The invention discloses an integral irrigation suction device. The device comprises a nozzle assembly, an outer tube, an inner tube, a handle assembly, a first valve and a second valve, wherein the nozzle assembly comprises an outlet tube connecting sleeve and a first inner tube connecting sleeve; the handle assembly comprises a handle body and a negative pressure control part; the negative pressure control part is provided with an air inlet; the nozzle assembly, the outer tube and the inner tube are integrally molded by plastic; and the handle assembly is formed by left and right half-bodies which are symmetric and are fixedly connected. When the integral irrigation suction device is used, the air inlet is pressed by a thumb, an external negative pressure source is opened, the first valve is opened, and a to-be-irrigated position is irrigated by water; the front end of the connecting sleeve out of the nozzle assembly is conical, so that ejected water is accumulated to a point in front of a suction hole; the suction hole of the nozzle assembly is aligned to the to-be-irrigated position, stains attached to the surface of the to-be-irrigated position can be sucked into the irrigation suction device through the suction opening of a water spray assembly; and the second valve is opened, and the stains can be irrigated out of the irrigation suction device by water.
