Description

Pumping structure for base station and base station

Technical Field

The present disclosure relates to a pumping structure for a base station and a base station.

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.

The cleaning effect of the hot water is remarkably effective. Therefore, cleaning by heating water can be considered. However, in view of endurance and water-holding issues, this energy loss may be transferred to the base station in order to reduce the energy loss of the surface cleaning apparatus itself. Therefore, a water replenishing base station (base station) is arranged, a water storage tank is arranged on the base station, water in the water storage tank is heated, and the water is heated to a temperature suitable for cleaning stubborn stains and is kept.

However, when the temperature of the cleaning liquid within the surface cleaning apparatus is low and cleaning of the surface to be cleaned is poor, it is necessary to increase the temperature of the cleaning liquid within the surface cleaning apparatus by fluid interaction of the surface cleaning apparatus with the base station.

Therefore, a pumping structure for a base station and a base station are needed to solve the above technical problems.
