Technical Field
[0001] This utility model relates to the technical field of 3D printing consumables storage boxes, and in particular to a moisture-proof storage box for 3D printing consumables. Background Technology
[0002] Thermoplastic filaments such as PLA, ABS, and PETG used in 3D printing need to be stored in a moisture-proof manner after opening to avoid performance degradation caused by moisture absorption. This can be achieved by using a storage box with a desiccant.
[0003] Different 3D printing projects use different materials of filaments. The remaining filaments need to be stored in a moisture-proof manner. The existing storage boxes are fixed-volume boxes that cannot be dynamically adjusted according to the quantity and specifications of the filaments, leading to the contradiction of "wasteful capacity" or "insufficient capacity". When multiple rolls of filaments need to be stored, multiple storage boxes need to be purchased, which not only increases the user's purchase cost (multiple boxes added together), but also occupies a lot of desktop / storage space. When there are few filaments, the stacking of empty boxes further squeezes out the idle space. Summary of the Invention
[0004] This utility model provides a moisture-proof storage box for 3D printing consumables. The upper box slides up and down along the inner wall of the lower storage box via a lower extension slide, which can adjust the height. When more 3D printing consumables need to be stored, the upper box slides away from the lower storage box, allowing a single storage box to adapt to dynamic storage needs from small to large capacity. There is no need to add extra storage boxes for different capacity needs, reducing the cost for users to purchase multiple storage boxes.
[0005] This utility model provides a moisture-proof storage box for 3D printing consumables, specifically including a lower storage box, an upper box, and an upper cover. The upper box is located above the lower storage box, and the upper cover is slidably connected to the upper part of the upper box. A lower grid plate is fixedly installed on the lower inner side of the lower storage box. A desiccant storage chamber is opened at the bottom of the lower storage box, and the desiccant storage chamber is filled with desiccant. The lower end of the desiccant storage chamber is threadedly connected to the central through column. Side cover plates are hinged and rotatably connected to both sides of the desiccant storage chamber. The side cover plates and the desiccant storage chamber are equipped with locking strips and sealing rings to improve the sealing performance. Side magnetic plates are fixedly connected to both outer sides of the lower storage box.
[0006] Furthermore, the desiccant storage chamber is located below the lower grid plate, with the central through column and the lower grid plate axially penetrating each other. The central through column is located inside the lower storage box and is set along the height direction of the lower storage box. It is used to pass through the shaft of the 3D printing consumable roll. The lower grid plate is used to connect the lower storage box and the desiccant storage chamber.
[0007] Furthermore, a lower extension slide is fixedly connected to the lower inner side of the upper housing, and an outer corrugated sealing ring is fixedly connected to the lower outer side of the upper housing.
[0008] Furthermore, the lower extension slide is located inside the outer corrugated sealing ring. The lower extension slide slides against the inner side of the lower storage box and slides up and down along the inner wall of the lower storage box to adjust the height of the upper box relative to the lower storage box. This allows a single storage box to adapt to dynamic storage needs ranging from small to large capacity, eliminating the need to add additional storage boxes for different capacity requirements. The lower end of the outer corrugated sealing ring is fixedly connected to the lower storage box, and a radial seal is formed between the upper box and the lower storage box through the outer corrugated sealing ring.
[0009] Furthermore, the lower part of the upper cover is provided with a through hole in a rectangular array, and a side sealing plate is rotatably connected to the side hinge of the upper cover. The upper cover has a desiccant receiving cavity inside, which is filled with desiccant. The axial fastening force of the upper cover and the upper box body after sliding insertion is greater than the weight of the upper box body. When the bottom of the upper cover is supported by consumables, and because the axial fastening force between the upper cover and the upper box body is greater than the weight of the upper box body itself, the two will not separate.
[0010] Furthermore, when the upper cover and the upper box body are slid in, the interior of the upper cover is connected to the interior of the upper box body through the lower through hole, and the desiccant in the upper cover cavity is connected to the interior of the upper box body through the lower through hole.
[0011] Furthermore, side magnetic plates are fixedly connected to both sides of the upper box, and the lower storage box of the adjacent storage box is magnetically attached to the upper box through the side magnetic plates.
[0012] This utility model provides a moisture-proof storage box for 3D printed consumables, which has the following beneficial effects: The lower and upper storage boxes are used to store 3D printing consumables. The upper box slides up and down along the inner wall of the lower storage box via a lower extension slide, allowing for height adjustment. When more 3D printing consumables need to be stored, the upper box slides away from the lower storage box, and the outer corrugated sealing ring elastically extends simultaneously. The outer corrugated sealing ring always maintains a sealing effect between the lower and upper storage boxes, allowing a single storage box to adapt to dynamic storage needs ranging from small to large capacity. This eliminates the need to add additional storage boxes for different capacity requirements, significantly reducing the cost for users to purchase multiple storage devices.
[0013] The lower and upper storage boxes of adjacent storage boxes are magnetically attached and spliced together by side magnetic plates to form an integrated storage unit. This prevents individual storage boxes from tipping over due to a shift in the center of gravity, enhances the stability of adjacent lower and upper storage boxes, and solves the problem of "easy to tip over and poor stability" in traditional multi-box stacking.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0018] Example 1: Please refer to Figures 1 to 6 : This utility model proposes a moisture-proof storage box for 3D printing consumables, including a lower storage box 1, an upper box 2, and an upper cover 3. A lower grid plate 101 is fixedly installed on the lower inner side of the lower storage box 1. A desiccant storage chamber 102 is opened at the bottom of the lower storage box 1. The desiccant storage chamber 102 is filled with desiccant. The lower end of the desiccant storage chamber 102 is threadedly connected to the central through column 103. Side cover plates 104 are hinged and rotatably connected to both sides of the desiccant storage chamber 102. The side cover plates 104 and the desiccant storage... The chamber 102 is equipped with a card strip and a sealing ring to improve sealing. Side magnetic plates 105 are fixedly connected to both sides of the lower storage box 1. An upper box 2 is located above the lower storage box 1. The desiccant storage chamber 102 is located below the lower grid plate 101. A central through-post 103 and the lower grid plate 101 pass through axially. The central through-post 103 is located inside the lower storage box 1 and is positioned along the height of the lower storage box 1. It is used to pass through the shaft of the 3D printing consumable roll. The lower grid plate 10... 1. A device is used to connect the lower storage box 1 and the desiccant storage chamber 102, allowing the desiccant to absorb moisture inside the lower storage box 1. A lower extension slide 201 is fixedly connected to the lower inner side of the upper box 2, and an outer corrugated sealing ring 202 is fixedly connected to the lower outer side of the upper box 2. An upper cover 3 is slidably connected to the upper part of the upper box 2. A through-hole 301 is arranged in a rectangular array at the bottom of the upper cover 3. A side sealing plate 302 is rotatably connected to the side hinge of the upper cover 3. A desiccant receiving cavity is provided inside the upper cover 3. The cavity is filled with desiccant. The axial clamping force between the upper cover 3 and the upper body 2 after sliding is greater than the weight of the upper body 2. When the bottom of the upper cover 3 is supported by consumables, and because the axial clamping force between the upper cover 3 and the upper body 2 is greater than the weight of the upper body 2 itself, the two will not separate. When the upper cover 3 and the upper body 2 slide, the interior of the upper cover 3 is connected to the interior of the upper body 2 through the lower through hole 301. The desiccant in the cavity of the upper cover 3 is connected to the interior of the upper body 2 through the lower through hole 301 to absorb moisture from the interior space of the upper body 2.
[0019] In this embodiment, the lower extension slide 201 is located inside the outer corrugated sealing ring 202. The lower extension slide 201 slides against the inner side of the lower storage box 1 and slides up and down along the inner wall of the lower storage box 1 to adjust the height of the upper box 2 relative to the lower storage box 1. This allows a single storage box to adapt to dynamic storage needs ranging from small to large capacity, eliminating the need to add additional storage boxes for different capacity requirements. The lower end of the outer corrugated sealing ring 202 is fixedly connected to the lower storage box 1. The upper box 2 and the lower storage box 1 form a radial seal through the outer corrugated sealing ring 202, which always maintains the sealing effect between the upper box 2 and the lower storage box 1.
[0020] In this embodiment, side magnetic plates 105 are fixedly connected to both sides of the upper box 2. The lower storage box 1 and the upper box 2 of the adjacent storage box are magnetically attached and spliced together by the side magnetic plates 105 to form an integrated storage unit, thereby enhancing the stability of the adjacent lower storage box 1 and upper box 2.
[0021] In this second embodiment, based on the first embodiment, side magnetic plates 105 are fixed to the top of the upper box cover 3 and the bottom of the lower storage box 1. The lower storage box 1, which is stacked vertically, achieves auxiliary fixing through the magnetic attraction between the side magnetic plates 105 at the bottom and the side magnetic plates 105 at the top of the upper box cover 3 of the lower storage box, thereby enhancing the stability when stacked vertically.
[0022] The working principle of this embodiment: 3D printing consumables are stored inside the lower storage box 1 and the upper box 2. The consumables are placed above the lower grid plate 101, with a central through-pillar 103 penetrating the middle of the consumables to maintain axial concentricity and improve stability when stacked axially. A dual-zone moisture-proof structure is formed by the "desiccant storage chamber 102 at the bottom of the lower storage box 1 + desiccant receiving cavity inside the upper box cover 3": the desiccant in the desiccant storage chamber 102 continuously absorbs moisture from the lower storage box 1 and the upper box 2 through the grid holes of the lower grid plate 101; the desiccant in the receiving cavity of the upper box cover 3 communicates with the interior of the upper box 2 through the lower through-hole 301 to absorb moisture from the interior space of the upper box 2. The dual-zone desiccant synergy... The same function can quickly reduce relative humidity, effectively avoiding problems such as "filament breakage, air bubbles, and decreased interlayer bonding" caused by moisture absorption in 3D printing consumables, especially moisture-absorbing materials such as PLA and ABS, ensuring the storage stability of consumables and subsequent printing quality; the side cover plate 104 of the desiccant storage chamber 102 achieves chamber sealing through a sealing ring to prevent the desiccant from becoming damp and ineffective; the upper box 2 and the lower storage box 1 form a radial seal through an outer corrugated sealing ring 202, and the upper box cover 3 and the upper box 2 form a circumferential seal through a sealing strip and a sealing gasket of the side sealing plate 302. The fully sealed structure can block the entry of external humid air, while preventing the internal desiccant's moisture absorption capacity from decaying too quickly, extending the desiccant's service life, and further improving the long-term reliability of moisture protection; The upper housing 2 slides up and down along the inner wall of the lower storage housing 1 via the lower extension slide 201, allowing for height adjustment. When more 3D printing consumables need to be stored, the upper housing 2 slides away from the lower storage housing 1 via the lower extension slide 201, and the outer corrugated sealing ring 202 elastically extends simultaneously. While expanding the internal volume, the outer corrugated sealing ring 202 maintains the sealing effect between the upper housing 2 and the lower storage housing 1, preventing sealing failure during expansion. This allows a single storage box to adapt to dynamic storage needs ranging from small to large capacity, eliminating the need for additional storage boxes for different capacity requirements and significantly reducing user purchase costs. To reduce the cost of multiple storage devices, the upper box 2 is compressed in height to be close to the lower storage box 1, thus reducing space occupation and avoiding space waste caused by multiple empty boxes being stacked. After the upper box 2 is expanded, the bottom of the upper box cover 3 is supported by consumables. In order to reduce the possibility of the upper box cover 3 separating from the upper box 2 due to the consumables supporting the upper box cover 3, the lower storage box 1 and the upper box 2 are placed upside down, with the upper box cover 3 at the bottom. The weight of the upper box 2 is used to press the upper box cover 3 tightly, ensuring that the two remain in a sliding and tight state. This avoids the situation where the upper box 2 and the upper box cover 3 become loose due to wear after long-term use, which may cause them to easily separate during normal use. The lower storage box 1 and upper box 2 of adjacent storage boxes are magnetically attached and spliced together by side magnetic plates 105 to form an integrated storage unit. This avoids the situation where the center of gravity of the lower storage box 1 and upper box 2 rises synchronously after the height of the lower storage box 1 and upper box 2 is increased, and the high center of gravity shift makes it easier for them to fall over. This enhances the stability of the adjacent lower storage box 1 and upper box 2 and solves the problem of "easy to tip over and poor stability" of traditional multi-box stacking.
