As an embodiment of the invention, the lower end of the supporting column 14 is fixedly connected with a supporting cushion block 13, and the lower surface of the supporting cushion block 13 is provided with anti-skid grains; during operation, through the anti-skidding line that sets up, increase frictional force makes the lip block 13 more stable when supporting.

In operation, when the full-color 3D printer body 1 prints, the fan 4 is started, the fan 4 performs air draft through the first air draft pipe 3 and the second air draft pipe 10, the peculiar smell gas and part of printing raw material impurities in the printing process are pumped into the second air draft pipe 10 through the through cavity 9, and then are input into the first cavity 23 of the purifying box 16 through the air pipe 5 and combined with the mixed solution of ferrous sulfate and rice vinegar, the impurity particle substances can be filtered and removed better and faster through the mixed solution of ferrous sulfate and rice vinegar, the cleaning effect is improved, meanwhile, lead is contained in the peculiar smell gas, toxic objects such as arsenic and the like react with ferrous sulfate and rice vinegar to generate precipitates, the peculiar smell gas and part of printing raw material impurities can be effectively treated through the mixed solution of ferrous sulfate and rice vinegar, thereby further reducing the working pressure of the active carbon 17, the peculiar smell gas flows into the gas distribution groove 34 through the hose 22, the odor is sprayed out through the air distributing holes, simultaneously, after the fan 4 is started, the motor 18 rotates to drive the driving disc 19 to rotate, the air distributing disc 32 is driven to rotate in the rotating process of the driving disc 19, the activated carbon 17 is stirred, meanwhile, odor gas can be uniformly scattered in the activated carbon 17, and the gas is discharged through the gas outlet pipe 21 after being purified, so that the influence of odor emission on the processing environment is avoided, the body health of an operator is benefited, the replacement of the activated carbon 17 in the purifying box 16 is facilitated through the arranged sealing door 6, the operator can conveniently observe the use condition of the activated carbon 17 in the purifying box 16 and the precipitation condition of particle impurities in the first cavity 23 through the arranged observation window 15, and the impurities can be conveniently and timely cleaned and the activated carbon 17 can be conveniently replaced;

fan 4 bleeds the in-process, peculiar smell gas and part print raw materials impurity, when through exhaust tube two 10, because the effect of sealed piece 26, make peculiar smell gas and part print raw materials impurity get into in collecting vat 27, arc setting through collecting vat 27 can make print raw materials impurity deposit in collecting vat 27 bottom, after the printing is accomplished, through starting heating block 29, print raw materials impurity after the heating solidification, make the print raw materials impurity after the solidification liquefy again, and extract the rubber buffer, make the print raw materials impurity after the liquefaction flow out and collect.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
