[0024] A liquid storage box 60 is fixed at the bottom of the reaction barrel 10 , and a drying box 50 is fixed on one side of the liquid storage box 60 .

[0025] It should be noted that, in the embodiment, the rotating motor 31 drives the rotating disk 32 and the fixed block 36 to rotate, thereby driving the sliding rod 33 and the fan gear 34 to rotate, and then driving the rack 35 to slide back and forth, so that the nano powder in the hemispherical discharge shell 40 leaks out.

[0026] For example, please refer to Figure 2-3 The spraying device 20 includes a passivation liquid tank 21 connected to one side of the reaction barrel 10, a water pump 22 connected to one side of the passivation liquid tank 21, an evaporator 23 connected to one side of the water pump 22, and a nozzle 24 connected to one side of the evaporator 23.

[0027] It should be noted that, in the embodiment, the water pump 22 allows the passivation liquid in the passivation liquid tank 21 to enter the evaporator 23, so that the passivation liquid is converted into gas, and enters the reaction barrel 10 through the nozzle 24 to react with the nano powder.

[0028] For example, please refer to Figure 1-2 A feed inlet 11 is provided on one side of the top of the reaction barrel 10 , and a sealing cover 70 is installed on the top of the feed inlet 11 .
