detailed description

The technical solution of the present invention will be described in further detail below with reference to FIG. 1 to FIG. 3 , but is not limited to this description.

A flat water tank toilet, comprising a toilet body 26, a water tank 27 and a toilet bowl 28 are arranged on the toilet body 26, a drain valve 29 and a water inlet valve 30 are arranged in the water tank 27, and the water inlet valve 30 is connected with a water tank filling pipe 31 , the drain valve 29 is connected with a control switch 32, and the water tank 27 is provided with a flushing assembly; the flushing assembly includes a flushing pipe 2 and a small flushing outlet pipe 33, and the outlet of the flushing pipe 2 is located on the upper side of the water tank 27. The lower edge of the seat ring of the urinal 28 and the small flushing water pipe 33 are provided with a flushing solenoid valve 34 , and the control switch 32 is connected to the flushing solenoid valve 34 .

The toilet body 26 is also provided with a controller, the controller is connected to the flush solenoid valve 34, and the control switch 32 is connected to the controller. The controller can realize the presetting of the flushing process, and coordinate the drainage action of the drain valve 29 and the water intake action of the flushing solenoid valve 34. For example, when the big flush button of the control switch 32 is pressed, the controller controls the flushing action. The water solenoid valve 34 is opened for a certain period of time, and the water is slightly discharged from the flushing assembly, and the toilet seat is slightly preflushed from top to bottom to achieve a full flushing effect, which can simplify the operation process.

The water tank filling pipe 31 is communicated on the small flushing water pipe 33 . After the water tank filling pipe 31 is connected with the small flushing water pipe 33, the small flushing water pipe 33 is connected to the water pipe joint of the toilet. Water, when the flush solenoid valve 34 is opened and the water inlet valve 30 is closed, a small flush is realized, so that only one water pipe connection is needed, which is more in line with the layout of a traditional toilet.

The flushing assembly includes a main pipe 1, one side of the main pipe 1 is connected with a flushing pipe 2, and the main pipe 1 is also connected with a pressure relief pipe 3, and the end of the pressure relief pipe 3 connected with the main pipe 1 is a pressure relief water inlet 4, and the pressure relief water inlet The size of 4 is smaller than the size of the cross section of the pressure relief pipe 3, the other end of the pressure relief pipe 3 is a pressure relief water outlet 5, and the periphery of the pressure relief water outlet 5 extends inwardly with a retaining wall 6; the pressure relief pipe 3 is provided with Plug 7, the size of the plug 7 is larger than the pressure relief water inlet 4, and smaller than the cross section of the pressure relief pipe 3, the front end of the plug 7 is pressed against the pressure relief water inlet 4, and the center of the rear end of the plug 7 is vertically connected There is a sliding column 8 with a cross-shaped cross-section.

One end of the pressure relief spring 9 presses against the plug 7. At the rear end, the other end of the pressure relief spring 9 presses against the retaining wall 6 . When using the flushing solenoid valve 34 to enter water and perform small flushing, the water pressure may be too high to cause jetting. Perform pressure relief control. When the water flow passes through the main pipe 1, it will not only flow to the flushing pipe 2, but also impact the plug 7 from the pressure relief inlet 4. When the water pressure is high, the plug 7 will be impacted by the water flow and retreat, and the cross section of the slide bar It is cross-shaped, so that the slide bar can not only slide back and forth stably in the pressure relief water outlet 5, but also leave a gap with the pressure relief water outlet 5. When the plug 7 leaves the pressure relief water inlet 4, the plug 7 The gap between the pressure relief pipe 3 forms a passage from the pressure relief water inlet 4 to the pressure relief water outlet 5, and the water flow is returned to the water tank 27 through this waterway, which reduces the water pressure for the water outlet of the flushing pipe 2 and also Supplementing the water yield of the water tank 27 does not cause waste, and the flushing electromagnetic valve 34 is fully utilized.

The lower end of the main pipe 1 is sleeved with a water guide pipe 10, and the lower end of the water guide pipe 10 is the water inlet end of the flushing assembly; the main pipe 1 is provided with an anti-backflow core, and the anti-backflow core includes a baffle plate 11 and an anti-backflow spring 12 to prevent backflow.

The direction of the water outlet is adjusted by the front end of the rotating end 18. When the rotating end 18 is moved, the relative position of the water inlet and the outlet pipe on the rotating end 18 will also change continuously. The change of the water flow area will change the water pressure, resulting in stronger or stronger Softer impact force, and the direction of the water outlet will change accordingly, resulting in different water flow routes, cooperate with the pressure relief pipe 3, and flexibly adjust the strength and direction of the water flow on the premise of preventing the flushing pipe 2 from spraying water, to meet different needs Flushing required.

The inner end of the rotating end 18 is embedded in the accommodating cavity 15, and the outer end of the rotating end 18 is covered with an adjusting nut 17.
