Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and in particular to a water purification component and refrigeration equipment. Background Technology

[0002] In related technologies, when replacing the filter cartridge in a water purification component, water inside the cartridge overflows, requiring the user to clean it up. This increases the time required for filter replacement, resulting in a poor user experience. To address this, a water-stop structure is installed at the outlet of the water purification component. While this prevents water from overflowing during filter replacement, it creates resistance during installation, making it difficult to reposition the water purification component and resulting in low installation efficiency. Summary of the Invention

[0003] 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 purification component that can reduce the resistance during the installation process and improve the installation efficiency of the water purification component.

[0004] This application also provides a refrigeration device.

[0005] The water purification component provided according to the embodiments of this application includes:

[0006] First outer shell;

[0007] The second outer shell is disposed inside the first outer shell and forms a water-stopping cavity with the first outer shell;

[0008] A water-stopping mechanism is movably disposed within the water-stopping cavity. The water-stopping mechanism includes a water-stopping shell, which comprises a housing portion and a first sealing portion. The first sealing portion is located inside the housing portion, and a second housing portion is slidably and sealingly connected to the first sealing portion. The water-stopping mechanism also includes a one-way valve and an elastic element, which abuts against the housing portion and the second housing portion. A first channel is formed between the housing portion and the first housing portion, a second channel is formed between the housing portion and the first sealing portion, and a third channel is formed inside the first sealing portion. The one-way valve is located within the third channel.

[0009] The housing portion moves downward to compress the elastic element and cause it to undergo elastic deformation. The gap between the housing portion and the inner wall of the first outer shell gradually increases to connect the first channel and the second channel. The one-way valve opens the third channel, and the water-stopping mechanism moves to the first position.

[0010] When the water-stopping mechanism moves to the second position, the housing part blocks the first channel and the second channel, and the one-way valve blocks the third channel;

[0011] The housing portion is provided with a water passage hole for connecting the first channel and the second channel. When there is a gap between the housing portion and the first outer shell, the water in the first channel flows into the second channel through the water passage hole.

[0012] According to the embodiments of this application, the water purification component provides a first sealing part inside the housing part, so that the second outer shell is sealed to the first sealing part, which is equivalent to reducing the interaction area between the housing part and the water. When the water-stopping mechanism moves in the water-stopping cavity, the pressure difference between the inner and outer sides of the housing part can be balanced, thereby reducing the resistance during the installation process of the water purification component and improving the installation efficiency of the water purification component.

[0013] Compared to related technologies, when installing a water purification component onto a connector assembly, firstly, the resistance of the elastic element within the connector assembly needs to be overcome to compress it and cause elastic deformation; secondly, the resistance of the elastic element within the water purification component needs to be overcome to compress it and cause elastic deformation; finally, as the channel gradually opens, the water pressure exerted by the water-stop shell also needs to be overcome. Therefore, the installation of the water purification component involves significant resistance, is time-consuming and labor-intensive, resulting in low assembly efficiency.

[0014] In this application, a first sealing part is provided inside the housing part, so that the second outer shell is sealed to the first sealing part, which is equivalent to reducing the contact area between the housing part and the water, thereby reducing the movement resistance of the water-stopping outer shell and making installation easier.

[0060] The water purification component 100 provided in this application is applicable to refrigeration equipment 80 such as refrigerators, ice bars, freezers, wine cabinets, and refrigerated cabinets. The water purification component 100 provided in this application will be described in detail below with reference to specific embodiments.

[0061] See details Figures 1 to 5 The first aspect of this application provides a water purification component 100, which includes a first outer shell 10, a second outer shell 20, and a water-stopping mechanism 30. Both the first outer shell 10 and the second outer shell 20 can be cylindrical structures with a hollow structure. The second outer shell 20 is disposed inside the first outer shell 10, and a water-stopping cavity 101 is formed between the second outer shell 20 and the first outer shell 10. The water-stopping mechanism 30 is movably disposed in the water-stopping cavity 101 and can be switched between a first position and a second position.

[0062] like Figure 2 , Figure 3 and Figure 4 As shown, the water-stopping mechanism 30 includes a water-stopping housing 301, a one-way valve 302, and an elastic element 303. The water-stopping housing 301 is connected to the second housing 20 through the elastic element 303, so that the elastic element 303 drives the water-stopping housing 301 to move up and down in the water-stopping cavity 101 when elastic deformation occurs and elastic deformation is restored. The water-stopping housing 301 includes a housing part 3011 and a first sealing part 3012. A first channel 3013 is formed between the housing part 3011 and the first housing 10, and a second channel 3014 is formed between the housing part 3011 and the first sealing part 3012. A third channel 3015 is formed inside the first sealing part 3012. The one-way valve 302 is located in the third channel 3015 and can be fixed inside the housing part 3011 by a fixing element 305.

[0063] like Figure 2As shown, when the water-stopping mechanism 30 is in the first position, that is, when the water purification component 100 is installed on the receiving component 60, the receiving component 60 applies a downward squeezing force to the housing part 3011, causing the housing part 3011 to move downward, thereby compressing the elastic element 303 and causing it to undergo elastic deformation. The gap between the housing part 3011 and the inner wall of the first outer shell 10 gradually increases, so that the first channel 3013 and the second channel 3014 are connected. After the first channel 3013 and the second channel 3014 are connected, the one-way valve 302 can open the third channel 3015 according to the pressure difference on both sides.

[0064] like Figure 3 As shown, when the water-stopping mechanism 30 is in the second position, that is, when the water purification component 100 is removed from the connector assembly 60, the connector assembly 60 releases the downward squeezing force on the housing part 3011, causing the housing part 3011 to move upward under the reset action of the elastic member 303. The gap between the housing part 3011 and the inner wall of the first outer shell 10 gradually narrows, so as to block the connection between the first channel 3013 and the second channel 3014. The one-way valve 302 can block the third channel 3015 according to the pressure difference on both sides.

[0065] It is understandable that, firstly, by providing a first sealing part 3012 inside the housing part 3011, the second outer shell 20 is sealed to the first sealing part 3012, which is equivalent to reducing the interaction area between the housing part 3011 and water. When the water-stopping mechanism 30 moves in the water-stopping cavity 101, the pressure difference between the inner and outer sides of the housing part 3011 can be balanced, thereby reducing the resistance during the installation of the water purification component 100 and improving the installation efficiency of the water purification component 100.

[0066] Secondly, by constructing a second channel 3014 that can communicate with the first channel 3013 between the housing part 3011 and the first sealing part 3012, as the water flow channel gradually opens, the water flows down through the second channel 3014, further reducing the area of ​​the water acting on the water-stopping housing 301, thereby reducing the movement resistance of the water-stopping housing 301, reducing the resistance during the installation of the water purification component 100, and improving the installation efficiency of the water purification component 100.

[0067] Compared to related technologies, when the water purification component 100 is installed on the connector component 60, firstly, the resistance of the elastic element inside the connector component 60 needs to be overcome to compress the elastic element and cause it to undergo elastic deformation; secondly, the resistance of the elastic element 303 inside the water purification component 100 needs to be overcome to compress the elastic element 303 and cause it to undergo elastic deformation; finally, as the channel gradually opens, the water pressure on the water-stop shell 301 also needs to be overcome. Therefore, the installation of the water purification component 100 involves greater resistance, is more time-consuming and labor-intensive, and results in lower assembly efficiency.

[0068] In this application, since a second channel 3014 that can communicate with the first channel 3013 is constructed between the housing portion 3011 and the first sealing portion 3012, when the water purification component 100 is installed on the receiving assembly 60, the water purification component 100 only needs to overcome the resistance of the elastic member 303 and the elastic member inside the receiving assembly 60, without having to overcome the pressure difference between the inside and outside of the water-stopping housing 301, making installation easier.

[0069] like Figure 2 , Figure 3 and Figure 5 As shown, a water passage 3011-1 for connecting the first channel 3013 and the second channel 3014 is provided in the housing part 3011. When there is a gap between the housing part 3011 and the first outer shell 10, the water in the first channel 3013 can flow into the second channel 3014 through the water passage 3011-1.

[0070] If the water passage hole 3011-1 is not provided on the housing part 3011, when there is a gap between the housing part 3011 and the first outer shell 10, the water entering the water purification component 100 flows along the outer surface of the housing part 3011. The contact area between the housing part 3011 and the water is large, that is, the pressure difference area between the inner and outer sides of the housing part 3011 is large. During the installation process, the movement resistance of the housing part 3011 is large, the installation is time-consuming and labor-intensive, and the installation efficiency is low.

[0071] Therefore, as long as it is ensured that the water does not flow along the outer surface of the shell portion 3011, thereby reducing the contact area between the water and the outer wall of the shell portion 3011, and the first channel 3013 and the second channel 3014 are connected, the water passage 3011-1 can be set at any position on the shell portion 3011. However, in order to further reduce the movement resistance of the shell portion 3011, the water passage 3011-1 is arranged circumferentially through the stepped surface of the shell portion 3011. The shape and number of the water passage 3011-1 are not specifically limited.

[0072] like Figures 2 to 5 As shown, it can be understood that in order to improve the blocking effect of the first channel 3013 and the second channel 3014, a first sealing ring 3011-3 is provided on the outer surface of the housing part 3011, and a sealing protrusion 102 is provided on the inner wall of the first housing 10 to cooperate with the first sealing ring 3011-3 for blocking the first channel 3013 and the second channel 3014.

[0073] Since the housing portion 3011 can move up and down relative to the first outer shell 10 within the water-stopping cavity 101, the first sealing ring 3011-3 can also move up and down with the housing portion 3011 relative to the first outer shell 10 within the water-stopping cavity 101. When the water purification component 100 is detached from the receiving assembly 60, the receiving assembly 60 releases the downward pressing force on the housing portion 3011, the elastic member 303 recovers its elastic deformation, and drives the housing portion 3011 to move upward relative to the first outer shell 10 within the water-stopping cavity 101, so that the first sealing ring 3011-3 abuts against the sealing protrusion 102, forming a sealing surface between the sealing ring and the sealing protrusion 102 to block the first channel 3013. By using the sealing ring and the sealing protrusion 102 to block the first channel 3013, the blocking effect between the first channel 3013 and the second channel 3014 can be further ensured.

[0074] Of course, the first sealing ring 3011-3 can also be provided on the inner wall of the first outer shell 10. Correspondingly, the sealing protrusion 102 is provided on the shell part 3011. When the shell part 3011 moves up and down relative to the first outer shell 10 in the water-stopping cavity 101, the sealing protrusion 102 and the first sealing ring 3011-3 can also cooperate to block the first channel 3013.

[0075] Alternatively, a sealing ring can be provided on the housing portion 3011 at the position of the water passage hole 3011-1, thereby blocking the first channel 3013 and the second channel 3014 through the sealing ring.

[0076] like Figures 2 to 5 As shown, it can be understood that at least one second sealing ring 3011-5 is also provided at the top of the housing portion 3011 to achieve a sealed connection between the water purification component 100 and the receiving assembly 60. To improve the sealing effect between the water purification component 100 and the receiving assembly 60, at least one third sealing ring 104 can also be provided at the end of the first housing 10.

[0077] like Figures 2 to 5 As shown, the second outer casing 20 includes a main body 201 and a mounting portion 202. The mounting portion 202 is connected to the water outlet end of the main body 201. A second sealing portion 203 is coaxially disposed inside the mounting portion 202. The second sealing portion 203 is sealed to the first sealing portion 3012 by a fourth sealing ring 2031. An elastic element 303 is sleeved on the outside of the first sealing portion 3012 and the second sealing portion 203. When the elastic element 303 undergoes elastic deformation or recovers its elastic deformation, the second sealing portion 203 moves up and down along the inner wall of the first sealing portion 3012, and the two always maintain a sealed state.

[0078] This means that the diameter of the second sealing part 203 is smaller than the diameter of the mounting part 202, thereby reducing the sealing contact area between the mounting part 202 and the housing part 3011. This reduces the resistance when the second sealing part 203 moves up and down along the inner wall of the first sealing part 3012, thereby reducing the movement resistance of the water-stopping housing 301 in the water-stopping cavity 101. This reduces the resistance during the installation of the water purification component 100 and improves the installation efficiency of the water purification component 100.

[0079] To further reduce the resistance during the installation of the water purification component 100, the second sealing part 203 is fitted inside the first sealing part 3012 so that when water flows into the second channel 3014 from the water passage 3011-1, it can flow along the outer surface of the first sealing part 3012, avoiding entering the sealing surface between the second sealing part 203 and the first sealing part 3012, thereby hindering the movement of the housing part 3011.

[0080] like Figure 4 and Figure 5 As shown, it can be understood that a limiting groove 3011-2 is provided on the mounting part 202, and a limiting protrusion 2021 that cooperates with the limiting groove 3011-2 is provided on the housing part 3011. The housing part 3011 is adapted to move within the water-stopping cavity 101 along the limiting groove 3011-2 under the action of the elastic member 303. Through the cooperation of the limiting groove 3011-2 and the limiting protrusion 2021, not only can the housing part 3011 be prevented from detaching from the mounting part 202, but also a guide can be provided for the movement of the housing part 3011 outside the mounting part 202.

[0081] When the water-stopping mechanism 30 is in the first position, the receiving assembly 60 applies a downward squeezing force to the housing part 3011, causing the housing part 3011 to move downward, thereby compressing the elastic member 303 and causing it to undergo elastic deformation. The housing part 3011 moves axially along the mounting part 202, causing the limiting protrusion 2021 to abut against the first end of the limiting groove 3011-2.

[0082] When the water-stopping mechanism 30 is in the second position, the receiving assembly 60 releases the downward squeezing force on the housing part 3011, the elastic member 303 restores its elastic deformation, and drives the housing part 3011 to move axially along the mounting part 202, so that the limiting protrusion 2021 abuts against the second end of the limiting groove 3011-2.

[0083] The limiting distance of the limiting groove 3011-2 can be set to the maximum stroke of the housing part 3011. Therefore, when the limiting protrusion 2021 abuts against the first end of the limiting groove 3011-2, the housing part 3011 can connect the first channel 3013 and the second channel 3014; when the limiting protrusion 2021 abuts against the second end of the limiting groove 3011-2, the housing part 3011 can block the first channel 3013 and the second channel 3014. This allows the housing part 3011 and the mounting part 202 to cooperate through the limiting protrusion 2021 and the limiting groove 3011-2, preventing the housing part 3011 from detaching from the mounting part 202 and further improving the water-stopping movement of the water-stopping mechanism 30, ensuring the stable and reliable movement of the water-stopping mechanism 30.

[0084] Of course, the limiting slot 3011-2 can also be provided on the housing part 3011, and the limiting protrusion 2021 that cooperates with the limiting slot 3011-2 can be provided on the mounting part 202. The specific setting can be determined according to the usage requirements.

[0085] like Figure 4 and Figure 5 As shown, in order to reduce the torque effect of the limiting protrusion 2021 and the limiting groove during the mating and moving process, and to extend the service life of the limiting protrusion 2021 and the limiting groove, a slider 2022 can be provided on either the mounting part 202 or the housing part 3011. The slider 2022 can be provided at intervals with the limiting protrusion 2021. A groove 3011-6 that mates with the slider 2022 is provided on the other of the mounting part 202 and the housing part 3011.

[0086] like Figure 2 and Figure 3 As shown, it can be understood that a guide portion 103 is provided inside the first outer shell 10, and at least a portion of the shell portion 3011 moves within the water-stopping cavity 101 along the extending direction of the guide portion 103. The guide portion 103 is coaxially arranged with the shell of the first outer shell 10, which also reduces the contact area between the first outer shell 10 and the shell portion 3011, thereby facilitating the movement of the shell portion 3011 within the water-stopping cavity 101.

[0087] like Figures 2 to 4 As shown, it can be understood that in order to coordinate the movement of the housing 3011 to open the one-way valve 302, the water purification assembly 100 also includes a valve stem 304. A limiting step 3011-4 is provided on the inner wall of the housing 3011. The first end of the valve stem 304 abuts against the limiting step 3011-4, and the second end of the valve stem 304 abuts against the one-way valve 302. The valve stem 304 is adapted to move with the housing 3011 to open or close the one-way valve 302.

[0088] By configuring the valve stem 304, it moves with the housing portion 3011 to quickly open or close the check valve 302, avoiding any lag in the opening or closing of the check valve 302 based on pressure difference. Simultaneously, the check valve 302 moves synchronously with the housing portion 3011, so that while the first channel 3013 and the second channel 3014 are connected, the third channel 3015 opens simultaneously, reducing the pressure difference between the inner and outer sides of the housing portion 3011 and further reducing the resistance to the movement of the housing portion 3011.

[0089] like Figure 6 and Figure 7 As shown, the inner wall of the housing portion 3011 extends outward to form a valve stem portion 3011-7. The valve stem portion 3011-7 moves with the housing portion 3011, suitable for opening or closing the one-way valve 302. Essentially, in the above embodiment, the valve stem 304 is integrally formed with the housing portion 3011, eliminating the assembly time for the valve stem 304 and effectively improving the assembly efficiency of the water purification component 100. Simultaneously, it avoids the loss of parts during the maintenance and replacement of the water purification component 100.

[0090] Specifically, the valve stem portion 3011-7 can be formed by extending the limiting step 3011-4 in the same direction as the extending direction of the first sealing portion 3012. The length of this extended portion can be determined according to the distance between the one-way valve 302 and the limiting step 3011-4, ensuring that the one-way valve 302 can be opened or closed when the valve stem portion 3011-7 moves up and down with the housing portion 3011.

[0091] like Figures 2 to 4 As shown, it can be understood that the internal structure of the second outer shell 20 has a receiving cavity, the receiving cavity contains a filter element 40, and the internal structure of the filter element 40 has a third flow channel 401, which is connected to the third channel 3015.

[0092] A first flow channel 204 is constructed between the first outer shell 10 and the second outer shell 20. The first flow channel 204 is connected to the first channel 3013 and the second channel, or the first flow channel 204 is connected to the second channel. A second flow channel 205 is constructed between the second outer shell 20 and the filter element 40 and is connected to the first flow channel 204.

[0093] Essentially, the second outer shell 20 and the filter element 40 are both disposed inside the first outer shell 10. The second outer shell 20 is located between the first outer shell 10 and the filter element 40, and there is a gap between the first outer shell 10 and the second outer shell 20 through which water flows, namely the first flow channel 204. There is also a gap between the second outer shell 20 and the filter element 40 through which water flows, namely the second flow channel 205. The filter element 40 has a ring-shaped structure, and a third flow channel 401 is formed inside it. During water filtration, water can permeate through the filter element 40 from the second flow channel 205 and flow out from the third flow channel 401.

[0094] like Figures 2 to 4 As shown, it can be understood that the interior of the first outer shell 10 is provided with a support member 50 suitable for supporting the filter element 40 and the second outer shell 20. The support member 50 and part of the first outer shell 10 form a water storage cavity 501, which is connected to the first flow channel 204 and the second flow channel 205 respectively.

[0095] The support member 50 is mainly used for axial support of the filter element 40, so that there is a certain space between the filter element 40 and the bottom wall of the outer shell assembly, that is, a water storage cavity 501 for acting as a water tank to store water is constructed between the filter element 40 and the bottom wall of the first outer shell 10.

[0096] like Figures 2 to 4 As shown, the support member 50 can be confined to the inner wall surface of the first housing 10, and the water storage cavity 501 can be formed inside the support member 50. This is equivalent to the support member 50 being snapped or overlapped onto the inner wall surface of the first housing 10 to prevent the filter element 40 from continuing to contact the bottom wall of the first housing 10, thereby creating a certain space between the bottom wall of the first housing 10 and the support member 50 to form the water storage cavity 501.

[0097] The support member 50 has a structural shape that is compatible with the filter element 40 and the second outer shell 20, etc. It can be a cylindrical structure used to axially support the filter element 40 and to seal one end of the filter element 40. The interior of the support member 50 is a hollow structure to form a water flow channel and a water storage space.

[0098] The support member 50 has a first end and a second end. The first end has a water inlet that communicates with the first flow channel 204 so that water from the first flow channel 204 enters the water storage chamber 501 through the water inlet. The second end is adapted to abut against the filter element 40 to block the first end of the filter element 40 so that water in the water storage chamber 501 enters the third flow channel 401 inside the filter element 40 after being filtered by the filter element 40. The second end of the filter element 40 can be blocked by a sealing member 402, and an opening is provided on the sealing member 402 to communicate with the third flow channel 401 and the third channel 3015.

[0099] The outer wall of the support member 50 can be aligned with the outer wall of the second outer shell 20 so that there is a water passage gap between the support member 50 and the inner shell, so that the water in the second flow channel 205 continues to enter the water passage gap and enters the water inlet of the water storage chamber 501 from the water passage gap.

[0100] The outer wall of the support member 50 is provided with a support portion 502 and a drainage portion 503 extending radially outward. The support portion 502 is adapted to abut or overlap with the inner wall surface of the first outer shell 10 to fix the support member 50. The diameter of the circle containing the drainage portion 503 is smaller than the diameter of the circle containing the support portion 502. The purpose is to reduce the water passage gap between the support member 50 and the first outer shell 10, thereby reducing the air space inside the water purification assembly 100 and increasing the water storage space inside the water purification assembly 100.

[0101] After installation, because the main outlet 602 of the water purification component 100 is lower than the main inlet 601, air remains trapped in the space between the support member 50 and the first outer shell 10, resulting in the space between the support member 50 and the first outer shell 10 not being fully utilized. Therefore, a radially outwardly extending drainage section 503 is provided on the outer wall of the support member 50 to reduce the gap between the support member 50 and the first outer shell 10, ensuring that water flowing through it must pass through the drainage section 503 to remove the air trapped in the space between the support member 50 and the first outer shell 10.

[0102] like Figures 2 to 5 As shown, it can be understood that a flow guide 206 is provided on the outer side of at least one of the second housing 20 and the support member 50, and the flow guide 206 extends along the central axis of the second housing 20 or the support member 50 to form a spiral structure. By providing the spiral structured flow guide 206 on the outer side of the support member 50, water can move along the flow guide 206, and air inside the water purification assembly 100 is prevented from occupying internal space.

[0103] By providing a guide section 206 on the outside of the second outer shell 20, the first flow channel 204 forms a spiral flow channel. When water is input from the main inlet 601, it flows towards the water storage chamber 501 along the extension direction of the spiral flow channel. This spiral flow channel effectively extends the path of the incoming water, ensuring that the water that first enters the water storage chamber 501 flows out of the outlet first. This facilitates the first filtration of water entering the water quality purification module before it flows out, achieving a first-in, first-out water flow. This effectively prevents the accumulation of stagnant water and the occurrence of mixed water.

[0104] 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.

[0105] like Figures 2 to 4As shown, it can be understood that the outer wall of the support member 50 is provided with a limiting part 504, and the second outer shell 20 abuts against the limiting part 504 to limit the second outer shell 20 from continuing to approach the bottom wall of the first outer shell 10, thereby providing axial support for the second outer shell 20.

[0106] An outlet is provided on the side wall between the limiting part 504 and the second end of the support member 50. The outlet is connected to the second flow channel 205, which means that the water outlet direction is inclined to the side wall of the support member 50, so that the water coming out of the water storage chamber 501 flows more smoothly into the second flow channel 205.

[0107] like Figures 2 to 4 As shown, it can be understood that a snap-fit ​​part 505 is provided at one end of the support member 50 to cooperate with the first housing 10 for installation.

[0108] It should be noted that the first flow channel 204 can be either an inlet or outlet flow channel, the second flow channel 205 can be either an inlet or outlet flow channel, and the third flow channel 401 can also be either an inlet or outlet flow channel. When both the first flow channel 204 and the second flow channel 205 are inlet flow channels and the third flow channel 401 is an outlet flow channel, the first flow channel 204 can be connected to the main inlet 601 of the water purification component 100, and the third flow channel 401 can be connected to the main outlet 602 of the water purification component 100.

[0109] During operation, the water purification component 100 connects to an external water source through its main inlet 601. Water flows from the main inlet 601 into the first flow channel 204 and then into the storage chamber 501 for storage. When the user needs to use the purified water, the water stored in the storage chamber 501 first flows from the storage chamber 501 into the second flow channel 205, then through the filter element 40 into the third flow channel 401, and finally out through the third flow channel 401 to the main outlet 602.

[0110] like Figures 2 to 4 As shown, it can be understood that the first housing 10 may include a housing body 201 and an end cap 90. The housing body 201 and the end cap 90 are detachably connected, that is, the housing body 201 and the end cap 90 may be interference-fitted, snap-fitted or threaded, while ensuring the sealing between the housing body 201 and the end cap 90.

[0111] It should be noted that the filter element 40 can be an activated carbon rod filter element 40, or a filter element 40 made of reverse osmosis membrane that is known in the art. Any purification core material that can achieve water filtration is acceptable.

[0112] like Figure 2 , Figure 3 and Figure 8As shown, it can be understood that the water purification component 100 also includes a connector assembly 60, which includes a connector body and a valve core assembly 605 disposed therein.

[0113] like Figure 8 As shown, the main body of the connector is provided with a main inlet 601 and a main outlet 602. In addition, the main body of the connector is a hollow shell structure, which has a first chamber 603 and a second chamber 604 inside. The water purification component 100 is detachably connected to the cavity wall of the second chamber 604. The valve core component 605 is movably disposed in the first chamber 603. By controlling the position of the valve core component 605 in the first chamber 603, the first chamber 603 is connected to the main inlet 601 and the main outlet 602 to achieve internal circulation, ensuring that the water path between the main inlet 601 and the main outlet 602 is connected, and preventing water from overflowing when the filter element 40 is replaced. Alternatively, the position of the control valve core assembly 605 in the first chamber 603 can be adjusted to connect the first chamber 603 and the second chamber 604 to achieve external circulation, ensuring that the water path between the main inlet 601 and the main outlet 602 is connected, so that external water can enter the water purification component 100 from the main inlet 601 for filtration, and then flow out from the main outlet 602.

[0114] It should be noted that the main inlet 601 and the main outlet 602 do not limit the specific direction of water flow. For example, the main inlet 601 can be used for both water intake and water discharge; similarly, the main outlet 602 can be used for both water intake and water discharge. The specific settings are selected according to actual usage needs.

[0115] See Figure 1 It is understandable that the connector assembly 60 is also provided with a fixing seat 70, which is used to install the water purification component 100 to the required position, and the fixing seat 70 is detachably connected to the connector assembly 60.

[0116] The connector assembly 60 and the fixed base 70 can be detachably assembled by snap-fit, or other assembly methods can be used, such as fixed connection, or the connector assembly 60 and the fixed base 70 can be integrally formed, so that the connector assembly 60 and the fixed base 70 form an integral structure.

[0117] See Figure 9 and Figure 10 Another aspect of this application provides a refrigeration device 80, including a refrigeration chamber and water-using devices, as well as the aforementioned water purification component 100; the water purification component 100 is disposed in the refrigeration chamber, and the main outlet 602 of the water purification component 100 is connected to the water-using devices.

[0118] In some embodiments of this application, the refrigeration device 80 further includes a valve assembly 804, the inlet of which is connected to the main outlet 602 of the water purification component 100, and the outlet of which is connected to at least one water-using device.

[0119] In some embodiments of this application, the water-using device includes a first ice maker 805, a second ice maker 806, and a distributor 807; the refrigeration compartment includes a refrigerator compartment 801 and a freezer compartment 802, the first ice maker 805 is located in the refrigerator compartment 801, the second ice maker 806 is located in the freezer compartment 802, and the distributor 807 is located on the door 803 of the refrigeration equipment 80.

[0120] In some applications of this application, such as Figure 10 As shown, the water purification component 100 can be installed in the cold storage compartment 801. The refrigeration equipment 80 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 801 and is connected to the main water inlet 601 of the water purification component 100. Since the water purification component 100 is located in the cold storage compartment 801, the water entering the water purification component 100 can be cooled and then filtered in the low-temperature environment of the cold storage compartment 801. The filtered, low-temperature purified water is supplied to each water-using device, allowing users to directly obtain cooled water from the distributor 807 for use.

[0121] During use, the water purification component 100 of the refrigeration equipment 80 can be connected to an external tap water pipe, i.e., an external water source. The valve component 804 can be a one-inlet-three-outlet valve, which has one liquid inlet and three liquid outlets. The liquid inlet of the valve component 804 is connected to the main water outlet 602 of the water purification component 100. Each liquid outlet of the valve component 804 is connected to the first ice maker 805, the second ice maker 806 and the distributor 807 through corresponding connecting pipes, so that the water purified by the water purification component 100 can be selectively distributed to the first ice maker 805, the second ice maker 806 and the distributor 807 of the refrigeration equipment 80.

[0122] The purified water output by the water purification component 100 can be controlled and distributed to the first ice maker 805, the second ice maker 806 and the distributor 807 through a one-in-three-out valve, which can meet the ice-making needs of the first ice maker 805 and the second ice maker 806. Users can also take ice water through the distributor 807 without opening the door 803, making it more convenient to use.

[0123] Furthermore, by incorporating a water storage chamber 501 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 for water-using devices. This simplified water supply path not only extends the internal water flow path, facilitating first-in-first-out water flow, but the water storage chamber 501 also stores water. After the water purification component 100 is installed within a refrigerated compartment, the water storage chamber 501 utilizes the refrigerated compartment's temperature to cool the internal water. This cooled water is then supplied to the distributor 807, enhancing the user experience.

[0124] 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.
