[0078] As Figures 1-4 shown, Figures 1-4 A water inlet assembly 100 of a toilet in the present application is shown. The water inlet assembly 100 comprises a filter support 1, a filter assembly, a first valve 2 and a second valve 3.

[0079] As Figure 6 , 7 shown, the filter support 1 is provided with a first water inlet 111, a first water outlet 112 and a second water outlet 113. The first water inlet 111 is used to connect with a water supply pipe of tap water. The filter support 1 is provided with a water path connecting the first water inlet 111 and the first water outlet 112.

[0080] As shown in Figure 4 , 11 , 12, the first valve 2 can be a single pulse valve. The first valve 2 is provided with a water inlet 21 and a water outlet 22. The first valve 2 is connected to the filter support 1. The water inlet 21 of the first valve 2 is communicated with the first water outlet 112 of the filter support 1. The water outlet 22 of the first valve 2 is used to connect the rim jet. The first valve 2 can open and close the first water outlet 112 of the filter support 1. The first water outlet 112 of the filter support 1 can supply water to the rim jet of the toilet bowl. The rim jet is used to flush the bowl of the toilet.

[0081] As shown in Figure 4 , 5 , 7, the filter assembly includes a first filter assembly 4 and a second filter assembly 5. The first filter assembly 4 can filter water. The first filter assembly 4 is installed on the filter support 1. The first filter assembly 4 is provided with a filter inlet 4111 and a filter outlet 4112. The filter inlet 4111 is communicated with the first water inlet 111.

[0082] As shown in Figure 7 , 9 , 10, 13, the second valve 3 can be an electromagnetic valve. The second valve 3 is connected to the filter support 1. The second valve 3 is provided with a water inlet 31 and a water outlet 32. The water inlet 31 of the second valve 3 is connected to the filter outlet 4112 of the first filter assembly 4.

[0083] As shown in Figure 4 , 5 , 7, the second filter assembly 5 can filter water. The second filter assembly 5 is installed on the filter support 1. The second filter assembly 5 is provided with a scale inhibition inlet 512 and a scale inhibition outlet 513. The scale inhibition inlet 512 is communicated with the water outlet 32 of the second valve 3. The scale inhibition outlet 513 is communicated with the second water outlet 113 of the filter support 1.

[0084] The second water outlet 113 is used to supply water to the body washing assembly and the foam generating assembly of the toilet. The body washing assembly is used to flush the vulva and buttocks, etc. The foam generating assembly is used to generate foam and deliver the foam to the bowl. The foam has the functions of preventing water splashing and cleaning the bowl and preventing odor.

[0085] In this way, as shown in Figure 6 , when the first valve 2 is opened, water flows from the first water inlet 111 into the filter support 1, and then is output from the first water outlet 112 of the filter support 1, which can supply water to the rim jet of the toilet, thereby flushing the toilet. When the first valve 2 is closed, the first water outlet 112 no longer outputs water. As shown in Figure 7As shown, when the second valve 3 is opened, water can flow through the first water inlet 111 of the filter support 1, the first filter assembly 4, the second valve 3, the second filter assembly 5, the second water outlet 113 of the filter support 1 in sequence, and be delivered to the human body cleaning assembly and the foam generating assembly through the second water outlet 113. When the second valve 3 is closed, the second water outlet 113 stops water output.

[0086] The water inlet assembly 100 has a water distribution function, and can divide the water input from the first water inlet 111 into two paths, one of which is delivered to the brush ring spray head of the toilet bowl as toilet flushing water, and the other of which is delivered to the human body cleaning assembly and the foam generating assembly as human body cleaning water and foam liquid dilution water respectively, so that the toilet flushing water and the human body cleaning water can be effectively separated, and the toilet flushing water can be prevented from polluting the human body cleaning water.

[0087] At the same time, the water output from the second water outlet 113 has been filtered twice by the first filter assembly 4 and the second filter assembly 5, and is more pure, which can ensure the health of the human body when the water is used to flush the human body, and can prevent impurities from entering the foam generating assembly to cause damage when the water is used as foam liquid dilution water.

[0088] In particular, the second filter assembly 5 is arranged downstream of the second valve 3, the water pressure of the water path downstream of the second valve 3 is stable and low, which can ensure that the second filter assembly 5 will not burst due to unstable water pressure. The second valve 3 is arranged downstream of the first filter assembly 4, which can avoid the second valve 3 being blocked by impurities in the water.

[0089] The water inlet assembly 100 has high integration and compact structure, and occupies small space.

[0090] In an illustrative embodiment, as shown in Figure 5 , 7 shown, the first filter assembly 4 includes a filter screen support 41 and a filter screen 42. The filter inlet 4111 and the filter outlet 4112 are arranged on the filter screen support 41. The first filter flow channel 4113 is further arranged on the filter screen support 41. The first filter flow channel 4113 extends from the filter inlet 4111 to the outlet of the filter screen 42. One end of the first filter flow channel 4113 is connected to the first water inlet 111 of the filter support 1 through the filter inlet 4111, and the other end is connected to the water inlet 31 of the second valve 3 through the filter outlet 4112. The filter screen 42 is configured in a mesh structure. The filter screen 42 can be a metal mesh or a nylon mesh. The filter screen 42 is arranged on the filter screen support 41. The surface of the filter screen support 41 is provided with a rubber coating layer, which connects the filter screen 42 to the filter screen support 41, so that the filter screen 42 and the filter screen support 41 are integrally formed. The filter screen 42 is provided with a plurality of mesh holes. The size of the mesh hole can be 100 mesh. The filter screen 42 is arranged on the first filter flow channel 4113.

[0091] The second filter assembly 5 comprises a scale inhibitor bracket 51 and a scale inhibitor 52. The scale inhibitor bracket 51 is provided with a scale inhibitor inlet 512 and a scale inhibitor outlet 513. The scale inhibitor bracket 51 is provided with a scale inhibitor cavity 511. The scale inhibitor cavity 511 is communicated with the water outlet 32 of the second valve 3 through the scale inhibitor inlet 512, and is communicated with the second water outlet 113 of the filter bracket 1 through the scale inhibitor outlet 513. The scale inhibitor inlet 512 and the scale inhibitor outlet 513 are through holes penetrating the wall of the scale inhibitor cavity 511. The scale inhibitor inlet 512 and the scale inhibitor outlet 513 are communicated with the scale inhibitor cavity 511.

[0092] The scale inhibitor 52 is a kind of agent which can disperse the insoluble inorganic salt in water, prevent or interfere the precipitation of insoluble inorganic salt on the surface of metal, and maintain the good heat transfer effect of metal equipment. The scale inhibitor 52 can be configured as solid particles or block porous structure. The scale inhibitor 52 is filled in the scale inhibitor cavity 511 of the scale inhibitor bracket 51.

[0093] In this way, when the second valve 3 is opened, the water flows through the first water inlet 111 of the filter bracket 1, the filter inlet 4111 of the first filter assembly 4, the first filter flow channel 4113, the filter outlet 4112 of the first filter assembly 4, the water inlet 31 of the second valve 3, the water outlet 32 of the second valve 3, the scale inhibitor inlet 512 of the second filter assembly 5, the scale inhibitor cavity 511, the scale inhibitor outlet 513, and the second water outlet 113 of the filter bracket 1 in sequence. The water is filtered by the filter screen 42 when flowing through the first filter flow channel 4113 of the filter screen bracket 41, and the solid impurities larger than the mesh of the filter screen 42 are filtered out. The insoluble inorganic salt and solid impurities in the water are removed by the scale inhibitor when flowing through the scale inhibitor cavity 511, so as to avoid the scaling in the water path of the human body cleaning assembly when the heating device heats the water.

[0094] In an exemplary embodiment, the filter bracket 1 comprises a mounting cylinder 11. The mounting cylinder 11 is configured as a substantially cylindrical shape. The first filter assembly 4 and the second filter assembly 5 are arranged in the mounting cylinder 11 in sequence along the axial direction of the mounting cylinder 11. The mounting cylinder 11 can be vertically arranged, and the first filter assembly 4 is located below the second filter assembly 5. The scale inhibitor bracket 51 is detachably connected to the mounting cylinder 11. The scale inhibitor bracket 51 is connected to the filter screen bracket 41.

[0095] The first water inlet 111 is arranged at the end of the mounting cylinder 11 near the first filter assembly 4. The first water outlet 112 is arranged on the side wall of the mounting cylinder 11 near the first filter assembly 4, and the first water outlet 112 can be located outside the filter bracket 1. The second water outlet 113 is arranged on the side wall of the mounting cylinder 11 near the second filter assembly 5, and the second water outlet 113 is communicated with the scale inhibitor outlet 513 of the scale inhibitor bracket 51.

[0096] The side wall of the mounting cylinder 11 is further provided with a first water outlet hole 114 and a first water inlet hole 115. The first water outlet hole 114 is aligned with the water inlet 31 of the second valve 3. One end of the first water outlet hole 114 is communicated with the first filter flow channel 4113 of the filter support 1, and the other end of the first water outlet hole 114 is communicated with the water inlet 31 of the second valve 3. The first water inlet hole 115 is located outside the scale inhibition support 51. The first water inlet hole 115 can be aligned with the scale inhibition inlet 512 of the scale inhibition support 51 in the axial direction of the mounting cylinder 11. One end of the first water inlet hole 115 is communicated with the water outlet 32 of the second valve 3, and the other end of the first water inlet hole 115 is communicated with the scale inhibition inlet 512 of the scale inhibition support 51.

[0097] The mounting cylinder 11 is sleeved on the scale inhibition support 51, which can further prevent the scale inhibition support 51 from being burst due to water pressure. Since the scale inhibition support 51 is connected to the filter screen support 41 and detachably connected to the mounting cylinder 11, the first filter assembly 4 and the second filter assembly 5 can be simultaneously installed in or detached from the mounting cylinder 11, and the first filter assembly 4 and the second filter assembly 5 are more convenient to disassemble and assemble, and the filter screen 42 of the first filter assembly 4 can be cleaned after being disassembled.

[0098] In this way, when the second valve 3 is opened, the water flows through the first water inlet hole 111 of the mounting cylinder 11, the filter inlet 4111 of the filter support 1, the first filter flow channel 4113, the filter outlet 4112, the first water outlet hole 114 of the mounting cylinder 11, the water inlet 31 of the second valve 3, the water outlet 32 of the second valve 3, the first water inlet hole 111 of the mounting cylinder 11, the scale inhibition inlet 512 of the scale inhibition support 51, the scale inhibition cavity 511, the scale inhibition outlet 513, and the second water outlet 113 of the filter support 1 in sequence.

[0099] In an exemplary embodiment, the second valve 3 is fixed on one side of the mounting cylinder 11. The water inlet 31 of the second valve 3 is directly connected to the first water outlet hole 114 of the mounting cylinder 11, and the water outlet 32 of the second valve 3 is directly connected to the first water inlet hole 115 of the mounting cylinder 11.

[0100] In this way, fixing the second valve 3 on one side of the mounting cylinder 11 can improve the integration level of the water inlet assembly 100, has a higher modularization level, and has a more compact structure and occupies a smaller space.

[0101] In an illustrative embodiment, the scale-inhibiting bracket 51 is configured as a cylinder. The scale-inhibiting bracket 51 can have a circular cross-section and be coaxial with the mounting cylinder 11. An end of the scale-inhibiting bracket 51 opposite the filter screen bracket 41 is closed. An end of the scale-inhibiting bracket 51 toward the filter screen bracket 41 is provided with a charging port 518. The charging port 518 can be a circular opening. The charging port 518 is connected to a scale-inhibiting cavity 511 of the scale-inhibiting bracket 51.

[0102] The filter screen bracket 41 is detachably connected to the scale-inhibiting bracket 51. The filter screen bracket 41 can be detachably snap-connected, screw-connected or thread-connected to the scale-inhibiting bracket 51. The filter screen bracket 41 blocks the charging port 518 of the scale-inhibiting bracket 51.

[0103] In this way, when the scale-inhibiting agent 52 in the scale-inhibiting bracket 51 needs to be replaced, the user can first detach the first filter assembly 4 and the second filter assembly 5 from the mounting cylinder 11, then detach the filter screen bracket 41 from the scale-inhibiting bracket 51 to open the charging port 518 of the scale-inhibiting bracket 51, then replace the scale-inhibiting agent 52 in the scale-inhibiting cavity 511 through the charging port 518, then reattach the filter screen bracket 41 to the scale-inhibiting bracket 51, and finally reattach the first filter assembly 4 and the second filter assembly 5 to the mounting cylinder 11. In this way, the user can conveniently replace the scale-inhibiting agent 52 by himself, and the user experience is better.

[0104] In an illustrative embodiment, the scale-inhibiting bracket 51 is provided with a first annular groove 514 and a second annular groove 515. The first annular groove 514 and the second annular groove 515 can each be a circular ring and surround the scale-inhibiting bracket 51. The first annular groove 514 can be disposed below the second annular groove 515. The first annular groove 514 and the second annular groove 515 are spaced apart and not connected to each other. The scale-inhibiting inlet 512 is disposed at the bottom of the first annular groove 514. The scale-inhibiting outlet 513 is disposed at the bottom of the second annular groove 515.

[0105] The mounting cylinder 11 is sleeved on the scale-inhibiting bracket 51, and the inner peripheral wall of the mounting cylinder 11 covers the openings of the first annular groove 514 and the second annular groove 515 of the scale-inhibiting bracket 51. The first water inlet hole 115 of the mounting cylinder 11 is flush with the first annular groove 514 in the axial direction of the mounting cylinder 11, and an inward end of the first water inlet hole 115 of the mounting cylinder 11 is connected to the first annular groove 514. The second water outlet 113 of the mounting cylinder 11 is flush with the second annular groove 515 in the axial direction of the mounting cylinder 11, and the second water outlet 113 of the mounting cylinder 11 is connected to the second annular groove 515.

[0106] In this way, the first water inlet hole 115 on the mounting cylinder 11 can be communicated with the scale inhibition inlet 512 of the scale inhibition support 51 through the first annular groove 514, and the second water outlet hole 113 on the mounting cylinder 11 can be communicated with the scale inhibition outlet 513 of the scale inhibition support 51 through the second annular groove 515, so that the first water inlet hole 115 does not need to be accurately aligned with the scale inhibition inlet 512, and the second water outlet hole 113 does not need to be accurately aligned with the scale inhibition outlet 513, thereby reducing the matching precision requirement between the mounting cylinder 11 and the scale inhibition support 51, and facilitating production and installation.

[0107] In an exemplary embodiment, as shown in Figure 7 , the inner circumferential wall of the mounting cylinder 11 is provided with an internal thread 116. The outer circumferential wall of the scale inhibition support 51 is provided with an external thread 517 that is screwed with the internal thread 116. The external thread 517 of the scale inhibition support 51 can be provided at the end of the scale inhibition support 51 close to the filter support 41.

[0108] The scale inhibition support 51 and the mounting cylinder 11 are threadedly connected through the cooperation of the internal thread 116 and the external thread 517, and the scale inhibition support 51 can be disassembled only by rotating relative to the mounting cylinder 11, so that the scale inhibition support 51 is more convenient to disassemble.

[0109] In an exemplary embodiment, as shown in Figure 5 , the end of the scale inhibition support 51 away from the filter support 1 is provided with a handle 516 that extends out of the mounting cylinder 11. The handle 516 can be configured as a plate structure.

[0110] The user can operate the handle 516 to rotate the scale inhibition support 51, which is more convenient for disassembling the scale inhibition support 51.

[0111] In an exemplary embodiment, as shown in Figure 5 , 7 The filter support 41 is configured as a cylinder with both ends closed. The filter inlet 4111 and the filter outlet 4112 are both provided on the side wall of the filter support 41. The filter inlet 4111 is provided in multiple, preferably two. The multiple filter outlets 4112 are located at the end of the filter support 41 close to the first water inlet hole 111. The multiple filter outlets 4112 can be uniformly distributed around the circumference of the filter support 1. The filter outlet 4112 is provided on the side of the filter outlet 4112 away from the first water inlet hole 111. The filter outlet 4112 is communicated with the first water outlet hole 114 of the filter support 1. The first filter flow channel 4113 is an internal passage of the filter support 41, and the first filter flow channel 4113 extends from each filter inlet 4111 to the filter outlet 4112.

[0112] The filter screen 42 is configured in a cylindrical shape, and is arranged in the first filtering flow channel 4113 of the filter screen support 41. The filter screen 42 covers all the filtering inlets 4111 of the filter screen support 41.

[0113] In this way, the filter screen 42 is embedded in the filter screen support 41, and the filter screen 42 is not easy to come out of the filter screen support 41. Meanwhile, the filter screen support 41 is provided with a plurality of filtering inlets 4111, and the cylindrical filter screen 42 covers all the filtering inlets 4111, so that the filter screen 42 can be as large as possible in the limited space, and the resistance of the filter screen 42 to water flow is reduced.

[0114] In an exemplary embodiment, as shown in Figure 5 , 7 the filter screen support 41 comprises a support body 411 and a plug 412. The support body 411 is configured in a cylindrical structure with one end closed. A plurality of filtering outlets 4112 are arranged on the side wall of the support body 411, and the first filtering flow channel 4113 is arranged in the support body 411. The plug 412 is plugged into the end of the support body 411 which is not closed.

[0115] In an exemplary embodiment, the water inlet assembly 100 further comprises a third valve 7. The third valve 7 is arranged at the first water inlet 111, and the filter screen support 41 is arranged between the third valve 7 and the scale inhibitor, and the filter screen support 41 presses the third valve 7. The third valve 7 is configured to open the first water inlet 111 when pressed by the filter screen support 41, and to close the first water inlet 111 when not pressed by the filter screen support 41.

[0116] When the first filtering assembly 4 and the second filtering assembly 5 are both installed in the mounting cylinder 11, the third valve 7 is opened, and water can be input from the first water inlet 111 into the mounting cylinder 11. When the first filtering assembly 4 and the second filtering assembly 5 are removed from the mounting cylinder 11, the filter screen support 41 no longer presses the third valve 7, and the third valve 7 is closed, so that water cannot be input from the first water inlet 111 into the mounting cylinder 11.

[0117] In this way, the user can remove the first filtering assembly 4 and the second filtering assembly 5 from the mounting cylinder 11 without closing the water source. After the first filtering assembly 4 and the second filtering assembly 5 are removed, the third valve 7 closes the first water inlet 111, and water cannot flow out of the mounting cylinder 11. After the first filtering assembly 4 and the second filtering assembly 5 are reinstalled in the mounting cylinder 11, the third valve 7 is pressed by the filter screen support 41 and is reopened, and the first water inlet 111 can input water again. In this way, the user can replace the scale inhibitor 52 more conveniently.

[0118] In an exemplary embodiment, as shown in Figure 4 , 8As shown, the third valve 7 comprises a seat body 71, a sealing gasket 77, a closing member 75 and a resilient member 74. The seat body 71 comprises a valve seat 711, a connecting seat 712 and a connecting portion 713. The valve seat 711 is configured as a cylinder. The valve seat 711 is arranged in the mounting cylinder 11, and the outer peripheral wall of the valve seat 711 abuts against the inner peripheral wall of the mounting cylinder 11. The valve seat 711 is provided with an internal passage.

[0119] The connecting seat 712 is located on the side of the valve seat 711 away from the filter screen support 41. The connecting seat 712 can be configured as a ring. The connecting seat 712 can be coaxially arranged with the seat body 71. The connecting seat 712 is provided with a sliding channel, which is a straight strip and coaxial with the valve seat 711, and the sliding channel penetrates through the connecting seat 712.

[0120] The connecting portion 713 can be configured as a strip. The connecting portion 713 extends from the valve seat 711 to the connecting seat 712. The connecting portion 713 connects the connecting seat 712 and the valve seat 711. The connecting portion 713 can be provided with multiple, and the multiple connecting portions 713 are uniformly distributed in the circumferential direction of the connecting seat 712.

[0121] The sealing gasket 77 is flexible. The sealing gasket 77 can be a rubber ring. The sealing gasket 77 is fixed on the valve seat 711. The sealing gasket 77 is arranged at one end of the valve seat 711 close to the connecting portion 713. The sealing gasket 77 is coaxially arranged with the valve seat 711. The internal passage of the sealing gasket 77 is communicated with the internal passage of the valve seat 711.

[0122] The closing member 75 comprises a valve rod 751 and a valve flap 752. The valve rod 751 is configured as a straight rod. One end of the valve rod 751 is inserted into the sliding channel of the connecting portion 713. The valve rod 751 and the sliding channel are gap-fitted. The valve rod 751 can slide along the sliding channel.

[0123] The valve flap 752 can be configured as a disc. The valve flap 752 is arranged between the sealing gasket 77 and the connecting seat 712. The valve flap 752 is connected to one end of the valve rod 751 close to the valve seat 711. The valve flap 752 can be coaxially arranged with the sealing gasket 77. The diameter of the valve flap 752 is greater than the diameter of the internal passage of the sealing gasket 77. The valve flap 752 can block one end of the internal passage of the sealing gasket 77 towards the valve flap 752.

[0124] The resilient member 74 can be a compression spring. One end of the resilient member 74 abuts against one end of the valve flap 752 towards the connecting seat 712, and the other end of the resilient member 74 abuts against one end of the connecting seat 712 towards the valve flap 752. The resilient member 74 is in a compressed state. The resilient member 74 applies a spring force to the valve flap 752 towards the sealing gasket 77.

[0125] When the first filter assembly 4 and the second filter assembly 5 are installed in the cylinder, the end of the filter screen support 41 away from the descaling support presses the valve flap 752 to separate the valve flap 752 and the sealing gasket 77.

[0126] Thus, when the first filter assembly 4 and the second filter assembly 5 are installed in the cylinder, the filter screen support 41 compresses the valve disc 752, causing the valve disc 752 of the third valve 7 and the sealing gasket 77 to separate. The third valve 7 is opened, and water enters the installation cylinder 11 from the first inlet 111. It then flows sequentially through the gap between the valve seat 711 and the valve disc 752, the internal channel of the gasket, and the internal channel of the valve seat 711 to reach the first outlet 112 and the filter inlet 4111 of the filter screen support 41. After the first filter assembly 4 and the second filter assembly 5 are removed from the cylinder, the valve disc 752 moves to abut against the gasket under the elastic force of the elastic member 74, blocking the internal channel of the gasket. The third valve 7 is closed, and water cannot reach the first outlet 112 and the filter inlet 4111 of the filter screen support 41 through the internal channel of the gasket.

[0127] In one illustrative embodiment, such as Figure 3 As shown, the water inlet assembly 100 also includes a battery 84. The battery 84 may be rectangular in shape. The battery 84 is electrically connected to and supplies power to the electrical devices of the toilet. In the event of a power outage, the battery 84 can supply power to the first valve 2 and some of the electrical devices in the flushing system.

[0128] like Figure 2 , 3 As shown, the filter support 1 also includes a battery compartment 12 and a foam liquid compartment 13. The water inlet assembly 100 also includes a battery cover 81 and a filling cover 82. The battery compartment 12 is used to house the battery 84 and protect it from water and dust contamination. The foam liquid compartment 13 is used to add foam liquid. The foam liquid compartment 13 is provided with a foam liquid outlet, which is connected to the foam generating assembly of the toilet via a pipe. Both the battery compartment 12 and the foam liquid compartment 13 are located on the side of the mounting cylinder 11 facing away from the water inlet. The battery compartment 12, the foam liquid compartment 13, and the mounting cylinder 11 can be an integrally formed structure. The tops of the battery compartment 12 and the foam liquid compartment 13 can be provided with openings. The battery cover 81 can be closed over the opening of the battery compartment 12 to seal the opening. The filling cover 82 can be closed over the opening of the foam liquid compartment 13 to seal the opening.

[0129] In this way, the battery 84 and the foam liquid are respectively housed in the battery compartment 12 and the foam liquid compartment 13, and the battery compartment 12 and the foam liquid compartment 13 are located at the top of the mounting cylinder 11, which not only facilitates the replacement of the battery 84 and the addition of foam liquid, but also makes the overall structure of the water inlet assembly 100 compact and occupies a small volume.

[0130] In one illustrative embodiment, the second valve 3 includes a valve body 30. The valve body 30 is provided with an inlet 31, an outlet 32, and a water passage 33 extending from the inlet 31 to the outlet 32.

[0131] like Figure 10As shown, the second valve 3 further comprises a flow restrictor 34 and a water inlet check valve 35. The flow restrictor 34 and the water inlet check valve 35 are arranged in sequence on the water flow passage 33. The water inlet check valve 35 can be arranged downstream of the flow restrictor 34. The water inlet check valve 35 is configured to only allow water flow from the water inlet 31 of the valve body 30 to the water outlet 32 of the valve body 30. The water inlet check valve 35 prevents water flow in the reverse direction. The flow restrictor 34 is configured to adjust the flow rate of water flowing through the water flow passage 33. The flow restrictor 34 limits the flow rate of water flowing through the second valve 3, which further prevents the water pressure of the water flowing into the second filter assembly 5 from being too high to cause the second filter assembly 5 to burst open.

[0132] In an exemplary embodiment, as shown in Figure 11 、 12 , the filter support 1 further comprises a water outlet connector 117. The water outlet connector 117 is arranged on the outer side wall of the mounting cylinder 11. The water outlet connector 117 is connected to the first water outlet 112 of the mounting cylinder 11.

[0133] As shown in Figure 11 , the water inlet assembly 100 further comprises a flushing adapter 9. The flushing adapter 9 comprises a water inlet connector 91, an elbow 92 and a clamping seat 93. The water inlet connector 91 is inserted into the water outlet connector 117 of the filter support 1. The elbow 92 can be configured as a straight elbow 92. One end of the elbow 92 is connected to the water inlet connector 91, and the other end of the elbow 92 extends upward. The clamping seat 93 is connected to the end of the elbow 92 facing away from the water inlet connector 91. One end of the first valve 2 provided with the water inlet is clamped to the clamping seat 93. The water outlet 22 of the first valve 2 is used to connect a brush ring spray head.

[0134] In this way, the first valve 2 is adapted to the mounting cylinder 11 through the water outlet connector 117, and the water outlet connector 117 connects the water inlet 21 of the first valve 2 and the first water outlet 112 of the mounting cylinder 11, so that the position of the first valve 2 can be arranged more flexibly.

[0135] In an exemplary embodiment, the clamping seat 93 is configured as an annular shape. The clamping seat 93 is provided with a clamping groove 931 on the inner wall thereof. The clamping groove 931 extends along the circumference of the clamping seat 93. One end of the clamping groove 931 is provided with a disassembly opening 932.

[0136] The outer peripheral wall of one end of the first valve 2 provided with the water inlet is provided with a protrusion 23. The protrusion 23 can be a strip shape, and the protrusion 23 extends along the circumference of the outer peripheral wall of the first valve 2. The protrusion 23 is accommodated in the clamping groove 931 of the clamping seat 93. The length of the protrusion 23 is less than the width of the disassembly opening 932 of the clamping seat 93, so that the protrusion 23 can pass through the disassembly opening 932.

[0137] In this way, when the first valve 2 needs to be installed on the clamping seat 93, the first valve 2 is inserted into the clamping seat 93 so that the protruding portion 23 is aligned with the dismounting opening 932, and then the first valve 2 is rotated so that the protruding portion 23 slides along the clamping groove 931 and enters the clamping groove 931, thereby achieving the clamping connection of the first valve 2 and the clamping seat 93. When the first valve 2 needs to be dismounted from the clamping seat 93, the first valve 2 is only needed to be rotated so that the protruding portion 23 moves out of the clamping groove 931 from the dismounting opening 932, and then the first valve 2 is pulled out of the clamping seat 93.

[0138] In an exemplary embodiment, as shown in Figure 3 The water inlet assembly 100 further comprises a radio frequency module 6. The radio frequency module 6 is used for wireless communication with a remote controller. The radio frequency module 6 is connected to the flushing adapter 9. The radio frequency module 6 can be arranged on one side of the clamping seat 93 and clamped to the clamping seat 93.

[0139] The radio frequency module 6 is connected to the flushing adapter 9, and the space on one side of the flushing adapter 9 can be fully utilized, so that the overall structure of the water inlet assembly 100 is more compact and occupies a smaller volume.

[0140] In an exemplary embodiment, as shown in Figure 1 , 4 The water inlet assembly 100 further comprises a water delivery pipe 83, both ends of the water delivery pipe 83 being connected to the water outlet 32 of the second valve 3 and the first water inlet hole 115 of the mounting cylinder 11 respectively. The water outlet 32 of the second valve 3 and the first water inlet hole 115 of the mounting cylinder 11 are connected in communication through the water delivery pipe 83.

[0141] The present embodiment further provides a toilet, which comprises the above water inlet assembly 100, the above human body cleaning assembly, the above brush circle spray head, the above foam generating assembly and a ceramic toilet bowl.

The brush circle spray head is arranged at the top of the toilet cavity. The brush circle spray head is connected to the water outlet 22 of the first valve 2 in communication through a pipeline. The brush circle spray head can spray the water output by the first valve 2 into the toilet cavity to flush the toilet cavity. The human body cleaning assembly and the foam generating assembly are connected to the second water outlet 113 of the water inlet assembly 100. The human body cleaning assembly is arranged on one side of the toilet cavity. The human body cleaning assembly is provided with a spray head for spraying water upward. A heating device or instant heating assembly can heat the water output by the second water outlet 113 and spray the heated water from the spray head. The foam outlet of the foam generating assembly is connected to the toilet cavity. The foam generating assembly mixes the water, foam liquid and air provided by the water inlet assembly 100 into foam and outputs the foam into the toilet cavity from the foam outlet.
