Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and in particular to a water supply system and refrigeration equipment for use in refrigeration equipment. Background Technology

[0002] In related technologies, the water supply system of refrigeration equipment supplies a portion of the water purified by water purification components to the ice maker, while the other portion of the water is stored in a water tank and then supplied from the water tank to the distributor for user use.

[0003] Because components such as water tanks, ice makers, and distributors are installed in relatively dispersed locations within refrigeration equipment, the connection pipelines of the water supply system are quite complex, and the flow path of the water supply system is too long, making it inconvenient to maintain and replace the water supply system. Summary of the Invention

[0004] This application aims to at least solve one of the technical problems existing in the related art. To this end, this application provides a water supply system for refrigeration equipment, which integrates the water supply system and centrally arranges the various components to simplify the design of the water supply pipeline, shorten the water supply path, facilitate the maintenance and replacement of water supply system parts, and improve the reliability of the water supply system.

[0068] See details Figure 8 and Figure 9 The water supply system for the refrigeration equipment 600 provided in this application embodiment includes a water purification component 100, a first water path 300, and a second water path 400.

[0069] The first water path 300 can be used to connect an external water source to the inlet of the water purification component 100 to supply water to the water purification component 100; the second water path 400 is connected to the outlet of the water purification component 100 and can selectively supply water from the water purification component 100 to the water-using device 500.

[0070] See details Figure 8 and Figure 9 It is understandable that there can be one or more water-using devices 500. The number of water-using devices 500 installed depends on the different user needs.

[0071] When the water-using device 500 is a single unit, the water supply system for the refrigeration equipment includes a water purification component 100, a first water path 300, and a second water path 400.

[0072] The first water path 300 can be used to connect an external water source to the inlet of the water purification component 100 to supply water to the water purification component 100; the second water path 400 is connected to the outlet of the water purification component 100 and can directly supply water from the water purification component 100 to the water-using device 500.

[0073] When there are multiple water-using devices 500, for example, the water-using devices (500) include an ice maker and a distributor (503), the water supply system for the refrigeration equipment includes a water purification component 100, a first water path 300, a valve component 200, and a second water path 400.

[0074] The first water path 300 can be used to connect an external water source to the inlet of the water purification component 100 to supply water to the water purification component 100; the inlet of the valve assembly 200 is connected to the outlet of the water purification component 100 to distribute the water filtered by the water purification component 100; the second water path 400 is connected to the outlet of the valve assembly 200 to selectively supply water from the water purification component 100 to the water-using device 500.

[0075] like Figure 9 As shown, it can be understood that the second water circuit 400 includes a first water supply pipe assembly and a second water supply pipe 403. The first water supply pipe assembly is used to connect the valve assembly 200 to the ice maker unit and deliver the water distributed by the valve assembly 200 to the ice maker unit. The second water supply pipe 403 is used to connect the valve assembly 200 to the distributor 503 and deliver the water distributed by the valve assembly 200 to the distributor 503.

[0076] like Figure 9 As shown, it can be understood that the ice-making unit includes a first ice maker 501 and a second ice maker 502; the first water supply pipe assembly includes a first sub-water supply pipe 401 and a second sub-water supply pipe 402, the first sub-water supply pipe 401 is used to connect the valve assembly 200 to the first ice maker 501, and the second sub-water supply pipe 402 is used to connect the valve assembly 200 to the second ice maker 502.

[0077] The water supply system for refrigeration equipment 600 provided in this application embodiment makes the components of the water system highly concentrated. Compared with the water supply system of related technologies, it reduces the connection points between pipes, reduces the risk of water leakage caused by loose joints, and shortens the length of the water supply system, making it easier to replace and maintain the water system.

[0078] By improving the water purification component 100, the water system is simplified. Replacing the water purification component 100 completes the replacement of the water storage space in the entire water system, further ensuring the safety of users' water use.

[0079] See details Figure 1 It is understood that the water purification component 100 includes an outer shell component 101, a filter element 103, an inner shell 102, and a support member 104. The outer shell component 101 has an internal cavity, and the filter element 103 is disposed in the cavity. The inner shell 102 is disposed between the outer shell component 101 and the filter element 103, and a first flow channel 1013 for water flow is constructed between the inner shell 102 and the outer shell component 101. A second flow channel 1014 for water flow is constructed between the inner shell 102 and the filter element 103.

[0080] The support member 104 is mainly used for axial support of the filter element 103, so that there is a certain space between the filter element 103 and the bottom wall of the outer shell assembly 101. That is, a water storage cavity 1041 is constructed between the filter element 103 and the bottom wall of the outer shell assembly 101. The water storage cavity 1041 is connected to the first flow channel 1013 and the second flow channel 1014 respectively. A third flow channel 1031 is constructed inside the filter element 103, which means that the filter element 103 is located between the second flow channel 1014 and the third flow channel 1031.

[0081] The first flow channel 1013 can be either an inlet or outlet flow channel, the second flow channel 1014 can be either an inlet or outlet flow channel, and the third flow channel 1031 can also be either an inlet or outlet flow channel.

[0082] When the first flow channel 1013 and the second flow channel 1014 are both inlet flow channels, and the third flow channel 1031 is an outlet flow channel, the first flow channel 1013 can be connected to the main inlet 1051 of the water purification component 100, and the third flow channel 1031 can be connected to the main outlet 1052 of the water purification component 100.

[0083] During operation, the water purification component 100 connects to an external water source through its main inlet 1051. Water flows from the main inlet 1051 into the first flow channel 1013 and then into the storage chamber 1041 for storage. When the user needs to use the purified water, the water stored in the storage chamber 1041 first flows from the storage chamber 1041 into the second flow channel 1014, then through the filter element 103 into the third flow channel 1031, and finally out through the third flow channel 1031 to the main outlet 1052.

[0084] This can be understood as follows: by incorporating a water storage chamber 1041 and internal water channels within the water purification component 100, the integration level of the water purification component 100 is increased, thus enabling it to not only have purification functions but also water storage functions. This replaces the independent water tank structure found in related technologies, eliminating the water tank and simplifying the structural design, reducing the space occupied. Furthermore, the elimination of connecting pipes and joints between the water tank and the water purification component 100 effectively avoids the risk of structural leakage, resulting in improved product reliability.

[0085] See Figure 1It is understood that the support member 104 can be confined to the inner wall surface of the outer casing assembly 101, and the water storage cavity 1041 is formed inside the support member 104. This is equivalent to the support member 104 being snapped or overlapped on the inner wall surface of the outer casing assembly 101 to prevent the filter element 103 from continuing to extend into the bottom wall of the outer casing assembly 101, thereby creating a certain space between the bottom wall of the outer casing assembly 101 and the support member 104, thus forming the water storage cavity 1041.

[0086] After water enters the water storage chamber 1041 through the first flow channel 1013, the water can be temporarily stored in the water storage chamber 1041, which is equivalent to a water tank for storing water. Part of the water in the water storage chamber 1041 enters the second flow channel 1014, and then permeates from the second flow channel 1014 into the filter element 103 for filtration. The water filtered by the filter element 103 flows out from the third flow channel 1031 inside the filter element 103.

[0087] By integrating a water storage chamber 1041 into the water purification component 100 to store water, the structure of a water tank is eliminated, as are the connecting pipes and joints between the water tank and the water purification component 100. This simplifies the structure, reduces the space occupied, and effectively avoids the risk of leakage. Furthermore, during water purification, the integrated water storage chamber 1041 allows the input side of the filter element 103 to be fully immersed in the water environment, ensuring better purification performance.

[0088] See Figure 1 It can be further understood that the structural shape of the support member 104 is adapted to the structural shape of the filter element 103 and the inner shell 102. When both the inner shell 102 and the filter element 103 are cylindrical structures, the support member 104 can also be a cylindrical structure. The support member 104 is fixedly installed on the inner wall surface of the inner shell 102. One side of the support member 104 can abut against the filter element 103 to block one end of the filter element 103. The other side of the support member 104 can form a space for storing water, namely the water storage cavity 1041, together with part of the inner wall surface of the outer shell assembly 101 and the bottom wall of the outer shell assembly 101.

[0089] Meanwhile, a stop (not shown in the figure) can be provided on the inner wall surface of the outer shell assembly 101 to limit the axial support of the inner shell 102, so that the end face of one end of the inner shell 102 is flush with the surface of the support member 104 facing the water storage chamber 1041, allowing the water passing through the first flow channel 1013 to directly enter the water storage chamber 1041 for storage. Furthermore, multiple first water outlets 1042-4 are provided on the support member 104, each of which is connected to the second flow channel 1014, allowing water from the water storage chamber 1041 to enter the second flow channel 1014 through the first water outlet 1042-4.

[0090] See Figure 1 In a broader sense, the inner shell 102 can extend to the bottom wall of the outer shell assembly 101, creating a certain water-passing gap between it and the inner wall of the outer shell assembly 101. This effectively separates the water storage chamber 1041 from the first flow channel 1013, allowing water from the second flow channel 1014 to continue entering through this water-passing gap and then into the water storage chamber 1041. This effectively extends the water inlet path, ensuring that the water that first enters the water storage chamber 1041 flows out first from the first outlet 1042-4 of the water storage chamber 1041. This facilitates the filtration of water that first enters the water quality purification module before it flows out, preventing the retention of stagnant water.

[0091] An opening can be made at the bottom end of the inner shell 102 near the outer shell assembly 101, that is, multiple openings can be made on the side wall or end face of the inner shell 102 to form the first water inlet 1042-3 of the water storage cavity 1041.

[0092] See Figure 2 It is understandable that the structural shape of the support member 104 is adapted to the structural shape of the filter element 103 and the inner shell 102, etc., and can be a cylindrical structure, used to axially support the filter element 103 and seal one end of the filter element 103. The interior of the support member 104 is a hollow structure to form a water flow channel and a water storage space.

[0093] The support 104 includes a support body 1042 and a limiting block 1043. The limiting block 1043 is disposed on the outer side wall of the support body 1042 and is equivalent to the connecting lug of the support body 1042. It is suitable for abutting or overlapping with the inner wall surface of the outer shell assembly 101 to fix the support body 1042.

[0094] The support body 1042 has a first end 1042-1 and a second end 1042-2. The first end 1042-1 has a first inlet 1042-3, which communicates with the first flow channel 1013 so that water from the first flow channel 1013 enters the water storage chamber 1041 through the first inlet 1042-3. The second end 1042-2 is adapted to abut against the filter element 103 to block one end of the filter element 103 so that water in the water storage chamber 1041 enters the third flow channel 1031 inside the filter element 103 after being filtered by the filter element 103.

[0095] The outer wall of the support body 1042 can be aligned with the outer wall of the inner shell 102, creating a water passage gap between them. This allows water from the second flow channel 1014 to continue entering this gap and then flowing into the first inlet 1042-3 of the water storage chamber 1041. This effectively extends the water inlet path, ensuring that the water that first enters the water storage chamber 1041 flows out first from the first outlet 1042-4. This facilitates the filtration of water that first enters the water quality purification module before it flows out, preventing the retention of stagnant water.

[0096] See Figure 1 and Figure 2 It can be further understood that the second end 1042-2 of the support body 1042 is provided with a first sealing member 1044. The first sealing member 1044 is adapted to abut against the filter element 103 and is used to block one end of the filter element 103 so that the water in the water storage chamber 1041 enters the third flow channel 1031 inside the filter element 103 after being filtered by the filter element 103. The first sealing member 1044 can be set independently from the support 104, and it can be fixedly connected or detachably connected to the second end 1042-2 of the support 104.

[0097] like Figure 2 As shown, the support body 1042 and the first sealing member 1044 can also be integrally formed, so that the first sealing member 1044 has a sealing groove 1044-1 on the side facing the filter element 103. The filter element 103 can be embedded in the sealing groove 1044-1, which is equivalent to the outer wall surface of the filter element 103 and the inner side wall of the sealing groove 1044-1 being press-fitted to form a sealing effect. Alternatively, a sealing member can be provided between the sealing groove 1044-1 and the filter element 103 to make the filter element 103 and the sealing groove 1044-1 sealed together.

[0098] A protrusion is provided in the sealing groove 1044-1. After the filter element 103 is embedded in the sealing groove 1044-1, the protrusion 1044-2 extends into the third flow channel 1031, which can make the sealing effect of the first sealing member 1044 better and avoid water leakage at the end of the filter element 103.

[0099] See Figure 1 and Figure 2 It is understandable that the outer wall of the support body 1042 is provided with a limiting part 1042-5, and the inner shell 102 abuts against the limiting part 1042-5 to limit the inner shell 102 from continuing to approach the bottom wall of the outer shell assembly 101, thereby providing axial support for the inner shell 102.

[0100] A first water outlet 1042-4 is provided on the side wall between the limiting part 1042-5 and the second end 1042-2 of the support body 1042. The first water outlet 1042-4 is connected to the second flow channel 1014, which means that the water outlet direction is oblique to the side wall of the support body 1042, so that the water coming out of the water storage chamber 1041 flows more smoothly into the second flow channel 1014.

[0101] Therefore, the support member 104 is suitable not only for axial support of the filter element 103, but also for axial support of the inner shell 102, thereby reducing the number of parts in the water purification assembly 100 and further simplifying its structure.

[0102] See Figure 1 , Figure 2 and Figure 3 It is understood that the housing assembly 101 includes a first housing 1011 and a second housing 1012. The first housing 1011 and the second housing 1012 are detachably connected, that is, the first housing 1011 and the second housing 1012 can be interference-fitted, snap-fitted or threaded, etc., while ensuring the sealing between the first housing 1011 and the second housing 1012.

[0103] By detachably connecting the first housing 1011 and the second housing 1012, the internal components of the water purification component 100 can be replaced by disassembling the first housing 1011 and the second housing 1012, thereby facilitating the maintenance and replacement of the water purification component 100.

[0104] See Figure 1 It is understandable that the radial spacing of the first flow channel 1013 is greater than the radial spacing of the second flow channel 1014, thereby ensuring a large inflow and a small outflow, so that the water storage chamber 1041 is in a state of dynamic equilibrium.

[0105] The radial spacing can be understood as the distance between the inner wall surface of the first outer shell 1011 and the outer wall surface of the inner shell 102, and the distance between the outer wall surface of the filter element 103 and the inner wall surface of the inner shell 102.

[0106] See Figure 1 and Figure 2 Understandably, in order to extend the flow path of water in the water purification component 100, a flow guide 1021 is provided between the inner shell 102 and the first outer shell 1011. This flow guide 1021 can extend along the central axis of the inner shell 102 to form a spiral structure. The first flow channel 1013 is constructed as a spiral flow channel, with one end connected to the main inlet 1051 and the other end connected to the first inlet 1042-3 of the water storage chamber 1041.

[0107] By providing a guide section 1021 between the first outer shell 1011 and the inner shell 102, the first flow channel 1013 forms a spiral flow channel. When water is input from the main inlet 1051, it flows towards the water storage chamber 1041 along the extension direction of the spiral flow channel. This is equivalent to the spiral flow channel extending the flow path of the water, so that the water that first enters the water purification component 100 flows out of the water purification component 100 first, thus achieving first-in-first-out water flow, effectively preventing the accumulation of stagnant water and preventing water mixing.

[0108] Furthermore, by extending the water flow path, the heat exchange area between the water inside the spiral flow channel and the outside is increased, thereby accelerating the cooling of the water inside the water purification component 100 and improving the cooling effect. At the same time, the spiral flow channel can effectively prevent backflow caused by external factors during water flow.

[0109] See Figure 1 and Figure 2 It can be further understood that the flow guide 1021 can be disposed on 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 1021 can be sandwiched between the inner wall surface of the first outer shell 1011 and the outer wall surface of the inner shell 102.

[0110] That is, at least one of the first flow channel 1013 and the second flow channel 1014 is provided with a flow guide 1021. This can be understood as the flow guide 1021 being provided in either the first flow channel 1013 or the second flow channel 1014, or the flow guide 1021 being provided in both the first flow channel 1013 and the second flow channel 1014. The flow guide 1021 extends along the central axis of the inner shell 102 to form a spiral structure.

[0111] The axial length of the flow guide 1021 extending relative to the central axis of the inner shell 102 is less than the axial length of the inner shell 102. For example, the axial length of the flow guide 1021 extending relative to the central axis of the inner shell 102 is equal to one-half or two-thirds of the axial length of the inner shell 102. It can also be understood that the flow guide 1021 is provided on part of the outer wall surface of the inner shell 102.

[0112] To further enhance the anti-mixing effect, the flow guide 1021 can be provided on the entire outer wall of the inner shell 102, that is, the axial length of the flow guide 1021 extending relative to the central axis of the inner shell 102 is equal to the axial length of the inner shell 102.

[0113] It should be noted that the filter element 103 can be an activated carbon rod filter element 103 or a filter element 103 made of reverse osmosis membrane that is known in the art. Any purification core material that can achieve water filtration is acceptable.

[0114] See Figures 1 to 5It is understood that the water purification component 100 also includes a connector component 105, which includes a connector body and a valve core component 1056 disposed therein.

[0115] like Figure 3 , Figure 4 and Figure 5 As shown, the main body of the connector is provided with a main inlet 1051 and a main outlet 1052. In addition, the main body of the connector is a hollow shell structure, and its internal structure includes a bypass cavity 1053, a distribution cavity 1054 and a working cavity 1055. The bypass cavity 1053 is connected to the working cavity 1055 through the distribution cavity 1054. The connector assembly is detachably connected to the water purification assembly 100 through the working cavity 1055.

[0116] It should be noted that the main inlet 1051 and the main outlet 1052 do not limit the specific direction of water flow. For example, the main inlet 1051 can be used for both water intake and water discharge; similarly, the main outlet 1052 can be used for both water intake and water discharge. The specific settings are selected according to actual usage needs.

[0117] like Figure 4 and Figure 5 As shown, it can be understood that the valve core assembly 1056 can be movably disposed in the distribution chamber 1054 and is adapted to switch between a first position and a second position.

[0118] like Figure 4 As shown, when the valve core assembly 1056 is in the first position, the valve core assembly 1056 blocks the distribution chamber 1054 from the working chamber 1055, which is equivalent to the distribution chamber 1054 and the working chamber 1055 not being connected. The main inlet 1051, the distribution chamber 1054, the bypass chamber 1053 and the main outlet 1052 are interconnected.

[0119] like Figure 5 As shown, when the valve core assembly 1056 is in the second position, the valve core assembly 1056 blocks the distribution chamber 1054 and the bypass chamber 1053, which is equivalent to the distribution chamber 1054 and the bypass chamber 1053 not being connected, and the main inlet 1051, the distribution chamber 1054, the working chamber 1055 and the main outlet 1052 are interconnected.

[0120] See Figure 4It is understandable that the main inlet 1051 can be connected to an external water source via a water pipe, such as tap water or well water. The main outlet 1052 is connected to a water-using device 500 or a valve assembly 200 via a water pipe. The water-using device 500 can be a first ice maker 501, a second ice maker 502, or a distributor 503, etc. By controlling the position of the valve core assembly 1056 in the distribution chamber 1054, the distribution chamber 1054 and the bypass chamber 1053 are adjusted to be connected, so that the main inlet 1051 is connected to the main outlet 1052 through the distribution chamber 1054 and the bypass chamber 1053, ensuring that the water path between the main inlet 1051 and the main outlet 1052 is connected and preventing water overflow when replacing the filter element 103.

[0121] See Figure 5 It is understandable that by controlling the position of the valve core assembly 1056 in the distribution chamber 1054, the distribution chamber 1054 and the working chamber 1055 are adjusted to be connected, so that the main inlet 1051 is connected to the main outlet 1052 of the water purification component 100 through the distribution chamber 1054 and the working chamber 1055. At this time, it is equivalent to the water purification component 100 being in working state, that is, the external water source can enter from the main inlet 1051, pass through the distribution chamber 1054 and the working chamber 1055 in sequence, enter the water purification component 100 for filtration, and then flow out from the main outlet 1052.

[0122] If filter element 103 needs to be replaced or repaired during use, such as Figure 4 As shown, the water purification component 100 can be detached from the connector assembly 105. At this time, the water purification component 100 is disconnected from the working chamber 1055 of the connector assembly 105. To ensure the normal operation of the water system, the valve core assembly 1056 is moved to the first position, i.e. Figure 4 As shown, the valve core assembly 1056 blocks the distribution chamber 1054 and the working chamber 1055, and connects the main inlet 1051 and the main outlet 1052 through the distribution chamber 1054 and the bypass chamber 1053. Thus, external water enters the distribution chamber 1054 through the main inlet 1051, then enters the bypass chamber 1053 from the distribution chamber 1054, and finally flows out from the main outlet 1052. The water path between the main inlet 1051 and the main outlet 1052 is connected, preventing water overflow when replacing the filter element 103, thereby improving the user's filter replacement experience.

[0123] When the water purification component 100 is assembled on the receiving assembly 105, that is, when the water purification component 100 is connected to the working chamber 1055 of the receiving assembly 105, the valve core assembly 1056 is moved to the second position, such as... Figure 5As shown, the valve core assembly 1056 blocks the distribution chamber 1054 and the bypass chamber 1053, and connects the main inlet 1051 and the main outlet 1052 via the distribution chamber 1054 and the working chamber 1055. Thus, external water enters the distribution chamber 1054 through the main inlet 1051, then passes through the working chamber 1055 into the water purification assembly 100 for filtration, and finally flows out through the main outlet 1052.

[0124] This embodiment of the application provides a receiving assembly 105 on the water purification component 100, consisting of a receiving body and a valve core assembly 1056 disposed therein. The receiving body contains a bypass cavity 1053, a distribution cavity 1054, and a working cavity 1055, with the bypass cavity 1053 communicating with the working cavity 1055 via the distribution cavity 1054. The receiving assembly is detachably connected to the water purification component 100 via the working cavity 1055. The valve core assembly 1056 is movably disposed in the distribution cavity 1054 and can switch between a first position and a second position. In the first position, the valve core assembly 1056 blocks the distribution cavity 1054 and the working cavity 1055, connecting the main inlet 1051 and the main outlet 1052 via the distribution cavity 1054 and the bypass cavity 1053. This ensures unobstructed water flow during filter element 103 replacement, without affecting user operation and improving user experience.

[0125] See Figure 4 and Figure 5 It is understood that the distribution chamber 1054 includes a first distribution chamber 1054-1 and a second distribution chamber 1054-2 arranged in parallel. The first distribution chamber 1054-1 is connected to the main inlet 1051, and the second distribution chamber 1054-2 is connected to the main outlet 1052. One end of the bypass chamber 1053 is connected to the working chamber 1055 through the first distribution chamber 1054-1, and the other end of the bypass chamber 1053 is connected to the working chamber 1055 through the second distribution chamber 1054-2.

[0126] When the valve core assembly 1056 moves to the first position, the valve core assembly 1056 can simultaneously block the first distribution chamber 1054-1 and the working chamber 1055, as well as the second distribution chamber 1054-2 and the working chamber 1055, so that the main inlet 1051 is connected to the main outlet 1052 through the first distribution chamber 1054-1, the bypass chamber 1053 and the second distribution chamber 1054-2.

[0127] When the valve core assembly 1056 moves to the second position, the valve core assembly 1056 can simultaneously block the first distribution chamber 1054-1 and the bypass chamber 1053, as well as the second distribution chamber 1054-2 and the bypass chamber 1053, so that the main inlet 1051 is connected to the main outlet 1052 through the first distribution chamber 1054-1, the working chamber 1055 and the second distribution chamber 1054-2.

[0128] See Figure 4 and Figure 5 It is understood that the valve core assembly 1056 includes a first push rod 1056-1 and a second push rod 1056-2. The first push rod 1056-1 is movably disposed in the first distribution chamber 1054-1 for controlling the water distribution in the first distribution chamber 1054-1. The second push rod 1056-2 is movably disposed in the second distribution chamber 1054-2 for controlling the water distribution in the second distribution chamber 1054-2.

[0129] Among them, at least a portion of the first push rod 1056-1 and the second push rod 1056-2 extends into the working chamber 1055. Since the water purification component 100 is connected to the receiving component 105 through the working chamber 1055, that is, the water purification component 100 is partially disposed in the working chamber 1055.

[0130] When the water purification component 100 is installed on the receiving assembly 105, the water purification component 100 extends into the working chamber 1055, contacts the first push rod 1056-1 and the second push rod 1056-2, and exerts a squeezing effect on the first push rod 1056-1 and the second push rod 1056-2, thereby changing the position of the first push rod 1056-1 in the first distribution cavity 1054-1, and simultaneously changing the position of the second push rod 1056-2 in the second distribution cavity 1054-2. The position changes so that the first push rod 1056-1 and the second push rod 1056-2 move to the second position. The first push rod 1056-1 blocks the first distribution cavity 1054-1 and the bypass cavity 1053, and the second push rod 1056-2 blocks the second distribution cavity 1054-2 and the bypass cavity 1053, so that the main inlet 1051 is connected to the main outlet 1052 through the first distribution cavity 1054-1, the working cavity 1055 and the second distribution cavity 1054-2.

[0131] The first distribution chamber 1054-1 can be either an inlet chamber or an outlet chamber. Similarly, the second distribution chamber 1054-2 can be either an outlet chamber or an inlet chamber. Furthermore, the inlet and outlet directions of the first and second distribution chambers 1054-1 and 1054-2 correspond to the inlet and outlet directions of the first flow channel 1013, the second flow channel 1014, and the third flow channel 1031.

[0132] See Figure 4 and Figure 5 It is understandable that when the first distribution chamber 1054-1 is used as the water inlet chamber and the second distribution chamber 1054-2 is used as the water outlet chamber, the external water source enters the first distribution chamber 1054-1 through the main water inlet 1051, and then enters the working chamber 1055 through the first distribution chamber 1054-1. The water then enters the water purification component 100 through the working chamber 1055 for filtration. The filtered water then enters the second distribution chamber 1054-2 through the working chamber 1055, and finally flows out from the main water outlet 1052.

[0133] It should be noted that both the first push rod 1056-1 and the second push rod 1056-2 can achieve the blocking effect between adjacent cavities through a variable diameter design. For example, when the position of the first push rod 1056-1 in the first distribution cavity 1054-1 changes, the diameter of the first push rod 1056-1 near both ends is larger than the diameter at other positions, so that the first push rod 1056-1 can block the connection position between the first distribution cavity 1054-1 and the bypass cavity 1053 and the working cavity 1055, thereby blocking the communication between the first distribution cavity 1054-1 and the bypass cavity 1053, or blocking the communication between the first distribution cavity 1054-1 and the working cavity 1055.

[0134] The second push rod 1056-2, through a variable diameter design, achieves the blocking effect between the second distribution cavity 1054-2 and the adjacent bypass cavity 1053 or working cavity 1055, which is the same as the variable diameter design of the first push rod 1056-1 mentioned above, and will not be repeated here.

[0135] See Figure 4 and Figure 5 It is understood that the receiving assembly 105 may also include a first elastic element 1056-3 and a second elastic element 1056-4. The first elastic element 1056-3 is sleeved on the first push rod 1056-1, and one end of the first elastic element 1056-3 can be connected to the first push rod 1056-1, and the other two ends of the first elastic element 1056-3 can be connected to the wall of the first distribution cavity 1054-1.

[0136] During installation, the first elastic element 1056-3 can be integrally fitted onto the outer surface of the first push rod 1056-1. The top end of the first elastic element 1056-3 can be connected to the inner wall of the first distribution cavity 1054-1, and the bottom end of the first elastic element 1056-3 can be connected to the step of the first push rod 1056-1. This allows the first elastic element 1056-3 to undergo elastic deformation or recover its elastic deformation during the up-and-down movement of the first push rod 1056-1.

[0137] The second elastic element 1056-4 is sleeved on the second push rod 1056-2. One end of the second elastic element 1056-4 can be connected to the second push rod 1056-2, and the other two ends of the second elastic element 1056-4 can be connected to the wall of the second distribution cavity 1054-2.

[0138] During installation, the second elastic element 1056-4 can be installed in the same way as the first elastic element 1056-3. That is, the second elastic element 1056-4 is entirely sleeved on the second push rod 1056-2, with its top end connected to the inner wall of the second distribution cavity 1054-2 and its bottom end connected to the step of the second push rod 1056-2.

[0139] The first elastic element 1056-3 and the second elastic element 1056-4 can both be springs or other elastic elements that can undergo elastic deformation under external force and recover their elastic deformation on their own.

[0140] like Figure 4 As shown, when the water purification component 100 is detached from the connector assembly 105, that is, when the water purification component 100 is separated from the connector assembly 105 and the water purification component 100 is disconnected from the working chamber 1055, the valve core assembly 1056 is in the first position at this time, and the water purification component 100 is disengaged from the first push rod 1056-1 and the second push rod 1056-2 respectively. The first push rod 1056-1 releases the squeezing action on the first elastic element 1056-3, and the second push rod 1056-2 releases the squeezing action on the second elastic element 1056-4. The first elastic element 1056-3 and the second elastic element 1056-4 both recover their elastic deformation, that is, they change from the compressed state to the free state.

[0141] At this time, the first elastic element 1056-3 drives the first push rod 1056-1 to move towards the position of the working chamber 1055, so that the first push rod 1056-1 is locked at the connection between the first distribution chamber 1054-1 and the working chamber 1055, blocking the water flow path between the first distribution chamber 1054-1 and the working chamber 1055. At the same time, it is equivalent to the first push rod 1056-1 moving away from the connection between the first distribution chamber 1054-1 and the bypass chamber 1053, releasing the blocking effect between the first distribution chamber 1054-1 and the bypass chamber 1053, and opening the water flow path between the first distribution chamber 1054-1 and the bypass chamber 1053.

[0142] Correspondingly, the second elastic element 1056-4 drives the second push rod 1056-2 to move towards the position of the working chamber 1055, so that the second push rod 1056-2 is locked at the connection between the second distribution chamber 1054-2 and the working chamber 1055. The second push rod 1056-2 blocks the water flow path between the second distribution chamber 1054-2 and the working chamber 1055. At the same time, it is equivalent to the second push rod 1056-2 moving away from the connection between the second distribution chamber 1054-2 and the bypass chamber 1053. The second push rod 1056-2 releases the blocking effect between the second distribution chamber 1054-2 and the bypass chamber 1053, so that the water flow path between the second distribution chamber 1054-2 and the bypass chamber 1053 is open.

[0143] like Figure 5 As shown, when the water purification component 100 is installed on the connector component 105, that is, when the water purification component 100 is connected in the working chamber 1055, the valve core component 1056 is in the second position, and the water purification component 100 exerts a squeezing effect on the first push rod 1056-1 and the second push rod 1056-2. The first push rod 1056-1 and the second push rod 1056-2 both move towards the position of the bypass chamber 1053. At this time, the first elastic element 1056-3 and the second elastic element 1056-4 are compressed and undergo elastic deformation, that is, they change from a free state to a compressed state.

[0144] At this time, the first push rod 1056-1 is engaged at the connection between the first distribution cavity 1054-1 and the bypass cavity 1053, blocking the water flow path between the first distribution cavity 1054-1 and the bypass cavity 1053. Simultaneously, this is equivalent to the first push rod 1056-1 moving away from the connection between the first distribution cavity 1054-1 and the working cavity 1055, releasing the blocking effect between the first distribution cavity 1054-1 and the working cavity 1055, and allowing the water flow path between the first distribution cavity 1054-1 and the working cavity 1055 to open.

[0145] Correspondingly, the second push rod 1056-2 is engaged at the connection between the second distribution cavity 1054-2 and the bypass cavity 1053. The second push rod 1056-2 blocks the water flow path between the second distribution cavity 1054-2 and the bypass cavity 1053. At the same time, it is equivalent to the second push rod 1056-2 moving away from the connection between the second distribution cavity 1054-2 and the working cavity 1055, releasing the blocking effect between the second distribution cavity 1054-2 and the working cavity 1055, and opening the water flow path between the second distribution cavity 1054-2 and the working cavity 1055.

[0146] See Figure 4 and Figure 5To ensure that the valve core assembly 1056 has a good blocking effect, the seat assembly 105 also includes a fourth sealing ring 1057 and a fifth sealing ring 1058. At least one fourth sealing ring 1057 is fitted on the first push rod 1056-1 near the working chamber 1055, and at least one fourth sealing ring 1057 is fitted on the second push rod 1056-2 near the working chamber 1055.

[0147] At least one fifth sealing ring 1058 is fitted on the first push rod 1056-1 near the bypass cavity 1053, and at least one fifth sealing ring 1058 is fitted on the second push rod 1056-2 near the bypass cavity 1053.

[0148] When the valve core assembly 1056 is in the first position, the first push rod 1056-1 drives the fourth sealing ring 1057 to block the water flow path between the first distribution chamber 1054-1 and the working chamber 1055. Similarly, the second push rod 1056-2 drives the fourth sealing ring 1057 to block the water flow path between the second distribution chamber 1054-2 and the working chamber 1055.

[0149] When the valve core assembly 1056 is in the second position, the first push rod 1056-1 drives the fifth sealing ring 1058 to block the water flow path between the first distribution chamber 1054-1 and the bypass chamber 1053, and the second push rod 1056-2 drives the fifth sealing ring 1058 to block the water flow path between the second distribution chamber 1054-2 and the bypass chamber 1053.

[0150] See Figure 1 , Figure 2 , Figure 4 and Figure 5 It is understood that the connector assembly also includes a fixing seat 106, which is used to install the water purification component 100 to the required position, and the fixing seat 106 is detachably connected to the connector assembly 105.

[0151] The connector assembly 105 and the fixed base 106 can be detachably assembled by snap-fit, or other assembly methods can be used, such as fixed connection, or the connector assembly 105 and the fixed base 106 can be integrally formed, so that the connector assembly 105 and the fixed base 106 form an integral structure.

[0152] See Figure 2 It is understood that the fixed base 106 includes a first base body 1061 and a second base body 1062; the second base body 1062 is connected to one side of the first base body 1061, and the second base body 1062 is configured with a position suitable for the installation of the receiving body, and the receiving body is connected to the fixed base 106 through the second base body 1062.

[0153] During use, the fixing base 106 can be fixed to an external device. The second base body 1062 is connected to the front of the fixing base 106, and the back of the fixing base 106 is provided with bolt holes for connecting to the external device. To ensure the connection effect, the second base body 1062 is provided with a pipe seat for engaging the main water inlet 1051 and a pipe seat for engaging the main water outlet 1052. The pipe seat for engaging the main water inlet 1051 is engaged on the outer wall of the main water inlet 1051, and the pipe seat for engaging the main water outlet 1052 is engaged on the outer wall of the main water outlet 1052, thereby ensuring the stability of the entire base body.

[0154] It should be noted that the main inlet 1051 can also be located on the first outer shell 1011, and the main outlet 1052 can be located on the inner shell 102. That is, the main inlet 1051 is located at one end of the first outer shell 1011 and is connected to the first flow channel 1013, while the main outlet 1052 is located at one end of the inner shell 102 and is connected to the third flow channel 1031.

[0155] refer to Figure 1 , Figure 2 , Figure 6 and Figure 7 It is understood that, in order to prevent water from flowing out of the water purification component 100 when the filter element 103 is pulled out or replaced, the water purification component 100 may also include a water-stopping component 107. A water-stopping cavity 1011-2 is constructed inside the first housing 1011 and located on the water outlet side of the filter element 103. The water-stopping component 107 is movably disposed in the water-stopping cavity 1011-2, that is, the water-stopping component 107 can move within the water-stopping cavity 1011-2 and is suitable for switching between a first position and a second position.

[0156] See Figure 6 and Figure 7 It is understood that the external structure of the water-stop component 107 has a first channel 1074, which can also be understood as the first channel 1074 being formed between the first outer shell 1011 and the water-stop component 107. This is equivalent to the water-stop component 107 being placed after the water-stop cavity 1011-2, and there is a water passage gap between it and the cavity wall of the water-stop cavity 1011-2. This water passage gap can be opened and closed as the water-stop component 107 moves in the water-stop cavity 1011-2.

[0157] like Figure 6 and Figure 7 As shown, the internal structure of the water-stopping component 107 includes a second channel 1075. A one-way valve 1073 is provided in the second channel 1075 to realize the opening and closing of the water passage based on the pressure difference. The one-way valve 1073 can not only restrict the flow direction of the water body, but also realize the opening and closing of the water passage based on the pressure difference on both sides.

[0158] like Figure 6 As shown, when the water-stopping component 107 is in the first position, the water-stopping component 107 can block the first channel 1074. At this time, the one-way valve 1073 judges that the pressure difference on both sides is small and blocks the water path, that is, the one-way valve 1073 blocks the second channel 1075.

[0159] The water-stopping component 107 is detachably connected to the receiving component 105. When it is determined that the filter element 103 needs to be pulled out or replaced, the water purification component 100 is removed from the receiving component 105. At this time, the water-stopping component 107 moves to the outside of the first housing 1011 to abut against the inner wall of the first housing 1011, that is, the water-stopping component 1077 abuts against the cavity wall of the water-stopping cavity 1011-2, thereby blocking the first channel 1074 and preventing water from flowing through the first channel 1074. The one-way valve 1073 determines that the pressure difference on both sides is small and also blocks the second channel 1075, preventing water from flowing through the second channel 1075, so as to realize the water-stopping function of the water-stopping component 107.

[0160] like Figure 7 As shown, when the water-stopping component 107 is in the second position, the water-stopping component 107 can open the first channel 1074. At this time, the one-way valve 1073 judges that the pressure difference on both sides is large and opens the water path, that is, the one-way valve 1073 opens the second channel 1075.

[0161] like Figure 7 As shown, the water purification component 100 is assembled on the receiving component 105. At this time, the receiving component 105 squeezes the water-stopping component 107, causing the water-stopping component 107 to move into the interior of the first housing 1011. At this time, there is a water passage gap between the water-stopping component 107 and the first housing 1011, which is equivalent to the water-stopping component 107 opening the first channel 1074, allowing water to flow through the first channel 1074. The one-way valve 1073 judges that the pressure difference on both sides is large, and also opens the second channel 1075, allowing water to flow through the second channel 1075, so as to realize the normal working state of the water-stopping component 107.

[0162] By detachably connecting the water-stop component 107 to the water purification component 100, when it is determined that the filter element 103 needs to be removed or replaced, the water purification component 100 is detached from the connector component 105. Since the water-stop component 107 is provided on the water outlet side of the water purification component 100, the water-stop component 107 can prevent the water in the water purification component 100 from continuing to overflow, thereby effectively preventing dirty water from overflowing when the user inserts or removes the filter element 103, thus improving the user's filter replacement experience.

[0163] See Figure 2 , Figure 6 and Figure 7It is understood that the water-stopping assembly 107 may include a water-stopping housing 1071, which is a shell-shaped structure with an internal cavity. The inner shell 102 extends outward from the water outlet side of the filter element 103 to form a fixing part 1024. The shape of the water-stopping housing 1071 is adapted to the shape of the fixing part 1024. The water-stopping housing 1071 can be fitted on the outside of the fixing part 1024 or on the inside of the fixing part 1024, so that the water-stopping housing 1071 can move along the outer or inner side wall of the fixing part 1024.

[0164] See Figure 2 , Figure 6 and Figure 7 It is understood that an elastic element 1072 is provided inside the water-stop shell 1071. One end of the elastic element 1072 is connected to the cavity wall of the receiving cavity, and the other end of the elastic element 1072 is connected to the fixing part 1024. When the elastic element 1072 is compressed and undergoes elastic deformation, the fixing part 1024 can be completely contained in the receiving cavity. When the elastic element 1072 recovers its elastic deformation, the water-stop shell 1071 is subjected to the elastic restoring force of the elastic element 1072 and moves in the water-stop cavity 1011-2, causing the fixing part 1024 to protrude from the receiving cavity. The water-stop shell 1071 is movably mounted on the fixing part 1024 through the elastic element 1072, that is, the water-stop shell 1071 can move relative to the fixing part 1024. The elastic element 1072 can be a spring.

[0165] It is understood that the second channel 1075 can be formed inside the water-stop shell 1071, or it can be partially formed inside the fixing part 1024 and partially formed inside the water-stop shell 1071. The second channel 1075 can also be constructed in the water-stop shell 1071 or the fixing part 1024.

[0166] like Figure 6 As shown, when it is determined that the filter element 103 needs to be removed or replaced, the water-stopping component 107 is removed from the connector component 105, which is equivalent to canceling the squeezing action of the connector component 105 on the water-stopping housing 1071. The elastic element 1072 restores its elastic deformation and drives the water-stopping housing 1071 to move axially along the fixing part 1024 until the water-stopping housing 1071 abuts against the inner wall of the first outer shell 1011 and the water passage gap between it and the first outer shell 1011 disappears. At this time, the water-stopping component 107 is in the first position, blocking the first channel 1074. The one-way valve 1073 judges that the pressure difference between the two ends is small and blocks the second channel 1075, so as to realize the water-stopping function of the water-stopping component 107.

[0167] like Figure 7As shown, when the water-stopping component 107 is installed on the receiving component 105, it is equivalent to the receiving component 105 applying a squeezing action to the water-stopping housing 1071. The position of the fixing part 1024 remains unchanged, the elastic element 1072 undergoes elastic deformation under pressure, and the water-stopping housing 1071 moves axially along the fixing part 1024, creating a water passage gap between it and the inner wall of the first outer shell 1011. At this time, the water-stopping component 107 is in the second position, opening the first channel 1074. The one-way valve 1073 determines that the pressure difference on both sides is large, and then controls the opening of the second channel 1075 so that the water purification component 100 is in normal working condition.

[0168] See Figure 2 , Figure 6 and Figure 7 It is understandable that, in order to improve the water-stopping effect of the water-stopping component 107, the water-stopping component 107 may also include a sixth sealing ring 1071-2. The sixth sealing ring 1071-2 is sleeved on the water-stopping housing 1071 and can move up and down within the water-stopping cavity 1011-2 as the water-stopping housing 1071 moves. The sixth sealing ring 1071-2 may be a rubber sealing ring.

[0169] like Figure 6 As shown, when it is determined that the filter element 103 needs to be removed or replaced, the water-stopping component 107 is removed from the connector component 105, which is equivalent to canceling the squeezing action of the connector component 105 on the water-stopping housing 1071. The elastic element 1072 restores its elastic deformation, driving the water-stopping housing 1071 to move axially along the fixing part 1024. The sixth sealing ring 1071-2 moves with the water-stopping housing 1071 and forms a sealing surface with the inner wall of the water-stopping cavity 1011-2 to block the first channel 1074. The one-way valve 1073 determines that the pressure difference between the two ends is small and blocks the second channel 1075 to realize the water-stopping function of the water-stopping component 107.

[0170] like Figure 7 As shown, when the water-stopping component 107 is installed on the receiving component 105, it is equivalent to the receiving component 105 applying a squeezing action to the water-stopping housing 1071. The position of the fixing part 1024 remains unchanged, the elastic element 1072 undergoes elastic deformation under pressure, the water-stopping housing 1071 moves axially along the fixing part 1024, the sixth sealing ring 1071-2 moves with the water-stopping housing 1071, releasing the sealing surface formed with the inner wall of the water-stopping cavity 1011-2, so as to open the first channel 1074. The one-way valve 1073 judges that the pressure difference on both sides is large, so it controls the opening of the second channel 1075 so that the water purification component 100 is in normal working condition.

[0171] See Figure 2 , Figure 6 and Figure 7It is understandable that, in order to improve the water-stopping effect of the water-stopping component 107, a sealing protrusion 1076 can also be provided on the inner wall of the first housing 1011. The sealing protrusion 1076 is located on the inner wall of the water-stopping cavity 1011-2 and is used to cooperate with the sixth sealing ring 1071-2 to achieve the water-stopping function. The sealing protrusion 1076 can be partially provided on the inner wall of the first housing 1011, or it can be set as an annular structure along the radial direction of the first housing 1011.

[0172] like Figure 6 As shown, when it is determined that the filter element 103 needs to be removed or replaced, the water-stopping component 107 is removed from the connector component 105, which is equivalent to canceling the squeezing action of the connector component 105 on the water-stopping housing 1071. The elastic element 1072 restores its elastic deformation, driving the water-stopping housing 1071 to move axially along the fixed part 1024. The sixth sealing ring 1071-2 moves with the water-stopping housing 1071 and abuts against the sealing protrusion 1076 to form a sealing surface, thereby blocking the first channel 1074. The one-way valve 1073 determines that the pressure difference between the two ends is small and blocks the second channel 1075, so as to realize the water-stopping function of the water-stopping component 107.

[0173] Conversely, such as Figure 7 As shown, when the water-stopping component 107 is installed on the connector component 105, it is equivalent to the connector component 105 applying a squeezing action to the water-stopping housing 1071. The elastic element 1072 undergoes elastic deformation under pressure, and the water-stopping housing 1071 moves axially along the fixing part 1024. The sixth sealing ring 1071-2 moves with the water-stopping housing 1071, releasing the sealing surface formed between it and the sealing protrusion 1076, so as to open the first channel 1074. The one-way valve 1073 judges that the pressure difference on both sides is large, and then controls the opening of the second channel 1075 so that the water purification component 100 is in normal working condition.

[0174] See Figure 2 , Figure 6 and Figure 7 It is understood that the water-stopping component 107 may also include at least one seventh sealing ring 1071-3, that is, the water-stopping component 107 includes one or two seventh sealing rings 1071-3. The seventh sealing ring 1071-3 is coaxially arranged with the sixth sealing ring 1071-2 and is also sleeved on the water-stopping housing 1071, and moves synchronously with the water-stopping housing 1071.

[0175] The seventh sealing ring 1071-3 can be a rubber sealing ring, which is set at the end of the water-stop housing 1071 facing the receiving assembly 105, so that the water-stop assembly 107 can ensure a good sealing effect between the water-stop housing 1071 and the receiving assembly 105 during the position switching process.

[0176] See Figure 2 , Figure 6and Figure 7 It is understandable that, during the position switching process of the water-stop component 107, in order to ensure a good sealing effect between the water-stop housing 1071 and the fixing part 1024, the water-stop component 107 may also include a second sealing ring 1023. The second sealing ring 1023 is sleeved on the fixing part 1024 and is located between the water-stop housing 1071 and the fixing part 1024. It can be a rubber sealing ring, which is used to ensure the sealing between the water-stop housing 1071 and the fixing part 1024 during the movement of the water-stop component 107.

[0177] See Figure 2 , Figure 6 and Figure 7 It is understandable that, in order to prevent the water-stop shell 1071 from detaching from the fixing part 1024, a limiting protrusion 1022 is provided on the fixing part 1024, and a limiting groove 1071-1 is provided on the water-stop shell 1071 at the position corresponding to the limiting protrusion 1022. The limiting groove 1071-1 is slidably sleeved on the limiting protrusion 1022 so that the water-stop shell 1071 moves relative to the fixing part 1024 within the stroke limited by the limiting groove 1071-1, thereby preventing the water-stop shell 1071 from detaching from the fixing part 1024.

[0178] When the water-stopping assembly 107 is in the first position, the elastic element 1072 recovers its elastic deformation, driving the water-stopping housing 1071 to move axially along the fixing part 1024, so that the limiting protrusion 1022 abuts against one side of the limiting groove 1071-1; when the water-stopping assembly 107 is in the second position, the elastic element 1072 is compressed and undergoes elastic deformation, and the water-stopping housing 1071 moves axially along the fixing part 1024, so that the limiting protrusion 1022 abuts against the other side of the limiting groove 1071-1.

[0179] The engagement of the limiting protrusion 1022 with the limiting groove 1071-1 not only prevents the water-stop shell 1071 from detaching from the fixing part 1024, but also further ensures the water-stopping function of the water-stopping component 107. When the water-stopping component 107 is in the first position, it blocks the first channel 1074. When the one-way valve 1073 determines that the pressure difference between the two ends is small, it blocks the second channel 1075, thus realizing the water-stopping function of the water-stopping component 107. When the water-stopping component 107 is in the second position, it opens the first channel 1074. When the one-way valve 1073 determines that the pressure difference between the two ends is large, it opens the second channel 1075.

[0180] See Figure 2 , Figure 6 and Figure 7It is understood that, in order to ensure that the water-stopping component 107 can move along the set path, a guide structure can also be provided between the water-stopping component 107 and the fixing part 1024. The guide structure can include a guide protrusion 1025 provided on the outer wall of the fixing part 1024, and a guide groove (not shown in the figure) provided on the inner wall of the water-stopping housing 1071 corresponding to the position of the guide protrusion 1025. When the water-stopping housing 1071 moves along the outer wall of the fixing part 1024, the guide protrusion 1025 moves in the guide groove.

[0181] The position and shape of the guide groove and guide protrusion 1025 can be adjusted according to the needs of use. The guide protrusion 1025 can be arranged along the axial direction of the fixing part 1024 so that the water-stopping assembly 107 can move up and down along the axial direction of the fixing part 1024.

[0182] It should be noted that the first channel 1074 can be configured as either an inlet channel or an outlet channel, and similarly, the second channel 1075 can be configured as either an inlet channel or an outlet channel. When the first channel 1074 and the second channel 1075 are used as inlet or outlet channels, they need to correspond to the inlet and outlet directions of the first flow channel 1013, the second flow channel 1014, and the third flow channel 1031.

[0183] See Figure 2 , Figure 6 and Figure 7 When the first channel 1074 is the water inlet channel and the second channel 1075 is the water outlet channel, the first channel 1074 is connected to the first flow channel 1013 and the second channel 1075 is connected to the third flow channel 1031. The water-stopping component 107 is assembled onto the water purification component 100, and then the water purification component 100 with the water-stopping component 107 is assembled onto the receiving component 105. Water enters the first channel 1074 from the main inlet 1051, and then flows into the first flow channel 1013 from the first channel 1074. After entering the water storage chamber 1041 from the first flow channel 1013, the water can be temporarily stored in the water storage chamber 1041. When the user needs to use water, part of the water in the water storage chamber 1041 enters the second flow channel 1014, and then permeates into the filter element 103 for filtration. The water filtered by the filter element 103 flows out from the third flow channel 1031 inside the filter element 103, enters the second channel 1075, and flows out from the second channel 1075 to the main outlet 1052.

[0184] It should be noted that during the assembly process of the water purification component 100, the first sealing member 1044, the second sealing member 1032, and the third sealing ring 1032-1 can be glued and fixed to both ends of the filter element 103 using food-grade adhesive. Then, the second sealing ring 1023 is assembled onto the inner shell 102, and the inner shell 102 is fitted over the outside of the filter element 103, which has been sealed at both ends. After the sixth sealing ring 1071-2 and the seventh sealing ring 1071-3 are assembled at their respective positions on the water-stop shell 1071, a one-way valve 1073 and an elastic member 1072 are installed inside the water-stop shell 1071 to form the water-stop component 107.

[0185] The water-stop shell 1071 is then engaged with the limiting protrusion 1022 via the limiting groove 1071-1, thus assembling the water-stop shell 1071 with the inner shell 102. Finally, the first outer shell 1011 is inserted from the top of the inner shell 102, and the second outer shell 1012 is placed against the bottom of the support member 104, completing the docking of the first outer shell 1011 and the second outer shell 1012. The first outer shell 1011 and the second outer shell 1012 are then rotated and welded to complete the overall assembly of the water purification component 100.

[0186] The water purification component 100 provided in this application embodiment has at least one of the following technical effects:

[0187] By incorporating a water storage chamber 1041 within the water purification component 100, the integration level of the water purification component 100 is increased, enabling it to function not only as a purification unit but also as a water storage unit. The water storage chamber 1041 replaces the independent water tank structure found in related technologies, thus eliminating the need for a separate water tank. This simplifies the structural design of the water system and reduces its footprint. Furthermore, the elimination of connecting pipes and joints between the water tank and the water purification component 100 effectively avoids the risk of structural leakage, resulting in higher product reliability and a better user experience.

[0188] By improving the water purification component 100, the water system is simplified. Replacing the water purification component 100 completes the replacement of the water storage space in the entire water system, further ensuring the safety of users' water use.

[0189] By incorporating a spiral flow channel in the water purification component 100, water enters through the main inlet 1051 and flows along the extension direction of the spiral flow channel towards the water storage chamber 1041. This effectively extends the water's flow path, ensuring that the water that first enters the water purification component 100 flows out first, achieving a first-in, first-out (FIFO) water flow. This effectively prevents the accumulation of stagnant water and the occurrence of water mixing.

[0190] By detachably connecting the water-stop component 107 to the water purification component 100, when it is determined that the filter element 103 needs to be removed or replaced, the water purification component 100 is detached from the connector component 105. Since the water-stop component 107 is provided on the water outlet side of the water purification component 100, the water-stop component 107 can prevent the water in the water purification component 100 from continuing to overflow, thereby effectively preventing dirty water from overflowing when the user inserts or removes the filter element 103, thus improving the user's filter replacement experience.

[0191] See Figure 8 and Figure 9 Another aspect of this application provides a refrigeration device 600, including a refrigeration chamber and a water-using device 500, as well as the aforementioned water purification component 100; the water purification component 100 is disposed in the refrigeration chamber, and the main outlet 1052 of the water purification component 100 is connected to the water-using device 500.

[0192] In some embodiments of this application, the refrigeration device 600 further includes a valve assembly 200, the inlet of which is connected to the main outlet 1052 of the water purification component 100, and the outlet of which is connected to at least one water-using device 500.

[0193] In some embodiments of this application, the water-using device 500 includes a first ice maker 501, a second ice maker 502, and a distributor 503; the refrigeration compartment includes a refrigerator compartment 601 and a freezer compartment 602, the first ice maker 501 is located in the refrigerator compartment 601, the second ice maker 502 is located in the freezer compartment 602, and the distributor 503 is located on the door 603 of the refrigeration device 600.

[0194] In some applications of this application, such as Figure 9 As shown, the water purification component 100 can be installed in the cold storage compartment 601. The refrigeration equipment 600 also includes multiple water supply pipes. One end of one of the water supply pipes is connected to the water supply system (tap water network), and the other end of the water supply pipe extends into the cold storage compartment 601 and is connected to the main water inlet 1051 of the water purification component 100. Since the water purification component 100 is located in the cold storage compartment 601, the water entering the water purification component 100 can be cooled and then filtered in the low-temperature environment of the cold storage compartment 601. The filtered, low-temperature purified water is supplied to each water-using device 500, allowing users to directly obtain cooled water from the distributor 503 for use.

[0195] During use, the water purification component 100 of the refrigeration equipment 600 can be connected to an external tap water pipe, i.e., an external water source. The valve component 200 can be a one-inlet, three-outlet valve, which has one liquid inlet and three liquid outlets. The liquid inlet of the valve component 200 is connected to the main water outlet 1052 of the water purification component 100. Each liquid outlet of the valve component 200 is connected to the first ice maker 501, the second ice maker 502 and the distributor 503 through corresponding connecting pipes, so that the water purified by the water purification component 100 can be selectively distributed to the first ice maker 501, the second ice maker 502 and the distributor 503 of the refrigeration equipment 600.

[0196] The purified water output by the water purification component 100 can be controlled and distributed to the first ice maker 501, the second ice maker 502 and the distributor 503 through a one-in-three-out valve, which can meet the ice-making needs of the first ice maker 501 and the second ice maker 502. In addition, users can also take ice water through the distributor 503 without opening the door 603, which is more convenient.

[0197] Furthermore, by incorporating a water storage chamber 1041 within the water purification component 100, the existing water tank structure is integrated with the water purification component 100, simplifying the water supply path structure of the water-using device 500. This simplified water supply path not only extends the internal water flow path, facilitating first-in-first-out water flow, but also allows the water storage chamber 1041 to store water. After the water purification component 100 is installed within the refrigerator compartment, the water storage chamber 1041 utilizes the refrigerator compartment's temperature to cool the internal water. This cooled water is then supplied to the distributor 503, enhancing the user experience.

[0198] According to the refrigeration equipment 600 provided in this application, by setting a water storage chamber 1041 for water storage in the water purification component 100, the integration level of the water purification component 100 is increased, thus enabling the water purification component 100 to not only have purification functions but also water storage functions. This replaces the water tank that is separately set in the water purification component 100 in related technologies, i.e., the water tank setting is eliminated, thereby simplifying the structural design and reducing the space occupied by the structure; at the same time, the connecting pipes and connecting joints between the water tank and the water purification component 100 are eliminated, effectively avoiding the risk of structural leakage, thereby making the product more reliable and providing a better user experience.

[0199] Finally, it should be noted that the above embodiments are only used to illustrate this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of this application do not depart from the spirit and scope of the technical solutions of this application and should be covered within the scope of the claims of this application.
