Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-6As shown, a foot-operated delayed flush valve includes a flush tank 1. A large-diameter flush pipe 2 and a small-diameter flush pipe 3 are fixedly inserted into the bottom of the flush tank 1. A partition plate 4 is fixedly installed on the inner wall of the flush tank 1. When in use, water is injected into the cavity of the flush tank 1 below the partition plate 4. A U-shaped slide 5 is fixedly installed on the top of the partition plate 4. An elastic sealing valve assembly 6 is installed on the U-shaped slide 5. The elastic sealing valve assembly 6 is divided into two groups, with one end of each group inserted into the large-diameter flush pipe 2 and the small-diameter flush pipe 3, respectively, to seal the large-diameter flush pipe 2 and the small-diameter flush pipe 3. Under the action of the elastic sealing valve assembly 6, the large-diameter flush pipe 2 and the small-diameter flush pipe 3 are sealed, achieving temporary storage of water in the flush tank 1. A lifting slider 7 is slidably engaged in the U-shaped slide 5. One end of the lifting slider 7... A serpentine connecting rod 8 is fixedly installed and slidably engaged in a limiting groove opened at the top of the flush tank 1. A push plate 9 and a foot pedal 10 are installed at one end of the serpentine connecting rod 8. Controlling the push plate 9 allows the serpentine connecting rod 8 to slide in the limiting groove, so that the lifting slider 7 corresponds to the elastic sealing valve assembly 6 on the large-diameter flush pipe 2 and the small-diameter flush pipe 3 respectively. When the foot pedal 10 is pressed, the lifting slider 7 can drive the two sets of elastic sealing valve assemblies 6 respectively, so that the large-diameter flush pipe 2 and the small-diameter flush pipe 3 can be opened respectively. The usage method is more flexible and more economical. The foot pedal 10 is fixedly connected to the serpentine connecting rod 8 through the plug-in positioning assembly 11, so as to facilitate the disassembly and assembly of the foot pedal 10, improve the convenience of replacing the foot pedal 10, and avoid damage to the foot pedal 10 affecting the overall use.

[0023] The elastically clamping and sealing valve assembly 6 includes a U-shaped fixing seat 601, which is fixedly installed on the top of a U-shaped slide 5. A vertical limiting rod 602 is slidably inserted into the U-shaped fixing seat 601. A lifting drive block 603 is fixedly installed at one end of the vertical limiting rod 602. The lifting drive block 603 is elastically connected to the inner wall of the U-shaped fixing seat 601 through a return spring 604, and the lifting drive block 603 is movably embedded in the U-shaped slide 5. A circular stop block 605 is fixedly installed at the other end of the vertical limiting rod 602. An L-shaped valve stem 606 is fixedly installed on the side wall of the lifting drive block 603. A circular sealing valve is fixedly installed at one end of the L-shaped valve stem 606. When block 607 controls the lifting slider 7 to move upward, it drives the lifting drive block 603 to move upward in the U-shaped fixed seat 601 through the vertical limit rod 602. Through the L-shaped valve rod 606, it drives the circular closing valve block 607 to move upward, so that the large-diameter flushing pipe 2 or the small-diameter flushing pipe 3 can be opened to achieve flushing. After flushing, under the action of the return spring 604, the lifting drive block 603 is reset, so that the circular closing valve block 607 is inserted into the large-diameter flushing pipe 2 and the small-diameter flushing pipe 3 to achieve the closure of the large-diameter flushing pipe 2 and the small-diameter flushing pipe 3, so as to temporarily store water in the flushing tank 1.

[0024] The insertion positioning assembly 11 includes a connecting strip 1101. One end of the serpentine connecting rod 8 is fixedly mounted on the connecting strip 1101. A limiting installation groove is formed on the connecting strip 1101. A bidirectional lead screw 1103 is rotatably mounted on the inner wall of one end of the limiting installation groove via a rotating joint 1102. One end of the bidirectional lead screw 1103 rotatably passes through the connecting strip 1101 and is fixedly mounted with a turning handle 1104. A threaded slider 1105 is mounted on the bidirectional lead screw 1103. The threaded slider 1105 is slidably engaged in the limiting installation groove.

The pin block 1107, the first L-shaped pin block 1106, and the second L-shaped pin block 1107 are inserted into the connecting slot at one end of the foot pedal 10. In use, the control handle 1104 is turned so that the double-acting screw 1103 rotates in the limiting mounting groove through the rotating joint 1102, driving the two threaded sliders 1105 to slide in opposite directions in the limiting mounting groove, causing the first L-shaped pin block 1106 and the second L-shaped pin block 1107 to move to the sides or move inward, so that the first L-shaped pin block 1106 and the second L-shaped pin block 1107 can be inserted into the connecting slot, and at the same time, it is convenient to separate the first L-shaped pin block 1106 and the second L-shaped pin block 1107 from the connecting slot, so as to facilitate the disassembly and replacement of the foot pedal 10.
