[0050] Specifically, the inside space is scientifically divided into the element cavity 12 and the wiring cavity 13 by arranging the partition plate 11 in the box body 1, which realizes the physical isolation of the heating system and the control system, effectively prevents the influence of high temperature on the electrical elements, and reduces the safety hazards such as electric leakage; in addition, the threading groove 15 formed in the partition plate 11 and the bottom of the box body 1 facilitates the standard arrangement of various lines, and improves the overall safety and maintenance convenience of the equipment.

[0056] The heat conducting pipe 34 is integrally connected to the top of the air guide shell 33;
[0057] The fan 35 is installed between the bottom of the heating box 31 and the inner bottom surface of the element cavity 12.
[0058] Specifically, the drying mechanism 3 adopts a multi-stage heating system design of the heating box 31, the electric heating wire 32, the air guide shell 33, the heat conducting pipe 34 and the fan 35, forming a complete heat transfer and circulation system. The heating box 31 provides a stable heat source for the whole system, the heat generated by the electric heating wire 32 forms a heat conduction channel through the air guide shell 33 and the heat conducting pipe 34, and the fan 35 at the bottom generates forced convection to push the hot air to flow in the system. This design of multiple components working together not only improves the heating efficiency, but also ensures uniform heating of the consumables and avoids the problem of local overheating or insufficient heating. The whole drying system is compact in structure and easy to install, and can realize rapid and efficient drying of the consumables.

Specifically, the consumable pipe 2 is fixedly arranged inside the heat conducting pipe 34, and the air inlet 21 is provided at the bottom of the consumable pipe 2 and connected with the top of the air guide shell 33, forming a complete hot air channel. This design makes the hot air fully contact the surface of the consumables, improves the heat transfer efficiency, and the annular plugs 22 at both ends not only play a sealing role to prevent heat loss, but also ensure the smooth passage of the consumables, facilitating the loading and unloading of the consumables. The whole structure design not only ensures the drying effect, but also improves the practicability and operation convenience of the equipment.
[0061] Specifically, the inner wall of the annular plug 22 is provided with a polytetrafluoroethylene coating.
[0062] Referring to the drawings attached to the specification Figures 3-5A plurality of groups of strip-shaped air grooves 14 are formed in the bottom of the box body 1 and correspond to the positions of the fans 35. Specifically, the plurality of groups of strip-shaped air grooves 14 correspond to the positions of the fans 35, forming a scientific air inlet system. This design not only ensures that the system obtains sufficient air intake to provide power for heat circulation, but also promotes heat dissipation of the equipment to prevent the system from overheating. The reasonable ventilation design improves the drying efficiency and prolongs the service life of the equipment, ensuring the continuous and stable operation of the drying system.
[0063] Referring to the drawings Figures 1-2 and the drawings Figure 4 A plurality of groups of moisture removal holes 4 are formed equidistantly in the top of the box body 1, the top of the consumable tube 2, and the top of the heat conduction pipe 34, and the moisture removal holes 4 have a circular truncated cone structure. Specifically, the plurality of groups of circular truncated cone-shaped moisture removal holes 4 are formed equidistantly in the top of the box body 1, the top of the consumable tube 2, and the top of the heat conduction pipe 34. This design provides an effective exhaust channel for the water vapor generated during the drying process.

[0065] Specifically, in use, the present application can also be directly installed on a 3D printer. By performing real-time drying before the consumables pass through the consumable tube 2 to the print head, no additional pretreatment process is required. This design not only saves equipment investment costs, but also simplifies the operation process, improves production efficiency, and effectively saves workspace due to the compact structure design, making it suitable for various 3D printing application scenarios of all scales.
