The invention provides a portable multifunctional automobile micro-water cleaning and inflating device which comprises a streamline protective casing. The protective casing is provided with a
handle. A
sorption pump, an inflating pump, an air suction motor and an inflating motor are installed below the protective casing. The
sorption pump is connected with an air suction
pipe, the inflating pump is connected with an inflating
pipe, and the inflating
pipe and the air suction pipe are arranged in parallel after entering the protective casing. The inflating pipe is inserted in the air suction pipe when close to an
external interface, the
insertion opening position is in sealed connection, and the air suction pipe and the inflating pipe jointly extend to the position of the
external interface to form a 'double-pipe sleeved' mode. An ultrasonic
nebulizer and a water tank are installed below the outside of the protective casing, and a joint of a mist discharging pipe of the ultrasonic
nebulizer and the inflating pipe is connected with a heating grid. The device further comprises a dust collection box and a multifunctional connector. The water tank, the heating grid, the ultrasonic
nebulizer, an LED illuminating lamp, the inflating motor and the air suction motor are electrically connected with a single-
chip microcomputer. The portable multifunctional automobile micro-water cleaning and inflating device has the advantages of being simple in structure, washing a vehicle conveniently, being more diversified in function and saving water.
