In addition, as shown in fig. 10 to 14, the toilet stool further includes: and a drug delivery mechanism 6. The drug delivery mechanism 6 includes: a medicine storage box 61, a medicine channel 62 and a channel opening and closing valve. The drug storage tank 61 is used for storing a drug, and the drug passage 62 communicates with the drug storage tank 61 and is connected to the water suction pipe 43. The passage opening/closing valve is provided in the water tank 1 for communicating the medicine passage 62 with the medicine storage tank 61 when the water level in the water tank 1 is lower than a preset water level.

Further, as shown in fig. 10-14, the medication channel 62 includes: a medicament inlet port 620 communicating with the medicament storage tank 61. The channel on-off valve includes: the suspension portion 631 is disposed in the water tank 1, and the valve cover 632 opens or closes the medicine inlet end 620. The connection portion 633 connects the suspending portion 631 and the valve cover 632, and extends from the water tank 1 into the medicine storage tank 61, for pulling the valve cover 632 away from the medicine inlet end 620 when the suspending portion 631 is lower than a preset water level.

In addition, as shown in fig. 10 to 14, the connection part 633 includes: a first lifting bar 6331 and a second lifting bar 6332. The first lifting rod 6331 is hinged to the outer wall of the drug storage box 61, and one end of the first lifting rod 6331 is connected to the suspension portion 631, and the first lifting rod 6331 rotates around the hinged position of the first lifting rod and the outer wall of the drug storage box 61.

The second lifting rod 6332 is used to drive the valve cap 632 to close or seal the drug inlet end 620 when the first lifting rod 6331 rotates.

Specifically, as shown in fig. 10-14, when the water level in the water tank 1 is higher than the preset water level, the suspending part 631 is lifted by the water flow, and the second lifting rod 6332 is pressed down to seal the medicine inlet end 620 against the valve cover 632. During the process of lowering the water level in the water tank 1, the buoyancy applied to the suspension portion 631 gradually decreases, so that the suspension portion 631 drives the first lifting bar 6331 to rotate clockwise around the hinge joint, and the second lifting bar 6332 is also driven, i.e. in an ascending trend. When the water level reaches the preset water level, the second lifting rod 6332 completely drives the valve cap 632 to be separated from the medicine inlet end 620, and the medicine in the medicine storage box 61 enters the medicine passage 62. In addition, when water is stored in the water tank 1 again, water flow contacts the suspension portion 631, after the suspension portion 631 receives buoyancy, the first lifting rod 6331 tends to rotate counterclockwise around the hinge, and the valve cover 632 and the second lifting rod 6332 are pressed down and driven by the first lifting rod 6331 to be pressed down until the valve cover 632 seals the medicine inlet end.

The limiting conduit 622 is connected to the medication inlet end 620 for the valve cap 632 to abut against the limiting conduit 622 when the valve cap 632 is moved to the limit position by the second lifting bar 6332. The limiting pipeline 622 is provided with a water inlet area communicated with the inside of the medicament storage box 61. Therefore, when the water level in the water tank 1 is particularly low, the valve cap 632 cannot be lifted and turned over by the second lifting rod 6332 without limit to be separated from the operation track, so that the valve cap 632 moves in a limited area, the water level in the water tank 1 rises, and when the floating part 631 floats, the second lifting rod 6332 can drive the valve cap 632 to continuously seal the medicament inlet end 620.

Further, as shown in fig. 10 to 14, the medicament delivery mechanism 6 further includes: the suspension ball 67 is movably arranged in the limiting pipe 622 and is positioned on one side of the valve cover 632, which faces the medicament inlet end 620, and is used for blocking the medicament inlet end 620. Thus, when the liquid medicine in the medicine storage tank 61 is discharged, the floating ball 67 falls down to seal the medicine inlet port 620. Avoid during the outside air sneaks into the water route of basin reason water supply mechanism, especially in this example to prevent air admission water pump, guaranteed the work efficiency of water pump.

In addition, as shown in fig. 10 to 14, the water suction duct 43 includes: a water suction port 430 extending into the water tank 1 for sucking water, wherein the caliber of the water suction port 430 of the water suction pipeline 43 is smaller than the inner diameter of the water suction pipeline 43; a damper valve 68 is provided in the main pipe 621. After the channel opening and closing valve opens the medicament inlet end 620, the rim water supply power part 42 works, the water suction pipeline 43 sucks water in the water tank 1, negative pressure is formed in the water suction pipeline 43 at the moment because the caliber of the water suction port 430 of the water suction pipeline 43 is smaller than the inner diameter of the water suction pipeline 43, and the spring part 681 in the damping valve 68 is sucked and pulled to open the damping valve 68, so that the medicament channel 62 is unblocked. When the channel opening/closing valve closes the medicine inlet port 620, the damper valve 68 further blocks the medicine channel 62, preventing the medicine from leaking from the medicine inlet port 620 into the water suction pipe 43. Meanwhile, when the water suction pipe 43 does not suck water in the water tank 1, this means that no medicine is required to enter the toilet bowl body 2, even if the water level in the water tank 1 is below the preset water level, the medicine inlet end 620 is opened, no negative pressure exists in the water suction pipe 43, the damping valve 68 is not opened, and at this time, the medicine will not enter the water suction pipe 43 to cause waste.

In addition, a partition 64 is further arranged in the medicament storage box 61, an isolation area 65 for placing medicaments is arranged in the partition 64, and a plurality of leakage holes 640 communicated with the isolation area 65 are formed in the partition 64. Thus, water flows into the isolation region 65 through the leak 640 to dissolve the drug, thereby preventing the drug residue from drifting and forming a standard material layout to avoid affecting other components.

Further, as shown in fig. 10 to 14, an opening for water in the water tank 1 to enter the medicine storage box 61 is formed in a side wall of the medicine storage box 61, and a door panel 69 for closing the opening is provided on the medicine storage box 61.

Specifically, as shown in fig. 14, the upper end of the door panel 69 is hinged to the side wall provided with the opening. The door 69 is configured to abut against the periphery of the opening when the opening is closed, and is inclined from top to bottom toward the inside of the drug storage box 61. There are two side shields 691 that stretch into the tank 1 at the open side, and the side that side shield 691 deviates from the opening is the inclined plane, and the distance of side shield 691 to the bottom of the opening is greater than the distance of side shield 691 to the top of the opening. The bottom of the opening is provided with a support plate 692 extending into the water tank 1, and the support plate 692 is connected to two side baffles 691, and abuts against the two side baffles 691 and the support plate 692 when the door plate 69 closes the opening. When the water in the water tank 1 reaches a certain amount, the door 69 can be opened, and the water flow enters the medicament storage tank 61 to dissolve the medicament. The door 69 is pushed to continue to close the opening when the water in the medicine storage tank 61 reaches a certain amount. Thereby allowing the agent storage case 61 to be automatically supplied with water.
