In one of the embodiments, as shown in
Between the seat base 1 and the pivot shaft 3 is assembled a reset mechanism 32 for driving the pivot shaft 3 to move upward and reset.
The control mechanism 62 comprises a first trigger end 620 and the pivot shaft 3 is provided with a second trigger end 31 for triggering the first trigger end 620.
When the seat 2 is in an initial position, the first trigger end 620 is in an initial state.
When the seat 2 is in a descending position, the second trigger end 31 triggers the first trigger end 620 and puts the control mechanism 62 in the triggered state.
In this embodiment, the control mechanism 62 comprises the first trigger end 620, and the control mechanism 62 switches from the initial state to the triggered state when the first trigger end 620 is triggered by pressing.
The seat 2 can be moved up and down with respect to the seat base 1 so that the control mechanism 62 can be triggered.
A longer pivot shaft 3 can be provided at the rear of the seat 2 as needed, or a shorter pivot shaft 3 can be provided on the left and right sides of the rear of the seat 2 respectively.

The drain valve outlet pipe 612 is mounted at the top of the drain valve 61, and the inlet of the drain valve outlet pipe 612 has a circle of baffle rib 617 extending downward. The drain valve diaphragm 613 is in the upper water cavity 615 and the lower water cavity 616, and the drain valve diaphragm 613 has a communication hole 6131.
When the drain valve pressure relief pipe 614 does not drain outward, the water in the upper water cavity 615 enters the lower water cavity 616, gradually making the water pressure in the upper water cavity 615 and the water pressure in the lower water cavity 616 balance, such that the drain valve diaphragm 613 seals the baffle rib 617, and the drain valve outlet pipe 612 does not drain.
When the drain valve pressure relief pipe 614 drains outward, the water pressure in the lower water cavity 616 decreases, the drain valve diaphragm 613 leaves the baffle rib 617 downward, and the drain valve outlet pipe 612 drains.
The control mechanism 62 is used to control the drain valve pressure relief pipe 614 to drain or stop draining, and the control mechanism 62 may be a valve structure connected to the drain valve pressure relief pipe 614.
When the control mechanism 62 is in the initial state, drain valve pressure relief pipe 614 does not drain and drain valve outlet pipe 612 does not drain.
When the control mechanism 62 is in the triggered state, the drain valve pressure relief pipe 614 drains and the drain valve outlet pipe 612 drains.
The water drained from the drain valve pressure relief pipe 614 can flow into the seat base overflow pipe 14 through the pipe to clean the ceramic body.
Certainly, in this embodiment, the control mechanism 62 can also be provided with a first trigger end 620, which can be triggered by the second trigger end 31 in the above embodiment.
In one of the embodiments, as shown in
The water storage valve 621 is connected to a water storage valve inlet pipe 623 and a water storage valve drain pipe 624 in communication with the water storage cavity 6211, with an inlet control valve 625 in the water storage valve inlet pipe 623 and a drain control valve 626 in the water storage valve drain pipe 624.
The water storage valve inlet pipe 623 is in communication with the drain valve pressure relief pipe 614.
When the control mechanism 62 is in the initial state, the inlet control valve 625 is in a closed state and the drain control valve 626 is in an opened state.
When the control mechanism 62 is in the triggered state, the inlet control valve 625 is in an opened state and the drain control valve 626 is in a closed state.
In this embodiment, the control mechanism 62 adopts a water storage valve 621 with a time delay function to extend the drainage time of the drain valve outlet pipe 612.
In this embodiment, the control mechanism 62 comprises the water storage valve 621, the water storage valve inlet pipe 623, the water storage valve drain pipe 624, the inlet control valve 625, and the drain control valve 626.
The water storage valve 621 has the water storage cavity 6211, and the water storage valve inlet pipe 623 and water storage valve drain pipe 624 are in communication with the water storage cavity 6211 respectively. The inlet control valve 625 is mounted in the water storage valve inlet pipe 623 to control opening and closing of the water storage valve inlet pipe 623. The drain control valve 626 is mounted in the water storage valve drain pipe 624 for controlling opening and closing of the water storage valve drain pipe 624. The inlet control valve 625 and the drain control valve 626 are opened and closed alternately.
The water storage valve inlet pipe 623 is in communication with the drain valve pressure relief pipe 614, and the both may be connected directly or indirectly through piping.
If the inlet control valve 625 and drain control valve 626 are solenoid valves, they are controlled by the electric control mechanism in the control mechanism 62. If the inlet control valve 625 and the drain control valve 626 are mechanical valves, they are controlled by the mechanical mechanism in the control mechanism 62. When the first trigger end 620 is triggered, the electric control mechanism or mechanical mechanism in the control mechanism 62 acts to drive the inlet control valve 625 and the drain control valve 626 to open and close alternately.
When the control mechanism 62 is in the initial state, the inlet control valve 625 is in the closed state and the water storage valve inlet pipe 623 is closed, and thus the drain valve pressure relief pipe 614 does not drain, the drain valve diaphragm 613 is closed, and the drain valve outlet pipe 612 does not drain. At this time, the drain control valve 626 is in the opened state and the water storage valve drain pipe 624 drains the water in the storage cavity 6211 to a preset low water level, in preparing for the next water storage. The water drained from the water storage valve drain pipe 624 can flow into the seat base overflow pipe 14 through the pipe to clean the ceramic body.
When the control mechanism 62 is in the triggered state, the inlet control valve 625 is in the opened state, the water storage valve inlet pipe 623 is opened, and thus the drain valve pressure relief pipe 614 drains, the drain valve diaphragm 613 is opened, and the drain valve outlet pipe 612 drains. At this time, the drain control valve 626 is in the closed state to store water for the water storage cavity 6211. When water stored in the water storage cavity 6211 reaches the preset high water level, water no longer enters the water storage cavity 6211, the inlet control valve 625 is closed. In this process, the time taken by the water in the water storage cavity 6211 to rise 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 basically the drainage time of the drain valve outlet pipe 612. The delay time is determined by the volume of the water storage cavity 6211 and the water flow in the water storage valve inlet pipe 623.
The height, installation method and installation position of the water storage valve inlet pipe 623 and the water storage valve drain pipe 624 can be set according to actual needs. The drawings merely show one or two installation modes, which does not mean that such installation is inevitable.
In an embodiment, the water storage valve drain pipe 624 is in communication with a bottom of the water storage cavity 6211, and the water storage valve inlet pipe 623 is in communication with a top of the water storage cavity 6211.
In one of the embodiments, as shown in
The switching valve 622 comprises a switching valve housing 6220 having a channel 6221 and a switching shaft 6222 that is in clearance fit (e.g., engaged) with the channel 6221. The switching shaft 6222 is capable of alternately triggering the drain control valve 626 and the inlet control valve 625.
When the switching shaft 6222 is in an initial position, the switching shaft 6222 triggers the drain control valve 626, and the drain control valve 626 is in the opened state.
When the switching shaft 6222 is in a triggered position, the switching shaft 6222 triggers the inlet control valve 625, and the inlet control valve 625 is in the opened state.
In this embodiment, the switching valve 622 uses the switching shaft 6222 to alternately trigger the inlet control valve 625 and the drain control valve 626. The first trigger end 620 is configured at an upper end of the switching shaft 6222 of the switching valve 622, and the switching shaft 6222 is below the second trigger end 31. The first trigger end 620 may be an end cap or plate, or the first trigger end 620 may be the upper end portion of the switching shaft 6222 directly.
The switching valve 622 has a channel 6221 extending vertically, and the main body portion of the switching shaft 6222 is in clearance fit (e.g., engaged) with the channel 6221. The upper end of the switching shaft 6222 is above the switching valve housing 6220 and is used to be triggered by pressing.
In one of the assembly mode, the switching shaft 6222 and the first trigger end 620 can be triggered by the downward pressing of the second trigger end 31 of the pivot shaft 3 of the above-mentioned seat 2 that can move up and down.
In an alternative assembly mode, the switching shaft 6222 and first trigger end 620 may be connected to a handle, which is on the outside of the toilet, and the user may operate the handle to trigger the switching shaft 6222 and first trigger end 620 by pressing.
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 a press, 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 triggering or driving portion for triggering the inlet control valve 625 and the drain control valve 626, which may be a protrusion, recess or telescopic element, etc., provided on the switching shaft 6222.
The water storage valve inlet pipe 623 and the water storage valve drain pipe 624 are connected to the switching valve housing 6220 and in communication with the channel 6221, respectively. Therefore, when the switching shaft 6222 is moved to the corresponding position, the triggering/driving portion on the switching shaft 6222 can trigger the inlet control valve 625 or the drain control valve 626. When the inlet control valve 625 is triggered, the inlet control valve 625 opens the storage valve inlet pipe 623. When the drain control valve 626 is triggered, the drain control valve 626 opens the storage valve drain pipe 624.
In this case, when the switching shaft 6222 is in the initial position, at this time, the switching shaft 6222 triggers the drain control valve 626 to open, while the inlet control valve 625 is not triggered and remains closed, and the water storage cavity 6211 is in a draining state.
When the switching shaft 6222 is pressed to the triggered position, the switching shaft 6222 triggers the inlet control valve 625 to open, and the drain control valve 626 is not triggered and remains closed, and the water storage cavity 6211 is in a water storage state.
In this arrangement, the switching shaft 6222 controls the alternate opening and closing of the inlet control valve 625 and the drain control valve 626 to control the water storage and drainage functions of the water storage cavity 6211.
In one of the embodiments, as shown in
In one of the embodiments, as shown in
The drain control valve 626 comprises a second slide valve 6261 and a second reset member 6262 for driving the second slide valve 6261 to a closed state.
When the switching shaft 6222 is in the initial position, the first slide valve 6251 is in a closed state and the second slide valve 6261 is driven to open by the switching shaft 6222.
When the switching shaft 6222 is in the triggered position, the second slide valve 6261 is in a closed sate and the first slide valve 6251 is driven to open by the switching shaft 6222.
In this embodiment, both the inlet control valve 625 and the drain control valve 626 use a mechanical slide valve structure as follows.
As shown in
The first slide valve 6251 comprises a thicker first slide valve body 6251a and a first slide valve rod 6251b connected to the first slide valve body 6251a, the first slide valve rod 6251b extending toward and passable through the first through hole 6220a. A first step portion 6251c is formed at the connection between the first slide valve rod 6251b and the first slide valve body 6251a. The first step portion 6251c is in contact with and seals the first stop portion 6233 when the first slide valve 6251 is in the closed state, thereby closing the water storage valve inlet pipe 623.
The first reset member 6252 is connected to the first slide valve body 6251a for driving the first slide valve 6251 toward the side of the switching valve housing 6220 to enable the opened first slide valve 6251 to automatically reset to the closed position. The first reset member 6252 may be a spring.
As shown in
The second slide valve 6261 comprises a thicker second slide valve body 6261a and a second slide valve rod 6261b connected to the second slide valve body 6261a, the second slide valve rod 6261b extending toward and through the second through hole 6220b. A second step portion 6261c is formed at the connection of the second slide valve rod 6261b to the second slide valve body 6261a. The second step portion 6261c is in contact with and seals the second stop portion 6243 when the second slide valve 6261 is in the closed state, thereby closing the water storage valve drain 624.
The second reset member 6262 is connected to the second slide valve body 6261a for driving the second slide valve 6261 to move toward the side of the switching valve housing 6220 to enable the opened second slide valve 6261 to automatically reset to the closed position. The second reset member 6262 may be a spring.
When the switching valve 622 is in the initial position:
Under the action of the first reset member 6252, the first slide valve rod 6251b extends into the channel 6221 through the first through hole 6220a, the first step portion 6251c is in contact with the first stop portion 6233 and forms a seal therebetween, and the first slide valve 6251 closes the water storage valve inlet pipe 623 and will not supply water to the water storage cavity 6211.
The triggering/driving portion of the switching shaft 6222 cooperates and is in contact with the second slide valve rod 6261b of the second slide valve 6261 and overcomes the acting force of the second reset member 6262, pushing the second slide valve rod 6261b back from the channel 6221 so that the second step portion 6261c is separated from the second stop portion 6243, the water storage valve drain pipe 624 is opened, and the water storage cavity 6211 can be drained.
When the switching valve 622 is in the triggered position:
The triggering/driving portion of the switching shaft 6222 cooperates and is in contact with the first slide valve rod 6251b of the first slide valve 6251 and overcomes the acting force of the first reset member 6252, pushing the first slide valve rod 6251b backward from the channel 6221, so that the first step portion 6251c is separated from the first stop portion 6233, the water storage valve inlet pipe 623 is opened, and the water storage cavity 6211 can store water.
Under the action of the second reset member 6262, the second slide valve rod 6261b extends into the channel 6221 through the second through hole 6220b, the second step portion 6261c is in contact with the second stop portion 6243 and forms a seal therebetween, the second slide valve 6261 closes the water storage valve drain pipe 624, and the water storage cavity 6211 does not drain.

The first recess 6222a is for accommodating the end portion of the first slide valve 6251 and the second recess 6222b is for accommodating the end portion of the second slide valve 6261.
When the switching shaft 6222 in the initial position, the first recess 6222a is aligned with the first through hole 6220a and the end portion of the first slide valve 6251 (i.e., one end of the first slide valve rod 6251b) is inserted into the first recess 6222a through the first through hole 6220a. At this time, the first step portion 6251c is made to contact and seal the first stop portion 6233 under the action of the first reset member 6252, and the first slide 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 staggered from the second through hole 6220b, and the end portion of the second slide valve 6261 (i.e., one end of the second slide valve rod 6261b) leaves the second recess 6222b and contacts the circumferential surface or protrusion of the switching shaft 6222, thereby driving the second slide valve 6261 to compress the second reset member 6262 and causing the second step portion 6261c to separate from the second stop portion 6243, and the second slide valve 6261 to open, opening the water storage valve drain 624.

At this point, the second step portion 6261c is made to contact and seal the second stop portion 6243 under the action of the second reset member 6262, and the second slide valve 6261 closes the water storage valve drain 624.
In one of the embodiments, as shown in

The drain control valve 626 is in the first drain pipe 6241 or in the second drain pipe 6242.
In this embodiment, the second recess 6222b is used as a water cavity. The water storage valve drain pipe 624 comprises the first drain pipe 6241 and the second drain pipe 6242, and the switching valve housing 6220 is connected between the first drain pipe 6241 and the second drain pipe 6242. The first drain pipe 6241 is connected to the switching valve housing 6220, and the first drain pipe 6241 is in communication with the second recess 6222b. One end of the second drain pipe 6242 is in communication with the water storage cavity 6211, and the other end of the second drain pipe 6242 is in communication with the second recess 6222b.
When the drain control valve 626 is opened, water in the water storage cavity 6211 may be discharged through the second drain pipe 6242, the second recess 6222b, and the first drain pipe 6241. The first drain pipe 6241 may be in communication with the seat base overflow pipe 14 to drain water into the ceramic body for flushing.
The drain control valve 626 may be arranged in the first drain pipe 6241. In this structure, the water flow direction of the drained water is opposite to the acting direction of the second reset member 6262, and the second reset member 6262 is required to provide a larger resilient force to overcome the water pressure of the incoming water to avoid the second slide valve 6261 being opened by the water flow to ensure that the second slide valve 6261 can be closed.
In an embodiment, the drain control valve 626 is arranged in the second drain pipe 6242 as shown in
In one of the embodiments, the inlet control valve 625 is arranged in the first inlet pipe 6231, and the drain control valve 626 is arranged in the second drain pipe 6242, and the closing direction of the inlet control valve 625 and drain control valve 626 is the same as the direction of water flow at the corresponding place, which can reduce the force of the reset member and facilitate the sealing.

The water storage valve inlet pipe 623 and the water storage valve drain pipe 624 are in communication with the lower water storage cavity 6211a, respectively.
The lower water storage cavity 6211a has a floating valve 6214 for opening and closing the partition through hole 6213, and the upper water storage cavity 6211b is equipped with a water float 6215, and a connecting rod 6216 is connected between the floating valve 6214 and the water float 6215, and the connecting rod 6216 passes through the partition through hole 6213 with a clearance therebetween.
When water stored in the upper water storage cavity 6211b reaches a preset water level, the floating valve 6214 closes the partition through hole 6213.
In this embodiment, the water storage cavity 6211 is divided into the lower water storage cavity 6211a and the upper water storage cavity 6211b, with the partition 6212 having the partition through hole 6213 between them. The water storage valve inlet pipe 623 and water storage valve drain pipe 624 are connected to the lower water storage cavity 6211a, respectively.
The lower water storage cavity 6211a is equipped with the floating valve 6214 to automatically opening and closing the partition through hole 6213. The upper water storage cavity 6211b is equipped with the water float 6215, which is connected to the floating valve 6214 below through the connecting rod 6216 to drive the floating valve 6214 to move upward to seal the partition through hole 6213.
When water is stored and the water float 6215 rises a preset distance in the upper water storage cavity 6211b, the water float 6215 drives the floating valve 6214 to move upward to seal the partition through hole 6213, the pressure relief water in the drain valve pressure relief pipe 614 stops entering the water storage cavity 6211, the drain valve diaphragm 613 closes, and the drain valve drain pipe 612 automatically stops draining.
After the drain control valve 626 opens, the water in the lower water storage cavity 6211a is drained, the floating valve 6214 drops to open the partition through hole 6213, and the water float 6215 drops in the upper water storage cavity 6211b to prepare for the next water storage.

Embodiment 2:
The specific embodiments of the present disclosure should be further described with reference to the drawings hereinafter. Same and equivalent parts are denoted by same reference numerals. It should be noted that the terms “front”, “back”, “left”, “right”, “up” and “down” used in the following description refer to the directions in the drawings, and the terms “inner” and “outer” refer to the directions towards or far away from geometric centers of specific parts respectively.
As shown in
An adjustment hole 131 is provided on the left and right sides of a housing 13 (comprising e.g., a side plate) of the mounting base 1 respectively.
The pivot shaft 3 passes through the adjustment hole 131 and may be adjusted vertically in the adjustment hole 131.
A reset mechanism (e.g., an elastic member 32) for driving the pivot shaft 3 to move upward to reset is assembled between the mounting base 1 and the pivot shaft 3.
The present disclosure provides a seat assembly as a component in the seat and lid or cover plate of a toilet. The seat assembly comprises the mounting base 1, the seat 2, the pivot shaft 3 and the reset mechanism. The pivot shaft 3 is connected to a rear of the seat 2.
A long pivot shaft 3 may be provided at the rear of the seat 2, or a short pivot shaft 3 may be provided on the left and right sides of the rear of the seat 2 respectively, as required.
The housing 13 has adjustment holes 131 on the left and right sides of the mounting base 1, and the adjustment holes 131 may be bar-shaped holes or waist-shaped holes with the size in the height direction larger than the size in the forward and backward direction. The pivot shaft 3 passes through the adjustment hole 131 with a clearance therebetween and is adjustable by moving up and down in the adjustment hole 131. In an embodiment, the size of the adjustment hole 131 in the forward and backward direction is substantially equal to the diameter of the pivot shaft 3, which can avoid the pivot shaft 3 from wobbling forward and backward in the adjustment hole 131.
The reset mechanism is assembled between the pivot shaft 3 and the mounting base 1. When the seat 2 is not under pressure, the reset mechanism drives the pivot shaft 3 to move upward to a top of the adjustment hole 131 so that the rear of the seat 2 is in a higher position.
The reset mechanism may be a resilient reset mechanism or a piston reset mechanism, etc. The reset mechanism may be optionally mounted on the outside of the mounting base 1 or mounted in the mounting base 1.
In an embodiment, a resilient reset mechanism is selected as the reset mechanism, and the reset mechanism is mounted in the mounting base 1.
In an initial state, when the seat 2 is not under pressure from the user, the pivot shaft 3 is driven to move upward to the top of the adjustment hole 131 by the reset mechanism. At this time, the rear end of the seat 2 is in a higher position and will not contact the rear of the toilet body (ceramic body), and there is a certain distance between them to provide a cushion space.
When there is a user sitting on the seat 2, the seat 2 is under pressure and drives the pivot shaft 3 to move downward and overcome the acting force of the reset mechanism until the pivot shaft 3 reaches a bottom of the adjustment hole 131. At this time, the rear end of the seat 2 is in a lower position, and the rear end of the seat 2 is in contact with the rear of the toilet body (ceramic body). In the process, the reset mechanism provides a certain damping to slow down the descending of the rear end of the seat 2, thus providing a cushion effect and facilitating the user to gradually adapt to the hard contact between the seat 2 and the toilet body, thus enhancing the user experience.

Embodiment 4:
The specific embodiments of the present disclosure is further described with reference to the drawings hereinafter. Same and equivalent parts are denoted by same reference numerals. It should be noted that the terms “front”, “back”, “left”, “right”, “up” and “down” used in the following description refer to the directions in the drawings, and the terms “inner” and “outer” refer to the directions towards or far away from geometric centers of specific parts respectively.
As shown in
The drain valve 61 has a drain valve inlet pipe 613 for connecting with a hot water inlet end 16, a drain valve outlet pipe 612 for supplying hot water to the spray pipe 4.
The drain valve 61 has a drain valve diaphragm 613 for controlling opening and closing of the drain valve outlet pipe 612.
The drain valve outlet pipe 612 is connected to the spray pipe 4.
The pre-flush system also comprises a control mechanism 62 for controlling the opening and closing of the drain valve diaphragm 613.
When the control mechanism 62 is in an initial state, the drain valve diaphragm 613 is in a closed state.
When the control mechanism 62 is in a triggered state, the drain valve diaphragm 613 is in an opened state.
The present disclosure provides a pre-flush system for use in a toilet, which can be mounted in a mounting base at a rear of a seat device, and a base 11 (e.g., a base plate) of the mounting base has the hot water inlet end 16 and a base overflow pipe 14 (e.g., a seat base overflow pipe). The hot water inlet end 16 is connected to a hot water pipeline to provide hot water or warm water for the toilet. The hot water referred to in this present disclosure is the opposite concept of cold water, and the water temperature may be about 38° C., suitable for users to flush. The base overflow pipe 14 is used to drain excess water into the ceramic body of the toilet.
The pre-flush system comprises the spray pipe 4, the drain valve 3 and the control mechanism 62. The spray pipe 4 has a nozzle 41, and the spray pipe 4 can be mounted on the base 11 or on a front or side of the seat. The spray pipe 4 is retractable. When the user uses the spray pipe 4, the spray pipe 4 is extended; in the normal state, the spray pipe 4 is in a retracted state. The spray pipe 4 is connected to the water supply system of the toilet, and the water supply system can supply hot water or warm water to the spray pipe 4. The description of the spray pipe 4 is not repeated herein.
When the user uses the spray pipe 4, the hot water in the spray pipe 4 may be cooled down to cold water, and the direct spraying will affect the user experience.
The present disclosure uses drain valve 3 and control mechanism 62 to provide a pre-flush function for spray pipe 4 to flush out the cold water (e.g., water residual) in the spray pipe 4 with hot water and fill the spray pipe 4 with hot water, before the user uses the spray pipe 4. When the user uses it, the nozzle 41 directly sprays hot water.
The drain valve 61 is mounted on the base 11.
The drain valve 61 has a drain valve inlet pipe 611 and a drain valve outlet pipe 612 connected to it, and the drain valve 61 has a drain valve diaphragm 613. The drain valve outlet pipe 612 is connected to an inlet end 21 on the spray pipe 4 through a water pipe for supplying hot water to the spray pipe 4. The drain valve diaphragm 613 can control opening and closing of the drain valve outlet pipe 612 in order to control the water supply from the drain valve outlet pipe 612 to the spray pipe 4.
The control mechanism 62 may be an electric control mechanism or a mechanical mechanism. The control mechanism 62 may be triggered to act to control opening and closing of the drain valve diaphragm 613, which in turn controls opening and closing of the drain valve outlet pipe 612. The control mechanism 62 may directly control the drain valve diaphragm 613 to act or indirectly control the drain valve diaphragm 613 to act. If the control mechanism 62 is an electric control mechanism or mechanical mechanism, a connecting rod is mounted on an output end of the electric control mechanism or mechanical mechanism, the drain valve diaphragm 613 is sleeved on the connecting rod, and the connecting rod drives the drain valve diaphragm 613 to act. The control mechanism 62 can also drive the drain valve diaphragm 613 to act by water pressure.
When the control mechanism 62 is in the initial state, the drain valve diaphragm 613 is in the closed state and the drain valve outlet pipe 612 is closed.
When the control mechanism 62 is in the triggered state, the drain valve diaphragm 613 is in the opened state and the drain valve outlet pipe 612 supplies hot water to the spray pipe 4 to flush out the cold water from the spray pipe 4.
When the user uses the toilet, the spray pipe 4 is in the retracted state before the spray pipe 4 is used. When the user triggers the control mechanism 62, the drain valve outlet pipe 612 supplies hot water to the spray pipe 4, and the hot water fills the spray pipe 4 to flush out the cold water in the spray pipe 4. The water in the spray pipe 4 can be drained out through the nozzle 41 and flow into the ceramic body. Because the water pressure of the drain valve outlet pipe 612 will not be too high, the water in the spray pipe 4 flows out slowly through the nozzle 41 instead of being sprayed out.
Thus, according to the pre-flush system provided by the present disclosure, when using the toilet, the user can trigger the control mechanism 62 as needed before flushing with the spray pipe 4, the warm water in the drain valve 61 flows into the spray pipe 4 to pre-flush out the cold water in the spray pipe 4, the cold water flushed out can be drained into the ceramic cylinder of the toilet and can play a role of cleaning, and when the user uses the spray pipe 4 later, the water sprayed from the spray pipe 4 is basically warm water, which enhancing the user experience.
In one of the embodiments, as shown in
When the control mechanism 62 is in the initial state, the drain valve pressure relief pipe 614 is in a stopping drainage state.
When the control mechanism 62 is in the triggered state, the drain valve pressure relief pipe 614 is in a draining state.
In this embodiment, the water pressure is used to control the drain valve diaphragm 613 to open and close.
The drain valve 61 has an upper water cavity 615 and a lower water cavity 616. The drain valve outlet pipe 612 is mounted on the top of the drain valve 61, and an inlet of drain valve outlet pipe 612 has a circle of baffle rib 617 extending downward. The drain valve diaphragm 613 is in the upper water cavity 615 and lower water cavity 616, and drain valve diaphragm 613 has a communication hole 6131.
When the drain valve pressure relief pipe 614 does not drain outward, the water in the upper water cavity 615 enters the lower water cavity 616, gradually making the water pressure in the upper water cavity 615 and the water pressure in the lower water cavity 616 balance, such that the drain valve diaphragm 613 seals the baffle rib 617, and the drain valve outlet pipe 612 does not drain.
When the drain valve pressure relief pipe 614 drains outward, the water pressure in the lower water cavity 616 decreases, the drain valve diaphragm 613 leaves the baffle rib 617 downward, and the drain valve outlet pipe 612 drains.
The control mechanism 62 is used to control the drain valve pressure relief pipe 614 to drain or stop draining, and the control mechanism 62 may be a valve structure connected to the drain valve pressure relief pipe 614.
When the control mechanism 62 is in the initial state, the drain valve pressure relief pipe 614 does not drain and the drain valve outlet pipe 612 does not drain.
When the control mechanism 62 is in the triggered state, the drain valve pressure relief pipe 614 drains and the drain valve outlet pipe 612 drains.
The water drained from the drain valve pressure relief pipe 614 can flow into the base overflow pipe 14 through the pipe to clean the ceramic body.
In one of the embodiments, as shown in
The water storage valve 621 is connected to a water storage valve inlet pipe 623 and a water storage valve drain pipe 624 that are in communication with the water storage cavity 6211, with an inlet control valve 625 provided in the water storage valve inlet pipe 623 and a drain control valve 626 provided in the water storage valve drain pipe 624.
The water storage valve inlet pipe 623 is in communication with the drain valve pressure relief pipe 614.
When the control mechanism 62 is in the initial state, the inlet control valve 625 is in a closed state and the drain control valve 626 is in an opened state.
When the control mechanism 62 is in the triggered state, the inlet control valve 625 is in an opened state and the drain control valve 626 is in a closed state.
In this embodiment, the control mechanism 62 uses a water storage valve 621 with a time delay function to extend the drainage time of the drain valve outlet pipe 612.
In this embodiment, the control mechanism 62 comprises the water storage valve 621, the water storage valve inlet pipe 623, the water storage valve drain pipe 624, the inlet control valve 625 and the drain control valve 626.
The water storage valve 621 has the water storage cavity 6211, and the water storage valve inlet pipe 623 and the water storage valve drain pipe 624 are in communication with the water storage cavity 6211, respectively. The inlet control valve 625 is mounted in the water storage valve inlet pipe 623 to control opening and closing of the water storage valve inlet pipe 623. The drain control valve 626 is mounted in the water storage valve drain pipe 624 to control the opening and closing of the water storage valve drain pipe 624. The inlet control valve 625 and the drain control valve 626 are opened and closed alternately.
The water storage valve inlet pipe 623 is in communication with the drain valve pressure relief pipe 614, and the two can be directly connected or indirectly connected through the pipe.
If the inlet control valve 625 and drain control valve 626 are electromagnetic valves, they are controlled by the electric control mechanism in the control mechanism 62. If the inlet control valve 625 and drain control valve 626 are mechanical valves, they are controlled by the mechanical mechanism in the control mechanism 62.
When the control mechanism 62 is in the initial state, the inlet control valve 625 is in the closed state, the water storage valve inlet pipe 623 is closed, then the drain valve pressure relief pipe 614 does not drain, the drain valve diaphragm 613 is closed, and the drain valve outlet pipe 612 does not drain. At this time, the drain control valve 626 is in the opened state and the water storage valve drain pipe 624 drains the water in the water storage cavity 6211 to the preset low water level, preparing for the next water storage. The water storage valve drain pipe 624 is in communication with the base overflow pipe 14, and the water drained from the water storage valve drain pipe 624 can flow into the base overflow pipe 14 through the pipe to clean the ceramic body.
When the control mechanism 62 is in the triggered state, the inlet control valve 625 is in the opened state, the water storage valve inlet pipe 623 is opened, then the drain valve pressure relief pipe 614 drains, the drain valve diaphragm 613 is opened, and the drain valve outlet pipe 612 drains. At this time, the drain control valve 626 is in the closed state to store water for the water storage cavity 6211. When water stored in the water storage cavity 6211 reaches the preset high water level, water no longer enters the water storage cavity 6211, and the inlet control valve 625 is closed. In this process, the time taken by the water in the water storage cavity 6211 to rise 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 basically the drainage time of the drain valve outlet pipe 612. The delay time is determined by the volume of the water storage cavity 6211 and the water flow in the water storage valve inlet pipe 623.
The height, installation method and installation position of the water storage valve inlet pipe 623 and the water storage valve drain pipe 624 can be set according to actual needs, and only one or two installation modes are shown in the attached drawings, which does not mean that such installation is inevitable.
In an embodiment, the water storage valve drain pipe 624 is in communication with a bottom of the water storage cavity 6211, and the water storage valve inlet pipe 623 is in communication with a top of the water storage cavity 6211.
In one of the embodiments, as shown in
The switching valve 622 comprises a switching valve housing 6220 having a channel 6221 and a switching shaft 6222 that is in clearance fit (e.g., engaged) with the channel 6221.

The water storage valve inlet pipe 623 and the water storage valve drain pipe 624 are each connected to the switching valve housing 6220 and in communication with the channel 6221. Therefore, when the switching shaft 6222 is moved to the corresponding position, the triggering/driving portion on the switching shaft 6222 can trigger the inlet control valve 625 or the drain control valve 626. When the inlet control valve 625 is triggered, the inlet control valve 625 opens the water storage valve inlet pipe 623. When the drain control valve 626 is triggered, the drain control valve 626 opens the water storage valve drain pipe 624.
In this case, when the switching shaft 6222 is in the initial position, the switching shaft 6222 triggers the drain control valve 626 to open, and the inlet control valve 625 is not triggered and therefore remains closed, and the water storage cavity 6211 is in the draining state.
When the switching shaft 6222 is pressed to the triggered position, the switching shaft 6222 triggers the inlet control valve 625 to open, and the inlet control valve 625 is not triggered and therefore remains closed, and the water storage cavity 6211 is in the water storage state.
In this arrangement, the switching shaft 6222 controls the alternate opening and closing of the inlet control valve 625 and the drain control valve 626 to control the water storage and drainage functions of the water storage cavity 6211.
In one of the embodiments, a switching shaft reset member 6223 for driving the switching shaft 6222 to reset to the initial position is connected between the switching valve housing 6220 and the switching shaft 6222 as shown in
In one of the embodiments, as shown in
The drain control valve 626 comprises a second slide valve 6261 and a second reset member 6262 for driving the second slide valve 6261 to reset to a closed state.
When the switching shaft 6222 in the initial position, the first slide valve 6251 is in the closed state and the second slide valve 6261 is driven to open by the switching shaft 6222.
When the switching shaft 6222 is in the triggered position, the second slide valve 6261 is in the closed state and the first slide valve 6251 is driven to open by the switching shaft 6222.
In this embodiment, both the inlet control valve 625 and the drain control valve 626 adopt a mechanical slide valve structure as follows:
As shown in
The first slide valve 6251 comprises a thicker first slide valve body 6251a and a first slide valve rod 6251b connected to the first slide valve body 6251a, the first slide valve rod 6251b extending toward and through the first through hole 6220a. A first step portion 6251c is formed at the connection of the first slide valve rod 6251b and the first slide valve body 6251a. When the first slide valve 6251 is in the closed sate, the first step 6251c is in contact with and seals the first stop 6233, thereby closing the water storage valve inlet pipe 623.
The first reset member 6252 is connected to the first slide valve body 6251a for driving the first slide valve 6251 toward the side of the switching valve housing 6220 to enable the opened first slide valve 6251 to automatically reset to the closed position. The first reset member 6252 may be a spring.
As shown in
The second slide valve 6261 comprises a thicker second slide valve body 6261a and a second slide valve rod 6261b connected to the second slide valve body 6261a, the second slide valve rod 6261b extending toward and through the second through hole 6220b. A second step portion 6261c is formed at the connection of the second slide valve rod 6261b and the second slide valve body 6261a. When the second slide valve 451 is in the closed state, the second step portion 6261c is in contact with and seals the second stop portion 6243, thereby closing the water storage valve drain pipe 624.
The second reset member 6262 is connected to the second slide valve body 6261a for driving the second slide valve 6261 toward the side of the switching valve housing 6220 to enable the opened second slide valve 6261 to automatically reset to the closed position. The second reset member 6262 may be a spring.
When the switching valve 622 is in the initial position:
Under the action of the first reset member 6252, the first slide valve rod 6251b extends into the channel 6221 through the first through hole 6220a, the first step portion 6251c is in contact with the first stop portion 6233 and forms a seal therebetween, and the first slide valve 6251 closes the water storage valve inlet pipe 623 and will not supply water to the water storage cavity 411.
The triggering/driving portion of the switching shaft 6222 contacts and cooperates with the second slide valve rod 6261b of the second slide valve 6261 and overcomes the acting force of the second reset member 6262 to push the second slide valve rod 6261b backward from the channel 6221 so that the second step portion 6261c is separated from the second stop portion 6243, the water storage valve drain pipe 624 is opened, and the water storage cavity 411 can be drained.
When the switching valve 622 is in the triggered position:
The triggering/driving portion of the switching shaft 6222 contacts and cooperates with the first slide valve rod 6251b of the first slide valve 6251, and overcomes the acting force of the first reset member 6252 to push the first slide valve rod 6251b backward from the channel 6221, so that the first step portion 6251c is separated from the first stop portion 6233, the water storage valve inlet pipe 623 is opened, and the water storage cavity 6251 can store water.
Under the action of the second reset member 6262, the second slide valve rod 6261b extends into the channel 6221 through the second through hole 6220b, the second step portion 6261c contacts and seals the second stop portion 6243, the second slide valve 6261 closes the water storage valve drain pipe 624, and the water storage cavity 411 does not drain.
In one of the embodiments, as shown in
When the switching shaft 6222 is in the initial position, one end of the first slide valve 6251 is in the first recess 6222a and one end of the second slide valve 6261 is in contact with a circumferential surface of the switching shaft 6222.
When the switching shaft 6222 is in the triggered position, one end of the second slide valve 6261 is in the second recess 6222b and one end of the first slide valve 6251 is in contact with the circumferential surface of the switching shaft 6222.

The first recess 6222a is for accommodating the end portion of the first slide valve 6251 and the second recess 6222b is for accommodating the end portion of the second slide valve 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 portion of the first slide valve 6251 (i.e., one end of the first slide valve rod 6251b) is inserted into the first recess 6222a through the first through hole 6220a. At this time, the first step portion 6251c is made to contact and seal the first stop portion 6233 under the action of the first reset member 6252, and the first slide 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 staggered from the second through hole 6220b, the end portion of the second slide valve 6261 (i.e., one end of the second slide valve rod 6261b) leaves the second recess 6222b and contacts the circumferential surface or the protrusion of the switching shaft 6222, thereby driving the second slide valve 6261 to compress the second reset member 6262 and causing the second step portion 6261c to separate from the second stop portion 6243, and the second slide valve 6261 to opens, opening the water storage valve drain pipe 624.
When the switching shaft 6222 is in the triggered state, the first recess 6222a is staggered from the first through hole 6220a, and the end portion of the first slide valve 6251 (i.e., one end of the first slide valve rod 6251b) leaves the first recess 6222a and contacts the circumferential surface or protrusion of the switching shaft 6222, thereby driving the first slide valve 6251 to compress the first reset member 6252 and causing the first step portion 6251c to separate from the first stop portion 6233, and the first slide valve 6251 to open, opening the water storage valve inlet pipe 623.
When the switching shaft 6222 is in the triggered state, the second recess 6222b is aligned with the second through hole 6220b and the end portion of the second slide valve 6261 (i.e., one end of the second slide valve rod 6261b) is inserted into the second recess 6222b through the second through hole 6220b. At this time, the second step portion 6261c is made to contact and seal the second stop portion 6243 under the action of the second reset member 6262, and the second slide valve 6261 closes the water storage valve drain pipe 624.
In one of the embodiments, as shown in
The first inlet pipe 6231 communicates the drain valve pressure relief pipe 614 to the first recess 6222a, and the second inlet pipe 6232 communicates the water storage cavity 411 to the first recess 6222a.
The inlet control valve 625 is in the first inlet pipe 6231 or in the second inlet pipe 6232.
In this embodiment, the first recess 6222a is used as a water cavity. The water storage valve inlet pipe 42 comprises the first inlet pipe 6231 and the second inlet pipe 6232, and the switching valve housing 6220 is connected between the first inlet pipe 6231 and the second inlet pipe 6232. The first inlet pipe 6231 is in communication with the drain valve pressure relief pipe 614, and the first inlet pipe 6231 is also in communication with the first recess 6222a. One end of the second inlet pipe 6232 is in communication with the water storage cavity 6211, and the other end of the second inlet pipe 6232 is in communication with the first recess 6222a.
When the inlet control valve 625 is opened, water in the drain valve pressure relief pipe 614 can enter the water storage cavity 411 through the first inlet pipe 6231, the first recess 6222a and the second inlet pipe 6232.
As shown in
In an embodiment, the inlet control valve 625 is arranged in the first inlet pipe 6231 as shown in
In one of the embodiments, as shown in
The first drain 6241 is connected to the switching valve housing 6220 and in communication with the second recess 6222b, and the second drain pipe 6242 communicates the water storage cavity 411 to the second recess 6222b.
The drain control valve 626 is in the first drain pipe 6241 or in the second drain pipe 6242.
In this embodiment, the second recess 6222b is used as a water cavity. The water storage valve drain pipe 624 comprises the first drain pipe 6241 and the second drain pipe 6242, and the switching valve housing 6220 is connected between the first drain pipe 6241 and the second drain pipe 6242. The first drain pipe 6241 is connected to the switching valve housing 6220, and the first drain pipe 6241 is in communication with the second recess 6222b. One end of the second drain pipe 6242 is in communication with the water storage cavity 411 and its other end is in communication with the second recess 6222b.
When the drain control valve 626 is opened, water in the water storage cavity 411 can be drained through the second drain pipe 6242, the second recess 6222b, and the first drain pipe 6241. The first drain pipe 6241 may be in communication with the base overflow pipe 14 to drain water into the ceramic body for flushing.
The drain control valve 626 may be arranged in the first drain pipe 6241. In this structure, the water flow direction of the drained water is opposite to the acting direction of the second reset member 6262, and the second reset member 6262 is required to provide a larger elastic force to overcome the water pressure of the incoming water to avoid the second slide valve 6261 being opened by the water flow to ensure that the second slide valve 6261 can be closed.
In an embodiment, as shown in
In one of the embodiments, the inlet control valve 625 is arranged in the first inlet pipe 6231 and the drain control valve 626 is arranged in the second drain pipe 6242, and the closing direction of the inlet control valve 625 and the drain control valve 626 is in the same direction as the water flow at the corresponding place, which can reduce the force of the reset member and facilitate the sealing.
In one of the embodiments, as shown in
In one of the embodiments, as shown in
When water stored in the water storage cavity 6211 reaches a preset water level, the floating valve 6214 closes the water storage cavity drainage hole 6213.
In this embodiment, the water storage cavity drainage hole 6213 is automatically opened and closed by providing the floating valve 6214 in the water storage cavity 411. When the water stored in the water storage cavity 6211 reaches a preset water level (high water level), the floating valve 6124 floats up and closes the water storage cavity drainage hole 6213, the pressure relief water in the drain valve pressure relief pipe 614 stops entering the water storage cavity 6211, the drain valve diaphragm 613 is closed, and the drain valve outlet pipe 612 automatically stops draining.
After the drain control valve 626 is opened, the water in the water storage cavity 411 is drained, and the floating valve 6214 drops to open the water storage cavity drainage hole 6213.
In one of the embodiments, as shown in
A connecting rod 6216 is connected between the floating valve 6214 and the water float 6215, and the connecting rod 6216 passes through the water storage cavity drainage hole 6213 with a clearance therebetween.
In this embodiment, the water tank 414 is arranged above the water storage cavity 411 for configuring the water float 6215. The water float 6215 has a large volume and buoyancy. The water float 6215 is connected to the floating valve 6214 below through the connecting rod 6216, which helps drive the floating valve 6214 to move upward to seal the water storage cavity drainage hole 6213.
In this embodiment, the water in the water storage cavity 411 is always full, the water level changes in the water tank 414.
When the water float 6215 rises to a preset distance in the water tank 414, the water float 6215 drives the floating valve 6214 to move upward to seal the water storage cavity drainage hole 6213.
In one of the embodiments, as shown in
An embodiment of the present disclosure provides a toilet comprising a pre-flush system according to any of the embodiments above. The pre-flush system may be mounted in the seat device of the toilet.
The above technical solutions may be combined as required to achieve the best technical effect.
Embodiment 5:
At act S101, the control mechanism 62 of the seat device maintains the drain valve diaphragm 613 in the closed state when the control mechanism 62 is not triggered.
Specifically, as noted above, the rest mechanism maintains the first trigger end 620 of the control mechanism 62 spaced apart from the second trigger end 31 of the pivot shaft 3. In an initial state, that is, when the seat 2 is not under pressure from the user, the pivot shaft 3 is driven to move upwardly to the top of the adjustment hole 131 by the reset mechanism 32. At this time, a rear end of the seat 2 is in a higher position, and the rear end of the seat 2 does not contact the rear of the toilet body 7 (ceramic body), and there is a certain distance between them to provide a cushion space.
The control mechanism 62 controls the drain valve pressure relief pipe 614 to stop discharging water into the toilet body 7 so as to generate the balanced pressure in the drain valve 61. The drain valve diaphragm 613 seals the baffle rib 617 in the drain valve 61 in response to the balanced pressure. When the drain valve pressure relief pipe 614 does not drain outward, the water in the upper water cavity 615 enters the lower water cavity 616, gradually making the water pressure in the upper water cavity 615 and the water pressure in the lower water cavity 616 balance, such that the drain valve diaphragm 613 seals the baffle rib 617, and the drain valve outlet pipe 612 does not drain.
At act S102, the control mechanism 62 is triggered to open the drain valve diaphragm 613, in response to the pressure on the seat 2 of the seat device generated by the user.
Specifically, as noted above, the pivot shaft 3 is moved downwards until the second trigger end 31 of the pivot shaft 3 contacts the first trigger end 620 of the control mechanism 62 to trigger the control mechanism 62, in response to the pressure on the seat 2 of the seat device generated by the user. When there is a user sitting on the seat 2, the seat 2 is under pressure and drives the pivot shaft 3 to move downward against the acting force of the reset mechanism 32 until the pivot shaft 3 reaches a bottom of the adjustment hole 131. At this time, the rear end of the seat 2 is in a lower position, and the rear end of the seat 2 is in contact with the rear of the toilet body 7 (ceramic body). The second trigger end 31 is lowered to the lowest position/descending position, and the second trigger end 31 triggers the first trigger end 620.
The control mechanism 62 controls the drain valve pressure relief pipe 614 to discharge the water into the toilet body 7 so as to generate an unbalanced pressure in the drain valve 61. The drain valve diaphragm unseals the baffle rib 617 in the drain valve 61 in response to the unbalanced pressure. When the drain valve pressure relief pipe 614 drains outward, the water pressure in the lower water cavity 616 decreases, the drain valve diaphragm 613 leaves the baffle rib 617 downward, and the drain valve outlet pipe 612 drains.
At act S103, the hot water is discharged from the hot water inlet end 16 of the seat device into the spray pipe 4 to flush the water residual out of the spray pipe 4 when the drain valve diaphragm 613 is opened.
Specifically, as noted above, the pre-flush system 6 uses the drain valve 61 and control mechanism 62 to achieve the pre-flush function of the spray pipe 4, flushing out the cold water in the spray pipe 4 through the hot water before the user uses the spray pipe 4 and filling the spray pipe 4 with hot water. When the user uses it, the nozzle 41 directly emits hot water. When the control mechanism 62 is in the triggered state, the drain valve diaphragm 613 is in the opened state and the drain valve outlet pipe 612 supplies hot water to the spray pipe 4 to flush the cold water out of the spray pipe 4.
The above are merely the principle and the embodiments of the present disclosure. It should be pointed out that, for those having ordinary skill in the art, several other modifications may be made on the basis of the principle of the present disclosure, which should also be regarded as falling in the protection scope of the present disclosure.
