[0020] Continuously referring to Figures 1 to 3 , the water storage part 3 is annular, an annular cavity is arranged in the water storage part 3, the first spraying part 41 and the second spraying part 42 are both annular, the first spraying part 41 is arranged at the inner ring of the water storage part 3, and the second spraying part 42 is arranged at the outer ring of the water storage part 3, the water storage part 3 is made of stainless steel or rubber, a soaking degree detection part 5 is arranged at the bottom of the filter core 1, and the soaking degree detection part 5 is a wet sensitive resistor.

[0021] The filter core soaking device for the 3D printer filtering system provided by the embodiment first arranges a filter core body and a soaking device body, wherein the soaking device body is an improved point compared with the prior art, the filter core body, a filter cartridge for arranging the filter core body and a water inlet at the top of the filter cartridge are all prior art, specifically, the soaking device comprises a water storage part and a spraying assembly, the spraying assembly comprises a first spraying part and a second spraying part, the water storage part is used for storing liquid injected from the water inlet, and the first spraying part and the second spraying part are used for guiding water in the water storage part and spraying the inner wall and the outer wall of the filter core, further, the first spraying part and the second spraying part are two annular nozzles, the first spraying part is used for spraying the top of the inner wall of the annular filter core, the second spraying part is used for spraying the top of the outer wall of the annular filter core, liquid starts to soak from the top of the filter core and spreads downward, when the resistance value of the wet sensitive resistor at the bottom of the filter core changes, it indicates that the filter core is completely soaked, at this time, water injection into the water inlet is stopped, and then the filter core can be replaced.

[0022] Therefore, compared with the prior art, the soaking device is additionally arranged at the top of the filter core, the surface of the filter core is locally soaked, drainage and drying treatment are not needed, and the working efficiency is improved.

[0023] Embodiment two:

[0024] Referring toFigures 1 to 3 The figure shows a filter core soaking device for a 3D printer filtering system provided by the second embodiment of the present application. The second embodiment is further improved on the basis of the above-mentioned embodiments, and the technical solutions are as follows: the water storage component and the spraying assembly in the first embodiment are both selected as a circular ring structure, which is used to adapt to the circular ring-shaped filter core, so that the spraying assembly can spray liquid more uniformly around the filter core.
