Description

Technical Field

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

[0002] At present, a water purification component includes a seat body and a rotating part arranged in the seat body. The rotating part can rotate when driven by the purification part, so that when the purification part is installed on the seat body, the purification flow path is connected, and when the purification part is removed, the liquid inlet and the liquid outlet are disconnected, thereby avoiding leakage. However, in the related art, in the process from the liquid inlet and the liquid outlet being connected to the purification flow path to the liquid inlet and the liquid outlet being disconnected, the rotation angle of the rotating part is relatively large, which not only increases the friction of the rotating part, but also increases the rotation stroke of the rotating part when the liquid inlet and the liquid outlet are disconnected, thereby increasing the risk of leakage. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] To this end, a first aspect of the present invention provides a water purification component.

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

[0006] In view of this, a first aspect of the present invention proposes a water purification component, including a seat body, which is provided with a liquid inlet and a liquid outlet; a rotating member, which is arranged in the seat body and can rotate in the seat body, and the rotating member is provided with a purification channel; a purification member, one of the purification member and the rotating member is provided with a limiting groove, and the other is provided with a limiting plate, the purification member is detachably connected to the seat body, and during the process of connecting or disassembling the purification member and the seat body, the limiting plate and the limiting groove are limitedly matched to enable the purification member to drive the rotating member to rotate between a first position and a second position; when the rotating member is in the first position, the purification channel is staggered with the liquid inlet and the liquid outlet; when the rotating member is in the second position, one end of the purification channel is connected with the liquid inlet, and the other end is connected with the liquid outlet, and the purification member is connected between the two ends of the purification channel, wherein along the circumferential direction of rotation of the rotating member, the width of the limiting groove is greater than the width of the limiting plate.

[0007] The water purification component provided by the present invention comprises a seat body, a rotating member and a purification member. The seat body is provided with a liquid inlet and a liquid outlet, the rotating member is provided with a purification channel, the rotating member is arranged in the seat body and is rotatably connected to the seat body, the purification member can be detachably connected to the seat body, and in the process of disassembling and assembling the purification member relative to the seat body, the limiting cooperation of the limiting groove and the limiting plate enables the purification member to drive the rotating member to rotate between a first position and a second position to realize the switching of the path connected between the liquid inlet and the liquid outlet, so that the movement of the rotating member does not need to be driven by other driving structures, thereby reducing the number of components and the overall volume of the water purification component. Among them, when the rotating part is in the second position, one end of the purification channel is connected with the liquid inlet, the liquid outlet is connected with the other end of the purification channel, and the purification part is connected with the purification channel, so that the liquid flowing into the seat body from the liquid inlet flows into the purification part through one end of the purification channel, and then flows to the liquid outlet from the other end of the purification channel after being filtered by the purification part, and finally flows out of the seat body, thereby realizing the filtration of the liquid and improving the water quality; when the rotating part is in the first position, the purification channel on the rotating part cannot be connected with the liquid inlet and the liquid outlet, so that the liquid flowing into the liquid inlet cannot flow into the purification channel, thereby avoiding leakage when the purification part is unplugged. In addition, along the circumferential direction of rotation of the rotating part, the width of the limit groove is greater than the width of the limit plate, so that during the disassembly and assembly of the purification part and the seat body, the rotation angle of the rotating part is smaller than the rotation angle of the purification part. In this way, when the purification part is installed on the seat body, the rotating part can rotate a smaller angle to connect the liquid inlet and the liquid outlet with the purification channel, which can not only reduce the rotational friction of the rotating part, but also enable the liquid inlet and the liquid outlet to be quickly connected with the purification channel, reducing the risk of leakage; similarly, when the purification part is disassembled, the rotating part can also rotate a smaller angle to disconnect the liquid inlet and the liquid outlet from the purification channel, reducing the risk of leakage.

[0008] It can be understood that since the width of the limit groove is greater than the width of the limit plate, when the purification component is screwed into the seat body, the limit plate and the limit groove cannot be limitedly matched within a certain angle range, and thus the purification component cannot drive the rotating component to rotate. When the purification component is rotated to a certain position, the limit plate fits against the side wall of the limit groove, and then when the purification component continues to rotate, the rotating component rotates accordingly, so that the rotation angle of the rotating component during the installation or disassembly of the purification component is smaller.

[0009] The water purification component provided by the present invention may also have the following additional technical features:

[0010] In some embodiments, optionally, along the axial direction of rotation of the rotating member, the length of the limiting plate is less than or equal to the length of the limiting groove.

[0011] In this embodiment, the length of the limit plate is smaller than the length of the limit slot. On the one hand, it can avoid the interference between the limit plate and the limit slot along the axial direction and affect the installation of the purification component. On the other hand, it can also make the limit plate completely inserted into the limit slot, thereby making the rotating component and the purification component more compact along the axial direction, which is beneficial to reducing the overall length of the water purification component along the axial direction of the rotating component.

[0012] In some embodiments, optionally, a notch is provided at one end of the limiting groove along the axis direction of rotation of the rotating member, and the limiting plate can be inserted into the limiting groove through the notch.

[0013] In this embodiment, a notch is provided at one end of the limiting groove along the axial direction of the rotating part. When the purification part is installed, the limiting plate can be inserted into the limiting groove through the notch, and then the rotation of the rotating part is realized by the rotation of the purification part, so that the connection between the limiting plate and the limiting groove is simple and reliable.

At the same time, one of the limit groove and the limit plate is arranged on the bottle body or the end cap, so that the rotating member is limited and matched with the bottle body or the end cap, and then during the disassembly and assembly of the purification component, the rotating member is driven to rotate, so that the structure is stable and reliable.

DETAILED DESCRIPTION

[0057] 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.

[0058] 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.

[0059] Refer to the following Figures 1 to 21 A water purification assembly and a refrigeration device according to some embodiments of the present invention are described.

[0060] like Figure 1 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 , Fig.14 and Fig.15As shown, according to one embodiment of the present invention, the present invention proposes a water purification component, including a seat body 1, provided with a liquid inlet 10 and a liquid outlet 12; a rotating member 2, which is arranged in the seat body 1 and can rotate in the seat body 1, and the rotating member 2 is provided with a purification channel 20; a purification member 3, one of the purification member 3 and the rotating member 2 is provided with a limiting groove 36, and the other is provided with a limiting plate 28, the purification member 3 is detachably connected to the seat body 1, and in the process of connecting or disassembling the purification member 3 and the seat body 1, the limiting plate 28 and the limiting groove 36 are limited and cooperated , so that the purification member 3 drives the rotating member 2 to rotate between the first position and the second position; when the rotating member 2 is in the first position, the purification channel 20 is staggered with the liquid inlet 10 and the liquid outlet 12; when the rotating member 2 is in the second position, one end of the purification channel 20 is connected with the liquid inlet 10, and the other end is connected with the liquid outlet 12, and the purification member 3 is connected between the two ends of the purification channel 20, wherein, along the circumferential direction of rotation of the rotating member 2, the width W1 of the limit groove 36 is greater than the width W2 of the limit plate 28.

[0061] The water purification component provided by the present invention comprises a seat body 1, a rotating member 2 and a purification member 3. The seat body 1 is provided with a liquid inlet 10 and a liquid outlet 12, the rotating member 2 is provided with a purification channel 20, the rotating member 2 is arranged in the seat body 1 and is rotatably connected to the seat body 1, the purification member 3 can be detachably connected to the seat body 1, and in the process of disassembling and assembling the purification member 3 relative to the seat body 1, through the limiting cooperation of the limiting groove 36 and the limiting plate 28, the purification member 3 can drive the rotating member 2 to rotate between the first position and the second position, so as to realize the switching of the path connected between the liquid inlet 10 and the liquid outlet 12, so that the movement of the rotating member 2 does not need to be driven by other driving structures, thereby reducing the number of components and reducing the overall volume of the water purification component. Among them, when the rotating member 2 is in the second position, one end of the purification channel 20 is connected to the liquid inlet 10, the liquid outlet 12 is connected to the other end of the purification channel 20, and the purification member 3 is connected to the purification channel 20, so that the liquid flowing into the seat body 1 from the liquid inlet 10 flows into the purification member 3 through one end of the purification channel 20, and then flows to the liquid outlet 12 from the other end of the purification channel 20 after being filtered by the purification member 3, and finally flows out of the seat body 1, thereby achieving the filtration of the liquid and improving the water quality (the direction of the water flow is as follows Fig.13When the rotating member 2 is in the first position, the purification channel 20 on the rotating member 2 cannot communicate with the liquid inlet 10 and the liquid outlet 12, so that the liquid flowing into the liquid inlet 10 cannot flow into the purification channel 20, thereby avoiding leakage when the purification member 3 is unplugged. In addition, along the circumferential direction of rotation of the rotating part 2, the width W1 of the limit groove 36 is greater than the width W2 of the limit plate 28, so that during the disassembly and assembly of the purification part 3 and the seat body 1, the rotation angle of the rotating part 2 is smaller than the rotation angle of the purification part 3. In this way, when the purification part 3 is installed on the seat body 1, the rotating part 2 can rotate a smaller angle to connect the liquid inlet 10 and the liquid outlet 12 with the purification channel 20, which can not only reduce the rotational friction of the rotating part 2, but also enable the liquid inlet 10 and the liquid outlet 12 to be quickly connected with the purification channel 20, reducing the risk of leakage; similarly, when the purification part 3 is disassembled, the rotating part 2 can also rotate a smaller angle to disconnect the liquid inlet 10, the liquid outlet 12 from the purification channel 20, reducing the risk of leakage.

[0062] It can be understood that since the width W1 of the limit groove 36 is greater than the width W2 of the limit plate 28, when the purification component 3 is screwed into the seat body 1, the limit plate 28 and the limit groove 36 cannot be limitedly matched within a certain angle range, and thus the purification component 3 cannot drive the rotating component 2 to rotate. When the purification component 3 is rotated to a certain position, the limit plate 28 fits against the side wall of the limit groove 36, and then when the purification component 3 continues to rotate, the rotating component 2 rotates accordingly, so that the rotation angle of the rotating component 2 during the installation or disassembly of the purification component 3 is smaller.

[0063] Optionally, the difference between the width W1 of the limiting groove 36 and the width W2 of the limiting plate 28 is greater than or equal to 10 mm and less than 100 mm.

[0064] It is understandable that, in the process of assembling the purification member 3, the purification member 3 is switched from the disassembled state to the assembled state, and the purification member 3 can drive the rotating member 2 to rotate, so that the rotating member 2 is switched from the first position to the second position; in the process of disassembling the purification member 3, the purification member 3 is switched from the assembled state to the disassembled state, and the purification member 3 can drive the rotating member 2 to rotate, so that the rotating member 2 is switched from the second position to the first position. When the purification member 3 is in the assembled state, the rotating member 2 is located in the second position, and when the purification member 3 is in the disassembled state, the rotating member 2 is located in the first position.

[0065] It can be understood that the purification component 3 proposed in the present application is detachably connected to the base body 1, so that the purification component 3 can be replaced or repaired. Specifically, the purification component 3 can be replaced as a whole, or only the filter element 31 inside the purification component 3 can be replaced to ensure the reliability of water purification by the water purification component.

[0066] Optionally, when the rotating member 2 is in the first position, the liquid inlet 10 and the liquid outlet 12 are disconnected, and then when the purification member 3 is removed, the rotating member 2 is rotated at a smaller angle to achieve the disconnection of the liquid inlet 10, the liquid outlet 12 and the purification channel 20; or, when the rotating member 2 is in the first position, the liquid inlet 10 and the liquid outlet 12 are connected through the bypass channel 14, and then when the purification member 3 is removed, the rotating member 2 is rotated at a smaller angle to achieve the connection of the liquid inlet 10, the liquid outlet 12 and the bypass channel 14, which can also reduce the risk of leakage.

[0067] Optionally, the purification element 3 is rotatably matched with the seat body 1 .

[0068] like Figure 2 As shown, in some embodiments, optionally, along the axial direction of rotation of the rotating member 2 , the length H2 of the limiting plate 28 is less than or equal to the length H1 of the limiting groove 36 .

[0069] In this embodiment, the length H2 of the limit plate 28 is smaller than the length H1 of the limit groove 36. On the one hand, it can avoid the interference between the limit plate 28 and the limit groove 36 along the axial direction and affect the installation of the purification component 3. On the other hand, it can also make the limit plate 28 completely inserted into the limit groove 36, thereby making the rotating part 2 and the purification part 3 more compact along the axial direction, which is beneficial to reducing the overall length of the water purification component along the axial direction of the rotating part 2.

[0070] Optionally, when the rotating member 2 is located at the second position, the limiting plate 28 is completely inserted into the limiting groove 36 .

[0071] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, optionally, a notch 362 is provided at one end of the limiting groove 36 along the axial direction of the rotating member 2 , and the limiting plate 28 can be inserted into the limiting groove 36 through the notch 362 .

[0072] In this embodiment, a notch 362 is provided at one end of the limiting groove 36 along the axial direction of the rotating member 2. When the purification member 3 is installed, the limiting plate 28 can be inserted into the limiting groove 36 through the notch 362, and then the rotation of the rotating member 2 is realized by the rotation of the purification member 3, so that the connection between the limiting plate 28 and the limiting groove 36 is simple and reliable.

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

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

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

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

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

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

[0103] In this embodiment, a detachable handle 37 is provided on the purification component 3, so that the purification component 3 can be adapted to different installation scenarios. For example, when the purification component 3 is installed on the top or door of the refrigerator, at this time, the tail of the bottle of the purification component 3 can be grasped, and the handle 37 is not required. When the purification component 3 is installed horizontally, the user has no other contact position. In this scenario, the handle 37 is installed on the purification component 3, and the disassembly and assembly are achieved by grasping the handle 37. The purification component 3 proposed in this application can achieve lean manufacturing and realize differentiated usage scenarios with minimal material changes.

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

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

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

[0107] In this embodiment, the refrigeration equipment 8 also includes a first refrigeration chamber 80 and a second refrigeration chamber 82. The first refrigeration chamber 80 is provided with a water outlet 800, and the second refrigeration chamber 82 is provided with an ice-making section 820. The liquid outlet 12 is respectively connected to the water outlet 800 and the ice-making section 820, so that the liquid flows to the water outlet 800 and the ice-making section 820, respectively, to prepare cold water and ice cubes.

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

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

[0110] Specifically, the liquid inlet 10 is connected to a water supply part, such as an external faucet or a water tank assembly. When the purification part 3 is in an assembled state, the liquid flows from the liquid inlet 10 to the purification part 3, and after being filtered by the purification part 3, flows out from the liquid outlet 12, and then flows to the water outlet 800 and / or the ice making part 820 under the switching of the valve body.

[0111] Optionally, the refrigeration device 8 includes a refrigerator or a freezer.

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

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

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

[0115] When the water purification module is assembled with the socket, the long arm at the bottom of the rotating center rod (such as the limit plate 28) extends into the corresponding notch structure of the upper end cover (such as the limit groove 36). 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 liquid inlet and outlet of the rotating center rod are connected with the liquid inlet and outlet of the socket. Among them, the rotation angle of the rotating center rod can be adjusted by adjusting the width W1 of the notch structure and the width W2 of the long arm at the bottom of the rotating center rod, so as to realize the design that the rotation angle of the rotating center rod and the water purification module are the same or different.

[0116] When the water purification module reaches the end of its service life or is disassembled midway, the notch structure of the upper end cover drives the long arm at the bottom of the rotating center rod to rotate in the opposite direction by the same angle, thereby restoring the rotating center rod to the position where the bypass channel 14 is formed.

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

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

[0119] Alternatively, if Figure 7 As shown, in order to avoid the problem of water-stop failure caused by the local size of the water-stop slit being too large due to local shrinkage in the injection molding process, the upper end cover can be reinforced, such as adding reinforcing ribs 35. Specifically, a cavity is provided between the outer wall of the upper end cover and the liquid outlet channel 320, and reinforcing ribs 35 are provided in the cavity. The material consumption can be reduced by setting the cavity, and the structural strength of the upper end cover can be improved by setting the reinforcing ribs 35. Therefore, during the molding process of the upper end cover, 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 33, so that the purification component 3 can fully filter the liquid and ensure the filtering effect of the liquid. Among them, the upper end cover is an injection molded part.

[0120] Optionally, in addition to controlling the assembly clearance between the upper end cover and the purification element 3 to be within 1 mm, a slit with a clearance within 1 mm can be designed on the upper end cover to increase the water flow area and prevent clogging in actual use. Specifically, Figure 8 As shown, a slit 38 is provided on the connecting column 324, and the slit 38 is located on the peripheral side of the liquid outlet channel 320, and one end of the slit 38 passes through the side wall of the connecting column 324 to connect the slit 38 with the water-stop slit (for example, the liquid inlet channel 33), wherein the slit 38 and the water-stop slit are used to form a water film to stop water when the purification component 3 is in a disassembled state.

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

[0122] The water purification component proposed in the present application drives the rotating center rod to rotate during the water purification module installation process, thereby realizing the switching from the bypass channel 14 to the purification channel 20, without the need for additional operations, thus saving time and effort.

[0123] 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.

[0124] Optionally, the notch structure may also be a groove or the like.
