Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a water purification component and a refrigeration device. Background Art

[0002] In the related art, when the filter of the water purification component is installed on the connecting seat, the filter is connected to the water path in the connecting seat, thereby realizing the filtration of the liquid; when the filter is removed, the water inlet and outlet of the connecting seat are disconnected, so that the water path of the connecting seat cannot be connected. If the water path of the connecting seat is to be connected, a matching plug is required, which makes the switching of the water path of the connecting seat time-consuming and laborious. 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] To this end, a first aspect of the present invention provides a water purification component.

[0005] A second aspect of the present invention further provides a refrigeration device.

[0006] In view of this, the first aspect of the present invention proposes a water purification component, including a connecting seat, provided with a water inlet and a water outlet; a rotating rod, which is arranged in the connecting seat and can rotate in the connecting seat, and the rotating rod is provided with a purification channel and a first limiting portion; a filter, including a bottle body, an end cover and a filter element, the bottle body is provided with an opening, the filter element is arranged in the bottle body, the end cover is arranged in the bottle body and is located at an end of the filter element close to the opening, at least one of the side wall of the end cover and the side wall of the bottle body is provided with a second limiting portion, the filter is detachably connected to the connecting seat, and during the process of connecting or disassembling the filter and the connecting seat The first limiting portion and the second limiting portion are limited and cooperated to drive the rotating rod to rotate between the first position and the second position; when the rotating rod is in the second position, the filter is separated from the connecting seat, one end of the purification channel is connected to the water inlet, and the other end is connected to the water outlet, and the filter is connected between the two ends of the purification channel; when the rotating rod is in the first position, the filter is connected to the connecting seat, the purification channel is staggered with the water inlet and the water outlet, the outer wall surface of the rotating rod and the inner wall surface of the connecting seat enclose a bypass channel, and the bypass channel connects the water inlet and the water outlet.

[0007] The water purification assembly provided by the present invention comprises a connecting seat, a rotating rod and a filter, wherein the filter comprises a bottle body, a filter element and an end cap disposed in the bottle body, wherein the end cap is disposed at one end of the filter element close to an opening, thereby preventing the filter element from moving. The connecting seat is provided with a water inlet and a water outlet, the rotating rod is provided with a purification channel, the rotating rod is disposed in the connecting seat and is rotatably connected to the connecting seat, the filter can be detachably connected to the connecting seat, and during the process of disassembling and assembling the filter relative to the connecting seat, the filter can drive the rotating rod to rotate between the first position and the second position through the limiting cooperation of the first limiting portion and the second limiting portion, so as to realize the switching of the path connected between the water inlet and the water outlet. Among them, during the process of assembling the filter, the filter drives the rotating rod to rotate to the second position. When the rotating rod is in the second position, one end of the purification channel is connected to the water inlet, the water outlet is connected to the other end of the purification channel, and the filter is connected to the purification channel, so that the liquid flowing into the connecting seat from the water inlet flows into the filter through one end of the purification channel, and then flows to the water outlet from the other end of the purification channel after being filtered by the filter, and finally flows out of the connecting seat, thereby achieving liquid filtration and improving water quality; during the process of disassembling the filter, the filter moves relative to the connecting seat, and then can drive the rotating rod to switch to the first position. When the rotating rod is in the first position, the purification channel on the rotating rod cannot connect the water inlet and the water outlet, so that the liquid flowing into the water inlet cannot flow into the purification channel, thereby avoiding leakage when the filter is pulled out, and when the rotating rod is in the first position, the outer surface of the rotating rod and the inner wall surface of the connecting seat enclose a bypass channel, and the water inlet is connected to the water outlet through the bypass channel, so that when the filter is pulled out, the liquid can still be transported, ensuring the reliability of liquid transportation. In addition, the second limiting portion is arranged on at least one of the side wall of the end cap and the side wall of the bottle body, which can not only realize the linkage between the filter and the rotating rod, but also can reduce the occupied space of the filter and the rotating rod as a whole in the axial direction through the cooperation of the first limiting portion and the side wall of the end cap or the side wall of the bottle body, thereby reducing the volume of the water purification assembly. The water purification assembly proposed in the present application can be linked to the rotating rod when the filter is disassembled, so that the movement of the rotating rod does not require the drive of other driving structures, reducing the number of parts and components, reducing the overall volume of the water purification assembly, and when the filter is disassembled, the water inlet and the water outlet are connected through the outer surface of the rotating rod, and there is no need to set a through channel on the rotating rod to realize the connection between the water inlet and the water outlet, simplifying the manufacturing difficulty of the rotating rod, making the mold forming of the rotating rod convenient, reducing the manufacturing cost, and the switching of the connecting channel can be realized by rotating the rotating rod around its own rotation axis, without the need to set an additional movement space for the rotating rod, so that the space utilization rate inside the connecting seat is improved.

[0008] The water purification component provided by the present invention may also have the following additional technical features:

[0009] In some embodiments, optionally, the second limiting portion is disposed on the outer side wall of the end cap, or the second limiting portion is disposed on the inner side wall of the bottle body.

[0010] In this embodiment, the second limiting portion is arranged on the outer side wall of the end cap to reduce the radial space occupied by the bottle body when the first limiting portion and the second limiting portion are connected. Alternatively, the second limiting portion is arranged on the inner side wall of the bottle body to avoid the connection structure outside the bottle body, and avoid interference with the relative movement between the bottle body and the connecting seat while realizing the linkage between the filter and the rotating rod. At the same time, the second limiting portion is arranged on either the end cap or the bottle body, which can reduce the processing steps and thus reduce the manufacturing cost.

[0011] In some embodiments, optionally, when both the bottle body and the end cap are provided with a second limiting portion, the inner wall of the bottle body and the outer wall of the end cap are provided with a second limiting portion, and the second limiting portion on the bottle body and the second limiting portion on the end cap are correspondingly arranged, and the first limiting portion is limitedly matched with the second limiting portion on the bottle body and the second limiting portion on the end cap.

At the same time, by limiting the first limiting part by the bottle body and the end cap at the same time, when the limiting of either one of the bottle body and the end cap fails, the rotating rod can be driven by the limiting matching of the other one with the first limiting part.

[0013] It can be understood that when the filter is connected to the connecting seat, a part of the first limiting portion cooperates with the second limiting portion on the inner wall of the bottle body, and the other part cooperates with the second limiting portion on the end cover, so that the bottle body and the end cover limit the first limiting portion at the same time. Compared with the situation where one of the bottle body and the end cover limits the first limiting portion, the resistance of the rotating rod driven by the bottle body to rotate can be distributed to the bottle body and the end cover by limiting the first limiting portion at the same time by the bottle body and the end cover, thereby increasing the connection strength between the rotating rod and the filter and reducing the risk of damage to the end cover or the bottle body.

[0062] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8As shown, according to one embodiment of the present invention, the present invention proposes a water purification component, including a connecting seat 1, provided with a water inlet 10 and a water outlet 12; a rotating rod 2, which is arranged in the connecting seat 1 and can rotate in the connecting seat 1, and the rotating rod 2 is provided with a purification channel 20 and a first limiting portion 28; a filter 3, including a bottle body 30, an end cover 32 and a filter element 31, the bottle body 30 is provided with an opening 302, the filter element 31 is arranged in the bottle body 30, the end cover 32 is arranged in the bottle body 30 and is located at one end of the filter element 31 close to the opening 302, at least one of the side walls of the end cover 32 and the side walls of the bottle body 30 is provided with a second limiting portion 36, the filter 3 is detachably connected to the connecting seat 1, and when the filter 3 is connected to the connecting seat 1 During the connection or disassembly process, the first limit portion 28 and the second limit portion 36 are limited and cooperated to drive the rotating rod 2 to rotate between the first position and the second position; when the rotating rod 2 is in the second position, the filter 3 is separated from the connecting seat 1, one end of the purification channel 20 is connected with the water inlet 10, and the other end is connected with the water outlet 12, and the filter 3 is connected between the two ends of the purification channel 20; when the rotating rod 2 is in the first position, the filter 3 is connected to the connecting seat 1, the purification channel 20 is staggered with the water inlet 10 and the water outlet 12, the outer wall surface of the rotating rod 2 and the inner wall surface of the connecting seat 1 enclose a bypass channel 14, and the bypass channel 14 connects the water inlet 10 and the water outlet 12.

[0063] The water purification component provided by the present invention includes a connecting seat 1, a rotating rod 2 and a filter 3. The filter 3 includes a bottle body 30, a filter element 31 and an end cap 32 arranged in the bottle body 30. The end cap 32 is arranged at an end of the filter element 31 close to the opening 302, thereby preventing the filter element 31 from moving. The connecting seat 1 is provided with a water inlet 10 and a water outlet 12, and the rotating rod 2 is provided with a purification channel 20. The rotating rod 2 is arranged in the connecting seat 1 and is rotatably connected to the connecting seat 1. The filter 3 can be detachably connected to the connecting seat 1, and during the process of disassembling and assembling the filter 3 relative to the connecting seat 1, the filter 3 can drive the rotating rod 2 to rotate between the first position and the second position through the limiting cooperation of the first limiting portion 28 and the second limiting portion 36, so as to realize the switching of the path connected between the water inlet 10 and the water outlet 12. In the process of assembling the filter 3, the filter 3 drives the rotating rod 2 to rotate to the second position, such as Fig.13 and Fig.14As shown, when the rotating rod 2 is in the second position, one end of the purification channel 20 is connected to the water inlet 10, the water outlet 12 is connected to the other end of the purification channel 20, and the filter 3 is connected to the purification channel 20, so that the liquid flowing into the connecting seat 1 from the water inlet 10 flows into the filter 3 through one end of the purification channel 20, and then flows to the water outlet 12 from the other end of the purification channel 20 after being filtered by the filter 3, and finally flows out of the connecting seat 1, thereby achieving the filtration of the liquid and improving the water quality; in the process of removing the filter 3, the filter 3 moves relative to the connecting seat 1, thereby driving the rotating rod 2 to switch to the first position, as shown in FIG. Fig.15 As shown, when the rotating rod 2 is in the first position, the purification channel 20 on the rotating rod 2 cannot communicate with the water inlet 10 and the water outlet 12, so that the liquid flowing into the water inlet 10 cannot flow into the purification channel 20, thereby avoiding leakage when the filter 3 is unplugged, and, when the rotating rod 2 is in the first position, the outer surface of the rotating rod 2 and the inner wall surface of the connecting seat 1 enclose a bypass channel 14, and the water inlet 10 is connected to the water outlet 12 through the bypass channel 14, so that when the filter 3 is unplugged, the liquid can still be transported, ensuring the reliability of liquid transportation. In addition, the second limiting portion 36 is arranged on at least one of the side wall of the end cap 32 and the side wall of the bottle body 30, which can not only realize the linkage between the filter 3 and the rotating rod 2, but also can reduce the space occupied by the filter 3 and the rotating rod 2 as a whole in the axial direction through the cooperation of the first limiting portion 28 and the side wall of the end cap 32 or the side wall of the bottle body 30, thereby reducing the volume of the water purification component. In the water purification assembly proposed in the present application, the assembly and disassembly of the filter 3 can be linked to the rotating rod 2, so that the movement of the rotating rod 2 does not need to be driven by other driving structures, reducing the number of parts and components and reducing the overall volume of the water purification assembly. When the filter 3 is removed, the water inlet 10 and the water outlet 12 are connected through the outer surface of the rotating rod 2, and there is no need to set a through channel on the rotating rod 2 to achieve the connection between the water inlet 10 and the water outlet 12, which simplifies the manufacturing difficulty of the rotating rod 2, makes the mold forming of the rotating rod 2 convenient, and reduces the manufacturing cost. In addition, the connecting channel can be switched by rotating the rotating rod 2 around its own rotation axis, and there is no need to set up an additional movement space for the rotating rod 2, so that the space utilization rate inside the connecting seat 1 is improved.

[0064] It is understandable that the filter 3 proposed in the present application is detachably connected to the connecting seat 1, so that the filter 3 can be replaced or repaired to ensure the reliability of the water purification component in water purification.

[0065] Optionally, during the process of assembling the filter 3, the filter 3 switches from the disassembled state to the assembled state, and at the same time the filter 3 can drive the rotating rod 2 to rotate, so that the rotating rod 2 switches from the first position to the second position; during the process of disassembling the filter 3, the filter 3 switches from the assembled state to the disassembled state, and at the same time the filter 3 can drive the rotating rod 2 to rotate, so that the rotating rod 2 switches from the second position to the first position.

[0066] Optionally, the filter 3 is rotationally matched with the connecting seat 1 .

[0067] Optionally, the filter 3 is connected between the two ends of the purification channel 20, so that the liquid can flow into the purification channel 20 from the water inlet 10, then flow to the filter 3 through the purification channel 20, and then flow to the water outlet 12 through the other end of the purification channel 20.

[0068] In some embodiments, optionally, the second limiting portion 36 is disposed on the outer side wall of the end cover 32 , or the second limiting portion 36 is disposed on the inner side wall of the bottle body 30 .

[0069] In this embodiment, if Figure 1 As shown, the second limiting portion 36 is disposed on the outer side wall of the end cap 32 to reduce the radial space occupied by the bottle body 30 when the first limiting portion 28 and the second limiting portion 36 are connected. Figure 8 As shown, the second limiter 36 is arranged on the inner side wall of the bottle body 30, which can avoid the connection structure outside the bottle body 30, and avoid interference with the relative movement between the bottle body 30 and the connecting seat 1 while realizing the linkage between the filter 3 and the rotating rod 2. At the same time, the second limiter 36 is arranged on either the end cap 32 or the bottle body 30, which can reduce the processing steps and thus reduce the manufacturing cost.

[0070] In some embodiments, optionally, when both the bottle body 30 and the end cover 32 are provided with a second limiting portion 36, the inner wall of the bottle body 30 and the outer wall of the end cover 32 are provided with a second limiting portion 36, and the second limiting portion 36 on the bottle body 30 and the second limiting portion 36 on the end cover 32 are correspondingly arranged, and the first limiting portion 28 is limitedly matched with the second limiting portion 36 on the bottle body 30 and the second limiting portion 36 on the end cover 32.

[0071] In this embodiment, when both the bottle body 30 and the end cap 32 are provided with the second limiting portion 36, the inner side wall of the bottle body 30 and the outer side wall of the end cap 32 are provided with the second limiting portion 36, and the second limiting portions 36 of the two are correspondingly arranged, so that when the first limiting portion 28 and the second limiting portion 36 are limited and matched, the first limiting portion 28 can simultaneously be limited and matched with the corresponding second limiting portion 36 on the bottle body 30 and the second limiting portion 36 on the end cap 32, thereby increasing the connection strength between the first limiting portion 28 and the filter 3, thereby ensuring the driving effect of the rotating rod 2 during the disassembly and assembly of the filter 3, so as to realize the switching of the bypass flow path and the purification flow path. At the same time, by limiting the first limiting portion 28 by the bottle body 30 and the end cap 32 at the same time, when the limiting of either of the bottle body 30 and the end cap 32 fails, the driving of the rotating rod 2 can be realized by the limiting cooperation of the other with the first limiting portion 28.

[0072] It can be understood that when the filter 3 is connected to the connecting seat 1, a part of the first limiting portion 28 is limited and cooperated with the second limiting portion 36 on the inner wall of the bottle body 30, and the other part is limited and cooperated with the second limiting portion 36 on the end cover 32, so that the bottle body 30 and the end cover 32 limit the first limiting portion 28 at the same time. Compared with the situation where one of the bottle body 30 and the end cover 32 limits the first limiting portion 28, the simultaneous limiting of the first limiting portion 28 by the bottle body 30 and the end cover 32 can distribute the resistance of the rotating rod 2 driven by the bottle body 30 to rotate to the bottle body 30 and the end cover 32, thereby increasing the connection strength between the rotating rod 2 and the filter 3 and reducing the risk of damage to the end cover 32 or the bottle body 30.

[0074] In this embodiment, the first limiting portion 28 and the second limiting portion 36 are limited by a limiting plate 280 and a limiting groove 360, wherein a notch 362 is provided at one end of the limiting groove 360 ​​along the axial direction of the rotating rod 2. When the filter 3 is installed, the limiting plate 280 can be inserted into the limiting groove 360 ​​through the notch 362, thereby realizing the rotation of the rotating rod 2 by rotating the filter 3.

[0075] Optionally, a limit plate 280 is provided on the rotating rod 2, and a limit groove 360 ​​is provided on the filter 3 or the end cover 32, so as to facilitate the storage of the filter 3 after the filter 3 is removed.

The first inlet 2020 is opposite to and connected to the water inlet 10, and the second outlet 2042 is opposite to and connected to the water outlet 12. The liquid enters the first channel 202 from the water inlet 10 and the first inlet 2020, flows into the liquid inlet channel 33 from the first outlet 2022 through the connecting cavity 16, and after being filtered by the filter element 31, flows from the liquid outlet channel 320 to the second inlet 2040, and then flows from the second outlet 2042 to the water outlet 12.

[0090] like Fig.16 and Fig.17 As shown, in some embodiments, optionally, a first groove 21 and at least two second grooves 22 are provided on the surface of the rotating rod 2, and the at least two second grooves 22 are arranged at intervals along the circumference of the rotating rod 2. Along the axial direction of the rotation of the rotating rod 2, the first groove 21 is located at one end of the at least two second grooves 22 and is connected with the at least two second grooves 22; when the rotating rod 2 is in the first position, the at least two second grooves 22 are respectively arranged opposite to the water inlet 10 and the water outlet 12, and the first groove 21, the second groove 22 and the inner wall surface of the connecting seat 1 enclose a bypass channel 14; when the rotating rod 2 is in the second position, at least two second grooves 22 are respectively staggered with the water inlet 10 and the water outlet 12 along the circumference of the rotating rod 2.

[0091] In this embodiment, the surface of the rotating rod 2 is provided with a first sink 21 and at least two second sinks 22, and the at least two second sinks 22 are arranged at intervals along the circumferential direction of the rotating rod 2, and the first sink 21 is arranged at one end of the at least two second sinks 22 along the axial direction, thereby realizing the communication of the at least two second sinks 22.

The water purification component proposed in the present application is provided with a first trough 21 and a second trough 22 on the surface of the rotating rod 2, so as to realize the connection between the water inlet 10 and the water outlet 12, so that when the filter 3 is disassembled, the liquid does not pass through any space inside the rotating rod 2. For the rotating rod 2, the processing difficulty of the rotating rod 2 is reduced, so that the manufacturing cost of the rotating rod 2 is reduced, thereby reducing the overall cost of the water purification component.

[0092] In some embodiments, optionally, the first sink groove 21 is arranged in a ring shape along the circumference of the rotating rod 2 .

[0093] In this embodiment, the first sink 21 is annular along the circumference of the rotating rod 2, so that water can flow through the first sink 21 along the circumference of the rotating rod 2, increasing the liquid flow rate and liquid flow when the rotating rod 2 is in the first position.

[0094] In some embodiments, optionally, at least two second sinks 22 are disposed on opposite sides of the rotating rod 2 .

[0095] In this embodiment, at least two second recesses 22 are disposed on opposite sides of the rotating rod 2 , so that the second recesses 22 are symmetrically disposed, which facilitates the processing of the rotating rod 2 .

The first sealing ring 4 is located at the end of the second sink groove 22 away from the first sink groove 21. A sealed connection is formed between the first sealing ring 4 and the connecting seat 1, thereby preventing the liquid flowing into the connecting seat 1 from the water inlet 10 from flowing out of the connecting seat 1 through the gap between the rotating rod 2 and the connecting seat 1, thereby ensuring the sealing of the water flow path.

[0098] Optionally, the first sealing ring 4 includes a rubber ring or a silicone ring or other structures with sealing performance.

[0099] In some embodiments, optionally, the water purification component also includes: at least two second sealing rings 5, respectively arranged at the two ends of the purification channel 20; when the rotating rod 2 is in the first position, the second sealing ring 5 contacts the inner wall surface of the connecting seat 1 to seal the purification channel 20; when the rotating rod 2 is in the second position, one end of the purification channel 20 is connected to the water inlet 10 through the second sealing ring 5, and the other end of the purification channel 20 is connected to the water outlet 12 through the second sealing ring 5.

[0100] In this embodiment, the water purification component further includes at least two second sealing rings 5, which are respectively arranged at the two ends of the purification channel 20. When the rotating rod 2 is in the first position, one end of the purification channel 20 is staggered with the water inlet 10, and the other end of the purification channel 20 is staggered with the water outlet 12. The second sealing ring 5 contacts the inner wall surface of the connecting seat 1, so that the gap between the two ends of the purification channel 20 and the connecting seat 1 is sealed, so as to prevent liquid from flowing into the purification channel 20 through the gap between the two and causing leakage. When the rotating rod 2 is in the second position, one end of the purification channel 20 is connected to the water inlet 10 via the second sealing ring 5, and the sealing of the connection between the purification channel 20 and the water inlet 10 is achieved by the second sealing ring 5, thereby avoiding leakage at the connection between one end of the purification channel 20 and the water inlet 10; the other end of the purification channel 20 is connected to the water outlet 12 via the second sealing ring 5, and the sealing of the connection between the other end of the purification channel 20 and the water outlet 12 is achieved by the second sealing ring 5, thereby avoiding leakage at the connection between the other end of the purification channel 20 and the water outlet 12.

[0101] Optionally, the second sealing ring 5 includes a silicone ring or a rubber ring or other structures with a sealing function.

[0102] like Fig. 20 As shown, in some embodiments, optionally, a handle 37 is provided on the filter 3, and the handle 37 is detachably connected to the filter 3.

[0103] In this embodiment, a detachable handle 37 is provided on the filter 3, so that the filter 3 can be adapted to different installation scenarios. For example, when the filter 3 is installed on the top or door of the refrigerator, at this time, the filter 3 can be grasped by the tail of the bottle body without the need to use the handle 37. When the filter 3 is installed horizontally, the user has no other contact position. In this scenario, the handle 37 is installed on the filter 3, and the disassembly and assembly are achieved by grasping the handle 37. The filter 3 proposed in this application can achieve lean manufacturing and realize differentiated usage scenarios with minimal material changes.

[0104] like Fig.21 As shown, according to an embodiment of the present invention, a refrigeration device 8 is also proposed, including: a water purification component as proposed in any of the above embodiments.

[0105] The refrigeration device 8 provided by the present invention comprises the water purification component proposed in any of the above embodiments, and therefore has all the beneficial effects of the water purification component.

[0106] like Fig.21 As shown, in some embodiments, optionally, the refrigeration equipment 8 also includes: a first refrigeration chamber 80, the first refrigeration chamber 80 is provided with a water outlet 800; a second refrigeration chamber 82, the second refrigeration chamber 82 is provided with an ice-making section 820, and the water outlet 12 is connected to the water outlet 800 and the ice-making section 820, and is used to supply water to the water outlet 800 and the ice-making section 820.

[0107] In this embodiment, the refrigeration equipment 8 also 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 water outlet 12 is respectively connected to the water outlet 800 and the ice-making section 820, so that the liquid flows to the water outlet 800 and the ice-making section 820, respectively, to prepare cold water and ice cubes.

[0108] Optionally, the first refrigerating chamber 80 includes a refrigerator compartment, and the second refrigerating chamber 82 includes a freezer compartment.

[0109] Optionally, the refrigeration device 8 further includes a valve body, which is disposed at the water outlet 12 and is used to switch the connection direction of the water outlet 12 so that the water outlet 12 is connected to the water outlet part 800 and / or the water outlet 12 is connected to the ice making part 820.

[0110] Optionally, the refrigeration device 8 includes a refrigerator or a freezer.

[0111] Specifically, the water inlet 10 is connected to a water supply unit, such as an external faucet or a water tank assembly. When the filter 3 is in an assembled state, liquid flows from the water inlet 10 to the filter 3, and after being filtered by the filter 3, flows out from the water outlet 12, and then flows to the water outlet 800 and / or the ice making unit 820 under the switching of the valve body.

[0112] In specific applications, such as Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 , Fig.14 and Fig.19 As shown, the water purification assembly comprises a fixing seat 7, a connection seat (including a water inlet 10 and a water outlet 12), and a water purification module (such as a filter 3). The water purification module is connected to the connection seat by a rotating installation.

[0113] The socket is composed of a socket body (e.g., a connection socket 1), a rotating center rod (e.g., a rotating rod 2), a welded fixing ring (e.g., a fixing ring 6), a water inlet joint (provided with a water inlet 10), a water outlet joint (provided with a water outlet 12), and a plurality of sealing rings, and the assembly is completed by an ultrasonic welding process. The water purification module is composed of an upper end cover (e.g., an end cover 32), a filter material (e.g., a filter element 31), a lower end cover, a bottle body 30, and a tail. Optionally, the water purification module also includes a handle 37, and the filter 3 and the tail are completed by rotation welding.

[0114] The water inlet joint and the water outlet joint of the socket are connected to the water inlet pipe and the water outlet pipe respectively. When the filter is not installed, the water inlet and outlet of the rotating center rod (such as the water inlet joint and the water outlet joint) are staggered with the water inlet and outlet of the socket body (such as the first inlet 2020 and the second outlet 2042) by an angle (optionally, this angle is 90°), and the sealing ring forms a seal between the water inlet and outlet of the rotating center rod and the inner wall of the socket body, so that water cannot flow into the rotating center rod. At this time, the water flowing into the socket from the water inlet joint flows into the water outlet joint through the structural steps and gaps between the rotating center rod and the socket body (such as the first sink 21 and the second sink 22), forming a water flow path.

[0115] When the water purification module is assembled with the socket, the long arm at the bottom of the rotating center rod (e.g., the first limit portion 28) extends into the corresponding notch structure of the upper end cover (e.g., the second limit portion 36). When the water purification module is rotated and fastened with the socket, because the upper end cover is fixedly connected to the water purification module, the water purification module will drive the rotating center rod inside the socket to rotate a certain angle, so that the water inlet and outlet of the rotating center rod are connected to the water inlet and outlet of the socket. Among them, the rotation angle of the rotating center rod can be adjusted by adjusting the width of the notch structure and the width of the long arm at the bottom of the rotating center rod, so as to realize a design in which the rotation angle of the rotating center rod is the same or different from that of the water purification module.

[0116] When the water purification module reaches the end of its service life or is disassembled midway, the notch structure of the upper end cover drives 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 where the bypass channel 14 is formed.

[0117] Optionally, regarding the implementation method of the rotation of the rotating center rod, the long arm at the bottom of the rotating center rod can also extend into a specific structure at the mouth of the filter 3, and through the limiting cooperation between the two, the filter drives the rotating center rod to rotate during disassembly and assembly.

[0118] Optionally, the upper end cap is assembled with the bottle body 30, and the width of the assembly gap (e.g., the liquid inlet channel 33) between the upper end cap and the bottle body 30 is controlled within 1 mm, so that when the water purification module is removed, water forms a water film in the slit gap due to the surface tension of the water. That is, the liquid inlet channel 33 constitutes a water-stopping slit, and when the filter 3 is removed, a water film is formed in the water-stopping slit to prevent water leakage.

[0119] Optionally, in order to avoid the problem of water-stop failure caused by excessive local size of the water-stop slit due to local shrinkage in the injection molding process, the upper end cover can be reinforced, such as Figure 6 As shown, reinforcing ribs 35 are added to the connecting column 324 .

[0120] Alternatively, if Figure 3 and Figure 7 As shown, in addition to controlling the assembly gap between the upper end cap and the bottle body 30 to be within 1 mm, a slit 38 with a gap within 1 mm can also be designed on the upper end cap to increase the water flow area, which is not easy to be blocked in actual use.

[0121] Optionally, in order to adapt to the two scenarios of refrigerator compartment and horizontal installation, a detachable handle 37 is designed at the tail of the filter. When the filter is installed on the top or door of the refrigerator compartment, the filter and the socket are rotated and installed. At this time, the tail of the filter body can be grasped without the handle 37. When the filter is installed horizontally, the user has no other contact position. In this scenario, the filter is equipped with a handle 37, and disassembly and assembly are achieved by grasping the handle 37.
