And a surrounding wall 42 depending from the periphery of the upper surface portion 40, and the lower portion is open. By fitting the inner side wall 41 to the inside of the outer side wall 34 of the support 3, the cover member 4 is mounted so as to cover the bottom surface portion 30. At this time, the surrounding wall 42 is separated from the outer peripheral surface of the outer side wall 34. The upper surface portion 40 includes a lower portion 40a having a circular shape in a plan view and a upper portion 40b around the lower portion 40a which is higher than the lower portion 40a. A cylindrical connecting member 43 connected to the discharge port 21 of the chemical solution container 2 is provided at the central position of the lower portion 40 a.

  The connection member 43 is provided on the upper surface of the lower portion 40 a of the cover member 4. As shown in FIG. 23, the connecting member 43 is composed of a distal end 43A and a proximal end 43B larger in diameter than the distal end 43A. The upper end of the tip portion 43A is cut off obliquely, and the upper opening is inclined. As shown in FIG. 24, when the connection member 43 is connected to the discharge port 21 of the chemical solution container 2 and both are fitted, the base end 43 B of the connection member 43 is fitted in the main body 27 of the cap 22. Then, while being in contact with the inner peripheral surface of the inner side wall 27A, the engaging projection 27D of the main body 27 is engaged with the distal end 43A of the connecting member 43 and is in contact with the outer peripheral surface of the distal end 43A.

  Referring back to FIGS. 18 to 22, a cylindrical discharge member 44 having a diameter smaller than that of the connection member 43 is concentrically provided on the lower surface of the lower portion 40 a of the cover member 4. The connection member 43 and the discharge member 44 communicate with each other through the flow hole 45, and the insides of the connection member 43 and the discharge member 44 constitute a chemical solution passage for passing the chemical solution from the chemical solution container 2 to the guide member 5 described later. ing. A plurality of (three in the illustrated example) communication holes 61 are formed around the discharge member 44 in the connection member 43. The communication hole 61 constitutes an adjustment mechanism 6 described later.

  Referring back to FIGS. 10 to 15, a circular bottom hole 35 is formed in the central portion of the region surrounded by the outer side wall 34 of the bottom portion 30 of the support 3. The discharge member 44 of the cover member 4 can be fitted in the bottom hole 35. A plate-like guide member 5 is provided on the lower surface of the bottom surface 30 of the support 3 so as to cross the bottom hole 35. The guide member 5 is for guiding the drug solution discharged from the drug solution container 2 through the connection member 43 and the discharge member 44 to a position in contact with the intermittently flowing liquid outside the support 3, and the guide member A fitting protrusion 50 that can be fitted in the discharge member 44 is provided on the upper surface of the fifth member 5. As shown in FIG. 16, a longitudinal groove 51 extending from the upper end to the lower end is formed on the outer surface of the fitting projection 50, and between the inner circumferential surface of the discharge member 44 and the longitudinal groove 51. A drug solution outlet is formed. The cross-sectional shape of the longitudinal groove 51 can be various shapes such as a semicircular shape, a square shape such as a triangle or a quadrangle, and the like. In addition, it is desirable that the cross-sectional dimension be such that the drug solution can be drawn out along the lead-out path by capillary action. An annular wall 36 to which the discharge member 44 can be fitted is provided around the bottom hole 35 in order to securely hold the fitting state of the discharge member 44 and the fitting projection 50.

  The upper surface of the guide member 5 is in contact with the lower end portion of the discharge member 44. As shown in FIG. 17, a large number of narrow grooves 52 extending in the vertical direction are formed on the front and back plate surfaces of the guide member 5. The guide member 5 is located between the two long legs 32 and is inserted into the water outlet of the water supply receiver together with the long legs 32. However, the guide member 5 is formed slightly shorter than the long leg portion 32, and only the lower end portion thereof can be inserted into the drainage port. A cylindrical shielding wall 37 is provided between the guide member 5 and the long leg 32. The shielding wall 37 is formed shorter than the guiding member 5, and the long leg 32 positions the support 3 at the drainage port, and the guiding member 5 contacts the water flowing down to the drainage port. The above drug solution is washed away with water and flows into the water storage tank. On the other hand, the shielding wall 37 regulates the backflow of flowing water from the outlet to the inside of the support 3.

  The support 3 is assembled by fitting the inner side wall 41 of the cover member 4 to the inside of the outer side wall 34 of the bottom portion 30. Thereby, as shown in FIG. 3 and FIG. 4, the buffer chamber 60 is formed between the bottom surface portion 30 and the cover member 4 in the support 3. The buffer chamber 60 is separated from the discharge member 44, and has a space in which the drug solution can be stored.

  The buffer chamber 60 constitutes the adjustment mechanism 6 for adjusting the amount of the chemical solution discharged from the chemical solution container 2, and the adjustment mechanism 6 includes the buffer chamber 60, the communication hole 61 described above, and the air in the buffer chamber 60. Are formed by the air flow holes 62 for introducing the The communication hole 61 can introduce a part of the drug solution discharged from the drug solution container 2 to the connection member 43 into the buffer chamber 60.

  The air flow holes 62 are provided in the side wall (consisting of the outer side wall 34 and the inner side wall 41) of the buffer chamber 60 in this embodiment. That is, the upper end portion of the outer side wall 34 of the support 3 is notched in a concave shape, whereby the through hole 63 (shown in FIGS. 12 and 15) is formed in the outer side wall 34. The wall 41 is formed with a slit 64 (shown in FIGS. 19 and 21) extending in the vertical direction from the upper end to the lower end. The slit 64 is formed at a position corresponding to the through hole 63 of the outer side wall 34 of the support 3, and the cover member 4 is attached to the support 3 to match the through hole 63 with the slit 64. , And the air flow holes 62 are formed.

  In the present embodiment, the air flow holes 62 are provided to face the end positions of the side walls (the outer wall 34 and the inner wall 41) of the buffer chamber 60 having a substantially elliptical shape in plan view in the longitudinal direction. The arrangement of the air flow holes 62 is not necessarily limited to this, and can be provided at any position on the side wall of the buffer chamber 60. Further, in the present embodiment, the air flow hole 62 is provided at the upper end portion of the side wall of the buffer chamber 60, but may be provided at a lower position than the upper end portion. However, if it is arranged too low, when water supplied to the water supply tray intrudes into the interior of the support 3, the water may enter the buffer chamber 60 through the air flow holes 62, which is not preferable. . Further, in the present embodiment, the air flow holes 62 are formed by providing the vertically elongated slits 64 in the inner side wall 41, but the inner side wall 41 is also provided with through holes in the same manner as the outer side wall 34. The air flow holes 62 may be formed by matching the two. Further, in the present embodiment, the air flow holes 62 are directed in the horizontal direction, but may be formed to be downward (obliquely downward) in the horizontal direction.

  In addition, the air flow holes 62 do not necessarily have to be provided in the side wall 62 of the buffer chamber 60, and may be provided in the upper wall of the buffer chamber 60 (upper surface portion 40 of the cover member 4).

  The adjustment mechanism 6 described above acts on the temperature change of the chemical solution container 2 as follows. For example, when the temperature rises and the drug solution container 2 is warmed, the air in the drug solution container 2 expands and the inside of the drug solution container 2 becomes positive pressure. In this case, the drug solution in the drug solution container 2 is pushed out and discharged from the discharge port 21, but the discharged drug solution flows from the discharge member 44 into the lead-out path and also flows into the buffer chamber 60 through the communication hole 61. Therefore, the drug solution is prevented from flowing out excessively to the lead-out path.

  On the other hand, when the temperature of the drug solution container 2 is lowered by cooling with flowing water or the like, the air in the drug solution container 2 contracts and the inside of the drug solution container 2 becomes negative pressure. In this case, the chemical solution in the buffer chamber 60, which is at atmospheric pressure or room pressure, is sucked into the chemical solution container 2 through the communication hole 61 by the action of the air flow hole 62. Therefore, the return of the water or the diluted drug solution on the guide member 5 to the drug solution container 2 side through the discharge member 44 is suppressed. In addition, the negative pressure in the chemical solution container 2 prevents the discharge of the chemical solution from being restricted. As described above, even when a pressure change occurs in the drug solution container 2 due to a temperature change by the adjusting mechanism 6, the flow of the drug solution occurs between the drug solution container 2 and the buffer chamber 60. Can prevent excessive spillage or limited spillage. The volume of the buffer chamber 60 (the volume between the lower end surface of the communication hole 61 and the lower surface of the air flow hole 62) is the volume of the chemical solution container 2 (the volume to the upper surface of the discharge port 21 in FIG. 5) It is preferable to have the following relationship. That is, when the volume of the drug solution container 2 is 75 ml, the volume of the buffer chamber 60 is preferably about 2.7 ml, and when the volume of the drug solution container 2 is 100 ml, the volume of the buffer chamber 60 is about 3.6 ml When the volume of the drug solution container 2 is 150 ml, the volume of the buffer chamber 60 is preferably about 5.4 ml. By setting the capacities of the drug solution container 2 and the buffer chamber 60 as described above, for example, the drug solution may leak from the fitting portion between the outer wall 34 of the support 3 and the inner wall 41 of the cover member 4. Thus, the function of the buffer chamber 60 is sufficiently exerted.

  Referring back to FIGS. 10 to 15, the side surface portion 31 of the support 3 is formed with an opening 38 for diffusing the aroma component of the chemical solution to the outside. In addition, an opening 39 is formed at the outer side position of the outer side wall 34 of the bottom portion 30 for discharging the water to the outside when the water supplied to the water supply tray intrudes into the inside of the support 3. .

  The support 3 is provided with at least one pressing portion 7 which can move at least partially inward by pressing. On the other hand, as shown in FIG. 4, FIG. 5 and FIG. 7, the liquid medicine container 2 is moved upward as the pushing part 7 moves inward with the pushing part 7 in contact. A trigger 8 is provided to trigger the That is, the inducing unit 8 contacts the pressing unit 7 by the inward movement of the pressing unit 7, and after the contacting with the pressing unit 7, the inducing unit 8 presses the pressing unit 7 from the pressing unit 7 along with the inward movement of the pressing unit 7. By receiving pressure, the drug solution container 2 is configured to be pushed upward and moved. When the drug solution container 2 is in a fitted state with the support 3, the upward movement of the drug solution container 2 acts to automatically release the fit with the support 3. Therefore, in the drug solution supply device 1 of the present embodiment, when the drug solution container 2 is removed from the support 3, the drug solution container 2 is fitted with the support 3 by simply pressing the pressing portion 7 inward. The drug solution container 2 can be easily removed from the support 3 because it moves upward.

  In the present embodiment, the plate-like pressing portion 7 is a support by providing a pair of notches 70 extending from the upper end toward the lower side (bottom surface portion 30) in the side surface 31 of the support 3 at intervals. It is provided integrally with 3. The plate-like pressing portion 7 can be tilted in the inward / outward direction of the support 3 with respect to the side surface portion 31 with the base end portion 71 (the connecting portion with the side surface portion 31 located at the tip of the notch 70) as an axis The upper end portion 72 of the pressing portion 7 moves inward with the tilting of the pressing portion 7. In the present embodiment, since the upper end portion 72 of the pressing portion 7 is located almost directly above the base end portion 71, the upper end portion 72 of the pressing portion 7 is arc-shaped by inward tilting of the pressing portion 7. Move as you draw diagonally downward.

  Further, in the present embodiment, the pressing portion 7 is formed in a rectangular shape by forming the pair of notches 70 in parallel in the side surface portion 31, and the two corners of the upper end portion 72 of the pressing portion 7 Is chamfered. However, the outer shape of the pressing portion 7 is not limited to the rectangular shape, and can be formed in various shapes. For example, the external shape of the pressing portion 7 is formed in a trapezoidal shape, a reverse trapezoidal shape, a triangular shape, or the like by providing the pair of notches 70 in the V shape, the reverse C shape or the reverse V shape in the side surface portion 31 It is also good. In addition, it is preferable that the upper end part 72 of the press part 7 is formed in the external shape which has a width | variety like rectangular shape, trapezoid shape, inverted trapezoidal shape etc. FIG. As a result, the pressing portion 7 moves on the sliding surface 80 in a state where the upper end portion 72 contacts the sliding surface 80 of the chemical solution container 2 as described in detail later. It can be moved straight along the extending direction. As a result, since the drug solution container 2 can be moved straight upward with respect to the support 3, the fitting between the drug solution container 2 and the support 3 can be favorably removed.

  Further, the same plate-like pressing portion 7 can be integrally provided on the support 3 by providing not the slit-like notch 70 having a predetermined width but a linear notch in the side surface portion 31. Further, even if the pair of notches 70 (or notches) are not provided from the upper end of the side surface portion 31, for example, the notches (or notches) such as U-shaped, U-shaped or V-shaped are convex upward Thus, by providing the side surface portion 31, the plate-like pressing portion 7 capable of tilting in the inner and outer directions of the support 3 with respect to the side surface portion 31 can be integrally provided on the support 3.

  The position of the pressing portion 7 provided on the support 3 is not particularly limited, but the front edge 3 C and / or the rear edge 3 D, which are portions extending in the longitudinal direction (first direction) of the support 3 Is preferably provided. When the drug solution container 2 is removed from the support 3, it is necessary to hold the support 3 with one hand and press the pressing portion 7 with a finger, but in the longitudinal direction (first direction) of the support 3. When the pressing portion 7 is provided in the extended portion, the support 3 is gripped by hand and the pressing operation of the pressing portion 7 can be easily performed with a finger.

  Further, at least one pressing portion 7 may be provided on the support 3, but it is preferable that the pressing portion 7 be provided on the support 3 such that the pair of pressing portions 7 face each other. The pressing unit 7 is configured such that the inward movement by pressing pushes the drug solution container 2 upward through the inducing unit 8, but by pinching the drug solution container 2 by the pair of pressing units 7, the drug solution container 2 can be pushed straight up. Therefore, the fitting between the drug solution container 2 and the support 3 can be removed well. In the present embodiment, the pair of pressing portions 7 are respectively disposed at central positions in the longitudinal direction of the front edge 3C and the rear edge 3D of the side surface portion 31 of the support 3.

  On the other hand, as shown in FIGS. 4, 5 and 7, in the present embodiment, the inducing portion 8 is provided on the upper surface of the drug solution storage portion 20, and the upper end portion of the pressing portion 7 is tilted by tilting of the pressing portion 7. A sliding surface 80 slides on the sliding surface 72. In addition, "sliding" means moving in contact and sliding. On the upper surface of the drug solution storage unit 20, a raised portion 23 is formed which is gently raised in the shape of a mountain from the vicinity of the peripheral edge toward the vicinity of the center, and a sliding surface 80 is formed as a part of the raised portion 23 is cut out. It is done. Further, the discharge port 21 is provided at a substantially central position of the protruding portion 23.

  The inducing portion 8 (sliding surface 80) is provided in the drug solution container 2 so as to correspond to the pressing unit 7 when the drug solution container 2 is attached to the support 3. In this embodiment, the front edge 2C and the rear edge 2D, which are portions extending in the longitudinal direction (first direction) of the drug solution container 2, are respectively provided, and the front edge 2C and the rear edge 2D At the central position in the length direction, the discharge port 21 is disposed opposite to the other.

  Further, in the present embodiment, the concave portion 24 formed by cutting out a part of the protruding portion 23 in a concave shape is respectively provided at the center position in the longitudinal direction of the front edge 2C and the rear edge 2D of the drug solution container 2 It is provided. The edge on the front edge 2C or the rear edge 2D side (front side) of the recess 24 is open, and the pressing portion 7 moving inward from the opening can be received in the recess 24. In addition, the concave portion 24 includes a bottom wall surface extending in the movement direction of the pressing portion 7, and in the present embodiment, the bottom wall surface constitutes the sliding surface 80. The side wall surface 25 of the recess 24 is continuously provided at the left and right end edges of the sliding surface 80, and the back wall surface 26 of the recess 24 is at the end edge of the discharge port 21 side (rear side) of the sliding surface 80. It is arranged in a row. The lateral width of the sliding surface 80 (the bottom wall surface of the recess 26) is set to be slightly larger than the lateral width of the pressing portion 7 so that the pressing portion 7 can be received. Since the sliding surface 80 is provided in the recess 24, the upper end portion 72 of the pressing unit 7 slides on the sliding surface 80 while being guided by the both side wall surfaces 25 of the recess 24. Therefore, since the pressing portion 7 can be moved straight along the direction in which the sliding surface 80 extends, the drug solution container 2 can be moved straight up with respect to the support 3. As a result, the fitting between the drug solution container 2 and the support 3 can be removed well.

  In the present embodiment, the sliding surface 80 inclines higher (lower in FIG. 4 showing the chemical solution container 2 in use) toward the inner side (the discharge port 21 side), that is, the upper surface of the chemical solution storage portion 20 It is formed in the inclined surface where the height from becomes high. As described above, in the present embodiment, the upper end portion 72 of the pressing portion 7 moves obliquely downward so as to draw a circular arc inward. Therefore, by making the sliding surface 80 an inclined surface inclined in the same direction as the moving direction of the upper end portion 72 of the pressing portion 7, the upper end portion 72 of the pressing portion 7 contacts the sliding surface 80 while sliding Continue moving along the 80s. Thereby, a pressing force acts on the sliding surface 80 from the pressing portion 7, and the pressing force acting on the sliding surface 80 is such that the chemical solution container 2 is upward by the sliding surface 80 being inclined obliquely downward. The upward movement of the drug solution container 2 can be induced.

  The sliding surface 80 may be a flat surface inclined linearly in a cross sectional view, or may be a curved surface inclined in a curved shape in a cross sectional view, but the sliding surface 80 is configured by a curved surface. Is preferred. As described above, since the upper end portion 72 of the pressing portion 7 moves in a circular arc, if the sliding surface 80 is a curved surface, it follows the moving direction of the upper end portion 72 of the pressing portion 7. The upper end portion 72 can slide smoothly.

  The sliding surface 80 is preferably formed by continuously providing a plurality of inclined surfaces having different degrees of inclination. For example, the sliding surface 80 is moved inward (toward the discharge port 21). It is preferable for the following reason if it is formed so as to make the inclination degree steep.

  That is, when the sliding surface 80 is formed so that the degree of inclination becomes steeper toward the inner side (the discharge port 21 side), the upper end portion 72 of the pressing portion 7 slides by the inward movement of the pressing portion 7 In the initial stage of sliding on the surface 80, since the degree of inclination of the sliding surface 80 is gentle, the chemical solution container 2 is moved upward via the sliding surface 80 accompanying the inward movement of the pressing portion 7. The amount of movement is small. On the other hand, since the degree of inclination of the sliding surface 80 becomes steeper as the upper end portion 72 of the pressing portion 7 slides on the sliding surface 80, the sliding surface 80 accompanying the inward movement of the pressing portion 7 The moving amount of moving the drug solution container 2 upward is increased.

  Here, in the state where the drug solution container 2 is mounted on the support 3, the connection member 43 is fitted in the discharge port 21, whereby the drug solution container 2 is fixed to the support 3 and becomes difficult to remove. ing. Therefore, when the user tries to remove the drug solution container 2 from the support 3, the user may press the pressing portion 7 of the support 3 strongly (momentarily). In this case, if the degree of inclination of the sliding surface 80 is sharp at the initial stage when the upper end portion 72 of the pressing portion 7 slides on the sliding surface 80, the sliding occurs along with the inward movement of the pressing portion 7. The moving amount for moving the drug solution container 2 upward through the surface 80 is increased. As a result, when the drug solution container 2 suddenly moves up largely, the fitting with the support 3 is released, and there is a possibility that the drug solution container 2 is vigorously detached from the support 3 against the user's intention.

  On the other hand, at the initial stage where the upper end portion 72 of the pressing portion 7 slides on the sliding surface 80, the user removes the drug solution container 2 from the support 3 if the degree of inclination of the sliding surface 80 is gentle. In doing so, even if the pressing portion 7 of the support 3 is pressed strongly (momentarily), the drug solution container 2 is moved upward via the sliding surface 80 accompanying the inward movement of the pressing portion 7 Because the amount of movement is small, the drug solution container 2 does not move so much upward. Therefore, the fitting between the drug solution container 2 and the support 3 is suddenly released, and it is possible to prevent the drug solution container 2 from being vigorously detached from the support 3. Then, as the upper end portion 72 of the pressing portion 7 slides on the sliding surface 80, the degree of inclination of the sliding surface 80 becomes sharp, so the sliding surface 80 accompanying the inward movement of the pressing portion 7 The moving amount of moving the drug solution container 2 upward is increased. As a result, the drug solution container 2 is largely moved upward and the fitting with the support 3 is released, and the drug solution container 2 can be easily removed from the support 3.

  The degree of inclination refers to the amount of vertical displacement (the distance from the horizontal surface) with respect to changes in the horizontal direction, and if the inclined surface is a flat surface, it refers to the inclination angle of the flat surface to the horizontal surface. In the case of a curved surface, it indicates the bending of the curved surface, that is, the radius of curvature. In the case where the sliding surface 80 is formed so as to have a steeper degree of inclination as it goes inward, in the case of a combination of flat surfaces, a flat surface having a steep inclination angle as it goes inward. Arrange in order. Moreover, in the case of the combination of curved surfaces, the curved surfaces with a small radius of curvature are arranged in order as it goes inward. In the case of a combination of a flat surface and a curved surface, in the case where the flat surface and the curved surface are arranged in order, the inclination angle of the flat surface is made equal to or less than the inclination angle of the tangent at the connecting portion with the flat surface of the curved surface. When arranging in order of a curved surface and a flat surface, the inclination angle of a flat surface is made more than the inclination angle of the tangent in a connection part with the flat surface of a curved surface.

  In the sliding surface 80, when the upper end portion 72 of the pressing portion 7 slides to the end of the sliding surface 80 (in the present embodiment, the boundary with the back wall surface 26), the chemical container 2 and the support 3 It is preferable that the degree of inclination be set so that the drug solution container 2 moves upward until the fitting (in the present embodiment, the fitting between the discharge port 21 and the connection member 43) is released. Thereby, when the upper end portion 72 of the pressing portion 7 abuts against the back wall surface 26 of the concave portion 24 at the end of the sliding surface 80, the fitting between the drug solution container 2 and the support 3 is released and the drug solution container 2 is a support It can confirm that it is removable from 3. In addition, the chemical solution container 2 is further moved upward because the upper end portion 72 of the pressing portion 7 abuts against the back wall surface 26 of the recess 24 and does not slide inward even if the pressing portion 7 is pressed any more. Is regulated. Accordingly, it is possible to prevent the chemical solution container 2 from being vigorously detached from the support 3 against the user's will.

  Here, in the state where the discharge port 21 and the connection member 43 are fitted as in the present embodiment, the state where the fitting between the drug solution container 2 and the support 3 is released is referred to FIG. 24. The inner side wall 27A of the cap 22 moves upward along with the upward movement of the drug solution container 2, and is positioned above at least the proximal end 43B of the connection member 43 to contact the outer peripheral surface of the proximal end 43B. It says the state where it doesn't touch. At this time, the engagement projection 27D of the inner side wall portion 27 may or may not be in contact with the outer peripheral surface of the distal end portion 43A of the connection member 43. A portion of the projection 27D may be in contact with the outer peripheral surface of the tip 43A. If the fitting between at least the proximal end 43B of the connection member 43 and the inner side wall 27A of the cap 22 is disengaged and both are not in contact with each other, the drug container 2 is simply grasped and lifted. The drug solution container 2 can be removed from 3. Therefore, the fitting state between the drug solution container 2 and the support 3 is the fitting state as in the present embodiment (a contact between the base end 43B of the connection member 43 and the inner side wall 27A of the cap 22, a connection member In the case where it is different from the fitting state due to the contact at the upper and lower two places of the contact of the tip portion 43A of 43 and the engaging projection 27D of the cap 22), the fitting between the drug solution container 2 and the support 3 is released Is a state in which the drug solution container 2 can be removed from the support 3 with almost no force by merely grasping and lifting the drug solution container 2.

  The sliding surface 80 is a fit between the drug solution container 2 and the support 3 before the upper end portion 72 of the pressing portion 7 reaches the end of the sliding surface 80 (the boundary with the back wall surface 26 in this embodiment). (In the present embodiment, the degree of inclination may be set so that the drug solution container 2 moves upward until the fitting of the discharge port 21 and the connection member 43 is released. In this case, the sliding surface 80 is set to such a length that the upper end portion 72 of the pressing portion 7 can slide even after the fitting between the chemical solution container 2 and the support 3 is released. In this case, when the upper end portion 72 of the pressing portion 7 abuts against the back wall surface 26 of the concave portion 24 at the end of the sliding surface 80, the chemical solution container 2 slightly floats from the support 3, so any force is required. The drug solution container 2 can be removed from the support 3 without. In this case, it is preferable to set the degree of inclination of the sliding surface 80 so that the drug solution container 2 does not come off the support 3 vigorously.

  According to the chemical solution supply device 1 configured as described above, the chemical solution container 2 is fixed to the support 3 by fitting the connection member 43 of the support 3 to the discharge port 21 of the chemical solution container 2 through the cap 22. Then, the guide member 5 and the long leg 32 of the support 3 are inserted into the drainage port of the water supply tray at the upper portion of the water storage tank of the flush toilet, whereby the chemical solution in the chemical solution container 2 The chemical solution on the guide member 5 is drained to the guide member 5, and the chemical solution on the guide member 5 is washed away by the water supplied to the water supply tray at the time of flushing, thereby flowing from the drainage port to the water storage tank.

  When all the drug solution in the drug solution container 2 is discharged with use, the empty drug solution container 2 can be replaced with a new drug solution container 2 to enable continuous use. In this case, it is necessary to remove the drug solution container 2 from the support 3. However, in the drug solution supply device 1 configured as described above, the support 3 and the drug solution container 2 are provided with the pressing portion 7 and the inducing portion 8 (sliding surface 80). Since the inward movement of the pressing unit 7 is configured to move the drug solution container 2 upward via the inducing unit 8, simply pressing the pressing unit 7 inward simply The drug solution container 2 moves upward and the fitting with the support 3 is automatically released. Therefore, the drug solution container 2 can be easily removed from the support 3, and there is no need to strongly pull the drug solution container 2 away from the support 3 when removing the drug solution container 2 from the support 3. There is no risk of the remaining chemical solution splattering from the discharge port 21, and there is no risk of adhering to the clothes or the like of the user. In addition, when the drug solution container 2 is removed from the support 3, while the drug solution supply device 1 is installed on the water supply tray, the pressing portion 7 of the support 3 is pressed with one hand, and the drug solution with the other hand. The drug solution container 2 can be removed from the support 3 by grasping and lifting the container 2. Therefore, since the hand does not touch the guide member 5 of the support 3, when the drug solution container 2 is removed from the support 3, there is no possibility that the drug solution adheres to the hand and becomes dirty with the drug solution, and the user feels uncomfortable. There is no fear.

  Further, since the pair of pressing part 7 and the inducing part 8 (sliding surface 80) are provided opposite to each other on the drug solution container 2 and the support 3, the drug solution container 2 is sandwiched by the pair of pressing parts 7 Since the drug solution container 2 can be pushed up straight and moved through the inducing portion 8, the fit between the drug solution container 2 and the support 3 can be removed well.

  Further, the front side edge portions 2C and 3C and the rear side edge which are portions in which the pair of pressing portions 7 and the inducing portions 8 (sliding surface 80) extend in the longitudinal direction (first direction) of the drug solution container 2 and the support 3 Since it is provided in the portions 2D and 3D, when the drug solution container 2 is removed from the support 3, the support 3 can be easily grasped with one hand, and thus the pressing operation of the pressing portion 7 can be facilitated.

  Further, since the inducing portion 8 (sliding surface 80) is provided in the recess 26 and the upper end portion 72 of the pressing portion 7 slides on the sliding surface 80 while being guided by the both side wall surfaces 25 of the recess 26 The portion 7 can be moved straight in the direction in which the sliding surface 80 extends. Therefore, since the chemical | medical solution container 2 can be moved straight upward with respect to the support body 3, the fitting with the chemical | medical solution container 2 and the support body 3 can be removed favorably.

  As mentioned above, although one embodiment of the present invention was explained in full detail, a concrete mode of the present invention is not limited to an above-mentioned embodiment. For example, in the above embodiment, the sliding surface 80 constituting the inducing portion 8 is inclined to be higher (lower in FIG. 4 showing the chemical solution container 2 in use) toward the inside (the outlet 21 side). However, it may be formed in a flat horizontal surface extending horizontally without being inclined toward the inside (the outlet 21 side). In this case, as shown in FIG. 25, the pressing portion 7 is provided on the support 3 in a state of being obliquely inclined so that the upper end portion 72 is positioned on the outer side larger than the base end portion 71. . Thus, the upper end portion 72 of the pressing portion 7 moves obliquely upward in a circular arc by tilting the pressing portion 7 inward. Therefore, when the upper end portion 72 of the pressing portion 7 slides on the sliding surface 80 along with the inward movement of the pressing portion 7 if the sliding surface 80 is a horizontal surface, the sliding surface 80 is the pressing portion 7. Is pushed upward by Thereby, since the drug solution container 2 moves upward, the sliding surface 80 can induce the upward movement of the drug solution container 2 as the pressing portion 7 moves inward. In the case where the pressing portion 7 is provided in an inclined state so as to fall to the outside on the support 3, the sliding surface 80 is not limited to the horizontal surface, and decreases toward the inside (the discharge port 21 side). It may be formed in the inclined surface which inclines (it is high in FIG. 4 showing the chemical | medical solution container 2 at the time of use). Also in this case, when the upper end portion 72 of the pressing portion 7 slides on the sliding surface 80 along with the inward movement of the pressing portion 7, the sliding surface 80 is pushed up by the pressing portion 7. Therefore, since the chemical solution container 2 moves upward, the sliding surface 80 can induce the upward movement of the chemical solution container 2 along with the inward movement of the pressing portion 7.

  Further, in the above embodiment, the recessed portion 24 is provided in the raised portion 23 of the upper surface of the drug solution container 2 (the drug solution storage portion 20), and the sliding surface 80 constituting the inducing portion 8 is configured by the bottom wall surface of the recessed portion 24. However, as shown in FIG. 26 to FIG. 29, it is notched by notching a part of the protrusion 23 obliquely, for example, without providing the recess 24 in the protrusion 23 of the drug solution container 2 (drug solution storage unit 20). The surface of the raised portion 23 may be a sliding surface 80. In this embodiment, the sliding surface 80 extends to the vicinity of the outlet 21. As the sliding surface 80, when the upper end portion 72 of the pressing portion 7 slides to the root position of the discharge port 21 which is the end of the sliding surface 80 as in the above embodiment, the chemical solution container 2 and the support 3 The degree of inclination may be set so that the drug solution container 2 moves upward until the fitting with the connector (the fitting between the discharge port 21 and the connecting member 43) is released, or the upper end portion 72 of the pressing portion 7 Before the liquid crystal container 2 and the support 3 are disengaged (the connection between the discharge port 21 and the connection member 43) before the liquid reaches the root position of the discharge port 21 which is the end of the sliding surface 80 The degree of inclination may be set such that 2 moves upward. In the former case, the sliding surface 80 is set to such a length that the upper end portion 72 of the pressing unit 7 can slide until the liquid chemical container 2 and the support 3 are disengaged. In the latter case, the sliding surface 80 is set to such a length that the upper end portion 72 of the pressing portion 7 can slide even after the fitting between the drug solution container 2 and the support 3 is released. In addition, the position, the number, etc. provided in the chemical | medical solution container 2 of the sliding face 80 in this embodiment can be made to be the same as that of the said embodiment. Further, the other configurations of the drug solution container 2 shown in FIGS. 26 to 29 are the same as the configurations of the drug solution container 2 of the above-described embodiment shown in FIGS. A detailed explanation is omitted by doing.

  Further, in the above embodiment, the sliding surface 80 constituting the inducing portion 8 spreads in a planar manner, such as the bottom wall surface of the recess 24 or the surface of the notched portion of the protruding portion 23. As shown in FIG. 32, for example, the top surface of the chemical solution container 2 (chemical solution storage unit 20) extends along the moving direction of the pressing unit 7 (in FIG. 32, the discharge port from the front edge 2C and the rear edge 2D) At least one rib 81 extending toward 21 may be provided, and the surface of the rib 81 may be a sliding surface 80. In this embodiment, the height of the rib 81 is set such that the upper end portion 72 of the pressing portion 7 contacts the sliding surface 80 of the surface of the rib 81 as the pressing portion 7 moves inward. As the ribs 81, one having a wide width may be provided on the upper surface of the drug solution container 2 (the drug solution storage portion 20), or a plurality of ribs having a narrow width may be provided in parallel at intervals. It may be In addition, the rib 81 has a surface (sliding surface 80) inclined higher or lower toward the inside (the discharge port 21 side) according to the moving direction of the upper end portion 72 when the pressing portion 7 tilts inward. It may be formed in the inclined surface which does not incline, and may be formed in the flat horizontal surface which extends horizontally without inclining toward the inner side (the discharge port 21 side). Further, in FIG. 30 to FIG. 32, although the rib 81 is provided in the recess 24 provided at the center position in the longitudinal direction of the front edge 2C and the rear edge 2D of the chemical liquid container 2, Is not necessary.

  Moreover, although the induction | guidance | derivation part 8 is comprised by the sliding face 80 in the said embodiment, as shown to FIGS. 33-35, the induction | guidance | derivation part 8 can be comprised from the protrusion 82. As shown in FIG. The projection 82 is located in the moving direction of the pressing unit 7 on the upper surface of the drug solution container 2 (the drug solution storage unit 20), and the upper end portion 72 of the pressing unit 7 is protruded as the pressing unit 7 moves inward. The installation location and height are set so as to hit 82. In this embodiment, when the pressing portion 7 moves further inward with the upper end portion 72 of the pressing portion 7 abutted against and in contact with the protrusion 82, the pressing portion 7 rides over the protrusion 82. Therefore, a pressing force upward from the pressing portion 7 acts on the protrusion 82. Thereby, since the drug solution container 2 is pushed upward, the protrusion 82 can induce the upward movement of the drug solution container 2 as the pressing portion 7 moves inward. As the protrusion 82, one having a large outer diameter may be provided on the upper surface of the drug solution container 2 (the drug solution storage portion 20), or a plurality of small protrusions may be provided in parallel at intervals. It may be Further, in FIG. 33 to FIG. 35, the projection 82 is provided in the recess 24 provided at the center position in the longitudinal direction of the front edge 2C and the rear edge 2D of the chemical liquid container 2. Is not necessary.

  Further, in the above embodiment, the pressing portion 7 is integrally provided on the side surface portion 31 by providing the notch 70 (or a notch) on the side surface portion 31 of the support 3, but as shown in FIG. Even if the height of the side portion 31 at the position where the pressing portion 7 is provided is lowered without providing the notch 70 or the like in the side portion 31, the plate-like pressing portion 7 is provided on the upper end portion of the side portion 31. Good. Further, the pressing portion 7 may be a movable body provided so as to be slidable in and out with respect to the side surface portion 31 of the support 3, and the tip of the pressing portion 7 is slid by inward sliding movement of the pressing portion 7. The part is in contact with, for example, the sliding surface 80 in the inclined state, and is configured to push the chemical solution container 2 upward through the sliding surface 80 as it moves further inward in the state in contact with the sliding surface 80 It may be done. In addition, at least a portion moves inward by pressing to come in contact with the inducing portion 8 and moves the chemical solution container 2 upward via the inducing portion 8 as it moves further inward in contact with the inducing portion 8 The pressing portion 7 can be configured in various ways as long as it is configured to push up.

  Further, in the above embodiment, the chemical solution storage portion 20 and the discharge port 21 of the chemical solution container 2 are one, and the chemical solution corresponding to which the connection member 43, the buffer chamber 60 and the like are provided one by one. Although the supply apparatus 1 has been described, according to the present invention, as shown in FIGS. 40 to 42, the chemical solution storage portion 20 and the discharge port 21 of the chemical solution container 2, the connecting member 43 of the support 3 and the buffer chamber 60 etc. The present invention can also be applied to a chemical liquid supply apparatus provided with two (or three or more).
