The utility model provides a sanitary device (not shown) which comprises a flushing mechanism and a body connected with the flushing mechanism. Specifically, the body is sunken to be formed with the liquid reserve tank, has seted up the drain on the diapire of liquid reserve tank, and bath mechanism can the exhaust fluid to export the internal face or the drain of liquid reserve tank with the fluid, wash the inner wall of liquid reserve tank, and discharge the filth from the drain. The sanitary equipment can be equipment needing flushing, such as a closestool, a wash basin table, a bathtub and the like.

As shown in fig. 1, specifically, the flushing mechanism 10 includes a driving assembly 100, a driven assembly 200 and a transmission assembly 300. The driving assembly 100 has a driving chamber 110 for accommodating fluid and having a variable space. The driven assembly 200 has a driven chamber 210 for receiving a fluid and having a variable amount of space. Transmission assembly 300 provides force transmission between drive assembly 100 and driven assembly 200 such that when drive chamber 110 is forced to expand along first path K1, drive chamber 110 is able to drive transmission assembly 300 to move such that transmission assembly 300 forces driven chamber 210 to contract and discharge fluid along second path K2.

In the flush mechanism 10, it is necessary to fill the driven chamber 210 with a fluid in advance to fully expand the internal space of the driven chamber 210, and to evacuate the drive chamber 110 in advance to bring the drive chamber 110 into a contracted state. When the flushing operation is performed, the supply source capable of generating the driving external force injects the fluid into the driving chamber 110 in the contracted state, the driving chamber 110 is expanded along the first path K1 due to the filling fluid, and the expansion of the driving chamber 110 causes the driven chamber 210 to contract along the second path K2 under the driving action of the driving assembly 300, so that the fluid in the driven chamber 210 is discharged. The fluid discharged from the interior of the driving chamber 210 is output to a body in the sanitary equipment to wash the inner wall of the liquid storage tank or discharge the sewage from the sewage discharge port, i.e., the washing operation is realized.

In order to maintain the flushing mechanism 10 to achieve the function of multiple flushes, after one flushing operation is completed, the driven cavity 210 needs to be supplemented with fluid by the supply source capable of generating driving external force, the driven cavity 210 expands along the second path K2 due to the injection of fluid, and the transmission assembly 300 can be driven to move to force the driving cavity 110 to contract along the first path K1, so that the fluid in the driving cavity 110 is discharged, that is, the fluid supplementing operation of the driven cavity 210 is realized. Thus, after the fluid infusion operation of the driven cavity 210 is completed, the flushing operation can be performed again, so that the purpose of multiple flushing is achieved. In other embodiments, other structures may be additionally provided to effect retraction of drive chamber 110, rather than through drive assembly 300.

It should be noted that the "supply source capable of generating driving external force" may be an output of a municipal tap water line, and in this case, the fluid injected into the driving chamber 110 or the driven chamber 210 is tap water. In other embodiments, the "supply source capable of generating driving external force" may also be an output of a municipal tap water pipeline after passing through a pressure pump, or may also be a pumping output of external stored water of sanitary equipment through an external pump body. In addition, the "supply" for providing the expansion force to the driving lumen 110 during the irrigation operation may be the same as or different from the "supply" for providing the expansion force to the driven lumen 210 during the fluid replacement operation.

As shown in fig. 1, in some embodiments, the transmission assembly 300 includes a pulley amplifying structure 310 and a gear amplifying structure 320, the driving assembly 100, the pulley amplifying structure 310, the gear amplifying structure 320, and the driven assembly 200 are sequentially connected, and the driving chamber 110 can expand along the first path K1 due to the injection of the fluid and drive the pulley amplifying structure 310 and the gear amplifying structure 320 to sequentially act to force the driven chamber 210 to contract along the second path K2 to discharge the fluid. The pulley amplifying structure 310 and the gear amplifying structure 320 perform a transmission function between the driving assembly 100 and the driven assembly 200, and under the transmission function of the pulley amplifying structure 310 and the gear amplifying structure 320, the movement stroke amount of the driven cavity 210 on the second path K2 is amplified in two stages and is larger than the movement stroke amount of the driving cavity 110 on the first path K1.

It will be appreciated that expansion of drive chamber 110 along first path K1 during a flush operation can ultimately effect contraction of follower chamber 210 along second path K2 to effect a flush operation. Meanwhile, the pulley amplifying structure 310 can convert a smaller stroke quantity input by the driving cavity 110 into a larger stroke quantity to be output, thereby realizing a primary amplifying effect; the gear amplification structure 320 can take the stroke amount output by the pulley amplification structure 310 as an input, and further amplify the stroke amount to output the larger stroke amount of the driven cavity 210, so that the smaller stroke amount input by the driving cavity 110 is finally converted into the larger stroke amount output to the driven cavity 210 under the cooperation of the pulley amplification structure 310 and the gear amplification structure 320, and two-stage amplification of the stroke amount is realized.

As shown in fig. 1, the average cross-sectional area of the cross-section of the driving chamber 110 is equal to the average cross-sectional area of the cross-section of the driven chamber 210, and the amount of the movement stroke of the driven chamber 210 along the second path K2, which is greater than the amount of the movement stroke of the driving chamber 110 along the first path K1, causes the amount of the change in the space of the driven chamber 210 to be greater than the amount of the change in the space of the driving chamber 110, which means that the volume of the fluid discharged by the contraction of the driven chamber 210 during the flushing operation is greater than the volume of the fluid replenished by the driving chamber 110. Since the spatial changes of the driven chamber 210 and the driving chamber 110 are synchronized, meaning that the spatial changes are performed in the same time period, it is further obtained that the volume of fluid discharged from the driven chamber 210 per unit time is greater than the volume of fluid replenished from the driving chamber 110, i.e. the flow rate of fluid discharged from the driven chamber 210 is greater than the flow rate of fluid replenished from the driving chamber 110.

It should be noted that in the case that the average cross-sectional area of the cross-section of the driving chamber 110 is smaller than the average cross-sectional area of the cross-section of the driven chamber 210, the "amount of the movement stroke of the driven chamber 210 along the second path K2 is larger than the amount of the movement stroke of the driving chamber 110 along the first path K1" can still make the amount of the spatial variation of the driven chamber 210 larger than the amount of the spatial variation of the driving chamber 110, thereby ensuring that the flow rate of the fluid discharged from the driven chamber 210 is larger than the flow rate of the fluid replenished from the driving chamber 110. However, in the case that the average cross-sectional area of the cross-section of the driving chamber 110 is larger than the average cross-sectional area of the cross-section of the driven chamber 210, it is only necessary that the degree of the movement stroke amount of the driven chamber 210 along the second path K2 is sufficiently larger than the movement stroke amount of the driving chamber 110 along the first path K1, and the negative influence caused by the smaller average cross-sectional area of the cross-section of the driven chamber 210 can be offset, and the amount of the spatial variation of the driven chamber 210 can still be larger than the amount of the spatial variation of the driving chamber 110, so that it is ensured that "the flow rate of the fluid discharged from the driven chamber 210 is larger than the flow rate of the fluid replenished by the driving chamber 110".

Further, it is understood that the "cross-section of the driving chamber 110" refers to a section taken by making a plane perpendicular to the first path K1 and cutting the driving chamber 110 with the plane. Since there are many planes perpendicular to the first path K1, there are many cross sections obtained after these planes cut the driving chamber 110, and the average value obtained after summing the areas of all the cross sections is the average cross section. When the driving chamber 110 has a regular cylindrical shape, all cross-sectional areas are equal, and at this time, the end surface area of the driving chamber 110 is equal to the average cross-sectional area. Similarly, the "cross section of the driven cavity 210" refers to a plane perpendicular to the second path K2, and a plurality of planes perpendicular to the second path K2 are provided, so that a plurality of sections are obtained after the planes cut the driven cavity 210, and the average cross section is obtained by summing the areas of all the sections. When the driven chamber 210 has a regular cylindrical shape, all the cross-sectional areas are equal, and at this time, the end surface area of the driven chamber 210 is equal to the average cross-sectional area.

As can be understood from the above analysis, in the present application, the amount of spatial variation of the driven chamber 210 is larger than that of the driving chamber 110 due to the dominant factor of the amount of movement stroke of the driven chamber 210 along the second path K2 being larger than that of the driving chamber 110 along the first path K1, and the influence of the magnitude relation between the average cross-sectional area of the cross-section of the driven chamber 210 and the average cross-sectional area of the cross-section of the driving chamber 110 on the difference between the amounts of spatial variation of the driven chamber 210 and the driving chamber 110 is not considered.

In the flushing mechanism 10, the transmission assembly 300 is provided to transmit the acting force between the driving chamber 110 and the driven chamber 210 through the transmission assembly 300, and the driven chamber 210 is contracted through the expansion of the driving chamber 110 under the transmission action of the transmission assembly 300, so as to flush. Further, the pulley amplifying structure 310 and the gear amplifying structure 320 in the transmission assembly 300 work together to convert a small stroke input from the driving chamber 110 into a large stroke output to the driven chamber 210, and implement two-stage amplification of the stroke, so as to achieve the purpose that the space variation of the driven chamber 210 is larger than the space variation of the driving chamber 110, and thus, the flow rate of the fluid discharged from the driven chamber 210 is larger than the flow rate of the fluid supplemented by the driving chamber 110, so that the fluid discharged from the driven chamber 210 has a large flow rate under the condition that the flow rate of the supply source is small, thereby satisfying the flushing requirement of the sanitary ware, and achieving a good flushing effect. In addition, since the driven chamber 210 is pre-filled with fluid, a large flow rate of fluid discharged from the driven chamber 210 can be ensured every time a flushing operation is performed. In addition, only need carry out reasonable overall arrangement to the flushing structure, set up low price's mechanical transmission subassembly 300, can reach above-mentioned effect, compare with additionally setting up high booster pump, the 10 costs of the mechanism of washing by water of this application are lower.

In some embodiments, the pulley amplifying structure 310 includes a first pulley 313, a second pulley 314, a first pull line 311 wound on the first pulley 313, and a second pull line 312 wound on the second pulley 314. The first pulley 313 is disposed coaxially with the second pulley 314 and is capable of rotating synchronously. The first traction rope 311 is coupled to the drive assembly 100 and the second traction rope 312 is coupled to the gear amplification structure 320. The diameter of the second pulley 314 is larger than that of the first pulley 313, and the movement stroke of the second traction rope 312 is larger than that of the first traction rope 311 after rotating a preset angle.

It will be appreciated that expansion of the drive chamber 110 moves the first traction rope 311 to become the motion input to the pulley amplifying structure 310, and the first traction rope 311 rotates the first pulley 313 and the second pulley 314 synchronously, thereby moving the second traction rope 312 to become the output of the pulley amplifying structure 310. Since the first traction rope 311 is wound around the first pulley 313 and the second traction rope 312 is wound around the second pulley 314, both the first traction rope 311 and the second traction rope 312 are tightened while the ends thereof are kept tangent to the respective pulleys during the movement of the two traction ropes. Further, since the diameter of the second pulley 314 is larger than that of the first pulley 313, in the process of synchronous rotation of the first pulley 313 and the second pulley 314, the linear velocity of the second traction rope 312 is larger than that of the first traction rope 311, so that the movement stroke of the second traction rope 312 is larger than that of the first traction rope 311, and thus, a smaller stroke input to the first traction rope 311 in the pulley amplifying structure 310 can be converted into a larger stroke of the second traction rope 312 for output, and the purpose of stroke amplification is achieved.

It should be noted that the movement stroke of the second traction rope 312 can be understood as: in the straightened state of the second traction rope 312, the free end of the second traction rope 312 moves along a stroke tangential to the second pulley 314. The movement stroke of the first traction rope 311 can be understood as follows: in the straightened state of the first traction rope 311, the free end of the first traction rope 311 moves along a stroke tangential to the first pulley 313.

In addition, a first limiting groove for stably winding the first traction rope 311 is formed on the first pulley 313, a second limiting groove for stably winding the second traction rope 312 is also formed on the second pulley 314, and the first limiting groove and the second limiting groove are not shown.

In some embodiments, the first pull-cord 311 extends along a first path K1. Specifically, first traction rope 311 extends along first path K1 when in a taut state and is coupled to drive assembly 100 so as to draw movement of first traction rope 311 along first path K1 as drive chamber 110 expands along first path K1, thereby fully translating the travel of drive chamber 110 along first path K1 into the travel of first traction rope 311.

In some embodiments, the driving assembly 100 includes a first case 130 and a driving plate 120 disposed within the first case 130. The driving plate 120 is connected to the pulley enlargement 310, the driving chamber 110 is located in a space defined by the driving plate 120 and the first casing 130, and the driving plate 120 is movable relative to the first casing 130 along a first path K1. It will be appreciated that the drive plate 120 is forced to move along the first path K1 relative to the first housing 130 when the drive chamber 110 is expanded, and the drive plate 120 is coupled to the first traction rope 311 in the pulley amplifying structure 310 to move the first traction rope 311. In addition, the displacement of the driving plate 120 moving along the first path K1 with respect to the first casing 130 is equal to the amount of the movement stroke when the driving chamber 110 expands along the first path K1.

Specifically, the first casing 130 extends along the first path K1 in a cylindrical shape, and the first casing 130 defines the expanding direction of the drive chamber 110 to the first path K1. It will be appreciated that the first housing 130 is capable of blocking the expansion of the drive chamber 110 to the periphery, thereby ensuring linkage between the drive plate 120 and the drive chamber 110, i.e., upon expansion of the drive chamber 110, the drive plate 120 is capable of moving along the first path K1, such that expansion of the drive chamber 110 is translated completely into movement of the drive plate 120, and likewise, reverse movement of the drive plate 120 is translated completely into contraction of the drive chamber 110.

Specifically, the first traction rope 311 is coupled to a central portion of the driving plate 120. It will be understood that "the center position of the drive plate 120" is the geometric center position of the plane in which the drive plate 120 lies, e.g., for a rectangular or square drive plate 120, the center position is at the intersection of the diagonals; for a circular drive plate 120, the center position is the center of the circle; for an irregularly shaped drive plate 120, the center position is at the center of gravity of the drive plate 120. Since the driving plate 120 moves along the first path K1 in the space defined by the first casing 130, the driving plate 120 can transmit the force to the first traction rope 311 and smoothly transmit the force from the first traction rope 311 after the fluid driving force of the driving chamber 110 acts on the driving plate 120. At the same time, since the first traction rope 311 extends along the first path K1, the first traction rope 311 is also allowed to obtain the maximum driving force from the driving chamber 110 to drive the first pulley 313 to rotate.

In some embodiments, the first tank 130 has a liquid inlet 131, the liquid inlet 131 is connected to the driving chamber 110, and the supply source injects the fluid into the driving chamber 110 through the liquid inlet 131. Specifically, the liquid inlet 131 is higher than the driving plate 120 in the vertical direction. It will be appreciated that the inlet 131 is in the upper position and the drive plate 120 is in the lower position, such that after the fluid is injected into the drive chamber 110 from the supply source, the gravity and impact of the fluid can act on the drive plate 120 to force the drive plate 120 to move relative to the first housing 130, thereby further transmitting the driving action from the drive plate 120 to the driven plate via the transmission assembly 300 to achieve the retraction of the driven chamber 210. It can be understood that even if the impact force of the fluid is weak, the fluid can provide a large driving force in cooperation with the gravity of the fluid, so that the fluid is discharged from the driving chamber 210 to realize effective flushing of the body in the sanitary ware.

In the embodiment shown in fig. 1, the driving assembly 100 further includes a first flexible sleeve 140 with two open ends, one end of the first flexible sleeve 140 is hermetically connected to the periphery of the driving plate 120, and the other end is hermetically connected to the inner wall of the first casing 130, so that the driving plate 120, the first flexible sleeve 140 and the first casing 130 cooperate to define the driving chamber 110 with a variable space size. Specifically, the first flexible sleeve 140 is a bellows that can be expanded or contracted. In other embodiments, the first flexible sleeve 140 may also be a soft rubber sleeve that can be flipped. In other embodiments, the first flexible sleeve 140 may be replaced by a first flexible bag connected to the first box 130, the inner cavity of the first flexible bag is the driving chamber 110, and the opening of the first flexible bag is correspondingly communicated with the liquid inlet 131. In other embodiments, the periphery of the driving plate 120 may flexibly abut against the inner sidewall of the first casing 130, so that the driving plate 120 moves relative to the first casing 130 and cooperates with the first casing 130 to form the driving chamber 110 with a variable space.

In some embodiments, gear enlargement 320 includes a transmission 321, a transmission rod 322, a transmission wheel 323, and a transmission gear 324. The transmission element 321 cooperates with a transmission wheel 323, and the transmission rod 322 engages with a transmission gear 324. The transmission wheel 323 is arranged coaxially with the transmission gear 324 and can rotate synchronously. The transmission member 321 is connected to the pulley amplifying structure 310, and the transmission rod 322 is connected to the driven assembly 200, such that during a flushing operation, the pulley amplifying structure 310 acts on the transmission member 321 to move, the transmission member 321 receives a stroke output of the pulley amplifying structure 310, and drives the transmission wheel 323 and the transmission gear 324 to rotate synchronously, and the transmission gear 324 further drives the transmission rod 322 to move to output a stroke to the driven cavity 210, so that the driven cavity 210 contracts along the second path K2.

Specifically, the diameter of the transmission gear 324 is larger than that of the transmission wheel 323, and the movement stroke of the transmission rod 322 is larger than that of the transmission member 321 when the transmission wheel rotates for a given angle. It can be understood that, during the synchronous rotation of the driving wheel 323 and the driving gear 324, the linear velocity of the driving rod 322 is greater than that of the driving member 321, so that the moving stroke of the driving rod 322 is greater than that of the driving member 321, and thus, the smaller stroke input to the driving member 321 in the gear amplifying structure 320 can be converted into the larger stroke of the driving rod 322 for output, and the purpose of stroke amplification is achieved.

In some embodiments, drive link 322 extends in a linear shape along second path K2. Specifically, the driving rod 322 extends along the second path K2 and is connected to the driven assembly 200, so that the driven cavity 210 can be forced to contract along the second path K2 when the driving rod 322 moves along the second path K2, thereby completely converting the movement stroke of the driving rod 322 along the second path K2 into the contraction stroke of the driven cavity 210 along the second path K2.

In some embodiments, the gear amplifying structure 320 includes a second guide 326, the transmission rod 322 extends in a long bar shape, and the second guide 326 is used for limiting the transmission rod 322 to a predetermined moving direction when the transmission rod 322 is engaged with and moves relative to the transmission gear 324, so that the transmission rod 322 can be ensured to move in the predetermined moving direction under the guiding action of the second guide 326, and the transmission rod 322 is prevented from being separated from the transmission gear 324 to cause the engagement failure.

In some embodiments, the driven assembly 200 includes a second case 230 and a driven plate 220 disposed within the second case 230. The driven plate 220 is connected to the gear amplifying structure 320, the driven chamber 210 is located in a space surrounded by the driven plate 220 and the second case 230, and the driven plate 220 can move relative to the second case 230 along the second path K2. It can be understood that when the gear amplifying structure 320 drives the driven plate 220 to move along the second path K2 relative to the second casing 230, the driven plate 220 can force the driven cavity 210 to contract, and the displacement of the driven plate 220 along the second path K2 relative to the second casing 230 is equal to the movement stroke amount of the driven cavity 210 along the second path K2.

Specifically, the second casing 230 extends in a cylindrical shape along the second path K2, and the second casing 230 defines the contraction direction of the driven chamber 210 to the second path K2. It is understood that the second casing 230 can block the expansion of the driven chamber 210 to the periphery, thereby ensuring the linkage between the driven plate 220 and the driven chamber 210, i.e., the contraction of the driven chamber 210 along the second path K2 can be completely converted when the driven plate 220 moves along the second path K2, and the expansion of the driven chamber 210 can be also completely converted into the movement of the driven plate 220.

Specifically, the driving lever 322 is connected to a central position of the driven plate 220. It is understood that the "center position of the driven plate 220" is the geometric center position of the plane in which the driven plate 220 is located, for example, in the case of a rectangular or square driven plate 220, the center position is at the intersection of the diagonal lines; for the circular driven plate 220, the center position thereof is the center of the circle; with the driven plate 220 of an irregular shape, the center position thereof is at the center of gravity of the driven plate 220. Since the driven plate 220 moves along the second path K2 in the space defined by the second case 230, it is possible for the driven plate 220 to smoothly transmit force to the driven chamber 210 along the second path K2 after the driving lever 322 acts on the driven plate 220. At the same time, since the driving lever 322 extends along the second path K2, the driven plate 220 is also allowed to obtain the maximum driving force from the driving lever 322 to force the driven cavity 210 to contract.

In some embodiments, in the transmission assembly 300, the transmission member 321 in the gear amplifying structure 320 is connected to the second traction rope 312 in the pulley amplifying structure 310, and the transmission member 321 extends in the same direction as the second traction rope 312, so that the force can be smoothly transmitted between the second traction rope 312 and the transmission member 321.

Specifically, in the embodiment shown in fig. 1, the transmission wheel 323 is a gear wheel, and the transmission member 321 is a rack engaged with the transmission wheel 323. The gear enlarging structure 320 includes a first guiding element 325, the transmission element 321 extends in a strip shape, and the first guiding element 325 is used for limiting the transmission element 321 to a predetermined moving direction when the transmission element 321 is engaged with the transmission wheel 323 and moves relatively. By providing the first guide 325, the moving direction of the transmission member 321 can be limited, and the pulley enlarging structure 310 can be ensured to smoothly act on the transmission member 321.

In the embodiment shown in fig. 2, the transmission wheel 323 is a pulley, and the transmission member 321 is a traction rope wound around the transmission wheel 323, so that the transmission member 321 can also smoothly receive the force of the pulley amplifying structure 310. Specifically, the transmission member 321 is coupled to the second traction rope 312 in the pulley amplifying structure 310. Since the transmission member 321 and the second traction rope 312 are flexible ropes, they can be integrated into a whole, i.e. one end of the rope is wound on the transmission wheel 323, and the other end is wound on the second pulley 314, at this time, the first guide member 325 can be omitted.

In some embodiments, the second casing 230 has a liquid outlet 231, the liquid outlet 231 is communicated with the driven cavity 210, and the fluid in the driven cavity 210 is discharged into the body of the sanitary ware through the liquid outlet 231, as shown in fig. 1.

In some embodiments, the second casing 230 has a fluid infusion port (not shown) formed thereon, the fluid infusion port is communicated with the driven chamber 210, and the supply source injects fluid into the driven chamber 210 through the fluid infusion port. Specifically, the fluid infusion port and the fluid discharge port 231 are provided at an interval. In other embodiments, the driven cavity 210 may also be replenished with fluid via the drain 231.

In the embodiment shown in fig. 1, the driven assembly 200 further includes a second flexible sleeve 240 with two open ends, one end of the second flexible sleeve 240 is hermetically connected to the periphery of the driven plate 220, and the other end is hermetically connected to the inner wall of the second housing 230, so that the driven plate 220, the second flexible sleeve 240 and the second housing 230 cooperate to define the driven cavity 210 with a variable space size. Specifically, the second flexible sleeve 240 is a corrugated tube that can be expanded or contracted. In other embodiments, the second flexible sleeve 240 may also be a soft rubber sleeve that can be turned over. In other embodiments, the second flexible sleeve 240 may be replaced by a second flexible bag connected to the second casing 230, the inner cavity of the second flexible bag is the driven cavity 210, and the opening of the second flexible bag is correspondingly communicated with the liquid outlet 231. In other embodiments, the periphery of the driven plate 220 flexibly abuts against the inner side wall of the second casing 230, so that the driven plate 220 moves relative to the second casing 230 and cooperates with the second casing 230 to form the driven cavity 210 with a variable space size.

In some embodiments, a washing waterway is formed inside the body, and fluid discharged from the liquid discharge port of the driven cavity can enter the washing waterway to flow from the upper side of the liquid storage tank to the liquid storage tank downwards, so that the inner wall of the liquid storage tank is uniformly washed from top to bottom. In addition, a spraying waterway is formed in the body, fluid discharged from a liquid outlet of the driven cavity can enter the spraying waterway, and enters the liquid pool under the guidance of the spraying waterway and is discharged by carrying dirt through the sewage discharging port. In addition, the sewage discharge port is connected with a siphon, and the siphon can suck the sewage and fluid in the liquid storage tank to facilitate the smooth discharge of the sewage in the liquid storage tank.

In some embodiments, the sanitary equipment comprises a regulation module, and the regulation module is used for regulating and controlling water injection or water drainage in the driving cavity and the driven cavity.

The regulation and control module comprises a first control valve, a control switch, a second control valve, a liquid level detection piece and a contraction detection piece. The control switch is connected with the first control valve to adjust the passage structure in the first control valve according to signals or operation. A second control valve is connected between the driven chamber and the fluid supply. The liquid level detection piece is arranged in the driven cavity and used for detecting the liquid level height in the driven cavity, and the second control valve switches the on-off of a flow channel between the driven cavity and the fluid supply source according to the feedback of the liquid level detection piece. The contraction detection piece is used for detecting the compression degree of the driven cavity, and the control switch is connected with the contraction detection piece and responds according to the feedback of the contraction detection piece.

Specifically, the first control valve is connected between the drive chamber and the fluid supply source, while also being connected between the drive chamber and the driven chamber. It will be appreciated that the first control valve has three ports, a first port in communication with the fluid supply, a second port in communication with the drive chamber, and a third port in communication with the driven chamber.

Before initiating a flushing operation, the drive chamber is in a contracted state. The liquid level in the driven cavity is located at a preset height, and according to the liquid level detection result of the liquid level detection piece, the second control valve blocks a passage between the driven cavity and the fluid supply source to prevent fluid from being supplemented into the driven cavity, and at the moment, a first through hole and a second through hole in the first control valve are blocked to prevent the fluid supply source from injecting fluid into the driving cavity.

When the flushing operation is started, the control switch is triggered to control the first control valve, so that the first port and the second port are communicated in the first control valve, the second port and the third port are cut off in the first control valve, namely, the fluid supply source is communicated with the driving cavity, and the driving cavity is isolated from the driven cavity. Fluid output by the fluid supply source is injected into the driving cavity through the first control valve, the driving cavity is gradually expanded, and the fluid in the driving cavity flows out of the washing water channel and the spraying water channel after passing through the liquid discharge port through transmission of the transmission assembly, so that the inner wall surface of the body is washed, and dirt at the sewage discharge port is washed away.

During the drainage of the driven cavity, the driven cavity gradually shrinks along with the injection of the fluid output by the fluid supply source into the driving cavity until the driven cavity shrinks to the maximum extent, and the drainage process of compressing the driven cavity is finished. At this time, the contraction detection member is triggered, and the contraction detection member triggers the control switch to reset. The reset of the control switch enables the first port and the second port to be blocked inside the first control valve, thereby blocking the fluid supply source from injecting fluid into the driving chamber, and enabling the first port and the third port to communicate, i.e., enabling the driving chamber and the driven chamber to communicate.

After the drainage of the driven cavity is finished, the residual fluid in the driven cavity forms thrust on the inner wall of the driven cavity under the action of the gravity of the driven cavity, so that the driven cavity is expanded. The expansion of the slave chamber causes the level of the liquid in the slave chamber to drop. When the liquid level in the driven cavity drops to be lower than the preset height value, the liquid level detection part triggers the second control valve, so that a passage between the driven cavity and a fluid supply source in the second control valve is opened, the fluid supply source continuously injects fluid into the driven cavity, and under the action of the fluid injected by the fluid supply source, the driven cavity is further expanded to force the driving cavity to shrink through the transmission assembly to discharge the fluid. At this time, the first port and the second port in the first control valve are blocked, the fluid supply source is prevented from injecting fluid into the driving cavity, and the first port and the third port are communicated, so that fluid discharged from the driving cavity enters the driven cavity, and therefore the driving cavity can also serve as a supply source in the driven cavity fluid replacement operation process. When the liquid level of the driven cavity reaches a preset height, the liquid supplementing operation of the driven cavity is completed, and the driving cavity is in a fully contracted state before the flushing operation is started.

It should be noted that the liquid level detection member is a float, which can float up with the rising of the liquid level in the driven cavity, and descend with the falling of the liquid level, and can float up and down along a specific direction, so that the valve port of the second control valve is accurately matched and blocked to block the communication between the driven cavity and the fluid supply source and the driving cavity when the liquid level rises and floats up, and the liquid level detection member can descend to open the valve port of the second control valve to realize the communication between the driven cavity and the fluid supply source and the driving cavity when the liquid level falls. In other embodiments, the liquid level detecting element may also be any one or more of a mechanical float, a hall sensor, a light sensor, a water pressure sensor, a current sensor, etc. that can assist in detecting or determining the height of the liquid level.

Specifically, the shrink detection piece is the trigger piece that sets up in the slave chamber, and the inner wall shrink of slave chamber is out of shape to can be when shrink to the at utmost with shrink detection piece looks butt, make shrink detection piece further act on control switch, control switch is used in the case of first control valve mechanically or automatically controlled ground, thereby makes the case switch the intercommunication between the three ports on with the valve body of first control valve. In addition, the control switch can be operated or reset through manually operating a button or a handle on the control switch.
