[0067] The filter provided by the present invention includes a bottle body 1, a filter element 2 and a water stop element 3, the filter element 2 and the water stop element 3 are both arranged in the bottle body 1, the water stop element 3 includes a water stop portion 30, the water stop portion 30 is provided with a liquid outlet channel 301, the outer wall of the water stop portion 30 and the bottle body 1 enclose a first water stop slit 4, and the water stop portion 30 is provided with a second water stop slit 302 that penetrates the outer wall of the water stop portion 30, so that the first water stop slit 4 and the second water stop slit 302 are connected, and external liquid can enter the bottle body 1 through the first water stop slit 4 and the second water stop slit 302, and flow out from the liquid outlet channel 301 after being filtered by the filter element 2.

[0090] The water purification component provided by the present invention comprises the filter proposed in any of the above embodiments and therefore has all the beneficial effects of the filter.

[0091] like Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 , Fig.14 and Fig.15 As shown, in some embodiments, optionally, the water purification component also includes: a switching member 7, which is arranged in the seat body 6 and can rotate between a first position and a second position, and a first channel 70 is provided on the switching member 7; when the filter is in a disassembled state, the switching member 7 is located in the first position, the switching member 7 and the seat body 6 enclose a second channel 72, and the water inlet 60 and the water outlet 62 are connected through the second channel 72; when the filter is in an assembled state, the switching member 7 is located in the second position, the water inlet 60 is connected with the first water stop slit 4 and the second water stop slit 302 through a part of the first channel 70, and the liquid outlet channel 301 is connected with the water outlet 62 through another part of the first channel 70.

[0092] In this embodiment, the water purification assembly includes a seat body 6, a switching member 7 and a filter. The seat body 6 is provided with a water inlet 60 and a water outlet 62. The switching member 7 is provided with a first channel 70. The switching member 7 is arranged in the seat body 6 and can rotate between a first position and a second position. The filter can be detachably connected to the seat body 6. Fig.13 and Fig.14As shown, when the filter is connected to the seat body 6, the switching member 7 is located in the second position, one end of the first channel 70 is connected to the water inlet 60, the water outlet 62 is connected to the other end of the first channel 70, and the filter is connected to the first channel 70 through the first water-stopping slit 4, the second water-stopping slit 302 and the liquid outlet channel 301, and then the liquid flowing into the seat body 6 from the water inlet 60 flows into the first water-stopping slit 4 and the second water-stopping slit 302 through one end of the first channel 70, and after being filtered by the filter element 2, flows from the liquid outlet channel 301 to the other end of the first channel 70, and then flows from the other end of the first channel 70 to the water outlet 62, and finally flows out of the seat body 6 (the direction of the water flow is shown in FIG. 2 ). Fig.13 As shown by the arrow in the figure, the liquid is filtered and the water quality is improved; Fig.15 As shown, when the filter is separated from the seat body 6, the switching member 7 is located in the first position, and the first channel 70 on the switching member 7 cannot communicate with the water inlet 60 and the water outlet 62, so that the liquid flowing into the water inlet 60 cannot flow into the first channel 70, thereby avoiding leakage when the filter is unplugged. In addition, when the switching member 7 is located in the first position, the outer surface of the switching member 7 and the inner wall surface of the seat body 6 enclose a second channel 72, and the water inlet 60 is connected with the water outlet 62 through the second channel 72 (the water flow direction is as shown in FIG. Fig.15 ), so that when the filter is removed, the liquid can still be transported, ensuring the reliability of liquid transportation. The water purification component proposed in the present application realizes the connection between the water inlet 60 and the water outlet 62 through the outer surface of the switching member 7, and does not need to set a through channel on the switching member 7 to realize the connection between the water inlet 60 and the water outlet 62, which simplifies the manufacturing difficulty of the switching member 7, makes the mold forming of the switching member 7 convenient, reduces the manufacturing cost, and the switching of the connecting channel can be realized by rotating the switching member 7 around its own rotation axis, without the need to set up an additional movement space for the switching member 7, so that the space utilization rate inside the seat body 6 is improved.

[0095] In this embodiment, the switching member 7 and the filter are linked by the limiting cooperation of the first limiting portion 780 and the second limiting portion 306, so that the movement of the switching member 7 does not require the drive of other driving structures, thereby reducing the number of parts and components and reducing the overall volume of the water purification component. Specifically, during the process of assembling the filter, the filter drives the switching member 7 to rotate to the second position, and during the process of disassembling the filter, the filter moves relative to the seat body 6, thereby driving the switching member 7 to switch to the first position.

[0096] Optionally, one of the first limiting portion 780 and the second limiting portion 306 is a limiting block, and the other is a limiting groove.

[0097] In some embodiments, optionally, along the circumference of the water stop portion 30 , a portion of the water stop portion 30 is provided with a second water stop slit 302 and encloses the first water stop slit 4 with the inner wall surface of the bottle body 1 , and another portion of the outer wall of the water stop portion 30 is provided with a second limiting portion 306 .

At the same time, another part of the water stop portion 30 is provided with a second limiting portion 306, which can avoid the setting of the second limiting portion 306 affecting the water stopping effect of the second water stop slit 302 and the first water stop slit 4.

[0099] Optionally, the second water-stopping slits 302 and the second limiting portions 306 are alternately arranged along the circumference of the water-stopping portion 30 .

[0101] In this embodiment, the surface of the switching member 7 is provided with a first sink 74 and at least two second sinks 76, the at least two second sinks 76 are arranged at intervals along the circumferential direction of the rotation of the switching member 7, and the first sink 74 is arranged at one end of the at least two second sinks 76 along the axial direction, thereby achieving the communication of the at least two second sinks 76. When the switching member 7 is located at the first position, the first sink 74, the at least two second sinks 76 and the inner surface of the seat body 6 enclose the second channel 72, and the at least two second sinks 76 are arranged opposite to the water inlet 60 and the water outlet 62, respectively, so that the at least two second sinks 76 can be connected with the water inlet 60 and the water outlet 62, respectively, so that the liquid flowing into the water inlet 60 can flow into the second channel 72 through the second sink 76 corresponding to the water inlet 60, and then flow to the second sink 76 corresponding to the water outlet 62 through the communication with the first sink 74, and then flow out of the seat body 6 through the water outlet 62, so as to achieve the liquid transportation when the filter is removed. The water purification component proposed in the present application is provided with a first sink groove 74 and a second sink groove 76 on the surface of the switching member 7, so as to realize the connection between the water inlet 60 and the water outlet 62, so that when the filter is disassembled, the liquid does not pass through any space inside the switching member 7. For the switching member 7, the processing difficulty of the switching member 7 is reduced, so that the manufacturing cost of the switching member 7 is reduced, and then the overall cost of the water purification component is reduced.

[0102] Optionally, the axis direction of rotation of the switching member 7 is the same as the extension direction of the liquid outlet channel 301 .

[0103] In some embodiments, optionally, the first sink groove 74 is arranged in a ring shape along the circumference of the switching member 7 .

[0104] In this embodiment, the first sink 74 is annular along the circumference of the switching member 7, so that water can flow through the first sink 74 along the circumference of the switching member 7, increasing the liquid flow rate and liquid flow when the switching member 7 is in the first position.

[0105] In some embodiments, optionally, at least two second sinks 76 are provided on two opposite sides of the switching member 7 .

[0106] In this embodiment, at least two second sink grooves 76 are disposed on two opposite sides of the switching member 7 , so that the second sink grooves 76 are symmetrically disposed, which facilitates the processing of the switching member 7 .

[0107] like Fig.17 , Fig.18 , Fig.19 and Fig. 20As shown, in some embodiments, optionally, the switching member 7 includes: a switching column 77, the first channel 70 includes an inlet channel 702 and an outlet channel 704, the inlet channel 702 and the outlet channel 704 are arranged on the switching column 77, the inlet channel 702 is provided with a first inlet and a first outlet that are connected, the outlet channel 704 is provided with a second inlet and a second outlet that are connected, the first inlet and the first outlet are both provided on the side wall of the switching column 77, the second inlet is provided at one end of the switching column 77, and the second outlet is provided on the side wall of the switching column 77; a connecting shell 78 is arranged around one end of the switching column 77 where the second inlet is provided, and the second inlet is connected to the connecting shell 78; in the assembled state, the connecting shell 78 is inserted into the mounting cavity 360, the connecting portion 36 extends into the connecting shell 78, the first outlet is connected to the water stop slit through the mounting cavity 360, the second inlet is connected to the liquid outlet channel 301, the first inlet is connected to the water inlet 60, and the second outlet is connected to the water outlet 62.

[0108] In this embodiment, the switching member 7 includes a switching column 77 and a connecting shell 78. The water inlet channel 702 includes a first inlet and a first outlet, both of which are arranged on the side wall of the switching column 77; the water outlet channel 704 includes a second inlet and a second outlet, the second inlet is arranged at one end of the switching column 77, and the second outlet is arranged on the side wall of the switching column 77. The connecting shell 78 is arranged around the end of the switching column 77 where the second inlet is arranged. In this way, when the filter is installed on the seat body 6, the connecting shell 78 is inserted into the installation cavity 360, and the connecting portion 36 extends into the connecting shell 78, so that The first outlet is connected with the first water-stop slit 4 and the second water-stop slit 302 through the installation cavity 360, and the liquid outlet channel 301 is connected with the water outlet channel 704 through the second inlet. At the same time, the first inlet is opposite to and connected with the water inlet 60, and the second outlet is opposite to and connected with the water outlet 62. The liquid enters the water inlet channel 702 from the water inlet 60 and the first inlet, flows into the first water-stop slit 4 and the second water-stop slit 302 from the first outlet through the installation cavity 360, and after being filtered by the filter, flows from the liquid outlet channel 301 to the second inlet, and then flows from the second outlet to the water outlet 62. This arrangement makes the connection between the switching member 7 and the filter more compact, and reduces the space occupied by the water purification component in the axial direction of the switching member 7.

[0109] It is understandable that the first sink 74 and the second sink 76 are also arranged on the switching column 77. In the assembled state, the end of the first channel 70 connected to the water inlet 60 is also the first inlet, and the end of the first channel 70 connected to the water outlet 62 is also the second outlet.

[0110] Optionally, the second sink 76 corresponding to the water inlet 60 , the first inlet, the second sink 76 corresponding to the water outlet 62 , and the second outlet are sequentially spaced apart along the circumference of the switching column 77 .

[0111] Optionally, a second sealing ring is arranged at the first inlet, and another second sealing ring is arranged at the second outlet.

[0112] Optionally, the connection portion 36 and the connection shell 78 are sealed and connected along the circumference of the connection portion 36 .

[0113] In some embodiments, optionally, a handle is provided on the filter, and the handle is detachably connected to the filter.

[0114] In this embodiment, a detachable handle is provided on the filter, so that the filter can be adapted to different installation scenarios. For example, when the filter is installed on the top or door of the refrigerator compartment, at this time, the filter can be grasped by the tail of the bottle body without using a handle. When the filter is installed horizontally, the user has no other contact position. In this scenario, the handle is installed on the filter, and disassembly and assembly are achieved by grasping the handle. The filter proposed in this application can achieve lean manufacturing and realize differentiated usage scenarios with minimal material changes.

[0115] Optionally, the handle is connected to an end of the filter away from the switching member 7, and the specific installation can be achieved by snap-fitting, sleeve-fitting and the like.

[0116] Optionally, the water purification component further includes a fixing seat, and the seat body 6 is installed on the fixing seat.

[0117] 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.

[0118] 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.

[0119] 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; the water outlet 62 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.

[0120] 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 62 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.

[0121] Optionally, the first refrigerating chamber 80 includes a refrigerator compartment, and the second refrigerating chamber 82 includes a freezer compartment.

[0122] Optionally, the refrigeration device 8 further includes a valve body, which is disposed at the water outlet 62 and is used to switch the connection direction of the water outlet 62 so that the water outlet 62 is connected to the water outlet portion 800 and / or the water outlet 62 is connected to the ice making portion 820 .

[0123] Specifically, the water inlet 60 of the seat body 6 is connected to a water supply part, such as an external faucet or a water tank assembly. When the filter is in an assembled state, liquid flows from the water inlet 60 to the filter, and after being filtered by the filter, flows out from the water outlet 62, and then flows to the water outlet 800 and / or the ice making part 820 under the switching of the valve body.

[0124] In a specific application, the water purification assembly includes a fixing seat, a connection seat (including a water inlet 60 and a water outlet 62), and a water purification module (such as a filter). The water purification module is connected to the connection seat by a rotational installation.

[0125] The socket is composed of a socket body (e.g., a socket body 6), a rotating center rod (e.g., a switching member 7), a welding fixing ring, a water inlet joint (provided with a water inlet 60), a water outlet joint (provided with a water outlet 62), 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., a water stop 3), a filter material (e.g., a filter element 2), a lower end cover, a filter bottle (e.g., a bottle body 1), and a tail. Optionally, the water purification module also includes a handle, and the filter bottle and the tail are completed by rotation welding.

[0126] 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 at an angle (optionally, this angle is 90°) with the water inlet and outlet of the socket body (such as the first inlet and the second outlet), 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 (such as the first sink groove 74 and the second sink groove 76) between the rotating center rod and the socket body, forming a water flow path.

[0127] 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 780) extends into the corresponding notch structure of the upper end cover (e.g., the second limit portion 306). 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.

[0128] 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 is formed.

[0129] 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 bottle, and through the limiting cooperation of the two, the filter drives the rotating center rod to rotate during disassembly and assembly.

[0130] Optionally, the upper end cover is assembled with the filter bottle, and the assembly gap between the upper end cover and the filter bottle (such as a water-stop slit) is controlled within 1 mm, so that when the water purification module is removed, water forms a water film in the slit due to the surface tension of the water.

[0131] 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, for example, Figure 8 As shown, a reinforcing rib 38 is provided on the water stop portion 30 to reduce the shrinkage of the water stop portion 30 during the injection molding process.

[0132] Optionally, in addition to controlling the assembly gap between the upper end cap and the filter bottle to be within 1 mm, a slit with a gap within 1 mm can be designed on the upper end cap to increase the water flow area and prevent clogging in actual use.

[0133] Optionally, in order to adapt to both refrigerator and horizontal installation scenarios, a detachable handle is designed at the tail of the filter. When the filter is installed on the top or door of the refrigerator's refrigerator compartment, the filter and the socket are rotated and installed. At this time, just grasp the tail of the filter bottle without using a handle. When the filter is installed horizontally, the user has no other contact position. In this scenario, the filter is equipped with a handle, and disassembly and assembly are achieved by grasping the handle. Optionally, the installation of the handle and the tail of the filter can be achieved by snapping, socketing or welding, which can achieve lean manufacturing and realize differentiated usage scenarios with minimal material changes.

[0134] The water purification component proposed in the present application drives the rotating center rod to rotate during the installation process of the water purification module, thereby realizing the switching of the bypass channel (for example, the channel formed by the water inlet 60, the second channel 72 and the water outlet 62) to the purification channel (for example, the channel formed by the water inlet 60, the first channel 70, the filter and the water outlet 62), without the need for additional operations, thus saving time and effort.

[0135] Optionally, the long arm is on the rotating central rod, and the notch structure is arranged on the water purification module, and the positions can also be reversed. At the same time, the number of sleeve positions between the rotating central rod and the water purification module should be no less than one.

[0136] Optionally, the notch structure may also be a groove or the like.

The terms "installed", "connected", "connected", "fixed", etc. should be understood in a broad sense.
