In the present embodiment, "front", "rear", "left", "right", "up" and "down" respectively correspond to the positional relationships of the surface cleaning head shown in fig. 1, and the "vacuum cleaner" in the present embodiment may be an upright cleaner, a handheld cleaner, or other cleaner using the vacuum cleaning principle.

As shown in fig. 1, the surface cleaning head of the present case includes a cleaning head body 1 and a wet type floor mopping device 2.

As shown in fig. 2, the cleaner head body 1 includes a cleaner head housing 11, a rotary joint 12 installed at the rear of the cleaner head housing 11, and a pair of rear wheels 13 installed at the rear of the cleaner head housing 11 for supporting the cleaner head housing 11 on the floor to be cleaned, and a dust suction opening 111 is provided at the bottom of the cleaner head housing 11. The rotary joint 12 includes a first rotary joint 121 hinged at the rear of the cleaning head housing 11, and a second rotary joint 122 hinged with the first rotary joint 121. The first rotary joint 121 can rotate around an X axis in the front-rear direction, and the second rotary joint 122 can rotate around a Y axis in the left-right direction.

As shown in fig. 3, the wet type floor mopping device 2 includes a mop base 21 and a water service box 22 fixed to an upper side of the mop base 21. The lower portion of the mop base 21 is used for installing a mop, and the mop base 21 is provided with a water outlet hole communicated with the water service box 22, and the water service box 22 can supply water to the mop base 21 to wet the mop. The mop base plate 21 is provided with a pair of notches 211, the mop base plate 21 is provided with a connecting part 212 between the two notches 211, the connecting part 212 is provided with a pair of positioning pins 213, and with reference to fig. 4, the cleaning head housing 11 is provided with a pair of positioning holes 112 matched with the pair of positioning pins 213, so that the mop base plate 21 can be detachably mounted on the cleaning head housing 11 in an inserting manner. In other embodiments, in order to detachably mount the wet type mopping device 2 on the cleaning head body 1, the matching mode between the mop cloth base plate 21 and the cleaning head shell 11 can also be a magnetic attraction mode, i.e. the mop cloth base plate 21 and the cleaning head shell 11 are respectively provided with a matched magnetic piece; in addition, the engaging means between the mop base 21 and the cleaning head housing 11 may be a snap-fit type or a hook-and-loop type, such as engaging latch, engaging groove, etc. Referring to fig. 1, when the wet type floor mopping device 2 is installed on the cleaning head body 1, the pair of rear wheels 13 are located at the pair of notches 211 of the mop cloth base plate 21, and the dust suction opening 111 at the bottom of the cleaning head housing 11 is closely attached to the floor to be cleaned, so that the dust suction effect is better. The connection portion 212 is located below the rotary coupling head 12, so that the cooperation between the cleaner head body 1 and the wet type floor mopping device 2 is more compact and occupies no space. In this example, the mop shape may be regular, for example square, when the mop is attached, either all of which are located directly behind the rear wheel or part of which extends to the outer periphery of the rear wheel, similar to the shape of the mop base. After the mop cloth is installed at the lower portion of the mop cloth base plate 21, the pair of rear wheels 13 and the mop cloth are supported on the floor to be cleaned, and when a user pushes the surface cleaning head to perform a floor mopping operation while sucking dust on the floor to be cleaned, the mop cloth is positioned right behind the rear wheels 13, and a cleaning area of the mop cloth covers a moving path of the rear wheels 13, so that moving traces left on the floor to be cleaned by the rear wheels 13 can be wiped.

As shown in fig. 2, 5 and 6, the surface cleaning head further comprises a locking mechanism 4 for locking the wet floor device 2 to the cleaning head body 1, an unlocking member 5 provided on the mop base 21 and operated by a user to unlock the locking mechanism 4, the locking mechanism 4 being partially located on the cleaning head housing 11 and partially located on the mop base 21.

Specifically, referring to fig. 7 and 8, the locking mechanism 4 includes a latch 41 movably disposed on the mop base plate 21, a return spring 42 disposed on the mop base plate 21 and in abutting contact with a rear end of the latch 41, and a locking groove 43 disposed on the cleaning head housing 11, wherein a front end of the latch 41 is provided with a locking hook 411 engaged with the locking groove 43, in this example, the unlocking member 5 is a pedal, one end of the pedal is hinged to the mop base plate 21, and the other end of the pedal is in transmission with the latch 41, so that the pedal can push the latch 41 to the rear side to disengage the locking hook 411 from the locking groove 43.

As shown in fig. 9 and 10, when the wet type floor mopping device 2 is assembled to the cleaning head body 1, in order to make the mop cloth at the lower part of the mop cloth base plate 21 closely fit to the floor to be cleaned and improve the mopping effect of the surface cleaning head 1, the surface cleaning head 1 further comprises a pressing mechanism 3 for pressing the mop cloth base plate 21 against the floor to be cleaned, wherein the pressing mechanism 3 is partially positioned on the rotary connector 12 and partially positioned on the mop cloth base plate 21.

Specifically, the pressing mechanism 3 includes a pressing rod 31 fixed on the first rotating joint 121, and an elastic support member 32 supported between the pressing rod 31 and the mop base plate 21. In this example, the resilient support 32 is a compression spring. In other embodiments, the pressing mechanism 3 may also be a pressing rod and a pressing block, which are press-fit with each other, that is, by providing a pressing rod on the rotating connector and a pressing block on the mop base plate, which is fit with the pressing rod, the pressing of the mop base plate on the ground to be cleaned is achieved by pressing the pressing rod on the pressing block.

Thus, when the user pushes the surface cleaning head 1 to clean the floor while sucking dust, the included angle between the first rotating joint 121 and the floor to be cleaned can be reduced by operating the push rod and other parts (not shown in the figure), so that the compression rod 31 can tightly support the compression spring and transmit the external force to the mop cloth substrate 21, and finally the mop cloth substrate 21 is pressed on the floor to be cleaned, thereby improving the mopping and washing effect of the surface cleaning head. In order to ensure the air intake of the dust suction port 111, at least a part of the connecting part 212 is located below the cleaning head housing 11, so that a gap of 1-3 mm is formed between the lower surface of the cleaning head housing 11 and the floor to be cleaned.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
