Definitions

  • the present invention relates to the field of household appliances, in particular to a cleaning device, such as a vacuum cleaner, a mopping apparatus or a floor sweeper.
  • a cleaning device such as a vacuum cleaner, a mopping apparatus or a floor sweeper.
  • Cleaning devices are generally fitted with a dust bin for collecting dust and other dirt.
  • a fluid communication duct is generally provided between the dust bin and a body of the device, the duct allowing air or dust and other dirt to pass through.
  • a sealing member may be provided at the position of connection between the dust bin and the device body to prevent outward leakage of gases or dust.
  • Existing sealing members are quite complex in structure, and usually need to be fitted to both the device body and the dust bin by insertion, in order to ensure sealing quality, but such a configuration makes removal of the dust bin from the device body inconvenient. Sealing members which are structurally simple can be envisaged, but structurally simple sealing members are likely to result in a poor sealing effect, fatigue damage after a long period of use, and so on.
  • existing cleaning devices have room for improvement in other respects, for example: there are few alignment feature structures between the dust bin and the device body, so deviation from the correct installation position is likely to occur in the process of installing the dust bin; a sealing structure between a handle and the device body is overly complex, making removal of the handle from the device difficult; a connection structure for fitting a cleaning fluid tank, used for holding cleaning fluid, to the device is difficult to operate; a mounting bracket for a vibrating component motor has too simple a structure, so the motor is easily damaged in use and has a short service life; and a suction cleaning part of the cleaning device contains complex ducts and electric wires, so components for accommodating or carrying these ducts and electric wires usually need to be additionally provided, which increases the overall volume of the structure as well as the manufacturing cost.
  • the present invention provides a cleaning device, with a sealing member provided in a region of connection of a body part and a dust collection component of the cleaning device, a cross section of an elastic force application portion of the sealing member being formed in an arc shape, thereby enabling a good sealing effect while also facilitating installation and removal of the dust collection component; moreover, the sealing member has a two-layer elastic wall structure and is therefore not likely to deform even with long-term use.
  • the cleaning device of the present invention also provides preferred configurations in other respects; for example, the present invention additionally provides an alignment structure between the dust collection component and a device body, further avoiding problems such as rocking and shifting during installation of the dust collection component; improves a sealing structure between a handle and the device body, facilitating installation and removal of the handle; improves an installation connection structure of a cleaning fluid storage tank and the device body, facilitating installation and removal of the cleaning fluid storage tank; improves the structure of a motor mounting bracket, avoiding excessive rocking of the motor during use, and thus being able to effectively extend the motor service life; and integrates part of a wall face of a cleaning apparatus with a part for accommodating and carrying electric wires, ducts and other structures, thus saving space and reducing manufacturing costs.

This cross section is jointly defined by an axis X2 of the installation post and the axis D1 of the tubular structures formed by the wing parts 473, 474, and the two wing parts 473, 474 are shown in the sectional drawing.
  • wing parts 473, 474 are received in corresponding accommodating parts 223 in the body top portion 21. Since the wing parts 473, 474 are tube structures and the accommodating parts 223 are cylindrical receiving cavities, the retainer 47 is rotatable as a whole through a certain angle about direction D1 (see Fig. 12 ), and this facilitates installation and removal of the cleaning fluid storage means 40. It will be understood that the pivoting and rocking of the retainer 47 used for receiving the cleaning fluid storage means 40 can provide an optimal engagement angle, facilitating alignment of the cleaning fluid storage means 40.
  • the pair of wing parts 473, 474 have different diameters, and a bottom surface of the wing part 473 with the larger diameter is flush with a bottom surface of a body of the retainer 47.
  • a motor 52 for providing vibration for the cleaning apparatus 50 is installed in the cleaning apparatus 50.
