[0105] Embodiments of the present application, with reference to Figures 1 to 44 As shown in the drawings, a soft water valve applied to a soft water machine is provided, which is used to adjust the flow path change of the soft water machine to realize the switching of multiple function modes through the soft water valve.

[0106] With reference to Figures 1 to 4 and Figure 44 As shown in the drawings, embodiments of the present application provide a soft water valve, which includes a valve housing 110, a main valve assembly 120 and a secondary valve assembly 130, the valve housing 110 includes a main cavity 111 and a secondary cavity 112, by adjusting the on-off of the corresponding flow channel of the main valve assembly 120, adjusting the on-off of the corresponding flow channel of the secondary valve assembly 130, and cooperating with the main cavity 111 and the secondary cavity 112, the switching of multiple function modes can be realized.

[0107] Among them, the function modes switchable by the soft water valve include: water production mode, water injection mode, salt suction mode and cleaning mode, in the water production mode, raw water can be sent to the softening device 190 through the soft water valve, the soft water obtained by the softening device 190 is sent back to the soft water valve, and the user can take the soft water from the soft water outlet 114 of the soft water valve; in the water injection mode, water can be injected into the salt tank 200 through the salt tank connection port 1110 of the soft water valve, the water injected into the salt tank connection port 1110 can be raw water or soft water, so as to dissolve the salt in the salt tank; after the water is injected into the salt tank 200, the salt in the salt tank 200 can be dissolved for a period of time, this process can be called salt melting mode; in the salt suction mode, the salt water in the salt tank 200 is sent to the softening device 190 through the soft water valve, and the water cleaned through the softening device 190 is discharged through the soft water valve; in the cleaning mode, raw water is injected into the softening device 190 through the soft water valve, and the water cleaned through the softening device 190 is discharged through the soft water valve; the cleaning mode includes at least one of backwashing mode and forward washing mode, the backwashing mode can be understood as that the raw water is injected into the softening device 190 through the soft water inlet 119, and then discharged to the soft water valve through the raw water outlet 118; the forward washing mode can be understood as that the raw water is injected into the softening device 190 through the raw water outlet 118, and then discharged to the soft water valve through the soft water inlet 119.

[0108] It should be noted that the raw water can be understood as the water flowing into the raw water inlet 113 of the water softening valve, such as tap water, and the hardness of the raw water is greater than that of the soft water. The softening device 190 includes a resin tank, and the resin in the resin tank softens the raw water to obtain soft water. Of course, the softening device 190 can also be other structures that can be used to soften the raw water.

[0109] Reference Figure 13 As shown, the valve housing 110 includes a raw water inlet 113, a soft water outlet 114, a main cavity 111, a secondary cavity 112, a raw water outlet 118, and a soft water inlet 119. The raw water inlet 113 is used to connect with the raw water pipeline to make the raw water enter the valve housing 110 of the water softening valve. At least one of the main cavity 111 and the secondary cavity 112 can be communicated with the raw water inlet 113, that is, the raw water can flow into at least one of the main cavity 111 and the secondary cavity 112, and then the flow direction of the raw water is adjusted through the corresponding valve assembly. The raw water outlet 118 and the raw water inlet 113 can be adjusted by the main valve assembly 120. When the main valve assembly 120 communicates the raw water inlet 113 and the raw water outlet 118, the raw water can be conveyed to the softening device 190 through the raw water outlet 118. Based on the fact that the raw water outlet 118 and the soft water inlet 119 can be communicated through the softening device 190, the soft water in the softening device 190 can be conveyed to the water softening valve through the soft water inlet 119 after the raw water is softened in the softening device 190. The soft water inlet 119 is communicated with the soft water outlet 114 to send the soft water out of the water softening valve. Of course, the soft water inlet 119 can also be adjusted to be communicated or interrupted with the flow channel inside the secondary valve assembly 130 to adjust the flow direction of the soft water.

[0110] Among them, the raw water inlet 113 and the main cavity 111 can be provided with a raw water channel, and the main cavity inlet 116 is arranged between the raw water channel and the main cavity 111 to make the raw water in the raw water channel enter the main cavity 111 through the main cavity inlet 116. The soft water outlet 114 and the soft water inlet 119 can be provided with a soft water channel to make the soft water conveyed to the soft water outlet 114 through the softening channel, which is convenient for the installation of the water softening valve and other pipelines and components.

[0111] The main valve assembly 120 includes a main valve core and a main driving part for driving the main valve core to move, and the main valve core is located in the main cavity 111; the main valve assembly 120 is used for regulating the on-off of the main cavity 111 and the raw water outlet 118, that is, regulating the on-off of the main cavity 111 and the softening device 190, when the main valve assembly 120 connects the main cavity 111 and the raw water outlet 118, it can be used for water supply to the softening device 190; the auxiliary valve assembly 130 includes an auxiliary valve core and an auxiliary driving part for driving the auxiliary valve core to move, and the auxiliary valve core is located in the auxiliary cavity 112; the auxiliary valve core regulates the on-off of the flow channel, and can adjust the on-off of the soft water inlet 119 and the corresponding passage in the auxiliary valve core, and can also adjust the on-off of the auxiliary cavity 112 and the corresponding passage, such as the on-off of the auxiliary cavity 112 and the salt tank connecting port 1110, the on-off of the soft water inlet 119 and the jet device, and the on-off of the auxiliary cavity 112 and the salt tank connecting port 1110, etc., the auxiliary cavity 112 and the auxiliary valve assembly 130 are mainly used to realize the regeneration of the softening material in the softening device 190 (the regeneration process includes: water injection mode, salt suction mode and cleaning mode). Therefore, the main driving part can drive the main valve core to move, and the auxiliary driving part can drive the auxiliary valve core to move, so as to switch the water softening valve between the water making mode, the water injection mode, the salt suction mode and the cleaning mode.

[0112] The main cavity 111 and the main valve assembly 120 are mainly used for water supply to the softening device 190, and the functions of the main cavity 111 and the main valve assembly 120 are mainly for normal water making, and because the normal water making flow is relatively large, the large opening structure of the main cavity 111 and the main valve core is used for water making, at this time, the auxiliary cavity 112 and the flow channels of the auxiliary valve core do not participate in the work. Because the water softener also has other state functions, such as forward washing, reverse washing, water injection, salt suction slow washing, etc., the flow requirements of these states are relatively small, so the opening area in the auxiliary valve core is small, therefore, these states are mainly controlled by the auxiliary cavity 112 and the auxiliary valve assembly 130. The auxiliary cavity 112 and the auxiliary valve assembly 130 are mainly used for regulating other flow paths, and the main cavity 111 and the main valve assembly 120 can increase the water flow to the softening device 190, and the auxiliary cavity 112 and the main cavity 111 cooperate to perform other functions.

[0113] The main cavity 111 cooperates with the main valve assembly 120 to mainly form a water production flow channel 124, which is connected with the main cavity 111 and the raw water outlet 118, and the water production flow channel 124 is used for water production by using the large opening structure of the main valve core. At this time, the flow channels formed by the auxiliary cavity 112 and the auxiliary valve assembly 130 do not participate in work. Since the water softener also has other state functions, such as cleaning, water injection, salt suction slow washing and the like, the flow demand of the raw water in these states is relatively small, so the auxiliary valve core can form multiple flow channels, and the flow area required by the flow channels formed by the auxiliary valve core is relatively small. These states are mainly controlled by the auxiliary cavity 112 and the auxiliary valve assembly 130, and the main cavity 111 cooperates with the main valve assembly 120 to discharge sewage during the regeneration process. In some cases, the main cavity 111 and the auxiliary cavity 112 have the same shape, the main valve assembly 120 and the auxiliary valve assembly 130 have the same size of the outer contour, and the flow area of the flow channels formed by the auxiliary cavity 112 and the auxiliary valve assembly 130 is smaller than the flow area of the water production flow channel 124 formed by the main cavity 111 and the main valve assembly 120.

[0114] It can be understood that at least one of the main cavity 111 and the auxiliary cavity 112 is connected with the raw water inlet 113, that is, the raw water is sent into the softening device 190 through at least one of the main cavity 111 and the auxiliary cavity 112. In this case, at least one of the main cavity 111 and the auxiliary cavity 112 can be connected with the raw water inlet 113 through a channel, that is, a raw water channel can be arranged between the main cavity 111 and the raw water inlet 113, and / or a channel can be arranged between the auxiliary cavity 112 and the raw water inlet 113. Of course, when the main cavity 111 and the auxiliary cavity 112 are both connected with the raw water inlet 113, the main cavity 111 and the auxiliary cavity 112 can be connected with the raw water inlet 113 through independent channels. Alternatively, one of the main cavity 111 and the auxiliary cavity 112 is connected with the raw water inlet 113 through a channel, and the main cavity 111 and the auxiliary cavity 112 are connected through a communication channel 1111 (see FIG. 11). Figure 40

[0115] The soft water valve of the embodiment of the present application has a multifunctional two-cavity structure design, which can meet the use requirements of different states of the water softener. By switching the water paths of the main valve assembly 120 and the auxiliary valve assembly 130, the water path adjustment of different states of the water softener is realized, that is, the water path function requirements of multiple states such as the water production mode, the cleaning mode (at least one of the forward washing and the reverse washing), the water injection mode, the salt suction slow washing mode (hereinafter referred to as the salt suction mode) and the like are realized. The whole valve head structure is compact, simple, has high reliability, and is stable and good in work.

[0116] ​The valve housing 110 of the water softener valve is further provided with a blow-off port 115 and a salt tank connecting port 1110. The blow-off port 115 is used for discharging sewage, and can be connected to the flow channel of at least one of the main valve assembly 120 and the auxiliary valve assembly 130 to realize blow-off of different flow paths. The salt tank connecting port 1110 is used for connecting with the salt tank 200, and can inject water into the salt tank 200. The salt tank connecting port 1110 can also guide brine from the salt tank 200 into the water softener valve. The salt tank connecting port 1110 can have at least one of the functions of water injection and brine suction. One of the main valve assembly 120 and the auxiliary valve assembly 130 can be used to adjust the salt tank connecting port 1110 to enable or disable the water softener valve and the salt tank 200.

[0117] In some cases, as shown in Figure 5 and Figure 6 At least one of the main valve assembly 120 and the auxiliary valve assembly 130 is a multi-position multi-way valve. Both the main valve assembly 120 and the auxiliary valve assembly 130 can switch between multiple positions to realize on-off adjustment of multiple flow paths.

[0118] For example, the main valve assembly 120 can switch between two main valve positions. In one main valve position, the main valve assembly 120 connects the main cavity 111 with the raw water outlet 118 to supply water to the softening device 190. In another main valve position, the main valve assembly 120 connects the raw water outlet 118 with the blow-off port 115 to realize blow-off. The auxiliary valve assembly 130 can switch between multiple auxiliary valve positions (such as three, four, five, etc.). One auxiliary valve position corresponds to one mode of the water softener valve. The main valve assembly 120 can also switch between three main valve positions (not shown in the figure). In one main valve position, the main valve assembly connects the main cavity with the raw water outlet to supply water. In the other two main valve positions, the main valve assembly can switch between water injection mode and brine suction mode. The auxiliary valve assembly can also switch between three auxiliary valve positions (not shown in the figure). The auxiliary valve positions are mainly used for cleaning and cooperating with the water injection mode and the brine suction mode. The structures of the main valve assembly and the auxiliary valve assembly can be various, and the functions and structures of the main valve assembly and the auxiliary valve assembly can be set as needed.

[0119] In some cases, as shown in Figure 5 and Figure 6 The main drive part of the main valve assembly 120 is used to drive the main valve core to rotate, and the main valve core switches between multiple main valve positions by rotating. And / or, the auxiliary drive part of the auxiliary valve assembly 130 is used to drive the auxiliary valve core to rotate, and the auxiliary valve core switches between multiple auxiliary valve positions by rotating.

[0120] As shown in Figure 7As shown, when the main valve assembly 120 is a disc valve, the main valve core includes a main stationary valve disc 122 and a driving valve disc 121. The main stationary valve disc 122 is fixed in the main cavity 111. The main drive unit is connected to the driving valve disc 121, and the main drive unit is used to drive the driving valve disc 121 to rotate relative to the main stationary valve disc 122, so as to adjust the flow path of the corresponding main valve assembly 120. And / or, refer to Figure 8 As shown, when the secondary valve assembly 130 is a disc valve, the secondary valve core includes a secondary stationary valve plate 132 and a secondary moving valve plate 131. The secondary stationary valve plate 132 is fixed in the secondary cavity 112, and the secondary drive unit is connected to the secondary moving valve plate 131. The secondary drive unit is used to drive the secondary moving valve plate 131 to rotate relative to the secondary stationary valve plate 132, so as to adjust the flow channel opening and closing of the secondary valve assembly 130.

[0121] Among them, reference Figures 5 to 8 As shown, at least one of the main valve assembly 120 and the auxiliary valve assembly 130 is a disc valve. Disc valves have a simple structure; both the valve discs of the main valve core and the auxiliary valve core can be made of ceramic. When the valve disc is made of ceramic, its lifespan and reliability are higher due to the good wear resistance of ceramic. Compared to plunger valves, which require higher precision in structural machining, disc valves have lower manufacturing costs, making them an important direction for the development of soft water valves.

[0122] Of course, in some cases, the main valve assembly 120 and the auxiliary valve assembly 130 can also switch the flow path on and off in other ways, such as switching the flow path by moving one of the main valve assembly and the auxiliary valve assembly, and one of the main valve assembly and the auxiliary valve assembly can be a plunger valve.

[0123] Below, for reference Figures 1 to 29 As shown, in the case of a soft water valve including a valve body 110, a main valve assembly 120 and a secondary valve assembly 130, the main valve assembly 120 and the secondary valve assembly 130 cooperate to achieve switching of multiple modes, which will be explained below.

[0124] Regarding water production mode:

[0125] refer to Figures 2 to 4 , Figures 14 to 16 As shown, in the water production mode, the main valve core's water production channel 124 is connected, which in turn connects the main chamber 111 to the raw water outlet 118. The main chamber 111 is connected to the raw water inlet 113, and the soft water inlet 119 is connected to the soft water outlet 114. This allows water to flow along the path of the raw water inlet 113, the main chamber 111, the water production channel 124, the raw water outlet 118, the soft water inlet 119, and the soft water outlet 114. The main chamber 111 and the main valve assembly 120 are mainly used to supply water to the softening device 190 in the water production mode. This helps to increase the flow rate of water supplied by the soft water valve to the softening device 190, thereby increasing the flow rate of soft water produced by the softening device 190, making it easier for users to access soft water.

[0126] In the water production mode, the main cavity 111 cooperates with the main valve assembly 120 to supply water to the softening device 190, and the softened water obtained by the softening device 190 can be discharged through the softened water inlet 119 and the softened water outlet 114. During this process, the auxiliary cavity 112 and the auxiliary valve assembly 130 do not participate in the water delivery in the water production mode. The auxiliary valve assembly 130 can block the auxiliary cavity 112 and the softened water inlet 119 to prevent the water in the softened water inlet 119 from entering the auxiliary cavity 112, so as to ensure that the softened water is discharged from the softened water outlet 114, and the user can take water conveniently.

[0127] The main driving part is used to drive the main valve core to move, so that the main valve core is switched to the water production flow channel 124. It can be understood that the water production flow channel 124 can be connected in some modes and disconnected in some modes.

[0128] It can be understood that, as shown in Figure 15 The main valve core includes a main static valve plate 122 and a main dynamic valve plate 121. The main dynamic valve plate 121 is connected to the main driving part, and the main static valve plate 122 is fixed to the valve shell 110. The main static valve plate 122 is fixed in the main cavity 111, and the main static valve plate 122 is configured with a water passing hole 1221. The main dynamic valve plate 121 is configured with a main valve water inlet 1211, which is in communication with the main cavity 111. The water passing hole 1221 and the main valve water inlet 1211 are in communication to form the water production flow channel 124. The main driving part drives the main dynamic valve plate 121 to adjust the position relative to the main static valve plate 122, so as to adjust the connection and disconnection of the main cavity 111 and the raw water outlet 118. The structure is simple and the adjustment is simple.

[0129] Corresponding to the water passing hole 1221 of the main static valve plate 122, the valve shell 110 is provided with a water inlet hole 1126 for connecting the main cavity 111 and the raw water outlet 118. The water inlet hole 1126 is in communication with the water passing hole 1221. By moving the main dynamic valve plate 121, the water passing hole 1221 can be closed, so that the water passing hole 1221 is disconnected with the main valve water inlet 1211, and the raw water of the raw water inlet 113 cannot be delivered to the softening device 190 through the main cavity 111 and the main valve assembly 120. By moving the main dynamic valve plate 121, the water passing hole 1221 can be opened, so that the water passing hole 1221 is in communication with the main valve water inlet 1211. The main valve water inlet 1211 is in communication with the raw water inlet 113 through the main cavity 111, so that the raw water is sent to the softening device 190 through the main cavity 111, the main valve water inlet 1211, the water passing hole 1221, the water inlet hole 1126 and the raw water outlet 118.

[0130] When the main drive unit drives the active valve plate 121 to rotate, the active valve plate 121 can rotate to connect or disconnect the main valve inlet 1211 from the water passage hole 1221. The water passage hole 1221 and the water inlet hole 1126 can be fan-shaped holes, and the main valve inlet 1211 can be formed through the fan-shaped notch of the active valve plate 121 to ensure the flow area of ​​the raw water. The main valve inlet 1211 can correspond to the main cavity inlet 116, that is, the water in the raw water channel enters the main cavity 111 and the water production channel 124 through the main cavity inlet 116, reducing the flow resistance of the raw water in the main cavity 111 and the main valve assembly 120.

[0131] In some cases, refer to Figure 5 As shown, the main drive unit includes a main valve motor 123 and a main shaft assembly 126. One end of the main shaft assembly 126 is connected to the main valve motor 123, and the other end is connected to the active valve plate 121. The active valve plate 121 includes a valve plate body and a blocking part 1214. In the water production mode, the blocking part 1214 is located between the main shaft assembly 126 and the water passage hole 1221. The blocking part 1214 and the main stationary valve plate 122 form a main valve inlet 1211. The orthographic projection area of ​​the blocking part 1214 on the main stationary valve plate 122 is smaller than the flow area of ​​the water passage hole 1221. The blocking part 1214 does not affect the water flow effect of the water passage hole 1221. The projection area of ​​the valve plate body and the blocking part 1214 on the end face of the main shaft assembly 126 covers the end face area of ​​the main shaft assembly 126. The setting of the blocking part 1214 can reduce the impact of water on the main shaft assembly 126. The first side of the shielding part 1214 is connected to the valve plate body by an arc-shaped surface. The first side is the side facing the main stationary valve plate 122. The second side of the shielding part 1214 is attached to the main shaft assembly 126. The first side and the second side are opposite sides.

[0132] The thickness of the shielding part 1214 is less than or equal to the thickness of the valve plate body. This can be understood as the thickness of the shielding part 1214 being less than or equal to the minimum thickness of the valve plate body, in order to ensure the space within the main cavity 111.

[0133] When a main chamber inlet 116 is provided between the raw water channel and the main chamber 111, and the main chamber inlet 116 corresponds to the main valve inlet 1211, the raw water can enter between the shielding part 1214 and the main static valve plate 122 through the main chamber inlet 116. The shielding part 1214 can guide the water flow and reduce the flow resistance of the raw water.

[0134] The auxiliary valve assembly includes an auxiliary moving valve plate and an auxiliary stationary valve plate. In the first auxiliary valve position, the orifices of the auxiliary moving valve plate are all closed by the grooves of the auxiliary stationary valve plate.

[0135] The above content describes the main valve assembly 120, the main chamber 111, and the valve housing 110 in the water production mode.

[0136] The water production mode is the main function mode of the soft water valve. The other function modes (water injection mode, salt suction mode, and cleaning mode) of the soft water valve are mainly to ensure the softening effect of the softening device 190 and regenerate the softening material in the softening device 190 to continuously provide soft water. Among them, the water injection mode is mainly to inject water into the salt tank 200 to melt the salt in the salt tank 200 and regenerate the softening material in the softening device 190.

[0137] Regarding the water injection mode:

[0138] Reference Figures 2 to 12 And Figures 17 to 19 It can be understood that the valve housing 110 is provided with a salt tank connecting port 1110 for connecting the salt tank 200. In the water injection mode, the water injection flow channel 134 of the secondary valve core is communicated, and the water injection flow channel 134 communicates the soft water inlet 119 and the salt tank connecting port 1110, so that water flows along the path of the soft water inlet 119, the water injection flow channel 134 and the salt tank connecting port 1110. By adjusting the state of the secondary valve assembly 130, the softening device 190 is communicated with the salt tank 200, and the soft water after the softening of the softening device 190 is delivered to the salt tank 200, so that the salt in the salt tank 200 is dissolved to pass the salt solution into the softening device 190.

[0139] Among them, in the water injection mode, the way of water inlet 113 to the softening device 190, that is, the water inlet 113 and the raw water outlet 118 can be communicated through the cooperation of the main cavity 111 and the main valve assembly 120, which is helpful to simplify the structure of the main cavity 111 and the main valve assembly 120.

[0140] In the case that the main valve core is provided with the water production flow channel 124, the water production flow channel 124 communicates the main cavity 111 and the raw water outlet 118, which can be referred to the above description about the water production mode, and reference Figure 18 It is not repeated here. It can be understood that the difference between the water injection mode and the water production mode is that the state of the secondary valve assembly 130 is different. The soft water valve switches between the water injection mode and the water production mode, and the main valve core is located at the first main valve position. By switching the position of the secondary valve core, the switching of the two modes can be realized. In the water production mode, the position of the secondary valve core can be understood as the first secondary valve position, and in the water injection mode, the position of the secondary valve core can be understood as the fourth secondary valve position. By driving the secondary valve core to rotate through the secondary driving part, the secondary valve core is switched between the first secondary valve position and the fourth secondary valve position, that is, the secondary driving part is used to drive the secondary valve core to rotate to connect or disconnect the water injection flow channel 134. The structure of the secondary valve assembly 130 is simple and easy to operate.

[0141] It can be understood that the auxiliary valve core includes an auxiliary static valve plate 132 and an auxiliary dynamic valve plate 131, the auxiliary dynamic valve plate 131 is connected to the auxiliary driving part, the auxiliary static valve plate 132 is fixed with the valve shell 110, the auxiliary dynamic valve plate 131 is configured with an auxiliary valve first groove body 1311, the auxiliary static valve plate 132 is configured with a salt injection water hole 1324 and a softening connection hole 1322, the salt injection water hole 1324 is communicated with the salt tank connecting port 1110, the softening connection hole 1322 is communicated with the soft water inlet 119, and the auxiliary valve first groove body 1311 is communicated with the salt injection water hole 1324 and the softening connection hole 1322 to form a water injection flow channel 134. The auxiliary static valve plate 132 cooperates with the auxiliary dynamic valve plate 131 to communicate the softening device 190 with the salt tank 200, and the soft water in the softening device 190 is smoothly sent into the salt tank 200, and the structure is simple.

[0142] The auxiliary driving part is used for driving the auxiliary dynamic valve plate 131 to rotate relative to the auxiliary static valve plate 132, so that the auxiliary valve first groove body 1311 of the auxiliary dynamic valve plate 131 moves to a position of communicating the softening connection hole 1322 with the salt injection water hole 1324.

[0143] Reference Figure 19 As shown, the auxiliary valve first groove body 1311 is an arc-shaped groove extending along the circumference of the auxiliary dynamic valve plate 131, in the water injection mode, the auxiliary valve first groove body 1311 covers the softening connection hole 1322 and the salt injection water hole 1324 in the orthographic projection of the auxiliary static valve plate 132, ensuring that the entire area of the softening connection hole 1322 and the salt injection water hole 1324 is communicated with the auxiliary valve first groove body 1311, avoiding leakage and ensuring water flow effect. The flow area of the softening connection hole 1322 and the salt injection water hole 1324 is smaller than the flow area of the auxiliary valve first groove body 1311, and the sum of the flow areas of the softening connection hole 1322 and the salt injection water hole 1324 is also smaller than the flow area of the auxiliary valve first groove body 1311.

[0144] The valve shell 110 is provided with a softening connection port 1121 and a salt injection water port 1119, the softening connection port 1121 corresponds to and is communicated with the softening connection hole 1322, and the salt injection water port 1119 corresponds to and is communicated with the salt injection water hole 1324. The auxiliary static valve plate 132 and the valve shell 110 are provided with an auxiliary valve sealing piece 1392, the auxiliary valve sealing piece 1392 is sealingly connected between the softening connection port 1121 and the softening connection hole 1322, and the auxiliary valve sealing piece 1392 is also sealingly connected between the salt injection water port 1119 and the salt injection water hole 1324, to ensure independent sealing between the holes.

[0145] When the soft water valve includes the jet 160, the salt water injection hole 1324 is communicated with the salt tank connecting port 1110 through the jet 160, that is, the water injection flow channel 134 is communicated with the salt tank connecting port 1110 through the jet 160; by switching the state of the auxiliary valve core, the soft water valve can also suck the salt solution from the salt tank 200 through the jet 160 and send it into the softening device 190, that is, in the water injection mode and the salt suction mode, the flow path of water between the softening device 190, the jet 160 and the salt tank 200 is opposite; in the water injection mode, water flows from the softening device 190 to the jet 160 through the auxiliary valve assembly 130, and then flows into the salt tank connecting port 1110 through the jet 160; in the salt suction mode, the salt solution in the salt tank 200 enters the jet 160, and then the mixed solution in the jet 160 is sent into the softening device 190 through the auxiliary valve assembly 130; it should be noted that the flow channels in the auxiliary valve assembly 130 are different in the water injection mode and the salt suction mode. Of course, in the water injection mode, the water flowing through the water injection flow channel 134 of the auxiliary valve assembly 130 to the salt tank connecting port 1110 can also flow directly into the salt tank connecting port 1110 without passing through the jet 160, at this time, the salt water injection hole 1324 can be directly communicated with the salt tank connecting port 1110.

[0146] In the above embodiment, the path of the raw water inlet 113 to the auxiliary valve assembly 130 is the same as the water making mode, that is, the soft water valve controls the softening device 190 to deliver soft water to the salt tank connecting port 1110, but the water injection mode can also introduce raw water into the salt tank connecting port 1110 through other ways. In some cases, in the water injection mode, the main cavity 111 and the main valve assembly 120 can not work, by adjusting the state of the auxiliary valve assembly 130, in the case that the raw water inlet 113 is communicated with the auxiliary cavity 112, the auxiliary valve assembly 130 is adjusted to make the auxiliary cavity 112 communicated with the salt tank connecting port 1110, and the raw water is introduced into the salt tank 200 through the salt tank connecting port 1110 (not shown in the figure), so that the salt in the salt tank 200 is dissolved to make brine into the softening device 190. For example, the main cavity 111 of the valve housing 110 is communicated with the auxiliary cavity 112, the water injection channel is communicated with the auxiliary cavity 112 and the salt tank connecting port 1110, the raw water in the auxiliary cavity 112 can be sent into the salt tank 200, and brine can also be obtained by dissolving in the salt tank 200, at this time, the auxiliary valve inlet 1314 of the auxiliary valve piece 131 is communicated with the salt water injection hole 1324, and the raw water in the auxiliary cavity 112 flows along the auxiliary valve inlet 1314, the salt water injection hole 1324 and the salt tank connecting port 1110, at this time, the main valve assembly 120 can disconnect or communicate the main cavity 111 with the raw water outlet 118, when the main valve assembly 120 communicates the main cavity 111 with the raw water inlet 113, the soft water valve can execute the water making mode and the water injection mode at the same time, and the water injection mode does not affect the user to take soft water.

[0147] The above describes the water injection mode. After the water injection in the salt tank 200 is completed, the salt in the salt tank 200 is dissolved for a preset time, which can be 1 hour, 2 hours, etc. This process can be understood as the salt tank 200 entering a salt melting state. During the process in the salt melting state, the water production mode can be executed, so that the user can obtain soft water from the soft water outlet 114. After the salt in the salt tank 200 is dissolved, the brine is sent into the softening device 190, that is, the salt absorption mode is executed. The salt absorption mode is described below.

[0148] Salt absorption mode:

[0149] Referring to Figures 1 to 12 and Figures 20 to 22 It can be understood that the valve housing 110 is connected with the jet device 160, the valve housing 110 is provided with a salt tank connecting port 1110, the salt solution in the salt tank connecting port 1110 is sucked into the salt tank connecting port 1110 through the jet device 160, and the salt solution is sent into the softening device 190 through cooperation of the jet device 160 and the auxiliary valve assembly 130, and then the sewage after regeneration of the softening material in the softening device 190 is discharged.

[0150] In the salt absorption mode, referring to Figures 35 to 38 The jet device 160 is provided with a jet channel. The jet inlet 161 of the jet channel is communicated with the auxiliary cavity 112 through the auxiliary valve core, the suction inlet 163 of the jet channel is communicated with the salt tank connecting port 1110, and the jet outlet 162 of the jet channel is communicated with the softening device 190 through the auxiliary valve core, so that the raw water of the raw water inlet 113 and the brine of the salt tank connecting port 1110 are mixed in the jet channel to obtain a mixed liquid, and the mixed liquid is introduced into the softening device 190. The suction inlet 163 is located on the flow path between the jet inlet 161 and the jet outlet 162. The raw water flows from the jet inlet 161 to the jet outlet 162. The raw water flows in the jet channel, so that a negative pressure is generated at the suction inlet 163. Under the action of the negative pressure, the salt solution in the salt tank 200 is sucked into the jet inlet and the jet channel along the salt tank connecting port 1110 and the suction inlet 163, so that the salt solution is mixed with the raw water in the jet channel to obtain a mixed solution. The mixed solution flows to the softening device 190 along the jet outlet 162, and the process of sending the mixed solution into the softening device 190 is completed.

[0151] In some cases, the raw water of the jet inlet 161 is the raw water in the auxiliary cavity 112 through the auxiliary valve assembly 130. The auxiliary cavity 112 is communicated with the raw water inlet 113 through the main cavity 111 (or the auxiliary cavity is directly communicated with the raw water inlet), and the auxiliary cavity 112 and the main cavity 111 are always filled with raw water. Of course, the jet inlet 161 is not limited to being communicated with the raw water inlet 113 through the auxiliary cavity 112. For example, the jet inlet 161 can also be directly communicated with the raw water inlet 113 (not shown in the figure), which can simplify the structure of the auxiliary valve assembly 130.

[0152] In some cases, the mixed solution of the jet flow outlet 162 is drained to the soft water inlet 119 through the auxiliary valve assembly 130, so that the mixed solution flows into the softening device 190 along the soft water inlet 119, the mixed solution washes the softening material in the softening device 190, and the cleaned sewage is drained to the sewage outlet 115 along the raw water outlet 118, so that the sewage discharge is completed. Of course, the mixed solution of the jet flow outlet 162 is not limited to being drained to the soft water inlet 119, but can also be drained to the raw water outlet 118 through the cooperation of the auxiliary valve assembly 130 and the main valve assembly 120, so that the mixed solution flows into the softening device 190 along the raw water outlet 118, the mixed solution washes the softening material in the softening device 190, and the cleaned sewage is drained to the sewage outlet 115 through the auxiliary valve assembly 130. The path of the mixed solution into the softening device 190 and the sewage out of the softening device 190 is various, and can be selected as needed.

[0153] In the case that the raw water in the auxiliary cavity 112 is introduced into the jet flow inlet 161 through the auxiliary valve assembly 130, the mixed solution of the jet flow outlet 162 is introduced into the soft water inlet 119 through the auxiliary valve assembly 130, and the sewage of the raw water outlet 118 is discharged to the sewage outlet 115 through the main valve assembly 120, the first salt suction channel 135 of the auxiliary valve core and the second salt suction channel 136 are communicated, the first salt suction channel 135 communicates the auxiliary cavity 112 and the jet flow inlet 161, and the second salt suction channel 136 communicates the jet flow outlet 162 and the soft water inlet 119. The first sewage discharge channel 125 of the main valve core communicates the raw water outlet 118 and the sewage passage 1115 (the end of the sewage passage 1115 forms the sewage outlet 115) of the valve shell 110, the raw water in the auxiliary cavity 112 enters the jet flow inlet 161 along the first salt suction channel 135, the raw water and the salt solution are mixed in the jet flow passage to obtain a mixed liquid, and the mixed liquid flows out along the jet flow outlet 162, the soft water inlet 119, the raw water outlet 118, the first sewage discharge channel 125 and the sewage outlet 115, so that the softening device 190 is slowly washed by salt.

[0154] In some cases, the valve shell 110 is provided with a filter passage 1118, and a filter 180 is arranged in the filter passage 1118. The filter passage 1118 communicates the jet flow inlet 161 and the first salt suction channel 135, so that the raw water flowing out of the first salt suction channel 135 is filtered through the filter passage 1118 before being introduced into the softening device 190 along the jet flow passage and the second salt suction channel 136. The filtered raw water is used for regeneration of the softening material.

[0155] The filter 180 can be a filter screen, a filter core, a filter membrane or the like, and the structure of the filter 180 is various. The filter 180 can be fixed in the filter passage 1118, and the filter 180 can be fixed by clamping, fastening, screwing or the like, and the fixing mode of the filter 180 is various and can be selected as needed. The filter 180 can be detachably connected to the filter passage 1118, so that the filter 180 can be replaced conveniently.

[0156] The valve housing 110 is provided with a mounting channel 117, and the fluidic device 160 is detachably mounted in the mounting channel 117, facilitating the dismounting of the fluidic device 160. In some cases, as shown in Figure 35 and Figure 40 The valve housing 110 is integrally formed with the mounting channel 117, facilitating the processing of the valve housing 110 and simplifying the structure of the water softener. Alternatively, the valve housing 110 is directly connected with the fluidic device 160 (not shown in the figure), and the fluidic device 160 does not need to be mounted in the channel, and the fluidic device 160 is more independent. When the valve housing 110 is provided with a filter channel 1118, the filter channel 1118 can also be formed by a structure independent of the valve housing 110, such as a pipe detachably connected to the valve housing 110. The pipe can be connected to the independent fluidic device 160, reducing the number of parts. Based on the foregoing, the mounting modes of the fluidic device 160 and the filter 180 in the valve housing 110 are various, and can be selected as needed, which will not be listed one by one here.

[0157] It should be noted that, as shown in Figures 35 to 38 The fluidic device 160 can be a Venturi structure, and the fluidic device 160 is arranged on the left side of the valve housing 110. Two channels are opened on the left side of the valve housing 110, the lowermost channel is the filter channel 1118 for mounting the filter 180, which is used for filtering impurities to prevent the fluidic device 160 from being blocked, and the upper channel is the mounting channel 117 for mounting the fluidic device 160. The side of the fluidic device 160 is provided with a salt tank connecting port 1110 perpendicular to the water flow direction of the pipe. The salt tank connecting port 1110 can be connected with the salt tank connecting port 1110 through a hose, and the salt tank connecting port 1110 is used for salt absorption during regeneration.

[0158] As shown in Figures 35 to 38 The fluidic device 160 is provided with a first flow channel 164 and a second flow channel 165. One end of the first flow channel 164 is communicated with the suction port 163, and the other end of the first flow channel 164 forms the jet inlet 161. One end of the second flow channel 165 is communicated with the suction port 163, and the other end of the second flow channel 165 forms the jet outlet 162. The end of the first flow channel 164 is provided with a jet flow limiting member 166 to adjust the flow of the fluidic device 160.

[0159] Next, the structure of the sub-valve core forming the first salt suction flow channel 135 and the second salt suction flow channel 136 will be described.

[0160] It can be understood that, as shown in Figure 22As shown, the sub-valve core includes a sub-static valve piece 132 and a sub-moving valve piece 131, the sub-moving valve piece 131 is connected to the sub-driving part, the sub-static valve piece 132 is fixed with the valve shell 110, the sub-static valve piece 132 is located in the sub-cavity 112, the sub-static valve piece 132 is configured with a softened connection hole 1322, a brine outlet 1323 and a salt suction and water injection hole 1324, the sub-moving valve piece 131 is configured with a sub-valve third groove body 1313 and a sub-valve water inlet 1314, the sub-valve water inlet 1314 communicates the salt suction and water injection hole 1324 to form a first salt suction flow channel 135, the sub-valve water inlet 1314 communicates with the raw water inlet 113 through the sub-cavity 112, the salt suction and water injection hole 1324 communicates with the jet flow inlet 161, the brine outlet 1323 communicates with the softened connection hole 1322 through the sub-valve third groove body 1313 to form a second salt suction flow channel 136, the brine outlet 1323 communicates with the jet flow outlet 162, and the softened connection hole 1322 communicates with the soft water inlet 119. In the salt suction mode, the raw water flows along the path of the sub-valve water inlet 1314, the salt suction and water injection hole 1324, the jet flow inlet 161 and the jet flow outlet 162, after the raw water enters the jet flow inlet 161, under the negative pressure of the raw water, the salt solution in the salt tank 200 enters the suction inlet 163 through the salt tank connecting port 1110, so that the salt solution and the raw water are mixed in the jet flow channel to obtain a mixed solution, the mixed solution flows along the path of the jet flow outlet 162, the brine outlet 1323, the sub-valve third groove body 1313 and the softened connection hole 1322, and the mixed solution enters the softening device 190 through the softened connection hole 1322, and the salt solution is transported according to the above path.

[0161] Wherein, the raw water of the sub-valve water inlet 1314 comes from the sub-cavity 112, and the raw water in the sub-cavity 112 comes from the raw water inlet 113.

[0162] In some cases, referring to Figure 40 As shown, the valve shell 110 includes a communication channel 1111, the communication channel 1111 communicates the main cavity 111 with the sub-cavity 112, the raw water inlet 113 communicates the main cavity 111, the sub-cavity 112 communicates the sub-valve water inlet 1314, and the sub-cavity 112 communicates the raw water inlet 113 through the main cavity 111, which can simplify the flow path of the raw water transportation and simplify the structure of the water softener valve.

[0163] The above describes the structure and state of the sub-valve assembly 130 in the salt suction mode, that is, the path of the mixed solution to the softening device 190, and the following describes the flow path of the sewage generated after the mixed solution regenerates the softening material in the softening device 190.

[0164] Referring to Figure 21As shown, in the case that the main valve core comprises the main static valve plate 122 and the main dynamic valve plate 121, the main static valve plate 122 is provided with a water passing hole 1221 and a main valve blowdown hole 1222, the main dynamic valve plate 121 comprises a main valve water inlet 1211 and a main valve first groove body 1212, the main valve first groove body 1212 is connected with the water passing hole 1221 and the main valve blowdown hole 1222 to form a first blowdown flow channel 125, the water passing hole 1221 is communicated with the raw water outlet 118, the main valve water inlet 1211 is communicated with the raw water inlet 113, and the main valve static valve plate separates the main valve water inlet 1211 from the raw water outlet 118. The sewage in the softening device 190 is discharged by cooperation of the water passing hole 1221, the main valve first groove body 1212 and the main valve blowdown hole 1222, and the water passing hole 1221 is always communicated with the raw water outlet 118, which can simplify the structure of the valve shell 110 and the main static valve plate 122.

[0165] Of course, the main static valve plate 122 can also be provided with two blowdown holes (not shown in the figure), one of which is communicated with the raw water outlet 118, and the other of which is communicated with the blowdown port 115 of the valve shell 110, and the two blowdown holes are communicated through the groove body of the main dynamic valve plate 121, which can also discharge the sewage in the softening device 190.

[0166] In the case that the auxiliary static valve plate 132 is configured with a softening connection hole 1322, a brine outlet 1323 and a salt suction and water injection hole 1324, and the auxiliary dynamic valve plate 131 is configured with an auxiliary valve third groove body 1313 and an auxiliary valve water inlet 1314, the water injection mode of the auxiliary valve core is described.

[0167] In the water injection mode, referring to Figure 18 As shown, the auxiliary dynamic valve plate 131 is provided with an auxiliary valve first groove body 1311, the auxiliary valve first groove body 1311 is communicated with the salt suction and water injection hole 1324 and the softening connection hole 1322 to form a water injection flow channel 134, the softening connection hole 1322 is communicated with the soft water inlet 119, the salt suction and water injection hole 1324 is communicated with the jet inlet 161 of the jet channel, so that the water flows along the path of the soft water inlet 119, the water injection flow channel 134, the jet channel and the salt tank connection port 1110, that is, the water enters the jet channel along the soft water inlet 119, the softening connection hole 1322, the auxiliary valve first groove body 1311, the salt suction and water injection hole 1324 and the jet inlet 161, and then enters the salt tank 200 through the jet channel and the salt tank connection port 1110.

[0168] It should be noted that the path for sending the soft water into the salt tank 200 is provided herein, only the water flow path after the soft water flows out of the softening device 190 is provided, and the path for the raw water to flow to the softening device 190 is not introduced, which can be referred to the above-mentioned water production mode, that is, the water production channel 124 is communicated to send the raw water in the main cavity 111 to the raw water outlet 118, of course, other paths can also be used.

[0169] When the soft water is sent into the jet flow channel, the jet flow outlet 162 is closed, the jet flow inlet 161 is communicated with the salt suction water hole 1324, and the suction inlet 163 is communicated with the salt tank connecting port 1110, so that the water flows into the jet flow inlet 161 through the salt suction water hole 1324, and the water in the jet flow channel flows to the salt tank connecting port 1110 through the suction inlet 163.

[0170] Based on the fact that the jet flow outlet 162 corresponds to the salt water outlet 1323, the closing of the jet flow outlet 162 can be achieved by moving the secondary movable valve disc 131 to close the salt water outlet 1323, so that the water in the jet flow channel enters the salt tank connecting port 1110 through the suction inlet 163.

[0171] In combination with the above-mentioned description of the types of the main valve assembly 120 and the secondary valve assembly 130, when the secondary valve assembly 130 is a disc valve, the secondary driving part is used to drive the secondary movable valve disc 131 to rotate relative to the secondary static valve disc 132, so as to switch the secondary valve core between the position where the water injection flow channel 134 is communicated and the position where the first salt suction flow channel 135 and the second salt suction flow channel 136 are communicated.

[0172] After the water injection mode and the salt suction mode, the regeneration of the softening material in the softening device 190 is achieved, and the softening device 190 also needs to be cleaned, that is, the soft water valve can control the cleaning mode to be executed, the cleaning mode includes at least one of the backwashing mode and the forward washing mode, and the softening device 190 and the soft water valve can be cleaned.

[0173] The backwashing mode will be described below.

[0174] Reference Figures 23 to 25 As shown in the backwashing mode, the backwashing flow channel 137 of the secondary valve core is communicated, the backwashing flow channel 137 communicates the soft water inlet 119 with the raw water inlet 113, so that the raw water is sent into the softening device 190 through the backwashing flow channel 137 and the soft water inlet 119, the first blowdown flow channel 125 of the main valve core is communicated, the first blowdown flow channel 125 communicates the raw water outlet 118 with the blowdown port 115 of the valve housing 110, so that the water in the softening device 190 enters the soft water valve along the raw water outlet 118, and is discharged along the path of the raw water outlet 118, the first blowdown flow channel 125 and the blowdown port 115.

[0175] The backwash channel 137 is connected to the raw water inlet 113 through the secondary cavity 112, that is, the secondary cavity 112 is connected to the raw water inlet 113. The secondary cavity 112 can be connected to the raw water inlet 113 through the main cavity 111, and the raw water is used to clean the softening device 190.

[0176] Understandably, reference Figure 24 As shown, when the main valve core includes a main stationary valve plate 122 and an active valve plate 121, the main stationary valve plate 122 is provided with a water passage hole 1221 and a main valve drain hole 1222. The active valve plate 121 includes a main valve inlet 1211 and a main valve first groove 1212. The main valve first groove 1212 is connected to the water passage hole 1221 and the main valve drain hole 1222 to form a first drain channel 125. The water passage hole 1221 is connected to the raw water outlet 118 to ensure that the water in the softening device 190 is discharged outward along the raw water outlet 118, the water passage hole 1221, the main valve first groove 1212 and the main valve drain hole 1222. Among them, the main valve inlet 1211 is connected to the raw water inlet 113, the main cavity 111 is filled with raw water, and the main static valve plate 122 isolates the main valve inlet 1211 from the raw water outlet 118, preventing the raw water in the main cavity 111 from flowing to the raw water outlet 118.

[0177] It should be noted that both the backwash mode and the brine suction mode drain water outward through the first sewage discharge channel 125, which simplifies the structure of the main valve assembly 120 and the flow path arrangement in the soft water valve.

[0178] This can also be understood as follows: in both backwashing and brine suction modes, the main valve assembly 120 is in the same state, draining water to the outside of the soft water valve through the main valve assembly 120. However, the drainage path is not limited to the aforementioned first drain channel 125; it can also be a structure not shown in the figure, such as the aforementioned technical solution of "two drain holes on the main stationary valve plate 122." For details, please refer to the above content, which will not be repeated here. In other words, during the switching from brine suction mode to backwashing mode, only the state of the auxiliary valve assembly 130 can be adjusted, while the state of the main valve assembly 120 can remain unchanged.

[0179] Based on the structure of the secondary valve assembly 130 in the above-mentioned salt absorption mode, the structure and function of the secondary valve assembly 130 in the backwash mode will be explained.

[0180] Understandably, reference Figure 25 As shown, the auxiliary static valve plate 132 is provided with a softening connection hole 1322, and the auxiliary dynamic valve plate 131 is provided with a auxiliary valve inlet 1314. The auxiliary valve inlet 1314 is connected to the raw water inlet 113. The auxiliary valve inlet 1314 and the softening connection hole 1322 are connected to form a backwash channel 137. The softening connection hole 1322 is connected to the soft water inlet 119, so that the raw water enters the softening device 190 along the path of the auxiliary valve inlet 1314, the softening connection hole 1322, and the soft water inlet 119, and the raw water is sent into the softening device 190.

[0181] Based on the foregoing, the auxiliary valve water inlet 1314 is communicated with the raw water inlet 113 through the auxiliary cavity 112.

[0182] It can be understood that the valve housing 110 is configured with a communication channel 1111, which communicates the main cavity 111 with the auxiliary cavity 112, the main cavity 111 is communicated with the raw water inlet 113, the auxiliary cavity 112 is communicated with the auxiliary valve water inlet 1314, and the auxiliary cavity 112 can be communicated with the raw water inlet 113 through the main cavity 111. The structure of the water softener valve is simple, and the flow of raw water is smooth.

[0183] In the case that the communication channel 1111 communicates the main cavity 111 with the auxiliary cavity 112, in the water production mode, the auxiliary valve core blocks the auxiliary cavity 112 from the soft water inlet 119, avoiding the raw water in the auxiliary cavity 112 affecting the water supply of the softening device 190 to the soft water inlet 119, and ensuring that the user can take soft water from the soft water outlet 114.

[0184] The above describes the backwashing mode, and the following describes the forward washing mode.

[0185] Reference Figures 26 to 28 In the forward washing mode, the second blowdown flow passage 138 of the auxiliary valve core is communicated, the second blowdown flow passage 138 communicates the soft water inlet 119 with the blowdown channel 1115 of the valve housing 110, the raw water outlet 118 is communicated with the raw water inlet 113, the raw water in the water softener valve enters the softening device 190 through the raw water outlet 118, the water in the softening device 190 is communicated into the water softener valve through the soft water inlet 119, to be discharged through the second blowdown flow passage 138 of the auxiliary valve core and the blowdown channel 1115 of the valve housing 110, to realize the discharge of the sewage for cleaning the softening device 190.

[0186] The structure of the auxiliary valve core that can form the second blowdown flow passage 138: reference Figure 28 As shown in the figure, the auxiliary static valve piece 132 is configured with an auxiliary valve blowdown hole 1321 and a softening connection hole 1322, the auxiliary valve blowdown hole 1321 is communicated with the blowdown channel 1115, and the softening connection hole 1322 is communicated with the soft water inlet 119. The auxiliary dynamic valve piece 131 is configured with an auxiliary valve first groove body 1311, which communicates the softening connection hole 1322 with the auxiliary valve blowdown hole 1321 to form the second blowdown flow passage 138. The water discharged from the softening device 190 flows along the path of the soft water inlet 119, the softening connection hole 1322, the auxiliary valve first groove body 1311 and the auxiliary valve blowdown hole 1321, and then is discharged from the water softener valve through the auxiliary valve blowdown hole 1321 and the blowdown channel 1115, and can be discharged to the target position through the drain pipeline.

[0187] It can be understood that reference Figure 27As shown, in the backwash mode, the raw water outlet 118 and the raw water inlet 113 are communicated through the water production flow channel 124. It can also be understood that the state of the main valve core in the backwash mode is the same as that in the water production mode, that is, the main valve core is in the first main valve position. When the main valve core is in the first main valve position, the water production mode and the backwash mode can be switched by adjusting the state of the auxiliary valve core.

[0188] The auxiliary driving part is used to drive the auxiliary valve core to rotate to communicate or disconnect the second blowdown flow channel 138, that is, the auxiliary driving part can realize the state switching of the auxiliary valve core by driving the auxiliary moving valve piece 131 to rotate relative to the auxiliary static valve piece 132, and further realize the function mode switching of the water softener valve.

[0189] When the water softener valve executes the salt absorption mode, the softening device 190 needs to be cleaned. The cleaning mode of the softening device 190 can be at least one of the backwash mode and the backwash mode described above. When the cleaning mode includes the backwash mode or the backwash mode, the softening device 190 can be cleaned by the backwash mode or the backwash mode after the salt absorption mode is executed. When the cleaning mode includes the backwash mode and the backwash mode, the backwash mode or the backwash mode can be executed first after the salt absorption mode is completed, which can be selected as needed. In some cases, after the salt absorption mode, the backwash mode is executed first, and then the backwash mode is executed.

[0190] It should be noted that the holes of the main static valve piece 122 and the holes of the auxiliary static valve piece 132 are provided with openings corresponding to the holes and communicated with the holes on the valve housing 110, so that water can flow out through the holes of the static valve piece.

[0191] The above describes the flow paths corresponding to each mode of the water softener valve. Next, the control method of the water softener valve is described.

[0192] Based on the above, the main valve assembly 120 includes two main valve positions, and the auxiliary valve assembly 130 includes a plurality of auxiliary valve positions. The positional relationship between the main valve assembly 120 and the auxiliary valve assembly 130 is described.

[0193] It can be understood that the main driving part is used to drive the main valve core to switch between the first main valve position and the third main valve position, and the auxiliary driving part is used to drive the auxiliary valve core to switch between a plurality of auxiliary valve positions, so that the water softener valve can switch between the water production mode, the water injection mode, the salt absorption mode and the cleaning mode.

[0194] When the water softener includes four modes, the auxiliary valve core can include four auxiliary valve positions or three auxiliary valve positions. When the water softener includes five modes, the auxiliary valve core can include five auxiliary valve positions or four auxiliary valve positions. The flow path communicated by the auxiliary valve core is different when the auxiliary valve core is in different auxiliary valve positions. Referring to Figures 13 to 28As shown, the water softener includes five modes, and the auxiliary spool includes five auxiliary valve positions.

[0195] Referring to Figure 15 , Figure 18 , Figure 21 , Figure 24 and Figure 27 , the main spool is switched between the first main valve position and the third main valve position, that is, the positions of the main spool are the same in at least two modes, which can simplify the regulation mode of the main spool.

[0196] In some cases, referring to Figure 15 , Figure 18 and Figure 27 , the main spool is in the first main valve position, the water production flow passage 124 of the main spool is connected to the main cavity 111 and the raw water outlet 118, and at the same time, the main cavity 111 is connected to the raw water inlet 113, that is, the raw water in the raw water inlet 113 can be delivered to the raw water outlet 118 through the main spool to realize the process of delivering raw water to the softening device 190, and at this time, the position switching of the auxiliary spool is used to switch the water softener between the water production mode and the water injection mode.

[0197] When the cleaning mode includes a forward washing mode, the main spool is in the first main valve position, and the position switching of the auxiliary spool can be used to switch the water softener to the forward washing mode. The structure of the water production flow passage 124 can refer to the above description of the water production mode, the water injection mode, and the forward washing mode, for example, the main static valve piece 122 is provided with a water passing hole 1221, the main dynamic valve piece 121 is provided with a main water inlet 1211, and in the first main valve position, the main water inlet 1211 is connected to the raw water inlet 113, and the water passing hole 1221 is connected to the main water inlet 1211 to form the water production flow passage 124.

[0198] In other cases, referring to Figure 21 and Figure 24 , the main spool is in the third main valve position, the first blowdown flow passage 125 of the main spool is connected, the water production flow passage 124 is disconnected, and the first blowdown flow passage 125 is connected to the raw water outlet 118 and the blowdown passage 1115 of the valve housing 110 to discharge sewage along the raw water outlet 118, the first blowdown flow passage 125, and the blowdown passage 1115. In the third main valve position, the main spool is used to guide the sewage in the softening device 190 out. In the mode requiring sewage discharge, the main spool can be switched to the third main valve position, and at this time, the softening device 190 can be supplied with water through the auxiliary spool and the soft water inlet 119.

[0199] When the cleaning mode includes the backwash mode, the main valve core is in the third main valve position, and the switching of the position of the auxiliary valve core realizes the switching of the water softener valve between the salt suction mode and the backwash mode. It can be understood that, in the salt suction mode and the backwash mode, the auxiliary valve core sends water to the softening device 190, and the main valve core leads the sewage in the softening device 190 out, and in the two modes, the flow channels communicated by the auxiliary valve core are different. Among them, the structure of the first sewage flow channel 125 can refer to the above-mentioned contents about the salt suction mode and the backwash mode, for example, the main static valve piece 122 is provided with a water passing hole 1221 and a main valve sewage hole 1222, the main dynamic valve piece 121 includes a main valve water inlet 1211 and a main valve first groove body 1212, in the third main valve position, the main valve first groove body 1212 is connected with the water passing hole 1221 and the main valve sewage hole 1222 to form the first sewage flow channel 125, the water passing hole 1221 is communicated with the raw water outlet 118, the main valve water inlet 1211 is communicated with the main cavity 111, and the main valve static valve piece separates the main valve water inlet 1211 from the raw water outlet 118.

[0200] The above-mentioned contents are used to describe two positions of the main valve assembly 120, and the following will be described in combination with the positions of the main valve assembly 120 and the auxiliary valve assembly 130.

[0201] When the water softener includes the water production mode, the water injection mode and the salt suction mode, the auxiliary driving part is used to drive the auxiliary valve core to rotate and switch between the first auxiliary valve position, the second auxiliary valve position and the fourth auxiliary valve position, the first auxiliary valve position, the second auxiliary valve position and the fourth auxiliary valve position are sequentially arranged along the circumference of the auxiliary valve core, so as to facilitate the position adjustment of the auxiliary valve core.

[0202] Reference Figure 15 and Figure 16 As shown in the water production mode, the auxiliary valve core is in the first auxiliary valve position, the main valve core is in the first main valve position, the main valve core is used to lead water to the softening device 190, the soft water inlet 119 is communicated with the soft water outlet 114, the auxiliary valve core is used to disconnect the soft water inlet 119 from other flow channels, to ensure the soft water outlet 114 and avoid the pollution of water in other flow channels to the soft water.

[0203] Reference Figure 18 and Figure 19 As shown in the water injection mode, the auxiliary valve core is in the fourth auxiliary valve position, the main valve core is in the first main valve position, the main valve core is used to lead water to the softening device 190, and the auxiliary valve core is used to lead the soft water in the softening device 190 into the salt tank connecting port 1110. In the fourth auxiliary valve position, the water injection flow channel 134 of the auxiliary valve core is communicated, the water injection flow channel 134 is communicated with the soft water inlet 119 and the salt tank connecting port 1110.

[0204] Reference Figure 21 and Figure 22As shown, in the salt suction mode, the sub-valve core is at the second sub-valve position, the main valve core is at the third main valve position, the sub-valve core is used to pass the raw water into the jet device 160, and under the flow power of the raw water, the salt solution in the salt tank connecting port 1110 is sucked into the jet device 160, and the mixed solution in the jet device 160 is sent into the softening device 190, and the water in the softening device 190 is discharged along the valve shell 110 through the main valve core. Among them, in the second sub-valve position, the first salt suction flow channel 135 and the second salt suction flow channel 136 of the sub-valve core are communicated, the jet inlet 161 of the jet channel is communicated with the sub-cavity 112 through the first salt suction flow channel 135, the suction inlet 163 of the jet channel is communicated with the salt tank connecting port 1110, and the jet outlet 162 of the jet channel is communicated with the soft water inlet 119 through the second salt suction flow channel 136.

[0205] Referring to Figure 24 and Figure 25 As shown, when the cleaning mode includes the backwashing mode, the sub-valve core further includes a fifth sub-valve position, in the backwashing mode, the sub-valve core is at the fifth sub-valve position, the main valve core is at the third main valve position, and the sub-valve core is used to pass the raw water into the softening device 190, and the water in the softening device 190 is discharged along the valve shell 110 through the main valve core. In the fifth sub-valve position, the backwashing flow channel 137 of the sub-valve core is communicated, and the backwashing flow channel 137 is communicated with the soft water inlet 119 and the sub-cavity 112.

[0206] Referring to Figure 27 and Figure 28 As shown, when the cleaning mode includes the forward washing mode, the sub-valve core further includes a third sub-valve position, in the forward washing mode, the sub-valve core is at the third sub-valve position, the main valve core is at the first main valve position, and the main valve core is used to pass the raw water into the softening device 190, and the water in the softening device 190 is discharged along the valve shell 110 through the sub-valve core. In the third sub-valve position, the second blowdown flow channel 138 of the sub-valve core is communicated, the second blowdown flow channel 138 is communicated with the soft water inlet 119 and the blowdown channel 1115 of the valve shell 110, and the sub-valve first groove body 1311 is communicated with the softening connecting hole 1322 and the sub-valve blowdown hole 1321 to form the second blowdown flow channel 138.

[0207] For the state and function mode of the soft water valve, the structure of each flow channel is not described here, and can be combined with the above description of each mode.

[0208] Referring to Figure 34 and Figure 35 As shown, when the sub-valve core includes a first sub-valve position, a second sub-valve position, a third sub-valve position, a fourth sub-valve position and a fifth sub-valve position, the first sub-valve position, the second sub-valve position, the third sub-valve position, the fourth sub-valve position and the fifth sub-valve position are sequentially arranged along the circumference of the sub-valve core, and the sub-driving part can drive the sub-valve core to move to the corresponding sub-valve position by driving the sub-moving valve piece 131 to rotate.

[0209] During the operation of the water softener valve, the water softener valve is mainly in the water production mode. When the softening material in the softening device 190 needs to be regenerated, water is first injected into the brine tank 200 to execute the water injection mode, and then the brine suction mode is executed to send a mixed solution of salt solution with regeneration function into the softening device 190. After that, the cleaning mode is executed. When the cleaning mode includes forward washing mode and backwash mode, the backwash mode can be executed first, and then the forward washing mode can be executed.

[0210] In water production mode, the main valve core is in the first main valve position, and the auxiliary valve core is in the first auxiliary valve position. When water injection mode is required, the position of the main valve core does not need to be adjusted, and the auxiliary valve core is adjusted to the fourth auxiliary valve position. After water injection mode, the brine tank 200 needs to perform a preset brine dissolution time to obtain a brine solution. At this time, it can be switched to water production mode, the position of the main valve core does not need to be adjusted, and the auxiliary valve core can return to the first auxiliary valve position. After brine dissolution is completed, the brine suction mode is executed, requiring the main valve core to be adjusted to the third main valve position and the auxiliary valve core to the second auxiliary valve position. Taking the brine suction mode followed by the backwash mode as an example, at this time, the position of the main valve core does not need to be adjusted, the auxiliary valve core is adjusted to the fifth auxiliary valve position, and then the forward wash mode is executed. The main valve core needs to be adjusted to the first main valve position, and the auxiliary valve core needs to be adjusted to the third auxiliary valve position to complete the regeneration process of the softening material. Finally, the softened water valve is switched to water production mode to continue the water production function.

[0211] In some cases, refer to Figure 43 As shown, the main valve core also includes a second main valve position. The main valve core is adapted to switch between the first main valve position, the second main valve position, and the third main valve position. In the second main valve position, the main valve core isolates the raw water inlet 113 from the raw water outlet 118. At this time, the water in the raw water inlet 113 will not enter the softening valve, and the water supply to the main chamber 111, the secondary chamber 112, and the softening device 190 will stop. The pressure of the water flow on the secondary valve core in the secondary chamber 112 will decrease, which can reduce the resistance of the water pressure to the position switching of the secondary valve core, making the position switching of the secondary valve core easier. This can reduce the driving force provided by the secondary drive unit to the secondary valve plate 131, reduce power consumption, reduce the wear of the secondary valve assembly 130, and help extend the life of the secondary valve assembly 130 and the life of the softening valve.

[0212] In the second main valve position, the active valve plate closes the water passage hole of the main stationary valve plate. The water passage hole can be closed by the surface of the active valve plate or by the second groove of the active valve plate. There are various ways to close the water passage hole, which are not limited here and can be selected as needed.

[0213] The main valve core is in the second main valve position, which controls the auxiliary drive unit to switch the auxiliary valve core between multiple auxiliary valve positions. Before the auxiliary valve core needs to switch positions, switching the main valve core to the second main valve position reduces the resistance of water pressure to the auxiliary valve core position switching, making the auxiliary valve core position switching more effortless and easier to operate.

[0214] In the case that the main valve core comprises the first main valve position or the second main valve position, in the process that the main valve core switches from the first main valve position to the second main valve position, the main valve blowdown hole 1222 is communicated with the water passing hole 1221, based on the blowdown hole of the valve housing communicated with the main valve blowdown hole 1222, the raw water outlet is communicated with the water passing hole 1221, the pressure in the softening device can be discharged through the path of the raw water outlet, the water passing hole 1221, the main valve blowdown hole 1222 and the blowdown hole, the pressure between the softening device and the water softener valve will be unloaded, and the pressure in the softening device will not become larger after being discharged, after the pressure in the softening device is discharged through the main valve core, the pressure between the auxiliary static valve plate 132 and the softening device can be reduced, if the pressure is not discharged, the pressure in the softening device will be transmitted to the auxiliary cavity and between the auxiliary static valve plate 132 and the auxiliary dynamic valve plate 131 through the softening connection hole 1322 of the auxiliary static valve plate 132, and the motor torque will be increased, the second main valve position also has the function of reducing the torque of the auxiliary valve core.

[0215] Similarly, when the main valve core switches from the third main valve position to the second main valve position, the main valve blowdown hole 1222 is also communicated with the water passing hole 1221, and the above-mentioned effect can be achieved, which will not be described here.

[0216] In the process that the main valve core switches from the first main valve position to the second main valve position, the main valve blowdown hole 1222 is communicated with the water passing hole 1221 through the main valve second groove body 1213; in the process that the main valve core switches from the third main valve position to the second main valve position, the main valve blowdown hole 1222 is communicated with the water passing hole 1221 through the main valve first groove body 1212.

[0217] It can be understood that when the water making mode is switched to the water injection mode, the position of the main valve core needs to be adjusted to the second main valve position first, and then the position of the auxiliary valve core is adjusted to the fourth auxiliary valve position. After the adjustment of the auxiliary valve core is completed, the main valve core returns to the first main valve position, and then the water injection process can be performed. After the water injection is completed, the main valve core is adjusted to the second main valve position again, and then the auxiliary valve core returns to the first auxiliary valve position. At this time, the salt tank connection port 1110 is in a salt melting state, the water softener valve is in a water making mode, and the user can take water. After the salt melting is completed, the salt suction mode is performed. At this time, the main valve core is first adjusted to the second main valve position, and then the auxiliary valve core is adjusted to the second auxiliary valve position. Then the main valve core is adjusted to the third main valve position to perform the salt suction mode. After the salt suction mode is completed, the backwashing mode is adjusted. At this time, the main valve core is first adjusted to the second main valve position, and then the auxiliary valve core is adjusted to the fifth auxiliary valve position. Then the main valve core is adjusted to the third main valve position to perform the backwashing mode. After the backwashing mode, the forward washing mode is adjusted. At this time, the main valve core is first adjusted to the second main valve position, and then the auxiliary valve core is adjusted to the third auxiliary valve position. Then the main valve core is adjusted to the first main valve position to perform the forward washing mode. After the forward washing mode is completed, the water making mode needs to be adjusted. The main valve core is first adjusted to the second main valve position, and then the auxiliary valve core is adjusted to the first auxiliary valve position. Then the main valve core is adjusted to the first main valve position, and the water making can be performed.

[0218] In the second main valve position, the water passage hole 1221 is disconnected from the main valve water inlet 1211, and the water passage hole 1221 is disconnected from the main valve water inlet 1211 through other parts of the main driven valve piece 121, which is simple in structure. When the main driven valve piece 121 is provided with the main valve second groove body 1213, in the second main valve position, the water passage hole 1221 is at least partially located in the main valve second groove body 1213 in the orthographic projection of the main driven valve piece 121. The water passage hole 1221 corresponds to the main valve second groove body 1213, which is clever in structure design and can reduce the torque of the main driven valve piece 121 relative to the main static valve piece 122. In some cases, the opening area of the main valve second groove body 1213 is larger than the opening area of the water passage hole 1221, and the second main valve position is simple to adjust.

[0219] In the first main valve position, the water passage hole 1221 is connected to the main valve water inlet 1211, and the water from the raw water inlet can be connected to the raw water outlet.

[0220] The valve housing is also provided with a blowdown port, and the main valve core can connect or disconnect the raw water outlet and the blowdown port. In the second main valve position, the main valve core disconnects the raw water outlet and the blowdown port, avoids being discharged through the main valve core, and ensures that the water in and out of the water softener valve is blocked. In the case where the main valve core includes the main static valve piece 122 and the main driven valve piece 121, the main static valve piece 122 is provided with a main valve blowdown hole 1222, which is connected to the blowdown port. In the second main valve position, the main valve blowdown hole 1222 can be connected or disconnected to the raw water outlet through the main driven valve piece 121, which is simple in structure.

[0221] When the main static valve plate 122 is configured with the water passing hole 1221, the main active valve plate 121 includes the main valve first groove body 1212, and the main valve core is connected to the water passing hole 1221 through the main valve first groove body 1212 and the main valve drain hole 1222 at the third main valve position, so that the water can be drained through the main valve core.

[0222] At the second main valve position, the main valve drain hole 1222 is located in the main valve first groove body 1212 in the orthographic projection of the main active valve plate 121, so that the frictional resistance between the main active valve plate 121 and the main static valve plate 122 can be reduced, and the torque for rotating the main active valve plate 121 can be reduced.

[0223] The main active valve plate 121 is provided with the main valve second groove body 1213, and the main valve drain hole 1222 is located in the main valve second groove body 1213 in the orthographic projection of the main active valve plate 121 at the first main valve position, so that the main valve drain hole 1222 corresponds to the main valve second groove body 1213, and the torque for rotating the main active valve plate 121 can also be reduced.

[0224] The above describes the water production mode of the water softener, other functional modes for regenerating the softening material in the softening device 190, and the switching between the modes. Based on the above technical solutions, when the water softener is applied to a water softener machine, the user can obtain soft water with a single hardness from the water softener machine, that is, the hardness of the soft water produced by the water softener machine cannot be adjusted conveniently. Therefore, the following technical solutions provide a water softener with adjustable hardness.

[0225] It can be understood that, as shown in Figures 29 to 32 The valve housing 110 includes a raw water passage and a soft water passage. The raw water passage is located between the raw water inlet 113 and the main cavity 111, and the soft water passage is located between the soft water outlet 114 and the auxiliary cavity 112. The soft water passage communicates the soft water outlet 114 and the soft water inlet 119. The raw water passage and the soft water passage are connected or disconnected through the bypass valve 140. When the bypass valve 140 connects the raw water passage and the soft water passage, the raw water in the raw water passage can flow to the soft water passage under the water inlet pressure of the raw water inlet 113 of the raw water passage, so as to adjust the water hardness of the soft water outlet 114 by introducing raw water into the soft water passage.

[0226] The bypass valve 140 is connected between the raw water passage and the soft water passage, and the installation position of the bypass valve 140 is flexible, which is helpful to reduce the size of the water softener.

[0227] In some cases, as shown in Figure 1As shown, the valve housing 110 is connected with a flow meter 150, which is located between the soft water inlet 119 and the bypass valve 140, and is used to detect the flow rate of the soft water. According to the hardness of the soft water set by the user and the softened hardness of the soft water inlet 119, the flow rate of the raw water required to be introduced into the soft water passage is calculated, and the opening degree of the bypass valve 140 is adjusted to adjust the hardness of the outlet water according to the user's demand.

[0228] In some cases, the flow meter 150 is located between the bypass valve 140 and the soft water outlet 114, and is used to detect the flow rate of the soft water outlet 114.

[0229] In some cases, when the soft water device does not produce water, the bypass valve 140 can also connect the raw water passage and the soft water passage, and the user can take raw water from the soft water outlet 114.

[0230] The bypass valve 140 has various structures and can be selected as needed. For reference Figures 30 to 32 As shown, the bypass valve 140 can be a disc valve, which is simple in structure and convenient to disassemble and assemble.

[0231] For reference Figure 30 and Figure 31 As shown, the first shell part 1140 of the valve housing 110 forms a raw water passage, the second shell part 1141 of the valve housing 110 forms a soft water passage, the first shell part 1140 is provided with a first communication port 1134 communicating with the raw water passage, the second shell part 1141 is provided with a second communication port 1135 communicating with the soft water passage, and the valve housing 110 further forms a bypass cavity, in which a bypass valve core of the bypass valve 140 is located, and the bypass valve core is used to adjust the on-off of the first communication port 1134 and the second communication port 1135.

[0232] For reference Figure 32 As shown, the bypass valve core can include a bypass static valve plate 142 and a bypass dynamic valve plate 141. The bypass static valve plate 142 is provided with a first bypass opening 1421 and a second bypass opening 1422, the first bypass opening 1421 corresponds to and communicates with the first communication port 1134, and the second bypass opening 1422 corresponds to and communicates with the second communication port 1135. The bypass dynamic valve plate 141 can move to close the first bypass opening 1421 and the second bypass opening 1422, at which time the bypass valve 140 is closed, and the raw water passage and the soft water passage are disconnected. The bypass dynamic valve plate 141 can move to open the first bypass opening 1421 and the second bypass opening 1422, at which time the bypass valve 140 is opened, and the raw water passage and the soft water passage are connected. The bypass dynamic valve plate 141 includes a first fan-shaped part 1411 and a second fan-shaped part 1412, the first fan-shaped part 1411 is used to open and close the first bypass opening 1421, and the second fan-shaped part 1412 is used to open and close the second bypass opening 1422, which is simple in structure and convenient to process.

[0233] The bypass movable valve piece 141 is connected to a bypass motor 143, which is used to drive the rotation of the bypass movable valve piece 141, and the bypass valve 140 is switched by the rotation of the bypass movable valve piece 141.

[0234] Reference Figures 30 to 32 As shown in the drawings, the valve housing 110 is provided with a bypass chamber, which is in the form that the valve housing 110 is formed with a bypass groove 1132, the bypass groove 1132 is communicated with a first communication port 1134 and a second communication port 1135, the bypass valve core is installed in the bypass groove 1132 through the opening of the bypass groove 1132, and the opening of the bypass groove 1132 is closed by a cover piece 1133 to form the bypass chamber. The structure of the bypass chamber is simple, which is convenient for the molding of the valve housing 110 and the disassembly and assembly of the bypass valve 140. The bypass static valve piece 142 is sealed and connected to the inner wall of the valve housing 110 through a bypass sealing ring 144.

[0235] Reference Figure 33 As shown in the drawings, the user can also take raw water through the water softening valve, at this time, the main valve core can be in the second main valve position.

[0236] Next, the structure of the valve housing 110 will be described.

[0237] Reference Figures 1 to 4 、 Figures 39 to 41 As shown in the drawings, the valve housing 110 includes a first housing part 1140, a second housing part 1141 and a third housing part 1142. The first housing part 1140 is formed with a raw water passage, the second housing part 1141 is formed with a soft water passage, and the third housing part 1142 is formed with the main chamber 111 and the auxiliary chamber 112. The third housing part 1142 is also formed with a raw water outlet 118 and a soft water inlet 119, which are located on the same side of the third housing part 1142 to facilitate the installation of the softening device 190.

[0238] The first housing part 1140, the second housing part 1141 and the third housing part 1142 are fixed as an integrated valve housing 110, which simplifies the structure of the valve housing 110.

[0239] The first housing part 1140 and the second housing part 1141 are arranged side by side, and the third housing part 1142 is located at one end of the first housing part 1140 and the second housing part 1141. The main chamber 111 and the auxiliary chamber 112 are arranged side by side, the main chamber 111 is located on the same side (right side) of the first housing part 1140, and the auxiliary chamber 112 is located on the same side (left side) of the second housing part 1141. The structure distribution of the valve housing 110 is more reasonable.

[0240] One end of the first shell portion 1140 (raw water channel) forms a raw water inlet 113, and the other end forms a main cavity inlet 116. The main cavity inlet 116 connects the raw water channel and the main cavity 111, and the raw water channel and the main cavity 111 remain in a connected state.

[0246] It should be noted that during the regeneration of the softened material, the main valve drain hole 1222 and the auxiliary valve drain hole 1321 work independently and will not work simultaneously. When the two drain holes are connected to the drain port 115 through the drain channel 1115, when the main valve drain hole 1222 is working, the auxiliary valve drain hole 1321 is not working, and there will be no sewage backflow. Similarly, when the auxiliary valve drain hole 1321 is working, the main valve drain hole 1222 is not working.

The filter channel 1118 extends away from the third housing portion 1142 along the brine inlet 1119, and the extension direction of the filter channel 1118 is the same as the extension direction of the installation channel 117. For example, the filter channel 1118 and the installation channel 117 are arranged vertically, which means that the brine inlet 1119 and the brine outlet 1120 are arranged vertically. The valve housing 110 is connected with an end cap 170, which covers the ends of the filter channel 1118 and the installation channel 117.

The cover 1113 is arranged on the housing to close the first opening. The blowdown groove 1116 is closed by the cover 1113 to form the blowdown channel 1115. One end of the blowdown groove 1116 is formed with the blowdown port 115, and the other end of the blowdown groove 1116 is closed. The position of the blowdown port 115 can be arranged on the opposite side of the installation channel 117. The function of the blowdown channel 1115 is the same as the above, and the structure of the blowdown channel 1115 is different. The structure of the blowdown channel 1115 is not limited to the foregoing structure, and can also be selected as needed.

[0251] When the valve housing 110 is provided with the communication channel 1111, the extension direction of the communication channel 1111 can be the same as but not limited to the blowdown channel 1115. In some cases, as shown in Figure 1 、 Figure 41 As shown, the valve housing 110 can be formed with a communication groove 1112, and the length direction of the communication groove 1112 is formed with a second opening. The cover 1113 is arranged on the housing to close the second opening. The communication groove 1112 can also be closed by the cover 1113 to form the communication channel 1111, so that the communication channel 1111 is formed in the valve housing 110 to communicate the main cavity 111 and the auxiliary cavity 112. The extension direction of the communication groove 1112 can be the same as the blowdown groove 1116. The communication groove 1112 and the blowdown groove 1116 can use the same cover 1113 or be provided with independent covers 1113, respectively. The specific selection can be made as needed. As shown in Figure 39 and Figure 40 The end of the communication channel 1111 can also be formed with a communication process port 1114, which can be closed by the end cover 170. The end of the communication channel 1111 away from the second opening can communicate with the raw water channel, or the communication channel 1111 communicates with the raw water channel through the main cavity 111. The communication channel 1111 can make the main cavity 111 and the auxiliary cavity 112 always full of raw water. The communication channel 1111 can be arranged at the lowermost position (as shown in Figure 39 and Figure 40 ) or the uppermost position (as shown in Figure 1 and Figure 41).

[0252] In some cases, refer to Figure 39 and Figure 40 As shown, the valve housing 110 has a connecting channel 1111 with an end opening. The connecting channel 1111 is closed by an end cap 170. The connecting channel 1111 can share an end cap 170 with at least one of the above-mentioned installation channel 117, filter channel 1118, and sewage discharge channel 1115, or it can be equipped with an independent plug to close the opening of the connecting channel 1111.

[0253] The above describes the structure of valve housing 110. The following describes the structure of main valve assembly 120 and auxiliary valve assembly 130.

[0254] Main valve assembly 120:

[0255] refer to Figures 5 to 28 As shown, the main valve assembly 120 includes a main valve core and a main drive unit. The main valve core includes a main stationary valve plate 122 and an active valve plate 121. The main stationary valve plate 122 is fixed in the main cavity 111 of the valve housing 110. The active valve plate 121 is rotatably disposed in the main cavity 111. The active valve plate 121 has a main valve inlet 1211. The main stationary valve plate 122 has a water passage 1221. When the active valve plate 121 rotates to the point where the main valve inlet 1211 communicates with the water passage 1221, it can communicate with the water supply channel 124 of the main valve core. The raw water in the main cavity 111 can be sent to the softening device 190 through the raw water outlet 118 of the main valve core flow channel.

[0256] When the main valve inlet 1211 is connected to the water passage 1221, the main valve inlet 1211 faces the main cavity inlet 116, so that the raw water can flow smoothly through the main valve core to the raw water outlet 118.

[0257] In some cases, the main valve assembly 120 also has a sewage discharge function. The main stationary valve plate 122 has a main valve sewage discharge hole 1222, and the active valve plate 121 has a main valve first groove 1212. When the active valve plate 121 moves to the main valve first groove 1212 to connect the main valve sewage discharge hole 1222 and the water passage hole 1221, a first sewage discharge channel 125 is formed. The sewage in the softening device 190 enters the softened water valve through the raw water outlet 118, and then flows through the water passage hole 1221, the main valve first groove 1212 and the main valve sewage discharge hole 1222 to the sewage discharge channel 1115 of the valve body 110.

[0258] The main valve assembly 120 can switch between supplying water to the softening unit 190 and draining water from the softening unit 190.

[0259] In some cases, the main valve second groove 1213 is provided in the main active valve plate 121, which can reduce the contact area between the main static valve plate 122 and the main active valve plate 121, reduce the friction resistance of the rotation of the main active valve plate 121 relative to the main static valve plate 122, and reduce the torque of the main driving part.

[0260] Referring to Figure 43 As shown, when the main valve core includes a second main valve position, the main active valve plate 121 functions to close the water passage hole 1221 of the main static valve plate 122, and the water passage hole 1221 can be closed by the surface of the main active valve plate 121. When the main active valve plate 121 is provided with the main valve second groove 1213, the main valve second groove 1213 can also close the water passage hole 1221. In this case, the orthographic projection of the water passage hole 1221 on the main active valve plate 121 is located in the main valve second groove 1213, and it can also be understood that the opening area of the main valve second groove 1213 is greater than the flow area of the water passage hole 1221, which can ensure the closing effect of the water passage hole 1221.

[0261] Referring to Figure 43 As shown, the main static valve plate 122 is also provided with a flow guide groove 1223, which extends from the edge of the main static valve plate 122 to the inside of the main static valve plate 122. The flow guide groove 1223 is located on the side of the main static valve plate 122 facing the main active valve plate 121, and the flow guide groove 1223 can guide the water in the main cavity to the space between the main static valve plate 122 and the main active valve plate 121, so as to reduce the contact area between the main static valve plate 122 and the main active valve plate 121 and balance the water pressure between the main static valve plate 122 and the main active valve plate 121 and the water pressure outside them.

[0262] In the case where the main active valve plate 121 is provided with the main valve water inlet 1211, the main valve first groove 1212 and the main valve second groove 1213, the main active valve plate 121 can also be provided with a process groove to reduce the contact area between the main active valve plate 121 and the main static valve plate 122 when the structural strength of the main active valve plate 121 is satisfied.

[0263] When the main valve core is in the first main valve position, the orthographic projection of the main valve blowdown hole 1222 on the main active valve plate 121 is located in the main valve first groove 1212, the main valve second groove 1213 or the process groove, and the main valve blowdown hole 1222 is closed by the groove, which can optimize the sealing effect of the main valve blowdown hole 1222.

[0264] The main driving part comprises a main valve motor 123 and a main shaft assembly 126, the main driving valve 121 is connected to the main shaft assembly 126, the main shaft assembly 126 is connected to the output shaft of the main valve motor 123, and the main driving valve 121 is driven to rotate relative to the main static valve 122 by the main valve motor 123. The main driving valve 121 is also provided with a shielding part 1214, the shielding part 1214 is located at the end of the main shaft assembly 126, the shielding part 1214 is between the main valve water inlet 1211 and the main shaft assembly 126, and the shielding part 1214 plays a role in protecting the main shaft assembly 126.

[0265] The auxiliary valve assembly 130 comprises an auxiliary valve core and an auxiliary driving part for driving the auxiliary valve core to rotate.

[0266] Reference Figures 5 to 28 As shown in the drawings, the auxiliary valve assembly 130 comprises an auxiliary valve core and an auxiliary driving part for driving the auxiliary valve core to rotate, the flow channel structure of the auxiliary valve core is different from that of the main valve core, and the structure of the auxiliary driving part is similar to that of the main driving part.

[0267] The auxiliary valve core comprises an auxiliary static valve 132 and an auxiliary driving valve 131, the auxiliary static valve 132 is fixed in the auxiliary cavity 112, and the auxiliary driving valve 131 is located in the auxiliary cavity 112 and can rotate relative to the auxiliary static valve 132 to adjust the on-off of the flow channel of the auxiliary valve core.

The notch at the side of the auxiliary driving valve 131 forms the auxiliary valve water inlet 1314.

[0269] The auxiliary valve plate 131 can be rotated so that all openings of the auxiliary stationary valve plate 132 are closed by the groove of the auxiliary valve plate 131, at which point the flow channels inside the auxiliary valve core are all disconnected; or, the auxiliary valve plate 131 rotates so that the first groove 1311 of the auxiliary valve connects the softening connection hole 1322 and the brine injection hole 1324, enabling the softening device 190 to connect with the brine tank connection port 1110 through the ejector 160, allowing water to be injected into the brine tank connection port 1110; or, the auxiliary valve plate 131 rotates so that the auxiliary valve inlet 1314 connects to the brine injection port 1119, and the third groove 1313 of the auxiliary valve connects the softening connection hole 1322 and the brine outlet. The raw water in the secondary chamber 112 flows to the ejector 160 through the secondary valve inlet 1314 and the brine injection port 1119. The raw water in the ejector 160 provides driving force, causing the brine solution in the brine tank connection port 1110 to flow to the softening device 190 through the ejector 160, the brine outlet 1323, the third tank of the secondary valve 1313, and the softening connection hole 1322. Alternatively, the secondary valve plate 131 rotates to connect the secondary valve inlet 1314 with the softening connection hole 1322, and the raw water in the secondary chamber 112 enters the softening device 190 through the secondary valve inlet 1314 and the softening connection hole 1322.

The two auxiliary valve inlets 1314 can be independent of each other or connected to each other. When the two auxiliary valve inlets 1314 are connected, the pressure between the auxiliary stationary valve plate 132 and the auxiliary moving valve plate 131 and in the auxiliary cavity 112 can be balanced, reducing the rotation torque of the auxiliary moving valve plate 131.

[0271] In some cases, the auxiliary static valve plate 132 is also provided with an auxiliary valve drain hole 1321. The auxiliary valve drain hole 1321 can be connected through the auxiliary valve first groove 1311 and the softening connection hole 1322 to discharge the water in the softening device 190 through the auxiliary valve drain hole 1321.

[0272] In some cases, the auxiliary valve plate 131 is also provided with a secondary valve second groove 1312. The secondary valve second groove 1312 is a process groove. Under the premise of satisfying the structural strength of the auxiliary valve plate 131, the secondary valve second groove 1312 can be opened to avoid the positions of the secondary valve first groove 1311, the secondary valve third groove 1313 and the secondary valve inlet 1314, which can reduce the contact area between the auxiliary valve plate 131 and the secondary stationary valve plate 132.

[0273] The auxiliary stationary valve plate has multiple auxiliary valve through holes, and the auxiliary moving valve plate has multiple auxiliary valve grooves. The orthogonal projection of the auxiliary valve through holes onto the auxiliary moving valve plate is located within the auxiliary valve grooves.

[0274] The various valve through holes of the auxiliary valve plate 132 are located in the auxiliary valve groove (the auxiliary valve groove includes the auxiliary valve first groove body 1311, the auxiliary valve second groove body 1312 or the auxiliary valve third groove body 1313) of the auxiliary moving valve plate 131 in the orthographic projection of the auxiliary moving valve plate 131, and the sealing performance of the various valve through holes is ensured.

The main valve sealing member 127 is arranged between the main static valve plate 122 and the inner wall of the main cavity 111, and the auxiliary valve sealing member 1392 is arranged between the auxiliary static valve plate 132 and the inner wall of the auxiliary cavity 112, so as to avoid leakage between adjacent openings and prevent water from mixing between different holes. The main static valve plate 122 and the auxiliary static valve plate 132 are also designed with fixing grooves or hole positions for fixing with the valve shell 110.

The difference between the two cavities is that the hole structures, the number and the position are different, i.e., the functions of the main cavity 111 and the auxiliary cavity 112 are different. The two cavity structures are circular structures, and the left and right cavities are horizontally arranged. The axial direction of the cavity (the direction of the rotating axis of the valve assembly) is horizontal, and the resin tank connected to the bottom is vertically distributed. Correspondingly, the resin tank is vertically placed in the water softener.
