Description

Quick-release locking structure for floor brush of cleaning machine

Technical Field

The utility model relates to the field of household cleaning tools, in particular to a cleaning machine, and particularly relates to a quick-release locking structure for a floor brush of the cleaning machine.

Background

With the development of household cleaning technology, household cleaning equipment is gradually diversified, and more cleaning equipment is introduced into thousands of households. The traditional dust collector has certain use limitation, and the structural design and the sealing performance of parts of the traditional dust collector can only meet the use scene of a dry environment but cannot be used in a wet environment; when the motor is in a wet environment, sewage carried by dust collection airflow inevitably permeates into the motor under the action of negative pressure, and once water enters the motor through a gap of the shell at the motor, the motor is easy to lose efficacy and damage.

Obviously, the cleaning machine which only can absorb dust but cannot absorb water cannot meet the use requirements of consumers, so that some enterprises develop a floor washing machine which can be used in both dry and wet environments, and particularly, a dust collection barrel part of the floor washing machine is improved to a certain extent, so that dry and wet garbage is well separated, and water and air are prevented from flowing to a negative pressure source.

Although the cleaning machine similar to the above working mode solves the problem of dual purposes of dry and wet, the traditional rolling brush is still adopted to clean the ground on the ground brush part, even if the material of the external accessories of the rolling brush is changed by one part of the cleaning machine aiming at the scene of dual purposes of dry and wet, the cleaning machine can not be well adapted to the ground cleaning requirement under the wet environment, and the cleaning force eliminating effect on stubborn stains is general; patent No. CN201410794982.6 "ground brush device of a dust catcher" just discloses another brush head's concrete form, adopts gear linkage to drive the rotation of brush head, and the rotation gesture of its round brush is distinguished with traditional round brush to realized heavily cleaning to ground, but on the one hand it only uses in the dust catcher, does not optimize the improvement to the wet environment, can not play fine washing effect to subaerial water stain, and on the other hand, its drive division does not have the separation setting with brush head part, still can satisfy the user demand under only having dry environment, but in case entering into the wet environment, the dirt particle that sewage was wrapped in by the clamp stops in each drive part's clearance very easily, leads to the transmission inefficacy. In addition, the transmission form of gear linkage is not beneficial to cleaning the brush head after cleaning, so that after long-term use, partial dust is accumulated too much, and normal use is influenced.
