Description

  The present invention relates to a chemical solution supply apparatus for supplying a chemical solution used for fragrance, toilet cleaning, and the like.

  Various chemical solution supply apparatuses for cleaning toilet bowls and obtaining an aroma effect have been proposed depending on the type of toilet bowl to be attached. For example, for a type having a water storage tank, a chemical liquid supply device has been proposed that is arranged in the hand washing section at the top of the tank, and this apparatus supplies chemical liquid into the water storage tank along with water supplied to the hand washing section. Is configured to do. On the other hand, toilet bowls that do not have a hand-washing section at the top of the tank or that do not have a water storage tank itself are also on the market. For this purpose, a chemical supply device that is directly attached to the toilet rim has been proposed.

As such a chemical solution supply apparatus, there is an apparatus as disclosed in Patent Document 1, for example. In this apparatus, the chemical liquid supplied on the plate from the chemical liquid container is exposed to running water to supply the chemical liquid to the inner wall surface of the toilet. As a result, the toilet bowl is washed, and the fragrance effect can be obtained by the fragrance contained in the chemical solution.
Special Table 2002-518611

  By the way, the chemical | medical solution container used with the said chemical | medical solution supply apparatus is provided with the thin film part in the discharge port from which a chemical | medical solution is discharged | emitted. In use, the communication pipe having the tip cut obliquely is pierced into the thin film portion, and the chemical solution is discharged from the discharge port into the communication pipe. At this time, since the open end portion of the communication pipe is cut obliquely, the thin film portion cannot be completely detached. Therefore, a rod-like protrusion is provided at the opening of the communication tube so that the thin film portion does not block the discharge port again, and the thin film portion supports the discharge port by this protrusion. .

  However, since at least a part of the thin film portion is still connected to the discharge port, even if the protrusion is provided, the discharge of the chemical solution may be hindered. In other words, even if the thin film portion does not completely block the discharge port, if it is in a position that covers the discharge port, the drug solution is prevented from being discharged from the discharge port, and the drug solution is appropriately supplied to the toilet. There is a problem that can not be. Such a problem is not only a device used for cleaning toilets, but also a problem common to all devices that perform fragrance, cleaning, etc. by discharging a chemical solution from a chemical solution container.

  The present invention has been made to solve the above-described problem, and an object of the present invention is to provide a chemical solution supply device that can reliably prevent the thin film portion of the chemical solution container from blocking the discharge port.

  A chemical solution supply apparatus according to the present invention is made to solve the above-described problem, and stores a chemical solution and has a chemical solution container having a discharge port for the chemical solution, and is connected to the discharge port. A chemical solution discharge mechanism that guides the chemical solution to the outside, and a support that supports the chemical solution container and the chemical solution discharge mechanism, and the chemical solution container has a thin film portion that closes the discharge port in an initial state before use. The chemical solution discharge mechanism includes a communication pipe inserted to break the thin film portion, and the communication pipe has at least one notch extending in the axial direction from the opening edge, When the communication pipe is inserted into the chemical liquid container, an opening edge of the communication pipe is configured to enter the chemical liquid container from a position where the thin film part is formed, so that the thin film part Leaves from the outlet That.

  According to this configuration, when the communication tube is inserted into the chemical solution container before use, the opening edge portion of the communication tube enters the chemical solution container from the position where the thin film portion is formed. Can be disengaged from. As a result, it is possible to reliably prevent the thin film portion from blocking the discharge port. At this time, there is a possibility that the chemical solution may remain outside the communication pipe inserted into the chemical solution container, but the communication pipe is formed with a notch from the opening edge, so the chemical solution outside the communication pipe is notched. It is discharged into the communication pipe through the section. Therefore, it is possible to prevent the chemical liquid from remaining. Even if the detached thin film portion blocks the opening of the communication pipe, the chemical solution can be discharged from the cutout portion.

  Further, the rear end portion of the cutout portion can be located near the position where the thin film portion is formed and at a position where the cutout portion enters the chemical solution container rather than the position where the thin film portion is formed. For example, when a gap is formed between the outer peripheral surface of the communication pipe and the discharge port of the chemical solution container outside the formation position of the thin film portion, the chemical solution may leak from the cutout portion. By comprising in this way, the leak of a chemical | medical solution can be prevented reliably. In addition, it is desirable that the rear end portion of the notch is disposed at a position as close as possible to the formation position of the thin film portion from the viewpoint of leaving as little chemical as possible in the container. It means a position where the residual chemical can be minimized.

  The shape of the open end portion of the communication tube is not particularly limited, but for example, the communication tube can be formed in a shape that is obliquely cut in the radial direction so that the tip is sharp. By doing so, it is easy to apply a force when the communication pipe is inserted into the thin film portion, and the thin film portion can be easily broken.

  The present invention can use, for example, a fragrance as a chemical solution and can be used as a fragrance supply device, or can be placed in a flush toilet and used for cleaning and aroma of a toilet.

  For example, the support body is configured to be arranged in a hand washing part at the upper part of the water storage tank in the flush toilet, and the chemical liquid discharged from the chemical liquid discharging mechanism is supplied to the water washing tank through the discharge hole together with the water supplied to the hand washing part. The chemical solution can be supplied into the inside.

  When used as a type to be disposed in the hand-washing section as described above, the support has a shape in which an inflow space into which water can flow is formed below the chemical liquid discharge mechanism, and a position adjacent to the inflow space. A storage part capable of storing a solid medicine is provided, and an opening that allows the storage part to communicate with the outside can be formed in the support. With such a configuration, not only the drug solution but also the drug eluted from the solid drug can be supplied to the toilet. For example, a chemical solution can be used as a cleaning / fragrance, and a solid drug can be used as a bleaching agent.

  According to this configuration, an inflow space into which water flows is formed below the chemical solution discharge mechanism, and a solid medicine container is formed adjacent to the inflow space. Therefore, the water going to the drainage hole flows smoothly into the drainage hole through the inflow space, so that the drainage near the drainage hole becomes better and the water overflows from the handwashing part, and the water accumulates in the handwashing part, and the solid drug is collected. It does not cause problems such as submergence and extreme drug loss or non-uniform dose reduction. In addition, since the water smoothly flows to the drainage hole below the chemical solution discharge mechanism, it is possible to prevent water from flowing back into the chemical solution discharge mechanism, and as a result, the chemical solution is diluted and discharged early. Can be prevented. In addition, since the solid medicine storage part is adjacent to the inflow space, the water flowing through the hand-washing part can be picked up from below, and water can be poured into the upper part of the container. Obtainable. The opening may be formed at any position as long as it allows water to flow into and discharge from the storage section. For example, the opening is formed below the apparatus as much as possible, such as below the chemical solution discharging mechanism. It is preferable to do.

  Moreover, the solid medicine arrange | positioned at this apparatus can make it have the external shape whose length of a 1st direction is longer than the length of the 2nd direction orthogonal to this in planar view. By doing so, the degree of freedom of arrangement of the solid drug in the support body is increased, and for example, it can be arranged at a position where it is more easily contacted with water. As the shape of such a solid medicine, for example, the plan view can be a rectangle, an ellipse, or the like.

  Furthermore, a guide member for guiding the chemical liquid discharged from the chemical liquid discharge mechanism to the outside of the support can be provided. At this time, it is preferable to extend the guide member to the inflow space. The inflow space is formed between the surface of the hand-washing part and the chemical solution discharge mechanism, and water easily flows in. Therefore, if a guide member is placed in this space, the water easily comes into contact with the chemical solution supplied to the guide member. It becomes easy. For this reason, a chemical | medical solution can be efficiently supplied to a water storage tank. Further, when the guide member is inserted into the discharge hole of the hand-washing portion, contact with water is further ensured, and the chemical solution can be efficiently supplied to the water storage tank.

  Moreover, not only the type arrange | positioned in a hand-washing part as mentioned above but it can also be used as a type attached to the rim of a toilet bowl. In this case, a chemical solution container, a drug discharge mechanism, and a suspension member for hanging the support on the toilet rim are further provided, and the support is configured to supply the drug solution discharged from the drug solution discharge mechanism with flowing water flowing in the toilet. It can comprise so that it can contact.

  Also in this type of apparatus, similarly to the first invention, it is possible to reliably prevent the thin film portion from blocking the discharge port and to prevent the chemical liquid from remaining in the container. .

  According to the chemical solution supply device of the present invention, it is possible to reliably prevent the thin film portion of the chemical solution container from blocking the discharge port. Moreover, since the notch part for chemical | medical solution discharge | emission is provided, the chemical | medical solution which remains in a container can be decreased as much as possible.

  The chemical liquid container 1 is formed in a transparent dome shape so that the remaining amount of chemical liquid such as an aromatic cleaning agent can be confirmed from the outside. The lower part of the container 1 becomes thinner as it goes downward, and has a discharge port at the lowermost part. And the cap 11 is attached to this discharge port. The cap 11 is composed of an annular main body 111 and a thin film portion 112 that closes the central hole. In use, the upper portion of the chemical solution discharge mechanism 3 is inserted into the thin film portion 112 and is broken. .

  Next, the chemical liquid discharging mechanism 3 will be described with reference to FIG. FIG. 5 is a plan view (a) and a cross-sectional view (b) of the upper member constituting the chemical solution discharging mechanism. As shown in FIG. 2, the chemical solution discharging mechanism 3 includes an upper member 31 disposed on the upper side and a lower member 32 disposed on the lower side, and the lower member 32 is integrated with the support 2. Is formed. The upper member 31 is formed in a substantially circular shape in plan view, and the lower part is open. On the other hand, the lower member 32 is formed in a substantially circular plane, and a wall member 321 protruding upward is formed around the lower member 32 so as to block the lower opening of the upper member 31. And the buffer space 33 which hold | maintains a chemical | medical solution is formed between both by combining the upper member 31 and the lower member 32. Hereinafter, the upper member 31 and the lower member 32 will be described in more detail.

  As shown in FIGS. 2 and 5, the upper member 31 is provided with a sharp cylindrical communication tube 311 at the center of the upper surface of the upper member 31. A semicircular raised portion 313 is provided on the right side of the communication pipe 311 via a groove 312, and four air circulation holes 314 are formed on the upper surface of the raised portion 313. On the other hand, on the left side of the communication pipe 311, that is, the side facing the second region 22, an arc-shaped holding part 315 that holds the solid medicine 4 is provided. The communication tube 311 is pierced into the cap 11 of the chemical solution container 1 described above and plays a role of breaking the thin film portion 112, and the main body portion 111 of the cap 11 is fitted in the groove 312 of the side portion. In addition, on the wall surface of the communication pipe 311, cutout portions 3111 extending downward from the upper end of the opening edge portion 3112 are formed at two locations, and the outflow of the chemical solution is promoted by the cutout portions 3111. This point will be described later. Further, a cylindrical fixed tube 316 extending toward the lower member 32 and a plurality of chemical solution communication holes 317 arranged in the vicinity thereof are formed on the inner bottom surface of the communication tube 311. These chemical solution communication holes 317 and the above-described air circulation holes 314 communicate with the buffer space 33.

  Next, the lower member 32 will be described with reference to FIG. FIG. 6 is a partial perspective view (a) and a plan view (b) of the lower member. As shown in FIG. 5, at the center of the lower member 32, a cylindrical guide tube 322 fitted to the fixed tube 316 of the upper member 31 and a circular fixed wall 323 provided so as to surround the periphery thereof. Is provided. The wall surface of the fixed tube 316 described above is fitted in the gap between the guide tube 322 and the fixed wall 323. The upper opening of the guide tube 322 has an obliquely cut shape, and a guide groove 324 extending in the vertical direction along the outer peripheral surface of the guide tube 322 is formed from the lower side of the opening. Here, as shown in FIG. 6, since the guide tube 322 is fitted inside the fixed tube 316, a chemical solution passage is formed by the inner wall surface of the fixed tube 316 and the guide groove 324. A space through which the chemical solution passes is also formed in the gap between the bottom surface of the gap between the guide tube 322 and the fixed wall 323 and the lower end portion of the fixed tube 316.

  More specifically, on the bottom surface of the gap, about 90 degrees on both sides of the guide groove 324 constitutes an extension path 325 of the chemical solution, and on the opposite side to the guide groove 324, a circle extending about 90 degrees is formed. A pair of arc-shaped outflow holes 326 are formed. Then, the chemical liquid that has passed through the extension path 325 is discharged from the outflow hole 326. The above-described guide member 5 is attached to the opening edge of the lower end of the outflow hole 326 so that the chemical liquid discharged from the outflow hole 326 is guided downward through the guide member 5. Here, the guide member 5 will be described in more detail. As shown in FIGS. 1 and 4, the guide member 5 includes three guide member pieces 51 extending radially at intervals of about 120 degrees in plan view. It extends to. Each guide member piece 51 is formed in a plate shape, and a plurality of grooves extending downward are formed on the surface thereof, and the chemical solution flows out to the discharge hole Y through the grooves. Moreover, the guide member 5 is arrange | positioned substantially planar vicinity of the chemical | medical solution supply apparatus by planar view.

  Next, the second region 22 where the solid medicine is arranged will be described. As shown in FIG. 3, the solid medicine 4 is arranged in the second region 22 so that the side surface along the major axis of the ellipse faces the first region 21 side. A plurality of openings 221 are formed on the bottom and side surfaces of the second region 22, and water flows in and out through the openings 221. A plurality of protrusions are formed on the bottom surface of the second region 22. More specifically, as shown in FIGS. 2 and 3, the three plate-like portions 222 that are in contact with the left and long-diameter end portions of the solid drug 4 and the plate-like portions 222 are arranged between these plate-like portions 222. Two protrusions 223 located above the portion 222 are provided. In addition, the right side of the solid medicine is held by the holding portion (first holding piece) 315 of the upper member 31 described above. As shown in FIG. 2, the holding portion 315 holds the upper end portion of the solid medicine 4, and the plate-like portion (second holding piece) 222 and the protruding portion (second holding piece) 223 are the lower end portion of the solid medicine 4. Is supposed to hold.

  Subsequently, the operation of the chemical solution supply apparatus configured as described above will be described. First, attachment of a chemical solution container will be described with reference to FIG. As described above, the cap 11 provided with the thin film portion 112 is attached to the discharge port of the chemical solution container 1, and the communication tube 311 of the upper member 31 is inserted into the thin film portion 112. At this time, as shown in FIG. 7B, when the communication pipe 311 is completely inserted, that is, when the main body 111 of the cap 11 comes into contact with the bottom surface of the groove 312 of the upper member 31, the communication pipe The lowest portion (the position of the line P) of the tip opening 311 obliquely cut out penetrates the thin film portion 112 (the position of the line Q) and is positioned above this. Thus, the thin film portion 112 is detached from the cap 11, and the chemical solution in the chemical solution container 1 flows into the communication pipe 311.

  Next, the flow of the chemical solution will be described. When the thin film portion 112 of the cap 11 is broken by the communication pipe 311, the chemical liquid flows out from the chemical liquid container 1 to the chemical liquid discharge mechanism 3, and a part thereof is in the buffer space 33 through the communication pipe 311 and the chemical liquid communication hole 317. Flow into. On the other hand, as shown in FIG. 6, the remaining chemical solution flows downward through the guide groove 324, and then flows out to the guide member 5 through the extension path 325 and the outflow hole 326. And this chemical | medical solution flows along the groove | channel of the guide member 5, and a part is hold | maintained on the guide member 5 while flowing below.

  Here, the function of the buffer space 33 described above will be described. The buffer space 33 functions as a buffer when a pressure change occurs in the chemical liquid container 1 due to a temperature change. For example, when the temperature rises and the chemical solution container 1 is warmed, the air in the container 1 expands and the inside of the container 1 becomes positive pressure. In this case, the chemical solution in the chemical solution container 1 is pushed out and discharged, but this chemical solution flows into the buffer space 33 through the chemical solution communication hole 317 in addition to the guide groove 324, so that the chemical solution is excessive from the guide groove 324. Is prevented from being leaked into the water. On the other hand, when the temperature of the chemical liquid container 1 decreases due to cooling by running water and the air in the chemical liquid container 1 contracts to a negative pressure, the chemical liquid is subjected to the air pressure through the air circulation holes 314. The buffer space 33 is sucked into the chemical liquid container 1 through the chemical liquid communication hole 317. As a result, it is possible to prevent the suction of water flowing into the support side into the chemical solution container 1 and the discharge of the chemical solution are restricted. In this way, the buffer space 33 is in the container 1 because most of the chemical liquid flows between the chemical liquid container 1 and the buffer space 33 even when a pressure change occurs in the chemical liquid container 1 due to a temperature change. It is possible to prevent the chemical solution from flowing out excessively or restricting outflow.

  After the apparatus is installed as described above, when water is flowed into the toilet bowl, the flowed water flows toward the discharge hole Y of the hand washing unit X. In the process, as shown in FIG. 1, the flowing water flows into the space Z below the first region 21 while sweeping the chemical solution on the guide member 5 and flows into the water storage tank from the discharge hole Y. A part of the flowing water flows into the opening 221 of the second region 22 and contacts the solid medicine 4. As a result, the solid medicine 4 is eluted, flows out from the opening 221 together with running water as a bleaching agent, and flows into the water storage tank through the discharge hole Y. Thereafter, by using the toilet bowl, the chemical solution and the bleaching agent flow out from the water storage tank to the toilet bowl, and washing and bleaching are performed.

  In the above configuration, a space Z into which water flows is formed below the drug solution discharge mechanism 3, and a storage portion for the solid drug 4 is formed so as to be adjacent to the space Z. Accordingly, since water flowing toward the drainage hole Y smoothly flows into the drainage hole Y through the space Z, water drainage near the drainage hole Y is improved, and water overflows from the handwashing part X or water in the handwashing part X. As a result, the solid drug 4 is submerged in water, and the problem that the drug is reduced rapidly or unevenly does not occur. In addition, since the water smoothly flows to the drainage hole Y below the chemical solution discharge mechanism 3, it is possible to prevent the water from flowing back into the chemical solution discharge mechanism 3, and as a result, the chemical solution is diluted early. It can be prevented from being discharged. Furthermore, since the storage part for the solid medicine 4 is adjacent to the space Z, the water flowing through the hand washing part Y can be picked up from the bottom and can be introduced into the container. Elution can be obtained. Note that when the guide member 5 is inserted into the drain hole Y, drainage near the drain hole Y deteriorates, but since the space Z is provided as described above, such drainage deterioration can be prevented.

  In addition, although there exists a possibility of flowing back into the chemical | medical solution container 1 through the chemical | medical solution supply mechanism 4 from the guide member 5, this is coped with as follows. That is, in the apparatus according to the present embodiment, the chemical liquid flows out onto the guide member 5 through the guide groove 324, the extension path 325, and the outflow hole 326. In particular, since the extension path 325 extends horizontally, the water that has flowed upward through the guide member 5 has to pass through the extension path 325 extending horizontally and then pass through the guide groove 324 extending further vertically. The chemical solution container 1 is not reached. Thus, in this apparatus, since the path | route extended horizontally is arrange | positioned in the path | route of the orthogonal | vertical direction from the guide member 5 to the chemical | medical solution container 1, entry of water can be prevented.

  As described above, according to the present embodiment, when the communication tube 311 is inserted into the chemical solution container 1, the opening edge of the communication tube 311 is located at a position where the thin film portion 112 is inserted into the chemical solution container 1. Therefore, the thin film portion 112 can be reliably detached from the cap 11. As a result, it is possible to reliably prevent the thin film portion 112 from blocking the discharge port. At this time, since the opening of the communication pipe 311 is located above the thin film portion 112, there is a possibility that the chemical liquid remains on the outer peripheral surface side of the communication pipe 311 and the discharge of the chemical liquid may be hindered. Since the notch 3111 is formed on the wall surface, the chemical liquid flows out to the chemical liquid discharge mechanism 3 side through the notch 3111 (see FIG. 7B). Therefore, even if the remaining amount of the chemical liquid is reduced, the chemical liquid can be discharged. Note that the rear end (the position of the line R), which is the lower end of the notch 3111, is configured to be positioned above the position (line Q) near the position where the thin film portion 112 was disposed. Thus, the chemical liquid is prevented from leaking from the gap between the cap 11 and the communication pipe 311.

(Second Embodiment)
Next, 2nd Embodiment of the chemical | medical solution supply apparatus which concerns on this invention is described, referring drawings. 8 is a perspective view of the chemical liquid supply apparatus according to the present embodiment, FIG. 9 is a cross-sectional view of FIG. 8, FIG. 10 is a cross-sectional view of FIG. 8 along the AA line of FIG. FIG. 12 is an exploded perspective view of FIG.

  This chemical solution supply device is used by being hung on the rim of a toilet bowl, and as shown in FIGS. 8 to 12, a chemical solution container 1 containing a chemical solution, and a support 2 for supporting this from below. And a suspension member 3 for hanging the device on the rim. In addition, a chemical liquid discharge mechanism 4 that supplies the chemical liquid flowing out from the chemical liquid container 1 to the bottom surface of the support body 2 is disposed inside the support body 2. Hereafter, each member mentioned above is demonstrated in detail.

  As shown in FIG. 12, the chemical solution container 1 is formed in a transparent dome shape and has a discharge port 11 on the lower surface. A cap 13 is attached to the discharge port 11. The cap 13 is composed of an annular main body 131 and a thin film portion 132 that closes the central hole. When used, the cap 13 breaks the thin film portion 132 to discharge the chemical solution.

  As shown in FIGS. 11 and 12, the support 2 includes a support plate (support member) 21 that forms a bottom surface, and a wall 22 that surrounds the support plate 21. The support plate 21 includes a base portion 211 having a substantially rectangular shape in plan view and a movable portion 212 that is swingably connected to one side thereof. The support plate 21 has three sides other than the side on which the movable portion 212 is provided. The wall body 22 described above is provided in a U-shape. Therefore, the support body 2 is formed in a cup shape in which one side wall is notched and opened, and a part of the base portion 211 and the movable portion 212 are configured to protrude from the open portion 23. As will be described later, running water flows into the support 2 from the open portion 23.

  Moreover, the support | pillar 24 extended upwards is attached to the center of the base 211, and the suspension member 3 is attached to the space between this support | pillar 24 and the cover member 411 mentioned later so that an up-down movement is possible. The hanging member 3 is formed in a band shape that is bent at two locations so as to be elastically deformable. In an initial state, the hanging member 3 is folded as shown in FIG. Further, since the hanging member 3 is configured to be movable up and down, the height of the chemical solution container 1 and the support 2 with respect to the rim can be adjusted so that the apparatus and the rim do not interfere with each other.

  Next, the support plate 21 will be described in more detail. As shown in FIG. 9, in the support plate 21 of the present embodiment, the base 211 and the movable portion 212 are integrally formed of resin or the like, and the base 211 is about 6 degrees toward the movable portion 212 side. Inclined downward. As a result, as will be described later, the discharged chemical liquid can easily flow to the rim side. The inclination angle α of the base 211 can be set to other than this, and can be set to, for example, 0 to 45 degrees, and preferably 3 to 30 degrees.

  A groove 213 is formed on the back surface of the support plate 21 along the boundary line between the base portion 211 and the movable portion 212. Therefore, since the boundary between the base 211 and the movable portion 212 is formed into a thin film shape by the groove 213, the movable portion 212 can swing with respect to the base 211. Further, since the groove 213 is formed on the back surface of the support plate 21, when the movable portion 212 is inclined downward, the opposing side wall surfaces in the groove 213 come into contact with each other, thereby restricting the downward inclination. (FIG. 9A). On the other hand, it is possible to tilt upward, and if a force is applied, the movable portion 212 can be swung upward. However, upward inclination is also regulated as follows. As shown in FIG. 8 and FIG. 9, a substantially rectangular side plate 214 is attached to both sides of the base portion 211, and an end surface extending vertically toward the movable portion 212 side of this side plate 214 is connected to the movable portion 212. Contact is possible. That is, when the movable portion 212 is inclined to an inclination angle β of 90 degrees or more, the end surface of the side plate 214 and the movable portion 212 are in contact with each other, and the movable portion 212 is not inclined further (FIG. 9).

  Next, the chemical liquid discharge mechanism 4 will be described. As shown in FIGS. 9-12, the chemical | medical solution discharge mechanism 4 is arrange | positioned between the chemical | medical solution container 1 and the support plate 21, the upper member 41 arrange | positioned at the upper side, and the lower member arrange | positioned at the lower side 42. The upper member 41 is formed in an elliptical cylindrical shape in plan view, and the lower part is open. On the other hand, the lower member 42 includes a plate-like portion 421 having an elliptical shape in plan view, and a low wall member 423 formed so as to extend in the vertical direction around the lower portion 42 so as to block the lower opening of the upper member 41. Placed in. And the buffer space 43 which hold | maintains a chemical | medical solution is formed between both by combining the upper member 41 and the lower member 42. Hereinafter, the upper member 41 and the lower member 42 will be described in more detail.

  As shown in FIGS. 9 and 12, a rail-like cover member 411 extending upward is attached to the side surface of the upper member 41. As described above, the cover member 411 is in contact with the support column 24 and suspended. A space for accommodating the hanging member 3 is formed. The upper member 41 is provided with a sharp cylindrical communication pipe 412 with a sharply cut end at the center of the upper surface, and a total of four air circulation holes 413 at the end of the upper surface. . The communication pipe 412 is pierced by the cap 13 of the chemical solution container 1 described above and plays a role of breaking the thin film portion 132. A cutout 4121 extending in the axial direction from the opening edge 4122 is formed on the wall surface. An annular groove 417 is formed on the periphery of the communication pipe 412, and the main body 131 of the cap 13 is fitted in the groove 413. On the other hand, as shown in FIG. 9, a cylindrical fixed pipe 414 extending toward the lower member 42 and a plurality of chemical liquid communication holes 415 arranged in the vicinity thereof are formed on the inner bottom surface of the communication pipe 412. . The chemical solution communication holes 415 and the air circulation holes 413 described above communicate with the buffer space 43.

Next, the lower member 42 will be described with reference to FIGS. 13 is a perspective view (a), a plan view (b), a front view (c), and a bottom view (d) as seen from the lower surface of the lower member, and FIG. 14 is a partial perspective view (a) of the lower member. Its plan view (b). First, as shown in FIG. 12, at the center of the lower member 42, a cylindrical guide tube 424 fitted to the fixed tube 414 of the upper member 41, and a circular fixed wall 425 provided so as to surround the periphery thereof. And are provided. The above-described fixed tube 414 is fitted into the gap between the guide tube 424 and the fixed wall 425. The upper opening of the guide tube 424 has an obliquely cut shape, and a guide groove 426 extending in the vertical direction along the outer peripheral surface of the guide tube 424 is formed from the lower side of the opening. Here, as shown in FIGS. 13 and 14, since the guide tube 424 is fitted inside the fixed tube 414, a chemical solution passage (guide channel) is formed by the inner wall surface of the fixed tube 414 and the guide groove 426. Is done. Further, a space through which the chemical solution passes, that is, an extension path 427 is also formed in the gap between the bottom surface of the gap between the guide tube 424 and the fixed wall 425 and the lower end portion of the fixed tube 414. More specifically, on the bottom surface of the gap, about 90 degrees on each side of the guide groove 426 constitutes an extension path 427 for the chemical solution, and on the opposite side to the guide groove 426, a half of about 180 degrees is formed. A circular outflow hole 428 is formed. And the chemical | medical solution which passed the extension path 427 flows out from the outflow hole 428 to the support plate 21 side. Incidentally, the volume of each extension passage 427 is preferably 0.05 to 0.3 mm ^3, and more preferably a 0.07~0.15mm ^3. Further, the cross-sectional area of the extension passage 427 is preferably 0.02 to 0.1 mm ^2, further preferably 0.03~0.05mm ^2.

  As shown in FIG. 13, a pair of leg portions 429 are attached to both ends of the lower end of the wall member 423 in the lower member 42, and the leg portions 429 provide a space between the lower surface of the lower member 42 and the support plate 21. A space is formed. As will be described later, this space serves as a path for chemicals and running water. Further, on the lower surface of the lower member 42, a protruding piece 431 that connects both ends of the above-described outflow hole 428 and a pair of protrusions 432 that extend from both ends of the protruding piece 431 are formed. Each protrusion 432 extends obliquely toward the movable portion 212 so as to be separated from each other, and as shown in FIG. 13C, the protrusion height from the lower surface of the lower member 42 increases toward the tip. Is getting bigger. That is, as shown in FIG. 9, the gap between the protrusions 432 and the support plate 21 becomes smaller toward the tip, and is in contact with the support plate 21 at the tip.

  Next, a method of using the chemical solution supply apparatus configured as described above will be described with reference to FIGS. FIG. 15 is a cross-sectional view showing the attachment of the chemical solution container, and FIG. 16 is a side view showing the attached state of the chemical solution supply device. First, the chemical solution container 1 is disposed on the upper member 41. Thereby, the communication pipe 412 is pierced into the cap 13 of the chemical solution container 1 and the chemical solution container 1 is fixed. At this time, as shown in FIG. 15B, when the communication pipe 412 is completely inserted, that is, when the tip of the main body 131 of the cap 13 comes into contact with the bottom surface of the groove 417 of the upper member 41, the communication The lowest portion (the position of the line P) of the tip opening cut obliquely of the tube 412 penetrates the thin film portion 132 (the position of the line Q) and is positioned above this. With such a positional relationship, the thin film portion 132 is surely detached from the cap 13, so that the discharge port of the container 1 can be reliably prevented from being blocked. As described above, since the opening of the communication pipe 412 is located above the thin film portion 132, there is a possibility that the discharge of the chemical solution may be hindered. However, the notch 4121 extends from the opening edge 4122 to the wall surface of the communication pipe 412. Since it is formed, the chemical liquid flows out to the chemical liquid discharge mechanism 4 side through the notch 4121. Therefore, even if the remaining amount of the chemical liquid is reduced, the chemical liquid can be discharged. Note that the lower end (the position of the line R) of the notch portion 4121 is configured to be positioned above the thin film portion 132, thereby preventing the chemical liquid from leaking from the gap between the cap 13 and the communication pipe 412. is doing.

  Subsequently, when the device is attached to the rim of the toilet bowl, the hanging member 3 is pushed out from the state of FIG. And as shown to Fig.15 (a), it arrange | positions so that the rim | limb R may be pinched | interposed. At this time, the movable portion 212 abuts on the inner wall surface of the toilet bowl, but can be swung with respect to the base portion 211, and therefore tilts according to the distance between the base portion 211 and the toilet inner wall surface S. That is, as shown in FIG. 15A, when the distance between the base 211 and the toilet inner wall surface S is small, the movable portion 212 is greatly inclined while being pressed against the toilet inner wall surface S, and the clearance between the toilet inner wall surface S and Fill. On the other hand, when the distance is large, the inclination angle β is small as shown in FIG. 15B, but in any case, the gap between the base 211 and the toilet inner wall surface S is filled. As a result, since the chemical liquid that has flowed out to the base portion 211 can be efficiently swept away and flowed to the toilet bowl, an excellent cleaning effect can be obtained regardless of the shape of the toilet bowl.

  Subsequently, the flow of the chemical solution will be described. When the thin film portion 132 of the cap 13 is broken by the communication pipe 412, the chemical solution flows out from the chemical solution container 1 to the chemical solution discharge mechanism 4, and a part thereof is in the buffer space 43 via the communication tube 412 and the chemical solution communication hole 415. Flow into. On the other hand, as shown in FIGS. 13 and 14, the remaining chemical liquid flows downward through the guide groove 426 and then flows out to the lower surface side of the lower member 42 through the extension path 427 and the outflow hole 428. And this chemical | medical solution moves to the movable part 212 side along the protrusion 431 and the protrusion part 432, and moves to the support plate 21 in the contact part of the support plate 21 and the protrusion part 432. FIG. Since the base portion 211 of the support plate 21 is slightly inclined downward, the chemical solution flows downward and is accumulated at the boundary portion with the movable portion 212. At this time, the fragrance | flavor contained in a chemical | medical solution volatilizes and the aroma effect is acquired. The function and operation of the buffer space 43 are the same as those in the first embodiment.

  After the apparatus is installed as described above, when water is flowed into the toilet, the flowed water travels along the toilet inner wall surface S from the inside of the rim R as shown in FIG. Guided to the 211 side (arrow X). Then, the chemical solution stored at the boundary portion between the base portion 211 and the movable portion 212 is swept away while flowing out from the water flow hole 25 or bounced back against the wall body 22 in the device, and from the open portion 23 to the outside of the device. To flow. Thus, the chemical solution is supplied to the toilet inner wall surface S together with running water, and the toilet bowl is cleaned.

  As described above, according to this embodiment, the same effect as that of the first embodiment can be obtained. That is, it is possible to reliably prevent the thin film portion from blocking the discharge port and to prevent the chemical solution from remaining in the container.
