The water purification assembly 100 provided by the present application is suitable for refrigeration device such as refrigerators, ice bars, freezers, wine cabinets, and refrigeration cabinets, etc. The water purification assembly 100 provided by the present application is described in detail below with reference to specific embodiments.

Referring to FIG. 1, the present application provides a water purification assembly 100. The water purification assembly 100 includes an outer shell assembly 101, a filter element 103, an inner shell 102 and a support member 104. An accommodation chamber is provided inside the outer shell assembly 101. The filter element 103 is provided in the accommodation chamber. The inner shell 102 is provided between the outer shell assembly 101 and the filter element 103, and a first flow channel 1013 for flowing water body is provided between the inner shell 102 and the outer shell assembly 101. A second flow channel 1014 for allowing water body flow is provided between the inner shell 102 and the filter element 103.

The support member 104 is mainly used for supporting the filter element 103 in axial direction, so that there is a certain space between the filter element 103 and a bottom wall of the outer shell assembly 101, that is, a water storage chamber 1041 is provided between the filter element 103 and the bottom wall of the outer shell assembly 101. The water storage chamber 1041 is communicated with the first flow channel 1013 and the second flow channel 1014 respectively. A third flow channel 1031 is provided inside the filter element 103, which is equivalent to that, the filter element 103 is located between the second flow channel 1014 and the third flow channel 1031.

The first flow channel 1013 may be either an inlet flow channel or an outlet flow channel, the second flow channel 1014 may be either an inlet flow channel or an outlet flow channel, and the third flow channel 1031 may also be either an inlet flow channel or an outlet flow channel.

In case that both the first flow channel 1013 and the second flow channel 1014 are inlet flow channels, and the third flow channel 1031 is an outlet flow channel, the first flow channel 1013 may be communicated with a main water inlet 1051 of the water purification assembly 100, and the third flow channel 1031 may be communicated with a main water outlet 1052 of the water purification assembly 100.

During the operating procedure of the water purification assembly 100, the main water inlet 1051 is communicated with an external water source, and the water body flows from the main water inlet 1051 into the first flow channel 1013, and enters the water storage chamber 1041 through the first flow channel 1013 for storage. When a user uses purified water, the water stored in the water storage chamber 1041 first flows from the water storage chamber 1041 into the second flow channel 1014, enters the third flow channel 1031 from the second flow channel 1014 through the filter element 103, is sent to the main water outlet 1052 by the third flow channel 1031, and finally flows out from the main water outlet 1052.

It may be understood that by providing the water storage chamber 1041 for water storage and inner water passages in the water purification assembly 100, the water purification assembly 100 is more integrated, and the water purification assembly 100 not only has a purify function, but also has a water storage function. The water tank structure, which is provided independently from water purification assembly 100 in the related art, is replaced, that is, the water tank is canceled, thereby simplifying a structural design and reducing space occupied by the structure. Meanwhile, connect pipes and connect joints between the water tank and the water purification assembly 100 are canceled, which effectively avoids structural leakage risks, thereby making a product more reliable.

Referring to FIG. 1, it may be understood that the support member 104 may be provided at an inner wall surface of the outer shell assembly 101, and the water storage chamber 1041 is formed inside the support member 104. This is equivalent to that the support member 104 is clamped or lapped at the inner wall surface of the outer shell assembly 101, to prevent the filter element 103 from continuing to extend into the bottom wall of the outer shell assembly 101. There is certain space between the bottom wall of the outer shell assembly 101 and the support member 104, which then forms the water storage chamber 1041.

After the water body enters the water storage chamber 1041 through the first flow channel 1013, the water body may be temporarily stored in the water storage chamber 1041. The water storage chamber 1041 is equivalent to a water tank for water storage. Part of the water body in the water storage chamber 1041 enters the second flow channel 1014, and then penetrates from the second flow channel 1014 into the filter element 103 for filtering. The water body filtered by the filter element 103 flows out from the third flow channel 1031 inside the filter element 103.

By integrating the water storage chamber 1041 in the water purification assembly 100 for water storage, the water tank structure is canceled. Meanwhile, the connect pipes and the connect joints between the water tank and the water purification assembly 100 are also canceled, thereby simplifying the structure, reducing the space occupied by the structure and effectively avoiding the risk of water leakage. In addition, when purifying the water body, since the water storage chamber 1041 is integrated inside the water purification assembly 100, an input side of the filter element 103 is fully immersed in the water environment, ensuring that the filter element 103 has a better purification effect on the water.

Referring to FIG. 1, it may be further understood that the structural shape of the support member 104 is compatible with the structural shapes of the filter element 103 and the inner shell 102. In case that the inner shell 102 and the filter element 103 are both cylindrical structures, the support member 104 may also be a cylindrical structure. The support member 104 is fixedly provided at an inner wall surface of the inner shell 102. One side of the support member 104 may abut against the filter element 103 for blocking an end of the filter element 103. Another side of the support member 104 together with part of the inner wall surface of the outer shell assembly 101 and the bottom wall of the outer shell assembly 101 may form a space for water storage, that is, the water storage chamber 1041.

Meanwhile, a stopper (not shown in the figure) may be provided at the inner wall surface of the outer shell assembly 101 to limit an axial support of the inner shell 102, and then an end surface of one end of the inner shell 102 is flush with a surface of a side of the support member 104 facing the water storage chamber 1041. The water body passing through the first flow channel 1013 can directly enter the water storage chamber 1041 for storage. Moreover, a plurality of first water outlets 1042-4 are provided at the support member 104, and each first water outlet 1042-4 is communicated with the second flow channel 1014. The water in the water storage chamber 1041 passes through the first water outlet 1042-4 and enters the second flow channel 1014.

Referring to FIG. 1, it may be further understood that the inner shell 102 can extend to the bottom wall of the outer shell assembly 101, and there is a certain water-pass gap between the inner shell 102 and the inner wall surface of the outer shell assembly 101, which is equivalent to that the water storage chamber 1041 is separated from the first flow channel 1013. The water body in the second flow channel 1014 continues to enter the water-pass gap, and enters the water storage chamber 1041 from the water-pass gap. This is equivalent to that a water inlet path is extended. The water first entering the water storage chamber 1041 flows out from the first water outlet 1042-4 of the water storage chamber 1041, which is beneficial to that the water first entering a water purification module is filtered first and then flows out from the water purification module, thereby preventing the retention of stale water.

Openings may be opened at a bottom end of the inner shell 102 close to the outer shell assembly 101, that is, a plurality of openings may be opened at a side wall or an end surface of the inner shell 102 to form the first water inlet 1042-3 of the water storage chamber 1041.

Referring to FIG. 2, it may be understood that the structural shape of the support member 104 is adapted to the structural shapes of the filter element 103, the inner shell 102, etc., and may be a cylindrical structure for axially supporting the filter clement 103 and blocking an end of the filter element 103. An interior of the support member 104 is a hollow structure to form a water flow channel and a water storage space.

The support member 104 includes a support member body 1042 and a limit block 1043. The limit block 1043 is provided at an outer wall of the support member body 1042, which is equivalent to a connected protruded lug of the support member body 1042, and is suitable for abutting against or lapping on the inner wall surface of the outer shell assembly 101 to fix the support member body 1042.

The support member body 1042 has a first end 1042-1 and a second end 1042-2. The first end 1042-1 is formed with a first water inlet 1042-3. The first water inlet 1042-3 is communicated with the first flow channel 1013, so that the water in the first flow channel 1013 enters the water storage chamber 1041 through the first water inlet 1042-3. The second end 1042-2 is adapted to abut against the filter element 103, and is used to block an end of the filter element 103, so that the water in the water storage chamber 1041 is filtered by the filter element 103 and then enters the third flow channel 1031 inside the filter element 103.

An outer wall surface of the support member body 1042 may be aligned with the outer wall surface of the inner shell 102, so that there is a water-pass gap between the support member body 1042 and the inner shell 102. The water body in the second flow channel 1014 continues to enter the water-pass gap, and enters the first water inlet 1042-3 of the water storage chamber 1041 from the water-pass gap. This is equivalent to that a water inlet path is extended. The water first entering the water storage chamber 1041 first flows out from the first water outlet 1042-4 of the water storage chamber 1041, which is beneficial to that the water first entering a water purification module is filtered first and then flows out from the water purification module, thereby preventing the retention of stale water.

Referring to FIG. 1 and FIG. 2, it may be further understood that the second end 1042-2 of the support member body 1042 is provided with a first block member 1044. The first block member 1044 is adapted to abut against the filter element 103, and is used to block an end of the filter element 103, so that the water in the water storage chamber 1041 is filtered by the filter element 103 and then enters the third flow channel 1031 inside the filter element 103. The first block member 1044 may be provided independently from the support member 104, which may be fixedly connected or detachably connected to the second end 1042-2 of the support member 104.

As shown in FIG. 2, the support member body 1042 and the first block member 1044 may also be integrally formed, so that a side of the first block member 1044 facing the filter element 103 is provided with a block groove 1044-1. The filter element 103 may be embedded in the block groove 1044-1, which is equivalent to that an outer wall surface of the filter element 103 and an inner side wall of the block groove 1044-1 are in interference fit to form a seal effect. A seal member may also be provided between the block groove 1044-1 and the filter element 103, so that the filter element 103 is connected with and at least partially seals the block groove 1044-1.

A protrusion is provided inside the block groove 1044-1. After the filter element 103 is embedded in the block groove 1044-1, the protrude portion 1044-2 extends into the third flow channel 1031, which makes the seal effect of the first block member 1044 better, and avoid the water leakage at an end portion of the filter element 103.

Referring to FIG. 1 and FIG. 2, it may be understood that the outer side wall of the support member body 1042 is provided with a limit portion 1042-5, and the inner shell 102 abuts against the limit portion 1042-5 to limit the inner shell 102 from continuing to move close the bottom wall of outer shell assembly 101, and play an axial support role for the inner shell 102.

A first water outlet 1042-4 is provided at a side wall between the limit portion 1042-5 and the second end 1042-2 of the support member body 1042, and the first water outlet 1042-4 is communicated with the second flow channel 1014. This is equivalent to that a water outlet direction is inclined toward the side wall of the support member body 1042, so that the water coming out from the water storage chamber 1041 flows into the second flow channel 1014 more smoothly.

Therefore, the support member 104 is not only suitable for axial support of the filter element 103, but also suitable for axial support of the inner shell 102, thereby reducing the number of components and parts of the water purification assembly 100, and further simplifying its structure.

Referring to FIG. 1, FIG. 2 and FIG. 3, it may be understood that the outer shell assembly 101 includes a first outer shell 1011 and a second outer shell 1012. The first outer shell 1011 and the second outer shell 1012 are detachably connected, that is, the first outer shell 1011 and the second outer shell 1012 may be in interference fit, may be clamped, or may be threadedly connected, etc., while ensuring the sealing between the first outer shell 1011 and the second outer shell 1012.

By detachably connecting the first outer shell 1011 and the second outer shell 1012, internal parts of the water purification assembly 100 may be replaced by disassembling the first outer shell 1011 and the second outer shell 1012, thus facilitating the maintenance and replacement of the water purification assembly 100.

Referring to FIG. 1, it may be understood that the radial distance of the first flow channel 1013 is greater than the radial distance of the second flow channel 1014, thereby ensuring a large water inlet and a small water outlet, so that the water storage chamber 1041 is in a state of dynamic balance.

Radial distances may be understood as a distance between an inner wall surface of the first outer shell 1011 and an outer wall surface of the inner shell 102, and a distance between the outer wall surface of the filter element 103 and the inner wall surface of the inner shell 102.

Referring to FIG. 1 and FIG. 2, it may be understood that in order to extend a flow path of the water body in the water purification assembly 100, a flow guide portion 1021 is provided between the inner shell 102 and the first outer shell 1011, and the flow guide portion 1021 may extend along a central axis of the inner shell 102 to form a spiral structure. The first flow channel 1013 is provided as a spiral flow channel, one end of the spiral flow channel is communicated with the main water inlet 1051, and another end of the spiral flow channel is communicated with the first water inlet 1042-3 of the water storage chamber 1041.

By providing the flow guide portion 1021 between the first outer shell 1011 and the inner shell 102, the first flow channel 1013 forms a spiral flow channel. When the water is input from the main water inlet 1051, the water flows to the water storage chamber 1041 along an extend direction of the spiral flow channel. This is equivalent to the spiral flow channel extending the flow path of the water body, so that the water body first flowing into the water purification assembly 100 first flows out of the water purification assembly 100, that is, first-in-first-out of the water body is realized, which can effectively prevent the accumulation of stale water, and prevent a phenomenon of water mixing from occurring.

Furthermore, by extending the flow path of the water body, a heat exchange area between the water body in the spiral flow channel and the outside is increased, thereby accelerating the cooling of the water body in the water purification assembly 100, so that the cooling effect of the water body is better. Meanwhile, the spiral flow channel can effectively prevent backflow along the spiral flow channel due to external factors during the water flow procedure.

Referring to FIG. 1 and FIG. 2, it may be further understood that the flow guide portion 1021 may be provided at the inner wall surface of the first outer shell 1011 or on the outer wall surface of the inner shell 102, or the flow guide portion 1021 may be sandwiched between the inner wall surface of the first outer shell 1011 and the outer wall surface of the inner shell 102.

That is, the flow guide portion 1021 is provided inside at least one of the first flow channel 1013 and the second flow channel 1014, which may be understood to mean that the flow guide portion 1021 is provided inside the first flow channel 1013 or the second flow channel 1014, or the flow guide portion 1021 may be provided inside both the first flow channel 1013 and the second flow channel 1014, and the flow guide portion 1021 extends along the central axis of the inner shell 102 to form a spiral structure.

An axial length of the flow guide portion 1021 extending relative to the central axis of the inner shell 102 is less than an axial length of the inner shell 102. For example, the axial length of the flow guide portion 1021 extending relative to the central axis of the inner shell 102 is equal to ½, ⅔, etc. of the axial length of the inner shell 102. This may also be understood as providing the flow guide portion 1021 at a part of the outer wall surface of the inner shell 102.

In order to further enhance an anti-mixing effect, the flow guide portion 1021 may be provided at the entire outer wall of the inner shell 102, that is, the axial length of the flow guide portion 1021 extending relative to the central axis of the inner shell 102 is equal to the axial length of the inner shell 102.

It should be noted that the filter element 103 may be an activated carbon rod filter element 103 or a filter element 103 rolled by a reverse osmosis membrane known in the art. Any purification core material that can achieve water filtration is available.

Referring to FIG. 1 to FIG. 5, it may be understood that the water purification assembly 100 further includes a socket assembly 105. The socket assembly 105 includes a socket main body and a valve core assembly 1056 provided inside the socket main body.

As shown in FIG. 3, FIG. 4 and FIG. 5, the socket main body is provided with a main water inlet 1051 and a main water outlet 1052. In addition, the socket main body is a hollow shell structure, and a bypass chamber 1053, a dispensing chamber 1054 and an operation chamber 1055 are provided inside the socket main body. The bypass chamber 1053 is communicated with the operation chamber 1055 through the dispensing chamber 1054. The socket assembly 105 is detachably connected to the water purification assembly 100 through the operation chamber 1055.

It should be noted that the main water inlet 1051 and the main water outlet 1052 do not limit a specific water flow direction. For example, the main water inlet 1051 may inlet or outlet water. Similarly, the main water outlet 1052 may outlet or inlet water. Specific arrangement may be selected based on actual use needs.

As shown in FIG. 4 and FIG. 5, it may be understood that the valve core assembly 1056 may be movably provided inside the dispensing chamber 1054, and is adapted to switch between a first position and a second position.

As shown in FIG. 4, in case that the valve core assembly 1056 is at the first position, the valve core assembly 1056 blocks the dispensing chamber 1054 and the operation chamber 1055, which is equivalent to that the dispensing chamber 1054 and the operation chamber 1055 are not communicated. The main water inlet 1051, the dispensing chamber 1054, the bypass chamber 1053 and the main water outlet 1052 are communicated with each other.

As shown in FIG. 5, in case that the valve core assembly 1056 is at the second position, the valve core assembly 1056 blocks the dispensing chamber 1054 and the bypass chamber 1053, which is equivalent to that the dispensing chamber 1054 and the bypass chamber 1053 are not communicated. The main water inlet 1051, the dispensing chamber 1054, the operation chamber 1055 and main water outlet 1052 are communicated with each other.

Referring to FIG. 4, it may be understood that the main water inlet 1051 may be communicated with an external water source through a water pipe, and the external water source may be tap water or well water, etc. The main water outlet 1052 is communicated with the water-use component 500 or the valve assembly 200 through a water pipe. The water-use component 500 may be a first ice maker 501, a second ice maker 502, a dispenser 503, etc. By controlling the position of the valve core assembly 1056 in the dispensing chamber 1054, the dispensing chamber 1054 is adjusted to be communicated with the bypass chamber 1053, then the main water inlet 1051 is communicated with the main water outlet 1052 through the dispensing chamber 1054 and the bypass chamber 1053, ensuring that the water path between the main water inlet 1051 and the main water outlet 1052 are communicated, to avoid water overflow when replacing the filter element 103.

Referring to FIG. 5, it may be understood that by controlling the position of the valve core assembly 1056 in the dispensing chamber 1054, the dispensing chamber 1054 and the operation chamber 1055 are adjusted to be communicated, so that the main water inlet 1051 is communicated with the main water outlet 1052 of the water purification assembly 100 through the dispensing chamber 1054 and the operation chamber 1055. Meanwhile, it is equivalent to that the water purification assembly 100 being in an operating state, that is, the external water source may enter from the main water inlet 1051, enter the water purification assembly 100 for filtering through the dispensing chamber 1054 and the operation chamber 1055, and flow out from the main water outlet 1052 after being filtered.

During usage, if the filter element 103 is to be replaced or repaired, as shown in FIG. 4, the water purification assembly 100 may be removed from the socket assembly 105. Meanwhile, the water purification assembly 100 is disconnected from the operation chamber 1055 of the socket assembly 105. In order to ensure the normal operation of the waterway system, the valve core assembly 1056 is moved to the first position, that is, the position shown in FIG. 4. The valve core assembly 1056 blocks the dispensing chamber 1054 and the operation chamber 1055, and the dispensing chamber 1054 and the bypass chamber 1053 are used to communicate the main water inlet 1051 with the main water outlet 1052. Therefore, the external water source enters the dispensing chamber 1054 through the main water inlet 1051, then enters the bypass chamber 1053 through the dispensing chamber 1054, and finally flows out from the main water outlet 1052. The water path between the main water inlet 1051 and the main water outlet 1052 is communicated, which prevents the water body form overflowing when replacing the filter element 103, thereby improving element replacement experience of the user.

When the water purification assembly 100 is assembled at the socket assembly 105, that is, the water purification assembly 100 is communicated with the operation chamber 1055 of the socket assembly 105, and the valve core assembly 1056 is moved to the second position, that is, the position shown in FIG. 5. The valve core assembly 1056 blocks the dispensing chamber 1054 and the bypass chamber 1053, and the dispensing chamber 1054 and the operation chamber 1055 are used to communicate the main water inlet 1051 with the main water outlet 1052. Therefore, the external water source enters the dispensing chamber 1054 through the main water inlet 1051, and then the water body enters the water purification assembly 100 through the operation chamber 1055 for filtering, and flows out from the main water outlet 1052 after being filtered.

In some embodiments of the present application, by providing the socket assembly 105 composed of the socket main body and the valve core assembly 1056 provided inside the socket main body at the water purification assembly 100, the bypass chamber 1053, the dispensing chamber 1054 and the operation chamber 1055 are provided inside the socket main body, and the bypass chamber 1053 is communicated with the operation chamber 1055 through the dispensing chamber 1054. The socket assembly is detachably connected to the water purification assembly 100 through the operation chamber 1055. The valve core assembly 1056 may be movably provided inside the dispensing chamber 1054, and may be switched between the first position and the second position. In case that the valve core assembly 1056 is at the first position, the valve core assembly 1056 blocks the dispensing chamber 1054 and the operation chamber 1055, and the dispensing chamber 1054 and the bypass chamber 1053 are used to communicate the main water inlet 1051 with the main water outlet 1052. During the replacing of the filter element 103, the waterway may be ensured to be smooth and would not affect the use of the user, thereby improving the user experience.

Referring to FIG. 4 and FIG. 5, it may be understood that the dispensing chamber 1054 includes a first dispensing chamber body 1054-1 and a second dispensing chamber body 1054-2 provided in parallel. The first dispensing chamber body 1054-1 is communicated with the main water inlet 1051, the second dispensing chamber body 1054-2 is communicated with the main water outlet 1052, one end of the bypass chamber 1053 is communicated with the operation chamber 1055 through the first dispensing chamber body 1054-1, and another end of the bypass chamber 1053 is communicated with the operation chamber 1055 through the second dispensing chamber body 1054-2.

In case that the valve core assembly 1056 moves to the first position, the valve core assembly 1056 may simultaneously block the first dispensing chamber body 1054-1 and the operation chamber 1055, as well as the second dispensing chamber body 1054-2 and the operation chamber 1055, thereby allowing the main water inlet 1051 communicate with the main water outlet 1052 through the first dispensing chamber body 1054-1, the bypass chamber 1053 and the second dispensing chamber body 1054-2.

In case that the valve core assembly 1056 moves to the second position, the valve core assembly 1056 may simultaneously block the first dispensing chamber body 1054-1 and the bypass chamber 1053, as well as the second dispensing chamber body 1054-2 and the bypass chamber 1053, so that the main water inlet 1051 is communicated with the main water outlet 1052 through the first dispensing chamber body 1054-1, the operation chamber 1055 and the second dispensing chamber body 1054-2.

Referring to FIG. 4 and FIG. 5, it may be understood that the valve core assembly 1056 includes a first eject rod 1056-1 and a second eject rod 1056-2. The first eject rod 1056-1 is movably provided inside the first dispensing chamber body 1054-1, and is used to control dispensing of the water body in the first dispensing chamber body 1054-1. The second eject rod 1056-2 is movably provided inside the second dispensing chamber body 1054-2, and is used to control dispensing of the water body in the second dispensing chamber body 1054-2.

At least part of the first eject rod 1056-1 and the second eject rod 1056-2 extends into the operation chamber 1055. Since the water purification assembly 100 is connected to the socket assembly 105 through the operation chamber 1055, that is, part of the water purification assembly 100 is provided inside the operation chamber 1055.

When the water purification assembly 100 is mounted at the socket assembly 105, the water purification assembly 100 extends into the operation chamber 1055, contacts with the first eject rod 1056-1 and the second eject rod 1056-2, and presses against the first eject rod 1056-1 and the second eject rod 1056-2 to achieve a squeeze effect, thereby causing position change of the first eject rod 1056-1 in the first dispensing chamber body 1054-1, and causing position change of the second eject rod 1056-2 in the second dispensing chamber body 1054-2 simultaneously, so that the first eject rod 1056-1 and the second eject rod 1056-2 move to the second position. The first eject rod 1056-1 blocks the first dispensing chamber 1054-1 and the bypass chamber 1053, and the second eject rod 1056-2 blocks the second dispensing chamber body 1054-2 and the bypass chamber 1053, so that the main water inlet 1051 communicates with the main water outlet 1052 through the first dispensing chamber body 1054-1, the operation chamber 1055 and the second dispensing chamber body 1054-2.

The first dispensing chamber body 1054-1 may be either a water inlet chamber or a water outlet chamber. Correspondingly, the second dispensing chamber body 1054-2 may be either a water outlet chamber or a water inlet chamber. Moreover, water inlet and outlet directions of the first dispensing chamber body 1054-1 and the second dispensing chamber body 1054-2 correspond to water inlet and outlet directions of the first flow channel 1013, the second flow channel 1014 and the third flow channel 1031.

Referring to FIG. 4 and FIG. 5, it may be understood that when the first dispensing chamber body 1054-1 is taken as the water inlet chamber and the second dispensing chamber body 1054-2 is taken as the water outlet chamber, the external water source enters the first dispensing chamber body 1054-1 through the main water inlet 1051, and enters the operation chamber 1055 through the first dispensing chamber body 1054-1. The water body then enters the water purification assembly 100 through the operation chamber 1055 for filtration. The filtered water body enters the second dispensing chamber body 1054-2 through the operation chamber 1055, and finally flows out from the main water outlet 1052.

It should be noted that both the first eject rod 1056-1 and the second eject rod 1056-2 can achieve a block effect between two adjacent chambers through a variable diameter design. For example, when the position of the first eject rod 1056-1 in the first dispensing chamber body 1054-1 changes, a diameter of the first eject rod 1056-1 near two ends is greater than a diameter at other positions, so that the first eject rod 1056-1 may block connect positions between the first dispensing chamber body 1054-1 and the bypass chamber 1053 and the operation chamber 1055, thereby blocking the first dispensing chamber body 1054-1 from communicating with the bypass chamber 1053, or blocking the first dispensing chamber body 1054-1 from communicating with the operation chamber 1055.

The second eject rod 1056-2 achieving a block effect between the second dispensing chamber body 1054-2 and the adjacent bypass chamber 1053 or the operation chamber 1055 through a variable diameter design, which is the same as the variable diameter design of the first eject rod 1056-1 mentioned above, and is not repeated here.

Referring to FIG. 4 and FIG. 5, it may be understood that the socket assembly 105 may further include a first clastic member 1056-3 and a second elastic member 1056-4. The first clastic member 1056-3 is sleeved at the first eject rod 1056-1, and an end of the first clastic member 1056-3 may be connected to the first eject rod 1056-1, and other two ends of the first elastic member 1056-3 may be connected to a wall surface of the first dispensing chamber body 1054-1.

During the mounting procedure, the first elastic member 1056-3 may be sleeved as a whole on an outer surface of the first eject rod 1056-1. A top end of the first elastic member 1056-3 may be connected to an inner wall surface of the first dispensing chamber body 1054-1, and a bottom end of the first elastic member 1056-3 may be connected to a step of the first eject rod 1056-1. The first elastic member 1056-3 may undergo elastic deformation or restore elastic deformation during the up and down movement of the first eject rod 1056-1.

The second elastic member 1056-4 is sleeved at the second eject rod 1056-2. An end of the second elastic member 1056-4 may be connected to the second eject rod 1056-2, and other two ends of the second elastic member 1056-4 may be connected to a wall surface of the second dispensing chamber body 1054-2.

During the mounting procedure, the second elastic member 1056-4 may be mounted in the same mode as the first elastic member 1056-3, that is, the second elastic member 1056-4 is sleeved at the second eject rod 1056-2 as a whole, and a top end of the second elastic member 1056-4 is connected to an inner wall surface of the second dispensing chamber body 1054-2, and a bottom end of the second elastic member 1056-4 is connected to a step of the second eject rod 1056-2.

The first elastic member 1056-3 and the second elastic member 1056-4 may both be springs, or other elastic elements that may be elastically deformed under an action of external force and may restore the clastic deformation by themselves.

As shown in FIG. 4, when the water purification assembly 100 is removed from the socket assembly 105, that is, the water purification assembly 100 is separated from the socket assembly 105, the water purification assembly 100 is disconnected from the operation chamber 1055, and the valve core component 1056 is located at the first position. The water purification assembly 100 is separated from the first eject rod 1056-1 and the second eject rod 1056-2 respectively, the first eject rod 1056-1 releases the squeeze effect on the first elastic member 1056-3, and the second eject rod 1056-2 releases the squeeze effect on the second clastic member 1056-4. Both the first elastic member 1056-3 and the second elastic member 1056-4 restore elastic deformation, that is, they are transformed from a compressed state to a free state.

The first elastic member 1056-3 drives the first eject rod 1056-1 to move toward a position of the operation chamber 1055, so that the first eject rod 1056-1 is stuck at a connection position between the first dispensing chamber body 1054-1 and the operation chamber 1055, and the water body flow path between the first dispensing chamber body 1054-1 and the operation chamber 1055 is blocked through the first eject rod 1056-1.

The first eject rod 1056-1 and the second eject rod 1056-2 both move toward the position where the bypass chamber 1053 is located. The first elastic member 1056-3 and the second elastic member 1056-4 are elastically deformed under pressure, that is, they are transformed from a free state to a compressed state.

The first eject rod 1056-1 is stuck at a connection position between the first dispensing chamber body 1054-1 and the bypass chamber 1053, and the water body flow path between the first dispensing chamber body 1054-1 and the bypass chamber 1053 is blocked through the first eject rod 1056-1. It is equivalent to that the first eject rod 1056-1 is away from a connection position between the first dispensing chamber body 1054-1 and the operation chamber 1055, and the block effect between the first dispensing chamber body 1054-1 and the operation chamber 1055 is released, so that the water body flow path between the first dispensing chamber body 1054-1 and the operation chamber 1055 is conducted.

Correspondingly, the second eject rod 1056-2 is stuck at a connection position between the second dispensing chamber body 1054-2 and the bypass chamber 1053, and the water body flow path between the second dispensing chamber body 1054-2 and the bypass chamber 1053 is blocked through the second eject rod 1056-2.

Referring to FIG. 2, it may be understood that the fixed seat 106 includes a first seat body 1061 and a second seat body 1062. The second seat body 1062 is connected to a side of the first seat body 1061, and the second seat body 1062 is provided with a position suitable for mounting the socket main body. The socket main body is connected to the fixed seat 106 through the second seat body 1062.

During usage, the fixed seat 106 may be fixed at an external device, the second seat body 1062 is connected to a front of the fixed seat 106, and a back of the fixed seat 106 is provided with bolt holes for connecting to the external device. To ensure the connect effect, the second seat body 1062 is provided with a pipe seat for clamping the main water inlet 1051, and a pipe seat for clamping the main water outlet 1052. The pipe seat for clamping the main water inlet 1051 is stuck at a pipe outer wall of the main water inlet 1051, and the pipe seat for clamping the main water outlet 1052 is stuck on a pipe outer wall of the main water outlet 1052, thereby ensuring the stability of the entire seat body.

It should be noted that the main water inlet 1051 may also be provided at the first outer shell 1011, and the main water outlet 1052 may be provided at the inner shell 102. That is, the main water inlet 1051 is provided at an end of the first outer shell 1011, and the main water inlet 1051 is communicated with the first flow channel 1013. Meanwhile, the main water outlet 1052 is provided at an end of the inner shell 102, and the main water outlet 1052 is communicated with the third flow channel 1031.

Referring to FIG. 1, FIG. 2, FIG. 6 and FIG. 7, it may be understood that in order to prevent the water inside the water purification assembly 100 from flowing out when the filter element 103 is pulled out or replaced, the water purification assembly 100 may also include a water-stop assembly 107. A water-stop chamber 1011-2 is provided inside the first outer shell 1011 and located at a water outlet side of the filter element 103.

The check valve 1073 may not only be used to limit a flow direction of the water body, but also may realize the conducting-blocking of a waterway according to the pressure difference on both sides of the check valve 1073.

As shown in FIG. 6, when the water-stop assembly 107 is at the first position, the water-stop assembly 107 may block the first passage 1074. The check valve 1073 determines that the pressure difference on both sides is small and blocks the waterway, that is, the check valve 1073 blocks the second passage 1075.

The water-stop assembly 107 is detachably connected to the socket assembly 105. When it is determined that the filter element 103 is to be pulled out or replaced, the water purification assembly 100 is removed from the socket assembly 105. The water-stop assembly 107 moves to an outside of the first outer shell 1011 to abut against the inner wall of the first outer shell 1011, that is, the water-stop assembly 107 abuts against the chamber wall of the water-stop chamber 1011-2, thereby blocking the first passage 1074, and the water body cannot flow through the first passage 1074.
