[0028] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0029] It should be understood that the terms used herein, such as "upper", "lower", "outer", "inner", etc., indicating spatial relative positions are used for the purpose of convenience to describe the relationship of one unit or feature relative to another unit or feature as shown in the drawings. The spatial relative position terms may be intended to include different orientations of the device in use or operation other than the orientation shown in the drawings.

[0030] refer to Figures 1 to 5 As shown, a preferred embodiment of the present invention provides a water channel integrated structure, which filters the external water source and supplies water to the water dispenser and ice maker to ensure the safety of users' water use.

[0031] Specific, with reference Figure 1As shown, a water circuit integrated structure includes a filter 10, a water valve 20 and a kettle 30 connected in sequence. In this embodiment, the filter 10 is connected to an external water source, and after filtering the external water source, the filtered water is delivered to the water valve 20 by using the water pressure of the external water source, and is controlled by the water valve 20 to be delivered to the kettle 30 for use by the user.

[0032] Specific, with reference Figure 2 As shown, the water valve 20 has a water inlet 21 connected to the filter 10 and a water outlet 22 connected to the kettle 30. In this embodiment, the filtered water in the filter 10 enters the water valve 20 through the water inlet 21 and is then transported to the kettle 30 through the water outlet 22.

[0033] Further, with reference to Figure 3 As shown, the water valve 20 also has a water flow channel connecting the water inlet 21 and the water outlet 22 and a one-way component 24 disposed in the water flow channel. In this embodiment, the one-way component 24 conducts the water flow in the diversion channel in a one-way manner, that is, the water flow flowing into the diversion channel from the water inlet 21 can only flow out from the water outlet 22, but cannot flow out from the water inlet 21, thereby preventing the water flow in the water valve 20 from flowing back.

[0034] The one-way component 24 is integrated inside the water valve 20, which prevents the one-way component 24 from being damaged when the waterway integrated structure is in use, and effectively protects the one-way component 24. The one-way component 24 and the water valve 20 are connected to the water supply waterway of the refrigerator as a whole, which facilitates the assembly of the water supply waterway.

[0035] By integrating the one-way component 24 on the water valve 20, the water circuit can be controlled and backflow of water can be avoided, thereby simplifying the assembly steps of the water circuit integrated structure.

[0036] Specifically, the water flow channel has an inlet waterway 231 connected to the water inlet 21, an outlet waterway 232 connected to the water outlet 22, and a liquid guiding cavity 233 connecting the inlet waterway 231 and the outlet waterway 232, and the inlet waterway 231 and the outlet waterway 232 are located on the same side of the liquid guiding cavity 233.

[0037] In this embodiment, since the water inlet waterway 231 and the water outlet waterway 232 are located on the same side of the liquid guiding cavity 233, the water flow inside the water valve 20 is roughly in a "U"-shaped flow mode, that is, the water flow in the water inlet waterway 231 flows into the water outlet waterway 232 after passing through the liquid guiding cavity 233, thereby changing the water flow direction of the water inlet and outlet valves 20. Compared with the straight-through structure, on the one hand, it saves the space occupied by the length direction of the water valve 20, and on the other hand, it can weaken the water flow impact force inside the guide channel, thereby reducing the water flow impact force on the one-way component 24.

[0038] Furthermore, the one-way component 24 is located in the water inlet waterway 231 and / or the water outlet waterway 232. In this embodiment, since the water in the water inlet waterway 231 and the water outlet waterway 232 flows smoothly along a straight line, the one-way component 24 is arranged in the water inlet waterway 231 and / or the water outlet waterway 232, which can ensure the normal operation of the one-way component 24 and avoid the deflection of the piston.

[0039] Preferably, the one-way component 24 is disposed in the water inlet waterway 231 so that the one-way component 24 is closer to the external water source, ensuring that the water pressure of the external water source is sufficient to drive the one-way component 24 to conduct in one direction, thereby ensuring that the one-way component 24 can supply water normally.

[0040] Specifically, the water inlet waterway 231 includes a water inlet pipeline 231a connected to the water inlet 21 and a water inlet pipe 231b connecting the water inlet pipeline 231a and the liquid guiding cavity 233. In this embodiment, the water flow direction in the water inlet pipeline 231a forms a certain angle with the water flow direction in the water inlet pipeline 231b, and is preferably perpendicular, thereby weakening the impact force of the water flow in the water inlet waterway 231 and reducing the water flow impact force on the one-way component 24.

[0041] Specific, with reference Figure 4 As shown, the water outlet waterway 232 includes a water outlet pipeline 232a connected to the water outlet 22 and a water outlet pipe 232b connecting the water outlet pipeline 232a and the liquid guiding cavity 233. In this embodiment, the water flow direction in the water outlet pipeline 232a and the water flow direction in the water outlet pipeline 232b form a certain angle, and are preferably perpendicular, thereby weakening the impact force of the water flow in the water outlet waterway 232 and reducing the water flow impact force on the one-way component 24.

[0042] Furthermore, the central axis of the water inlet pipe 231b is parallel to the central axis of the water outlet pipe 232b. Figure 3 The water flow direction in the water inlet pipe 231b is opposite to the water flow direction in the water outlet pipe 232b and is parallel to each other, thereby saving the space occupied by the water valve 20 in the length and width directions to the greatest extent.

[0043] Preferably, the one-way component 24 is arranged in the water inlet pipe 231b, and the water inlet pipe 231b and the water outlet pipe 232b are arranged parallel to each other and along the length direction of the water valve 20, so as to provide space for the installation of the one-way component 24 with a slender structure, thereby making full use of the space in the length direction of the water valve 20, thereby saving the space occupied in the width direction of the water valve 20, and making the structure more compact.

[0044] Specifically, the water inlet pipe 231b has a first pipe 231b1 connected to the liquid guiding cavity 233 and a second pipe 231b2 connecting the first pipe 231b1 and the water inlet pipe 231a, and the aperture size of the first pipe 231b1 is larger than the aperture size of the second pipe 231b2. In this embodiment, the water inlet pipe 231b is an elongated tubular structure. Due to the aperture difference between the first pipe 231b1 and the second pipe 231b2 constituting the water inlet pipe 231b, there is a pressure difference in the water flowing through the water inlet pipe 231b, that is, the water pressure in the second pipe 231b2 is relatively large, and the water pressure in the first pipe 231b1 is relatively small.

[0045] Furthermore, the one-way component 24 is disposed in the first tube 231b1. In this embodiment, the one-way component 24 is located in the first tube 231b1, and one end is located at the connection between the first tube 231b1 and the second tube 231b2, so that the water flow pressures flowing into and out of the one-way component 24 are different, which can accelerate the one-way flow of the one-way component 24 and prevent backflow.

[0046] Specifically, the water valve 20 includes a valve body 25 forming a water flow channel and a filter 26 abutting against the valve body 25 and located in the liquid guiding cavity 233. In this embodiment, the filter 26 is clamped to the valve body so as to be unable to move in the liquid guiding cavity 233. The filter 26 is disposed in the liquid guiding cavity 233 at the water flow turning point, and can filter the water flowing through the liquid guiding cavity 233.

[0047] Furthermore, one end of the one-way component 24 that is away from the second tube 231b2 abuts against the filter element 26. In this embodiment, after the one-way component 24 is matched and inserted into the first tube 231b1, no radial deviation of the first tube 231b1 occurs. The one-way component 24 abuts against the second tube 231b2 and the filter element 26 along the axial direction of the first tube 231b1, so no axial deviation of the first tube 231b1 occurs, ensuring the normal operation of the one-way component 24 and facilitating the maintenance and replacement of the one-way component 24 at a later stage.

[0048] Specific, with reference Figure 5 As shown, the one-way component 24 comprises a housing 241 matching the first tube 231b1, a movable member 242 matching the housing 241, and a resilient member 243 abutting against the housing 241 and the movable member 242. In this embodiment, the housing 241 is an elongated tubular structure, and its outer diameter matches the inner diameter of the first tube 231b1.

[0049] The housing 241 has a liquid outlet 241a facing the liquid guiding cavity 233 and a liquid inlet 241b facing the second tube 231b2. In this embodiment, the liquid outlet 241a of the one-way component 24 is facing the liquid guiding cavity 233, and the liquid inlet 241b of the one-way component 24 is facing the second tube 231b2, so that the water flow with a larger water pressure in the second tube 231b2 can more easily enter the one-way component 24, and the water flow with a smaller water pressure in the first tube 231b1 can not easily enter the one-way component 24, so as to achieve the effect of one-way conduction.

[0050] Specifically, when the external water source is disconnected, the movable member 242 is subjected to the elastic force of the resilient member 243 to block the liquid inlet 241b to prevent backflow. When the external water source is connected, the pressure of the external water source drives the resilient member 243 to deform, so that the movable member 242 moves and breaks away from the blockage of the liquid inlet 241b to achieve unidirectional conduction.

[0051] Specifically, the movable member 242 has a piston 242a that matches the liquid inlet 241b, and the resilient member 243 abuts against the end of the piston 242a that is away from the liquid inlet 241b. In this embodiment, the movable member 242 uses the piston 242a to block the liquid inlet 241b. The resilient member 243 abuts against the piston 242a along the axial direction of the water inlet pipe 231b, and the direction of the elastic deformation force is opposite to the direction of the water flow in the water inlet pipe 231b, so that the piston 242a can block the liquid inlet 241b more stably.

[0052] Specifically, the movable member 242 also has a movable rod 242b connected to the piston 242a and matched with the resilient member 243, and the one-way component 24 also has a limiting sleeve 244 matched with the movable rod 242b and a connecting block 245 connecting the limiting sleeve 244 and the shell 241. In this embodiment, the movable rod 242b can move axially along the water inlet pipe 231b in the limiting sleeve 244, and the limiting sleeve 244 limits the radial movement of the movable rod 242b along the water inlet pipe 231b. The one-way component 24 includes a plurality of connecting blocks 245, which are circumferentially arranged around the axis of the water inlet pipe 231b, and the liquid outlet 241a is formed between the shell 241 and the adjacent connecting blocks 245, so that the one-way component 24 has a plurality of liquid outlets 241a of the same size, so that the water flow is more stable and uniform out of the one-way component 24.

[0053] Furthermore, the resilient member 243 abuts against the end of the connecting block 245 and / or the limiting sleeve 244 away from the liquid outlet 241a. In this embodiment, the resilient member 243 is sleeved on the movable rod 242b, and the two ends abut against the piston 242a and the connecting block 245 and / or the limiting sleeve 244 respectively, so as to prevent the resilient member 243 from falling off during the deformation process.

[0054] Furthermore, the one-way component 24 further includes a guide block 246 disposed on the inner wall of the housing 241, and the inner diameter of the guide block 246 gradually increases from the liquid inlet 241b toward the liquid outlet 241a. Figure 5 The cross-sectional shape of the guide block 246 is conical, and it can guide the piston 242a when the piston 242a moves toward the liquid inlet 241b, so that the piston 242a can smoothly block the liquid inlet 241b to prevent the one-way component 24 from generating backflow.

[0055] Furthermore, the valve body 25 has an installation opening 251 that exposes the flow guide cavity 233 and matches the filter element 26, and the water valve 20 also includes a cover plate 27 connected to the valve body 25 and shielded on the installation opening 251. In this embodiment, the installation opening 251 is provided to facilitate the installation and replacement of the filter element 26 and the one-way component 24. The cover plate 27 is bonded and fixed to the valve body 25 to ensure the sealing and sealing strength of the water flow channel. The cover plate 27 abuts against the filter element 26, thereby limiting the filter element 26 and the one-way component 24 from falling off, and improving the installation strength of the filter element 26 and the one-way component 24.

[0056] Furthermore, the water valve 20 also has a water supply port 28. In this embodiment, the water valve 20 is preferably configured as a one-inlet and two-outlet valve, and the water supply port 28 is preferably used to supply water to an ice maker.

[0057] Furthermore, the valve body 25 also has a water supply path 234 connecting the water supply port 25 and the liquid guiding cavity 233, and the water supply path 234, the water inlet path 231, and the water outlet path 232 are located on the same side of the liquid guiding cavity 233. In this embodiment, similarly, the water supply path 234, the water inlet path 231, and the water outlet path 232 are all arranged on the same side of the liquid guiding cavity 233, so that the direction of the water flow from the water inlet path 231 to the water supply path 234 can be turned. Compared with the straight-through structure, on the one hand, it saves the space occupied by the length direction of the water valve 20, and on the other hand, it can weaken the water flow impact force inside the diversion channel, thereby reducing the water flow impact force on the one-way component 24.

[0058] Specifically, the water supply circuit 234 includes a water supply pipe 234a connected to the water supply port 28 and a water supply pipe 234b connecting the water supply pipe 234a and the liquid guiding cavity 233. The central axis of the water supply pipe 234b is parallel to the central axis of the water inlet pipe 231b. The water circuit inside the water valve 20 is reasonably laid out to make the water circuit inside the water valve 20 more compact, thereby saving the space occupied by the water valve 20.

[0059] Furthermore, a pressure stabilizer 29 is provided in the water supply pipe 234b. The pressure stabilizer 29 is made of elastic material and has a through hole smaller than the water supply pipe 234b, and the through hole can ensure that the water pressure supplied to the ice maker is stable.

[0060] Furthermore, the water valve 20 further includes a first switch 20a and a second switch 20b connected to the valve body 25, the first switch 20a being arranged between the water outlet pipe 232b and the water outlet pipeline 232a, and the second switch 20b being arranged between the water supply pipe 234b and the water supply pipeline 234a. The first switch 20a and the second switch 20b are configured as electromagnetic switches, which can switch on and off the water outlet waterway 232 and the water supply waterway 234.

[0061] refer to Figures 6 to 12 As shown, another preferred embodiment of the present invention provides a water channel integrated structure, which, on the basis of the above embodiment, adds a connection seat 40, so as to facilitate the replacement of the filter 10 while ensuring that the water flow integrated structure can still supply water to the refrigerator when the filter is replaced. In this embodiment, the same reference numerals represent the same components with similar functions and are not described in detail.

[0062] Specific, with reference Figure 1 As shown, a water channel integrated structure includes a filter 10 and a connection seat 40 that can be detachably connected to the filter 10. In this embodiment, the filter 10 is connected to the water valve 20 by using the connection seat 40.

[0063] Specific, with reference Figure 6 As shown, the connection base 40 has an input connector 41 and an output connector 42, and the input connector 41 is connected to the external water circuit. In this embodiment, the input connector 41 is connected to the external water source, and the output connector 42 is connected to the water valve 20, so that the filter 10 filters the external water source and then delivers it to the water valve 20, and then the water valve 20 delivers it to the kettle 30 or the ice maker.

[0064] Further, with reference to Figure 7 As shown, the connecting seat 40 is formed with a flow guide channel 43, and includes a connector 44 that is connected to the filter 10 and a connecting structure 45 that connects two connectors and cooperates with the connector 44. In this embodiment, the connector 44 is used to connect with the inlet and outlet of the filter 10. The connecting structure 45 is used to fix the filter 10, and relative movement can be generated between the connector 44 and the connecting structure 45. The two connectors refer to the input connector 41 and the output connector 42.

[0065] Specifically, the connector 44 has a first state in which the two connectors are connected to the filter 10 and a second state in which the two connectors are disconnected from the filter 10. In this embodiment, in the first state, the connector 44 connects the input connector 41 to the inlet of the filter 10 and connects the output connector 42 to the outlet of the filter 10. In the second state, the input connector 41 is disconnected from the inlet of the filter 10, and the output connector 42 is disconnected from the outlet of the filter 10.

[0066] Furthermore, when the guide channel 43 moves to the second state with the connector 44, the guide channel 43 conducts the two connectors. In this embodiment, the guide channel 43 generates relative movement with the connector 44 and the connection structure 45. In the second state, the guide channel 43 connects the input connector 41 and the output connector 42, so that the waterway integrated structure normally supplies water to the kettle 30 or the ice maker. In the first state, the guide channel 43 is disconnected from the input connector 41 and the output connector 42, so as not to affect the connection between the input connector 41 and the output connector 42 and the filter 10.

[0067] A guide channel 43 is formed between the joint member 44 and the connecting structure 45 to ensure that the water channel integrated structure can still supply water to the refrigerator when the filter 10 is replaced, thereby meeting the user's water demand.

[0068] Specifically, the connector 44 has a matching portion 441 that is rotatably matched with the connection structure 45 and a connector portion 442 that is connected to the matching portion 441. In this embodiment, the connector 44 is rotatably arranged on the connection structure 45 through the matching portion 441, and the conversion between the first state and the second state is achieved through the rotation of the connector 44, which is convenient to operate. Moreover, the way in which the connector 44 converts the state by rotation saves the space occupied by the connection seat 40 compared to the way of parallel movement.

[0069] Of course, in some embodiments, the connector 44 can also change its state by moving in parallel.

[0070] Further, in the first state, the connector 442 connects the filter 10 with the two connectors. In this embodiment, the connector 44 includes two connectors 442 for docking with the two connectors. In the first state, the two connectors 442 connect the input connector 41 to the inlet of the filter 10 and the output connector 42 to the outlet of the filter 10.

[0071] Specifically, the input connector 41 and the output connector 42 are located on the same side of the connector 44. In this embodiment, the input connector 41 and the output connector 42 are located on the same side of the connector 44, which can save the empty space occupied by the connector seat 40 in the axial direction of the input connector 41 and the output connector 42. The central axis of the input connector 41 and the central axis of the output connector 42 are parallel to each other.

[0072] Furthermore, the rotation axis of the mating portion 441 is parallel to the central axes of the two connectors. In this embodiment, when the mating portion 441 rotates around its own rotation axis to change the state, the mating portion 441 is preferably configured as a circular structure, so the rotation axis of the mating portion 441 is preferably configured as the central axis of the mating portion. Since the rotation axis of the mating portion 441 is parallel to the central axes of the input connector 41 and the output connector 42, the space of the connection structure 45 occupied by the connector 44 remains unchanged when the connector 44 rotates.

[0073] Of course, in some embodiments, the rotation axis of the joint member 44 may also be perpendicular to the central axes of the input connector 41 and the output connector 42 .

[0074] Specifically, the filter 10 includes a housing 11 forming a receiving chamber. In this embodiment, a filter element is installed in the receiving chamber.

[0075] Furthermore, the housing 11 is docked with the joint portion 442 along the central axis of the mating portion 441, and is rotationally engaged with the connecting structure 45 around the central axis of the mating portion 441. In this embodiment, the housing 11 is docked with the connecting structure 45 along the axial direction of the mating portion 441, and the housing 11 and the connecting structure 45 are threadedly engaged, and the housing 11 is limitedly disposed on the connecting structure 45 after the two are rotationally connected.

[0076] Furthermore, the central axis of the joint portion 442 is parallel to the central axis of the two connectors. In this embodiment, the rotation axis of the housing 11 is parallel to the rotation axis of the matching portion 441, so that when the filter 10 is disassembled, the input connector 41 and the output connector 42 can be disconnected from the filter 10, and the input connector 41 and the output connector 42 can be connected to the guide channel 43, thereby avoiding leakage of the waterway integrated structure; it is also possible to disconnect the input connector 41 and the output connector 42 from the guide channel 43 when the filter 10 is installed, and the input connector 41 and the output connector 42 can be connected to the filter 10, thereby ensuring the normal conduction between the filter 10 and the external water source and the water valve 20, avoiding secondary operations by the user.

[0077] Of course, in some embodiments, the housing 11 and the connection structure 15 may be fixed by plugging.

[0081] In this embodiment, the rotation slot 453 is preferably provided on the connection structure 45, and the rotation block 443 is provided on the joint member 44. The setting of the rotation positioning structure limits the rotation stroke of the matching portion 441, avoids excessive rotation between the joint member 44 and the connection structure 45, and thus avoids user misoperation.

[0082] Specifically, the connection structure 45 includes a connecting member 454 forming a connecting groove 451 , a limiting member 455 connected to the connecting member 454 , and a limiting groove 456 formed between the connecting member 454 and the limiting member 455 , and at least a portion of the matching portion 441 protrudes into the limiting groove 456 .

[0085] Specifically, the two connectors are connected to the connector 454. Figure 6The input connector 41 and the output connector 42 are integrally formed with the connector 454 and are located on the same side of the connector 454 , thereby reducing the manufacturing cost of the connector socket 20 .

[0086] Specifically, the stopper 455 is located in the connection groove 451, and the connector 44 further has a guide groove 49 disposed at one end of the matching portion 441 away from the connector portion 442, and the guide channel 43 is formed in the guide groove 49. In this embodiment, the stopper 455 is fixedly connected to the connector 454 and is located in the connection groove 451. The guide channel 43 is formed in the guide groove 49, and the guide groove 49 is disposed on the connector 44, so that the manufacturing cost of the connector 20 is relatively low.

[0087] Further, with reference to Figure 6 and Figure 8 As shown, the connecting seat 40 also includes a movable block 46 that cooperates with the connecting member 454 and an elastic member 47 that abuts against the movable block 46 and the connecting member 454. A positioning groove 444 that matches the movable block 46 is provided on the connector 44, and the elastic member 47 abuts against the movable block 46 along the central axis of the two connecting heads.

[0088] In this embodiment, two positioning grooves 444 are preferably provided on the connector 44. When the connector is in the first state and / or the second state, the movable block 46 is supported in the positioning groove 444 by the elastic member 47, thereby prompting the user to rotate to the correct position.

[0089] refer to Figures 9 to 12 As shown, the present invention provides another embodiment of the connection socket 40. In this embodiment, the same reference numerals represent the same elements with similar functions and are not further described.

[0090] Specific, with reference Fig. 9 As shown, the two connectors are connected to the stopper 455. In this embodiment, the input connector 41 and the output connector 42 are integrally formed with the stopper 455 and are located on the same side of the stopper 455, thereby reducing the manufacturing cost of the connection base 20.

[0091] Further, with reference to Fig.10 and Fig.11 As shown, the connecting seat 40 also includes a sealing member 48 that cooperates with the connector 44 and abuts against the limiting member 455, and a guide groove 49 arranged at the end of the sealing member 48 away from the connector portion 442, and the guide channel 43 is formed in the guide groove 49.

[0092] In this embodiment, the sealing member 48 is fixedly connected to the connector 44, so as to move with the connector 44. The provision of the sealing member 48 improves the sealing performance of the connector 44 and the input connector 41 and the output connector 42. The guide channel 43 is formed in the guide groove 49, and the guide groove 49 is provided on the sealing member 48 to improve the sealing performance of the connection seat 20.

[0093] Further, with reference to Figure 8 As shown, the connection seat 40 includes a connector 44 connected to the filter 10 and a seal 48 disposed between the connector 44 and the two connectors. In this embodiment, the provision of the seal 48 improves the sealing performance of the connector 44 and the input connector 41 and the output connector 42.

[0094] Further, with reference to Fig.10 As shown, the two connectors and the connector member 44 are switched between a connected state and a disconnected state based on the movement of the seal 48. In the disconnected state, the seal 48 shields the two connectors. In this embodiment, in the connected state, the input connector 41 and the output connector 42 are both connected to the connector member 44. In the disconnected state, the seal 48 shields the input connector 41 and the output connector 42, so that the input connector 41 and the output connector 42 are disconnected from the connector member 44.

[0095] Through the movement of the sealing member 48 between the connector 44 and the two connectors, the connector 44 and the two connectors can be switched between a connected state and a disconnected state. In the disconnected state, the sealing member 48 can seal the two connectors to prevent leakage in the water supply channel, so that the user does not need to manually close or open the water supply source, which simplifies the filter replacement process and improves the user experience.

[0096] Further, with reference to Fig.11 As shown, the connecting seat 40 also includes a connecting structure 45 that connects the two connecting heads and cooperates with the connecting member 44. The sealing member 48 has two connecting holes 481 that match the connecting member 44. When the sealing member 48 moves to the connecting state with the connecting member 44, the two connecting holes 481 are respectively connected to the two connecting heads.

[0097] In this embodiment, the connector 44 is movably arranged on the connecting structure 45, and the sealing member 48 can move together with the connector 44, which can not only facilitate the removal of the filter 10, but also drive the sealing member 48 to seal the input connector 41 and the output connector 42, so that when the filter 10 is installed, the filter 10 can be automatically connected with the input connector 41 and the output connector 42.

[0098] Furthermore, the connector 44 has a mating portion 441 rotatably mated with the connection structure 45 and a connector portion 442 connected to the mating portion 441 . A guide channel 43 is formed on the seal 48 . When in the disconnected state, the guide channel 43 connects the two connectors.

[0099] In this embodiment, after the filter 10 is removed, the guide channel 43 on the seal 48 can connect the input connector 41 and the output connector 42, and the water channel integrated structure can continue to supply water to the refrigerator, achieving uninterrupted water supply and meeting the user's water needs.

[0100] Furthermore, the matching portion 441 has a mounting groove 441a matching the sealing member 48, and a positioning tube 441b protruding from the mounting groove 441a and communicating with the joint portion 442. In this embodiment, the matching portion 441 is preferably provided with two positioning tubes 441b to dock with the two docking portions 442.

[0101] Specifically, the seal 48 is fixed in the installation groove 441a, and at least a portion of the positioning tube 441b is exposed in the connection hole 481. In this embodiment, the seal 48 is installed in the installation groove 441a to limit the radial offset between the seal 48 and the matching portion 441. After the positioning tube 441b is inserted into the connection hole 481, the joint member 44 drives the seal 48 to rotate more stably. The seal 48 is fixedly connected to the joint member 44, so that the seal 48 rotates firmly with the joint member 44.

[0102] Further, with reference to Fig.12 As shown, the connection structure 45 has a stopper 455 abutting against the sealing member 48. In this embodiment, the end of the stopper 455 opposite to the sealing member 48 is a planar structure.

[0103] Specific, with reference Fig. 9 As shown, the seal 48 has a first sealing boss 482 that abuts against the limiting member 488 and matches the connecting hole 481 , and a second sealing boss 483 that abuts against the limiting member 488 and surrounds the outer side of the first sealing boss 482 , and the guide channel 43 is located between the first sealing boss 482 and the second sealing boss 483 .

[0104] In this embodiment, the first sealing boss 482 and the second sealing boss 483 protrude toward the limiter 455 to abut against the plane structure of the limiter 455 to improve the sealing performance between each other. The first sealing boss 482 surrounds the outer edge of the connection hole 481, and the second sealing boss 483 surrounds the outer edge of the seal 48. The first sealing boss 482 can limit the flow of water from between the matching portion 441 and the seal 48 into the connection hole 481, and the second sealing boss 483 can limit the leakage between the matching portion 441 and the seal 48 to the outside of the connection structure 45. Therefore, in the disconnected state, the space between the first sealing boss 482 and the second sealing boss 483 can conduct the input connector 41 and the output connector 42.

[0105] Furthermore, the sealing member 48 also has a third sealing boss 484 abutting against the limiting member 455 and located on the inner side of the second sealing boss 483 . The third sealing boss 484 is spaced apart from the first sealing boss 482 , and the guide channel 43 is formed on the third sealing boss 484 .

[0106] In this embodiment, when in the disconnected state, the third sealing boss 484 can limit the water in the guide channel 43 from leaking out, the first sealing boss 482 can limit the water flow entering the connecting hole 481, and the second sealing boss 483 can limit the leakage between the matching part 441 and the sealing part 48 to the outside of the connecting structure 45; when in the connected state, the first sealing boss 482 can limit the water flow entering the connecting hole 481, and the second sealing boss 483 can limit the leakage between the matching part 441 and the sealing part 48 to the outside of the connecting structure 45, thereby achieving a multiple sealing effect and improving the sealing performance.

[0107] Specifically, Fig. 9 The guide channel 43 is formed on the third sealing boss 484 and has two joint cavities corresponding to the two connectors and a conducting cavity connecting the two joint cavities. The third sealing boss 484 is provided with a guide groove 49, and the guide channel 43 is formed in the guide groove 49. The guide groove 49 and the connecting hole 481 are separated by the first sealing boss 482 and the third sealing boss 484.

[0108] Further, with reference to Fig.12 As shown, the mating portion 441 also has a positioning boss 441c protruding from the mounting groove 441a and matching the guide channel 43. The sealing member 48 is provided with a positioning groove 485 matching the positioning boss 441c at one end facing the mating portion 441. The positioning groove 485 and the guide channel 43 are symmetrically arranged on both sides of the sealing member 48.

[0109] In this embodiment, the positioning boss 441c is configured to have the same shape as the guide groove 49. After the positioning boss 441c extends into the positioning groove 485, it can support the positioning groove 485 forming the guide channel 43, thereby improving the pressure bearing strength of the guide channel 43.

[0111] In this embodiment, the ejection block 452 and the ejection portion 112 are mutually matched inclined surface structures. When the shell 11 and the connecting structure 45 are rotationally connected, the ejection block 452 and the ejection portion 112 that cooperate with each other can play a role of rotation guide; when the shell 11 and the connecting structure 45 are rotationally disassembled, the ejection block 452 and the ejection portion 112 that cooperate with each other can facilitate the shell 11 to escape from the connecting groove 451, thereby facilitating the connection and disassembly between the shell 11 and the connecting structure 45.

[0112] Further, with reference to Fig.11 As shown, the connecting seat 40 also includes a rotation positioning structure that enables the connecting structure 45 to be limitedly matched with the joint member 44, and the rotation positioning structure includes a rotation block 443 arranged on one of the connecting structure 45 and the joint member 44 and a rotation groove 453 arranged on the other of the connecting structure 45 and the joint member 44, and the central axis of the rotation groove 453 is colinear with the rotation axis of the matching portion 441.
