Definitions

  • the present application relates to the technical field of dust collectors, and for example, relates to a multifunctional dust collector.
  • a dirt storage tank is generally disposed on a machine body or the dirt storage tank for dust is taken as a separate accessory.
  • Such design results in that although the machine body of the hand-held dust collector is designed to be detachable, when the hand-held dust collector is taken down for separate use, it is impossible to directly suck liquid or dust, and other accessories must be added for use, thereby being very inconvenient.
  • the present application provides a multifunctional dust collector which has an optimized structure and can facilitate hand-held operation for dust collection by a user, so as to enable the user to obtain a better use experience.
  • An example of the present application provides a multifunctional dust collector, including: a machine body provided with a dirt storage tank; an electric floor brush pivotably connected to a lower end of the machine body and provided with a detachable cleaning fluid tank; and a hand-held dust collector detachably plugged on an upper end of the machine body and including a dust cylinder assembly, the dust cylinder assembly including a dust-air separation chamber and a dust storage chamber, the dust-air separation chamber and the dust storage chamber being parallel to each other and being independently disposed, and the dust-air separation chamber being positioned upstream of the dust storage chamber; the multifunctional dust collector at least including the following two working modes:
  • connection should be interpreted broadly, for example, either fixed connection or detachable connection, or integral connection; may be mechanical connection or electric connection; and may be direct connection or indirect connection through an intermediate medium, and may be internal communication between two elements or an interaction relationship between two elements.
  • connection should be interpreted broadly, for example, either fixed connection or detachable connection, or integral connection; may be mechanical connection or electric connection; and may be direct connection or indirect connection through an intermediate medium, and may be internal communication between two elements or an interaction relationship between two elements.
  • a first feature being “above” or “below” a second feature may include direct contact between the first feature and the second feature, and may further include contact between the first feature and the second feature through an additional feature between them without direct contact.
  • the first feature being “on”, “above” and “over” the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicates that the first feature is at a higher level than the second feature.
  • the first feature being “under”, “below” and “beneath” the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicates that the first feature is at a lower level than the second feature.
  • the terms “upper”, “lower”, “left”, “right” and other orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings for ease of description and simplicity of operation only and do not indicate or imply that the referenced devices or elements must have a particular orientation, or be constructed and operated in a particular orientation.
  • the terms “first” and “second” are used merely to distinguish one from another in a descriptive sense without special meanings.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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).
  • 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).
  • the cleaning fluid tank 4 is disposed in a cleaning fluid supply assembly
  • 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.
  • 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.
  • 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.
  • the dust collector in the present application at least includes the following two working modes:
  • the multifunctional dust collector provided in the example of the present application, three functions of floor dust collection, floor rinsing and hand-held dust collection which can be achieved by a plurality of machines in the related art can be achieved only by one machine; the cleaning efficiency is greatly improved by the second-stage fluid separation in the stick type dust collector mode; the use scenarios of the hand-held dust collector 5 is enriched by the hand-held dust collector mode; and the requirements for floor dust collection, floor rinsing and hand-held dust collection of the user are met.
  • the hand-held dust collector 5 further includes a main machine 52, a battery assembly 53 and a handle 54; and the dust cylinder assembly 51 and the main machine 52 are disposed front and back in a fluid direction, a first end of the handle 54 is fixed on the main machine 52, and a second end of the handle 54 is fixed on the battery assembly 53.
  • the first end of the handle 54 is fixed on one side of the machine body 52 and bent backwards to be behind the machine body 52.
  • the handle 54 includes a handle holding section 5411, and the handle holding section 5411 is at least partially or entirely formed on a handle section 541 positioned on a rear portion of the main machine 52.
