Description

Dust separation module for cleaning machine and cleaning machine

Technical Field

The utility model belongs to the field of household washing and cleaning, and particularly relates to a dust separation module for a cleaning machine and the cleaning machine.

Background

With the development of household cleaning technology, household cleaning equipment is diversified, and more cleaning equipment is introduced into thousands of households. Traditional dust catcher and sweeper have the design limitation, and its separation module can only separate out solid particle and dust from the negative pressure air current, and this just makes similar equipment only can use under dry environment, once in the wet environment, the water that the negative pressure air current carried can inevitably permeate to the motor department under the effect of negative pressure, once water enters into inside the motor through the gap of motor department casing, leads to the motor to lose efficacy very easily.

Obviously, the cleaner which can only absorb dust but can not absorb water cannot meet the use requirements of consumers, so that some enterprises develop cleaners which can be used in both dry and wet environments, and the dust collecting barrel part of the cleaner is improved to a certain extent, so that dry and wet garbage is well separated.

For example, chinese utility model patent with patent number CN201820710819.0 discloses a "dry and wet dual-purpose hand-held cleaner", its whirlwind water dust separator adopts the multiple-stage separation to filter, when each stage separation filters, the inspiratory water all can be beaten on the deep bead and flow down along with the wind, can not directly be inhaled the air intake of next stage, thereby have very good separation filter effect to water when the dust absorption, the improvement of aqueous vapor separation is carried out on the dirt cup similarly, though avoided the motor to receive the invasion of water to a certain extent, because the most designs of dirt cup of current cleaner on the host computer, need lift up the host computer, dust collecting bucket is whole when handheld, very hard, and receive the limitation in the space, only can allow the dust catcher to absorb a small amount of water, and be not suitable for the sewage circulation when washing ground.

Also, as the chinese patent application No. CN202010568160.1 (publication No. CN111820816A), a "dry and wet dual-purpose sewage tank assembly for a water machine" is disclosed, wherein a sewage inlet pipe is disposed at the bottom of the sewage tank, the filtering assembly is disposed inside the sewage tank and sleeved on the sewage inlet pipe, the tank cover assembly is mounted on the sewage tank, the float assembly is mounted on the lower end surface of the tank cover assembly and disposed in the sewage tank, and the filter hpa is mounted on the upper end surface of the tank cover assembly. Although the design of the sewage tank realizes the dry and wet dual-purpose of the cleaning machine in principle, and has a certain storage capacity for sucked sewage and dust, the sewage tank is very inconvenient because dust is stored in a filter sea handkerchief and needs to be frequently disassembled and cleaned.
