The technical solution provided by the embodiments of the present invention is described below with reference to the accompanying drawings.

The utility model provides a sanitary ware equipment 100.

In one embodiment, the sanitary fixture 100 is a toilet, it being understood that the sanitary fixture 100 may also be other fixtures that require flushing, such as a sink, a bathtub, etc.

Specifically, referring to fig. 1, the sanitary equipment 100 includes a drainage device 20 and a body 30 connected to the drainage device 20, the body 30 is provided with a liquid pool 31, and a drain outlet 311 is formed at the bottom of the liquid pool 31. As shown in fig. 2A and 3, drain 20 includes a flush mechanism 40, and a regulating assembly 50 connected to flush mechanism 40. The control assembly 50 is used to control the flushing mechanism 40 so that the fluid in the flushing mechanism 40 can perform a washing or flushing operation on the body 30. The body 30 may have a washing waterway 32 to guide the fluid in the drain device 20 to the upper side of the liquid pool 31, so that the fluid can uniformly wash the inner wall of the liquid pool 31 from top to bottom. The body 30 may further include a spray water path 33 and a siphon 34 connected to the waste discharge opening 311, wherein the spray water path 33 guides the fluid in the drainage device 20 to the liquid pool 31 and discharges the dirt in the liquid pool 31 through the waste discharge opening 311 and the siphon 34.

The utility model provides a bath mechanism 40.

Specifically, referring to fig. 2A and 3, the flushing mechanism 40 includes: the flush mechanism 40 includes: a driving assembly 41, a driven assembly 42 and a transmission assembly 43. The driving assembly 41 has a plurality of driving chambers 411 for accommodating fluid and having a variable size. The driven assembly 42 has a driven chamber 421 of variable size for receiving a fluid. When the driving chamber 411 is expanded by the driving external force, the driving assembly 41 is transmitted through the transmission assembly 43 to press the driven chamber 421, so that the fluid in the driven chamber 421 is discharged.

The basic principle of application of the flush mechanism 40 is as follows:

by injecting the fluid into the slave chamber 421 in advance, the internal space of the slave chamber 421 is sufficiently expanded, and the drive chamber 411 is evacuated in advance, so that the drive chamber 411 is in a contracted state. When the fluid supply source 700 generating the driving external force injects the fluid into the driving chamber 411 in the contracted state, the driving chamber 411 is filled with the fluid to expand its space. The driving chamber 411 transmits a driving external force to the transmission assembly 43 when expanding, and the driven chamber 421 is compressed by the transmission action of the transmission assembly 43, so that the fluid stored in the driven chamber 421 is discharged to the body 30 of the sanitary ware 100. Since the sum of the amount of spatial variation of the driven chamber 421 is greater than the amount of spatial variation of the driving chamber 411 when the driving chamber 411 is expanded, the amount of fluid discharged from the driven chamber 421 is greater than the amount of fluid entering the driving chamber 411.

In the drainage process, the flushing flow to the body 30 can be ensured by using the fluid pressure borne by the driven chamber 421, so that the flushing mechanism 40 does not need to be placed at a certain height, and the optimization of the appearance design or the internal structure layout of the sanitary ware 100 is facilitated.

The fluid supply 700 has various forms.

Specifically, in some embodiments, the fluid supply 700 is the output of a municipal tap water line, and the fluid injected into the drive 411 or driven 421 chambers is tap water. In other embodiments, the fluid supply source 700 may be an output of a municipal tap water pipeline through a pressure pump, or a pumping output of an external pump of the sanitary fixture 100 to an external water storage.

The regulation assembly 50 is used to realize the regulation of the fluid in and out of the driving chamber 411 and the driven chamber 421.

In some embodiments, the regulating assembly 50 is used to control the on/off between the fluid supply 700 and the driving chamber 411, and the fluid provided by the fluid supply 700 is input to the driving chamber 411. The fluid input to the driving chamber 411 generates a driving external force to the driving chamber 411 to expand the driving chamber 411 and compress the driven chamber 421. After the compression of the driven chamber 421 is completed, the regulating assembly 50 is used for guiding and supplementing the fluid in the driving chamber 411 to the driven chamber 421, and is also used for controlling the on-off between the driven chamber 421 and the fluid supply source 700, and supplementing the fluid provided by the fluid supply source 700 to the driven chamber 421.

Referring again to fig. 2A and 3, the regulating assembly 50 includes a primary side switching valve 51, a switch control 52 and a water tank 53. The main-side switching valve element 51 is connected between the fluid supply source 700 and the driving chamber 411, and the main-side switching valve element 51 is also connected between the driving chamber 411 and the water tank 53. The switch control 52 is connected between the main-side switching valve element 51 and the fluid supply source 700. The switch control 52 is a valve structure, more specifically, a solenoid-operated valve. The liquid level control member 531 controls the liquid level of the fluid in the tank 53 to be 535 by adjusting the on/off state of the liquid inlet valve 532, and the liquid level control member 532 controls the liquid level of the fluid in the tank 53 to be 535. The inner cavity of the water tank 53 is connected to the driven chamber 421 through a fluid supplementing pipe 533, and a check valve 534 is disposed on the fluid supplementing pipe 533 to prevent the fluid in the driven chamber 421 from flowing back to the water tank 53, but to allow the fluid in the water tank 53 to flow to the driven chamber 421 through the check valve 534. The slave chamber 421 is positioned below a predetermined level 535.

The driven chamber 421 communicates with the body 30 through a drain pipe 60.

Specifically, the drain device 20 further includes a drain pipe 60 communicating with the driven chamber 421, and the drain pipe 60 leads to the liquid pool 31 to guide the fluid discharged from the driven chamber 421 to flow to the liquid pool 31. The drain 60 also serves to restrict fluid to the slave chamber 421 before draining of the slave chamber 421 is initiated.

Referring again to fig. 2A and 3, in this embodiment, the drain 60 is at least partially higher than the driven chamber 421, which is partially the high section 62 of the drain 60. Further, the slave chamber 421 is connected to the drain pipe 60 by a transition 4211, and the level of the transition 4211 is higher than the body of the slave chamber 421 and slightly lower than the high section 62 of the drain pipe 60. In the embodiment shown in fig. 2A and 3, the driven chamber 421 communicates from its top side to a transition 4211. Further, the drain 20 further includes a siphon relief valve 61 connected to the drain pipe 60, the siphon relief valve 61 being connected to a portion of the drain pipe 60 above the predetermined liquid level 535.

The basic operating principle of the drain 20 is as follows:

when the fluid starts to be injected into the driving chamber 411, the drainage process of the driven chamber 421 is started.

Specifically, referring to fig. 2A and 3, when the switch control member 52 receives a drainage command, the switch control member 52 is controlled to be turned on, the fluid provided by the fluid supply source 700 passes through the switch control member 52, and the hydraulic pressure of the fluid acts on the primary side switching valve member 51, so that the primary side switching valve member 51 of the three-way structure is switched to open the flow passage between the fluid supply source 700 and the driving cavity 411 and close the flow passage between the driving cavity 411 and the water tank 53. The injection of fluid tends to expand the driving chamber 411, the driving chamber 411 acts on the driven chamber 421 through the transmission assembly 43 to squeeze the driven chamber 421, and the liquid level in the driven chamber 421 rises due to the compression of the driven chamber 421.

Before the fluid level in the slave chamber 421 and the drain 60 rises above the high level section 62 of the drain 60, fluid is confined in the slave chamber 421 or the transition 4211 to avoid the fluid in the slave chamber 421 from spontaneously flowing around the drain 60 under its own weight. After the driven chamber 421 is sufficiently compressed, the liquid level in the driven chamber 421 and the drain pipe 60 rises and passes over the high-level section 62 of the drain pipe 60, and the fluid is discharged from the drain pipe 60, flows out into the body 30, and outputs a large volume of fluid to the body 30.

Further, the drain 60 is partially positioned above the predetermined level 535. In other words, the highest portion of the drain pipe 60 is disposed higher than the main structure of the tank 53. Unlike the conventional water tank 53 that must be set at a high position to generate potential energy to drain the water to the drain pipe 60, the water tank 53 is set at a position that is more flexible and can reduce the overall volume of the drain device 20 or the sanitary ware 100, thereby improving the layout.

When the drain pipe 60 discharges the stored water by compressing the driven chamber 421, the siphon release valve 61 isolates the inside and outside air pressure environments of the drain pipe 60 by the high pressure of the stored water, thereby preventing the stored water discharged from the drain pipe 60 from leaking through the siphon release valve 61. The fluid in the driven chamber 421 cannot flow backward to the tank 53 when the water is discharged, restricted by the check valve 534.

The stored water in the driven chamber 421 can be sufficiently discharged for a predetermined time.

After the drain command is cancelled for the predetermined time, referring to fig. 2A and fig. 3 again, the switch control member 52 connected between the main-side switching valve member 51 and the fluid supply source 700 is controlled to switch to the off state, the main-side switching valve member 51 loses the pressure effect of the fluid, and the internal flow passage of the main-side switching valve member 51 of the three-way structure is thus switched to the state of communicating the driving chamber 411 with the water tank 53 and isolating the fluid supply source 700 from the driving chamber 411. The driving chamber 411 completes the compression of the driven chamber 421 due to the loss of the driving external force provided by the fluid, and the accumulated water in the driving chamber 411 is guided to be supplemented to the water tank 53 in the subsequent water supplementing process of the driven chamber 421.

If the switching control member 52 is unexpectedly turned off or the fluid supply source 700 itself stops outputting before the stored water in the slave chamber 421 is sufficiently discharged, the driving chamber 411 stops expanding due to the loss of the driving external force provided by the fluid, and the compression of the slave chamber 421 is interrupted. Specifically, the cessation of output from the fluid supply 700 may be due to a loss of water from a municipal water line or a valve associated with the fluid supply 700 that stops the fluid output from the fluid supply 700.

After the compression of the driven chamber 421 is completed or interrupted, the stored water being discharged from the drain pipe 60 forms a negative pressure inside the drain pipe 60 due to the loss of the force compressing the driven chamber 421. The siphon release valve 61 communicates the inside and outside air pressure environments of the drain pipe 60 under the negative pressure, and the air flow outside the drain pipe 60 enters the inside of the drain pipe 60 to release the negative pressure in the drain pipe 60, thereby interrupting the water flow in the drain pipe 60 and preventing the stored water discharged from the drain pipe 60 from continuously sucking fluid from the water tank 53, the fluid replenishing pipe 533 and the driven chamber 421 in sequence into the drain pipe 60 under the negative pressure.

Referring again to fig. 2A and 3, after compression of the slave chamber 421 is completed or interrupted, the weight of the remaining water in the slave chamber 421 creates a pressure against the inner wall of the slave chamber 421. The slave chamber 421 expands and deforms under this pressure, causing the fluid level in the slave chamber 421 or the drain 60 to drop below the predetermined level 535 without fluid replenishment. Since the placement height of the driven chamber 421 is lower than the predetermined level 535 and the water tank 53 is connected to the driven chamber 421 through the fluid-replenishing pipe 533, when the fluid level in the driven chamber 421 or the drain pipe 60 is lower than the predetermined level 535, the fluid in the water tank 53 is automatically replenished to the driven chamber 421 through the fluid-replenishing pipe 533 due to the height difference under the principle of the communicating vessel, and the driven chamber 421 is simultaneously expanded by the replenishing fluid until the fluid level in the driven chamber 421 or the drain pipe 60 reaches the predetermined level 535.

The driven chamber 421 compresses the driving chamber 411 through the transmission of the transmission assembly 43, and the fluid discharged from the compressed driving chamber 411 flows to the water tank 53 through the primary side switching valve member 51. Referring specifically to fig. 2A and 3, as the driven chamber 421 expands due to the replenishment of fluid from the tank 53, it reacts against the drive chamber 411 via the drive assembly 43, and the drive chamber 411 is compressed and discharges fluid to the tank 53. Since the fluid in the tank 53 can supplement the driven chamber 421, the accumulated water in the driving chamber 411 can indirectly supplement the driven chamber 421.

In the embodiment shown in fig. 2A and 3, when the liquid level in the driven chamber 421 or the drain pipe 60 is lower than the predetermined liquid level 535, a water supplement command is generated and acts on the check valve 534 to conduct the check valve 534. The fluid in the tank 53 can thus be replenished to the driven chamber 421 through the replenishing pipe 533 and the check valve 534. When the level in the slave chamber 421 or the drain 60 rises to greater than or equal to the predetermined level 535, the level of the fluid between the slave chamber 421 and the tank 53 reaches equilibrium, and the water refill command is thus cancelled and the one-way valve 534 is blocked. The flow path from the tank 53 to the driven chamber 421 is simultaneously closed.

The level control 531 may feed back to the intake valve 532 in a number of ways.

The liquid level control member 531 floats on the liquid level in the water tank 53, and the liquid level control member 531 switches the liquid inlet valve 532 on and off through mechanical transmission, photoelectric sensing, pressure-sensitive sensing, hall effect or other feedback coordination modes according to the floating height. When the liquid level in the tank 53 is lower than a predetermined level, the liquid level control member 531 floats down to open the inlet valve 532, so that the fluid supply source 700 supplies fluid to the tank 53 through the inlet valve 532, and the liquid level in the tank 53 rises as the fluid is supplied. When the level of fluid in tank 53 is above a predetermined level, fluid level control 531 causes intake valve 532 to close, preventing fluid from replenishing tank 53.

In the embodiment shown in fig. 2A and 3, the liquid level control member 531 switches the on-off state of the liquid inlet valve 532 through lever actuation.

The drain instruction may also be overridden when other conditions are reached.

In other embodiments, the draining command is cancelled after the slave chamber 421 is compressed to a predetermined extent, the switch control member 52 is triggered to stop the flow path for external fluid to be injected into the driving chamber 411, and the driving chamber 411 stops expanding to complete the compression process of the slave chamber 421. Alternatively, when the water supplement command is received, the drain command is cancelled, and the switch control member 52 closes the flow path for injecting the external fluid into the driving chamber 411 after the drain command is cancelled.

The drain 60 may also restrict the spontaneous flow of fluid from the driven chamber 421 by other means.

In the foregoing embodiment, the drain pipe 60 has a level at least partially higher than that of the driven chamber 421. In some embodiments, not shown, the drain pipe 60 and the transition 4211 may be disposed lower than the main body of the driven chamber 421, and the driven chamber 421 is communicated with the transition 4211 from the bottom side thereof. By providing a pressure valve, an electromagnetic valve, or the like in the drain pipe 60 and the transition 4211, the fluid in the slave chamber 421 is prevented from being spontaneously injected into the drain pipe 60 by its own weight and discharged. When the driven chamber 421 is compressed by the expansion of the driving chamber 411, the pressure in the driven chamber 421 is increased to open the pressure valve member, so that the fluid in the driven chamber 421 enters the drainage pipe 60 and is discharged to the body 30. In this embodiment, the driven chamber 421 may communicate with the drain pipe 60 through its bottom side.

The driving assembly 41 further has a main base 412 and an active plate 414, wherein the main base 412 is connected to the body 30. The spatial expansion of the drive chamber 411 enables the active plate 414 to move away from the main mount 412. The driven assembly 42 has a pull plate 425. The transmission assembly 43 includes a support 431 and a pull-cord 432. When the driving chamber 411 is expanded by the driving external force, the support 431 moves away from the main seat 412 with the driving plate 414, so that the overlapping portion of the traction rope 432 between the main seat 412 and the support 431 increases. The pulling plate 425 is pulled by the pulling rope 432 to move and press another part of the driven chamber 421 to discharge the fluid.

The drive assembly 41 has a variety of configurations.

In some embodiments, not shown, the main seat 412 is fixedly attached within the body 30.

In the embodiment shown in FIG. 2B, the main housing 412 and the active plate 414 are used to form the inner wall of the drive chamber 411. More specifically, the drive assembly 41 also includes a primary side flexible member 415. The driving plate 414 is movably disposed through the inner cavity of the main base 412. Along the moving direction of the active plate 414 relative to the main seat 412, the active plate 414 and the main seat 412 are hermetically connected to different parts of the main side flexible member 415 to form a driving cavity 411 with a variable space size in cooperation. The driving assembly 43 is disposed between the driving plate 414 and the driven assembly 42. When the driving chamber 411 is expanded by the driving external force, the driving plate 414 exits the inner cavity of the main seat 412 and transmits the driving external force through the transmission assembly 43 to compress the driven chamber 421 to be smaller, so as to discharge the fluid in the driven chamber 421, and the expansion space variation of the driving chamber 411 is smaller than the compression space variation of the driven chamber 421. The driving cavity 411 is formed by hermetically connecting the main seat 412, the driving plate 414 and the main side flexible piece 415, and the main side flexible piece 415 is flexible and easy to shrink or expand and deform, so that the whole inner wall surface of the driving cavity 411 is kept complete, the sealing performance of the driving cavity 411 is enhanced, and fluid leakage in the driving cavity 411 is avoided. Because main side flexible piece 415 is self deformation in the shrink or expansion process, and the friction with other spare parts is less, and main side flexible piece 415 self adopts flexible material, so not fragile in the course of the work has longer life. Specifically, the main seat 412 is formed with a main side port 413 communicating with the drive chamber 411, and the main side port 413 is also connected to the main side switching valve member 51 to let the fluid go in and out of the drive chamber 411.

In other embodiments, the main seat 412 and the active plate 414 are configured to abut against an outer wall forming the drive cavity 411. When the inner space of the driving chamber 411 expands, the diameter of the outer wall of the driving chamber 411 expands synchronously and pushes the driving plate 414 in a direction away from the main seat 412. Specifically, in some embodiments not shown, the driving chamber 411 may be formed by an inner cavity of a flexible bag, and the main seat 412 and the active plate 414 abut against an outer wall of the flexible bag, so as to generate a pushing action between the main seat 412 and the active plate 414 when the flexible bag is inflated by injecting fluid, so as to move the active plate 414 away from the main seat 412.

The transmission assembly 43 has various structural forms.

In some embodiments, a support 431 connects the active plate 414. The pull cord 432 is in turn connected to the main seat 412, around the support 431 and to the pull plate 425. When the driving chamber 411 is expanded by an external driving force, the supporting member 431 moves away from the main seat 412 along with the driving plate 414, so that the tensile portion of the traction rope 432 between the main seat 412 and the driven plate 424 is increased, the tensile portion of the traction rope 432 between the supporting member 431 and the pull plate 425 is decreased, and the pull plate 425 is pulled by the traction rope 432 to press and discharge the fluid to the other part of the driven chamber 421. Since the overlap of the traction rope 432 between the main seat 412 and the support 431 is increased, the moving distance of the pulling plate 425 is greater than that of the driving plate 414 at the same time, and the compression space of the driven chamber 421 is greater than the expansion space of the driving chamber 411 in the case that the sectional sizes are close, so that more fluid is discharged from the driven chamber 421.

In the embodiment shown in fig. 2A, the main seat 412 is disposed between the support 431 and the path of movement of the pull plate 425, such that the stretch of the pull cord 432 between the support 431 and the pull plate 425 is parallel to the stretch of the pull cord 432 between the main seat 412 and the support 431. When the driving chamber 411 is expanded by the driving external force, the pulling plate 425 is pulled by the pulling rope 432 to move close to the main seat 412, so that the driven chamber 421 between the pulling plate 425 and the main seat 412 is squeezed, and the fluid in the part of the driven chamber 421 is discharged.

Understandably, in the embodiment shown in fig. 2A, when the tensile portion of the pulling rope 432 between the main seat 412 and the support 431 is increased by a predetermined length, the tensile portion of the pulling rope 432 between the support 431 and the pulling plate 425 will be decreased by a predetermined length, and although the overall length of the pulling rope 432 is not changed, the distance between the pulling plate 425 and the main seat 412 will be decreased by two predetermined lengths, and thus, the moving speed of the pulling plate 425 relative to the main seat 412 is twice the moving speed of the support 431 relative to the main seat 412.

In some embodiments, not shown, the tension of the pull cord 432 between the support 431 and the pull plate 425 may also form an acute angle with the tension of the pull cord 432 between the main seat 412 and the support 431.

In some embodiments not shown in the drawings, the movable path of the pulling plate 425 can be adjusted by adjusting the stretching direction of the pulling rope 432 between the supporting member 431 and the pulling plate 425 through the fixed pulley, so as to press the driven chamber 421 at other positions through the pulling plate 425.

In some embodiments, the support 431 is a pulley rotatably disposed with respect to the driving plate 414, and the pull rope 432 is wound around the edge of the pulley to reduce the friction force experienced by the pull rope 432 during the length distribution adjustment.

In some embodiments, not shown, the support 431 is rod-shaped, and the pull cord 432 passes around a radial edge of the support 431.

The driven assembly 42 can have a variety of configurations.

In the embodiment shown in fig. 2A, the driven chamber 421 is disposed between the pull plate 425 and the main seat 412, the main seat 412 being between the support 431 and the pull plate 425. When the driving chamber 411 expands, the supporting member 431 moves away from the main seat 412, and simultaneously, the driving assembly 43 drives the pulling plate 425 to move close to the main seat 412, so as to press the driven chamber 421 between the pulling plate 425 and the main seat 412 and discharge the fluid in the part of the driven chamber 421.

In some embodiments, not shown, the driven chamber 421 is disposed between the pull plate 425 and a partial inner wall of the body 30. When the driving chamber 411 is expanded, the supporting member 431 moves away from the main seat 412, and simultaneously, the pulling plate 425 is driven by the pulling rope 432 to move close to the partial inner wall of the body 30, so as to press the driven chamber 421 between the pulling plate 425 and the partial inner wall of the body 30 and discharge the fluid in the partial driven chamber 421.

In some embodiments, the driven assembly 42 has a driven plate 424. When the driving chamber 411 is expanded, the driven plate 424 moves along with the driving plate 414, and the driven plate 424 presses a portion of the plurality of driven chambers 421. Specifically, as shown in fig. 2A, the support 431 is connected to the driving plate 414 through the driven plate 424. More specifically, the transmission assembly 43 includes a transmission member 433, and the transmission member 433 is connected between the driving plate 414 and the driven plate 424, so that when the driving cavity 411 is expanded, the driving plate 414 can drive the driven plate 424 to move through the transmission assembly 43.

In the embodiment shown in fig. 2A, the driven assembly 42 further includes a fixed plate 426 coupled to the main housing 412. Another driven chamber 421 is provided between the driven plate 424 and the fixed plate 426. When the driving chamber 411 is expanded and the driven plate 424 moves by being transmitted by the driving plate 414, the driven plate 424 moves closer to the fixed plate 426 at the same time, and the driven chamber 421 between the driven plate 424 and the fixed plate 426 is pressed and the fluid is discharged. More specifically, as shown in fig. 2A, the driving plate 414 and the driven plate 424 are sequentially disposed between the main seat 412 and the fixing plate 426.

Further, the driven plate 424 and the fixed plate 426 abut against an outer wall forming the other driven chamber 421. When the driven plate 424 moves closer to the fixed plate 426, the driven plate 424 and the fixed plate 426 press the outer wall of the driven chamber 421 therebetween, and a part of the space of the driven chamber 421 is compressed to discharge the fluid. Specifically, as shown in fig. 2A, the driven assembly 42 further includes a secondary-side flexible bag 422, an inner cavity of the secondary-side flexible bag 422 is used as the driven cavity 421, and the driven plate 424 and the fixing plate 426 are respectively used for abutting against an outer wall of the secondary-side flexible bag 422. More specifically, the secondary flexible bag 422 has a secondary port 4221 and a secondary fluid infusion port 4222, and the fluid in the secondary flexible bag 422 is output from the secondary port 4221 to the drain pipe 60, and the fluid infusion pipe 533 infuses the fluid into the secondary flexible bag 422 through the fluid infusion port.

Further, the driven assembly 42 further includes a secondary side limit plate 423, and the fixed plate 426 is connected to the main seat 412 through the secondary side limit plate 423. The driven plate 424 and the driven chamber 421 are accommodated in the cavity formed by the secondary side limit plate 423. The fixing plate 426 can be kept fixed with respect to the main holder 412, and the deformation space of the secondary flexible bag 422 can be restricted by the secondary restriction plate 423.

In some embodiments not shown, the driven plate 424 or the fixed plate 426 may be used to form part of the inner wall of the driven chamber 421. More specifically, the driven plate 424 or the fixed plate 426 may form a driven cavity 421 having a variable size of space by cooperating with the flexible member. More specifically, two openings of a flexible sleeve may be sealingly connected to the driven plate 424 and the fixed plate 426, respectively.

In some embodiments, not shown, a further driven cavity 421 is provided between the driven plate 424 and the inner wall of the body 30. When the driving chamber 411 is expanded and the driven plate 424 moves by being transmitted by the driving plate 414, the driven plate 424 moves closer to the fixed plate 426 at the same time, so that the driven chamber 421 between the driven plate 424 and the body 30 is pressed and the fluid is discharged. More specifically, in some embodiments not shown, the driving plate 414 and the driven plate 424 are sequentially disposed between the main seat 412 and a partial inner wall of the body 30.

Further, in the embodiment shown in fig. 2A, in the case where the axial sectional size and the axial length of each driven chamber 421 are close, a single driven chamber 421 may be provided between the driven plate 424 and the fixed plate 426, and two driven chambers 421 may be provided between the pull plate 425 and the main seat 412. Or the number of the driven chambers 421 of the two parts is adjusted by multiple. More specifically, in fig. 2A, at least two secondary-side flexible bags 422 are disposed between the pulling plate 425 and the main seat 412, and a movable partition 427 is disposed between the secondary-side flexible bags 422 to uniformly transmit the pressure between the two secondary-side flexible bags 422. The movable partition 427 may be slidably disposed with respect to the main seat 412. The secondary-side flexible bag 422 between the pulling plate 425 and the main seat 412 may limit the expansion space by the additionally provided secondary-side restriction plate 423. More specifically, in fig. 2A, one end of the pull cord 432 is coupled to the main seat 412 and the other end is coupled to the pull plate 425.

In the embodiment shown in fig. 2A and 3, the specific implementation principle of the flushing mechanism 40 is as follows:

before the drainage of the driven chamber 421 is started, the secondary side flexible bag 422 between the driven plate 424 and the fixed plate 426 or the secondary side flexible bag 422 between the pulling plate 425 and the fixed plate 426 stores the fluid and expands sufficiently, and the fluid before driving is discharged in advance, so that the driving plate 414 goes deep into the inner cavity of the main seat 412 and is attached to one side of the main seat 412. At this time, since the driving plate 414 and the driven plate 424 are located close to the main seat 412, a stretched portion of the traction rope 432 between the main seat 412 and the support 431 is in a relatively short state, and a stretched portion of the traction rope 432 between the support 431 and the pulling plate 425 is in a relatively long state.

Upon initiating the draining of the slave chamber 421, fluid begins to be injected into the drive chamber 411. The active plate 414 moves in a direction to exit the cavity of the main seat 412 due to the pressure of the fluid. Meanwhile, the driving plate 414 pushes the driven plate 424 towards the fixing plate 426 through the transmission member 433, and the driven plate 424 and the fixing plate 426 jointly press the secondary-side flexible bag 422 therebetween, so that the fluid in the secondary-side flexible bag 422 between the driven plate 424 and the fixing plate 426 is discharged. As the driven plate 424 moves toward the fixed plate 426, since one end of the pulling string 432 is connected to the main socket 412, the support 431 increases the tensile portion of the pulling string 432 between the main socket 412 and the support 431 with the movement of the driven plate 424, and the tensile portion of the pulling string 432 between the support 431 and the pulling plate 425 decreases, the pulling plate 425 is moved toward the main socket 412 by the pulling string 432, so that the pulling plate 425 presses the two secondary-side flexible bags 422 between the pulling plate 425 and the main socket 412, and the fluid in the secondary-side flexible bags 422 between the pulling plate 425 and the main socket 412 is discharged. Because the expansion of the driving cavity 411 causes the spatial compression of the secondary side flexible bags 422, under the condition that the difference between the average sectional areas of the driving cavity 411 and the secondary side flexible bags 422 is not obvious, the sum of the spatial contraction amounts of the secondary side flexible bags 422 is larger than the spatial expansion amount of the driving cavity 411, so that the flushing mechanism 40 can discharge fluid with larger volume in a short time, and the problem that the body 30 of the sanitary ware 100 is not flushed cleanly under low water pressure is solved. Or less water is used to meet the flushing effect, thus meeting the current concept of energy conservation and environmental protection. Meanwhile, since a booster pump does not need to be additionally added, the complicated structure, the increased cost or the decreased stability of the flushing mechanism 40 are avoided.

After the drainage of the driven chamber 421 is completed, the fluid is replenished into the secondary side flexible bag 422, and the pressure of the fluid in the secondary side flexible bag 422 causes the secondary side flexible bag 422 to have a horizontal expansion tendency. In one aspect, the outer wall of the secondary side flexible pocket 422 between the driven plate 424 and the fixed plate 426 pushes the driven plate 424 in a direction closer to the main socket 412. On the other hand, the outer wall of the secondary-side flexible bag 422 between the pull plate 425 and the main seat 412 pushes the pull plate 425 in a direction away from the main seat 412, and the pull plate 425 pushes the support 431 and the driven plate 424 in a direction close to the main seat 412 through the pulling string 432 while moving away from the main seat 412. At the same pressure, since the number of the secondary flexible bags 422 is greater than that of the driving chambers 411, each driven chamber 421 has a larger sum of force-bearing areas, so that the expansion force of the driven chamber 421 is greater than the fluid pressure in the driving chamber 411, and thus the driving chamber 411 is compressed to discharge the fluid.
