[0008] Preferably, the stirring mechanism includes a rotating rod, a plurality of stirring rods and a driven gear. The rotating rod is rotatably connected to the lower surface of the support plate and is located inside the filter barrel. Each of the stirring rods is symmetrically fixedly connected to the rod wall of the rotating rod. The upper end of the rotating rod passes through the lower surface of the support plate, and the driven gear is fixedly sleeved on the rod wall at the upper end of the rotating rod.

[0025] The centrifugal force generated by rotating the filter barrel 3 can cause the DPF detergent inside the filter barrel 3 to be thrown out, thereby increasing the speed at which the DPF detergent passes through the filter barrel 3 and improving the efficiency of DPF detergent filtering.

[0026] In order to speed up the process of DPF cleaner preparation, Figure 1 , Figure 2 As shown, the stirring mechanism includes a rotating rod 6, a plurality of stirring rods 7 and a driven gear 8.

[0027] The cylinder 9 is started to mesh the driving gear 11 with the driven gear 8, and then the motor 10 is started. Then, the rotating rod 6 can be rotated through the transmission of the driving gear 11 and the driven gear 8, so that each stirring rod 7 stirs the reactant, thereby accelerating the preparation process of the DPF cleaner.
