The operation method comprises the following steps: automatic boil powder machine and carry out during operation at first put into interior powder storehouse 501 with the powder, promote regulating block 1502 and make interior powder storehouse 501 coincide with the drainage hole 903 of outer powder storehouse 502 mutually, valve 13 closes, and the start power passes through water in the suction pump 902 with the water storage box and lets in powder storehouse 5 by inner bag 4 in, reaches certain inflow under the controller effect, and suction pump 902 self-closing carries out the bubble to the powder and sends out. After the foaming is finished, the heating element 6 is started to heat the water in the inner container 4 (or the water is changed and then the heating is carried out), so that the powder boiling is realized. After the powder is boiled, if edible dry powder fishing is selected, the handle sleeve 1507 is directly lifted, water in the powder bin 5 is discharged, the valve 13 is opened, and the water flows into the waste water barrel 8 through the water outlet 11 of the inner container 4; when the soup powder is to be selected for eating, the adjusting block 1502 is pushed, the limiting block 1501 is moved to the other end of the groove 1505, the water filtering holes 903 of the inner powder bin 501 and the outer powder bin 502 are shielded by the side walls of the opposite sides, the soup in the inner powder bin 501 is reserved, the soup powder in the inner powder bin 501 is poured out, and seasoning is added for eating. Then the diaphragm pump is started to add water into the inner container 4, the cleaning effect is achieved through the high-frequency vibration of the ultrasonic cleaner at the bottom of the inner container 4, and finally the water in the inner container 4 is discharged into the waste water tank at the bottom through the valve 13.
