Description

Surface cleaning apparatus and surface cleaning system

Technical Field

The present disclosure relates to a surface cleaning apparatus and a surface cleaning system.

Background

Today's surface cleaning devices are used for wet cleaning hard floors or short-hair carpets. The device typically has one or more rolling brushes or cleaning discs made of a wool material which can scrub tough soils on the floor by adding water or a water/cleaner mixture.

When the machine moves over the dirt, the dirt that has been wiped off by the roller brush and dissolved by the water or water/detergent mixture is sucked up with the cleaning head arranged in the direction of movement of the roller brush, and in the technique of providing the cleaning tray, the cleaning head may not be provided and the dirt is directly adsorbed by the cleaning material on the cleaning tray.

However, stubborn stains are generally difficult to clean, and milk stains, fruit juices, sauces and the like are scattered on the floor surface, and after water is evaporated, stubborn stains which are difficult to remove are formed on the cleaning surface. Often, not all of this stubborn dirt is removed by vacuuming during scrubbing, and some of it remains on the floor, reducing the quality of the cleaning.

In order to improve the cleaning quality, cleaning is usually performed by mixing a cleaning agent and water, the cleaning agent and the water are mixed in a clean water tank of the surface cleaning device according to a certain proportion to form a cleaning fluid, and then the cleaning fluid is applied to a rolling brush or a cleaning disc to achieve a good cleaning effect of stubborn stains. This means, however, that the proportion of cleaning agent is controlled, the cleaning process of the cleaning agent must also be carried out exclusively, and it is not necessary to apply such cleaning agent everywhere on the cleaning surface in order to achieve optimum cleaning quality and hygiene, which leads to increased expenditure of time and additional costs.

The other mode is to implement steam treatment, a hot steam generating device is arranged in the surface cleaning device, when a specific stubborn stain surface is cleaned, through input of a control signal, an atomizing heating device of the surface cleaning device carries out steam treatment on water in a clean water tank, and the water is sprayed to a rolling brush or a cleaning disc, particularly a cleaning surface, so as to soften the stubborn stain and enable the stubborn stain to be separated from the surface, and the cleaning purpose is achieved.

The existing surface cleaning device, no matter an autonomous mobile cleaning device or a handheld cleaning device, is limited in volume of a clean water tank carried by the device due to natural limitations of the structure and the volume, needs to frequently replace clean water when cleaning a large area, particularly when the large area is stained, has short endurance, brings about reduction in experience, and accordingly, the water storage tank is gradually set on a base station.

However, when the water storage tank is arranged in the base station, because the base station is provided with the water receiving port and the charging structure at the same time to charge and replenish water for the surface cleaning equipment, when the surface cleaning equipment is placed in the base station or taken down from the base station, the interference between the cleaning liquid of the water receiving port and the charging structure is not desired, that is, the cleaning liquid near the charging structure is not desired; when surface cleaning device and basic station butt joint, because the mouth of a river of surface cleaning device is misaligned with the water receiving mouth of basic station, on the one hand can't realize the butt joint smoothly, on the other hand also can produce impact damage to surface cleaning device and basic station.

There is therefore a need for a technique that solves the above problems.
