Description

Technical Field

[0001] This invention relates to the field of packaging structure technology, specifically to the packaging structure of a water purifier. Background Technology

[0002] As the integration of functions in water purifiers increases, their structures become increasingly complex. Water purifiers include moving parts such as a raw water tank, a purified water pitcher, and an ice storage compartment, as well as vulnerable parts like the glass panel. Current packaging typically uses foam that conforms to the machine's contours. However, for vulnerable parts like the glass panel, during transport vibrations or compression, external impact forces can be directly transmitted to these points through rigid contact, causing localized stress concentration and easily leading to glass breakage. Summary of the Invention

[0003] In view of this, the present invention provides a packaging structure for a water purifier to solve the problem that the glass of a water purifier is easily broken under transportation vibration or compression in the prior art.

[0004] This invention provides a packaging structure for a water purifier. The water purifier includes a body, a purified water pitcher, a raw water tank, and a glass panel. The packaging structure includes: The lower foam component is suitable for being installed at the bottom of the water purifier to support and protect the bottom of the machine body and the pure water jug; An upper foam component is adapted to be installed on the upper part of the water purifier to limit and protect the top of the machine body, the raw water tank and the glass panel. The upper foam component is provided with support strips at the two side edges and the top frame of the front of the glass panel. The support strips contact the two side edges and the top frame of the front of the glass panel respectively. The upper foam component is provided with clearance from the rest of the glass panel.

[0005] Beneficial effects: The upper foam component simultaneously provides limiting protection for the top of the machine body, the raw water tank, and the glass panel, while the lower foam component supports and protects the bottom of the machine body and the pure water kettle. The upper and lower foam components work together to limit the movement of the water purifier body, the detachable raw water tank, the pure water kettle, and other moving parts inside the packaging box, preventing the raw water tank and pure water kettle from moving or shifting inside the box during transportation vibrations. Support strips are provided on the upper foam component corresponding to the two side edges and the top frame of the front of the glass panel. The support strips contact the two side edges and the top frame of the front of the glass panel respectively. The upper foam component is set to avoid gaps with the rest of the glass panel. During transportation, when the packaging structure is subjected to external impacts such as vibration, drop, or side compression, the impact force from the upper foam component will only act on the two side edges and the top frame of the front of the glass panel, which are structurally stronger. This can avoid the impact force acting on the vulnerable areas such as the middle, two sides, and the top surface of the glass panel, thereby avoiding the local stress concentration caused by rigid external impacts on the middle, two sides, and the top surface of the glass panel, and greatly reducing the probability of the glass panel cracking or bursting due to compression.

[0006] In one optional embodiment, the gap between the two sides of the glass panel and the upper foam component is h1, where 8mm ≤ h1 ≤ 15mm; And / or, the gap between the top surface of the glass panel and the upper foam component is h2, 5mm≤h2≤8mm; And / or, the gap between the center of the front of the glass panel and the upper foam component is h3, where 8mm ≤ h3 ≤ 15mm.

[0007] Beneficial effects: If the gap between the two sides of the glass panel and the upper foam component is less than 8mm, the space between the upper foam component and the sides of the glass panel is insufficient. When the packaging structure is subjected to lateral compression, the upper foam component is prone to pressing against the side of the glass panel, causing the lateral impact force to be transmitted to the side of the glass panel, resulting in cracking of the glass panel. If the gap between the two sides of the glass panel and the upper foam component is greater than 15mm, the machine body is prone to lateral movement within the upper foam component during transport bumps, and the upper foam component is prone to becoming too large in the lateral direction. Therefore, the gap is limited to 8mm≤h1≤15mm, which provides sufficient buffer travel between the two sides of the glass panel and the upper foam component. When the sides of the packaging structure are compressed and deformed, the upper foam component deforms within the buffer space, and the deformed upper foam component will not contact and compress the sides of the glass panel. At the same time, it prevents the machine body from lateral movement due to excessive gap and avoids the upper foam component becoming too large in the lateral direction.

[0008] If the gap between the top surface of the glass panel and the upper foam component is less than 5mm, the top surface of the glass panel is prone to impacting the upper foam component during a drop, causing the glass panel to crack. If the gap is greater than 8mm, the entire machine is prone to vertical movement. Therefore, limiting the gap to 5mm ≤ h2 ≤ 8mm allows for a buffer space between the top surface of the glass panel and the upper foam component. When the top of the packaging structure is impacted, the upper foam component deforms within the buffer space, preventing it from contacting and pressing against the top surface of the glass panel. Simultaneously, it prevents excessive gaps from causing vertical movement of the machine.

[0009] If the gap between the center of the front of the glass panel and the upper foam component is less than 8mm, when the packaging structure is compressed, the upper foam component, after slight deformation, can easily come into contact with the vulnerable area in the center of the glass panel. The impact force is directly applied to this vulnerable area, easily causing stress concentration and resulting in cracking of the glass panel. If the gap between the center of the front of the glass panel and the upper foam component is greater than 15mm, the upper foam component is likely to be too large in the front-to-back direction, increasing packaging material consumption and logistics and warehousing costs. Therefore, limiting the gap to 8mm≤h3≤15mm provides sufficient buffer space between the center of the front of the glass panel and the upper foam component. When the front of the packaging structure is compressed and deformed, the upper foam component deforms within the buffer space, and the deformed upper foam component will not come into contact with the front of the compressed glass panel. At the same time, it avoids the upper foam component being too large in the front-to-back direction, thus preventing additional increases in logistics costs.

[0010] In one optional embodiment, the water purifier further includes an ice storage compartment, the ice storage compartment is provided with a first handle, and the upper foam component is provided with first support ribs on both sides of the first handle, the two first support ribs clamping the first handle on both sides of the first handle.

[0011] Beneficial effects: The water purifier also includes an ice storage compartment, which is a detachable movable part on the upper part of the water purifier. During long-distance transportation and sudden braking, the ice storage compartment is prone to swaying back and forth inside the packaging box, potentially causing it to detach from the machine body. Therefore, by providing two first support ribs on either side of the first handle on the upper foam component, the two first support ribs clamp the first handle on both sides, limiting the displacement of the first handle in the pulling direction and preventing the ice storage compartment from sliding outwards. Simultaneously, because the two first support ribs clamp the first handle on both sides, they also limit the lateral swaying of the ice storage compartment.

[0012] In one optional embodiment, the water purifier packaging structure further includes a packaging box, the upper foam component and the lower foam component are adapted to be inserted into the packaging box, the upper foam component is in contact with the front of the first handle, and a cavity is provided on the side away from the first handle, the cavity being recessed toward the side away from the packaging box.

[0013] Beneficial Effects: The first handle is a cantilevered protrusion extending outward from the ice storage compartment. The root of the cantilever is a weak point in stress. If the upper foam component does not have a recessed cavity, meaning it contacts the side wall of the packaging box, when the front of the packaging box is subjected to pressure or drop impact, the impact force is easily transmitted to the first handle through the upper foam component. This concentrated impact force is then transmitted to the root of the first handle where it connects to the ice storage compartment, easily causing stress concentration at the root of the first handle, leading to injection molding cracks or even breakage. Therefore, by providing a recessed cavity in the upper foam component, when the front of the packaging box undergoes slight deformation under impact, it will not come into contact with the upper foam component, preventing the front impact force from being transmitted to the first handle through the upper foam component, effectively avoiding the problem of the first handle being damaged by pressure.

[0014] In one optional embodiment, the depth of the cavity is h4, where 10mm ≤ h4 ≤ 15mm.

[0015] Beneficial effects: If the depth of the cavity is less than 10mm, after the front of the packaging structure is impacted, the impact force on the packaging box is easily transmitted to the first handle through the upper foam component, which can easily lead to stress concentration at the root of the first handle, causing root cracking or even breakage. If the depth of the cavity is greater than 15mm, the upper foam component needs to provide a larger cavity on the front, resulting in an excessively large size of the packaging structure in the front-to-back direction, thereby increasing the outer packaging volume and increasing warehousing and logistics transportation costs. Alternatively, the thickness of the upper foam component at the front of the first handle may be too thin, resulting in weak protection for the first handle. Therefore, limiting the depth to 10mm≤h4≤15mm allows for sufficient buffer space between the front of the upper foam component and the packaging box. When the front of the packaging structure is impacted, the impact force on the front of the packaging box is less likely to be transmitted to the first handle, avoiding stress concentration at the root of the first handle and preventing root cracking or even breakage. It also avoids an excessively large size of the upper foam component in the front-to-back direction, thus avoiding additional logistics cost increases, or weak protection for the first handle.

[0016] In one optional embodiment, the upper foam component is provided with limiting ribs on the side wall of the raw water tank that does not contact the body. The thickness of the limiting ribs gradually increases from bottom to top. The interference fit between the bottom of the limiting rib and the outer edge of the raw water tank is w1, and the interference fit between the top of the limiting rib and the outer edge of the raw water tank is w2, where w1 < w2.

[0017] Beneficial effects: During assembly, the upper foam component is fitted onto the outside of the water purifier from top to bottom. Limiting ribs are provided on both sides of the upper foam component corresponding to the raw water tank. The thickness of the limiting ribs gradually increases from bottom to top. During assembly, the bottom end of the limiting rib first contacts the side wall of the raw water tank. At this point, there is a small interference fit between the bottom end of the limiting rib and the side wall of the raw water tank, facilitating the smooth entry of the raw water tank into the upper foam component. As the upper foam component continues to be pressed downwards, the thickness of the limiting rib increases further, and the interference fit gradually increases, effectively clamping the raw water tank and preventing the large-capacity raw water tank from shaking, shifting, or the lid from loosening under severe vibrations during transportation. Therefore, by gradually increasing the thickness of the limiting ribs from bottom to top, the interference fit between the bottom of the limiting rib and the outer edge of the raw water tank is w1, and the interference fit between the top of the limiting rib and the outer edge of the raw water tank is w2, where w1 < w2. This achieves optimal limiting of the raw water tank without affecting assembly.

[0018] In one alternative implementation, 0.5mm≤w1≤1mm, 1mm≤w2≤2mm; And / or, the length of the limiting rib is L, 10mm≤L≤20mm; And / or, the height of the limiting rib is h5, where h5 is 1 / 4 to 1 / 3 of the height of the original water tank.

[0019] Beneficial effects: If w1 < 0.5mm, the bottom interference is too small. During the pressing of the upper foam component, the limiting ribs cannot properly cooperate with the raw water tank to guide it. The upper foam component is prone to lateral displacement and cannot smoothly slide into the preset position. It may even scratch the machine body or the outer wall of the raw water tank due to misalignment. If w1 > 1mm, the initial bottom interference is too large. The upper foam component will generate a large lateral clamping resistance to the raw water tank as soon as it is pressed down. The resistance of the upper foam component pressing down is large, and the outer wall of the raw water tank is prone to denting and deformation due to long-term high extrusion pressure. Therefore, by limiting 0.5mm ≤ w1 ≤ 1mm, it can provide guidance for the pressing of the upper foam component and reduce the pressing resistance, preventing the outer wall of the raw water tank from denting and deforming due to long-term high extrusion pressure.

[0020] If w2 < 1mm, the top of the limiting rib cannot provide sufficient clamping force to restrain the raw water tank, making it prone to shaking. If w2 > 2mm, the interference fit at the top of the limiting rib is too large, and the upper outer wall of the raw water tank is prone to permanent indentation and concave deformation due to long-term pressure. Therefore, by limiting w2 to 1mm ≤ w2 ≤ 2mm, sufficient clamping force can be provided for the raw water tank, while avoiding permanent indentation and concave deformation caused by long-term pressure on the upper outer wall of the raw water tank.

[0021] If L < 10mm, the horizontal contact area between the limiting rib and the side wall of the raw water tank is too small, making the side wall prone to indentation due to excessive pressure. Simultaneously, the narrower limiting rib provides weaker clamping stability for the raw water tank, making clamping prone to slippage and failure. If L > 20mm, the horizontal width of the limiting rib is too long, resulting in excessive space occupied by the rib within the upper foam component, leading to greater resistance during press-fitting. Therefore, by limiting L to 10mm ≤ L ≤ 20mm, both clamping stability for the raw water tank is ensured, reducing the likelihood of clamping failure, and excessive resistance is avoided for the upper foam component during press-fitting.

[0022] If h5 is less than 1 / 4 of the height of the original water tank, the vertical contact area between the limiting rib and the side wall of the original water tank is too small. This can easily cause indentations on the side wall due to excessive pressure. Furthermore, a shorter limiting rib provides weaker clamping stability to the original water tank, making it prone to slippage and failure. If h5 is greater than 1 / 3 of the height of the original water tank, the vertical length of the limiting rib is too long, resulting in continuous significant resistance to the upper foam component during pressing. Therefore, limiting h5 to 1 / 4-1 / 3 of the height of the original water tank ensures both clamping stability and prevents clamping failure, while also avoiding continuous significant resistance to the upper foam component during pressing.

[0023] In one optional embodiment, the upper foam component has two limiting ribs on each of its two opposite sidewalls, and the two limiting ribs on the same sidewall are arranged at intervals in the horizontal direction, and a groove is formed between the two limiting ribs on the same sidewall.

[0024] Beneficial effects: The upper foam component has two limiting ribs on each of its two opposite sidewalls, and the two limiting ribs on the same sidewall are arranged at intervals in the horizontal direction, and a groove is formed between the two limiting ribs on the same sidewall. The raw water tank contacts the limiting ribs on both sides, and the groove does not contact the raw water tank. This can reduce the frictional resistance when pressing the foam component, and at the same time ensure the clamping stability of the raw water tank.

[0025] In one optional embodiment, a plug limiting groove is provided on the top side of the upper foam component, and a first wire guide groove is provided at the bottom of the plug limiting groove. The power cord is adapted to be embedded in the first wire guide groove, and the plug connected to the power cord is adapted to be limited in the plug limiting groove.

[0026] Beneficial effects: By setting a plug limiting groove on the top side of the upper foam part, and a first wire passing groove at the bottom of the plug limiting groove, the power cord is embedded in the first wire passing groove, and the plug connected to the power cord is limited in the plug limiting groove, which restricts the power cord and plug from moving around and causing the plug prongs to bend, break or cause scratches on the machine body.

[0027] In one optional embodiment, the plug limiting groove includes a first groove segment and a second groove segment. The first groove segment is lower than the second groove segment to form a stepped surface between the first groove segment and the second groove segment. The first groove segment is provided with an arc-shaped rib. The arc-shaped rib is located at the top of the first wire guide groove. The plug includes a plug body and a prong. The plug body is disposed on the arc-shaped rib and abuts against the stepped surface. The prong is located in the second groove segment.

[0028] Beneficial effects: The plug limiting groove includes a first groove segment and a second groove segment. The first groove segment is lower than the second groove segment to form a stepped surface between the first groove segment and the second groove segment. The first groove segment is provided with an arc-shaped rib, which is located at the top of the first wire guide groove. The plug includes a plug body and a prong. The plug body is located on the arc-shaped rib and abuts against the stepped surface. It is set in the first wire guide groove in conjunction with the power cord. This can achieve constraint on all directions of the plug except the top, completely eliminating the plug from moving during transportation and preventing the prong from bending, breaking or causing scratches on the machine body.

[0029] In one alternative embodiment, on a projection plane parallel to the side opening, the projected height of the arc-shaped rib is h6, and h6 is not less than 1 / 3 of the outer diameter of the plug body.

[0030] Beneficial effect: By ensuring that the projected height of the arc-shaped rib is not less than 1 / 3 of the outer diameter of the plug body on the projection plane parallel to the side opening, reliable positioning of the plug can be further ensured.

[0031] In one alternative embodiment, the water purifier packaging structure further includes a packaging box, the upper foam component and the lower foam component being adapted to be placed inside the packaging box, and the packaging box being adapted to limit the top of the plug body.

[0032] Beneficial effects: The packaging box is fitted outside the upper and lower foam components. The top wall of the packaging box applies a limiting constraint from the top of the plug body. The plug is clamped between the bottom of the lower plug limiting groove and the upper packaging box top wall, and vertical displacement is locked in both directions. The plug cannot jump upward and dislodge from the plug limiting groove, preventing the plug from sliding freely inside the packaging box, swinging, and impacting vulnerable parts such as the glass panel and the water tank after it jumps out.

[0033] In one alternative embodiment, the top of the upper foam component is provided with an accessory storage slot; and / or, the upper foam component is provided with an exhaust vent.

[0034] Beneficial effects: The accessory storage slot on the top of the upper foam component facilitates the placement of various accessories for the water purifier tank. The vent hole on the upper foam component allows for rapid expulsion of air between the upper foam component and the water purifier during press-fitting, reducing pressing resistance.

[0035] In one optional embodiment, the lower foam component is provided with second support ribs on both sides of the front of the pure water bottle, and the second support ribs have L-shaped support surfaces that contact the front and side of the pure water bottle respectively.

[0036] Beneficial effects: By setting a second support rib on the lower foam part, the second support rib has an L-shaped support surface that contacts the front and side of the pure water bottle respectively, which can limit and constrain the front and left and right sides of the pure water bottle, effectively preventing the pure water bottle from shaking or falling off the machine body.

[0037] In one optional embodiment, the front of the water bottle is provided with a second handle, and the lower foam component is disposed away from the second handle.

[0038] Beneficial Effects: The second handle is a cantilevered protrusion extending from the ice storage compartment. The root of the cantilever is a weak point in stress. If the lower foam component is completely flush with the front of the second handle, when the front of the packaging box is squeezed or subjected to impact from a drop, the lower foam component deforms under external force and directly impacts the second handle from the front. The impact force is concentrated and transmitted to the root of the handle where it connects to the ice storage compartment, easily causing stress concentration at the handle root, resulting in injection molding cracks or even breakage. Therefore, by creating a gap between the front of the lower foam component and the second handle, the front of the lower foam component will not come into contact with the handle when subjected to slight deformation under impact, preventing the front impact force from being transmitted to the second handle through the lower foam component, effectively avoiding the problem of pressure damage to the front of the second handle.

[0039] In one optional embodiment, the gap between the lower foam component and the left side or the right side of the second handle is w3, where 10mm≤w3≤20mm; And / or, the gap between the lower foam component and the bottom of the second handle is w4, 15mm≤w4≤25mm.

[0040] Beneficial effects: If the gap between the lower foam component and the left or right side of the second handle is less than 10mm, after the side of the packaging structure is impacted, the lower foam component, after undergoing slight deformation under pressure, is prone to contacting the left or right side of the second handle, which can easily lead to stress concentration at the root of the second handle, causing root cracking or even breakage. If the gap between the lower foam component and the left or right side of the second handle is greater than 20mm, the lower foam component creates a larger cavity on both sides of the second handle, resulting in an excessively large lateral dimension of the packaging structure, thereby increasing the outer packaging volume and raising warehousing and logistics costs. Therefore, by limiting the gap to 10mm≤w3≤20mm, sufficient buffer space can be reserved between the side of the second handle and the lower foam component. When the side of the packaging structure is impacted, the lower foam component, after undergoing slight deformation under pressure, will not contact the side of the second handle, avoiding stress concentration at the root of the second handle and preventing root cracking or even breakage. Furthermore, the excessive lateral dimension of the lower foam component avoids additional logistics cost increases.

[0041] If the gap between the lower foam component and the bottom of the second handle is less than 15mm, after the packaging structure is subjected to a drop impact, the lower foam component will deform slightly upwards and easily come into contact with the bottom of the second handle, potentially causing stress concentration at the base of the second handle, leading to cracking or even breakage. If the gap between the lower foam component and the bottom of the second handle is greater than 25mm, the lower foam component needs to create a larger cavity below the second handle, resulting in an excessively large dimension of the packaging structure in the height direction, thus increasing the outer packaging volume and raising warehousing and logistics costs. Therefore, limiting the gap to 15mm ≤ w4 ≤ 25mm allows for sufficient buffer space between the bottom of the second handle and the lower foam component. When the packaging structure is subjected to a drop impact, the lower foam component will deform slightly upwards and not come into contact with the bottom of the second handle, avoiding stress concentration at the base of the second handle and preventing cracking or breakage. It also avoids an excessively large dimension of the lower foam component in the height direction, thus preventing additional increases in logistics costs.

[0042] In one optional embodiment, the lower foam component is provided with handle positions on both sides; And / or, a second wire guide groove is provided on one side of the lower foam component, the second wire guide groove being opposite to the first wire guide groove.

[0043] Beneficial effects: By providing handles on both sides of the lower foam component, the user can easily remove the entire machine. A second cable guide groove is provided on one side of the lower foam component, opposite to the first cable guide groove, which allows the power cord to be smoothly connected from the second cable guide groove to the first cable guide groove on the upper foam component.

[0044] In one optional embodiment, the water purifier packaging structure further includes a packaging box and a base tray. The upper foam component and the lower foam component are adapted to be placed inside the packaging box. The base tray is located at the bottom of the packaging box and is used to support the lower foam component. The lower foam component and the base tray are positioned by a positioning structure.

[0045] Beneficial effects: By setting a base, the lower foam component can be prevented from directly contacting the bottom of the packaging box, thus avoiding its vulnerability to impacts from drops. The positioning structure between the lower foam component and the base ensures a secure connection between them. Attached Figure Description

Detailed Implementation

[0049] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0051] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0052] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0053] As the integration of functions in water purifiers increases, their structures become increasingly complex. Water purifiers include moving parts such as a raw water tank, a purified water pitcher, and an ice storage compartment, as well as vulnerable parts like the glass panel. Current packaging typically uses foam that conforms to the machine's contours. However, for vulnerable parts like the glass panel, during transport vibrations or compression, external impact forces can be directly transmitted to these points through rigid contact, causing localized stress concentration and easily leading to glass breakage.

[0054] In addition, existing packaging technologies still use tape wrapped around the foam. The tape wrapping process is cumbersome and time-consuming, making it difficult to adapt to modern automated packaging lines, increasing labor costs, and leaving tape residue that affects the packaging's appearance and makes unpacking and cleaning difficult.

[0055] The following is combined with Figures 1 to 14 The following describes embodiments of the present invention.

[0056] According to embodiments of the present invention, a packaging structure for a water purifier is provided, such as... Figure 1 As shown, the water purifier includes a body 1, a pure water pitcher 2, a raw water tank 3, and a glass panel 4. The packaging structure of the water purifier includes a lower foam component 7 and an upper foam component 6.

[0057] The lower foam component 7 is suitable for placement at the bottom of the water purifier to support and protect the bottom of the body 1 and the pure water jug ​​2; the upper foam component 6 is suitable for placement at the top of the water purifier to limit and protect the top of the body 1, the raw water tank 3, and the glass panel 4. Figure 2 and Figure 8 , Figure 9 The upper foam component 6 is provided with support strips 601 on the two sides and the top frame of the front of the glass panel 4. The support strips 601 contact the two sides and the top frame of the front of the glass panel 4 respectively. The upper foam component 6 is provided with a gap between itself and the rest of the glass panel 4.

[0058] In the above embodiment, the upper foam component simultaneously provides limiting protection for the top of the body 1, the raw water tank 3, and the glass panel 4, while the lower foam component 7 provides support and protection for the bottom of the body 1 and the pure water kettle 2. The upper foam component 6 and the lower foam component 7 work together to limit the movement of the water purifier body 1, the detachable raw water tank 3, the pure water kettle 2, and other moving parts inside the packaging box 9, preventing the raw water tank 3 and the pure water kettle 2 from moving or shifting inside the box during transportation vibration. Support strips 601 are provided on the upper foam component 6 corresponding to the two side edges and the top frame of the front of the glass panel 4. The support strips 601 contact the two side edges and the top frame of the front of the glass panel 4 respectively. The upper foam component 6 is provided to avoid gaps in the other positions of the glass panel 4. During transportation, when the packaging structure is subjected to external force impacts such as vibration, drop, or side compression, the impact force from the upper foam component 6 will only act on the two side edges and the top frame of the front of the glass panel 4, which are structurally stronger. This can prevent the impact force from acting on the vulnerable areas such as the middle, two sides, and the top surface of the glass panel 4, thereby avoiding the local stress concentration caused by rigid impacts of external forces on the middle, two sides, and the top surface of the glass panel 4, and greatly reducing the probability of cracks and explosions caused by the glass panel 4 being squeezed.

[0059] In the above embodiments, utilizing the high structural strength of the two side edges and top frame of the front side of the glass panel 4, the support strips 601 of the upper foam component 6 support these parts, while the remaining positions are open. When the upper foam component 6 is compressed and deformed, the open areas provide a deformation buffer space, which can absorb transportation vibrations and improve the overall vibration resistance of the packaging structure. In addition, since the upper foam component 6 only has support strips 601 at the two side edges and top frame of the front side of the glass panel 4, and the remaining positions are open to the glass panel 4, the amount of foam material used can be effectively reduced, thereby reducing packaging material costs and product weight, which is conducive to lightweight packaging structure.

[0060] Specifically, since the support strip 601 contacts the two side edges and the top frame of the front of the glass panel 4 respectively, the support strip 601 is in an inverted U shape.

[0061] It should be noted that the top bezel specifically refers to the top bezel of the front of the glass panel 4.

[0062] Based on the above embodiments, as a further defined implementation method, combined with... Figure 2 and Figure 3 The gap between the two sides of the glass panel 4 and the upper foam component 6 is h1, 8mm≤h1≤15mm; and / or, the gap between the top surface of the glass panel 4 and the upper foam component 6 is h2, 5mm≤h2≤8mm; and / or, combined with Figure 4 The gap between the center of the front of the glass panel 4 and the upper foam component 6 is h3, where 8mm ≤ h3 ≤ 15mm.

[0063] In the above embodiments, if the gap between the two sides of the glass panel 4 and the upper foam component 6 is less than 8mm, the space between the upper foam component 6 and the sides of the glass panel 4 is insufficient. When the packaging structure is subjected to lateral compression, the upper foam component 6 is prone to pressing against the side of the glass panel 4, causing the lateral impact force to be transmitted to the side of the glass panel 4, resulting in cracking of the glass panel 4. If the gap between the two sides of the glass panel 4 and the upper foam component 6 is greater than 15mm, the body 1 is prone to lateral movement within the upper foam component 6 during transport bumps, and the upper foam component 6 is prone to becoming too large in the lateral direction. Therefore, the gap is limited to 8mm≤h1≤15mm, which provides sufficient buffer travel between the two sides of the glass panel 4 and the upper foam component 6. When the side of the packaging structure is compressed and deformed, the upper foam component 6 deforms within the buffer space, and the deformed upper foam component 6 will not contact the side of the compressed glass panel 4. At the same time, it prevents the body 1 from lateral movement due to excessive gap and avoids the upper foam component 6 becoming too large in the lateral direction.

[0064] If the gap between the top surface of the glass panel 4 and the upper foam component 6 is less than 5mm, the top surface of the glass panel 4 is likely to hit the upper foam component 6 under drop impact, causing the glass panel 4 to crack. If the gap between the top surface of the glass panel 4 and the upper foam component 6 is greater than 8mm, it is likely to cause the entire machine to move up and down. Therefore, limiting the gap to 5mm≤h2≤8mm allows for a buffer space between the top surface of the glass panel 4 and the upper foam component 6. When the top of the packaging structure is impacted, the upper foam component 6 deforms within the buffer space, and the deformed upper foam component 6 will not contact or compress the top surface of the glass panel 4. At the same time, it prevents the machine body 1 from moving up and down due to an excessively large gap.

[0065] If the gap between the center of the front of the glass panel 4 and the upper foam component 6 is less than 8mm, when the packaging structure is compressed, the upper foam component 6, after slight deformation, can easily come into contact with the vulnerable area in the center of the glass panel 4. The impact force is directly applied to this vulnerable area, which can easily cause stress concentration and lead to cracking of the glass panel 4. If the gap between the center of the front of the glass panel 4 and the upper foam component 6 is greater than 15mm, the upper foam component 6 is likely to be too large in the front-to-back direction, increasing packaging material consumption and logistics and warehousing costs. Therefore, the gap is limited to 8mm≤h3≤15mm. This provides sufficient buffer space between the center of the front of the glass panel 4 and the upper foam component 6. When the front of the packaging structure is compressed and deformed, the upper foam component 6 deforms within the buffer space and will not come into contact with the front of the compressed glass panel 4. At the same time, it avoids the upper foam component 6 being too large in the front-to-back direction, thus preventing additional increases in logistics costs.

[0066] In a preferred embodiment, 8mm≤h1≤15mm, 5mm≤h2≤8mm, and 8mm≤h3≤15mm.

[0067] It should be noted that, since the body 1 on the top side of the glass panel 4 has high strength, even if the upper foam 6 deforms less when subjected to force, the upper foam 6 is not easy to contact the top surface of the glass panel 4 after deformation. Therefore, the value of h2 is smaller than that of h1 and h3.

[0068] Based on the above embodiments, as a further defined implementation, the water purifier also includes an ice storage compartment 5, which is equipped with a first handle 501, combined with... Figure 8 The upper foam component 6 is provided with first support ribs 602 on both sides of the first handle 501, and the two first support ribs 602 clamp the first handle 501 on both sides of the first handle 501.

[0069] In the above embodiment, the water purifier also includes an ice storage compartment 5. The ice storage compartment 5 is a detachable movable part on the upper part of the water purifier. During long-distance transportation and sudden braking, it is prone to swaying back and forth inside the packaging box 9, causing it to detach from the machine body 1. Therefore, by providing first support ribs 602 on both sides of the upper foam part 6 corresponding to the first handle 501, the two first support ribs 602 clamp the first handle 501 on both sides, which can limit the displacement of the first handle 501 in the pulling direction and prevent the ice storage compartment 5 from sliding outward. At the same time, since the two first support ribs 602 clamp the first handle 501 on both sides, the swaying of the ice storage compartment 5 in the left and right directions can also be limited.

[0070] Specifically, the first support rib 602 and the first handle 501 are interference fit.

[0071] Based on the above embodiments, as a further defined implementation, the water purifier packaging structure also includes a packaging box 9, with the upper foam component 6 and the lower foam component 7 adapted to be placed inside the packaging box 9. The upper foam component 6 is in contact with the front of the first handle 501, and as shown... Figure 4 As shown, the upper foam part 6 has a recess 609 on the side away from the first handle 501, and the recess 609 is recessed towards the side away from the packaging box 9.

[0072] In the above embodiment, the first handle 501 is a cantilevered protrusion extending outward from the ice storage compartment 5. The root of the cantilever is a stress-weak point. If the upper foam component 6 does not have a recess 609, that is, if the upper foam component 6 is in contact with the side wall of the packaging box 9, when the front of the packaging box 9 is squeezed or dropped, the impact force on the packaging box 9 can easily be transmitted to the first handle 501 through the upper foam component 6. The impact force is concentrated and transmitted to the root position where the first handle 501 connects to the ice storage compartment 5, which can easily cause stress concentration at the root of the first handle 501, resulting in injection molding cracks or even breakage failure. Therefore, by providing a recess 609 in the upper foam component 6, when the front of the packaging box 9 undergoes slight deformation under impact, it will not come into contact with the upper foam component 6, avoiding the front impact force from being transmitted to the first handle 501 through the upper foam component 6, effectively avoiding the problem of the first handle 501 being damaged by pressure.

[0073] In the above embodiment, the upper foam component 6 uses the first support ribs 602 on both sides to clamp and position the left and right sides of the first handle 501, thus restraining the lateral movement of the ice storage compartment 5. The upper foam component 6 is in contact with the front of the first handle 501, which can prevent the ice storage compartment 5 from moving forward and leaving the body 1. Under the conditions of transportation bumps and multi-directional compound impact, it can reliably limit the left and right swing and back and forth sway of the ice storage compartment 5. When the front of the packaging box 9 is subjected to a slight deformation due to the impact force, it will not come into contact with the upper foam component 6, thus avoiding the front impact force from being transmitted to the first handle 501 through the upper foam component 6, effectively avoiding the problem of the front of the first handle 501 being damaged by pressure.

[0074] Based on the above embodiments, as a further defined implementation, the depth of the cavity 609 is h4, where 10mm≤h4≤15mm.

[0075] In the above embodiments, if the depth of the cavity 609 is less than 10mm, after the front of the packaging structure is impacted, the impact force on the packaging box 9 is easily transmitted to the first handle 501 through the upper foam 6, which can easily lead to stress concentration at the root of the first handle 501 and cause root cracking or even breakage. If the depth of the cavity 609 is greater than 15mm, the upper foam 6 needs to make a larger cavity on the front, resulting in an excessively large size of the packaging structure in the front-back direction, thereby increasing the volume of the outer packaging and increasing warehousing and logistics transportation costs. Alternatively, the upper foam 6 may be thinner at the front of the first handle 501, resulting in weaker protection for the first handle 501. Therefore, limiting the size to 10mm≤h4≤15mm allows for sufficient buffer space between the front of the upper foam component 6 and the packaging box 9. When the front of the packaging structure is impacted, the impact force on the front of the packaging box 9 is not easily transmitted to the first handle 501, thus avoiding stress concentration at the root of the first handle 501 and causing root cracking or even breakage. It also avoids the upper foam component 6 being too large in the front-back direction, which would not lead to additional logistics costs or weak protection for the first handle 501.

[0076] Based on the above embodiments, as a further defined implementation method, combined with... Figures 5 to 9 The upper foam part 6 is provided with limiting ribs 603 on the side wall of the original water tank 3 that does not contact the body 1. The thickness of the limiting ribs 603 gradually increases from bottom to top. The interference fit between the bottom of the limiting ribs 603 and the outer edge of the original water tank 3 is w1, and the interference fit between the top of the limiting ribs 603 and the outer edge of the original water tank 3 is w2, where w1 < w2.

[0077] In the above embodiment, during assembly, the upper foam part 6 is fitted onto the outside of the water purifier from top to bottom. Limiting ribs 603 are provided on the side wall of the upper foam part 6 corresponding to the original water tank 3 that does not contact the body 1. The thickness of the limiting ribs 603 gradually increases from bottom to top. During assembly, the bottom end of the limiting rib 603 first contacts the side wall of the original water tank 3. At this time, there is a small interference between the bottom end of the limiting rib 603 and the side wall of the original water tank 3, which facilitates the smooth entry of the original water tank 3 into the upper foam part 6. As the upper foam part 6 continues to be pressed down, the thickness of the limiting rib 603 increases further up, and the interference gradually increases, which can effectively clamp the original water tank 3 and effectively prevent the large-capacity original water tank 3 from shaking, shifting, or the lid from loosening under severe vibration during transportation. Therefore, by gradually increasing the thickness of the limiting rib 603 from bottom to top, the interference fit between the bottom of the limiting rib 603 and the outer edge of the original water tank 3 is w1, and the interference fit between the top of the limiting rib 603 and the outer edge of the original water tank 3 is w2, where w1 < w2, thus achieving a better limiting of the original water tank 3 without affecting the assembly.

[0078] Based on the above embodiments, as a further defined implementation, 0.5mm≤w1≤1mm, 1mm≤w2≤2mm; and / or, the length of the limiting rib 603 is L, 10mm≤L≤20mm; and / or, the height of the limiting rib 603 is h5, where h5 is 1 / 4-1 / 3 of the original height of the water tank 3.

[0079] In the above embodiments, if w1 < 0.5 mm, the bottom interference is too small. During the pressing of the upper foam part 6, the limiting rib 603 is difficult to cooperate with the original water tank 3 to play a guiding role. The upper foam part 6 is prone to left and right deviation and cannot slide smoothly into the preset position. It may even scratch the outer wall of the machine body 1 or the original water tank 3 due to misalignment. If w1 > 1 mm, the initial bottom interference is too large. The upper foam part 6 will generate a large lateral clamping resistance to the original water tank 3 as soon as it is pressed down. The resistance of the upper foam part 6 is large, and the outer wall of the original water tank 3 is prone to denting and deformation due to long-term large extrusion pressure. Therefore, by limiting 0.5 mm ≤ w1 ≤ 1 mm, it can not only provide a guiding role for the pressing of the upper foam part 6, but also reduce the pressing resistance and prevent the outer wall of the original water tank 3 from being dented and deformed due to long-term large extrusion pressure.

[0080] If w2 < 1 mm, the top of the limiting rib 603 cannot provide sufficient clamping force to restrain the raw water tank 3, and the raw water tank 3 is prone to shaking. If w2 > 2 mm, the interference at the top of the limiting rib 603 is too large, and the upper outer wall of the raw water tank 3 is prone to permanent indentation and concave deformation due to long-term pressure. Therefore, by limiting w2 to 1 mm ≤ w2 ≤ 2 mm, sufficient clamping force can be provided for the raw water tank 3, while avoiding permanent indentation and concave deformation due to long-term pressure on the upper outer wall of the raw water tank 3.

[0081] If L < 10mm, the horizontal contact area between the limiting rib 603 and the side wall of the original water tank 3 is too small, and the side wall of the original water tank 3 is prone to indentation due to excessive pressure. At the same time, the narrower limiting rib 603 provides weaker clamping stability for the original water tank 3, and the clamping is prone to slippage failure. If L > 20mm, the width of the limiting rib 603 in the horizontal direction is too long, resulting in the limiting rib 603 occupying too much space inside the upper foam part 6, and experiencing greater resistance during the pressing process. Therefore, by limiting L to 10mm ≤ L ≤ 20mm, the clamping stability of the original water tank 3 can be ensured, making clamping less prone to failure, while also avoiding excessive resistance to the upper foam part 6 during the pressing process.

[0082] If h5 is less than 1 / 4 of the height of the original water tank 3, the vertical contact area between the limiting rib 603 and the side wall of the original water tank 3 is too small. The side wall of the original water tank 3 is prone to indentation due to excessive pressure. At the same time, the shorter limiting rib 603 provides weaker clamping stability for the original water tank 3, and the clamping is prone to slippage failure. If h5 is greater than 1 / 3 of the height of the original water tank 3, the vertical length of the limiting rib 603 is too long, causing the upper foam part 6 to continuously experience significant resistance during the pressing process. Therefore, by limiting h5 to 1 / 4-1 / 3 of the height of the original water tank 3, the clamping stability of the original water tank 3 can be ensured, making clamping less prone to failure, while also avoiding the upper foam part 6 continuously experiencing significant resistance during the pressing process.

[0083] Based on the above embodiments, as a further defined implementation, each of the two opposite sidewalls of the upper foam component 6 is provided with two limiting ribs 603, and the two limiting ribs 603 on the same sidewall are arranged at intervals in the horizontal direction, and a groove 604 is formed between the two limiting ribs 603 on the same sidewall.

[0084] In the above embodiment, two limiting ribs 603 are provided on the two opposite sidewalls of the upper foam component 6, and the two limiting ribs 603 on the same sidewall are arranged at intervals in the horizontal direction, and a groove 604 is formed between the two limiting ribs 603 on the same sidewall. The original water tank 3 is in contact with the limiting ribs 603 on both sides, and the groove 604 is not in contact with the original water tank 3. This can reduce the frictional resistance when the foam component 6 is pressed on, and at the same time ensure the clamping stability of the original water tank 3.

[0085] Specifically, the raw water tank 3 includes a tank body and a tank cover 301. The tank cover 301 is located on the top of the tank body, and the upper foam component 6 limits the top of the tank cover 301 to prevent the tank cover 301 from detaching from the tank body.

[0086] Specifically, the body 1 is also provided with a water outlet 101, and the bottom end of the upper foam component 6 is located above the water outlet 101.

[0087] Based on the above embodiments, as a further defined implementation, a plug limiting groove 605 is provided on one side of the top of the upper foam component 6, and a first wire passing groove 606 is provided at the bottom of the plug limiting groove 605. The power cord 10 is adapted to be embedded in the first wire passing groove 606, and the plug 11 connected to the power cord 10 is adapted to be limited in the plug limiting groove 605.

[0088] In the above embodiment, by providing a plug limiting groove 605 on one side of the top of the upper foam 6, and providing a first wire passing groove 606 at the bottom of the plug limiting groove 605, the power cord 10 is embedded in the first wire passing groove 606, and the plug 11 connected to the power cord 10 is limited in the plug limiting groove 605, thus preventing the power cord 10 and the plug from moving around and causing the plug prongs 1102 to bend, break, or cause scratches on the body 1.

[0089] In one specific implementation, combined with Figure 10 The first wire groove 606 is inverted Y-shaped, and the opening at the lower end of the first wire groove 606 is relatively large.

[0090] In one specific embodiment, the plug limiting groove 605 has a top opening and a side opening, which facilitates inserting the plug into the plug limiting groove 605 and removing the plug from the limiting groove.

[0091] Based on the above embodiments, as a further defined implementation method, combined with... Figure 11 The plug limiting groove 605 includes a first groove segment 6051 and a second groove segment 6052. The first groove segment 6051 is lower than the second groove segment 6052 so that a stepped surface 6053 is formed between the first groove segment 6051 and the second groove segment 6052. The first groove segment 6051 is provided with an arc-shaped protrusion 60511, which is located at the top of the first wire guide groove 606. The plug 11 includes a plug body 1101 and a plug prong 1102. The plug body 1101 is disposed on the arc-shaped protrusion 60511 and abuts against the stepped surface 6053. The plug prong 1102 is located in the second groove segment 6052.

[0092] In the above embodiment, the plug limiting groove 605 includes a first groove segment 6051 and a second groove segment 6052. The first groove segment 6051 is lower than the second groove segment 6052 so that a stepped surface 6053 is formed between the first groove segment 6051 and the second groove segment 6052. The first groove segment 6051 is provided with an arc-shaped protrusion 60511, which is located at the top of the first wire guide groove 606. The plug includes a plug body 1101 and a prong 1102. The plug body 1101 is disposed on the arc-shaped protrusion 60511 and abuts against the stepped surface 6053. It is also arranged in the first wire guide groove 606 in conjunction with the power cord 10. This can achieve constraint on all directions of the plug except the top, completely preventing the plug 11 from moving during transportation and preventing the prong 1102 from bending, breaking, or causing scratches on the body 1.

[0093] Specifically, the outer surface of the plug body 1101 is circular, and the arc-shaped rib 60511 is adapted to the shape of the plug body 1101.

[0094] Based on the above embodiments, as a further defined implementation, on a projection plane parallel to the side opening, combined with... Figure 12 The projected height of the arc-shaped rib 60511 is h6, and h6 is not less than 1 / 3 of the outer diameter of the plug body 1101.

[0095] In the above embodiment, by ensuring that the projection height of the arc-shaped rib 60511 on the projection plane parallel to the side opening is not less than 1 / 3 of the outer diameter of the plug body 1101, reliable positioning of the plug can be further ensured.

[0096] Based on the above embodiments, as a further defined implementation, the water purifier packaging structure also includes a packaging box 9, with the upper foam component 6 and the lower foam component 7 adapted to be placed inside the packaging box 9, and the packaging box 9 adapted to limit the top of the plug body 1101.

[0097] In the above embodiment, the packaging box 9 is fitted outside the upper foam component 6 and the lower foam component 7. The top wall of the packaging box 9 applies a limiting constraint from the top of the plug body 1101. The plug is clamped between the bottom of the lower plug limiting groove 605 and the upper top wall of the packaging box 9, and vertical displacement is locked in both directions. The plug cannot jump upward and dislodge from the plug limiting groove 605, thus preventing the plug from sliding freely inside the packaging box 9 and swinging and hitting vulnerable parts such as the glass panel 4 and the raw water tank 3 after it pops out.

[0098] Based on the above embodiments, as a further defined implementation, the top of the upper foam component 6 is provided with an accessory storage groove 607; and / or, the upper foam component 6 is provided with an exhaust hole 608.

[0099] In the above embodiments, by providing an accessory storage slot 607 on the top of the upper foam component 6, it is convenient to place various accessories of the water purifier tank. By providing an exhaust hole 608 on the upper foam component 6, air between the upper foam component 6 and the water purifier can be quickly discharged during the pressing process, reducing pressing resistance.

[0100] Specifically, the accessory storage slot 607 can be used to store accessories such as instruction manuals, water storage boxes, and spoons.

[0101] Based on the above embodiments, as a further defined implementation method, combined with... Figure 13 The lower foam component 7 is provided with second support ribs 701 on both sides of the front of the pure water bottle 2. The second support ribs 701 have L-shaped support surfaces, which are in contact with the front and side of the pure water bottle 2 respectively.

[0102] In the above embodiment, by providing a second support rib 701 in the lower foam part 7, the second support rib 701 has an L-shaped support surface, which contacts the front and side of the pure water bottle 2 respectively, and can limit and constrain the front and left and right sides of the pure water bottle 2, effectively preventing the pure water bottle 2 from shaking and falling off the body 1.

[0103] Based on the above embodiments, as a further limiting implementation method, please refer to the following: Figure 13 The front of the pure water bottle 2 is provided with a second handle 201, and the lower foam part 7 is positioned to avoid gaps with the second handle 201.

[0104] In the above embodiment, the second handle 201 is a cantilevered protrusion extending outward from the ice storage compartment 5. The root of the cantilever is a weak stress point. If the lower foam component 7 is completely in contact with the front of the second handle 201, when the front of the packaging box 9 is squeezed or subjected to a drop impact, the lower foam component 7 will deform under external force and directly press against the second handle 201 from the front. The impact force will be concentrated and transmitted to the root position where the handle connects to the ice storage compartment 5, which can easily cause stress concentration at the root of the handle, resulting in injection molding cracks or even breakage failure. Therefore, by providing a frontal clearance between the lower foam component 7 and the second handle 201, the front of the lower foam component 7 will not come into contact with the handle when it undergoes slight deformation under impact, thus preventing the frontal impact force from being transmitted to the second handle 201 through the lower foam component 7, effectively avoiding the problem of the second handle 201 being damaged by pressure.

[0105] Based on the above embodiments, as a further defined implementation method, combined with... Figure 14 The gap between the lower foam part 7 and the left side or the right side of the second handle 201 is w3, 10mm≤w3≤20mm; and / or the gap between the lower foam part 7 and the bottom of the second handle 201 is w4, 15mm≤w4≤25mm.

[0106] In the above embodiments, if the gap between the lower foam component 7 and the left side or the right side of the second handle 201 is less than 10mm, after the side of the packaging structure is impacted, the lower foam component 7 will deform slightly under pressure and easily come into contact with the left or right side of the second handle 201, which may cause stress concentration at the root of the second handle 201 and result in root cracking or even breakage. If the gap between the lower foam component 7 and the left side or the right side of the second handle 201 is greater than 20mm, the lower foam component 7 will leave a larger cavity on the left and right sides of the second handle 201, resulting in an excessively large size of the packaging structure in the left and right directions, thereby increasing the volume of the outer packaging and increasing warehousing and logistics transportation costs. Therefore, by limiting the size to 10mm≤w3≤20mm, sufficient buffer space can be reserved between the side of the second handle 201 and the lower foam component 7. When the side of the packaging structure is impacted, the lower foam component 7 will not come into contact with the side of the second handle 201 after being compressed and undergoing slight deformation. This avoids stress concentration at the root of the second handle 201, which could lead to root cracking or even breakage. Furthermore, it avoids the lower foam component 7 being too large in the left and right directions, thus preventing additional increases in logistics costs.

[0107] If the gap between the lower foam component 7 and the bottom of the second handle 201 is less than 15mm, after the packaging structure is subjected to a drop impact, the lower foam component 7 will deform slightly upwards and easily come into contact with the bottom of the second handle 201, which may lead to stress concentration at the root of the second handle 201 and cause root cracking or even breakage. If the gap between the lower foam component 7 and the bottom of the second handle 201 is greater than 25mm, the lower foam component 7 needs to make a larger cavity below the second handle 201, resulting in an excessively large dimension of the packaging structure in the height direction, thereby increasing the outer packaging volume and increasing warehousing and logistics transportation costs. Therefore, limiting the gap to 15mm≤w4≤25mm allows sufficient buffer space to be reserved between the bottom of the second handle 201 and the lower foam component 7. When the packaging structure is subjected to a drop impact, the lower foam component 7 will deform slightly upwards and will not come into contact with the bottom of the second handle 201, avoiding stress concentration at the root of the second handle 201 and causing root cracking or even breakage. It also avoids the lower foam component 7 being too large in the height direction, thus avoiding additional logistics cost increases.

[0108] Based on the above embodiments, as a further defined implementation, the lower foam component 7 is provided with handle positions 702 on both sides; and / or, the lower foam component 7 is provided with a second wire passage groove 703 on one side, the second wire passage groove 703 being opposite to the first wire passage groove 606.

[0109] In the above embodiment, by providing handle positions 702 on both sides of the lower foam part 7, the user can easily remove the entire machine. By providing a second wire channel 703 on one side of the lower foam part 7, which is opposite to the first wire channel 606, the power cord 10 can be smoothly connected from the second wire channel 703 to the first wire channel 606 on the upper foam part 6.

[0110] Based on the above embodiments, as a further defined implementation, the water purifier packaging structure also includes a base tray 8, which is located at the bottom of the packaging box 9 and is used to support the lower foam component 7. The lower foam component 7 and the base tray 8 are positioned by a positioning structure.

[0111] In the above embodiment, by providing a base support 8, the lower foam component 7 can be prevented from directly contacting the bottom surface of the packaging box 9, thus avoiding the lower foam component 7 being easily affected by drops. The lower foam component 7 and the base support 8 are positioned by a positioning structure, ensuring a stable connection between them.

[0112] Specifically, the positioning structure may include a positioning groove and a positioning block. The positioning groove is located on the base 8, and the positioning block is located on the lower foam part 7. The positioning block is inserted into the positioning groove.

[0113] In this embodiment, the packaging structure for the water purifier is as follows: First, the lower foam piece 7 is installed on the base tray 8. The water purifier is then placed stably inside the lower foam piece 7, ensuring that the pure water pitcher 2 is limited by the second support rib 701, and that the second handle 201 is not gapped between it and the lower foam piece 7. The power cord 10 is then arranged, passed through the second cable groove 703 of the lower foam piece 7, and introduced into the plug limiting groove 605 of the upper foam piece 6, ensuring that the plug is locked. The upper foam piece 6 is then aligned with the top of the water purifier and vertically fitted downwards. The original water tank 3 is clamped by the limiting rib 603. The front center, two sides, and top of the glass panel 4 are all secured. The upper foam part 6 is not exposed to the surface. The front sides and top frame of the glass panel 4 are in close contact with the support strip 601. The first handle 501 of the ice storage compartment 5 is held by two first support ribs 602 on both sides. The front of the first handle 501 is not exposed to the upper foam part 6. The accessories are placed in the accessory storage slot 607. Finally, the packaging box 9 is put on from top to bottom to complete the overall packaging. This achieves effective limiting of each moving part of the water purifier and targeted protection of vulnerable parts, significantly improving transportation safety. At the same time, it avoids the cumbersome process of traditional tape fixing, and has good practicality and promotion value.

[0114] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by this application.
