Referring to fig. 1 and 2, fig. 1 is a schematic structural view of a toilet 10 in some embodiments when a movable element 12 is in a closed state, and fig. 2 is a schematic structural view of the toilet 10 in some embodiments when the movable element 12 is in an open state. In some embodiments, the toilet 10 includes a main body 11 and a movable member 12 rotatably connected to the main body 11, the main body 11 is provided with a bowl 110, and the movable member 12 has an open state and a closed state with respect to the bowl 110. Specifically, when the movable member 12 is in the closed state, the movable member 12 covers the urinal 110, and when the movable member 12 is in the open state, the movable member 12 rotates relative to the main body 11 to a position away from the urinal 110. For example, the movable member 12 may be a seat of the toilet 10, and when the movable member 12 is in the closed state, the movable member 12 is covered on the bowl 110 for the user to sit thereon. For another example, the movable element 12 may also be a cover of the toilet 10, and when the movable element 12 is in a closed state, the movable element 12 is covered on the urinal 110 to close the space in the urinal 110, so as to prevent the odor in the urinal 110 from leaking.

Referring to fig. 1-4 together, the toilet 10 further includes a transmission element 13 and a power module 18, the power module 18 includes a body 180 and a moving element 191, the body 180 is fixedly disposed on the main body 11, the moving element 191 is rotatably connected to the body 180, one end of the transmission element 13 is connected to the moving element 12, and the other end is connected to the moving element 191. It can be understood that, when the moving element 191 rotates relative to the body 180, the transmission element 13 can drive the moving element 12 to rotate relative to the main body 11, so that the moving element 12 is switched from the closed state to the open state.

Further, in some embodiments, the power module 18 further includes a shape-changing element 192, the shape-changing element 192 connects the body 180 and the moving element 191, and the body 180, the moving element 191 and the shape-changing element 192 together enclose the water inlet space 193. For example, the body 180 may be substantially a hollow structure with a single side opened, the moving member 191 is rotatably connected to the body 180 and corresponds to the opened position of the body 180, and the deformation member 192 is located between the body 180 and the moving member 191 and connects the body 180 and the moving member 191, thereby defining a part of the hollow space of the body 180 as the water inlet space 193.

It should be noted that in the present application, the tap water conduit 196 may be connected to a municipal water supply network, and the pressure of tap water flowing from the tap water conduit 196 into the inlet space 193 may be between 0.5 kg and 0.7 kg. When the tap water flows into the water inlet space 193 from the tap water pipe 196, the moving member 191 is pressed, so that the moving member 191 is pushed to rotate relative to the body 180 in a direction away from the body 180, and the deformation member 192 is deformed during the rotation of the moving member 191 relative to the body 180.

The toilet 10 drives the moving element 191 to rotate relative to the body 180 by the water pressure of the tap water, so as to drive the moving element 12 to rotate relative to the main body 11 through the transmission element 13 to open, thereby realizing the automatic opening operation of the moving element 12. Meanwhile, because the power for the moving element 191 to rotate relative to the body 180 comes from the pressure of water, the operation cost of the power module 18 is low compared with the mode that the motor or the motor drives the moving element 12 to open, and the design of energy conservation and environmental protection can be realized.

In some embodiments, the deformation element 192 may be made of an elastic material, such as rubber. The shape-changing element 192 has an initial state and an elastically stretched state, and when the shape-changing element 192 is in the elastically stretched state by an external force, the shape-changing element 192 tends to return to the initial state. In some embodiments, the shape-changing element 192 is in an initial state when the movable element 12 is in the closed state, and the shape-changing element 192 is in an elastically stretched state when the movable element 12 is pulled to be opened by rotating the movable element 191 relative to the body 180. In some embodiments, the shape-changing element 192 is at a maximum tension when the displacement element 191 is rotated relative to the body 180 to the point where the movable element 12 is just in the open position. Therefore, the deformation element 192 can limit the maximum rotation amount of the moving element 191 relative to the body 180, so as to prevent the moving element 191 from being separated from the body 180, and facilitate the movable element 12 to be switched to the open state.

In some embodiments, the transmission element 13 may be a rope. Of course, the transmission element 13 may be any suitable transmission structure such as a belt, a link, etc., as long as the moving element 191 can pull the movable element 12 open through the transmission element 13. In some embodiments, the movable element 12 is rotatably connected to the main body 11 via the rotating shaft 120, the moving element 191 is located on a side of the body 180 facing away from the movable element 12, one end of the transmission element 13 is wound on the rotating shaft 120, and the other end is fixedly connected to the moving element 191. Thus, when the moving element 191 rotates in a direction away from the movable element 12 relative to the body 180 under the pressure of tap water, the movable element 12 can be pulled by the transmission element 13 to rotate along the rotation shaft 120 to be opened relative to the main body 11.

In some embodiments, the transmission element 13 is slidably disposed through the body 180. From this, body 180 can play limiting displacement to drive element 13, is favorable to promoting the stability of transmission process, also can make drive element 13 be difficult to break away from power module 18 simultaneously.

As shown in fig. 5 and 6, in some embodiments, the shifting element 191 is provided with a through hole 1910 through which the shifting element 191 passes, and a binding hole 1911 is further provided on a side of the shifting element 191 facing away from the body 180. The power module 18 includes a binding element (not shown), the transmission element 13 sequentially penetrates through the body 180 and the through hole 1910, and an end of the transmission element 13 is located on a side of the moving element 191 facing away from the body 180. The binding member penetrates the end of the driving member 13 and the binding hole 1911 to fixedly connect the driving member 13 with the moving member 191. Specifically, the binding element may be a screw, and the binding hole 1911 may be a threaded hole. Of course, the driving element 13 may be fixedly connected to the moving element 191 by any other suitable connection manner, for example, in the embodiment shown in fig. 3 and 4, the driving element 13 is inserted through the through hole 1910 of the moving element 191, the end of the driving element 13 is located on the side of the moving element 191 away from the mounting seat 182, the size of the end of the driving element 13 is larger than the radial size of the through hole 1910, and the end of the driving element 13 is clamped to the side of the moving element 191 away from the body 180 to fixedly connect the driving element 13 and the moving element 191.

Referring to fig. 4 and 5, in some embodiments, the toilet 10 further includes a sleeve 14, a first partition 15 and a second partition 16, the first partition 15 and the second partition 16 are both fixedly disposed on the main body 11, and two ends of the sleeve 14 are respectively fixedly connected to the first partition 15 and the second partition 16. One end of the transmission element 13 penetrates through the first partition plate 15 and is wound on the rotating shaft 120, the other end of the transmission element 13 penetrates through the second partition plate 16 and is fixedly connected with the moving element 191, the part, located between the first partition plate 15 and the second partition plate 16, of the transmission element 13 is located in the sleeve 14, and the transmission element 13 is in sliding fit with the first partition plate 15, the second partition plate 16 and the sleeve 14. It is understood that if only the transmission element 13 is provided, the transmission element 13 needs to extend along a straight line in order to ensure that the moving element 191 can effectively drive the movable element 12 to open through the transmission element 13. And first baffle 15, second baffle 16, sleeve pipe 14 and transmission element 13 cooperation for transmission element 13 need not to extend along the straight line, can extend along arbitrary applicable curve, thereby makes the position setting of power module 18 can adapt to the more different structural design of closestool 10, promotes the space utilization of closestool 10.

For example, in some embodiments, the main body 11 has a mounting surface 111, and the movable element 12 is rotatably disposed on the mounting surface 111. The mounting surface 111 further has a receiving groove 112, and at least a portion of the power module 18 and the second partition 16 are received in the receiving groove 112. Therefore, through the cooperation of the first partition 15, the second partition 16, the sleeve 14 and the transmission element 13, the power module 18 and the rotating shaft 120 can be located on different horizontal lines in the vertical direction, so as to adapt to different structural designs of the toilet bowl 10, improve the space utilization rate of the toilet bowl 10, and facilitate the compression of the volume of the toilet bowl 10. The design of the power module 18 accommodated in the accommodating groove 112 is also beneficial to protecting the power module 18, so that the power module 18 is not easily damaged by scraping.

Referring to fig. 7, 8 and 9 together, in some embodiments, the body 180 includes a fixing seat 181 and a mounting seat 182, the fixing seat 181 is fixedly connected to the main body 11, the mounting seat 182 is disposed in the hollow space of the fixing seat 181 and is fixedly connected to a side of the fixing seat 181 facing the moving element 191, the deformation element 192 is respectively connected to the mounting seat 182 and the moving element 191, and the moving element 191 is rotatably connected to the mounting seat 182. Specifically, the mounting seat 182 may be detachably connected to the fixing seat 181 by any suitable connection manner, such as a snap, an engagement, a threaded connection, and the like. Therefore, when the fixing base 181 is fixedly disposed on the main body 11, the mounting base 182, the deformation element 192 and the moving element 191 are connected to each other to form a structural whole, so that the mounting base 182, the deformation element 192 and the moving element 191 are conveniently mounted on the fixing base 181 or dismounted from the fixing base 181, and therefore, the mounting and maintenance of the power module 18 are facilitated.

As shown in fig. 4 and 9, in some embodiments, the deformation element 192 is sleeved on the mounting seat 182 and the moving element 191 respectively. Further, in some embodiments, the outer circumferential surface of the moving element 191 is circumferentially provided with a first fixing groove 1912, the outer circumferential surface of the mounting seat 182 is circumferentially provided with a second fixing groove 183, the inner circumferential surface of the deformation element 192 is circumferentially provided with a first fixing portion 194 and a second fixing portion 195 that are spaced from each other in a protruding manner, and the first fixing portion 194 and the second fixing portion 195 are both substantially annular structures. The first fixing portion 194 is fitted into the first fixing groove 1912, and the second fixing portion 195 is fitted into the second fixing groove 183. Thus, the mounting seat 182, the deformation element 192 and the moving element 191 can be connected to each other to form a structural whole, and the rotation of the moving element 191 relative to the mounting seat 182 can also effectively drive the deformation element 192 to stretch.

In some embodiments, the first fixing portion 194 and the second fixing portion 195 are respectively disposed at two ends of the deformation element 192, in other words, two ends of the deformation element 192 are respectively sleeved on the mounting seat 182 and the moving element 191, so that the maximum rotation amount of the moving element 191 relative to the mounting seat 182 can be increased by fully utilizing the structure of the deformation element 192.

Referring to fig. 4, 10 and 11 together, in some embodiments, the mounting seat 182 is provided with a first rotating structure 184 protruding toward the moving element 191, the moving element 191 is provided with a second rotating structure 1913 protruding toward the mounting seat 182, and the mounting seat 182 and the moving element 191 are rotatably connected through the first rotating structure 184 and the second rotating structure 1913. Of course, the rotational connection between the first rotating structure 184 and the second rotating structure 1913 is not limited, and in some embodiments, the power module 18 may further include a rotating element (not shown) that penetrates through the first rotating structure 184 and the second rotating structure 1913, so that the mounting seat 182 and the moving element 191 are rotatably connected. In some embodiments, the rotating element can be a pin, and of course, the mounting seat 182 and the moving element 191 can be rotatably connected by any suitable means such as a hinge connection.

In some embodiments, the mounting seat 182 is provided with two first rotating structures 184 spaced apart from each other, the moving element 191 is provided with two second rotating structures 1913 spaced apart from each other, the two second rotating structures 1913 are located between the two first rotating structures 184, and the two second rotating structures 1913 are in one-to-one correspondence with the two first rotating structures 184, and each second rotating structure 1913 is rotatably connected with a corresponding one of the first rotating structures 184. Thereby, the two sets of the first rotation structure 184 and the second rotation structure 1913 can be mutually limited, so that the rotation of the moving element 191 relative to the mounting seat 182 is more stable.

Further, in some embodiments, the first rotating structure 184 includes a limiting portion 185 and a rotating portion 188 protruded from the limiting portion 185 toward the moving element 191, and the rotating element penetrates through the rotating portion 188 and the second rotating structure 1913, so that the moving element 191 and the mounting seat 182 are rotatably connected. The stopper 185 includes a first stopper surface 186 and a second stopper surface 187 inclined to each other, the rotation of the moving element 191 relative to the mounting seat 182 has two limit positions, and at one limit position of the rotation of the moving element 191 relative to the mounting seat 182, a surface of the second rotating structure 1913 facing the mounting seat 182 abuts against the first stopper surface 186, and at the other limit position of the rotation of the moving element 191 relative to the mounting seat 182, a surface of the second rotating structure 1913 facing the mounting seat 182 abuts against the second stopper surface 187. In other words, the cooperation of the second rotation structure 1913 with the first and second limiting

surfaces

186 and 187 enables the first rotation structure 184 to limit the movement element 191, thereby defining two limit positions of the movement element 191 rotating relative to the mounting seat 182.

As shown in fig. 3 and 10, when the movable element 12 is in the closed state, the movable element 191 is located at one of the limit positions relative to the mounting seat 182, and the second rotation structure 1913 abuts against the first limit surface 186. As shown in fig. 4 and 10, when the movable element 12 is in the open state, the movable element 191 is located at another limit position relative to the mounting seat 182, and the second rotation structure 1913 abuts against the second limit surface 187. It is understood that the angle between the first and second limiting

surfaces

186 and 187 determines the maximum rotation amount of the moving element 191 relative to the mounting seat 182, and the larger the angle between the first and second limiting

surfaces

186 and 187, the maximum rotation amount of the moving element 191 relative to the mounting seat 182 is the largest. The specific angle between the first limiting surface 186 and the second limiting surface 187 can be set according to actual requirements, as long as the two limit positions of the moving element 191 relative to the mounting seat 182 can correspond to the closed state and the open state of the movable element 12, so as to smoothly realize the automatic opening operation of the movable element 12.

In some embodiments, the first rotating structure 184 is disposed on the edge region of the surface of the mounting seat 182 facing the moving element 191, the second rotating structure 1913 is disposed on the edge region of the surface of the moving element 191 facing the mounting seat 182, and the position where the moving element 191 is rotatably connected to the mounting seat 182 is disposed on the edge regions of the two, so that the maximum rotation amount of the moving element 191 relative to the mounting seat 182 can be increased, and mutual interference between the moving element 191 and the mounting seat 182 during rotation can be avoided.

Referring to fig. 4 and 8, in some embodiments, the mounting seat 182 is provided with a water inlet structure 189 protruding toward the fixing seat 181, and the water inlet structure 189 may be a substantially tubular structure. The water inlet structure 189 is communicated with the water inlet space 193 and penetrates through the fixing seat 181, the water inlet structure 189 is partially exposed on one side of the fixing seat 181, which is far away from the mounting seat 182, and the water inlet structure 189 is sleeved with the tap water pipeline 196. Tap water of the municipal water supply network can enter the water inlet space 193 through the tap water pipeline 196 and the water inlet structure 189, and under the hydraulic pressure of the tap water, the moving element 191 rotates relative to the mounting seat 182 in the direction away from the mounting seat 182, so as to drive the transmission element 13 to move, and further drive the moving element 12 to rotate relative to the main body 11 to be opened.

It should be noted that the power module 18 in the present application can be used only for implementing the automatic opening operation of the movable element 12, and the automatic closing operation of the movable element 12 can be implemented by other driving elements such as a motor and a motor. It can be understood that when the power module 18 drives the movable element 12 to switch to the open state, the water inlet space 193 is filled with tap water, and when the movable element 12 is driven by other driving elements to realize an automatic closing operation, the transmission element 13 can drive the moving element 191 to rotate relative to the mounting seat 182 in a direction close to the mounting seat 182, so as to extrude the tap water out of the water inlet space 193.

It should be noted that the power for the power module 18 to drive the movable element 12 to open is derived from the pressure of tap water, and does not mean that the power module 18 of the present application does not need to consume any other energy source such as electric energy during the operation. In some embodiments, the body 180 further has a drainage channel (not shown) communicating with the water inlet space 193, and the connection between the body 180 and the tap water pipe 196 and the drainage channel is provided with an electromagnetic valve. When the movable element 12 needs to be opened, the electromagnetic valve controls the water inlet space 193 to be communicated with the tap water pipeline 196 to block the water inlet space 193 from the water drainage channel, so that tap water enters the water inlet space 193, and the movable element 191 is pushed to rotate relative to the body 180. When the movable element 12 needs to be covered, the electromagnetic valve blocks the water inlet space 193 from the tap water pipeline 196, and controls the water inlet space 193 to be communicated with the drainage flow channel, so that tap water can be discharged from the drainage flow channel.

Through the design to power module 18 structure, control element such as cooperation solenoid valve can realize the automation of movable element 12 and open the operation, for the setting that traditional motor drive movable element 12 opened, solenoid valve power consumption is showing and is reducing to reach energy-conserving effect. Furthermore, because the solenoid valve has low power consumption and can be powered by a battery or other power storage elements, the power module 18 can also normally operate in a power failure state, so that the automatic opening operation of the movable element 12 is more stable and reliable.

It can be understood that, when tap water enters the water inlet space 193 of the power module 18, the power module 18 can drive the movable element 12 to rotate relative to the main body 11 to switch to the open state. When the movable element 12 needs to be switched from the open state to the closed state, the tap water in the power module 18 needs to be drained. The power source for switching the movable element 12 from the open state to the closed state may be derived from the power module 18 itself, or from other driving structures such as a motor or a motor of the toilet 10. In the process of switching the movable element 12 from the open state to the closed state, tap water in the power module 18 needs to be discharged gradually, and when the water discharge is started, the volume of the tap water in the power module 18 is large, so that excessive impact is easily generated on the pipeline or the driving element of the toilet bowl 10, and the pipeline or the driving element is damaged. To solve this problem, a segmented damping method is provided below.

A sectional damping method is used for increasing the drainage capacity of a toilet 10 to tap water in a power module 18 when the tap water capacity in the power module is large, so that the impact of the tap water to a pipeline, a driving element and other components is reduced, meanwhile, the load of the driving element can be reduced, and the service life of the driving element is prolonged. In some embodiments, the segmented damping method comprises the steps of:

a first drain passage and a second drain passage are provided, the instantaneous water discharge of the first drain passage being greater than the instantaneous water discharge of the second drain passage. It is understood that the first drain passage having a larger instantaneous water discharge amount has a larger water discharge capacity than the second drain passage, in other words, the first drain passage has a larger water discharge amount than the second drain passage in the same period of time. In this case, the means for making the instantaneous water discharge amount of the first water discharge channel larger than the instantaneous water discharge amount of the second water discharge channel is not limited, and for example, the first water discharge channel may be constituted by a plurality of sub-channels, the number of sub-channels in the first water discharge channel is larger than the number of sub-channels in the second water discharge channel, or the inner diameter of the first water discharge channel is larger than the inner diameter of the second water discharge channel, or the like.

The movable element 12 is switched from the open state to the closed state to allow the power module 18 to begin draining.

And draining water through the first drainage channel.

And discharging water through the second water discharge channel.

According to the sectional damping method, in the drainage process of the power module 18, water is drained through the first drainage channel with large instantaneous drainage amount, so that the drainage capacity is improved when the tap water capacity in the power module 18 is large, the load of the driving element for driving the movable element 12 to cover is reduced, the impact of the tap water on the pipeline and the driving element can be reduced, and the pipeline and the driving element are prevented from being damaged. When the volume of tap water discharged into the water inlet channel through the first water discharge channel is less, for example, when the volume is half of the volume of the movable element 12 in the open state, the second water discharge channel with less instantaneous water discharge is used instead, so that the situation that the covering speed of the movable element 12 is accelerated due to the fact that the water discharge speed is too high when the volume of the tap water is less can be avoided. This is advantageous in that the speed of the entire closing process of the movable element 12 is relatively even, and the movable element 12 is prevented from impacting the main body 11 due to too high speed.

The arrangement of the first and second drainage channels in different embodiments is provided below, and further arrangements can be derived by referring to the disclosure of the present application, as long as segmented damping is achieved to allow the toilet 10 to have different drainage capabilities for the power module 18 at different stages.

In some embodiments, in the step of providing the first drain passage and the second drain passage, a first pipe and a second pipe are provided. Wherein, first pipeline and second pipeline constitute first drainage passageway jointly, and first pipeline constitutes second drainage passageway alone. Of course, the relation of the instantaneous water displacement of the first pipe and the second pipe is not limited as long as the instantaneous water displacement of the first drain passage is made larger than that of the second drain passage.

In this embodiment, in the step of draining water through the first drain passage, the draining is simultaneously performed through the first pipe and the second pipe. And in the step of draining water through the second drainage channel, the second pipeline is blocked, and water is drained through the first pipeline alone.

Further, in some embodiments, the instantaneous displacement of the first conduit is less than the instantaneous displacement of the second conduit. Therefore, the drainage capacity of the power module 18 when the tap water volume is small can be effectively limited, the rotating speed of the movable element 12 when the movable element 12 rotates to be close to the main body 11 is further reduced, and the movable element 12 or the main body 11 is prevented from being damaged due to collision between the movable element 12 and the main body 11.

In other embodiments, in the step of providing the first and second drain passages, a first pipe and a second pipe are provided, and an instantaneous water discharge amount of the first pipe is smaller than an instantaneous water discharge amount of the second pipe. For example, the caliber of the first conduit is smaller than the caliber of the second conduit.

In this embodiment, in the step of draining water through the first drain passage, water is drained through the second pipe. In the step of discharging water through the second drain passage, water is discharged through the first pipe. It can be understood that the second pipeline forms the first drainage channel, the first pipeline forms the second drainage channel, and the instantaneous drainage quantity of the first drainage channel is larger than that of the second drainage channel through the difference design of the calibers.

In still other embodiments, in the step of providing the first drain passage and the second drain passage, a drain passage is provided. Wherein, drainage channel includes first section and the second section of intercommunication each other, and the instantaneous displacement of first section is greater than the instantaneous displacement of second section. For example, the bore of the first section is larger than the bore of the second section. The first section forms a first drain passage and the second section forms a second drain passage.

In the step of discharging water through the first drain passage, water is discharged through the first section.

In the step of draining water through the second drain channel, water is drained through the second section.

Specifically, the first drainage channel and the second drainage channel may be respectively formed by two connected sections in one pipe, and during drainage, tap water flows from one end of the first section, which is far away from the second section, to one end of the second section, which is far away from the first section, so that the first drainage channel can be switched to the second drainage channel at a junction of the first section and the second section. So set up, the switching of first drainage channel to second drainage channel can be formed by the structural design of drainage channel itself among the drainage process, and need not the manual work or switch through the electric drive, is favorable to saving the running cost.

In some embodiments, the above-mentioned segmented damping method further comprises the steps of:

a drive element is provided.

In the step of draining water through the first drain passage, the liquid in the inlet water space 193 is driven out of the first drain passage by the driving member.

In the step of draining water through the second drainage channel, the liquid in the intake volume 193 is driven out of the second drainage channel by the driving element.

Specifically, the driving element may be connected to the movable element 12, the driving element drives the movable element 12 to rotate relative to the main body 11 to switch from the open state to the closed state, and the movable element 12 drives the power module 18 to drain water during the rotation process. The driving element can provide power for the whole process of the covering of the movable element 12, and the driving element can also only provide acting force for the movable element 12 to enable the movable element 12 to rotate relative to the main body 11 to cross the vertical line, so that the movable element 12 can fall under the action of gravity to be switched to the covering state.

For example, in some embodiments, in the step of draining water through the first drainage channel, the driving element drives the movable element 12 to rotate relative to the main body 11 until the vertical line is crossed, and the movable element 12 drives the liquid in the water inlet space 193 to be drained.

In the step of discharging water through the second water discharge passage, the movable member 12 rotates relative to the body 11 by gravity, and the movable member 12 drives the liquid in the water inlet space 193 to be discharged. Therefore, when the driving element drives the movable element 12 to drain, the drainage capacity of the power module 18 can be improved, so that the load of the driving element is reduced, and the driving element is prevented from being damaged. When the movable element 12 falls under the action of gravity, the drainage capacity of the power module 18 can be reduced, and the movable element 12 is prevented from impacting the main body 11 due to the fact that the speed of the movable element 12 is too high under the action of gravity.

Of course, the above description only exemplifies the application scenario of the segmented damping method in some embodiments, and actually, the segmented damping method may also be used in other sanitary equipment or in other scenarios requiring drainage, as long as the application of the segmented damping method can reduce the risk of damage to components such as pipes and driving elements.

Referring to fig. 1, 12, 13 and 14, the present application further provides a valve assembly 20, wherein the valve assembly 20 integrates various valves to achieve diversified functions. Specifically, in some embodiments, the valve assembly 20 integrates a segmented damping valve that includes a valve body 21 and a flow restriction element 30. The valve body 21 has a water outlet 212 communicating with the water inlet space 193 of the power module 18 and a water outlet 211 communicating with the water tank 17 of the toilet 10. The valve body 21 is provided with a drain passage 214, and the drain passage 214 includes a first section 215 and a second section 216 communicating with each other, and the first section 215 and the second section 216 are arranged in order in a direction in which the water outlet 212 flows to the drain port 211. Wherein the instantaneous water displacement of the first section 215 is greater than the instantaneous water displacement of the second section 216. A flow restriction element 30 is slidably disposed within the drain passage 214, the flow restriction element 30 being positioned to correspond to an end of the first segment 215 distal from the second segment 216, the flow restriction element 30 further having a flow restriction orifice 31, the flow restriction orifice 31 being positioned to correspond to the second segment 216.

It will be appreciated that when the power module 18 is drained, tap water flows from the power module 18 through the drain passage 214 from the water outlet 212 and then into the water tank 17, and when flowing through the drain passage 214, tap water flows into the drain passage 214 from the end of the first section 215 remote from the second section 216, sequentially flows through the first section 215 and the second section 216 and then flows out of the drain passage 214 from the end of the second section 216 remote from the first section 215. When tap water flows from the end of the first section 215 remote from the second section 216 into the drain 214, the restriction 30 is pushed to move along the drain 214 in a direction towards the second section 216, and during the movement of the restriction 30, the tap water fills the space on the side of the restriction 30 facing away from the second section 216. At this point, it can be understood that the power module 18 is draining through the first section 215 of the drain passage 214. Referring to fig. 14, when the restriction 30 moves along the drain passage 214 to the end of the second section 216 near the first section 215 and cannot move any further, the position of the restriction hole 31 corresponds to the second section 216, and the tap water flows through the restriction hole 31, passes through the restriction 30, and then flows out of the drain passage 214 through the second section 216. At this point, it can be appreciated that the power module 18 is draining through the second section 216 of the drain passage 214.

Thus, the sectional damping valve in the present embodiment can implement the sectional damping method described above, in which the first section 215 constitutes the first drain passage 214 in the sectional damping method described above, and the second section 216 constitutes the second drain passage 214 in the sectional damping method described above. Therefore, the sectional damping valve can reduce the load of the driving element and the impact of tap water on the pipeline and the driving element, thereby being beneficial to reducing the risk of damage to the driving element, the pipeline and other components.

In some embodiments, the radial dimension of the first section 215 is greater than the radial dimension of the second section 216 such that the instantaneous displacement of the first section 215 is greater than the instantaneous displacement of the second section 216.

In some embodiments, the staged damping valve further includes an elastic element 33, the elastic element 33 is provided on a side of the flow restriction element 30 facing the second stage 216, and both ends of the elastic element 33 abut against the inner wall surface of the valve body 21 and the flow restriction element 30, respectively. Thus, during the draining process of the power module 18, when the tap water pushes the flow restriction element 30 to move toward the second section 216, the flow restriction element 30 and the valve body 21 compress the elastic element 33. When the power module 18 finishes draining, the tap water no longer exerts the acting force directed from the flow restriction element 30 to the second section 216 on the flow restriction element 30, and the flow restriction element 30 can return to the position where the first section 215 is far away from the second section 216 under the elastic restoring force of the elastic element 33, so as to achieve the effect of sectional damping when the power module 18 drains next time. In some embodiments, the elastic element 33 may be any suitable elastically deformable member such as a spring, rubber, or the like.

Referring to fig. 15 and 16 together, in some embodiments, the flow restriction element 30 includes a water stop portion 32 and a snap structure connected to each other, and the snap structure may be formed by protruding a side of the water stop portion 32 facing the elastic element 33. Specifically, the clamping structure includes a connecting portion 322 and a clamping portion 323 that are connected to each other, the connecting portion 322 is fixedly connected to one side of the water blocking portion 32 facing the second segment 216, the clamping portion 323 is disposed at an end of the connecting portion 322 that is far away from the water blocking portion 32, and is spaced from the water blocking portion 32, and the elastic element 33 is clamped between the clamping portion 323 and the water blocking portion 32. For example, the elastic member 33 may be a spring, and a ring-shaped structure of the elastic member 33 closest to the water stopper 32 is located between the snap-in portion 323 and the water stopper 32.

Further, in some embodiments, the limiting element 38 is provided with a plurality of clamping structures, the plurality of clamping structures are arranged at intervals along the circumference of the water blocking portion 32, and the circumference of the clamping portion 323 is located outside the circumference of the connecting portion 322, in other words, the clamping portion 323 is located on a side of the connecting portion 322, which faces away from the central axis of the water blocking portion 32. The elastic element 33 is clamped between the plurality of clamping portions 323 and the water blocking portion 32 in a ring-shaped structure closest to the water blocking portion 32, so that the elastic element 33 and the limiting element 38 can be effectively fixed.

In some embodiments, the water stop 32 has a groove 321 on a side facing the second section 216, and the snap-fit structure is disposed within the range of the groove 321, which is beneficial to reduce the axial dimension of the limiting element 38 and to protect the snap-fit structure. In some embodiments, the water stop 32 may be a one-piece structure, and as shown in fig. 13, in some embodiments, the water stop 32 may also be composed of two members, wherein one member wraps a portion of the other member, and the portion of the other member that is not wrapped correspondingly forms the groove 321.

Referring to fig. 14, 17 and 18, in some embodiments, the valve body 21 includes a first valve structure 22 and a second valve structure 23, the second valve structure 23 includes a plate body 230 and a first engaging portion 232 protruding from the plate body 230 toward the first valve structure 22, and the first engaging portion 232 is engaged in the first valve structure 22 to form a first section 215 surrounded by the first valve structure 22. The first fitting portion 232 is also used for abutting against the flow restriction element 30, specifically, when the flow restriction element 30 moves to the end of the first section 215 close to the second section 216 along the drainage channel 214, the water blocking portion 32 abuts against the end surface of the first fitting portion 232, so that the flow restriction element 30 can not move any more in the direction close to the second section 216.

In some embodiments, the second valve structure 23 further includes a channel portion 233 protruding from the plate body 230 toward the first valve structure 22, the channel portion 233 being disposed inside the first fitting portion 232, and the second segment 216 being disposed inside the channel portion 233. When the flow restriction element 30 moves along the drainage channel 214 to abut against the first fitting portion 232, the flow restriction hole 31 corresponds to the port of the channel portion 233, and the tap water enters the channel portion 233 through the flow restriction hole 31.

In some embodiments, the outer peripheral surface of the first fitting portion 232 is in sealing connection with the inner peripheral surface of the first valve structure 22. For example, the valve assembly 20 may further include a plurality of rings of the first sealing ring 34, the first sealing ring 34 is disposed between the outer circumferential surface of the first fitting portion 232 and the inner circumferential surface of the first valve structure 22, and the plurality of rings of the sealing ring are spaced along the axial direction of the passage portion 233 to improve the sealing performance between the first fitting portion 232 and the first valve structure 22.

In some embodiments, an end of the elastic element 33 away from the limiting element 38 is located between the first engaging portion 232 and the channel portion 233, and is sleeved on an outer circumferential surface of the channel portion 233. Therefore, the channel part 233 can also limit the elastic deformation path of the elastic element 33, and the elastic element 33 is not easy to separate from the channel part 233, so as to improve the stability of the operation of the sectional damping valve.

In some embodiments, the valve body 21 further has an outlet hole 231, and the position of the outlet hole 231 corresponds to an end of the second section 216 away from the first section 215, for example, the outlet hole 231 is disposed on a portion of the plate body 230 corresponding to an inner side position of the channel portion 233. Also, the instantaneous discharge amount of the nozzle hole 231 is smaller than that of the second section 216, for example, the aperture of the nozzle hole 231 is smaller than the inner diameter of the passage portion 233. Therefore, the drainage capacity of the water outlet hole 231 is weaker than that of the second section 216, when the power module 18 drains water through the second section 216 until the tap water flows to the water outlet hole 231, the water outlet hole 231 can further limit the drainage rate of the power module 18, so that the rotating speed of the movable element 12 is further reduced when the movable element 12 rotates to a position close to the main body 11, and the movable element 12 can be prevented from impacting the main body 11 due to the fact that the speed of the movable element 12 is too high.

In some embodiments, the instantaneous displacement of the flow restriction orifice 31 is less than the instantaneous displacement of the second segment 216. For example, the orifice 31 has a smaller bore diameter than the inner diameter of the passage portion 233. Thus, while water is drained through the first stage 215, that is, while tap water pushes the stopper element 38 to move in a direction approaching the passage portion 233, tap water does not easily flow from the restrictor hole 31 to the second stage 216, but when the stopper element 38 moves to abut against the first fitting portion 232, tap water flows from the restrictor hole 31 to the second stage 216, and water is drained through the second stage 216. So set up, can make the sectional damping valve give full play to the effect of sectional damping to effectively reduce the impact of running water to pipeline and drive element.

It will be understood that the toilet 10 described above uses tap water as a power source to drive the movable element 12 to open, and when the movable element 12 is not subjected to other external forces, such as other driving elements like motors, etc., or manual force, the rotation speed of the movable element 12 during opening depends on the water pressure of the tap water. When the movable element 12 is affected by other external forces to increase its rotation speed, for example, during the process of opening the movable element 12 by the power module 18, when the movable element 12 is manually lifted, the flowing speed of the tap water into the power module 18 cannot keep up with the opening speed of the movable element 12, which may cause the water inlet space 193 of the power module 18 to form a vacuum.

Specifically, when the water inlet space 193 of the power module 18 is filled with water, the power module 18 drives the movable element 12 to open relative to the movable element 12 at a first speed, and when the movable element 12 is subjected to an unexpected force except the power module 18, so that the opening speed of the movable element 12 relative to the main body 11 is higher than the first speed, a vacuum is generated in the water inlet space 193. Of course, when the movable element 12 is in the closed state, if the power module 18 does not drive the movable element 12 to open, and the movable element 12 is lifted manually or driven by a driving element, the water inlet space 193 of the power module 18 is also vacuumed. When the power module 18 forms a vacuum, if the external force disappears, for example, the hand leaves the movable element 12, or the driving element stops applying force to the movable element 12, due to the existence of the vacuum attraction force, the power module 18 will drive the movable element 12 to rebound toward the main body 11, so that the movable element 12 will easily hit the main body 11, thereby generating noise and even damaging the movable element 12 or the main body 11.

To solve the above problem, referring to fig. 1 and 15, in some embodiments, the valve assembly 20 further integrates a one-way communication assembly that connects the water tank 17 and the power module 18 and is capable of one-way communication in the direction of the water tank 17 flowing to the power module 18. For example, the one-way conduction component can communicate the water outlet 211 and the water outlet 212 and can conduct in one direction in the direction that the water outlet 211 flows to the water outlet 212.

Therefore, when the movable element 12 is lifted by an external force to cause a vacuum to be formed in the power module 18, the vacuum adsorption force generated by the power module 18 can suck tap water in the water tank 17 through the one-way conduction assembly, so that the tap water sequentially flows into the power module 18 through the water outlet 211, the one-way conduction assembly and the water outlet 212, fills the water inlet space 193 of the power module 18, and the vacuum is not formed in the power module 18. Therefore, when the external force is removed, the movable element 12 does not bounce against the body 11 to hit the body 11 because no vacuum is formed in the power module 18. Furthermore, the one-way conduction assembly blocks the passage of the power module 18 flowing to the water tank 17 through the one-way conduction assembly, so that the operation of the power module 18 is not affected by the arrangement of the one-way conduction assembly, and the stability of the toilet 10 is improved.

Referring also to fig. 19-23, in some embodiments, the one-way conducting assembly includes a one-way pipe 36 and a one-way conducting structure 37, wherein two ends of the one-way pipe 36 are respectively communicated with the water tank 17 and the power module 18, for example, two ends of the one-way pipe 36 are respectively communicated with the water outlet 212 and the water outlet 211. The one-way conduction structure 37 is arranged in the valve body 21 and corresponds to the port position of the one-way pipeline 36 so as to realize the one-way conduction function.

Specifically, in some embodiments, the valve assembly 20 further includes a limiting element 38, the valve body 21 is provided with the slot 24, the one-way conducting structure 37 is arranged in the slot 24, the limiting element 38 is fixedly connected with the valve body 21 and seals the slot opening of the slot 24, and the limiting element 38 is further communicated with the slot 24 and the one-way pipe 36. Specifically, in some embodiments, the central portion of the restriction element 38 is perforated, and a side of the restriction element 38 facing away from the slot 24 is protruded with a hollow tubular structure (not shown) corresponding to the perforation, the hollow tubular structure communicating with the port of the one-way pipe 36, thereby communicating the one-way pipe 36 and the slot 24.

It can be understood that, in the present embodiment, the one-way conduction structure 37 is provided in the valve body 21 and located between the water outlet 212 and the one-way pipe 36, and the one-way conduction structure 37 corresponds to the port position of the one-way pipe 36.

Further, in some embodiments, the slot 24 of the valve body 21 has a bottom surface, and the valve body 21 is further provided with a hole structure 25 penetrating through the bottom surface, wherein the hole structure 25 is communicated with the water outlet 212 and the slot 24, i.e., the water inlet space 193 of the power module 18 is communicated with the slot 24. In some embodiments, the valve body 21 further includes a plurality of spacers 26 protruding from the bottom surface toward the one-way communication structure 37, the spacers 26 are spaced apart from each other on the bottom surface, and a gap communicating the slot 24 and the hole structure 25 is formed between the spacers 26.

In some embodiments, the one-way conduction structure 37 is a flat plate structure, for example, the one-way conduction structure 37 is substantially in a circular cake shape, and the one-way conduction structure 37 is movably disposed in the slot 24 along the axial direction of the limiting element 38. It can be understood that, when the one-way conduction structure 37 moves in the slot 24 to abut against the limiting element 38, the one-way conduction structure 37 blocks the opening of the limiting element 38 to block the slot 24 and the one-way pipe 36; when the one-way conduction structure 37 moves in the slot 24 to abut against the side of the spacing structure 26 opposite to the bottom surface, the hole structure 25, the slot 24 and the one-way pipe 36 are in a conduction state due to the existence of the gap between the spacing structures 26. Therefore, when the power module 18 operates to drive the movable element 12 to open, due to the structure of the communication hole 1910 and the slot 24 of the power module 18, the water pressure of tap water can drive the one-way communication structure 37 to abut against the limiting element 38, so that the one-way pipeline 36 and the power module 18 are blocked. When the movable element 12 is lifted up by hand or by driving of a driving element, the vacuum suction force formed in the power module 18 will suck the one-way conducting structure 37 to the one-way conducting structure 37 against the spacer structure 26 to conduct the one-way pipe 36 and the power module 18, so that the power module 18 can suck tap water from the water tank 17 through the one-way pipe 36. The valve assembly 20 realizes the function of one-way communication of the water tank 17 towards the direction of the power module 18 through the cooperation of the one-way communication structure 37, the spacing structure 26 and the limiting element 38.

In some embodiments, a plurality of spacing structures 26 are circumferentially disposed around the aperture structure 25. Further, in some embodiments, the inner sides of the plurality of spacing structures 26 are all flush with the edge of the aperture structure 25. For example, the sides of the plurality of spacers 26 facing the axis of the hole structure 25 together form a circumference which is exactly flush with the contour of the hole structure 25. Therefore, the conduction efficiency of the one-way pipeline 36 and the power module 18 can be improved, and the vacuum adsorption force of the power module 18 can smoothly suck tap water from the water tank 17 through the one-way pipeline 36.

In some embodiments, the spacer structure 26 includes a first spacer 261 and a second spacer 262, the first spacer 261 and the second spacer 262 being interconnected adjacent an end of the aperture structure 25 and forming an inner side of the spacer structure 26. Moreover, in two adjacent spacer structures 26, the first spacers 261 of one spacer structure 26 are disposed opposite to the second spacers 262 of the other spacer structure 26, in other words, the first spacers 261 and the second spacers 262 are sequentially staggered in the circumferential direction of the hole structure 25. Gaps communicating the slots 24 and the hole structures 25 are formed between the first and

second spacers

261 and 262 facing each other in two adjacent spacer structures 26. Set up a plurality of interval structures 26 and form a plurality of clearances, be favorable to promoting the efficiency that one-way pipeline 36 and power module 18 switched on, further guarantee that the vacuum adsorption ability that power module 18 formed can effectively follow the suction running water in the water tank 17.

In some embodiments, the sides of the plurality of spacing structures 26 facing away from the bottom surface are flush, so that the one-way conduction structure 37 is favorably and smoothly abutted against the side of the spacing structure 26 facing away from the bottom surface, and the one-way conduction structure 37 is prevented from deflecting to affect the conduction of the power module 18 and the one-way pipe 36.

Referring again to fig. 1, 13, 14 and 15, the valve assembly 20 is further integrated with other components, specifically, in some embodiments, the valve body 21 is further provided with a water inlet 210, and tap water can enter the valve body 21 from the water inlet 210, for example, the water inlet 210 can be communicated with a municipal water supply network. The water outlet 212 of the valve body 21 is communicated with the water inlet space 193 of the power module 18, and the water outlet 211 is communicated with the water tank 17. The valve body 21 is further provided with a water inlet passage 213 communicating the water inlet 210 and the water outlet 212, a water discharge passage 214 communicating the water discharge port 211, and a pressure relief passage 217 communicating the water discharge port 211. The valve assembly 20 further includes a first valve element 39, a second valve element 40, and a pressure relief structure 41, the first valve element 39 being connected to the valve body 21 and serving to open or block the water inlet passage 213. The second valve element 40 is connected to the valve body 21 and serves to open or block the water outlet 212 and the drain passage 214. The pressure relief structure 41 is disposed in the pressure relief channel 217 and blocks the pressure relief channel 217 and the water outlet 212, and the pressure relief structure 41 can move in the pressure relief channel 217 to conduct the pressure relief channel 217 and the water outlet 212.

It will be appreciated that the valve assembly 20 described above can be used in the toilet 10 described above in which the power module 18 is configured. In the toilet 10, when the movable element 12 needs to be opened, that is, the movable element 12 is switched from the closed state to the open state, the first valve element 39 is driven to conduct the water inlet channel 213, and the second valve element 40 is driven to block the water outlet 212 and the water discharge channel 214, so that tap water flows from the water inlet 210 to the water outlet 212 through the water inlet channel 213, and then enters the power module 18, and the water pressure of the tap water provides a power source for the power module 18, so that the power module 18 can drive the movable element 12 to open. When the movable element 12 needs to be closed, that is, the movable element 12 is switched from the open state to the closed state, the first valve element 39 is driven to block the water inlet channel 213, and the second valve element 40 is driven to conduct the water outlet 212 and the water discharge channel 214, so that the tap water in the power module 18 is discharged from the water outlet 212 to the water outlet 211 through the water discharge channel 214, and then enters the water tank 17. Of course, during the draining process of power module 18, tap water may also be drained directly from drain 211 to a sewer or other means for storing liquid.

Furthermore, through setting up pressure relief structure 41 and pressure relief passageway 217, in the water intaking or the drainage process of power module 18, if the running water pressure in valve body 21 is too big, the running water can promote pressure relief structure 41 and remove along pressure relief passageway 217 and switch on pressure relief passageway 217, delivery port 212 and water inlet 210, thereby make partial running water can discharge from outlet 211 through pressure relief passageway 217, with the water pressure of reducing the running water in valve body 21, avoid the water pressure in valve body 21 too big and produce too big impact to components such as valve element in valve body 21 and the valve body 21, effectively reduce the risk that valve assembly 20 damaged.

Above-mentioned valve module 20 integrates a plurality of components such as first valve element 39, second valve element 40, pressure relief structure 41 and one-way conduction subassembly, on the basis of realizing the multiple functions such as the intaking of power module 18, drainage, pressure release and follow through one-way pipe 36 from the water tank 17 suction running water, still is favorable to compressing the volume of valve module 20, reduces the occupation space of valve module 20 in closestool 10, and then is favorable to promoting the space utilization of closestool 10.

As shown in fig. 13, 17 and 18, in some embodiments, the second valve structure 23 further includes a second engaging portion 27 protruding from the plate portion 230 toward the first valve structure 22, and the second engaging portion 27 is spaced apart from the first engaging portion 232. The first fitting portion 232 is fitted into the first valve structure 22 to surround the first valve structure 22 to form the drain passage 214, and the second fitting portion 27 is fitted into the first valve structure 22 to surround the first valve structure 22 to form the relief passage 217.

In some embodiments, the first valve structure 22 further has a pressure relief port 218 communicating with the pressure relief channel 217 and the water outlet 212, and it is understood that the pressure relief port 218 can also communicate with the water inlet 210, so that the pressure relief structure 41 can perform a pressure relief function for both the water inlet process and the water outlet process of the power module 18. In some embodiments, pressure relief structure 41 blocks pressure relief vent 218 to block pressure relief channel 217 and outlet 212.

Further, in some embodiments, the valve assembly 20 further includes an elastic structure 42, the elastic structure 42 is disposed in the pressure relief channel 217, and two ends of the elastic structure 42 abut against the pressure relief structure 41 and the second fitting portion 27, respectively. The elastic structure 42 may be made of the same material as the elastic element 33, and the pressure relief structure 41 may be substantially shaped like a circular cake. When the water pressure of the tap water is too high, the tap water pushes the pressure relief structure 41 to move in a direction away from the pressure relief opening 218, when the pressure relief structure 41 leaves the pressure relief opening 218, the pressure relief channel 217 is communicated with the water outlet 212 through the pressure relief opening 218, and part of the tap water is discharged from the water outlet 211 through the pressure relief channel 217, in this process, the pressure relief structure 41 compresses the elastic structure 42. When the water pressure in the first valve structure 22 decreases, the elastic restoring force of the elastic structure 42 can drive the pressure relief structure 41 to move toward the pressure relief opening 218 until the pressure relief opening 218 is sealed again, so as to block the pressure relief channel 217 and the water outlet 212.

In some embodiments, an end of the elastic structure 42 away from the pressure relief structure 41 is sleeved on an outer peripheral surface of the second engaging portion 27. Therefore, the second fitting portion 27 can also limit the elastic structure 42, and prevent the elastic structure 42 from deflecting, thereby improving the stability of the operation of the pressure relief structure 41. In some embodiments, an end of the elastic structure 42 away from the second engaging portion 27 may be further sleeved on a portion of the pressure relief structure 41 protruding toward the second engaging portion 27, so as to further improve the stability of the operation of the elastic structure 42.

In some embodiments, the outer peripheral surface of the second fitting portion 27 is in sealing connection with the inner peripheral surface of the first valve structure 22. Further, in some embodiments, a plurality of second sealing rings 35 are further disposed between the outer circumferential surface of the second fitting portion 27 and the inner circumferential surface of the first valve structure 22, and the plurality of second sealing rings 35 are disposed at intervals along the axial direction of the second fitting portion 27 to improve the sealing effect between the second fitting portion 27 and the first valve structure 22.

In some embodiments, the valve assembly 20 further includes a drain conduit 29, the drain conduit 29 is disposed on a side of the plate body 230 facing away from the first valve structure 22, and the drain conduit 29 communicates with the pressure relief channel 217, the drain channel 214, and the drain port 211. For example, the drain pipe 29 may have a hollow pipe structure with one end opened, and the port of the drain pipe 29 corresponds to the drain port 211, or the port of the drain pipe 29 forms the drain port 211. The plate body 230 is opened at a position corresponding to the drain passage 214 to communicate the drain passage 214 with the drain pipe 29, for example, a middle portion of the drain pipe 29 communicates with the outlet hole 231. The plate body 230 is opened at a position corresponding to the relief passage 217 to communicate with the relief passage 217 and the drain pipe 29, for example, a side wall of the closed end of the drain pipe 29 communicates with the relief passage 217, that is, a position corresponding to the second fitting portion 27. With such an arrangement, the drainage channel 214, the pressure relief channel 217 and the water outlet 211 can be communicated through one drainage pipeline 29, and the drainage channel 214 and the pressure relief channel 217 cannot interfere with each other, which is beneficial to improving the operation efficiency and the space utilization rate of the valve assembly 20, thereby further reducing the occupied space of the valve assembly 20.

Referring to fig. 12, 14 and 15, in some embodiments, the one-way pipe 36 is disposed outside the valve body 21, and two ends of the one-way pipe 36 are connected to the drain pipe 29 and the valve body 21, respectively, for example, a sub-pipe connected to the one-way pipe 36 is extended from the middle of the drain pipe 29. In some embodiments, the communication between the one-way conduit 36 and the drain conduit 29 corresponds to the location of the outlet hole 231, which facilitates further optimizing the space utilization of the valve assembly 20.

Further, as shown in fig. 12, fig. 19 and fig. 20, in some embodiments, the valve body 21 has a first surface 281 and a second surface 282 that are opposite to each other, and the valve body 21 further includes a first side surface 283, a second side surface 284 and a third side surface 285 that connect the first surface 281 and the second surface 282, wherein the first side surface 283, the second side surface 284 and the third side surface 285 are sequentially connected in a circumferential direction of the valve body 21. In the present embodiment, the valve body 21 has a substantially rectangular parallelepiped shape, and the first surface 281, the second surface 282, the first side 283, the second side 284, and the third side 285 are only virtual planes introduced for convenience of describing features of the valve body 21 on each side, and actually, the surface of the valve body 21 on each side may be uneven.

In some embodiments, the water inlet 210 is disposed on the first side 283 of the valve body 21, the first valve element 39 is inserted into the valve body 21 on the second side 284, the water outlet 212 is disposed on the first surface 281, and the limiting element 38 is disposed on the first surface 281, i.e., one end of the one-way pipe 36 is connected to the water outlet 212 and disposed adjacent to the limiting element 38. Thus, the positions of the water inlet 210, the first valve element 39 and the water outlet 212 are closer to each other, which is favorable for reducing the space occupied by the water inlet channel 213 in the valve body 21 and increasing the space utilization of the valve assembly 20, and is also favorable for the first valve element 39 to effectively block or communicate the water inlet channel 213. Furthermore, the one-way conduction structure 37 is disposed adjacent to the water outlet 212, so that a conduction path between the one-way pipe 36 and the water outlet 212 can be shortened, and the flowing speed between the one-way pipe 36 and the power module 18 is increased, thereby ensuring that the power module 18 can effectively extract tap water from the water tank 17 through the one-way pipe 36 when vacuum is formed.

In some embodiments, the second valve element 40 is inserted into the valve body 21 at the third side surface 285, and the pressure relief passage 217 is disposed adjacent to the first side surface 283 and the drain passage 214 is disposed adjacent to the third side surface 285 in a direction perpendicular to the first side surface 283 and the third side surface 285. Therefore, the pressure relief channel 217 is arranged closer to the water inlet 210 and the water outlet 212, so that effective pressure relief effect can be achieved on water inlet and outlet of the power module 18, meanwhile, the second valve element 40 cannot interfere with the first valve element 39, the one-way pipeline 36 and other components, and the second valve element 40 is favorable for effectively blocking or conducting the water outlet 212 and the drainage channel 214.

In some embodiments, both first valve element 39 and second valve element 40 may be solenoid valves.
