Description

Technical Field

[0001] This application relates to bathroom technology, especially an inlet assembly and a filtration module of a toilet. Background Art

[0002] Intelligent toilets are becoming more and more popular in modern life. Currently, most intelligent toilets on the market need to use a filtration device to filter water when connecting to municipal water. However, since the positions of the water inlet and the water outlet of the filtration device are both fixed, the adaptability of filtration devices of the same model is not wide. Summary of the Invention

[0003] The technical problem to be solved by this application is how to improve the application range of the filtration module.

[0004] To solve the above technical problem, this application proposes a filtration module, which includes: a first filtration component and a second filtration component;

[0005] The first filtration component includes:

[0006] A filtration bracket, provided with a filtration inlet, a filtration outlet, and a filtration flow channel extending from the filtration inlet to the filtration outlet; and,

[0007] A filtration medium, arranged on the filtration flow channel;

[0008] The second filtration component includes:

[0009] A scale inhibitor bracket, connected to the filtration bracket, provided with a scale inhibitor cavity, and a first opening and a second opening both communicating with the scale inhibitor cavity; and

[0010] A scale inhibitor, filled in the scale inhibitor cavity;

[0011] The distances from the first opening and the second opening to the filtration outlet are different, and the filtration outlet is configured to be able to connect to the first opening or the second opening.

[0012] In this way, water is input into the filtration flow channel of the filtration bracket from the filtration inlet. When the water flows through the filtration flow channel, solid particle impurities in the water will be filtered out. The filtered water is then transported to the scale inhibitor cavity through the filtration outlet. When the water flows through the scale inhibitor cavity, it can chelate metal cations in the water with the scale inhibitor, preventing scale formation.

[0013] Meanwhile, the filtration outlet can be connected to the first opening, and the water flow output from the filtration outlet flows into the scale inhibition cavity through the first opening and then flows out of the descaling cavity through the second opening; alternatively, the filtration outlet can be connected to the second opening, and the water flow output from the filtration outlet flows into the scale inhibition cavity through the second opening and then flows out of the descaling cavity through the first opening. This is equivalent to being able to select one of the first opening and the second opening as the water outlet of the filtration module. Therefore, the filtration outlet can be connected to one of the first opening and the second opening as needed, making the waterway connection method more diverse, with a wider application range and stronger versatility.

[0014] Other features and advantages of the present application will be described in the subsequent specification. Moreover, some will become apparent from the specification or be understood by implementing the present application. Other advantages of the present application can be realized and obtained through the solutions described in the specification and the drawings. Brief Description of the Drawings

[0043] As Figures 1 - 4 shown, Figures 1 - 4 A filtering module 1a in an embodiment of this application is shown. The filtering module 1a includes a first filtering component 4 and a second filtering component 5. The first filtering component 4 is connected to the second filtering component 5.

[0044] The first filtering component 4 includes a filtering bracket 41 and a filtering medium 42. The filtering bracket 41 is provided with a filtering inlet 4111, a filtering outlet 4112, and a filtering flow channel. The filtering flow channel is arranged inside the filtering bracket 41 and extends from the filtering inlet 4111 to the filtering outlet 4112. The shape of the filtering flow channel is not limited, and the filtering flow channel can be a straight channel or a curved channel.

[0045] As Figure 6 shown, the filtering medium 42 is fixed on the filtering bracket 41, and the filtering medium 42 is arranged inside the filtering flow channel 4113. The filtering medium 42 is used to filter solid particle impurities in water. The filtering medium 42 can be a filter screen, the filter screen is provided with a plurality of mesh holes, the size of the mesh holes can be 100 meshes, and the filter screen is, for example, a nylon mesh or a metal mesh. The filtering medium 42 can also be a granular medium, a porous medium, activated carbon, diatomaceous earth, gauze, canvas, filter paper, filter membrane, polypropylene fiber, polyester fiber, polytetrafluoroethylene, or glass fiber. When the water flow in the filtering flow channel passes through the filtering medium 42, the solid particle impurities in the water will be filtered out.

[0046] The second filtration component 5 includes a scale inhibitor support 51 and a scale inhibitor 52. The scale inhibitor support 51 is connected to the filtration support 41. A first opening 512 and a second opening 513 are provided on the scale inhibitor support 51. A scale inhibitor cavity 511 is provided inside the scale inhibitor support 51. The scale inhibitor cavity 511 can be set as a cylindrical cavity. Both the first opening 512 and the second opening 513 are through holes penetrating the wall surface of the scale inhibitor cavity 511. Both the first opening 512 and the second opening 513 communicate with the scale inhibitor cavity 511.

[0047] The scale inhibitor 52 is filled in the scale inhibitor cavity 511, and the scale inhibitor 52 can be filled. The scale inhibitor 52 has the functions of dispersing insoluble inorganic salts in water, preventing or interfering with the precipitation and scaling of insoluble inorganic salts on the metal surfaces in the subsequent water passages and the cavities of each component. The scale inhibitor 52 can be constructed as solid particles or as a porous structure in a block shape. The scale inhibitor 52 is filled in the scale inhibitor cavity 511 of the scale inhibitor support 51. When water flows through the scale inhibitor cavity 511, the scale inhibitor 52 can chelate metal cations in the water.

[0048] The distances from the first opening 512 and the second opening 513 on the scale inhibitor support 51 to the filtration outlet 4112 on the filtration support 41 are different. The filtration outlet 4112 on the filtration support 41 is used to connect to the first opening 512 or the second opening 513, and the filtration outlet 4112 can be connected to the first opening 512 or the second opening 513 through a water passage or a valve.

[0049] In this way, water is input from the filtration inlet 4111 into the filtration flow channel of the filtration support 41. When the water flows through the filtration flow channel, solid particle impurities in the water will be filtered out. The filtered water is then transported to the descaling cavity through the filtration outlet 4112. When the water flows through the descaling cavity, it can chelate metal cations in the water with the scale inhibitor 52, preventing the generation of water scale.

[0050] At the same time, as Figure 8 shown, the filtration outlet 4112 can be connected to the first opening 512. The water flow output from the filtration outlet 4112 flows into the scale inhibitor cavity 511 from the first opening 512 and then flows out of the descaling cavity from the second opening 513; as Figure 9 shown, the filtration outlet 4112 can also be connected to the second opening 513. The water flow output from the filtration outlet 4112 flows into the scale inhibitor cavity 511 from the second opening 513 and then flows out of the descaling cavity from the first opening 512. It is equivalent to being able to select one of the first opening 512 and the second opening 513 at different positions as the water outlet of the filtration module 1a. Therefore, the filtration outlet 4112 can be connected to one of the first opening 512 and the second opening 513 as needed, and the waterway connection method is more diverse, with a wider application range and stronger versatility.

[0051] In a schematic embodiment, the filtering bracket 41 is disposed below the scale inhibitor bracket 51, and the first opening 512 of the scale inhibitor bracket 51 is disposed below the second opening 513 of the scale inhibitor bracket 51.

[0052] In this way, the filtering outlet 4112 on the filtering bracket 41 can communicate with the first opening 512, such that the lower-positioned first opening 512 admits water and the higher-positioned second opening 513 discharges water; the filtering outlet 4112 on the filtering bracket 41 can communicate with the second opening 513, such that the higher-positioned second opening 513 admits water and the lower-positioned first opening 512 discharges water.

[0053] In a schematic embodiment, a charging port 518 is provided at one end of the scale inhibitor bracket 51 facing the filtering bracket 41. The charging port 518 may be a circular opening. The charging port 518 communicates with the scale inhibitor cavity 511 of the scale inhibitor bracket 51.

[0054] The filtering bracket 41 is detachably connected to the scale inhibitor bracket 51. The filtering bracket 41 and the scale inhibitor bracket 51 may be detachably connected by snap connection, screw connection or bolt connection. The filtering bracket 41 seals the charging port 518 of the scale inhibitor bracket 51.

[0055] When the user needs to replace the scale inhibitor 52 in the scale inhibitor bracket 51, the user can detach the filtering bracket 41 from the scale inhibitor bracket 51 to open the charging port 518 on the scale inhibitor bracket 51, then replace the scale inhibitor 52 in the scale inhibitor cavity 511 through the charging port 518, and then reinstall the filtering bracket 41 onto the scale inhibitor bracket 51. Thus, the user can conveniently replace the scale inhibitor 52 by himself / herself, and the user experience is better.

[0056] In a schematic embodiment, a detachable snap connection is adopted between the filtering bracket 41 and the scale inhibitor bracket 51. A plurality of first snaps 414 are provided on the filtering bracket 41. A plurality of first snap holes 519 are provided at one end of the scale inhibitor bracket 51 close to the filtering bracket 41. The first snap holes 519 are configured as through holes penetrating the side wall of the scale inhibitor bracket 51. The number of the first snaps 414 and the first snap holes 519 may both be 2. The plurality of first snaps 414 hook the plurality of first snap holes 519, thereby connecting the filtering bracket 41 and the scale inhibitor together.

[0057] In this way, during assembly, only the filtering bracket 41 and the scale inhibitor bracket 51 need to be docked, such that the plurality of first snaps 414 hook the plurality of first snap holes 519, thereby assembling the filtering bracket 41 and the scale inhibitor bracket 51 together, and the assembly speed is improved. During disassembly, only the first snaps 414 need to be pushed out from the first snap holes 519 to disassemble the filtering bracket 41 and the scale inhibitor bracket 51.

[0058] In a schematic embodiment, as Figure 3, 5 As shown in 5 , one end of the scale inhibitor bracket 51 facing the filter bracket 41 is further provided with a limiting groove 520, and the limiting groove 520 is located on one side of the charging port 518. The opening of the limiting groove 520 faces the filter bracket 41. A limiting protrusion 413 is provided on the side wall of the filter bracket 41, and the limiting protrusion 413 protrudes radially outward from the surface of the filter bracket 41. The limiting protrusion 413 of the filter bracket 41 is received in the limiting groove 520 of the scale inhibitor bracket 51. The limiting groove 520 and the limiting protrusion 413 may both be provided with two. The two limiting grooves 520 are respectively located on opposite sides of the charging port 518, and the two limiting protrusions 413 are respectively arranged corresponding to the two limiting grooves 520, and the two limiting protrusions 413 are respectively received in the two limiting grooves 520.

[0059] Since the limiting protrusion 413 of the filter bracket 41 is received in the limiting groove 520 of the scale inhibitor bracket 51, the scale inhibitor bracket 51 and the limiting protrusion 413 cannot rotate relative to each other, so that the snap connection between the scale inhibitor bracket 51 and the limiting protrusion 413 can be effectively prevented from being damaged.

[0060] In a schematic embodiment, both the scale inhibitor bracket 51 and the filter bracket 41 are configured as cylindrical. The scale inhibitor bracket 51 and the filter bracket 41 are coaxially arranged. One end of the scale inhibitor bracket 51 and the filter bracket 41 close to each other are connected to each other.

[0061] The scale inhibitor cavity 511 is configured as a generally columnar cavity and is coaxial with the scale inhibitor bracket 51. The charging port 518 and the limiting groove 520 are both provided at one end of the scale inhibitor bracket 51 facing the filter bracket 41, and one end of the scale inhibitor bracket 51 facing away from the filter bracket 41 is closed. The first opening 512 and the second opening 513 are both provided on the side wall of the scale inhibitor bracket 51 and both penetrate the side wall of the scale inhibitor bracket 51. The positions of the first opening 512 and the second opening 513 are different in the axial direction of the scale inhibitor bracket 51.

[0062] Both ends of the filter bracket 41 are closed. One end of the filter bracket 41 is inserted into the charging port 518 to block the charging port 518. The first snap 414 and the limiting protrusion 413 are both provided on the outer side wall of the filter bracket 41 inserted into the charging port 518. The filter inlet 4111 and the filter outlet 4112 are both provided on the side wall of the filter bracket 41.

[0063] In this way, both the scale inhibitor bracket 51 and the filter bracket 41 are configured as cylindrical, and the scale inhibitor bracket 51 and the filter bracket 41 are coaxially arranged, so that the overall filter module 1a is in a straight bar shape, with a compact structure, small occupied space, and is convenient to be inserted into a straight bar-shaped chamber.

[0064] In a schematic embodiment, as Figure 3 , 6As shown, a plurality of filter inlets 4111 are provided on the filter support 41. A plurality of filter inlets 4111 are provided, preferably two. A plurality of filter outlets 4112 are all located at one end of the filter support 41 facing away from the scale inhibitor support 51. The plurality of filter outlets 4112 may be evenly distributed circumferentially around the filter support 41. The filter outlets 4112 are provided on the side of the plurality of filter inlets 4111 close to the scale inhibitor support 51. The filter flow path extends from each of the filter inlets 4111 to the filter outlets 4112;

[0065] The filter medium 42 is configured as a cylindrical filter screen. The filter medium is disposed in the filter flow path and is coaxially disposed with the filter support 41. The filter medium 42 covers all the filter inlets 4111 on the filter support 41.

[0066] In this way, the filter medium 42 is embedded in the filter support 41, and the filter medium 42 is not easily detached from the filter support 41. At the same time, a plurality of filter inlets 4111 are provided on the filter support 41, and the cylindrical filter medium 42 covers all the filter inlets 4111, which can make the filter medium 42 as large as possible in a limited space and reduce the resistance of the filter medium 42 to the water flow.

[0067] In a schematic embodiment, as Figure 4 、 6 shown, the filter support 41 includes a support body 411 and a plug 412. The support body 411 is configured as a cylindrical structure with one end closed. The support body 411 is coaxially disposed with the scale inhibitor support 51. The closed end of the support body 411 is inserted into the charging port 518 of the scale inhibitor support 51. A plurality of filter inlets 4111, filter outlets 4112, limit protrusions 413 and first buckles 414 are all provided on the side wall of the support body 411. The filter flow path is provided in the support body 411. The plug 412 plugs one end of the support body 411 facing away from the scale inhibitor support 51. The plug 412 and the support body 411 may be snap-connected.

[0068] In a schematic embodiment, the filter medium 42 and the filter support 41 are of an integrally formed structure. The surface of the filter support 41 is provided with a rubber coating layer, and the rubber coating layer connects the filter medium 42 to the filter support 41, so that the filter medium 42 and the filter support 41 are integrally formed.

[0069] The integrally formed structure of the filter medium 42 and the filter support 41 can reduce the number of parts and reduce the assembly steps.

[0070] As Figures 11 - 15 shown, this embodiment also proposes a water inlet assembly 100 of a toilet, and the water inlet assembly 100 includes the above-mentioned filter module 1a and a water inlet valve 3. As Figure 16 、 18As shown, the water inlet 31 of the water inlet valve 3 is communicated with the filtration outlet 4112 of the filtration support 41, and the water outlet 32 of the water inlet valve 3 is communicated with the first opening 512 or the second opening 513.

[0071] In this way, the filtration outlet 4112 on the filtration support 41 is connected to the first opening 512 or the second opening 513 on the scale inhibitor support 51 through the water inlet valve 3. When the water inlet valve 3 is closed, the water path between the filtration flow channel on the filtration support 41 and the scale inhibitor cavity 511 on the scale inhibitor support 51 is cut off, and the second filtration assembly 5 cannot discharge water out through the second opening 513 or the first opening 512. When the water inlet valve 3 is opened, the water path between the filtration flow channel on the filtration support 41 and the scale inhibitor cavity 511 on the scale inhibitor support 51 is connected, and the second filtration assembly 5 can discharge water out through the second opening 513 or the first opening 512.

[0072] The second filtration assembly 5 is arranged downstream of the water inlet valve 3. The water pressure in the water path downstream of the water inlet valve 3 is stable and relatively low, which can ensure that the second filtration assembly 5 will not burst due to unstable water pressure. The water inlet valve 3 is located downstream of the first filtration assembly 4, which can prevent the water inlet valve 3 from being blocked by impurities in the water.

[0073] In a schematic embodiment, the water inlet assembly 100 further includes a mounting bracket 1. The mounting bracket 1 includes a mounting cylinder 11. The mounting cylinder 11 is configured as a substantially cylindrical shape. Both the first filtration assembly 4 and the second filtration assembly 5 are arranged inside the mounting cylinder 11. The first filtration assembly 4 and the second filtration assembly 5 are arranged in sequence along the axial direction of the mounting cylinder 11. The mounting cylinder 11 can be arranged vertically, and the first filtration assembly 4 is located below the second filtration assembly 5. The scale inhibitor support 51 is detachably connected to the mounting cylinder 11. The scale inhibitor support 51 is connected to the filtration support 41.

[0074] The mounting cylinder 11 is sleeved on the scale inhibitor support 51, which can prevent the scale inhibitor support 51 from bursting under the action of water pressure. Since the scale inhibitor support 51 is connected to the filtration support 41 and the scale inhibitor support 51 is detachably connected to the mounting cylinder 11, the first filtration assembly 4 and the second filtration assembly 5 can be inserted into the mounting cylinder 11 as a whole at the same time, or can be detached from the mounting cylinder 11 at the same time. The disassembly and assembly of the first filtration assembly 4 and the second filtration assembly 5 are more convenient, which is convenient for cleaning the impurities on the filtration medium 42 and replacing the scale inhibitor.

[0075] In a schematic embodiment, the water inlet valve 3 is arranged outside the mounting cylinder 11 and fixed on one side of the mounting cylinder 11. The mounting cylinder 11 is provided with a first water inlet 111, a first water outlet hole 114, a first water inlet hole 115 and a first water outlet 113. The first water inlet 111 is arranged at the end of the mounting cylinder 11 close to the first filtration assembly 4. The first water outlet hole 114, the first water inlet hole 115 and the first water outlet 113 are all arranged on the side wall of the mounting cylinder 11.

[0076] The first water inlet 111 is used to connect to the tap water supply pipe externally. The first water inlet 111 on the installation cylinder 11 is connected to the filtration inlet 4111 on the filtration bracket 41. Both ends of the first water outlet hole 114 on the installation cylinder 11 are respectively connected to the water inlet 31 of the water inlet valve 3 and the filtration outlet 4112 of the filtration bracket 41. The water inlet 31 of the water inlet valve 3 is connected to the filtration outlet 4112 through the first water outlet hole 114. Both ends of the first water inlet hole 115 on the installation cylinder 11 are respectively connected to the water outlet 32 of the water inlet valve 3 and the first opening 512 or the second opening 513 on the scale removal bracket. In this way, the water outlet 32 of the water inlet valve 3 is connected to one of the first opening 512 and the second opening 513 through the first water inlet hole 115. The first water outlet 113 on the installation cylinder 11 is connected to the other of the first opening 512 and the second opening 513.

[0077] In this way, the water inlet valve 3 is arranged outside the installation cylinder 11 and fixed on one side of the installation cylinder 11, which can make the whole water inlet assembly 100 more compact. When the water inlet valve 3 is opened, water can flow through the first water inlet 111 of the installation bracket 1, the filtration inlet 4111 of the first filtration assembly 4, the filtration flow channel 4113, the filtration outlet 4112, the water inlet 31 of the water inlet valve 3, the water outlet 32 of the water inlet valve 3, one of the first opening 512 and the second opening 513 of the second filtration assembly 5, the scale inhibition cavity 511, the other of the first opening 512 and the second opening 513, and the first water outlet 113 of the installation bracket 1 in sequence, and is output from the first water outlet 113 of the installation bracket 1. When the water inlet valve 3 is closed, the first water outlet 113 stops discharging water.

[0078] The first water outlet 113 can be used to connect to the body cleaning assembly and the foam generating assembly. The first water outlet 113 conveys the purified water to the body cleaning assembly and the foam generating assembly respectively as the body cleaning water and the foam liquid dilution water. At the same time, the water output from the first water outlet 113 has been purified twice by the first filtration assembly 4 and the second filtration assembly 5, and the water is purer. When used as the body cleaning water to wash the body, it can ensure the health of the human body. When used as the foam liquid dilution water, it can prevent damage caused by impurities entering the foam generating assembly.

[0079] In a schematic embodiment, the outer peripheral wall of the scale removal 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 both be circular rings and surround the scale removal bracket 51. The first annular groove 514 can be arranged below the second annular groove 515. The first annular groove 514 and the second annular groove 515 are spaced apart and not communicated with each other. The first opening 512 is arranged at the bottom of the first annular groove 514. The second opening 513 is arranged at the bottom of the second annular groove 515.

[0080] The installation cylinder 11 is sleeved on the scale inhibitor support 51, and the inner peripheral wall of the installation cylinder 11 covers the openings of the first annular groove 514 and the second annular groove 515 of the scale inhibitor support 51. The first water inlet hole 115 on the installation cylinder 11 is flush with the first annular groove 514 of the scale inhibitor support 51 in the axial direction of the installation cylinder 11, and one end of the first water inlet hole 115 of the installation cylinder 11 facing inward is connected to the first annular groove 514. The first water outlet 113 of the installation cylinder 11 is flush with the second annular groove 515 of the scale inhibitor support 51 in the axial direction of the installation cylinder 11, and the first water outlet 113 of the installation cylinder 11 is connected to the second annular groove 515.

[0081] In this way, the first water inlet hole 115 on the installation cylinder 11 can communicate with the first opening 512 of the scale inhibitor support 51 through the first annular groove 514, and the first water outlet 113 on the installation cylinder 11 can communicate with the second opening 513 of the scale inhibitor support 51 through the second annular groove 515. Therefore, it is not necessary to require the first water inlet hole 115 to be precisely aligned with the first opening 512, nor is it necessary to require the first water outlet 113 to be precisely aligned with the second opening 513, reducing the requirement for the fitting accuracy between the installation cylinder 11 and the scale inhibitor support 51, and making production and installation more convenient.

[0082] In a schematic embodiment, as Figure 15 shown, a handle 516 is provided at one end of the scale inhibitor support 51 facing away from the installation support 1, and the handle 516 extends out of the installation cylinder 11. The handle 516 can be configured as a plate-like structure.

[0083] The user can operate the handle 516 to rotate the scale inhibitor support 51, making it more convenient to disassemble and assemble the scale inhibitor support 51.

[0084] In a schematic embodiment, as Figure 16 shown, an internal thread 116 is provided on the inner peripheral wall of the installation cylinder 11. An external thread 517 that is screwed with the internal thread 116 is provided on the outer peripheral wall of the scale inhibitor support 51. The external thread 517 of the scale inhibitor support 51 can be provided at one end of the scale inhibitor support 51 close to the filter support 41.

[0085] A threaded connection is formed between the scale inhibitor support 51 and the installation cylinder 11 through the cooperation of the internal thread 116 and the external thread 517. The scale inhibitor support 51 can be disassembled and assembled only by rotating the scale inhibitor support 51 relative to the installation cylinder 11, making the disassembly and assembly of the scale inhibitor support 51 more convenient.

[0086] In a schematic embodiment, as Figure 15 、 16 shown, a second water outlet 112 is further provided on the installation support 1. A water passage that connects the first water inlet 111 and the second water outlet 112 is provided inside the installation support 1.

[0087] As Figure 14 , 20 , as shown in Fig. 21, the water inlet assembly 100 further includes a flushing valve 2. The flushing valve 2 can be a single pulse valve. The flushing valve 2 is provided with a water inlet 21 and a water outlet 22. The flushing valve 2 is connected to the mounting bracket 1. The water inlet 21 of the flushing valve 2 communicates with the second water outlet 112 of the mounting bracket 1. The water outlet 22 of the flushing valve 2 is used to connect to the brush ring nozzle. The flushing valve 2 can open and close the second water outlet 112 of the mounting bracket 1. The second water outlet 112 of the mounting bracket 1 can supply water to the brush ring nozzle of the toilet. The brush ring nozzle is used to flush the toilet bowl.

[0088] The first water outlet 113 is used to supply water to the body cleaning component and the foam generating component of the toilet. The body cleaning component is used to flush the vulva, buttocks, etc. The foam generating component is used to generate foam and transport the foam to the toilet bowl. The foam has the functions of preventing splashing water, cleaning the toilet bowl, and preventing odors.

[0089] Thus, as Figure 15 shown, when the flushing valve 2 is opened, water flows from the first water inlet 111 into the mounting bracket 1, and then is output from the second water outlet 112 of the mounting bracket 1. The second water outlet 112 can supply water to the brush ring nozzle of the toilet, thereby flushing the toilet. When the flushing valve 2 is closed, the second water outlet 112 stops discharging water.

[0090] Thus, 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 path is transported to the brush ring nozzle of the toilet as toilet flushing water, and the other path is transported to the body cleaning component and the foam generating component as body cleaning water and foam liquid dilution water respectively. Thus, the toilet flushing water and the body cleaning water can be effectively separated, avoiding the pollution of the body cleaning water by the toilet flushing water. The water inlet assembly 100 has a high integration degree, a compact structure, and occupies a small space.

[0091] In a schematic embodiment, the water inlet assembly 100 further includes a third valve 7. The third valve 7 is arranged at the first water inlet 111. The filter bracket 41 is arranged between the third valve 7 and the scale inhibitor. The filter bracket 41 presses the third valve 7. The third valve 7 is configured to open the first water inlet 111 when being pressed by the filter bracket 41 and close the first water inlet 111 when not being pressed by the filter bracket 41.

[0092] When both the first filter assembly 4 and the second filter assembly 5 are installed in the installation cylinder 11, the third valve 7 is opened, and water can be input from the first water inlet 111 into the installation cylinder 11. After the first filter assembly 4 and the second filter assembly 5 are removed from the installation cylinder 11, the filter bracket 41 no longer presses the third valve 7, the third valve 7 closes, and water cannot be input from the first water inlet 111 into the installation cylinder 11.

[0093] In this way, without closing the water source, the user can remove the first filtering component 4 and the second filtering component 5 from the installation cylinder 11. After removing the first filtering component 4 and the second filtering component 5, the third valve 7 closes the first water inlet 111, and water will not flow out of the installation cylinder 11. After reinstalling the first filtering component 4 and the second filtering component 5 into the installation cylinder 11, the third valve 7 is squeezed by the filtering bracket 41 and reopened, and the first water inlet 111 can intake water again. Thus, it is more convenient for the user to replace the scale inhibitor 52.

[0094] In a schematic embodiment, as Figure 14 、 17 shown, the third valve 7 includes a seat body 71, a sealing gasket 77, a closing member 75 and an elastic member 74. The seat body 71 includes 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 disposed in the installation cylinder 11, and the outer peripheral wall of the valve seat 711 abuts against the inner peripheral wall of the installation cylinder 11. The valve seat 711 is provided with an internal passage.

[0095] The connecting seat 712 is located on the side of the valve seat 711 facing away from the filtering bracket 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 slideway, which is straight and coaxially arranged with the valve seat 711, and the slideway penetrates through the connecting seat 712.

[0096] 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. A plurality of connecting portions 713 can be provided, and the plurality of connecting portions 713 are evenly distributed in the circumferential direction of the connecting seat 712.

[0097] The sealing gasket 77 has flexibility. 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 disposed 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.

[0098] The closing member 75 includes 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 slideway of the connecting portion 713. The valve rod 751 has a clearance fit with the slideway. The valve rod 751 can slide along the slideway.

[0099] The valve flap 752 can be configured as a disc shape. The valve flap 752 is disposed between the gasket 77 and the connecting seat 712. The valve flap 752 is connected to one end of the valve stem 751 close to the valve seat 711. The valve flap 752 and the gasket 77 can be coaxially arranged. The diameter of the valve flap 752 is larger than the diameter of the inner channel of the gasket 77. The valve flap 752 can block one end of the inner channel of the gasket 77 facing the valve flap 752.

[0100] The elastic member 74 can be a compression spring. One end of the elastic member 74 abuts against one end of the valve flap 752 facing the connecting seat 712, and the other end of the elastic member 74 abuts against one end of the connecting seat 712 facing the valve flap 752. The elastic member 74 is in a compressed state. The elastic member 74 applies an elastic force to the valve flap 752 towards the gasket 77.

[0101] When the first filter assembly 4 and the second filter assembly 5 are installed in the cylinder body, one end of the filter bracket 41 facing away from the scale inhibitor bracket 51 presses the valve flap 752 so that the valve flap 752 and the gasket 77 are separated.

[0102] In this way, when the first filter assembly 4 and the second filter assembly 5 are installed in the cylinder body, the filter bracket 41 presses the valve flap 752 so that the valve flap 752 and the gasket 77 of the third valve 7 are separated from each other, and the third valve 7 is opened. After water is input from the first water inlet 111 into the installation cylinder 11, it can flow through the gap between the valve seat 711 and the valve flap 752, the inner channel of the gasket, and the inner channel of the valve seat 711 in sequence to reach the second water outlet 112 and the filter inlet 4111 of the filter bracket 41. After the first filter assembly 4 and the second filter assembly 5 are removed from the cylinder body, the valve flap 752 moves under the elastic force of the elastic member 74 to abut against the gasket and block the inner channel of the gasket, and the third valve 7 is closed, and water cannot pass through the inner channel of the gasket to reach the second water outlet 112 and the filter inlet 4111 of the filter bracket 41.

[0103] In a schematic embodiment, as Figure 13 shown, the water inlet assembly 100 further includes a battery 84. The battery 84 can be configured as a rectangle. The battery 84 is electrically connected to the electrical devices of the toilet, and the battery 84 supplies power to these electrical devices. The battery 84 can supply power to the flushing valve 2 and some electrical devices of the flushing system during a power outage.

[0104] As Figure 12 、 13As shown, the mounting bracket 1 further includes a battery compartment 12 and a foam liquid compartment 13. The water inlet assembly 100 further includes a battery cover 81 and a liquid filling cover 82. The battery compartment 12 is used to accommodate the battery 84 and protect the battery 84 from being soiled by water and dust. The foam liquid compartment 13 is used to add foam liquid. A foam liquid outlet is provided on the foam liquid compartment 13, and the foam liquid outlet is connected to the foam generating assembly of the toilet through a pipeline. Both the battery compartment 12 and the foam liquid compartment 13 are provided on the side of the mounting cylinder 11 at the end facing away from the water inlet. The battery compartment 12, the foam liquid compartment 13 and the mounting cylinder 11 can be integrally formed structures. Openings can be provided at the tops of the battery compartment 12 and the foam liquid compartment 13. The battery cover 81 can cover the opening of the battery compartment 12 to seal the opening. The liquid filling cover 82 can cover the opening of the foam liquid compartment 13 and seal the opening.

[0105] In this way, the battery 84 and the foam liquid are respectively accommodated in the battery compartment 12 and the foam liquid compartment 13, and the battery compartment 12 and the foam liquid compartment 13 are arranged at the top of the mounting cylinder 11, which is convenient for replacing the battery 84 and adding the foam liquid, and makes the overall structure of the water inlet assembly 100 compact and small in occupied volume.

[0106] In a schematic embodiment, the water inlet valve 3 includes a water channel body 30. A water inlet 31, a water outlet 32 and a water flow channel 33 extending from the water inlet 31 to the water outlet 32 are provided on the water channel body 30.

[0107] As Figure 19 shown, the water inlet valve 3 includes a solenoid valve 36, a flow restrictor 34 and a water inlet check valve 35. The solenoid valve 36, the flow restrictor 34 and the water inlet check valve 35 are arranged in sequence on the water flow channel 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 the water flow flowing from the water inlet 31 of the water channel body 30 to the water outlet 32 of the water channel body 30. The water inlet check valve 35 can prevent the reverse flow of water. The flow restrictor 34 is configured to adjust the water flow rate flowing through the water flow channel 33. The flow restrictor 34 can limit the water flow rate flowing through the water inlet valve 3, and can further prevent the water pressure of the water flow input into the second filter assembly 5 from being too high and causing the second filter assembly 5 to burst.

[0108] In a schematic embodiment, as Figure 20 、 21 shown, the mounting bracket 1 further includes a water outlet joint 117. The water outlet joint 117 is provided on the outer side wall of the mounting cylinder 11. The water outlet joint 117 is connected to the second water outlet 112 of the mounting cylinder 11.

[0109] As Figure 20As shown, the water inlet assembly 100 further includes a flushing adapter 9. The flushing adapter 9 includes a water inlet joint 91, a bent pipe 92, and a clamping seat 93. The water inlet joint 91 is inserted into the water outlet joint 117 of the mounting bracket 1. The bent pipe 92 can be configured as a bent pipe 92 with a right-angle bend. One end of the bent pipe 92 is connected to the water inlet joint 91, and the other end of the bent pipe 92 extends upward. The clamping seat 93 is connected to one end of the bent pipe 92 facing away from the water inlet joint 91. One end of the flushing valve 2 provided with a water inlet is snap-connected to the clamping seat 93. The water outlet 22 of the flushing valve 2 is used to connect to the brush ring nozzle.

[0110] In this way, the flushing valve 2 is transferred to the mounting cylinder 11 through the water outlet joint 117, and the water outlet joint 117 connects the water inlet 21 of the flushing valve 2 and the second water outlet 112 of the mounting cylinder 11, so that the position of the flushing valve 2 can be arranged more flexibly.

[0111] In a schematic embodiment, the clamping seat 93 is configured as a ring. A clamping groove 931 is provided on the inner wall of the clamping seat 93. The clamping groove 931 extends along the circumferential direction of the clamping seat 93. One end of the clamping groove 931 is provided with a disassembly and assembly opening 932.

[0112] A protrusion 23 is provided on the outer peripheral wall of one end of the flushing valve 2 provided with a water inlet. The protrusion 23 can be strip-shaped, and the protrusion 23 extends along the circumferential direction of the outer peripheral wall of the flushing valve 2. The protrusion 23 is received in the clamping groove 931 of the clamping seat 93. The length of the protrusion 23 is less than the width of the disassembly and assembly opening 932 of the clamping seat 93, so that the protrusion 23 can pass through the disassembly and assembly opening 932.

[0113] In this way, when it is necessary to install the flushing valve 2 onto the clamping seat 93, insert the flushing valve 2 into the clamping seat 93 so that the protrusion 23 is aligned with the disassembly and assembly opening 932, and then rotate the flushing valve 2 so that the protrusion 23 slides along the clamping groove 931 and enters the clamping groove 931, thereby realizing the snap connection between the flushing valve 2 and the clamping seat 93. When it is necessary to disassemble the flushing valve 2 from the clamping seat 93, only need to rotate the flushing valve 2 so that the protrusion 23 moves out of the clamping groove 931 from the disassembly and assembly opening 932, and then pull out the flushing valve 2 from the clamping seat 93.

[0114] In a schematic embodiment, as Figure 13 shown, the water inlet assembly 100 further includes a radio frequency module 6. The radio frequency module 6 is used for wireless communication with the remote control. 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 snap-connected to the clamping seat 93.

[0115] The radio frequency module 6 is connected to the flushing adapter 9, which can make full use of the space on one side of the flushing adapter 9, making the overall structure of the water inlet assembly 100 more compact and occupying less volume.

[0116] In a schematic embodiment, as Figure 11 and 14 shown, the water inlet assembly 100 further includes a water delivery pipe 83. Two ends of the water delivery pipe 83 are respectively connected to the water outlet 32 of the water inlet valve 3 and the first water inlet hole 115 of the installation cylinder 11. The water outlet 32 of the water inlet valve 3 and the first water inlet hole 115 of the installation cylinder 11 are communicated through the water delivery pipe 83.

[0117] This embodiment also proposes a toilet, which includes the above-mentioned water inlet assembly 100, the above-mentioned body cleaning assembly, the above-mentioned brush ring nozzle, the foam generating assembly and a ceramic toilet.

[0118] A fecal cavity is provided on the ceramic toilet.

The brush ring nozzle is arranged at the top of the fecal cavity. The brush-out nozzle is communicated with the water outlet 22 of the flushing valve 2 through a pipeline. The brush-out nozzle can spray the water output by the flushing valve 2 into the fecal cavity to flush the fecal cavity. The body cleaning assembly and the foam generating assembly are communicated with the first water outlet 113 of the water inlet assembly 100. The body cleaning assembly is arranged on one side of the fecal cavity. The body cleaning assembly is provided with a nozzle that sprays water upward. A heating device or an instant heating assembly can heat the water output from the first water outlet 113 and spray the heated water from the nozzle. The foam outlet of the foam generating assembly is communicated with the fecal 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 from the foam outlet into the fecal cavity.
