Description

Technical Field

[0001] The present application relates to the field of 3D printing technology, and in particular to a storage device and a wire outlet. Background Art

[0002] 3D printing is a type of rapid prototyping technology. Wire fused deposition modeling technology is one of the mainstream technical forms in the field of 3D printing. Wire fused deposition modeling technology requires the use of 3D printing wires. 3D printing wires mainly include pure resin-based wires, short fiber-reinforced resin-based wires, and continuous fiber-reinforced resin-based wires. Since 3D printing wires usually have a certain degree of water absorption, a high water content in the wire will cause bubbles to form when the wire melts during the printing process, and may even cause the inability to print normally. Therefore, the quality of the products made by melting and printing the continuous 3D printing wire that has not been dried is poor. Therefore, maintaining a low water content in the 3D printing wire has become one of the factors that cannot be ignored in improving the quality of 3D printed products.

[0003] 3D printing filaments are usually stored in closed 3D printing filament boxes to keep the moisture content low. By setting a drying device in the box, the filaments in the box can be dried, ensuring the dryness of the filaments to a certain extent. The drying device and the filament storage box are usually an integrated design. Such a design requires each filament storage box to be equipped with a drying device, which is costly and difficult to adapt to various application scenarios. Summary of the invention

[0051] Figure 1 A modular storage device provided according to some exemplary embodiments of the present application is shown. The storage device has a modular and detachable design of a storage unit for storing a target object and a drying unit for a user to dry the target object. The modular storage device can be applied to the field of 3D printing, and can also be applied to other fields, such as industrial fields, daily necessities fields, medical fields, and agricultural fields. For example, in the field of 3D printing, the target object can be a reel of 3D printing wire or a reel of other wires. In other fields, the target object can also be any object that needs to be stored in a specific humidity environment (or dryness environment), such as raw materials, clothing, medicines, fruits and vegetables, books, etc. For the convenience of explanation, the subsequent description of the target object in this specification will take a reel wound with wire as an example.

[0052] exist Figure 1 In the embodiment, the modular storage device 10 includes a storage unit 100 (i.e., a storage bin) and a drying unit 200. During use, the storage unit 100 and the drying unit 200 are independent of each other and can be detachably assembled together. In other words, the storage unit 100 can be used as the smallest unit to store the wire reel, or it can be assembled together with another independent module drying unit 200 as an independent module, and the wire in the wire reel can be actively dried while storing the wire reel. The same drying unit 200 can be adapted to multiple storage units 100, so that the target objects in the multiple storage units 100 can be dried or moisturized. For example, in a 3D printing scenario, the target object can be 3D printing wire.

[0053] Figure 2 A schematic diagram of the internal air circulation of a modular storage device 10 provided according to some exemplary embodiments of the present application is shown. The drying unit 200 has power, and can extract the internal air in the storage unit 100 (storage bin), adjust the humidity, and then inject it into the storage unit 100. There is a humidity difference between the air outside the storage unit 100 (external air) flowing through the drying unit 200 and the internal air extracted from the storage unit 100 (storage bin), wherein the internal air extracted from the storage unit 100 has a first relative humidity, and the external air flowing through the drying unit 200 has a second relative humidity.

[0054] The storage device 10 can be used to adjust the relative humidity in the storage unit 100. When the second relative humidity is higher than the first relative humidity, the drying unit 200 can export the dry internal air in the storage unit 100 and import the humid external air; when the second relative humidity is lower than the first relative humidity, the drying unit 200 can also export the humid internal air in the storage unit 100 and import the dry external air. In the 3D printing scenario, the main function of the modular storage device 10 is to keep the 3D printing wire dry.

[0055] Figure 3 Shown in the first perspective Figure 1 The structure of the storage unit 100 in the storage device shown in FIG. Figure 4 The schematic diagram of the structure of the storage unit at the second viewing angle is shown to show different sides of the storage unit 100. The first viewing angle is opposite to the second viewing angle. The storage unit 100 may include a box body 110, a box cover 120, a color developing desiccant 130 and a hygrometer 140.

[0056] The box body 110 and the box cover 120 can be coupled together by a variety of detachable and sealed connection methods, such as threaded connection, snap connection, or hinge and snap combination connection. Through these detachable and sealed connection methods, the box cover 120 can be removed from the box body 110 to facilitate the insertion or removal of the wire reel. For example, after the box cover 120 is covered on the box body 110, it can be detachably connected to the box body 110 by snap connection. Figure 3 As shown, the box cover 120 is provided with a first clamping edge 121, the box body 110 is provided with a second clamping edge 111, and buckles 112 are provided on both sides of the box body 110. When the box cover 120 is covered on the box body 110, the first clamping edge 121 is placed on the second clamping edge 111, and the box body 110 and the box cover 120 are connected by closing the buckle 112. It should be noted that the buckle 112 can be located on the box body 110, can also be located on the box cover 120, and can also be located on both the box cover 120 and the box body 110.

[0057] In order to achieve the sealing of the storage unit 100, a sealing groove (not shown) is provided in the first clamping edge 121, and a sealing member is provided in the sealing groove. The sealing member may be a sealing ring, a sealant, a soft filler, etc. When the box body 110 and the box cover 120 are connected through the first clamping edge 121 and the second clamping edge 111, the sealing member in the sealing groove seals the gap formed by the box body 110 and the box cover 120, so as to isolate the internal space of the storage unit 100 from the external environment and prevent external impurities and moisture from invading the storage unit 100.

[0058] The box body 110 may have a variety of shapes, such as cylindrical, polygonal, etc. In each shape, the box body 110 may include one or more side walls 113. Figure 3 and Figure 4 In the embodiment, the storage unit 100 is in the shape of a hexahedron. Accordingly, the side wall 113 may include a first side wall 1131, a second side wall 1132, a third side wall 1133, a fourth side wall 1134 and a box bottom 1135. The first side wall 1131 and the second side wall 1132 are arranged opposite to each other, and the third side wall 1133 and the fourth side wall 1134 are arranged opposite to each other. It should be noted that the box body 110 may be assembled or integrally formed.

[0059] When the box cover 120 covers the box body 110, the internal space is formed. This internal space is used to store the wire reel (target object) in a closed manner to maintain the dryness of the target object for a certain period of time. It should be noted that the airtightness of the internal space is relatively closed, that is, there are tiny gaps in this internal space, and water molecules from the outside can slowly penetrate into the storage unit 100. When the content of water molecules from the outside in the internal space reaches a certain level, the drying unit 200 is required to actively dry it to maintain the dryness of the internal space. Among them, the dryness indicates the amount of moisture contained in the air in the internal space. The more moisture, the lower the dryness, and the less moisture, the higher the dryness. In other words, the dryness can indicate the dryness of the internal space, or it can indicate the humidity of the internal space.

[0060] During active drying, the storage unit 100 is placed on the carrying surface 202 of the drying unit 200. Accordingly, the box bottom 1135 may be provided with a first air outlet 150 and a first air inlet 160 to couple with the carrying surface 202 of the drying unit 200. The box body 110 may be detachably connected to the drying unit 200 via the first air outlet 150 and the first air inlet 160. Figure 5 for Figure 1 The partial enlarged view of the dotted line A portion of the storage device shown shows the structure of the detachable connection portion between the storage unit 100 and the drying unit 200. As mentioned above, the internal air in the box body 110 can be exchanged with the air in the external environment outside the box body 110 through the first air outlet 150 and the first air inlet 160, and the drying unit 200 can also heat the internal air in the internal space of the box body 110 through the first air outlet 150 and the first air inlet 160.

[0061] Specifically, the first air outlet 150 can be coupled with the second air inlet 220 on the drying unit 200, so that the drying unit 200 can export the internal air in the box body 110. At the same time, the first air inlet 160 can be coupled with the second air outlet 210 on the drying unit 200, so that the drying unit 200 can introduce external air into the internal space of the box body 110. The internal air refers to the air remaining in the internal space of the box body, and the external air refers to the air from outside the internal space of the box body.

[0062] The air inside the box body 110 can be dry air or humid air. When the air inside is dry air, the air in the external environment is relatively humid. After a long period of infiltration, the air inside changes from dry air to humid air. At this time, the user can actively dry the storage unit 100, that is, assemble the storage unit 100 and the drying unit 200 together and turn on the drying unit 200. The drying unit 200 guides the humid internal air in the box body 110 through the first air outlet 150 and the second air inlet 21 and introduces dry external air into the storage unit 100 through the second air outlet 210 and the first air inlet 160.

[0063] When the internal air is humid air and the external air is relatively dry air, after a long period of infiltration, the internal air changes from the original humid air to dry air. At this time, the user can actively moisturize the storage unit 100, that is, assemble the storage unit 100 and the drying unit 200 together and turn on the drying unit 200. The drying unit 200 guides the dry internal air in the box body 110 through the first air outlet 150, and introduces the humid external air into the storage unit 100 through the first air inlet 160.

[0064] Therefore, through the above-mentioned operation, the humidity of the air inside the storage unit 100 can be adjusted by the drying unit 200 .

[0065] It should be noted that dry air and humid air are relative concepts, that is, the air with lower humidity is dry air, and the air with higher humidity is humid air. In the 3D printing scenario, the main function of the modular storage device 10 is to keep the 3D printing wire dry.

[0066] like Figure 5As shown, in order to couple with the drying unit 200, coupling mechanisms may be respectively provided on the first air outlet 150 and the second air inlet 220. The coupling mechanism may have a variety of design schemes. For example, a first card slot 151 may be provided on the first air outlet 150 of the storage unit 100. Correspondingly, a first hook 221 may be provided on the second air inlet 220 of the drying unit 200. Coupling mechanisms may also be respectively provided on the first air inlet 160 and the second air outlet 210. The coupling mechanism may have a variety of design schemes. For example, a second card slot 161 may be provided on the first air inlet 160. Correspondingly, a second hook 211 may be provided on the second air outlet 210 of the drying unit 200. In this way, when the box body 110 and the drying unit 200 are assembled together, the box body 110 can be engaged with the first hook 221 on the drying unit 200 through the first slot 151 on the first air outlet 150, and then engaged with the second hook 211 on the drying unit 200 through the second slot 161 on the first air inlet 160, thereby realizing the coupling of the box body 110 and the drying unit 200.

[0067] In addition, in addition to the hook and slot coupling, the box body 110 and the drying unit 200 can also be coupled in other ways, such as magnet coupling, bolt coupling, etc.

[0068] When the storage unit 100 and the drying unit 200 are assembled together, the drying unit 200 can actively adjust the humidity for the box body 1. When the storage unit 100 and the drying unit 200 are separated, the storage unit 100 can maintain the dryness of the internal air in a passive mode. This requires sealing the first air outlet 150 and the first air inlet 160.

[0069] In order to seal the first air outlet 150, an air outlet cover (not shown in the figure) is provided on the first air outlet 150. The air outlet cover can be in an open state or in a closed state. When the first card slot 151 on the first air outlet 150 is engaged with the first hook 221 on the drying unit 200, the air outlet cover is opened, the first air outlet 150 is in an open state, and the internal air can flow out; when the first card slot 151 on the first air outlet 150 is disengaged from the first hook 221 on the drying unit 200, the air outlet cover is closed to seal the first air outlet 150, at which time the first air outlet 150 is in a closed state, and the outflow of the internal air is cut off. It should be noted that the air outlet cover and the first air outlet 150 can be independent of each other, for example, the box body 110 can include an independent air outlet cover; the air outlet cover and the first air outlet 150 can also be connected by a hinge and a spring mechanism, or flexibly connected by an elastomer, which is not limited here.

[0070] In order to seal the first air inlet 160, an air inlet cover (not shown in the figure) is also provided on the first air inlet 160. The air inlet cover can be in an open state or in a closed state. When the second card slot 161 on the first air inlet 160 is engaged with the second card hook 211 on the drying unit 200, the air inlet cover is opened, the first air inlet 160 is in an open state, and external air flows into the storage unit 100; when the second card slot 161 on the first air inlet 160 is disengaged from the second card hook 211 on the drying unit 200, the air inlet cover is closed to seal the first air inlet 160, at which time the first air inlet 160 is in a closed state, and the inflow of external air is cut off. It should be noted that the air inlet cover and the first air inlet 160 can be independent of each other, for example, the box body 110 can include an independent air inlet cover; the air inlet cover and the first air inlet 160 can also be connected by a hinge and a spring mechanism, or flexibly connected by an elastomer, which is not limited here.

[0071] Under normal circumstances, the target object, such as the 3D printing wire wound on the wire drum, needs to be placed in the storage unit 100. When in use, the wire drum is installed on the 3D printer together with the storage unit 100 to keep the dryness (humidity) of the wire drum at all times. This requires that the wire drum can be fixed in position and kept rotatable in the box body 110 to transport the wire to the 3D printer.

[0072] like Figure 3 As shown, the box body 110 includes, in addition to the side wall 113, a limiting mechanism 114 disposed between the first side wall 1131 and the second side wall 1132. The limiting mechanism 114 is used to limit the movement of the wire drum between the third side wall 1133 and the fourth side wall 1134 in the box body 110 and is rotatably connected to the wire drum. For example, the limiting mechanism 114 can be disposed in the middle of the internal space of the box body 110, that is, in the middle part of the first side wall 1131 and the middle part of the second side wall 1132; it can also be disposed in the lower part of the internal space of the box body 110, that is, the middle part of the first side wall 1131 and the lower part of the second side wall 1132 close to the bottom 1035; it can also be disposed in the middle and lower parts of the internal space of the box body 110 at the same time.

[0073] When the limiting mechanism 114 is disposed at the lower portion of the inner space of the box body 110, as shown in FIG. Figure 3 As shown, the limiting mechanism 114 may include N limiting rods 1141, where N is a natural number greater than or equal to 1. One end of the N limiting rods 1141 is connected to the first side wall 1131, and the other end is connected to the second side wall 1132. Figure 3In the structure shown, N=2. Each of the N limit rods 1101 is parallel to the axial direction of the wire drum, and the arrangement can be arranged along the outer edge of the wire drum. In this way, the N limit rods can support the wire drum from the bottom of the wire drum. Furthermore, each limit rod 1101 can be designed as a roller, that is, each limit rod 1101 can rotate. In this way, when the wire drum rotates, the N limit rods 1141 in contact with the outer edge of the wire drum also rotate with the wire drum, thereby preventing the wire drum from rolling due to friction between the limit rod 1101 and moving between the third side wall 1133 and the fourth side wall 1134 in the box body 110.

[0074] The N limiting rods 1141 may be fixed by a slide rail or a bracket.

[0075] When N limiting rods 1141 are fixed by slides, the first side wall 1131 and the second side wall 1132 can be respectively provided with a plurality of slides extending along the vertical direction along the corresponding side walls. Each slide and the end of its corresponding limiting rod 1101 can be coupled with each other. When a limiting rod 1141 is placed in the internal space of the box body 110, one end can slide down along the slide on the first side wall 1131, and the other end can slide down along the slide on the second side wall 1132. When the limiting rod 1101 reaches the preset working position, the limiting rod 1101 is stuck by the slide and stops sliding downward. The coupling structure of the slide and the end of the limiting rod can have various designs, and the present application does not impose specific restrictions.

[0076] In addition, the N limiting rods 1141 can also be fixed by brackets, that is, N limiting rod brackets are preset at the lower part of the box body 110, and the N limiting rods 1141 are placed on the N limiting rod brackets to fix the N limiting rods 1141.

[0077] It should be noted that the N limiting rods 1141 may be fixed by a slide, or by a bracket, or by both a slide and a bracket.

[0078] like Figure 3 As shown, when the limiting mechanism 114 is arranged in the middle of the inner space of the box body 110, the limiting mechanism 114 may include a slideway; or may include both a slideway and a wire drum shaft 1144 as a limiting rod. The wire drum shaft 1144 refers to a shaft passing through the central axis hole of the wire drum.

[0079] The slideway may include a first slideway 1142 and a second slideway 1143. The first slideway 1142 may be disposed on the first side wall 1131 and extend in the vertical direction of the box body 110; the second slideway 1143 may be disposed on the second side wall 1132 and extend in the vertical direction of the box body 110. The wire drum shaft 1144 may include a first end and a second end. The first end may be slidably coupled to the first slideway 1142; the second end may be slidably coupled to the second slideway 1143. A first stopper is disposed at the lower end of the first slideway 1142 to prevent the first end of the wire drum shaft 1144 from continuing to slide down along the first slideway 1142; a first stopper is disposed at the lower end of the second slideway 1143 to prevent the second end of the wire drum shaft 1144 from continuing to slide down along the second slideway 1143.

[0080] The coupling structure of the first slide 1142 and the second slide 1143 and the end of the corresponding wire drum shaft 1144 can have various designs, and the present application does not make specific restrictions. For example, the first slide 1142 and the second slide 1143 can be a slide groove. M long ridges and N short ridges can be arranged on the first slide 1142 and the second slide 1143, wherein M is an integer greater than or equal to 2, and N is an integer greater than or equal to 1. The M long ridges are symmetrically distributed on both sides of the N short ridges and each of the M long ridges is parallel to each of the N short ridges, so the M long ridges and the N short ridges together constitute two U-shaped grooves. Further, the M long ridges and the N short ridges on the first slide 1142 are arranged on the first side wall 1131, and the M long ridges and the N short ridges on the second slide 1143 are arranged on the second side wall 1132. The number of long ridges and the number of short ridges on the first slideway 1142 may be the same or different.

[0081] As described above, the limiting mechanism 114 may be composed of a slideway, or may be composed of a slideway and a wire drum shaft 1144. In the case where the limiting mechanism 114 is composed of a slideway and a wire drum shaft 1144, the wire drum shaft 1144 is first placed in the central axis hole of the wire drum, and then the wire drum and the wire drum shaft 1144 are placed together in the first slideway 1142 and the second slideway 1143. Further, the first end of the wire drum shaft 1144 is slidably connected to the first slideway 1142, and the second end is slidably connected to the second slideway 1143, that is, one end of the wire drum shaft 1144 is coupled in the U-shaped groove on the first slideway 1142, and the second end of the wire drum shaft 1144 is coupled in the U-shaped groove on the second slideway 1143. In the case where the limiting mechanism 114 is composed of a slideway, the wire drum can be designed to have a wire drum shaft. When the wire drum is placed in the slideway, the first end of the wire drum shaft is slidably connected to the first slideway 1142, and the second end is slidably connected to the second slideway 1143, that is, one end of the wire drum shaft 1144 is coupled in the U-shaped groove on the first slideway 1142, and the second end of the wire drum shaft 1144 is coupled in the U-shaped groove on the second slideway 1143. It can be understood that the first slideway 1142 and the second slideway 1143 can also be slide rails, that is, the wire drum is provided with corresponding sliders, and when the wire drum is placed in the first slideway 1142 and the second slideway 1143, the sliders on the wire drum slide on the slide rails.

[0082] After the wire reel is placed in the storage unit 100 and installed on the 3D printer, the wire on the wire reel enters the 3D printer nozzle through the wire feeding mechanism on the 3D printer, thereby participating in 3D printing. Therefore, the box body 110 also includes at least one wire outlet 115, and the at least one wire outlet 115 is configured so that when the wire reel participates in printing, the wire extends from the at least one wire outlet 115.

[0083] Figure 6 The structure schematic diagram of the wire outlet 115 provided according to some exemplary embodiments of the present application is shown. The at least one wire outlet 115 can be arranged on the side wall 113 of the box body 110 or on the box cover 120.

[0084] The wire outlet 115 includes a first outlet 1151 and a second outlet 1152. The first outlet 1151 is provided with a first outlet cover 1153, and the second outlet 1152 is provided on the first outlet cover 1153. The first outlet 1151 allows a first wire having a first diameter φ1 to pass through; the second outlet 1152 allows a second wire having a second diameter φ2 to pass through. The first diameter φ1 is greater than the second diameter φ1; accordingly, the diameter of the first outlet 1151 is greater than the diameter of the second outlet 1153.

[0085] At least one clamping structure is provided on the wire outlet 115, for clamping the wire extending from the at least one wire outlet 115. For example, the diameter of the first outlet 1151 may be slightly smaller than the first diameter φ1, so that when the first wire passes through the first outlet 1151, the first outlet can grip the first wire by friction; similarly, the diameter of the second outlet 1152 may be slightly smaller than the second diameter φ2, so that when the first wire passes through the first outlet 1152, the first outlet can grip the second wire by friction.

[0086] When the wire outlet 115 is made of a rigid material, the gripping force of the first outlet 1151 on the first wire comes from the tight fit between the diameter of the first outlet and the first diameter φ1; the gripping force of the second outlet 1152 on the second wire comes from the tight fit between the diameter of the second outlet and the second diameter φ2. When the first outlet 1151 and the second outlet 1152 are made of an elastic material, the clamping design (clamping structure) may include: Figure 6 The valve structure shown. That is, the first outlet 1151 may include a first wire hole and a plurality of cracks radiating outward from the inner edge of the first wire hole, thereby forming a plurality of valves. In this way, when the first wire passes through the first wire hole, the plurality of valves are slightly deformed, thereby clamping the first wire. Similarly, the second outlet 1152 may include a second wire hole and a plurality of cracks radiating outward from the inner edge of the second wire hole, thereby forming a plurality of valves.

[0087] When the first wire extends from the first outlet 1151, the first outlet cover 1153 is removed from the first outlet 1151, so that the first outlet 1151 is in an open state, allowing the first wire to extend from the first outlet 1151 and remain on the first outlet 1151. At this time, the first wire forms a seal for the first outlet 1151 at the same time.

[0088] The wire outlet 115 also allows the second wire to extend from the second outlet 1152. At this time, the first outlet cover 1153 covers the first outlet 1151, and the second wire extends from the second outlet 1152 and remains on the second outlet 1152. At this time, the second outlet cover 1153 forms a seal on the first outlet; the second wire forms a seal on the second outlet 1152. It can be understood that since the diameter of the first outlet 1151 is greater than the diameter φ2 of the second wire, when the wire reel participates in printing, the wire of the second diameter can also extend from the first outlet 1151. After printing is completed, the first outlet cover 1153 can cover the first outlet 1151 to play a sealing role.

[0089] like Figure 3As shown, the wire outlet 115 can also be designed as a third outlet 1154 for a third wire having a third diameter φ3 to extend from the storage unit 100. It should be noted that the third diameter φ3 can be greater than or equal to the first diameter φ1, or less than or equal to the second diameter φ2, or between the first diameter φ1 and the second diameter φ2. The diameter of the third outlet 1154 can be slightly smaller than the third diameter φ3, so that the third outlet can hold the third wire.

[0090] The third outlet 1154 also includes a clamping design (clamping structure). When the third outlet 1154 is made of a rigid material, the clamping force of the third outlet 1154 on the first wire comes from the tight fit between the diameter of the third outlet and the third wire. When the third outlet 1154 is made of an elastic material, its clamping structure can be designed as follows: Figure 6 The valve shape shown. Figure 6 The valve structure in has been described and will not be repeated here.

[0091] Furthermore, the third outlet 1154 is provided with a second outlet cover 1155 which can be opened and closed with the first outlet 1151. When the second outlet cover 1155 is opened, the third wire can extend from the third outlet 1154 and seal the third outlet 1154. When the second outlet cover 1155 is closed, the second outlet cover 1155 seals the third outlet 1154.

[0092] In addition, if Figure 3 As shown, the storage unit 100 also includes a desiccant bin 155, and the desiccant bin 155 is non-detachably arranged in the storage unit 100. Further, a color desiccant 130 is placed in the desiccant bin 155, and the color desiccant 130 can be reused, so it can always exist in the desiccant bin 155 without being taken out. The color desiccant 130 can absorb moisture in the internal air in the box body 110 to passively dry the box body 110, and at the same time indicate the water content of the color desiccant 130 itself by changing its own color. As the color desiccant 130 absorbs moisture in the air, its own color will change. When the color desiccant 130 in the desiccant bin 155 becomes a preset color, it means that the color desiccant 130 itself is already sufficiently moist, and the drying unit 200 needs to actively dry it. Further, when the drying unit 200 dries the air inside the box body 110, the color desiccant 130 is also dried at the same time. When the color-developing desiccant 130 changes back to its original color, it indicates that the active drying can be stopped. It should be noted that the color-developing desiccant 130 is reusable, that is, when the active drying stops, the color-developing desiccant 130 returns to its original state and color, and the color-developing desiccant 130 can continue to passively dry the air in the box body 110.

[0093] like Figure 3As shown, in addition to the desiccant bin 155, the storage unit 100 is also provided with a hygrometer bin (not shown in the figure). The hygrometer bin is used to store the hygrometer 140. Among them, the hygrometer 140 is configured to indicate the air humidity of the internal space of the box body 110. When the box body 110 gradually becomes humid, the hygrometer 140 can sensitively detect the air humidity of the internal space of the box body 110, so as to facilitate the staff to judge the humidity condition in the box body 110 and decide the time to actively dry the box body 110. Further, when the drying unit 200 dries the air inside the box body 110, the hygrometer 140 can display the dryness of the internal space of the box body 110 in real time. Therefore, the hygrometer 140 can be used to judge the humidity condition of the internal air at the current moment, and the color developing desiccant 130 can be used to judge how much passive drying capacity is left in the box body 110.

[0094] As mentioned above, the modular storage device further includes a drying unit 200. The drying unit 200 may be configured to be coupled with the storage unit 100 to dry the internal air of the storage unit 100. As mentioned above, during active drying, the drying unit 200 may be coupled with the first air inlet 160 through the second air outlet 210 to introduce external air into the internal space of the box body 110. At the same time, the drying unit 200 may be coupled with the first air outlet 150 through the second air inlet 220 to guide the internal air in the box body 110 out. The specific coupling method has been described above and will not be repeated here.

[0095] Fig. 7A According to the present application Figure 1 A perspective view of a drying unit in the storage device shown; Figure 7B According to the present application Fig. 7A The cross-sectional view of the drying unit along plane B is shown in FIG. Figure 5 , Fig. 7A and Figure 7B As shown, the drying unit 200 includes a carrying surface 202 to carry and / or place the storage unit 100. The carrying surface 202 may include a second air outlet 210 and a second air inlet 220, that is, the second air outlet 210 and the second air inlet 220 are respectively arranged on the carrying surface 202.

[0096] In addition, the drying unit 200 may further include an air driving module 230 and a drying module 240. The drying module 240 may be connected to the second air inlet 220 and the second air outlet 210 and may reduce the relative humidity of the external air flowing therethrough. The air driving module 230 may be connected to the drying module 240 and, when in operation, extract the internal air of the storage unit 100 through the second air inlet 220 and inject the external air of the storage unit 100 into the storage unit 100 through the second air outlet 210.

[0097] The drying module 240 may be a heating drying module 240 , a dehumidifying drying module 240 , or a drying module combining heating and dehumidifying types.

[0098] The heating drying module 240 may include a heating wire 242 and an air passage 241. The heating wire 242 is disposed in the air passage 241, and heats the air flowing through the air passage 241 to reduce the relative humidity of the external air flowing through the air passage. The dehumidifying drying module 240 may include a desiccant unit 242 and an air passage 241. The desiccant unit 242 includes an air desiccant and is disposed in the air passage 241, and absorbs moisture in the air to reduce the relative humidity of the external air flowing through the air.

[0099] It should be noted that reducing the relative humidity of the external air flowing through can be understood as increasing the relative dryness of the external air flowing through. Relative humidity refers to the percentage of water vapor in the air to saturated water vapor, where the saturation of water vapor in the air changes with temperature. The saturation of water vapor in hot air is high, and the saturation of water vapor in cold air is low. Therefore, when the water vapor content in the external air remains unchanged, increasing the air temperature will reduce the relative humidity, that is, increasing the air temperature will make the air drier; lowering the air temperature will increase the relative humidity, that is, lowering the air temperature will make the air humid. At this time, reducing the relative humidity of the external air can be understood as reducing the humidity of the external air, making the external air dry, or it can be understood as reducing the dryness of the external air, making the external air more humid.

[0100] The air channel 241 may be completely connected to the second air outlet 210 and the second air inlet 220. The air channel 241 may also partially connect the second air outlet 210 and the second air inlet 220, while allowing the air in the surrounding environment of the drying unit 200 to flow into the air channel 241. Accordingly, the external air flowing through the drying module 240 may come entirely from the internal air in the box body 110, or may include part of the internal air and part of the air in the surrounding environment.

[0101] The air driving module 230 can extract the internal air of the box body 110 through the second air inlet 220 and introduce it into the air passage 241, and then dry it through the drying module 240, and then inject the external air in the air passage into the box body 110 through the second air outlet 210. In the case where the air passage 241 partially connects the second air outlet 210 and the external environment of the drying unit 200, the air driving module 230 can extract the internal air of the box body 110 through the second air inlet 220 and inject the air in the external environment into the box body 110 through the second air outlet 210. In addition, the air driving module 230 can be any device that can extract and introduce air, such as a vacuum pump, an exhaust fan, a negative pressure fan, etc.

[0102] When the drying module 240 is a heating drying module 240, the drying module 240 heats the air from the internal space of the box body 110 to increase the dryness of the air, and introduces the heated air into the internal space of the box body 110 as external air. When the internal space becomes dry, the moisture in the color desiccant 130 and the water molecules attached to the wire coil and the 3D printing wire will enter the internal air and be exported by the drying module 240, thereby reducing the moisture content of the color desiccant 130, the wire coil and the 3D printing wire. It should be understood that although most of the air heated by the drying unit 200 comes from the internal air in the box body 110, a small part of the air in the surrounding environment is still allowed to mix with the exported internal air to become external air. In this way, after a certain period of iteration, all the air in the internal space before active drying is continuously replaced by dry air around the drying module 240, thereby removing the moisture in the color desiccant 130, the wire coil and the 3D printing wire.

[0103] When the drying module 240 is a dehumidifying drying module 240, the internal air in the internal space of the box body 110 is led out and flows through the drying module 240. The drying module 240 can absorb the moisture in the air flowing through it. After this part of the dried air is re-introduced into the storage unit 100, it will take out the moisture in the color developing desiccant 130, the wire reel and the 3D printing wire. This cycle continues. Of course, the drying unit 200 can also lead out the internal air in the internal space of the box body 110 and discharge it into the surrounding environment, and at the same time, introduce the external air in the surrounding environment into the internal space of the box body 110 through the drying module 240, so as to achieve the effect of reducing the relative humidity of the external air.

[0104] Figure 8 A schematic diagram of the composition of a modular storage device provided according to some exemplary embodiments of the present application is shown. The storage unit 100 can be used alone as a unit of a storage reel, or it can be assembled together as a storage module and a drying unit 200 to form a storage reel. Among them, the drying unit 200 can be adapted to multiple storage units 100, that is, multiple storage units 100 can be installed on the same drying unit 200. Therefore, this modular design of separating the storage unit 100 and the drying unit 200 can enable one drying unit 200 to dry multiple storage units 100. The number of storage units 100 and the number of drying units 200 in the modular storage unit storage device may be different. Further, the number of storage units 100 may be greater than the number of drying units 200, may be equal to the number of drying units 200, or may be less than the number of drying units 200.

[0105] Fig. 9A schematic diagram of a modular storage device provided according to some exemplary embodiments of the present application when participating in 3D printing is shown. It can be seen that when the storage unit 100 stores wire alone, it can be directly connected to a 3D printer to participate in printing. However, when the storage unit 100 and the drying unit 200 are assembled together, the wire in the storage unit 100 does not participate in this round of printing.
