[0012] Referring to FIG. 1 to FIG. 8, a multifunctional dust collector (for example, the multifunctional dust collector may be a dry and wet dual-purpose multifunctional hand-held stick type dust collector with three-in-one of floor dust collection, floor rinsing and hand-held dust collection) provided in an example of the present application includes: a machine body 1, a dirt storage tank 2, an electric floor brush 3, a cleaning fluid tank 4 and a hand-held dust collector 5.
[0013] The hand-held dust collector 5 is detachably plugged on the machine body 1, for example, the hand-held dust collector 5 is positioned at an upper end of the machine body 1. The machine body 1 is provided with a dirt storage tank 2; and the electric floor brush 3 is pivotably connected to a lower end of the machine body 1 and provided with a detachable cleaning fluid tank 4. When the multifunctional hand-held stick type dust collector runs, it is necessary to mount the hand-held dust collector 5, and the hand-held dust collector 5 is disposed to extract and collect dirt from a surface to be cleaned.
[0014] The hand-held dust collector 5 includes: a dust cylinder assembly 51, wherein the dust cylinder assembly 51 includes a dust-air separation chamber 511 and a dust storage chamber 512, the dust-air separation chamber 511 and the dust storage chamber 512 are parallel to each other and are independently disposed, and the dust-air separation chamber 511 is positioned upstream of the dust storage chamber 512.
[0015] It should be noted that the fluid in the present application may be clean airflow, and may also be airflow entrained with dirt; and the dirt is at least one of dust, solid contaminants (such as cigarette ends, scraps of paper, and rice grains), and soiling solutions (such as orange juice, dirty water, and egg liquid).
[0016] In one of the examples, the cleaning fluid tank 4 is disposed in a cleaning fluid supply assembly, and the cleaning fluid supply assembly may further include a spray nozzle and a pump, wherein the pump is disposed to guide a cleaning fluid from the cleaning fluid tank 4 to the spray nozzle, and the spray nozzle, as an output tail end of the cleaning fluid supply assembly, sprays or guides the cleaning fluid to a rolling brush of the electric floor brush 3 or a floor, so as to wet dirt on the floor, and facilitate picking and collection of the dirt by the dust collector.
[0017] Illustratively, the cleaning fluid tank 4 is detachably mounted on the electric floor brush 3, and by disposing the cleaning fluid tank 4 on the electric floor brush 3, there is no need to dispose a relatively long cleaning fluid water pipe, and a spraying response is relatively fast; in addition, the electric floor brush 3 is weighted to increase a force for pressing down the floor, so that a cleaning effect can be improved.
[0018] In one of the examples, the cleaning fluid tank 4 is detachably mounted on the machine body 1, and by disposing the cleaning fluid tank 4 on the machine body 1, for example, disposing the cleaning fluid tank 4 on a rear side of the machine body 1, and disposing the cleaning fluid tank 4 symmetrically with the dirt storage tank 2, the weight of a complete machine may be uniform, and the use experience of a user may be improved.
[0019] The dust collector in the present application at least includes the following two working modes:
a stick type dust collector mode, wherein the hand-held dust collector 5 is connected to the upper end of the machine body 1 by plugging and bonding, under the action of a suction force of the hand-held dust collector 5, a fluid entrained with dirt enters the dirt storage tank 2 from a suction inlet of the electric floor brush 3 for first-stage fluid separation, and at least one of dust and liquid is stored in the dirt storage tank 2; and the fluid after the first-stage separation enters the dust cylinder assembly 51 through a fluid channel in the machine body 1 for second-stage fluid separation, and separated clean air is discharged from an air outlet of the hand-held dust collector 5; and
a hand-held dust collector mode, wherein the hand-held dust collector 5 is unlocked and separated from the upper end of the machine body 1 and used alone, under the action of the suction force of the hand-held dust collector 5, a fluid entrained with dirt enters the dust-air separation chamber 511 of the dust cylinder assembly 51 from an air inlet of the hand-held dust collector 5 for dust-air separation, separated dust is stored in the dust storage chamber 512, and clean air is discharged from the air outlet of the hand-held dust collector 5.
