[0031] Example

[0032] See also Figures 1 to 5 The present embodiment provides a 3D printing material dry storage box, comprising a bottom shell 1 and a top cover 2, one end of the top cover 2 is hinged to one end of the bottom shell 1, an arc-shaped top cover electric heating plate 21 is provided on the inner side of the top cover 2, and an arc-shaped bottom shell electric heating plate 11 is provided on the inner side of the bottom shell 1. When the top cover 2 is covered on the bottom shell 1, a main body cavity for accommodating a material tray 3 is formed between the top cover 2 and the bottom shell 1, and the top cover electric heating plate 21 and the bottom shell electric heating plate 11 can form an annular heating circle around the material tray.

[0033] In this embodiment, a control board 12 is further provided in the bottom shell 1, and the control board 12 is electrically connected to the bottom shell electric heating plate 11 and the top cover electric heating plate 21 respectively. The material tray 3 wrapped with 3D printing material is placed in the storage box, and the top cover 2 is covered on the bottom shell 1, so that a relatively closed main body cavity can be formed between the top cover 2 and the bottom shell 1. The control board 3 is used to supply power to the bottom shell electric heating plate 11 and the top cover electric heating plate 21, so that the bottom shell electric heating plate 11 and the top cover electric heating plate 21 generate heat, thereby enabling a 360-degree all-round drying operation of the 3D printing material contained in the main body cavity.

[0034] In one embodiment, the types of the top cover electric heater 21 and the bottom shell electric heater 11 are improved to ensure a better drying effect. Specifically, the top cover electric heater 21 and the bottom shell electric heater 11 are both PI heating sheet metal sheets.

[0035] In this embodiment, the use of PI heating sheet metal can ensure the structural stability and reliability of the electric heater, ensure the heating effect and ensure that no deformation will occur during the heating work.

[0036] In one embodiment, the structure of the storage box is improved to ensure a better drying effect. Specifically, the bottom shell 1 is provided with a turbo fan 13, and the bottom shell electric heating plate 11 is provided with a avoidance hole 111 corresponding to the air outlet of the turbo fan.

[0037] In this embodiment, a turbofan 13 is further provided in the bottom shell 1 of the storage box, and the turbofan 13 is connected to the control board 12. The bottom shell electric heating plate 11 is provided with an avoidance hole 111 corresponding to the air outlet of the turbofan 13. The wind blown by the turbofan 13 can circulate the hot air along the inner surface of the bottom shell electric heating plate 11 to the top cover electric heating plate 21, thereby providing a better drying effect for the 3D printing materials.

[0038] In order to absorb excess moisture, a replaceable desiccant is provided in the bottom shell. The desiccant absorbs moisture in the hot air to enhance the drying and dehumidifying effect of the storage box. Excess water vapor can be discharged to the outside of the storage box through the reserved exhaust holes.

[0039] In one embodiment, the structure of the storage box is improved to provide better operational convenience. Specifically, the bottom shell 2 is provided with a touch screen 4, and the touch screen 4 is arranged at an angle with the horizontal plane.

[0040] In the present embodiment, the bottom shell 1 is provided with an opening at one end away from the hinged connection between the bottom shell 1 and the top cover 2. A control panel accommodating cavity isolated from the main body cavity is provided in the bottom shell 1. Isolation from the main body cavity can prevent the control panel 12 and the touch screen 4 from being affected by the heat in the main body cavity. The control panel accommodating cavity is connected with the outside through the opening. A screen fixing bracket is provided in the control panel accommodating cavity. The touch screen 4 is fixed at the opening through the screen fixing bracket. The touch screen 4 is connected to the control panel 12 through a cable. Corresponding instructions can be input through the touch screen 4 to allow the control panel to implement corresponding functional control.

[0041] The opening cooperates with the screen fixing bracket to allow the touch screen 4 to be set at an angle with the horizontal plane. When the storage box is placed on the desktop, the touch screen 4 can be placed at a suitable angle toward the user, which is convenient for the user to operate. At the same time, the control board 12 can also be fixed to the screen fixing bracket by screws to save the internal space of the storage box. Preferably, the angle between the touch screen 4 and the horizontal plane is 40-50°. In this embodiment, the angle between the touch screen 4 and the horizontal plane is 45°.

[0042] In one embodiment, the structure of the storage box is improved to ensure that the storage box can work more safely and reliably. Specifically, the main body cavity is provided with a temperature and humidity sensor 14.

[0043] In this embodiment, the temperature and humidity sensor 14 is connected to the control board 12 inside the bottom shell 1. The control board 12 can obtain the temperature and humidity information in the main cavity of the storage box by obtaining data from the temperature and humidity sensor 14, and display the relevant information on the touch screen 4 for the user to view.

[0044] When the internal temperature is higher than the user's preset temperature and continues to rise, the control panel 12 can cut off the power supply in time to avoid material damage or even spontaneous combustion of the storage box caused by the continuous increase in temperature.

[0045] In one embodiment, the structure of the storage box is designed to ensure that the storage box can provide 3D printing material usage information for user reference in a timely manner. Specifically, a bottom plate 15 is provided at the bottom of the bottom shell 1, and a foot 151 is provided at each of the four corners of the bottom plate. A weighing sensor 152 is provided between the foot 151 and the bottom plate 15.

[0046] In the present embodiment, in order to facilitate users to timely understand the usage status of 3D printing materials, a bottom plate 15 is provided at the bottom of the bottom shell 1, and a foot 151 is provided at each of the four corners of the bottom plate 15. A weighing sensor 152 is provided between the foot 151 and the bottom plate 15. The weighing sensor 152 is connected to the control board 12. The control board 12 can obtain the real-time weight and remaining length of the 3D printing material and other information through the data of the weighing sensor 152 and the program algorithm, and display the relevant information on the touch screen 4 for the user to consult.

[0047] In order to prevent the temperature and humidity changes in the main cavity from affecting the load sensor 152, a thermal insulation cotton 153 is attached to the side of the bottom plate 15 close to the main cavity. The thermal insulation cotton 153 can not only isolate the load sensor 152 from the high temperature of the main cavity, but also insulate the main cavity.

[0048] In one embodiment, the structure of the top cover 2 is improved to prevent the user from being scalded. Specifically, the top cover 2 is provided with an anti-scalding guard plate 22.

[0049] In the present embodiment, an anti-scalding guard plate 22 is provided on the inner side of the top cover 2 away from the end where the top cover 2 is hinged with the bottom shell 1. The anti-scalding guard plate 22 is fixed to the fixing column of the top cover 2 by screws and is at a distance from the top cover electric heater 21. When the user opens the top cover 2, it can effectively prevent the user from accidentally directly touching the top cover electric heater 21 in the top cover 2 and getting burned, thereby greatly improving the safety of the storage box.

[0050] In one embodiment, the structure of the storage box is improved to facilitate the release of the 3D printing material from the material tray. Specifically, the bottom shell 1 is provided with a roller 16 .

[0051] In this embodiment, in order to facilitate the release of the 3D printing material by the material tray 3, two parallel rollers 16 are provided in the bottom shell 1. The two rollers 16 can support the material tray. By allowing the material tray 3 to release the 3D printing material by rolling on the rollers 16, the rotational resistance of the material tray 3 can be effectively reduced.

[0052] In order to further reduce the rolling friction coefficient of the material tray 3, bearing grooves are provided on both sides of the bottom shell 1, and flange bearings 161 are provided in the bearing grooves. The roller 16 is inserted in the inner ring of the flange bearing 161, which further reduces the rolling resistance of the material tray 3 and makes the extraction of 3D printing materials from the material tray 3 smoother.

[0053] In one embodiment, the material of the top cover 2 is improved to facilitate the use of the storage box. Specifically, the top cover 2 is made of a transparent material / semi-transparent material.

[0054] In this embodiment, the top cover 2 supported by transparent material / semi-transparent material can allow the user to intuitively observe the usage of the 3D printing material in the main body cavity.

[0055] From the above description, it can be seen that the beneficial effect of the utility model is that it provides a 3D printing material storage box with electric heating plates on both the top cover and the bottom shell, and the material box placed in the storage box and wrapped with 3D printing materials is evenly heated by the two electric heating plates, with good heating efficiency, stable temperature, and better drying effect on 3D printing materials.

[0056] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
