Illustratively, the valve housing 110 is constructed with a water outlet flow passage 1112, and the water outlet flow passage 1112 communicates with the sub-chamber communication hole 1111 and the soft water outlet 114, so that water in the sub-chamber 112 can flow along the sub-chamber communication hole 1111, the water outlet flow passage 1112 and the soft water outlet 114.

It should be noted that the water outlet channel 1112 may be directly connected to the soft water outlet 114, and the water outlet channel 1112 may also be connected to the soft water outlet 114 through a corresponding channel.

Wherein the valve housing 110 is constructed with a soft water passage that communicates the sub-chamber 112 and the soft water outlet 114 such that water in the sub-chamber 112 can flow along the soft water passage to the soft water outlet 114.

It will be appreciated that the soft water passage may communicate with the sub-chamber 112 through the outlet flow passage 1112 such that water within the sub-chamber 112 may flow along the outlet flow passage 1112 and the soft water passage to the soft water outlet 114.

Illustratively, the valve housing 110 is connected with a flow meter 150, a detection portion of the flow meter 150 is located in the soft water passage, and the flow meter 150 can detect the flow of water flowing out through the soft water passage.

Wherein the valve housing 110 is constructed with a raw water passage, one end of which is formed with a raw water inlet 113, and the other end of which may be communicated with at least one of the main chamber 111 and the sub-chamber 112, so that raw water may be introduced into at least one of the main chamber 111 and the sub-chamber 112.

It can be appreciated that the main valve assembly 120 is located at the other end of the raw water channel, so that raw water is firstly delivered to the main valve assembly 120, the main valve assembly 120 has at least two flow paths, one flow path is used for communicating the other end of the raw water channel with the main cavity 111, the other flow path is used for communicating the other end of the raw water channel with the auxiliary cavity 112, and the two flow paths are controlled to be on-off by the main valve assembly 120, so that on-off control of the raw water inlet 113 and the main cavity 111 can be realized, and on-off control between the raw water inlet 113 and the auxiliary cavity 112 can also be realized.

Wherein, the valve housing 110 is configured with a communication channel 1113, an outlet of the communication channel 1113 is communicated with the auxiliary cavity 112, and an inlet of the communication channel 1113 can be adjusted to be on-off with the raw water inlet 113, i.e. the inlet of the communication channel 1113 can be communicated with the raw water inlet 113 or disconnected with the raw water inlet 113. When the inlet of the communication passage 1113 communicates with the raw water inlet 113, raw water enters the valve housing 110 through the raw water inlet 113, and then raw water enters the sub-chamber 112 through the communication passage 1113; when the inlet of the communication passage 1113 is disconnected from the raw water inlet 113, it is indicated that the raw water cannot directly flow to the sub-chamber 112 at this time.

Illustratively, the inlet of the communication channel 1113 is opened and closed to the raw water inlet 113 by the main valve assembly 120, and since the main valve assembly 120 is positioned 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 achieved by the main valve assembly 120.

Of course, the outlet of the communication channel 1113 may be connected to the auxiliary chamber 112 (not shown), and the auxiliary valve assembly 130 is connected to the auxiliary chamber 112 and the communication channel 1113, and the communication channel 1113 and the raw water inlet 113 may be normally connected or connected through the main valve assembly 120. The communication channel 1113 may be connected to the main chamber 111 through the main valve assembly 120, and in the case that the main chamber 111 is connected to the raw water inlet 113, the main valve assembly 120 regulates connection and disconnection of the main chamber 111 and the auxiliary chamber 112, that is, the main valve assembly 120 may control both the main chamber 111 and the auxiliary chamber 112 to be connected to the raw water inlet 113, or the main valve assembly 120 enables the raw water inlet 113 to be simultaneously connected to the main chamber 111 and the auxiliary chamber 112.

Referring to fig. 2 and 3, the inlet of the communication channel 1113 is located at the bottom of the main cavity 111, the inlet of the communication channel 1113 corresponds to the main-auxiliary connection hole 1223 of the main static valve plate 122, and water inlet of the communication channel 1113 is mainly controlled by the main valve core 124 located in the main cavity 111. The active valve plate 121 can actively control whether raw water can flow into the auxiliary cavity 112, and the communication channels 1113 of the two cavities are designed to be in a controllable state, so that the user can use water in the regeneration process of the softening material of the water softener, and the regeneration of the softening material cannot be influenced. The outlet of the communication channel 1113 is communicated with the auxiliary cavity 112, the side wall of the auxiliary cavity 112 is provided with an auxiliary communication port 1136, and the outlet of the communication channel 1113 is the auxiliary communication port 1136, so that a channel for connecting the two cavities is formed.

The outlet end of the communication channel 1113 is communicated with the auxiliary communication port of the auxiliary cavity 112, the inlet end of the communication channel 1113 is communicated with the main communication port of the main cavity 111, the main communication port is communicated with the raw water inlet 113 through the main valve core 124, so that the soft water valve can be switched between a state that the raw water inlet 113 is communicated with the main communication port and a state that the raw water inlet 113 is disconnected from the main communication port, namely, the on-off between the raw water inlet 113 and the communication channel 1113 can be controlled through the main valve core 124, and the communication channel 1113 can be communicated with the auxiliary cavity 112 through the auxiliary communication port, so that the main valve core 124 can control the on-off between the raw water inlet 113 and the auxiliary cavity 112.

Wherein, the auxiliary communication port can be connected with the raw water inlet 113 by the auxiliary valve core 134 in an on-off way, so that the soft water valve can be switched between a state that the raw water inlet 113 is communicated with the auxiliary communication port and a state that the raw water inlet 113 is disconnected from the auxiliary communication port, namely, the on-off of the raw water inlet 113 and the auxiliary cavity 112 can be controlled.

The outlet of the communication passage 1113 is formed in the wall surface of the sub-chamber 112, and the outlet of the communication passage 1113 is located on the same side of the sub-chamber communication hole 1111 as the sub-valve element 134. When the communication passage 1113 communicates with the raw water inlet 113, raw water may directly flow to the sub-chamber 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 sub-chamber communication hole 1111 without passing through the sub-valve cartridge 134, simplifying the structure of the sub-valve cartridge 134.

The outlet of the communication channel 1113 and the soft water inlet 119 are respectively located at two sides of the auxiliary valve core 134, so that the auxiliary valve core 134 can control the on-off between the outlet of the communication channel 1113 and the soft water inlet 119, and the auxiliary valve core 134 can play a role in separating the outlet of the communication channel 1113 and the soft water inlet 119.

It should be noted that "two sides" of the "two sides of the sub spool 134" refers to two positions where the sub spool 134 is spaced apart, i.e., "two sides" refers to a relationship including, but not limited to, front-to-back, left-to-right, up-and-down.

When the outlet of the communication passage 1113 is higher than the sub-chamber communication hole 1111, so that raw water flows to the sub-chamber communication hole 1111 through the communication passage 1113, raw water can flow to the soft water outlet 114 through the sub-chamber communication hole 1111, and the problem of water accumulation in the sub-chamber 112 caused by the fact that the outlet of the communication passage 1113 is lower than the sub-chamber communication hole 1111 is avoided.

The sub valve water inlet 1314 is correspondingly communicated with the sub communication port based on the state that the soft water valve is in communication with the raw water inlet 113 of the sub chamber 112. The auxiliary valve water inlet 1314 is communicated with the auxiliary chamber 112, and when raw water flows into the auxiliary chamber 112 through the raw water inlet 113 and the auxiliary communication port, the raw water can directly flow into the auxiliary chamber 112, and the auxiliary movable valve plate can not block the raw water from flowing into the auxiliary chamber 112, so that the raw water can smoothly flow into the auxiliary chamber 112.

Specifically, the main driving part 125 is configured to drive the main spool 124 such that the main spool 124 is switched between a third main valve position that communicates the inlet of the communication passage 1113 with the raw water inlet 113 and a first main valve position that communicates the main chamber 111 with the raw water inlet 113.

It will be appreciated that the main valve 124 is driven by the main driving part 125 to switch between the first main valve position and the third main valve position, when the main valve 124 is at the first main valve position, the main valve 124 communicates with the main chamber 111 and the raw water inlet 113, and simultaneously the main valve 124 blocks the raw water inlet 113 and the inlet of the communication channel 1113, so that raw water flows into the main chamber 111, and 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 spool 124 is in the third main valve position, the main spool 124 communicates with the inlet of the communication passage 1113 and the raw water inlet 113, so that raw water flows into the sub-chamber 112 through the raw water inlet 113 and the communication passage 1113, and at this time, the main spool 124 blocks the raw water inlet 113 and the main chamber 111, and at this time, the soft water valve is in the salt suction mode or the backwash mode.

That is, when the washing mode includes a forward washing mode and a reverse washing mode, in which the water making mode, the water filling mode, and the forward washing mode, the main valve cartridge 124 is at the first main valve position, the communication flow passage 128 is disconnected, the raw water inlet 113 is communicated with the main chamber 111, at this time, the main valve assembly 120 is mainly used to convey raw water to the main chamber 111, so that the raw water enters the softening device 190, and at this time, the sub valve assembly 130 is switched through the flow passage, so that the soft water valve is switched among the water making mode, the water filling mode, and the forward washing mode; in the salt suction mode and the backwash mode, the communication flow passage 128 is communicated, the raw water inlet 113 is disconnected from the main chamber 111, at this time, the main valve assembly 120 is mainly used for delivering the softening device 190 to the sewage discharge valve housing 110 of the raw water outlet 118, and the sub valve assembly 130 at this time is switched to switch the soft water valve between the salt suction mode and the backwash mode by switching the flow passage.

Note that, in the salt suction mode and the backwash mode, the main spool 124 is driven in the third main valve position such that the communication passage 1113 communicates with the raw water inlet 113 and the sub-chamber 112 such that the raw water inlet 113, the communication passage 1113, and the sub-chamber 112 communicate. Raw water can flow to the auxiliary cavity 112 through the raw water inlet 113 and the communication channel 1113, and then the soft water valve is switched between a salt suction mode and a backwashing 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, and the auxiliary cavity 112 is communicated with the soft water outlet 114, so that water at the soft water outlet 114 is raw water in the salt suction mode and the backwashing mode, and the water availability of a user in the salt suction mode and the backwashing mode is ensured.

Wherein, at the third main valve position, the main valve core 124 is driven by the main driving part 125 such that the communication flow passage 128 of the main valve core 124 communicates, and the inlet of the communication passage 1113 communicates with the raw water inlet 113 through the communication flow passage 128 such that the raw water inlet 113, the communication flow passage 128, the communication passage 1113, and the sub-chamber 112 communicate. The inlet of the communication passage 1113 and the raw water inlet 113 are communicated by the communication flow passage 128, so that water can flow along the paths of the raw water inlet 113, the communication flow passage 128, the communication passage 1113, and the sub-chamber 112. The inlet of the communication channel 1113 is connected to the raw water inlet 113 through the communication flow channel 128, and when the main valve member 124 rotates to the first main valve position, the communication flow channel 128 is disconnected, so that the inlet of the communication channel 1113 is disconnected from the raw water inlet 113, and when the main valve member 124 rotates to the third main valve position, the communication flow channel 128 is communicated, so that the inlet of the communication channel 1113 is communicated with the raw water inlet 113.

Illustratively, the inlet of the communication flow channel 128 communicates with the raw water inlet 113, the outlet of the communication flow channel 128 communicates with the inlet of the communication channel 1113, the inlet of the communication flow channel 128 faces the raw water inlet 113, that is, the inlet of the communication flow channel 128 is not communicated with the main cavity 111, raw water flows through paths of the raw water inlet 113, the inlet of the communication flow channel 128, the communication channel 1113 and the auxiliary cavity 112, raw water does not need to pass through the main cavity 111, the main cavity 111 and the raw water inlet 113 can be separated, and it is ensured that raw water cannot enter the main cavity 111 in the third position of the main valve.

Illustratively, the main valve water inlet 1221 of the main static valve plate 122 is communicated with the main and auxiliary connecting holes 1223 of the main static valve plate 122 through the main valve first groove 1212 of the main dynamic valve plate 121 to form a communication flow passage 128, the main and auxiliary connecting holes 1223 are communicated with the inlet of the communication passage 1113, the inlet of the communication flow passage 128 is formed in the main valve water inlet 1221, and the outlet of the communication flow passage 128 is formed in the main and auxiliary connecting holes 1223. The main driving part 125 drives the driving valve plate 121 to rotate to the third main valve position, so that the main valve first groove 1212 communicates with the main valve water inlet 1221 and the main and auxiliary connecting holes 1223, and the main valve water inlet 1221, the main valve first groove 1212 and the main and auxiliary connecting holes 1223 communicate to form a communication flow passage 128, and raw water can flow along the paths of the raw water inlet 113, the main valve water inlet 1221, the main valve first groove 1212, the main and auxiliary connecting holes 1223, the communication passage 1113 and the auxiliary cavity 112.

Wherein, in the salt suction mode and the backwashing mode, the main valve water inlet 1221 comprises a first area and a second area which are communicated, the first area is communicated with the main and auxiliary connecting holes 1223 through the main valve first groove 1212, and the second area is closed through the main valve process groove of the main valve plate 121. So that raw water flows to the sub-chamber through the first region, the main valve first groove 1212, and the main and sub-connection hole 1223.

Wherein, the main valve water inlet 1221 can be normally communicated with the raw water inlet 113, and the main driving part 125 drives the driving valve plate 121 to rotate to realize on-off control of the communicating flow channel 128, so that the structure of the main valve assembly 120 can be simplified.

Referring to fig. 7, 8, 36 and 40, the main valve assembly 120 includes a main valve body 124 and a main driving part 125 for driving the main valve body 124 to move, the main valve body 124 is positioned in the main valve body 111, and the main valve body 111 and the raw water inlet 113 are on-off adjustable through the main valve body 124, so that the main valve body 111 and the raw water inlet 113 can be switched between on-off.

In still other cases, the connection between the auxiliary chamber 112 and the raw water inlet 113 is adjustable by the main valve core 124, so that the connection between the auxiliary chamber 112 and the raw water inlet 113 can be switched between connection and disconnection. When the sub-chamber 112 communicates with the raw water inlet 113, raw water enters the sub-chamber 112 and then the flow direction of the water is distributed through the sub-valve assembly 130. When the sub-chamber 112 is disconnected from the raw water inlet 113, raw water flows into the main chamber 111 through the main valve body 124, then water flows to the soft water inlet 119 through the raw water outlet 118, and then the flow direction of the water is controlled by the sub-valve assembly 130 and the sub-chamber 112 in cooperation.

The auxiliary valve assembly 130 comprises an auxiliary valve core 134 and an auxiliary driving part 135 for driving the auxiliary valve core 134 to move, the auxiliary valve core 134 is positioned in the auxiliary cavity 112, the on-off of a runner of the auxiliary valve core 134 is regulated, the on-off of a soft water inlet 119 and a corresponding channel in the auxiliary valve core 134 can be regulated, and the on-off of the auxiliary cavity 112 and a corresponding channel in the auxiliary valve core 134 can also be regulated, for example, the auxiliary valve core 134 can regulate the on-off of the soft water inlet 119 and the auxiliary cavity 112, the on-off of a salt box connection opening 1110 of the auxiliary cavity 112 and the valve housing 110, the on-off of the soft water inlet 119 and the ejector 160 of a soft water valve, and the like, the auxiliary cavity 112 and the auxiliary valve assembly 130 are mainly used for realizing the regeneration of softening materials in the softening device 190 (a regeneration process comprises a water injection mode, a salt absorption mode and a cleaning mode), and the auxiliary valve assembly 130 is also used for continuously supplying water to the soft water outlet 114.

The sub-driving part 135 may drive the sub-valve body 134 to move based on the movement of the main valve body 124 driven by the main driving part 125, so that the soft water valve is switched between the water making mode, the water filling mode, the salt absorbing mode, and the washing mode.

The main chamber 111 and the main valve assembly 120 are matched to mainly supply water to the softening device 190, the main chamber 111 and the main valve assembly 120 mainly have the functions of normally producing water, and the main chamber 111 and the main valve core 124 are used for producing water due to the large flow rate of the normally produced water, and the auxiliary valve core 134 is used for communicating the soft water inlet 119 with the auxiliary chamber 112. The secondary chamber 112 and the secondary valve assembly 130 cooperate primarily to deliver soft water from the softener 190 to the secondary chamber 112 for each mode requiring soft water, the large open cell structure of the secondary chamber 112 and the secondary spool 134 for water intake by the user. Since the water softener has functions of other states, such as forward washing, reverse washing, water injection, salt suction and slow washing, etc., which are relatively small in flow rate, the open area of the holes for water injection and salt suction in the sub-valve cartridge 134 may be smaller than that of the holes for water intake, and thus the states are mainly controlled by the sub-chamber 112 and the sub-valve assembly 130, and the main chamber 111 and the main valve assembly 120 serve an auxiliary function. The auxiliary chamber 112 and the auxiliary valve assembly 130 are mainly used for regulating other flow paths, the main chamber 111 and the main valve assembly 120 cooperate to increase the flow rate of water sent to the softening device 190, and the auxiliary chamber 112 and the main chamber 111 cooperate to perform other functions.

The main chamber 111 and the main valve assembly 120 are matched to perform normal water production, and the main valve core 124 forms a main water production flow channel 126 due to the relatively large raw water flow requirement in the water production mode, the main water production flow channel 126 is communicated with the main chamber 111 and the raw water inlet 113, and the main chamber 111 and the raw water outlet 118 are communicated, so that water production is performed by utilizing the large open pore structure of the main valve core 124. In the water making mode, the sub-spool 134 forms a sub-water making flow passage 136, the soft water inlet 119 communicates with the sub-chamber 112 through the sub-water making flow passage 136, the soft water outlet 114 communicates with the sub-chamber 112, and water intake is performed using the large open-cell structure of the sub-spool 134.

Because the water softener has functions of other states, such as cleaning, water injection, salt absorption and slow washing, the flow requirement of raw water is smaller, a plurality of flow passages can be formed by the auxiliary valve core 134, the flow passage formed by the auxiliary valve core 134 needs smaller flow area, the states are mainly controlled by the auxiliary cavity 112 and the auxiliary valve assembly 130, and the main cavity 111 and the main valve assembly 120 are matched with the regeneration processes to carry out pollution discharge. In some cases, the primary chamber 111 is the same shape as the secondary chamber 112, the primary valve assembly 120 is the same size as the outer profile of the secondary valve assembly 130, and the flow area of the flow passage formed by the secondary chamber 112 and the secondary valve assembly 130 is less than the flow area of the primary water flow passage 126 formed by the primary chamber 111 and the primary valve assembly 120.

At least one of the main chamber 111 and the sub chamber 112 may be in communication with the raw water inlet 113 as described above, it is understood that at least one of the main chamber 111 and the sub chamber 112 is introduced with raw water, raw water is fed into the softening device 190 through at least one of the main chamber 111 and the sub chamber 112, wherein at least one of the main chamber 111 and the sub chamber 112 may be in communication with the raw water inlet 113 through a passage, that is, a passage may be provided between the main chamber 111 and the raw water inlet 113, and/or a passage may be provided between the sub chamber 112 and the raw water inlet 113; of course, in the case where both the main chamber 111 and the sub chamber 112 are communicated with the raw water inlet 113, the main chamber 111 and the sub chamber 112 may be communicated with the raw water inlet 113 through separate passages, or one of the main chamber 111 and the sub chamber 112 may be communicated with the raw water inlet 113 through a passage, and the main chamber 111 and the sub chamber 112 may be communicated through a communication passage 1113.

The soft water valve provided by the embodiment of the utility model has the advantages that the multifunctional two-cavity structural design can meet the use requirements of different states of the water softener, the waterway adjustment of different states of the water softener, namely the waterway function requirements of a plurality of states such as a water making mode, a cleaning mode (comprising at least one of forward washing and backwashing), a water injection mode, a salt absorption slow washing mode (hereinafter called a salt absorption mode) and the like are realized through waterway switching of the main valve assembly 120 and the auxiliary valve assembly 130, and the whole valve head has a compact and simple structure, higher reliability and good working stability.

The valve housing 110 is formed with a drain 1114, and the drain 1114 may communicate with at least one of the main chamber 111 and the sub-chamber 112 to realize drain of different flow paths. Illustratively, one end of the trapway 1114 communicates with at least one of the main chamber 111 and the auxiliary chamber 112, and the other end of the trapway 1114 forms the trapway 115 such that the sewage within the valve housing 110 can be discharged through the trapway 1114 and the trapway 115.

In some cases, referring to fig. 7 and 8, at least one of the main valve assembly 120 and the auxiliary valve assembly 130 is a multi-position and multi-way valve, and the main valve assembly 120 and the auxiliary valve assembly 130 can be switched at a plurality of positions, so that on-off adjustment of various flow paths can be realized after the switching.

For example, the main valve assembly 120 may be switched between at least two main valve positions, one main valve position in which the main valve assembly 120 communicates the main chamber 111 with the raw water inlet 113 for supplying water to the softening device 190, and the soft water valve at this time corresponds to the water making mode and the water filling mode; in the other main valve position, the main valve assembly 120 is communicated with the raw water outlet 118 and the sewage outlet 115 to realize sewage discharge, and the soft water valve is correspondingly arranged in a backwashing mode and a salt absorbing mode; in another main valve position, the main valve assembly 120 may also communicate the secondary chamber 112 with the raw water inlet 113; the secondary valve assembly 130 may be switched between a plurality of secondary valve positions (e.g., three, four, five, etc.), one for each mode of soft water valve. The secondary valve assembly 130 may also be switched between three secondary valve positions (not shown), primarily for cleaning and cooperating water and salt suction modes. The main valve assembly 120 and the sub-valve assembly 130 have various structures, and functions and structures of the main valve assembly 120 and the sub-valve assembly 130 can be set as required.

In some cases, referring to fig. 7, 8 and 40, the main drive portion 125 of the main valve assembly 120 is used to drive the main spool 124 in rotation, the main spool 124 being switched between a plurality of main valve positions by rotation. And/or, the secondary drive portion 135 of the secondary valve assembly 130 is configured to drive the secondary spool 134 to rotate, the secondary spool 134 being switched between a plurality of secondary valve positions by rotation.

At least one of the main valve assembly 120 and the auxiliary valve assembly 130 is a disc valve, the disc valve has a simple structure, and the valve plates of the main valve core 124 and the auxiliary valve core 134 can be ceramic plates.

When the valve plate of the butterfly valve is a ceramic plate, the service life and reliability of the butterfly valve are high due to the fact that the ceramic plate is good in wear resistance. Compared with the situation that the plunger valve is higher in structural machining precision, the manufacturing cost of the disc valve is reduced, and the disc valve is an important direction of soft water valve development.

Referring to fig. 9 to 14 and 16 to 18, it can be understood that in the water making mode, the main water making flow passage 126 of the main spool 124 communicates, the main water making flow passage 126 communicates with the main chamber 111 and the raw water inlet 113, the sub chamber 112 communicates with the soft water inlet 119, and the raw water inlet 113, the main water making flow passage 126, the main chamber 111, the raw water outlet 118, the soft water inlet 119, the sub chamber 112 and the soft water outlet 114 communicate. The main chamber 111 and the main valve assembly 120 are mainly used for supplying water to the softening device 190 in the water making mode, so that the flow rate of the soft water valve for supplying water to the softening device 190 is increased, and the flow rate of soft water produced by the softening device 190 is increased, so that a user can take the soft water conveniently.

In the water making mode, the main chamber 111 is matched with the main chamber assembly 120 so that the raw water inlet 113 is communicated with the main chamber 111, the auxiliary chamber 112 is matched with the auxiliary valve assembly 130 so that the auxiliary chamber 112 is communicated with the soft water outlet 114, and the raw water outlet 118, the soft water inlet 119, the auxiliary chamber 112 and the soft water outlet 114 are communicated based on the raw water inlet 113, the main water making flow channel 126, the main chamber 111, the raw water outlet 118, the soft water inlet 119, the auxiliary chamber 112 and the soft water outlet 114, so that water can flow along a path communicated with the raw water inlet 113, the main chamber 111, the raw water outlet 118, the soft water inlet 119, the auxiliary chamber 112 and the soft water outlet 114, the water is supplied to the softening device 190 through the main chamber assembly 120 and the main chamber 111, soft water obtained after softening by the softening device 190 can be discharged to the auxiliary chamber 112 through the soft water inlet 119, soft water in the auxiliary chamber 112 is discharged through the soft water outlet 114, and the auxiliary valve assembly 130 is used for communicating the soft water inlet 119 and the auxiliary chamber 112 so that the soft water can be discharged from the soft water inlet 119 to the auxiliary chamber 112, the soft water outlet 114 is ensured, and water taking is convenient for a user.

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 the main water making channel 126 for communication. It can be understood that: the main water flow channel 126 may be connected in some modes and disconnected in some modes.

Referring to fig. 9, the main valve core 124 includes a main static valve plate 122 and a main valve plate 121, the main valve plate 121 is connected to the main driving portion 125, the main static valve plate 122 is fixed to the valve housing 110, the main static valve plate 122 is configured with a main valve water inlet 1221, the main valve plate 121 is configured with a main valve water inlet 1211, the main valve water inlet 1221 is communicated with the raw water inlet 113, the main valve water inlet 1211 is communicated with the main cavity 111, and the main valve water inlet 1221 is communicated with the main valve water inlet 1211 to form a main water making flow channel 126. The main driving part 125 drives the driving valve plate 121 to adjust the position relative to the main static valve plate 122, so that the on-off adjustment of the main cavity 111 and the raw water inlet 113 is realized, and the device has a simple structure and is convenient to adjust.

It will be appreciated that in the water making mode, the main driving part 125 drives the driving valve plate 121 to move such that the main valve water inlet 1211 and the main valve water inlet 1221 are correspondingly communicated, that is, the main water making channel 126 formed by the main valve water inlet 1211 and the main valve water inlet 1221 is communicated, and the water at the raw water inlet 113 can flow to the main chamber 111 through the main water making channel 126. In the partial non-water making mode, the main driving part 125 drives the driving valve plate 121 to move so that the main valve water inlet 1211 and the main valve water inlet 1221 are not correspondingly connected, i.e., the main valve water inlet 1211 and the main valve water inlet 1221 are disconnected, the main water making flow passage 126 is disconnected, the raw water inlet 113 cannot be connected with the main chamber 111, and water at the raw water inlet 113 cannot flow to the main chamber 111.

It will be appreciated that when the soft water valve is switched from the other mode to the water making mode, the main driving part 125 drives the driving valve plate 121 to rotate to the first main valve position, and the main valve water inlet 1211 and the main valve water inlet 1221 at this time are communicated to form the main water making flow path 126, so that the raw water inlet 113 can be communicated with the main chamber 111 through the main water making flow path 126, and water can be injected into the resin tank through the main water making flow path 126.

When the main driving portion 125 is used for driving the driving valve plate 121 to rotate, the driving valve plate 121 can rotate to connect or disconnect the main valve water inlet 1211 and the main valve water inlet 1221. The main valve water inlet 1221 may be a fan-shaped hole, and the main valve water inlet 1211 may be formed by a fan-shaped gap of the driving valve plate 121 to ensure a flow area of raw water.

In the above, the main valve assembly 120, the main chamber 111, and the valve housing 110 are described in the water making mode.

The water making mode is a main function mode of the soft water valve, and other function modes (water injection mode, salt suction mode and cleaning mode) of the soft water valve are mainly used for ensuring the softening effect of the softening device 190 and regenerating the softening material in the softening device 190 so as to continuously provide soft water. The water injection mode mainly injects water into the salt tank 200 to melt salt in the salt tank 200 and regenerate the softened material in the softening device 190.

Next, the sub valve assembly 130, the sub chamber 112, and the valve housing 110 in the water making mode will be described.

In the water making mode, the secondary water making flow passage 136 of the secondary spool 134 communicates, and the secondary water making flow passage 136 communicates with the soft water inlet 119 and the secondary chamber 112 such that the raw water inlet 113, the main water making flow passage 126, the main chamber 111, the raw water outlet 118, the soft water inlet 119, the secondary water making flow passage 136, the secondary chamber 112 and the soft water outlet 114 communicate. It will be appreciated that in the water making mode, the sub spool 134 is driven by the sub driving part 135, so that the sub spool 134 communicates with the soft water inlet 119 and the sub chamber 112. Specifically, in the water making mode, the secondary water making flow path 136 of the secondary valve element 134 is communicated, the secondary water making flow path 136 is mainly used for communicating the soft water inlet 119 with the secondary chamber 112, and based on the state of the main valve assembly 120 in the water making mode, the raw water inlet 113, the main water making flow path 126, the main chamber 111, the raw water outlet 118 and the soft water inlet 119 are communicated, that is, raw water can be delivered 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 delivered from the soft water inlet 119 to the valve housing 110. At this time, the soft water inlet 119 is communicated with the auxiliary cavity 112 through the auxiliary water making flow passage 136, and then the soft water inlet 119, the auxiliary water making flow passage 136, the auxiliary cavity 112 and the soft water outlet 114 are communicated, and soft water at the soft water inlet 119 can flow along the paths of the auxiliary water making flow passage 136, the auxiliary cavity 112 and the soft water outlet 114, so that a user can obtain soft water at the soft water outlet 114, and the water making function of the soft water valve is realized.

It will be appreciated that the secondary drive portion 135 drives the secondary spool 134 such that the secondary spool 134 is in the first secondary valve position, at which time the secondary spool 134 may communicate the secondary chamber 112 with the soft water inlet 119 such that water at the soft water inlet 119 may flow into the secondary chamber 112.

It will be appreciated that when the secondary spool 134 is in the first secondary valve position, the secondary water making flow passage 136 of the secondary spool 134 communicates, and the soft water inlet 119 communicates with the secondary chamber 112 through the secondary water making flow passage 136.

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, the auxiliary static valve plate 132 is fixed to the valve housing 110, the auxiliary static valve plate 132 is configured with a softening connection hole 1322, the auxiliary dynamic valve plate 131 is configured with an auxiliary valve water inlet 1314, the softening connection hole 1322 is communicated with the soft water inlet 119, the auxiliary valve water inlet 1314 is communicated with the auxiliary cavity 112, and the softening connection hole 1322 is communicated with the auxiliary valve water inlet 1314 to form an auxiliary water making flow channel 136.

It can be appreciated that in the water making mode, the auxiliary driving portion 135 drives the auxiliary moving valve plate 131 to rotate, so that the relative position between the auxiliary moving valve plate 131 and the auxiliary static valve plate 132 is changed, the auxiliary valve water inlet 1314 and the softening connecting hole 1322 are communicated to form the auxiliary water making flow passage 136, and at this time, the soft water inlet 119 can be communicated with the auxiliary cavity 112 through the auxiliary water making flow passage 136, so that water at the soft water inlet 119 can flow into the auxiliary cavity 112. In a part of non-water making mode, for example, a salt absorbing mode, the auxiliary driving part 135 drives the auxiliary movable valve plate 131 to rotate, so that the auxiliary movable valve plate 131 rotates relative to the auxiliary static valve plate 132, the auxiliary valve water inlet 1314 and the softening connecting hole 1322 are not communicated, that is, the auxiliary water making flow passage 136 is disconnected at this time, and the soft water inlet 119 cannot be communicated with the auxiliary cavity 112 through the auxiliary water making flow passage 136, so that the soft water valve can operate in other modes.

It will be appreciated that in the water making mode, the auxiliary driving part 135 drives the auxiliary moving valve plate 131 to move to the first auxiliary valve position, so that the auxiliary moving valve plate 131 and the auxiliary static valve plate 132 may form a communicating auxiliary water making flow passage 136, and the soft water inlet 119 and the auxiliary chamber 112 may communicate through the auxiliary water making flow passage 136.

In still other cases, the auxiliary chamber 112 and the soft water inlet 119 may be normally open, and the auxiliary valve element 134 may not be regulated (not shown) to simplify the structure of the auxiliary valve element 134. Regarding the water injection mode:

As can be understood with reference to fig. 9 to 14, 19 to 21, and 36 to 39, 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 passage 137 of the sub-spool 134 communicates the soft water inlet 119 with the salt tank connection port 1110 such that the soft water inlet 119, the water injection flow passage 137, and the salt tank connection port 1110 communicate. By adjusting the state of the sub-valve assembly 130 such that the softening device 190 communicates with the salt tank 200, soft water softened by the softening device 190 is transferred into the salt tank 200 such that salt in the salt tank 200 is dissolved so as to pass the salt solution into the softening device 190.

Specifically, in the water injection mode, the auxiliary driving part 135 drives the auxiliary valve core 134 to rotate to the second auxiliary valve position, the water injection flow passage 137 of the auxiliary valve core 134 enables the salt water injection hole 1324 to be communicated with the salt tank connection port 1110, the salt water injection hole 1324 can be communicated with the soft water inlet 119 or the auxiliary cavity 112, water at the salt water injection hole 1324 can be directly or indirectly conveyed to the salt tank connection port 1110, and then conveyed into the salt tank 200 from the salt tank connection port 1110, so that water injection operation of the salt tank 200 is realized.

Note that the manner in which water flows from the soft water inlet 119 to the salt tank connection port 1110: when the states of the main chamber 111 and the main valve assembly 120 may be the same as the water making mode, raw water may flow along paths of the raw water inlet 113, the main water making flow passage 126, the main chamber 111, the raw water outlet 118 and the soft water inlet 119, so that the raw water is converted into soft water through the softening device 190 and then transferred to the soft water outlet 114, and the soft water is transferred from the soft water outlet 114 to the salt tank connection port 1110 again, thereby realizing the operation of injecting the soft water into the salt tank 200.

The manner in which water flows from the secondary chamber 112 to the salt box connection port 1110: when the flow passage through the main valve assembly 120 is switched, the raw water inlet 113 is communicated with the auxiliary cavity 112, namely, the water at the raw water inlet 113 can be directly conveyed into the auxiliary cavity 112, and the auxiliary cavity 112 is communicated with the salt tank connection port 1110 through the auxiliary valve core 134, so that the raw water injection operation to the salt tank 200 is realized.

It should be noted that the water at the soft water inlet 119 may directly flow to the water injection flow passage 137, i.e., the soft water inlet 119 directly communicates with the water injection flow passage 137; the water at the soft water inlet 119 may also flow to the water injection flow passage 137 after passing through the sub-chamber 112, i.e., the soft water inlet 119, the sub-chamber 112 and the water injection flow passage 137 communicate.

That is, the soft water inlet 119 is communicated with the water injection flow channel 137 through the auxiliary cavity 112, so that the soft water inlet 119, the auxiliary cavity 112 and the water injection flow channel 137 are communicated, water at the soft water inlet 119 can flow to the water injection flow channel 137 after passing through the auxiliary cavity 112, and water at the soft water inlet 119 can also flow to the water injection flow channel 137 partially, and the other part flows into the auxiliary cavity 112. That is, it is ensured that water flows into the sub-chamber 112 during the water filling mode, water in the sub-chamber 112 flows out of the soft water outlet 114, and it is ensured that water is still available to the user during the water filling mode, and the water flowing into the sub-chamber 112 at this time is soft water treated by the softening device 190, i.e., soft water is still available to the user during the water filling mode.

It will be appreciated that in the water injection mode, the manner in which the raw water inlet 113 supplies water to the softening device 190 may be the same as that in the water making mode described above, that is, the raw water inlet 113 and the raw water outlet 118 may be cooperatively communicated with the main valve assembly 120 through the main chamber 111, so that raw water flows into the softening device 190 along the paths of the raw water inlet 113, the main water making flow passage 126, the main chamber 111 and the raw water outlet 118, which helps to simplify the structures of the main chamber 111 and the main valve assembly 120.

In the case where the main valve 124 is provided with the main water flow channel 126, the main water flow channel 126 communicates the main chamber 111 with the raw water inlet 113, and the description of the water making mode can be specifically referred to above, and reference is made to fig. 20, which is not repeated here. It will be appreciated that the water injection mode is different from the water production mode in that the state of the sub valve assembly 130 is different. The soft water valve is switched between the water filling mode and the water producing mode, the main valve core 124 is positioned at the first main valve position, and the two modes can be switched by switching the position of the auxiliary valve core 134. In the water making mode, the position of the auxiliary valve core 134 can be understood as a first auxiliary valve position, in the water filling mode, the position of the auxiliary valve core 134 can be understood as a second auxiliary valve position, the auxiliary valve core 134 is driven to rotate by the auxiliary driving part 135, so that the auxiliary valve core 134 is switched between the first auxiliary valve position and the second auxiliary valve position, that is, the auxiliary driving part 135 is used for driving the auxiliary valve core 134 to rotate to be connected or disconnected to the water filling flow passage 137, the auxiliary water making flow passage 136 is also connected or disconnected, and the auxiliary valve assembly 130 is simple in structure and convenient to operate.

The auxiliary static valve plate 132 is matched with the auxiliary dynamic valve plate 131, can be communicated with the softening device 190 and the salt box 200, and can smoothly send soft water in the softening device 190 into the salt box 200, and has a simple structure.

Specifically, in the water injection mode, the auxiliary driving part 135 drives the auxiliary movable valve plate 131 to rotate to the second auxiliary valve position, so that the relative position of the auxiliary movable valve plate 131 and the auxiliary static valve plate 132 changes, the softening connecting hole 1322 is communicated with the salt-absorbing water injection hole 1324 to form the water injection flow channel 137, the soft water inlet 119 is communicated with the salt tank connecting port 1110 through the water injection flow channel 137, and water at the soft water inlet 119 can be conveyed to the salt tank connecting port 1110 through the water injection flow channel 137. In the partial non-water injection mode, the auxiliary driving part 135 drives the auxiliary movable valve plate 131 to rotate, so that the salt suction water injection hole 1324 and the softening connecting hole 1322 are not communicated any more, the soft water inlet 119 cannot be communicated with the salt tank connecting port 1110 through the water injection flow channel 137, and water at the soft water inlet 119 cannot flow to the salt tank connecting port 1110, so that the soft water valve can operate in different modes.

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 portion 135, the auxiliary static valve plate 132 is fixed to the valve housing 110, the auxiliary static valve plate 132 is configured with a softening connection hole 1322 and a salt-absorbing water injection hole 1324, the softening connection hole 1322 is communicated with the soft water inlet 119, the salt-absorbing water injection hole 1324 is communicated with the auxiliary cavity 112 and the salt tank connection port 1110, the auxiliary dynamic valve plate 131 is configured with an auxiliary valve water inlet 1314, the auxiliary valve water inlet 1314 is communicated with the auxiliary cavity 112, and the softening connection hole 1322 is communicated with the salt-absorbing water injection hole 1324 through the auxiliary valve water inlet 1314 to form the water injection flow channel 137.

It can be understood that the auxiliary driving part 135 drives the auxiliary movable valve plate 131 to rotate, so that the softening connecting hole 1322 and the salt absorbing water injecting hole 1324 are communicated with each other through the auxiliary valve water inlet 1314 to form the water injecting channel 137, and the water injecting channel 137 at this time can be communicated with the soft water inlet 119 and the salt tank connecting port 1110, and also can be communicated with the soft water inlet 119 and the auxiliary cavity 112, so that the soft water at the soft water inlet 119 can flow to the salt tank connecting port 1110, and also can flow to the soft water outlet 114 after passing through the auxiliary cavity 112.

Wherein, when the soft water valve comprises the ejector 160, the salt suction water injection hole 1324 is communicated with the salt box connecting port 1110 through the ejector 160, that is, the water injection flow passage 137 is communicated with the salt box connecting port 1110 through the ejector 160; by switching the state of the sub-spool 134, the soft water valve may also suck the saline solution from the saline tank 200 through the ejector 160 and feed the same into the softening device 190, that is, in the water injection mode and the saline suction mode, the flow paths of water between the softening device 190, the ejector 160 and the saline tank 200 are different; in the water filling mode, water flows along the softening device 190 through the auxiliary valve assembly 130 to the ejector 160 or along from the auxiliary chamber 112 to the ejector 160 and then flows through the ejector 160 into the salt tank connection port 1110; in the salt absorption mode, raw water entering the ejector 160 in the auxiliary cavity 112 drives salt solution in the salt tank 200 to enter the ejector 160, and then mixed solution in the ejector 160 is sent into the softening device 190 through the auxiliary valve assembly 130; in the water injection mode and the salt absorption mode, the flow passage communicating with the interior of the sub valve assembly 130 is different. Of course, in the water injection mode, water flowing into the salt tank connection port 1110 through the water injection flow passage 137 of the sub valve assembly 130 may directly flow into the salt tank connection port 1110 without passing through the ejector 160, and at this time, the salt suction water injection hole 1324 may directly communicate with the salt tank connection port 1110.

In the above-described embodiment, in the water injection mode, the path of the raw water inlet 113 to the sub-valve assembly 130 is the same as that of the water making mode, that is, the soft water is supplied to the salt tank connection port 1110 by the soft water valve control softening device 190, but the water injection mode may introduce the raw water into the salt tank connection port 1110 in other ways. In some cases, in the water injection mode, the main chamber 111 may not be operated, and by adjusting the state of the sub valve assembly 130, in case that the raw water inlet 113 communicates with the sub chamber 112, the sub valve assembly 130 is adjusted so that the sub chamber 112 communicates with the salt tank connection port 1110, or the soft water outlet 114 communicates with the salt tank connection port 1110 by other means, raw water is introduced into the salt tank 200 (not illustrated) through the salt tank connection port 1110, so that salt in the salt tank 200 is dissolved so that the salt water is introduced into the softening device 190. For example, the auxiliary chamber 112 of the valve housing 110 is communicated with the raw water inlet 113, the water injection flow channel 137 is communicated with the auxiliary chamber 112 and the salt tank connection port 1110, raw water in the auxiliary chamber 112 can be fed into the salt tank 200, and salt water can be dissolved in the salt tank 200, at this time, the auxiliary valve water inlet 1314 of the auxiliary movable valve plate 131 is communicated with the salt suction water injection hole 1324, raw water in the auxiliary chamber 112 flows along the directions of the auxiliary valve water inlet 1314, the salt suction water injection hole 1324 and the salt tank connection port 1110, and at this time, the main valve assembly 120 can disconnect or communicate the main chamber 111 with the raw water inlet 113.

The above description has been made of the water injection mode, and after the water injection in the salt tank 200 is completed, the salt in the salt tank 200 is dissolved for a preset period of time, which may be generally 1 hour, 2 hours, etc., and this process may be understood as that the salt tank 200 enters a molten salt state, and in the process of proceeding in the molten salt state, the water making mode may be performed so that the user may take soft water from the soft water outlet 114. After the dissolution of the salt in the salt tank 200 is completed, the salt water is fed into the softening device 190, that is, the salt sucking mode is performed, which will be described below.

Salt absorption mode:

Referring to fig. 9 to 14, 22 to 34, and 36 to 39, it can be understood that the valve housing 110 is connected with the ejector 160, the valve housing 110 is provided with a 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 ejector 160, and the salt solution is fed into the softening device 190 through the cooperation of the ejector 160 and the sub valve assembly 130, and then the sewage after the regeneration of the softened material in the softening device 190 is discharged.

In the salt absorbing mode, as shown in fig. 22 to 24 and 36 to 39, the valve housing 110 is connected with the ejector 160, the ejector 160 is provided with a jet flow passage, the valve housing 110 is provided with a salt tank connection port 1110, in the salt absorbing mode, the jet inlet 161 of the jet flow passage is communicated with the raw water inlet 113 through the auxiliary valve core 134, the suction inlet 163 of the jet flow passage is communicated with the salt tank connection port 1110, and the jet outlet 162 of the jet flow passage is communicated with the soft water inlet 119 through the auxiliary valve core 134. The soft water inlet 119 is communicated with the softening device 190, the raw water inlet 113, the jet inlet 161, the jet outlet 162 and the soft water inlet 119 are communicated, so that raw water of the raw water inlet 113 can flow into the jet flow passage, the raw water and salt water of the salt box connection port 1110 are mixed in the jet flow passage to obtain mixed liquid, and the mixed liquid is introduced into the softening device 190 along the jet outlet 162 and the soft water inlet 119. Wherein, the suction inlet 163 is located on the flow path between the jet inlet 161 and the jet outlet 162, raw water flows along the jet inlet 161 to the jet outlet 162, raw water flows in the jet flow channel, so that negative pressure is generated at the suction inlet 163, under the action of the negative pressure, salt solution in the salt tank 200 is sucked into the jet inlet 161 and the jet flow channel along the salt tank connection port 1110 and the suction inlet 163, so that the salt solution and the raw water are mixed in the jet flow channel to obtain mixed solution, and the mixed solution flows to the softening device 190 along the jet outlet 162, and the process of delivering the mixed solution into the softening device 190 is completed.

It will be appreciated that in the salt absorbing mode, the sub spool 134 is positioned at the third sub valve position by the driving of the sub driving part 135 such that the jet inlet 161 of the jet flow path communicates with the raw water inlet 113, the jet outlet 162 of the jet flow path communicates with the soft water inlet 119, and raw water may flow along the paths of the raw water inlet 113, the jet inlet 161, the jet outlet 162, and the soft water inlet 119.

In some cases, the jet inlet 161 communicates with the sub chamber 112 through the sub spool 134, and the sub chamber 112 communicates with the raw water inlet 113, such that the jet inlet 161 communicates with the raw water inlet 113. Raw water flows from the raw water inlet 113 to the auxiliary cavity 112, and then flows from the auxiliary cavity 112 into the jet flow channel through the jet inlet 161, so that the communication between the jet inlet 161 and the raw water inlet 113 is realized. Of course, the jet inlet 161 may also communicate with the raw water inlet 113 in other ways, such as the jet inlet 161 communicating directly with the raw water inlet 113, or communicating with the raw water inlet 113 through other valve assemblies, without passing through the sub-valve assembly 130.

It will be appreciated that when the jet inlet 161 communicates with the raw water inlet 113 through the sub-chamber 112, raw water may first flow into the sub-chamber 112, a portion of raw water in the sub-chamber 112 may flow into the jet flow path, and another portion of raw water in the sub-chamber 112 may be discharged from the soft water outlet 114, so that water may still be available to the user 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, namely, the soft water inlet 119 is not communicated with the auxiliary cavity 112, and the salt water at the soft water inlet 119 cannot flow into the auxiliary cavity 112, so that the water in the auxiliary cavity 112 is the raw water instead of the salt water, and the raw water is available when a soft water valve is in a salt absorbing mode.

In some cases, the secondary drive portion 135 drives the secondary moving valve plate 131 to rotate such that the secondary valve water inlet 1314 is offset from the softening connection hole 1322, and the secondary moving valve plate 131 blocks the softening connection hole 1322 and the secondary chamber 112. In the salt absorbing mode, the auxiliary valve water inlet 1314 is staggered from the softening connecting hole 1322, namely, 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, the soft water inlet 119 and the auxiliary cavity 112 are blocked, and the brine at the soft water inlet 119 can be prevented from polluting the water at the auxiliary cavity 112.

The first drain runner 127 of the main valve 124 communicates the raw water outlet 118 with the drain outlet 115 of the valve housing 110, so that the raw water of the raw water inlet 113 and the brine of the salt tank connection port 1110 are mixed in the jet runner to obtain mixed liquid, and the mixed liquid flows out along the jet runner, the soft water inlet 119, the raw water outlet 118, the first drain runner 127 and the drain outlet 115. The mixed liquid obtained by mixing the raw water and the brine flows into the softener 190 along the jet outlet 162 and the soft water inlet 119, the mixed liquid regenerates the softener 190 and is discharged from the raw water outlet 118, and the raw water outlet 118 is communicated with the drain outlet 115 of the valve housing 110 through the first drain flow passage 127, so that the mixed liquid flows along the raw water outlet 118, the first drain flow passage 127 and the drain outlet 115 and is discharged out of the valve housing 110.

In some cases, raw water outlet 118 communicates with first drain flow channel 127, for example, through main chamber 111, i.e., the mixed liquid will flow along raw water outlet 118, main chamber 111, and first drain flow channel 127. Of course, the raw water outlet 118 may also be directly communicated with the first sewage drain channel 127, so that the structure of the soft water valve is simpler.

In still other cases, the mixed solution of the jet outlet 162 is not limited to being drained to the soft water inlet 119, but may be drained to the raw water outlet 118 through the cooperation of the sub-valve assembly 130 and the main valve assembly 120, so that the mixed solution flows into the softening device 190 along the raw water outlet 118, the mixed solution washes the softened material in the softening device 190, and the washed sewage is drained to the sewage drain 115 through the sub-valve assembly 130. The route for feeding the mixed solution to the softening device 190 and discharging the sewage from the softening device 190 is various and can be selected as needed.

When the raw water in the auxiliary chamber 112 is introduced into the inflow port 161 through the auxiliary valve assembly 130, the mixed solution of the jet outlet 162 is fed into the soft water inlet 119 through the auxiliary valve assembly 130, the sewage of the raw water outlet 118 is discharged to the sewage outlet 115 through the main valve assembly 120, the first salt suction flow channel 1341 and the second salt suction flow channel 1342 of the auxiliary valve core 134 are communicated, the first salt suction flow channel 1341 is communicated with the auxiliary chamber 112 and the jet inlet 161, the second salt suction flow channel 1342 is communicated with the jet outlet 162 and the soft water inlet 119, the first sewage flow channel 127 of the main valve core 124 is communicated with the raw water outlet 118 and the sewage channel 1114 of the valve housing 110 (the end part of the sewage channel 1114 forms the sewage outlet 115), the raw water in the auxiliary chamber 112 enters the jet inlet 161 along the first salt suction flow channel 1341, the raw water and the salt solution are mixed in the jet flow channels to obtain mixed liquid, and the mixed liquid flows out along the jet outlet 162, the jet inlet 119, the raw water outlet 118, the first sewage flow channel 127 and the sewage outlet 115, so as to realize the salt suction and slow washing of the softening device 190.

Note that when the first salt suction flow passage 1341 communicates the sub-chamber 112 and the jet inlet 161, the sub-chamber 112 and the raw water inlet 113 communicate, so that raw water at the raw water inlet 113 can flow into the jet flow passage along the sub-chamber 112 and the jet inlet 161. Of course, the first salt suction flow path 1341 may also directly communicate the jet inlet 161 and the raw water inlet 113, so that raw water at the raw water inlet 113 may be delivered into the jet flow path through the jet inlet 161.

In some cases, the valve housing 110 is provided with a filtering channel 1115, a filtering piece is arranged in the filtering channel 1115, the filtering channel 1115 is communicated with the jet inlet 161 and the first salt absorption flow channel 1341, so that raw water flowing out of the first salt absorption flow channel 1341 is filtered by the filtering channel 1115, and then is sent to the softening device 190 along the jet flow channel and the second salt absorption flow channel 1342, and the raw water is used for regeneration of a softened material after being filtered.

The filter piece can be a filter screen, a filter element, a filter membrane and the like, and the filter piece has various structures. The filter can be fixed in the filter channel 1115, and the filter can be fixed through clamping, fastening piece connection, threaded connection and the like, so that the filter can be fixed in various modes and can be selected according to the needs. The filter element is detachably connected in the filter channel 1115, so that the filter element is convenient to replace.

Wherein, valve casing 110 is provided with the installation passageway, and ejector 160 demountable installation makes things convenient for ejector 160 dismouting in the installation passageway. In some cases, referring to fig. 35 and 40, the valve housing 110 is integrally formed with a mounting channel, which facilitates the processing of the valve housing 110 and also simplifies the structure of the soft water valve. Or the valve housing 110 is directly connected with the ejector 160 (not shown), the ejector 160 does not need to be installed in a channel, the independence of the ejector 160 is stronger, when the valve housing 110 is provided with the filtering channel 1115, the filtering channel 1115 can also be formed by a structural part independent of the valve housing 110, such as a pipe fitting detachably connected with the valve housing 110, and the pipe fitting can be integrally connected with the independent ejector 160, so that the number of parts is reduced. Based on the foregoing, the manner in which the ejector 160 and the filter element are mounted in the valve housing 110 is varied and may be selected as desired, and is not illustrated herein.

It should be noted that, referring to fig. 36 to 39, the ejector 160 may be a venturi structure, the ejector 160 is disposed at the left side of the valve housing 110, two channels are opened at the left side of the valve housing 110, the filter channel 1115 of the filter is installed at the lowest channel for filtering impurities, preventing the ejector 160 from being blocked, the installation channel for installing the ejector 160 is disposed above, and the salt tank connection port 1110 perpendicular to the water flowing direction of the pipe is installed at the side of the ejector 160. The salt tank connection port 1110 may be connected to the salt tank connection port 1110 via a hose, and salt is sucked during regeneration.

Referring to fig. 36 to 39, a first flow passage 164 and a second flow passage 165 are provided in the ejector 160, one end of the first flow passage 164 communicates with the suction port 163, the other end of the first flow passage 164 forms the jet inlet 161, one end of the second flow passage 165 communicates with the suction port 163, and the other end of the second flow passage 165 forms the jet outlet 162. A jet restrictor 166 is inserted at the end of the first flow passage 164 to regulate the flow of the jet 160.

Next, the structure of the sub spool 134 forming the first and second salt suction passages 1341 and 1342 will be described.

Referring to fig. 24, the auxiliary valve core 134 includes an auxiliary static valve sheet 132 and an auxiliary dynamic valve sheet 131, the auxiliary dynamic valve sheet 131 is connected to the auxiliary driving part 135, the auxiliary static valve sheet 132 is fixed to the valve housing 110, the auxiliary static valve sheet 132 is configured with a salt suction water injection hole 1324, a brine hole 1323 and a softening connection hole 1322, the auxiliary dynamic valve sheet 131 is configured with an auxiliary valve water inlet 1314 and an auxiliary valve first groove 1311, the auxiliary valve water inlet 1314 is communicated with the auxiliary cavity 112, the salt suction water injection hole 1324 is communicated with the jet inlet 161, the auxiliary valve water inlet 1314 and the salt suction water injection hole 1324 are communicated to form a first salt suction flow channel 1341, the brine hole 1323 is communicated with the jet outlet 162, the softening connection hole 1322 is communicated with the soft water inlet 119, and the brine hole 1323 is communicated with the second salt suction flow channel 1342 through the auxiliary valve first groove 1311 and the softening connection hole 1322.

It will be appreciated that the auxiliary valve water inlet 1314 and the saline fill hole 1324 communicate to form a first saline flow path 1341, such that the first saline flow path 1341 may communicate with the auxiliary chamber 112 and the jet inlet 161, and water within the auxiliary chamber 112 may flow into the jet flow path through the first saline flow path 1341. The brine hole 1323 and the softening connection hole 1322 are communicated with each other through the auxiliary valve first groove 1311 to obtain a second brine suction flow passage 1342, so that the second brine suction flow passage 1342 can be communicated with the jet outlet 162 and the soft water inlet 119, mixed liquid obtained by mixing raw water and brine in the jet flow passage can flow to the soft water inlet 119 through the second brine suction flow passage 1342, and then the mixed liquid enters the softening device 190 from the soft water inlet 119, so that brine is conveyed into the softening device 190. That is, in the salt suction mode, raw water flows along the paths of the sub chamber 112, the sub valve water inlet 1314, the salt suction water injection hole 1324, the jet inlet 161, the jet outlet 162 and the soft water inlet 119, after raw water enters the jet inlet 161, salt solution in the salt tank 200 enters the suction inlet 163 along the salt tank connection port 1110 under the negative pressure of raw water, so that the salt solution and raw water are mixed in the jet flow channel to obtain a mixed solution, and the mixed solution flows along the paths of the jet outlet 162, the salt water hole 1323, the sub valve first groove 1311 and the softening connection hole 1322, and the mixed solution enters the softening device 190 through the softening connection hole 1322, and is delivered according to the aforementioned paths.

The raw water of the sub-valve water inlet 1314 comes from the sub-chamber 112, and the raw water in the sub-chamber 112 comes from the raw water inlet 113.

In some cases, referring to fig. 41 and 42, the valve housing 110 includes a communication passage 1113, and the communication passage 1113 communicates with the sub-chamber 112 and the raw water inlet 113, so that raw water can be transferred to the sub-chamber 112 along the raw water inlet 113 and the communication passage 1113, a flow path for transferring raw water can be simplified, and a structure of the soft water valve can be simplified.

It is understood that the outlet of the communication channel 1113 communicates with the sub-chamber 112, and the inlet of the communication channel 1113 is on-off adjustable with the raw water inlet 113 through the main spool 124. By driving the main valve core 124 by the main driving part 125, the main valve core 124 can be switched between a third main valve position for communicating the communication channel 1113 with the raw water inlet 113 and a first main valve position for communicating the main cavity 111 with 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 channel 1113, so that the on-off adjustment of the communication channel 1113 and the raw water inlet 113 is realized, and the on-off adjustment of the auxiliary cavity 112 and the raw water inlet 113 is realized.

In the salt absorbing mode, the communication passage 1113 communicates with the raw water inlet 113 through the main spool 124, and raw water flows into the sub-chamber 112 through the raw water inlet 113, the main spool 124, and the communication passage 1113. Then, a part of the water in the sub chamber 112 flows to the soft water inlet 119 through the sub spool 134, and in the course of flowing to the soft water inlet 119, the raw water is mixed with the brine in the brine tank 200, and the mixed solution of the raw water and the brine flows to the soft water inlet 119 and enters the softener 190 from the soft water inlet 119. Another portion of the water in the secondary chamber 112 may then flow to the soft water outlet 114 so that the user may still have water available in the salt-suction mode, at which point it is used to draw raw water from the soft water outlet 114.

The above description has been made on the structure and state of the sub-valve assembly 130 in the salt absorbing mode, that is, on the path of the mixed solution to be fed to the softening device 190, and the following description has been made on the flow path of the sewage generated after the regeneration of the softened material in the softening device 190 by the mixed solution.

Referring to fig. 23, in the salt absorbing mode, the first drain flow path 127 of the main valve core 124 communicates, and the first drain flow path 127 communicates the raw water outlet 118 with the drain passage 1114 of the valve housing 110, so that the raw water outlet 118, the first drain flow path 127 and the drain passage 1114 communicate.

It will be appreciated that after the mixed liquor of raw water and brine enters the softening device 190, sewage flows along the paths of the raw water outlet 118, the first sewage flow path 127 and the sewage passage 1114, so that the sewage can be discharged out of the valve housing 110.

Note that the raw water outlet 118 may be directly connected to the first drain flow passage 127, or may be connected to the first drain flow passage 127 through the main chamber 111. When the raw water outlet 118 is communicated with the first sewage drainage channel 127 through the main cavity 111, the sewage is discharged out of the valve housing 110 along the raw water outlet 118, the main cavity 111, the first sewage drainage channel 127 and the sewage drainage channel 1114, the main water production channel 126 is disconnected at this time, and the main cavity 111 and the raw water inlet 113 are disconnected, so that the sewage in the main cavity 111 cannot be mixed with the raw water, the raw water at the raw water inlet 113 can be prevented from being polluted, the raw water inlet 113 is ensured to flow into the auxiliary cavity 112 instead of the sewage, the auxiliary cavity 112 is communicated with the soft water outlet 114, namely, the water used by a user is the water in the auxiliary cavity 112, and the raw water instead of the sewage is ensured to be used by the user when the soft water valve is in a salt absorption mode.

It should be noted that when the soft water valve is in the backwash mode and the salt suction mode, the flow paths of the main spool 124 are the same, so that the soft water valve can discharge sewage out of the valve housing 110 in both the salt suction mode and the backwash mode, and the two modes share one sewage drainage flow path, the structure of the main spool 124 can be simplified.

The main valve core 124 includes a main static valve plate 122 and a main valve plate 121, the main valve plate 121 is connected to the main driving portion 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 drain hole 1222, the main valve plate 121 is provided with a main valve water inlet 1211, the main valve drain hole 1222 is communicated with the drain channel 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 drain hole 1222 are communicated to form a first drain runner 127. The main valve body 124 is driven to the third main valve position by the main driving part 125 such that the main valve body 124 forms the first sewage flow passage 127, and the raw water outlet 118 and the sewage flow passage 1114 are communicated by the first sewage flow passage 127 such that sewage in the valve housing 110 can be discharged.

It will be appreciated that the first drain flow path 127 formed by the communication of the main valve water inlet 1211 and the main valve drain hole 1222 may communicate with the raw water outlet 118 and the drain passage 1114, so that sewage may flow along the raw water outlet 118, the main valve water inlet 1211, the main valve drain hole 1222 and the drain passage 1114 and be discharged out of the valve housing 110, thereby realizing the drainage of sewage.

Of course, the main static valve plate 122 may also be provided with two main valve drain holes 1222 (not shown), one main valve drain hole 1222 is communicated with the raw water outlet 118, the other main valve drain hole 1222 is communicated with the drain outlet 115 of the valve housing 110, and the two drain holes are communicated through the groove body of the main valve plate 121, so that the sewage in the softening device 190 can be discharged.

Next, the water injection mode performed by the sub-valve element 134 will be described in the case where the valve housing 110 has a related structure such as a jet flow passage.

In the water injection mode, referring to fig. 21, the water injection flow passage 137 of the sub-cartridge 134 is communicated, the water injection flow passage 137 is communicated with the jet inlet 161 and the soft water inlet 119, and the main chamber 111 is communicated with 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 flow passage 137, the jet flow passage and the salt tank connection port 1110 are communicated, 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 flow passage 137, the jet flow passage and the salt tank connection port 1110, and then is introduced into the salt tank 200 through the salt tank connection port 1110.

It should be noted that, here, a path for feeding soft water into the salt tank 200 is provided, a path for flowing soft water out of the softening device 190 is provided, a path for flowing raw water into the softening device 190 is not described, and the path for flowing raw water into the softening device 190 may refer to the above-described water making mode, that is, the main water making flow path 126 is communicated, and raw water at the raw water inlet 113 is fed to the raw water outlet 118, but may be other paths.

It will be appreciated that the jet inlet 161 communicates with the soft water inlet 119 such that soft water can flow into the jet flow passage through the jet inlet 161, at which time the jet outlet 162 is closed and the suction inlet 163 communicates with the brine tank connection port 1110 such that water flows through the jet inlet 161 to the suction inlet 163 and then to the brine tank connection port 1110.

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, the auxiliary static valve plate 132 is fixed to the valve housing 110, the auxiliary static valve plate 132 is configured with a softening connection hole 1322 and a salt-absorbing water injection hole 1324, the auxiliary dynamic valve plate 131 is configured with an auxiliary valve water inlet 1314, the salt-absorbing water injection hole 1324 is communicated with the jet inlet 161, the softening connection hole 1322 is communicated with the soft water inlet 119, the softening connection hole 1322, the auxiliary valve water inlet 1314 and the salt-absorbing water injection hole 1324 are communicated to form a water injection flow channel 137, in a water injection mode, the jet outlet 162 is closed, so that water flows into the jet flow channel from the salt-absorbing water injection hole 1324, and water in the jet flow channel flows into the salt box connection port 1110 through the suction inlet 163. The softening connection hole 1322, the sub-valve water inlet 1314, the salt-suction water injection hole 1324, and the jet inlet 161 are communicated so that the soft water at the soft water inlet 119 can flow into the jet flow passage through the jet inlet 161.

When the soft water is delivered into the jet flow passage, the jet outlet 162 is closed, the jet inlet 161 is communicated with the salt water suction hole 1324, the suction inlet 163 is communicated with the salt box connection port 1110, so that water flows into the jet inlet 161 through the salt water suction hole 1324, and the water in the jet flow passage flows to the salt box connection port 1110 through the suction inlet 163.

Based on the fact that the jet outlet 162 corresponds to the salt water hole 1323, the auxiliary movable valve plate 131 can move to close the salt water hole 1323, closing of the jet outlet 162 is achieved, and water in the jet flow passage enters the salt box connecting port 1110 through the suction inlet 163.

In connection with the above description of the valve types of the main valve assembly 120 and the auxiliary valve assembly 130, when the auxiliary valve assembly 130 is a disc valve, the auxiliary driving portion 135 is configured to drive the auxiliary moving valve plate 131 to rotate relative to the auxiliary static valve plate 132, so as to switch the auxiliary valve element 134 between a position where the water injection flow passage 137 communicates and a position where the first salt suction flow passage 1341 and the second salt suction flow passage 1342 communicate.

The secondary driving portion 135 is configured to drive the secondary moving valve plate 131 to rotate relative to the secondary static valve plate 132, so that the secondary valve element 134 is switched between a position where the water injection flow channel 137 is communicated and a position where the jet outlet 162 is communicated with the soft water inlet 119.

It is understood that the sub-valve plate 131 is driven to rotate by the sub-driving part 135, so that the sub-valve element 134 is switched between the second sub-valve position corresponding to the water injection mode and the third sub-valve position corresponding to the salt suction mode. When the soft water valve is in the water injection mode, that is, the auxiliary valve core 134 is in the second auxiliary valve position, the water injection flow passage 137 of the auxiliary valve core 134 is communicated, so that the soft water inlet 119 can be communicated with the jet inlet 161 through the water injection flow passage 137, soft water at the soft water inlet 119 can flow into the jet flow passage through the water injection flow passage 137 and the jet inlet 161 and then flow into the salt tank connection port 1110, and water injection operation of the salt tank 200 is realized. When the soft water valve is in the salt absorbing mode, that is, the auxiliary valve core 134 is in the third auxiliary valve position, the auxiliary valve core 134 is communicated with the jet outlet 162 and the soft water inlet 119, so that the mixed solution after raw water and brine 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, and brine injection operation of the softening device 190 is realized.

It should be noted that when the secondary spool 134 is in the second secondary valve position, the primary spool 124 is in the first primary valve position, and when the secondary spool 134 is in the third secondary valve position, the primary spool 124 is in the third primary valve position. That is, when the soft water valve is switched between the water filling mode and the salt absorbing mode, the main driving part 125 drives the main valve body 124 to change between the first main valve position and the third main valve position to achieve the switching of the water filling mode and the salt absorbing mode.

After the water injection mode and the salt suction mode, the regeneration of the softened material in the softening device 190 is realized, and the softening device 190 needs to be cleaned, namely, the soft water valve is controlled to execute a cleaning mode, and the cleaning mode comprises at least one of a backwashing mode and a positive washing mode, so that the softening device 190 and the soft water valve are ensured to be cleaned.

The backwash mode will be described below.

Referring to fig. 9 to 14 and 25 to 27, in the backwash mode, backwash flow passages of the sub spool 134 are communicated, backwash flow passage is communicated with the soft water inlet 119 and the raw water inlet 113, and the main driving part 125 is used for driving the main spool 124 to move to the first drain flow passage 127 to be communicated, and the first drain flow passage 127 is communicated with the raw water outlet 118 and the drain outlet 115 of the valve housing 110.

It is understood that the backwash flow passage communicates the soft water inlet 119 and the raw water inlet 113 so that raw water can flow along the raw water inlet 113 and the soft water inlet 119 and then flow into the softener 190 from the soft water inlet 119 and out of the softener 190 from the raw water outlet 118, thereby performing backwash operation of the softener 190. Since the first drain flow path 127 communicates the raw water outlet 118 and the drain outlet 115 of the valve housing 110, the sewage flowing out of the raw water outlet 118 may be discharged out of the valve housing 110 along the first drain flow path 127 and the drain outlet 115, thereby realizing the drain of the soft water valve.

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, the auxiliary static valve plate 132 is fixed to the valve housing 110, the auxiliary static valve plate 132 is configured with a softening connection hole 1322, the auxiliary dynamic valve plate 131 is configured with an auxiliary valve water inlet 1314, the softening connection hole 1322 is communicated with the soft water inlet 119, the auxiliary valve water inlet 1314 is communicated with the raw water inlet 113, and the auxiliary valve water inlet 1314 is communicated with the softening connection hole 1322 to form a backwash flow channel.

It will be appreciated that the sub valve core 134 is driven to move to the first sub valve position by the sub driving part 135 such that the sub valve water inlet 1314 and the soft water inlet 119 are communicated to form a backwash flow passage, and the backwash flow passage may be communicated with the raw water inlet 113 and the soft water inlet 119 such that the raw water inlet 113, the backwash flow passage and the soft water inlet 119 are communicated, and raw water may flow into the softener 190 along the raw water inlet 113, the backwash flow passage and the soft water inlet 119.

Note that the sub-valve water inlet 1314 may communicate with the sub-chamber 112, and the sub-chamber 112 communicates with the raw water inlet 113 through the main spool 124, so that the raw water inlet 113, the sub-chamber 112, the sub-valve water inlet 1314, the soft water inlet 119, and the raw water may flow along the paths of the raw water inlet 113, the sub-chamber 112, the sub-valve water inlet 1314, the soft water inlet 119, and the soft water inlet 1322.

Wherein, in the backwash mode, the backwash flow passage communicates with the soft water inlet 119 and the sub chamber 112, and the sub chamber 112 communicates with the raw water inlet 113 such that the raw water inlet 113, the sub chamber 112, the backwash flow passage and the soft water inlet 119 communicate. The raw water may flow along the paths of the raw water inlet 113, the auxiliary chamber 112, the backwash flow passage and the soft water inlet 119, and when the raw water flows to the auxiliary chamber 112, a part of the raw water flows along the paths of the backwash flow passage and the soft water inlet 119, and another part of the raw water flows to the soft water outlet 114, so that a user can obtain raw water at the soft water outlet 114, and it is achieved that the user still has water available when the soft water valve is in a backwash state.

It should be noted that, in both the backwash mode and the salt suction mode, the first drain flow passage 127 is used to drain water, that is, in the backwash mode and the salt suction mode, the main valve element 124 is in the same state, so that the structure of the main valve assembly 120 and the flow path arrangement in the soft water valve can be simplified.

In the salt suction mode and the backwash mode, the paths of the raw water flowing into the auxiliary chamber 112 are the same, the main valve assembly 120 is used for communicating the raw water inlet 113 with the auxiliary chamber 112, and the main valve assembly 120 is used for disconnecting the raw water inlet 113 from the main chamber 111, so that the structure of the main valve assembly 120 and the flow path arrangement in the soft water valve can be simplified.

It can be further understood that in the backwash mode and the salt absorbing mode, the main valve assembly 120 is in the same state, and the water is drained to the outside of the soft water valve through the main valve assembly 120, but the drainage flow path is not limited to the first drain flow passage 127, and may be a structure not illustrated in the figure, for example, the above-mentioned technical scheme that the main static valve plate 122 is provided with two drain holes may be referred to in detail, and details are not repeated here. That is, during the switching of the salt suction mode to the backwash mode, the state of the adjustable secondary valve assembly 130 and the state of the main valve assembly 120 may remain unchanged.

In the backwash mode and the water producing mode, the state of the auxiliary valve assembly 130 may be the same, the auxiliary valve element 134 is used to communicate the soft water inlet 119 with the auxiliary chamber 112, and the soft water valve can be switched between the water producing mode and the backwash mode by switching the position of the main valve element 124. In the backwash mode, the sub valve assembly 130 communicates the soft water inlet 119 with the sub chamber 112 in order to allow raw water in the sub chamber 112 to flow into the softening device 190 through the soft water inlet 119; in the water making mode, the sub valve assembly 130 communicates the soft water inlet 119 and the sub chamber 112 in order to allow the soft water at the soft water inlet 119 to flow to the soft water outlet 114 through the sub chamber 112. By sharing the sub valve element 134 in one state in the backwash mode and the water producing mode, the structure of the sub valve assembly 130 can be simplified.

The backwash mode is described above, and the normal backwash mode is described below.

Referring to fig. 9 to 14 and 28 to 30, the valve housing 110 is provided with a drain 115, and in the forward washing mode, the sub-driving part 135 serves to drive the sub-spool 134 to move to communicate with the forward washing passage 138, and the forward washing passage 138 communicates the soft water inlet 119 with the drain 115. The secondary valve core 134 is driven to move to the fourth secondary valve position by the secondary driving part 135 so that the forward washing flow passage 138 is communicated, at this time, the main water flow passage 126 of the main valve core 124 is communicated with the main chamber 111 and the raw water inlet 113 so that raw water can flow along the paths of the raw water inlet 113, the main chamber 111, the raw water outlet 118 and the soft water inlet 119, and the sewage outlet 115, and the forward washing flow passage 138 is communicated with the soft water inlet 119 and the sewage outlet 115 so that water can flow along the paths of the soft water inlet 119 and the sewage outlet 115, thereby realizing the discharge of sewage out of the valve housing 110 in the forward washing mode.

It will be appreciated that the primary spool 124 is in the first primary valve position and the soft water valve is switched between the water making mode, the water filling mode and the forward washing mode by switching the position of the secondary spool 134. The main spool 124 is in the first main valve position when in the water making mode, the water filling mode, and the normal washing mode, i.e., the state of the main spool 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 driving part 135 drives the auxiliary valve core 134 to perform corresponding position switching, so that the soft water valve can be switched among a water making mode, a water filling mode and a normal washing mode, the control of the soft water valve is simpler, and the structure of the soft water valve is simplified.

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, the auxiliary static valve plate 132 is fixed to the valve housing 110, the auxiliary static valve plate 132 is configured with a softening connection hole 1322 and an auxiliary valve drain hole 1321, the softening connection hole 1322 is communicated with the soft water inlet 119, the auxiliary valve drain hole 1321 is communicated with the drain outlet 115, and the softening connection hole 1322 and the auxiliary valve drain hole 1321 are communicated through the auxiliary valve core 134 to form the forward washing flow channel 138.

It is understood that the forward washing passage 138 formed by the communication of the softening connection hole 1322 and the sub-valve drain hole 1321 may communicate the soft water inlet 119 with the drain 115 such that the soft water inlet 119, the forward washing passage 138 and the drain 115 communicate. In the forward washing mode, raw water flows into the softener 190 through the raw water inlet 113, the main chamber 111 and the raw water outlet 118, forward washing operation is performed on the softener 190, sewage after washing the softener 190 is discharged from the soft water outlet 114, and then the sewage flows along the paths of the soft water inlet 119, the forward washing flow path 138 and the sewage discharge outlet 115 and is discharged out of the valve housing 110, thereby realizing sewage discharge in the forward washing mode.

The auxiliary movable valve plate 131 is provided with an auxiliary valve water inlet 1314, the auxiliary valve water inlet 1314 is communicated with the auxiliary cavity 112, and the softening connecting hole 1322 is communicated with the auxiliary valve drain hole 1321 through the auxiliary valve water inlet 1314 to form a positive washing flow channel 138.

It will be appreciated that the softening connection hole 1322 communicates with the auxiliary valve drain hole 1321 through the auxiliary valve water inlet 1314, and the auxiliary valve water inlet 1314 communicates with the auxiliary chamber 112, so that water at the soft water inlet 119 may partially flow along the forward washing channel 138 to the drain 115, and partially flow along the softening connection hole 1322 and the auxiliary valve water inlet 1314 to the auxiliary chamber 112, and since the soft water valve has been backwashed before the forward washing mode, the salt content of the sewage generated in the forward washing mode is low, and the sewage can be used, and when the user needs to use water in the forward washing mode, the water in the auxiliary chamber 112 is discharged through the soft water outlet 114 for the user.

It should be noted that water at the soft water inlet 119 may also flow along the soft connection hole 1322 and the auxiliary valve water inlet 1314 into the auxiliary chamber 112, and then a portion of the water in the auxiliary chamber 112 flows along the path of the auxiliary valve water inlet 1314 and the auxiliary valve drain hole 1321 to the drain 115, and another portion flows to the soft water outlet 114, so that water is still available to the user in the forward washing mode.

It should be noted that in the forward washing mode, the softening connection hole 1322 communicates with the sub-valve water inlet 1314, and the softening connection hole 1322 and the sub-valve water inlet 1314 are used to form the sub-water making flow path 136 in addition to the forward washing flow path 138. That is, the auxiliary valve core 134 has the function of communicating the soft water inlet 119 with the auxiliary chamber 112 in both the normal washing mode and the water making mode, and the auxiliary valve core 134 has the flow passage formed by the communication of the softening connection hole 1322 with the auxiliary valve water inlet 1314, but the auxiliary valve drain hole 1321 of the auxiliary valve core 134 is also communicated with the auxiliary valve water inlet 1314 in the normal washing mode.

Wherein, in the forward washing mode, the forward washing flow channel 138 is communicated with the soft water inlet 119 and the blowdown passage 1114 of the valve housing 110, the blowdown outlet 115 is formed at the end part of the blowdown passage 1114, the raw water outlet 118 is communicated with the raw water inlet 113, raw water in the soft water valve enters the softening device 190 through the raw water outlet 118, water in the softening device 190 is introduced into the soft water valve through the soft water inlet 119 so as to be discharged through the forward washing flow channel 138 of the auxiliary valve core 134 and the blowdown passage 1114 of the valve housing 110, and the sewage discharge of the clean softening device 190 is realized.

It is understood that in the case where the main spool 124 is provided with the main process water flow passage 126, the raw water outlet 118 communicates with the raw water inlet 113 through the main process water flow passage 126 in the forward washing mode. It will also be appreciated that the state of main spool 124 in the forward wash mode is the same as the state of main spool 124 in the water-producing mode, i.e., main spool 124 is in the first main valve position, and that when main spool 124 is in the first main valve position, the water-producing mode and the forward wash mode can be switched by adjusting the state of auxiliary spool 134.

The auxiliary driving part 135 is used for driving the auxiliary valve core 134 to rotate to be connected with or disconnected from the forward washing flow channel 138, that is, the auxiliary driving part 135 drives the auxiliary movable valve plate 131 to rotate relative to the auxiliary static valve plate 132, so that the state switching of the auxiliary valve core 134 can be realized, and the functional mode switching of the soft water valve can be further realized.

After the salt absorbing mode is performed by the soft water valve, the softening device 190 needs to be cleaned, and the cleaning mode of the softening device 190 may be at least one of the above-mentioned backwash mode and forward wash mode. When the washing mode includes a backwash mode or a forward washing mode, the softening device 190 may be washed by the backwash mode or the forward washing mode after the salt absorbing mode is performed; when the cleaning mode comprises a backwashing mode and a positive cleaning mode, after the salt absorbing mode is finished, the backwashing mode or the positive cleaning mode can be executed first, and can be selected according to requirements. In some cases, after the salt suction mode, a backwash mode is performed first, and then a forward wash mode is performed.

It should be noted that, the hole of the main static valve plate 122 and the hole of the auxiliary static valve plate 132 are provided with openings corresponding to and communicating with the hole on the valve housing 110, so as to ensure that water can flow out through the hole of the static valve plate.

The flow paths corresponding to the respective modes of the soft water valve are described above, and the control method of the soft water valve is described below.

Based on the foregoing, the main valve assembly 120 includes two main valve positions, the sub-valve assembly 130 includes a plurality of sub-valve positions, and the positional relationship of the main valve assembly 120 and the sub-valve assembly 130 is described.

It will be appreciated that the primary drive portion 125 is configured to drive the primary spool 124 between the first primary valve position and the third primary valve position, and the secondary drive portion 135 is configured to drive the secondary spool 134 between the plurality of secondary valve positions to switch the soft water valve between the water making mode, the water filling mode, the salt absorbing mode, and the cleaning mode.

Referring to fig. 17, 20, 23, 26 and 29, the primary spool 124 is switched between the first primary valve position and the third primary valve position, i.e., the primary spool 124 is positioned in the same position in at least two modes, which simplifies the manner in which the primary spool 124 is controlled.

In some cases, referring to fig. 17, 20 and 29, in the first main valve position, the main water flow channel 126 of the main valve 124 communicates with the main chamber 111 and the raw water inlet 113, and at the same time, the main chamber 111 communicates with the raw water outlet 118, that is, the raw water of the raw water inlet 113 can be delivered to the raw water outlet 118 through the main valve 124, so as to realize the process of delivering raw water to the softening device 190, and at this time, the soft water valve is switched between the water making mode and the water filling mode by switching the positions of the auxiliary valve 134.

When the wash mode includes a forward wash mode, the primary spool 124 is in the first primary valve position, which may be switched by the position of the secondary spool 134, such that the soft water valve switches to the forward wash mode. The "main water flow channel 126" may refer to the above-mentioned water making mode, water filling mode and normal washing mode, for example, the main valve water inlet 1211 of the main valve plate 121 and the main valve water inlet 1221 of the main static valve plate 122 are communicated to form the main water flow channel 126.

In other cases, referring to fig. 23 and 26, in the third main valve position, the main valve spool 124 is in the first drain flow path 127 of the main valve spool 124, the main water flow path 126 is disconnected, and the first drain flow path 127 communicates the raw water outlet 118 with the drain passage 1114 of the valve housing 110, so that the sewage is discharged along the raw water outlet 118, the first drain flow path 127, and the drain passage 1114. In the third main valve position, the main spool 124 is used to direct the dirty water from the softener 190. In the mode in which sewage is to be discharged, the main valve 124 may be switched to the third main valve position, and at this time, raw water may be supplied to the sub-chamber 112 through the main valve 124, and then the flow of water may be controlled through the sub-valve 134, thereby performing operations such as supplying water to the brine tank 200 and supplying water to the softener 190.

When the cleaning mode includes a backwash mode, the main valve spool 124 is in the third main valve position and the soft water valve is switched between the saline-sucking mode and the backwash mode by switching the position of the auxiliary valve spool 134. It can be understood that the salt suction mode and the backwashing mode, both of which are the salt suction mode and the backwashing mode, are the modes in which raw water is conveyed to the auxiliary chamber 112 through the main valve core 124, water at the auxiliary chamber 112 is conveyed to the softening device 190 by the auxiliary valve core 134, sewage in the softening device 190 is led out through the main valve core 124, and the two modes are different in flow passage communicated with the auxiliary valve core 134. In the salt suction mode, the first salt suction passage 1341 and the second salt suction passage 1342 of the sub valve element 134 are communicated, and in the backwash mode, the backwash flow passages of the sub valve element 134 are communicated.

The above description has been given of two positions of the main valve assembly 120, and the following description will be given of respective modes in connection with the positions of the main valve assembly 120 and the sub-valve assembly 130.

Referring to fig. 21, in the water filling mode, the sub spool 134 is in the second sub valve position, the main spool 124 is in the first main valve position, the main spool 124 is for supplying water to the softener 190, and the sub spool 134 is for supplying soft water in the softener 190 to the brine tank connection port 1110. In the second sub valve position, the water injection flow passage 137 of the sub valve body 134 communicates, and the water injection flow passage 137 communicates the soft water inlet 119 with the salt tank connection port 1110. And in the second auxiliary valve position, the auxiliary valve core 134 also communicates with the soft water inlet 119 and the auxiliary chamber 112, so that water at the soft water inlet 119 can flow into the auxiliary chamber 112, and then water can flow from the auxiliary chamber 112 to the soft water outlet 114, ensuring that water is available to the user in the water filling mode.

Referring to fig. 24, in the salt suction mode, the sub valve core 134 is at the third sub valve position, the main valve core 124 is at the third main valve position, the main valve core 124 is used for blocking the raw water inlet 113 and the main cavity 111, the sub valve core 134 is used for introducing raw water into the ejector 160, sucking the salt solution in the salt tank connection port 1110 into the ejector 160 under the driving of the flowing power of the raw water, and delivering the mixed solution in the ejector 160 into the softening device 190, and water in the softening device 190 is discharged along the valve housing 110 through the main valve core 124. In the third auxiliary valve position, the first salt-absorbing flow channel 1341 and the second salt-absorbing flow channel 1342 of the auxiliary valve core 134 are communicated, the jet inlet 161 of the jet flow channel is communicated with the auxiliary cavity 112 through the first salt-absorbing flow channel 1341, the suction inlet 163 of the jet flow channel is communicated with the salt box connection port 1110, and the jet outlet 162 of the jet flow channel is communicated with the soft water inlet 119 through the second salt-absorbing flow channel 1342. In the salt absorbing mode, the main valve core 124 is further used for communicating the raw water inlet 113 and the auxiliary cavity 112, so that raw water can flow into the auxiliary cavity 112, raw water in the auxiliary cavity 112 can flow into the soft water outlet 114 in addition to the ejector 160, so that a user can use raw water in the salt absorbing mode, and the auxiliary valve core 134 is further used for separating the soft water inlet 119 and the auxiliary cavity 112, so that pollution of the salt water at the soft water inlet 119 to the raw water in the auxiliary cavity 112 can be avoided.

Referring to fig. 27, when the washing mode includes a backwash mode in which the sub spool 134 is in the first sub valve position and the main spool 124 is in the third main valve position, the sub spool 134 is used to feed raw water into the softener 190 and water in the softener 190 is discharged along the valve housing 110 through the main spool 124. In the first secondary valve position, the backwash flow passage of the secondary spool 134 communicates with the backwash flow passage communicating the soft water inlet 119 with the secondary chamber 112. In the third main valve position, the main valve 124 blocks the raw water inlet 113 and the main chamber 111, the main valve 124 communicates the raw water inlet 113 and the auxiliary chamber 112, so that raw water can enter the auxiliary chamber 112, then a part of raw water flows from the auxiliary chamber 112 into the softening device 190, and another part of raw water flows to the soft water outlet 114, so that water is available for a user during backwashing.

Referring to fig. 30, when the washing mode includes a forward washing mode in which the sub spool 134 is in the fourth sub valve position and the main spool 124 is in the first main valve position, the main spool 124 is used to feed raw water into the softener 190, and water in the softener 190 is discharged along the valve housing 110 through the sub spool 134. In the third secondary valve position, the forward flush passage 138 of the secondary spool 134 communicates with the forward flush passage 138 communicating the soft water inlet 119 with the trapway 1114 of the valve housing 110. It should be noted that before the soft water valve is in the forward washing mode, the soft water valve is controlled to be in the back washing mode, namely, the soft water valve is cleaned first, so that the salinity of water in the soft water valve is reduced. Then the soft water valve is controlled to be in a forward washing mode, at the moment, the salinity of water in the soft water valve is low, a user can use the soft water valve, and the cleaning step of the bottom of the water pocket understood by the forward washing operation can be realized, namely, after the soft water valve is in a backwashing mode, the water in the soft water valve is in a normal use state, so that the water can be used by the user in the forward washing mode.

Referring to fig. 44, when the soft water valve includes a water making mode, a water filling mode, and a salt absorbing mode, the sub driving part 135 is configured to drive the sub valve body 134 to rotatably switch between a first sub valve position, a second sub valve position, and a third sub valve position, which are sequentially provided along the circumferential direction of the sub valve body 134, so that the sub valve body 134 can be conveniently position-adjusted. The purge mode includes a normal purge mode, and the sub driving part 135 is configured to drive the sub spool 134 to rotationally switch between a first sub valve position, a second sub valve position, a third sub valve position, and a fourth sub valve position, which are sequentially provided in the circumferential direction of the sub spool 134.

The state and the functional mode of the soft water valve are not described herein, and the above description of each mode may be combined.

In the operation process of the soft water valve, the soft water valve is mainly in a water making mode, when the softened material in the softening device 190 needs to be regenerated, water is injected into the salt tank 200, the water injection mode is executed, then the salt absorbing mode is executed, the mixed solution of the salt solution with the regeneration function is sent into the softening device 190, then the cleaning mode is executed, and when the cleaning mode comprises a positive cleaning mode and a back cleaning mode, the back cleaning mode can be executed first, and then the positive cleaning mode is executed.

In the water-making mode, main spool 124 is in a first main valve position and auxiliary spool 134 is in a first auxiliary valve position; when the water fill mode is to be performed, the position of the main spool 124 need not be adjusted and the auxiliary spool 134 is adjusted to the second auxiliary valve position; after the water injection mode, the salt tank 200 needs to perform salt melting for a preset period of time to obtain salt solution, at this time, the salt tank is adjustable to a water making mode, the position of the main valve core 124 does not need to be adjusted, and the auxiliary valve core 134 can be restored to the first auxiliary valve position; after the salt melting is completed, the salt absorbing mode is performed, requiring the main spool 124 to be adjusted to the third main valve position and the auxiliary spool 134 to be adjusted to the third auxiliary valve position. Taking the salt suction mode as an example, the backwash mode is performed first, at this time, the position of the main valve core 124 does not need to be adjusted, the auxiliary valve core 134 is adjusted to the first auxiliary valve position, then, in the normal wash mode, the main valve core 124 needs to be adjusted to the first main valve position, the auxiliary valve core 134 needs to be adjusted to the fourth auxiliary valve position, and the regeneration process of the softened material is completed. Finally, the soft water valve is adjusted to a water making mode, and the water making function is continuously executed.

In still other cases, referring to FIG. 43, main spool 124 further includes a second main valve position, and main spool 124 is adapted to switch between the first main valve position, the second main valve position, and the third main valve position. At the second main valve position, the main valve 124 blocks the raw water inlet 113 from the main cavity 111, the main valve 124 blocks the raw water inlet 113 from the auxiliary cavity 112, and controls the auxiliary driving part 135 to drive the auxiliary valve 134 to switch in position, at this time, raw water of the raw water inlet 113 does not enter the soft water valve, water stops entering the main cavity 111, the auxiliary cavity 112 and the softening device 190, raw water is completely blocked at the front end of the soft water valve, water cannot pass through the softening device and soft water cannot be generated, no raw water enters the main cavity and the auxiliary cavity, continuous pressure is not transmitted in the main cavity and the auxiliary cavity, the flow pressure of water received by the auxiliary valve 134 in the auxiliary cavity 112 is reduced, the resistance of water pressure to the position switching of the auxiliary valve 134 can be reduced, the position switching of the auxiliary valve 134 is more labor-saving, the driving force provided by the auxiliary driving part 135 to the auxiliary movable valve 131 can be reduced, the power consumption can be reduced, the loss of the auxiliary valve assembly 130 can be reduced, and the service life of the auxiliary valve assembly 130 and the service life of the soft water valve can be prolonged. The softening device, the main cavity and the auxiliary cavity do not have too large pressure, and the torque is not very large when the main valve core and the auxiliary valve core rotate, so that the motor is convenient to drive.

In the second main valve position, raw water may pass from the bypass valve and then flow into the soft water passage of the valve head for use by a user. Therefore, the state can meet the functional requirement that the user only uses pure tap water. The main spool 124 is in the second main valve position and the controllable secondary drive portion 135 drives the secondary spool 134 to switch between the plurality of secondary valve positions. Before the position of the auxiliary valve core 134 needs to be switched, the position of the main valve core 124 is switched to the second main valve position, so that the resistance of the water pressure to the position switching of the auxiliary valve core 134 can be reduced, the position switching of the auxiliary valve core 134 is more labor-saving, and the operation is simple and convenient.

In the second main valve position, the sub driving part drives the sub valve element to switch among a plurality of sub valve positions so that the state of the sub valve element corresponds to one of a water making mode, a water filling mode, a salt absorbing mode, a backwashing mode and a normal washing mode, such as one sub valve position for each mode, or one sub valve position is shared by the two modes.

In some cases, the placement of the secondary spool in the same secondary valve position (e.g., the first secondary valve position described above) may simplify the construction of the secondary spool in both the water-making mode and the backwash mode. Of course, other modes may share a common secondary valve position.

The main valve core can seal raw water and does not flow into the softening device and also does not flow into the auxiliary cavity, and water in the softening device and water in the auxiliary cavity can be reduced to flow into the salt tank at a plurality of auxiliary valve positions in the position switching process of the auxiliary valve core, so that inaccurate water injection of the salt tank is avoided.

It can be understood that when the water making mode is switched to the water filling mode, the position of the main valve core 124 needs to be adjusted to the second main valve position, then the position of the auxiliary valve core 134 is adjusted to the second auxiliary valve position, and after the auxiliary valve core 134 is adjusted, the main valve core 124 returns to the first main valve position, so that the water filling process can be executed; after the water injection is completed, the main valve core 124 is again adjusted to the second main valve position, the auxiliary valve core 134 is returned to the first auxiliary valve position, the main valve core 124 is then adjusted back to the first main valve position, the salt box connection port 1110 is in a salt melting state, the soft water valve is in a water making mode, and a user can take water. After the salt melting is completed, a salt absorbing mode is performed, at this time, the main valve core 124 is regulated and controlled to the second main valve position, the auxiliary valve core 134 is regulated and controlled to the third auxiliary valve position, and then the main valve core 124 is regulated and controlled to the third main valve position so as to execute the salt absorbing mode; after the salt suction mode is completed, the main valve core 124 is adjusted to a second main valve position, then the auxiliary valve core 134 is adjusted to a first auxiliary valve position, and then the main valve core 124 is adjusted to a third main valve position to execute the backwashing mode; after the backwash mode, the main valve element 124 is adjusted to the second main valve position, the auxiliary valve element 134 is adjusted to the fourth auxiliary valve position, and the main valve element 124 is adjusted to the first main valve position to execute the backwash mode. After the forward washing mode is completed, the main valve core 124 is regulated to the second main valve position, the auxiliary valve core 134 is regulated to the first auxiliary valve position, and the main valve core 124 is regulated to the first main valve position, so that water can be prepared.

Referring to fig. 43, the main valve first groove corresponds to the main valve water inlet hole, the main valve water inlet hole is completely covered and sealed by the main valve first groove, water cannot pass through, and raw water from the raw water inlet cannot enter the main chamber.

The main valve plate is provided with a main valve second groove body, and in the second main valve position, the orthographic projection of the main valve blow-off hole on the main valve plate is positioned in the main valve second groove, and the pressure of the main valve plate and the main static valve plate is balanced through the main valve blow-off hole and the main valve second groove body.

In the process that the main valve core is switched from the first main valve position or the third main valve position to the second main valve position, a part of the main valve water inlet hole is communicated with the main valve blow-down hole, the main valve blow-down hole is communicated with a blow-down outlet (the blow-down outlet is communicated with the external environment), the pressure in the softening device can be discharged through the main valve blow-down hole, the pressure at the bottom of the auxiliary movable valve plate is reduced, if the pressure is not discharged, the pressure in the softening device can be transmitted to the auxiliary movable valve plate through the auxiliary static valve plate and the softening connecting hole, and the torque of the auxiliary valve motor is increased. In the second main valve position, raw water does not flow into the softening device, and the pressure in the softening device is not increased after being released, so that the second main valve position has the function of releasing pressure and reducing the rotation torque of the auxiliary valve core.
