Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0063] Refer to the following Figures 1 to 15 The following describes a filter, a water purification component and a refrigeration device 8 according to some embodiments of the present invention.

[0064] like Figure 1 、 Figure 2 and Figure 3 As shown, according to an embodiment of the present invention, the present invention proposes a filter, comprising: a bottle body 1, the bottle body 1 is provided with an opening 10; a filter element 2, provided in the bottle body 1; an injection-molded end cap 3, provided in the bottle body 1, the injection-molded end cap 3 is located at one end of the filter element 2 and at the opening 10, the injection-molded end cap 3 is provided with a liquid outlet channel 30, the liquid outlet channel 30 passes through the injection-molded end cap 3 and is connected with the bottle body 1, the outer side wall of the injection-molded end cap 3 and the bottle body 1 enclose a liquid inlet channel 4, the liquid inlet channel 4 is connected with the liquid outlet channel 30 through the filter element 2, wherein a cavity 31 is provided between the outer side wall of the injection-molded end cap 3 and the liquid outlet channel 30, the cavity 31 is provided around at least part of the circumference of the liquid outlet channel 30, and a reinforcing rib 32 is provided in the cavity 31.

[0065] The filter provided by the utility model includes a bottle body 1, a filter element 2 and an injection molded end cap 3. The filter element 2 is arranged in the bottle body 1 for filtering liquid. The injection molded end cap 3 is arranged in the bottle body 1 and is located at one end of the filter element 2. The injection molded end cap 3 is provided with a liquid outlet channel 30. The outer side wall of the injection molded end cap 3 and the bottle body 1 enclose a liquid inlet channel 4. The liquid inlet channel 4 is connected with the liquid outlet channel 30 through the filter element 2, and then the liquid flows into the bottle body 1 from the liquid inlet channel 4, and flows out from the liquid outlet channel 30 after being filtered by the filter element 2, thereby achieving filtration of the liquid. Among them, a cavity 31 is provided between the outer wall of the injection molded end cover 3 and the liquid outlet channel 30, and a reinforcing rib 32 is provided in the cavity 31. The setting of the cavity 31 can not only reduce the material consumption, but also improve the structural strength of the injection molded end cover 3 by setting the reinforcing rib 32. In this way, during the molding process of the injection molded end cover 3, the problem of excessive shrinkage caused by excessive material consumption, excessive thickness and low structural strength can be avoided, thereby ensuring the size of the liquid inlet channel 4, so that the filter can fully filter the liquid.

[0066] like Figure 2 and Figure 3 As shown, in some embodiments, optionally, there are multiple reinforcing ribs 32 , and the multiple reinforcing ribs 32 are arranged at intervals along the length direction of the liquid outlet channel 30 .

[0067] In this embodiment, a plurality of reinforcing ribs 32 are spaced apart along the length direction of the liquid outlet channel 30 , which can ensure both the final size of the injection-molded end cap 3 and the strength of the injection-molded end cap 3 .

[0068] In some embodiments, optionally, the width of the liquid inlet channel 4 is greater than 0 mm and less than or equal to 1 mm, so that the liquid inlet channel 4 forms a water-stop gap 40 , and a water film can be formed in the water-stop gap 40 .

[0069] In this embodiment, the width of the liquid inlet channel 4 is set to be greater than 0 mm and less than or equal to 1 mm, so that the liquid inlet channel 4 forms a water-stopping gap 40. That is, the size of the water-stopping gap 40 is small, so that it can be used to pass water when the filter and other components are in an assembled state, and can also form a water film due to the surface tension of water when the filter and other components are in a disassembled state, so that the liquid in the bottle body 1 will not flow out of the liquid inlet channel 4, thereby solving the problem of excessive dripping when replacing the filter. At the same time, in order to avoid the situation where the injection molded end cap 3 shrinks too much during the injection molding process, resulting in the liquid inlet channel 4 being too large, a reinforcing rib 32 is provided on the injection molded end cap 3, thereby reducing the local shrinkage during the molding process of the injection molded end cap 3, ensuring the size of the liquid inlet channel 4, and thus ensuring the water-stopping effect of the injection molded end cap 3.

[0071] It can be understood that when the filter and other components are in an assembled state, the liquid inlet channel 4 can allow liquid to pass through, so that there is liquid in the liquid inlet channel 4. Therefore, when the filter is removed, the liquid in the liquid inlet channel 4 can form a water film under the action of the surface tension of water, thereby preventing the liquid in the bottle body 1 from flowing out.

[0072] It can be understood that the water-stop gap 40 is in a slit shape.

[0073] In some embodiments, optionally, the water-stop gap 40 surrounds at least a portion of the circumference of the injection-molded end cover 3 along the circumference of the injection-molded end cover 3 .

The water stop portion 34 is provided with a liquid outlet channel 30, a cavity 31 and a reinforcing rib 32, wherein there is a gap 5 between the cover body 33 and the bottle body 1, so that the liquid flowing into the liquid inlet channel 4 flows to the filter element 2 through the gap 5, thereby realizing the filtration of the liquid, and the cover body 33 and the bottle body 1 are limited and matched to realize the fixing of the position of the injection molded end cap 3, thereby ensuring the reliability of the water stopping of the liquid inlet channel 4.

[0077] like Figure 1 、 Figure 2 and Figure 3As shown, in some embodiments, optionally, the injection-molded end cap 3 further includes: a connecting portion 35, which is provided at the end of the water stop portion 34 away from the cover body 33, the liquid outlet channel 30 passes through the connecting portion 35, and the connecting portion 35 and the inner side wall of the bottle body 1 enclose an installation cavity 350, and the installation cavity 350 is connected to the liquid inlet channel 4.

[0079] In some embodiments, optionally, the cross-sectional area of ​​the connecting portion 35 is smaller than the cross-sectional area of ​​the water-stopping portion 34 .

[0080] In this embodiment, the cross-sectional area of ​​the connecting portion 35 is smaller than the cross-sectional area of ​​the water-stopping portion 34 , thereby providing sufficient installation space for other components.

[0081] like Figure 3 As shown, in some embodiments, optionally, a groove 340 is provided at one end of the water stop portion 34 close to the cover body 33 , and the groove 340 is recessed into the interior of the water stop portion 34 .

[0090] In this embodiment, the water purification assembly includes a base body 6, a switching member 7 and a filter. The base 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 base body 6 and can rotate between a first position and a second position. The filter can be detachably connected to the base body 6. Figure 9 As shown, when the filter is connected to the seat 6, the switching member 7 is in the second position, one end of the first channel 70 is connected to the water inlet 60, and 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 liquid inlet channel 4 and the liquid outlet channel 30, and then the liquid flowing into the seat 6 from the water inlet 60 flows into the filter through one end of the first channel 70, and then flows from the other end of the first channel 70 to the water outlet 62 after being filtered by the filter, and finally flows out of the seat 6, thereby achieving liquid filtration and improving water quality; as shown in FIG. Figure 11As shown, when the filter is separated from the seat 6, the switching member 7 is in the first position, and the first channel 70 on the switching member 7 cannot connect 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 liquid leakage when the filter is unplugged. In addition, when the switching member 7 is in the first position, the outer surface of the switching member 7 and the inner wall surface of the seat 6 enclose a second channel 72, and the water inlet 60 is connected with the water outlet 62 through the second channel 72, so that when the filter is unplugged, the liquid can still be transported, thereby ensuring the reliability of liquid transportation.

[0091] Optionally, in the water purification assembly proposed in the present application, the assembly and disassembly of the filter can be linked to the switching member 7, so that the movement of the switching member 7 does not require the drive of other driving structures, reducing the number of parts and components and reducing the overall volume of the water purification assembly. When the filter is removed, the water inlet 60 and the water outlet 62 are connected through the outer surface of the switching member 7, and there is no need to set a through channel on the switching member 7 to achieve 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, and reduces the manufacturing cost. Moreover, the switching of the connecting channel can be achieved by rotating the switching member 7 around its own rotation axis, and there is no need to set up an additional movement space for the switching member 7, so that the space utilization inside the seat body 6 is improved.

[0092] In addition, after the filter is pulled out, a water film can be formed in the liquid inlet channel 4, thereby preventing water dripping.

[0093] It is understandable that the filter proposed in the present application is detachably connected to the seat 6, so that the filter can be replaced or repaired to ensure the reliability of the water purification component in water purification.

[0094] Optionally, the filter is rotationally engaged with the seat body 6 .

[0095] Optionally, the filter is connected between both ends of the first channel 70 , so that liquid can flow from the water inlet 60 into the first channel 70 , then flow to the filter through the first channel 70 , and then flow to the water outlet 62 through the other end of the first channel 70 .

[0096] like Figure 12 As shown, in some embodiments, optionally, a first limiting portion 74 is provided on the switching member 7, and a second limiting portion 37 is provided on the injection molded end cover 3, and the first limiting portion 74 and the second limiting portion 37 can be limited and matched; in the process of connecting or separating the filter and the seat body 6, the first limiting portion 74 and the second limiting portion 37 are limited and matched to drive the switching member 7 to switch between the first position and the second position.

[0097] In this embodiment, the switching member 7 and the filter are linked by the limited cooperation of the first limit portion 74 and the second limit portion 37. Specifically, during filter assembly, the filter drives the switching member 7 to rotate to the second position. During filter removal, the filter moves relative to the base 6, thereby driving the switching member 7 to switch to the first position.

[0098] like Figure 12 As shown, in some embodiments, optionally, a first sink groove 75 and at least two second sink grooves 76 are provided on the surface of the switching member 7, and the at least two second sink grooves 76 are arranged at intervals along the circumference of the switching member 7. Along the axial direction of rotation of the switching member 7, the first sink groove 75 is located at one end of the at least two second sink grooves 76 and is connected with the at least two second sink grooves 76; when the switching member 7 is in the first position, the at least two second sink grooves 76 are respectively arranged opposite to the water inlet 60 and the water outlet 62, and the first sink groove 75, the second sink groove 76 and the inner wall surface of the seat body 6 enclose a second channel 72; when the switching member 7 is in the second position, the at least two second sink grooves 76 are respectively staggered with the water inlet 60 and the water outlet 62 along the circumference of the switching member 7.

[0099] In this embodiment, the surface of the switching member 7 is provided with a first sink 75 and at least two second sinks 76. The at least two second sinks 76 are spaced apart along the circumferential direction of the rotation of the switching member 7. The first sink 75 is located at one end of the at least two second sinks 76 along the axial direction, thereby connecting the at least two second sinks 76. When the switching member 7 is in the first position, the first sink 75, the at least two second sinks 76, and the inner surface of the base 6 define a second channel 72. The at least two second sinks 76 are respectively located opposite the water inlet 60 and the water outlet 62, thereby connecting the at least two second sinks 76 to the water inlet 60 and the water outlet 62, respectively. In this way, 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, then flow through the first sink 75 to the second sink 76 corresponding to the water outlet 62, and then flow out of the base 6 through the water outlet 62, thereby achieving liquid transportation when the filter is removed. The water purification component proposed in the present application is provided with a first sink 75 and a second sink 76 on the surface of the switching member 7, thereby realizing 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, the manufacturing cost of the switching member 7 is reduced, and the overall cost of the water purification component is reduced.

[0100] In some embodiments, optionally, the first sink groove 75 is arranged in a ring shape along the circumference of the switching member 7 .

[0101] In this embodiment, the first sink 75 is annular along the circumference of the switching member 7, so that water can flow through the first sink 75 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.

[0102] In some embodiments, optionally, at least two second sinks 76 are provided on opposite sides of the switching member 7 .

[0103] In this embodiment, at least two second sinking grooves 76 are provided on opposite sides of the switching member 7 , so that the second sinking grooves 76 are symmetrically arranged, which facilitates the processing of the switching member 7 .

[0104] like Figure 13 and Figure 14 As 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 provided 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 350, the connecting portion 35 extends into the connecting shell 78, the first outlet is connected to the liquid inlet channel 4 through the mounting cavity 350, the second inlet is connected to the liquid outlet channel 30, the first inlet is connected to the water inlet 60, and the second outlet is connected to the water outlet 62.

[0105] 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 provided. In this way, when the filter is installed on the seat body 6, the connecting shell 78 is inserted into the installation cavity 350, and the connection Portion 35 extends into connecting housing 78, so that the first outlet communicates with the liquid inlet channel 4 through the mounting cavity 350, and the liquid outlet channel 30 communicates with the water outlet channel 704 through the second inlet. At the same time, the first inlet is opposite and connected to the water inlet 60, and the second outlet is opposite and connected to the water outlet 62. Liquid enters the water inlet channel 702 from the water inlet 60 and the first inlet, flows from the first outlet through the mounting cavity 350 into the liquid inlet channel 4, and after being filtered by the filter element 2, flows from the liquid outlet channel 30 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, reducing the space occupied by the water purification component in the axial direction of the switching member 7.

[0106] It can be understood that the first sink 75 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.

[0107] 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 .

[0108] Optionally, a second sealing ring is provided at the first inlet, and another second sealing ring is provided at the second outlet.

[0109] Optionally, the connecting portion 35 and the connecting shell 78 are sealed and connected along the circumference of the connecting portion 35 .

[0110] like Figure 4 As shown, in some embodiments, optionally, a handle 12 is provided on the filter, and the handle 12 is detachably connected to the filter.

[0111] In this embodiment, the filter is provided with a removable handle 12, allowing the filter to adapt to different installation scenarios. For example, when installing the filter on the top or door of a refrigerator's cold storage compartment, the filter can be grasped by the rear end of the bottle, eliminating the need for handle 12. When the filter is installed horizontally, the user has no other contact area. In this scenario, handle 12 is attached to the filter, allowing assembly and disassembly by grasping handle 12. The filter proposed in this application can achieve lean manufacturing, realizing differentiated usage scenarios with minimal material changes.

[0112] Optionally, the handle 12 is connected to the 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.

[0113] Optionally, the water purification component further includes a fixing seat, and the seat body 6 is installed on the fixing seat.

[0114] In some embodiments, optionally, along the circumference of the injection-molded end cover 3 , the reinforcing ribs 32 and the second limiting portions 37 are alternately arranged in sequence.

[0115] In this embodiment, the reinforcing ribs 32 and the second limiting portions 37 are alternately arranged along the circumference of the injection molded end cover 3, which can not only ensure the strength of the injection molded end cover 3 and prevent the injection molded end cover 3 from shrinking during molding, but also achieve limiting cooperation with the switching member 7.

[0116] like Figure 15 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.

[0117] The refrigeration device 8 provided by the present invention includes the water purification component proposed in any of the above embodiments, and therefore has all the beneficial effects of the water purification component.

[0118] 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; when the water purification component includes a seat body 6, the water outlet 62 of the seat body 6 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.

[0119] 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 realize the preparation of ice cubes in the chiller.

[0120] Optionally, the first refrigeration chamber 80 includes a refrigerator compartment, and the second refrigeration chamber 82 includes a freezer compartment.

[0121] Optionally, the refrigeration equipment 8 further includes a valve body, which is provided at the water outlet 62 and is used to switch the communication direction of the water outlet 62 so that the water outlet 62 is connected to the water outlet part 800 and / or the water outlet 62 is connected to the ice making part 820.

[0122] Specifically, the water inlet 60 of the base 6 is connected to a water supply, such as an external faucet or a water tank assembly. When the filter is assembled, liquid flows from the water inlet 60 to the filter, is filtered by the filter, and then flows out of the water outlet 62. Then, under the switching of the valve body, it flows to the water outlet 800 and / or the ice making unit 820.

[0123] In a specific application, the water purification assembly includes a fixing base, a connecting base (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 connecting base by a rotating installation.

[0124] The socket consists of a socket body (e.g., socket body 6), a rotating center rod (e.g., switching element 7), a welded fixing ring, a water inlet connector (with a water inlet 60), a water outlet connector (with a water outlet 62), and several sealing rings. The assembly is completed using ultrasonic welding. The water purification module consists of an upper end cap (e.g., a water stop), filter material (e.g., filter element 2), a lower end cap, a filter bottle (e.g., bottle body 1), and a tail. Optionally, the water purification module also includes a handle 12. The filter bottle and tail are completed by rotational welding.

[0125] The water inlet and outlet connectors of the adapter are connected to the water inlet and outlet pipes, respectively. When not installed with a filter, the water inlet and outlet of the rotating center rod (e.g., the first inlet and the second outlet) are offset from the water inlet and outlet of the adapter body (e.g., the water inlet and the water outlet). The sealing ring seals the water inlet and outlet of the rotating center rod against the inner wall of the adapter body, preventing water from flowing into the rotating center rod. Water flowing into the adapter from the water inlet connector then flows through the structural steps and gaps (e.g., the first and second troughs 75 and 76) between the rotating center rod and the adapter body into the water outlet connector, forming a water flow path.

[0126] 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 74) extends into the corresponding notch structure of the upper end cover (e.g., the second limit portion 37). When the water purification module is rotated and fastened with the socket, because the upper end cover and the water purification module are fixedly connected, 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. 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 to achieve a design in which the rotation angle of the rotating center rod is the same or different from that of the water purification module.

[0127] 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.

[0128] 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 between the two, the filter drives the rotating center rod to rotate during disassembly and assembly.

[0129] 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 the water-stop gap 40) is controlled within 1 mm, so that when the water purification module is removed, water forms a water film in the narrow gap due to the surface tension of the water.

[0130] Optionally, in order to avoid the problem of water-stop failure caused by the local size of the water-stop gap 40 being too large due to local shrinkage in the injection molding process, the upper end cover can be reinforced.

[0131] 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 of less than 1 mm can be designed on the upper end cap to increase the water flow area and prevent clogging during actual use.

[0132] Optionally, in order to adapt to both refrigerator and horizontal installation scenarios, a detachable handle 12 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, the filter can be grasped by the tail of the bottle body without the need for the handle 12. When the filter is installed horizontally, the user has no other contact position. In this scenario, the filter is equipped with a handle 12, and disassembly and assembly are achieved by grasping the handle 12. Optionally, the installation of the handle 12 to 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.

[0133] The water purification component proposed in this 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 operation, saving time and effort.

[0134] Optionally, the long arm is on the rotating central rod, and the notch structure is provided on the water purification module, and the positions can also be reversed. At the same time, the number of socket positions between the rotating central rod and the water purification module should be no less than one.

[0135] Optionally, the notch structure may also be a groove structure, etc.
