Fig. 14 is a schematic sectional view taken along a-a direction in fig. 3. Fig. 15 is a schematic structural diagram of a tray in an embodiment. Fig. 16 is an enlarged schematic view of region F in fig. 15. FIG. 17 is a top view of a tray in an embodiment. The direction of the arrows in the figure is the direction of the air drying air flow. Referring to fig. 3, 4 and 15, the base 2 includes a housing having a tray 23 disposed thereon, the tray 23 being integrally formed with the housing and being detachably connected to facilitate individual cleaning of the tray 23. The tray 23 defines a cleaning groove for cleaning the drum brush 12, and the tray 23 is provided with water leakage holes 231, the water leakage holes 231 being provided at corners of the tray 23 near the cleaning groove. In one embodiment, the tray 23 is provided with a plurality of water leakage holes 231 at both corners thereof to guide the liquid out of the tray 23 at the first time after the water in the cleaning tank overflows, and the bottom of the tray 23 is provided with an opening through which the liquid overflowing from the tray 23 can flow toward the placement surface from the tray 23.

Referring to fig. 15 to 17, the water leakage hole 231 is provided with a baffle 232 at a position adjacent to the nozzle 13. The baffle 232 functions to prevent the liquid sprayed from the nozzle 13 from directly flowing out of the water leakage hole 231 during the self-cleaning process. Two baffles 232 are shown in fig. 15, and the middle area of the two baffles 232 facing the nozzle 13 (see fig. 2) of the surface cleaning apparatus can effectively prevent water sprayed from the nozzle 13 from directly entering the water leakage hole 231.

In other embodiments, the baffle 232 may not be disposed around the water leakage hole 231, but the water leakage hole 231 is located in a region slightly higher than the region corresponding to the nozzle 13 to prevent the liquid sprayed from the nozzle 13 from directly flowing out of the water leakage hole 231.

In the embodiment shown in figure 1, the surface cleaning apparatus 1 is a wired cleaning apparatus which, in use, needs to be connected to a municipal power supply by means of a wire, in order to be usable. Specifically, the surface cleaning equipment can generate steam, and the surface to be cleaned is cleaned through the steam, so that the cleaning effect is effectively improved. When the cleaning device is docked to the base 2, the steam nozzle 13 is located just in the middle of the two baffles 232, and the highest point of the baffles 232 can contact the cleaning head 11 to achieve a sealing effect.

Referring to fig. 4 to 17, the base 2 includes a housing, which may be composed of an upper housing 21 and a lower housing 22, and a guide duct 24, between which an installation space is defined between the upper housing 21 and the lower housing 22. The upper housing 21 defines an accommodating space 26, the accommodating space 26 being for accommodating at least part of the cleaning head 11 of the surface cleaning apparatus. The cleaning head 11 may be self-cleaning when docked to the receiving space 26. The self-cleaning process is performed by spraying a cleaning liquid, which may be water or steam, into the receiving space 26 by the cleaning liquid supply system, and spraying the cleaning liquid onto the housing and the rolling brush 12 by the spray nozzles 13. The scraping strips around the roller brush 12 scrape off the dirt on the roller brush 12, so that the roller brush 12 can clean and the dirt recovery system of the cleaning device recovers the dirt in the accommodating space 26. The soil recovery system may include a suction motor and also recover soil entirely by the rotation of the drum brush 12. The base 2 is further provided with a guide air duct 24, at least a part of the guide air duct 24 is disposed in the housing, and the guide air duct 24 is used for guiding the air flow generated by the fan 25 to the accommodating space 26. The fan 25 may be a fan 25 separately mounted to the base 2 or may be a fan 25 of a dirt recovery system on the cleaning appliance. In this embodiment, the air guide duct 24 may be formed by mounting the upper cover 255 and the lower cover 256 together. A separate fan 25 is provided in the installation space of the housing together with the guide duct 24. The wind generated by the fan 25 is guided into the accommodating space 26, particularly near the cleaning tank, through the guide duct 24 to dry the roll brush 12. Further, in order to improve the air drying effect, a heater 27 is added in the guide air duct 24 to heat the air drying airflow, so as to improve the air drying effect.

In one embodiment, the air outlet 254 of the air guiding duct 24 may be provided with a shielding mechanism (not shown), the shielding mechanism may shield the air outlet 254 to prevent steam from entering when the fan 25 does not operate, and the shielding mechanism may be blown away by the airflow and may be driven to open by the driving mechanism when the fan 25 operates.

Referring to fig. 6-14, in a self-cleaning or other situation, liquid may enter the guide duct 24 from the air outlet 254 and damage the fan 25 or the heater 27. In order to prevent this, at least one liquid outlet hole 241 for discharging the liquid in the guide air duct 24 is disposed in the guide air duct 24. The liquid outlet 241 can discharge the liquid out of the guiding air duct 24 at the first time. To reduce the air flow in the guiding air duct 24 from exiting the liquid outlet hole 241, a guiding structure 242 may be disposed around the liquid outlet hole 241, and the guiding structure 242 is configured to guide the air flow in the guiding air duct 24 to pass through the liquid outlet hole 241. Generally, the flow guiding structure 242 is disposed upstream of the liquid outlet 241 in the flowing direction of the air flow, so as to reduce the air flow flowing out from the liquid outlet 241 as much as possible. Further, the flow guiding structure 242 may be arranged above the exit opening 241.

Referring to fig. 8 to 13, in order to ensure that the liquid flows out in the first time, liquid outlet holes 241 are disposed at the bottom of the air guide duct 24 along the height direction of the air guide duct 24. Further, the guide air duct 24 includes a horizontal section 243 and a lifting section 244, and the liquid outlet 241 is disposed at the intersection of the horizontal section 243 and the lifting section 244. The liquid outlet 241 may be a long strip-shaped opening perpendicular to the direction of the air flow, or may be a plurality of unconnected holes.

Referring to fig. 12 and 13, the lifting section 244 includes a rising portion 245, a horizontal portion 246, and a falling portion 247 which are sequentially conducted, and the air outlet 254 of the falling portion 247 is lower than the horizontal portion 246. Even if a small amount of liquid enters the air outlet 254, the liquid does not immediately enter other positions of the air guide duct 24, and only accumulates or flows into the accommodating space 26 again.

Referring to fig. 14, a heater 27 is provided in the guide duct 24, and a lowest end of the heater 27 is higher than a lowest end of the guide duct 24. Further, the lowest end of the heater 27 is higher than the liquid outlet 241, so that the heater 27 can be prevented from being damaged due to the fact that the liquid cannot be discharged timely when the amount of the liquid is large.

Referring to fig. 6, a guide plate 248 is disposed between the heater 27 and the air outlet 254 of the guide duct 24 in the flow direction of the air flow. The guide plate 248 can guide the air flow to flow more smoothly, and avoid generating turbulent flow and influencing the air outlet effect.

Referring to fig. 8 and 9, the guide duct 24 includes a bottom wall 249 and a top wall 251 disposed opposite to each other, and a side wall extending between the bottom wall 249 and the top wall 251, the bottom wall 249 includes a horizontal wall 252 and a lifting wall 253, and a liquid outlet 241 is formed between the horizontal wall 252 and the lifting wall 253. The end of the horizontal wall 252 is raised upwardly to form the flow directing structure 242. In particular, referring to the figures, in this embodiment the flow guiding structure 242 is inclined upwards with respect to the bottom wall 249 to ensure that the air flow may skip the exit opening 241. By adopting the structure, when the air flow skips the liquid outlet 241, because the air flow flows obliquely upwards relative to the liquid outlet 241, a small vortex can be formed in the area of the liquid outlet, and the small vortex can accelerate the liquid to move towards the liquid outlet, thereby avoiding the air flow carrying the roll to be blown onto the rolling brush 12 again. Further, the flow guiding structure 242 faces the lifting wall 253, so that the air flow guided by the flow guiding structure 242 can be prevented from colliding with the top wall 251, which causes energy loss and generates turbulence.

FIG. 18 is a schematic structural diagram of a base in another embodiment. Referring to fig. 17, in another embodiment, a gap 233 is provided in front of the detachable tray 23 to avoid the air outlet 254 of the air guide duct 24, the gap 233 is matched with the air outlet 254 of the air guide duct 24, and the gap 233 is convenient for a user to pour out the water in the tray 23 when cleaning the tray 23. The water leakage holes 231 are provided at both sides of the notch 233, and the baffle 232 is provided between the water leakage holes 231 and the notch 233.

The following describes the self-cleaning-seasoning operation of the cleaning system shown in FIG. 1:

the base 2 is provided with a first sensing element for determining whether the surface cleaning apparatus is docked to the base 2. The first sensing element may be a magnet, or may be other sensing elements, such as a mechanical sensing element and a photoelectric sensing element, which are not described in detail herein, and when the cleaning device is placed on the base 2, the sensing element on the cleaning device cooperates with the first sensing element on the base 2 to send a signal, and when the signal is received by the controller of the cleaning device, the self-cleaning program is started, and when the cleaning device is not placed on the base 2, the controller of the cleaning device cannot start the self-cleaning program. In this embodiment, the cleaning device is connected to a municipal power supply to perform self-cleaning.

Further, a second sensing element for detecting the rotation speed of the roll brush 12 is provided on the base 2. Specifically, the second sensing element may be a hall sensor for sensing the rotation speed of a transmission gear for driving the roll brush 12 to rotate. In this way, the rotational speed of the roll brush 12 can be sensed by the hall sensor. The base 2 further comprises a controller for controlling the operation of the fan 25 in dependence on the rotational speed of the floor brush. The controller receives or acquires signals sent by the Hall sensor. When the rolling brush 12 is self-cleaning, the rolling brush 12 rotates at a relatively high speed, and the fan 25 and the heater 27 are not operated. After the rolling brush 12 is automatically cleaned, the rolling brush 12 rotates slowly, and at this time, the controller of the base 2 determines that the rolling brush 12 needs to be air-dried according to a signal sent by the hall sensor, so that the controller controls the fan 25 to start to deliver air flow to the rolling brush 12. Further, the heater 27 is controlled to operate at the same time as the blower 25 is started. Hot air is blown to the rolling brush 12 to reduce the air drying time.

While embodiments of the utility model have been described above, it is not limited to the applications set forth in the description and the embodiments, which are fully applicable in various fields of endeavor to which the utility model pertains, and further modifications may readily be made by those skilled in the art, it being understood that the utility model is not limited to the details shown and described herein without departing from the general concept defined by the appended claims and their equivalents.
