Referring to fig. 11 and 12, the present embodiment further provides a water tank, which includes a tank body 9 and any one of the above-mentioned detergent adding devices, the detergent adding device is installed in the tank body 9, an operation window 91 is opened on a side wall of the tank body 9 corresponding to the detergent adding device, the water tank is a hidden water tank (hidden in a wall), the operation window 91 is only exposed outwards, and the operation window 91 is disposed opposite to the liquid adding unit 2 so as to operate the liquid adding unit 2. The cistern in this embodiment is used to provide flushing water for a toilet, squat or urinal.

The use principle of the embodiment is briefly described as follows:

as shown in fig. 5 and fig. 6, in a normal state (i.e. during normal operation), the liquid adding unit 2 is located at the first position, the liquid adding channel 21 is in a closed state, so that the liquid inlet channel 15 is in a closed state, the liquid outlet channel 16, the leakage-proof channel 171 and the liquid feeding channel 4111 are all in an open state, the liquid storage chamber 14, the compartment 17 and the liquid feeding chamber 411 are in a relatively sealed state, detergent in the liquid storage chamber 14 flows into the compartment 17 through the liquid outlet channel 16 and flows into the liquid feeding chamber 411 through the leakage-proof channel 171, at this time, the liquid feeding channel 4111 is in an open state, but the detergent cannot flow out from the liquid feeding channel 4111 under the action of atmospheric pressure, so that the detergent cannot flow out from the liquid outlet channel 16 to the external atmosphere under the action of atmospheric pressure;

when the water tank stores water, the water level in the water tank rises, the floating drum 421 moves upwards under the action of buoyancy, the floating drum 421 compresses the elastic cavity wall 424 through the screw 422 and the lifting rod 423 in a linkage manner to enable the elastic cavity wall to generate elastic deformation, meanwhile, the push rod 425 is driven to move upwards to compress the volume of the liquid supply cavity 411, so that positive pressure is formed in the liquid supply cavity 411, the cleaning agent flows out from the liquid supply channel 4111 under the action of the positive pressure and flows into the cleaning agent temporary storage groove 71 for temporary storage through the liquid outlet pipeline 7, after the floating drum 421 stops moving upwards, the positive pressure in the liquid supply cavity 411 disappears, the cleaning agent stops flowing out, and quantitative liquid supply is; when the water tank drains, water in the water tank flows out from a water outlet channel of the drain valve base 8 and is mixed with a cleaning agent in the cleaning agent temporary storage groove 71 to form a cleaning solution for flushing a bed pan, meanwhile, the buoy 421 gradually descends along with the reduction of buoyancy, the elastic cavity wall 424 is driven to reset through the lifting rod 423, the ejector rod 425 is driven to move downwards, the liquid supply cavity 411 is restored to the initial volume, negative pressure is formed in the liquid supply cavity 411, outside air enters the liquid supply cavity 411 from the liquid supply channel 4111 under the action of the negative pressure and enters the liquid storage cavity 14 through the overflow pipeline 6, after the buoy 421 stops descending, the outside air does not enter the liquid supply cavity 411 any more, a new balance is achieved, and the water tank stores water again;

as shown in fig. 7, 8 and 9, when a cleaning agent needs to be added, the liquid adding unit 2 is pulled outwards through the operation window 91 to slide from the first position to the second position, the liquid adding channel 21 is opened and is communicated with the liquid storage cavity 14 through the liquid inlet channel 15, meanwhile, the liquid outlet channel 16 is automatically closed by the first valve core unit 3, the liquid storage cavity 14 is a cavity with a closed bottom and an open top, and at the moment, the cleaning agent is added into the liquid storage cavity 14 through the second liquid inlet 211 of the liquid adding channel 21; because the cleaning agent adding device is arranged in the box body 9 of the water tank, whether the liquid storage cavity 14 is filled with the cleaning agent is difficult to observe through the operation window 91, when the liquid storage cavity 14 is filled with the cleaning agent, redundant cleaning agent flows to the liquid feeding cavity 411 through the overflow channel, because the top of the liquid storage cavity 14 is opened at the moment, the top of the liquid storage cavity 14 is communicated with atmospheric pressure and the overflow pipeline 6, and the lower end of the overflow pipeline 6 is communicated with the liquid feeding cavity 411, so that the cleaning agent can flow out from the liquid feeding channel 4111 under the action of gravity and flows into a water seal at the bottom of a bedpan of the bedpan through the liquid outlet pipeline 7 and a water outlet channel of the drainage valve base 8, a user can conveniently judge whether the liquid storage cavity 14 is filled or not by observing the color change (if the color change is blue) of the water seal at the bottom of the bedpan and;

when the detergent is added, the liquid adding unit 2 is pushed inwards into the liquid inlet channel 15 to slide from the second position to the first position, the liquid adding channel 21 is closed, meanwhile, the liquid adding unit 2 drives the first valve core unit 3 to open the liquid outlet channel 16, the liquid storage cavity 14 is a cavity with an opening at the bottom and a closed top, and the normal state is recovered to the normal state shown in fig. 5 and 6.
