[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] Example 1

[0037] like Figure 1-8 As shown, this utility model discloses a multi-functional moisture-proof cabinet for 3D printers, including a cabinet door 7, side panels 3, back panel 8, top panel 1, bottom panel 4, bottom support 15, middle panel 6, and dehumidifier 9. The cabinet door is equipped with an LCD screen or touch screen 20, and the cabinet body is equipped with a temperature and humidity sensor (not shown in the figure).

[0038] The cabinet door features an extra-large transparent window in the middle, accounting for over 90% of the front area. It is made of highly transparent material, allowing for a clear view of the internal materials.

[0039] The cabinet door is equipped with a smart display screen, which displays digital information and operation buttons, with a simple overall layout.

[0040] The smart display can be a touch screen, i.e., a touch screen, and button controls can be performed via touch.

[0041] Existing devices often feature a rigid, right-angled design, lacking the sophistication and visual appeal expected of high-end products, and failing to meet users' demands for devices that combine functionality and aesthetics. This invention addresses this by employing a large-radius rounded corner design for the window frame, with a radius ≥20mm, eliminating the harshness and creating a smooth, rounded visual effect.

[0042] The main body of the cabinet is a cool gray-white, which contrasts sharply with the black frame and transparent window, creating a simple and modern style.

[0043] The left and right views are completely symmetrical, showing the side of the white cabinet with no extra protruding structures, and the overall shape is rectangular.

[0044] The bottom view shows a rounded rectangular structure with a simple bottom design and no complicated decorations; the bottom of the cabinet is equipped with a bottom support 15, which can be made of anti-slip pads or support feet.

[0045] The cabinet has a middle plate 6 in the middle, which divides the cabinet into upper and lower parts. The bottom is used to store 3D printing line rollers 5. A dehumidifier 9 is located behind the bottom. A grid plate 10 is located on the top and front of the space where the dehumidifier 9 is located. The grid plate 10 has perforated grids.

[0046] The middle plate 6 has a through hole 14 on the side away from the cabinet door. The through hole 14 connects the upper and lower parts of the cabinet body, allowing the air in the upper part to communicate with the dehumidifier 9.

[0047] The middle plate 6 has several longitudinally arranged long grooves 11, which are parallel to the side plate 3. Two freely rotating sliding rollers 12 are arranged on the inner side of the long grooves 11. The sliding rollers 12 are connected to the inner wall of the long grooves 11 by bearings. The sliding rollers 12 have a groove 121 in the middle of the transverse direction. The two protruding ribs 51 on both sides of the 3D printing filament roller 5 are located on the two sliding rollers 12 respectively. The filament is wound on the 3D printing filament roller 5 and pulled out under the drive of the 3D printer. The 3D printing filament roller 5 rotates on the sliding roller 12 around its central axis.

[0048] A baffle 13 is covering the lower part of the long groove 11, and the baffle 13 is connected to the intermediate plate 6.

[0049] Existing dehumidifying cabinets only have doors. During the 3D printing process, the doors are open, resulting in longer printing times and a tendency for moisture to seep back in, making the indoor environment drier in winter and causing energy waste. This utility model addresses this by providing an upper door 16 and a lower door 17 on the upper chamber of the middle plate 6, respectively. Both doors 16 and 17 are made of transparent glass to allow observation of the cabinet interior. The upper door 16 has a hole 161 through which the filament thread passes.

[0050] Moisture-absorbing boxes 18 are respectively installed on the inner side of the two side panels 3 near the cabinet door. Each moisture-absorbing box 18 includes a shell with multiple ventilation holes having a diameter smaller than that of the consumable material. The moisture-absorbing box contains moisture-absorbing substances such as color-changing silica gel and activated carbon. The moisture-absorbing boxes 18, in conjunction with the dehumidifier 9, can keep the air dry, reduce energy consumption, ensure continuous printing by the 3D printer without moisture affecting the material, and guarantee print quality.

[0051] During the 3D printing process, open cabinet door 7, close upper door 16 and lower door 17, and lead out the filament through hole 161 to connect to the 3D printer.

[0052] This utility model can replace traditional tripods, shelves, and non-standard feeding mechanisms, integrating material storage and feeding functions to improve the standardization and efficiency of material management; the extra-large window makes the material status "clear at a glance", making it easy for users to keep track of the material status in real time.

[0053] Example 2

[0054] like Figure 9-12 As shown, this embodiment discloses a multi-functional dehumidifying cabinet for 3D printers. Unlike embodiment 1, the cabinet is smaller in size, saving costs. This embodiment does not have a middle plate, and the dehumidifier 9 is located at the rear of the cabinet. The 3D printing filament roller 5, located above the long groove 11, is placed in front of the dehumidifier 9. A space for storing the 3D printing filament roller 5 is provided in front of the long groove 11. When storing, the 3D printing filament roller 5 is stacked on its side. In use, the stored 3D printing filament roller 5 is removed, and the filament on the 3D printing filament roller 5 above the sliding roller 12 on the inner side of the long groove 11 is connected to the 3D printer. Under the traction of the 3D printer, the 3D printing filament roller 5 rotates, drawing out the filament.

[0055] In this embodiment, the dehumidifier 9 is located behind the long trough 11 and connected to the back plate 8. The dehumidifier 9 does not have a grid plate 10 on its outer side.

[0056] The cabinet door 7 has an inner door 19 on its inner side, and the inner door 19 has a hole 191 through which the consumable wire passes.
