Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and more specifically, to a bypass base, a water purification component, and a refrigeration device. Background Technology

[0002] In related technologies, after the bypass seat is installed on the filter, it can connect with the filter to achieve liquid filtration. However, when the filter is removed, the inlet and outlet of the bypass seat are disconnected, making the water system unconnected and causing the water supply system of the refrigeration equipment to be unusable. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] Therefore, a first aspect of the present invention provides a bypass seat.

[0005] A second aspect of the present invention also provides a water purification component.

[0006] A third aspect of the present invention also provides a refrigeration device.

[0007] In view of this, a first aspect of the present invention provides a bypass seat for a water purification assembly, the water purification assembly including a filter, the bypass seat comprising: a seat having a first inlet and a first outlet; a switching member disposed within the seat and rotatable between a first position and a second position within the seat, the switching member having a first channel for communicating with the filter; when the switching member is in the first position, the outer surface of the switching member and the inner wall of the seat form a second channel, the first inlet communicating with the first outlet through the second channel; when the switching member is in the second position, the first channel communicating with the first inlet and the first outlet.

[0008] The bypass seat provided by this invention includes a seat body and a switching component. The seat body has a first inlet and a first outlet, and the switching component has a first channel. The switching component is disposed within the seat body and rotatably connected to the seat body to switch the path connected between the first inlet and the first outlet. Specifically, when the switching component is in the second position, one end of the first channel is connected to the first inlet, and the first outlet is connected to the other end of the first channel. Simultaneously, the first channel connects to a filter, allowing liquid to flow from the first inlet into one end of the first channel, through the first channel into the filter, and then through the filter to the first outlet, thus achieving liquid filtration and improving water quality. When the switching component is in the first position, the first channel on the switching component cannot connect the first inlet and the first outlet, preventing liquid flowing into the first inlet from flowing into the first channel, thereby preventing leakage from the first channel when the filter is removed. Furthermore, the outer surface of the switching component and the inner wall of the seat body enclose a second channel, through which the first inlet connects to the first outlet, ensuring that liquid can still be transported and maintaining unobstructed water flow. The bypass seat proposed in this application achieves the switching of the communication channel between the first inlet and the first outlet through the movement of the switching component. This not only achieves liquid purification but also ensures unobstructed water flow. Furthermore, the connection between the first inlet and the first outlet is achieved through the outer surface of the switching component, eliminating the need for a through channel on the switching component. This simplifies the manufacturing difficulty of the switching component, facilitates mold forming, and reduces manufacturing costs. Moreover, the switching of the communication channel can be achieved simply by rotating the switching component, without the need for additional movement space for the switching component, thus improving the space utilization rate inside the seat.

[0009] The bypass seat provided by the present invention may also have the following additional technical features:

[0010] In some embodiments, optionally, the surface of the switching member is provided with a first sink groove and at least two second sink grooves, the at least two second sink grooves are arranged circumferentially spaced along the switching member, and the first sink groove is located at one end of the at least two second sink grooves and communicates with the at least two second sink grooves along the axis of rotation of the switching member; when the switching member is in the first position, the at least two second sink grooves are respectively arranged opposite to the first water inlet and the first water outlet, and the first sink groove, the second sink grooves and the inner wall surface of the seat form a second channel; when the switching member is in the second position, the at least two second sink grooves are respectively offset from the first water inlet and the first water outlet along the circumferential direction of the switching member.

[0011] In this embodiment, the surface of the switching component is provided with a first settling groove and at least two second settling grooves. The at least two second settling grooves are spaced apart along the circumferential direction of the switching component's rotation. The first settling groove is located at one end of the at least two second settling grooves along the axial direction, thereby achieving communication between the at least two second settling grooves. When the switching component is in the first position, the first settling groove, the at least two second settling grooves, and the inner surface of the base form a second channel. The at least two second settling grooves are respectively positioned opposite to the first inlet and the first outlet, thereby enabling the at least two second settling grooves to communicate with the first inlet and the first outlet respectively. In this way, the liquid flowing into the first inlet can flow into the second channel through the second settling groove corresponding to the first inlet, and then flow to the second settling groove corresponding to the first outlet through the communication of the first settling groove, and then flow out of the base through the first outlet, so as to ensure unobstructed water flow when the filter is disassembled. The bypass seat proposed in this application has a first sink and a second sink on the surface of the switching component, which realizes the connection between the first water inlet and the first water outlet. This ensures that when the filter is disassembled, the liquid does not pass through any space inside the switching component. For the switching component, this reduces the processing difficulty and manufacturing cost.

[0012] In some embodiments, optionally, when the switching member is in the second position, the end of the first channel connected to the first inlet and the end of the first channel connected to the first outlet are arranged opposite to each other along the first direction of the switching member, and at least two second settling tanks are arranged opposite to each other along the second direction of the switching member, with the first direction intersecting the second direction.

[0013] In this embodiment, when the switching component is in the second position, the end of the first channel connected to the first inlet and the end of the first channel connected to the first outlet are arranged opposite to each other along the first direction, and at least two second sinks are arranged opposite to each other along the second direction, so that the two ports of the first channel connecting the first inlet and the first outlet are interspersed with the at least two sinks, thereby realizing the switching of the connecting channel between the first inlet and the first outlet during the rotation of the switching component.

[0014] In some embodiments, the first sink is optionally arranged in a ring around the circumference of the switching member.

[0015] In this embodiment, the first settling tank is circumferentially annular along the switching member, thereby allowing water to pass through the entire periphery of the first settling tank along the switching member, increasing the liquid flow rate and liquid volume when the switching member is in the first position.

[0016] In some embodiments, the bypass seat may optionally include: a first sealing ring disposed on the outer wall of the switching member, along the axial direction, the first sealing ring being located at the end of the second recess away from the first recess and sealingly connected to the inner wall surface of the seat.

[0017] In this embodiment, the bypass seat also includes a first sealing ring, which is disposed on the outer wall of the switching member. The first sealing ring is located at the end of the second settling tank away from the first settling tank. The first sealing ring and the seat form a sealing connection, thereby preventing liquid leakage from the gap between the switching member and the seat when the switching member is in the first position, and ensuring the sealing of the water flow path.

[0018] In some embodiments, the bypass seat may optionally include: at least two second sealing rings, respectively disposed at both ends of the first channel; when the switching member is in the first position, the second sealing rings contact the inner wall surface of the seat to seal the first channel; when the switching member is in the second position, at least one second sealing ring is located at the connection between the first channel and the first inlet, and at least one second sealing ring is located at the connection between the first channel and the first outlet.

[0019] In this embodiment, the bypass seat also includes at least two second sealing rings, which are respectively disposed at both ends of the first channel. When the switching member is in the first position, one end of the first channel is offset from the first inlet, and the other end of the first channel is offset from the first outlet. The second sealing rings contact the inner wall surface of the seat, sealing the gap between the two ends of the first channel and the seat, preventing liquid from flowing into the first channel through the gap and causing leakage. When the switching member is in the second position, one end of the first channel is connected to the first inlet through the second sealing ring, sealing the connection between the first channel and the first inlet, preventing leakage at the connection; the other end of the first channel is connected to the first outlet through the second sealing ring, sealing the connection between the other end of the first channel and the first outlet, preventing leakage at the connection.

[0020] In some embodiments, optionally, the switching component includes: a switching column, a first channel having a connected second inlet and a second outlet, a connected third inlet and a third outlet, both the second inlet and the second outlet being located on the side wall of the switching column, the third inlet being located at one end of the switching column, the third outlet being located on the side wall of the switching column, and a filter being able to be connected between the second outlet and the third inlet; a connecting shell surrounding the end of the switching column where the third inlet is located, a portion of the filter being able to extend into the connecting shell and communicate with the third inlet; when the switching component is in the second position, the second inlet is connected to the first inlet, and the third outlet is connected to the first outlet.

[0021] In this embodiment, the switching component includes a switching column and a connecting shell. The first channel includes a second inlet, a second outlet, a third inlet, and a third outlet. The second inlet and the second outlet are both located on the side wall of the switching column and are connected. The third inlet is located at one end of the switching column, and the third outlet is located on the side wall of the switching column and is connected to the third outlet. The connecting shell surrounds the end of the switching column with the third inlet. A filter can be connected between the second outlet and the third inlet. When the switching component is in the second position, the liquid entering the base through the first inlet flows sequentially through the second inlet and the second outlet before flowing into the filter. After being filtered by the filter, the liquid flows from the third inlet to the third outlet and then out through the third outlet. Furthermore, the connecting shell surrounds the end of the switching column with the third inlet. After the filter is installed, a portion of the filter extends into the connecting shell and connects with the third inlet, facilitating the installation of a sealing structure between the connecting shell and the filter to prevent leakage at the connection between the filter and the third inlet.

[0022] In some embodiments, the bypass seat may optionally include: a fixing ring disposed within the seat body; the switching member may also include a boss disposed between the connecting shell and the switching column along the axial direction of the switching member, the fixing ring being located on the periphery of the boss, and the switching member being rotatably connected to the seat body through the fixing ring; wherein, the boss is provided with a notch that penetrates the boss along the axial direction, and when the switching member is in the second position, the second outlet is connected to the filter through the notch.

[0023] In this embodiment, the bypass seat also includes a fixing ring disposed within the seat body. The switching component also includes a boss, with the fixing ring surrounding the boss. The switching component is rotatably connected to the seat body via the fixing ring. A through-hole along the axial direction is provided on the boss, allowing liquid flowing from the second outlet to pass through the through-hole and flow to the filter, thus purifying the liquid.

[0024] According to a second aspect of the invention, a water purification assembly is also provided, comprising: a filter; and a bypass seat as described in any of the preceding claims, wherein when the switching element is in a second position, a first channel communicates with the filter so that a first inlet communicates with a first outlet through the filter.

[0025] The water purification component provided in the second aspect of the present invention, having included the bypass seat proposed in any of the above embodiments, thus possesses all the beneficial effects of the bypass seat.

[0026] In some embodiments, the filter is optionally detachably connected to the bypass seat.

[0027] In this embodiment, the filter and the bypass seat are detachably connected, so that when the filter element reaches the predetermined service time or the service life, the filter can be removed and the filter element replaced to ensure the reliability of the water purification system.

[0028] According to a third aspect of the invention, a refrigeration device is also provided, comprising: and a water purification component as described in any of the preceding claims.

[0029] The refrigeration equipment provided in the third aspect of the present invention, having all the beneficial effects of the water purification component proposed in any of the above embodiments, has all the beneficial effects of the water purification component.

[0030] In some embodiments, the refrigeration device may optionally include: a first refrigeration chamber having a water outlet; a second refrigeration chamber having an ice-making section, wherein a first water outlet is connected to the water outlet and the ice-making section for supplying water to the water outlet and the ice-making section.

[0053] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0054] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0055] The following reference Figures 1 to 17 The present invention describes a bypass seat, a water purification component, and a refrigeration device 8 according to some embodiments thereof.

[0056] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, according to an embodiment of the present invention, a bypass seat is provided, comprising: a seat 1, the seat 1 having a first inlet 10 and a first outlet 12; a switching member 2, disposed within the seat 1 and rotatable between a first position and a second position within the seat 1, the switching member 2 having a first channel 20 for connecting a filter 7; when the switching member 2 is in the first position, the outer surface of the switching member 2 and the inner wall of the seat 1 enclose a second channel 3, the first inlet 10 communicating with the first outlet 12 through the second channel 3; when the switching member 2 is in the second position, the first channel 20 connecting the first inlet 10 and the first outlet 12.

[0057] The bypass seat provided by this invention includes a seat body 1 and a switching component 2. The seat body 1 has a first water inlet 10 and a first water outlet 12. The switching component 2 has a first channel 20. The switching component 2 is disposed inside the seat body 1 and rotatably connected to the seat body 1 to realize the switching of the path connected between the first water inlet 10 and the first water outlet 12. Wherein, as... Figure 3 As shown, when the switching element 2 is in the second position, one end of the first channel 20 is connected to the first inlet 10, and the first outlet 12 is connected to the other end of the first channel 20. Simultaneously, the first channel 20 can connect to the filter 7, allowing liquid to flow from the first inlet 10 into one end of the first channel 20, through the first channel 20 into the filter 7, and then, after being filtered by the filter 7, flow from the other end of the first channel 20 to the first outlet 12, thus achieving liquid filtration and improving water quality. Figure 4 As shown, when the switching component 2 is in the first position, the first channel 20 on the switching component 2 cannot connect the first inlet 10 and the first outlet 12, so that the liquid flowing into the first inlet 10 cannot flow into the first channel 20, thereby preventing water leakage from the first channel 20 when the filter 7 is pulled out. In addition, the outer surface of the switching component 2 and the inner wall of the base 1 enclose the second channel 3, and the first inlet 10 is connected to the first outlet 12 through the second channel 3, so that the liquid can still be transported and the water path is unobstructed. The bypass seat proposed in this application achieves the switching of the communication channel between the first inlet 10 and the first outlet 12 through the movement of the switching component 2. This not only achieves liquid purification but also ensures the smooth flow of water. Furthermore, the connection between the first inlet 10 and the first outlet 12 is achieved through the outer surface of the switching component 2, eliminating the need for a through channel on the switching component 2. This simplifies the manufacturing difficulty of the switching component 2, makes the mold forming of the switching component 2 easier, and reduces manufacturing costs. Moreover, the switching of the communication channel can be achieved simply by rotating the switching component 2, eliminating the need for additional movement space for the switching component 2 and improving the space utilization rate inside the seat 1.

[0058] Optionally, the switching element 2 rotates about its own axis of rotation.

[0059] It is understandable that the filter 7 is connected between the two ends of the first channel 20, so that when the switching element 2 is in the second position, the liquid entering the first inlet 10 is filtered by the filter 7 and then flows out from the first outlet 12.

[0060] Optionally, the rotation of the switching element 2 can be achieved by driving the drive element, by manual operation by the user, or by removing or installing the filter 7 to drive the rotation of the switching element 2.

[0061] like Figure 5 and Figure 6As shown, in some embodiments, optionally, the surface of the switching member 2 is provided with a first sink 21 and at least two second sinks 22, the at least two second sinks 22 are spaced apart along the circumference of the switching member 2, and along the axis of rotation of the switching member 2, the first sink 21 is located at one end of the at least two second sinks 22 and is connected to the at least two second sinks 22; when the switching member 2 is in the first position, the at least two second sinks 22 are respectively arranged opposite to the first inlet 10 and the first outlet 12, and the first sink 21, the second sink 22 and the inner wall of the seat 1 enclose the second channel 3; when the switching member 2 is in the second position, the at least two second sinks 22 are respectively misaligned with the first inlet 10 and the first outlet 12 along the circumference of the switching member 2.

[0062] In this embodiment, the surface of the switching member 2 is provided with a first sink 21 and at least two second sinks 22. The at least two second sinks 22 are spaced apart along the circumferential direction of the rotation of the switching member 2. The first sink 21 is provided at one end of the at least two second sinks 22 along the axial direction, thereby realizing the connection of the at least two second sinks 22. When the switching component 2 is in the first position, the first settling tank 21, at least two second settling tanks 22, and the inner surface of the base 1 enclose the second channel 3. The at least two second settling tanks 22 are respectively arranged opposite to the first inlet 10 and the first outlet 12, so that the at least two second settling tanks 22 can be connected to the first inlet 10 and the first outlet 12 respectively. In this way, the liquid flowing into the first inlet 10 can flow into the second channel 3 through the second settling tank 22 corresponding to the first inlet 10, and then flow to the second settling tank 22 corresponding to the first outlet 12 through the connection of the first settling tank 21, and then flow out of the base 1 through the first outlet 12, so as to ensure the smooth flow of water when the filter 7 is removed. The bypass seat proposed in this application has a first sink 21 and a second sink 22 on the surface of the switching component 2, which realizes the connection between the first inlet 10 and the first outlet 12. This ensures that when the filter 7 is disassembled, the liquid does not pass through any space inside the switching component 2. This reduces the processing difficulty of the switching component 2 and lowers the manufacturing cost of the switching component 2.

[0063] In some embodiments, optionally, when the switching member 2 is in the second position, the end of the first channel 20 connected to the first inlet 10 and the end of the first channel 20 connected to the first outlet 12 are arranged opposite to each other along the first direction of the switching member 2, and at least two second sinks 22 are arranged opposite to each other along the second direction of the switching member 2, with the first direction intersecting the second direction.

[0064] In this embodiment, when the switching element 2 is in the second position, the end of the first channel 20 connected to the first inlet 10 and the end of the first channel 20 connected to the first outlet 12 are arranged opposite to each other along the first direction, and at least two second sinks 22 are arranged opposite to each other along the second direction, so that the two ports of the first channel 20 connecting the first inlet 10 and the first outlet 12 are interspersed with the at least two sinks, thereby realizing the switching of the connecting channel between the first inlet 10 and the first outlet 12 during the rotation of the switching element 2.

[0065] Optionally, the first direction of the switching element 2 is perpendicular to the second direction of the switching element 2. In this way, when the switching element 2 is in the first position, the switching element 2 can be rotated 90° to switch to the second position, and when the switching element 2 is in the second position, it can be rotated 90° in the opposite direction to switch to the first position.

[0066] In some embodiments, the first sink 21 is optionally arranged in a ring shape along the circumference of the switching member 2.

[0067] In this embodiment, the first settling tank 21 is annular along the circumference of the switching member 2, thereby allowing water to pass through the first settling tank 21 around the circumference of the switching member 2, increasing the liquid flow rate and liquid volume when the switching member 2 is in the first position.

[0068] like Figure 2 and Figure 7 As shown, in some embodiments, the bypass seat may optionally include a first sealing ring 4, disposed on the outer wall of the switching member 2, along the axial direction, the first sealing ring 4 is located at the end of the second recess 22 away from the first recess 21 and is sealed to the inner wall surface of the seat 1.

[0069] In this embodiment, the bypass seat also includes a first sealing ring 4, which is disposed on the outer side wall of the switching member 2. The first sealing ring 4 is located at the end of the second sink 22 away from the first sink 21. The first sealing ring 4 and the seat 1 form a sealed connection, thereby preventing liquid leakage from the gap between the switching member 2 and the seat 1 when the switching member 2 is in the first position, and ensuring the sealing of the water flow path.

[0070] Optionally, the first sealing ring 4 may include a rubber ring, a silicone ring, or other structures with sealing properties.

[0071] Optionally, the first settling tank 21 is located at the end of the second settling tank 22 away from the filter 7.

[0072] like Figure 2 and Figure 7As shown, in some embodiments, optionally, the bypass seat further includes: at least two second sealing rings 5, respectively disposed at both ends of the first channel 20; when the switching member 2 is in the first position, the second sealing rings 5 ​​contact the inner wall surface of the seat 1 to seal the first channel 20; when the switching member 2 is in the second position, at least one second sealing ring 5 is located at the connection between the first channel 20 and the first inlet 10, and at least one second sealing ring 5 is located at the connection between the first channel 20 and the first outlet 12.

[0073] In this embodiment, the bypass seat also includes at least two second sealing rings 5, which are respectively disposed at both ends of the first channel 20. When the switching member 2 is in the first position, one end of the first channel 20 is misaligned with the first inlet 10, and the other end of the first channel 20 is misaligned with the first outlet 12. The second sealing rings 5 ​​are in contact with the inner wall surface of the seat 1, so that the gap between the two ends of the first channel 20 and the seat 1 is sealed, preventing liquid from flowing into the first channel 20 through the gap between the two and causing leakage. When the switching element 2 is in the second position, one end of the first channel 20 is connected to the first inlet 10 through the second sealing ring 5. The second sealing ring 5 seals the connection between the first channel 20 and the first inlet 10, preventing leakage at the connection. The other end of the first channel 20 is connected to the first outlet 12 through the second sealing ring 5. The second sealing ring 5 seals the connection between the other end of the first channel 20 and the first outlet 12, preventing leakage at the connection.

[0074] Optionally, the second sealing ring 5 may include a silicone ring, a rubber ring, or other structures with a sealing function.

[0075] like Figure 5 and Figure 6 As shown, in some embodiments, optionally, the switching component 2 includes: a switching column 23, a first channel 20 having a connected second inlet 202 and a second outlet 204, a connected third inlet 206 and a third outlet 208, the second inlet 202 and the second outlet 204 being located on the side wall of the switching column 23, the third inlet 206 being located at one end of the switching column 23, the third outlet 208 being located on the side wall of the switching column 23, and a filter 7 being able to be connected between the second outlet 204 and the third inlet 206; a connecting shell 24 surrounding the end of the switching column 23 where the third inlet 206 is located, a portion of the filter 7 being able to extend into the connecting shell 24 and communicate with the third inlet 206; when the switching component 2 is in the second position, the second inlet 202 is connected to the first inlet 10, and the third outlet 208 is connected to the first outlet 12.

[0076] In this embodiment, the switching component 2 includes a switching column 23 and a connecting shell 24. The first channel 20 includes a second inlet 202, a second outlet 204, a third inlet 206, and a third outlet 208. The second inlet 202 and the second outlet 204 are both disposed on the side wall of the switching column 23 and are connected to each other. The third inlet 206 is disposed at one end of the switching column 23, and the third outlet 208 is disposed on the side wall of the switching column 23, and the third inlet 206 and the third outlet 208 are connected to each other. The connecting shell 24 surrounds the end of the switching column 23 where the third inlet 206 is located. The filter 7 can be connected between the second outlet 204 and the third inlet 206. When the switching element 2 is in the second position, the liquid entering the base 1 through the first inlet 10 flows sequentially through the second inlet 202 and the second outlet 204 before flowing into the filter 7. After being filtered by the filter 7, the liquid flows from the third inlet 206 to the third outlet 208 and then out through the third outlet 208. Furthermore, after the filter 7 is installed, a portion of the connecting shell 24 extends into the connecting shell 24 and communicates with the third inlet 206, facilitating the establishment of a sealing structure between the connecting shell 24 and the filter 7 to prevent leakage at the connection point.

[0077] It is understandable that the first settling tank 21 and the second settling tank 22 are also set on the switching column 23. In the assembled state, the end of the first channel 20 connected to the first inlet 10 is also the second inlet 202, and the end of the first channel 20 connected to the first outlet 12 is also the third outlet 208.

[0078] Optionally, one second sealing ring 5 is disposed at the second inlet 202, and another second sealing ring 5 is disposed at the third outlet 208.

[0079] like Figure 2 As shown, in some embodiments, optionally, the bypass seat also includes: a fixing ring 6, disposed inside the seat 1; the switching member 2 also includes a boss 25, which is disposed between the connecting shell 24 and the switching column 23 along the axial direction of the switching member 2, and the fixing ring 6 is located on the periphery of the boss 25. The switching member 2 is rotatably connected to the seat 1 through the fixing ring 6; wherein, the boss 25 is provided with a notch 250, which penetrates the boss 25 along the axial direction. When the switching member 2 is in the second position, the second outlet 204 is connected to the filter 7 through the notch 250.

[0080] In this embodiment, the bypass seat also includes a fixing ring 6, which is disposed inside the seat 1. The switching component 2 also includes a boss 25, with the fixing ring 6 surrounding the boss 25. Thus, the switching component 2 is rotatably connected to the seat 1 through the fixing ring 6. A notch 250 is provided on the boss 25, extending along the axial direction, allowing the liquid flowing from the second outlet 204 to flow through the notch 250 to the filter 7, thereby purifying the liquid.

[0081] like Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, according to one embodiment of the present invention, a water purification component is also provided, comprising: a filter 7; and a bypass seat as described in any of the above claims, wherein when the switching member 2 is in the second position, the first channel 20 is connected to the filter 7 so that the first inlet 10 is connected to the first outlet 12 through the filter 7.

[0082] The water purification component provided by the present invention, because it includes the bypass seat proposed in any of the above embodiments, has all the beneficial effects of the bypass seat.

[0083] Specifically, such as Figure 3 , Figure 12 and Figure 13 As shown, when the switching element 2 is in the second position, one end of the first channel 20 is connected to the first inlet 10, and the first outlet 12 is connected to the other end of the first channel 20. Simultaneously, the first channel 20 can connect to the filter 7. Liquid flows from the first inlet 10 into one end of the first channel 20, then through the first channel 20 into the filter 7. After being filtered by the filter 7, the liquid flows from the other end of the first channel 20 to the first outlet 12, thus achieving liquid filtration and improving water quality (water flow direction as shown). Figure 12 (As indicated by the arrow direction); such as Figure 4 As shown, when the switching element 2 is in the first position, the first channel 20 on the switching element 2 cannot connect the first inlet 10 and the first outlet 12, so that the liquid flowing into the first inlet 10 cannot flow into the first channel 20, thereby preventing water leakage from the first channel 20 when the filter 7 is pulled out. Furthermore, the outer surface of the switching element 2 and the inner wall of the base 1 enclose a second channel 3, through which the first inlet 10 is connected to the first outlet 12 (the water flow direction is as follows). Figure 4 (As indicated by the arrow), this allows the liquid to still be transported, ensuring the smooth flow of the waterway.

[0084] In some embodiments, the filter 7 is optionally detachably connected to the bypass seat.

[0085] In this embodiment, the filter 7 is detachably connected to the bypass seat, so that when the filter element 72 of the filter 7 reaches the predetermined service time or the service life, the filter 7 can be removed and the filter element 72 can be replaced to ensure the reliability of the water purification system.

[0086] Optionally, the filter 7 is detachably connected to the base 1, allowing the filter 7 to have an assembled state and a disassembled state. During the switching between the assembled and disassembled states, the filter 7 can engage with the switching element 2 to limit its movement, thereby causing the switching element 2 to rotate between a first position and a second position. During the assembly of the filter 7, the filter 7 causes the switching element 2 to rotate to the second position. During the disassembly of the filter 7, the filter 7 moves relative to the base 1, thereby causing the switching element 2 to switch to the first position.

[0087] For example, the switching component 2 is provided with a first limiting part 26, and the filter 7 is provided with a second limiting part 78. During the process of switching between the assembled state and the disassembled state of the filter 7, the first limiting part 26 and the second limiting part 78 can cooperate to limit the filter 7 so that the filter 7 drives the switching component 2 to rotate between the first position and the second position.

[0088] In this embodiment, the switching component 2 is provided with a first limiting part 26, and the filter 7 is provided with a second limiting part 78. During the process of assembling and disassembling the filter 7 and the base 1, the first limiting part 26 and the second limiting part 78 cooperate to limit the switching component 2 to rotate between the first position and the second position, thereby realizing the switching of the liquid flow channel.

[0089] Optionally, when the filter 7 includes a bottle body 70, a filter element 72, and a water stop 74, a second limiting part 78 is provided on the bottle body 70 or the water stop 74.

[0090] like Figure 12 , Figure 13 and Figure 14 As shown, in some embodiments, optionally, the filter 7 includes: a bottle body 70 with an opening, the bottle body 70 being detachably connected to the base 1; a filter element 72 disposed inside the bottle body 70; a water-stopping element 74 disposed at the opening, forming a water-stopping gap 76 between itself and the inner wall of the opening, the water-stopping element 74 having a third channel 740, the water-stopping gap 76 being connected to the third channel 740 through the filter element 72; when the filter 7 is connected to the base 1 and the switching element 2 is in the second position, the second outlet 204 of the first channel 20 is connected to the water-stopping gap 76, and the third inlet 206 of the first channel 20 is connected to the third channel 740; when the filter 7 is separated from the base 1, a water film can be formed inside the water-stopping gap 76.

[0091] In this embodiment, the filter 7 includes a bottle body 70, a filter element 72, and a water-stopping element 74. The filter element 72 is disposed inside the bottle body 70 for filtering liquid. The water-stopping element 74 is disposed inside the bottle body 70 and located at one end of the filter element 72. The water-stopping element 74 and the inner wall of the opening form a water-stopping gap 76. At the same time, the water-stopping element 74 is provided with a third channel 740. When the filter 7 is connected to the base 1, the liquid flowing into the base 1 through the first inlet 10 passes through the second inlet 202, the second outlet 204, and the water-stopping gap 76 in sequence and enters the bottle body 70. After being filtered by the filter element 72, it flows from the third channel 740 to the third inlet 206, and then from the third outlet 208 to the first outlet 12, thus achieving liquid purification. When the filter 7 is separated from the base 1, the water in the water-stop gap 76 forms a water film due to surface tension, thereby preventing external air from entering the bottle 70 and preventing the liquid in the bottle 70 from flowing out, thus reducing the amount of water dripping when replacing the filter 7.

[0092] Optionally, the width of the water-stop gap 76 is greater than 0 mm and less than or equal to 1 mm, so as to ensure that water can form a water film in the water-stop gap 76 due to tension, thereby avoiding the failure of the water-stop.

[0093] Optionally, to avoid the increase of the water-stop gap 76 due to local shrinkage during the injection molding process, a reinforcing rib 741 is provided on the water-stop component 74.

[0094] Specifically, such as Figure 15 As shown, the water-stopping component 74 is an injection-molded part. A cavity is provided between the outer wall of the injection-molded part and the third channel 740, surrounding at least a portion of the circumference of the third channel 740. Reinforcing ribs 741 are provided within the cavity. This design reduces material usage through the cavity and enhances the structural strength of the injection-molded part through the reinforcing ribs 741. This prevents excessive shrinkage during the molding process due to excessive material usage, excessive thickness, or low structural strength, thus avoiding an excessively large water-stopping gap 76. This ensures the dimensions of the water-stopping gap 76 and improves the reliability of its water-stopping function.

[0095] Optionally, the water-stopping component 74 includes: a cover 743, disposed inside the bottle body 70 and positioned within the bottle body 70, the cover 743 being located at the end of the filter element 72 near the opening, and a gap between the cover 743 and the bottle body 70, the gap communicating with the water-stopping gap 76; a water-stopping portion 744, disposed on the cover 743 and protruding from the side of the cover 743 near the opening, the outer wall of the water-stopping portion 744 enclosing the water-stopping gap 76 between the outer wall of the water-stopping portion 744 and the bottle body 70; a connecting portion 745, disposed at the end of the water-stopping portion 744 near the opening, a third channel 740 penetrating the water-stopping portion 744, the connecting portion 745 and the cover 743, the connecting portion 745 enclosing an installation cavity between the connecting portion 745 and the bottle body 70, the installation cavity communicating with the water-stopping gap 76; in the assembled state, a portion of the switching component 2 extends into the installation cavity.

[0096] In this embodiment, the water-stopping component 74 includes a cover 743, a water-stopping part 744 and a connecting part 745 disposed on the cover 743. The water-stopping part 744 is disposed on the cover 743 and protrudes from the side of the cover 743 near the opening. The connecting part 745 is disposed on the side of the water-stopping part 744 near the opening. A water-stopping gap 76 is formed between the outer wall of the water-stopping part 744 and the inner wall of the bottle 70. An installation cavity is formed between the connecting part 745 and the bottle 70. When the filter 7 is installed on the base 1, a part of the switching component 2 is inserted into the installation cavity, so that the first water inlet 10 communicates with the filter part through the water-stopping gap 76, and the third channel 740 communicates with the third water inlet 206. This allows the liquid flowing into the first water inlet 10 to flow through the filter part and then out through the first water outlet 12, achieving the effect of liquid filtration. After the filter 7 is removed, the water-stopping gap 76 can stop the filter 7 from leaking, preventing leakage from the bottle 70. Meanwhile, there is a gap between the cap 743 and the bottle 70, which allows the liquid flowing into the water-stop gap 76 to flow through the gap to the filter section, thereby achieving liquid filtration. Furthermore, the cap 743 and the bottle 70 are matched in a limiting manner, which can fix the position of the water-stop component 74, thereby ensuring the reliability of the water-stop gap 76.

[0097] Optionally, such as Figure 16 As shown, a slit 742 is provided on the water-stopping part 744. The slit 742 penetrates the water-stopping part 744 along the axial direction of the switching part 2. The slit 742 is connected to the water-stopping gap 76 to increase the water passage area and reduce the risk of blockage.

[0098] Optionally, when the filter 7 is connected to the base 1, the third channel 740 extends into the connecting shell 24 and communicates with the third inlet 206.

[0099] like Figure 17 As shown, according to one embodiment of the present invention, a refrigeration device 8 is also provided, comprising: and a water purification component as described in any of the above claims.

[0100] The refrigeration device 8 provided by the present invention, because it includes the water purification component proposed in any of the above embodiments, has all the beneficial effects of the water purification component.

[0101] like Figure 17 As shown, in some embodiments, optionally, the refrigeration device 8 further includes: a first refrigeration chamber 80, the first refrigeration chamber 80 having a water outlet 800; a second refrigeration chamber 82, the second refrigeration chamber 82 having an ice-making section 820, and a first water outlet 12 communicating with the water outlet 800 and the ice-making section 820 for supplying water to the water outlet 800 and the ice-making section 820.

[0102] In this embodiment, the refrigeration device 8 further includes a first refrigeration chamber 80 and a second refrigeration chamber 82. The first refrigeration chamber 80 is provided with a water outlet 800, and the second refrigeration chamber 82 is provided with an ice-making section 820. The first water outlet 12 is connected to the water outlet 800 and the ice-making section 820 respectively, so that liquid flows to the water outlet 800 and the ice-making section 820 respectively, thereby realizing the preparation of cold water and ice.

[0103] Optionally, the first refrigeration compartment 80 includes a refrigerator compartment, and the second refrigeration compartment 82 includes a freezer compartment.

[0104] Optionally, the refrigeration equipment 8 also includes a valve body located at the first water outlet 12, used to switch the communication direction of the first water outlet 12 so that the first water outlet 12 is connected to the water outlet section 800, and / or the first water outlet 12 is connected to the ice making section 820.

[0105] Specifically, the first inlet 10 is connected to the water supply unit, for example, to an external faucet or to a water tank assembly. When the filter 7 is installed on the base 1, the liquid flows from the first inlet 10 to the filter 7, and after being filtered by the filter 7, it flows out from the first outlet 12, and then flows to the outlet 800 and / or the ice-making unit 820 under the switching of the valve body.

[0106] Optionally, the refrigeration equipment 8 includes refrigerators, freezers, etc.

[0107] In practical applications, the water purification component includes a mounting base, a connector (e.g., a bypass base), and a water purification module (e.g., a filter 7). The water purification module is connected to the connector by a rotating installation method.

[0108] The connector consists of a connector body (e.g., seat 1), a rotating center rod, a welding fixing ring (e.g., fixing ring 6), an inlet connector, an outlet connector, and several sealing rings, and the components are assembled using ultrasonic welding. The water purification module consists of an upper end cap (e.g., water stop 74), filter media (e.g., filter element 72), a lower end cap, a filter bottle (e.g., bottle body 70), and a tail. Optionally, the water purification module also includes a handle. The filter bottle and tail are assembled by rotary welding.

[0109] The inlet connector (e.g., the first inlet 10) and outlet connector (e.g., the first outlet 12) of the connector are connected to the inlet pipe and outlet pipe, respectively. When not installed with the filter 7, the inlet and outlet ports of the rotating center rod (e.g., the second inlet 202 and the third outlet 208) are offset from the inlet and outlet ports of the connector body (e.g., the first inlet 10 and the first outlet 12) at an angle, and the sealing ring (e.g., the second sealing ring 5) seals the inlet and outlet ports of the rotating center rod against the inner wall of the connector body, preventing water from flowing into the rotating center rod. At this time, the water flowing into the connector from the inlet connector flows into the outlet connector through the structural steps and gaps (e.g., the first settling tank 21 and the second settling tank 22) between the rotating center rod and the connector body, forming a water flow path.

[0110] When the water purification module is assembled with the connector, the long arm at the bottom of the rotating center rod extends into the corresponding notch structure of the upper cover. As the water purification module and connector are rotated and fastened, because the upper cover and water purification module are fixedly connected, the water purification module will cause the rotating center rod inside the connector to rotate at a certain angle, thus connecting the inlet and outlet of the rotating center rod with the inlet and outlet of the connector. The rotation angle of the rotating center rod can be adjusted by changing the width of the notch structure and the width of the long arm at the bottom of the rotating center rod, allowing for designs where the rotation angle of the rotating center rod and the water purification module are the same or different.

[0111] When the water purification module reaches the end of its service life or is disassembled midway, the notch structure of the upper end cover causes the long arm at the bottom of the rotating center rod to rotate in the opposite direction by the same angle, thereby restoring the rotating center rod to the position that forms the bypass channel.

[0112] Alternatively, regarding the implementation of the rotation of the rotating center rod, the long arm at the bottom of the rotating center rod can extend into a specific structure at the mouth of the filter bottle, and the filter 7 can drive the rotating center rod to rotate during disassembly and assembly through the limiting cooperation between the two.

[0113] Optionally, the upper end cap is assembled with the filter bottle, and the assembly gap between the upper end cap and the filter bottle (e.g., water-stop gap 76) is controlled within 1mm, so that when the water purification module is removed, water forms a water film in the narrow gap due to the surface tension of the water.

[0114] Optionally, to avoid the problem of excessively large local dimensions of the water-stop gap 76 due to local shrinkage during the injection molding process, causing water-stop failure, the upper end cap can be reinforced.

[0115] Optionally, such as Figure 16 As shown, in addition to controlling the assembly gap between the upper end cap and the filter bottle to be within 1mm, a slit with a gap of less than 1mm (e.g., slit 742) can also be designed on the upper end cap. This increases the water flow area and makes it less prone to clogging during actual use.

[0116] Optionally, to accommodate both refrigerator compartment and horizontal installation scenarios, a detachable handle is designed at the rear of filter 7. When filter 7 is installed on the top or door of the refrigerator compartment, filter 7 rotates to install with the mounting bracket. In this case, simply grasp the rear of the filter 7; no handle is needed. When filter 7 is installed horizontally, the user has no other contact points. In this scenario, filter 7 is equipped with a handle, which is used for installation and removal. Optionally, the handle can be attached to the rear of filter 7 via snap-fit, sleeve, or welding, enabling lean manufacturing and minimizing material changes to achieve differentiated usage scenarios.

[0117] The water purification component proposed in this application achieves the switching from the bypass channel to the purification channel by rotating the central rod during the installation process of the water purification module, without the need for additional operation, saving time and effort.

[0118] Optionally, the long arm is on the rotating central rod, and the notch structure is set on the water purification module; their positions can also be interchanged. Meanwhile, the number of engagement points between the rotating central rod and the water purification module should be no less than one.

[0119] Alternatively, the notch structure can also be a groove, etc.

[0120] In this invention, the term "multiple" refers to two or more unless otherwise explicitly defined. The terms "installed," "connected," "linked," and "fixed," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; "linked" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0121] In the description of this specification, the terms "one embodiment," "some embodiments," "specific embodiment," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
