When a user sits on the seat 2, the seat 2 is pressed and drives the pivot shaft 3 to move downward against the force of the return mechanism 32 until the pivot shaft 3 reaches the bottom of the adjustment hole 131. At this time, the rear end of the seat 2 is at a lower position, and the rear end of the seat 2 is in contact with the rear portion of the toilet main body 7 (ceramic body). The second trigger 31 descends to the lowest position/descent position, and the second trigger 31 triggers the first trigger 620.

Meanwhile, in the process, the reset mechanism 32 provides a certain damping to slow down the falling of the rear end of the seat ring 2, thereby providing a buffer effect, facilitating the user to gradually adapt to the hard contact between the seat ring 2 and the toilet main body 7, and improving the use experience of the user.

In one embodiment, as shown in fig. 4-10, the grommet 1 has a guide groove 17 extending up and down, and the second trigger end 31 is in clearance fit with the guide groove 17.

The first trigger 620 is held in contact with the second trigger 31 and can be depressed by the second trigger 31 to the trigger position.

In this embodiment, the guide groove 17 serves to guide the second trigger end 31 to slide up and down.

The first trigger end 620 can slide up and down, and can be automatically reset to a higher initial position under the action of the reset element.

When the seat ring 2 or the second trigger end 31 is in the initial position, the first trigger end 620 is in the initial position (higher position), and the control mechanism 62 is in the initial state.

When the seat ring 2 or the second trigger end 31 is in the lowered position or the lowest position, the first trigger end 620 is pressed down to the lowered position or the lowest position by the second trigger end 31, and the control mechanism 62 is in the triggered state.

In one embodiment, the top plate 12 has a guide post 121 extending downward, and the second trigger end 31 has a guide hole, and the guide post 121 is clearance fit in the guide hole to guide the second trigger end 31 to slide up and down.

In one embodiment, the drain valve 61 further includes a drain valve relief tube 614, and the control mechanism 62 is coupled to the drain valve relief tube 614.

When the control mechanism 62 is in the initial state, the drain valve pressure relief pipe 614 is in a stopped drain state.

When the control mechanism 62 is in the activated state, the drain valve relief tube 614 is in a drain state.

In this embodiment, the water pressure is used to control the opening and closing of the drain valve diaphragm 613.

The drain valve 61 has an upper water chamber 615 and a lower water chamber 616 therein. The drain valve outlet pipe 612 is installed at the top of the drain valve 61, and a circle of downward extending ribs 617 are arranged at the water inlet of the drain valve outlet pipe 612. The drain valve diaphragm 613 is disposed between the upper water chamber 615 and the lower water chamber 616, and the drain valve diaphragm 613 has a communication hole 6131.

When the drain valve pressure relief pipe 614 does not drain out, after the water in the upper water chamber 615 enters the lower water chamber 616, the water pressure in the upper water chamber 615 and the water pressure in the lower water chamber 616 are balanced gradually, the drain valve diaphragm 613 seals the barrier 617, and the drain valve outlet pipe 612 does not drain.

When the drain valve relief tube 614 drains outwardly, the water pressure in the lower water chamber 616 decreases and the drain valve diaphragm 613 moves downwardly away from the spacer 617 and the drain valve outlet tube 612 drains.

The control mechanism 62 is used to control the drain valve relief tube 614 to drain or to stop draining, and the control mechanism 62 may be a valve structure connected to the drain valve relief tube 614.

When the control mechanism 62 is in the initial state, the drain valve relief tube 614 does not drain and the drain valve outlet tube 612 does not drain.

When the control mechanism 62 is in the activated state, the drain valve pressure relief tube 614 drains and the drain valve outlet tube 612 drains.

Water discharged from the drain valve relief tube 614 may flow through the tube into the seat overflow tube 14 to clean the ceramic body.

Of course, in the present embodiment, the control mechanism 62 may also configure the first trigger terminal 620, which may be triggered by the second trigger terminal 31 in the above embodiment.

In one embodiment, as shown in FIGS. 11-12, the control mechanism 62 includes a water storage valve 621 having a water storage chamber 6211.

The water storage valve 621 is connected to a water storage valve water inlet pipe 623 and a water storage valve water outlet pipe 624 which communicate with the water storage chamber 6211, a water inlet control valve 625 is provided in the water storage valve water inlet pipe 623, and a water outlet control valve 626 is provided in the water storage valve water outlet pipe 624.

The water storage valve inlet pipe 623 communicates with the drain valve pressure relief pipe 614.

When the control mechanism 62 is in the initial state, the water intake control valve 625 is in the closed state, and the water discharge control valve 626 is in the open state.

When the control mechanism 62 is in the triggered state, the water inlet control valve 625 is in an open state and the water outlet control valve 626 is in a closed state.

In this embodiment, the control mechanism 62 employs a water storage valve 621, which has a delay function to extend the drainage time of the drain valve outlet 612.

In this embodiment, the control mechanism 62 includes a water storage valve 621, a water storage valve water inlet pipe 623, a water storage valve water outlet pipe 624, a water inlet control valve 625, and a water outlet control valve 626.

The water storage valve 621 has a water storage chamber 6211 therein, and the water storage valve water inlet pipe 623 and the water storage valve water outlet pipe 624 are respectively communicated with the water storage chamber 6211. A water inlet control valve 625 is installed in the water storage valve inlet pipe 623 for controlling the opening and closing of the water storage valve inlet pipe 623. A drain control valve 626 is installed in the water storage valve drain pipe 624 for controlling the opening and closing of the water storage valve drain pipe 624. The inlet control valve 625 is alternately opened and closed with the drain control valve 626.

The water storage valve water inlet pipe 623 is communicated with the drain valve pressure relief pipe 614, and the water storage valve water inlet pipe 623 and the drain valve pressure relief pipe 614 can be directly connected or indirectly connected through a pipeline.

If the water inlet control valve 625 and the water outlet control valve 626 are solenoid valves, they are controlled by an electric control mechanism in the control mechanism 62. If the water intake control valve 625 and the water discharge control valve 626 are mechanical valves, they are controlled by mechanical mechanisms in the control mechanism 62. When the first trigger 620 is triggered, the electric control mechanism or the mechanical mechanism in the control mechanism 62 is activated to drive the water inlet control valve 625 and the water outlet control valve 626 to be alternately opened and closed.

When the control mechanism 62 is in the initial state, the water inlet control valve 625 is in the closed state, the water storage valve water inlet pipe 623 is closed, the drain valve pressure relief pipe 614 is not drained, the drain valve diaphragm 613 is closed, and the drain valve water outlet pipe 612 is not drained. At this time, the drain control valve 626 is opened and the water in the water storage chamber 6211 is drained to a predetermined low level by the water storage valve drain pipe 624 to prepare for the next water storage. Water discharged from the water storage valve drain 624 may flow through the pipe into the seat overflow pipe 14, cleaning the ceramic body.

When the control mechanism 62 is in the triggered state, the water inlet control valve 625 is in the opened state, the water storage valve water inlet pipe 623 is opened, the drain valve pressure relief pipe 614 is drained, the drain valve diaphragm 613 is opened, and the drain valve water outlet pipe 612 is drained. At this time, the drain control valve 626 is in a closed state to store water for the water storage chamber 6211. When water is stored in the water storage cavity 6211 to a preset high water level, water does not enter the water storage cavity 6211 any more, and the water inlet control valve 625 is closed. In this process, the time for water in the water storage chamber 6211 to be stored from the low water level to the high water level is a delay time, which can be set according to actual needs. The delay time is substantially the drain time of the drain valve outlet 612. The delay time is determined by the volume of the water storage chamber 6211 and the water flow in the water inlet pipe 623 of the water storage valve.

The height, mounting pattern and mounting position of the water storage valve inlet pipe 623 and the water storage valve outlet pipe 624 can be set according to actual needs, and only one or two mounting patterns are shown in the drawings, and do not necessarily represent that they are mounted as such.

Preferably, the water storage valve drain pipe 43 communicates with the bottom of the water storage cavity 411, and the water storage valve inlet pipe 42 communicates with the top of the water storage cavity 411.

In one embodiment, as shown in FIGS. 13-17, the control mechanism 62 further includes a switching valve 622 coupled to the water storage valve inlet conduit 623 and the water storage valve outlet conduit 624.

The switching valve 622 includes a switching valve housing 6220 having a channel 6221 and a switching shaft 6222 in clearance fit with the channel 6221. The switching shaft 6222 can alternately trigger the drain control valve 626 and the inlet control valve 625.

When the switching shaft 6222 is in the initial position, the switching shaft 6222 triggers the drain control valve 626, and the drain control valve 626 is in the open state.

When the switching shaft 6222 is in the trigger position, the switching shaft 6222 triggers the water intake control valve 625, and the water intake control valve 625 is in an open state.

In this embodiment, switching valve 622 employs a switching shaft 6222 to alternately trigger a water inlet control valve 625 and a water outlet control valve 626. The first trigger 620 is disposed at an upper end of the switching shaft 6222 of the switching valve 622, and the switching shaft 6222 is disposed below the second trigger 31. The first trigger 620 may be an end cap or plate, or the first trigger 620 may be directly the upper end of the switching shaft 6222.

The switching valve 622 has a vertically extending passage 6221 therein, with the body portion of the switching shaft 6222 being a clearance fit in the passage 6221. The upper end of the switching shaft 6222 is above the switching valve housing 6220 for being depressed for triggering.

In one assembly, the shift shaft 6222 and the first trigger end 620 may be depressed downwardly to trigger by the second trigger end 31 of the pivot shaft 3 of the race 2 being movable up and down as described above.

In another assembly, the shift shaft 6222 and the first trigger end 620 may be coupled to a handle that is outside of the toilet, and the user may operate the handle to press the shift shaft 6222 and the first trigger end 620.

When the switching shaft 6222 is in the initial position, the upper end of the switching shaft 6222 is in a higher position above the switching valve housing 6220. After the switching shaft 6222 is triggered by pressing, the upper end of the switching shaft 6222 is in a lower position above the switching valve housing 6220.

The switching shaft 6222 has a trigger portion or a driving portion for triggering the water intake control valve 625 and the water discharge control valve 626, and may be a convex portion, a concave portion, a telescopic member, or the like provided on the switching shaft 6222.

The water storage valve inlet pipe 623 and the water storage valve outlet pipe 624 are connected to the switching valve housing 6220, respectively, and communicate with the passage 6221. Thus, when the switching shaft 6222 is moved to the corresponding position, the trigger/drive on the switching shaft 6222 may trigger the inlet control valve 625 or the drain control valve 626. After the inlet control valve 625 is triggered, the inlet control valve 625 opens the water storage valve inlet pipe 623. After the drain control valve 626 is triggered, the drain control valve 626 opens the water storage valve drain 624.

When the switching shaft 6222 is at the initial position, the switching shaft 6222 triggers the drain control valve 626 to open, while the water inlet control valve 625 is not triggered to remain closed, and the water storage chamber 6211 is in the drain state.

When the switching shaft 6222 is pressed to the trigger position, the switching shaft 6222 triggers the water inlet control valve 625 to open, the water inlet control valve 625 is not triggered to remain closed, and the water storage chamber 6211 is in a water storage state.

So arranged, the alternate switching of the inlet control valve 625 and the drain control valve 626 is controlled by the switching shaft 6222 to control the water storage and drain functions of the water storage chamber 6211.

In one of the embodiments, as shown in fig. 13 to 17, a switching shaft resetting member 6223 for driving the switching shaft 6222 to be reset to the initial position is connected between the switching valve housing 6220 and the switching shaft 6222. A switching shaft return member 6223 is connected between the switching shaft 6222 and the top of the switching valve housing 6220 for urging the switching shaft 6222 up to the initial position for return. The switching valve housing 6220 may be a spring.

In one embodiment, as shown in FIGS. 14-19, the inlet control valve 625 includes a first spool valve 6251 and a first return member 6252 for driving the first spool valve 6251 back to a closed state.

The drain control valve 626 includes a second spool valve 6261 and a second return member 6262 for driving the second spool valve 6261 to return to the closed state.

When the switching shaft 6222 is in the initial position, the first spool 6251 is in the closed state and the second spool 6261 is actuated to be opened by the switching shaft 6222.

When the switching shaft 6222 is in the trigger position, the second spool 6261 is in the closed state and the first spool 6251 is actuated to open by the switching shaft 6222.

In this embodiment, the water inlet control valve 625 and the water outlet control valve 626 are both mechanical slide valve structures, which are specifically as follows:

As shown in fig. 18, the inlet control valve 625 includes a first spool valve 6251 and a first return member 6252. The first spool valve 6251 is slidably mounted in the water storage valve inlet conduit 623. A first through hole 6220a is provided on the switching valve housing 6220, and the water storage valve water inlet pipe 623 is connected to the first through hole 6220a so as to communicate with the passage 6221. The water storage valve water inlet pipe 623 has a first stop portion 6233 at one end near the first through hole 6220a, and a seal ring may be disposed on the first stop portion 6233 as needed.

The first spool 6251 includes a thicker first spool body 6251a and a first spool rod 6251b connected to the first spool body 6251a, the first spool rod 6251b extending toward the first through-hole 6220a and being insertable through the first through-hole 6220a. A first stepped portion 6251c is formed at the junction of the first spool rod 6251b and the first spool body 6251 a. When the first spool valve 6251 is in the closed state, the first stepped portion 6251c is sealed in contact with the first stopper portion 6233, thereby closing the water storage valve inlet pipe 623.

The first return member 6252 is connected to the first spool body 6251a for driving the first spool 6251 to move toward the switching valve housing 6220 side so that the opened first spool 6251 can be automatically returned to the closed position. The first return member 6252 may alternatively be a spring.

As shown in fig. 19, the drain control valve 626 includes a second spool valve 6261 and a second return member 6262. A second spool valve 6261 is slidably mounted in the water storage valve drain 624. A second through hole 6220b is provided in the switching valve housing 6220, and the reservoir valve drain 624 is connected to the second through hole 6220b so as to communicate with the passage 6221. The water storage valve drain pipe 624 has a second stopper portion 6243 at one end near the second through hole 6220b, and a seal ring may be disposed on the second stopper portion 6243 as needed.

The second spool 6261 includes a thicker second spool body 6261a and a second spool rod 6261b connected to the second spool body 6261a, the second spool rod 6261b extending toward the second through hole 6220b and being passable through the second through hole 6220b. A second stepped portion 6261c is formed at the junction of the second spool rod 6261b and the second spool body 6261 a. When the second spool valve 6261 is in the closed state, the second stepped portion 6261c is sealed in contact with the second stopper portion 6243, thereby closing the water storage valve drain 624.

The second restoring member 6262 is connected to the second spool body 6261a for driving the second spool 6261 to move toward the switching valve housing 6220 side so that the opened second spool 6261 can be automatically restored to the closed position. The second restoring member 6262 may be a spring.

When the switching valve 622 is in the initial position:

Under the action of the first return member 6252, the first spool rod 6251b extends into the channel 6221 through the first through hole 6220a, the first stepped portion 6251c is sealed in contact with the first stopper portion 6233, and the first spool valve 6251 closes the water reservoir valve inlet pipe 623 and does not supply water to the water reservoir chamber 6211.

The trigger/drive portion of the shift shaft 6222 is in contact engagement with the second spool rod 6261b of the second spool valve 6261 and pushes the second spool rod 6261b back out of the channel 6221 against the force of the second return member 6262 such that the second stepped portion 6261c is separated from the second stop portion 6243, opening the reservoir valve drain 624 and the reservoir chamber 6211 being drainable.

When the switching valve 622 is in the triggered position:

The trigger/drive portion of the shift shaft 6222 is in contact engagement with the first spool slide bar 6251b of the first spool valve 6251 and pushes the first spool slide bar 6251b back out of the channel 6221 against the force of the first return member 6252 such that the first stepped portion 6251c is separated from the first stop portion 6233 opening the water storage valve inlet conduit 623 and the water storage chamber 6211 can store water.

Under the action of the second return member 6262, the second spool rod 6261b protrudes into the channel 6221 through the second through hole 6220b, the second stepped portion 6261c is sealed in contact with the second stopper portion 6243, the second spool valve 6261 closes the water storage valve drain 624, and the water storage chamber 6211 is not drained.

In one embodiment, as shown in fig. 14-19, a first recess 6222a for receiving an end of the first spool valve 6251 and a second recess 6222b for receiving an end of the second spool valve 6261 are provided on the switching shaft 6222 at intervals.

When the switching shaft 6222 is in the initial position, one end of the first spool 6251 is located in the first recess 6222a, and one end of the second spool 6261 is in contact with the circumferential surface of the switching shaft 6222.

When the switching shaft 6222 is in the activated position, one end of the second spool 6261 is located in the second recess 6222b, and one end of the first spool 6251 is in contact with the circumferential surface of the switching shaft 6222.

In the present embodiment, the switching shaft 6222 is provided with a first concave portion 6222a and a second concave portion 6222b at intervals, and the first concave portion 6222a and the second concave portion 6222b may be annular grooves provided on the switching shaft 6222. The first recess 6222a is adapted to receive an end of the first spool 6251 and the second recess 6222b is adapted to receive an end of the second spool 6261.

When the switching shaft 6222 is in the initial position, the first recess 6222a is aligned with the first through-hole 6220a, and the end of the first spool 6251 (i.e., the end of the first spool rod 6251 b) is inserted into the first recess 6222a through the first through-hole 6220 a. At this time, the first stepped portion 6251c is brought into contact with the first stopper portion 6233 to seal by the first return member 6252, and the first spool valve 6251 closes the water storage valve inlet pipe 623.

When the switching shaft 6222 is in the initial position, the second recess 6222b is offset from the second through hole 6220b and the end of the second spool 6261 (i.e., the end of the second spool rod 6261 b) is clear of the second recess 6222b and contacts the circumferential surface or lobe of the switching shaft 6222, thereby urging the second spool 6261 to compress the second return member 6262 and causing the second stepped portion 6261c to disengage from the second stop portion 6243, the second spool 6261 opening, opening the reservoir valve drain 624.

When the switching shaft 6222 is in the triggered state, the first concave portion 6222a is offset from the first through hole 6220a, the end portion of the first spool valve 6251 (i.e., one end of the first spool rod 6251 b) is separated from the first concave portion 6222a and contacts the circumferential surface or convex portion of the switching shaft 6222, thereby driving the first spool valve 6251 to compress the first return member 6252 and causing the first stepped portion 6251c to separate from the first stopper portion 6233, the first spool valve 6251 to open, and the water storage valve water inlet pipe 623 to open.

When the switching shaft 6222 is in the activated state, the second recess 6222b is aligned with the second through-hole 6220b, and the end of the second spool 6261 (i.e., the one end of the second spool rod 6261 b) is inserted into the second recess 6222b through the second through-hole 6220 b. At this time, the second stepped portion 6261c is brought into contact with the second stopper portion 6243 to seal by the second return member 6262, and the second spool valve 6261 closes the water storage valve drain pipe 624.

In one embodiment, as shown in fig. 13-17, the water storage valve inlet conduit 623 includes a first inlet conduit 6231 and a second inlet conduit 6232.

The first water inlet pipe 6231 communicates with the drain valve relief pipe 614 and the first recess 6222a, and the second water inlet pipe 6232 communicates with the water storage chamber 6211 and the first recess 6222a.

The inlet control valve 625 is in the first inlet conduit 6231 or in the second inlet conduit 6232.

In this embodiment, the first concave portion 6222a serves as a water chamber. The water storage valve inlet pipe 623 comprises a first inlet pipe 6231 and a second inlet pipe 6232, the switching valve housing 6220 being connected between the first inlet pipe 6231 and the second inlet pipe 6232. The first inlet tube 6231 communicates with the drain valve relief tube 614, and the first inlet tube 6231 also communicates with the first recess 6222 a. One end of the second water inlet pipe 6232 communicates with the water storage chamber 6211, and the other end communicates with the first recess 6222 a.

When the inlet control valve 625 is opened, water in the drain valve relief tube 614 may enter the water storage chamber 6211 via the first inlet tube 6231, the first recess 6222a, and the second inlet tube 6232.

As shown in fig. 14-15, a water inlet control valve 625 may be disposed in the second water inlet conduit 6232. In this structure, the direction of the inflow water flow is opposite to the acting direction of the first return member 6252, so that the first return member 6252 needs to provide a larger elastic force to overcome the water pressure of the inflow water, so as to avoid the first slide valve 6251 from being flushed by the water flow, so as to ensure that the first slide valve 6251 can be closed.

Preferably, as shown in fig. 16-17, a inlet control valve 625 is disposed in the first inlet conduit 6231. In this structure, the direction of the flow of the inlet water is the same as the direction of the action of the first return member 6252, and the first return member 6252 acts on the first spool valve 6251 together with the water pressure of the inlet water, so that the first spool valve 6251 is kept in the closed state.

In one embodiment, as shown in fig. 13-17, the water storage valve drain 624 includes a first drain 6241 and a second drain 6242.

The first drain pipe 6241 is connected to the switching valve housing 6220 and communicates with the second recess 6222b, and the second drain pipe 6242 communicates the water storage chamber 6211 with the second recess 6222b.

The drain control valve 626 is in the first drain 6241 or in the second drain 6242.

In this embodiment, the second concave portion 6222b serves as a water chamber. The water storage valve drain 624 includes a first drain 6241 and a second drain 6242, with the switch valve housing 6220 connected between the first drain 6241 and the second drain 6242. The first drain pipe 6241 is connected to the switching valve housing 6220, and the first drain pipe 6241 communicates with the second recess 6222 b. One end of the second drain pipe 6242 communicates with the water storage chamber 6211, and the other end communicates with the second recess 6222 b.

When the drain control valve 626 is opened, water in the water storage chamber 6211 may be drained through the second drain tube 6242, the second recess 6222b, and the first drain tube 6241. A first drain 6241 may be in communication with the seat overflow tube 14 to drain water into the ceramic body for flushing.

A drain control valve 626 may be disposed in the first drain pipe 6241. In this structure, the direction of the water flow of the drain is opposite to the acting direction of the second return member 6262, and the second return member 6262 needs to provide a larger elastic force against the water pressure of the inlet water to avoid the second spool valve 6261 from being flushed by the water flow, so as to ensure that the second spool valve 6261 can be closed.

Preferably, as shown in fig. 14-16, the drain control valve 626 is disposed in the second drain 6242. In this structure, the direction of the flow of the drain water is the same as the direction of the action of the second return member 6262, and the second return member 6262 acts on the second spool valve 6261 together with the water pressure of the drain water, so that the second spool valve 6261 is kept in the closed state.

In one preferred embodiment, the water inlet control valve 625 is arranged in the first water inlet pipe 6231, the water outlet control valve 626 is arranged in the second water outlet pipe 6242, and the closing direction of the water inlet control valve 625 and the water outlet control valve 626 is consistent with the water flow direction at the corresponding positions, so that the acting force of the reset piece can be reduced, and the sealing is facilitated.

In one embodiment, as shown in fig. 14-17, sealing rings 6224 are respectively arranged on two sides of the first concave portion 6222a and two sides of the second concave portion 6222b on the switching shaft 6222, so as to improve the sealing performance, and ensure that water in the first concave portion 6222a and the second concave portion 6222b cannot flow out through the channel 6221.

In one embodiment, as shown in fig. 14-16, the water storage chamber 6211 includes a lower water storage chamber 6211a and an upper water storage chamber 6211b, with a diaphragm aperture 6213 in the diaphragm 6212 between the lower water storage chamber 6211a and the upper water storage chamber 6211 b.

The water storage valve inlet pipe 623 and the water storage valve outlet pipe 624 communicate with the lower water storage chamber 6211a, respectively.

The lower water storage chamber 6211a is provided with a float valve 6214 for opening and closing the diaphragm through hole 6213, the upper water storage chamber 6211b is provided with a water float 6215, a connecting rod 6216 is connected between the float valve 6214 and the water float 6215, and a gap between the connecting rod 6216 passes through the diaphragm through hole 6213.

When water is stored in the upper water storage chamber 6211b to a preset level, the float valve 6214 closes the diaphragm through hole 6213.
