Flushing mechanism and bathroom equipment

Abstract

The present invention relates to a flushing mechanism and bathroom equipment. In the flushing mechanism, by setting a transmission component, the force transmission between the driving chamber and the driven chamber can be realized to play a role in stroke amplification, so that the stroke amount of the driven chamber contracting along the second preset direction is greater than the stroke amount of the driving chamber expanding along the first preset direction, thereby achieving the purpose of making the spatial variation of the driven chamber greater than the spatial variation of the driving chamber. In this way, the flow rate of the fluid discharged from the driven chamber can be greater than the flow rate of the fluid supplemented by the driving chamber, so that when the flow rate of the supply source is small, the fluid discharged from the driven chamber can also have a large flow rate, thereby meeting the flushing needs of the bathroom equipment and achieving a better flushing effect. The above effect can be achieved by only making a reasonable layout of the flushing structure and setting a low-cost transmission component. Compared with the additional setting of an expensive booster pump, the flushing mechanism of the present application has a lower cost.

Description

Technical Field

[0001] The invention relates to the technical field of bathroom products, and in particular to a flushing mechanism and bathroom equipment. Background Art

[0002] Bathroom equipment often needs to be injected with water after use to clean the inner wall or flush away dirt. For example, a toilet needs to be flushed with water after use to clean or flush away dirt. The greater the injected water flow rate (i.e., the amount of water injected per unit time), the cleaner the toilet is flushed.

[0003] However, some bathroom equipment usually uses tap water directly for flushing. Since the water pressure of tap water often fluctuates, the water flow rate fluctuates, and the cleanliness of flushing cannot be guaranteed. Some bathroom equipment also chooses to install a booster pump to ensure the water flow rate, but this method will increase the manufacturing cost of the entire equipment. Summary of the invention

[0004] Based on this, it is necessary to provide a flushing mechanism with low cost and capable of ensuring a large water flow rate, and also provide a bathroom equipment.

[0005] A flushing mechanism, comprising:

[0006] A driving assembly having a driving cavity with a variable size for accommodating a fluid;

[0007] A driven component having a driven cavity for accommodating a fluid and having a variable space size; and

[0008] A transmission assembly comprises a transmission member connected to the driving assembly, a transmission rod connected to the driven assembly, a transmission wheel matched with the transmission member, and a transmission gear meshed with the transmission rod; the transmission wheel and the transmission gear are coaxially arranged and can rotate synchronously; the driving chamber is forced to expand along a first preset direction to drive the transmission member to move, the transmission member drives the transmission wheel and the transmission gear to rotate, and the transmission gear drives the transmission rod to move and forces the driven chamber to contract along a second preset direction to discharge fluid, and the contraction stroke of the driven chamber along the second preset direction is greater than the expansion stroke of the driving chamber along the first preset direction, so that the spatial change of the driven chamber is greater than the spatial change of the driving chamber.

[0009] In the above flushing mechanism, by setting a transmission assembly, the transmission member, transmission rod, transmission wheel and transmission gear in the transmission assembly work together to realize the force transmission between the driving chamber and the driven chamber. Further, through the transmission action of the transmission assembly, it can also play a role of stroke amplification, so that the stroke amount of the driven chamber contracting along the second preset direction is greater than the stroke amount of the driving chamber expanding along the first preset direction, so as to achieve the purpose of making the spatial variation of the driven chamber greater than the spatial variation of the driving chamber, so that the flow rate of the fluid discharged from the driven chamber can be greater than the flow rate of the fluid supplemented by the driving chamber, so that when the flow rate of the supply source is small, the fluid discharged from the driven chamber can also have a large flow rate, thereby meeting the flushing needs of the bathroom equipment and achieving a better flushing effect. In addition, since the driven chamber will be filled with fluid in advance, it can ensure that the fluid discharged from the driven chamber has a large flow rate each time the flushing operation is performed. In addition, it only needs to reasonably layout the flushing structure and set a low-priced transmission assembly to achieve the above effect. Compared with the additional high-priced booster pump, the flushing mechanism of the present application has a low cost.

[0010] In one embodiment, the diameter of the transmission wheel is smaller than the diameter of the transmission gear.

[0011] In one embodiment, the transmission member extends along the first preset direction; and the transmission rod extends along the second preset direction.

[0012] In one embodiment, the flushing mechanism includes a housing; the driving assembly includes a driving plate accommodated in the housing and capable of moving along the first preset direction, and the driving cavity is located in the space enclosed by the driving plate and the housing; the driven assembly includes a driven plate accommodated in the housing and capable of moving along the second preset direction, and the driven cavity is located in the space enclosed by the driven plate and the housing; the transmission assembly is located in the housing and connected between the driving plate and the driven plate.

[0013] In one embodiment, the first preset direction is consistent with the second preset direction, and the driving cavity, the transmission assembly, and the driven cavity are linearly arranged in the housing along the first preset direction.

[0014] In one embodiment, the transmission wheel is a gear, the transmission member is a rack that can mesh with the transmission wheel, and the transmission member and the transmission rod are both located on the same side of the transmission wheel; or,

[0015] The transmission wheel is a pulley, and the transmission member is a traction rope wound on the transmission wheel.

[0016] In one embodiment, the transmission member is connected to the center of the driving plate.

[0017] In one embodiment, an air hole is formed on the box body in a region between the driving plate and the driven plate.

[0018] In one embodiment, the average cross-sectional area of ​​the cross section of the driven cavity is greater than the average cross-sectional area of ​​the cross section of the driving cavity; and / or,

[0019] There are multiple driven chambers, and the multiple driven chambers can shrink synchronously along the second preset direction.

[0020] A bathroom device comprises the above-mentioned flushing mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time.

[0030] The present invention provides a bathroom device (not shown), which includes a flushing mechanism and a body connected to the flushing mechanism. Specifically, the body is recessed to form a liquid reservoir, and a sewage outlet is provided on the bottom wall of the liquid reservoir. The flushing mechanism can discharge fluid and output the fluid to the inner wall surface of the liquid reservoir or the sewage outlet to flush the inner wall of the liquid reservoir and discharge the dirt from the sewage outlet. The bathroom device can be a toilet, a wash basin, a bathtub, and other equipment that needs to be flushed.

[0031] Combination Figure 1 and Figure 2As shown, 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 size. The driven assembly 200 has a driven chamber 210 for accommodating fluid and having a variable space size. The transmission assembly 300 plays a role in transmitting force between the driving assembly 100 and the driven assembly 200, so 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, so that the transmission assembly 300 forces the driven chamber 210 to contract along the second preset direction K2 and discharge the fluid.

[0032] It should be noted that in the above flushing mechanism 10, it is necessary to inject fluid into the driven chamber 210 in advance to fully expand the internal space of the driven chamber 210, and at the same time, the driving chamber 110 is emptied in advance to put the driving chamber 110 in a contracted state. Figure 1 When performing a flushing operation, a supply source capable of generating a driving external force injects fluid into the contracted driving chamber 110, and the driving chamber 110 expands along a first preset direction K1 due to the filling of the fluid. Under the transmission action of the transmission assembly 300, the expansion of the driving chamber 110 causes the driven chamber 210 to contract along a second preset direction K2, so that the fluid in the driven chamber 210 is discharged. The fluid discharged from the driven chamber 210 is output to the body in the bathroom equipment to flush the inner wall of the liquid storage tank or discharge the dirt from the sewage outlet, that is, to achieve a flushing operation, such as Figure 2 shown.

[0033] In order to maintain the function of multiple flushing of the flushing mechanism 10, it is necessary to use a supply source that can generate a driving external force to replenish fluid into the driven chamber 210 after a flushing operation is completed. The driven chamber 210 expands in the direction opposite to the second preset direction K2 due to the fluid filling, and can drive the transmission component 300 to move and force the driving chamber 110 to contract in the direction opposite to the first preset direction K1, so that the fluid in the driving chamber 110 is discharged, that is, the fluid replenishment operation of the driven chamber 210 is realized. In this way, after the fluid replenishment operation of the driven chamber 210 is completed, the flushing operation can be performed again, thereby achieving the purpose of multiple flushing. In other embodiments, other structures can be additionally provided to achieve the contraction of the driving chamber instead of completing it through the transmission component.

[0034] It should be noted that the "supply source capable of generating a driving external force" may be the output of a municipal tap water pipeline, in which 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 a driving external force" may also be the output of a municipal tap water pipeline after a pressure pump, or may also be the external storage water of a bathroom device pumped out by an external pump body. In addition, the "supply source" that provides an expansion force to the driving chamber 110 during a flushing operation may be the same as or different from the "supply source" that provides an expansion force to the driven chamber 210 during a fluid replenishment operation.

[0035] Combination Figure 1 and Figure 2 As shown, in some embodiments, the transmission assembly 300 includes a transmission member 310 connected to the driving assembly 100, a transmission rod 320 connected to the driven assembly 200, a transmission wheel 330 matched with the transmission member 310, and a transmission gear 340 meshed with the transmission rod 320, wherein the transmission wheel 330 and the transmission gear 340 are coaxially arranged and can rotate synchronously. When the driving chamber 110 is forced to expand along the first preset direction K1, the driving chamber 110 can drive the transmission member 310 to move, and the transmission member 310 can drive the transmission wheel 330 and the transmission gear 340 to rotate synchronously, and the transmission gear 340 drives the transmission rod 320 to move, forcing the driven chamber 210 to contract along the second preset direction K2 and discharge the fluid, and the contraction stroke of the driven chamber 210 along the second preset direction K2 is greater than the expansion stroke of the driving chamber 110 along the first preset direction K1, so that the spatial variation of the driven chamber 210 is greater than the spatial variation of the driving chamber 110.

[0036] It can be understood that the above-mentioned “spatial variation of the driven chamber 210” is the spatial contraction amount of the driven chamber 210 when it contracts along the second preset direction K2, which can be understood as the spatial reduction amount of the driven chamber 210 when it contracts, that is, the volume of the fluid discharged from the driven chamber 210. The “spatial variation of the driving chamber 110” is the spatial expansion amount of the driving chamber 110 when it expands along the first preset direction K1, which can be understood as the spatial increase amount of the driving chamber 110 when it expands, that is, the volume of the fluid replenished by the driving chamber 110.

[0037] “The spatial change of the driven chamber 210 is greater than the spatial change of the driving chamber 110” means that the volume of the fluid discharged from the driven chamber 210 is greater than the volume of the fluid replenished in the driving chamber 110. Since the spatial changes of the driven chamber 210 and the driving chamber 110 are carried out synchronously, it means that the spatial changes are carried out in the same time period. In this way, it can be obtained that: in unit time, the volume of the fluid discharged from the driven chamber 210 is greater than the volume of the fluid replenished in the driving chamber 110, that is, the flow rate of the fluid discharged from the driven chamber 210 is greater than the flow rate of the fluid replenished in the driving chamber 110.

[0038] It should be pointed out that the specific meaning of the above-mentioned “the contraction stroke of the driven chamber 210 along the second preset direction K2 is greater than the expansion stroke of the driving chamber 110 along the first preset direction K1, so that the spatial variation of the driven chamber 210 is greater than the spatial variation of the driving chamber 110” is: taking “the contraction stroke of the driven chamber 210 along the second preset direction K2 is greater than the expansion stroke of the driving chamber 110 along the first preset direction K1” as the dominant factor to make “the spatial variation of the driven chamber 210 is greater than the spatial variation of the driving chamber 110”, that is, the influence of the size relationship between the cross-sectional area of ​​the driven chamber 210 and the cross-sectional area of ​​the driving chamber 110 on the difference in spatial variation between the driven chamber 210 and the driving chamber 110 is not considered.

[0039] It can be understood that when the cross-sectional area of ​​the driven chamber 210 is equal to the cross-sectional area of ​​the driving chamber 110; or, when the cross-sectional area of ​​the driven chamber 210 is slightly larger than the cross-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 contraction stroke of the driven chamber 210 along the second preset direction K2 is larger than the expansion stroke of the driving chamber 110 along the first preset direction K1 to a sufficient extent and can offset the negative impact of the smaller average cross-sectional area of ​​the cross section of the driven chamber 210; in the above three cases, it can be ensured that the spatial variation of the driven chamber 210 is larger than the spatial variation of the driving chamber 110. At this time, the spatial variation of the driven chamber 210 is larger than the spatial variation of the driving chamber 110 mainly due to the dominant factor that "the contraction stroke of the driven chamber 210 along the second preset direction K2 is larger than the expansion stroke of the driving chamber 110 along the first preset direction K1".

[0040] In the above flushing mechanism 10, by setting the transmission assembly 300, the transmission member 310, the transmission rod 320, the transmission wheel 330, and the transmission gear 340 in the transmission assembly 300 work together to realize the force transmission between the driving chamber 110 and the driven chamber 210. Further, through the transmission action of the transmission assembly 300, the stroke amplification effect can also be achieved, so that the stroke amount of the driven chamber 210 contracting along the second preset direction K2 is greater than the stroke amount of the driving chamber 110 expanding along the first preset direction K1, thereby achieving the purpose of making the spatial variation of the driven chamber 210 greater than the spatial variation of the driving chamber 110. In this way, the flow rate of the fluid discharged from the driven chamber 210 can be greater than the flow rate of the fluid supplemented by the driving chamber 110, so that when the flow rate of the supply source is small, the fluid discharged from the driven chamber 210 can also have a large flow rate, thereby meeting the flushing needs of the bathroom equipment and achieving a better flushing effect. In addition, since the driven chamber 210 is pre-filled with fluid, each time a flushing operation is performed, it is possible to ensure that the fluid discharged from the driven chamber 210 has a large flow rate. In addition, the above effect can be achieved by only making a reasonable layout of the flushing structure and setting a low-cost transmission assembly 300. Compared with setting up an additional expensive booster pump, the flushing mechanism 10 of the present application has a lower cost.

[0041] In some embodiments, the diameter of the transmission wheel 330 is smaller than the diameter of the transmission gear 340. Since the diameter of the transmission wheel 330 is smaller than the diameter of the transmission gear 340, when the transmission wheel 330 and the transmission gear 340 rotate synchronously, the linear velocity of the transmission wheel 330 is smaller than the linear velocity of the transmission gear 340, so that the moving stroke of the transmission member 310 matched with the transmission wheel 330 is smaller than the moving stroke of the transmission rod 320 meshed with the transmission gear 340, thereby achieving the amplification of the moving stroke of the transmission rod 320, and further converting the smaller stroke amount when the driving cavity 110 expands into the larger stroke amount when the driven cavity 210 contracts, thereby achieving the purpose of amplifying the stroke amount.

[0042] In some embodiments, the transmission member 310 extends along the first preset direction K1. The transmission rod 320 extends along the second preset direction K2. In this way, the transmission member 310 can extend along the first preset direction K1 after cooperating with the transmission wheel 330 and can move along the first preset direction K1, and the transmission rod 320 can extend along the second preset direction K2 after meshing with the transmission gear 340 and can move along the second preset direction K2. In this way, the stroke amount when the driving cavity 110 expands is completely converted into the movement stroke of the transmission member 310, and the movement stroke of the transmission rod 320 is completely converted into the stroke amount when the driven cavity 210 contracts, thereby achieving a complete conversion of the stroke amount when the driving cavity 110 expands to the stroke amount when the driven cavity 210 contracts, thereby improving the conversion efficiency.

[0043] It should be noted that, only when the transmission member 310 moves along the first preset direction K1, the "stroke amount when the driving chamber 110 expands = the movement stroke of the transmission member 310", and thus the transmission member 310 has the maximum movement stroke. In addition, since the ratio of the "movement stroke of the transmission member 310" to the "movement stroke of the transmission rod 320" is the transmission ratio of the transmission wheel 330 and the transmission gear 340, and the transmission ratio is a constant value, when the transmission member 310 has the maximum movement stroke, the transmission rod 320 also has the maximum movement stroke. Further, only when the transmission rod 320 moves along the second preset direction K2, the "movement stroke of the transmission rod 320 = the movement stroke amount when the driven chamber 210 contracts", so that the maximum movement stroke of the transmission rod 320 can be completely converted into the movement stroke amount when the driven chamber 210 contracts, so that the driven chamber 210 reaches the maximum contraction stroke amount. In this way, the maximum degree of conversion of the movement stroke amount when the driving chamber 110 expands to the movement stroke amount when the driven chamber 210 contracts is achieved.

[0044] In some embodiments, the flushing mechanism 10 includes a box body 400. It is understood that the interior of the box body 400 is a hollow structure and has a receiving space capable of accommodating various components. The driving assembly 100 includes a driving plate 120 accommodated in the box body 400 and capable of moving along a first preset direction K1, and the driving cavity 110 is located in the space surrounded by the driving plate 120 and the box body 400. The driven assembly 200 includes a driven plate 220 accommodated in the box body 400 and capable of moving along a second preset direction K2, and the driven cavity 210 is located in the space surrounded by the driven plate 220 and the box body 400. The transmission assembly 300 is located in the box body 400 and is connected between the driving plate 120 and the driven plate 220. In this way, when the driving cavity 110 is expanded by 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. Since the driving assembly 100 , the driven assembly 200 and the transmission assembly 300 are all located in the box body 400 , the entire flushing mechanism 10 can be used as an integral module to facilitate quick assembly and disassembly, thereby improving the assembly and disassembly efficiency of the flushing mechanism 10 .

[0045] In addition, the first preset direction K1 is consistent with the second preset direction K2, and the driving cavity 110, the transmission assembly 300, and the driven cavity 210 are arranged linearly in the box 400. It can be understood that when the first preset direction K1 is consistent with the second preset direction K2, the driving cavity 110, the transmission assembly 300, and the driven cavity 210 can be arranged in sequence in a "U" shape, or the three can be arranged linearly. Compared with the "U"-shaped arrangement, limiting the arrangement of the three to "linear arrangement" can further improve the compactness between the driving cavity 110, the driven cavity 210 and the transmission assembly 300, so that the smaller volume of the box 400 can accommodate various components.

[0046] In such Figure 1 In the illustrated embodiment, the housing 400 extends in a cylindrical shape, and the space inside the housing 400 is roughly divided into three parts by the driving plate 120 and the driven plate 220. The driving cavity 110 is located at one end of the housing 400, the driven cavity 210 is located at the other end of the housing 400, and the transmission assembly 300 is located in the middle area of ​​the housing 400. In this way, the driving cavity 110, the transmission assembly 300, and the driven cavity 210 are arranged linearly along the extension direction of the housing 400.

[0047] Furthermore, if Figure 1 and Figure 2 As shown, for the transmission assembly, the transmission wheel 330 can be a gear, and the transmission member 310 is a rack that can mesh with the transmission wheel 330. In this way, the transmission member 310 and the transmission rod 320 are both long rod-shaped structures. For the case where the driving chamber 110, the transmission assembly 300, and the driven chamber 210 are arranged linearly, the transmission member 310 and the transmission rod 320 can be placed on both sides or on the same side of the transmission wheel 330. When the transmission member 310 and the transmission rod 320 are located on the same side of the transmission wheel 330, it means that the entire layout is more compact, and the volume of the box 400 can be further reduced.

[0048] exist Figure 3 In the illustrated embodiment, the transmission wheel 330 is a pulley, and the transmission member 310 is a traction rope wound around the transmission wheel 330 . In this way, the linkage between the driving component 100 and the driven component 200 can also be achieved.

[0049] In some embodiments, the transmission member 310 is connected to the center of the driving plate 120. Figure 1 and Figure 2 As shown. It can be understood that the “center position of the driving plate 120” is the geometric center position of the plane where the driving plate 120 is located. For example, for a rectangular or square driving plate 120, its center position is the intersection of the diagonals; for a circular driving plate 120, its center position is the center of the circle; for an irregular driving plate 120, its center position is the center of gravity of the driving plate 120. Since the driving plate 120 moves along the first preset direction K1 in the space defined by the box body 400, after the fluid driving force of the driving chamber 110 acts on the driving plate 120, the driving plate 120 can transmit the driving force to the transmission member 310, and the transmission member 310 transmits it smoothly. At the same time, since the transmission member 310 extends along the first preset direction K1, the transmission member 310 also obtains the maximum driving force from the driving chamber 110 and drives the transmission wheel 330 to rotate.

[0050] In other embodiments, the transmission rod 320 can also be connected to the center position of the driven plate 220. In this way, when the transmission assembly 300 pushes the driven plate 220 to move and forces the driven chamber 210 to shrink, the transmission rod 320 can provide a smooth force on the driven plate 220, thereby achieving a smooth shrinkage of the driven chamber 210 and achieving a relatively stable flushing effect.

[0051] In some embodiments, the box body 400 is provided with air holes 410, which are specifically located in the area between the driving plate 120 and the driven plate 220. It can be understood that after the space occupied by the driving chamber 110 and the driven chamber 210 is removed from the space in the box body 400, the remaining space will expand with the expansion of the driving chamber 110 and the contraction of the driven chamber 210 (i.e., during the flushing operation), and will shrink with the contraction of the driving chamber 110 and the expansion of the driven chamber 210 (i.e., during the fluid replenishment operation of the driven chamber 210). By providing the air holes 410, it can be helpful to take in air when the remaining space expands and to let out air when the remaining space shrinks, thereby achieving smooth flushing and fluid replenishment operations.

[0052] In some embodiments, a liquid inlet 420 is provided on the box body 400 , and the liquid inlet 420 is in communication with the driving chamber 110 . The supply source injects fluid into the driving chamber 110 through the liquid inlet 420 .

[0053] exist Figure 1 In the illustrated embodiment, the drive assembly 100 further includes a first flexible bag 130, which is accommodated in the space enclosed by the drive plate 120 and the box body 400. At this time, the inner cavity of the first flexible bag 130 is the drive cavity 110, and the opening of the first flexible bag 130 is correspondingly connected to the liquid inlet 420. Further, there is a gap between the drive plate 120 and the box body 400 to prevent the drive plate 120 from colliding with the inner wall of the box body 400 when moving in the box body 400 to generate friction, thereby ensuring that the drive plate 120 moves smoothly in the box body 400. In other embodiments, the first flexible bag 130 can also be replaced by a first flexible sleeve with openings at both ends, one end of the first flexible sleeve is sealed to the periphery of the drive plate 120, and the other end is sealed to the inner wall of the box body 400. In this way, the drive plate 120, the first flexible sleeve and the box body 400 cooperate to enclose the drive cavity 110 with a variable space size. The first flexible sleeve can be a soft rubber sleeve or a deformable bellows. In other embodiments, the periphery of the driving plate 120 may be flexibly in contact with the inner wall of the box 400 , so that the driving plate 120 moves relative to the box 400 and cooperates with the box 400 to enclose a driving cavity 110 with a variable space size.

[0054] In some embodiments, a drain port 430 is provided on the box body 400, and the drain port 430 is connected to the driven chamber 210, and the fluid in the driven chamber 210 is discharged into the body of the bathroom device through the drain port 430. Figure 1 shown.

[0055] In some embodiments, a fluid replenishment port (not shown) is provided on the box body 400, and the fluid replenishment port is connected to the driven chamber 210, and the supply source injects fluid into the driven chamber 210 through the fluid replenishment port. Specifically, the fluid replenishment port is spaced apart from the drain port 430. In other embodiments, the fluid can also be replenished into the driven chamber 210 through the drain port 430.

[0056] exist Figure 1 In the illustrated embodiment, the driven assembly 200 further includes a second flexible bag 230, which is accommodated in the space enclosed by the driven plate 220 and the box body 400. At this time, the inner cavity of the second flexible bag 230 is the driven cavity 210, and the opening of the second flexible bag 230 is correspondingly connected to the drain port 430. Further, there is a gap between the driven plate 220 and the box body 400 to prevent the driven plate 220 from colliding with the inner wall of the box body 400 when moving in the box body 400 to generate friction, thereby ensuring that the driven plate 220 moves smoothly in the box body 400. In other embodiments, the second flexible bag 230 can also be replaced by a second flexible sleeve with openings at both ends, one end of the second flexible sleeve is sealed to the periphery of the driven plate 220, and the other end is sealed to the inner wall of the box body 400. In this way, the driven plate 220, the second flexible sleeve and the box body 400 cooperate to enclose the driven cavity 210 with a variable space size. The second flexible sleeve may be a soft rubber sleeve or a deformable bellows. In other embodiments, the periphery of the driven plate 220 may be in flexible contact with the inner wall of the box body 400, so that the driven plate 220 moves relative to the box body 400 and cooperates with the box body 400 to enclose a driven cavity 210 with a variable space size.

[0057] exist Figure 1 In the illustrated embodiment, the average cross-sectional area of ​​the cross section of the driven cavity 210 is equal to the average cross-sectional area of ​​the cross section of the driving cavity 110 .

[0058] It can be understood that the "cross section of the driving cavity 110" refers to the cross section obtained by cutting the driving cavity 110 with a plane perpendicular to the first preset direction K1. Since there are many planes perpendicular to the first preset direction K1, many cross sections will be obtained after cutting the driving cavity 110 with these planes. The areas of all cross sections are summed up and then the average value is obtained, which is the average cross-sectional area. When the driving cavity 110 is a regular columnar shape, the areas of all cross sections are equal. At this time, the end surface area of ​​the driving cavity 110 is equal to the average cross-sectional area.

[0059] It can be understood that, similarly, the "cross section of the driven cavity 210" refers to the cross section obtained by cutting the driven cavity 210 with a plane perpendicular to the second preset direction K2. Since there are many planes perpendicular to the second preset direction K2, many cross sections will be obtained after cutting the driven cavity 210 with these planes. The areas of all cross sections are summed up and then the average value is obtained, which is the average cross-sectional area. When the driven cavity 210 is a regular column, the areas of all cross sections are equal. At this time, the end surface area of ​​the driven cavity 210 is equal to the average cross-sectional area.

[0060] Combination Figure 1 and Figure 2 As shown, the average cross-sectional area of ​​the cross section of the driving cavity 110 is set to S1, the average cross-sectional area of ​​the cross section of the driven cavity 210 is set to S2, the spatial variation of the driving cavity 110 is V1, the spatial variation of the driven cavity 210 is V2, and the driving cavity 110 is Figure 1 The state shown expands along the first preset direction K1 to Figure 2 In the state shown, the travel of the driving chamber 110 is H1, and the driven chamber 210 is Figure 1 The displayed state shrinks to Figure 2 In the state shown, the contraction stroke of the driven chamber 210 along the second preset direction K2 is H2, and the following relationship exists: V1 = S1*H1, V2 = S2*H2.

[0061] 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 spatial variation V2 of the driven chamber 210 is only positively correlated with the stroke H2 of the driven chamber 210 contracting along the second preset direction K2, and the spatial variation V1 of the driving chamber 110 is only positively correlated with the stroke H1 of the driving chamber 110 expanding along the first preset direction K1. Thus, "the stroke H2 of the driven chamber 210 contracting along the second preset direction K2 is greater than the stroke H1 of the driving chamber 110 expanding along the first preset direction K1" will inevitably make "the spatial variation V2 of the driven chamber 210 greater than the spatial variation V1 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 replenished by the driving chamber 110, thereby realizing the first-level amplification of the flow rate of the discharged fluid.

[0062] In some other embodiments, when the contraction stroke H2 of the driven chamber 210 along the second preset direction K2 is greater than the expansion stroke H1 of the driving chamber 110 along the first preset direction K1, if the average cross-sectional area S2 of the cross section of the driven chamber 210 is further made greater than the average cross-sectional area S1 of the cross section of the driving chamber 110, the degree to which the "spatial variation V2 of the driven chamber 210" is greater than the "spatial variation V1 of the driving chamber 110" will be further amplified, thereby further increasing the flow rate of the fluid discharged from the driven chamber 210, thereby achieving a secondary amplification of the flow rate of the discharged fluid.

[0063] In some other embodiments, when the stroke H2 of the driven chamber 210 contracting along the second preset direction K2 is greater than the stroke H1 of the driving chamber 110 expanding along the first preset direction K1, the "spatial variation V2 of the driven chamber 210 is greater than the spatial variation V1 of the driving chamber 110", so as to achieve the first-order amplification of the flow rate of the discharged fluid. On this basis, if there are multiple driven chambers 210, the multiple driven chambers 210 can be contracted synchronously along the second preset direction K2. It can be understood that the transmission assembly 300 can act on multiple driven chambers 210 at the same time, so that the multiple driven chambers 210 contract synchronously. Therefore, on the basis that the spatial variation V2 of a single driven chamber 210 is greater than the spatial variation V1 of the driving chamber 110, the degree to which the "sum of the spatial variation V2 of multiple driven chambers 210" is greater than the "spatial variation V1 of the driving chamber 110" is further amplified, thereby further increasing the flow rate of the discharged fluid, and achieving the second-order amplification of the flow rate of the discharged fluid.

[0064] It should be noted that the arrangement of the multiple driven chambers 210 is not specifically set, and can be arranged linearly, circumferentially, or in an array. In addition, in other embodiments, when the stroke H2 of the driven chamber 210 contracting along the second preset direction K2 is greater than the stroke H1 of the driving chamber 110 expanding along the first preset direction K1, the average cross-sectional area S2 of the cross section of the driven chamber 210 can be further made greater than the average cross-sectional area S1 of the cross section of the driving chamber 110, and the driven chamber 210 can be set to be multiple, so as to achieve a three-stage amplification of the flow rate of the discharged fluid.

[0065] In some embodiments, a washing waterway is formed inside the body, and the fluid discharged from the discharge port of the driven cavity can enter the washing waterway, so as to flow downward from the upper side of the liquid reservoir to the liquid pool, thereby realizing a uniform flushing of the inner wall of the liquid reservoir from top to bottom. In addition, a jet waterway is formed inside the body, and the fluid discharged from the discharge port of the driven cavity can enter the jet waterway, and under the guidance of the jet waterway, enter the liquid pool and pass through the sewage outlet to carry the dirt out. In addition, a siphon is connected to the sewage outlet, and the siphon can suck the dirt and fluid in the liquid reservoir, so as to facilitate the smooth discharge of the dirt in the liquid reservoir.

[0066] In some embodiments, the bathroom equipment includes a control module, which is used to regulate and control the water injection or drainage in the driving cavity and the driven cavity.

[0067] The control module includes a first control valve, a control switch, a second control valve, a liquid level detection member and a contraction detection member. The control switch is connected to the first control valve to adjust the passage structure inside the first control valve according to a signal or operation. The second control valve is connected between the driven chamber and the fluid supply source. The liquid level detection member is arranged in the driven chamber to detect the liquid level height in the driven chamber, and the second control valve switches the flow channel between the driven chamber and the fluid supply source according to the feedback of the liquid level detection member. The contraction detection member is used to detect the compression degree of the driven chamber, and the control switch is connected to the contraction detection member and responds according to the feedback of the contraction detection member.

[0068] Specifically, the first control valve is connected between the drive chamber and the fluid supply source, and is also connected between the drive chamber and the driven chamber. It can be understood that the first control valve has three ports, the first port is connected to the fluid supply source, the second port is connected to the drive chamber, and the third port is connected to the driven chamber.

[0069] Before the flushing operation begins, the driving chamber is in a contracted state. The liquid level in the driven chamber is at a predetermined height. According to the liquid level detection result of the liquid level detection member, the passage between the driven chamber and the fluid supply source is blocked in the second control valve to prevent the fluid from being replenished into the driven chamber. At this time, the first port and the second port in the first control valve are blocked to prevent the fluid supply source from injecting fluid into the driving chamber.

[0070] 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 connected inside the first control valve, and the second port and the third port are cut off inside the first control valve, that is, the fluid supply source is connected to the driving chamber, and the driving chamber is isolated from the driven chamber. The fluid output from the fluid supply source is injected into the driving chamber through the first control valve, and the driving chamber gradually expands. Through the transmission of the transmission component, the fluid in the driven chamber flows out to the washing waterway and the injection waterway after passing through the discharge port, so as to wash the inner wall surface of the body and flush away the dirt at the sewage outlet.

[0071] During the drainage process of the driven chamber, as the fluid output from the fluid supply source is injected into the driving chamber, the driven chamber gradually contracts until it contracts to the maximum extent, and the drainage process of the compressed driven chamber ends. At this time, the contraction detection member is triggered, and the contraction detection member triggers the control switch to reset. The resetting of the control switch can cut off the first port and the second port inside the first control valve, thereby blocking the fluid supply source from injecting fluid into the driving chamber, and making the first port communicate with the third port, that is, making the driving chamber communicate with the driven chamber.

[0072] After the drainage of the driven chamber is completed, the remaining part of the fluid in the driven chamber forms a thrust on the inner wall of the driven chamber under the action of its own gravity, causing the driven chamber to expand. The expansion of the driven chamber will cause the liquid level in the driven chamber to drop. When the liquid level in the driven chamber drops to below the predetermined height value, the liquid level detection member triggers the second control valve, so that the passage between the driven chamber and the fluid supply source in the second control valve is opened, and the fluid supply source continues to inject fluid into the driven chamber. Under the action of the fluid injected by the fluid supply source, the driven chamber further expands and forces the driving chamber to contract through the transmission assembly to discharge the fluid. At this time, since 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 chamber, and the first port and the third port are connected, so that the fluid discharged from the driving chamber enters the driven chamber, so that the driving chamber can also serve as a supply source during the fluid replenishment operation of the driven chamber. When the liquid level of the driven chamber reaches the predetermined height, the fluid replenishment operation of the driven chamber is completed, and the driving chamber is also in a fully contracted state before the flushing operation begins.

[0073] It should be pointed out that the liquid level detection component is a float, which can float up with the increase of the liquid level in the driven chamber and fall with the decrease of the liquid level, and it can float and rise in a specific direction, so that when it rises and floats up, the valve port of the second control valve is accurately matched and blocked to block the communication between the driven chamber and the fluid supply source and the driving chamber, and when the liquid level drops, the liquid level detection component can drop to open the valve port of the second control valve to achieve the communication between the driven chamber and the fluid supply source and the driving chamber. In other embodiments, the liquid level detection component can also be any one or more components that can assist in detecting or determining the liquid level height, such as a mechanical float, a Hall sensor, an optical sensor, a water pressure sensor, a current sensor, etc.

[0074] Specifically, the contraction detection member is a trigger member arranged in the driven chamber, and the inner wall of the driven chamber contracts and deforms, and can abut against the contraction detection member when contracted to the maximum extent, so that the contraction detection member further acts on the control switch, and the control switch acts on the valve core of the first control valve mechanically or electrically, so that the valve core switches and connects the three ports on the valve body of the first control valve. In addition, the control switch can also be operated or reset by manually operating a button or handle on the control switch.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
