from the raw water main channel 18 through the raw water inflow channel (branch channel) 21 into the drug storage chamber 15. Fluidizers 50a and 50b (in this embodiment, two or three types of fluidizers, preferably a total of three to six) are accommodated, as shown in FIGS. 4 (a) and 4 (b). One or more (two or three types in this embodiment) fluidizers 50a, 50b, 50c are symmetrical with respect to the center of gravity, and are diagonally long connecting the peripheral edges of the pair of end faces 55, 55. Since the length d is longer than the radial width c of the medicine storage chamber 15, the contact surface (the end surfaces 55 and 55 in this embodiment) does not change inside the medicine storage chamber 15, and the inside of the medicine storage chamber. It comes to play with.

  In the present embodiment, one or more types (two or three types in the present embodiment) of the fluidizers 50a, 50b, and 50c are a pair of end surfaces 55, 55 and a side peripheral surface between the end surfaces 55, 55. 56 and is housed in the medicine containing chamber 15 with one end face 55 facing outward in the radial direction of the annular cross section, as described above. Since the diagonal length d connecting the peripheral edges of the pair of end surfaces 55, 55 is longer than the radial width c of the medicine storage chamber 15, one end surface 55 is directed radially outward of the annular cross section. The inside of the medicine storage chamber 15 is allowed to float while maintaining the above state.

  Further, in the present embodiment, the fluidizers 50a, 50b, and 50c have a height as a columnar shape having a low height including a pair of end surfaces 55 and 55 and a side peripheral surface 56 between the end surfaces 55 and 55. Each of the fluidizers 50a, 50b and 50c has two or three types of fluidizers having different specific gravities.

  As shown in FIG. 2 and FIGS. 3A and 3B, the inner cylinder 16 constituting the mixing attachment 10 of the present embodiment includes an upper base 32 having a disk donut shape and a lower base 33 having a disk donut shape. The inner raw water main flow path 18 is a raw water main flow path on the shower device 11 side through the central through holes 32a and 33a of the upper base 32 and the lower base 33. It communicates with the downstream flow path 14 and the upstream flow path 13 which is the raw water main flow path on the shower water supply hose 12 side. An upstream side communication hole 34 and a downstream side communication hole 35 are provided on the peripheral surface of the lower side and the upper side of the inner side cylindrical body 16 by the upstream side blocking part 19 and the downstream side blocking part 20. They are formed by being vertically arranged at the same position in the circumferential direction Y so as to penetrate the circumferential wall in the lateral direction.

  The outer cylindrical body 17 is preferably a sleeve-shaped member made of a transparent synthetic resin, and an upstream side blocking portion 19 and a downstream side blocking portion 20 are provided between the lower end portion and the upper end portion with the inner cylindrical body 16. Each is interposed and attached to the inner cylinder 16 so as to be rotatable in the circumferential direction Y (see FIG. 6B). Thereby, inside the outer cylinder 17, there is an annular cross-section medicine storage chamber 15 surrounded by the outer cylinder 17, the inner cylinder 16, the upstream blocking part 19 and the downstream blocking part 20. Will be formed.

  According to the present embodiment, the outer cylinder 17 is provided with the medicine injection port 23 to the drug storage chamber 15 on the peripheral surface at the lower portion thereof, and the drug injection port 23 also serves as a drainage port. An air hole 36 is formed in the upper portion of the outer cylinder 17 so as to be positioned vertically above the drug injection port 23. Then, the open / close slide member 25 having the slide inlet 24 and the slide air hole 43 that can coincide with the medicine inlet 23 and the air hole 36 is slid in the axial direction X of the outer cylinder 17. It is attached so as to be possible (see FIGS. 6A and 6B).

  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.

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.

  Further, in the upstream side blocking part 19 and the downstream side blocking part 20 in the shape of a disk donut, the raw water inflow channel (branch channel) 21 and the outflow are formed so as to penetrate the central part of the cross section concentrically and in an annular shape. Channels (branch water channels) 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 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 outflow port 39 (see FIG. 3B) is formed so as to open in the same direction as the inflow port 37 so as to penetrate 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.

  And according to this embodiment, it shows 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 were united with respect to the inner side cylinder 16. FIG. FIG. 3B shows a state in which 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 channel is switched between the upstream communication hole 34 and the downstream communication hole 35, the inlet 37 and the outlet 39, and the raw water inflow channel 21 and the outflow channel 22 being opened. It is possible to easily perform the opening / closing operation of 21 and the outflow path 22.

  According to this embodiment, the fluidizers 50a, 50b, and 50c accommodated in the medicine accommodating chamber 15 are made of, for example, plastic, and a pair of end surfaces on both sides as shown in FIGS. 55, 55 has a diameter (diameter) of about 4.5 to 12 mm, and a height b of the side peripheral surface 56 sandwiched between the pair of end surfaces 51 and 51 is about 3 to 4.7 mm. It is a member having a columnar shape or a substantially cylindrical shape with a low b. Moreover, the specific gravity of the fluidizers 50a, 50b, and 50c is preferably about 1 to 3 times the specific gravity of the mixing drug stored in the drug storage chamber 15 or the raw water flowing into the drug storage chamber 15. In this case, for example, the specific gravity of the fluidizer 50a is 1.0, the specific gravity of the fluidizer 50b is 1.1, and the specific gravity of the fluidizer 50c is 1.3.

  The fluidizers 50a, 50b, and 50c are located in the vicinity of the inner wall surface while colliding with the inner wall surface of the outer cylindrical body 17 in the medicine containing chamber 15 by the action of the water flow from the inlet 37 to the outlet 39. The drug is moved freely (moved) so as to be lifted up, down, left and right while being gradually released by scraping off the drug of the part.

  In the present embodiment, the fluidizers 50 a, 50 b, and 50 c have diagonal lengths d (see FIG. 4B) connecting the peripheral edges of the pair of columnar end surfaces 55 in the radial direction of the medicine container 15. By being longer than the width c (see FIG. 4 (a)), one end face 55 is kept inside the medicine container 15 while keeping the one end face 55 radially outward of the medicine container 15 having an annular cross section. Since it floats, the contact surface is not replaced by the one end surface 55 that becomes a contact surface by being opposed to the inner wall surface of the outer cylindrical body 17 and the peripheral corners thereof, and the medicine container 15 is efficiently replaced. It becomes possible to release the contained medicine gradually. In the state where one end face 55 is directed outward in the radial direction of the medicine storage chamber 15 having an annular cross section, one end face 55 is accurately disposed in the radial direction from the center of the annular cross section. In addition, one end face 55 faces a direction that is considerably deviated from the radial direction from the center of the annular cross section in a range in which the side peripheral surface 52 of the fluidizer 50a, 50b, 50c is not opposed to the inner wall surface of the outer cylindrical body 17. It is also included in the state of being arranged.

  In the present embodiment, two or three different specific gravity fluids 50a, 50b, and 50c are accommodated in the medicine accommodating chamber 15, and these fluids 50a, 50b, and 50c are inflow ports 37. By the action of the flow of water from the outlet 39 to the outlet 39, the medicine storage chamber 15 is floated in a state of being distributed and held in two or three divided areas approximately evenly up and down without causing a bias. It is possible to efficiently and slowly release the drug over substantially the entire drug storage chamber 15.

  Furthermore, in this embodiment, the larger the size of the fluidizers 50a, 50b, and 50c, the greater the effect of scraping off the drug. Since the effect of scraping the medicine is reduced, the width c in the radial direction of the medicine storage chamber 15 having an annular cross section and the height of the side peripheral surface 56 of the fluidizers 50a, 50b, 50c are reduced. The ratio b / c to b is preferably 0.75 to 0.83. By setting the ratio b / c between the width c of the medicine container 15 and the height b of the fluidizers 50a, 50b, and 50c to 0.75 to 0.83, there is an advantage that the effect of scraping the medicine is increased. It is done. Moreover, it is preferable that ratio b / a of the diameter a of the fluidizers 50a, 50b, and 50c and the height b of the side peripheral surface be 0.45 to 0.9. By setting the ratio b / a of the diameter a to the height b of the end faces 55 of the flowers 50a, 50b, and 50c to 0.45 to 0.9, the movement is stopped or it is difficult to move. The advantage that this can be effectively avoided is obtained.

  In the present embodiment, the outer shape of the columnar shape or the substantially cylindrical shape of the fluidizers 50a, 50b, 50c is, for example, a concave curved surface in which a side peripheral surface 56 sandwiched between a pair of end surfaces 55, 55 is recessed inward, Also included are convex curved surfaces that swell outward. In the present invention, the columnar shape having a low height of the fluidizer is not limited to a columnar shape or a substantially columnar shape, and includes a pair of end surfaces and a side peripheral surface between the end surfaces, for example, An elliptical column shape, a quadrangular column shape, a polygonal column shape or the like may be used. In this case, the diameter of the end face of the fluidizer means twice the cross-sectional secondary radius of the shape of the end face.

  According to this embodiment, the mixing attachment 10 further includes turbulent flow generation means 57 (see FIGS. 3A and 3B) that generates an irregular flow of water in the medicine storage chamber 15. As a result, the fluidizers 50a and 50b can be moved more randomly over the entire interior of the medicine storage chamber 15. That is, as shown in FIG. 5, for example, the turbulent flow generating means 57 includes two discharge wings 53 that are formed by opening a circumferential discharge port 52 on a notch surface 51 that faces in the circumferential direction and is shifted 180 degrees in the circumferential direction. And an axial outlet opening that is open upward and close to the outer peripheral surface of the discharge vane 53 at two locations that are 90 degrees apart from each notch surface 51 in the circumferential direction. 54 and 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 opening / closing slide member 25 in the axial direction X as shown in FIGS. 3 (a) and 3 (b) and FIGS. 6 (a) and 6 (b). When the drug injection port 23 and the slide injection port 24 are matched (see FIGS. 3A and 6A), the outer cylinder 17 rotates in the circumferential direction Y with respect to the inner cylinder 16. In the state in which the outer cylindrical body 17 is rotated and moved to open the raw water inflow path 21 and the outflow path 22 (see FIGS. 3B and 6B), 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. 6A), 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 cutout concave groove 28 (see FIG. 6B), 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 are matched, so that the drug injection is performed while excluding air from the air hole 36. 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, at least two kinds of fluidizers 50a, 50b, and 50c having different specific gravities that float inside by the action of the water flow from the inlet 37 to the outlet 39 are provided in the medicine storage chamber 15. The one or more types of fluid elements 50a, 50b, 50c have a low columnar shape including a pair of end surfaces 55, 55 and a side peripheral surface 56, and one end surface 55 Are stored in the medicine storage chamber 15 in a state of facing outward in the radial direction, and the fluidizers 50a, 50b, 50c are symmetrical with respect to the center of gravity and connect the peripheral edges of the pair of end faces 55, 55 diagonally. Since the length d is longer than the width c in the radial direction of the medicine storage chamber 15, it floats inside the medicine storage chamber 15 while maintaining a state in which one end face 55 is directed radially outward. These fluidizers 50a 50b and 50c collide with, for example, the wall of the drug storage chamber 15 by moving freely up and down, left and right without changing the contact surface with the inner wall surface of the outer cylinder 17 inside the drug storage chamber 15. However, by scraping off the drug in the vicinity of the inner wall surface of the outer cylindrical body 17 where the flow rate is particularly slow, it becomes possible to efficiently and slowly release the mixing drug while suppressing the remaining drug.

  In addition, according to the present embodiment, since two types of fluidizers 50 a, 50 b, 50 c having different specific gravities are accommodated in the medicine accommodating chamber 15, these fluidizers 50 a, 50 b, 50 c flow from the inlet 37. By the action of the flow of water toward the outlet 39, it is possible to move in a state of being distributed and held in a substantially equally divided region in the drug storage chamber 15, so that the drug storage chamber 15 is not biased. It is possible to efficiently and slowly release the drug over substantially the whole.

  By these, since the accumulation of drug residue and drug residue is effectively avoided, even when the mixing attachment 10 is used particularly for a long period of time, the mixing attachment 10 becomes dirty and the inside becomes difficult to see, It is possible to obtain a sufficient effect of the medicine stably without securing the appearance or waste of the medicine and sufficiently securing the desired desired sustained release time.

  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, 50b, and 50c so that the fluidizers 50a, 50b, and 50c can be further randomized and exposed, and the above functions can be exhibited more remarkably. Become.

  The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, it is not always necessary that at least two kinds of fluidizers having different specific gravities have a low columnar shape including a pair of end surfaces and a side peripheral surface between the end surfaces. A fluidizer having other shapes such as a shape, a bead shape, and a rectangular flat plate shape may be mixed. In addition, at least two kinds of fluidizers having different specific gravities are one kind of fluidizer having the same specific gravity by a columnar shape having a low height and having a pair of end surfaces and a side peripheral surface between the end surfaces, It may be a mixture of fluidizers having shapes other than different columnar shapes.

  In addition, the mixing attachment of the present invention is not limited to 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 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, in the present invention, in a state where the fluidizer is allowed to move without changing the contact surface inside the drug storage chamber, for example, as shown in FIG. A state where the contact surface faces radially outward is also included. 8A and 8B show a fluidizer that is symmetrical with respect to the center of gravity and that has a diagonal length connecting the peripheral edges of the pair of end faces longer than the radial width of the drug containing chamber. Such shapes are also included.

The attachment for mixing in Comparative Examples 1 to 5 in which the types and number of fluidizers shown in Table 1 are accommodated in the medicine storage chamber of the attachment having the same configuration as that of the attachment for mixing in the above embodiment is the shower device shown in FIG. In the same manner as in Examples 1 to 9, the agent remaining rate of the mixing drug accommodated in the drug accommodating chamber after sprinkling for a predetermined time was evaluated by the method for measuring the agent remaining described later. In addition, the rotation trouble determination method described later was used to determine the rotation trouble that does not move sufficiently due to the liquid crystal being caught or stopped in the medicine storage chamber. In addition, the capacity | capacitance of the chemical | medical agent storage chamber was 15 cc, the width c of the radial direction of the chemical | medical agent storage chamber was 6.3 mm in the comparative examples 1-3, and 5.6 mm was set to others. Table 1 shows the evaluation result of the remaining agent ratio and the determination result of the rotation trouble.

[Measurement method of drug residue rate]
Immediately after each of the drug storage chambers of the attachments of Examples 1 to 9 and Comparative Examples 1 to 5 was charged and stored with 12 g of a colored mixing drug having a viscosity of 13000 mPa · sec and a specific gravity of 0.93, the drug storage chamber was opened. A photograph is taken from the side, and the projected area of the inner wall of the storage chamber covered with the mixing agent is measured, and the area is defined as A. After supplying raw water to each attachment for attachment at a flow rate of 8 L / min from the shower water supply hose, the raw water inflow passage and the outflow passage are opened, and the raw water is passed through the medicine storage chamber for 15 seconds. The accommodation chamber is photographed from the side, and the projected area of the part covered with the undissolved mixing agent is measured, and the area is defined as B. B / A × 100 (%) is the residual ratio of the agent, less than 5% is “◎”, 5% to less than 10% is “◯”, 10% to less than 20% is “△”, and 20% or more is “×”. The remaining drug rate is evaluated.

[Judgment method for fluidizer rotation trouble]
A shower water supply hose immediately after 12 g of the mixing agent having a viscosity of 13000 mPa · sec and a specific gravity of 0.93 was charged and accommodated in each of the drug storage chambers of the attachments of Examples 1 to 9 and Comparative Examples 1 to 5 When supplying raw water at a flow rate of 8 L / min to each mixing attachment, opening the raw water inflow path and outflow path and allowing the raw water to pass through the drug storage chamber for 60 seconds, the fluidizer is within 10 seconds. In addition, it is confirmed whether or not rotation is started, and the number of rotation troubles caused by being caught or stopped without moving inside the medicine container is measured. When the fluidizer rotates within 10 seconds and the number of rotation troubles is 0 out of 10, “◎”, the fluidizer rotates within 10 seconds, and the number of rotation troubles is 1 to 2 out of 10 times. If the case is “◯”, the fluidizer rotates within 10 seconds and the number of rotation troubles is 3 or more out of 10 “△”. If the fluidizer does not rotate within 10 seconds, or the rotation trouble is 10 The case of 7 times or more is determined as “x”.

  From the evaluation result of the agent remaining rate shown in Table 1 and the determination result of the rotation trouble, the diagonal length connecting the peripheral edges of the pair of end faces is longer than the radial width of the drug containing chamber. According to the mixing attachments of Examples 1 to 9 according to the present invention in which the fluidizers housed in the medicine containing chamber are smaller than the mixing attachments of Comparative Examples 1 to 5, and the rotation trouble Therefore, within a desired time of, for example, about 10 to 60 seconds, the remaining amount of the agent can be remarkably reduced and the mixing agent can be efficiently mixed with the raw water. It turns out to be suitable to do.
