The utility model provides a sanitary ware (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.

Referring to fig. 1 and 2, in particular, 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. The transmission assembly 300 performs a force transmission function between the driving assembly 100 and the driven assembly 200, such that when the driving chamber 110 is forced to expand along the first preset direction K1, the driving chamber 110 can drive the transmission assembly 300 to move, such that the transmission assembly 300 forces the driven chamber 210 to contract along the second preset direction K2 and discharge fluid.

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 empty the drive chamber 110 in advance to bring the drive chamber 110 into a contracted state, as shown in fig. 1. 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 preset direction K1 due to the filling fluid, and the expansion of the driving chamber 110 causes the driven chamber 210 to contract along the second preset direction K2 under the driving action of the transmission 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 dirt from the dirt discharge port, that is, to implement a washing operation, as shown in fig. 2.

In order to maintain the flushing mechanism 10 to perform multiple flushing functions, after a single flushing operation is completed, the driven chamber 210 needs to be replenished with fluid by using a supply source capable of generating a driving external force, the driven chamber 210 expands in a direction opposite to the second preset direction K2 due to fluid filling, and the transmission assembly 300 is driven to move so as to force the driving chamber 110 to contract in a direction opposite to the first preset direction K1, so that the fluid in the driving chamber 110 is discharged, that is, the fluid replenishing operation of the driven chamber 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 the drive chamber, rather than through the transmission assembly.

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.

Referring to fig. 1 and 2, in some embodiments, the driving assembly 300 includes a driving member 310 connected to the driving assembly 100, a driving rod 320 connected to the driven assembly 200, a driving wheel 330 engaged with the driving member 310, and a driving gear 340 engaged with the driving rod 320, wherein the driving wheel 330 is coaxially disposed with the driving gear 340 and can rotate synchronously. When the driving cavity 110 is stressed to expand along the first preset direction K1, the driving cavity 110 can drive the transmission member 310 to move, the transmission member 310 can drive the transmission wheel 330 and the transmission gear 340 to rotate synchronously, the transmission gear 340 drives the transmission rod 320 to move so as to force the driven cavity 210 to contract along the second preset direction K2 and discharge fluid, and the stroke amount of the contraction of the driven cavity 210 along the second preset direction K2 is greater than the stroke amount of the expansion of the driving cavity 110 along the first preset direction K1, so that the space variation of the driven cavity 210 is greater than the space variation of the driving cavity 110.

It is understood that the "amount of spatial variation of the driven chamber 210" is the amount of spatial contraction of the driven chamber 210 when contracting in the second predetermined direction K2, and it is understood that the amount of spatial reduction of the driven chamber 210 when contracting, i.e. the volume of the fluid discharged from the driven chamber 210. The "amount of spatial variation of the driving chamber 110" is the amount of spatial expansion of the driving chamber 110 when expanding along the first preset direction K1, and it can be understood that the amount of spatial expansion of the driving chamber 110 when expanding, that is, the volume of the fluid replenished by the driving chamber 110.

"the amount of change in the space of the driven chamber 210 is greater than the amount of change in the space of the driving chamber 110" indicates that the volume of the fluid discharged from the driven chamber 210 is greater than the volume of the fluid replenished from the driving chamber 110, and since the changes in the spaces of the driven chamber 210 and the driving chamber 110 are synchronized, it means that the changes in the spaces are performed in the same period of time, and thus it can be obtained: the volume of fluid displaced from the drive chamber 210 per unit time is greater than the volume of fluid replenished by the drive chamber 110, i.e., the flow rate of fluid displaced from the drive chamber 210 is greater than the flow rate of fluid replenished by the drive chamber 110.

It should be noted that the specific meaning of the above-mentioned "the stroke amount of the driven cavity 210 contracting along the second preset direction K2 is greater than the stroke amount of the driving cavity 110 expanding along the first preset direction K1, so that the space variation amount of the driven cavity 210 is greater than the space variation amount of the driving cavity 110" is: the "amount of change in the space of the driven chamber 210 is greater than the amount of change in the space of the driving chamber 110" is determined by taking "the amount of stroke of the driven chamber 210 in the second preset direction K2 is greater than the amount of stroke of the driving chamber 110 in the first preset direction K1" as a leading factor, i.e., the influence of the size relationship between the sectional area of the driven chamber 210 and the sectional area of the driving chamber 110 on the difference in the amount of change in the space of the driven chamber 210 and the driving chamber 110 is not considered.

It will be appreciated that when the driven chamber 210 has a cross-sectional area equal to the cross-sectional area of the drive chamber 110; alternatively, when the sectional area of the driven chamber 210 is slightly larger than the sectional area of the driving chamber 110; or, even if the average cross-sectional area S2 of the cross-section of the driven chamber 210 is smaller than the average cross-sectional area S1 of the cross-section of the driving chamber 110, as long as the degree of the amount of the stroke of the driven chamber 210 contracting in the second preset direction K2 is sufficiently greater than the amount of the stroke of the driving chamber 110 expanding in the first preset direction K1, and the negative effect caused by the smaller average cross-sectional area of the cross-section of the driven chamber 210 can be offset; in the foregoing three cases, it can be ensured that the amount of spatial variation of the driven cavity 210 is greater than the amount of spatial variation of the driving cavity 110, and at this time, the amount of spatial variation of the driven cavity 210 is greater than the amount of spatial variation of the driving cavity 110, mainly based on the fact that "the stroke amount of the driven cavity 210 contracting along the second preset direction K2 is greater than the stroke amount of the driving cavity 110 expanding along the first preset direction K1".

In the flushing mechanism 10, the transmission assembly 300 is provided, so that the transmission member 310, the transmission rod 320, the transmission wheel 330 and the transmission gear 340 in the transmission assembly 300 act together, and the transmission of the acting force between the driving chamber 110 and the driven chamber 210 can be realized. Further, through the transmission effect of the transmission assembly 300, the stroke amplification effect can be achieved, the stroke amount of the driven cavity 210 contracting along the second preset direction K2 is greater than the stroke amount of the driving cavity 110 expanding along the first preset direction K1, so that the purpose that the space variation amount of the driven cavity 210 is greater than the space variation amount of the driving cavity 110 is achieved, and thus, the flow rate of the fluid discharged from the driven cavity 210 is greater than the flow rate of the fluid supplemented by the driving cavity 110, and therefore, under the condition that the flow rate of a supply source is small, the fluid discharged from the driven cavity 210 can have a large flow rate, the flushing requirement of the sanitary ware is met, and a good flushing effect is achieved. 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 drive assembly 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 diameter of the drive wheel 330 is less than the diameter of the drive gear 340. Because the diameter of the driving wheel 330 is smaller than that of the transmission gear 340, when the driving wheel 330 and the transmission gear 340 rotate synchronously, the linear velocity of the driving wheel 330 is smaller than that of the transmission gear 340, so that the moving stroke of the transmission member 310 matched with the driving wheel 330 is smaller than that of the transmission rod 320 meshed with the transmission gear 340, thereby realizing the amplification of the moving stroke of the transmission rod 320, further converting the smaller stroke amount when the driving cavity 110 expands into the larger stroke amount when the driven cavity 210 contracts, and further achieving the purpose of amplifying the stroke amount.

In some embodiments, the transmission member 310 extends in the first predetermined direction K1. The transmission lever 320 extends in a second preset direction K2. In this way, the driving member 310 can be moved along the first predetermined direction K1 by extending along the first predetermined direction K1 after being engaged with the driving wheel 330, and the driving rod 320 can be moved along the second predetermined direction K2 by extending along the second predetermined direction K2 after being engaged with the driving gear 340. In this way, the stroke amount of the driving cavity 110 during expansion is completely converted into the moving stroke of the transmission member 310, and the moving stroke of the transmission rod 320 is completely converted into the stroke amount of the driven cavity 210 during contraction, so that the complete conversion from the stroke amount of the driving cavity 110 during expansion to the stroke amount of the driven cavity 210 during contraction is realized, and the conversion efficiency is improved.

It should be noted that, when the transmission member 310 moves along the first predetermined direction K1, the "stroke amount when the driving cavity 110 expands is equal to the moving stroke of the transmission member 310", so that the transmission member 310 has the maximum moving stroke. In addition, since the ratio of the "moving stroke of the transmission member 310" to the "moving stroke of the transmission rod 320" is the transmission ratio of the transmission wheel 330 to the transmission gear 340, and the transmission ratio is a fixed value, when the transmission member 310 has the maximum moving stroke, the transmission rod 320 also has the maximum moving stroke. Further, when the transmission rod 320 moves along the second predetermined direction K2, the "moving stroke of the transmission rod 320 is equal to the stroke amount of the driven cavity 210 when it contracts", so that the maximum moving stroke of the transmission rod 320 can be completely converted into the stroke amount of the driven cavity 210 when it contracts, and the driven cavity 210 reaches the maximum contraction stroke amount. In this way, the maximum conversion of the stroke amount when the driving chamber 110 expands to the stroke amount when the driven chamber 210 contracts is achieved.

In some embodiments, flush mechanism 10 includes a tank 400. It is understood that the case 400 has a hollow structure and has a receiving space capable of receiving each component. The driving assembly 100 includes a driving plate 120 accommodated in a casing 400 and capable of moving along a first predetermined direction K1, and the driving cavity 110 is located in a space enclosed by the driving plate 120 and the casing 400. The driven assembly 200 includes a driven plate 220 accommodated in the box 400 and capable of moving along the second predetermined direction K2, and the driven cavity 210 is located in a space enclosed by the driven plate 220 and the box 400. The transmission assembly 300 is located in the box 400 and connected between the driving plate 120 and the driven plate 220, so that when the driving cavity 110 is expanded by a force, the driving plate 120, the transmission assembly 300 and the driven plate 220 sequentially transmit the force, and finally the driven cavity 210 is contracted. Because the driving assembly 100, the driven assembly 200 and the transmission assembly 300 are all located in the box 400, the whole flushing mechanism 10 can be taken as an integral module, so that the flushing mechanism 10 can be quickly disassembled and assembled, and the disassembling and assembling efficiency of the flushing mechanism 10 is improved.

In addition, the first predetermined direction K1 is consistent with the second predetermined direction K2, and the driving chamber 110, the transmission assembly 300, and the driven chamber 210 are linearly arranged in the box 400. It is understood that when the first predetermined direction K1 coincides with the second predetermined direction K2, the driving chamber 110, the transmission assembly 300, and the driven chamber 210 may be sequentially arranged in a "U" shape, or may be linearly arranged. Compared with the arrangement mode of the U-shaped structure, the arrangement mode of the three components is limited to be linear arrangement, the compactness among the driving cavity 110, the driven cavity 210 and the transmission assembly 300 can be further improved, and the box body 400 with smaller volume can accommodate all the components.

In the embodiment shown in fig. 1, the box 400 extends in a cylindrical shape, the space inside the box 400 is roughly divided into three parts by the driving plate 120 and the driven plate 220, the driving chamber 110 is located at one end inside the box 400, the driven chamber 210 is located at the other end inside the box 400, and the transmission assembly 300 is located in the middle area inside the box 400, so that the driving chamber 110, the transmission assembly 300, and the driven chamber 210 are linearly arranged along the extending direction of the box 400.

Further, as shown in fig. 1 and fig. 2, for the transmission assembly, the transmission wheel 330 may be a gear, and in this case, the transmission member 310 is a rack capable of engaging with the transmission wheel 330, so that the transmission member 310 and the transmission rod 320 are both in a bar-shaped structure. For the linear arrangement of the driving chamber 110, the driving assembly 300, and the driven chamber 210, the driving member 310 and the driving rod 320 can be disposed on two sides or the same side of the driving wheel 330, and when the driving member 310 and the driving rod 320 are disposed on the same side of the driving wheel 330, the overall layout is more compact, and the volume of the box 400 can be further reduced.

In the embodiment shown in fig. 3, the driving wheel 330 is a pulley, and the driving member 310 is a traction rope wound around the driving wheel 330, so that the driving assembly 100 and the driven assembly 200 can be linked.

In some embodiments, the transmission member 310 is attached to a central location of the drive plate 120, as shown in fig. 1 and 2. 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 in the first predetermined direction K1 in the space defined by the casing 400, the driving plate 120 can transmit the driving force to the transmission member 310 and can be smoothly transmitted by the transmission member 310 after the fluid driving force of the driving chamber 110 acts on the driving plate 120. At the same time, since the transmission member 310 extends along the first predetermined direction K1, the transmission member 310 obtains the maximum driving force from the driving chamber 110 to drive the transmission wheel 330 to rotate.

In other embodiments, the driving rod 320 may be connected to the center of the driven plate 220, so that when the driving assembly 300 pushes the driven plate 220 to move and force the driven cavity 210 to retract, the driving rod 320 can provide a smooth acting force to the driven plate 220, thereby achieving a smooth retraction of the driven cavity 210 and achieving a more stable flushing effect.

In some embodiments, the housing 400 is opened with an air hole 410, and the air hole 410 is specifically located on the region between the driving plate 120 and the driven plate 220. It can be understood that, after the space in the box 400 is removed from the space occupied by the driving chamber 110 and the driven chamber 210, the remaining space is expanded along with the expansion of the driving chamber 110 and the contraction of the driven chamber 210 (i.e. during the flushing operation), and is reduced along with the contraction of the driving chamber 110 and the expansion of the driven chamber 210 (i.e. during the fluid infusion operation of the driven chamber 210), and the air holes 410 are provided to facilitate air intake when the remaining space is expanded and air exhaust when the remaining space is reduced, thereby achieving smooth performance of the flushing operation and the fluid infusion operation.

In some embodiments, the tank 400 has a loading port 420, the loading port 420 is connected to the driving chamber 110, and the supply source injects fluid into the driving chamber 110 through the loading port 420.

In the embodiment shown in fig. 1, the driving assembly 100 further includes a first flexible bag 130, the first flexible bag 130 is accommodated in a space enclosed by the driving plate 120 and the box 400, at this time, an inner cavity of the first flexible bag 130 is the driving chamber 110, and an opening of the first flexible bag 130 is correspondingly communicated with the liquid inlet 420. Further, a gap exists between the driving plate 120 and the box 400, so that the driving plate 120 is prevented from colliding with the inner wall of the box 400 to generate friction when moving in the box 400, and the driving plate 120 is ensured to move smoothly in the box 400. In other embodiments, the first flexible bag 130 may be replaced by a first flexible sleeve with two open ends, one end of the first flexible sleeve is hermetically connected to the periphery of the driving plate 120, and the other end of the first flexible sleeve is hermetically connected to the inner wall of the case 400, so that the driving plate 120, the first flexible sleeve and the case 400 cooperate to define the driving cavity 110 with a variable space size. The first flexible sleeve can be a soft rubber sleeve or a deformable corrugated pipe. In other embodiments, the periphery of the driving plate 120 may flexibly abut against the inner sidewall of the casing 400, so that the driving plate 120 moves relative to the casing 400 and cooperates with the casing 400 to form the driving chamber 110 with a variable space size.

In some embodiments, the tank 400 is provided with a drain port 430, the drain port 430 is communicated with the driven chamber 210, and the fluid in the driven chamber 210 is discharged into the body of the sanitary ware through the drain port 430, as shown in fig. 1.

In some embodiments, the tank 400 has a fluid infusion port (not shown) formed therein, the fluid infusion port communicates 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 430 are provided at an interval. In other embodiments, the driven cavity 210 may also be replenished with fluid via the drain 430.

In the embodiment shown in fig. 1, the driven assembly 200 further includes a second flexible bag 230, the second flexible bag 230 is accommodated in a space enclosed by the driven plate 220 and the box 400, at this time, an inner cavity of the second flexible bag 230 is the driven cavity 210, and an opening of the second flexible bag 230 is correspondingly communicated with the liquid discharge port 430. Further, a gap is formed between the driven plate 220 and the box 400, so that the driven plate 220 is prevented from colliding with the inner wall of the box 400 to generate friction when moving in the box 400, and the driven plate 220 is ensured to move smoothly in the box 400. In other embodiments, the second flexible bag 230 may be replaced by a second flexible sleeve with two open ends, one end of the second flexible sleeve is connected to the periphery of the driven plate 220 in a sealing manner, and the other end of the second flexible sleeve is connected to the inner wall of the box 400 in a sealing manner, so that the driven plate 220, the second flexible sleeve and the box 400 cooperate to define the driven cavity 210 with a variable space size. The second flexible sleeve can be a soft rubber sleeve or a deformable corrugated pipe. In other embodiments, the periphery of the driven plate 220 may flexibly abut against the inner side wall of the box 400, so that the driven plate 220 moves relative to the box 400 and cooperates with the box 400 to form the driven cavity 210 with variable space.

In the embodiment shown in fig. 1, the average cross-sectional area of the cross-section of the driven chamber 210 is equal to the average cross-sectional area of the cross-section of the driving chamber 110.

It is understood that the "cross section of the driving chamber 110" means a section taken by making a plane perpendicular to the first predetermined direction K1 and cutting the driving chamber 110 with the plane. Since there are many planes perpendicular to the first predetermined direction K1, there are many cross sections obtained after the planes cut the driving chamber 110, and the average cross section is obtained after the areas of all the cross sections are summed. 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.

It should be understood that, similarly, the "cross section of the driven cavity 210" refers to a plane perpendicular to the second predetermined direction K2, and a section obtained by cutting the driven cavity 210 with the plane is a plurality of planes perpendicular to the second predetermined direction K2, so that a plurality of sections are obtained after the planes cut the driven cavity 210, and the average value after the areas of all the sections are summed is the average sectional area. 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.

With reference to fig. 1 and fig. 2, the average cross-sectional area of the cross-section of the driving chamber 110 is set to be S1, the average cross-sectional area of the cross-section of the driven chamber 210 is set to be S2, the amount of change in the space of the driving chamber 110 is set to be V1, the amount of change in the space of the driven chamber 210 is set to be V2, the driving chamber 110 expands from the state shown in fig. 1 to the state shown in fig. 2 along the first preset direction K1, the stroke amount of the driving chamber 110 is set to be H1, the driven chamber 210 contracts from the state shown in fig. 1 to the state shown in fig. 2, and the stroke amount of the driven chamber 210 contracts along the second preset direction K2 is set to be H2, and the following relationships exist: v1 ═ S1 × H1, V2 ═ S2 × H2.

When the average cross-sectional area S1 of the cross-section of the driving chamber 110 is substantially equal to the average cross-sectional area S2 of the cross-section of the driven chamber 210, the amount of change V2 in the space of the driven chamber 210 is only positively correlated with the amount of contraction H2 of the driven chamber 210 in the second preset direction K2, and the amount of change V1 in the space of the driving chamber 110 is only positively correlated with the amount of expansion H1 of the driving chamber 110 in the first preset direction K1, so that "the amount of contraction H2 of the driven chamber 210 in the second preset direction K2 is greater than the amount of expansion H1 of the driving chamber 110 in the first preset direction K1" inevitably makes the amount of change V2 in the space of the driven chamber 210 greater than the amount of change V1 in the space of the driving chamber 110 ", so as to achieve the purpose of making the flow rate of the fluid discharged from the driven chamber 210 greater than the flow rate of the fluid supplemented by the driving chamber 110, thereby achieving the first-stage amplification of the flow rate of the discharged fluid.

In other embodiments, in the case that the stroke amount H2 of the driven chamber 210 contracting in the second preset direction K2 is greater than the stroke amount H1 of the driving chamber 110 expanding in the first preset direction K1, if the average cross-sectional area S2 of the cross-section of the driven chamber 210 is further greater than the average cross-sectional area S1 of the cross-section of the driving chamber 110, the degree that the "amount of change V2 of the driven chamber 210 is greater than the" amount of change V1 "of the space of the driving chamber 110" is further enlarged, so that the flow rate of the fluid discharged from the driven chamber 210 is further increased, and the two-stage enlargement of the flow rate of the discharged fluid is realized.

In other embodiments, in the case that the stroke amount H2 of the driven chamber 210 contracting in the second preset direction K2 is greater than the stroke amount H1 of the driving chamber 110 expanding in the first preset direction K1, "the amount of change V2 in the driven chamber 210 is greater than the amount of change V1 in the driving chamber 110", so that the one-step amplification of the flow rate of the discharged fluid is realized. On the basis, if there are a plurality of slave cavities 210, the plurality of slave cavities 210 can be synchronously contracted along the second predetermined direction K2. It will be appreciated that the drive assembly 300 is capable of simultaneously acting on a plurality of slave cavities 210 to simultaneously retract a plurality of slave cavities 210. Therefore, on the basis that the amount of spatial variation V2 of the single driven chamber 210 is larger than the amount of spatial variation V1 of the driving chamber 110, the extent to which the sum of the amounts of spatial variation V2 of the plurality of driven chambers 210 is larger than the amount of spatial variation V1 of the driving chamber 110 is further amplified, thereby further increasing the flow rate of the discharged fluid, and realizing the secondary amplification of the flow rate of the discharged fluid.

It should be noted that the arrangement of the plurality of driven cavities 210 is not specifically set, and may be in a linear or circumferential or array arrangement. In addition, in other embodiments, it is also possible to further make the average sectional area S2 of the cross section of the driven chamber 210 larger than the average sectional area S1 of the cross section of the driving chamber 110 while setting the driven chamber 210 in plurality in case that the stroke amount H2 by which the driven chamber 210 contracts in the second preset direction K2 is larger than the stroke amount H1 by which the driving chamber 110 expands in the first preset direction K1, thus achieving three-stage amplification of the flow rate of the discharged fluid.

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.
