According to one embodiment of the present disclosure, a base station is provided. Wherein the base station can be used to dock an autonomous surface cleaning apparatus such as a sweeping robot.

The surface cleaning apparatus may include a generally circular or rectangular plus circular housing. As shown in fig. 1 and 2, the surface cleaning apparatus 10 can include a wet cleaning portion and a dry cleaning portion. Wherein the wet cleaning part and the dry cleaning part may be disposed at a bottom of the housing, and may be in contact with the cleaning surface to perform wet cleaning and dry cleaning of the cleaning surface.

The wet cleaning part may include a first rotating member 11 and a second rotating member 12, and a mopping member (not shown in the drawings) such as a mop cloth, etc. may be provided on the first rotating member 11 and the second rotating member 12, respectively. The first rotating member 11 and the second rotating member 12 are arranged in parallel and can rotate around the rotating shafts, respectively, so as to mop the cleaning surface while the first rotating member 11 and the second rotating member 12 are in contact with the cleaning surface. A cleaning liquid receiving portion may be provided inside the housing of the surface cleaning apparatus, and the cleaning liquid is supplied to the mop through the cleaning liquid supply port, so that the cleaning surface is wet-cleaned by the cleaning liquid adsorbed by the mop.

In certain cleaning scenarios where stubborn stains and the like need to be cleaned, the pressure provided can cause the mop of the wet cleaning portion to more closely contact the cleaning surface, which can result in better cleaning. Further, although in the present disclosure the wet cleaning portion is in the form of two rotating members, it will be appreciated that it may be provided as one rotating member, for example the rotating member may be a tracked rotating member, and the tracked rotating member may be arranged to rotate in or against the direction of travel of the surface cleaning apparatus to effect wet cleaning of the cleaning surface.

Fig. 3 shows a base station 20 according to an embodiment of the present disclosure. Wherein the base station can interface with the surface cleaning apparatus. When the surface cleaning device is docked to the base station, dust, debris and other debris collected in the dust collection portion of the surface cleaning device is sucked to the base station to evacuate the dust collection portion of the surface cleaning device, and/or to charge the surface cleaning device, and/or to clean a mop of the surface cleaning device, and/or to replenish a cleaning liquid containing portion of the surface cleaning device with cleaning liquid.

As shown in fig. 3, the base station 20 may include a base assembly 100, a dust collecting device 200, and a cleaning device 300.

The base assembly 100 can provide a receiving space for receiving the surface cleaning apparatus, when a portion of the surface cleaning apparatus enters the base assembly 100, the surface cleaning apparatus can be charged through a charging interface 120 provided in the base assembly 100, and/or dust, debris and other debris collected in the dust collecting portion can be sucked into the dust collecting apparatus 200 through a suction interface 130 provided in the base assembly 100, and/or cleaning liquid can be replenished to the cleaning liquid receiving portion of the surface cleaning apparatus through a liquid replenishing interface 140 provided in the base assembly 100; and/or the mop of the surface cleaning apparatus may be cleaned by a cleaning portion provided in the base assembly 100.

The dust collecting device 200 has a main function of sucking dust, debris, and other debris collected in a dust collecting part of the surface cleaning apparatus and storing the sucked debris. The cleaning device 300 may include a cleaning liquid storage portion and a recovery liquid storage portion, and may be connected by a conduit to supply the cleaning liquid stored in the cleaning liquid storage portion to the fluid replacement interface of the base assembly 100, to supply the cleaning liquid to the surface cleaning device, and to draw the recovery liquid, which self-cleans the mop of the surface cleaning device, from the washing portion of the base assembly 100 to the recovery liquid storage portion through the conduit.

In the present disclosure, the dust collecting device 200 and the cleaning device 300 can be selectively used in cooperation with the base assembly 100, so that it is possible to construct a base station having different maintenance modes. As shown in fig. 4, the self-emptying mode among the different maintenance modes can be achieved by cooperating the dust collection device 200 with the base assembly 100. When the dust collection device 200 is combined with the base assembly 100, the dust suction function of the dust collection part of the surface cleaning device can be realized, so that the dust of the dust collection part of the surface cleaning device can be emptied into the dust collection device 200, and the self-emptying function of the surface cleaning device can be realized. As shown in fig. 5, the cleaning device 300 may be engaged with the base assembly 100 to implement a self-cleaning mode and/or a cleaning liquid replenishment mode of different maintenance modes. Combining the cleaning apparatus 300 with the base assembly 100 may enable self-cleaning of a mop of the surface cleaning apparatus and/or may enable replenishment of a cleaning liquid receptacle of the surface cleaning apparatus with cleaning liquid. In addition, as shown in FIG. 3, the dust collecting device 200 and the cleaning device 300 can be used in combination with the base assembly 100 to realize a self-emptying mode, a self-cleaning mode, and/or a liquid replenishing mode among different maintenance modes. Specifically, debris from the debris collection portion of the surface cleaning apparatus can be drawn through the debris collection device 200 to empty the debris from the debris collection portion of the surface cleaning apparatus, and cleaning fluid can be replenished and/or provided to the cleaning fluid receptacle of the surface cleaning apparatus through the cleaning apparatus 300 to clean the mop of the surface cleaning apparatus. In addition, the base assembly 100 may be used alone to enable charging of the surface cleaning apparatus, and it should be noted that even after the base assembly 100 is combined with the dust collection apparatus 200 and/or the cleaning apparatus 300, the charging mode may be simultaneously selected after the corresponding mode of the dust collection apparatus 200 and/or the cleaning apparatus 300 is selected. Although the functions of the dust collecting device 200 and the cleaning device 300 are explicitly defined in the present disclosure, these are only examples, and it will be understood by those skilled in the art that maintenance components having other functions may be selected to be used with the base component or to employ a single-function maintenance component or to employ a function-integrated maintenance component, etc.

According to the base station of the present disclosure, a user may select different components as desired to mate with a corresponding surface cleaning apparatus, such as the dust collection apparatus 200 and/or the cleaning apparatus 300, to be removably attached to the base assembly 100. For example, for a surface cleaning apparatus that performs only dry cleaning, the base assembly 100 can be selected to charge the surface cleaning apparatus, and if it is desired to empty the dust collecting portion of the surface cleaning apparatus, the dust collecting apparatus 200 can be selected and mated with the base assembly 100 to empty the dust collecting portion of the surface cleaning apparatus, thereby allowing for a self-emptying mode and/or a charging mode. For example, in the event that emptying of the dust collection portion of the surface cleaning apparatus is not required, only the cleaning apparatus 300 and base assembly 100 may be selected, and only the self-cleaning mode, the liquid replenishment mode, and/or the charging mode may be performed. In addition, according to the combinable base station of the present disclosure, if a certain component is updated at a later stage, a user can easily replace the previous component to use the updated component. The base station of the existing surface cleaning device is generally single in function, but for a multifunctional base station, the size is large, the use cost of a user is high, and the base station cannot be switched according to the user requirement. Therefore, the combinable base station according to the present disclosure can solve the problems existing in the existing base station and allow the user to accept or reject certain functions through the selection of hardware.

According to an alternative embodiment of the sectional base station of the present disclosure, the base assembly 100 may be designed to be disposed at a lower portion, the dust collecting device 200 may be designed to be disposed at a middle portion, and the cleaning device 300 may be designed to be disposed at an upper portion. But the setting position may be changed according to the actual situation. Further, the dust collection device 200 and the cleaning device 300 are respectively provided with a combined portion combined with the base assembly 100. In addition, other functional components can be arranged to realize other working modes according to actual needs.

Further, although the external views using the dust collection device 200 and the cleaning device 300 are illustrated in fig. 4 and 5, that is, they may be accommodated in different housings. In the present disclosure, however, the dust collection device 200 and the cleaning device 300 may share one assembly housing. The dust collection device 200 and the cleaning device 300 are both mounted into the assembly housing. Thus, in the case where the user only needs the dust collection device 200, the dust collection device 200 can be assembled only in the module case, in the case where only the cleaning device 300 is needed, the cleaning device 300 can be assembled only in the module case, and in the case where the dust collection device 200 and the cleaning device 300 are needed, the dust collection device 200 and the cleaning device 300 can be assembled in the module case. By the mode, the product can be assembled before being delivered to a user, so that the problem of the user in the assembling process is avoided, and the user can select different functions according to the requirement of the user.

To allow the maintenance assembly to be reliably disposed on the base assembly 100, mounting structures may be provided on the functional assembly that interfaces with the base assembly 100. For example, in the case where the dust collection device 200 and the cleaning device 300 are provided with separate housings, the dust collection device 200 or the cleaning device 300 may be provided with a mounting structure. When the dust collection device 200 and the cleaning device 300 share a module case, a mounting structure may be provided on the module case. As one example, the mounting structure may include an insert and a latch, and the insert may be disposed at the maintenance assembly and the latch may be disposed at the base assembly. As shown in fig. 7, an insertion opening 611 may be provided in the base member 100, and the insertion opening 611 may be inserted by an insertion member provided in the maintenance member. And the insert may be locked by the locking members 612 after insertion. In an alternative embodiment, an insert may be provided in the base assembly and an insert port may be provided in the maintenance assembly, and a latch may be provided on either the base assembly or the maintenance assembly. In addition, the base assembly and the maintenance assembly are locked, so that a user can conveniently carry the base station. Also, in the case where the dust collection device 200 and the cleaning device 300 share a component housing, the volume of the base can be effectively reduced.

Fig. 6 and 7 illustrate a front view and a perspective view, respectively, of one embodiment of a base assembly 100. Referring to fig. 6 and 7, the base assembly 100 may include a base housing to form a space to house at least a portion of the surface cleaning apparatus. Wherein the base housing may include a first housing 111 (a rear housing shown in fig. 6), a second housing 112 (a left housing shown in fig. 6), and a third housing 113 (a right housing shown in fig. 6). The first, second and third housings 111, 112, 113 form a semi-enclosed space into which at least a portion of the surface cleaning apparatus enters when the surface cleaning apparatus is docked to the base assembly 100, wherein at least a portion of the rear side of the surface cleaning apparatus on which the mopping element is provided enters the semi-enclosed space, and may be integrally formed. Further, the base assembly 100 may also include a fourth housing 114 (the lower housing shown in fig. 7). The fourth housing 114 may include a support portion 115 and a ramp portion 116. The support portion 115 may be used to support at least a portion of the rear side of the surface cleaning apparatus. The ramp portion 116 may provide a passage that allows the surface cleaning apparatus to enter the semi-enclosed space.

The base assembly 100 may include a charging interface 120. When the surface cleaning apparatus is docked in place in the base assembly 100, the charging interface provided at the surface cleaning apparatus may be in contact with the charging interface 120 of the base assembly 100 and the surface cleaning apparatus is charged through the charging interface 120 connected to a power supply such as an external power supply. Wherein the charging interface 120 is elastically telescopic for better intimate abutment with the charging interface of the surface cleaning apparatus. Charging connector 120 may be disposed on an inner side of first housing 111, second housing 112, or third housing 113, where charging connector 120 is shown disposed on the inner side of first housing 111. And the charging interface 120 is arranged at a predetermined height position above the support portion 115, it is possible to avoid that the liquid affects the charging when washing the mop of the surface cleaning apparatus.

According to an alternative embodiment of the present disclosure, the base assembly 100 may include a suction port 130, and the suction port 130 may be interfaced with a suction port 15 (shown in fig. 1) of the surface cleaning apparatus and thus may be in communication with a dirt collection portion of the surface cleaning apparatus such that, in a self-emptying mode using the dirt collection apparatus 200, dirt of the integrated portion of the surface cleaning apparatus is drawn into the dirt collection apparatus 200 via the interface 131 via the interfaced suction port 130 and the suction port 15. The outside of the suction interface 130 may be provided with a suction seal, wherein the suction seal may surround the outside of the suction interface 130 and may be made of an elastic material to form a seal of the gas passage when the suction port 15 abuts the suction interface 130 to form a pneumatic engagement when the surface cleaning apparatus is parked in place with the base assembly 100. Alternatively, the suction port 130 may be provided on an inner side of the base assembly 100, for example, may be provided on an inner side of the first casing 111, or the second casing 112, or the third casing 113. Fig. 6 and 7 show that the suction connection 130 is arranged on the inner side of the third housing 113.

Optionally, the base assembly 100 may include a fluid replacement interface 140, wherein the fluid replacement interface 140 may be disposed on an inner side of the base assembly 100 and made of a flexible material, and the fluid replacement interface 140 may be bent when subjected to a certain pressure. Thus, for example, it may be disposed on the inner side of the first casing 111, the second casing 112, or the third casing 113. Fig. 6 and 7 show that the suction connection 130 is arranged on the inner side of the first housing 111. The fluid infusion port 140 may extend outward from a surface of an inner side of the base assembly 100 by a predetermined length, and the fluid infusion port 140 may be extended and retracted to be inserted into a fluid infusion port provided on the surface cleaning apparatus when the base assembly 100 is parked by the surface cleaning apparatus made of an elastic material. Because the fluid replacement interface 140 is flexible, when the fluid replacement interface 140 is misaligned with the fluid replacement port of the surface cleaning apparatus, the fluid replacement interface 140 can be bent during insertion to prevent damage to the surface cleaning apparatus, and the fluid replacement interface 140 can be bent to ensure that the fluid replacement interface 140 is well inserted into the fluid replacement port of the surface cleaning apparatus during extension and retraction. The fluid replenishment interface 140 may be in fluid communication with the cleaning apparatus 300 via a conduit to provide cleaning fluid from the cleaning apparatus 300 to the surface cleaning apparatus for purposes of cleaning fluid replenishment. In the present disclosure, it is preferable that the fluid infusion interface 140 and the suction interface 130 are respectively disposed at both sides of the charging interface 120.

In the present disclosure, the charging mode and the other maintenance modes may be performed simultaneously, that is, the charging mode is performed while the other maintenance modes are performed. The charging mode may be initiated, for example, while performing a self-emptying mode, a self-cleaning mode, and/or a liquid replenishment mode.

Optionally, the base assembly 100 may include guide wheels 150. When the surface cleaning apparatus enters the base assembly 100, the guide wheels 150 can contact the sides of the surface cleaning apparatus and guide the surface cleaning apparatus into the receiving space in which the surface cleaning apparatus is received. In the present disclosure, the number of the guide wheels 150 may be two, and the two guide wheels 150 are respectively disposed at inner side surfaces of the second and third housings 112 and 113. The guide wheels 150 may be positioned at positions outside the inner side surfaces of the second and third housings 112 and 113 so that when the surface cleaning apparatus enters the accommodating space, the surface cleaning apparatus first contacts the guide wheels 150, and the surface cleaning apparatus is parked in place in the accommodating space by the guide of the guide wheels 150.

The supporting portion 115 of the base assembly 100 may be provided with a cleaning portion. A concave cleaning space with a closed periphery and bottom may be formed on the supporting portion 115, and the recovery liquid may be stored in the closed cleaning space.

Liquid channel 1155 can receive liquid from cleaning device 300 via a conduit and direct the liquid to a washing section for washing the mop of the surface cleaning device. The drain port 1152 may supply the cleaned recovery liquid to the cleaning apparatus 300 through a pipe to perform a recovery function of the recovery liquid, wherein a filter device may be provided at the position of the drain port 1152. In addition, the washing part may further include brush members 1153, the number and positions of the brush members 1153 may correspond to those of the rotating members of the surface cleaning apparatus, and in the present disclosure, the number of the brush members 1153 may be two, and the mopping member is brushed by the brush members 1153 while the rotating members are rotated, thereby achieving the self-cleaning function of the mopping member. A guide 1156 may also be provided at the cleaning portion, so that when the surface cleaning apparatus enters, the surface cleaning apparatus can be guided by the guide 1156 and can also serve as a support for the surface cleaning apparatus. For example, as shown in fig. 2, rollers 16 of surface cleaning apparatus 10 may be moved along guide 1156 and supported.

The washing section may further include a drying port 1154 for drying the mop of the surface cleaning apparatus, and the drying port 1154 may be provided at a position corresponding to the mop. In the present disclosure, it is preferable that the drying port 1154 is provided on the fourth housing 114 (the lower housing shown in fig. 7), and the drying port 1154 has a predetermined height with respect to the bottom surface of the fourth housing 114 in order to prevent liquid from entering. The drying ports 1154 may occupy a certain area and may provide a hot airflow from the bottom of the mop, which may achieve better drying. The drying port 1154 may be in gaseous communication with the cleaning device 300 via a conduit to receive a flow of air from the cleaning device 300 and the flow of air may be heated to provide a flow of air to the mop to achieve a drying function of the mop. In the present disclosure, the drying port 1154 may be provided at a position having a certain height with respect to the bottom of the washing space, and the number of the drying ports may be one or more. The drying opening is configured to extend in a radial direction of the mop in order to cover a larger area of the mop.

Wherein the base housing may include a first housing 111 (a rear housing shown in fig. 9), a second housing 112 (a left housing shown in fig. 9), and a third housing 113 (a right housing shown in fig. 9). The first, second and third housings 111, 112, 113 form a semi-enclosed space into which at least a portion of the surface cleaning apparatus enters when the surface cleaning apparatus is docked to the base assembly 100, wherein at least a portion of the rear side of the surface cleaning apparatus, on which the mop is disposed, enters the semi-enclosed space, and may be integrally formed. Further, the base assembly 100 may also include a fourth housing 114 (a lower housing shown in fig. 10). The fourth housing 114 may include a support portion 115 and a ramp portion 116. The support portion 115 may be used to support at least a portion of the rear side of the surface cleaning apparatus. The ramp portion 116 may provide a passage that allows the surface cleaning apparatus to enter the semi-enclosed space.

The base assembly 100 may include a charging interface 120. When the surface cleaning apparatus is docked in place in the base assembly 100, the charging interface provided at the surface cleaning apparatus may be in contact with the charging interface 120 of the base assembly 100 and the surface cleaning apparatus is charged through the charging interface 120 connected to a power supply such as an external power supply. Wherein the charging interface 120 is elastically telescopic for better tight abutment with the charging interface of the surface cleaning apparatus. Charging connector 120 may be disposed on an inner side of first housing 111, second housing 112, or third housing 113, where charging connector 120 is shown disposed on the inner side of first housing 111. And the charging interface 120 is arranged at a predetermined height above the support portion 115, which avoids that liquid influences the charging when washing the mop of the surface cleaning apparatus.

According to an alternative embodiment of the present disclosure, the base assembly 100 may include a suction port 130, and the suction port 130 may be interfaced with a suction port 15 (shown in fig. 1) of a surface cleaning apparatus, such that it may be in communication with a dirt collection portion of the surface cleaning apparatus, such that, in a self-emptying mode using the dirt collection apparatus 200, dirt of the integrated portion of the surface cleaning apparatus is drawn into the dirt collection apparatus 200 via the interface 131 via the interfaced suction port 130 and the suction port 15. The outside of the suction interface 130 may be provided with a suction seal, wherein the suction seal may surround the outside of the suction interface 130 and may be made of an elastic material to form a seal of the gas passage when the suction port 15 is brought into pneumatic engagement against the suction interface 130 when the surface cleaning apparatus is docked in position with the base assembly 100. Alternatively, the suction port 130 may be provided on an inner side of the base assembly 100, for example, may be provided on an inner side of the first casing 111, or the second casing 112, or the third casing 113.

Optionally, the base assembly 100 may include a fluid replacement interface 140, wherein the fluid replacement interface 140 may be disposed on an inner side of the base assembly 100, for example, may be disposed on an inner side of the first housing 111, or the second housing 112, or the third housing 113. Fig. 9 and 10 show that the suction connection 130 is arranged on the inner side of the first housing 111. The fluid replacement port 140 may extend outward from a surface of the inner side of the base member 100 by a predetermined length, may be made of an elastic material, and may be bent when subjected to a certain pressure. Thus, when the surface cleaning apparatus is docked in the base assembly 100, the fluid replacement interface 140 can be extended and retracted for insertion into a fluid replacement port provided on the surface cleaning apparatus. Because fluid replacement interface 140 is flexible, fluid replacement interface 140 can bend during insertion to prevent damage to the surface cleaning apparatus when fluid replacement interface 140 is misaligned with the fluid replacement port of the surface cleaning apparatus, and because fluid replacement interface 140 can bend, fluid replacement interface 140 can be guaranteed to be well inserted into the fluid replacement port of the surface cleaning apparatus during extension and retraction. The fluid replenishment interface 140 may be in fluid communication with the cleaning apparatus 300 via a conduit to provide cleaning fluid from the cleaning apparatus 300 to the surface cleaning apparatus for purposes of cleaning fluid replenishment. Preferably, the fluid infusion interface 140 and the suction interface 130 are respectively disposed at both sides of the charging interface 120.

In the present disclosure, the charging mode and the other maintenance modes may be performed simultaneously, that is, the charging mode is performed while the other maintenance modes are performed. The charging mode is initiated, for example, while the self-emptying mode, self-cleaning mode, and/or liquid replenishment mode is in progress.

Optionally, the base assembly 100 may include guide wheels 150. When the surface cleaning apparatus enters the base assembly 100, the guide wheels 150 can contact the sides of the surface cleaning apparatus and guide the surface cleaning apparatus into the receiving space in which the surface cleaning apparatus is received. In the present disclosure, the number of the guide wheels 150 may be two, and the two guide wheels 150 are respectively disposed at inner side surfaces of the second and third housings 112 and 113. The position of the guide wheels 150 may be at a position outside the inner side surfaces of the second and third housings 112 and 113 so that when the surface cleaning device enters the accommodating space, the surface cleaning device first contacts the guide wheels 150, and the surface cleaning device is parked in place in the accommodating space by the guide of the guide wheels 150.

The supporting portion 115 of the base assembly 100 may be provided with a cleaning portion. The supporting portion 115 may be formed with a recessed closed space having a closed periphery and a closed bottom, and the recovery liquid may be stored in the closed space. Fig. 11 shows a cross-sectional view according to the section a-a shown in fig. 9. As shown in fig. 11, the washing section may include a liquid outlet 1151 and a liquid outlet 1152. Outlet port 1151 may be in fluid communication with cleaning apparatus 300 and cleaning liquid provided by cleaning apparatus 300 may be ejected from outlet port 1151 to provide cleaning liquid to a mop of the surface cleaning apparatus. The drain port 1152 may supply the cleaned recovery liquid to the cleaning apparatus 300 through a pipe to perform a recovery function of the recovery liquid. In addition, the washing part may further include brush members 1153, the number and positions of the brush members 1153 may correspond to those of the rotary members of the surface cleaning apparatus, and in the present disclosure, the number of the brush members 1153 may be two, and the spin member brushes the spin member mounted to the rotary member through the brush members 1153, thereby achieving the self-cleaning function of the spin member. The washing part may further include a drying port 1154 for drying the mop, and the drying port 1154 may be provided at a position corresponding to the mop and at a position spaced apart from the bottom surface of the supporting part 115 by a predetermined height. The drying port 1154 may be in gaseous communication with the cleaning device 300 via a conduit to receive drying gas from the cleaning device 300 and provide it to the mop to perform the drying function of the mop.

Further, according to some embodiments of the present disclosure, a seal structure 1161 may be provided on the ramp portion 116. Wherein the sealing structure 1161 may be recessed relative to the surface of the ramp portion 116 and the sealing structure 1161 is shaped to match the corresponding shape of the roller portion of the surface cleaning apparatus such that the sealing structure 1161 may hermetically close the opening of the roller portion when the surface cleaning apparatus is resting on the base assembly 100. After sealing, the suction nozzle for sucking the debris at the rolling brush part is sealed. At this time, inside the surface cleaning apparatus, a first air flow path from the suction nozzle near the drum brush section to the dust collection section is blocked, and a second air flow path from the dust collection section of the surface cleaning apparatus to the suction port 15 is opened. By closing the first air flow path, a greater suction force can be provided so that a better emptying of debris, such as debris, in the dust collecting part is possible. According to an alternative embodiment of the present disclosure, an elastic barrier may be provided at a position of the base assembly 100 corresponding to the brush roll portion, so that when the surface cleaning apparatus is returned to the base assembly 100, the elastic barrier may be bounced to close a suction nozzle of the brush roll portion, or the like.

Fig. 12 illustrates an external schematic view of a dust collection apparatus according to one embodiment of the present disclosure. The dust collecting device 200 has a main function of sucking dust, debris, and other debris collected in a dust collecting part of the surface cleaning apparatus and storing the sucked debris. The dust collecting device 200 may be used in combination with the base assembly 100, or may be used in combination with the cleaning device 300. For example, the dust collecting device 200 may be detachably coupled to the upper surface of the base assembly 100, and the dust collecting device 200 may be integrally formed with the base assembly 100 after the coupling.

As shown in fig. 12, the dust collection device 200 may include a dust collection device housing 210 and a dust collection separator 220. Wherein, the side of the dust collecting device housing 210 is provided with an opening, and the dust collecting separator 220 can be detachably mounted into the dust collecting device housing 210 through the opening. Wherein a detachable direction of the dust collecting separator 220 with respect to the dust collecting device housing 210 is substantially parallel to a ground direction in which the base station is provided. After the dust collecting apparatus 200 with the dust collecting separator 220 mounted thereon is assembled to the base assembly 100, the dust collecting separator 220 is in fluid communication with the suction port 130 of the base assembly 100 through a pipe. This allows the debris in the dirt collection portion of the surface cleaning apparatus to be drawn into the storage space of the dirt-collecting separator 220 to effect emptying of the dirt collection portion. Alternatively in the present disclosure, the receiving volume of the dust collecting separator 220 may be set to at least three times or more of the receiving volume of the dust collecting part of the surface cleaning apparatus. When it is necessary to detach the dust collecting separator 220 from the dust collecting device housing 210, the user can press it, and the dust collecting separator 220 is ejected by the elastic force.

Fig. 13 shows a schematic view of the dust collecting device 200 shown in fig. 12 with its outer housing removed. As shown in fig. 13, the dust collection device 200 can include a first suction source 230, which first suction source 230 can be in the form of a fan, and disposed inside the dust collection device housing 210. In the present disclosure, the first suction source 230 and the dust collecting separator 220 may be disposed right and left of the dust collecting device case 210. The suction airstream is created by the first suction source 230 such that a negative pressure condition is created by the suction airstream such that debris, such as dirt and debris, from the surface cleaning apparatus enters the suction passage of the dirt separator 220 via the suction interface and corresponding ducting, for example the suction passage may interface with ducting ports provided in the upper surface of the base assembly 100. Then, the dust and the like are sucked into the inner space defined by the housing of the dust-collecting separator 220 through the suction inlet port.

Fig. 14 shows a schematic view of another angle of the dust collecting separator. Wherein the dust-collecting separator 220 defines a receiving space for receiving and accommodating the garbage by its housing. The dirt separator 220 can include a suction inlet port 226, wherein the suction inlet port 226 can communicate with the suction interface 130 through a conduit to allow dust, debris, and the like debris to enter the interior of the dirt separator 220. According to an embodiment of the present disclosure, as shown in fig. 15, the dust collection separator 220 may further include a first gas outlet 227 and a second gas outlet 228. Wherein in an alternative embodiment of the present disclosure, the suction inlet port 226 is provided at one side of the housing of the dust-collecting separator 220, and the first and second gas outlets 227 and 228 may be provided at the other side of the housing of the dust-collecting separator 220. The one side and the other side may be two opposite sides of the housing of the dust collecting separator 220. And the suction inlet port 226 and the first gas outlet 227 may be offset to the left with respect to the center line of the dust collecting separator 220, and the second gas outlet 228 may be offset to the right with respect to the center line of the dust collecting separator 220.

As shown in fig. 15, the dust collecting separator 220 may further include an air passage switching device 250, which may be formed of a plate-shaped body portion, disposed adjacent to the housing of the dust collecting separator. Fig. 13 shows a case where the air passage switching device 250 is attached to the housing of the dust collecting separator 220, and fig. 15 shows a case where the air passage switching device 250 is separated from the housing of the dust collecting separator 220. The air duct switching device 250 may be a structure in which the air duct is switched, and may be set in a first state and a second state. In the first state, the air duct switching device 250 may open the first gas outlet 227 and close the second gas outlet 228, and in the second state, the air duct switching device 250 may close the first gas outlet 227 and open the second gas outlet 228. In the present disclosure, the first gas outlet 227 may be disposed at a position closer to the suction inlet port 226. Alternatively, the axis of the first gas outlet 227 may coincide with the axis of the suction inlet port 226, or the axis of the first gas outlet 227 may be nearly coincident with the axis of the suction inlet port 226, or the axis of the first gas outlet 227 may lie in a plane perpendicular to the bottom side surface of the dust collecting separator 220 in parallel with the axis of the suction inlet port 226. For example, the first gas outlet 227 may be provided at a position closer to the suction inlet 226 at the front side. The second gas outlet 228 may be arranged at a position further away from the suction inlet 226 than the distance between the first gas outlet 227 and the suction inlet 226, for example, the second gas outlet 228 and the suction inlet 226 may be arranged in a nearly diagonal manner, for example, the central axis of the second gas outlet and the central axis of the suction inlet are slightly smaller than the length of the receiving space.

In an alternative embodiment of the present disclosure, the receiving space of the dust collecting separator 220 may be provided with a cyclone separator or a dust bag. That is, the dust collecting separator 220 may employ an interchangeable structure of a cyclone separator and a dust bag. Fig. 16 shows a schematic view of the end cap portion 270 of the dust collecting separator 220 removed to show the interior space of the dust collecting separator 220. In the case of a cyclone installed as shown in fig. 16, a mounting structure 241 may be provided on an inner sidewall of the dust collecting separator 220, and the cyclone 240 and the dust bag may be installed into the receiving space of the dust collecting separator 220 through the mounting structure 241, and an inlet of each of the cyclone and the dust bag is butted against the suction inlet port 226 to achieve fluid communication. Such that debris, such as dust, enters the cyclone separator or dirt bag through the suction inlet 226. As one example, mounting structures 241 may be provided at opposite sides of the suction inlet 226, and when mounting the cyclone separator, the cyclone separator may be snapped to the mounting structures 241 of both sides, and when mounting the dust bag, a mounting plate provided to the dust bag may be inserted into the mounting structure 241. In the present disclosure, the first gas outlet 227 serves as a wind outlet when the cyclone separator is used, and the second gas outlet 228 serves as a wind outlet when the dust bag is used. When the cyclone separator is used, the first gas outlet 227 is selected to select an air passage that is close to the suction inlet 226, dust and other debris is thrown by the cyclone separator into the receiving space formed by the housing of the dust collecting separator 220, and air is discharged through the first gas outlet 227 that is in abutment with the outlet of the cyclone separator. In the case of using the dust bag, the second gas outlet 228 is selected to select an air duct distant from the suction inlet 226, dust and the like are left in the dust bag provided in the accommodating space, and air is discharged through the second gas outlet 228. When the cyclone separator is used, the cyclone separator occupies a part of the accommodating space, for example, one third of the accommodating space, and the rest of the accommodating space is used as a space for storing garbage. By selecting the second gas outlet 228, and thus the remote air path, when the dirt bag is in use, the dirt bag can be made to fill the entire receiving space as the air flows through the dirt bag, thus making full use of the receiving space. As shown in fig. 15, the air channel switching device 250 may be provided with a first opening 251 and a second opening 252. The air duct switching device 250 is slidable with respect to the outer side surface of the dust collecting separator 220 so that one of the air outlets 227 and 228 serves as an air outlet according to the usage of the cyclone separator or the dust bag. When the cyclone separator is used, the air duct switching device 250 slides to a first state in which the first opening 251 of the air duct switching device 250 is located at the position of the first gas outlet 227, so that the first gas outlet 227 serves as an air discharge port for the recovered air flow, and the second gas outlet 228 is blocked by the air duct switching device 250. In the case of using the dust bag, the air-duct switching device 250 slides to the second state in which the second opening 252 of the air-duct switching device 250 is located at the position of the second gas outlet 228, so that the second gas outlet 228 serves as an air discharge port for the recovered air flow, and the first gas outlet 227 is blocked by the air-duct switching device 250. It should be noted that, although the air duct switching device provided with the first opening and the second opening is described as an example in the above description. It should be understood by those skilled in the art that the air channel switching device may take other forms as long as it can block one of the first and second air outlets and open the other during the switching process of the air channel switching device. For example, the air duct switching device may be provided in a plate shape without an opening, and the length thereof is designed according to the distance between the first gas outlet and the second gas outlet, and the corresponding function may be achieved.

Further, as shown in fig. 15, a recess portion may be provided at a corresponding portion of the dust collecting separator 220 so as to accommodate the air passage switching device, and a guide portion may be provided at the recess portion and the air passage switching device. By this guide portion, the air passage switching device can be mounted to the housing of the dust collecting separator 22. The guide portions may be, for example, guide projections of the housing of the dust collection separator 22 and guide grooves of the air passage switching device.

Alternatively, the dust separator 220 may include a discharge portion 223, and the discharge portion 223 may be closed to form a closed garbage accommodating space and opened to facilitate a user to discharge garbage (garbage collected by means of the cyclone separator) in the accommodating space. In an alternative embodiment, the discharge portion 223 may be in the form of a discharge door, and one side of the discharge door may be rotated about a side housing of the dust collecting separator 220 to be opened or closed. In addition, a locking member 224 may be provided at the other side of the discharge door corresponding to the other side housing of the dust collecting separator 220. As an example and not by way of limitation, the locking member 224 may be in the form of a push button. The locking member 224 may lock the discharge door to form a closed trash holding space. And the user can open the discharging part 223 by operating the locking member 224, thereby discharging dust and the like. In an alternative example of the present disclosure, the discharge part 223 may be provided at one side surface of the dust collecting separator 220, and the end cover part 270 may be provided at the other side surface of the dust collecting separator 220, wherein the one side surface is the opposite side surface to the other side surface, and the two side surfaces are the side surfaces adjacent to the side surfaces where the first gas outlet 227, the second gas outlet 228, and the suction inlet port 226 are located.

Fig. 17 shows a schematic cross-sectional view of the dust collecting separator 220. Fig. 17 shows an automatic switching structure of the air duct switching device 250. Wherein the automatic switching mechanism may include a first spring 229. Wherein the first spring 229 may be disposed in an inner cavity formed by the housing of the dust collecting separator 220, the first spring 229 may be compressed when the first spring 229 is applied with a certain pressure, that is, the air channel switching device 250 may move toward the second air outlet 228 (leftward), and the air channel switching device 250 may move toward the first air outlet 227 (rightward) when the pressure of the first spring 229 is released. In this way, when it is necessary to install the cyclone separator 240 into the dust collecting separator 220, the air channel switching device 250 is moved leftward by the structure of the cyclone separator 240, and after the cyclone separator 240 is installed in place, the air channel switching device 250 is maintained at a position of a first state in which the first opening 251 opens the first gas outlet 227. When the cyclone 240 is removed, the tension of the first spring 229 causes the air duct switching device 250 to move rightward, so that the position of the air duct switching device 250 can be moved to a second state in which the first opening 251 is closed and the second gas outlet 228 is opened by the second opening 252 without installing the cyclone 240. By the mode, the situation that the first state and the second state are wrong due to the fact that a user forgets to stir the air channel switching device when the cyclone separator and the dust bag are replaced under the situation that the air channel switching device 250 is switched in a manual mode can be avoided. As shown in fig. 17, a first groove 2201 may be provided inside the housing of the dust collecting separator 220, and a corresponding engaging portion 2401 may be provided on the cyclone 240. After the cyclone 240 is mounted to the mounting structure 241, the snap 2401 may be snapped into the first groove 2201 to fix the cyclone 240 to prevent the cyclone 240 from being displaced. In case that the cyclone 240 needs to be taken out of the dust collecting separator 220, the user may operate the catching part 2401 such that the catching part 2401 is disengaged from the first groove 2201 to take out the cyclone 240.

According to an embodiment of the present disclosure, the dust collection separator 220 may be taken out or mounted to the inside of the housing of the dust collection device 200 by press-fitting. The self-locking structure of one embodiment will be described in detail with reference to fig. 19 to 24.

A first projection 2202 may be provided on an outer side surface of the dust collecting separator 220, wherein the first projection 2202 is in the form of a projection with respect to other portions around a housing where the first projection 2202 is located. For example, the first projection 2202 may be flush with the housing of the dust separator 220.

The self-locking mechanism may also include a latch 222. The latch may include a body portion and an extension portion. Wherein the body portion is positionable in and movable along the receptacle, and the extension portion extends from the body portion and is capable of flexing toward the body portion when subjected to a compressive force. Wherein the locking member 222 may be provided with a first concave portion 2221 corresponding to the first convex portion 2202, for example, on the extension portion. In the locked state, the first projection 2202 can be inserted into the first recess 2221 to lock the dust separator 220 to the housing of the dust collection device 200. According to an alternative embodiment, as shown in fig. 24, the lock member 222 may be further provided with a second concave portion 2222 so as to allow the extension portion to be elastically deformed, or to allow the first concave portion 2221 to be elastically deformed. Among them, the lock member 222 may be provided in the accommodating member 280 and may be slidable with respect to the accommodating member 280, and is restricted to be movable only in the left-right direction as shown in fig. 23. The receiving member 280 may be fastened to the housing of the dust collection device 200.

The self-locking mechanism may include a return tension spring 2801 and a return bar 2802, wherein one end of the return tension spring 2801 may be fixedly coupled to the receiving member 280 and the other end may be fixed to the locking member 222. One end of the reset lever 2802 may be disposed at the accommodating member 280 and the other end (free end) may be disposed at the locking member 222. Reset bar 2802 may be a reset wire, such as a rigid hooked rod. The lock member 222 may be provided with an entrance slot 2223 therein. Wherein the free end of the reset lever 2802 can slide in the entry slot 2223 and be guided by the wall surface of the entry slot 2223 into the locking slot 2225. When the reset lever 2802 is in a state of entering the locking slot 2225, the dust separator 220 is in a locked state. When unlocked from the locked state, the free end of the reset lever 2802 can enter the escape groove 2224, and guided by the wall surface of the escape groove, the free end of the reset lever 2802 can enter the communication groove 2226. And locking is again desired, the free end of the reset lever 2802 can reenter the slot 2223 until it is in the locking slot 2225. The free end of the reset lever 2802 is shown in a locked condition in the locking slot 2225 in fig. 23.

The locking and unlocking process will be described in detail below. When the locking is performed, the user can press the end cap portion 270 after putting the dust collecting separator 220 into the housing. The first projection 2202 of the dust collecting separator 220 is guided by the first guide surface 2227 of the locking member 222 into the first recess 2221. Meanwhile, the free end of the reset lever 2802 can enter the entry slot 2223 along the communication slot 2226, and guided by the wall surface of the entry slot 2223, the free end of the reset lever 2802 is in the lock slot 2225, restricting the movement of the lock member, at which time the reset tension spring 2801 is in a tensioned state. During unlocking, the user may press the end cap portion 270 again, at which point the free end of the reset lever 2802 will move out of contact with the locking slot 2225 and into the exit slot 2224, and then the free end of the reset lever 2802 moves along the exit slot 2224 into the communication slot 2226. At this time, due to the pulling force of the reset tension spring 2801 (the reset lever 2802 is not located in the locking slot 2225, and there is no constraint action of the reset lever 2802), the lock member 222 moves together with the dust collecting separator 220, during the movement, the first guide surface 2227 of the lock member 222 can contact with the interference surface 2803 correspondingly arranged on the receiving member 280, and since the receiving member 280 has a downward extending inclined surface, the interference surface 2803 can press the first guide surface 2227 downward, so that the first protrusion 2202 can be disengaged from the first recess 2221, and the dust collecting separator 220 can be ejected to the left side. The user can then pull out the dust collecting separator 220.

Fig. 26 shows an external schematic view of a dust collection apparatus according to another embodiment of the present disclosure. The dust collecting device 200 has a main function of sucking dust, debris, and other debris collected in a dust collecting part of the surface cleaning apparatus and storing the sucked debris. The dust collecting device 200 may be used in combination with the base assembly 100, or may be used in combination with the cleaning device 300. For example, the dust collecting device 200 may be detachably coupled to the upper surface of the base assembly 100, and the dust collecting device 200 may be integrally formed with the base assembly 100 after the coupling.

As shown in fig. 26, the dust collection device 200 may include a dust collection device housing 210 and a dust collection separator 220. Wherein the side of the dust collecting device case 210 is provided with an opening, and the dust collecting separator 220 can be insertably inserted into the dust collecting device case 210 through the opening. Wherein the dust collecting separator 220 is inserted into and removed from the dust collecting device housing 210 in a direction substantially parallel to a direction of a floor on which the base station is installed.
