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

The existing cleaning equipment can be generally used in dry and wet use scenes, taking a floor cleaning machine as an example, and because the floor cleaning machine has the use characteristics in the dry and wet use scenes, the sewage tank structure of the floor cleaning equipment 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.

Therefore, the Chinese patent of patent No. CN202220933931.7 discloses an intelligent floor washer for preventing sewage from flowing backward, in the floor washer, a baffle is arranged in a sewage bucket, a straight pipe penetrates through the baffle to reach the upper side of the baffle, when an installation rod is horizontally placed, sewage is blocked by the baffle, and only a drain pipe leading to the upper side of the baffle is sealed by an elastic mechanism matched with a sealing block, so that the sewage can be prevented from entering a vacuum pump. Although the floor washing machine can be used for leveling, the fixed partition board designed in the box body not only makes sundries difficult to clean, but also is unfavorable for solid-liquid separation in the sewage box; therefore, the Chinese patent with the patent number of CN202123195420.4 discloses a sewage collecting tank and cleaning equipment, and through a specially designed water baffle, the water baffle can be synchronously disassembled along with the upper shell after being assembled on the upper shell, so that the sewage in the sewage tank can be conveniently cleaned, and the bowl design of the water baffle can also change the movement direction of the sewage, so that the solid-liquid separation is facilitated.

Although the design of adding the water baffle achieves better separation effect, the bowl-shaped design of the water baffle can also increase accumulation of dirt due to a gap left between the edge and the dirt inlet pipe, so that risks of sundries being blocked at the gap when the sundries are collected to the sewage tank are greatly increased, and fluid is radially discharged from the bowl-shaped outer edge, so that air flow is wrapped with liquid, and the water prevention of a downstream fan module is not facilitated.
