Description
TECHNICAL FIELD
[0001] The present disclosure relates to the technical field of bathroom, in particular to a toilet, a foam generating assembly and a liquid adding assembly. BACKGROUND
[0002] The intelligent toilet is more and more popular in modern life. Some existing intelligent toilets are provided with a foam generator, which can deliver foam into the bowl of a ceramic toilet, and the foam can prevent water splashing and clean the bowl.
[0003] However, after the foam liquid in the liquid adding of the intelligent toilet is used up, the user adds the foam liquid to the liquid supplementing cavity again, and the foam generator starts to produce foam for several times, the effect is very poor, such as the foam is few, or even no foam can be produced, and the user experience is poor. SUMMARY
[0004] The technical problem to be solved by the present application is how to make the foam generator normally produce foam at the first time after the foam liquid is added.
[0005] To solve the above technical problem, the present application provides a liquid adding assembly for adding foam liquid, which comprises:
[0006] A mounting bracket comprising a liquid supplementing cavity, a liquid supplementing opening and a liquid outlet opening, the liquid outlet opening being used for delivering the foam liquid to the foam generator;
[0007] A liquid supplementing switch arranged on the liquid supplementing cavity;
[0008] A liquid adding cover covering the liquid supplementing opening and pressing the liquid supplementing switch;
[0009] The liquid supplementing switch is configured to send a liquid supplementing instruction when being pressed by the liquid adding cover, and the liquid supplementing instruction is used for instructing the liquid pumping pump of the foam generator to pump the foam liquid to the liquid mixing cavity of the foam generator.
[0010] When the foam generator no longer outputs foam, it indicates that the foam liquid in the foam generator has been consumed, the concentration of the foam liquid in the liquid mixing cavity is very small, and the foam liquid needs to be added again. The user removes the liquid adding cover on the liquid supplementing opening, then adds the foam liquid to the liquid supplementing opening, the foam liquid enters the liquid supplementing cavity from the liquid supplementing opening, and the foam liquid in the liquid supplementing cavity is delivered to the foam generator through the liquid outlet opening. After the addition of the foam liquid is completed, the user re-covers the liquid adding cover on the liquid supplementing opening.
[0011] When the user detaches the liquid adding cover, the liquid supplementing switch is not pressed by the liquid adding cover any more, and when the user reattaches the liquid adding cover to the liquid supplementing port, the liquid adding cover presses the liquid supplementing switch again. Therefore, when the user finishes adding the foam liquid and covers the liquid adding cover, the liquid supplementing switch is switched from the state of not being pressed by the liquid adding cover to the state of being pressed by the liquid adding cover, the liquid supplementing switch sends a liquid supplementing instruction, and the liquid pumping pump of the foam generating device pumps the foam liquid into the mixed liquid chamber of the foam generator, so as to increase the concentration of the dilute foam liquid in the mixed liquid chamber. In this way, when the foam generator first generates foam after the foam liquid is supplemented, the concentration of the dilute foam liquid in the mixed liquid chamber is increased, and the bubble device can smoothly generate foam after the dilute foam liquid is delivered to the bubble device.
[0012] Other features and advantages of the present application will be set forth in the following description, and in part will be apparent from the description, or can be learned by practice of the present application. Other advantages of the present application will be realized and attained by the solution described in the specification and the accompanying drawings. BRIEF DESCRIPTION OF DRAWINGS

[0041] As Figure 1 , 2 shown, Figure 1 , 2 shows a foam generating assembly 1000 in embodiments of the present application. The foam generating assembly 1000 comprises a foam generator 200, a liquid adding assembly 100 and a controller.
[0042] As Figure 2 shown, the liquid adding assembly 100 comprises a mounting bracket 1, a liquid supplementing switch 9 and a liquid adding cover 82. As Figures 3-5 shown, the mounting bracket 1 is provided with a liquid supplementing bin 13. The liquid supplementing bin 13 can be configured as a substantially box-shaped structure. The liquid supplementing bin 13 comprises a liquid supplementing port 131, a liquid outlet port 132 and a liquid supplementing cavity 130. The liquid supplementing port 131 can be provided at a top end of the liquid supplementing bin 13 and communicates with the liquid supplementing cavity 130. The liquid outlet port 132 can be provided at a bottom end of the liquid supplementing bin 13 and communicates with the liquid supplementing cavity 130. The liquid outlet port 132 communicates with the foam generator 200 and is used to deliver the foam liquid to the foam generator 200. After the user adds the foam liquid into the liquid supplementing cavity 130 through the liquid supplementing port 131, the foam liquid enters the liquid supplementing cavity 130 and is outputted from the liquid outlet port 132 to the foam generator 200.
[0043] As Figure 8As shown, the liquid adding cap 82 is in a state of covering the liquid supplementing opening 131. The liquid adding cap 82 is used to close the liquid supplementing opening 131 of the liquid supplementing container 13. The liquid adding cap 82 is detachably connected with the liquid supplementing container 13. The user can detach the liquid adding cap 82 from the liquid supplementing opening 131 of the liquid supplementing container 13.
[0044] The liquid supplementing switch 9 is arranged on the liquid supplementing container 13 and is located at a position capable of contacting the liquid adding cap 82. As shown, Figure 8 As shown, the liquid adding cap 82 is in a state of covering the liquid supplementing opening 131 and presses the liquid supplementing switch 9. As shown, Figure 7 As shown, the liquid adding cap 82 is in a state of covering the liquid supplementing opening 131 and presses the liquid supplementing switch 9. As shown,
[0045] As shown, Figure 1 、 9 The foam generator 200 includes a casing 21, a liquid pumping device 22 and a foaming device (not shown). The casing 21 can be configured as a substantially cuboid structure. The casing 21 is internally provided with a liquid storage cavity 211 and a liquid mixing cavity 212. The liquid storage cavity 211 and the liquid mixing cavity 212 can be arranged side by side. The casing 21 is further provided with a foam liquid inlet 213, an exhaust opening 214, a dilution water inlet 215 and a mixed liquid outlet 216. The foam liquid inlet 213 and the exhaust opening 214 are both communicated with the liquid storage cavity 211. The liquid outlet 132 of the mounting bracket 1 is communicated with the foam liquid inlet 213, and the foam liquid output by the liquid outlet 132 can be input into the liquid storage cavity 211 through the foam liquid inlet 213 for storage. The exhaust opening 214 is arranged at the top of the liquid mixing cavity 212 and is used to exhaust air in the liquid storage cavity 211 when the foam liquid is input into the liquid storage cavity 211 from the foam liquid inlet 213. The dilution water inlet 215 and the mixed liquid outlet 216 are both communicated with the liquid mixing cavity 212. The dilution water inlet 215 is used to receive dilution water, which can be filtered tap water.
[0046] The liquid pumping device 22 is connected with the casing 21. The liquid pumping device 22 can be arranged below the casing 21. The liquid pumping device 22 is provided with an input port 221 and an output port 222. The input port 221 of the liquid pumping device 22 is communicated with the liquid storage cavity 211, and the output port 222 of the liquid pumping device 22 is communicated with the liquid mixing cavity 212. The liquid pumping device 22 can pump the foam liquid in the liquid storage cavity 211 to the liquid mixing cavity 212 when the liquid pumping device 22 is operated. The foaming device is communicated with the mixed liquid outlet 216 through a pipeline. The foaming device is used to mix air and the dilution foam liquid output by the mixed liquid outlet 216 into foam.
[0047] As shown, Figure 9As shown, the pump 22 pumps the foaming liquid from the storage chamber 211 to the mixing chamber 212. Diluent water is supplied from the diluent water inlet 215 to the mixing chamber 212 to dilute the foaming liquid within it. The diluent water and foaming liquid mix in the mixing chamber 212 to form a diluted foaming liquid, which is then supplied to the foaming device through the mixed liquid outlet 216. The foaming device can mix air and the diluted foaming liquid to form foam.
[0048] The controller is a logic control unit. It can be a microcomputer or a microcontroller. The controller is electrically connected to the pump 22 and the replenishment switch 9 via wires. The controller is configured to drive the pump 22 to pump the foam liquid from the storage chamber 211 to the mixing chamber 212 upon receiving a replenishment command. The controller can control the pump 22 to run for a preset time, ensuring that the concentration of the foam liquid in the mixing chamber 212 is greater than or equal to the lower limit of the foam liquid concentration required to mix with air and generate foam. The preset time can be pre-calibrated, for example, from 8ms to 200ms.
[0049] When the foam generator 200 stops outputting foam, it indicates that the foam concentrate in the foam generator 200 has been depleted, and the concentration of the foam concentrate in the mixing chamber 212 is very low, requiring refilling. The user removes the filler cap 82 from the filler port 131 and then adds foam concentrate to the filler port 131. The foam concentrate enters the filler chamber 130 from the filler port 131, and the foam concentrate in the filler chamber 130 is then transported to the storage chamber 211 of the foam generator 200 through the outlet 132. After the foam concentrate has been added, the user replaces the filler cap 82 on the filler port 131.
[0050] like Figure 7 As shown, when the user removes the filler cap 82, the filler switch 9 is no longer squeezed by the filler cap 82, as... Figure 8 As shown, when the user closes the filling cap 82 back onto the replenishment port 131, the filling cap 82 presses the replenishment switch 9 again. Therefore, when the user finishes adding foaming liquid and closes the filling cap 82, the replenishment switch 9 changes from a state where it was not pressed by the filling cap 82 to a state where it is pressed by the filling cap 82. The replenishment switch 9 issues a replenishment command, and the pump 22 of the foam generator pumps foaming liquid into the mixing chamber 212 of the foam generator 200, thereby increasing the concentration of diluted foaming liquid in the mixing chamber 212. In this way, when the foam generator 200 produces foam for the first time immediately after replenishing the foaming liquid, because the concentration of diluted foaming liquid in the mixing chamber 212 is increased, this diluted foaming liquid is transported to the foaming device, and the bubble device can successfully produce foam.
[0051] In one illustrative embodiment, such as Figure 6As shown, the liquid supplement switch 9 comprises an insulating shell 91, a conductive contact 92 and an elastic conductive sheet 93. The insulating shell 91 is made of insulating material, such as plastic. The insulating shell 91 is in a thin shell structure. The insulating shell 91 is provided with a mounting cavity 90, and the wall surface of the mounting cavity 90 is provided with a mounting hole 911. The mounting hole 911 is a through hole. The insulating shell 91 is connected to the liquid supplement bin 13, and the mounting hole 911 is arranged on the side wall of the side of the insulating shell 91 facing the liquid supplement bin 13.
[0052] The conductive contact 92 is made of conductive material and can conduct electricity. The conductive contact 92 can be made of metal material. The conductive contact 92 comprises a body part 922 and a contact part 921. The body part 922 is arranged in the mounting cavity 90. The contact part 921 is connected to the body part 922, and the contact part 921 penetrates the mounting hole 911. The end of the contact part 921 away from the body part 922 extends out of the insulating shell 91.
[0053] The elastic conductive sheet 93 is made of conductive material, such as metal material. The elastic conductive sheet 93 is elastic and can be elastically deformed by bending. The elastic conductive sheet 93 can be configured in a sheet structure, such as a strip-shaped sheet structure. The elastic conductive sheet 93 comprises a first end 931 and a second end 932 opposite to the first end 931. The elastic conductive sheet 93 is arranged outside the insulating shell 91. The first end 931 of the elastic conductive sheet 93 is connected to the outer side wall of the insulating shell 91. The elastic conductive sheet 93 is arranged on the side of the contact part 921 of the conductive contact 92 close to the liquid supplement cover 82.
[0054] When the liquid supplement cover 82 is not covered on the liquid supplement port 131, the liquid supplement cover 82 is separated from the elastic conductive sheet 93, and there is a gap between the elastic conductive sheet 93 and the conductive contact 92. At this time, the elastic conductive sheet 93 and the conductive contact 92 are not in conduction, and the liquid supplement switch 9 is in an open state.
[0055] When the liquid supplement cover 82 is covered on the liquid supplement port 131, the liquid supplement cover 82 presses the elastic conductive sheet 93 close to the conductive contact 92, so that the elastic conductive sheet 93 is elastically deformed and bent, thereby being in contact with the conductive contact 92. At this time, the elastic conductive sheet 93 and the conductive contact 92 are in electrical conduction, and the liquid supplement switch 9 is in a closed state.
[0056] The elastic conductive sheet 93 and the conductive contact 92 are respectively connected to the controller through two wires. The controller can determine whether the liquid supplement switch 9 issues a liquid supplement instruction by detecting the change of the working state of the liquid supplement switch 9. The transition of the liquid supplement switch 9 from the open state to the closed state represents that the liquid supplement switch 9 issues a liquid supplement instruction.
[0057] In an illustrative embodiment, as shown in Figure 4As shown, the liquid supplement opening 131 is arranged at the top end of the liquid supplement compartment 13, and is enclosed by the top end of the sidewall of the liquid supplement compartment 13.
[0058] The liquid supplement cover 82 comprises a top cover 821, a plug-in portion 822 and a handle 823. The top cover 821 is configured as a substantially plate structure. The top cover 821 covers the liquid supplement opening 131 and seals the liquid supplement opening 131. The plug-in portion 822 can be configured as a cylindrical structure. One end of the plug-in portion 822 is connected to the top cover 821. The cross-sectional shape of the plug-in portion 822 is the same as the cross-sectional shape of the liquid supplement cavity 130. The plug-in portion 822 is inserted into the liquid supplement cavity 130 from the top cover 821. The sidewall of the plug-in portion 822 abuts against the sidewall of the liquid supplement cavity 130. The handle 823 is arranged on the side of the top cover 821 away from the plug-in portion 822. The handle 823 can be configured as a flat plate structure perpendicular to the top cover 821.
[0059] The liquid supplement switch 9 is arranged on the sidewall of the liquid supplement compartment 13. The second end 932 of the elastic conductive sheet 93 extends into the liquid supplement cavity 130. When the liquid supplement cover 82 covers the liquid supplement opening 131, the sidewall of the plug-in portion 822 presses the second end 932 of the elastic conductive sheet 93 towards the contact portion 921 of the conductive contact 92, so that the elastic conductive sheet 93 abuts against the contact portion 921 of the conductive contact 92. When the liquid supplement cover 82 does not cover the liquid supplement opening 131, the plug-in portion 822 is separated from the second end 932 of the elastic conductive sheet 93. The elastic conductive sheet 93 returns to the state of being separated from the contact portion 921 of the conductive contact 92 under the action of the elastic force.
[0060] In this way, the user can hold the handle of the liquid supplement cover 82 to operate the liquid supplement cover 82, which is more convenient. Meanwhile, when the liquid supplement cover 82 covers the liquid supplement opening 131, the plug-in portion 822 of the liquid supplement cover 82 is inserted into the liquid supplement cavity 130, so that the liquid supplement cover 82 can be more stably mounted on the liquid supplement compartment 13. In particular, the liquid supplement switch 9 is arranged on the sidewall of the liquid supplement compartment 13. The pressure applied by the second end 932 of the elastic conductive sheet 93 to the plug-in portion 822 of the liquid supplement cover 82 is perpendicular to the plug-in direction of the plug-in portion 822. The pressure applied by the elastic conductive sheet 93 to the plug-in portion 822 cannot push the pressure cover, so that the liquid supplement cover 82 cannot be tightly covered on the liquid supplement opening 131.
[0061] In one illustrative embodiment, as shown in Figure 6 , 7 shown, the elastic conductive sheet 93 is arranged obliquely. The first end 931 of the elastic conductive sheet 93 is directed towards the liquid supplement opening 131, and the second end 932 of the elastic conductive sheet 93 is directed towards the bottom wall of the liquid supplement cavity 130. In the direction from the first end 931 of the elastic conductive sheet 93 to the second end 932 of the elastic conductive sheet 93, the distance of the elastic conductive sheet 93 to the insulating shell 91 gradually increases.
[0062] Since the distance of the elastic conductive sheet 93 to the insulating shell 91 gradually increases from the first end 931 to the second end 932, and the second end 932 of the elastic conductive sheet 93 is towards the bottom wall of the liquid supplementing cavity 130, the elastic conductive sheet 93 is inclined to the plug-in direction of the plug-in part 822 of the liquid supplementing cover 82, and the plug-in part 822 slides along the elastic conductive sheet 93 from the first end 931 to the second end 932 during the process of being inserted into the liquid supplementing cavity 130, so that the plug-in process of the plug-in part 822 is smoother, and the user experience is better.
[0063] In an illustrative embodiment, as shown in Figure 3 、 7 the first through hole 133 is arranged on the side wall of the liquid supplementing bin 13. The first through hole 133 communicates with the liquid supplementing cavity 130. The first through hole 133 penetrates through the side wall of the liquid supplementing bin 13. The first through hole 133 can be configured as a rectangular through hole.
[0064] The insulating shell 91 is arranged on the outer side wall of the liquid supplementing cavity 130, and the insulating shell 91 blocks the first through hole 133 on the liquid supplementing bin 13. The mounting hole 911 of the insulating shell 91 is located on the side of the insulating shell 91 close to the first through hole 133, and the first through hole 133 and the mounting hole 911 are aligned with each other. The elastic conductive sheet 93 is arranged in the first through hole 133 of the liquid supplementing bin 13, and the first end 931 of the elastic conductive sheet 93 is located outside the liquid supplementing cavity 130, and the second end 932 of the elastic conductive sheet 93 is located inside the liquid supplementing cavity 130.
[0065] The insulating shell 91 and the conductive contact 92 are both located outside the liquid supplementing bin 13, and only the second end 932 of the elastic conductive sheet 93 extends into the liquid supplementing bin 13 through the first through hole 133, so that the foam liquid in the liquid supplementing cavity 130 can be avoided from flowing onto the insulating shell 91 and the conductive contact 92 as much as possible, thereby reducing the influence on the conductivity between the conductive contact 92 and the elastic conductive sheet 93.
[0066] In an illustrative embodiment, the mounting bracket 1 further comprises a mounting cylinder 11. The mounting cylinder 11 is connected to the liquid supplementing bin 13. The mounting cylinder 11 is provided with a first water inlet 111 and a first water outlet 113. The first water inlet 111 and the first water outlet 113 are connected through a water path. The first water inlet 111 is used for connecting an external tap water supply pipe. The first water outlet 113 is connected to the dilution water inlet 215 of the foam generator 200, and is used for delivering dilution water to the foam generator 200.
[0067] The liquid supplementing assembly 100 further comprises a filtering module. The filtering module is arranged in the mounting cylinder 11. The filtering module is arranged on the water path between the first water inlet 111 and the first water outlet 113, and is used for filtering the water flowing from the first water inlet 111 to the first water outlet 113.
[0068] In this way, water flows sequentially through the first inlet 111, the filter module, and the first outlet 113, and then from the first outlet 113 is delivered to the mixing chamber 212 of the foam generator 200 as dilution water to dilute the foam liquid. Because the water is filtered when it flows through the filter module, impurities in the water are removed, preventing impurities from entering the foam generator 200 and causing damage to it.
[0069] In one illustrative embodiment, the mounting cylinder 11 may be vertically oriented, having an upward-facing top end and a downward-facing bottom end. A replenishment tank 13 is disposed on one side of the top end of the mounting cylinder 11. The replenishment tank 13 and the mounting cylinder 11 may be integrally formed. The filter module can be inserted into the mounting cylinder 11 from its top end.
[0070] In this way, the top of the liquid filling port 131 on the liquid filling tank 13 and the top of the mounting cylinder 11 are both facing upwards, making it convenient for users to remove and install the liquid filling cap 82 and insert the filter module from the top of the liquid filling assembly 100.
[0071] In one illustrative embodiment, the filter module 1a includes a first filter component 4 and a second filter component 5. The first filter component 4 is connected to the second filter component 5. The first filter component 4 and the second filter component 5 are arranged sequentially along the axial direction of the mounting cylinder 11.
[0072] The first filter assembly 4 includes a filter support 41 and a filter medium 42. The filter support 41 is provided with a filter inlet 4111, a filter outlet 4112, and a filter channel. The filter channel is disposed within the filter support 41 and extends from the filter inlet 4111 to the filter outlet 4112. The shape of the filter channel is not limited; the filter channel can be a straight channel or a curved channel.
[0073] like Figure 11 , 13 As shown, the filter medium 42 is fixed on the filter support 41 and disposed within the filter channel 4113. The filter medium 42 is used to filter solid particulate impurities from the water. The filter medium 42 can be a filter screen with multiple mesh openings, the mesh size of which can be 100 mesh. This filter screen can be, for example, a nylon mesh or a metal mesh. The filter medium 42 can also be granular media, porous media, activated carbon, diatomaceous earth, gauze, canvas, filter paper, filter membrane, polypropylene fiber, polyester fiber, polytetrafluoroethylene, or glass fiber. When water flows through the filter medium 42 in the filter channel, solid particulate impurities in the water are filtered out.
[0074] The second filter assembly 5 comprises a scale inhibitor holder 51 and a scale inhibitor 52. The scale inhibitor holder 51 is connected to the filter holder 41. The scale inhibitor holder 51 is provided with a first opening 512 and a second opening 513. The scale inhibitor holder 51 is provided with a scale inhibitor cavity 511. The scale inhibitor cavity 511 can be a cylindrical cavity. The first opening 512 and the second opening 513 are both through-holes penetrating the wall of the scale inhibitor cavity 511. The first opening 512 and the second opening 513 are both connected to the scale inhibitor cavity 511.
[0075] The scale inhibitor 52 is filled in the scale inhibitor cavity 511. The scale inhibitor 52 can be in the form of solid particles or in the form of a block with porous structure. The scale inhibitor 52 has the function of dispersing the insoluble inorganic salts in water and preventing or interfering the precipitation of the insoluble inorganic salts on the metal surface in the water path and the cavity of the components. The scale inhibitor 52 can be in the form of solid particles or in the form of a block with porous structure. The scale inhibitor 52 is filled in the scale inhibitor cavity 511 of the scale inhibitor holder 51. When the water flows through the scale inhibitor cavity 511, the scale inhibitor 52 can chelate the metal cations in the water.
[0076] The distance from the first opening 512 and the second opening 513 of the scale inhibitor holder 51 to the filter outlet 4112 of the filter holder 41 is different. The filter outlet 4112 of the filter holder 41 is connected to the first opening 512. The filter outlet 4112 can be connected to the first opening 512 through a water path or a valve. The filter outlet is connected to the first opening 512 through a water path. The second opening 513 is connected to the first water outlet 113 through a water path.
[0077] In this way, the water enters the first opening 512, then enters the filter inlet 4111, and then enters the filter flow channel of the filter holder 41. The solid particle impurities in the water are filtered out when the water flows through the filter flow channel. The filtered water is then delivered to the scale removal cavity through the filter outlet 4112. The scale inhibitor 52 can chelate the metal cations in the water when the water flows through the scale removal cavity, preventing the formation of scale. The water in the scale removal cavity flows from the second opening 513 to the first water outlet 113, and finally is delivered to the mixing cavity 212 of the foam generator 200 as dilution water, preventing scale formation in the foam generator 200.
[0078] In an exemplary embodiment, the filter holder 41 is arranged below the scale inhibitor holder 51, and the first opening 512 of the scale inhibitor holder 51 is arranged below the second opening 513 of the scale inhibitor holder 51.
[0079] In this way, the filter outlet 4112 of the filter holder 41 can be connected to the first opening 512, so that the lower first opening 512 is used for water inlet and the higher second opening 513 is used for water outlet. The filter outlet 4112 of the filter holder 41 can be connected to the second opening 513, so that the higher second opening 513 is used for water inlet and the lower first opening 512 is used for water outlet.
[0080] In one illustrative embodiment, the anti-scaling bracket 51 is provided with a filling port 518 at one end of the anti-scaling bracket 51. The filling port 518 can be a circular opening. The filling port 518 is connected to the anti-scaling cavity 511 of the anti-scaling bracket 51.
[0081] The filter bracket 41 is detachably connected to the anti-scaling bracket 51. The filter bracket 41 and the anti-scaling bracket 51 can be detachably snap-connected, screw-connected or thread-connected. The filter bracket 41 blocks the filling port 518 of the anti-scaling bracket 51.
[0082] When the anti-scaling agent 52 in the anti-scaling bracket 51 needs to be replaced, the user can detach the filter bracket 41 from the anti-scaling bracket 51 to open the filling port 518 of the anti-scaling bracket 51, replace the anti-scaling agent 52 in the anti-scaling cavity 511 through the filling port 518, and then reattach the filter bracket 41 to the anti-scaling bracket 51. In this way, the user can conveniently replace the anti-scaling agent 52 by himself, and the user experience is better.
[0083] In one illustrative embodiment, the filter bracket 41 and the anti-scaling bracket 51 are detachably snap-connected. The filter bracket 41 is provided with a plurality of first snaps 414. The anti-scaling bracket 51 is provided with a plurality of first snap holes 519 at one end of the anti-scaling bracket 51. The first snap holes 519 are configured as through holes penetrating the side wall of the anti-scaling bracket 51. The number of the first snaps 414 and the first snap holes 519 can be both 2. The plurality of first snaps 414 hook the plurality of first snap holes 519, thereby connecting the filter bracket 41 and the anti-scaling bracket 51 together.
[0084] In this way, when assembling, only the filter bracket 41 and the anti-scaling bracket 51 need to be docked, so that the plurality of first snaps 414 hook the plurality of first snap holes 519, thereby assembling the filter bracket 41 and the anti-scaling bracket 51 together, improving the assembly speed. When disassembling, only the first snaps 414 need to be pushed out of the first snap holes 519 to detach the filter bracket 41 and the anti-scaling bracket 51.
[0085] In one illustrative embodiment, as shown in FIG. 6, the filter bracket 41 is provided with a plurality of second snaps 416. The anti-scaling bracket 51 is provided with a plurality of second snap holes 520 at one end of the anti-scaling bracket 51. The second snap holes 520 are configured as through holes penetrating the side wall of the anti-scaling bracket 51. The number of the second snaps 416 and the second snap holes 520 can be both 2. The plurality of second snaps 416 hook the plurality of second snap holes 520, thereby connecting the filter bracket 41 and the anti-scaling bracket 51 together. Figure 14As shown, the scale-inhibiting support 51 is further provided with a limiting groove 520 at one end thereof facing the filtering support 41, and the limiting groove 520 is located at one side of the charging port 518. The opening of the limiting groove 520 faces the filtering support 41. The filtering support 41 is provided with a limiting protrusion 413 on the sidewall thereof, and the limiting protrusion 413 protrudes radially outward from the surface of the filtering support 41. The limiting protrusion 413 of the filtering support 41 is accommodated in the limiting groove 520 of the scale-inhibiting support 51. The limiting groove 520 and the limiting protrusion 413 can be provided with two respectively, and the two limiting grooves 520 are located at opposite sides of the charging port 518 respectively, and the two limiting protrusions 413 are provided correspondingly with the two limiting grooves 520 respectively, and the two limiting protrusions 413 are accommodated in the two limiting grooves 520 respectively.
[0086] Since the limiting protrusion 413 of the filtering support 41 is accommodated in the limiting groove 520 of the scale-inhibiting support 51, the scale-inhibiting support 51 and the limiting protrusion 413 cannot rotate relative to each other, so that the buckling connection between the scale-inhibiting support 51 and the limiting protrusion 413 can be effectively avoided from being damaged.
[0087] In an exemplary embodiment, the scale-inhibiting support 51 and the filtering support 41 are both configured in a cylindrical shape. The scale-inhibiting support 51 and the filtering support 41 are coaxially arranged. The ends of the scale-inhibiting support 51 and the filtering support 41 close to each other are connected to each other.
[0088] The scale-inhibiting cavity 511 is configured in a substantially columnar cavity, and is coaxial with the scale-inhibiting support 51. The charging port 518 and the limiting groove 520 are both arranged at one end of the scale-inhibiting support 51 facing the filtering support 41, and the other end of the scale-inhibiting support 51 away from the filtering support 41 is closed.
[0089] The first opening 512 and the second opening 513 are both arranged on the sidewall of the scale-inhibiting support 51, and both penetrate the sidewall of the scale-inhibiting support 51.
[0090] The first opening 512 and the second opening 513 are different in position in the axial direction of the scale-inhibiting support 51.
[0091] The two ends of the filtering support 41 are both closed. One end of the filtering support 41 is inserted into the charging port 518 to block the charging port 518. The first buckling 414 and the limiting protrusion 413 are both arranged on the outer sidewall of the filtering support 41 inserted into the charging port 518. The filtering inlet 4111 and the filtering outlet 4112 are both arranged on the sidewall of the filtering support 41.
[0092] In this way, the scale-inhibiting support 51 and the filtering support 41 are both configured in a cylindrical shape, and the scale-inhibiting support 51 and the filtering support 41 are coaxially arranged, so that the filtering module 1a as a whole is in a straight strip shape, the structure is compact, the space occupied is small, and the filtering module 1a is convenient to insert into a chamber in a straight strip shape.
[0093] In an exemplary embodiment, as shown in FIG. 1, the filtering module 1a is provided with a plurality of filtering modules 1a arranged in parallel. Figure 12、 13 As shown in the figure, the filter inlets 4111 on the filter support 41 are provided in plurality. The filter inlets 4111 are provided in plurality, preferably two. The plurality of filter outlets 4112 are located at the end of the filter support 41 which is away from the scale inhibition support 51. The plurality of filter outlets 4112 can be uniformly distributed around the circumference of the filter support 41. The filter outlets 4112 are provided on the side of the plurality of filter inlets 4111 which is close to the scale inhibition support 51. A filter flow channel extends from each of the filter inlets 4111 to the filter outlets 4112;
[0094] The filter medium 42 is configured as a cylindrical filter screen. The filter medium 42 is provided in the filter flow channel and coaxially with the filter support 41. The filter medium 42 covers all the filter inlets 4111 on the filter support 41.
[0095] In this way, the filter medium 42 is inlaid in the filter support 41, and the filter medium 42 is not easy to come out of the filter support 41. At the same time, the filter support 41 is provided with a plurality of filter inlets 4111, and the cylindrical filter medium 42 covers all the filter inlets 4111, so that the filter medium 42 can be as large as possible in a limited space, and the resistance of the filter medium 42 to water flow is reduced.
[0096] In an illustrative embodiment, as shown in the figure, Figure 17 、 18 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 provided with the scale inhibition support 51. The closed end of the support body 411 is inserted into the charging port 518 of the scale inhibition support 51. The plurality of filter inlets 4111, the filter outlets 4112, the limiting protrusions 413 and the first buckles 414 are all provided on the side wall of the support body 411. The filter flow channel is provided in the support body 411. The plug 412 blocks the end of the support body 411 which is away from the scale inhibition support 51. The plug 412 and the support body 411 can be connected by buckling.
[0097] In an illustrative embodiment, the filter medium 42 and the filter support 41 are integrally formed. The surface of the filter support 41 is provided with a rubber coating layer, which connects the filter medium 42 to the filter support 41, so that the filter medium 42 and the filter support 41 are integrally formed.
[0098] The filter medium 42 and the filter support 41 are integrally formed, which can reduce the number of parts and the assembly steps.
[0099] In an illustrative embodiment, as shown in the figure, Figure 10 、 11As shown, the liquid adding assembly 100 further comprises a water inlet valve 3. A water inlet port 31 of the water inlet valve 3 is communicated with the filter outlet 4112 of the filter support 41, and a water outlet port 32 of the water inlet valve 3 is communicated with the first opening 512.
[0100] In this way, the filter outlet 4112 of the filter support 41 is connected to the first opening 512 of the scale inhibition support 51 through the water inlet valve 3. When the water inlet valve 3 is closed, the water path between the filter flow channel of the filter support 41 and the scale inhibition cavity 511 of the scale inhibition support 51 is cut off, and the second filter assembly 5 cannot discharge water through the second opening 513. When the water inlet valve 3 is opened, the water path between the filter flow channel of the filter support 41 and the scale inhibition cavity 511 of the scale inhibition support 51 is connected, and the second filter assembly 5 can discharge water through the second opening 513. Thus, the water inlet valve 3 can control the water inlet of the dilution water of the foam generator 200.
[0101] The second filter assembly 5 is arranged downstream of the water inlet valve 3. The water pressure of the water path downstream of the water inlet valve 3 is stable and low, which can ensure that the second filter assembly 5 will not burst due to unstable water pressure. The water inlet valve 3 is arranged downstream of the first filter assembly 4, which can avoid the water inlet valve 3 being blocked by impurities in the water.
[0102] In an illustrative embodiment, the mounting cylinder 11 is configured as a substantially cylindrical shape. The mounting cylinder 11 can be arranged vertically, and the first filter assembly 4 is arranged below the second filter assembly 5. The scale inhibition support 51 is detachably connected to the mounting cylinder 11. The scale inhibition support 51 is connected to the filter support 41.
[0103] The mounting cylinder 11 is sleeved on the scale inhibition support 51, which can prevent the scale inhibition support 51 from bursting due to water pressure. Since the scale inhibition support 51 is connected to the filter support 41 and detachably connected to the mounting cylinder 11, the first filter assembly 4 and the second filter assembly 5 can be inserted into or detached from the mounting cylinder 11 as a whole, which makes the first filter assembly 4 and the second filter assembly 5 more convenient to disassemble and assemble, and facilitates the cleaning of impurities on the filter medium 42 and the replacement of the scale inhibitor.
[0104] In an illustrative embodiment, the water inlet valve 3 is arranged outside the mounting cylinder 11 and fixed to one side of the mounting cylinder 11. The mounting cylinder 11 further comprises a first water outlet hole 114 and a first water inlet hole 115. The first water inlet port 111 is arranged at the end of the mounting cylinder 11 close to the first filter assembly 4. The first water outlet hole 114, the first water inlet hole 115, and the first water outlet port 113 are all arranged on the side wall of the mounting cylinder 11.
[0105] The first water inlet 111 on the mounting cylinder 11 is connected to the filter inlet 4111 on the filter support 41. The two ends of the first water outlet hole 114 on the mounting cylinder 11 are connected to the water inlet 31 of the water inlet valve 3 and the filter outlet 4112 of the filter support 41 respectively, and the water inlet 31 of the water inlet valve 3 is connected to the filter outlet 4112 through the first water outlet hole 114. The two ends of the first water inlet hole 115 on the mounting cylinder 11 are connected to the water outlet 32 of the water inlet valve 3 and the first opening 512 or the second opening 513 on the descaling support respectively. 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 mounting cylinder 11 is connected to the other one of the first opening 512 and the second opening 513.
[0106] In this way, the water inlet valve 3 is arranged outside the mounting cylinder 11 and fixed on one side of the mounting cylinder 11, which can make the entire liquid adding assembly 100 more compact. When the water inlet valve 3 is opened, water can flow through the first water inlet 111 of the mounting support 1, the filter inlet 4111 of the first filter assembly 4, the filter flow channel 4113, the filter 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 filter assembly 5, the descaling cavity 511, the other one of the first opening 512 and the second opening 513, and the first water outlet 113 of the mounting support 1 in sequence, and then output from the first water outlet 113 of the mounting support 1. When the water inlet valve 3 is closed, the first water outlet 113 stops water output.
[0107] The first water outlet 113 can be connected to the human body cleaning assembly and the foam generator 200 through a tee joint, and the first water outlet 113 delivers the purified water to the human body cleaning assembly and the foam generator 200 as human body cleaning water and foam liquid dilution water respectively. At the same time, the water output from the first water outlet 113 has been purified by the first filter assembly 4 and the second filter assembly 5 twice, and is more pure, which can ensure the health of the human body when used as human body cleaning water and prevent impurities from entering the foam generator 200 to cause damage when used as foam liquid dilution water.
[0108] In an exemplary embodiment, the outer peripheral wall of the descaling support 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 descaling support 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 connected to 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.
[0109] The installation cylinder 11 is sleeved on the scale inhibition support 51, and the inner circumferential wall of the installation cylinder 11 covers the opening of the first annular groove 514 and the opening of the second annular groove 515 of the scale inhibition support 51. The first water inlet hole 115 on the installation cylinder 11 is flush with the first annular groove 514 in the axial direction of the installation cylinder 11, and the inner end of the first water inlet hole 115 on the installation cylinder 11 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 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.
[0110] In this way, the first water inlet hole 115 on the installation cylinder 11 can be connected to the first opening 512 of the scale inhibition support 51 through the first annular groove 514, and the first water outlet 113 on the installation cylinder 11 can be connected to the second opening 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 first opening 512, and the first water outlet 113 does not need to be accurately aligned with the second opening 513, thereby reducing the matching precision requirement between the installation cylinder 11 and the scale inhibition support 51, and facilitating production and installation.
[0111] In an exemplary embodiment, as shown in Figure 13 The end of the scale inhibition support 51 away from the installation support 1 is provided with a handle 516 extending out of the installation cylinder 11. The handle 516 can be configured as a plate-shaped structure.
[0112] The user can operate the handle 516 to rotate the scale inhibition support 51, which facilitates disassembly and assembly of the scale inhibition support 51.
[0113] In an exemplary embodiment, as shown in Figure 11 The inner circumferential wall of the installation 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.
[0114] The scale inhibition support 51 and the installation cylinder 11 are threadedly connected through the cooperation of the internal thread 116 and the external thread 517. The scale inhibition support 51 only needs to be rotated relative to the installation cylinder 11 to achieve disassembly and assembly of the scale inhibition support 51, which facilitates disassembly and assembly of the scale inhibition support 51.
[0115] In an exemplary embodiment, as shown in Figure 11 The installation support 1 is further provided with a second water outlet 112. The installation support 1 is provided with a water channel connecting the first water inlet 111 and the second water outlet 112.
[0116] In an exemplary embodiment, the liquid adding assembly 100 further comprises a leakage prevention valve 7. The leakage prevention valve 7 is arranged at the first water inlet 111, and the filter support 41 is arranged between the leakage prevention valve 7 and the scale inhibitor, and the filter support 41 presses the leakage prevention valve 7. The leakage prevention valve 7 is configured to open the first water inlet 111 when pressed by the filter support 41, and to close the first water inlet 111 when not pressed by the filter support 41.
[0117] The leakage prevention valve 7 is opened when the first filter assembly 4 and the second filter assembly 5 are both installed in the mounting cylinder 11, and water can be input into the mounting cylinder 11 from the first water inlet 111. When the first filter assembly 4 and the second filter assembly 5 are removed from the mounting cylinder 11, the filter support 41 no longer presses the leakage prevention valve 7, and the leakage prevention valve 7 is closed, and water cannot be input into the mounting cylinder 11 from the first water inlet 111.
[0118] In this way, the user can remove the first filter assembly 4 and the second filter assembly 5 from the mounting cylinder 11 without closing the water source, and the leakage prevention valve 7 closes the first water inlet 111 after the first filter assembly 4 and the second filter assembly 5 are removed, and water cannot flow out of the mounting cylinder 11; and the leakage prevention valve 7 is pressed by the filter support 41 again after the first filter assembly 4 and the second filter assembly 5 are installed in the mounting cylinder 11 again, and the first water inlet 111 can input water again. In this way, the user can replace the scale inhibitor 52 more conveniently.
[0119] In an exemplary embodiment, as shown in FIG. 7, the leakage prevention valve 7 comprises a valve body 71, a sealing gasket 77, a closing member 75, and an elastic member 74. Figure 10 , 19 The valve body 71 comprises a valve seat 711, a connecting seat 712, and a connecting portion 713. The valve seat 711 is configured in a cylindrical shape. 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.
[0120] The connecting seat 712 is located on the side of the valve seat 711 away from the filter support 41. The connecting seat 712 can be configured in an annular shape. The connecting seat 712 can be coaxially arranged with the valve 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.
[0121] The connecting portion 713 can be configured in a strip shape. 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 in multiple, and the multiple connecting portions 713 are uniformly distributed in the circumferential direction of the connecting seat 712.
[0122] 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 inner passage of the sealing gasket 77 is communicated with the inner passage of the valve seat 711.
[0123] The closing member 75 includes a valve stem 751 and a valve disc 752. The valve stem 751 is configured as a straight rod. One end of the valve stem 751 is inserted into the slide channel of the connecting portion 713. The valve stem 751 is in clearance fit with the slide channel. The valve stem 751 can slide along the slide channel.
[0124] The valve disc 752 can be configured as a disc. The valve disc 752 is arranged between the sealing gasket 77 and the connecting seat 712. The valve disc 752 is connected to one end of the valve stem 751 close to the valve seat 711. The valve disc 752 can be coaxially arranged with the sealing gasket 77. The diameter of the valve disc 752 is greater than the diameter of the inner passage of the sealing gasket 77. The valve disc 752 can block one end of the inner passage of the sealing gasket 77 facing the valve disc 752.
[0125] The elastic member 74 can be a compression spring. One end of the elastic member 74 abuts against one end of the valve disc 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 disc 752. The elastic member 74 is in compression. The elastic member 74 applies an elastic force to the valve disc 752 towards the sealing gasket 77.
[0126] When the first filter assembly 4 and the second filter assembly 5 are installed in the cylinder, the filter support 41 presses the valve disc 752 to separate the valve disc 752 and the sealing gasket 77.
[0127] Thus, when the first filter assembly 4 and the second filter assembly 5 are installed in the cylinder, the filter support 41 presses the valve disc 752 to separate the valve disc 752 and the sealing gasket 77 of the leak-proof valve 7, the leak-proof valve 7 is opened, and water input into the installation cylinder 11 from the first water inlet 111 can flow through the gap between the valve seat 711 and the valve disc 752, the inner passage of the gasket, and the inner passage of the valve seat 711 in sequence to reach the second water outlet 112 and the filter inlet 4111 of the filter 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 and blocks the inner passage of the gasket, the leak-proof valve 7 is closed, and water cannot pass through the inner passage of the gasket to reach the second water outlet 112 and the filter inlet 4111 of the filter support 41.
[0128] In one illustrative embodiment, the water inlet valve 3 includes a waterway body 30. The waterway body 30 is provided with a water inlet 31, a water outlet 32, and a water flow passage 33 extending from the water inlet 31 to the water outlet 32.
[0129] As shown in Figure 21 The water inlet valve 3 comprises an electromagnetic valve 36, a flow restrictor 34 and a water inlet check valve 35. The electromagnetic valve 36, the flow restrictor 34 and the water inlet check valve 35 are arranged in sequence on the water flow channel 33.
