Separating device for separating dust and water mixture and ground cleaning machine

Abstract

The invention relates to a separating device for separating a dust and water mixture and a floor cleaning machine, and the separating device for separating the dust and water mixture comprises a shell which is internally provided with a containing cavity; a separator arranged in the containing cavity and divides the containing cavity into a first chamber and a second chamber; the first chamber is provided with an air inlet and an air outlet which are in fluid communication; the separating device is characterized by further comprising a water absorption piece which is arranged on the separator, located in the first chamber and used for absorbing water in the first chamber; a guide pipe assembly used for guiding water in the water absorption piece into the second cavity, wherein the water inlet end of the guide pipe assembly is connected with the water absorption piece, and the water outlet end of the guide pipe assembly is communicated with the second chamber; an air pump arranged to be fixed relative to the shell, wherein the air inlet end of the air pump communicates with the second chamber, and the air outlet end of the air pump does not communicate with the second chamber. The dust and water are effectively separated, water splashing is prevented, and the possibility that dust is attached to the inner wall of the second cavity is reduced.

Description

technical field [0001] The invention belongs to the field of household washing and cleaning, and in particular relates to a separation device and a floor cleaning machine for separating dust and water mixture. Background technique [0002] At present, dust and other mixtures mixed with water vapor on the bottom surface are sucked into the inner cavity of the vacuum cleaner or sweeper. In order to separate the mixture of particles and water vapor, a separation device is usually used for separation. [0003] For example, the Chinese invention patent application "Centrifugal Water Removal Automatic Cleaning and Dust Removal Device", its patent application number is CN201910956844.6 (application publication number is CN110664314A) discloses a centrifugal water removal automatic cleaning and dust removal device, including a vacuum cleaner body, a filter module and Separation module, the filter module includes a filter element and a rotating shaft, a water-absorbing element is arr...

AI Technical Summary

Problems solved by technology

[0004] The above patent separation device (filter module and separation module) realizes the separation of dust and water, but the separation of accumulated water is driven by the motor to drive the water-absorbing parts to rotate rapidly, and the accumulated water moves outward under the action of centrifugal force, and part of the accumulated water If it cannot enter the drainage ring and is distributed in the separation chamber, the dust in the separation chamber will adhere to the inner wall of the separation chamber after contacting the accumulated water and it is difficult to be cleaned.
