Description

Technical Field

[0001] The present invention relates to a 3D printing wire drying oven, and more particularly to a 3D printing wire drying oven that can be used in conjunction with a 3D printer for fused deposition modeling (FDM) or fused filament fabrication (FFF) and a standard supplementary wire roll. Background Art

[0002] FDM or FFF 3D printers are devices that use additive manufacturing technology to quickly complete prototype production. They can create three-dimensional objects by stacking a new layer of material on top of the previous layer. The materials used to make objects can be selected from PLA, PETG, ABS, PC, nylon, etc., which are wound on open spools in the form of wires. However, due to its material properties, wires easily absorb moisture from the air, and moisture in the wires may cause printing failures. For example, when moisture vaporizes due to high temperature during the process, unexpected holes may appear on the surface of the object. Therefore, it is very important to prevent the wire from getting wet, and the market demand for closed drying ovens is also increasing.

[0003] Furthermore, the wire is currently wound on disposable plastic spools, and when the wire is used up, the spools are not recycled, so there is a problem of resource waste. In addition, different wire manufacturers use different spool specifications to wind the wire, and there is no universal and reusable spool on the market to replace the disposable spool. Summary of the invention

[0004] The main purpose of the present invention is to provide a 3D printing wire drying box that can be used with an FDM or FFF 3D printer and a supplementary wire roll that meets the standard size to solve the above-mentioned problems.

[0005] In order to achieve the above-mentioned purpose, the present invention provides a 3D printing wire drying box, which includes a shell, at least one clamping member, a lining member and a dehumidification device.

The first locking piece and the second locking piece are located between the at least one first boss structure and the at least one second boss structure and respectively abut against the at least one first boss structure and the at least one second boss structure along the first direction to prevent the supplementary wire roll or the liner from being overly compressed by the first shell portion or the second shell portion.

[0006] According to one embodiment of the present invention, the suspension structure includes an upper guide portion, and the upper guide portion is used to cooperate with an upper arc portion of the bushing member to guide a movement of the bushing member.

[0007] According to one embodiment of the present invention, the first shell further includes a first support structure, the first support structure protrudes from the first shell and is located between the first inner joint structure and the first outer joint structure; the second shell further includes a second support structure, the second support structure protrudes from the second shell and is located between the second inner joint structure and the second outer joint structure. The first support structure and the second support structure together form a guide structure, which is used to cooperate with a lower arc portion of the bushing to guide a movement of the bushing.

[0008] According to one embodiment of the present invention, when the first shell portion is combined with the second shell portion, the first supporting structure is not completely attached to the second supporting structure.

[0009] According to one embodiment of the present invention, the at least one first boss structure is located at an inner edge of the first support structure, the at least one second boss structure is located at an inner edge of the second support structure, and the dehumidification device is located between the first shell and the second shell.

[0010] According to one embodiment of the present invention, the 3D printing wire drying box further includes at least one bearing component, which is rotatably disposed on the shell component and is used to rotatably support an upper arc portion of the liner component, and a cross-section of the at least one bearing component is an inscribed circle of a cross-section of the liner component.

[0011] According to one embodiment of the present invention, the 3D printing wire drying box further includes at least one sealing component, and the at least one sealing component is disposed between the first shell portion and the second shell portion.

[0012] According to one embodiment of the present invention, the 3D printing wire drying box further includes at least one release film, which is disposed on at least one inner wall of the shell and is used to reduce a friction force acting on the supplementary wire roll and / or the liner.

[0013] According to one embodiment of the present invention, the first box portion further includes at least one first slot structure, which is located near the at least one first perforated structure and is used to accommodate the at least one first boss structure and the first locking piece. The second box portion further includes at least one second slot structure, which is located near the at least one second perforated structure and is used to accommodate the at least one second boss structure and the second locking piece. The at least one first boss structure, the at least one first perforated structure, the at least one first slot structure, the first locking piece, the at least one second boss structure, the at least one second perforated structure, the at least one second slot structure and the second locking piece are coaxially arranged.

[0015] In summary, the 3D printing wire drying box of the present invention can isolate the supplementary wire roll from the external environment and remove moisture in the internal environment of the shell through a dehumidification device when all wire outlets are not open to the external environment. Therefore, the 3D printing wire drying box of the present invention can effectively prevent the supplementary wire roll in the shell from getting damp. In addition, the 3D printing wire drying box of the present invention can be selectively placed on a horizontal support surface, hung on a bracket, or installed on a vertical wall according to actual needs. Moreover, when the shell is hung on the bracket, the central axis of the suspension structure deviates from the structural configuration set above the central axis of the liner set, which can prevent the shell from being driven by the rotating supplementary wire roll and swinging excessively during the pulling process through gravity.

[0016] Furthermore, when the supplementary wire roll in the shell is used up, the user can easily complete the replenishment of the supplementary wire roll by separating and combining the first shell and the second shell. Therefore, the 3D printing wire drying box of the present invention can replace the existing disposable spools and has the advantages of energy saving and environmental protection.

[0017] In addition, the 3D printing wire drying box of the present invention can prevent the supplementary wire roll or the liner kit from being excessively compressed by the first shell part or the second shell part by the abutment between the first boss structure and the first locking piece and the abutment between the second boss structure and the second locking piece. Therefore, the 3D printing wire drying box of the present invention can not only ensure that the supplementary wire roll and / or the liner kit can rotate freely, but also avoid wear caused by excessive friction between any one of the supplementary wire roll and the liner kit and any one of the first shell part and the second shell part.

DETAILED DESCRIPTION

[0036] The directional terms mentioned in the following embodiments, such as up, down, left, right, front or back, etc., are only used to refer to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and not to limit the present invention.

[0037] like Figures 1 to 6As shown, in the first embodiment, a 3D printing wire drying box 1 includes a shell 11, a dehumidification device 12 and a lining member 13. The shell 11 includes a hanging structure 111, a standing structure 112 and a wall-mounted structure 113. The hanging structure 111 can be provided for a bracket (not shown in the figure) to hang the shell 11, thereby allowing the 3D printing wire drying box 1 to be hung on the bracket; the standing structure 112 can support the shell 11 on a horizontal support surface (such as a desktop or the ground, not shown in the figure), thereby allowing the 3D printing wire drying box 1 to be placed near the 3D printer; the wall-mounted structure 113 can be attached to a wall-mounted member (not shown in the figure) on a vertical wall, thereby allowing the 3D printing wire drying box 1 to be installed on a vertical wall. The dehumidification device 12 is disposed in the shell 11. In this embodiment, the dehumidification device 12 can be a desiccant dehumidifier or a thermoelectric dehumidifier located in the lining member 13. The liner 13 is rotatably disposed in the shell 11 and allows a supplementary wire roll (not shown in the figure) to be disposed thereon. The shell 11 can isolate the supplementary wire roll from the external environment when all wire outlets are not open to the external environment of the shell 11, and the dehumidification device 12 can remove moisture from the internal environment of the shell 11. Therefore, the 3D printing wire drying box of the present invention can effectively prevent the supplementary wire roll in the shell 11 from getting wet. Furthermore, the central axis of the suspension structure 111 is offset and disposed above the central axis of the liner 13. When the shell 11 is suspended on the bracket, this arrangement can prevent the shell 11 from swinging excessively due to the rotating supplementary wire roll during the pulling process through gravity.

[0038] In this embodiment, the supplementary wire coil may not have any disposable spool, and the outer diameter of the liner member 13 may be designed according to the standard of a master spool, but the present invention is not limited to this embodiment.

[0039] like Figures 4 to 6As shown, in this embodiment, in order to make the rotation of the liner member 13 relative to the shell member 11 smoother and more stable, the suspension structure 111 may include an upper guide portion 1111, which can cooperate with an upper arc portion 131 of the liner member 13 to guide the rotation of the liner member 13. Furthermore, the 3D printing wire drying box 1 also includes four bearing members 14, which are rotatably disposed in the shell member 11 and rotatably support the upper arc portion 131 of the liner member 13. Two of the four bearing members 14 are disposed on the right side of the upper arc portion 131 of the liner member 13 and are separated from each other; the other two of the four bearing members 14 are disposed on the left side of the upper arc portion 131 of the liner member 13 and are separated from each other. The cross-section of the liner member 13 is circular, and the cross-section of each bearing member 14 can be an inscribed circle of the cross-section of the liner member 13. In addition, the shell 11 further includes a guide structure 114, which includes a lower guide portion 1141. The lower guide portion 1141 can cooperate with a lower arc portion 132 of the liner assembly 13 to guide the rotation of the liner assembly 13. The upper guide portion 1111 and the lower guide portion 1141 can be two arc-shaped structures. However, the present invention is not limited to this embodiment. For example, the 3D printing wire drying box may only include a bearing member that rotatably supports the lower arc portion of the liner assembly, and the cross-section of the bearing member is the circumscribed circle of the cross-section of the liner assembly. Alternatively, the upper guide portion or the lower guide portion may be a structure of other shapes. Alternatively, the upper guide portion, the lower guide portion and / or the bearing member may be selectively omitted.

[0040] like Figures 4 to 6 As shown, the guide structure 114 can be used to stop the dehumidification device 12 to prevent the dehumidification device 12 from moving randomly, and the lining member 13 can further include at least one opening structure 133, which can help the air circulation in the inner space of the shell 11. However, the present invention is not limited to this embodiment. For example, the dehumidification device can be located at the upper part or the lower part of the shell and outside the guide structure, and the lining member can have no opening structure or can have at least one notch structure to replace the opening structure.

[0041] like Figures 1 to 8As shown, the shell 11 further includes a first shell 115 and a second shell 116, and the first shell 115 and the second shell 116 are detachably connected to each other. The first shell 115 includes a first shell body 1151, a first inner combination structure 1152, a first outer combination structure 1153 and a first support structure 1154. The first inner combination structure 1152 and the first outer combination structure 1153 are respectively protruded from the inner circumference and the outer circumference of the first shell body 1151. Two first positioning structures 1155 are formed on the first shell body 1151 and are located on both sides of the first inner combination structure 1152 to install the corresponding two bearing members 14. The first support structure 1154 protrudes from the first shell body 1151 and is located between the first inner combination structure 1152 and the first outer combination structure 1153. The second shell 116 includes a second shell body 1161, a second inner combination structure 1162, a second outer combination structure 1163 and a second support structure 1164. The second inner coupling structure 1162 and the second outer coupling structure 1163 are respectively protruded from the inner circumference and the outer circumference of the second shell 1161. Two second positioning structures 1165 are formed in the second shell 1161 and are located on both sides of the second inner coupling structure 1162 to install the corresponding other two bearing members 14. The second supporting structure 1164 protrudes from the second shell 1161 and is located between the second inner coupling structure 1162 and the second outer coupling structure 1163. When the first shell 115 is combined with the second shell 116, the first inner coupling structure 1152 and the first outer coupling structure 1153 can be directly or indirectly combined with the second inner coupling structure 1162 and the second outer coupling structure 1163 in a sealed manner; and when the first shell 115 is combined with the second shell 116, the first supporting structure 1154 and the second supporting structure 1164 are not completely attached to each other, so as to facilitate the air circulation in the internal space of the shell 11, thereby ensuring that the dehumidification device 12 can function normally. The first inner joint structure 1152 and the second inner joint structure 1162 can jointly form a suspension structure 111, and the first support structure 1154 and the second support structure 1164 can jointly form a guide structure 114, that is, the first support structure 1154 and the second support structure 1164 can be respectively located on the right and left sides of the dehumidification device 12, and the outer side of the first support structure 1154 close to the liner 13 and the outer side of the second support structure 1164 close to the liner 13 can jointly form a lower guide portion 1141. However, the present invention is not limited to this embodiment, for example, at least a portion of the first support structure can be attached to at least a portion of the second support structure.

[0042] In this embodiment, the first shell 115 and the second shell 116 may be made of transparent material to facilitate observation of the remaining amount of the replenishment wire coil. However, the present invention is not limited to this embodiment. For example, the first shell or the second shell may be provided with a perspective window.

[0043] Furthermore, if Figures 3 to 6 As shown, the 3D printing wire drying box 1 further includes a sealing component 15, which is arranged between the first shell 115 and the second shell 116 and can prevent air convection between the internal environment of the shell 11 and the external environment, thereby preventing moisture from entering the internal environment. The sealing component 15 includes an inner seal 151 and an outer seal 152. The inner seal 151 is arranged between the first inner combination structure 1152 and the second inner combination structure 1162; the outer seal 152 is arranged between the first outer combination structure 1153 and the second outer combination structure 1163. However, the present invention is not limited to this embodiment. For example, the inner seal and / or the outer seal can be selectively omitted, and the corresponding two combination structures can directly abut each other.

[0044] In addition, if Figures 1 to 6 As shown, the shell 11 further includes three wire outlets 117 located in different directions to allow the wire of the supplementary wire coil to be selectively pulled out from different wire outlets 117 according to different requirements of the 3D printer; the outer seal 152 includes three through-hole structures 1521, which are respectively arranged in the three wire outlets 117 and allow the wire of the supplementary wire coil to pass through. The 3D printing wire drying box 1 also includes three inserts 16, which are respectively arranged in the three through-hole structures 1521 and can reduce the friction acting on the pulled wire. The three inserts 16 can have different inner diameters to match wires with different outer diameters. However, the present invention is not limited to this embodiment. For example, the shell and the outer seal can have only one wire outlet and one through-hole structure respectively, and the insert can be omitted. Moreover, in this embodiment, the outer seal can be a single-piece structure. However, the present invention is not limited to this embodiment. For example, the outer seal may include a plurality of sealing segments separated from each other (the through-hole structure and the insert may be omitted), and the wire may be pulled out through the gap between two corresponding sealing segments and the corresponding wire outlet.

[0045] In addition, if Figures 1 to 6 As shown, the 3D printing wire drying box 1 further includes five engaging members 17 , which can tightly combine the first shell 115 and the second shell 116 with each other.

[0046] like Figures 1 to 6 as well as Fig. 9 and Fig.10As shown, five engaging members 17 can engage the first outer coupling structure 1153 and the second outer coupling structure 1163, the engaging surface of the first inner coupling structure 1152 is more protruding than the engaging surface of the first outer coupling surface 1153, and the engaging surface of the second inner coupling structure 1162 is more protruding than the engaging surface of the second outer coupling surface 1163. This arrangement allows the first shell 115 and the second shell 116 to be tightly coupled to each other only through the engaging members 17, without the need to provide additional engaging members for engaging the first inner coupling structure 1152 and the second inner coupling structure 1162. Each engaging member 17 can be a tenon, and the first shell 115 and the second shell 116 can be elastically deformed under the action of the engaging members 17 to drive the first inner coupling structure 1152 and the second inner coupling structure 1162 to be tightly coupled to each other, and by removing the engaging members 17, the first shell 115 and the second shell 116 can be separated from each other to allow the replenishment of the wire coil. However, the present invention is not limited to this embodiment. For example, the 3D printing wire drying box may only include one clamping member for clamping the first outer binding structure and the second outer binding structure or clamping the first inner binding structure and the second inner binding structure. Alternatively, the 3D printing wire drying box may include a plurality of clamping members for clamping the first outer binding structure and the second outer binding structure and for clamping the first inner binding structure and the second inner binding structure. Alternatively, the clamping member may be omitted, and the first shell and the second shell may use other fasteners (such as screws) to ensure that they can be firmly combined with each other and will not separate from each other.

[0047] like Fig. 9 and Fig.10 As shown, the protruding length of the first inner combining structure 1152 and the protruding length of the second inner combining structure 1162 can be equal to the protruding length of the first outer combining structure 1153 and the protruding length of the second outer combining structure 1163 respectively; the first shell 1151 and the second shell 1161 can be arranged to be inclined inward, so that the combining surface of the first inner combining structure 1152 and the combining surface of the second inner combining structure 1162 can be more protruding than the combining surface of the first outer combining structure 1153 and the combining surface of the second outer combining structure 1163 respectively, so that when the first outer combining structure 1153 and the second outer combining structure 1163 are combined with each other through the snap-fitting part 17, the first shell 1151 and the second shell 1161 can respectively produce elastic deformation along two opposite arrow directions D1 and D2.

[0048] like Figure 5 and Figure 6As shown, the 3D printing wire drying box 1 further includes two release films 18, which are arranged on the inner wall of the first shell 1151 and the inner wall of the second shell 1161 and are opposite to each other; the two release films 18 can prevent the supplementary wire roll and / or the liner kit 13 from directly contacting the first shell 1151 and the second shell 1161, so as to reduce the friction acting on the supplementary wire roll and / or the liner kit 13, thereby making the rotation of the supplementary wire roll and / or the liner kit 13 smoother. However, the present invention is not limited to this embodiment. For example, the release film can be omitted. Each release film 18 can be a release paper made of a transparent material to facilitate observation of the remaining amount of the supplementary wire roll. Alternatively, the release film can be a PTFE film sprayed on the inner walls of the first shell and the second shell to reduce friction.

[0049] like Figures 11 to 16 As shown, in the second embodiment, a 3D printing wire drying box 1A includes a shell 11A, a dehumidification device 12A, a lining member 13A and four engaging members 17A. The shell 11A includes a first shell 115A and a second shell 116A detachably coupled to the first shell 115A; the first shell 115A and the second shell 116A can be tightly coupled to each other through four engaging members 17A. The dehumidification device 12A is disposed in the shell 11A, and the lining member 13A is rotatably disposed in the shell 11A and can allow the supplementary wire roll to be disposed thereon, thereby allowing the supplementary wire roll to rotate relative to the shell 11A. The shell 11A can isolate the supplementary wire roll from the external environment when all wire outlets are not open to the external environment, and the dehumidification device 12A can remove moisture from the internal environment of the shell 11A, so the 3D printing wire drying box 1A of the present invention can effectively prevent the supplementary wire roll in the shell 11A from getting damp.

[0050] In this embodiment, the supplementary wire coil may not have any disposable spool, and the outer diameter of the liner member 13A may be designed according to the standard of a master spool, but the present invention is not limited to this embodiment.

[0051] like Figures 14 to 20As shown, the first shell 115A includes a first shell 1151A, a first inner joint structure 1152A, a first outer joint structure 1153A and two first convex column structures 1156A. The first inner joint structure 1152A and the first outer joint structure 1153A protrude from the inner circumference and the outer circumference of the first shell 1151A respectively; the joint surface of the first inner joint structure 1152A is more protruding than the joint surface of the first outer joint structure 1153. The two first convex column structures 1156A protrude from the first shell 1151A and are located between the first inner joint structure 1152A and the first outer joint structure 1153A to abut against the dehumidification device 12A. The second shell 116A includes a second shell 1161A, a second inner joint structure 1162A, a second outer joint structure 1163A and two second convex column structures 1166A. The second inner coupling structure 1162A and the second outer coupling structure 1163A protrude from the inner circumference and the outer circumference of the second shell 1161A respectively; the coupling surface of the second inner coupling structure 1162A is more protruding than the coupling surface of the second outer coupling structure 1163A. The two second protruding column structures 1166A protrude from the second shell 1161A and are located between the second inner coupling structure 1162A and the second outer coupling structure 1163A to abut against the dehumidification device 12A.

[0052] like Figures 11 to 13 As shown, the first inner combining structure 1152A and the second inner combining structure 1162A can jointly form a suspension structure 111A to allow the bracket to be set therein to suspend the shell 11A; the central axis of the suspension structure 111A deviates from the central axis set above the bushing member 13A. When the shell 11A is suspended on the bracket, this arrangement can prevent the shell 11A from swinging excessively due to the rotating supplementary wire roll during the pulling-out process through gravity.

[0053] like Figures 11 to 14 As shown, the engaging member 17A can engage the first shell portion 115A and the second shell portion 116A, so that the first inner coupling structure 1152A and the first outer coupling structure 1153A are respectively coupled to the second inner coupling structure 1162A and the second outer coupling structure 1163A in a sealed manner. When the engaging member 17A engages the first shell portion 115A and the second shell portion 116A, the first shell portion 115A and the second shell portion 116A can be elastically deformed.

[0054] like Fig.19 and Fig. 20As shown, the protruding length of the first inner combining structure 1152A and the protruding length of the second inner combining structure 1162A may be respectively equal to the protruding length of the first outer combining structure 1153A and the protruding length of the second outer combining structure 1163A; the first shell 1151A and the second shell 1161A may be arranged to be inclined inwardly, so that the combining surface of the first inner combining structure 1152A and the combining surface of the second inner combining structure 1162A may be more protruding than the combining surface of the first outer combining structure 1153A and the combining surface of the second outer combining structure 1163A, so that when the first outer combining structure 1153A and the second outer combining structure 1163A are combined with each other through the snap-fitting part 17A, the first shell 1151A and the second shell 1161A may respectively produce elastic deformation along two opposite arrow directions D1A and D2A.

[0055] Furthermore, if Fig.11 and Fig.12 As shown, in this embodiment, the engaging member 17A located at the bottom may include a stand to support the shell 11A on a horizontal support surface (such as a desktop or the ground, not shown in the figure), thereby allowing the 3D printing wire drying box 1A to be placed near the 3D printer.

[0056] In another embodiment, one of the engaging members may include a wall-mounted clip, which can be attached to a wall-mounted member (not shown in the figure) on a vertical wall, thereby allowing the 3D printing wire drying box to be installed on a vertical wall.

[0057] It is worth noting that the number of the engaging parts is not limited to this embodiment. For example, the 3D printing wire drying box may only use one engaging part.

[0058] like Figures 13 to 18 and Figure 21 to Figure 22As shown, the dehumidification device 12A includes a housing box 121A to accommodate a replaceable desiccant. The housing box 121A includes a first box portion 1211A, a second box portion 1212A, and two locking components 1213A. The first box portion 1211A includes a first box body 12111A and two first perforated structures 12112A, and the two first perforated structures 12112A are formed on the first box body 12111A; the second box portion 1212A includes a second box body 12121A and two second perforated structures 12122A, and the two second perforated structures 12122A are formed on the second box body 12121A. Each locking component 1213A includes a first locking member 12131A and a second locking member 12132A. The second locking member 12132A can be locked with the first locking member 12131A. The first locking member 12131A is penetrated through the corresponding first perforated structure 12112A and the corresponding second perforated structure 12122A along a first direction parallel to the arrow directions D1A and D2A and is locked with the second locking member 12132A, thereby combining the first box portion 1211A and the second box portion 1212A with each other. The first locking member 12131A and the second locking member 12132A are located between the corresponding first boss structure 1156A and the corresponding second boss structure 1166A and respectively abut against the corresponding first boss structure 1156A and the corresponding second boss structure 1166A along the first direction to prevent the supplementary wire roll or the liner kit 13A from being excessively compressed by the first shell 115A or the second shell 116A, thereby preventing excessive friction between one of the supplementary wire roll and the liner kit 13A and one of the first shell 115A and the second shell 116A, thereby ensuring that the supplementary wire roll and / or the liner kit 13A can rotate freely and preventing the supplementary wire roll and / or the liner kit 13A from being worn.

[0059] In this embodiment, the first fastening member 12131A may be a bolt, and the second fastening member 12132A may be a nut for locking with the bolt, but the present invention is not limited to this embodiment.

[0060] like Fig.14 As shown, when the first locking piece 12131A is penetrated through the corresponding first perforated structure 12112A and the corresponding second perforated structure 12122A along the first direction and is locked with the second locking piece 12132A, so that the first box portion 1211A and the second box portion 1212A are combined with each other, the locking component 1213A has a locking length, and the sum of the protruding length of the first boss structure 1156A, the protruding length of the second boss structure 1166A and the locking length of the locking component 1213A is equal to the sum of the protruding length of the first inner combining structure 1152A and the protruding length of the second inner combining structure 1162A.

[0061] In addition, if Figures 14 to 16 and Figure 21 to Figure 22 As shown, the first box portion 1211A further includes two first slotted structures 12113A, which are respectively located near the two first perforated structures 12112A and are used to accommodate the two first boss structures 1156A and the two first fastening members 12131A to position the two first boss structures 1156A and the two first fastening members 12131A; the second box portion 1212A further includes two second slotted structures 12123A, which are respectively located near the two second perforated structures 12122A and are used to accommodate the two second boss structures 1166A and the two second fastening members 12132A to position the two second boss structures 1166A and the two second fastening members 12132A.

[0062] like Figures 14 to 16 As shown, in order to make the overall structure more reasonable and simple, the first boss structure 1156A, the first perforated structure 12112A, the first slotted structure 12113A, the first locking piece 12131A, the second boss structure 1166A, the second perforated structure 12122A, the second slotted structure 12123A and the second locking piece 12132A can be coaxially arranged.

[0063] However, the number of the locking component, the first boss structure, the second boss structure, the first perforated structure, the second perforated structure, the first slotted structure, and the second slotted structure of the present invention is not limited to this embodiment. For example, the 3D printing wire drying box may only include a locking component, a first boss structure, a second boss structure, a first perforated structure, a second perforated structure, a first slotted structure, and a second slotted structure.

[0064] like Figures 13 to 15 and Figure 17 to Figure 18As shown, in order to make the rotation of the liner 13A relative to the shell 11A smoother and more stable, the suspension structure 111A may include an upper guide portion 1111A, which can cooperate with an upper arc portion 131A of the liner 13A to guide the rotation of the liner 13A. Furthermore, the 3D printing wire drying box 1A also includes four bearing members 14A, which are rotatably disposed in the shell 11A and rotatably support the upper arc portion 131A of the liner 13A. Two of the four bearing members 14A are disposed on the first side (e.g., the right side) of the upper arc portion 131A of the liner 13A and are separated from each other; the other two of the four bearing members 14A are disposed on the second side (e.g., the left side) of the upper arc portion 131A of the liner 13A and are separated from each other. The cross-section of the liner 13A is circular, and the cross-section of each bearing member 14A may be an inscribed circle of the cross-section of the liner 13A. In addition, the shell 11A further includes a guide structure 114A, which includes a lower guide portion 1141A, and the lower guide portion 1141A can cooperate with a lower arc portion 132A of the liner 13A to guide the rotation of the liner 13A. The upper guide portion 1111A and the lower guide portion 1141A can be two arc-shaped structures. However, the present invention is not limited to this embodiment. For example, the 3D printing wire drying box may only include a bearing member that rotatably supports the lower arc portion of the liner, and the cross-section of the bearing member is the circumscribed circle of the cross-section of the liner. Alternatively, the upper guide portion or the lower guide portion may be a structure of other shapes. Alternatively, the upper guide portion, the lower guide portion and / or the bearing member may be selectively omitted.

[0065] like Figures 13 to 20As shown, the first shell 115A further includes a first supporting structure 1154A and two first positioning structures 1155A. The two first positioning structures 1155A are formed in the first shell 1151A and are located on both sides of the first inner coupling structure 1152A to install the corresponding two bearing members 14A. The first supporting structure 1154A protrudes from the first shell 1151A and is located between the first inner coupling structure 1152A and the first outer coupling structure 1153A. The first boss structure 1156A can be located at the inner edge of the first supporting structure 1154A. The second shell 116A further includes a second supporting structure 1164A and two second positioning structures 1165A. The two second positioning structures 1165A are formed in the second shell 1161A and are located on both sides of the second inner coupling structure 1162A to install the corresponding other two bearing members 14A. The second support structure 1164A protrudes from the second shell 1161A and is located between the second inner coupling structure 1162A and the second outer coupling structure 1163A. The second convex column structure 1166A may be located at the inner edge of the second support structure 1164A. When the first shell 115A is combined with the second shell 116A, the first inner coupling structure 1152A and the first outer coupling structure 1153A are directly or indirectly combined with the second inner coupling structure 1162A and the second outer coupling structure 1163A in a sealed manner respectively; and when the first shell 115A is combined with the second shell 116A, the first support structure 1154A and the second support structure 1164A are not completely fitted to each other, so as to facilitate air circulation in the internal space of the shell 11A, thereby ensuring that the dehumidification device 12A can function normally. The first support structure 1154A and the second support structure 1164A may jointly form the guide structure 114A, that is, the first support structure 1154A and the second support structure 1164A may be respectively located at the first side (e.g., the right side) and the second side (e.g., the left side) of the dehumidification device 12A, and the outer side of the first support structure 1154A close to the liner 13A and the outer side of the second support structure 1164A close to the liner 13A may jointly form the lower guide portion 1141. However, the present invention is not limited to this embodiment, for example, at least a portion of the first support structure may be attached to at least a portion of the second support structure.

[0066] In this embodiment, the first shell 115A and the second shell 116A may be made of transparent material to facilitate observation of the remaining amount of the replenishment wire coil. However, the present invention is not limited to this embodiment. For example, the first shell or the second shell may be provided with a perspective window.

[0067] It is worth noting that in this embodiment, each of the first convex column structures 1156A, each of the second convex column structures 1166A, each of the first positioning structures 1155A, and each of the second positioning structures 1165A respectively includes a recess D with an opening facing outward. The recess D not only allows the extension leg of the engaging member 17A to be inserted therein to ensure a reasonable and simple structure, but also prevents the first shell portion 115A and the second shell portion 116A from being deformed due to excessive and uneven shrinkage of the plastic injection material.

[0068] In addition, if Figure 15 to Figure 16 As shown, the liner 13A may further include at least one notch structure 133A to facilitate air circulation in the inner space of the shell 11A. However, the present invention is not limited to this embodiment. For example, the liner may not have any notch structure, or may have at least one opening structure, at least one hole structure, or at least one long groove structure to replace the notch structure.

[0069] like Figure 15 to Figure 16 and Figures 19 to 20 As shown, the 3D printing wire drying box 1A further includes a sealing component 15A, which is disposed between the first shell 115A and the second shell 116A and can prevent air convection between the internal environment of the shell 11A and the external environment when all wire outlets are not open to the external environment, thereby preventing moisture from entering the internal environment. In this embodiment, the sealing component 15A includes an outer seal 152A, which is disposed between the first outer joint structure 1153A and the second outer joint structure 1163A; the outer seal 152A can be disposed between the groove structure of the second outer joint structure 1163A and the plane structure of the first outer joint structure 1153A. However, the present invention is not limited to this embodiment. For example, the 3D printing wire drying box may include at least one of an inner seal and an outer seal, or may not include any seal.

[0070] In addition, if Figures 11 to 16 As shown, the shell 11A further includes three wire outlets 117A located in different directions to allow the supplementary wire roll to be selectively pulled out from different wire outlets 117A according to the different needs of the 3D printer. In this embodiment, the outer seal 152A includes three sealing sections, which are separated from each other to allow the supplementary wire roll to pass through the gap between the corresponding two sealing sections and the corresponding wire outlet 117A. Furthermore, the 3D printing wire drying box 1 may further include three connectors (not shown in the figure) with inserts or caps, which can be respectively arranged at the three wire outlets 117A to ensure that they are not open to the external environment, wherein the inserts can have different inner diameters to match wires with different outer diameters.

[0071] However, the present invention is not limited to this embodiment. For example, the outer seal may be similar to the first embodiment. Figure 5 and Figure 6 The single-piece structure shown has three through-hole structures, which are respectively arranged at the three wire outlets and allow the supplementary wire roll to pass through. The 3D printing wire drying box may include three inserts respectively arranged in the three through-hole structures. Alternatively, the outer seal may be a single-piece structure with the head and tail ends separated from each other to allow the supplementary wire roll to pass through the gap between the head and tail ends of the outer seal.

[0072] like Fig.15 and Fig.16 As shown, the 3D printing wire drying box 1 further includes two release films 18A, which are arranged on the inner wall of the first shell 1151A and the inner wall of the second shell 1161A and are opposite to each other; the two release films 18A can prevent the supplementary wire roll and / or the liner kit 13A from directly contacting the first shell 1151A and the second shell 1161A, so as to reduce the friction acting on the supplementary wire roll and / or the liner kit 13A, thereby making the rotation of the supplementary wire roll and / or the liner kit 13A smoother. However, the present invention is not limited to this embodiment. For example, the release film can be omitted. Each release film 18A can be a release paper made of a transparent material to facilitate observation of the remaining amount of the supplementary wire roll. Alternatively, the release film can be a PTFE film sprayed on the inner walls of the first shell and the second shell to reduce friction.

[0073] Compared with the prior art, the 3D printing wire drying box of the present invention can isolate the supplementary wire coil from the external environment and remove moisture in the internal environment of the shell through a dehumidification device when all wire outlets are not open to the external environment. Therefore, the 3D printing wire drying box of the present invention can effectively prevent the supplementary wire coil in the shell from getting damp. In addition, the 3D printing wire drying box of the present invention can be selectively placed on a horizontal support surface, hung on a bracket, or installed on a vertical wall according to actual needs. Moreover, when the shell is hung on the bracket, the central axis of the suspension structure deviates from the structural configuration set above the central axis of the liner assembly, which can prevent the shell from being driven by the rotating supplementary wire coil and swinging excessively during the pulling process through gravity.

[0074] Furthermore, when the supplementary wire roll in the shell is used up, the user can easily complete the replenishment of the supplementary wire roll by separating and combining the first shell and the second shell. Therefore, the 3D printing wire drying box of the present invention can replace the existing disposable spools and has the advantages of energy saving and environmental protection.

[0075] In addition, the 3D printing wire drying box of the present invention can prevent the supplementary wire roll or the liner kit from being excessively compressed by the first shell part or the second shell part by the abutment between the first boss structure and the first locking piece and the abutment between the second boss structure and the second locking piece. Therefore, the 3D printing wire drying box of the present invention can not only ensure that the supplementary wire roll and / or the liner kit can rotate freely, but also avoid wear caused by excessive friction between any one of the supplementary wire roll and the liner kit and any one of the first shell part and the second shell part.

[0076] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the claims of the present invention should fall within the scope of the present invention.
