Referring to fig. 9 and 10, a detergent adding device of this embodiment is used for adding detergent into flush water of a toilet, and is installed in a tank body 10 of a toilet water tank, an operation window 101 is opened on a side wall of the tank body 10 corresponding to the detergent adding device, the water tank is a hidden water tank (hidden and installed in a wall body), the operation window 101 is only exposed outwards, and the operation window 101 is arranged opposite to a driving member 4 and a liquid adding nozzle 111 so as to operate the driving member 4 and the liquid adding nozzle 111. In this embodiment, the toilet is specifically a toilet, a squatting pan or a urinal.

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

as shown in fig. 4 and 5, in a normal state (i.e. in a normal operation), the driving member 4 is located at the second position, the liquid inlet channel 141 is in a closed state, the liquid outlet channel 142, the leakage-proof channel 151 and the liquid feeding channel 5111 are all in an open state, the liquid storage chamber 14, the compartment 15 and the liquid feeding chamber 511 are in a relatively sealed state, the detergent in the liquid storage chamber 14 flows into the compartment 15 through the liquid outlet channel 142 and flows into the liquid feeding chamber 511 through the leakage-proof channel 151, at this time, the liquid feeding channel 5111 is in an open state, but under an atmospheric pressure, the detergent cannot flow out from the liquid feeding channel 5111, so that the detergent cannot flow out from the liquid outlet channel 142 to the external atmosphere under an atmospheric pressure;

when the water tank stores water, the water level in the water tank rises, the float bowl 523 moves upwards under the action of buoyancy, the float bowl 523 is linked with the lifting rod 525 through the screw 524 to compress the elastic cavity wall 521 to enable the elastic cavity wall to generate elastic deformation, meanwhile, the ejector rod 522 is driven to move upwards to compress the volume of the liquid supply cavity 511, so that positive pressure is formed in the liquid supply cavity 511, the cleaning agent flows out from the liquid supply channel 5111 under the action of the positive pressure and flows into the cleaning agent temporary storage groove 81 for temporary storage through the liquid outlet pipeline 8, after the float bowl 523 stops moving upwards, the positive pressure in the liquid supply cavity 511 disappears, the cleaning agent stops flowing out, and quantitative liquid supply is completed; when the water tank drains, water in the water tank flows out from a water outlet channel of the drain valve base 9 and is mixed with a cleaning agent in the cleaning agent temporary storage groove 81 to form a cleaning solution for flushing a bed pan, meanwhile, the float 523 gradually descends along with the reduction of buoyancy, the elastic cavity wall 521 is driven to reset through the lifting rod 525, the ejector rod 522 is driven to move downwards, the liquid supply cavity 511 returns to the initial volume, negative pressure is formed in the liquid supply cavity 511, outside air enters the liquid supply cavity 511 from the liquid supply channel 5111 under the action of the negative pressure and enters the liquid storage cavity 14 through the overflow pipeline 7, after the float 523 stops descending, the outside air does not enter the liquid supply cavity 511 any more, new balance is achieved, and the water tank stores water again;

as shown in fig. 6 and 7, when a cleaning agent needs to be added, the driving member 4 is rotated from the second position to the first position through the operation window 101 of the box 10, the driving member 4 drives the first valve core 2 to open the liquid inlet channel 141, and simultaneously, the second valve core 3 automatically closes the liquid outlet channel 142, the liquid storage chamber 14 is a cavity with a closed bottom and an open top, and at this time, a bottle containing the cleaning agent is aligned with the liquid adding nozzle 111, so that the cleaning agent can be squeezed into the liquid storage chamber 14; because the cleaning agent adding device is arranged in the box body 10 of the water tank, whether the liquid storage cavity 14 is filled with the cleaning agent is difficult to observe through the operation window 101, when the liquid storage cavity 14 is filled with the cleaning agent, redundant cleaning agent flows to the liquid feeding cavity 511 through the overflow channel, at the moment, the top of the liquid storage cavity 14 is communicated with the atmospheric pressure and the overflow pipeline 7 due to the top opening of the liquid storage cavity 14, the lower end of the overflow pipeline 7 is communicated with the liquid feeding cavity 511, so that the cleaning agent can flow out from the liquid feeding channel 5111 under the action of gravity and flows into the water seal at the bottom of the bedpan through the liquid outlet pipeline 8 and the water outlet channel of the drain valve base 9, and 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.

In the embodiment, the box body is provided with a compression mechanism which is used for compressing the volume of the liquid storage cavity; when the compression mechanism compresses the volume of the liquid storage cavity, positive pressure is formed in the liquid storage cavity, and the cleaning agent flows out from the liquid outlet channel under the action of the positive pressure. Under the normal state, the liquid storage cavity is the initial volume, and when the compression mechanism resets, the liquid storage cavity resumes to the initial volume, forms the negative pressure in the liquid storage cavity, and outside air gets into the liquid storage cavity from the drain channel under the negative pressure effect. Of course, in other embodiments, the compressing mechanism may not be reset during operation, and the compressing mechanism compresses the fluid storage chamber to progressively compress the fluid storage chamber from the initial volume.

In this embodiment, the structures and principles of the remaining portions not described are consistent with the embodiment, and are not described herein again.
