Description

Sewage tank for cleaning machine and cleaning machine

Technical Field

The utility model relates to the field of household cleaning, in particular to a movable cleaning device, and especially relates to a sewage tank for a cleaning machine and the cleaning machine.

Background

With the development of household cleaning technology, household cleaning devices are gradually diversified, and more cleaning devices enter thousands of households. The existing cleaning equipment can be generally used in dry and wet use scenes, taking a floor cleaning machine as an example, in order to collect sewage and sundries, the existing floor cleaning machine is generally provided with a sewage tank, the sewage and sundries collected by a floor brush module are conveyed and collected in the sewage tank through a pipeline under the negative pressure effect of a fan module for temporary storage, and after the cleaning work is finished, the sewage tank is directly poured and the inner space of the sewage tank is cleaned.

Due to the use characteristics of the floor scrubber in dry and wet scenes, the sewage tank structure of the floor scrubber needs certain waterproof sealing performance so as to prevent moisture from invading into a downstream fan module and further avoid damage of a fan motor. When the conventional cleaning machine is used, the machine body of the conventional cleaning machine is usually slightly inclined with the vertical direction, namely basically kept in an upright posture, so that the water and gas can not enter the blower along with the air flow only by arranging a certain seal at the position of the air outlet at the top of the sewage tank. However, under some special use scenes, the floor washing machine needs to be put down and dragged to clean some sanitary dead angles, for example, if the bottom of a bed or a wardrobe is cleaned, the floor washing machine needs to be put down for use, under such use scenes, the upper end and the lower end of the sewage tank in the vertical posture are basically positioned on the same horizontal plane, sewage collected in the sewage tank can continuously flow to the air outlet end of the sewage tank, the original sealing grade of the air outlet end of the sewage tank is not high enough to realize sealing under the use environments, and therefore, if the sewage tank is not improved, the risk of damage of a fan is greatly improved.

For this reason, chinese patent application No. cn202111556444.X (publication No. CN114190850 a) discloses a "sewage tank and scrubber", in which the sealing of the entire sewage tank to sewage is still dependent on the sealing strip at the upper end of the sewage tank, though the solid-liquid separation efficiency is increased by providing a volute member in the tank body; in another example, in the chinese patent No. CN202220933931.7, an intelligent floor washer for preventing sewage from flowing backward is disclosed, in the floor washer, a partition plate is disposed in a sewage tank, and when a straight pipe passes through the partition plate and reaches the upper side of the partition plate, and an installation rod is horizontally placed, sewage is blocked by the partition plate, and only a drain pipe leading to the upper side of the partition plate is blocked by an elastic mechanism matched with a blocking block, so that the sewage can be prevented from entering a vacuum pump.
