Fig. 8 is a schematic cross-sectional view of the nozzle assembly of fig. 6 taken in a horizontal direction. The embodiment shown in fig. 1 discloses a surface cleaning apparatus 100 comprising a main body 1, a cleaning head 2 and a cleaning liquid supply system. The main body 1 is pivotally connected to the cleaner head 2. The cleaning head 2 is used to clean a surface to be cleaned. The cleaning liquid supply system is used for supplying cleaning liquid to the surface to be cleaned. The cleaning liquid supply system includes a steam generator, a delivery line, a nozzle assembly, and a controller. The steam generator is used for generating steam after heating water. The delivery line is in fluid communication with the steam generator for delivering steam generated by the steam generator. Referring to fig. 3-5, a nozzle assembly 3 is provided in the cleaning head 2 in fluid communication with the delivery conduit for spraying steam onto the surface to be cleaned, the nozzle assembly 3 comprising a first nozzle structure 33 and a second nozzle structure 34 connected in parallel with each other. The first nozzle structure 33 includes a steam line and a first nozzle 331 communicating with the steam line. The second nozzle structure 34 includes a steam line and a second nozzle 332 in communication with the steam line. The controller is configured to control one of the first nozzle arrangement 33 and the second nozzle arrangement 34 to spray steam towards the surface to be cleaned. In one embodiment, the temperature of the steam ejected by the first nozzle structure 33 and the second nozzle structure 3 is different, e.g. the temperature of the steam ejected by the first nozzle structure 33 is higher than the temperature of the steam ejected by the second nozzle structure 34. The temperature of the steam may be adjusted by controlling the steam generator by the controller. Of course, in other embodiments, two steam generators may be further included, each steam generator corresponds to one nozzle structure, and when the controller is required to control one of the nozzle structures to operate, the corresponding steam generator operates, and the other steam generator does not operate. In another embodiment, the first and second nozzle structures may emit steam at the same temperature but different amounts or at different positions, and specifically, the first nozzle structure 33 may emit steam uniformly toward the surface to be cleaned, and the second nozzle structure 34 may emit steam toward a specific position. In other embodiments, the injection positions, the injection amounts, and the steam temperatures of the first nozzle structure 33 and the second nozzle structure 34 may be different or may be different from one or both of the three, and are not limited in detail herein. Adopt two steam nozzle assembly 3, can adapt to different scenes, improve the convenience. As in the embodiment shown in fig. 6-8, the first nozzle structure 33 and the second nozzle structure 34 are integrally formed. Two independent grooves are limited in an integrally formed structure, and through holes are formed in the grooves and are air injection ports. The two grooves can be arranged up and down and also can be arranged front and back. In other embodiments, the first nozzle structure 33 and the second nozzle structure 34 may also be provided separately.

Referring to fig. 3 to 5, the cleaning head 2 is further provided with a roller brush 21 rotatable along its axis, and a first nozzle structure 33 and a second nozzle structure 34 are provided in front of the roller brush 21 in the advancing direction of the cleaning head 2. After the dirt on the surface to be cleaned is pretreated by the high-temperature steam, the dirt is scraped by the rolling brush 21 rotating at a high speed, and compared with scraping pieces such as rags, the cleaning effect is more obvious.

Referring to fig. 3 to 5, the first nozzle structure 33 includes a plurality of first nozzles 331 uniformly arranged in the axial direction of the roll brush 21. The second nozzle structure 34 includes a single second nozzle 332 provided at an intermediate position of the second nozzle structure 34 in the axial direction of the roll brush 21. The nozzles of the second nozzle structure 34 are configured to spray steam diagonally forward. The second nozzle structure 34 is centrally located to provide more user control of the position.

With continued reference to figure 5, in order to better achieve spot spraying whilst allowing the user to more intuitively see the spray location, the second nozzle arrangement 34 is disposed forwardly of the first nozzle arrangement 33 in the forward direction of the cleaner head 2.

In other embodiments, the second nozzle structure 34 is disposed above or below the first nozzle structure 33 in the vertical direction. Therefore, the distance between the rolling brush 21 and the wall surface can be effectively reduced in the cleaning process, so that the rolling brush 21 is close to the wall surface as much as possible, and gaps close to the wall surface are cleaned as much as possible.

The spray of the first nozzle arrangement 33 is arranged to spray steam directly below (substantially directly against) the surface to be cleaned, relatively close to the roller brush 21, so that the floor can be treated by the roller brush 21 at a first time after the steam has reached the floor.

Referring to fig. 4, in the embodiment shown in the drawings, the delivery lines include a control valve 37, a first line 35 communicating the control valve 37 with the first nozzle arrangement 33, and a second line 36 communicating the control valve 37 with the second nozzle arrangement 34. The first and

second conduits

35, 36 are disposed on the same side of the cleaner head 2. The two pipelines are arranged on the same side, so that the assembly is convenient, and the temperature emitted by the pipelines has the smallest influence on other structures, such as a motor, a transmission mechanism and the like.

While the embodiments of the invention have been described above, it is not intended to be limited to the embodiments shown, and described, but rather to be accorded the widest scope consistent with the principles and novel features herein disclosed, and to such extent as may be readily modified by those skilled in the art, and to such extent as is not limited by the specific details shown and described herein without departing from the general concepts defined by the claims and their equivalents.
