The housing assembly (3) comprises a housing (31), and a first heating blanket (32) in close contact with an inner side of the housing (31). The housing (31) is made of a metal material and is provided with a first slot (3123) which enables the urea solution to enter. The first heating blanket (32) surrounds the periphery of the pump assembly (2) and is connected to the circuit board (131).
