Further, as shown in fig. 4 and 8, the driving rod 332 may be used to drive the switching plate 331 to rotate between the first position and the second position; wherein when the switching baffle 331 is located at the first position, the water passing area of the drainage port 311 is larger than the water passing area of the drainage port 311 when the switching baffle 331 is located at the second position, and when the switching baffle 331 is located at the second position, the water passing area of the drainage port 311 is not zero, that is, the switching baffle 331 cannot close the drainage port 311, so that the brush ring injector 3 can discharge water with small flow in a period of time after the drain outlet 2111 of the drain valve 2 is closed and before the water outlet of the water inlet valve body 11 is stopped, thereby ensuring the cleaning effect on the toilet bowl. The switch plate 331 may rotate only between the first position and the second position, and the switch plate 331 may not close the drainage port 311 when the switch plate 331 is located at the second position, which may be achieved by setting a limiting structure and controlling the structure of the switch plate 331, which is a conventional technical means for those skilled in the art, and will not be described herein.
The following description is made in detail of the working process of the present invention in order to facilitate understanding of the present invention, with reference to fig. 1 and 3 to 8.
In the initial state, as shown in fig. 1,3 and 4, the water outlet 2111 of the water draining valve 2 is blocked by the water stopping component 22, the water draining valve 2 is in a closed state, and the water draining pontoon 23 of the water draining valve 2 is at a high position under the action of buoyancy; the water inlet pontoon 13 is positioned at a high position under the action of buoyancy, so that the driving end 121 of the lifting rod 12 is positioned at a high position, and the water inlet valve body 11 stops water outlet; the balancing weight 3321 on the driving rod 332 is positioned at a low position to enable the switching baffle 331 to be positioned at a second position, and at the moment, the water passing area of the drainage port 311 of the brush ring injector 3 is small;
As shown in fig. 5, 6 and 8, when the drain button 24 is pressed, the drain button 24 moves down to drive the second end of the connecting rod 25 to move down, the second end of the connecting rod 25 moves down to move up the first end of the connecting rod 25 to move up the water stop assembly 22, so that the drain valve 2 is in an open state, and at this time, the fastening part 221 of the water stop assembly 22 fastens the hanger 231 on the drain buoy 23, so that the drain valve 2 is kept in an open state, and thus water in the water tank flows out from the drain outlet 2111; simultaneously, the downward movement of the water discharge button 24 can enable the pressing piece 241 to press the driving end 121 of the lifting rod 12 of the water inlet valve 1, so that the driving end 121 of the lifting rod 12 moves downward to open the water inlet valve body 11, so that the water inlet valve body 11 is enabled, and at the moment, the water inlet pontoon 13 moves downward along with the downward movement of the driving end 121 of the lifting rod 12, so that the water inlet pontoon 13 is in a low position; meanwhile, the second end of the connecting rod 25 moves downwards to drive the limiting piece 27 to move downwards, so that the limiting piece 27 moves downwards to enable the limiting piece 271 to press the second end of the driving rod 332, so that the switching baffle 331 rotates forwards to a first position, the water passing area of the water inlet opening 311 is large at the moment, the balancing weight 3321 on the first end of the driving rod 332 moves upwards, water flow of the water inlet valve body 11 directly flows into the jet pipe 32 at the moment, water flow of the jet pipe 32 is accelerated by the nozzle 321 to form high-speed water flow to be sprayed to the water guiding opening 311 of the brush ring pipe 31, the high-speed water flow enables the brush ring pipe 31 to generate negative pressure to pump water of the water tank into the brush ring pipe 31 to enlarge the flow of the brush ring pipe 31, and therefore the pan surface of the toilet bowl is flushed in a large flow;
As shown in fig. 7 and 8, after the drain button 24 is pressed, the drain button 24 moves upwards and resets under the action of the reset spring 26, and the water stopping component 22 cannot fall down because the buckling part 221 buckles the hanging frame 231 of the drain buoy 23, the water stopping component 22 limits the limiting piece 27 through the connecting rod 25, so that the limiting piece 271 of the limiting piece 27 always presses the second end of the driving rod 332 to enable the drainage port 311 of the brush ring injector 3 to be in a large water passing area state, and in addition, the water level in the water tank drops to a certain extent at the moment to enable the water inlet buoy 13 to be kept at a low position, so that the water inlet valve body 11 keeps water, and water flow of the water inlet valve body 11 always flows into the injection pipe 32 to ensure flushing of the toilet bowl surface;
As the water in the toilet tank flows out from the water outlet 2111 and the brush ring injector 3, the water level of the tank continuously drops, the water discharge pontoon 23 also drops, and when the water level in the tank drops to a certain water level line, the hanging frame 231 on the water discharge pontoon 23 is separated from the buckling part 221 of the water stop assembly 22, so that the water stop assembly 22 drops to close the water outlet 2111 of the water discharge valve 2; simultaneously, the water stopping assembly 22 moves downwards to enable the second end of the connecting rod 25 to drive the limiting piece 27 to move upwards, so that the limiting piece 271 of the limiting piece 27 does not press the second end of the driving rod 332 any more, at the moment, under the action of gravity of the balancing weight 3321, the first end of the driving rod 332 moves downwards to enable the second end of the driving rod 332 to move upwards and enable the switching baffle 331 to reversely rotate to a second position, so that the water passing area of the drainage port 311 of the brush ring injector 3 becomes smaller, at the moment, because the water level in the water tank is low, the water inlet pontoon 13 is still at a low position, the water inlet valve body 11 still discharges water, most of water of the water inlet valve body 11 flows into the water tank of the toilet to store water, so that the water level in the water tank slowly rises, and a small part of the water flow of the water inlet valve body 11 drives the water tank 2 to enter the brush ring pipe 31, and the water is discharged in a small flow amount to keep flushing the toilet bowl surface of the toilet; when the water level in the water tank rises to a certain water level line, the water inlet pontoon 13 drives the driving end 121 of the lifting rod 12 to move upwards to an initial position, so that the water inlet valve body 11 stops water inlet, and the brush ring injector 3 does not discharge water any more.
The above examples and drawings are not intended to limit the form or form of the present invention, and any suitable variations or modifications thereof by those skilled in the art should be construed as not departing from the scope of the present invention.
