The installation relationship among all parts on the toilet bowl is as follows:

as shown in fig. 3 to 5, the first driving key 311 and the second driving key 312 are disposed side by side and are both mounted on the bracket 322 to be movable up and down, the first rod 331 is mounted on the mounting bracket 320 to be movable up and down through the middle portion, and one end of the first rod 331 is located below the first driving key 311 and the second driving key 312 and is both matched with the first driving key 311 and the second driving key 312. The first blocking rod 342 is obliquely arranged below the first driving key 311 and is hinged to the overflow pipe 321 in a manner of swinging up and down, and the first protruding column 3111 is abutted to the upper end of the first blocking rod 342 in a downward direction. The second stop lever 352 is obliquely arranged below the second driving key 312 and is hinged to the overflow pipe 321 in a manner of swinging up and down, and the second convex column 3121 is pressed against the upper end of the second stop lever 352 downwards. The first valve cover 362 is located below the second valve cover 372, and one end of the first valve cover 362 and one end of the second valve cover 372 are both hinged to the overflow pipe 321, so that the first valve cover 362 can be opened and closed on the first valve cylinder 361, and the second valve cover 372 can be opened and closed on the second valve cylinder 371. The upper ends of the first and second connection strings 341 and 351 are correspondingly connected to the two ends of the second rod 332, and the lower ends of the first and second connection strings 341 and 351 are respectively connected to the other end of the first valve cover 362 and the other end of the second valve cover 372. The first swing link 343 is pivotally mounted on the first valve cover 362 through a lower end thereof, two sets of limiting ribs 344 at the lower end of the first swing link 343 are used for limiting a swing stroke of the first swing link 343, and an upper end of the first swing link 343 corresponds to a lower end of the first stopper lever 342. The second swing rod 353 is pivotally mounted on the second valve cover 372 through the lower end, two groups of limiting convex ribs at the lower end of the second swing rod 353 are used for limiting the swing stroke of the second swing rod 353, and the upper end of the second swing rod 353 corresponds to the lower end of the second stop lever 352. As shown in fig. 1 to 5, the lower end of the first valve cylinder 361 is attached to the injection mounting port 121 and sealed by an injection seal 365. The lower end of the second valve cylinder 371 is attached to the gasket attachment opening 122 and sealed by a gasket seal 373. The inlet valve 200 is installed in the water containing chamber 120. The lower portion of the overflow pipe 321 communicates with the second valve cylinder 371. The first driving button 311 is used for stool flushing and the second driving button 312 is used for urine flushing.

The action mode and the effect of the toilet bowl are as follows:

as shown in fig. 4, when the stool is flushed, the first driving key 311 is pressed, the first driving key 311 pushes the driving rod 330 and the first stopper 342 to swing, the second stopper 352 does not swing, the second lever 332 opens the first valve cover 362 and the second valve cover 372 by pulling up the first connecting rope 341 and the second connecting rope 351, and the first swing rod 343 and the second swing rod 353 swing back at the upper ends under the inertia effect. Since the lower end of the first blocking lever 342 swings upward, the swing stroke of the upper end of the first swing lever 343 is avoided, so that the first swing lever 343 swings backward to the maximum position beyond the lower end of the first blocking lever 342, and the first valve cover 362 is opened to the maximum opening angle. Since the second stopper 352 does not swing, the lower end of the second stopper 352 interferes with the swing stroke of the upper end of the second swing lever 353, the upper end of the second swing lever 353 swings backwards to abut against the side surface of the lower end of the second stopper 352 and cannot swing to the maximum position, and the second valve cover 372 cannot be opened to the maximum opening angle. At this time, the water in the water containing chamber 120 is discharged from the first and second valve cylinders 361 and 371 at the same time. One path is sprayed out from the wash ring washing hole 112 through the wash ring pipe 140 to wash the side of the urination and defecation cavity 110, and the other path is sprayed out from the spray opening 111 through the spray pipe 130 to push the dirt at the bottom of the urination and defecation cavity 110 to be discharged, and water is enabled to quickly fill the siphon pipe 150. When the first driving key 311 is released, the second valve cover 372 falls back to close the second valve cylinder 371 preferentially under the action of the counterweight structure, and the first valve cover 362 lags back to close the first valve cylinder 361. After the second drain valve 370 is closed, the first drain valve 360 continues to drain water, and the injection port 111 continuously injects water forcefully to prevent blockage. The water level in the water containing cavity 120 continuously drops, and the first valve cover 362 partially exposes out of the water surface, so that the buoyancy force applied to the first valve cover 362 drops, and finally the first valve cover 362 rapidly drops to close the first valve barrel 361, and the water outlet 111 stops water outlet (see fig. 6 and 7, during the swinging and dropping process of the first valve cover 362, the opening angle of the first valve cover 362 gradually decreases, and the height of the first swing rod 343 is lower when the first swing rod 343 is kept at the maximum swinging angle, so that the upper end of the first swing rod 343 is lower than the lower end of the first stop lever 342 during the swinging back process, the first swing rod 343 cannot be blocked by the lower end of the first stop lever 342, the first swing rod 343 can smoothly swing back, and the first valve cover 362 can be covered on the first valve barrel 361). Namely: a large proportion of water is discharged from the first water discharge valve 360 through the injection port 111, a small proportion of water is discharged from the second water discharge valve 370 through the washer flushing hole 112, the urination and defecation cavity 110 is not blocked, and the inner side surface of the urination and defecation cavity 110 can be flushed clean.

As shown in fig. 5, when the urine is flushed, the second driving key 312 is pressed, the second driving key 312 pushes the driving rod 330 and the second stopper 352 to swing, the first stopper 342 does not swing, the driving rod 330 opens the first valve cover 362 and the second valve cover 372 by pulling up the first connecting rope 341 and the second connecting rope 351, and the first swing link 343 and the second swing link 353 swing back at the upper ends under the inertia effect. Since the lower end of the second stopper 352 swings upward, the swing stroke of the upper end of the second swing lever 353 is avoided, so that the second swing lever 353 swings backward to the maximum position beyond the lower end of the second stopper 352, and the second valve cover 372 is opened to the maximum opening angle. Since the first blocking lever 342 does not swing, and the lower end of the first blocking lever 342 interferes with the swing stroke of the upper end of the first swing lever 343, the upper end of the first swing lever 343 swings backward to a side abutting against the lower end of the first blocking lever 342 and cannot swing to the maximum position, and the first valve cover 362 cannot be opened to the maximum opening angle. At this time, the water in the water containing chamber 120 is discharged from the first and second valve cylinders 361 and 371 at the same time. One path is sprayed out from the wash ring washing hole 112 through the wash ring pipe 140 to wash the side of the urination and defecation cavity 110, and the other path is sprayed out from the spray opening 111 through the spray pipe 130 to push the dirt at the bottom of the urination and defecation cavity 110 to be discharged, and water is enabled to quickly fill the siphon pipe 150. When the second actuation key 312 is released, the first valve cap 362 preferentially falls back to close the first valve cylinder 361 and the second valve cap 372 lags behind the second valve cylinder 371 due to the counterweight structure. The siphon pipe 150 gradually forms a siphon and then the first valve cap 362 drops down quickly, and the injection port 111 stops injecting after the first drain valve 360 is closed. The second drain valve 370 continues to drain, the rim flushing hole 112 continuously discharges water to flush splashed dirt on the inner side of the urine and feces cavity 110, and simultaneously, the water at the bottom of the urine and feces cavity 110 is continuously sucked away by the siphon pipe 150 under the siphon action. The water level in the water containing cavity 120 continues to drop, the second valve cover 372 partially exposes out of the water, the buoyancy of the second valve cover 372 drops, the second valve cover 372 quickly drops to close the second valve cylinder 371, the second drain valve 370 is closed, and the water outlet of the washing ring flushing hole 112 is gradually stopped. Namely: a small proportion of the water is discharged from the first drain valve 360 through the injection port 111, and a large proportion of the water is discharged from the second drain valve 370 through the washer flushing hole 112, so that the urination and defecation cavity 110 can be better flushed clean.

The toilet bowl has better flushing effect when used for flushing urine and flushing excrement. Moreover, the water inlet of the first drain valve 360 is lower than the water inlet of the second drain valve 370, so the displacement of the stool flushing is greater than that of the urine flushing, and the urine flushing is more water-saving. After the flushing is finished, the water inlet valve 200 feeds water into the water containing cavity 120, and the water level in the water containing cavity 120 is raised to a working state. The first drain valve 360 is a spray drain valve, the second drain valve 370 is a wash ring drain valve, and water is stored in the water seal storage section of the spray pipe 130.

When the excrement flushing is carried out, the opened wash ring drain valve and the opened injection drain valve are closed in a delayed mode, so that the purposes of increasing the drainage quantity of the injection drain valve and reducing the drainage quantity of the wash ring drain valve are achieved, and the injection drain valve and the wash ring drain valve can be opened simultaneously; when the urinal is flushed, the opened spraying drain valve and the opened washing ring drain valve are closed in a delayed manner, so that the aims of reducing the drainage quantity of the spraying drain valve and increasing the drainage quantity of the washing ring drain valve are fulfilled, and the spraying drain valve and the washing ring drain valve can be opened simultaneously; or can be, wash the circle drain valve and adopt automatically controlled valve with the injection drain valve, the mode of controlling through the control panel realizes above-mentioned washing method, all can realize the purpose of this application above, and its purpose does not break away from the utility model discloses a design idea is no longer repeated here, all should belong to the protection within range of this application.

In an exemplary embodiment, as shown in fig. 4, when the stool is flushed, the first driving key 311 is driven to operate, the driving rod 330 drives the first driving assembly 340 and the second driving assembly 350 to open the injection drain valve and the wash rim drain valve respectively, and under the action of the first driving assembly 340 and the second driving assembly 350, the injection drain valve lags behind the close of the wash rim drain valve, so that the water discharge amount of the injection drain valve is increased, and the water discharge amount of the wash rim drain valve is reduced.

For example, as shown in fig. 4, when the stool is flushed, the first driving key 311 is pressed, the driving lever 330 and the first blocking lever 342 are pushed by the first driving key 311 to swing, the driving lever 330 opens the first valve cover 362 and the second valve cover 372 by pulling up the first connecting rope 341 and the second connecting rope 351, and the first swing link 343 and the second swing link 353 swing back at the upper ends under the inertia effect. The lower end of the first blocking lever 342 swings upward to avoid the swing stroke of the upper end of the first swing lever 343, so that the first swing lever 343 crosses the lower end of the first blocking lever 342 to swing backward to the maximum position, and the first valve cover 362 is opened to the maximum opening angle. The second stopper 352 does not swing, and the lower end of the second stopper 352 interferes with the swing stroke of the upper end of the second swing lever 353, so that the upper end of the second swing lever 353 swings backwards to the side surface abutting against the lower end of the second stopper 352 and cannot swing to the maximum position, and the second valve cover 372 cannot open the cover to the maximum opening angle.

At this time, the water in the water containing chamber 120 is discharged from the first and second valve cylinders 361 and 371 at the same time. One path is sprayed out from the wash ring washing hole 112 through the wash ring pipe 140 to wash the side of the urination and defecation cavity 110, and the other path is sprayed out from the spray opening 111 through the spray pipe 130 to push the dirt at the bottom of the urination and defecation cavity 110 to be discharged, and water is enabled to quickly fill the siphon pipe 150. When the first driving key 311 is released, the second valve cover 372 falls back to close the second valve cylinder 371 preferentially under the action of the counterweight structure, and the first valve cover 362 lags back to close the first valve cylinder 361. After the washing ring drain valve is closed, the injection drain valve continues to drain water, and the injection port 111 continuously injects forcefully to prevent blockage. The water level in the water containing cavity 120 continuously drops, and the first valve cover 362 partially exposes out of the water surface, so that the buoyancy force applied to the first valve cover 362 drops, and finally the first valve cover 362 rapidly drops to close the first valve barrel 361, and the water outlet 111 stops water outlet (see fig. 6 and 7, during the swinging and dropping process of the first valve cover 362, the opening angle of the first valve cover 362 is reduced, and the height of the first swing rod 343 is lower when the first swing rod 343 is kept at the maximum swinging angle, so that the upper end of the first swing rod 343 is lower than the lower end of the first stop lever 342 during the swinging back process, the first swing rod 343 cannot be blocked by the lower end of the first stop lever 342, the first swing rod 343 can smoothly swing back, and the first valve cover 362 can be covered on the first valve barrel 361). Namely: a large proportion of water is discharged from the water discharge valve through the injection port 111, a small proportion of water is discharged from the water discharge valve of the washing ring through the washing ring flushing hole 112, the urination and defecation cavity 110 is not blocked, and the inner side surface of the urination and defecation cavity 110 can be flushed completely.

For example, as shown in fig. 4, the first valve cylinder 361 and the second valve cylinder 371 have the same inner diameter, and when the stool flushing is performed, the discharge amount of the injection discharge valve is larger than that of the wash rim discharge valve.

In an exemplary embodiment, as shown in fig. 5, when urine flushing is performed, the second driving key 312 is driven to act, the driving rod 330 drives the first driving assembly 340 and the second driving assembly 350 to open the injection drain valve and the wash-ring drain valve respectively, and under the action of the first driving assembly 340 and the second driving assembly 350, the wash-ring drain valve lags behind the closing of the injection drain valve, so that the water discharge amount of the wash-ring drain valve is increased, and the water discharge amount of the injection drain valve is reduced.

For example, as shown in fig. 5, when the urine flushing is performed, the second driving key 312 is pressed, the second driving key 312 pushes the driving rod 330 and the second stopper 352 to swing, the driving rod 330 opens the first valve cover 362 and the second valve cover 372 by pulling up the first connecting rope 341 and the second connecting rope 351, and the first swing link 343 and the second swing link 353 swing back at the upper end under the inertia effect. The lower end of the second stopper 352 swings upward to avoid the swing stroke of the upper end of the second swing lever 353, so that the second swing lever 353 swings backward to the maximum position beyond the lower end of the second stopper 352, and the second valve cover 372 opens the cover to the maximum opening angle. The first blocking lever 342 does not swing, and the lower end of the first blocking lever 342 interferes with the swing stroke of the upper end of the first swing lever 343, so that the upper end of the first swing lever 343 swings backwards to the side abutting against the lower end of the first blocking lever 342 and cannot swing to the maximum position, and the first valve cover 362 cannot open to the maximum opening angle.

At this time, as shown in fig. 5, the water in the water containing chamber 120 is simultaneously discharged from the first and second valve cylinders 361 and 371. One path is sprayed out from the wash ring washing hole 112 through the wash ring pipe 140 to wash the side of the urination and defecation cavity 110, and the other path is sprayed out from the spray opening 111 through the spray pipe 130 to push the dirt at the bottom of the urination and defecation cavity 110 to be discharged, and water is enabled to quickly fill the siphon pipe 150. When the second actuation key 312 is released, the first valve cap 362 preferentially falls back to close the first valve cylinder 361 and the second valve cap 372 lags behind the second valve cylinder 371 due to the counterweight structure. The siphon pipe 150 gradually forms a siphon and then the first valve cap 362 drops down quickly, and the injection port 111 stops injecting after the injection drain valve is closed. The water is continuously discharged from the washing ring discharging valve, the washing ring flushing hole 112 continuously discharges water to flush splashed dirt on the inner side surface of the urine and excrement cavity 110, and simultaneously, the water at the bottom of the urine and excrement cavity 110 is continuously sucked away by the siphon pipeline 150 under the siphon action. The water level in the water containing cavity 120 continuously drops, the second valve cover 372 partially exposes out of the water surface, the buoyancy of the second valve cover 372 drops, the second valve cover 372 quickly drops to close the second valve cylinder 371, the water discharging valve of the washing ring is closed, and the washing ring flushing hole 112 gradually stops water discharging. Namely: a small proportion of water is discharged from the jet water discharge valve through the jet port 111, and a large proportion of water is discharged from the wash ring water discharge valve through the wash ring flushing hole 112, so that the urination and defecation cavity 110 can be better flushed clean.

For example, as shown in fig. 5, the first valve cylinder 361 and the second valve cylinder 371 have the same inner diameter, and when urine flushing is performed, the water discharge amount of the rim flushing water discharge valve is greater than the water discharge amount of the jet water discharge valve.
