There are a large number of calcium and magnesium ions in the water used by residents, and long-term use of hard water has certain harm to the body. For example, if clothes are washed with hard water for a long time, the clothes will turn yellow and lack luster. The water pipeline for residents will be blocked by scale, and some heating equipment will be affected by scale, which will affect the heat exchange efficiency and damage the equipment over a long period of time. Reducing or removing calcium and magnesium ions in water, so that hard water becomes soft water, has many benefits for people's life, such as taking a bath with soft water, which does not dry the skin, and using soft water for skin care, which makes the skin smoother.

[0094] Embodiments of the present application, with reference to Figures 1 to 43 As shown, 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.

[0095] With reference to Figures 1 to 6 and Figure 43 As shown, the embodiments of the present application provide a soft water valve, which comprises a valve shell 110, a main valve assembly 120 and a secondary valve assembly 130, the valve shell 110 comprises a main cavity 111 and a secondary cavity 112, by adjusting the on-off of the flow passage corresponding to the main valve assembly 120, adjusting the on-off of the flow passage corresponding to 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.

[0096] The switchable function modes of the soft water valve include a water production mode, a water injection mode, a salt absorption mode, and a cleaning mode. In the water production mode, raw water can be fed to the softening device 190 through the soft water valve, the soft water obtained by the softening device 190 is fed back to the soft water valve, and the user can obtain 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 200 can be raw water or soft water, so that the water dissolves the salt in the salt tank 200. 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, which can be referred to as a salt melting mode. In the salt absorption mode, the salt water in the salt tank 200 is fed to the softening device 190 through the soft water valve, and the water that has cleaned the softening device 190 is discharged through the soft water valve. In the cleaning mode, raw water is fed to the softening device 190 through the soft water valve, and the water that has cleaned the softening device 190 is discharged through the soft water valve. The cleaning mode includes at least one of a backwashing mode and a forward washing mode. In the backwashing mode, raw water is fed into the softening device 190 through the soft water inlet 119 and discharged to the soft water valve through the raw water outlet 118. In the forward washing mode, raw water is fed into the softening device 190 through the raw water outlet 118 and discharged to the soft water valve through the soft water inlet 119.

[0097] It should be noted that the raw water can be understood as water fed through the raw water inlet 113 of the soft water 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 raw water.

[0098] Reference Figures 2 to 6 , Figures 9 to 14 and Figure 21As shown, the valve housing 110 includes a raw water inlet 113, a softened water outlet 114, a main cavity 111, a secondary cavity 112, a raw water outlet 118 and a softened water inlet 119. The raw water inlet 113 is used to connect with a raw water pipe to make raw water enter into the valve housing 110 of the water softener 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, raw water can flow into at least one of the main cavity 111 and the secondary cavity 112, and then pass through the corresponding valve assembly to regulate the flow direction of the raw water. The raw water outlet 118 and the raw water inlet 113 can be adjusted by the main valve assembly 120 to be connected or disconnected, when the main valve assembly 120 connects the raw water inlet 113 and the raw water outlet 118, raw water can be sent to the softening device 190 through the raw water outlet 118, based on the fact that the raw water outlet 118 and the softened water inlet 119 can be communicated through the softening device 190, after the raw water is softened in the softening device 190, the softened water in the softening device 190 can be sent to the water softener valve through the softened water inlet 119, and the softened water inlet 119 is communicated with the softened water outlet 114 to send the softened water out of the water softener valve. Of course, the softened water inlet 119 can also be adjusted to be connected or disconnected with the flow channel inside the secondary valve assembly 130 to regulate the flow direction of the softened water.

[0099] It can be understood that the main cavity 111 and the raw water outlet 118 are always connected, in the case that the main cavity 111 is filled with water, water can flow to the softening device through the raw water outlet 118, and in the case that the main cavity 111 is not filled with water, the raw water outlet 118 stops sending water to the softening device, without the need to regulate the connection or disconnection of the main cavity 111 and the raw water outlet 118, the structure of the main valve core 124 can be simplified. Raw water enters the valve housing 110 through the raw water inlet 113, and then the flow direction of the raw water is controlled by the main valve assembly 120, so that the raw water flows to the main cavity 111 or the secondary cavity 112. When the raw water flows to the main cavity 111, the raw water can flow into the softening device 190 from the raw water outlet 118, and when the raw water flows to the secondary cavity 112, at least part of the raw water can flow to the softened water outlet 114 and be discharged from the water softener valve. Of course, the main cavity 111 and the raw water outlet 118 can also be adjusted to be connected or disconnected by the main valve core 124 (not shown in the figure).

[0100] For example, the main cavity 111 is provided with a main cavity communication hole 116, the main cavity communication hole 116 is communicated with the raw water outlet 118, so that the main cavity 111 and the raw water outlet 118 are connected, so that the water in the main cavity 111 can flow to the raw water outlet 118 through the main cavity communication hole 116, or the water at the raw water outlet 118 can flow into the main cavity 111 through the main cavity communication hole 116.

[0101] The auxiliary cavity 112 and the soft water outlet 114 are in communication. It can be understood that the auxiliary cavity 112 and the soft water outlet 114 are always in communication. In the case that water is supplied to the auxiliary cavity 112, the user can take water in the auxiliary cavity 112 through the soft water outlet 114, which can be raw water or soft water. In the case that water is not supplied to the auxiliary cavity 112, the user cannot take water in the auxiliary cavity 112. The water in the auxiliary cavity 112 can also be delivered to the salt tank 200 or the softening device 190 through the auxiliary valve core 134. According to the technical scheme of the present application, the auxiliary cavity 112 is kept supplied with water, so that the user can continuously take water from the auxiliary cavity 112, achieving the purpose of 24-hour water use.

[0102] For example, the auxiliary cavity 112 is provided with an auxiliary cavity communication hole 1111, which is in communication with the soft water outlet 114, so that the water in the auxiliary cavity 112 can flow along the auxiliary cavity communication hole 1111 and the soft water outlet 114. That is, the water obtained by the user at the soft water outlet 114 is the same kind of water as the water in the auxiliary cavity 112. Through the cooperation of the main valve assembly 120 and the auxiliary valve assembly 130, the water in the auxiliary cavity 112 can be used in the water production mode, the water filling mode, the salt sucking mode and the cleaning mode. For example, in the water production mode and the water filling mode, the water in the auxiliary cavity 112 is soft water, and in the salt sucking mode, the water in the auxiliary cavity 112 is raw water, so that the user can use water in any mode.

[0103] For example, the valve housing 110 is configured with a water outlet flow channel 1112, which is in communication with the auxiliary cavity communication hole 1111 and the soft water outlet 114, so that the water in the auxiliary cavity 112 can flow along the auxiliary cavity communication hole 1111, the water outlet flow channel 1112 and the soft water outlet 114.

[0104] It should be noted that the water outlet flow channel 1112 can be directly in communication with the soft water outlet 114, or the water outlet flow channel 1112 can be in communication with the soft water outlet 114 through a corresponding passage.

[0105] The valve housing 110 is configured with a soft water passage, which is in communication with the auxiliary cavity 112 and the soft water outlet 114, so that the water in the auxiliary cavity 112 can flow along the soft water passage to the soft water outlet 114.

[0106] It can be understood that the soft water passage can be in communication with the auxiliary cavity 112 through the water outlet flow channel 1112, so that the water in the auxiliary cavity 112 can flow along the water outlet flow channel 1112 and the soft water passage to the soft water outlet 114.

[0107] For example, the valve housing 110 is connected with a flow meter 150, and the detection part of the flow meter 150 is located in the soft water passage. The flow meter 150 can detect the flow of water flowing through the soft water passage.

[0108] The valve housing 110 is configured with a raw water channel, one end of the raw water channel is formed with a raw water inlet 113, and the other end of the raw water channel is in communication with at least one of the main cavity 111 and the auxiliary cavity 112, so that raw water can flow into at least one of the main cavity 111 and the auxiliary cavity 112.

[0109] It can be understood that the main valve assembly 120 is located at the other end of the raw water channel, so that the raw water is first delivered to the main valve assembly 120, and the main valve assembly 120 has at least two flow paths, one of which is used to communicate the other end of the raw water channel and the main cavity 111, and the other of which is used to communicate the other end of the raw water channel and the auxiliary cavity 112. By controlling the opening and closing of the two flow paths through the main valve assembly 120, the opening and closing control of the raw water inlet 113 and the main cavity 111 can be realized, and the opening and closing control between the raw water inlet 113 and the auxiliary cavity 112 can also be realized.

[0110] The valve housing 110 is configured with a communication channel 1113, the outlet of the communication channel 1113 is in communication with the auxiliary cavity 112, and the inlet of the communication channel 1113 is in communication with the raw water inlet 113. That is, the inlet of the communication channel 1113 can be in communication with the raw water inlet 113, or the inlet of the communication channel 1113 can be disconnected from the raw water inlet 113. When the inlet of the communication channel 1113 is in communication with the raw water inlet 113, raw water enters the valve housing 110 through the raw water inlet 113, and then the raw water enters the auxiliary cavity 112 through the communication channel 1113. When the inlet of the communication channel 1113 is disconnected from the raw water inlet 113, it means that the raw water cannot flow directly to the auxiliary cavity 112.

[0111] Exemplarily, the inlet of the communication channel 1113 is in communication with the raw water inlet 113 through the main valve assembly 120. Since the main valve assembly 120 is located between the raw water inlet 113 and the communication channel 1113, the opening and closing control of the raw water inlet 113 and the inlet of the communication channel 1113 can be realized through the main valve assembly 120.

[0112] Of course, the outlet of the communication channel 1113 can also be in communication with the auxiliary cavity 112 (not shown in the figure), and the auxiliary valve assembly 130 adjusts the opening and closing of the auxiliary cavity 112 and the communication channel 1113. At this time, the communication channel 1113 and the raw water inlet 113 can be always in communication or in communication through the main valve assembly 120. The communication channel 1113 can also be in communication with the main cavity 111 through the main valve assembly 120. In the case that the main cavity 111 is in communication with the raw water inlet 113, the main valve assembly 120 adjusts the opening and closing of the main cavity 111 and the auxiliary cavity 112, that is, the main valve assembly 120 can control the main cavity 111 and the auxiliary cavity 112 to be in communication with the raw water inlet 113, or the main valve assembly 120 makes the raw water inlet 113 simultaneously in communication with the main cavity 111 and the auxiliary cavity 112.

[0113] Reference Figure 2 and Figure 3As shown, the inlet of the communication passage 1113 is located at the bottom of the main cavity 111, and the inlet of the communication passage 1113 corresponds to the main auxiliary connecting hole 1223 of the main valve sheet 122. The water inlet of the communication passage 1113 is mainly controlled by the main valve core 124 located in the main cavity 111. The main valve sheet 121 can actively control whether the raw water can flow into the auxiliary cavity 112. The communication passage 1113 between the two cavities is designed to be controllable, mainly to ensure that the user can use water during the regeneration process of the softening material of the water softener, and will not affect the regeneration of the softening material. The outlet of the communication passage 1113 communicates with the auxiliary cavity 112. The auxiliary cavity water inlet hole is opened in the side wall of the auxiliary cavity 112. The outlet of the communication passage 1113 is the auxiliary cavity water inlet hole, so as to form a channel connecting the two cavities.

[0114] The outlet end of the communication passage 1113 communicates with the auxiliary communication port of the auxiliary cavity 112, and the inlet end of the communication passage 1113 communicates with the main communication port of the main cavity 111. The main communication port communicates with the raw water inlet 113 through the main valve core 124, so that the water softener can be switched between the state that the raw water inlet 113 communicates with the main communication port and the state that the raw water inlet 113 is disconnected from the main communication port. That is, the main valve core 124 can control the on-off connection between the raw water inlet 113 and the communication passage 1113, and the communication passage 1113 can communicate with the auxiliary cavity 112 through the auxiliary communication port, so that the main valve core 124 can control the on-off connection between the raw water inlet 113 and the auxiliary cavity 112.

[0115] The auxiliary communication port can be connected to the raw water inlet 113 through the auxiliary valve core 134, so that the water softener can be switched between the state that the raw water inlet 113 communicates with the auxiliary communication port and the state that the raw water inlet 113 is disconnected from the auxiliary communication port. That is, the on-off connection between the raw water inlet 113 and the auxiliary cavity 112 can be controlled.

[0116] The outlet of the communication passage 1113 is formed in the wall surface of the auxiliary cavity 112. The outlet of the communication passage 1113 and the auxiliary cavity communication hole 1111 are located on the same side of the auxiliary valve core 134. When the communication passage 1113 communicates with the raw water inlet 113, the raw water can flow directly to the auxiliary cavity communication hole 1111 through the raw water inlet 113 and the communication passage 1113, and then flow to the soft water outlet 114 through the auxiliary cavity communication hole 1111, without passing through the auxiliary valve core 134, thereby simplifying the structure of the auxiliary valve core 134.

[0117] The outlet of the communication passage 1113 and the soft water inlet 119 are located on the two sides of the auxiliary valve core 134, respectively, so as to facilitate the auxiliary valve core 134 to control the on-off connection between the outlet of the communication passage 1113 and the soft water inlet 119. The auxiliary valve core 134 can separate the outlet of the communication passage 1113 and the soft water inlet 119.

[0118] It should be noted that "two sides" in "two sides of the auxiliary valve core 134" refers to two positions separated by the auxiliary valve core 134, i.e. "two sides" refers to relationships including but not limited to front and back, left and right, and up and down.

[0119] The outlet of the communication channel 1113 is higher than the auxiliary cavity communication hole 1111, so that when raw water flows to the auxiliary cavity communication hole 1111 through the communication channel 1113, the raw water can flow to the soft water outlet 114 through the auxiliary cavity communication hole 1111, avoiding the problem of water accumulation in the auxiliary cavity 112 caused by the outlet of the communication channel 1113 being lower than the auxiliary cavity communication hole 1111.

[0120] Based on the state that the soft water valve is in communication between the auxiliary cavity 112 and the raw water inlet 113, the auxiliary valve water inlet 1314 is in corresponding communication with the auxiliary communication hole. The auxiliary valve water inlet 1314 is in communication with the auxiliary cavity 112, and when raw water flows into the auxiliary cavity 112 through the raw water inlet 113 and the auxiliary communication hole, the raw water can directly flow into the auxiliary cavity 112, and the auxiliary valve core will not block the flow of raw water into the auxiliary cavity 112, so that the raw water can flow smoothly into the auxiliary cavity 112.

[0121] Specifically, the main driving part 125 is used to drive the main valve core 124 to switch between the third main valve position in which the main valve core 124 communicates the inlet of the communication channel 1113 and the raw water inlet 113 and the first main valve position in which the main valve core 124 communicates the main cavity 111 and the raw water inlet 113.

[0122] It can be understood that by driving the main valve core 124 to switch between the first main valve position and the third main valve position through the main driving part 125, when the main valve core 124 is in the first main valve position, the main valve core 124 communicates the main cavity 111 and the raw water inlet 113, and at the same time, the main valve core 124 blocks the raw water inlet 113 and the inlet of the communication channel 1113, so that the raw water flows into the main cavity 111, at this time, the soft water valve is in the water making mode or the water filling mode or the forward washing mode. When the main valve core 124 is in the third main valve position, the main valve core 124 communicates the inlet of the communication channel 1113 and the raw water inlet 113, so that the raw water flows into the auxiliary cavity 112 through the raw water inlet 113 and the communication channel 1113, and at this time, the main valve core 124 blocks the raw water inlet 113 and the main cavity 111, at this time, the soft water valve is in the salt suction mode or the reverse washing mode.

[0123] That is, when the cleaning mode includes the forward cleaning mode and the reverse cleaning mode, in the water production mode, the water injection mode and the forward cleaning mode, the main valve core 124 is in the first main valve position, the communication flow channel 128 is disconnected, the raw water inlet 113 is communicated with the main cavity 111, at this time the main valve assembly 120 is mainly used to transport raw water to the main cavity 111, so that the raw water enters the softening device 190, at this time the auxiliary valve assembly 130 is switched through the flow path, so that the soft water valve is switched between the water production mode, the water injection mode and the forward cleaning mode; in the salt suction mode and the reverse cleaning mode, the communication flow channel 128 is communicated, the raw water inlet 113 is disconnected with the main cavity 111, at this time the main valve assembly 120 is mainly used to transport the softening device 190 to the sewage discharge valve shell 110 of the raw water outlet 118, at this time the auxiliary valve assembly 130 is switched through the flow path, so that the soft water valve is switched between the salt suction mode and the reverse cleaning mode.

[0124] It should be noted that in the salt suction mode and the reverse cleaning mode, the main valve core 124 is driven to be in the third main valve position, so that the communication passage 1113 communicates the raw water inlet 113 and the auxiliary cavity 112, so that the raw water inlet 113, the communication passage 1113 and the auxiliary cavity 112 are communicated. The raw water can flow to the auxiliary cavity 112 through the raw water inlet 113 and the communication passage 1113, and then the soft water valve is switched between the salt suction mode and the reverse cleaning mode through the flow path switching of the auxiliary valve assembly 130, but no matter how the auxiliary valve assembly 130 is switched, the raw water needs to flow into the auxiliary cavity 112 first, and the auxiliary cavity 112 is communicated with the soft water outlet 114, so that in the salt suction mode and the reverse cleaning mode, the water at the soft water outlet 114 is raw water, which ensures that the user has water available in the salt suction mode and the reverse cleaning mode.

[0125] Among them, in the third main valve position, the main valve core 124 is driven by the main driving part 125, so that the communication flow channel 128 of the main valve core 124 is communicated, the inlet of the communication passage 1113 and the raw water inlet 113 are communicated through the communication flow channel 128, so that the raw water inlet 113, the communication flow channel 128, the communication passage 1113 and the auxiliary cavity 112 are communicated. The inlet of the communication passage 1113 and the raw water inlet 113 are communicated through the communication flow channel 128, so that the water can flow along the path of the raw water inlet 113, the communication flow channel 128, the communication passage 1113 and the auxiliary cavity 112. The inlet of the communication passage 1113 and the raw water inlet 113 are connected through the communication flow channel 128, the communication flow channel 128 is disconnected when the main valve core 124 rotates to the first main valve position, so that the inlet of the communication passage 1113 and the raw water inlet 113 are disconnected, and the communication flow channel 128 is communicated when the main valve core 124 rotates to the third main valve position, so that the inlet of the communication passage 1113 and the raw water inlet 113 are communicated.

[0126] For example, the inlet of the communication flow channel 128 is in communication with the raw water inlet 113, the outlet of the communication flow channel 128 is in communication with the inlet of the communication channel 1113, the inlet of the communication flow channel 128 is towards the raw water inlet 113, that is, the inlet of the communication flow channel 128 is not in communication with the main cavity 111 at this time, the raw water flows through the raw water inlet 113, the inlet of the communication flow channel 128, the communication flow channel 128, the communication channel 1113 and the auxiliary cavity 112, and the raw water does not need to pass through the main cavity 111, so that the main cavity 111 and the raw water inlet 113 can be separated, and it is ensured that the raw water cannot enter the main cavity 111 when the main valve is in the third position.

[0127] For example, the main valve water inlet hole 1221 of the main static valve piece 122 is in communication with the main valve first groove 1212 of the main driving valve piece 121 and the main auxiliary connecting hole 1223 of the main static valve piece 122 to form a communication flow channel 128, the main auxiliary connecting hole 1223 is in communication with the inlet of the communication channel 1113, the inlet of the communication flow channel 128 is formed in the main valve water inlet hole 1221, and the outlet of the communication flow channel 128 is formed in the main auxiliary connecting hole 1223. By driving the main driving valve piece 121 to rotate to the third main valve position through the main driving part 125, the main valve first groove 1212 is in communication with the main valve water inlet hole 1221 and the main auxiliary connecting hole 1223, so that the main valve water inlet hole 1221, the main valve first groove 1212 and the main auxiliary connecting hole 1223 are in communication to form a communication flow channel 128, and the raw water can flow along the path of the raw water inlet 113, the main valve water inlet hole 1221, the main valve first groove 1212, the main auxiliary connecting hole 1223, the communication channel 1113 and the auxiliary cavity 112.

[0128] For example, in the salt suction mode and the backwashing mode, the main valve water inlet hole 1221 includes a first region and a second region in communication, the first region is in communication through the main valve first groove 1212 and the main auxiliary connecting hole 1223, and the second region is closed through the main valve process groove of the main driving valve piece 121. So that the raw water flows to the auxiliary cavity through the first region, the main valve first groove 1212 and the main auxiliary connecting hole 1223.

[0129] For example, the main valve water inlet hole 1221 can be in normal communication with the raw water inlet 113, the on-off control of the communication flow channel 128 can be realized by driving the main driving valve piece 121 to rotate through the main driving part 125, and the structure of the main valve assembly 120 can be simplified.

[0130] Referring to FIGS. 1 to 5, Figure 7 , Figure 8 , Figure 36 and Figure 40 , the main valve assembly 120 includes a main valve core 124 and a main driving part 125 for driving the main valve core 124 to move, the main valve core 124 is located in the main cavity 111, and the main cavity 111 and the raw water inlet 113 can be switched between communication and disconnection through the main valve core 124.

[0131] In some cases, the communication between the secondary chamber 112 and the raw water inlet 113 is regulated by the main valve core 124, so that the communication between the secondary chamber 112 and the raw water inlet 113 can be switched between being connected and being disconnected. When the secondary chamber 112 is connected to the raw water inlet 113, raw water enters the secondary chamber 112, and then the flow direction of water is regulated by the secondary valve assembly 130. When the secondary chamber 112 is disconnected from the raw water inlet 113, raw water flows into the main chamber 111 through the main valve core 124, and then the flow direction of water is regulated by the cooperation of the secondary valve assembly 130 and the secondary chamber 112.

[0132] The secondary valve assembly 130 includes a secondary valve core 134 and a secondary driving part 135 for driving the secondary valve core 134 to move. The secondary valve core 134 is located in the secondary chamber 112, and regulates the communication of the flow passage of the secondary valve core 134. The secondary valve core 134 can regulate the communication between the soft water inlet 119 and the corresponding passage in the secondary valve core 134, and can also regulate the communication between the secondary chamber 112 and the corresponding passage in the secondary valve core 134. For example, the secondary valve core 134 can regulate the communication between the soft water inlet 119 and the secondary chamber 112, the communication between the secondary chamber 112 and the salt tank connecting port 1110 of the valve housing 110, and the communication between the soft water inlet 119 and the jet 160 of the soft water valve. The secondary chamber 112 and the secondary valve assembly 130 are mainly used to regenerate the softening material in the softening device 190 (the regeneration process includes a water injection mode, a salt suction mode, and a cleaning mode). The secondary chamber 112 and the secondary valve assembly 130 are also used to continuously supply water to the soft water outlet 114.

[0133] The main driving part 125 can drive the main valve core 124 to move, and the secondary driving part 135 can drive the secondary valve core 134 to move, so that the water valve can be switched between the water production mode, the water injection mode, the salt suction mode, and the cleaning mode.

[0134] The main cavity 111 cooperates with the main valve assembly 120 to mainly send water to the softening device 190, and the main cavity 111 cooperates with the main valve assembly 120 to mainly control normal water production. Since the normal water production flow is relatively large, the main cavity 111 and the main valve core 124 are used for water production with a large opening structure. At this time, the auxiliary valve core 134 is used to connect the soft water inlet 119 and the auxiliary cavity 112. The auxiliary cavity 112 cooperates with the auxiliary valve assembly 130 to mainly send the soft water of the softening device 190 to the auxiliary cavity 112, and is used for various modes requiring soft water. The auxiliary cavity 112 and the auxiliary valve core 134 have a large opening structure for the user to take water. Since the water softener also has other state functions, such as forward washing, backwashing, water injection, salt suction slow washing, etc., the flow requirement of these states is relatively small, so the opening area of the hole for water injection and salt suction in the auxiliary valve core 134 can be smaller than that of the hole for water inlet. Therefore, 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 play an auxiliary function. The auxiliary cavity 112 cooperates with the auxiliary valve assembly 130 to mainly control other flow paths, and the main cavity 111 cooperates with the main valve assembly 120 to increase the flow of water sent to the softening device 190. The auxiliary cavity 112 cooperates with the main cavity 111 to perform other functions.

[0135] The function of the main cavity 111 cooperating with the main valve assembly 120 is mainly normal water production. Since the raw water flow demand of the water production mode is relatively large, the main valve core 124 forms the main water production flow channel 126, the main water production flow channel 126 connects the main cavity 111 and the raw water inlet 113, the main cavity 111 and the raw water outlet 118 are connected, and the main valve core 124 is used for water production with a large opening structure. In the water production mode, the auxiliary valve core 134 forms the auxiliary water production flow channel 136, the soft water inlet 119 is connected to the auxiliary cavity 112 through the auxiliary water production flow channel 136, the soft water outlet 114 is connected to the auxiliary cavity 112, and the auxiliary valve core 134 is used for water taking with a large opening structure.

[0136] Since the water softener also has other state functions, such as cleaning, water injection, salt suction slow washing, etc., the flow requirement of these states is relatively small, so the auxiliary valve core 134 can form multiple flow channels, and the flow area required by the flow channel formed by the auxiliary valve core 134 is 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 control the pollution in these regeneration processes. 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, and the flow area of the flow channel formed by the auxiliary cavity 112 and the auxiliary valve assembly 130 is smaller than the flow area of the main water production flow channel 126 formed by the main cavity 111 and the main valve assembly 120.

[0137] As described above, at least one of the main cavity 111 and the auxiliary cavity 112 can be in communication with the raw water inlet 113. It can be understood that at least one of the main cavity 111 and the auxiliary cavity 112 is supplied with raw water, and the raw water is supplied 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 in communication 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 in communication with the raw water inlet 113, the main cavity 111 and the auxiliary cavity 112 can be in communication with the raw water inlet 113 through independent channels. Alternatively, one of the main cavity 111 and the auxiliary cavity 112 can be in communication with the raw water inlet 113 through a channel, and the main cavity 111 and the auxiliary cavity 112 can be in communication through a communication channel 1113.

[0138] 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 the soft water machine in different states. Through water path switching of the main valve assembly 120 and the auxiliary valve assembly 130, water path adjustment of the soft water machine in different states, that is, water path function requirements in multiple states such as water production mode, cleaning mode (at least one of forward cleaning and reverse cleaning), water injection mode, and salt suction slow cleaning mode (hereinafter referred to as salt suction mode) can be realized. The entire valve head structure is compact, simple, has high reliability, and is stable and good in work.

[0139] Referring to Figures 1 to 6 and Figures 40 to 42 As shown in the drawings, the valve housing 110 of the soft water valve is further provided with a sewage outlet 115 and a salt tank connecting port 1110. The sewage outlet 115 is used for discharging sewage, and can be in communication with the flow channel of at least one of the main cavity 111 and the auxiliary cavity 112 to realize sewage discharge in 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 soft water valve. The salt tank connecting port 1110 can have at least one of the functions of water injection and salt suction. One of the main valve assembly 120 and the auxiliary valve assembly 130 can be used for on-off adjustment of the salt tank connecting port 1110 to realize on-off connection between the soft water valve and the salt tank 200.

[0140] The valve housing 110 is formed with a sewage channel 1114, which can be in communication with at least one of the main cavity 111 and the auxiliary cavity 112 to realize sewage discharge in different flow paths. For example, one end of the sewage channel 1114 is in communication with at least one of the main cavity 111 and the auxiliary cavity 112, and the other end of the sewage channel 1114 forms the sewage outlet 115, so that the sewage in the valve housing 110 can be discharged through the sewage channel 1114 and the sewage outlet 115.

[0141] In some cases, referring toFigure 7 and Figure 8 As shown, 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 be switched at multiple positions, and after switching, multiple flow paths can be adjusted for on / off.

[0142] For example, the main valve assembly 120 can switch between at least two main valve positions. In one main valve position, the main valve assembly 120 connects the main chamber 111 to the raw water inlet 113 for supplying water to the softening device 190. In this position, the softening valve corresponds to the water production mode and the water injection mode. In another main valve position, the main valve assembly 120 connects the raw water outlet 118 to the drain outlet 115 for wastewater discharge. In this position, the softening valve corresponds to the backwash mode and the brine suction mode. In yet another main valve position, the main valve assembly 120 can also connect the secondary chamber 112 to the raw water inlet 113. The secondary valve assembly 130 can switch between multiple secondary valve positions (e.g., three, four, five, etc.), with each secondary valve position corresponding to a different softening valve mode. The secondary valve assembly 130 can also switch between three secondary valve positions (not shown in the figure). These secondary valve positions are mainly used for cleaning and coordinating with the water injection and brine suction modes. The main valve assembly 120 and the auxiliary valve assembly 130 have various structures, and their functions and structures can be set as needed.

[0143] In some cases, refer to Figure 7 , Figure 8 and Figure 40 As shown, the main drive unit 125 of the main valve assembly 120 is used to drive the main valve core 124 to rotate, and the main valve core 124 switches between multiple main valve positions by rotation. And / or, the secondary drive unit 135 of the secondary valve assembly 130 is used to drive the secondary valve core 134 to rotate, and the secondary valve core 134 switches between multiple secondary valve positions by rotation.

[0144] 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, and both the valve discs of the main valve core 124 and the auxiliary valve core 134 can be ceramic discs. (Reference) Figure 7 As shown, when the main valve assembly 120 is a disc valve, the main valve core 124 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 125 is connected to the driving valve disc 121. The main drive unit 125 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 8As shown, when the sub-valve assembly 130 is a disc valve, the sub-valve core 134 includes a sub-static valve disc 132 and a sub-moving valve disc 131, the sub-static valve disc 132 is fixed in the sub-cavity 112, and the sub-driving part 135 is connected to the sub-moving valve disc 131, and the sub-driving part 135 is used to drive the sub-moving valve disc 131 to rotate relative to the sub-static valve disc 132, so as to adjust the opening and closing of the corresponding flow passage of the sub-valve assembly 130.

[0145] In the disc valve, when the valve disc is a porcelain disc, the service life and reliability of the disc valve are higher due to the good wear resistance of the porcelain disc. Compared with the case that the plunger valve has high requirements for structural machining precision, the manufacturing cost of the disc valve is reduced, which is an important direction for the development of soft water valves.

[0146] For example, the main moving valve disc 121 is provided with at least one notch structure or groove structure, the main static valve disc 122 is provided with at least one hole structure, so that the main valve core 124 has at least one flow passage. When the main valve core 124 has at least two flow passages, the main moving valve disc 121 can be driven to rotate by the main driving part 125, so that the main moving valve disc 121 and the main static valve disc 122 form different flow passages.

[0147] For example, the side of the main moving valve disc 121 in contact with the main static valve disc 122 is distributed in a large fan shape, and the side edge has a large main valve water inlet 1211 which is also distributed in a fan shape. The main static valve disc 122 is provided with a main valve water inlet hole 1221, and the water in the raw water inlet 113 can enter the main cavity 111 through the main valve water inlet hole 1221 of the main static valve disc 122 and the main valve water inlet 1211 of the main moving valve disc 121. Meanwhile, the main moving valve disc 121 is also designed with two groove bodies, and by rotating the main moving valve disc 121, the groove bodies of the main moving valve disc 121 can connect or disconnect the main valve blowdown hole 1222 of the main static valve disc 122 and the main cavity 111, so as to realize the connection or disconnection of the corresponding flow passage. The flow area of the main valve water inlet hole 1221 and the main valve water inlet 1211 is large, which is mainly used for water production, and the flow area of the main valve blowdown hole 1222 is small, which can reduce the blowdown flow.

[0148] In some cases, when the sub-cavity 112 is connected or disconnected with the raw water inlet 113 through the main valve core 124, the main static valve disc 122 is also provided with a main-sub connection hole 1223 which connects the sub-cavity 112, and the main moving valve disc 121 is provided with a main valve first groove 1212 which can connect the main-sub connection hole 1223 and the main valve water inlet hole 1221, so as to form a connected flow passage 128.

[0149] Reference Figures 16 to 30As shown, in some cases, the main valve core 124 has a main water production flow channel 126, a communication flow channel 128, and a first blowdown flow channel 127, etc. The main water inlet 1211 of the main active valve piece 121 and the main water inlet hole 1221 of the main passive valve piece 122 are communicated to form the main water production flow channel 126, at this time, the main valve core 124 is in the first main valve position, and the water softener valve can be in the water production mode or the water filling mode or the forward washing mode; the main water inlet hole 1221 of the main passive valve piece 122 is communicated through the main valve first groove 1212 of the main active valve piece 121 and the main auxiliary connecting hole 1223 of the main passive valve piece 122 to form the communication flow channel 128, at this time, the main valve core 124 is in the third main valve position, and the water softener valve can be in the salt suction mode or the reverse washing mode; the main valve blowdown hole 1222 of the main passive valve piece 122 and the main water inlet 1211 of the main active valve piece 121 are communicated to form the first blowdown flow channel 127, at this time, the main valve core 124 is in the third main valve position, and the water softener valve is in the salt suction mode or the reverse washing mode.

[0150] For example, the auxiliary valve core 134 has at least one flow channel, the auxiliary active valve piece 131 is provided with at least one notch structure or groove structure, and the auxiliary passive valve piece 132 has at least one hole structure, so that the auxiliary valve core 134 has at least one flow channel. When the auxiliary valve core 134 has at least two flow channels, the auxiliary active valve piece 131 can be driven to rotate by the auxiliary driving part 135, so that the auxiliary active valve piece 131 and the auxiliary passive valve piece 132 form different flow channels.

[0151] In some cases, the sub-valve core 134 has a sub-water production flow path 136, a water injection flow path 137, a forward washing flow path 138, a backwashing flow path, a first salt suction flow path 1341 and a second salt suction flow path 1342. The softened connection hole 1322 of the sub-static valve piece 132 and the sub-valve water inlet 1314 of the sub-moving valve piece 131 are communicated to form the sub-water production flow path 136 when the sub-valve core 134 is in the first sub-valve position, and the water softener is in the water production mode. The softened connection hole 1322 of the sub-static valve piece 132 and the salt injection water hole 1324 of the sub-static valve piece 132 are communicated to form the water injection flow path 137, such as the softened connection hole 1322 and the salt injection water hole 1324 can be communicated through the sub-valve water inlet 1314 of the sub-moving valve piece 131, when the sub-valve core 134 is in the second sub-valve position, and the water softener is in the water injection mode. The softened connection hole 1322 of the sub-static valve piece 132 and the sub-valve blowdown hole 1321 of the sub-static valve piece 132 are communicated to form the forward washing flow path 138, such as the sub-valve blowdown hole 1321 can be communicated with the softened connection hole 1322 through the sub-valve water inlet 1314 of the sub-moving valve piece 131, when the sub-valve core 134 is in the fourth sub-valve position, and the water softener is in the forward washing mode. The softened connection hole 1322 of the sub-static valve piece 132 and the sub-valve water inlet 1314 of the sub-moving valve piece 131 are communicated to form the backwashing flow path, when the sub-valve core 134 is in the first sub-valve position, and the water softener is in the backwashing mode. The sub-valve water inlet 1314 of the sub-moving valve piece 131 and the salt injection water hole 1324 of the sub-static valve piece 132 are communicated to form the first salt suction flow path 1341, and the salt water hole 1323 of the sub-static valve piece 132 is communicated through the first sub-valve groove 1311 of the sub-moving valve piece 131 and the softened connection hole 1322 of the sub-static valve piece 132 to form the second salt suction flow path 1342, when the sub-valve core 134 is in the third sub-valve position, and the water softener is in the salt suction mode.

[0152] It should be noted that in the water production mode and the backwashing mode, the sub-valve core 134 is in the first sub-valve position, and the communication modes of the sub-valve core 134, the sub-cavity 112 and the softening device 190 are the same, but the flow directions of water are different.

[0153] Of course, in some cases, the main valve assembly 120 and the sub-valve assembly 130 can also switch the flow path on-off through other ways, such as one of the main valve assembly 120 and the sub-valve assembly 130 is moved to realize the flow path switching, and one of the main valve assembly 120 and the sub-valve assembly 130 can be a plunger valve.

[0154] In some cases, referring to Figure 36As shown, the main driving part 125 includes a main valve motor and a main shaft assembly 1251, one end of the main shaft assembly 1251 is connected to the main valve motor, and the other end is connected to the main movable valve plate 121. The main valve motor drives the main valve motor to rotate through the main shaft assembly 1251, and the main valve motor can drive the main movable valve plate 121 to rotate, so that the relative position between the main movable valve plate 121 and the main static valve plate 122 changes, and the main valve core 124 forms different flow channels.

[0155] In some cases, reference Figure 36 As shown, the auxiliary driving part 135 includes an auxiliary valve motor and an auxiliary shaft assembly 1351, one end of the auxiliary shaft assembly 1351 is connected to the auxiliary valve motor, and the other end is connected to the auxiliary movable valve plate 131. The auxiliary valve motor drives the auxiliary valve motor to rotate through the auxiliary shaft assembly 1351, and the auxiliary valve motor can drive the auxiliary movable valve plate 131 to rotate, so that the relative position between the auxiliary movable valve plate 131 and the auxiliary static valve plate 132 changes, and the auxiliary valve core 134 forms different flow channels.

[0156] It should be noted that the main driving part 125 and the auxiliary driving part 135 can also share a driving motor, and are not limited to the above-mentioned main valve motor and auxiliary valve motor.

[0157] Next, reference Figures 9 to 30 As shown, in the case where the water softening valve includes a valve housing 110, a main valve assembly 120 and an auxiliary valve assembly 130, the main valve assembly 120 cooperates with the auxiliary valve assembly 130 to realize the switching of multiple modes, which will be described below.

[0158] Regarding the water production mode:

[0159] Reference Figures 9 to 14 , Figures 16 to 18 As shown, it can be understood that in the water production mode, the main water production flow channel 126 of the main valve core 124 is connected, the main water production flow channel 126 connects the main cavity 111 and the raw water inlet 113, the auxiliary cavity 112 and the soft water inlet 119 are connected, and the raw water inlet 113, the main water production flow channel 126, the main cavity 111, the raw water outlet 118, the soft water inlet 119, the auxiliary cavity 112 and the soft water outlet 114 are connected. The main cavity 111 and the main valve assembly 120 are mainly used to send water to the softening device 190 in the water production mode, which helps to increase the flow of the soft water valve to the softening device 190, and then increases the flow of the soft water produced by the softening device 190, so as to facilitate the user to use the soft water.

[0160] In the water production mode, the main cavity 111 cooperates with the main valve assembly 120, so that the raw water inlet 113 is in communication with the main cavity 111, the auxiliary cavity 112 cooperates with the auxiliary valve assembly 130, so that the auxiliary cavity 112 is in communication with the soft water outlet 114, based on the communication of the raw water inlet 113, the main water production flow channel 126, the main cavity 111, the raw water outlet 118, the soft water inlet 119, the auxiliary cavity 112 and the soft water outlet 114, water flows along the path of the raw water inlet 113, the main water production flow channel 126, the main cavity 111, the raw water outlet 118, the soft water inlet 119, the auxiliary cavity 112 and the soft water outlet 114, so as to realize water supply to the softening device 190 through the main valve assembly 120 and the main cavity 111, and the soft water obtained after being softened by the softening device 190 can be discharged to the auxiliary cavity 112 through the soft water inlet 119, and the soft water in the auxiliary cavity 112 is discharged through the soft water outlet 114, in this process, the auxiliary cavity 112 and the auxiliary valve assembly 130 are used to communicate the soft water inlet 119 and the auxiliary cavity 112, so that the soft water can be discharged from the soft water inlet 119 to the auxiliary cavity 112, and the soft water is discharged from the auxiliary cavity 112 to the soft water outlet 114, so as to facilitate the user to take water.

[0161] Wherein, the main driving part 125 is used for driving the main valve core 124 to move, so as to switch the main valve core 124 to communicate with the main water production flow channel 126. It can be understood that: the main water production flow channel 126 can be communicated in some modes and disconnected in some modes.

[0162] Wherein, referring to Figure 9 It is shown that the main valve core 124 includes a main static valve piece 122 and a main dynamic valve piece 121, the main dynamic valve piece 121 is connected to the main driving part 125, the main static valve piece 122 is fixed with the valve shell 110, the main static valve piece 122 is configured with a main valve water inlet hole 1221, the main dynamic valve piece 121 is configured with a main valve water inlet 1211, the main valve water inlet hole 1221 is in communication with the raw water inlet 113, the main valve water inlet 1211 is in communication with the main cavity 111, and the main valve water inlet hole 1221 and the main valve water inlet 1211 are in communication to form the main water production flow channel 126. The main driving part 125 drives the main dynamic valve piece 121 to adjust the position relative to the main static valve piece 122, so as to realize the on-off adjustment of the main cavity 111 and the raw water inlet 113, which is simple in structure and convenient to adjust.

[0163] It can be understood that in the water production mode, the main drive part 125 drives the main valve piece 121 to move, so that the main valve water inlet 1211 and the main valve water hole 1221 are correspondingly communicated, that is, the main water production flow channel 126 formed by the main valve water inlet 1211 and the main valve water hole 1221 is communicated, and the water at the raw water inlet 113 can flow to the main cavity 111 through the main water production flow channel 126. In the partial non-water production mode, the main drive part 125 drives the main valve piece 121 to move, so that the main valve water inlet 1211 and the main valve water hole 1221 are not correspondingly communicated, that is, the main valve water inlet 1211 and the main valve water hole 1221 are disconnected, the main water production flow channel 126 is disconnected, the raw water inlet 113 cannot be communicated with the main cavity 111, and the water at the raw water inlet 113 cannot flow to the main cavity 111.

[0164] It can be understood that when the water softener switches from other modes to the water production mode, the main drive part 125 drives the main valve piece 121 to rotate to the first main valve position, at which time the main valve water inlet 1211 and the main valve water hole 1221 are communicated to form the main water production flow channel 126, so that the raw water inlet 113 can be communicated with the main cavity 111 through the main water production flow channel 126, and water can be injected into the resin tank through the main water production flow channel 126.

[0165] When the main drive part 125 is used to drive the main valve piece 121 to rotate, the main valve piece 121 can be rotated to communicate or disconnect the main valve water inlet 1211 and the main valve water hole 1221. The main valve water hole 1221 can be a fan-shaped hole, and the main valve water inlet 1211 can be formed through the fan-shaped gap of the main valve piece 121 to ensure the flow area of the raw water.

[0166] The above describes the main valve assembly 120, the main cavity 111 and the valve shell 110 in the water production mode.

[0167] The water production mode is the main function mode of the water softener, and other function modes (water injection mode, salt suction mode, cleaning mode) of the water softener 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.

[0168] Next, the auxiliary valve assembly 130, the auxiliary cavity 112 and the valve shell 110 in the water production mode are described.

[0169] In the water production mode, the secondary water production flow passage 136 of the secondary valve core 134 is communicated, the secondary water production flow passage 136 communicates the soft water inlet 119 and the secondary cavity 112, so that the raw water inlet 113, the main water production flow passage 126, the main cavity 111, the raw water outlet 118, the soft water inlet 119, the secondary water production flow passage 136, the secondary cavity 112 and the soft water outlet 114 are communicated. It can be understood that in the water production mode, the secondary valve core 134 is driven by the secondary driving part 135, so that the secondary valve core 134 communicates the soft water inlet 119 and the secondary cavity 112. Specifically, in the water production mode, the secondary water production flow passage 136 of the secondary valve core 134 is communicated, the secondary water production flow passage 136 is mainly used to communicate the soft water inlet 119 and the secondary cavity 112, based on the state of the main valve assembly 120 in the water production mode, it is known that the raw water inlet 113, the main water production flow passage 126, the main cavity 111, the raw water outlet 118 and the soft water inlet 119 are communicated, that is, the raw water can be transported from the raw water outlet 118 to the softening device 190, and after the softening device 190 converts the raw water into soft water, the soft water is transported from the soft water inlet 119 to the valve housing 110. At this time, the soft water inlet 119 is communicated through the secondary water production flow passage 136 and the secondary cavity 112, so that the soft water inlet 119, the secondary water production flow passage 136, the secondary cavity 112 and the soft water outlet 114 are communicated, and the soft water at the soft water inlet 119 can flow along the path of the secondary water production flow passage 136, the secondary cavity 112 and the soft water outlet 114, so that the user can obtain soft water at the soft water outlet 114, realizing the water production function of the soft water valve.

[0170] It can be understood that the secondary driving part 135 drives the secondary valve core 134 to move, so that the secondary valve core 134 is in the first secondary valve position, at this time the secondary valve core 134 can communicate the secondary cavity 112 and the soft water inlet 119, so that the water at the soft water inlet 119 can flow into the secondary cavity 112.

[0171] It can be understood that when the secondary valve core 134 is in the first secondary valve position, the secondary water production flow passage 136 of the secondary valve core 134 is communicated, and the soft water inlet 119 is communicated through the secondary water production flow passage 136 and the secondary cavity 112.

[0172] Among them, the secondary valve core 134 includes a secondary static valve piece 132 and a secondary dynamic valve piece 131, the secondary dynamic valve piece 131 is connected to the secondary driving part 135, the secondary static valve piece 132 is fixed with the valve housing 110, the secondary static valve piece 132 is configured with a softening connection hole 1322, the secondary dynamic valve piece 131 is configured with a secondary valve water inlet 1314, the softening connection hole 1322 is communicated with the soft water inlet 119, the secondary valve water inlet 1314 is communicated with the secondary cavity 112, and the softening connection hole 1322 and the secondary valve water inlet 1314 are communicated to form the secondary water production flow passage 136.

[0173] It can be understood that, in the water production mode, the secondary drive part 135 drives the secondary movable valve plate 131 to rotate, so that the relative position between the secondary movable valve plate 131 and the secondary static valve plate 132 changes, the secondary water inlet 1314 and the softening connection hole 1322 are communicated to form a secondary water production flow channel 136, at this time the soft water inlet 119 can be communicated with the secondary cavity 112 through the secondary water production flow channel 136, so that the water at the soft water inlet 119 can flow into the secondary cavity 112. In the partial non-water production mode, for example, the salt suction mode, the secondary drive part 135 drives the secondary movable valve plate 131 to rotate relative to the secondary static valve plate 132, so that the secondary water inlet 1314 and the softening connection hole 1322 are no longer communicated, that is, the secondary water production flow channel 136 at this time is disconnected, and the soft water inlet 119 cannot be communicated with the secondary cavity 112 through the secondary water production flow channel 136, so as to realize the operation of other modes of the soft water valve.

[0174] It can be understood that, in the water production mode, the secondary drive part 135 drives the secondary movable valve plate 131 to move to the first secondary valve position, so that the secondary movable valve plate 131 and the secondary static valve plate 132 can form a communicated secondary water production flow channel 136, and the soft water inlet 119 and the secondary cavity 112 can be communicated through the secondary water production flow channel 136.

[0175] In some cases, the secondary cavity 112 and the soft water inlet 119 can be always communicated, without the need for regulation by the secondary valve core 134 (not shown in the figure), which can simplify the structure of the secondary valve core 134. Regarding the water injection mode:

[0176] Reference Figures 9 to 14 、 Figures 19 to 21 and Figures 36 to 39 It can be understood that the valve housing 110 is provided with a salt tank connection port 1110 for connecting the salt tank 200, and in the water injection mode, the water injection flow channel 137 of the secondary valve core 134 communicates the soft water inlet 119 with the salt tank connection port 1110, so that the soft water inlet 119, the water injection flow channel 137 and the salt tank connection port 1110 are communicated. By adjusting the state of the secondary valve assembly 130, the softening device 190 is communicated with the salt tank 200, and the softened soft water of the softening device 190 is delivered into 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.

[0177] Specifically, in the water injection mode, the secondary drive part 135 drives the secondary valve core 134 to rotate to the second secondary valve position, the water injection flow channel 137 of the secondary valve core 134 communicates the salt suction water injection hole 1324 with the salt tank connection port 1110, and the salt suction water injection hole 1324 can be communicated with the soft water inlet 119 or the secondary cavity 112. The water at the salt suction water injection hole 1324 can be directly or indirectly delivered to the salt tank connection port 1110, and then delivered from the salt tank connection port 1110 into the salt tank 200, to realize the water injection operation of the salt tank 200.

[0178] It should be noted that the way water flows from the soft water inlet 119 to the salt tank connection port 1110: when the state of the main cavity 111 and the main valve assembly 120 can be the same as the water making mode, raw water can flow along the path of the raw water inlet 113, the main water making flow channel 126, the main cavity 111, the raw water outlet 118 and the soft water inlet 119, so that the raw water is transported to the soft water outlet 114 after being converted into soft water by the softening device 190, and the soft water is transported from the soft water outlet 114 to the salt tank connection port 1110, realizing the operation of injecting soft water into the salt tank 200.

[0179] The way water flows from the auxiliary cavity 112 to the salt tank connection port 1110: when the flow channel of the main valve assembly 120 is switched so that the raw water inlet 113 and the auxiliary cavity 112 are communicated, that is, at this time the water at the raw water inlet 113 can be directly transported into the auxiliary cavity 112, and the auxiliary cavity 112 and the salt tank connection port 1110 can be communicated by the auxiliary valve core 134, realizing the operation of injecting raw water into the salt tank 200.

[0180] It should be noted that the water at the soft water inlet 119 can directly flow to the water injection flow channel 137, that is, the soft water inlet 119 is directly communicated with the water injection flow channel 137; the water at the soft water inlet 119 can also flow to the water injection flow channel 137 after passing through the auxiliary cavity 112, that is, the soft water inlet 119, the auxiliary cavity 112 and the water injection flow channel 137 are communicated.

[0181] That is, the soft water inlet 119 is communicated with the water injection flow channel 137 through the auxiliary cavity 112, realizing the communication of the soft water inlet 119, the auxiliary cavity 112 and the water injection flow channel 137, so that the water at the soft water inlet 119 can flow to the water injection flow channel 137 after passing through the auxiliary cavity 112, and the water at the soft water inlet 119 can also flow to the water injection flow channel 137 and the auxiliary cavity 112. That is, it can be ensured that water will flow into the auxiliary cavity 112 in the water injection mode, and the water in the auxiliary cavity 112 can flow out of the soft water outlet 114, ensuring that the user still has water available in the water injection mode, and at this time the water flowing into the auxiliary cavity 112 is soft water treated by the softening device 190, that is, the user still has soft water available in the water injection mode.

[0182] It can be understood that in the water injection mode, the way the raw water inlet 113 sends water to the softening device 190 can be the same as the above-mentioned water making mode, that is, the raw water inlet 113 and the raw water outlet 118 can be communicated by the main cavity 111 and the main valve assembly 120, so that the raw water flows along the path of the raw water inlet 113, the main water making flow channel 126, the main cavity 111 and the raw water outlet 118 into the softening device 190, which helps to simplify the structure of the main cavity 111 and the main valve assembly 120.

[0183] With the main valve core 124 equipped with a main water control channel 126, the main water control channel 126 connects the main chamber 111 with the raw water inlet 113. For details, please refer to the above description of the water control mode. Figure 20 As shown, details will not be repeated here. It can be understood that the difference between the water injection mode and the water production mode lies in the different states of the secondary valve assembly 130. When the soft water valve switches between the water injection mode and the water production mode, the main valve core 124 is in the first main valve position. By switching the position of the secondary valve core 134, the two modes can be switched. In the water production mode, the position of the secondary valve core 134 can be understood as the first secondary valve position; in the water injection mode, the position of the secondary valve core 134 can be understood as the second secondary valve position. The secondary drive unit 135 drives the secondary valve core 134 to rotate, causing it to switch between the first and second secondary valve positions. That is, the secondary drive unit 135 drives the secondary valve core 134 to rotate until the water injection channel 137 is connected or disconnected, and the secondary water production channel 136 is also connected or disconnected accordingly. The secondary valve assembly 130 has a simple structure and is easy to operate.

[0184] The auxiliary valve core 134 includes an auxiliary stationary valve plate 132 and an auxiliary moving valve plate 131. The auxiliary moving valve plate 131 is connected to the auxiliary drive unit 135, and the auxiliary stationary valve plate 132 is fixed to the valve housing 110. The auxiliary stationary valve plate 132 has a softening connection hole 1322 and a brine suction and water injection hole 1324. The softening connection hole 1322 communicates with the soft water inlet 119, and the brine suction and water injection hole 1324 communicates with the brine tank connection port 1110. The softening connection hole 1322 and the brine suction and water injection hole 1324 communicate to form a water injection channel 137. The auxiliary stationary valve plate 132 and the auxiliary moving valve plate 131 cooperate to connect the softening device 190 and the brine tank 200, so as to smoothly send the soft water in the softening device 190 into the brine tank 200. The structure is simple.

[0185] Specifically, in the water injection mode, the auxiliary drive unit 135 drives the auxiliary valve plate 131 to rotate to the second auxiliary valve position, causing a relative positional change between the auxiliary valve plate 131 and the auxiliary stationary valve plate 132. This connects the softening connection hole 1322 and the brine injection hole 1324, forming a water injection channel 137. The soft water inlet 119 connects to the brine tank connection port 1110 through the water injection channel 137, allowing water at the soft water inlet 119 to be transported to the brine tank connection port 1110 via the water injection channel 137. In some non-water injection modes, the auxiliary drive unit 135 drives the auxiliary valve plate 131 to rotate, causing the brine injection hole 1324 and the softening connection hole 1322 to become disconnected. This prevents the soft water inlet 119 from connecting to the brine tank connection port 1110 via the water injection channel 137, thus preventing water at the soft water inlet 119 from flowing to the brine tank connection port 1110. This allows the soft water valve to operate in different modes.

[0186] The auxiliary valve core 134 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 135, and the auxiliary static valve plate 132 is fixed to the valve housing 110. The auxiliary static valve plate 132 is configured with a softened connection hole 1322 and a salt suction and water injection hole 1324. The softened connection hole 1322 is communicated with the softened water inlet 119, and the salt suction and water injection hole 1324 is communicated with the auxiliary cavity 112 and the salt tank connecting port 1110. The auxiliary dynamic valve plate 131 is configured with an auxiliary valve water inlet 1314, which is communicated with the auxiliary cavity 112. The softened connection hole 1322 and the salt suction and water injection hole 1324 are communicated through the auxiliary valve water inlet 1314 to form a water injection flow channel 137.

[0187] It can be understood that, by driving the auxiliary dynamic valve plate 131 to rotate through the auxiliary driving part 135, the softened connection hole 1322 and the salt suction and water injection hole 1324 can be communicated through the auxiliary valve water inlet 1314 to form the water injection flow channel 137. At this time, the water injection flow channel 137 can not only communicate the softened water inlet 119 and the salt tank connecting port 1110, but also communicate the softened water inlet 119 and the auxiliary cavity 112, so that the softened water at the softened water inlet 119 can flow to the salt tank connecting port 1110 or flow to the softened water outlet 114 after passing through the auxiliary cavity 112.

[0188] When the water softener valve includes a jet device 160, the jet device 160 is used to communicate the salt suction and water injection hole 1324 and the salt tank connecting port 1110, that is, the jet device 160 is used to communicate the water injection flow channel 137 and the salt tank connecting port 1110. By switching the state of the auxiliary valve core 134, the water softener valve can also use the jet device 160 to suck the salt solution from the salt tank 200 and send it into the softening device 190. That is, in the water injection mode and the salt suction mode, the flow paths of water between the softening device 190, the jet device 160 and the salt tank 200 are different. In the water injection mode, water flows from the softening device 190 to the jet device 160 through the auxiliary valve assembly 130, or flows from the auxiliary cavity 112 to the jet device 160, and then flows into the salt tank connecting port 1110 through the jet device 160. In the salt suction mode, the raw water in the auxiliary cavity 112 drives the salt solution in the salt tank 200 into the jet device 160, and then sends the mixed solution in the jet device 160 into the softening device 190 through the auxiliary valve assembly 130. It should be noted that in the water injection mode and the salt suction mode, the flow channels communicated in the auxiliary valve assembly 130 are different. Of course, in the water injection mode, the water flowing through the water injection flow channel 137 of the auxiliary valve assembly 130 to the salt tank connecting port 1110 can also not pass through the jet device 160 but directly flow into the salt tank connecting port 1110. At this time, the salt suction and water injection hole 1324 can be directly communicated with the salt tank connecting port 1110.

[0189] In the above embodiments, in the water injection mode, the path of the raw water inlet 113 to the secondary valve assembly 130 is the same as that in the water production mode, that is, the softened water is delivered from the softening device 190 to the salt tank connection port 1110 through the soft water valve control, but the water injection mode can also introduce raw water into the salt tank connection port 1110 in other ways. In some cases, in the water injection mode, the main cavity 111 can not be involved in the work, by adjusting the state of the secondary valve assembly 130, in the case of the raw water inlet 113 communicating with the secondary cavity 112, the secondary valve assembly 130 is adjusted to make the secondary cavity 112 communicate with the salt tank connection port 1110, or in other ways to make the soft water outlet 114 communicate with the salt tank connection port 1110, the raw water is introduced into the salt tank 200 through the salt tank connection 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 secondary cavity 112 of the valve housing 110 communicates with the raw water inlet 113, the water injection channel 137 communicates the secondary cavity 112 with the salt tank connection port 1110, and the raw water in the secondary 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 secondary valve inlet 1314 of the secondary valve piece 131 communicates with the salt suction injection hole 1324, and the raw water in the secondary cavity 112 flows along the secondary valve inlet 1314, the salt suction injection hole 1324 and the salt tank connection port 1110. At this time, the main valve assembly 120 can disconnect or communicate the main cavity 111 with the raw water inlet 113.

[0190] 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 predetermined time, which can be 1 hour, 2 hours, etc. This process can be understood as the salt tank 200 entering the salt melting state, and during the salt melting state, the water production mode can be executed, so that the user can take the softened 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 suction mode is executed, which will be described below.

[0191] Salt suction mode:

[0192] Referring to Figures 9 to 14 , Figures 22 to 34 and Figures 36 to 39 , it can be understood that the valve housing 110 is connected with the jet device 160, the valve housing 110 is provided with the salt tank connection port 1110, the salt solution in the salt tank connection port 1110 is sucked into the salt tank connection port 1110 through the jet device 160, and the salt solution is sent into the softening device 190 through the cooperation of the jet device 160 and the secondary valve assembly 130, and the waste water after the regeneration of the softening material in the softening device 190 is discharged.

[0193] In the salt suction mode, combined with Figures 22 to 24 and Figures 36 to 39As shown, the valve housing 110 is connected with a fluidic device 160, the fluidic device 160 is provided with a fluidic flow channel, the valve housing 110 is provided with a salt tank connecting port 1110, in the salt suction mode, the fluidic inlet 161 of the fluidic flow channel is communicated with the raw water inlet 113 through the secondary valve core 134, the suction inlet 163 of the fluidic flow channel is communicated with the salt tank connecting port 1110, the fluidic outlet 162 of the fluidic flow channel is communicated with the soft water inlet 119 through the secondary valve core 134. The soft water inlet 119 is communicated with the softening device 190, and the raw water inlet 113, the fluidic inlet 161, the fluidic outlet 162 and the soft water inlet 119 are communicated, so that the raw water in the raw water inlet 113 can flow into the fluidic flow channel, the raw water and the salt water in the salt tank connecting port 1110 are mixed in the fluidic flow channel to obtain a mixed liquid, and the mixed liquid is introduced into the softening device 190 along the fluidic outlet 162 and the soft water inlet 119. Among them, the suction inlet 163 is located on the flow path between the fluidic inlet 161 and the fluidic outlet 162, the raw water flows from the fluidic inlet 161 to the fluidic outlet 162, the raw water flows in the fluidic flow 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 fluidic inlet 161 and the fluidic flow channel along the salt tank connecting port 1110 and the suction inlet 163, so that the salt solution and the raw water are mixed in the fluidic flow channel to obtain a mixed solution, and the mixed solution flows to the softening device 190 along the fluidic outlet 162, completing the process of sending the mixed solution into the softening device 190.

[0194] It can be understood that in the salt suction mode, the secondary valve core 134 is located at the third secondary valve position under the drive of the secondary drive part 135, so that the fluidic inlet 161 of the fluidic flow channel is communicated with the raw water inlet 113, and the fluidic outlet 162 of the fluidic flow channel is communicated with the soft water inlet 119. The raw water can flow along the path of the raw water inlet 113, the fluidic inlet 161, the fluidic outlet 162 and the soft water inlet 119.

[0195] In some cases, the fluidic inlet 161 is communicated with the secondary cavity 112 through the secondary valve core 134, and the secondary cavity 112 is communicated with the raw water inlet 113, so that the fluidic inlet 161 is communicated with the raw water inlet 113. The raw water flows from the raw water inlet 113 to the secondary cavity 112, and then flows from the secondary cavity 112 to the fluidic flow channel through the fluidic inlet 161, realizing the communication between the fluidic inlet 161 and the raw water inlet 113. Of course, the fluidic inlet 161 can also be communicated with the raw water inlet 113 in other ways, for example, the fluidic inlet 161 is directly communicated with the raw water inlet 113, or is communicated with the raw water inlet 113 through other valve assemblies, without the need to pass through the secondary valve assembly 130.

[0196] It can be understood that when the jet flow inlet 161 is communicated with the raw water inlet 113 through the auxiliary cavity 112, the raw water will first flow into the auxiliary cavity 112, part of the raw water in the auxiliary cavity 112 will flow into the jet flow channel, and another part of the raw water in the auxiliary cavity 112 will be discharged from the soft water outlet 114, so that the user still has water available when the soft water valve is in the salt suction mode. And the mixed solution obtained after the salt solution and the raw water are mixed in the jet flow channel flows to the soft water inlet 119 through the jet flow outlet 162, and the soft water inlet 119 is disconnected from the auxiliary cavity 112 through the auxiliary valve assembly 130, that is, the soft water inlet 119 and the auxiliary cavity 112 are not communicated, and the salt water at the soft water inlet 119 will not flow into the auxiliary cavity 112, ensuring that the water in the auxiliary cavity 112 is raw water rather than salt water, and ensuring that the user has raw water available when the soft water valve is in the salt suction mode.

[0197] In some cases, the auxiliary driving part 135 drives the auxiliary valve 131 to rotate, so that the auxiliary valve water inlet 1314 is misaligned with the softening connection hole 1322, and the auxiliary valve 131 blocks the softening connection hole 1322 and the auxiliary cavity 112. When in the salt suction mode, the auxiliary valve water inlet 1314 is misaligned with the softening connection hole 1322, that is, the soft water inlet 119 is separated from the auxiliary valve water inlet 1314, so that the soft water inlet 119 is separated from the auxiliary cavity 112, and the soft water inlet 119 and the auxiliary cavity 112 are blocked, which can avoid the salt water at the soft water inlet 119 polluting the water at the auxiliary cavity 112.

[0198] Wherein, the first blowdown flow channel 127 of the main valve core 124 communicates the raw water outlet 118 with the blowdown port 115 of the valve shell 110, so that the raw water of the raw water inlet 113 and the salt water of the salt tank connection port 1110 are mixed in the jet flow channel to obtain a mixed liquid, and the mixed liquid flows along the jet flow channel, the soft water inlet 119, the raw water outlet 118, the first blowdown flow channel 127 and the blowdown port 115. The mixed liquid obtained by mixing the raw water and the salt water flows along the jet flow outlet 162 and the soft water inlet 119 into the softening device 190, and the mixed liquid is regenerated after the softening device 190 and is discharged from the raw water outlet 118. Since the raw water outlet 118 is communicated with the blowdown port 115 of the valve shell 110 through the first blowdown flow channel 127, the mixed liquid will flow along the raw water outlet 118, the first blowdown flow channel 127 and the blowdown port 115 and be discharged from the valve shell 110.

[0199] In some cases, the raw water outlet 118 is communicated with the first blowdown flow channel 127, for example, through the main cavity 111, that is, the mixed liquid will flow along the raw water outlet 118, the main cavity 111 and the first blowdown flow channel 127. Of course, the raw water outlet 118 can also be directly communicated with the first blowdown flow channel 127, so that the structure of the soft water valve is simpler.

[0200] In some cases, 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, and the mixed solution cleans 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, which can be selected as needed.

[0201] In the case where the raw water in the auxiliary chamber 112 is drained to the jet flow inlet 161 through the auxiliary valve assembly 130, the mixed solution of the jet flow outlet 162 is drained to the soft water inlet 119 through the auxiliary valve assembly 130, and the sewage of the raw water outlet 118 is drained to the sewage outlet 115 through the main valve assembly 120, the first salt suction channel 1341 of the auxiliary valve core 134 and the second salt suction channel 1342 are communicated, the first salt suction channel 1341 communicates the auxiliary chamber 112 and the jet flow inlet 161, the second salt suction channel 1342 communicates the jet flow outlet 162 and the soft water inlet 119, the first sewage discharge channel 127 of the main valve core 124 communicates the raw water outlet 118 and the sewage passage 1114 of the valve shell 110 (the end of the sewage passage 1114 forms the sewage outlet 115), the raw water in the auxiliary chamber 112 enters the jet flow inlet 161 along the first salt suction channel 1341, the raw water and the salt solution are mixed in the jet flow channel to obtain a mixed solution, and the mixed solution flows out along the jet flow outlet 162, the soft water inlet 119, the raw water outlet 118, the first sewage discharge channel 127 and the sewage outlet 115, thereby achieving slow washing of the softening device 190.

[0202] It should be noted that when the first salt suction channel 1341 communicates the auxiliary chamber 112 and the jet flow inlet 161, the auxiliary chamber 112 and the raw water inlet 113 are communicated, so that the raw water at the raw water inlet 113 can flow to the jet flow channel along the auxiliary chamber 112 and the jet flow inlet 161. Of course, the first salt suction channel 1341 can also directly communicate the jet flow inlet 161 and the raw water inlet 113, so that the raw water at the raw water inlet 113 can be transported to the jet flow channel through the jet flow inlet 161.

[0203] In some cases, the valve shell 110 is provided with a filter passage 1115, and a filter is arranged in the filter passage 1115. The filter passage 1115 communicates the jet flow inlet 161 and the first salt suction channel 1341, so that the raw water flowing out of the first salt suction channel 1341 is filtered through the filter passage 1115 before being sent to the softening device 190 along the jet flow channel and the second salt suction channel 1342. The filtered raw water is used for regeneration of the softening material.

[0204] The filter element can be a filter screen, filter core, filter membrane, etc., and the structure of the filter element is various. The filter element can be fixed in the filter channel 1115, and the filter element can be fixed by clamping, fastener connection, threaded connection, etc., and the fixing mode of the filter element is various and can be selected as required. The filter element can be detachably connected to the filter channel 1115, which is convenient for replacement.

[0205] The valve shell 110 is provided with a mounting channel, and the fluidic device 160 is detachably mounted in the mounting channel, which is convenient for dismounting the fluidic device 160. In some cases, as shown in Figure 35 and Figure 40 The valve shell 110 is integrally formed with the mounting channel, which is convenient for machining the valve shell 110 and can also simplify the structure of the water softener. Alternatively, the valve shell 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 shell 110 is provided with a filter channel 1115, the filter channel 1115 can also be formed by a structure member independent of the valve shell 110, such as a pipe member detachably connected to the valve shell 110. The pipe member can be connected with the independent fluidic device 160 to form an integral whole, thereby reducing the number of parts. Based on the foregoing, the mounting modes of the fluidic device 160 and the filter element in the valve shell 110 are various and can be selected as required, which will not be listed one by one here.

[0206] It should be noted that, as shown in Figures 36 to 39 The fluidic device 160 can be a Venturi structure, the left side of the valve shell 110 is provided with the fluidic device 160, two channels are opened on the left side of the valve shell 110, the lowermost channel is provided with the filter channel 1115 for mounting the filter element, which is used for filtering impurities and preventing the fluidic device 160 from being blocked, and the upper channel is provided with a mounting channel for mounting the fluidic device 160, and 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 is sucked during regeneration.

[0207] As shown in Figures 36 to 39 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, 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 inserted with a jet flow limiting member 166 to adjust the flow of the fluidic device 160.

[0208] Next, the structure of the sub-valve core 134 forming the first salt suction flow channel 1341 and the second salt suction flow channel 1342 will be described.

[0209] As shown in Figure 24As shown, the sub-valve core 134 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 135, the sub-static valve piece 132 is fixed with the valve housing 110, the sub-static valve piece 132 is configured with a salt suction water hole 1324, a brine hole 1323 and a softened water connection hole 1322, the sub-moving valve piece 131 is configured with a sub-valve water inlet 1314 and a sub-valve first groove 1311, the sub-valve water inlet 1314 is communicated with the sub-cavity 112, the salt suction water hole 1324 is communicated with the jet flow inlet 161, the sub-valve water inlet 1314 and the salt suction water hole 1324 are communicated to form a first salt suction flow channel 1341, the brine hole 1323 is communicated with the jet flow outlet 162, the softened water connection hole 1322 is communicated with the softened water inlet 119, the brine hole 1323 is communicated through the sub-valve first groove 1311 and the softened water connection hole 1322 to form a second salt suction flow channel 1342.

[0210] It can be understood that the sub-valve water inlet 1314 and the salt suction water hole 1324 are communicated to form the first salt suction flow channel 1341, so that the first salt suction flow channel 1341 can be communicated with the sub-cavity 112 and the jet flow inlet 161, and the water in the sub-cavity 112 can flow into the jet flow channel through the first salt suction flow channel 1341. The brine hole 1323 and the softened water connection hole 1322 are communicated through the sub-valve first groove 1311 to obtain the second salt suction flow channel 1342, so that the second salt suction flow channel 1342 can be communicated with the jet flow outlet 162 and the softened water inlet 119, and the mixed liquid after the raw water and the brine mixed in the jet flow channel can flow to the softened water inlet 119 through the second salt suction flow channel 1342, and then the mixed liquid enters the softening device 190 from the softened water inlet 119, so as to realize the conveying of the brine to the softening device 190. That is, in the salt suction mode, the raw water flows along the path of the sub-cavity 112, the sub-valve water inlet 1314, the salt suction water hole 1324, the jet flow inlet 161, the jet flow outlet 162 and the softened water inlet 119, and 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 connection port 1110, so that the salt solution and the raw water are mixed in the jet flow channel to obtain a mixed solution, and the mixed solution flows along the path of the jet flow outlet 162, the brine hole 1323, the sub-valve first groove 1311 and the softened water connection hole 1322, and the mixed solution enters the softening device 190 through the softened water connection hole 1322, and according to the above-mentioned path, the salt solution is conveyed.

[0211] 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.

[0212] In some cases, reference is made to Figure 41 and Figure 42As shown, the valve housing 110 comprises a communication passage 1113, which communicates the sub-cavity 112 and the raw water inlet 113, so that the raw water can be delivered to the sub-cavity 112 along the raw water inlet 113 and the communication passage 1113, which can simplify the flow path of the raw water delivery and the structure of the water softener valve.

[0213] It can be understood that the outlet of the communication passage 1113 communicates with the sub-cavity 112, and the inlet of the communication passage 1113 is adjustable by the raw water inlet 113 through the main valve core 124. By driving the main valve core 124 through the main driving part 125, the main valve core 124 can be switched between the third main valve position of communicating the communication passage 1113 and the raw water inlet 113 and the first main valve position of communicating the main cavity 111 and the raw water inlet 113. When the main valve core 124 is at the first main valve position, the raw water inlet 113 is disconnected from the inlet of the communication passage 1113, which realizes the adjustable connection between the communication passage 1113 and the raw water inlet 113, and realizes the adjustable connection between the sub-cavity 112 and the raw water inlet 113.

[0214] In the salt suction mode, the communication passage 1113 communicates with the raw water inlet 113 through the main valve core 124, and the raw water flows into the sub-cavity 112 through the raw water inlet 113, the main valve core 124 and the communication passage 1113. Then part of the water in the sub-cavity 112 flows to the soft water inlet 119 through the sub-valve core 134, and in the process of flowing to the soft water inlet 119, the raw water and the brine in the salt tank 200 are mixed, and the mixed solution after the raw water and the brine are mixed flows to the soft water inlet 119 and enters the softening device 190 from the soft water inlet 119. Another part of the water in the sub-cavity 112 can flow to the soft water outlet 114, so that the user can still have water available in the salt suction mode, at which time the raw water is taken from the soft water outlet 114.

[0215] 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. The following describes the flow path of the sewage generated after the mixed solution regenerates the softening material in the softening device 190.

[0216] Reference Figure 23 As shown, in the salt suction mode, the first sewage flow channel 127 of the main valve core 124 is communicated, and the first sewage flow channel 127 communicates the raw water outlet 118 and the sewage passage 1114 of the valve housing 110, so that the raw water outlet 118, the first sewage flow channel 127 and the sewage passage 1114 are communicated.

[0217] It can be understood that after the mixed liquid of raw water and brine enters the softening device 190, the sewage flows along the path of the raw water outlet 118, the first sewage flow channel 127 and the sewage passage 1114, so that the sewage can be discharged from the valve housing 110.

[0218] It should be noted that the raw water outlet 118 can be directly communicated with the first blow-off flow channel 127, or communicated with the first blow-off flow channel 127 through the main cavity 111. When the raw water outlet 118 is communicated with the first blow-off flow channel 127 through the main cavity 111, the sewage flows out of the valve housing 110 along the raw water outlet 118, the main cavity 111, the first blow-off flow channel 127 and the blow-off passage 1114, at this time, the main water flow channel 126 is disconnected, the main cavity 111 is disconnected with the raw water inlet 113, so that the sewage in the main cavity 111 will not mix with the raw water, which can avoid the raw water at the raw water inlet 113 being polluted, and ensure that the raw water flowing into the auxiliary cavity 112 from the raw water inlet 113 is raw water rather than sewage, and the auxiliary cavity 112 is communicated with the soft water outlet 114, that is, the water used by the user is the water in the auxiliary cavity 112, so that it is ensured that the user uses the raw water rather than the sewage when the soft water valve is in the salt suction mode.

[0219] It should be noted that the flow path of the main valve core 124 is the same in the backwashing mode and the salt suction mode, so that the soft water valve can discharge the sewage out of the valve housing 110 in the salt suction mode and the backwashing mode, and the two modes share one blow-off flow path, which can simplify the structure of the main valve core 124.

[0220] The main valve core 124 includes the main static valve plate 122 and the main dynamic valve plate 121, the main dynamic valve plate 121 is connected to the main driving part 125, the main static valve plate 122 is fixed to the valve housing 110, the main static valve plate 122 is provided with a main valve blow-off hole 1222, the main dynamic valve plate 121 is provided with a main valve water inlet 1211, the main valve blow-off hole 1222 is communicated with the blow-off passage 1114, the main valve water inlet 1211 is communicated with the raw water outlet 118, and the main valve water inlet 1211 and the main valve blow-off hole 1222 are communicated to form the first blow-off flow channel 127. The main driving part 125 drives the main valve core 124 to be in the third main valve position, so that the main valve core 124 forms the first blow-off flow channel 127, and the raw water outlet 118 and the blow-off passage 1114 are communicated through the first blow-off flow channel 127, so that the sewage in the valve housing 110 can be discharged.

[0221] It can be understood that the first blow-off flow channel 127 formed by the communication of the main valve water inlet 1211 and the main valve blow-off hole 1222 can communicate the raw water outlet 118 and the blow-off passage 1114, so that the sewage can flow along the raw water outlet 118, the main valve water inlet 1211, the main valve blow-off hole 1222 and the blow-off passage 1114 and be discharged out of the valve housing 110, thereby realizing the discharge of the sewage.

[0222] Of course, the main static valve plate 122 can also be provided with two main valve blow-off holes 1222 (not shown in the figure), one main valve blow-off hole 1222 is communicated with the raw water outlet 118, and the other main valve blow-off hole 1222 is communicated with the blow-off port 115 of the valve housing 110, and the two blow-off holes are communicated through the groove of the main dynamic valve plate 121, which can also discharge the sewage in the softening device 190.

[0223] The following describes the water injection mode performed by the auxiliary valve core 134, assuming that the valve housing 110 has a jet flow channel and other related structures.

[0224] In water injection mode, refer to Figure 21 As shown, the water injection channel 137 of the auxiliary valve core 134 is connected, the water injection channel 137 is connected to the jet inlet 161 and the soft water inlet 119, and the main chamber 111 is connected to the raw water inlet 113, so that the raw water inlet 113, the main chamber 111, the raw water outlet 118, the soft water inlet 119, the water injection channel 137, the jet channel and the brine tank connection port 1110 are connected. That is, water flows along the path of the raw water inlet 113, the main chamber 111, the raw water outlet 118, the soft water inlet 119, the water injection channel 137, the jet channel and the brine tank connection port 1110, and then enters the brine tank 200 through the brine tank connection port 1110.

[0225] It should be noted that the path for sending soft water into the brine tank 200 and the flow path of soft water after it flows out of the softening device 190 are provided here. The path for raw water to flow into the softening device 190 is not described. The path for raw water to flow into the softening device 190 can be referred to the water production mode described above, that is, the main water production channel 126 is connected to send the raw water at the raw water inlet 113 to the raw water outlet 118. Of course, it can also be done through other paths.

[0226] Understandably, the jet inlet 161 is connected to the soft water inlet 119, allowing soft water to flow into the jet channel through the jet inlet 161. At this time, the jet outlet 162 is closed, and the suction inlet 163 is connected to the salt tank connection port 1110, allowing water to flow from the jet inlet 161 to the suction inlet 163, and then to the salt tank connection port 1110.

[0227] The auxiliary valve core 134 includes an auxiliary stationary valve plate 132 and an auxiliary moving valve plate 131. The auxiliary moving valve plate 131 is connected to the auxiliary drive unit 135. The auxiliary stationary valve plate 132 is fixed to the valve housing 110. The auxiliary stationary valve plate 132 is constructed with a softening connection hole 1322 and a brine suction water injection hole 1324. The auxiliary moving valve plate 131 is constructed with a auxiliary valve inlet 1314. The brine suction water injection hole 1324 is connected to the jet inlet 161. The softening connection hole 1322 is connected to the soft water inlet 119. The softening connection hole 1322, the auxiliary valve inlet 1314 and the brine suction water injection hole 1324 are connected to form a water injection channel 137. In the water injection mode, the jet outlet 162 is closed, so that water flows into the jet channel from the brine suction water injection hole 1324. The water in the jet channel flows to the brine tank connection port 1110 through the suction port 163. The softening connection hole 1322, the auxiliary valve inlet 1314, the brine injection hole 1324 and the jet inlet 161 are connected, so that the soft water at the soft water inlet 119 can flow into the jet channel through the jet inlet 161.

[0228] When the soft water is delivered into the jet flow channel, the jet outlet 162 is closed, the jet 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 soft water flows into the jet 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.

[0229] Based on the fact that the jet outlet 162 corresponds to the salt water hole 1323, the closing of the jet outlet 162 can be achieved by moving the secondary movable valve disc 131 to close the salt water hole 1323, so that the water in the jet flow channel enters the salt tank connecting port 1110 through the suction inlet 163.

[0230] In combination with the above 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 135 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 134 between the position where the water injection flow channel 137 is communicated and the position where the first salt suction flow channel 1341 and the second salt suction flow channel 1342 are communicated.

[0231] The secondary driving part 135 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 134 between the position where the water injection flow channel 137 is communicated and the position where the jet outlet 162 and the soft water inlet 119 are communicated.

[0232] It can be understood that the secondary movable valve disc 131 is driven to rotate by the secondary driving part 135, so as to switch the secondary valve core 134 between the second secondary valve position corresponding to the water injection mode and the third secondary valve position corresponding to the salt suction mode. When the soft water valve is in the water injection mode, i.e., the secondary valve core 134 is in the second secondary valve position, the water injection flow channel 137 of the secondary valve core 134 is communicated, so that the soft water inlet 119 can be communicated with the water injection flow channel 137 and the jet inlet 161, and the soft water at the soft water inlet 119 can flow into the jet flow channel through the water injection flow channel 137 and the jet inlet 161, and then flow to the salt tank connecting port 1110, thereby achieving the water injection operation on the salt tank 200. When the soft water valve is in the salt suction mode, i.e., the secondary valve core 134 is in the third secondary valve position, the secondary valve core 134 communicates the jet outlet 162 and the soft water inlet 119, so that the mixed solution after the raw water and the salt water in the jet flow channel are mixed can flow from the jet outlet 162 to the soft water inlet 119, and then flow into the softening device 190, thereby achieving the salt water injection operation on the softening device 190.

[0233] It is important to note that when the auxiliary valve core 134 is in the second auxiliary valve position, the main valve core 124 is in the first main valve position; and when the auxiliary valve core 134 is in the third auxiliary valve position, the main valve core 124 is in the third main valve position. In other words, when the soft water valve switches between water injection mode and brine suction mode, the main drive unit 125 drives the main valve core 124 to change between the first and third main valve positions to achieve the switching between water injection mode and brine suction mode.

[0234] After the water injection mode and the brine absorption mode, the softening material in the softening device 190 is regenerated. The softening device 190 also needs to be cleaned. The softening valve can control the execution of the cleaning mode, which includes at least one of the backwash mode and the forward wash mode. The goal is to ensure that the softening device 190 and the softening valve are cleaned.

[0235] The backwashing mode is explained below.

[0236] refer to Figures 9 to 14 as well as Figures 25 to 27 As shown, in the backwash mode, the backwash channel of the auxiliary valve core 134 is connected, and the backwash channel is connected to the soft water inlet 119 and the raw water inlet 113. The main drive unit 125 is used to drive the main valve core 124 to move to the first sewage discharge channel 127, which is connected to the raw water outlet 118 and the sewage outlet 115 of the valve body 110.

[0237] Understandably, the backwash channel connects the soft water inlet 119 and the raw water inlet 113, allowing raw water to flow along these two points. The raw water then flows into the softening device 190 from the soft water inlet 119 and exits from the raw water outlet 118, thus achieving backwashing of the softening device 190. Since the first sewage discharge channel 127 connects the raw water outlet 118 and the drain port 115 of the valve body 110, wastewater flowing from the raw water outlet 118 can be discharged from the valve body 110 along the first sewage discharge channel 127 and the drain port 115, thus achieving sewage discharge from the soft water valve.

[0238] The auxiliary valve core 134 includes an auxiliary stationary valve plate 132 and an auxiliary moving valve plate 131. The auxiliary moving valve plate 131 is connected to the auxiliary drive unit 135. The auxiliary stationary valve plate 132 is fixed to the valve housing 110. The auxiliary stationary valve plate 132 is configured with a softening connection hole 1322. The auxiliary moving valve plate 131 is configured with a auxiliary valve inlet 1314. The softening connection hole 1322 is connected to the soft water inlet 119. 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.

[0239] It can be understood that, by driving the secondary spool 134 to move to the first secondary valve position through the secondary drive part 135, the secondary valve water inlet 1314 and the softening connection hole 1322 are communicated to form a backwashing flow channel, the backwashing flow channel can be communicated with the raw water inlet 113 and the soft water inlet 119, so that the raw water inlet 113, the backwashing flow channel and the soft water inlet 119 are communicated, and the raw water can flow into the softening device 190 along the raw water inlet 113, the backwashing flow channel and the soft water inlet 119.

[0240] It should be noted that the secondary valve water inlet 1314 can be communicated with the secondary cavity 112, and the secondary cavity 112 is communicated with the raw water inlet 113 through the main spool 124, so that the raw water inlet 113, the secondary cavity 112, the secondary valve water inlet 1314, the softening connection hole 1322 and the soft water inlet 119 are communicated, and the raw water can flow along the path of the raw water inlet 113, the secondary cavity 112, the secondary valve water inlet 1314, the softening connection hole 1322 and the soft water inlet 119.

[0241] In the backwashing mode, the backwashing flow channel is communicated with the soft water inlet 119 and the secondary cavity 112, and the secondary cavity 112 is communicated with the raw water inlet 113, so that the raw water inlet 113, the secondary cavity 112, the backwashing flow channel and the soft water inlet 119 are communicated. The raw water can flow along the path of the raw water inlet 113, the secondary cavity 112, the backwashing flow channel and the soft water inlet 119, and when the raw water flows into the secondary cavity 112, part of the raw water flows along the path of the backwashing flow channel and the soft water inlet 119, and the other part of the raw water flows to the soft water outlet 114, so that the user can obtain the raw water at the soft water outlet 114, and the user can still have water available when the soft water valve is in the backwashing state.

[0242] It should be noted that the backwashing mode and the salt suction mode are both communicated with the first blowdown flow channel 127 to discharge water outward, that is, in the backwashing mode and the salt suction mode, the state of the main spool 124 is the same, which can simplify the structure of the main valve assembly 120 and the flow path arrangement in the soft water valve.

[0243] It should be noted that in the salt suction mode and the backwashing mode, the path of the raw water flowing into the secondary cavity 112 is the same, and the main valve assembly 120 is used to communicate the raw water inlet 113 and the secondary cavity 112, and the main valve assembly 120 is also used to disconnect the raw water inlet 113 and the main cavity 111, which can simplify the structure of the main valve assembly 120 and the flow path arrangement in the soft water valve.

[0244] It can also be understood that in the backwash mode and the salt suction mode, the state of the main valve assembly 120 is the same, and water is drained to the outside of the water softener valve through the main valve assembly 120, but the flow path of the water is not limited to the first drain flow channel 127 described above, but can also be a structure not shown in the figure, such as the technical solution of “the main static valve piece 122 is provided with two drain holes” described above. For details, please refer to the above description, which will not be repeated here. That is, in the process of switching from the salt suction mode to the backwash mode, the state of the auxiliary valve assembly 130 can be controlled, and the state of the main valve assembly 120 can remain unchanged.

[0245] It should be noted that in the backwash mode and the water production mode, the state of the auxiliary valve assembly 130 can be the same, and the auxiliary valve core 134 is used to communicate the soft water inlet 119 and the auxiliary cavity 112, and the switching of the position of the main valve core 124 can realize the switching of the water softener valve between the water production mode and the backwash mode. In the backwash mode, the auxiliary valve assembly 130 communicates the soft water inlet 119 and the auxiliary cavity 112 in order to make the raw water in the auxiliary cavity 112 flow to the softening device 190 through the soft water inlet 119; in the water production mode, the auxiliary valve assembly 130 communicates the soft water inlet 119 and the auxiliary cavity 112 in order to make the soft water at the soft water inlet 119 flow to the soft water outlet 114 through the auxiliary cavity 112. By sharing one state of the auxiliary valve core 134 in the backwash mode and the water production mode, the structure of the auxiliary valve assembly 130 can be simplified.

[0246] The above describes the backwash mode, and the forward wash mode is described below.

[0247] Reference Figures 9 to 14 and Figures 28 to 30 As shown in the drawings, the valve housing 110 is provided with a drain port 115. In the forward wash mode, the auxiliary driving part 135 is used to drive the auxiliary valve core 134 to move to the forward wash flow channel 138 to communicate, and the forward wash flow channel 138 communicates the soft water inlet 119 and the drain port 115. The auxiliary driving part 135 drives the auxiliary valve core 134 to move to the fourth auxiliary valve position, so that the forward wash flow channel 138 is communicated. At this time, the main water production flow channel 126 of the main valve core 124 communicates the main cavity 111 and the raw water inlet 113, so that the raw water can flow along the path of the raw water inlet 113, the main cavity 111, the raw water outlet 118 and the soft water inlet 119, and the forward wash flow channel 138 communicates the soft water inlet 119 and the drain port 115, so that the water can flow along the path of the soft water inlet 119 and the drain port 115, so as to realize the discharge of sewage from the valve housing 110 in the forward wash mode.

[0248] It can be understood that the main valve core 124 is in the first main valve position, and the switching of the position of the auxiliary valve core 134 realizes the switching of the water softener valve among the water making mode, the water filling mode and the forward washing mode. The main valve core 124 is in the first main valve position in the water making mode, the water filling mode and the forward washing mode, that is, the state of the main valve core 124 is the same, and the path of water flowing from the raw water inlet 113 to the soft water inlet 119 is the same. At this time, the auxiliary valve core 134 is driven by the auxiliary driving part 135 to switch the position, that is, the switching of the water softener valve among the water making mode, the water filling mode and the forward washing mode is realized, so that the control of the water softener valve is more simple, and the structure of the water softener valve is simplified.

[0249] The auxiliary valve core 134 includes an auxiliary static valve piece 132 and an auxiliary dynamic valve piece 131, the auxiliary dynamic valve piece 131 is connected to the auxiliary driving part 135, the auxiliary static valve piece 132 is fixed with the valve housing 110, the auxiliary static valve piece 132 is configured with a softening connection hole 1322 and an auxiliary valve blowdown hole 1321, the softening connection hole 1322 is communicated with the soft water inlet 119, the auxiliary valve blowdown hole 1321 is communicated with the blowdown outlet 115, and the softening connection hole 1322 and the auxiliary valve blowdown hole 1321 are communicated through the auxiliary valve core 134 to form a forward washing flow channel 138.

[0250] It can be understood that the forward washing flow channel 138 formed by the communication of the softening connection hole 1322 and the auxiliary valve blowdown hole 1321 can communicate the soft water inlet 119 and the blowdown outlet 115, so that the soft water inlet 119, the forward washing flow channel 138 and the blowdown outlet 115 are communicated. In the forward washing mode, the raw water flows into the softening device 190 through the raw water inlet 113, the main cavity 111 and the raw water outlet 118, the forward washing operation is performed on the softening device 190, the sewage after the cleaning of the softening device 190 is discharged from the soft water outlet 114, then the sewage flows along the path of the soft water inlet 119, the forward washing flow channel 138 and the blowdown outlet 115 and is discharged from the valve housing 110, so that the blowdown in the forward washing mode is realized.

[0251] The auxiliary dynamic valve piece 131 is configured with an auxiliary valve water inlet 1314, the auxiliary valve water inlet 1314 communicates with the auxiliary cavity 112, and the softening connection hole 1322 communicates with the auxiliary valve blowdown hole 1321 through the auxiliary valve water inlet 1314 to form the forward washing flow channel 138.

[0252] It can be understood that the softened connection hole 1322 is communicated with the auxiliary valve water inlet 1314 and the auxiliary valve drain hole 1321, and the auxiliary valve water inlet 1314 is communicated with the auxiliary cavity 112, so that the water at the soft water inlet 119 can flow to the drain hole 115 along the forward washing flow channel 138, and can flow to the auxiliary cavity 112 along the softened connection hole 1322 and the auxiliary valve water inlet 1314. Since the backwashing operation of the soft water valve has been performed before the forward washing mode, the sewage generated in the forward washing mode has a low salt content and can be used. When the user needs to use water in the forward washing mode, the water in the auxiliary cavity 112 is discharged through the soft water outlet 114 for the user to use.

[0253] It should be noted that the water at the soft water inlet 119 can also flow into the auxiliary cavity 112 along the softened connection hole 1322 and the auxiliary valve water inlet 1314, and then part of the water in the auxiliary cavity 112 flows along the path of the auxiliary valve water inlet 1314 and the auxiliary valve drain hole 1321 to the drain hole 115, and the other part flows to the soft water outlet 114, so that the user still has water available in the forward washing mode.

[0254] It should be noted that in the forward washing mode, the softened connection hole 1322 is communicated with the auxiliary valve water inlet 1314, and at this time the softened connection hole 1322 and the auxiliary valve water inlet 1314 are used to form the forward washing flow channel 138 and the auxiliary water production flow channel 136. That is, the auxiliary valve core 134 plays a role of communicating the soft water inlet 119 and the auxiliary cavity 112 in the forward washing mode and the water production mode, and the auxiliary valve core 134 has a flow channel formed by the communication of the softened connection hole 1322 and the auxiliary valve water inlet 1314, but in the forward washing mode, the auxiliary valve core 134 is also communicated with the auxiliary valve drain hole 1321 and the auxiliary valve water inlet 1314.

[0255] In the forward washing mode, the forward washing flow channel 138 communicates the soft water inlet 119 with the drain passage 1114 of the valve housing 110, the drain hole 115 is formed at the end of the drain passage 1114, the raw water outlet 118 is communicated with the raw water inlet 113, and the raw water in the soft water valve enters the softening device 190 through the raw water outlet 118. The water in the softening device 190 enters the soft water valve through the soft water inlet 119, is discharged through the forward washing flow channel 138 of the auxiliary valve core 134 and the drain passage 1114 of the valve housing 110, and realizes the discharge of the sewage for cleaning the softening device 190.

[0256] It can be understood that, in the case that the main valve core 124 is provided with the main water production flow channel 126, in the forward washing mode, the raw water outlet 118 and the raw water inlet 113 are communicated through the main water production flow channel 126. It can also be understood that, in the forward washing mode, the state of the main valve core 124 is the same as that in the water production mode, that is, the main valve core 124 is in the first main valve position. When the main valve core 124 is in the first main valve position, the water production mode and the forward washing mode can be switched by adjusting the state of the auxiliary valve core 134.

[0257] The auxiliary driving part 135 is used to drive the auxiliary valve core 134 to rotate to communicate or disconnect the forward washing flow channel 138, that is, the auxiliary driving part 135 can realize the state switching of the auxiliary valve core 134 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.

[0258] Among them, after the water softener executes the salt suction mode, the softening device 190 needs to be cleaned, and the cleaning mode of the softening device 190 can be at least one of the above-mentioned backwashing mode and forward washing mode. When the cleaning mode includes the backwashing mode or the forward washing mode, the softening device 190 can be cleaned by the backwashing mode or the forward washing mode after the salt suction mode is executed; when the cleaning mode includes the backwashing mode and the forward washing mode, after the salt suction mode is ended, the backwashing mode or the forward washing mode can be executed first, which can be selected as needed. In some cases, after the salt suction mode, the backwashing mode is executed first, and then the forward washing mode is executed.

[0259] 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 all provided with openings corresponding to the holes and communicated with the holes on the valve housing 110, so as to ensure that water can flow out through the holes of the static valve piece.

[0260] The above describes the flow paths corresponding to the modes of the water softener. Next, the control mode of the water softener is described.

[0261] Based on the above, the main valve assembly 120 includes two main valve positions, and the auxiliary valve assembly 130 includes multiple auxiliary valve positions. The positional relationship between the main valve assembly 120 and the auxiliary valve assembly 130 is described.

[0262] It can be understood that the main driving part 125 is used to drive the main valve core 124 to switch between the first main valve position and the third main valve position, and the auxiliary driving part 135 is used to drive the auxiliary valve core 134 to switch between the multiple auxiliary valve positions, so as to switch the water softener between the water production mode, the water injection mode, the salt suction mode and the cleaning mode.

[0263] Reference Figure 17 , Figure 20 , Figure 23 , Figure 26 and Figure 29As shown, the main valve core 124 switches between the first main valve position and the third main valve position, that is, the position of the main valve core 124 is the same in at least two modes, which can simplify the regulation mode of the main valve core 124.

[0264] In some cases, as shown in Figure 17 , Figure 20 and Figure 29 , in the first main valve position, the main water flow channel 126 of the main valve core 124 is connected to the main cavity 111 and the raw water inlet 113, and at the same time, the main cavity 111 is connected to the raw water outlet 118, that is, the raw water in the raw water inlet 113 can be transported to the raw water outlet 118 through the main valve core 124 to realize the process of transporting raw water to the softening device 190, and at this time, the position switching of the auxiliary valve core 134 is used to switch the water softener valve between the water production mode and the water injection mode.

[0265] When the cleaning mode includes the forward washing mode, the main valve core 124 is in the first main valve position, and the position switching of the auxiliary valve core 134 is used to switch the water softener valve to the forward washing mode. The structure of the “main water flow channel 126” can refer to the above description of the water production mode, the water injection mode and the forward washing mode, for example, the main valve water inlet 1211 of the main driving valve piece 121 and the main valve water hole 1221 of the main static valve piece 122 are connected to form the main water flow channel 126.

[0266] In other cases, as shown in Figure 23 and Figure 26 , in the third main valve position, the first drain flow channel 127 of the main valve core 124 is connected, the main water flow channel 126 is disconnected, and the first drain flow channel 127 is connected to the raw water outlet 118 and the drain passage 1114 of the valve housing 110 to discharge sewage along the raw water outlet 118, the first drain flow channel 127 and the drain passage 1114. In the third main valve position, the main valve core 124 is used to guide the sewage in the softening device 190 out. In the mode that needs to discharge sewage, the main valve core 124 can be switched to the third main valve position, at this time, the raw water can be transported to the auxiliary cavity 112 through the main valve core 124, and then the water flow is controlled through the auxiliary valve core 134 to realize the operation of sending water to the salt tank 200 and sending water to the softening device 190.

[0267] When the cleaning mode includes the backwash mode, the main valve core 124 is in the third main valve position, and the switching of the position of the auxiliary valve core 134 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 main valve core 124 delivers raw water to the auxiliary cavity 112, the auxiliary valve core 134 delivers water at the auxiliary cavity 112 to the softening device 190, and the main valve core 124 guides the sewage in the softening device 190 out. In these two modes, the flow channels communicated by the auxiliary valve core 134 are different. In the salt suction mode, the first salt suction flow channel 1341 and the second salt suction flow channel 1342 of the auxiliary valve core 134 are communicated, and in the backwash mode, the backwash flow channel of the auxiliary valve core 134 is communicated.

[0268] The above describes two positions of the main valve assembly 120. Next, the modes will be described in combination with the positions of the main valve assembly 120 and the auxiliary valve assembly 130.

[0269] Reference is made to Fig. 1 and Fig. 2. Figure 18 As shown, in the water production mode, the auxiliary valve core 134 is in the first auxiliary valve position, and the main valve core 124 is in the first main valve position. The main valve core 124 is used to guide water to the softening device 190, and the auxiliary valve core 134 is used to make the soft water inlet 119 communicated with the soft water outlet 114, so as to ensure the soft water outlet. In addition, the auxiliary valve core 134 is also used to disconnect the soft water inlet 119 from other flow channels, so as to avoid the water in other flow channels polluting the soft water.

[0270] Reference is made to Fig. 1 and Fig. 2. Figure 21 As shown, in the water injection mode, the auxiliary valve core 134 is in the second auxiliary valve position, and the main valve core 124 is in the first main valve position. The main valve core 124 is used to guide water to the softening device 190, and the auxiliary valve core 134 is used to guide the soft water in the softening device 190 into the salt tank connecting port 1110. In the second auxiliary valve position, the water injection flow channel 137 of the auxiliary valve core 134 is communicated, and the water injection flow channel 137 communicates the soft water inlet 119 with the salt tank connecting port 1110. In addition, in the second auxiliary valve position, the auxiliary valve core 134 also communicates the soft water inlet 119 and the auxiliary cavity 112, so that the water at the soft water inlet 119 can flow into the auxiliary cavity 112, and then the water can flow from the auxiliary cavity 112 to the soft water outlet 114, so as to ensure that the user has water available in the water injection mode.

[0271] Reference is made to Fig. 1 and Fig. 2. Figure 24As shown, in the salt draw mode, the sub-valve core 134 is at the third sub-valve position, and the main valve core 124 is at the third main valve position. The main valve core 124 is used to isolate the raw water inlet 113 from the main cavity 111, and the sub-valve core 134 is used to pass the raw water into the jet device 160, and under the flow power of the raw water, draw the salt solution in the salt tank connecting port 1110 into the jet device 160, and send the mixed solution in the jet device 160 into the softening device 190, and the water in the softening device 190 is discharged along the valve housing 110 through the main valve core 124. In the third sub-valve position, the first salt draw flow channel 1341 and the second salt draw flow channel 1342 of the sub-valve core 134 are communicated, the jet inlet 161 of the jet flow channel is communicated with the sub-cavity 112 through the first salt draw flow channel 1341, the suction inlet 163 of the jet flow channel is communicated with the salt tank connecting port 1110, and the jet outlet 162 of the jet flow channel is communicated with the soft water inlet 119 through the second salt draw flow channel 1342. In the salt draw mode, the main valve core 124 is also used to communicate the raw water inlet 113 with the sub-cavity 112, so that the raw water can flow into the sub-cavity 112. In addition to flowing into the jet device 160, the raw water in the sub-cavity 112 can also flow into the soft water outlet 114, so that the user has raw water available in the salt draw mode, and the sub-valve core 134 is also used to separate the soft water inlet 119 and the sub-cavity 112, which can avoid the pollution of the salt water at the soft water inlet 119 to the raw water in the sub-cavity 112.

[0272] Reference Figure 27 As shown, when the cleaning mode includes the backwashing mode, in the backwashing mode, the sub-valve core 134 is at the first sub-valve position, and the main valve core 124 is at the third main valve position. The sub-valve core 134 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 housing 110 through the main valve core 124. In the first sub-valve position, the backwashing flow channel of the sub-valve core 134 is communicated, and the backwashing flow channel communicates the soft water inlet 119 with the sub-cavity 112. The main valve core 124 is at the third main valve position, and the main valve core 124 isolates the raw water inlet 113 from the main cavity 111, and communicates the raw water inlet 113 with the sub-cavity 112, so that the raw water can enter the sub-cavity 112. Then part of the raw water flows into the softening device 190 from the sub-cavity 112, and the other part of the raw water flows into the soft water outlet 114, so that the user has water available when backwashing.

[0273] Reference Figure 30As shown, when the cleaning mode includes the forward washing mode, in the forward washing mode, the sub-valve core 134 is at the fourth sub-valve position, the main valve core 124 is at the first main valve position, the main valve core 124 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 housing 110 through the sub-valve core 134. In the third sub-valve position, the forward washing flow channel 138 of the sub-valve core 134 is communicated, and the forward washing flow channel 138 communicates the softened water inlet 119 and the blowdown passage 1114 of the valve housing 110. It should be noted that before the soft water valve is controlled to be in the forward washing mode, the soft water valve can be controlled to be in the reverse washing mode, that is, the soft water valve is first cleaned to reduce the salt content of the water in the soft water valve. Then control the soft water valve to be in the forward washing mode, at this time the salt content of the water in the soft water valve is already low, the user can use, the forward washing operation can be understood as a bottom-up cleaning step, that is, after the reverse washing mode, the water in the soft water valve is in a normal use state, so that in the forward washing mode, the user can use water.

[0274] When the soft water valve includes the water making mode, the water filling mode and the salt absorbing mode, the sub-driving part 135 is used to drive the sub-valve core 134 to rotate and switch between the first sub-valve position, the second sub-valve position and the third sub-valve position, the first sub-valve position, the second sub-valve position and the third sub-valve position are sequentially arranged along the circumference of the sub-valve core 134, facilitating the position adjustment of the sub-valve core 134. The cleaning mode includes the forward washing mode, and the sub-driving part 135 is used to drive the sub-valve core 134 to rotate and switch between the first sub-valve position, the second sub-valve position, the third sub-valve position and the fourth sub-valve position, the first sub-valve position, the second sub-valve position, the third sub-valve position and the fourth sub-valve position are sequentially arranged along the circumference of the sub-valve core 134.

[0275] For the state and function mode of the soft water valve, the structure of each flow channel is not described here, which can be combined with the above description of each mode.

[0276] During the operation of the soft water valve, the soft water valve is mainly in the water making mode. When the softening material in the softening device 190 needs to be regenerated, water is first filled into the salt tank 200, the water filling mode is executed, then the salt absorbing mode is executed, the mixed solution with the regeneration function is sent into the softening device 190, and then the cleaning mode is executed. When the cleaning mode includes the forward washing mode and the reverse washing mode, the reverse washing mode can be executed first, and then the forward washing mode can be executed.

[0277] In water production mode, the main valve core 124 is in the first main valve position, and the auxiliary valve core 134 is in the first auxiliary valve position. When water injection mode is required, the position of the main valve core 124 does not need to be adjusted, and the auxiliary valve core 134 is adjusted to the second 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 back to water production mode, the position of the main valve core 124 does not need to be adjusted, and the auxiliary valve core 134 can return to the first auxiliary valve position. After brine dissolution is completed, the brine suction mode is executed, and the main valve core 124 needs to be adjusted to the third main valve position, and the auxiliary valve core 134 needs to be adjusted to the third auxiliary valve position. Taking the backwash mode after brine suction mode as an example, at this time, the position of the main valve core 124 does not need to be adjusted, and the auxiliary valve core 134 is adjusted to the first auxiliary valve position. Then, the forward wash mode is executed, and the main valve core 124 needs to be adjusted to the first main valve position, and the auxiliary valve core 134 needs to be adjusted to the fourth auxiliary valve position to complete the regeneration process of the softening material. Finally, adjust the soft water valve to the water production mode and continue to perform the water production function.

[0278] In some cases, refer to Figure 44 As shown, the main valve core 124 also includes a second main valve position, which 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 124 blocks the raw water inlet 113 from the main chamber 111 and blocks the raw water inlet 113 from the secondary chamber 112. The secondary drive unit 135 controls the secondary valve core 134 to switch positions. At this time, the water from 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 134 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 134, making the position switching of the secondary valve core 134 easier. This can reduce the driving force provided by the secondary drive unit 135 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 softening valve.

[0279] The main valve core 124 is in the second main valve position, which can control the auxiliary drive unit 135 to drive the auxiliary valve core 134 to switch between multiple auxiliary valve positions. Before the auxiliary valve core 134 needs to switch positions, switching the position of the main valve core 124 to the second main valve position can reduce the resistance of water pressure to the position switching of the auxiliary valve core 134, making the position switching of the auxiliary valve core 134 more effortless and easier to operate.

[0280] Understandably, when switching from water production mode to water injection mode, the position of the main valve core 124 needs to be adjusted to the second main valve position first, and then the position of the auxiliary valve core 134 needs to be adjusted to the second auxiliary valve position. After the auxiliary valve core 134 is adjusted, the main valve core 124 returns to the first main valve position, and the water injection process can be executed. After the water injection is completed, the main valve core 124 is adjusted to the second main valve position again, and then the auxiliary valve core 134 returns to the first auxiliary valve position. Then the main valve core 124 is adjusted back to the first main valve position. At this time, the brine tank connection port 1110 is in the brine dissolving state, the soft water valve is in the water production mode, and the user can take water. After the salt dissolution is complete, the salt absorption mode is activated. First, the main valve core 124 is adjusted to the second main valve position, then the auxiliary valve core 134 is adjusted to the third auxiliary valve position, and then the main valve core 124 is adjusted back to the third main valve position to execute the salt absorption mode. After the salt absorption mode is completed, the system is switched to the backwash mode. First, the main valve core 124 is adjusted to the second main valve position, then the auxiliary valve core 134 is adjusted to the first auxiliary valve position, and then the main valve core 124 is adjusted back to the third main valve position to execute the backwash mode. After the backwash mode, the system is switched to the forward wash mode. First, the main valve core 124 is adjusted to the second main valve position, then the auxiliary valve core 134 is adjusted to the fourth auxiliary valve position, and then the main valve core 124 is adjusted back to the first main valve position to execute the forward wash mode. After the forward washing mode is completed, it is necessary to switch to the water production mode. First, adjust the main valve core 124 to the second main valve position, then adjust the auxiliary valve core 134 to the first auxiliary valve position, and then adjust the main valve core 124 to the first main valve position to produce water.

[0281] The above content describes the water production mode of the soft water valve, other functional modes for regenerating the softening material in the softening device 190, and the switching between modes. Based on the above technical solution, when the soft water valve is applied to a water softener, the user can obtain soft water with a single hardness from the water softener. That is, the hardness of the soft water obtained by the water softener is not convenient to adjust. Therefore, the following content provides a technical solution for adjustable soft water hardness.

[0282] Understandably, reference Figures 31 to 34 As shown, the valve body 110 has a raw water channel and a soft water channel. The raw water channel is located between the raw water inlet 113 and the main chamber 111, and the soft water channel is located between the soft water outlet 114 and the secondary chamber 112. A bypass valve 140 connects the raw water channel and the soft water channel, allowing them to be connected or disconnected. When the bypass valve 140 connects the raw water channel and the soft water channel, the raw water in the raw water inlet 113 can flow into the soft water channel under the inlet pressure, thereby adjusting the hardness of the water outlet 114 by introducing raw water into the soft water channel.

[0283] The bypass valve 140 is connected between the raw water channel and the soft water channel, and is installed flexibly, which helps to reduce the size of the soft water valve.

[0284] In some cases, the bypass valve 140 is connected between the raw water channel and the soft water channel when the soft water device does not produce water, and the user can obtain raw water from the soft water outlet 114.

[0285] The bypass valve 140 has various structures and can be selected as needed. As shown in Figure 34 The bypass valve 140 can be a disc valve, which is simple in structure and convenient to disassemble and assemble.

[0286] As shown in Figure 41 The first shell part 1140 of the valve housing 110 forms the raw water channel, the second shell part 1141 of the valve housing 110 forms the soft water channel, the first shell part 1140 is provided with a first communication port 1134 connected with the raw water channel, the second shell part 1141 is provided with a second communication port 1135 connected with the soft water channel, and the valve housing 110 further forms a bypass cavity, in which a bypass valve core 140 of the bypass valve 140 is located. The bypass valve core 140 is used to adjust the on-off of the first communication port 1134 and the second communication port 1135.

[0287] As shown in Figure 34 The bypass valve core 140 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, so that the bypass valve 140 is closed and the raw water channel and the soft water channel are disconnected. The bypass dynamic valve plate 141 can move to open the first bypass opening 1421 and the second bypass opening 1422, so that the bypass valve 140 is opened and the raw water channel and the soft water channel 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. The structure is simple and convenient to process.

[0288] The bypass dynamic valve plate 141 is connected to a bypass motor 143, which is used to drive the bypass dynamic valve plate 141 to rotate. By rotating the bypass dynamic valve plate 141, the state of the bypass valve 140 is switched.

[0289] As shown in Figure 32 and Figure 33As shown, the valve housing 110 is provided with a bypass cavity, in one form, 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 140 core can be installed in the opening of the bypass groove 1132, and the opening of the bypass groove 1132 is closed by a cover 1133 to form a bypass cavity, the structure of the bypass cavity 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 plate 142 is sealed and connected to the inner wall of the valve housing 110 through the bypass sealing ring 144.

[0290] Reference Figure 35 As shown, the user can also take raw water through the water softening valve, at this time, the main valve core 124 can be in the second main valve position.

[0291] Next, the structure of the valve housing 110 will be described.

[0292] Reference Figures 1 to 6 、 Figures 40 to 42 As shown, 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 cavity 111 and the auxiliary cavity 112. The third housing part 1142 is also formed with a raw water outlet 118 and a soft water inlet 119, and the raw water outlet 118 and the soft water inlet 119 are located on the same side of the third housing part 1142 to facilitate the installation of the softening device 190.

[0293] 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.

[0294] 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 cavity 111 and the auxiliary cavity 112 are arranged side by side, the main cavity 111 is located on the same side (right side) of the first housing part 1140, and the auxiliary cavity 112 is located on the same side (left side) of the second housing part 1141. The structure of the valve housing 110 is more reasonable.

[0295] The valve housing 110 (such as the third housing part 1142) is provided with a communication passage 1113 for communicating the raw water inlet 113 with the auxiliary cavity 112, and the communication passage 1113 is in on-off connection with the raw water inlet 113 through the main valve core 124, that is, whether the raw water inlet 113 is communicated with the auxiliary cavity 112 can be controlled. The outlet of the communication passage 1113 is communicated with the auxiliary cavity 112, and the inlet of the communication passage 1113 is in on-off connection with the raw water inlet 113 through the main valve core 124.

[0296] The valve shell 110 is provided with a softening connection port 1121 corresponding to and in communication with a softening connection hole 1322 of the auxiliary static valve plate 132. The softening connection port 1121 can communicate the softening connection hole 1322 with the soft water inlet 119. By switching the position of the auxiliary moving valve plate 131, the softening device 190 and other flow paths can be adjusted to be connected or disconnected. The softening connection port 1121 is located between the soft water inlet 119 and the auxiliary valve core 134, and is arranged adjacent to the auxiliary static valve plate 132, so as to facilitate the direct correspondence and communication between the softening connection hole 1322 and the softening connection port 1121. The auxiliary valve core 134 is located between the softening connection port 1121 and the auxiliary cavity 112, so that the auxiliary valve core 134 can control the communication between the softening connection port 1121 and the auxiliary cavity 112, that is, the communication between the auxiliary cavity 112 and the soft water inlet 119. The side of the softening connection hole 1322 facing the soft water inlet 119 can keep the softening connection hole 1322 in normal communication with the softening connection port 1121, that is, in normal communication with the soft water inlet 119, so as to simplify the structure of the auxiliary valve core 134. By controlling the rotation of the auxiliary moving valve plate 131, the softening connection hole 1322 can be switched between the state of being in communication with the auxiliary cavity 112 and the state of not being in communication with the auxiliary cavity 112. When the softening connection hole 1322 does not need to be in communication with the auxiliary cavity 112, the auxiliary moving valve plate 131 can block the softening connection hole 1322 and the auxiliary cavity 112.

[0297] The third shell part 1142 is further provided with a raw water outlet 118 and a soft water inlet 119. The third shell part 1142 is provided with a softening connection part 1143 for connecting the softening device 190. The softening device 190 can be connected to the valve shell 110 by at least one of screw connection, clamping, plug-in connection, fastener connection and the like. Referring to Figure 4 and Figure 5 The valve shell 110 is provided with external threads, and the softening device 190 is provided with internal threads. The softening device 190 is screwed to the valve shell 110 through the threaded structure, facilitating disassembly and assembly.

[0298] The third shell part 1142 is further provided with a salt suction and water injection port 1119 corresponding to and in communication with a salt suction and water injection hole 1324 of the auxiliary static valve plate 132. The salt suction and water injection port 1119 is in communication with the jet inlet 161 of the jet flow channel. The third shell part 1142 is further provided with a brine port 1120 corresponding to and in communication with a brine hole 1323 of the auxiliary static valve plate 132. The brine port 1120 can be in communication with the jet outlet 162 of the jet flow channel. By switching the position of the auxiliary moving valve plate 131, the jet flow channel and other flow paths can be adjusted to be connected or disconnected.

[0299] The auxiliary valve core 134 is located between the salt suction water inlet 1119 and the auxiliary cavity 112, so as to control the opening and closing of the salt suction water inlet 1119 and the auxiliary cavity 112, that is, to control the opening and closing between the auxiliary cavity 112 and the jet flow channel. The salt suction water inlet 1119 is located adjacent to the auxiliary static valve piece 132, so as to directly correspond to the communication between the salt suction water inlet 1119 and the salt suction water hole 1324, and to simplify the communication structure between the salt suction water inlet 1119 and the salt suction water hole 1324. The salt suction water hole 1324 is located towards the side of the salt suction water inlet 1119, so that the salt suction water hole 1324 and the salt suction water inlet 1119 can be kept in normal communication, and the structure of the auxiliary valve core 134 can be simplified. By controlling the rotation of the auxiliary dynamic valve piece 131, the salt suction water hole 1324 can be switched between the state of being communicated with the auxiliary cavity 112 and the state of not being communicated with the auxiliary cavity 112. When the salt suction water hole 1324 does not need to be communicated with the auxiliary cavity 112, the auxiliary dynamic valve piece 131 can block the salt suction water hole 1324 and the auxiliary cavity 112.

[0300] The salt water inlet 1120 is located adjacent to the auxiliary static valve piece 132, so as to directly correspond to the communication between the salt water inlet 1120 and the salt water hole 1323, and to simplify the communication structure between the salt water inlet 1120 and the salt water hole 1323. The salt water hole 1323 is located towards the side of the salt water inlet 1120, so that the salt water inlet 1120 and the salt water hole 1323 can be kept in normal communication, and the structure of the auxiliary valve core 134 can be simplified. By controlling the rotation of the auxiliary dynamic valve piece 131, the salt water hole 1323 can be switched between the state of being communicated with the jet flow channel and the state of not being communicated with the jet flow channel. When the salt water hole 1323 does not need to be communicated with the jet flow channel, the auxiliary dynamic valve piece 131 can block the salt water hole 1323 and the jet flow channel.

[0301] The valve housing 110 (such as the third housing part 1142) is provided with at least one of the first blow-off opening 1125 and the second blow-off opening 1124. The first blow-off opening 1125 corresponds to and is communicated with the main valve blow-off hole 1222. By controlling the position of the main dynamic valve piece 121, the opening and closing of the first blow-off opening 1125 and the corresponding flow channel can be realized, and sewage can be discharged through the first blow-off opening 1125. The second blow-off opening 1124 corresponds to and is communicated with the auxiliary valve blow-off hole 1321. By controlling the position of the auxiliary dynamic valve piece 131, the opening and closing of the second blow-off opening 1124 and the corresponding flow channel can be realized, and sewage can be discharged through the second blow-off opening 1124. The valve housing 110 is further provided with a blow-off channel 1114. The blow-off channel 1114 is communicated with at least one of the first blow-off opening 1125 and the second blow-off opening 1124. The end of the blow-off channel 1114 forms a blow-off port 115, so that the sewage can be discharged along the blow-off port 115, and the blow-off pipeline can be simplified. A flow limiting piece is arranged in the blow-off channel 1114 to adjust the blow-off flow rate. The blow-off channel 1114 is located above the valve housing 110.

[0302] It should be noted that during the regeneration of the softening 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 1114, 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.

[0303] refer to Figure 41 and Figure 42 As shown, when the valve housing 110 is provided with a drain channel 1114, the valve housing 110 includes a housing and a cover 1116 connected to the housing. The housing forms a drain groove 1117, and the drain groove 1117 has a first opening along its length. The cover 1116 covers the housing to close the first opening, thus forming a drain channel 1114 inside the valve housing 110. The end of the drain channel 1114 forms a drain outlet 115. The function of the drain channel 1114 is the same as described above and will not be repeated. The structure of the drain channel 1114 is not limited to the aforementioned structure and can be selected as needed. In the manufacturing of the soft water valve, the drain groove 1117 can be formed by directly opening the corresponding groove in the valve body 110. By covering the drain groove 1117 with the cover 1116 to close the first opening, the drain channel 1114 can be formed without forming an internal flow channel inside the valve body 110, making the mold manufacturing of the soft water valve head simpler and more convenient.

[0304] The valve housing 110 is provided with a main chamber communication hole 116, which connects the main chamber 111 and the raw water outlet 118. This allows water in the main chamber 111 to flow through the main chamber communication hole 116 to the raw water outlet 118, thus injecting water into the softening device 190. Water at the raw water outlet 118 can flow through the main chamber communication hole 116 into the main chamber 111. For example, wastewater from the softening device 190 can be discharged into the main chamber 111 and then discharged from the valve housing 110 through the drain channel 1114, thus performing a drain operation.

[0305] The main cavity communication hole 116 is formed in the wall surface of the main cavity 111, and the main valve core 124 is located between the main cavity communication hole 116 and the raw water inlet 113, so that the main valve core 124 can control the on-off of the raw water inlet 113 and the main cavity communication hole 116, and also can control whether the raw water can flow into the softening device 190 through the main cavity communication hole 116 and the raw water outlet 118, thereby realizing the control of water injection of the softening device 190. In the salt absorption mode and the backwashing mode, the main valve core 124 can block the main cavity 111 and the raw water inlet 113, that is, the main cavity communication hole 116 and the raw water inlet 113, so that the sewage in the main cavity 111 flowing through the raw water outlet 118 and the main cavity communication hole 116 cannot flow to the raw water inlet 113, avoiding pollution of the raw water at the raw water inlet 113, and making the sewage flow to the sewage discharge channel 1114 through the main valve core 124, and finally discharged from the valve shell 110.

[0306] The valve shell 110 is configured with a water outlet flow channel 1112, and the wall surface of the auxiliary cavity 112 is provided with an auxiliary cavity communication hole 1111. The water outlet flow channel 1112 communicates the auxiliary cavity communication hole 1111 and the soft water outlet 114, and the auxiliary cavity communication hole 1111 is adjusted in communication and interruption with the soft water inlet 119 by the auxiliary valve core 134. The auxiliary cavity 112 is always in communication with the water outlet flow channel 1112 through the auxiliary cavity communication hole 1111, so that the water in the auxiliary cavity 112 can flow to the soft water outlet 114. The auxiliary cavity 112 can also be communicated with other flow channels through the switching of the flow path of the auxiliary valve core 134, so as to realize different functions. That is, the water in the auxiliary cavity 112 can flow along at least two flow paths. One of the flow paths is fixed as the flow path of the auxiliary cavity 112 to the soft water outlet 114, and the other flow path changes according to the control switching of the auxiliary valve core 134. As long as there is available water in the auxiliary cavity 112, there is available water at the soft water outlet 114. The auxiliary valve core 134 is arranged between the auxiliary cavity communication hole 1111 and the soft water inlet 119, so that the auxiliary valve core 134 can control the communication and interruption between the auxiliary cavity communication hole 1111 and the soft water inlet 119. In the salt absorption mode, the auxiliary valve core 134 can block the auxiliary cavity communication hole 1111 and the soft water inlet 119, so as to avoid the salt water at the soft water inlet 119 flowing to the auxiliary cavity communication hole 1111, and ensure that the water flowing to the soft water outlet 114 through the auxiliary cavity communication hole 1111 is not polluted by the salt water.

[0307] The auxiliary cavity communication hole 1111 and the soft water inlet 119 are located on the two sides of the auxiliary valve core 134, so as to facilitate the auxiliary valve core 134 to control the communication and interruption between the auxiliary cavity communication hole 1111 and the soft water inlet 119.

[0308] It should be noted that the "two sides" in the "two sides of the auxiliary valve core 134" mentioned herein have the same meaning as the "two sides" in the "two sides of the auxiliary valve core 134" mentioned in the above, and will not be repeated.

[0309] The auxiliary cavity communication hole 1111 and the soft water inlet 119 are located on the two sides of the auxiliary valve core 134, so as to facilitate the auxiliary valve core 134 to control the communication and interruption between the auxiliary cavity communication hole 1111 and the soft water inlet 119.Figure 1 and Figure 2 As shown, the water outlet channel is formed, for example, at the front end of the secondary cavity 112.

[0310] Based on the above, the water softener is connected to the user's main pipeline via a water softener valve. The design concept of the water softener valve in this embodiment is that two chambers, a main chamber 111 and a secondary chamber 112, are formed within the valve housing 110. Each chamber is equipped with a valve assembly, namely, the main chamber 111 is equipped with a main valve assembly 120, and the secondary chamber 112 is equipped with a secondary valve assembly 130. The main valve assembly 120 and the secondary valve assembly 130 cooperate to realize the function of the water softener valve, which can reduce the size of the water softener valve, help increase the soft water output flow rate of the water softener valve, and simplify the structure of the valve plate.

[0311] The main chamber 111 and the auxiliary chamber 112 have basically the same internal space and structure. The difference between the two chambers lies in the structure, number, and position of the openings, meaning that the main chamber 111 and the auxiliary chamber 112 have different functions. The two chambers have a circular structure, with the left and right chambers arranged horizontally. The axial direction of the chambers (corresponding to the direction of the rotation axis of the valve assembly) is horizontal and perpendicular to the resin tank connected to the bottom. Correspondingly, the resin tank is placed vertically in the water softener.

[0312] The above content describes the structure of valve housing 110. The following refers to... Figures 7 to 30 as well as Figure 40 The structure of the main valve assembly 120 and the auxiliary valve assembly 130 is described.

[0313] refer to Figure 7 , Figure 9 , Figure 11 and Figure 12 As shown, the main valve assembly 120 includes a main valve core 124 and a main drive unit 125. The main valve core 124 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, and the active valve plate 121 is rotatably disposed in the main cavity 111.

[0314] In different modes of the soft water valve, the hole structure of the main stationary valve plate 122 is located in the groove of the active valve plate 121 (the groove here can be the aforementioned first groove of the main valve or the process groove) when projected onto the active valve plate 121. By sealing the hole structure of the main stationary valve plate 122 through the groove, the sealing effect of the hole structure of the main stationary valve plate 122 can be improved, and the contact area between the main stationary valve plate 122 and the active valve plate 121 can be reduced, thereby reducing the friction between the active valve plate 121 and the main stationary valve plate 122. This facilitates the driving of the active valve plate 121 to rotate relative to the main stationary valve plate 122. Furthermore, the groove is connected to the space on one side of the main stationary valve plate 122 through the hole structure of the main stationary valve plate 122, allowing water to enter the groove, which can play a role in balancing water pressure and balancing the pressure of the active valve plate 121 and the main stationary valve plate 122.

[0315] The main active valve sheet 121 is provided with a main valve water inlet 1211 and a main valve first groove 1212, and the main static valve sheet 122 is provided with a main valve water inlet hole 1221.

[0316] In some cases, the main static valve sheet 122 is provided with a main valve blowdown hole 1222, and in some other cases, the main static valve sheet 122 is provided with a main-vice connecting hole 1223.

[0317] In some other cases, the main active valve sheet 121 is further provided with a main valve second groove 1213. It can be understood that the main valve second groove 1213 can be a main valve process groove.

[0318] For example, the main valve water inlet 1211, the main valve first groove 1212 and the main valve second groove 1213 are sequentially arranged along the circumference of the main active valve sheet 121, which facilitates the rotation control of the main active valve sheet 121; the main valve water inlet hole 1221, the main valve blowdown hole 1222 and the main-vice connecting hole 1223 are sequentially arranged along the circumference of the main static valve sheet 122, which facilitates the cooperation of the holes of the main static valve sheet 122 with the main active valve sheet 121.

[0319] The opening area of the main valve process groove is greater than or equal to the opening area of the hole structure of the main static valve sheet 122, which ensures that the groove structure can surround the hole structure, so that the hole structure has better sealing performance and can avoid water leakage.

[0320] For example, as shown in Figure 17 , Figure 20 and Figure 29 , in the water production mode, the water injection mode and the forward washing mode, the main valve water inlet 1211 and the main valve water inlet hole 1221 are communicated to form a main water production flow channel 126, which communicates the raw water inlet and the main cavity 111, so that the raw water can flow into the main cavity 111. At this time, the main-vice connecting hole 1223 of the main static valve sheet 122 is located in the main valve second groove 1213 in the orthographic projection of the main active valve sheet 121, that is, the main valve water inlet 1211 and the main valve first groove 1212 are both disconnected with the main-vice connecting hole 1223, and the main valve blowdown hole 1222 is located in the main valve first groove 1212 in the orthographic projection of the main active valve sheet 121, that is, the main valve water inlet 1211 and the main valve second groove 1213 are both disconnected with the main-vice connecting hole 1223. By closing the main-vice connecting hole 1223 through the main valve second groove 1213 and closing the main valve blowdown hole 1222 through the main valve first groove 1212, the sealing effect of the main-vice connecting hole 1223 and the main valve blowdown hole 1222 can be improved.

[0321] For example, the opening area of ​​the second groove 1213 of the main valve is greater than or equal to the opening area of ​​the main-auxiliary connection hole 1223. This ensures that the second groove 1213 of the main valve can surround the main-auxiliary connection hole 1223, resulting in better sealing of the main-auxiliary connection hole 1223 and preventing water leakage.

[0322] refer to Figure 23 and Figure 26 As shown, in both brine suction and backwashing modes, the main valve inlet 1221 is connected to the main-supplement connection hole 1223 via the main valve first groove 1212. Raw water from the raw water inlet enters the secondary chamber through the main valve inlet 1221, the main valve first groove 1212, and the main-supplement connection hole 1223. Part of the space in the main valve inlet 1221 is connected to the main valve first groove 1212, and part of the space in the main valve inlet 1221 corresponds to and is closed by the main valve second groove 1213. The main valve drain hole 1222 is connected to the main valve inlet 1211.

[0323] refer to Figure 8 , Figure 10 , Figure 13 and Figure 14 As shown, the secondary valve assembly 130 includes a secondary valve core 134 and a secondary drive unit 135. The secondary valve core 134 includes a secondary stationary valve plate 132 and a secondary driving valve plate 131. The secondary stationary valve plate 132 is fixed in the secondary cavity 112 of the valve housing 110, and the secondary driving valve plate 131 is rotatably disposed in the secondary cavity 112.

[0324] In different modes of the soft water valve, at least part of the hole structure of the auxiliary stationary valve plate 132 is located in the groove of the auxiliary moving valve plate 131 (the groove here can be the auxiliary valve process groove, or the aforementioned auxiliary valve first groove) when projected onto the auxiliary moving valve plate 131. Taking the auxiliary valve process groove as an example, by sealing the hole structure of the auxiliary stationary valve plate 132 through the auxiliary valve process groove, the sealing effect of the hole structure of the auxiliary stationary valve plate 132 can be improved, the contact area between the auxiliary stationary valve plate 132 and the auxiliary moving valve plate 131 can be reduced, and the friction between the auxiliary moving valve plate 131 and the auxiliary stationary valve plate 132 can be reduced, making it easier to drive the auxiliary moving valve plate 131 to rotate relative to the auxiliary stationary valve plate 132. Moreover, the auxiliary valve process groove is connected to the space on one side of the auxiliary stationary valve plate 132 through the hole structure of the auxiliary stationary valve plate 132, so that water can enter the auxiliary valve process groove, which can play a role in balancing water pressure and balancing the pressure of the auxiliary moving valve plate 131 and the auxiliary stationary valve plate 132.

[0325] Among them, reference Figure 13 and Figure 14 As shown, the auxiliary valve plate 131 is provided with an auxiliary valve inlet 1314 and an auxiliary valve first groove 1311; the auxiliary stationary valve plate 132 is provided with a softening connection hole 1322, a brine hole 1323 and a brine suction and water injection hole 1324.

[0326] In some cases, the auxiliary static valve plate 132 is provided with an auxiliary valve blowdown hole 1321.

[0327] In some cases, the auxiliary dynamic valve plate 131 is provided with one or more of an auxiliary valve second groove 1312, an auxiliary valve third groove 1313, an auxiliary valve fourth groove 1315, and an auxiliary valve fifth groove 1316. It can be understood that the auxiliary valve process groove can be any one or more of the auxiliary valve second groove 1312, the auxiliary valve third groove 1313, the auxiliary valve fourth groove 1315, and the auxiliary valve fifth groove 1316, or other groove structures other than the auxiliary valve second groove 1312, the auxiliary valve third groove 1313, the auxiliary valve fourth groove 1315, and the auxiliary valve fifth groove 1316.

[0328] For example, the auxiliary valve first groove 1311, the auxiliary valve second groove 1312, the auxiliary valve third groove 1313, the auxiliary valve water inlet 1314, the auxiliary valve fourth groove 1315, and the auxiliary valve fifth groove 1316 are sequentially arranged along the circumference of the auxiliary dynamic valve plate 131, facilitating the rotation control of the auxiliary dynamic valve plate 131; the auxiliary valve blowdown hole 1321, the softening connection hole 1322, and the salt water injection hole 1324 are sequentially arranged along the circumference of the auxiliary static valve plate 132, facilitating the cooperation of the holes of the auxiliary static valve plate 132 with the auxiliary dynamic valve plate 131.

[0329] The opening area of the auxiliary valve process groove is greater than or equal to the opening area of the hole structure of the auxiliary static valve plate 132, ensuring that the groove structure can surround the hole structure, making the hole structure better closed, and avoiding the occurrence of water leakage.

[0330] In some cases, the auxiliary valve first groove 1311 extends along the radial direction of the auxiliary dynamic valve plate 131, and by rotating the auxiliary dynamic valve plate 131, the auxiliary valve first groove 1311 switches between the state of connecting or disconnecting the salt water hole 1323 and the softening connection hole 1322. During the movement of the auxiliary valve first groove 1311, the auxiliary valve first groove 1311 can be always connected with the salt water hole 1323, or can be adjusted to be connected or disconnected. When the auxiliary valve first groove 1311 can be always connected with the salt water hole 1323, the salt water hole 1323 can be at the center of the auxiliary dynamic valve plate 131.

[0331] In the water production mode, the secondary valve water inlet 1314 and the softening connection hole 1322 are communicated to form a secondary water production flow channel 136, and the secondary water production flow channel 136 is communicated with the soft water inlet 119 and the secondary cavity 112, so that the water at the soft water inlet 119 can flow into the secondary cavity 112. At this time, the secondary valve drain hole 1321 of the secondary valve spool 132 is located in the fourth recess 1315 of the secondary valve spool 131 in the orthographic projection, that is, the secondary valve water inlet 1314 is disconnected with the secondary valve drain hole 1321, the salt water hole 1323 is located in the first recess 1311 of the secondary valve spool 131 in the orthographic projection of the primary valve spool 121, that is, the secondary valve water inlet 1314 and other recess structures of the secondary valve spool 131 are disconnected with the salt water hole 1323, the salt suction and water injection hole 1324 is located in the third recess 1313 of the secondary valve spool 131 in the orthographic projection of the primary valve spool 121, that is, the secondary valve water inlet 1314 and other recess structures of the secondary valve spool 131 are disconnected with the salt suction and water injection hole 1324, the secondary valve drain hole 1321 is closed through the fourth recess 1315 of the secondary valve, the salt water hole 1323 is closed through the first recess 1311 of the secondary valve, and the salt suction and water injection hole 1324 is closed through the third recess 1313 of the secondary valve, which can improve the sealing effect of the secondary valve drain hole 1321, the salt water hole 1323 and the salt suction and water injection hole 1324.

[0332] For example, the opening area of the fourth recess 1315 of the secondary valve is greater than or equal to the opening area of the secondary valve drain hole 1321. It is ensured that the fourth recess 1315 of the secondary valve can surround the secondary valve drain hole 1321, so that the secondary valve drain hole 1321 has better sealing performance and can avoid water leakage.

[0333] For example, the opening area of the first recess 1311 of the secondary valve is greater than or equal to the opening area of the salt water hole 1323, and the opening area of the third recess 1313 of the secondary valve is greater than or equal to the opening area of the salt suction and water injection hole 1324.

[0334] In the water injection mode, the softening connection hole 1322 and the salt suction and water injection hole 1324 are communicated to form a water injection flow channel 137, so that the soft water at the soft water inlet 119 can be injected into the salt tank 200 through the water injection flow channel 137. At this time, the secondary valve drain hole 1321 is located in the fifth recess 1316 of the secondary valve spool 131 in the orthographic projection of the primary valve spool 121, that is, the secondary valve water inlet 1314 and other recess structures of the secondary valve spool 131 are disconnected with the secondary valve drain hole 1321, and the salt water hole 1323 is located in the first recess 1311 of the secondary valve spool 131 in the orthographic projection of the primary valve spool 121, that is, the secondary valve water inlet 1314 and other recess structures of the secondary valve spool 131 are disconnected with the salt water hole 1323.

[0335] For example, the opening area of the fifth recess 1316 of the secondary valve is greater than the opening area of the secondary valve drain hole 1321.

[0336] In the salt suction mode, the secondary valve water inlet 1314 and the salt water injection hole 1324 are communicated to form a first salt suction flow channel 1341, and the salt water hole 1323 is communicated through the secondary valve first groove 1311 and the softening connection hole 1322 to form a second salt suction flow channel 1342. At this time, the secondary valve blowdown hole 1321 is in the orthographic projection of the secondary valve 131 in the secondary valve second groove 1312, that is, the secondary valve water inlet 1314 and other groove structures of the secondary valve 131 are disconnected with the secondary valve blowdown hole 1321.

[0337] Exemplarily, the opening area of the secondary valve second groove 1312 is greater than or equal to the opening area of the secondary valve blowdown hole 1321.

[0338] In the backwashing mode, the state of the secondary valve core 134 is the same as that in the water production mode, which will not be repeated.

[0339] In the forward washing mode, the salt water injection hole 1324 is in the orthographic projection of the secondary valve 131 in the secondary valve second groove 1312, that is, the secondary valve blowdown hole 1321 and other groove structures of the secondary valve 131 are disconnected with the salt water injection hole 1324, and the salt water hole 1323 is in the orthographic projection of the secondary valve 131 in the secondary valve first groove 1311, that is, the secondary valve water inlet 1314 and other groove structures of the secondary valve 131 are disconnected with the salt water hole 1323.

[0340] Exemplarily, the opening area of the secondary valve second groove 1312 is greater than or equal to the opening area of the salt water injection hole 1324.

[0341] The above describes the structure of the water softening valve, which can be applied to a water softening machine and cooperates with components such as the softening device 190 and the salt tank 200 in the water softening machine to realize softening of raw water and facilitate users to obtain soft water.

[0342] The specific embodiments of the present application will be described below with reference to Figure 1 and Figure 42 .

[0343] The water softening valve comprises:

[0344] The valve housing 110 comprises 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 outlet 118 and the soft water inlet 119 are communicated through the softening device 190, the secondary cavity 112 is communicated with the soft water outlet 114, and the main cavity 111 is communicated with the raw water outlet 118;

[0345] The main valve assembly 120 includes a main valve core 124 and a main driving part 125 for driving the main valve core 124 to move, and the main valve core 124 is located in the main cavity 111, wherein the main cavity 111 and the raw water inlet 113 and the auxiliary cavity 112 and the raw water inlet 113 are connected or disconnected through the main valve core 124;

[0346] The auxiliary valve assembly 130 includes an auxiliary valve core 134 and an auxiliary driving part 135 for driving the auxiliary valve core 134 to move, and the auxiliary valve core 134 is located in the auxiliary cavity 112, and the soft water inlet 119 and the flow passage of the auxiliary valve core 134 are connected or disconnected, and the auxiliary cavity 112 and the flow passage of the auxiliary valve core 134 are connected or disconnected.

[0347] Based on the main driving part 125 driving the main valve core 124 to rotate, the auxiliary driving part 135 drives the auxiliary valve core 134 to rotate, so that the soft water valve is switched between the water making mode, the water filling mode, the salt sucking mode and the cleaning mode.

[0348] It can be understood that the main valve core 124 is switched between the first main valve position and the third main valve position by the main driving part 125 driving the main valve core 124 to rotate, and the auxiliary valve core 134 is switched between the plurality of auxiliary valve positions by the auxiliary driving part 135 driving the auxiliary valve core 134 to rotate, so that the soft water valve is switched between the water making mode, the water filling mode, the salt sucking mode and the cleaning mode.

[0349] When the soft water valve needs to be in the water making mode, the main valve core 124 is driven to be in the first main valve position, at this time the main cavity 111 and the raw water inlet 113 are connected through the main valve core 124, and the auxiliary cavity 112 and the raw water inlet 113 are disconnected, so that the raw water can enter the valve housing 110 from the raw water inlet 113, and then the raw water flows to the main cavity 111 through the main valve core 124, and since the main cavity 111 and the raw water outlet 118 are connected, the raw water in the main cavity 111 flows to the softening device 190 through the raw water outlet 118, and the raw water becomes soft water after being treated by the softening device 190, and then the soft water flows into the valve housing 110 from the soft water inlet 119. At this time, the auxiliary valve core 134 is driven by the auxiliary driving part 135 to be in the first auxiliary valve position, and the soft water inlet 119 is connected with the auxiliary cavity 112 through the auxiliary valve core 134, so that the soft water can flow from the soft water inlet 119 to the auxiliary cavity 112 through the auxiliary valve core 134, and then the soft water flows from the auxiliary cavity 112 to the soft water outlet 114, so that the user can obtain the soft water at the soft water outlet 114, so that the soft water valve realizes the water making function.

[0350] When the soft water valve needs to be in the water filling mode, the main valve core 124 is driven to be in the first main valve position, at this time, the flow path of the raw water is the same as that in the water making mode, the raw water flows along the path of the raw water inlet 113, the main valve core 124, the main cavity 111 and the raw water outlet 118 into the softening device 190. At this time, the auxiliary driving part 135 drives the auxiliary valve core 134 to be in the second auxiliary valve position, the auxiliary valve core 134 communicates the soft water inlet 119 and the auxiliary cavity 112, and the soft water inlet 119 and / or the auxiliary cavity 112 also communicates with the water filling flow channel 137 in the auxiliary valve core 134, so that the soft water can flow into the auxiliary cavity 112, and the soft water can also flow into the salt tank 200 connected with the soft water valve through the water filling flow channel 137, to realize the water filling function of the soft water valve.

[0351] When the soft water valve needs to be in the salt suction mode, the main valve core 124 is driven to be in the third main valve position, at this time, the auxiliary cavity 112 and the raw water inlet 113 are communicated through the main valve core 124, the main valve core 124 disconnects the raw water inlet 113 and the main cavity 111, at this time, the raw water can enter the valve housing 110 from the raw water inlet 113, and then the raw water flows to the auxiliary cavity 112 through the main valve core 124. At this time, the auxiliary valve core 134 is driven to be in the third auxiliary valve position, so that the auxiliary cavity 112 cannot directly communicate with the soft water inlet 119, but needs to communicate with the soft water inlet 119 through the flow channel in the auxiliary valve core 134, so that part of the raw water in the auxiliary cavity 112 flows along the flow channel in the auxiliary valve core 134 to the soft water inlet 119, and in the process of flowing from the flow channel in the auxiliary valve core 134 to the soft water inlet 119, the raw water can be mixed with the brine, and then the mixed liquid is transported to the soft water inlet 119 and enters the softening device 190 from the soft water inlet 119, so that the brine can regenerate the softening device 190. Another part of the raw water in the auxiliary cavity 112 can flow to the soft water outlet 114, so that the user can still use the raw water in the salt suction mode.

[0352] When the cleaning mode includes the backwashing mode, the soft water valve needs to be in the backwashing mode, the main valve core 124 is driven to be in the third main valve position, at this time, the path of the raw water flowing into the auxiliary cavity 112 is the same as that in the salt suction mode, the raw water flows along the raw water inlet 113 and the main valve core 124 into the auxiliary cavity 112. At this time, the auxiliary driving part 135 drives the auxiliary valve core 134 to be in the first auxiliary valve position, so that the auxiliary cavity 112 and the soft water inlet 119 are communicated, part of the raw water in the auxiliary cavity 112 flows to the soft water inlet 119 through the auxiliary valve core 134, and then flows to the softening device 190 through the soft water inlet 119 to clean the softening device 190, the cleaned sewage flows out of the softening device 190 from the raw water outlet 118 and is discharged from the valve housing 110. Another part of the raw water in the auxiliary cavity 112 can flow to the soft water outlet 114, so that the user can still use the raw water in the salt suction mode.

[0353] When the cleaning mode includes the forward washing mode, the drive main valve core 124 is in the first main valve position, and the flow path of the raw water is the same as that in the water production mode. The raw water flows along the path of the raw water inlet 113, the main valve core 124, the main cavity 111, and the raw water outlet 118 into the softening device 190 to clean the softening device 190. At this time, the drive auxiliary valve core 134 is in the fourth auxiliary valve position, and the soft water inlet 119 is communicated with the auxiliary cavity 112 through the auxiliary valve core 134. The water after cleaning the softening device 190 flows out of the softening device 190 from the soft water inlet 119, and then flows into the auxiliary cavity 112 from the soft water inlet. Before controlling the soft water valve to be in the forward washing mode, the soft water valve can be controlled to be in the reverse washing mode first, that is, the reverse washing operation of the soft water valve is performed first to reduce the salt content of the water in the soft water valve. After the reverse washing mode, the salt content of the water in the soft water valve is low in the forward washing mode, and the water can be used by the user, so the water in the auxiliary cavity 112 can be divided into two parts, one part is discharged from the valve housing 110 through the auxiliary valve core 134, and the other part flows to the soft water outlet 114, so that the user can use water in the forward washing mode.

[0354] That is, the soft water valve of the present application can switch between the water production mode, the water injection mode, the salt absorption mode, and the cleaning mode through the cooperation of the valve housing 110, the main cavity 111, the auxiliary cavity 112, the main valve assembly 120, and the auxiliary valve assembly 130, and the user can use water when the soft water valve is in the water production mode, the water injection mode, the salt absorption mode, and the cleaning mode, which meets the 24-hour water demand of the user.

[0355] The embodiment of the second aspect of the present application is described with reference to Figure 43 The soft water machine includes the softening device 190 and the soft water valve of any one of the above embodiments. The inlet of the softening device 190 is communicated with the raw water outlet 118, and the outlet of the softening device 190 is communicated with the soft water inlet 119, so as to realize the water flow regulation and control of the soft water valve and the softening device 190.

[0356] The softening device 190 is located below the valve housing 110 of the soft water valve, and the space layout inside the soft water machine is reasonable. The softening device 190 can be a resin tank, and the resin material in the resin tank can be regenerated as needed to ensure the softening effect.

[0357] The softening connection part 1143 of the water softener valve is provided with a threaded hole. The resin tank communicates with the interior of the water softener valve through the threaded hole. Currently, most resin tank inlets use a 2.5-inch standard threaded hole, so the threaded hole of the water softener valve is matched to it. The threaded part mainly consists of two ports: a central hole, which communicates with the water outlet pipe inside the resin tank. An outlet is provided on the outer periphery of the central hole, which is used to send the raw water in the water softener valve into the resin tank. The resin tank contains resin. The tap water in the resin tank, after being filtered by the resin, flows from the central hole, i.e., the soft water port of the resin tank, into the soft water inlet 119 of the water softener valve, and finally flows out from the soft water outlet 114 of the water softener valve for user use.

[0358] Figure 43 The dotted line with arrows illustrates the flow path of raw water entering the resin tank from above, and then being sent upwards through the outlet pipe of the resin tank to produce soft water.

[0359] The water softener also includes a brine tank 200, which is connected to the water softener valve via a brine tank connection port 1110. The brine tank 200 can be set up side by side with the softening device 190. The position of the brine tank 200 is flexible and can be set as needed.

[0360] The water softener valve is mounted on top of the resin tank, next to which is a brine tank 200. The brine tank connection port 1110 of the water softener valve is connected to the brine tank 200 via a flexible hose. When drawing brine, the brine in the brine tank 200 is drawn into the water softener valve through the ejector 160. When filling the brine tank 200 with water, water from the water softener valve is also injected into the brine tank 200 through the same pipeline.

[0361] By using the water softener valve described in the above embodiments, the softened water flow rate can be increased by replacing the valve without altering the structure and position of components such as the softening device 190 and the brine tank 200 within the water softener. Of course, after replacing the water softener valve, the structure and shape of other components within the water softener can also be adjusted accordingly.

[0362] The water softener has two 1-inch pipe interfaces at the rear of its casing, which are divided into an inlet pipe and an outlet pipe. The inlet pipe is connected to external tap water and is connected to the internal space of the valve housing 110 through the raw water inlet 113, so that the raw water flows into the softening valve. The softened water flowing out of the softening valve is connected to the outlet pipe through the softening outlet 114 for user use.

[0363] The embodiments of this application enable water circuit adjustment for different states of the water softener. The entire valve head has a compact structure and adopts a ceramic plate design, resulting in high reliability and stable operation. The multi-functional water softener valve features a two-chamber design, with a simple and ingenious valve body flow channel structure and a strong overall appearance, which helps to reduce size.

[0364] The above embodiments are only used for illustrating the present application, but not limiting the present application. Although the present application is explained in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present application do not deviate from the spirit and scope of the present application, and should be covered in the scope of claims of the present application.
