Description

Technical Field

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

[0002] As a bathroom equipment, the development trend of smart toilets is the same as that of mobile phones, with the cover becoming thinner and thinner, almost flat, to improve the appearance and save indoor space. The ceramic water tank of a traditional toilet needs to meet the height requirements to have enough potential energy and water volume to flush the toilet, but the height of the ceramic water tank often leads to a large indoor space being occupied, making this method gradually eliminated.

[0003] The ceramic-free water tank toilets on the market usually use tap water pressure to flush directly, which requires high water pressure. However, due to the unstable water pressure in old communities, when the water pressure is insufficient, the water output flow rate is slow, and it is impossible to ensure that the washing and flushing are clean.

[0004] Other non-ceramic water tank toilets ensure water volume by providing a booster pump, but this method causes the toilet structure to be complex, expensive and easy to break. Summary of the invention

[0005] Based on this, it is necessary to provide a flushing mechanism, drainage device and bathroom equipment that use a mechanical structure to increase the water flow rate, in order to address the problem that the water pressure of existing bathroom equipment cannot guarantee the flow rate due to water source limitations, and adding a booster pump leads to a complex structure.

[0006] A flushing mechanism, comprising:

[0007] A driving assembly having a driving cavity with a variable size for accommodating a fluid;

[0008] A driven component has a driven chamber with a variable space size for accommodating a fluid, wherein the number of the driven chambers is greater than the number of the driving chambers; and

[0009] A transmission component is arranged between the driving component and the driven component, wherein when the driving cavity expands due to the driving external force, the transmission component transmits the driving external force to compress the driven cavity and reduce the size to discharge the fluid, and the expansion space change of the driving cavity is less than the sum of the compression space change of the driven cavity.

[0010] Since the sum of the spatial changes of all the driven chambers is greater than the sum of the spatial changes of the driving chamber when the driving chamber expands, the amount of fluid discharged from each driven chamber at the same time is greater than the amount of fluid entering the driving chamber. The driving external force borne by the driven chamber is used to ensure the flushing flow rate, so there is no need to place the flushing mechanism at a certain height, which is conducive to optimizing the appearance design or internal structure layout of the bathroom equipment. The flushing mechanism makes full use of the water volume amplification form to allow a larger volume of fluid to clean the body of the bathroom equipment per unit time. Under the same volume, a larger flow rate has a better flushing effect on the body. Thereby solving the problem that the body of the bathroom equipment is not flushed cleanly under low water pressure, or using less water to meet the flushing effect, which is in line with the current concept of energy saving and environmental protection. At the same time, since there is no need to add an additional booster pump, the structure of the flushing mechanism is complicated, the cost is increased, or the stability is reduced.

[0011] In one embodiment, the driving assembly is provided with a main side port connected to the driving cavity, and the fluid is injected into the driving cavity from the main side port under the action of the driving external force.

[0012] In one embodiment, the driven assembly is provided with secondary side ports, and the number of the secondary side ports corresponds to the number of the driven chambers, so that when the driven chambers are compressed, the fluid in each driven chamber is discharged from the corresponding secondary side ports.

[0013] In one embodiment, each of the driven cavities is distributed one by one along a preset line; the preset line is a straight line, an arc, a circular line, or a spiral line.

[0014] In one embodiment, the driving cavity and each of the driven cavities are distributed one by one along a preset line; the preset line is a straight line, an arc, a circumferential line, or a spiral line.

[0015] In one of the embodiments, along the extension direction of the preset line, the transmission assembly is located between the driven cavity and the driving cavity.

[0016] In one embodiment, when the driving cavity expands due to the driving external force, the expansion space change of a single driving cavity is smaller than the compression space change of a single driven cavity.

[0017] In one embodiment, the transmission assembly includes a transmission member; when the driving cavity is expanded due to the driving external force, the transmission member squeezes the driven cavity along the expansion direction of the driving cavity, so that the compression of the driven cavity becomes smaller.

[0018] A drainage device comprises: a flushing mechanism and a regulating component connected to the flushing mechanism; the regulating component is used to control the on-off connection between the driving chamber and the fluid supply source, and the fluid input into the driving chamber generates a driving external force on the driving chamber to expand the driving chamber; the regulating component is also used to adjust the fluid replenishment of the driven chamber; after completing or interrupting the compression of the driven chamber, the regulating component is also used to guide the fluid in the driving chamber to replenish the driven chamber.

[0019] A bathroom device comprises: a drainage device and a body connected to the drainage device; the body is provided with a liquid pool, and a sewage outlet is provided at the bottom of the liquid pool, and the fluid discharged from the dynamic cavity is output to the liquid pool and / or the sewage outlet of the body to flush the inner wall of the liquid pool and / or discharge the dirt from the sewage outlet.

[0036] See also Figures 1 to 7 , is a bathroom device 100 according to an embodiment of the present invention, comprising a drainage device 20 and a body 30 connected to the drainage device 20, the body 30 is provided with a liquid pool 31, and a sewage outlet 311 is provided at the bottom of the liquid pool 31. In one embodiment, the bathroom device 100 is a toilet, and it can be understood that the bathroom device 100 can also be other equipment that needs to be flushed and cleaned, such as a wash basin, a bathtub, etc. Figure 6 and Figure 7 As shown in the figure, the drainage device 20 includes a flushing mechanism 40 and a regulating component 50 connected to the flushing mechanism 40. The body 30 may have a washing waterway 32 to guide the fluid to the upper side of the liquid pool 31 so that the fluid can evenly flush the inner wall of the liquid pool 31 from top to bottom. The body 30 may also have a jetting waterway 33 and a siphon 34 connected to the sewage outlet 311. The jetting waterway 33 guides the fluid in the drainage device 20 to the liquid pool 31 and discharges the dirt in the liquid pool 31 through the sewage outlet 311 and the siphon 34.

[0037] See also Figures 1 to 4 The present invention provides a flushing mechanism 40, comprising: a driving component 41, a driven component 42 and a transmission component 43. The driving component 41 has a driving chamber 411 for accommodating fluid and having a variable space size. The driven component 42 has a driven chamber 421 for accommodating fluid and having a variable space size, and the number of driven chambers 421 is multiple. The number of driven chambers 421 is greater than the number of driving chambers 411. The transmission component 43 is arranged between the driving component 41 and the driven component 42. When the driving chamber 411 is expanded due to a driving external force, the transmission component 43 can be driven, and the driving external force is transmitted by the transmission component 43, so that the driven chamber 421 is compressed and reduced, and the fluid stored in the driven chamber 421 is discharged. When the driving chamber 411 is expanded by a driving external force, the change in its expansion space is less than the sum of the change in the compression space of the driven chamber 421.

[0038] By injecting fluid into each driven cavity 421 in advance, the internal space of each driven cavity 421 is fully expanded, and the driving cavity 411 is emptied in advance, so that the driving cavity 411 is in a contracted state. When the fluid supply source 700 that generates the driving external force injects fluid into the contracted driving cavity 411, the driving cavity 411 generates spatial expansion due to the filling of the fluid; when the driving cavity 411 expands, the driving external force is transmitted to the transmission component 43, and the driven cavity 421 is compressed through the transmission effect of the transmission component 43, so that the stored fluid in each driven cavity 421 is discharged to the body 30 of the bathroom equipment 100 at the same time. Since when the driving cavity 411 expands, the sum of the spatial changes of all the driven cavities 421 is greater than the spatial change of a single driving cavity 411, or the sum of the spatial changes of all the driven cavities 421 is greater than the sum of the spatial changes of multiple driving cavities 411, the amount of fluid discharged from each driven cavity 421 at the same time is greater than the amount of fluid entering the driving cavity 411. During the drainage process, the flushing flow rate can be ensured by utilizing the driving external force borne by the driven cavity 421, so there is no need to place the flushing mechanism 40 at a certain height, which is conducive to optimizing the appearance design or internal structure layout of the bathroom equipment 100.

[0039] See also Figure 6 and Figure 7 The fluid discharged into the body 30 of the bathroom equipment 100 can evenly flush the inner wall of the body 30 through the washing water channel 32, or enter the siphon 34 through the jetting water channel 33 to suck out the dirt at the bottom of the liquid pool 31.

[0040] In some embodiments, the inner wall of the driving cavity 411 is at least partially flexible.

[0041] See also Figure 1 and Figure 3In one embodiment, the driving assembly 41 includes a main side housing 412, an active plate 414 and a main side flexible member 415. The active plate 414 is movably accommodated in the main side housing 412, and the main side flexible member 415 is connected between the main side housing 412 and the active plate 414. Along the expansion direction of the driving cavity 411, the active plate 414 and the main side housing 412 are sealed and connected to different parts of the main side flexible member 415 to cooperate to form the driving cavity 411. The active plate 414 is connected to the transmission assembly 43, and during the movement of the active plate 414, the transmission assembly 43 moves synchronously. The main side housing 412 is provided with a main side port 413 connected to the driving cavity 411, and the fluid flows into or out of the driving cavity 411 through the main side port 413. The main side flexible member 415 is cylindrical, one end of which is connected to the active plate 414 or fixedly embedded in the active plate 414, and the other end is connected to the main side housing 412 or fixedly embedded in the main side housing 412. In one embodiment, a gap is provided between the edge of the active board 414 and the inner wall of the main side housing 412 to facilitate the active board 414 to move in the main side housing 412. Furthermore, the main side flexible member 415 is tapered and has a large end and a small end, the small end is connected to the active board 414, and the large end is connected to the main side housing 412.

[0042] In one embodiment, the inner wall of the driven cavity 421 is at least partially flexible.

[0043] See also Figure 1 and Figure 2 In one embodiment, the driven component 42 includes a secondary side flexible bag 422, and the inner cavity of the secondary side flexible bag 422 is used as a driven cavity 421; when the driving cavity 411 is expanded due to the driven external force, the driving transmission component 43 is driven to compress the secondary side flexible bag 422 to reduce the size and discharge the fluid in the driven cavity 421.

[0044] See also Figure 1 and Figure 2 In one embodiment, the transmission assembly 43 includes a support plate 431, a secondary push plate 432 and a transmission member 433. The secondary flexible bag 422 is arranged between the support plate 431 and the secondary push plate 432. The transmission member 433 connects the secondary push plate 432 and the drive assembly 41, more specifically, connects the active plate 414 in the drive assembly 41. When the drive cavity 411 is expanded due to the driving external force, the drive cavity 411 acts on the secondary push plate 432 through the transmission member 433, so that the secondary push plate 432 moves close to the support plate 431 to compress the secondary flexible bag 422. The number of support plates 431 and secondary push plates 432 may be the same as or different from the number of secondary flexible bags 422. For example, in one embodiment, a secondary flexible bag 422 is arranged between a corresponding support plate 431 and the secondary push plate 432, or a plurality of secondary flexible bags 422 may be arranged. All secondary push plates 432 are connected to the transmission member 433. In Figure 1In the embodiment shown in the figure, the secondary side push plate 432 is connected to the transmission member 433 in an indirect connection, that is, each secondary side push plate 432 is connected in sequence, and then directly connected to the transmission member 433 through a secondary side push plate 432 closest to the transmission member 433. In other embodiments, the secondary side push plate 432 and the transmission member 433 may be connected in a direct connection, for example, a transmission rod directly connected is provided between each secondary side push plate 432 and the transmission member 433. In some embodiments, each support plate 431 is fixedly connected to each other. Further, each support plate 431 is connected to each other and is also fixedly connected to the main side housing 412.

[0045] exist Figure 1 and Figure 2 In the illustrated embodiment, each secondary side flexible bag 422 has the same shape and size. In some embodiments not shown in the figure, each secondary side flexible bag 422 may have a different shape. In some embodiments not shown in the figure, each secondary side flexible bag 422 may have a different size.

[0046] Further, the transmission assembly 43 also includes a secondary side limit plate 434, which extends in a direction parallel to the moving track of the secondary side push plate 432; projected on a plane perpendicular to the moving track of the secondary side push plate 432, the secondary side limit plate 434 extends or is distributed around the secondary side flexible bag 422 to limit the deformation space of the secondary side flexible bag 422. The secondary side limit plate 434 can be used as an intermediate connecting piece connecting each secondary side push plate 432, and during the movement of the secondary side push plate 432, the secondary side limit plate 434 moves with the secondary side push plate 432. The secondary side limit plate 434 can also be fixedly connected to the support plate 431, and during the movement of the secondary side push plate 432, the secondary side push plate 432 moves relative to the secondary side limit plate 434 and the support plate 431, and compresses and deforms the secondary side flexible bag 422 in the space defined by the secondary side limit plate 434 and the support plate 431.

[0047] See also Figure 1 and Figure 4 In one embodiment, each driven cavity 421 is distributed along a preset line 423; the preset line 423 is a straight line, an arc, a circumference, or a spiral line; in another embodiment, the driving cavity 411 and each driven cavity 421 are distributed along a preset line 423; the preset line 423 is a straight line, an arc, a circumference, or a spiral line. In some embodiments, the driving cavity 411 can be one or more, but the number of driving cavities 411 is less than the number of driven cavities 421. At the same time, the sum of the expansion space changes of the driving cavity 411 is less than the sum of the compression space changes of the driven cavity 421.

[0048] See also Figure 5A and Figure 5B, the regulating component 50 is used to control the connection between the driving chamber 411 and the fluid supply source 700. The fluid input into the driving chamber 411 generates a driving external force on the driving chamber 411, so that the driving chamber 411 expands; the regulating component 50 is also used to adjust the fluid replenishment of the driven chamber 421; after the compression of the driven chamber 421 is completed, the regulating component 50 is also used to guide the fluid in the driving chamber 411 to replenish the driven chamber 421, and is also used to control the connection between the driven chamber 421 and the fluid supply source 700, replenishing the fluid provided by the fluid supply source 700 to the driven chamber 421. In some embodiments, the fluid supply source 700 is the output of the municipal tap water pipeline, and the fluid injected into the driving chamber 411 or the driven chamber 421 is tap water. In some other embodiments, the fluid supply source 700 can also be the output of the municipal tap water pipeline after the booster pump, or it can be the pumping output of the external pump body of the bathroom equipment 100 to the external water storage.

[0049] In some embodiments, the regulating component 50 includes a main-side switching valve 51 and a switch control 52; the main-side switching valve 51 is connected between the fluid supply source 700 and the drive chamber 411. When the switch control 52 is triggered, the fluid supply source 700 is connected to the drive chamber 411 through the main-side switching valve 51, and the main-side switching valve 51 cuts off the flow channel between the drive chamber 411 and the slave chamber 421. If there is a flow channel between the drive chamber 411 and other fluid storage containers, the flow channel between the drive chamber 411 and other fluid storage containers is also cut off. The drainage device 20 also includes a drainage pipe 60 connected to the slave chamber 421, and the drainage pipe 60 leads to the liquid pool 31 to guide the fluid discharged from the slave chamber 421 to flow to the liquid pool 31. Specifically, the horizontal height of the drainage pipe 60 is at least partially higher than the horizontal height of the slave chamber 421, and the local part is the high-level section 62 of the drainage pipe 60. Furthermore, each driven chamber 421 is transitionally connected to the drain pipe 60 through a junction 424, and the level of the junction 424 is higher than the main body of the driven chamber 421 and slightly lower than the high section 62 of the drain pipe 60. Figure 5A and Figure 5B In the illustrated embodiment, the driven chambers 421 are connected from their top sides to the junction 424 .

[0050] Before the liquid level in the driven chamber 421 and the drain pipe 60 rises to a level higher than the high-level section 62 of the drain pipe 60, the fluid is confined in the driven chamber 421 or the junction 424 to prevent the fluid in the driven chamber 421 from spontaneously flowing out around the drain pipe 60 due to its own gravity. When the driven chamber 421 is compressed, the liquid level in the driven chamber 421 and the drain pipe 60 rises and passes over the high-level section 62 of the drain pipe 60, thereby flowing out into the body 30. In some embodiments not shown in the figure, the drain pipe 60 and the junction 424 may be arranged to be lower than the driven chamber 421, and the driven chamber 421 is connected to the junction 424 from its bottom side. By arranging valves such as pressure valves or solenoid valves in the drain pipe 60 and the junction 424, the fluid in the driven chamber 421 is prevented from spontaneously being injected into the drain pipe 60 and discharged due to its own gravity. When the driving chamber 411 expands and compresses the driven chamber 421 , the pressure in the driven chamber 421 increases and the pressure valve element opens, so that the fluid in the driven chamber 421 enters the drain pipe 60 and is discharged to the body 30 .

[0051] See also Figure 5A and Figure 5B In another embodiment, the switch control component 52 is a valve structure or a manual valve. When the switch control component 52 is opened, the tap water of the municipal tap water pipeline passes through the switch control component 52 and acts on the main side switching valve component 51, so that the main side switching valve component 51 of the three-way structure is switched to a state in which the municipal tap water pipeline is connected to the driving chamber 411 and the driving chamber 411 is isolated from the driven chamber 421. The injection of tap water causes the active plate 414 to move away from the main side shell 412 and the driving chamber 411 tends to expand. The active plate 414 acts on the secondary side push plate 432 through the transmission component 433, and pushes the secondary side push plate 432 toward the support plate 431, respectively squeezing the multiple secondary side flexible bags 422, so that the water stored in the driven chamber 421 is discharged to the body 30 of the bathroom equipment 100, so as to output a larger volume of water to the body 30.

[0052] Please read again Figure 5A and Figure 5B In order to facilitate the automatic control of the replenishment of water in the driven chamber 421, the regulating component 50 also includes a water tank 53, and the water tank 53 is connected with a liquid level control component 531, a liquid inlet valve 532, a liquid replenishing pipe 533 and a one-way valve 534. The liquid inlet valve 532 is arranged between the water tank 53 and the fluid supply source 700. The liquid level control component 531 adjusts the on-off of the liquid inlet valve 532 to maintain the fluid in the water tank 53 at a predetermined liquid level 535; the inner cavity of the water tank 53 is connected to the driven chamber 421 through the liquid replenishing pipe 533, and the one-way valve 534 is arranged on the liquid replenishing pipe 533 to prevent the fluid in the driven chamber 421 from flowing back to the water tank 53; the placement height of the driven chamber 421 is lower than the predetermined liquid level 535.

[0053] exist Figure 5AIn the illustrated embodiment, when the drainage device 20 receives a drainage instruction, the switch control component 52 is opened, and the tap water of the municipal tap water pipeline passes through the switch control component 52 and applies water pressure to the main side switching valve component 51, so that the main side switching valve component 51 of the three-way structure is switched to a state in which the municipal tap water pipeline is connected to the driving chamber 411 and the driving chamber 411 is isolated from the water tank 53. The injection of tap water causes the active plate 414 to move away from the main side shell 412 and the driving chamber 411 tends to expand. The active plate 414 acts on the secondary side push plate 432 through the transmission component 433, and pushes the secondary side push plate 432 toward the support plate 431, respectively squeezing the multiple secondary side flexible bags 422, so that the water stored in the driven chamber 421 is discharged from the drainage pipe 60, so as to output a larger volume of water to the main body 30. In some embodiments, the switch control element 52 is connected between the main-side switching valve element 51 and the fluid supply source 700; the switch control element 52 is an electromagnetic control valve. When the switch control element 52 is controlled to be turned on, the pressure of the fluid causes the main-side switching valve element 51 to switch to open the flow channel between the driving chamber 411 and the fluid supply source 700 and to cut off the flow channel between the driving chamber 411 and the water tank 53; after the water stored in the slave chamber 421 is fully discharged, the switch control element 52 is controlled to be cut off, and the driving chamber 411 loses the driving external force provided by the fluid and completes the compression of the slave chamber 421. Before the water stored in the slave chamber 421 is fully discharged, if the switch control element 52 is controlled to be cut off or the fluid supply source 700 stops outputting, the driving chamber 411 loses the driving external force provided by the fluid and stops expanding, and the compression of the slave chamber 421 is interrupted. Specifically, the fluid supply source 700 may stop outputting because the municipal tap water pipeline is cut off or the valve of the fluid supply source 700 stops the fluid output of the fluid supply source 700.

[0054] See also Figure 5A After the compression of the driven chamber 421 is completed or interrupted, the gravity of the accumulated water in the secondary flexible bag 422 generates pressure on the inner wall of the secondary flexible bag 422. When the secondary flexible bag 422 expands and deforms under the pressure, the liquid level in the secondary flexible bag 422 or the drain pipe 60 drops. Since the placement height of the driven chamber 421 is lower than the predetermined liquid level 535 and the water tank 53 is connected to the secondary flexible bag 422 through the liquid replenishing tube 533, when the liquid level in the secondary flexible bag 422 or the drain pipe 60 is lower than the predetermined liquid level 535, under the principle of the communicating vessel, the tap water in the water tank 53 is spontaneously replenished to the secondary flexible bag 422 through the liquid replenishing tube 533 until the liquid level in the secondary flexible bag 422 or the drain pipe 60 reaches the predetermined liquid level 535.

[0055] The liquid level control component 531 can provide feedback through various forms of liquid inlet valves 532 to keep the liquid level in the water tank 53 at a predetermined liquid level 535.

[0056] exist Figure 5A and Figure 5BIn the illustrated embodiment, a liquid inlet valve 532 is connected between the fluid supply source 700 and the water tank 53; a liquid level control member 531 floats in the water tank 53, and switches the liquid inlet valve 532 on and off according to the floating height. When the liquid level control member 531 floats to a level higher than or equal to a predetermined liquid level 535, the liquid level control member 531 drives the liquid inlet valve 532 to enter a closed state through a lever transmission, thereby preventing tap water from entering the water tank 53. When the liquid level control member 531 floats to a level lower than the predetermined liquid level 535, the liquid level control member 531 drives the liquid inlet valve 532 to enter an open state through a lever transmission, thereby allowing tap water to be replenished and enter the water tank 53, until the liquid level control member 531 floats to a level higher than or equal to the predetermined liquid level 535, thereby turning the liquid inlet valve 532 off again.

[0057] In some embodiments not shown in the figure, the floating change of the liquid level control member 531 can also adjust the on and off of the liquid inlet valve 532 through the transmission of pressure-sensitive sensors, Hall effect or other sensing methods. Specifically, the liquid level control member 531 floats on the liquid level in the water tank 53. When the liquid level in the water tank 53 is lower than the predetermined liquid level 535, the liquid level control member 531 floats down and opens the liquid inlet valve 532 through photoelectric sensing, pressure-sensitive sensing or other transmission sensing methods, and the circulation supply source 700 replenishes the fluid into the water tank 53 through the liquid inlet valve 532; when the liquid level in the water tank 53 is higher than the predetermined liquid level 535, the liquid level control member 531 closes the liquid inlet valve 532 through photoelectric sensing, pressure-sensitive sensing or other matching methods, and stops the fluid from being replenished into the water tank 53.

[0058] In other embodiments, the liquid level control component 531 is not limited to being a floating component, and any other coordination method that can enable the fluid in the water tank 53 to maintain a predetermined liquid level 535 can be adopted between the liquid level control component 531 and the liquid inlet valve 532 .

[0059] See also Figure 5A Since the main-side switching valve component 51 is connected between the driving chamber 411 and the water tank 53, when the drainage instruction lasts for a certain period of time and is revoked, the switch control component 52 connected between the main-side switching valve component 51 and the fluid supply source 700 is controlled to be cut off, and the main-side switching valve component 51 loses the pressure of the fluid, so that the main-side switching valve component 51 with a three-way structure is switched to a state in which the driving chamber 411 is connected to the water tank 53 and the fluid supply source 700 is isolated from the driving chamber 411, so as to guide the accumulated water in the driving chamber 411 to be replenished to the water tank 53.

[0060] The fluid in the water tank 53 is automatically replenished into the driven chamber 421 due to the height difference, and the driven chamber 421 expands due to the replenished fluid. The driven chamber 421 compresses the driving chamber 411 through the transmission of the transmission assembly 43, and the fluid discharged from the driving chamber 411 flows to the water tank 53 through the main side switching valve 51. Figure 5A and Figure 5B, the secondary side flexible bag 422 expands due to the tap water from the water tank 53, and pushes the secondary side push plate 432, so that the secondary side push plate 432 moves away from the support plate 431. The secondary side push plate 432 reacts to the active plate 414 through the transmission member 433, so that the active plate 414 moves close to the main side housing 412, and the driving chamber 411 is compressed to discharge fluid to the water tank 53. Specifically, the accumulated water in the driving chamber 411 flows to the water tank 53 through the main side port 413 and the main side switching valve member 51 in sequence to replenish the water stored in the water tank 53. Since the tap water in the water tank 53 can replenish the driven chamber 421, the accumulated water in the driving chamber 411 can be indirectly replenished to the driven chamber 421.

[0061] See also Figure 5A , the local placement height of the drain pipe 60 is higher than the predetermined liquid level 535. In other words, the highest part of the drain pipe 60 is set at a higher position than the main structure of the water tank 53. Unlike the traditional water tank 53 that must be set at a higher position to generate potential energy to drain water to the drain pipe 60, the setting position of the water tank 53 can be more flexible and can reduce the overall volume of the drainage device 20, thereby improving the appearance layout. Further, in order to prevent the accumulated water discharged from the drain pipe 60 from continuously sucking tap water from the water tank 53, the liquid replenishment tube 533 and the secondary side flexible bag 422 into the drain pipe 60 under negative pressure, the drainage device 20 also includes a siphon elimination valve 61 connected to the drain pipe 60, and the siphon elimination valve 61 is connected to the local part of the drain pipe 60 that is higher than the predetermined liquid level 535. When the secondary side flexible bag 422 is compressed and discharges the stored water through the drain pipe 60, the siphon elimination valve 61 isolates the inner and outer air pressure environments of the drain pipe 60 under the high pressure of the stored water, thereby preventing the stored water from leaking from the siphon elimination valve 61. After the compression of the driven chamber 421 is completed or interrupted, the stored water being discharged from the drain pipe 60 forms a negative pressure inside the drain pipe 60 due to the loss of the force of the secondary flexible bag 422. Under the action of the negative pressure, the siphon elimination valve 61 connects the air pressure environment inside and outside the drain pipe 60, and the air flow outside the drain pipe 60 enters the inside of the drain pipe 60, eliminating the negative pressure in the drain pipe 60 and interrupting the water flow in the drain pipe 60. Restricted by the one-way valve 534, the fluid in the driven chamber 421 cannot flow back to the water tank 53 when draining.

[0062] In some other embodiments, the drainage command is removed after the driven chamber 421 is compressed to a certain extent, and the switch control component 52 is triggered to cut off the flow channel for the external fluid to be injected into the driving chamber 411, and the driving chamber 411 stops expanding to complete the compression process of the driven chamber 421; or, when the water replenishment command is received, the drainage command is removed, and the switch control component 52 cuts off the flow channel for the external fluid to be injected into the driving chamber 411 after the drainage command is removed.

[0063] In some embodiments, the water replenishment instruction is removed after continuing for a predetermined time, so that the flow channel for external fluid to be injected into the driven chamber 421 is cut off, the driven chamber 421 stops expanding, and the water replenishment process of the driven chamber 421 is completed; or, the water replenishment instruction is removed after the driven chamber 421 expands to a certain extent, so that the flow channel for external fluid to be injected into the driven chamber 421 is cut off, the driven chamber 421 stops expanding, and the water replenishment process of the driven chamber 421 is completed; or, when the drainage instruction is received, the water replenishment instruction is removed, and the removal of the water replenishment instruction cuts off the flow channel for external fluid to be injected into the driven chamber 421.

[0064] See also Figure 6 and Figure 7 , is a bathroom device 100 according to an embodiment of the present invention, wherein the drainage device 20 is accommodated in the body 30, so that the height of the drainage device 20 is lower than the upper edge of the liquid pool 31, thereby facilitating the control of the volume of the bathroom device 100. Figure 6 In the illustrated embodiment, the driven component 42 is disposed transversely in the body 30, and the main body of the water tank 53 is disposed at a position higher than the upper edge of the driven component 42 and lower than the upper edge of the liquid pool 31. The body 30 is provided with an inner cavity on one side of the liquid pool 31, and the driven component 42 is accommodated in the inner cavity. Furthermore, the inner cavity also accommodates the driving component 41. In some embodiments not shown in the figure, the driven component 42 can also be arranged in other directions in the body 30. The regulating component 50 can be connected to the body 30, or external to the body 30.

[0065] exist Figure 6 In the illustrated embodiment, a portion of the washing waterway 32 is distributed around the upper edge of the liquid pool 31. The body 30 has a liquid outlet 321 connected to the washing waterway 32. The output port of part of the secondary side flexible bag 422 in the driven component 42 is directly connected to the washing waterway 32. When the secondary side flexible bag 422 is compressed and discharges the stored water, the stored water flows along the washing waterway 32 around the edge of the liquid pool 31, and the water flow in the washing waterway 32 flows to the inner wall of the liquid pool 31 through the liquid outlet 321, so as to produce a flushing effect on the inner wall of the liquid pool 31 from different angles. In some embodiments not shown in the figure, the spray waterway 33 can also be supplied with water by other means, and the output ports of all the driven chambers 421 are connected to the washing waterway 32 through the drain pipe 60, so that the stored water of all the driven chambers 421 is concentrated and output to the inner wall of the flushing liquid pool 31.

[0066] exist Figure 6In the illustrated embodiment, the output ports of some secondary flexible bags 422 in the driven assembly 42 are connected to the jetting waterway 33 through the drain pipe 60. The connection between the jetting waterway 33 and the siphon 34 is located at the lower side of the drain port 311 of the liquid pool 31. When the water flows through the connection between the jetting waterway 33 and the siphon 34, the flow rate of the water flow forms a negative pressure at the lower side of the drain port 311, thereby sucking the dirt and accumulated water in the liquid pool 31 out of the liquid pool 31 from the drain port 311, and finally discharged out of the body 30 along with the siphon 34. In some embodiments not shown in the figure, the washing waterway 32 can also be supplied with water by other means, and the output ports of all driven chambers 421 are connected to the jetting waterway 33 through the drain pipe 60, so that the stored water of all driven chambers 421 is concentrated through the lower side of the drain port 311.

[0067] The flushing process of the bathroom device 100 includes the following steps:

[0068] S10: Setting a driving chamber 411 and a driven chamber 421 with variable space sizes for accommodating fluid, wherein the expansion space variation of the driving chamber 411 is smaller than the compression space variation of the driven chamber 421;

[0069] S20: If a drainage instruction is received, the external fluid is allowed to enter the driving chamber 411, the driving chamber 411 expands and generates a driving external force, so that the driven chamber 421 is compressed and the fluid contained in the driven chamber 421 is discharged, until the compression process of the driven chamber 421 is completed or interrupted;

[0070] S30: If a water replenishment instruction is received, external fluid is allowed to enter the driven chamber 421 to expand the driven chamber 421 and compress the driving chamber 411, and the fluid in the driving chamber 411 is transferred to the driven chamber 421 or the water tank 53 until the water replenishment process of the driven chamber 421 is completed or interrupted.

[0071] In this embodiment, when the external fluid is injected into the driving chamber 411, the flow channel for the driving chamber 411 to export the fluid to the driven chamber 421 is cut off. The drainage instruction is removed after a predetermined time, so that the flow channel for the external fluid to be injected into the driving chamber 411 is cut off, the driving chamber 411 stops expanding, and the compression process of the driven chamber 421 is completed; after the compression process of the driven chamber 421 is completed, a water replenishment instruction is generated, and the flow channel for the external fluid to be injected into the driven chamber 421 or the water tank 53 is opened. When the water replenishment instruction is received, the flow channel for the driving chamber 411 to export the fluid to the driven chamber 421 is opened. The water replenishment instruction is removed after the predetermined liquid level 535 is reached in the driven chamber 421, so that the flow channel for the external fluid to be injected into the driven chamber 421 is cut off, the driven chamber 421 stops expanding, and the water replenishment process of the driven chamber 421 is completed.
