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.

Of course, the lowest position of the protection structure 132 may be higher than the lowest position of the valve assembly 131, and the protection effect of the protection structure 132 is slightly poor.

In the present disclosure, the protective structure 132 is disposed on the host portion 140, so that the joint assembly 130 is disposed on the host portion 140.

In one implementation, the guide ramp slopes downwardly in a front-to-rear direction when the surface cleaning apparatus 100 is in an upright position.

An accommodating space is formed inside the protective structure 132, and the valve assembly 131 is disposed in the accommodating space of the protective structure 132; and a chamber is formed between the guard structure 132 and the valve assembly 131, the chamber communicating with the cleaning liquid storage part 110.

Preferably, the lower end of the guiding rib 1321 is formed as a wedge structure, and the wedge structure of the guiding rib 1321 is formed as a guiding structure of the connection interface 220, that is, the wedge structure of the guiding rib 1321 is used for guiding the connection interface 220 when the connection interface 220 is mounted on the joint assembly.

On the other hand, at least one guiding groove 1322 is formed on the inner wall surface of the protective structure 132, and the guiding groove 1322 is matched with the guiding part 221 of the connection interface 220 of the base station 200 to limit the rotation of the protective structure 132 relative to the connection interface 220, so that the rotation of the surface cleaning equipment relative to the base station is limited, and the forward tilting of the surface cleaning equipment relative to the base station is also limited, so that the surface cleaning equipment is more stable when being placed on the base station.

The number of the guide grooves 1322 is at least two, wherein two of the guide grooves 1322 are provided to the opposite inner wall surfaces of the shielding structure 132.

In an alternative embodiment of the present disclosure, the guide groove 1322 may be formed by two adjacent guide ribs 1321, i.e., a portion in the middle of two guide ribs 1321.

To facilitate guiding the guiding portion 221 of the connection interface 220 to the guiding groove 1322, on one hand, the width of the guiding groove 1322 is gradually reduced from bottom to top; that is, the lower portion of the guide recess 1322 is large in size and has a horn shape which is opened downward as a whole; on the other hand, the lower ends of the two guide beads 1321 forming the guide groove 1322 are formed in a wedge structure, and the distance between the wedge structures of the two guide beads 1321 is made greater than the width of the lower end of the guide groove 1322, so that the lower end of the guide bead 1321 is formed as a guide structure of the guide part 221 of the connection port 220.

According to at least one embodiment of the present disclosure, a surface of the at least one guiding rib 1321 contacting the connection interface 220 of the base station 200 is formed in a curved surface shape, and a surface of the guiding rib 1321 contacting the connection interface 220 of the base station 200 is matched with a surface of the connection interface 220, so that the guiding rib 1321 is tightly matched with an outer wall surface of the connection interface 220, and a technical effect of preventing rotation between the connector assembly and the connection interface 220 can be achieved.

Optionally, a gap of less than 0.2mm is formed between the guiding rib 1321 and the outer wall surface of the connection interface 220, so that the guiding rib 1321 and the connection interface 220 are tightly fitted.

In the present disclosure, a portion of the main body part 140 adjacent to the joint assembly 130 is formed in a slope structure, and the slope structure is inclined upward in a front-to-rear direction, so that the surface cleaning apparatus can be guided by the slope structure when the surface cleaning apparatus is installed to the base station.

In an optional embodiment of the disclosure, the surface cleaning apparatus further comprises a charging coupling structure located at the rear of the surface cleaning apparatus and above the joint assembly.

Fig. 5 is a schematic structural diagram of a connection interface according to one embodiment of the present disclosure.

According to another aspect of the present disclosure, as shown in fig. 1 and 5, there is provided a base station 200, including:

a cleaning liquid supply part 210, the cleaning liquid supply part 210 storing a cleaning liquid; and

a connection interface 220, the connection interface 220 being connected to the cleaning liquid supply 210, the connector assembly 130 of the surface cleaning apparatus 100 being connected to the connection interface 220 to deliver cleaning liquid from the cleaning liquid supply 210 to the cleaning liquid storage 110 via the connection interface 220 or to deliver cleaning liquid in the cleaning liquid storage 110 to the cleaning liquid supply 210 via the connection interface 220 when the surface cleaning apparatus 100 is docked to the base station 200;

wherein the connection interface 220 comprises at least one guide portion 221, wherein the guide portion 221 is engaged with the guide groove 1322 of the connection interface 220 when the connection interface 220 is connected with the connector assembly 130 of the surface cleaning apparatus 100.

The number of the guide parts 221 is the same as that of the guide grooves 1322 or less than that of the guide grooves 1322, so that the guide parts 221 are disposed at least partially in the guide grooves 1322.

At least some of the guiding portions 221 are located on the opposite outer side walls of the connection interface 220, for example, when the number of the guiding portions 221 is two, the two guiding portions 221 are respectively located on the side walls of the connection interface in the left-right direction, which is the direction corresponding to the front-back direction of the connection interface.

Preferably, the upper end of the guide part 221 is formed in a tapered structure, for example, a pyramid-type structure or a frustum-type structure by a plurality of slopes, so that the upper end of the guide part 211 can be smoothly inserted into the guide groove 1322.

In the present disclosure, the connection interface 220 includes a position-limiting portion 222, wherein the connection interface 220 is guided to the inside of the joint assembly by the contact of the position-limiting portion 222 with the valve assembly, so that a stable connection is formed between the connection interface and the joint assembly.
