Unpowered automatic flushing module for flush valve having integrated flushing opening/closing portion

An unpowered automatic flushing module for a flush valve having an integrated flushing opening/closing portion configured integrally with a detection switch (100) module, the unpowered automatic flushing module comprising:

• the detection switch (100) configured to guide descending motion of a toilet seat (10) under a weight load of a toilet user, and allow the toilet seat (10) to ascend when the pressurized weight load is released as the toilet user leaves the toilet seat (10);
• a toilet paper time control and flushing adjustment part (200) configured to discharge air inside a guide rib (210) while a urine flushing adjustment (240) and a flushing adjustment part (220) in conjunction with the descending motion of the toilet seat (10) ascends, control time to dispose of toilet paper with feces and the flushing of the feces while suctioning the air from outside through a toilet paper time adjustment hole (231″) and a feces flushing adjustment hole (227″) with a restoring force of a restoration spring (224) when the toilet user leaves the toilet seat after defecation, and control the urine toilet paper time and urine flushing while rapidly suctioning the air from the outside through the toilet paper time adjustment hole (231″), the feces flushing adjustment hole (227″), and a urine flushing adjustment hole (242″) when the toilet user leaves the toilet seat after urination;
• a feces and urine distinction part (300) configured to adjust an amount of internal air discharged to the outside while a guide rod (330) moves into a distinction guide rib (310) in conjunction with the descending motion of the toilet seat (10), determine as urination when a urine flushing adjustment hole (243) is opened because a feces and urine determination member (340) fails to press the urine flushing determination pin (241), and determine as defecation when the feces and urine determination member (340) closes the urine flushing adjustment hole (243) by pressing the urine flushing determination pin (241);
• and
• the flushing opening/dosing portion (400) configured such that when the toilet seat (10) is descending, a first opening/closing valve (421) and a second opening/dosing valve (422) ascend at the same time by the detection switch (100), so as to dose a water supply hole (411) by the first opening/closing valve (421) and open a water drain hole (412) by the second opening/closing valve (422), thereby preparing to drain water from a pressure chamber into a toilet body and allowing a rotation release member (431) to be inserted to support an opening/closing pin (421a) of the first opening/dosing valve (421) and a water drain valve body (422a) of the second opening/dosing valve (422), the flushing opening/closing portion (400) being configured such that when the detection switch (100) is restored due to leaving of the toilet user from the toilet seat, the rotation release member (431) is pressed while the opening/closing pin (421a) of the first opening/dosing valve (421) and the water drain valve body (422a) of the second opening/closing valve (422) descend, and the rotation release member (431) is rotated while a pressurization release piece (226) of the toilet paper time control and flushing adjustment part (200) descends, thereby controlling toilet paper time until the opening/closing pin (421a) of the first opening/closing valve (421) is released, the flushing opening/closing portion (400) being configured such that when the opening/closing pin (421a) of the first opening/closing valve (421) being pressurized is released by rotating the rotation release member (431) while the pressurization release piece (226) of the toilet paper time control and flushing adjustment part (200) descends, since the water supply hole (411) is opened regardless of high water pressure and simultaneously the water drain valve body (422a) of the second opening/closing valve (422) opens the water drain hole (412), thereby flushing a toilet while draining the water stored in the pressure chamber of a flush valve (20) into the toilet body, and the flushing opening/dosing portion (400) being configured such that when a pressurizing force of the water drain valve body (422a) of the second opening/dosing valve (422) is released by rotating the rotation release member (431) while the pressurization release piece (226) of the toilet paper time control and flushing adjustment part (200) is descending, the water stored in the pressure chamber of the flush valve (20) is prevented from being drained, thereby stopping the toilet flushing.
