[0037] To describe the technical solutions of the embodiments of the present application in detail, the technical solutions of the embodiments of the present application will be described below with reference to the drawings of the embodiments of the present application.

[0038] In the present application, spatial relative terms such as "below", "lower", "under", "underneath", "below", "above", "upper", "higher", "side" (for example, as in "sidewall") are used herein for ease of description to describe one element's or feature's relationship to another element(s) or feature(s) as illustrated in the figures. The spatial relative terms are intended to encompass different orientations of the device in use, operation and / or manufacture in addition to the orientations depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "under" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. Moreover, the device can be otherwise oriented (for example, rotated 90 degrees or at other orientations) and the spatial relative terms used herein interpreted accordingly.

[0039] Figure 1 A surface cleaning system 100 provided by the present application is shown, which comprises a surface cleaning device 10 and a base station 20 independent of the surface cleaning device 10. The surface cleaning device 10 can move along a surface to be cleaned and perform a cleaning operation, and the base station 20 can be used to place the surface cleaning device 10 and clean a cleaning component 14 (see below) of the surface cleaning device 10.

[0040] Referring to Figures 2-3 The surface cleaning device 10 comprises a cleaning base 1 that can move along a surface to be cleaned, and a standing body 2 rotatably connected to a rear portion of the cleaning base 1.

[0041] The cleaning base 1 comprises a seat body 11 forming an outer contour of the main body, an upper cover 12 detachably connected to a front portion of the seat body 11, a cleaning component 14 rotatably mounted on the seat body 11, a side brush 15 in driving connection with the cleaning component 14, and a suction nozzle 16 located inside the seat body 11.

[0042] The seat body 11 and the upper cover 12 jointly define a rotating body cavity 13 located at a front portion of the cleaning base 1, and the rotating body cavity 13 has a lower opening 131 facing the surface to be cleaned. The cleaning component 14 provided in the present embodiment is a brush roll, and the cleaning component 14 is rotatably arranged at the rotating body cavity 13 and a part of an outer peripheral surface of the cleaning component 14 passes through the lower opening 131 to contact the surface to be cleaned.

[0043] In combination withFigure 4 The cleaning member 14 comprises a roller body 142 having a cavity 141 inside and a bristle layer 143 covering the outer circumferential surface of the roller body 142. The roller body 142 comprises a first end and a second end which are distanced from each other and a plurality of through holes (not shown) on the outer circumferential surface. Each of the through holes is in fluid communication with the cavity 141 and provides a first fluid passage (see below) for applying cleaning liquid to the bristle layer 143. Since the through holes are located at the roots of the bristle layer 143, the cleaning liquid and air flow can reach the roots of the bristle layer 143 when the cleaning member 14 is cleaned and dried by the through holes (see below), thus achieving a better cleaning effect.

[0044] The cleaning base 1 further comprises a driving motor (not shown) inside the seat body 11 and a quick release member 17 for supporting the side brush 15. The first end of the roller body 142 is drivingly connected to the driving motor, so that the driving motor can drive the cleaning member 14 to rotate.

[0045] The quick release member 17 is detachably mounted on the front of the seat body 11 and located at the rotating body cavity 13. The quick release member 17 comprises a main body 171 detachably connected to the seat body 11, a rotating member 172 rotatably arranged on the side of the main body 171 and facing the cleaning member 14, and a hollow pin shaft 173.

[0046] The second end of the roller body 142 is fixedly mounted on the rotating member 172 of the quick release member 17. The main body 171 defines a semi-enclosed chamber 174 and is provided with left and right through connecting ports (not shown). The pin shaft 173 is arranged at the connecting ports and fixedly arranged on the rotating member 172. It can be understood that the cleaning member 14, the rotating member 172 and the pin shaft 173 rotate synchronously.

[0047] The side brush 15 is arranged in the chamber 174 of the main body 171 and comprises a brush body (not shown) and a plurality of bristle tufts (not shown) fixedly connected to the brush body. The brush body is fixedly supported on the pin shaft 173 of the quick release member 17 and rotates with the pin shaft 173. The plurality of bristle tufts can radially and / or laterally extend outward from the chamber 174 to clean the contacted surface to be cleaned. It can be understood that the side brush 15 is particularly suitable for cleaning corners of walls, tables and the like.

[0048] In combination Figure 8The pin shaft 173 is exposed from the middle of the cleaning component 14 and forms an external interface (not shown in the figure) for docking with a fluid connector 41 (see below) on the base station 20. The cleaning component 14 is further provided with a hollow middle shaft 144 extending along the left-right direction, which is fixedly arranged at the second end of the roller body 142 and connected to the pin shaft 173. The pin shaft 173, the middle shaft 144 and the inner cavity 141 are in fluid communication in sequence, and the inside of the pin shaft 173 and the inside of the middle shaft 144 form a downstream flow channel connected to the external interface, which is part of a first fluid passage (see below).

[0049] The upright body 2 extends along a longitudinal direction and includes a connecting end 21 close to the cleaning base 1, a handle portion 23 away from the connecting end 21, and a main body portion 22 between the connecting end 21 and the handle portion 23.

[0050] The handle portion 23 includes a grip 231 held by a user and a controller 232 arranged on the grip 231, which is used by the user to control the operation of the surface cleaning device 10. The connecting end 21 is rotatably connected to the rear of the cleaning base 1, which facilitates the user to adjust the angle of use to store the surface cleaning device 10 or the handle 231 and push the cleaning base 1 to move on the surface to be cleaned.

[0051] The main body portion 22 is provided with a plurality of working components of the surface cleaning device 10, including a cleaning liquid tank 24 capable of storing and providing cleaning liquid, a dirty liquid tank 25 capable of receiving and storing dirty liquid, a suction motor 26 capable of forming a suction flow, and a rechargeable battery 27 capable of providing external power.

[0052] The cleaning liquid tank 24 is detachably mounted at the top of the main body portion 22, so as to facilitate the user to add cleaning liquid thereto. The cleaning liquid tank 24 is in fluid communication with the inner cavity 141 of the cleaning component 14 and forms a first fluid passage (not shown in the figure) extending from the cleaning liquid tank 24 to the inner cavity 141. The external interface is connected to the first fluid passage and the connection therebetween divides the first fluid passage into an upstream passage and a downstream passage.

[0053] The upstream passage is further provided with a selectively activated liquid supply pump (not shown in the figure) to selectively deliver the cleaning liquid in the cleaning liquid tank 24 to the inner cavity 141 or block the fluid flow between the cleaning liquid tank 24 and the inner cavity 141. Further, the external interface is further provided with a one-way valve configured to be closed in a natural state to prevent the cleaning liquid in the first fluid passage from flowing out, and to be opened when docked with the fluid connector 41 to allow the fluid in the base station 20 to enter the inner cavity 141 of the cleaning component 14.

[0054] In other embodiments, the side brush can also be cancelled, and the outer interface directly communicates with the inner cavity of the cleaning component; a fluid distributor facing the cleaning component and having a plurality of nozzles can also be arranged on the cleaning base, and the end of the first fluid passage communicates with the fluid distributor to distribute cleaning liquid to the cleaning component, in which case the cleaning component can also be one or more brush discs arranged left and right. The specific type of cleaning component and the path arrangement of the first fluid passage do not limit the protection scope of the present application on the premise that the outer interface communicates with the first fluid passage and the first fluid passage can distribute cleaning liquid to the cleaning component.

[0055] The suction motor 26 and the suction nozzle 16 of the cleaning base 1 form a fluid path for the suction flow. When the suction motor 26 is started, the suction flow carrying the dirty liquid of the surface to be cleaned enters the fluid path through the swivel cavity 13. The dirty liquid tank 25 is arranged on the fluid path to receive and store the dirty liquid carried by the suction flow.

[0056] The rechargeable battery 27 is electrically connected to each of the electrical components of the surface cleaning device 10 to provide electrical energy to these electrical devices. The upright body 2 is also provided with an electrical connection terminal 28 electrically connected to the rechargeable battery 27 and exposed to the outside, which can connect the rechargeable battery 27 to the mains and charge it.

[0057] Referring to Figures 5-8 , the base station 20 includes a housing 3, a cleaning system capable of cleaning the cleaning component 14, a blowing system capable of delivering blowing air to the cleaning component 14, a charging system capable of charging the rechargeable battery 27, a dirty liquid recovery system capable of recovering dirty liquid, and a second fluid passage arranged inside the housing 3.

[0058] The housing 3 includes a tray 31 arranged at the bottom and a pedestal 32 fixedly arranged on the upper side of the tray 31. The tray 31 is configured to accommodate the cleaning base 1 of the surface cleaning device 10, and the pedestal 32 extends substantially in the vertical direction and is configured to support the rear part of the upright body 2.

[0059] The tray 31 has a bottom part 311 capable of supporting the cleaning base 1 and an outer peripheral wall 312 extending circumferentially along the outer edge of the bottom part 311. The front part of the bottom part 311 is recessed downward and forms a recess 313 extending in the left-right direction and configured to accommodate the cleaning component 14 of the surface cleaning device 10. The outer peripheral wall 312 protrudes upward relative to the bottom part 311 to confine the dirty liquid generated when the cleaning component 14 is cleaned within the tray 31.

[0060] The second fluid passage includes a fluid connector 41 fixedly disposed on the peripheral wall 312 and a common pipe 42 in fluid communication with the fluid connector 41. The common pipe 42 is a flexible hose disposed inside the tray 31 and has a first end portion (not shown) and a second end portion (not shown) distal to each other. The fluid connector 41 has a fluid inlet (not shown) and a fluid outlet (not shown) in communication with each other, the fluid inlet of which is in communication with the first end portion of the common pipe 42 for fluid in the fluid passage to flow into the fluid connector 42, and the fluid outlet of which is configured to be in communication with the external interface of the surface cleaning device 10 when the surface cleaning device 10 is placed on the base station 20 and to open a one-way valve on the external interface to connect the second fluid passage with the first fluid passage.

[0061] The cleaning system includes a supply tank 51 capable of storing and externally providing cleaning liquid and a supply pump 52 in fluid communication with the supply tank 51. The supply tank 51 is fixedly disposed on the side of the housing 3. The second end portion of the common pipe 42 is bifurcated and formed with two separate branches, one of which is in communication with the outlet of the supply pump 52. The supply pump 52 is located inside the housing 3 and is configured to be selectively activated to selectively deliver cleaning liquid in the supply tank 51 to the common pipe 42 or to block the fluid flow between the supply tank 51 and the common pipe 42.

[0062] The blowing system includes a fan assembly 61 capable of externally blowing air and a heating wire assembly 62 capable of heating air. The fan assembly 61 and the heating wire assembly 62 are both disposed inside the tray 31, and the heating wire assembly 62 is disposed at the air outlet end of the blowing system. The other branch of the second end portion of the common pipe 42 is connected to the air outlet end of the blowing system to connect the blowing system with the fluid connector 41.

[0063] The charging system includes an electrical connector 71 disposed on the top of the pedestal 32 and a conductive wire 72 electrically connected to the electrical connector 71. When the surface cleaning device 10 is placed on the base station 20, the pedestal 32 supports the rear portion of the upright body 2, the electrical connector 71 is in abutment with the electrical terminal 28 and forms an electrical connection, and the conductive wire 72 can charge the rechargeable battery 27 after being connected to a power supply.

[0064] The dirty liquid recovery system includes a recovery tank 81 capable of receiving and storing dirty liquid, a recovery passage 82 in fluid communication with the recovery tank 81, and a recovery pump (not shown) located on the recovery passage 82. The recovery tank 81 is fixedly disposed on the side of the housing 3, and the recovery passage 82 is in fluid communication with the recess 313 at the side end portion distal to the recovery tank 81. The recovery passage 82 is also composed of a flexible tube and is independent of the second fluid passage. The recovery pump is configured to be selectively activated to recover the dirty liquid at the recess 313 when the base station 20 cleans the cleaning component 14.

[0065] The working principle of the base station 20 is described as follows: when the surface cleaning device 10 is placed on the base station 20, the cleaning base 1 is supported on the bottom portion 311 of the base station 20, and the cleaning member 14 is located at the recess 313 of the base station 20. The driving motor of the surface cleaning device 10 is started and drives the cleaning member 14 to rotate; the liquid supply pump is started, and the cleaning liquid in the supply tank 51 flows through the common pipeline 42, the fluid connector 41, the first fluid passage, and the inner cavity 141 in sequence and finally reaches the bristle layer 143 of the cleaning member 14 through the through hole in the roller body 142 to clean the cleaning member 14; the recovery pump is started to recover the dirty liquid at the recess 313. After the cleaning of the cleaning member 14 is completed, the fan assembly 61 and the heating wire assembly 62 are both started, and the hot air flow generated by the blowing system flows through the common pipeline 42, the fluid connector 41, the first fluid passage, and the inner cavity 141 in sequence and finally reaches the bristle layer 143 of the cleaning member 14 through the through hole in the roller body 142 to dry the cleaning member 14.

[0066] As can be seen from the above, since part of the first fluid passage is borrowed, the base station 20 does not need to be arranged with a spray head or the like to guide the cleaning liquid to the cleaning member 14, thereby simplifying the structure of the base station 20 and reducing the manufacturing cost. In addition, by integrating the second fluid passage, the pipeline arrangement in the base station 20 is reduced, further simplifying the structure of the base station 20 and reducing the volume of the base station 20, which is convenient for users to store the base station.

[0067] It should be noted that the upright surface cleaning device 10 provided in the embodiment is only a non-limiting example. In other embodiments, a self-moving surface cleaning device, i.e., a cleaning robot, can also be used. It can be understood that after the tray shape and the charging seat position of the base station are adapted, all the functions of the base station described above can be achieved.

[0068] The above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made in accordance with the spirit of the present application should be covered within the protection scope of the present application.
