DETAILED DESCRIPTION

[0052] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0053] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0054] Refer to the following Figures 1 to 16 According to some embodiments of the present invention, a filter, a water purification component and a refrigeration device 8 are proposed.

[0055] like Figure 1 and Figure 2 As shown, according to one 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, arranged in the bottle body 1; a water stop member 3, arranged in the bottle body 1, located at one end of the filter element 2 and located at the opening 10, the water stop member 3 is provided with a liquid outlet channel 30, and the outer wall of the water stop member 3 and the inner wall surface of the bottle body 1 enclose a water stop slit 4, and the water stop slit 4 is connected with the liquid outlet channel 30 through the filter element 2.

[0056] The filter provided by the present invention comprises a bottle body 1, a filter element 2 and a water stop element 3, wherein the filter element 2 and the water stop element 3 are both arranged in the bottle body 1, the water stop element 3 is provided with a liquid outlet channel 30, and a water stop slit 4 is enclosed between the outer wall of the water stop element 3 and the bottle body 1, and external liquid can enter the bottle body 1 through the water stop slit 4, and flow out through the liquid outlet channel 30 after being filtered by the filter element 2, thereby achieving liquid purification. Among them, a water film can be formed in the water stop slit 4, so that the water stop slit 4 can be used for passing 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, thereby preventing external air from entering the bottle body 1, and then preventing the liquid in the bottle body 1 from flowing out, so as to solve the problem of excessive dripping when replacing the filter.

[0057] It can be understood that when the filter is assembled with other components, the water-stop slit 4 can allow liquid to pass through under the action of liquid pressure. When the filter is removed, the liquid in the water-stop slit 4 can form a water film under the action of water surface tension, thereby preventing the liquid in the bottle body 1 from flowing out.

[0058] It can be understood that the water-stop slit 4 is in a slit shape.

[0059] It should be noted that the water film is used to prevent air from entering the bottle body 1, that is, the water film is used to stop water. The water film refers to a thin film structure formed by water under specific conditions such as a slit.

[0060] like Figure 2 As shown, in some embodiments, optionally, the width H1 of the water-stop slit 4 is greater than 0 mm and less than or equal to 1 mm.

[0061] In this embodiment, when the width H1 of the water-stopping slit 4 is too large, it will affect the formation of the water film, thereby causing the water-stopping function to fail. Setting the width H1 of the water-stopping slit 4 to be greater than 0 mm and less than or equal to 1 mm can ensure the water-stopping function of the water-stopping slit 4 and thereby avoid leakage of the filter.

[0062] Optionally, the width H1 of the water-stop slit 4 is any value among 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, or a value between any two values.

[0063] In some embodiments, optionally, the water stop slit 4 is provided around at least a portion of the circumference of the water stop member 3 along the circumference of the water stop member 3 .

[0064] In this embodiment, the water-stop slit 4 surrounds at least part of the circumference of the water-stop member 3 along the circumference of the water-stop member 3, so that the water-stop slit 4 stops water along the circumference, thereby reducing the risk of filter leakage. At the same time, the water-stop slit 4 surrounds at least part of the circumference of the water-stop member 3 along the circumference of the water-stop member 3, and can also increase the water flow area when the filter is connected to the water supply structure, thereby increasing the water flow rate and improving the filtration speed.

[0065] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, the water stop member 3 includes: a cover body 32, which is arranged in the bottle body 1 and has a gap 5 between the cover body 1, the cover body 32 is located at one end of the filter element 2 and can be limitedly matched with the bottle body 1; a water stop portion 34, which is arranged on the cover body 32, and is located on the side of the cover body 32 close to the opening 10, and a liquid outlet channel 30 is provided on the water stop portion 34, and the liquid outlet channel 30 passes through the cover body 32 and is arranged opposite to the filter element 2, and a water stop slit 4 is enclosed between the water stop portion 34 and the bottle body 1, and the water stop slit 4 is connected with the filter element 2 through the gap 5.

[0066] In this embodiment, the water stop member 3 includes a cover body 32 and a water stop portion 34 arranged on the cover body 32. The cover body 32 is arranged in the bottle body 1. The water stop portion 34 is arranged on the cover body 32 and protrudes from the side of the cover body 32 close to the opening 10. The water stop portion 34 is provided with a liquid outlet channel 30 and encloses a water stop slit 4 with the inner wall surface of the bottle body 1, wherein a gap 5 is provided between the cover body 32 and the bottle body 1, so that the liquid flowing into the water stop slit 4 flows to the filter element 2 through the gap 5, thereby realizing the filtration of the liquid, and the cover body 32 and the bottle body 1 are limitedly matched to realize the fixing of the position of the water stop member 3, thereby ensuring the reliability of water stopping of the water stop slit 4.

[0068] In this embodiment, along the length direction of the liquid outlet channel 30, a part of the water stop portion 34 and the inner wall surface of the bottle body 1 enclose a water stop slit 4, and the other part and the inner wall surface of the bottle body 1 enclose a connecting cavity 38, wherein the width H2 of the connecting cavity 38 is greater than the width H1 of the water stop slit 4, thereby increasing the water flow area, and thus when the filter is used for filtering, it can ensure the speed at which the liquid flows into the bottle body 1, thereby improving the filtration efficiency and reducing the risk of filter clogging.

[0069] It can be understood that the communication cavity 38 is communicated with the water-stop slit 4 along the length direction of the liquid outlet channel 30 .

[0070] In some embodiments, optionally, the number of the communicating cavity 38 and the number of the water-stopping slits 4 are both plural, and the plurality of communicating cavities 38 and the plurality of water-stopping slits 4 are alternately arranged in sequence along the length direction of the liquid outlet channel 30 .

[0071] In this embodiment, the connecting cavity 38 and the plurality of water-stopping slits 4 are alternately arranged in sequence along the length direction of the liquid outlet channel 30. While increasing the overall water flow area, the water-stopping slits 4 can form a plurality of sections of water-stopping water films at intervals along the length direction of the liquid outlet channel 30, thereby forming multi-level waterproofing, thereby reducing the probability of failure of the water-stopping function of the water-stopping component 3 and improving the reliability of water-stopping.

[0072] In some embodiments, optionally, along the length direction of the liquid outlet channel 30 , one of the plurality of communicating cavities 38 and the plurality of water-stopping slits 4 , which is close to the opening 10 , is a water-stopping slit 4 .

[0073] In this embodiment, at least one water-stopping slit 4 is arranged on a side of the connecting cavity 38 close to the opening 10. When the filter is removed, a water film formed by the water-stopping slit 4 close to the opening 10 can prevent the liquid in the connecting cavity 38 from flowing out of the bottle body 1, thereby further reducing the amount of dripping when the filter is removed.

[0074] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, the water stop member 3 also includes: a connecting portion 36, which is arranged at one end of the water stop portion 34 away from the cover body 32, and the liquid outlet channel 30 passes through the water stop portion 34 and the connecting portion 36, and the connecting portion 36 and the bottle body 1 enclose an installation cavity 360, and the installation cavity 360 is connected to the water stop slit 4, and the cross-sectional area of ​​the connecting portion 36 is smaller than the cross-sectional area of ​​the water stop portion 34.

[0075] In this embodiment, the water stop member 3 further includes a connecting portion 36, which is disposed at one end of the water stop portion 34 away from the cover body 32, and encloses a mounting cavity 360 with the inner side wall of the bottle body 1, and then the filter is connected to other components through the mounting cavity 360, so that the filter is more compact after being connected to other components. At the same time, the cross-sectional area of ​​the connecting portion 36 is smaller than the cross-sectional area of ​​the water stop portion 34, thereby providing sufficient installation space for other components.

[0076] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, optionally, the liquid outlet channel 30 is provided with a liquid inlet 302 and a liquid outlet 304, the liquid inlet 302 is arranged close to the filter element 2, and the liquid outlet 304 is arranged at an end of the liquid outlet channel 30 away from the filter element 2 and exposed to the opening 10; wherein, the cross-sectional area of ​​the liquid outlet 304 is smaller than the cross-sectional area of ​​the liquid inlet 302.

[0077] In this embodiment, the cross-sectional area of ​​the liquid outlet 304 of the liquid outlet channel 30 is smaller than the cross-sectional area of ​​the liquid inlet 302, so that the liquid can flow out of the liquid outlet 304 after being fully filtered by the filter element 2, thereby improving the filtering effect on the liquid.

[0078] Alternatively, if Figure 5 As shown, a handle 12 is provided at the rear of the bottle body 1 to facilitate the disassembly and assembly of the filter.

[0079] like Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown, according to one embodiment of the present invention, a water purification component is also proposed, including: a filter as proposed in any of the above embodiments.

[0080] 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.

[0081] In some embodiments, optionally, the water purification component also includes: a seat body 6, which is provided with a water inlet 60 and a water outlet 62, and the filter is detachably connected to the seat body 6; 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 separated from the seat body 6, the switching member 7 is located in the first position, and the two ends of the first channel 70 are staggered with the water inlet 60 and the water outlet 62, and the 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 to the water outlet 62 through the second channel 72; 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 other end of the first channel 70 is connected to the water outlet 62, and the first channel 70 is connected to the filter.

[0082] 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.

Fig.10 As shown by the arrow in the figure, the liquid is filtered and the water quality is improved; Fig.12 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, so that when the filter is unplugged, the liquid can still be transported (the direction of the water flow is as shown in FIG. Fig.12The 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 realizes the switching of the connecting channel by rotating the switching member 7 around its own rotation axis, without additionally setting the movement space of the switching member 7, so that the space utilization rate inside the seat body 6 is improved.

[0083] Optionally, the filter is connected between the two ends of the first channel 70 , so that the liquid can flow into the first channel 70 from the water inlet 60 , 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 .

[0084] In some embodiments, optionally, a first limiting portion is provided on the switching member 7, and a second limiting portion is provided on the water stop member 3, and the first limiting portion and the second limiting portion can cooperate in limiting positions; in the process of connecting or separating the filter and the seat body 6, the first limiting portion and the second limiting portion cooperate in limiting positions to drive the switching member 7 to switch between the first position and the second position.

[0085] In this embodiment, the switching member 7 and the filter are linked by the limiting cooperation of the first limiting portion and the second limiting portion, 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.

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.

[0088] In some embodiments, optionally, the first sink groove 74 is arranged in a ring shape along the circumference of the switching member 7 .

[0089] 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.

[0090] In some embodiments, optionally, at least two second sinks 76 are provided on two opposite sides of the switching member 7 .

[0091] 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 .

[0092] like Fig.14 and Fig.15As 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 4 through the mounting cavity 360, 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.

[0093] 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 connection The part 36 extends into the connection shell 78, so that the first outlet is connected to the water stop slit 4 through the installation cavity 360, and the liquid outlet channel 30 is connected to the water outlet channel 704 through the second inlet. At the same time, the first inlet is opposite to and connected to the water inlet 60, and the second outlet is opposite to and connected to the water outlet 62. The liquid enters the water inlet channel 702 from the water inlet 60 and the first inlet, flows into the water stop slit 4 from the first outlet through the installation cavity 360, and after being filtered by the filter part, 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, and reduces the space occupied by the water purification component in the axial direction of the switching member 7.

[0094] 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.

[0095] 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 .

[0096] Optionally, a second sealing ring is arranged at the first inlet, and another second sealing ring is arranged at the second outlet.

[0097] Alternatively, if Figure 5 As shown, the connection portion 36 and the connection shell 78 are sealedly connected along the circumference of the connection portion 36 .

[0098] In some embodiments, optionally, a handle 12 is provided on the filter, and the handle 12 is detachably connected to the filter.

[0099] In this embodiment, a detachable handle 12 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, at this time, the filter can be grasped by the tail of the bottle body without the need to use the handle 12. When the filter is installed horizontally, the user has no other contact position. In this scenario, the handle 12 is installed on the filter, and disassembly and assembly are achieved by grasping the handle 12. The filter proposed in this application can achieve lean manufacturing and realize differentiated usage scenarios with minimal material changes.

[0100] Optionally, the handle 12 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 connection, etc.

[0101] Optionally, the water purification component further includes a fixing seat, and the seat body 6 is installed on the fixing seat.

[0102] like Fig.16 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.

[0103] 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.

[0104] like Fig.16 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; a water purification component 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.

[0105] 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 purification component 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.

[0106] Optionally, the water outlet 62 of the seat body 6 is in communication with the water outlet portion 800 and the ice-making portion 820 , and is used to supply water to the water outlet portion 800 and the ice-making portion 820 .

[0107] Optionally, the first refrigerating chamber 80 includes a refrigerator compartment, and the second refrigerating chamber 82 includes a freezer compartment.

[0108] 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 .

[0109] 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.

[0110] 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.

[0111] 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 12, and the filter bottle and the tail are completed by rotation welding.

[0112] 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.

[0113] 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) extends into the corresponding notch structure of the upper end cover (e.g., the second limit portion). 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.

[0114] 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.

[0115] 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.

[0116] 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 slit 4) 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.

[0117] Optionally, in order to avoid the problem of water-stop failure caused by the local size of the water-stop slit 4 being too large due to local shrinkage in the injection molding process, the upper end cover can be reinforced, for example, Figure 3 As shown, a cavity is provided between the outer wall of the water stop member 3 and the liquid outlet channel 30, and a reinforcing rib 39 is provided in the cavity. The provision of the cavity can reduce the amount of material used, and the provision of the reinforcing rib 39 can improve the structural strength of the water stop member 3. Thus, during the molding process of the water stop member 3, the problem of excessive shrinkage due to excessive material use, excessive thickness and low structural strength can be avoided, thereby ensuring the size of the water stop slit 4, so that the filter can fully filter the liquid and ensure the filtering effect of the liquid.

[0118] 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.

[0119] Optionally, in order to adapt to the two scenarios of refrigerator compartment and horizontal installation, 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 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 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 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.

[0120] 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.

[0121] 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.

[0122] Optionally, the notch structure may also be a groove or the like.
