Technical Field

The utility model relates to a sanitary bath equipment technical field especially relates to a bath mechanism, drainage device and sanitary bath equipment.

Background

The intelligent closestool is used as bathroom equipment, and the development trend is that the thinner the cover plate is, the more the cover plate is flat, so that the attractiveness is improved, and the indoor space is saved. The ceramic water tank of traditional closestool need satisfy the high requirement, just has enough potential energy and water volume to let the closestool wash clean, but the height of ceramic water tank often leads to occupying great indoor space, makes this kind of mode eliminated gradually.

The ceramic-free water tank toilet structure on the market is usually flushed by directly utilizing the water pressure of tap water, and the requirement on the water pressure is high. However, the old community has unstable water pressure, and when the water pressure is insufficient, the water source output flow rate is slow, so that the washing and the rinsing cannot be guaranteed.

In addition, the water quantity of the closestool without the ceramic water tank is ensured by arranging a booster pump, but the mode causes the closestool to have a complex structure, and is expensive and easy to damage.

Referring to fig. 1 to 7, a sanitary ware 100 according to an embodiment of the present invention includes a drainage device 20 and a body 30 connected to the drainage device 20, wherein the body 30 is provided with a liquid pool 31, and a drain outlet 311 is disposed at the bottom of the liquid pool 31. 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. As shown in fig. 6 and 7, drain 20 includes a flush mechanism 40 and a regulating assembly 50 connected to flush mechanism 40. The body 30 may have a washing waterway 32 to guide the fluid to an upper side of the liquid pool 31 so that the fluid can uniformly wash the inner wall of the liquid pool 31 from the top down. The body 30 may further include a spray waterway 33 and a siphon pipe 34 connected to the drain outlet 311, wherein the spray waterway 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 drain outlet 311 and the siphon pipe 34.

Referring to fig. 1 to 4, the present invention provides a flushing mechanism 40, including: a driving assembly 41, a driven assembly 42 and a transmission assembly 43. The driving assembly 41 has a driving chamber 411 for accommodating fluid and having a variable size of space. The driven assembly 42 is provided with a driven cavity 421 which is used for containing fluid and has a variable space size, and the number of the driven cavities 421 is multiple. The number of driven chambers 421 is greater than the number of driving chambers 411. The transmission assembly 43 is disposed between the driving assembly 41 and the driven assembly 42. When the driving chamber 411 is expanded by the driving external force, the transmission assembly 43 can be driven, and the driving external force is transmitted by the transmission assembly 43, so that the driven chamber 421 is compressed and reduced to discharge the fluid stored in the driven chamber 421. When the driving chamber 411 is expanded by the driving external force, the expansion space variation amount is smaller than the sum of the compression space variation amounts of the driven chambers 421.

By injecting a fluid into each slave chamber 421 in advance, the internal space of each slave chamber 421 is sufficiently expanded, and at the same time, the driving chamber 411 is evacuated in advance, so that the driving 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 spatially expanded due to the filling of the fluid; the driving chamber 411 transmits driving external force to the transmission assembly 43 when expanding, and the driven chambers 421 are compressed by the transmission action of the transmission assembly 43, so that the fluid stored in each driven chamber 421 is simultaneously discharged to the body 30 of the sanitary ware 100. Since the sum of the spatial variation amounts of all the plurality of driven chambers 421 is greater than that of a single driving chamber 411 or the sum of the spatial variation amounts of all the plurality of driven chambers 421 is greater than that of the plurality of driving chambers 411 when the driving chamber 411 is expanded, the amount of fluid simultaneously discharged from each of the driven chambers 421 is greater than the amount of fluid introduced into the driving chamber 411. In the drainage process, the flushing flow can be ensured by using the driving external force borne by the driven cavity 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.

Referring to fig. 6 and 7, the fluid discharged to the main body 30 of the sanitary ware 100 can uniformly wash the inner wall of the main body 30 through the washing waterway 32, or can enter the siphon 34 through the spraying waterway 33, so that the dirt at the bottom of the liquid pool 31 is sucked and discharged.

In some embodiments, the inner walls of the drive chamber 411 are at least partially flexible.

Referring to fig. 1 and 3, in one embodiment, the driving assembly 41 includes a primary side housing 412, a primary side plate 414, and a primary side flexible member 415. The active board 414 is movably received in the primary side housing 412, and a primary side flexible member 415 is connected between the primary side housing 412 and the active board 414. Along the expansion direction of the driving chamber 411, the driving plate 414 and the primary side housing 412 are hermetically connected to different parts of the primary side flexible member 415 to form the driving chamber 411 in a matching manner. The driving plate 414 is connected to the driving assembly 43, and during the movement of the driving plate 414, the driving assembly 43 moves synchronously. The primary side housing 412 is provided with a primary side port 413 communicating with the drive chamber 411, and fluid flows into or out of the drive chamber 411 through the primary side port 413. The primary side flexible member 415 has a cylindrical shape, one end of which is connected to the active plate 414 or fixedly embedded in the active plate 414, and the other end of which is connected to the primary side housing 412 or fixedly embedded in the primary side housing 412. In one embodiment, a gap is provided between the edge of the active plate 414 and the inner wall of the primary side housing 412 to facilitate movement of the active plate 414 within the primary side housing 412. Further, primary side flexible member 415 is tapered to have a large end and a small end, the small end being connected to active plate 414 and the large end being connected to primary side housing 412.

In one embodiment, the interior walls of the driven chamber 421 are at least partially flexible.

Referring to fig. 1 and 2, in one embodiment, the driven assembly 42 includes a secondary flexible bag 422, and an inner cavity of the secondary flexible bag 422 is used as a driven cavity 421; when the driving chamber 411 is expanded by the driving external force, the transmission assembly 43 is driven to compress the secondary flexible bag 422 to be smaller, so as to discharge the fluid in the driven chamber 421.

Referring to fig. 1 and 2, in one embodiment, the driving assembly 43 includes a supporting plate 431, a secondary pushing plate 432 and a transmitting member 433. The minor flexible bag 422 is disposed between the support plate 431 and the minor pusher plate 432. The transmission member 433 couples the secondary push plate 432 to the drive assembly 41, and more particularly to the active plate 414 in the drive assembly 41. When the driving cavity 411 is expanded by external driving force, the driving cavity 411 acts on the secondary push plate 432 through the transmission member 433, so that the secondary push plate 432 moves close to the supporting plate 431 to compress the secondary flexible bag 422. The number of support plates 431 and secondary push plates 432 may be the same or different than the number of secondary flexible bags 422. For example, in one embodiment, one secondary flexible bag 422 can be disposed between a respective one of the support plates 431 and the secondary pusher 432, or a plurality of secondary flexible bags 422 can be disposed. All of the secondary side push plates 432 are connected to a pass through 433. In the embodiment shown in FIG. 1, the secondary push plates 432 are indirectly connected to the delivery member 433, i.e., each secondary push plate 432 is connected in series and then directly connected to the delivery member 433 by one secondary push plate 432 closest to the delivery member 433. In another embodiment, the connection between the secondary push plate 432 and the transmission member 433 may be a direct connection, for example, a direct-connection transmission rod is disposed between each primary push plate 432 and the transmission member 433. In some embodiments, the support plates 431 are fixedly coupled to each other. Further, the respective support plates 431 are connected to each other and also fixedly connected to the main side case 412.

In the embodiment shown in fig. 1 and 2, the secondary flexible pouches 422 are identical in shape and size. In some embodiments not shown, the shape of each of the secondary side flexible bags 422 may vary. In some embodiments not shown, the size of each secondary side flexible bag 422 may vary.

Further, the transmission assembly 43 further includes a secondary side limiting plate 434, and the secondary side limiting plate 434 extends along a direction parallel to the moving track of the secondary side push plate 432; projected on a plane perpendicular to the path of motion of the secondary push plate 432, the secondary confinement plates 434 extend or are distributed around the secondary flexible bag 422 to confine the deformation space of the secondary flexible bag 422. The secondary side stop plates 434 may serve as an intermediate connection to each of the secondary side push plates 432, and during movement of the secondary side push plates 432, the secondary side stop plates 434 follow the secondary side push plates 432 together. The secondary limiting plate 434 may also be fixedly connected to the supporting plate 431, and during the movement of the secondary push plate 432, the secondary push plate 432 moves relative to the secondary limiting plate 434 and the supporting plate 431, and the secondary flexible bag 422 is compressed and deformed in the space defined by the secondary limiting plate 434 and the supporting plate 431.

Referring to fig. 1 and 4, in one embodiment, the driven chambers 421 are distributed along a predetermined line 423; the preset line 423 is a straight line, an arc, a circumferential line, or a spiral line; in another embodiment, the driving chamber 411 and each driven chamber 421 may be distributed along a preset line 423 one by one; the predetermined line 423 is a straight line, a circular arc, a circumferential line, or a spiral line. In some embodiments, the number of the driving chamber 411 may be one or more, but the number of the driving chamber 411 is less than the number of the driven chamber 421. While the sum of the expanding space variation amounts of the driving chamber 411 is smaller than the sum of the compressing space variation amounts of the driven chamber 421.

Referring to fig. 5A and 5B, the adjusting and controlling assembly 50 is used to control the connection and disconnection between the driving cavity 411 and the fluid supply source 700, and the fluid input into the driving cavity 411 generates a driving external force on the driving cavity 411, so as to expand the driving cavity 411; the regulation assembly 50 also serves to regulate fluid replenishment from the driven chamber 421; after the compression of the driven chamber 421 is completed, the regulating assembly 50 is also used for guiding and supplementing the fluid in the driving chamber 411 to the driven chamber 421, and 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. In some embodiments, the fluid supply 700 is the output of a municipal tap water line, and the fluid injected into the driving chamber 411 or the driven chamber 421 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.

In some embodiments, the regulating assembly 50 includes a primary side switching valve element 51 and a switch control element 52; the main-side switching valve member 51 is connected between the fluid supply source 700 and the driving chamber 411, and when the switching control member 52 is activated, the fluid supply source 700 and the driving chamber 411 are communicated through the main-side switching valve member 51, and the main-side switching valve member 51 blocks a flow passage communicating between the driving chamber 411 and the driven chamber 421, and also blocks a flow passage communicating between the driving chamber 411 and other fluid storage containers if a flow passage communicating between the driving chamber 411 and other fluid storage containers exists. The drain 20 also includes a drain 60 in communication with the driven chamber 421, the drain 60 leading to the sump 31 to direct fluid discharged from the driven chamber 421 toward the sump 31. Specifically, the drain pipe 60 has at least a part of a higher level than the driven chamber 421, which is the high-level section 62 of the drain pipe 60. Further, each slave chamber 421 is transitionally connected with the drain pipe 60 through a junction 424, and the level of the junction 424 is higher than the main 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. 5A and 5B, the driven chambers 421 communicate from their top sides to the junction 424, respectively.

Before the fluid level in the driven chamber 421 and the drain 60 rises above the high level section 62 of the drain 60, fluid is confined in the driven chamber 421 or the junction 424 to avoid the fluid in the driven chamber 421 from spontaneously flowing around the drain 60 under its own weight. When the driven chamber 421 is compressed, the liquid level in the driven chamber 421 and the drain pipe 60 rises to pass over the high-level section 62 of the drain pipe 60, and flows out into the body 30. In some embodiments, not shown, the drain pipe 60 and the junction 424 may be disposed lower than the driven chamber 421, and the driven chamber 421 communicates with the junction 424 from the bottom side thereof. By providing a valve such as a pressure valve or an electromagnetic valve in the drain pipe 60 and the junction 424, the fluid in the driven chamber 421 is prevented from being spontaneously filled 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.

Referring to fig. 5A and 5B, in another embodiment, the switch control member 52 is a valve structure or a manual valve, when the switch control member 52 is turned on, tap water in the municipal tap water pipeline passes through the switch control member 52 and 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 a state in which the municipal tap water pipeline is communicated with the driving cavity 411 and the driving cavity 411 is isolated from the driven cavity 421, the injection of tap water moves the driving plate 414 away from the primary side housing 412 and the driving cavity 411 tends to expand, the driving plate 414 acts on the secondary side push plate 432 through the transmission member 433 and pushes the secondary side push plate 432 toward the supporting plate 431, thereby respectively squeezing the plurality of secondary side flexible bags 422, so that the water stored in the driven cavity 421 is discharged to the body 30 of the sanitary ware 100, so as to output a larger volume of water to the body 30.

Referring to fig. 5A and 5B again, in order to facilitate automatic control of the supplementary water injection from the driven chamber 421, the regulating assembly 50 further includes a water tank 53, the water tank 53 is connected to a liquid level control member 531, a liquid inlet valve 532, a liquid supplementing pipe 533 and a check valve 534, the liquid inlet valve 532 is disposed between the water tank 53 and the fluid supply source 700, and the liquid level control member 531 maintains the fluid in the water tank 53 at a predetermined liquid level 535 by adjusting the on-off state of the liquid inlet valve 532; the inner cavity of the water tank 53 is connected with the driven cavity 421 through a liquid supplementing pipe 533, and the one-way valve 534 is arranged on the liquid supplementing pipe 533 so as to prevent the fluid in the driven cavity 421 from flowing back to the water tank 53; the slave chamber 421 is positioned below a predetermined level 535.

In the embodiment shown in fig. 5A, when the drainage device 20 receives a drainage command and the switch control member 52 is turned on, tap water in the municipal tap water pipeline passes through the switch control member 52 and presses the water pressure on the primary side switching valve member 51, the primary side switching valve member 51 of the three-way structure is switched to a state in which the municipal tap water pipeline is communicated with the driving chamber 411 and the driving chamber 411 is isolated from the water tank 53, the main water is injected to move the driving plate 414 away from the primary side housing 412 and expand the driving chamber 411, the driving plate 414 acts on the secondary side push plate 432 through the transmission member 433 and pushes the secondary side push plate 432 toward the supporting plate 431 to respectively press the plurality of secondary side flexible bags 422, so that the water stored in the driven chamber 421 is drained from the drainage pipe 60 to output a larger volume of water to the body 30. In some embodiments, the switch control 52 is connected between the primary side switching valve member 51 and the fluid supply source 700; the switch control member 52 is an electromagnetic control valve, when the switch control member 52 is controlled to be turned on, the pressure of the fluid switches the main side switching valve member 51 to open the flow passage between the driving cavity 411 and the fluid supply source 700 and to close the flow passage between the driving cavity 411 and the water tank 53; after the stored water in the slave chamber 421 is sufficiently discharged, the switching control member 52 is controlled to be turned off, and the driving chamber 411 loses the driving external force provided by the fluid to complete the compression of the slave chamber 421. Before the stored water in the slave chamber 421 is sufficiently discharged, if the switching control member 52 is controlled to be turned off or the fluid supply source 700 stops outputting, 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.

Referring to fig. 5A, after the compression of the driven chamber 421 is completed or interrupted, the gravity of the accumulated water in the secondary flexible bag 422 generates a pressure on the inner wall of the secondary flexible bag 422, and the secondary flexible bag 422 expands and deforms under the pressure to cause the liquid level in the secondary flexible bag 422 or the drainage pipe 60 to drop. Since the placing height of the driven chamber 421 is lower than the predetermined level 535 and the water tank 53 is connected to the secondary side flexible bag 422 through the fluid-replenishing pipe 533, when the liquid level in the secondary side flexible bag 422 or the drain pipe 60 is lower than the predetermined level 535, the tap water in the water tank 53 is spontaneously replenished to the secondary side flexible bag 422 through the fluid-replenishing pipe 533 until the liquid level in the secondary side flexible bag 422 or the drain pipe 60 reaches the predetermined level 535 under the communicating principle.

The level control 531 may provide feedback through a multi-form inlet valve 532 to maintain the level 535 of the liquid in the tank 53 at a predetermined level.

In the embodiment shown in fig. 5A and 5B, a liquid inlet valve 532 is connected between the fluid supply source 700 and the water tank 53; the liquid level control member 531 floats in the water tank 53, and switches the liquid inlet valve 532 on and off according to the floating height. When the level control member 531 floats to a level higher than or equal to the predetermined level 535, the level control member 531 puts the inlet valve 532 into a shut-off state by lever actuation, preventing the tap water from entering the tank 53. When the liquid level control member 531 floats to be lower than the predetermined liquid level 535, the liquid level control member 531 makes the liquid inlet valve 532 enter an open state through lever transmission, so that tap water is supplemented to the water tank 53 until the liquid level control member 531 floats to be higher than or equal to the predetermined liquid level 535, and the liquid inlet valve 532 is turned off again.

In some embodiments, not shown, the up-and-down floating variation of the liquid level control member 531 can also be transmitted by pressure-sensitive sensing, hall effect or other sensing means to adjust the on-and-off of the liquid inlet valve 532. Specifically, the liquid level control member 531 floats on the liquid level in the water tank 53, when the liquid level in the water tank 53 is lower than the predetermined liquid level 535, the liquid level control member 531 makes the liquid inlet valve 532 open by photoelectric sensing, pressure-sensitive sensing or other transmission sensing coordination when floating, and the circulation supply source 700 supplements the fluid to the water tank 53 through the liquid inlet valve 532; when the liquid level in the tank 53 is higher than the predetermined level 535, the liquid level control 531 closes the liquid inlet valve 532 by photoelectric sensing, pressure sensitive sensing or other cooperation means, and stops the supply of the liquid into the tank 53.

In other embodiments, the level control 531 is not limited to a floating member, and any other suitable arrangement between the level control 531 and the inlet valve 532 that maintains the predetermined level 535 of the fluid in the tank 53 may be used.

Referring to fig. 5A, since the main-side switching valve member 51 is connected between the driving chamber 411 and the water tank 53, when the water discharge command is cancelled after a certain time, the switch control member 52 connected between the main-side switching valve member 51 and the fluid supply source 700 is controlled to be turned off, the main-side switching valve member 51 loses the pressure effect of the fluid, and the main-side switching valve member 51 of the three-way structure is switched to a state in which the driving chamber 411 is communicated with the water tank 53 and the fluid supply source 700 is isolated from the driving chamber 411, so that the accumulated water in the driving chamber 411 is guided to be replenished to the water tank 53.

The fluid in the tank 53 is automatically replenished into the driven chamber 421 due to the difference in level, and the driven chamber 421 is expanded due to the replenishment of the fluid. 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 to fig. 5A and 5B, when the secondary flexible bag 422 expands due to the supply of tap water from the water tank 53, the secondary push plate 432 is pushed away from the support plate 431, the secondary push plate 432 reacts to the driving plate 414 through the transmission member 433, so that the driving plate 414 moves closer to the primary housing 412, and the driving chamber 411 is compressed to discharge the fluid to the water tank 53. Specifically, the accumulated water in the driving chamber 411 flows to the water tank 53 through the main-side port 413 and the main-side switching valve member 51 in order to replenish the stored water in the water tank 53. Since the tap water in the water tank 53 can supplement the driven chamber 421, the accumulated water in the driving chamber 411 can be indirectly supplemented to the driven chamber 421.

Referring to FIG. 5A, a portion of the drain 60 is positioned above a 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 which must be disposed at a high position to generate potential energy to drain the water toward the drain pipe 60, the water tank 53 is disposed at a more flexible position and the overall volume of the drain device 20 can be reduced, thereby improving the external layout. Further, in order to prevent the accumulated water discharged from the drainage pipe 60 from continuously sucking tap water into the drainage pipe 60 under negative pressure from the water tank 53, the fluid infusion pipe 533 and the secondary side flexible bag 422 in sequence, the drainage device 20 further includes a siphon release valve 61 connected to the drainage pipe 60, wherein the siphon release valve 61 is connected to a portion of the drainage pipe 60 higher than the predetermined liquid level 535. When the secondary flexible bag 422 is compressed and the stored water is discharged through the drain pipe 60, the siphon release valve 61 isolates the inside and outside air pressure environments of the drain pipe 60 under the high pressure of the stored water, preventing the stored water from leaking through the siphon release valve 61. 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 secondary side flexible bag 422. The siphon release valve 61 communicates the air pressure environment inside and outside the drain pipe 60 by 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. 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.

In other embodiments, the draining command is removed after the slave chamber 421 is compressed to some extent, the switching control element 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 removed, and the switching control member 52 closes the flow path for injecting the external fluid into the driving chamber 411 after the drain command is removed.

In some embodiments, the water replenishing command is removed after a predetermined time, so that the flow path for injecting the external fluid into the slave chamber 421 is cut off, and the slave chamber 421 stops expanding to complete the water replenishing process of the slave chamber 421; or, the water replenishing instruction is removed after the driven cavity 421 is expanded to a certain extent, so that the flow channel for injecting the external fluid into the driven cavity 421 is stopped, and the driven cavity 421 stops expanding to complete the water replenishing process of the driven cavity 421; or, when the water discharge command is received, the water supplement command is removed, and the removal of the water supplement command stops the external fluid from being injected into the flow channel of the slave chamber 421.

Referring to fig. 6 and 7, in order to provide a sanitary ware 100 according to an embodiment of the present invention, the drainage device 20 is accommodated in the body 30 such that the height of the drainage device 20 is lower than the upper edge of the liquid pool 31, thereby facilitating the control of the volume of the sanitary ware 100. In the embodiment shown in fig. 6, the driven member 42 is disposed laterally within the body 30, and the main body of the tank 53 is disposed above the upper edge of the driven member 42 and below the upper edge of the liquid bath 31. The body 30 is provided with an internal cavity at one side of the reservoir 31 in which the driven assembly 42 is received. Further, the inner cavity also houses the drive assembly 41. In some embodiments not shown, the driven assembly 42 can also be disposed in the body 30 in other orientations. The conditioning assembly 50 may be attached to the body 30 or external to the body 30.

In the embodiment shown in fig. 6, a part of the washing water path 32 is distributed around the upper edge of the liquid pool 31. The body 30 has a liquid outlet 321 communicated with the washing water path 32. The output ports of part of the secondary side flexible bags 422 in the driven assembly 42 are directly communicated to the washing water channel 32, when the secondary side flexible bags 422 are compressed to discharge the stored water, the stored water flows around the edge of the liquid pool 31 along the washing water channel 32, and the water flow in the washing water channel 32 flows to the inner wall of the liquid pool 31 through the liquid outlet holes 321 to generate washing effect on the inner wall of the liquid pool 31 from different angles. In some embodiments not shown, the water injection path 33 may also supply water by other means, and all the output ports of the driven chamber 421 are communicated to the washing water path 32 through the water discharge pipe 60, so that all the stored water in the driven chamber 421 is collectively output to the inner wall of the washing liquid tank 31.

In the embodiment shown in fig. 6, the output port of a portion of the secondary side flexible bag 422 in the driven assembly 42 is communicated to the jet waterway 33 through the drain pipe 60. The connection between the water spray path 33 and the siphon 34 is located at the lower side of the sewage discharge opening 311 of the liquid pool 31, and when water flows through the connection between the water spray path 33 and the siphon 34, the flow rate of the water flow is such that negative pressure is formed at the lower side of the sewage discharge opening 311, so that the dirt and accumulated water in the liquid pool 31 are sucked out of the liquid pool 31 from the sewage discharge opening 311 and finally discharged out of the body 30 along with the siphon 34. In some embodiments, not shown, the washing water path 32 may be supplied with water by other means, and all the output ports of the driven chamber 421 are communicated to the spraying water path 33 through the drain pipe 60, so that all the stored water of the driven chamber 421 is collected through the lower side of the sewage discharge port 311.

s20: if a drainage instruction is received, external fluid enters the driving cavity 411, the driving cavity 411 expands and generates driving external force, the driven cavity 421 compresses and discharges the fluid contained in the driven cavity 421, and the compression process of the driven cavity 421 is completed or interrupted;

s30: if a water replenishing command is received, external fluid is made to enter the driven cavity 421 to expand the driven cavity 421 and compress the driving cavity 411, and the fluid in the driving cavity 411 is transferred to the driven cavity 421 or the water tank 53 until the water replenishing process of the driven cavity 421 is completed or interrupted.

In the present embodiment, when the external fluid is injected into the driving chamber 411, a flow path for the driving chamber 411 to discharge the fluid to the driven chamber 421 is blocked. The drain instruction is removed after the preset time is continued, so that the flow channel for injecting the external fluid into the driving cavity 411 is cut off, the driving cavity 411 stops expanding, and the compression process of the driven cavity 421 is completed; after the compression process of the driven chamber 421 is completed, a water supplement command is generated, and a flow path for injecting the external fluid into the driven chamber 421 or the water tank 53 is opened. When a water replenishing command is received, a flow passage for leading fluid out of the driving chamber 411 to the driven chamber 421 is opened. The water replenishing command is removed after the preset liquid level 535 in the driven chamber 421 is reached, so that the flow channel for injecting the external fluid into the driven chamber 421 is cut off, and the driven chamber 421 stops expanding to finish the water replenishing process of the driven chamber 421.
