DETAILED DESCRIPTION

[0022] See also Figure 1-Figure 7 A pop-up flush valve comprises a valve body 1, the top of the valve body 1 is connected with a liquid inlet pipe, the bottom of the valve body 1 is connected with a drain pipe, and the surface of the valve body 1 is provided with a sealing mechanism 2 and a receiving mechanism 3;

[0023] The sealing mechanism 2 enables the valve body 1 to be sealed and opened, and the storage mechanism 3 enables the pedal 306 to be stored when not in use.

[0024] The storage mechanism 3 includes a storage shell 301, which is fixed to the surface of the valve body 1. A rotating shaft 302 is fixed to the inner wall of the storage shell 301. A trigger plate 303 is rotatably connected to the surface of the rotating shaft 302. An L-shaped plate 304 is fixed to the surface of the trigger plate 303. A first spring 305 and a guide rod 307 are fixed to the surface of the L-shaped plate 304. A pedal 306 is fixed to the surface of the first spring 305. The guide rod 307 penetrates the pedal 306. A linkage shell 308 is fixed to the rear surface of the pedal 306. A mounting shell 309 is fixed to the rear surface of the storage shell 301. A combination block 310 is fixed to the inner wall of the housing 309, a fixed shaft 311 is fixed to the inner wall of the combination block 310, a rotating plate 312 is rotatably connected to the surface of the fixed shaft 311, a first connecting plate 313 and a second connecting plate 315 are hingedly connected to the surface of the rotating plate 312, a trigger rod 314 is fixed to the surface of the first connecting plate 313, the trigger rod 314 is slidably connected to the inner wall of the combination block 310, a wedge block 316 is fixed to the surface of the second connecting plate 315, a second spring 317 is fixed to the surface of the wedge block 316, and one end of the second spring 317 is fixedly connected to the surface of the combination block 310;

[0025] When the pedal 306 needs to be stored, the pedal 306 is pushed so that the pedal 306 slides on the surface of the guide rod 307 toward the side of the L-shaped plate 304. At this time, the linkage shell 308 will contact the surface of the wedge block 316. The wedge block 316 can force the second spring 317 to be compressed through its own inclined surface, so that the wedge block 316 is stored in the installation shell 309. In the process of the movement of the pedal 306, the first spring 305 will also be compressed. When the pedal 306 moves to the surface of the linkage shell 308 and no longer contacts the wedge block 316, the second spring 317 will rebound, so that the wedge block 316 can enter the linkage shell 308, so that the pedal 306 can be limited by the linkage shell 308, so that the pedal 306 can be stored in the storage shell 301, thereby making the valve body The space occupied by the pedal 306 is reduced, so that the toilet looks more spacious and tidy, and is convenient for passage and cleaning. When the pedal 306 is needed to drain water, the trigger rod 314 is pushed, so that the trigger rod 314 drives the first connecting plate 313 to move toward the position of the linkage shell 308. In this process, the rotating plate 312 rotates on the surface of the fixed shaft 311, so that the first connecting plate 313 and the second connecting plate 315 can move toward each other, so that the wedge block 316 can be received into the installation shell 309, and the second spring 317 is compressed. At this time, since the linkage shell 308 will no longer be limited by the wedge block 316, the first spring 305 can release its own elastic force, so that the pedal 306 can pop out from the inside of the storage shell 301, so that the operator can normally step on the pedal 306 to operate the trigger plate 303.

[0026] Further, the sealing mechanism 2 includes a sealing spring 201, which is fixed to the left side of the inner wall of the valve body 1, a closing block 202 is fixed to the surface of the sealing spring 201, a closing rod 203 is fixed to the surface of the closing block 202, a blocking block 204 is fixed to the inner wall of the valve body 1, a linkage rod 205 is fixed to the surface of the closing rod 203, a trigger block 206 penetrates one side of the surface of the valve body 1, and an operating rod 207 is fixed to the surface of the trigger block 206;

[0027] When the trigger block 206 is pushed by the trigger plate 303, the operating rod 207 will drive the closing rod 203 to move to the left through the linkage rod 205, so that the sealing spring 201 can be compressed. At this time, the closing rod 203 is no longer in contact with the surface of the blocking block 204, so that the water flow can be directly transported to the drain pipe through the blocking block 204, thereby achieving the opening effect of the valve. After the user stops stepping on the pedal 306, the sealing spring 201 can rebound, so that the closing rod 203 drives the trigger plate 303 to rotate and reset through the linkage rod 205, the operating rod 207 and the trigger block 206.

[0028] Furthermore, a support plate 208 is fixed to the inner wall of the valve body 1, and a plurality of sealing rings 209 are fixed to the inner wall of the support plate 208, and the sealing rings 209 are slidably connected to the surface of the operating rod 207;

[0029] The operating rod 207 can slide on the surface of the sealing ring 209 , and the sealing ring 209 can provide a sealing effect for the surface of the operating rod 207 , so that the water flow will not pass through the support plate 208 and contact the trigger block 206 .

[0030] Furthermore, a telescopic rod 210 is provided inside the sealing spring 201, one end of the telescopic rod 210 is fixedly connected to the inner wall of the valve body 1, and the other end of the telescopic rod 210 is fixedly connected to the surface of the closing block 202;

[0031] When the sealing spring 201 drives the closing block 202 to move, the telescopic rod 210 can be telescoped together with the sealing spring 201, so that the closing block 202 can obtain a guiding effect and avoid positional deviation when the closing rod 203 moves.

[0032] Furthermore, a slide groove 319 is provided on the inner wall of the pedal 306, and sliders 318 are fixed on both upper and lower sides of the surface of the guide rod 307, and the sliders 318 are slidably connected with the surface of the slide groove 319;

[0033] When the pedal 306 slides on the surface of the guide rod 307 , the slider 318 will be able to slide on the surface of the slide groove 319 , thereby preventing the pedal 306 from rotating when moving and preventing the pedal 306 from falling off the surface of the guide rod 307 .

[0034] Furthermore, the sealing spring 201, the first spring 305 and the second spring 317 are all made of stainless steel;

[0035] Stainless steel is not easy to rust, has a smooth surface, is not easy to hide dirt, and is easier to clean and disinfect, which is especially important for a bathroom environment that emphasizes hygiene, ensuring that the sealing spring 201, the first spring 305, and the second spring 317 can have a good service life.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
