[0007] Furthermore, a non-slip pad is bonded to the outer wall of the bottom of the tank body.

[0008] Furthermore, a display screen is fixedly connected to an outer wall of one side of the tank body.

[0009] Furthermore, two filter screens are clamped in the filter box.

[0010] Furthermore, a sealing ring is clamped at the top end of the water inlet pipe.

[0011] Furthermore, a pull ring is fixedly connected to the top of the sealing cover.

[0012] Furthermore, a nitrogen oxygen sensor is fixedly connected to the top outer wall of the tank body, and the nitrogen oxygen sensor is electrically connected to the display screen.

[0013] The beneficial effects of the utility model are:

[0014] 1. Perform preliminary filtration of the exhaust gas through the filter screen in the filter box to facilitate subsequent treatment and improve the efficiency of exhaust gas treatment.

[0015] 2. The second through hole of the conical plate allows the exhaust gas to be evenly dispersed in the automotive urea liquid, thereby better treating the exhaust gas and improving the treatment effect of the exhaust gas. BRIEF DESCRIPTION OF THE DRAWINGS
